SUMMARY: The Urban Heat Island (UHI) is shown to have affected U.S. temperature trends in the official NOAA 1,218-station USHCN dataset. I argue that, based upon the importance of quality temperature trend calculations to national energy policy, a new dataset not dependent upon the USHCN Tmax/Tmin observations is required. I find that regression analysis applied to the ISD hourly weather data (mostly from airports) between many stations’ temperature trends and local population density (as a UHI proxy) can be used to remove the average spurious warming trend component due to UHI. Use of the hourly station data provides a mostly USHCN-independent measure of the U.S. warming trend, without the need for uncertain time-of-observation adjustments. The resulting 311-station average U.S. trend (1973-2020), after removal of the UHI-related spurios trend component, is about +0.13 deg. C/decade, which is only 50% the USHCN trend of +0.26 C/decade. Regard station data quality, variability among the raw USHCN station trends is 60% greater than among the trends computed from the hourly data, suggesting the USHCN raw data are of a poorer quality. It is recommended that an de-urbanization of trends should be applied to the hourly data (mostly from airports) to achieve a more accurate record of temperature trends in land regions like the U.S. that have a sufficient number of temperature data to make the UHI-vs-trend correction.
The Urban Heat Island: Average vs. Trend Effects
In the last 50 years (1970-2020) the population of the U.S. has increased by a whopping 58%. More people means more infrastructure, more energy consumption (and waste heat production), and even if the population did not increase, our increasing standard of living leads to a variety of increases in manufacturing and consumption, with more businesses, parking lots, air conditioning, etc.
As T.R. Oke showed in 1973 (and many others since), the UHI has a substantial effect on the surface temperatures in populated regions, up to several degrees C. The extra warmth comes from both waste heat and replacements of cooler vegetated surfaces with impervious and easily heated hard surfaces. The effects can occur on many spatial scales: a heat pump placed too close to the thermometer (a microclimate effect) or a large city with outward-spreading suburbs (a mesoscale effect).
In the last 20 years (2000 to 2020) the increase in population has been largely in the urban areas, with no average increase in rural areas. Fig. 1 shows this for 311 hourly weather station locations that have relatively complete weather data since 1973.
This might argue for only using rural data for temperature trend monitoring. The downside is that there are relatively few station locations which have population densities less than, say, 20 persons per sq. km., and so the coverage of the United States would be pretty sparse.
What would be nice is that if the UHI effect could be removed on a regional basis based upon how the average warming trends increase with population density. (Again, this is not removal of the average difference in temperature between rural and urban areas, but the removal of spurious temperature trends due to UHI effects).
But does such a relationship even exist?
UHI Effects on the USHCN Temperature Trends (1973-2020)
The most-cited surface temperature dataset for monitoring global warming trends in the U.S. is the U.S. Historical Climatology Network (USHCN). The dataset has a fixed set of 1,218 stations which have records extending back over 100 years. Because most of the stations’ data consist of daily maximum and minimum temperatures (Tmax and Tmin) measured at a single time daily, and that time of observation (TOBs) changed around 1960 from the late afternoon to the early morning (discussion here), there was a TOBs-related temperature bias that occurred, which is somewhat uncertain in magnitude but still must be adjusted for.
NOAA makes available both the raw unadjusted, and adjusted (TOBs & spatial ‘homogenization’) data. The following plot (Fig. 2) shows how both of the datasets’ station temperature trends are correlated with the population density, which should not be the case if UHI effects have been removed from the trends.
Any UHI effect on temperature trends would be difficult to remove through NOAA’s homogenization procedure alone. This is because, if all stations in a small area, both urban and rural, are spuriously warming from UHI effects, then that signal would not be removed because it is also what is expected for global warming. ‘Homogenization’ adjustments can theoretically make the rural and urban trends look the same, but that does not mean the UHI effect has been removed.
Instead, one must examine the data in a manner like that in Fig. 2, which reveals that even the adjusted USHCN data (red dots) still have about a 30% overestimate of U.S. station-average trends (1973-2020) if we extrapolate a regression relationship (red dashed line, 2nd order polynomial fit) to zero population density. Such an analysis, however, requires many stations (thus large areas) to measure the average effect. It is not clear just how many stations are required to obtain a robust signal. The greater the number of stations needed, the larger the regional area required.
U.S. Hourly Temperature Data as an Alternative to USHCN
There are many weather stations in the U.S. which are (mostly) not included in the USHCN set of 1,218 stations. These are the operational hourly weather stations operated by NWS, FAA, and other agencies, and which provide most of the data the National Weather Service reports to you. The data are included in the multi-agency Integrated Surface Database (ISD) archive.
The data archive is quite large, since it has (up to) hourly resolution data (higher with ‘special’ observations during changing weather) and many weather variables (temperature, dewpoint, wind, air pressure, precipitation) for many thousands of stations around the world. Many of the stations (at least in the U.S.) are at airports.
In the U.S., most of these measurements and their reporting are automated now, with the AWOS and ASOS systems.
This map shows all of the stations in the archive, although many of these will not have full records for whatever decades of time are of interest.
The advantage of these data, at least in the United States, is that the equipment is maintained on a regular basis. When I worked summers at a National Weather Service office in Michigan, there was a full-time ‘met-tech’ who maintained and adjusted all of the weather-measuring equipment.
Since the observations are taken (nominally) at the top of the hour, there is no uncertain TOBs adjustment necessary as with the USHCN daily Tmax/Tmin data.
The average population density environment is markedly different between the ISD (‘hourly’) stations and the USHCN stations, as is shown in Fig. 4.
In Fig. 4 we see that the population density in the immediate vicinity of the ISD stations averages only 100 people in the immediate 1 sq. km area since no one ‘lives’ at the airport, but then increases substantially with averaging area since airports exist to serve population centers.
In contrast, the USHCN stations have their highest population density right in the vicinity of the weather station (over 400 persons in the first sq. km), which then drops off with distance away from the station location.
How such differences affect the magnitude of UHI-dependent spurious warming trends is unknown at this point.
UHI Effects on the Hourly Temperature Data
I have analyzed the U.S. ISD data for the lower-48 states for the period 1973-2020. (Why 1973? Because many of the early records were on paper, and at hourly time resolution, that represents a lot of manual digitizing. Apparently, 1973 is as far back as many of those stations data were digitized and archived).
To begin with, I am averaging only the 00 UTC and 12 UTC temperatures (approximately the times of maximum and minimum temperatures in the United States). I required those twice-daily measurements to be reported on at least 20 days in order for a month to be considered for inclusion, and then at least 10 of 12 months from a station to have good data for a year of that station’s data to be stored.
Then, for temperature trend analysis, I required that 90% of the years 1973-2020 to have data, including the first 2 years (1973, 1974) and the last 2 years (2019-2020), since end years can have large effects on trend calculations.
The resulting 311 stations have an 8.7% commonality with the 1,218 USHCN stations. That is, only 8.7% of the (mostly-airport) stations are also included in the 1,218-station USHCN database, so the two datasets are mostly (but not entirely) independent.
I then plotted the Fig. 2 equivalent for the ISD stations (Fig. 5).
We can see for the linear fit to the data, extrapolation of the line to zero population density gives a 311-station average warming trend of +0.13 deg. C/decade.
Significantly, this is only 50% of the USHCN 1,218-station official TOBs-adjusted, homogenized average trend of +0.26 C/decade.
It is also significant that this 50% reduction in the official U.S temperature trend is very close to what Anthony Watts and co-workers obtained in their 2015 analysis using the very best-sited USHCN stations.
I also include the polynomial fit in Fig. 5, since my use of the fourth root of the population density is not meant to perfectly capture the nonlinearity of the UHI effect, and some nonlinearity can be expected to remain. In that case, the extrapolated warming trend at zero population density is close to zero. But for the purpose of the current discussion, I will conservatively use the linear fit in Fig. 5. (The logarithm of the population density is sometimes also used, but is not well behaved as the population approaches zero.)
Evidence that the raw ISD station trends are of higher quality than those from UHCN is in the standard deviation of those trends:
Std. Dev. of 1,218 USHCN (raw) trends = +0.205 deg. C/decade
Std. Dev. of 311 ISD (‘hourly’) trends = +0.128 deg. C/decade
Thus, the variation in the USHCN raw trends is 60% greater than the variation in the hourly station trends, suggesting the airport trends have fewer time-changing spurious temperature influences than do the USHCN station trends.
Conclusions
For the period 1973-2020:
- The USHCN homogenized data still have spurious warming influences related to urban heat island (UHI) effects. This has exaggerated the global warming trend for the U.S. as a whole. The magnitude of that spurious component is uncertain due to the black-box nature of the ‘homogenization’ procedure applied to the raw data.
- An alternative analysis of U.S. temperature trends from a mostly independent dataset from airports suggests that the U.S. UHI-adjusted average warming trend (+0.13 deg. C/decade) might be only 50% of the official USHCN station-average trend (+0.26 deg. C/decade).
- The raw USHCN trends have 60% more variability than the raw airport trends, suggesting higher quality of the routinely maintained airport weather data.
Future Work
This is an extension of work I started about 8 years ago, but never finished. John Christy and I are discussing using results based upon this methodology to make a new U.S. surface temperature dataset which would be updated monthly.
I have only outlined the very basics above. One can perform similar calculations in sub-regions (I find the western U.S. results to be similar to the eastern U.S. results). Also, the results would probably have a seasonal dependence in which case that should be calculated by calendar month.
Of course, the methodology could also be applied to other countries.
In 1975 I took a course called In Urban Meteorology from Garstang and Pielke. This is consistent with what they taught 45 years ago.
Measuring land temperature is proxy for measuring global surface air temperature.
{and as side note, I would say global surface air temperature is proxy for measuring ocean temperature which is about 3.5 C, or could say the effects of ocean temperature is global surface air temperature}
Anyhow, in terms global air, it’s controlled by surface temperature and by most of the surface which is ocean surface.
And my question is why can’t we measure ocean surface by using satellites.
It’s said [by others] that average ocean surface temperature is about 17 C, but would guess this was said, even before we had satellites.
But apparently it’s uncertain about what exactly meant by ocean surface. As far as I am concerned is the skin temperature of ocean, averaged. Or 1 cm or less of ocean surface.
Also since people living on land, and most people are living in cities, it does not matter, why it’s warm or cold, they would simply want to know what the air temperature, is. And what feels like due to humidity is likewise, useful.
Also since people acclimate to whatever the conditions {and one’s mental state can affect how warm or cool it seems like} one could additionally focus on daily changes of temperatures- ie, the high or low temperature will be 5 or 10 C warmer, or colder, tomorrow, could be useful.
Or if going somewhere else, the differences between that place and place where you are- before you leave it- could be useful.
Anyhow, being in the Computer/Information Age, it seems UHI will become less significant as people should have less need to live in cities. And despite ever increasing energy usage of servers, would result reduction overall energy use. And when we put all the servers in orbit- it will be better.
My impression is that the best temperature measurements for the US continuous 48 states are:
USCRN (surface), and
UAH (satellite)
… but they are not included here.
I know USCRN is not long term but it is supposedly the best network of US weather stations.
The big picture is our planet has been warming since the 1970s, and no one knows the exact number. I would expect the government bureaucrats compiling the temperature statistics to be biased in favor of reporting too much warming, intentionally, or unintentionally.
Issues that matter more than UHI to me include NASA claiming a record high temperature in central Africa, where THERE ARE NO WEATHER STATIONS AT ALL.
Most important is the most basic question almost never discussed: Is global warming good news, or bad news?
We have all lived with global warming since the 1970s, and most of us have enjoyed it. Warming has most affected colder areas, mainly during the colder months of the year, and mainly at night. If that pattern of warming continues, that would be even better news.
Economic growth (cement, asphalt, bricks, etc.) in the vicinity of a weather station has to cause cause warming.
Whatever the urban heat island effect is, 71% of the planet is water, and not affected.
My old theory was that global warming was mainly caused by extraterrestrial space dust, and cosmic rays … but now I have a new theory: Global warming is caused by billions of people and animals exhaling carbon dioxide. More people and animals on the planet = more exhaled CO2 = more man made global warming. The solution is for people to be lazy — no exercise or strenuous work that would cause heavy breathing. I hope to win some kind of prize for this theory.
My new theory, is people don’t complain much about the temperature if living at the beach. And we could live in ocean settlements where everyone could live on the beach {and with low cost housing}.
Some people like to live in desert, but a lot people find tropical island paradises, appealing.
I think you present a well thought out argument here. Obviously I’d like to see this published and have other experts weigh in before drawing any conclusions. One obvious discrepancy that would need to be resolved is the +0.17C/decade trend from UAH TLT. Perhaps the +0.13C/decade throw out here is underestimated by 30%? Or perhaps there is a US based variation of the mid troposphere hotspot in play? Also, what does reanalysis show for the USA48 region?
All of these trends have error bars which are not well known. Also, the tropospheric trends cannot be expected to match the surface trends over such a “small” area (~2% of the Earth).
Much appreciated. Thanks.
“Black-Box Nature” (Translation-Opaque and Unscientific)…LOL!
Roy,
This work is hot trash. If there is a heat island effect why would it be linear with density? This seems like the obvious first step in the work. Determine the functional form of the
Why would extrapolating to zero density in Fig 5 give the “actual” change in temperature? Surely there’s some nonzero density where the heating effect on instruments is negligible. I think we could just as well argue from the data presented that the actual trend is 0.2 deg/decade and that a population density of 81 persons per km^2 has the exact same impact on the measurements as a population of 0 persons per km^2. You really need to put some real time in to show there’s any effect at all between 0 and 81 persons per km^2. There’s barely any data below 16 persons per km^2. This seems to correspond to warming of 0.18 deg/decade.
The correlations themselves are also hot trash. The trends that you claim belong to the data presented is very difficult to believe. The slope of your linear fits can be easily moved in one direction or the other without significantly changing the correlation. In Fig 2, you do a linear fit to one set of data and a 2nd order fit to the other.
I cannot understate the importance of the following line: Homogenization adjustments can theoretically make the rural and urban trends look the same, but that does not mean the UHI effect has been removed.
That’s the first-order homogenization algorithm. NOAA uses a second homogenization algorithm to blend and obscure even more detail. And that’s primarily on the land-surface record; the ARGO buoy system has its own adjustment errors covering 70% of the globe (each data point representing ~200k sq kms.)
If the temperature record was robust enough in 1880 with as few widely dispersed locations as existed back then, then the same level of granularity can suffice today to establish and track a GMT. But if not, then one has to question with what veracity the pre-1950 global temperature record actually conveys — and with it, the entirety of the 1:1 CO2-to-GMT relationship NOAA and NASA are trying to paint themselves into.
Still not persuaded!
If I suddenly build an airport or a small town in a rural area, the average temperature will be suddenly warmer than the surrounds due to the UHI effect. But, and consider this carefully, thereafter if nothing else changes, the temperature does not continue increasing. It simply remains at the higher value. There is no reason for it to continue increasing ad infinitum.
i.e. relating temperature TRENDS to absolute population is faulty logic. The UHI effect can only be detected by relating temperature TRENDS to population TRENDS.
“Fig.2. USHCN station temperature trends are correlated with population density, which should not be the case if the Urban Heat Island effect on trends has been removed.”
Wrong! Even if there is a slight correlation between population and temperature trends, this is an erroneous conclusion. What is really happening is that the more densely populated regions are most likely GROWING at a faster rate than the less densely populated regions.
The bottom line is that trying to account for UHI effects based on population only is misleading.
And yet, with the same population in prosperous countries, prosperity increases. It does matter what you imagine how the way things work: what matters is the data shows the warming trends increase with population density.
I also did multiple regression with population densities in 2000 and 2020, to see if an increase over time might (reasonably) be the cause. The results showed a weak dependence on population increase, but just the population density in 2020 explains most of the variance in station temperature trends.
But you are free to disbelieve it.
If you found a weak relationship between aggregated temperature trends and population trends then the obvious conclusion is that there is no relationship between the UHI effect and aggregated temperature trends.
This indicates that the observed aggregated temperature trend for the USA is not artificial.
i.e.you are arguing against yourself.
It may seem intuitive that population trend should be the primary variable. But I think that is only the case if you ignore how humans affect their habitat. They arrive then they develop. As Roy points out prosperity increases.
One also needs to recognize that the greenhouse effect isn’t about making things hotter its about retention of heat and anthropogenic fossil fuel emissions is only one means of retaining heat.
“the population density in 2020 explains most of the variance in station temperature trends.”
If you are talking about Fig 2. The correlation looks extremely poor.
Zero correlation is entirely likely.
where is your math on that Nate?
I agree the correlation, R2 = 0.096, is very low. Maybe not zero but it only explains 10% o the variance.
Yeah. And even that could well be with error.
arggh
within error
Yep and when you consider that Roy’s analysis suggests half the warming variance is potentially UHI that puts the other half of the warming in the error bars as well.
“suggests half”
Maybe half, maybe 0
I know exactly what you are saying and I don’t disagree, but I’m not sure how much that matters. I was thinking that urbanization had already run it’s course by 1980. In that regard I’m not sure how much of a TREND population density has exhibited during this time. I think Dr. Spencer’s point is worthy of more investigation.
The problems I see are 1) there are other explanations for the arrangement of the red data points in Dr. Spencer’s analysis other than UHI contamination 2) the potential discrepancy between the conclusion of +0.13C/decade and other analysis.
It is important for all of us to remember that the UHI effect itself is not the problem. It should not be removed from the individual station records. The problem is the use of urban stations as proxy’s for grid cells that are predominantly rural. We need to take care that the UHI effect is removed when using urban stations in this manner. What I’m getting at is that with 25×25 km grid cells many of these cells are predominantly urban especially in the northeast. Removing the UHI signal from that grid cell would be just as wrong as applying it to nearby rural grid cell. In this context you can see why the analysis in figure 2 above could be misleading since it implies that a regional or global mean temperature will be biased by the UHI when in reality it might not. It depends on how that mean temperature calculation accounts for the UHI effect. There is a distinction that needs to be made between the warming trend of individual stations and the warming trend of a robust (UHI accounted for) regional mean temperature.
And a corollary to the above is that the UHI effect could create a cooling bias in regional and global mean temperature calculations if handled improperly. This would be the case if a grid cell were large enough to have significant rural and urban areas. As rural station counts increase and urban station counts decrease over time in this cell may cause the cell to underestimate the temperature due to the overweighting of rural stations. In fact, this effect may explain some of Berkeley Earth’s conclusion that the UHI bias is actually more likely to be negative after 1960. If such mishandling were to be occurring it would not detectable with Dr. Spencer’s analysis above.
It is for these reasons that I remain skeptical.
I would like to go one step further and suggest that apparent population/trend correlations could also possibly mask the fact that the background warming trend varies geographically.
You might think you have detected a correlation when, in fact, the real reason is that the largest trends occur further north, and that is where the higher density population cities are located.
i.e. evidence of correlation does not guarantee evidence of cause and effect.
Exactly.
“In the last 20 years (2000 to 2020) the increase in population has been largely in the urban areas, with no average increase in rural areas.”
Curious to check against the “pristine” US Climate Reference Network.

The CRN starts only at 2005, but I would have thought that there would be some differences with NOAA’s US temp record if urbanisation has an impact over the last 16 years.
However, USCRN has warmed ever so slightly more than the official record since 2005 (1.44 vs 1.40 F/decade).

You are right.
Your graph reminds me a comparison of two stations in Alaska I made two years ago, between
– a ‘bad’ station at Anchorage Intl Airp
– the ‘pristine’ CRN station Kenai ENE, distant by 50 km, in the middle of nowhere.
https://drive.google.com/file/d/1OhCuDiAFUT80Ws4S8XopciaWQTp4rorn/view
Absolute temperatures in Anchorage are at least 2 C higher, but the departures wrt a common reference period (here: 2011-2018, due to Kenai ENE’s short lifetime) look quite nice.
I made several comparisons between USHCN, USCRN, GHCN daily US, including the 71 USHCN stations pompously certified ‘well sited’ by Watts’ surfacestations.org.
The best is that these 71 stations, when compared with about 8000 GHCN stations in the US, show on average less warming in the past and more warming in the present! The data is till 2019, I’ll update the graph.

Great.

J.-P. D.
This is another piece of evidence that suggests the relationship between population density and temperature as visualized in figures 2 and 5 could be caused by something other than UHI contamination at least after 2005.
Point #1
I have seen the assumption that maximum temperature occurs generally around noon and minimum around midnight written in various discussions but my observation differ markedly. I wonder if actual data supports those particular times of max/min in very many places?
Here, and in a couple of relatively nearby places I’ve lived and worked over the past 30 years or so (withing a 50 mile radius), daytime temperatures peak around 6 PM during the hottest part of the year, falling back to (or moving up from, depending on season) around 3 PM during the coldest part of the year. Noon seems never to be even near the hottest except on heavily overcast winter days with little air movement where the temperature might not vary much between around 10 or 11 AM to somewhere near sundown.
I am often up until the wee hours, even until after the sun is up. While they are no doubt inferior to official weather thermometers, my two thermometers (front and back yards) often continue to show slowly decreasing temperatures until about the time the sky starts getting lighter, which is always long part midnight.
So, once again, does actual data support the idea that maximum is around noon and minimum around midnight anywhere?
Point #2
Even more important, or so it seems to me, if there are hourly temperature reading (more frequent than hourly might be better) why not use the actual recorded high and recorded low, regardless of when they occur?
My understanding might be frightfully deficient, but why does the time make any difference at all? I have read that TOB adjustments make the averages (or perhaps trends) either higher or lower, depending on how they are done, but if the actual highs and lows are known, would it not be more reasonable to just use them, with no adjustments, no assumptions?
Point #3
Also, the highest and lowest temperatures seem quite deficient for representing anything much. Some integration of temperature over time would provide a more realistic view of what actually effects the environment, the people, animals, and plants within it, but then reality could be even much more complicated than that. Here, air movement is extremely important for heat and cold.
The air is sometimes very still for days on end. During the high temperature seasons, that can mean that at midnight the temperature hasn’t fallen all that much from the day’s high. It is difficult to lower the house’s interior temperature much.
On the days with good evening breezes the temperature can come down 20 degrees fairly quickly once the sun has set. In the colder seasons a stiff wind can make even moderate daytime temperatures quite uncomfortable and lower the inside temperature quite markedly overnight. But, I guess all that is a completely different discussion.
My understanding might be frightfully deficient, but why does the time make any difference at all? I have read that TOB adjustments make the averages (or perhaps trends) either higher or lower, depending on how they are done, but if the actual highs and lows are known, would it not be more reasonable to just use them, with no adjustments, no assumptions?
The problem with the time-of-observation is that depending on when the observer records the min/max from the instrument she will unshiftingly double count some mins or maxes. It is important to understand that reading the instrument involves “resetting” it for the next observations. This has little effect on the temperature trend if the TOB stays consistent. But if you switch from say a PM reading to an AM reading you switch the direction of the double count problem. That creates an instant discontinuity in the station’s time series. Now imagine hundreds or even thousands of stations making the switch from PM to AM over many decades. That is where part of the cooling bias comes from. Another component is the transition to MMTS instrumentation.
So I think the answer to your question is that highs and lows as they appear in the record are not always correct and it has nothing to do with the quality of the instrument. It has everything to do with how the instrument was used. For example, if you read the instrument at say 6:00am the instrument will get reset and possibly record a lower value 6:01am which will be applied to the following day even though the low on the following day may have actually be higher. AM observations cause more double counting of lows than double counting of highs. And that’s exactly what happened. Stations slowly began switching from PM to AM observations.
This article is all about automated systems. There is no problem with observers.
This subthread is about time of observation bias, which is not about automated systems.
I’ll take a stab at your #1. The 1200/0000 times are UTC (Zulu), which is -4/-5 for local time on the east coast to -7/-8 on the west coast (depending on whether we are in daylight savings time or not). 1200Z is decent enough for low temps on the east coast, little early for the west coast where 0000Z is decent for high temps on the west coast, little late for the east coast.
Am I allowed to be practical? It seems that urban density has 2 effects. One is the size of the urban area, and the other is the effect of density itself. It is reasonable to assume that increasing the size of the urban area would have a diminishing effect. As growth moves away from the measuring location it should have less effect. One the other hand, construction of larger and taller buildings could have an effect, and vacant lots near the measuring location that get filled in, should definitely have an effect, so I believe the data is supported by a physical analysis.
Taller buildings could shade the weather station, introducing cooler temps after construction.
Changing urban environments don’t always warm the trend for a given station. Station moves from urban area to airports also cooled the record.
Many airports have had a lot of economic growth in the vicinity, and that should cause some warming in the decades after the initial move of a weather station, from an urban environment, to an airport.
In addition, air traffic has increased a lot since the 1960s, as air travel became less expensive. More and more planes using an airport = more heat.
Richard Greene
You write above
” More and more planes using an airport = more heat. ”
Are you sure?
Last year I made some ‘intra CONUS’ comparisons between the well-known set of 71 USHCN stations estimated ‘well sited’ by Watts’ surfacestations.org volunteer team (*) and other, much bigger sets of CONUS stations within the GHCN daily data set.
One comparison was between the well-sited station set and all GHCN daily stations operating within CONUS.
One was between the well-sited station set and all 1260 GHCN daily stations operating at CONUS airports:

Don’t you think that if a majority of airports had any UHI problem, this then would not be visible in the chart? Hmmmh.
Of course one could refine the software process by looking, for each airport, at the nearest rural station, and compare the resulting two time series.
I doubt that we would obtain something dramatically different.

Las Vegas may be a poor example because the desert does not have much plant growth, but the model is probably a good one. I know for a fact that McCarran airport was out in the desert 35 years ago. Today it is literally surrounded by new development. If this had occurred in a forest or grassland area, the effect would have been dramatic. The growth of the airport itself with bigger buildings and parking lots would also contribute.
The Detroit City Airport was located in an urban area with little room for economic development. Then a new Detroit Metro Airport was opened far from the city of Detroit. Over time, the area around that suburban airport became filled up with huge parking lots, hotels, motels, and restaurants. The deregulation of airline ticket pricing led to flights as low as $100 from New York to Detroit — air traffic increased a lot. More recently the airport was significantly expanded with more terminals.
The Dallas Fort Worth airport had very little air traffic when it was first opened. It is MUCH busier now.
On the other hand, La Guardia Airport in NYC was always in an urban environment with little room for economic development in the vicinity.
Every airport is different.

“Because there is not an obvious meso‐scale metric that determines the impact of urban form on temperature in all situations, we examined four different measures of urbanity that are available as georeferenced datasets: satellite‐derived nightlights, urban boundary delineations, percent of impermeable surfaces, and historical population growth during the period where high‐resolution data is available (1930 to 2000).”

“More people means more infrastructure, more energy consumption (and waste heat production), and even if the population did not increase, our increasing standard of living leads to a variety of increases in manufacturing and consumption, with more businesses, parking lots, air conditioning, etc.”
Actually in the US, our per-capita energy use has been extremely

You keep posting stuff that has no relevance to his data. Do you just do Google searches until you come up with something you think contradicts his point? He is trying to get an accurate temperature record. What are you trying to do?
“no relevance to his data.”
Man is it hard to get you to use your logic chip, Stephen. Maybe it needs to be replaced.
Then please show how it is relevant to his data? You post a chart of per capita energy consumption. He posted something about air conditioners, infrastructure, population increase. So if 10 people are consuming 20KW/day each in an area and then a year later 20 people are consuming 20KW/day in the same place, who’s going to put our more energy? The 10 people or the 20 people? Please explain instead of posting something that has no meaning.
Trying showing us your mastermind logic chip.
He also said this “and even if the population did not increase…”
Jeez…how did you miss that?
That was what my post was relevant to.
Yes, but per capita consumption doesn’t reveal how the energy is used. Cars have increasingly gotten more efficient. Air conditioners and heat pumps have gotten more efficient. Motors and batteries are more efficient. So, per capita consumption could stay flat while people are using more energy to affect temperature and less energy that doesn’t affect temperature. There is no way of knowing with a general chart you linked.
I guess too I wanted to show you what it feels like. You seem to have a problem with everything he posts. He doesn’t conform to the big climate agenda, so you have a problem. He seems like a scientist who’s in search of the truth. I don’t always agree with him, but he’s what we need, truthseekers.
I have a problem when he makes weak arguments. They are almost always intended to support a political agenda. You like that agenda, so naturally will eat it up without skepticism.
stop being such a nincompoop Nate.
Roy is simply showing a different UHI result using hourly station data where available rather than tmin tmax data that gets fiddled with on time of day adjustments.
I have done enough sampling to know you can’t fix bad data. All you can do is substitute something else. Warming trends have been created by such fiddling.
So you sit here whining about Roy getting an idea to reduce data fiddling and substitution and you whine like a banshee stuck by a spear.
The real problem here is a lot of data on variation that have little or no visible effects.
Its not like the temperature of a town went up and the residents dropped like flies. . . .images of that is specially reserved as massive extrapolations to feed young impressionable minds.
“you whine like a banshee stuck by a spear.”
Not really. I simply pointed out some issues with the analysis. As have others. These are legitimate issues to raise.
Skeptical opinions, different from the party-line are allowed in this forum. But some of you, like the Republican party, are really into Cancel Culture right now.
What are the uncertainties of the linear fit in Figure 5?
Given that this is being extrapolated outside the data range, and the linear fit is based on a forth root scaling, it could well be that the confidence intervals at 0 are very large, and could easily include the “official” warming rate.
Ditto. The R^2 of 0.096 on that linear fit in figure 5 makes me think the standard error of that trend could very well exceed the slope of 0.03.
However when we start about trends within error bars practically nothing survives in the world of AGW beyond normal variation.
For the very reason of this article this is why I think oceanic sea surface temperatures are a much better indicator of just how much or little global warming is taking place, over the long run.
Even better…total oceanic heat content.
Bdgwx, I believe the surface temperature is a good indicator of the mixed layer and since we don’t have total ocean heat content there’s no way to use it anyway. The mixed layer is in contact with the atmosphere. It’s where changes will show up first.
Interestingly, we find the SSTs agree with UAH (and CERES) almost perfectly. Which is a good indication they are accurate.
https://woodfortrees.org/plot/uah6/from:1979/to/plot/uah6/from:1979/to/trend/plot/hadsst3gl/from:1979/to/offset:-0.35/plot/hadsst3gl/from:1979/to/offset:-0.35/trend
Using SSTs back to 1940 gives a a trend of .07 C / decade. I think this is the most accurate figure. Going back further reduces the impact of the AMO, PDO and ENSO on shorter term trends.
https://www.woodfortrees.org/plot/hadsst3gl/from:1940/to/plot/hadsst3gl/from:1940/to/trend
This leaves us with one more significant factor. Increasing ocean salinity. It could be responsible for most of what is left. That would agree with the experimental evidence which shows almost no warming potential for increases in CO2.
https://www.scirp.org/journal/paperinformation.aspx?paperid=99608
” … and since we dont have total ocean heat content theres no way to use it anyway. ”

‘We’ know: your genial, fantastic WFT graphs ARE the real, actual science!

J.-P. D.
At least WFT graphs are based on real data and not based on opinion and models. The fact you would think otherwise pretty much explains everything about you.
How would you measure OHC using scientific principals?
“Another science free climate paper. Full of assertions with zero actual science.”
Wachu talkin bout RichM? Looks like normal science, with loads of ocean measurements. Exactly what we need to understand climate change.
Multi-proxy studies are like having multiple variables. Play with 3 variables and you can create and elephant. Add a 4th and you can make its trunk wiggle.
The upper ocean could be warming for a variety of reasons. If the ocean bottom is cooling it will create less vertical mixing in the ocean by increasing stabilization of the temperature profile of the ocean and reduce upwelling. All of that could be part of a LIA recovery.
Upwelling is a very evident process but is poorly measured. Ocean mixing is what gives us ENSO and multi-decadal ocean oscillations and most likely longer lived variation as well.
Much is simply handwaved away in climate science. It is simply assumed that the LIA did not occur but its rapid dip was a natural consistent cooling only interrupted by the industrial age. Sloppy science at best. Instead the 400 to 600 year descent into the LIA may well have been reversed by a reversal of the causes of the dip. . . .a reversal that likely occurred over 300 years ago.
” If the ocean bottom is cooling ”
The ocean bottom is ~ constant 4 C. This is the temperature of highest density water, which ends up on the bottom.
https://www.windows2universe.org/earth/Water/temp.html
Temp profile
Not 4 C for seawater. Closer to 0 C.
Ocean water freezes at about -2C
Yes w density maximum a bit higher than that.
Richard M says: ”This leaves us with one more significant factor. Increasing ocean salinity. It could be responsible for most of what is left.”
That sounds pretty crazy. Why would ocean salinity increase?
NOAA says this: ”Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these “salinity raising” factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.”
Hmmm, indeed mankind has created a lot of water impounds but irrigation is increasing and glaciers are supposedly melting. What goes up must come down.
Have you ever thought about doing this for Europe? afaict theyve seen more warming over the last 50 years.
And with low population density increase.
” U.S. temperature trends in the official NOAA 1,218-station USHCN dataset”
…
“This is an extension of work I started about 8 years ago, but never finished.”
The lapse of time shows. USHCN ceased to be the official data set in March 2014. Since then, the NOAA calculations have been based on the much larger ClimDiv dataset. So this analysis is pointless.
“Instead, one must examine the data in a manner like that in Fig. 2, which reveals that even the adjusted USHCN data (red dots) still have about a 30% overestimate of U.S. station-average trends (1973-2020) if we extrapolate a regression relationship (red dashed line, 2nd order polynomial fit) to zero population density. ”
This is the discrepancy underlying most of these results. No-one but Dr Spencer is trying to fit to zero population density. That is fantasy world stuff. The US has a population, and it isn’t going to go away. NOAA, and others who measure the temperature, are trying to measure what it actually is, population and all. They try to remove a UHI bias in the sampling of the US temperature, but they don’t try to emulate that fantasy.
“They try to remove a UHI bias in the sampling of the US temperature, but they don’t try to emulate that fantasy.”
Nonsense.
The actual UHI adjustment is extremely tiny — almost as if NASA wanted to claim they made a UHI adjustment, but didn’t want it to affect their beloved global warming trend.
The reason the adjustment is so small (less than 0.1 degrees in a century) is that roughly half the so called UHI “adjustments” are cooling (?), and half are warming, so the net change is near zero.
That result makes no sense, and I suspect science fraud.
The main problem with surface numbers is not UHI, it is insufficient coverage, especially before World War II
And the result is excessive guessing (infilling) of missing data .. guesses that can never be verified.
So the global average temperature is whatever the government bureaucrats tell you it is. And when they claim a record high temperature in central Africa, where there are no weather stations, just shut up, and don’t complain.
If you don’t trust government bureaucrats, and their infilling, and “adjustments”, the only other choice is UAH.
UAH requires much less infilling, and is measured in a more consistent environment … where the greenhouse effect actually occurs.
Every time I ask for details on the percentage of temperature numbers that are estimated (infilled) for the global average surface temperature statistic, I get a blank stare from climate alarmists.
And that includes Mr. Stokes.
RG said: The actual UHI adjustment is extremely tiny almost as if NASA wanted to claim they made a UHI adjustment, but didnt want it to affect their beloved global warming trend.
It’s not just NASA though. Others have come to the conclusion that the effect is small when applied to global scale averaging. I’ve noticed that those that come to a different conclusion do not produce their own global mean surface temperature datasets. Don’t you find that odd?
RG said: That result makes no sense, and I suspect science fraud.
This is the problem with blogs like this. If someone does not understand something they immediately invoke fraud and conspiracy to rationalize their position.
RG said: The main problem with surface numbers is not UHI, it is insufficient coverage, especially before World War II
Yeah…coverage sucks. I wish we had a station for every sq km that has recorded data for the last 2000 years. But the reality is that we don’t so we have to make the most of what we do have.
RG said: And the result is excessive guessing (infilling) of missing data .. guesses that can never be verified.
When doing spatial averaging with inhomogeneous data you have to infill no matter what. At least NASA and Nick Stokes do it with verified mathematical techniques instead of just assuming empty grid cells inherit the global mean. And although there are legitimate criticisms on the details of these techniques nobody has any serious fundamental objections to their use. In fact, of those that did express legit skepticism they conceded that these techniques are necessary to decrease the uncertainty envelope.
And I bet you anything you could figure out how one could verify the “infilling” in a matter of minutes. Take a stab at it. The most mind numbingly obvious technique has been mentioned several times on this blog.
RG said: So the global average temperature is whatever the government bureaucrats tell you it is.
I’ll let Nick Stokes speak for himself, but I doubt he has government bureaucrats breathing down his neck.
RG said: If you dont trust government bureaucrats, and their infilling, and adjustments, the only other choice is UAH.
Sorry to bust up the party, but UAH makes adjustments. In fact, they don’t even directly measure the temperature. They have to use a complex model to map O2 microwave emissions to meaningful temperature values. Then they employ a finely tuned weighting function to derive the LT temperature from MT, TP, and LS products. And if you saw my post a few days you would know that even the smallest change in this weighting function makes for huge changes in the final LT result. And then even at that it is not even the surface temperature. Dr. Spencer mentions in this very blog tropospheric temperatures have little correlation to surface temperatures on regional scales like USA48.

Another non-answer from perfesser bdgwx
It requires just one number, a percentage, to answer my question about the percentage of infilling, and you have provided a web page … not the answer.
What is the percentage, Mr. Smarty Pants?
I have to suspect you have no idea.
I question the fact that roughly half the NASA UHI adjustments reduce global warming, and roughly half increase global warming.
Economic growth near land weather stations (cement, asphalt, bricks, buildings etc) should increase measured warming very gradually over time.
The UHI number may be small, but almost half the “adjustments” should not REDUCE global warming.
If you can explain (I doubt it) why so many UHI adjustments increase global warming, please share that knowledge with us.
In my opinion that pattern of adjustments smells of science fraud.
Your claim:
“If someone does not understand something they immediately invoke fraud and conspiracy to rationalize their position.”
That is your childish character attack, typical of leftists.
RG said…It requires just one number, a percentage, to answer my question about the percentage of infilling, and you have provided a web page … not the answer.
It is literally right there at the top of the page. And it’s not just one number. It changes over time. That’s why I gave you link.
RG said: The UHI number may be small, but almost half the “adjustments” should not REDUCE global warming.
Why? What evidence can you present that this should not occur?

RG said…That is your childish character attack, typical of leftists.
Whoa…time out. First…I think you have me confused with someone else. I’m not a leftist. Second…I’m not attacking your character at all. I’m sure you a great person and I’d imagine we’d probably get along just fine if we met in person. In fact, I’m certain we would. But being a great person is not an excuse for someone to invoke fraud and conspiracy to rationalize their position.
“It requires just one number, a percentage, to answer my question about the percentage of infilling, and you have provided a web page”
A webpage that tells you not only the percentage of coverage, but also what that coverage is depending on which year in the record. More than you asked for, and why a simple single number doesn’t cover it.
I don’t think you try to understand, you seem to only want to discredit.
I’m still waiting for the number. Of course it will vary from month to month. I don’t expect every month. The most recent month will do. I’m waiting very patiently. I ask questions. You fail to answer them. I would think you are more curious than that, being a big fan of surface temperature numbers.
Data that follow are a few years old:
… the National Climatic Data Center (creatred) a US dataset
with a large number of “contiguous United States” weather stations, called the U.S. Historical Climatology Network
( USHCN ).
Almost all of the station records are fairly long and complete — there are several rural and urban stations located in each of the U.S. states.
Of the 1,218 USHCN stations about 23% are very rural, and about 9% are highly urbanized.
Both US subsets show similar trends:
— Warming from the 1890s to the 1930s
— Cooling from the 1930s to the 1970s
— Warming from the 1970s to the 2000s
Most of the US weather stations with records going back
to the late-19th century (or earlier) are urban stations.
( The longest station records are mostly in Europe, and
North America), far from a good global distribution.
The rural US stations agree with the urban stations that the 1990s-2000s were warmer than the 1960s-1970s, but disagree
over how much.
The urban US stations imply the 1990s-2000s were the the warmest decades on record, but the rural stations imply it was as warm in the 1930s !
NASA-GISS divided their weather stations into “urban stations” and “rural stations”.
Since 2010, that division was based on night-light intensity in the location of the station (using satellite data).
For every station identifies as “urban”, there is an individual urbanization bias adjustment, using the following method:
A “rural average” is calculated for the urban station by averaging together the trends of all of the rural neighbors in a 500 km radius (or 1000 km, if there aren’t enough within 500 km).
The difference between the urban station record and the rural average is then calculated, and assumed to be “the urbanization bias”.
The urbanization adjustment is calculated by approximating the difference using a linear fit.
However, because urbanization is not a simple linear process, they use a two-part adjustment.
They calculate two linear fits – “Leg 1” is the linear fit for the first part of the record, and “Leg 2” is the linear fit for the second part of the record.
About half of all the linear adjustments their computer program calculates say the UHI causes cooling, rather than warming.
“Urbanization bias” due to “urban cooling“ ?
Details:
15% Both adjustments are “urban warming”
9% Both adjustments are “urban cooling”
76% One adjustment is “urban warming, and the other adjustment is “urban cooling”
The “urban cooling” adjustments do not make sense.
They do not make sense because I am not gullible, as you are, when government bureaucrats tell me what to believe!
“I’m still waiting for the number.”
Despite the figures being linked for you, you want someone to write in a comment here?
Since 1985, the global coverage has been roughly 81%.
It’s a very simple matter of looking at the chart, adding the North and South hemisphere results and dividing by two.
What issue resides within you that you are incapable of doing this yourself when it is laid out for you? Is it arrogance? Incompetence?
Whatever the answer, it will also be the reason you fabricate so much.
“The urban US stations imply the 1990s-2000s were the the warmest decades on record, but the rural stations imply it was as warm in the 1930s!”
I call BS. I’d ask you to substantiate, but I expect that you will not bother, as usual. Others provide links to help you out, but the street is one way for you.
That web page does not answer my question.
You have not answered my question.
Bdwgx has not answered my question.
Nick Stokes has not answered my question.
I’ll make it as easy as possible:
Pick any one month, of any year, and you tell me what percentage of the temperature numbers in the global average for that month have been estimated (by “estimated”, I mean the number was infilled by government bureaucrats, and NOT based on actual measurements FROM THAT WEATHER STATION)
It seems like an easy question.
It seems like climate alarmists would want to know the answer.
So what is the answer?
On February 12, 2021 at 12:48pm, long after his bedtime, “Barry” provided a non-answer to my question.
Of all the numbers used to calculate a global average temperature in any month, I wanted to know what percentage were made up numbers, aka infilled.
Obviously, a surface grid with no weather stations at all requires a made up number. The “coverage” number may explain this infilling.
But there will be other weather stations, with some missing data, that also require a made up number. The coverage number is not likely to explain this infilling.
My question is what percentage of all the numbers used to compile a global average temperature are made up numbers rather than real data.
The percentage for any one month would be sufficient.
I would prefer data from long ago, perhaps before World War II, but any month will do.
In my opinion the “coverage” number does not reveal the TOTAL percentage of infilling … although it is ALREADY large enough to make the official claims of a +/- 0.1 degree C. margin of error, for the global average temperature, appear to be science fraud.
RG,
Here is a comprehensive breakdown of the GISS uncertainty.
https://csas.earth.columbia.edu/sites/default/files/content/Lenssen_et_al-2019-Journal_of_Geophysical_Research__Atmospheres.pdf
The uncertainty is actually less than 0.1C and has been since at least 1960.
And I guess I don’t understand your question regarding the percentage. Can you provide more details so that I can better understand it?
RG,
Something that might help facilitate the discussion is the GISTEMP methods paper.
https://pubs.giss.nasa.gov/docs/1987/1987_Hansen_ha00700d.pdf
Read through and make sure you understand how GISTEMP computes the global mean.
Unfortunately until I get more clarification on your question I’m sticking with the answer that there is about 80% coverage which means 20% of the subboxes are “infilled”. Note that “infill” does NOT mean that temperatures are simply “made up”. It means that the subbox inherits the temperature of its neighbors. The full procedure is actually quite clever. If you want we can discuss it to ensure there is mutual agreement on the way it works.
I don’t know why all the comments do not have a “reply” button or maybe it’s just my computer. Or a conspiracy!
If 20% of surface grids were infilled, then that is already a lot of wild guessing.
Far too much wild guessing to claim a +/- 0.1 degree C. margin of error, EVEN TODAY, much less in the 1800s.
And don’t tell me that infilling in place of ACTUAL MEASUREMENTS is not wild guessing.
At best it is “educated guessing” by people biased to want more global warming, for job security, and to support their predictions of fast global warming.
“Educated guessing” by people likely to be biased = wild guessing.
While there are surface grids with no weather stations, there are also surface grids with one of more weather stations, some of which may have some, or all, missing data for any given month.
Those missing data must be infilled too.
I have evidence that infilling of data points for any given month is higher than 20 percent … and 20 percent is already a lot of guessing without data.
In addition, when raw temperature data are “adjusted”, for any reason, they are no longer data.
They become opinions of what the data would have been if measured accurately in the first place.
The “adjustments” become suspicious when they are done a month, year, or many decades AFTER the actual measurements, or there are multiple “adjustments” of the same data.
Any organization that claims a +/- 0.1 degree C. margin of error for temperature statistics that start in the 1800s, with few land weather ,stations, and ocean measurements with a bucket and thermometer used by untrained sailors, almost entirely in Northern Hemisphere shipping lanes, is practicing science fraud.
RG,
There is a lot of rhetoric in your post that I could address, but I’m not sure it would do any good at this point.
Let me just cut to the chase. How would YOU go about computing the global mean temperature from GHCN and ERSST?
bdgwx says:
”This is the problem with blogs like this. If someone does not understand something they immediately invoke fraud and conspiracy to rationalize their position.”
You are doing the same thing bdgwx. How does saying something involves fraud and conspiracy have any reflection on what they understand?
I agree with you that it is not fraud. The only fraud that exists in the world of academic science is plagiarism and data falsification. And technically even that isn’t fraud its simply grounds for dismissal.
Academic science is designed for scientists to glean what they want out of it. Grant science is designed for their funders. And science designed for the public like medicine you need one helluva lot more vetting than the science community’s opinion of it.
The science community’s opinion is whatever is best for science like any other community that enjoys free speech advocates for what is good for them. Some communities don’t enjoy those freedoms as they operate under professional standards as licensed doctors, engineers, accountants and more and must limit what they offer in that capacity to the public.
So if its a conspiracy its not a criminal conspiracy at least and in the academic world its only grounds for dismissal if it runs against the internal politics of the hirer. . . .which course is what tenure was designed to protect.
No. I do not invoke unsubstantiated accusations of fraud to justify my position. My position can be justified by the abundance of evidence. In other words, I do not accept AGW just because some contrarian may have presented his argument in bad faith. I accept it because of the evidence.
I’m not even sure contrarian viewpoints even when presented in bad faith could rise to fraud since fraud generally requires an expectation of credibility and accountability. Bona-fide experts generally have a high bar of accountability while non-affiliated contrarians have a very low bar if there is any accountability at all that is. And I happen to think it is completely fair. That is bona-fide experts trying to legitimately advance scientific understanding should be held to a higher standard while those that only criticize without providing any useful insights to science and who invoke unsubstantiated accusations of fraud themselves should have the right to continue to do so unimpeded. Science will always win in the end regardless.
Bdgwx you claim your point of view is supported by experts. So does everybody else.
There is plenty of just bad papers out there that get stamped by funders and powers that be as the best science available when its questionable its even science.
You talk about high levels of accountability for so-called bona-fide experts as if there was any reality at all to that. But you don’t say what that accountability is.
An expert is somebody who should understand enough about a topic top to bottom to provide reliable advice. Instead, science trundles along like Michael Crichton outlined in State of Fear; where one scientist accepts officially anointed nonsense and expounds on it as it were a certain truth.
It isn’t codified fraud its hog’s lined up at the feeding trough feeding on the ‘science on demand’ brought up by Lindzen in his essay ignoring any personal skepticism or self assessment as a true expert simply doing what they get paid to do.
Nick Stokes says
“The US has a population, and it isnt going to go away. NOAA, and others who measure the temperature, are trying to measure what it actually is, population and all.”
I think you make a great point Nick and makes this(Spencer’s)type of research even more valuable. Most of the disagreements on AGW center on natural cycles vs. the man-made component of temperature change. However, I don’t hear much on urbanization vs. CO2 impacts on the instrument record. It is mostly a CO2 discussion.
From a philosophical perspective, if increasing Earths measured average temperature is bad, would we not want to know the various components of that increase to make informed decisions. i.e. if it is strictly natural cycles, how can man interfere to control average temperature, seed the atmosphere with a reflecting agent? if it is urbanization do we spend trillions to add trees to our cities? And if it is CO2, do we forgo fossil fuels sooner than existing supply would have allowed increasing energy cost at a faster rate?
Of course there is always going to be the question of who decides what the best average temperature is and even if using an average makes any sense given regional differences. Anyway, thought is was a great comment.
“However, I don’t hear much on urbanization vs. CO2 impacts on the instrument record. It is mostly a CO2 discussion.”
The urban heat island effect has been studied for more than 50 years…
https://agwobserver.wordpress.com/2009/12/27/papers-on-urban-heat-island/
…and examined in all IPCC reports from the first in 1990 to the most recent in 2013.
“if increasing Earths measured average temperature is bad, would we not want to know the various components of that increase to make informed decisions”
That’s what the IPCC (and the research it relies on) has been doing for 30 years.
Complete nonsense from barry
A question was asked by Billy Bob:

Barry answered:
“Thats what the IPCC (and the research it relies on) has been doing for 30 years.”
COMPLETE NONSENSE !
The IPCC has been trying to blame global warming on humans since 1988, while claiming natural causes of climate change, which had caused ALL climate change for 4.5 billion years, are just “noise”.
The explanation for this alleged change, from natural causes of climate change, to man made climate change, is never proven — it is just assumed.
100 percent of the warming in the 20th century COULD have had only natural causes.
Claiming the warming in the 20th century is unprecedented, and could only have man made causes, is science fraud — your favorite kind of “science”, Barry !
“The explanation for this alleged change, from natural causes of climate change, to man made climate change, is never proven it is just assumed.”
This is pure bullshit, Richard.
“Claiming the warming in the 20th century is unprecedented….”
IPCC doesn’t claim that. IPCC points out that there were periods in the past that were warmer. Don’t fabricate, Richard.
“…and could only have man made causes…”
IPCC says warming in the early part of the 20th century was partly due to natural causes.
Why do you fabricate?
Unlike you, nasty Barry, I read — you fabricate!
I have read the IPCC Summary for Policymakers, even though the final draft is written by leftist politicians and leftist activists who are biased, believing that CO2 is the devil ion the sky.

A.1 Human activities are estimated to have caused approximately 1.0C of global warming above pre-industrial levels, with a likely range of 0.8C to 1.2C. Global warming is likely to reach 1.5C between 2030 and 2052 if it continues to increase at the current rate.”
It seems to me that first sentence implies humans are the cause of global warming since the (not specified) “pre-industrial levels”. and will be the cause of future warming
What warming is being attributed to natural causes in that VERY IMPORTANT first sentence of the IPCC Report?
Barry, you have a convenient memory. “Unprecedented rate of warming” is often used by Bill Nye the Science Guy.
I didn’t see Bill Nye’s name on the IPCC contributor list. Maybe I just missed it?
I see that Barry also becomes a ‘nasty’ person for pointing out the obvious flaws in RGs claims.
Richard, “with a likely range of 0.8C to 1.2C.” clearly allows room for part of the warming to be natural.
Various papers (eg Hansen 81) explained the temperature record in terms of a combination of natural (sun, volcanoes), and more recently (ENSO, ocean cycles) and anthro (CO2, aerosols).
When Bill Nye goes on CNN and MSNBC and spouts these idiotic claims, I don’t see you or anyone of your ilk or anyone on IPCC publically stating, “Bill doesn’t speak for us.” All we hear is crickets from the so-called 97%.
Cancel culture at work here? Bill Nye can express any opinion he wants.
Just as anybody can write what they want in denialist blogs.
Bill Nye does not speak for me.
The IPCC back up reports are released months after the Summary for Policymakers, for good propaganda reasons.
After people are told the conclusions in the Summary, they have no opportunity to look up the details to see if the conclusions exaggerate, omit uncertainties, omit assumptions, etc.
It also does not matter what the IPCC said in the 1980s or early 1990s.
It does matter what they say NOW, and natural causes of climate change are not featured in the Summary for Policymakers.
If you want to go far back in time, when the IPCC was almost an honest organization, rather than a leftist propaganda machine … they provided wisdom about climate science that seems completely missing from recent Summaries for Policymakers:
“14.2.2
Predictability in
a Chaotic System”
The climate system is particularly challenging since it is known that components in the system are inherently chaotic; there are feedbacks that could potentially switch sign, and there are central processes that affect the system in a complicated, non-linear manner.
These complex, chaotic, non-linear dynamics are an inherent aspect of the climate system.
As the IPCC WGI Second Assessment Report (IPCC, 1996) (hereafter SAR) has previously noted, future unexpected,
large and rapid climate system changes (as have occurred in the past) are, by their nature, difficult to predict.
This implies that future climate changes may also involve surprises.
In particular, these arise from the non-linear, chaotic nature of the climate system
… Progress can be made by investigating non-linear processes and sub-components of the climatic system.
These thoughts are expanded upon in this report: Reducing uncertainty in climate projections also requires a better
understanding of these non-linear processes which give rise to thresholds that are present in the climate system.
Observations, palaeoclimatic data, and models suggest that such thresholds exist and that transitions have occurred in the past.
… Comprehensive climate models in conjunction with sustained observational systems, both in situ and remote,
are the only tool to decide whether the evolving climate system is approaching such thresholds.
Our knowledge about the processes, and feedback mechanisms determining them, must be significantly improved in order to extract early signs of such changes from model simulations and observations. (See Chapter 7, Section 7.7).
14.2.2.1
Initialization and
flux adjustments
” … Models, by definition, are reduced descriptions of reality and hence incomplete and with error.
Missing pieces and small errors can pose difficulties when models of sub-systems such as the ocean and the atmosphere
are coupled.
As noted in Chapter 8, Section 8.4.2, at the time of the SAR, most coupled models had difficulty in reproducing a stable climate with current atmospheric concentrations of greenhouse gases, and therefore non-physical flux adjustment terms were added.”
In plain English — the climate models are “all fluxed up”.
Richard,
“I have read the IPCC Summary for Policymakers… Here is a quote from the BEGINNING of the 2019 version:”
That’s a Special Report that IPCC does in between the larger reports, not the IPCC state-of-the-science report on climate change that comes out every 6 to 8 years.
Special Reports have a narrow focus, and this one was about mitigation pathways.
In every IPCC assessment report, there is plenty of attention given to other causes of long and short term global temperature change (and sea level and precipitation change), and what their contribution might be on various time scales. Attribution studies are a key element in understanding what drives short and long term changes.
The chapters on observations, radiative forcing and attribution detail how natural influences are assessed against the trmperature record. Every SPM mentions the assessment of natural forcing and variability.
1990 First Assessment Report (FAR) Summary for Policymakers:
“What factors determine global climate?
What natural factors are important?
How do we know that the natural greenhouse effect is real?
How might human activities change global climate?
1995 SAR Summary for Policymakers:
“Any human-induced effect on climate will be superimposed on the background “noise” of natural climate variability, which results both from internal fluctuations and from external causes such as solar vaiiability or volcanic eruptions. Detection and attribution studies attempt to distinguish between anthropogenic and natural influences.”
2001 TAR Summary for Policymakers
“Changes in climate occur as a result of both internal variability within the climate system and external factors (both natural and anthropogenic). The influence of external factors on climate can be broadly compared using the concept of radiative forcing. A positive radiative forcing, such as that produced by increasing concentrations of greenhouse gases, tends to warm the surface. A negative radiative forcing, which can arise from an increase in some types of aerosols (microscopic airborne particles) tends to cool the surface. Natural factors, such as changes in solar output or explosive volcanic activity, can also cause radiative forcing. Characterisation of these climate forcing agents and their changes over time (see Figure 2) is required to understand past climate changes in the context of natural variations and to project what climate changes could lie ahead. Figure 3 shows current estimates of the radiative forcing due to increased concentrations of atmospheric constituents and other mechanisms.”
2007 AR4 Summary for Policy Makers:
“Changes in the atmospheric abundance of greenhouse gases and aerosols, in solar radiation and in land surface properties alter the energy balance of the climate system. These changes are expressed in terms of radiative forcing, which is used to compare how a range of human and natural factors drive warming or cooling influences on global climate. Since the TAR, new observations and related modelling of greenhouse gases, solar activity, land surface properties and some aspects of aerosols have led to improvements in the quantitative estimates of radiative forcing.”
2015 AR5 Summary for Policymakers:
“C. Drivers of Climate Change
Natural and anthropogenic substances and processes that alter the Earth’s energy budget are drivers of climate change.”
Richard G: The explanation for this alleged change, from natural causes of climate change, to man made climate change, is never proven — it is just assumed.
1990 FAR concluded it was not yet possible to detect a anthropogenic signal emerging from the envelope of natural variability.
1995 SAR concluded that although natural variability was still able to explain global temperature change, “Nevertheless, the balance of evidence suggests that there is a discernible human
influence on global climate.”
2001 TAR concluded “In the light of new evidence and taking into account the remaining uncertainties, most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations”
Confidence in detecting a human signal arising out of natural variability firmed up over time. It was never a given that natural influences are nil. The IPCC has always assessed the impact of all factors that could reasonably have an impact on climate.
Richard Greene: “The explanation for this alleged change, from natural causes of climate change, to man made climate change, is never proven — it is just assumed.”
If you mean, as I thought you did, that the IPCC simply assumes that carbon dioxide is the dominating factor in recent climate change without bothering to weigh the evidence for natural factors, then your statement, as I said, is bullshit.
The IPCC reports are freely accessible. Type in the 4 letters, go to the wbesite, do a bit of very elementary research. It’s all indexed. Educate yourself.
I was really referring to the discussion on this blog. Over the years, this blog mostly has centered on added CO2 GHE vs. natural variation. There is tons of research on UHI, and some of it older than 30 years. I remember studying it at Rutgers in the 80’s and it wasn’t new then either.
Thanks for the link though Barry, will take a look to see if there is anything interesting that I may have missed.
Urban areas are something like 1% to 2% of our planet’s surface.
So UHI warming in or near urban areas, over time, should be small.
But more than 1% to 2% of land weather stations are in urban areas.
So the first question is why?
People put weather stations where they live.
Figure 1 shows an very interesting statistic.
The fat part of the uhi effect is around 625 persons per sqkm.
That works out to only about 2 1/2 persons per acre.
Typical suburban development puts about 4 to 10 houses per acre with an occupancy of an average of about 2.7 persons per household. This ratio includes about 50% space for schools, small retail, parks, and roads.
One of the problems I noted with the Berkeley Earth examination of UHI is they were doing comparisons within the urban zone, specifically to dense urban to less dense urban.
It must have been designed out of ignorance about where the UHI bubble actually exists. . . .which just goes to show one good experiment is worth more than all the bad ones.
The defined urban areas in the US increased by 47% between 1974 and 1997. I haven’t found a trend chart for after 1997.
When you get to the 4 units per acre figure (approx 6k sqft lots) your density per acre is 4 times the fat part of the curve 2400 persons per sqkm. At that point in time folks are spending the next 30 years growing trees around their homes.
Roy’s graph shows virtually no urban warming for the dense urban development at 10 homes per acre (8,000 persons per sqkm), here there is far less opportunity for tree gardens.
Before anybody jumps all over this, there is much to look at here. I find figure 1 tantalizing. When one rolls up a lot of information into so-called urban clusters which I haven’t really figured out from an acreage/development standpoint it may be that what needs to be looked at is the process of deforestation and land grooming that precedes the expansion of suburbia.
Berkeley Earth’s analysis was with sites they classified as “very-rural” which means no urban influence within 1 degree lat/lon per the MOD500 dataset. These “very-rural” subset of stations warmed more than the set of all stations.
https://static.berkeleyearth.org/papers/UHI-GIGS-1-104.pdf
The MOD500 dataset is highly developed urban comprising .5% of the land. Using the GRUMP urban dataset you get 2.5% of the land.
Thats what is interesting about Figure 1 the most warming is occurring in the bottom .5% of urban land and there is essentially no UHI in the upper .5% (in terms of trends vs actual absolute UHI).
So to find the interesting stuff you need to increase your focus.
https://smap.jpl.nasa.gov/system/internal_resources/details/original/288_046_urban_area_v1.1.pdf
Note Section 2.4
Now that is the type of contribution to this blog I can absolutely accept. Berkeley Earth should redo their analysis with GRUMP and see what changes.
What I would like to hear is why Roy’s proposition of using hourly station data as opposed to relying upon uncertain time-of-observation adjustments in the USHCN dataset.
I have heard many weather experts say that that process of time of day adjustments treat station managers like programmed robots in it is assumed the time of the Tmax and Tmin is a certain time versus the time the station manager recorded it.
It is that kind of data fiddling that increases skepticism. And to be clear I am not alleging fraud, such outcomes can result simply due to the presence is some more rapidly warming stations coupled with a strong belief the warming arises from an identified source other than UHI.
That has been essentially the same approach with ARGO where ocean temperatures simply must be globally increasing due to sealevel rise from everything from ice melt to continental uplift. Those may be reasonable assumptions but reasonable assumptions go awry pretty randomly.
“That has been essentially the same approach with ARGO where ocean temperatures simply must be globally increasing due to sealevel rise”
I didn’t understand your comment here. ARGO measures temps by measuring temps, not by extrapolating from sea level rise. Sea level rise is alluded to as corroborating evidence of increasing ocean heat content.
Barry, ARGO adjustments arose in 2009 when it was discovered the ocean was cooling. Methodology involved comparing data to sealevel rise, models, and estimates of SSTs from other methods. When done NOAA reversed its viewpoint solely on the need for being consistent with other means of estimates that the ocean was warming.
Adjustment method was to toss out buoys suspected of leaking without confirmation.
Originally there was going to be a study on these buoys which never emerged, thus its reasonable to say the adjustment process continues in the absence of such a study.
Are there leaking buoys? Most likely yes.
Does such leaking to the extent it occurs reduce ocean warming. Yes.
Does it make sense to have a program that identifies leaking buoys? Yes
Has such a program been implemented? To my knowledge not to the extent of actually verifying the buoys that are leaking.
Like in any true scientific endeavor the question arises what we are actually using to determine rate of climate change in the ocean. The question should be transparently answered and available. If its a case that due to may lack of access to information my view is outdated a simple reference could put my mind at ease.
“ARGO adjustments arose in 2009 when it was discovered the ocean was cooling.”
The usual conspiracist BS from Bill.
There is no evidence of adjustments made by them because the ocean was cooling.
Aha Nate right on cue ready willing and able, as usual, to both demonstrate his ignorance and make a statement certain about which he knows nothing about.
Here is about version 6 of how adjustments were made to the ARGO system. By now in view of lawsuits launched by manufacturers of the probes discussion of leaks in the buoys had been edited out of the original document.
https://earthobservatory.nasa.gov/features/OceanCooling/page1.php
“made by them because the ocean was cooling.”
Technical problems yes. No surprise there. Corrections made yes.
Because of cooling, no. Bill BS.
Did I claim the ocean was cooling Nate? Nope I didn’t.
I am just interested in science investigating the matter.
According to the article and quite a few other versions leading up to the last one – technical correction was applied unscientifically.
Having a confab and picking a favorite isn’t science Nate. . . .in fact its not even technical.
“technical correction was applied unscientifically.”
Don’t see that. Are you making that up?
There is nothing scientific about confabs.
Errata…1 degree lat/lon should have been 0.1 degree lat/lon.
WUWT had an article on this around the time the Berkeley Earth paper was released with aerial photos (may have been Boston area) of zones defined as rural in the same aerial photo with the urban. So .1 degrees would be something around 6 miles versus 60 where it would be difficult to see the actual development.
I guess the bottom line roughly suggested by Figure 1 is on a density basis MOD500 grids and rural grids have something in common, namely no population trend. Who would have thought?
An alternative analysis of U.S. temperature trends from a mostly independent dataset from airports suggests that the U.S. UHI-adjusted average warming trend (+0.13 deg. C/decade) might be only 50% of the official USHCN station-average trend (+0.26 deg. C/decade).
The official USHCN trend is highly altered and has the airport data been adjusted for aircraft exhaust emissions impact.
Raw data from 1895 to the present graphed by realclimatescience.com does not reveal a warming trend.
https://realclimatescience.com/2021/02/coldest-valentines-day-on-record-2/ (graphs 5:15 mark)
You cannot use the raw USHCN data to deduce temperature trends due to TOB bias, instrumentation bias, station move bias, urban heat island bias, etc.
Climategate revealed the data altering was premeditated and was designed to disinform.
Dr. Spencer’s paper is meant to provide support to a highly altered USHCN data set and inaccurate projection.
I just lost all respect for him.
NASA and NOAA are producing not but propaganda.
Skeptics who have done the work confirm the need for adjustment to the US temp data.
Anthony Watts collaborated on a paper published in 2011 where they tried hard to avoid, but eventually had to concede, that time of observation bias was something they’d have to deal with or they would get spurious results. Once they’d done the work themselves, they realized that adjustments are necessary, and acknowledged that in the opening of thir paper.
https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2010JD015146
Cleaning up the data for climate purposes – to assess change over time – is an unfortunate necessity. ‘Climategate’ also revealed researchers trying hard to get it right.
ClimateGate revealed smarmy government bureaucrats with science degrees conspiring to change data they did not like, and to pressure publishers to not publish articles and studies that disagreed with the THEIR consensus (and their climate models, which are just their personal opinions programmed into a computer).
Anyone who claims ClimateGate emails were good news, or revealed honest science, is a l i a r … or a f o o l.
“was infilled by government bureaucrats”
Bureacrats? You mean researchers paid by govt grants or work for govt agencies?
Funny that this pejorative term keeps getting lobbed, since Roy Spencer and his colllaborators are just as much government bureaucrats as any of the accused.
‘Govt bureaucrats’ produce most of our meteorological data, I suspect.
Oh well.
No he isn’t talking about the data collectors he is talking about bureaucrats that substitute politically correct data for raw data.
Give us a couple of names of these bureaucrats.
thats the problem Barry. No audit trail.
Duh! The lack of evidence is proof of the conspiracy.
conspiracy is your word Nate.
Fact is people tend to find what they are looking for and not notice what they aren’t looking for.
Awareness of the above is the first job of an auditor in making decisions about dedicating resources to an audit. Lack of an audit trail makes tracking that down extremely difficult.
You wanted names. The lack of names should be your first concern, folks who handwave that away are those upon who suspicion falls the most quickly. . . .as witnessed by probably every mystery story written. . . .so even non-auditors should be able to pick up on the problem.
“that substitute politically correct data for raw data.”
Seems no evidence is required for you to believe in this.
I dont think people are subjectively picking data. Algorithms are used.
Are the algorithms bad?
Nate its not about algorithms being good or bad. All that is debatable.
Its about algorithms are not being observations.
bill,
Even something as trivial as a single temperature reading from a thermocouple requires a model and algorithm to map material properties and electrical voltages to meaningful temperature values.
And the amount of modeling and algorithms UAH employs to measure the global mean temperature is orders of magnitude above and beyond that.
If UAH or even a single temperature reading from a thermocouple, RTD, or laser interferometer is not considered an observation then what is?
“thats the problem Barry. No audit trail.”
The problem is that people like you and Richard say stuff that has zero substance to it.
Perhaps it is a problem with the way you guys think. If there is no data, you can’t make a claim. I don’t know how to explain that in such a way as to change your mind, but hopefully you’ll think about it for a while and see the logic for yourself.
bill,

—————————–
Obviously the mapping of material properties and electrical voltages is ones that are well known, universal and consistent. The day be day manual compilations of temperature data has a human element in it that isn’t well known.
As I understand it the one item UAH does that has some uncertainty is calculating satellite drift. Fact is because of moving cloud cover surface readings vary greatly hour by hour. We have seen this in Roy’s own backyard experiments and is consistent with my monitoring of personal weather station equipment over many years. If humans robotically measured the equipment in a consistent way and disregarded everything else there would be less to worry about. But human monitors are driven to compensate in a non-robotic manner. And when you have robotic monitoring. . . .Roy is right hour by hour data is far superior and with robotic monitoring hourly data is easy to obtain.
The experts that criticize adjustments on human monitoring characterize the problem as treating station managers like they were idiots, but the truth is nothing could be further from the truth.
barry says:
”The problem is that people like you and Richard say stuff that has zero substance to it.”
Zero substance? You are very welcome to show the audit trail to me. How can I show you something of substance if it either doesn’t exist or can’t be found?
I have spend the majority of my adult life professionally holding segments of the State and Federal governments to account. You operate as an ignorant man believing in black and white when in fact all is shades of grey. The only way in domestic government is complete transparency and full documentation. Without that people can never be free. And believe it or not the only reason its not complete and transparent is a combination of fraud, deceit, and tradition.
Tradition is listed because it is not an easy process of revealing the facts and that process must be built brick by brick with a lot of less than honest people trying to knock it down.
“You are very welcome to show the audit trail to me”
I asked Richard to name the “government bureaucrats” he claims infilled temperature data.
My point is that if there is no audit trail, then Richard’s claim has no substance. He can’t name names without the audit trail.
So please, direct your question to Richard, and maybe we will point out the audit trail.
Dr. Roy, great work as usual. I’m up over 260 Stations that show no warming uptrend.
https://wattsupwiththat.com/2021/02/12/urban-heat-island-effects-on-u-s-temperature-trends-1973-2020-ushcn-vs-hourly-weather-stations/#comment-3181833
One thing you may want to consider is not only controlling for the UHI Effect but also Water Vapor. Identify all the Desert Locations and you will discover that CO2 has no no impact on temperatures at all. Once again, here is a list of 260+ Stations that show no warming.
https://wattsupwiththat.com/2021/02/12/urban-heat-island-effects-on-u-s-temperature-trends-1973-2020-ushcn-vs-hourly-weather-stations/#comment-3181833
This is my favorite:
Alice Springs (23.8S, 133.88E) ID:501943260000
https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v3.cgi?id=501943260000&dt=1&ds=5
Of course, be sure to use the “Un-Adjusted” Data.
Lastly, NASA distorts the data. My bet is if you just look at the High Temperatures, you won’t find much warming in any location. The problem you face is accounting for the “adjustments” and accounting for the accuracy of the data in the first place. Another interesting study would be the spread between the High and the Low. My bet is that the spread won’t be narrowing, and if it isn’t, the average temperature will be approaching the High Temperatures of the day, which doesn’t make any sense.
CO2isLife said: Of course, be sure to use the Un-Adjusted Data.
What possible justification can you present that would convince us to prefer a time series with known errors and biases over one that has those errors and biases considered?
“I’m up over 260 Stations that show no warming uptrend.”
But we have checked some of those stations and found they do have warming trends. Apparently you do not have a method for assessing whether there are upward trends or not. You just look at the chart and make a declaration.
Your diligence is admirable, but it is wasted if you don’t apply rigour.
You checked? Really? What were the results? A teensy weensy warming trend? Is that true across the board or did you as you say just check a couple you wanted to check?
Your diligence is admirable, but it is wasted if you dont apply rigour.
bill the hunter said:
“What were the results?
A teensy weensy warming trend?”
I personally see an itsy bitsy warming trend,
not a tenesy weensy warming trend.
Itsy bitsy is real science.
Tennsy weensy is junk science.
‘Itsy bitsy is real science.’
Yep! But nothing to get your panties in a bunch.
Vilnius from 1960 is +0.420C/decade +/- 0.064. That is 3x the UAH TLT trend of +0.14C/decade.
You are, of course, encouraged to double check this value.
https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=LH000026730&ds=14&dt=1
bdgwx is that one of the 260 stations?
Yes
Interesting that no significant warming occurred until they hooked up with the Nordic and Euro banking systems in the mid naughts.
Interesting that your name has no capitalisation. Interesting and… suspicious.
we are talking about UHI barry.
Money has a way of attracting development, development is what attracts farmers to the city.
Rhetoric has a way of attracting BS.
There is nothing substantive in what you’ve just said. Just propagandistic waffle.
Barry waves his hand it the air and proclaims UHI as bogus.
The results are upthread. Statistically significant warming.
I chose some at random, so did others.
We didn’t need to check all 260. It was already obvious that the claim was deeply flawed.
CO2isLife needs to apply some test to the data before he calls any kind of trend. This obviously had not been done.
Nate: ”Maybe half, maybe 0”
Yes keep in mind we have 1) natural variation; 2) anthropogenic fossil fuel burning; 3) Deforestation and landuse change; 4) UHI
So Roy’s hourly station data suggests 1/2 due to UHI.
But thats only for the most aggressive surface records. UHI most likely isn’t an important factor in satellite data.
So one can conclude that 1 and 2 and perhaps 3 are factors in the observed warming recorded by satellites.
All you sycophants have been worshipping Berkeley Earth but . . . .why?
We are in interglacial period.
Past interglacial periods were much warmer than other present global average temperature.
It seems to me there 3 options:
1] We have already had the warmest part of interglacial period.
2} we going to have warmer part of interglacial period in the future.
3] Our interglacial period is somehow different than past interglacial periods.
And fourth option, my odd hybrid, our interglacial period was different and we already had the warmest part of our interglacial period, but maybe it will warm up again.
But it seems to me the Little Ice Age was likely the coldest time in last 10,000 years, and our warming is like all other warming periods that are following cooler periods over the last several thousands years.
“All you sycophants have been worshipping Berkeley Earth but… why?”
Why do you fabricate?
I like Berkeley Earth because it’s like The Hitchhiker Guide, slightly cheaper and easier to use.
If there better ref which gave average temperature of all countries
on Earth- and was cheap and easy to use- I might use it.
I agree. Nearly all the science being produced is useful. The trick is in determining usefulness for what purpose.
Fact is we live in a cold world. Hardly anybody beating the drum for a cooling world. . . .which would be something I might worry about.
I have had the advantage of having lived in multiple climates for long enough periods of time to adjust to them. Still just about everywhere you live there is enough natural weather variation to make you both to feel both too hot and too cold. Hawaii might be the only exception in the US being heavily buffered by the Pacific Ocean. Hawaii’s highest recorded temperature is 100F tying Alaska. Hawaii’s lowest recorded temperature is 12F, 14 degrees warmer than second place Florida. Most of us survive in a world with greater than 44C swing in weather temps and we fret about a 100 year extrapolation of 3C which looks to be from observations about 1/2 of that. Climate change is really only something folks worry about who have nothing else to worry about and like any war there will be big winners and big losers. With so much money at stake you really want to be sure you aren’t being conned about something to worry about for which there is no justification.
“So Roys hourly station data suggests 1/2 due to UHI.”
Sure if you apply no proper skepticism.
A real skeptic would look at this analysis and understand that it is very weak.
I can agree it can use more work and Roy recognizes that. But when it comes to weak. . . .its not even close to how weak your criticism is.
This work is deeply flawed
Hilarious..
By Feb. 17, the stratospheric intrusion will extend westward. I predict record low temperatures in the Rocky Mountains.

Dr. Spencer consider doing this research:
1) Identify locations protected from the UHI and Water Vapor Effect (Dry and Cold Deserts).
2) Have High Temps from UnAdjusted Data been increasing?
3) Has the Spread between High and Low Temps been narrowing, meaning that CO2 actually holds heat in the atmosphere over time
4) Have the low temperatures been increasing? If they haven’t, the AGW is moot given that warming is isolated to daily events and not changing over time as CO2 increases.
5) Run regressions based on ΔW/M^2 and temperatures, not ΔCO2 and Temperature.
6) Provide an explanation as to why so many stations show no warming trend, and an explanation as to why so many stations have a jump in temperatures over the last decade or so, but not over the previous 110 years.
Here are 265 Stations and links that show no warming. How is that possible? Do the laws of Physics Cease to Exist in those Locations. No they don’t. If Climate Science wants to be considered a real science and gain respect, that question needs to be answered.
https://wattsupwiththat.com/2021/02/12/urban-heat-island-effects-on-u-s-temperature-trends-1973-2020-ushcn-vs-hourly-weather-stations/#comment-3181833
Dr. Spencer, one other piece of research that would be great is to Validate what Tony Heller did by showing that the NASA Adjustments are almost universally biased towards warming. Cooling the distant measures and warming the near term measures. Also run a regression of the CO2 vs. the “adjustments.” If you get a high R-Square, that proves my point that the “adjustments” are intended to improve the relationship between CO2 and Temp in a more linear manner, but that is contrary to the real relationship of ΔW/M^2, not ΔCO2.
If you do that study, demonstrate the increase in linear trend in temperatures to match the CO2 trend. That is not consistent with the Physics. That is how you demonstrate motive and fraud. Data in intentionally being “adjusted” to improve linear models that are modeling a non-linear relationship. That is the problem Climate Science faces.
Here is another critical evaluation of the USHCN data set supporting Dr. Spencer’s conclusion.
If the corrections fixed known problems in the instruments, that would help accuracy. But they are statistical. They make the station measurements smoother when mapped and they smooth over discontinuities. In my opinion, NOAA has overdone it. TOB, PHA, infilling and gridding are overkill. This is easily seen in Figure 7 and by comparing Figure 3 to Figure 6 or Figure 5. Does the final trend in Figure 3 more closely resemble the measurements (Figure 6) or the net corrections in Figure 5? The century slope of the data is 0.25°, the corrections add 0.35° to this and the “climatological gridding algorithm” adds 0.9°! It is worth saying again, the type of statistical operations we are discussing do nothing to improve the accuracy of the National Temperature Index, and they probably reduce it.

At first I thought you wrote that paragraph, but you didn’t. That is from the article. You should put quotes around it.
The article describes some of the processing of data that goes on and the reason for it.
Then it does an abrupt left turn from being factual, and the author tells us they have a gut feeling that the processing goes too far.
Doesn’t do any analysis of their own to test their gut feeling.
But at least WUWT has moved on from decrying adjustments as needless and malign. No, in this article at least, the author understands that they are necessary.
Until some other article in the near future calls any adjustment a fudge.
Barry adjustments are a fudge.
Adjustments arise out imperfections in the collection system. Many years ago it was acknowledged that the absolute temperature of the climate might be off by as much as 2c and anomalies were used instead in order to detect trends from whatever the actual average temperature is.
Adjustments are made to supposedly provide consistency of potential absolute temperature whatever it is even if it is not actually representative of the overall climate. But at every single adjustment point uncertainty is introduced is the new station or new observation method actually affecting the consistency? Or have station managers actually done the ground truthing to ascertain there has been no affect.
This is an area of science concern. Science is supposed to be more concerned about consistency than perhaps a bureaucrat assigned to collect a temperature reading every day.
But a lot of people love their jobs and go far beyond simply being a robot and have their own curiosities. this isn’t factored in at some desk in Boulder Colorado where the station temperatures of Fargo North Dakota are changed.
So what does our Boulder Colorado scientist use as a benchmark. We have seen what it is over and over again. Its a combination of sources of information that comes from models, nearby stations, general system changes, etc. Each adjustment contains an element of a fudge arising from the individuals own biases.
Can we account for that? Yeah about as well as the Boulder Colorado scientist accounted for the actions of the Fargo, North Dakota station managers actions. In fact we can probably account correctly for the direction of bias of every single regular poster in this forum if they were to do the adjustment. We just won’t know the absolute value of the bias.
Bottom line is you want a monitoring system you don’t have to adjust. You want satellites with drift correcting abilities. You want weather stations built with equipment that doesn’t change and environments that doesn’t change. But above all you really need to know how climate varies. Setting up good laboratory experiments can be quite difficult. Setting up experiments in nature is mostly beyond what we can do.
Mankind struggles with developing ideal habitats on a small scale. We are far better off learning how to adapt to natural change. The world has been doing that for 4 billion years. We might ought consider jumping on that train rather than trying to stop the clock. Nature Deficit Disorder is a real psychological disease that is rapidly arising in our increasingly regimented society.
“Many years ago it was acknowledged that the absolute temperature of the climate might be off by as much as 2c and anomalies were used instead”
That’s not why anomalies are used. I think that is pure BS from you.
“Adjustments are made to supposedly provide consistency of potential absolute temperature whatever it is even if it is not actually representative of the overall climate.”
Could you please provide a methods paper where the stated goal is to adjust temperature data in order to “provide consistency of potential absolute temperature.” I think this is BS from you.
Who the hell is the Boulder scientist? If you dialled the rthetoric down in favour of facts and figures with references, the conversation might get interesting.
That is why ‘only’ anomalies are used. If the absolute mean surface temperature were 2c different 3watts of ghg forcing would produce for all intents and purposes the same anomaly (the difference would be immaterial).
What I find really hilarious is trying to limit global warming to 2 degrees from levels found in the Little Ice Age that ended 150 years ago. That might have been something my great great grandfather may have given some consideration to, like I might give some consideration to the idea of the climate warming another 2c from today. but since I actually celebrate the warming to date its hard to turn around and worry about it.
I strongly suspect that if it warms another degree in my lifetime that any additional concern about 2 more degrees above that will become more worrisome. Fact is global warming panic is totally lacking any baseline about which to worry.
So the propaganda focus is on the young who think they will live forever and the parents who worry about their kids even when there isn’t really anything to worry about.
No link to a methods paper, nothing to corroborate what you’ve said.
I think you make some stuff up, and the above is of that ilk.
Its automatically corroborated Barry. Check Stefan and Boltzman for the temperature difference for a .2deg anomaly at 15C and 18C
For a 3 degree C difference in absolute temperature a .2 deg anomaly at 18C is equivalent to about a .205 anomaly at 15C.
The rest is my viewpoint on what it means to warm 2degC from 1880 when there is allegedly already 1.5degC sunk. It means nothing to me.
Anomalies: another faux controversy to build a conspiracy theory around.
Nate says:
”Anomalies: another faux controversy to build a conspiracy theory around.”
Boy you sycophants sure can’t think for yourselves. I am building a controversy I am defending the use of anomalies. The only problem I have seen in the use of anomalies is actually not honoring the principle like in introducing computer generated historical polar data in order to claim some higher variability in the arctic.
That is a violation of the principle of consistency. Its fine to start monitoring polar data but mixing it with computerized rebuilds after the periods rebuilt were declared to contain inadequate data simply because it is now known that a good deal of atmospheric warming occurs when sea ice melts fails to consider where that heat is coming from and where it is going.
Hear, hear: Co2isLife calling ‘Dr Spencer, Dr Spencer! Here are over 260 GHCN stations showing no warming’ !
So what.
barry, bdgwx and I we repeatedly pleased CO2isLife to stop eye-balling on GISS station data graphs, and to start processing the stations’ data instead, in order to obtain a real picture of their trends.
For each station he collected, CO2isLife can
– download the data, e.g.
https://data.giss.nasa.gov/tmp/gistemp/STATIONS/tmp_NOM00001233_14_0_1/station.csv
– enter this data into a spreadsheet tool
– let it calculate the data’s trend, and
– build an average over all calculated trends.
That’s the right way, based on information instead of guessing and eye-balling.
I didn’t process any GHCN V4 data until now, and unfortunately, the same stations ids refer in many cases, within GHCN daily, to completely different station metadata.
Dombaas in Norway is the perfect example, see the GHCN daily data:
NOM00001233 62.0830 9.1170 638.0 DOMBAAS 01233
NOM00001233 62.0830 9.1170 TMAX 2006 2021
NOM00001233 62.0830 9.1170 TMIN 2006 2021
NOM00001233 62.0830 9.1170 TAVG 2006 2021
compared with GHCN V4:
Dombaas 62.0830N, 9.1170E NOM00001233 (BI) 18 01/1880 – 01/2021
Thus, an evaluation of the station data using GHCN daily unfortunately is not possible.
Maybe somebody can do the same job I usually do, but by using GHCN V4 instead.

– enter this data into a spreadsheet tool

Actually I did that, and you get a wave, and no trend. Temps increase in the early party of 1900, fall in the middle, and increase in the later part of the 1900s. There is no trend.
Using regression analysis, as I’ve explained a million times, isn’t appropriate for data that is this volatile and has an R^2 well below 50. CO2 causes warming. If temperatures in the last decade are below the levels set early in the 1900s, CO2 can’t be causing the warming even if the recent temperatures are at a peak. You have to tie the log decay in ΔW/M^2 to Temperatures, and CO2 can’t cause spikes. You rely on recent spikes to distort your regressions knowing full well that the recent spikes can’t be due to CO2.
CO2isLife
Until now, you didn’t explained more than trivial stuff, indeed a million times.
Don’t write so much, and manage to show you your results.
J.-P. D.
Bindidion, for the nteenth millionth time, that data you want me to download and run a regression on is “adjusted” data. The slope you are calculating is a slope of the “adjustment” over time, not temperature over time.
You honestly want to argue that there is an uptrend in this data just because you calculate a positive trend in the regression stats? That is absurd and pure fraud.

Oooops, I stand corrected. I just downloaded the data and it is the UnAdjusted” data. For some reason I thought the previous data I had downloaded was “adjusted” data. Anyway, when I run the regression I get these parameters.
0.0003 Slope
0.0008 R-Sqr
In other words, there is no relationship between CO2 and Temperature over the past 140 years.
Now try it with adj-cleaned data which fixes known errors and bias with the station’s time series. Report what find. Make sure to include the standard error on the trend. It is R2C1 in the matrix LINEST returns.
As I commented under the thread on WUWT, the warming trend is much less if you go back further in time. Since Roy’s trend is almost exactly the same as HadSST3, I brought HadSST3 back to 1940 to try and remove most of the effects of natural cycles and volcanoes.
https://www.woodfortrees.org/plot/hadsst3gl/from:1940/to/plot/hadsst3gl/from:1940/to/trend
As we can see the trend now drops to .07 C / decade. Certainly this is not any kind of climate emergency. Add in that ocean salinity changes probably account for most of this and we are left with CO2 having very little effect. That agrees with this recent paper.
https://www.scirp.org/journal/paperinformation.aspx?paperid=99608
After considering the paper I think I now understand why CO2 back radiation has such a small effect. It’s there. They measured it in this experiment. However, almost no warming.
The first thing a person needs to do is accept the result is valid. Once that is done the reason starts to unfold.
The back radiation does not warm the air because the GHE is essentially saturated. Hence, it goes all the way to the surface. However, the surface (the back wall in this case) has a heat capacity 1000+ times that of air hence will only warm a small amount. That won’t have much effect on the air in the time they ran the experiment.
If they let the experiment run for a long time they might start to see some effect. The problem is that source of the heat turns off on planet Earth in a pretty short time. The surface then cools and because of several mitigating factors almost all the heat is lost before the sun returns.
The combination of a nearly saturated GHE in the lower atmosphere and the huge difference in heat capacity between the surface and the air almost completely negates the ability for back radiation to warm the planet beyond where we are today.
I read above the typical statement:
” In my opinion, NOAA has overdone it. TOB, PHA, infilling and gridding are overkill. ”
I have read some comments posted here by ‘S.K. Dodsland’, and these comments are very probably based much more on guessing and pretending than on own evaluation of data.
Especially the gridding point is of interest.
In summer 2018, Roy Spencer published in a thread a graph made by John Christy:
https://www.drroyspencer.com/wp-content/uploads/US-extreme-high-temperatures-1895-2017-550×413.jpg
Prof. Christy’s idea was to collect, for each year, the number of daily maxima temperatures per station going over 100 F resp. 105 F.
Commenter Bily Bob soon asked for a corresponding graph concerning the whole Globe.
I thought: why not to do the job, and as USHCN is of course restricted to the US, I chose GHCN daily with about 40000 stations worldwide, and made a similar graph for CONUS:
(1) https://drive.google.com/file/d/1qGV5LfKw_lFKNdZMlq15ZHz6sA1CA294/view
Now I extended the range from CONUS up to the Globe, and was surprised to see
(2) https://drive.google.com/file/d/1GMuNs9ptRzDd7KxFQbKv0o5ySR5VNc9b/view
because it did not at all give any match to what I had experienced before.
The reason was that in graph (2), about 20000 US stations compete with about 20000 stations outside of CONUS.
Gridding (or ‘area weighting’) means to average the data provided by all stations encompassed by the same grid cell, and then to average the data of all grid cells into time units, e.g. months.
Thus an area weighting based on a UAH-like grid (2.5 degree) was used; this gave a very different view on the same worldwide data:
(3) https://drive.google.com/file/d/1TFdltVVFSyDLPM4ftZUCEl33GmjJnasT/view
Now you have, instead of 20000 US stations competing with 20000 other stations, about 200 US grids competing with 2200 worldwide, what corresponds much better to CONUS’ 6% of Globe’s land surface.
*
Who still pretends that gridding is something like data wrangling, as expressed by a commenter at WUWT, is simply dishonest.
*
Recently, Prof. Christy published a remake of his observation, now based on better ideas, without treshold values like 100/105 F, and including near TMAX a TMIN analysis.
The results when extending his scheme up to a global view remained very similar.
I’ll post these results when I have time to do it.
J.-P. D.
Just look at this Fraud:
1) Unadjusted data shows absolutely no warming over the past 120 years, in fact, 2010 is near an all time low. 1890 has a temp of 18.25, current Temp is 17.75. There is absolutely no up-trend. The “Adjusted” data shows warming from 14.75 to a peak of 19, and current Temps are at 17.75. 3 Degrees of warming that are 100% data manipulation. More importantly, the Temp Trend becomes more linear in a clear uptrend. Note how the adjusted data is below the actual, then matches the actual, then exceeds the actual. This is fraud if you put the “adjustment” in the context of someone trying to make a linear model produce better numbers. That is the motive for these “adjustments.”

Real Model ΔTemp = Log(ΔCO2) where Log(ΔCO2) = ΔW/M^2
That is the problem Climate Science Faces, they are trying to make a Log Function linear. They are trying to fit a square peg in a round hole. It will never work. Simply study the quantum physics of the CO2 molecule.
Bindidion Says: barry, bdgwx and I we repeatedly pleased CO2isLife to stop eye-balling on GISS station data graphs, and to start processing the stations’ data instead, in order to obtain a real picture of their trends.
Simply take a look at this Graphic. Clearly there is an uptrend in the “Adjusted” data and no trend in the “Unadjusted” data. Running a regression on the data that you can download, the “Adjusted” data will definitely give you a regression trend with a positive relationship between time and temperature. Problem is, that regression is a measurement of the adjustment over time, not temperature over time. It is classic GIGO. Only a fool would believe that there is an uptrend in the actual real temperature data, and only a fraud would try to pass off regression stats on the “adjusted” data.

BTW, if someone knows how to download the “Unadjusted” data please post it. I’m 100% confident that I’ll be able to show significant differences between the slopes of the unadjusted and “adjusted” data. What kind of science relies on “adjusted” data to support their conclusions? If the data needs to be “adjusted” to support your conclusion you are either 1) not measuring the data correctly or 2) you aren’t getting the results you want from the real data so you adjust the data to fit the model which is anti-science. Real science adjusts the model to explain the data. The data is the independent and dependent variables, the model defines the relationship.
Back on the station map you need to select the dataset before you search for the station. I believe you can also change the ds= parameter in the url. 15 is unadj, adj is 12, adj-cleaned is 13, and adj-homogenized is 14. The csv download button pull the data from the ds selected.
There has definitely been global warming since the coldest decade during the Maunder Minimum (1690s) … and it could be +2 degrees C. (climate proxies are not precise enough to make a better guess).
The global average temperature pre-World War II is based on questionable data.
Poor global coverage before 1920.
Horrible global coverage before 1900.
No one knows the global average temperature in 1890 to two decimal places, and probably not to one decimal place.
There were few land weather stations outside the US, Europe, the east coast of China, and the east coast of Australia, before 1900.
Sea temperatures were measured with buckets and thermometers at random locations, almost entirely in Northern Hemisphere shipping lanes. The result might be accurate to the nearest degree C., definitely not hundredths of a degree C. (Maybe +/- 0.5 degrees C. for the Northern Hemisphere only.)
There are two choices for the climate on our planet — warming or cooling. Most people prefer warming.
The anecdotal, climate reconstruction and real-time measurement evidence strongly suggests intermittent warming since the late 1600s.
Any claim of no global warming in the last 300 years, or the last 100 years, or in the last 50 years, is likely to be wrong.
Note: I could be biased. I love global warming, and want more!

Basically, there is no relationship between CO2 and Temperature over the past 140 years. Be careful what you wish for Bindidion, barry and bdgwx, you just might get it. Any fool can look at those charts and know there is no real trend in them.
“Basically, there is no relationship between CO2 and Temperature over the past 140 years.”
I disagree.
The correct statements in my opinion:
(1) There was no known CO2 temperature relationship for almost 4.5 billion years
(2) In the past 500,000 years, temperature peaks happened hundreds of years before CO2 peaks, per Antarctica ice core studies.
(3) Since the 1970s, there has been a relationship (positive correlation) between CO2 levels and the global average temperature. But correlation is not causation, so it is only an assumption on how much of the warming could be blamed on greenhouse gasses — I can say for sure the percentage is between 0 and 100%.
I can also say for sure the future climate will be warmer, unless it is cooler. I can also say with confidence that people generally prefer warming.
No one would even notice climate change if not for hysterical leftists bellowing “climate emergency”, so no one can enjoy the best climate on this planet, for humans, animals who live outside, and plants, in hundreds of years. It’s like having a sunny warm spring day where you live in Florida ruined by a miserable leftist neighbor who can’t stop talking about the coming hurricane season.

” Basically, there is no relationship between CO2 and Temperature over the past 140 years. ”
Your problem is that your trial to prove this is based on trivial stuff – of exactly the same niveau as what Moon spin deniers are able to give: ball-on-a-string, merry-go-round, coins and the like.
I have tried numerous times to explain to you that there is indeed NO relation between surface temperatures – regardless where they are measured – and CO2’s activity.
If this activity exists – what I can’t prove because I lack the scientific education to do that – then it is located ABOVE THE TROPOPAUSE, where water vapor disappears because it is a condensing gas and precipitates.
If I had any motivation or better: any reason to do, I would translate this document in English:

Bindidon one isn’t a moon spin denier simply because he isn’t a sycophant of an arbitrary assignment of spin energy. The spin energy of the moon exists both in terms of its bonds to earth and independently should those bonds be broken. What they aren’t is doubled. To put an independent spin on the moon or particles in the deck of a merry-go-round you must add energy.
What you have utterly failed to do is challenge Tesla’s calculations surrounding the matter and choose ‘group’ hand waving as your only argument. . . .just like you do with CO2.
hunter
As usual, you prefer Tesla’s oversimplified quick shot to the work of a well known astronomer like Tobias Mayer, who wrote a splendid treatise about Moon’s spin:
https://www.e-rara.ch/download/pdf/913790?name=IV%20Abhandlung%20%C3%BCber%20die%20Umw%C3%A4lzung%20des%20Monds%20um%20seine%20Axe%20und%20die%20scheinbare%20Beweg
You might lack the ability to read and understand the German text, written and typeset 270 years ago; though not being written in my native tongue, I had no problem to read and understand all 130 pages.
Btw, hunter, the group hand waving in fact is on YOUR side: people like you and your friends Roberson, ClintR, DREMT and some others would never and never be able to scientifically contradict what Mayer published in his treatise.
You wrote, not so long time ago that Mayer failed in keeping it simple or something similar: that tells me everything about your way to think about science… and engineering.
And boasting genius Robertson was even able to write ‘Mayer didn’t know what he was talking about’ !!! Ha ha ha haaah.

Why, do you think, did nobody translate Lagrange and Laplace’s 300 pages long treatises into English?

Steven Wepster wrote a book in English about Mayer’s work, unfortunately behind paywall:

But it is still far away from what I need: a perfect, 1-2-1 transcription of Mayer’s document that accurately reproduces how Mayer, starting from seemingly trivial observations at the telescope with the help of a self-made micrometer, finally comes through numerous trigonometric transformations to data that clearly demonstrate the rotation of the Moon.
J.-P. D.
What you have to do Bindidon is open up your mind.
Einstein came along and shook up classical mechanics with his relativity observations. Perspective is the basis of all classical mechanics.
You want to throw a bunch of classical mumbo jumbo out here from authors that far preceded Einstein. Fact is the disk of a merry-go-round accelerated by motors encompasses all the forces necessary to spin the disk. Same deal for orbiting celestial bodies. Fact is all objects in the universe have a spin in that they all rotate around something else influenced by gravity. Those objects not perceived to be orbiting are in fact orbiting. The concept of barycenter’s was created to deal with rotations that don’t go around the other influencing object.
Traumatic events like collisions are able to create additional rotations. Objects entering orbits speed up their apparent rotation without adding energy like an ice skater pulling in her arms.
Objects with different rates of spin to their orbits slowly do adjust to the rate of spin of the orbit. And that final piece is the final fact. You can’t have an orbit without angular momentum. Its complete BS that such an orbit where all sides of the orbiting body are seen from the COG of the orbit is an additional energy that eventually will be absorbed into a single perspective from the COG with an adjustment to the orbit.
So in a narrow minded classical sense its not difficult to attribute mathematically that momentum to an spin on an internal axis. Tesla did a credible job of translating his native Serbian to English, made his argument briefly in English. You on the other hand want to hide behind a text with no translation. You don’t want to debate you simply want to avoid debate.
…but not on its own axis.
As a follow up to the above:
1) Curvilinear translation is simply a translation plus angular momentum.
2) A curvilinear translation is a rotation around a single axis when all the particles are moving in concentric lines.
3) A curvilinear translation has two or more axes when all the particles are not moving in concentric lines.
I am not making this up just read Madhavi.
hunter
” You on the other hand want to hide behind a text with no translation. You dont want to debate you simply want to avoid debate. ”
As usual: claims about what I allegedly intend to do.
If I was able to find the text, I evidently would have provided for it.
But one thing I evidently won’t do: to translate all 130 pages of Mayer’s text by my own.
Two years ago, I translated Lagrange’s introductory text (about 10 pages) with the result that it was superficially and woefully discredited by the boasting Ignoramus Robertson who was not able to read more than the first lines of it.
Never again!
Keep free to discredit real science with Tesla’s quick shot, hunter! No problem for me.
J.-P. D.
Thats of course all BS Bindidon you haven’t even made a claim of particular calculations that shows the angular momentum of the moon spinning on its own axis isn’t identical to the angular momentum of any rotating object whether it be on its own axis or on an external axis. Its certainly not both.
And if its not both Madhavi correctly classifies it. And if its not both then your antique classical theories have nothing.
bill hunter nailed it: “bindidon you are well known to be impressed by anything that spins your political outlook.”
Bindidon is not able to fool thinking people anymore. He’s spent too much time here trying to pervert reality.

” … then your antique classical theories have nothing. ”
Whom do you mean here, hunter?
For example, Newton?
Apart from about 10% added by Einstein, Newton’s gravity theory still is present, zero dot zero percent ‘antique’.
And you reach here a maximum of perversity.
Dunno why, hunter?
Simply because you not only reject all these “antique classical theories” ! Oh no.
You also reject everything made by lots of people since the beginning of the 1960’s.
You wouldn’t even be able to understand what Steven Wepster wrote about Mayer’s calculation of Moon’s spin about its axis (lin above, see Chapter 9).
You reject EVERYTHING that does not fit into your little pseudo-knowledge.
A propos Madhavi:
Do you have an identifiable source of this person where he supports your idea that the Moon doesn’t rotate as calculated by Mayer and hundreds of other people after him?

Wepster was able to extract important information from Mayer’s works to further his works that are completely 100% non-dependent upon which axis the moon rotates around. But you are too utterly stupid to realize that.
Bindidion Says:
I have tried numerous times to explain to you that there is indeed NO relation between surface temperatures – regardless where they are measured – and CO2’s activity.
This entire frraud science is based upon that single concept. You can only tax carbon. CO2 has to be the basis for this socialist religion. Climate Change is Tabacco Lawsuit 2.0. Socialism is a parasitic non-sustainable system that is always seeking a new host. Energy is that new host.
Bindidion Says: If this activity exists – what I can’t prove because I lack the scientific education to do that – then it is located ABOVE THE TROPOPAUSE, where water vapor disappears because it is a condensing gas and precipitates.
Actually, it does, and the Stratosphere has been cooling, not warming. The GHG Effect is radiative, so its most effective action is to cool because it rapidly removes energy from the system.
Consequently, decreased ozone in the stratosphere results in lower temperatures. Observations show that over recent decades, the mid to upper stratosphere (from 30 to 50 km above the Earth’s surface) has cooled by 1° to 6° C (2° to 11° F). This stratospheric cooling has taken place at the same time that greenhouse gas amounts in the lower atmosphere (troposphere) have risen. The two phenomena may be linked.

Dr. Spencer, Bindidion, barry and bdgwx may have discovered a great research project for one of your Grad Students. They love to play games with a regression on a data set with a very low R-Sqr and a sudden non-CO2 caused spike in temperatures. If you remove the last decade of a 140 year track record, you get no warming in many if not most of the charts I’ve posted.
To adjust for this recent non-CO2 related spike that distorts the regression with outliers that can be misrepresented by people making a dishonest conclusion, basically lying with numbers to deceive those that don’t understand statistics and trend analysis.
The Project would simply be to start a ROLLING Regression, starting at the first main peak. Anchor the starting point, but float the end point and copy it down the data set.
What that will demonstrate is how the trend changes over time as new data is added. The purpose would be to identify how long a station exists with no warming, basically, identify the “Pauses.” Bindidion and others use station data that is flat for about 120 years, and then pops up for the final 20 years. Using a rolling regression you will be able to identify that for 120 out of 140 years there was no warming at this station. Clearly CO2 isn’t causing the warming.
Using this station as an example, the regression would start at 1931 and the rolling regression shows a (-)Slope until 1985, a 54 year period of no warming using regression analysis that Bindidion and the others seem to love. How does an increase in CO2 cause a 54 year pause in termperatures? In 2020 the slope is a laughable 0.003, or 0.03 Decade or 0.3 every 100 years IF THE TREND PERSISTS which it won’t. Simply put, Trends change over time, which wouldn’t happen if CO2 was the cause of the warming.
Indian Head Cda (50.5500N, 103.65W) ID:CA004013480
https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=CA004013480&dt=1&ds=15
NASA’s own data proves AGW is a fraud if people only understood how to understand and present the data in an easy to understand fashion.
To put things in perspective, the R-Sqrs of the station temp time analysis will show near 0.00, and the rolling slope described above is very volatile. Do that for CO2 data from Moana Loa and you get a near PERFECT 0.976995321. Perfect = 1.0.
The slope over the entire time period is 0.62 ppm/yr, but has been increasing.
CO2 has very solid numbers when linear regression stats are applied. Station data doesn’t. That is the problem CLimate Change Science facts. They are trying to fit a square peg in a round hole.
Correction, the Slope is 2.243437834 ppm/yr. I had an error in the formula thinking it was monthly data when it was formatted to be daily. That caused a big difference in the scale.
CO2isLife said: Using this station as an example, the regression would start at 1931 and the rolling regression shows a (-)Slope until 1985, a 54 year period of no warming using regression analysis that Bindidion and the others seem to love.
The trend for Indian Head Cda from 1931 to 1985 is -0.039C/decade +/- 0.102. Though not statistically significant it is indeed negative.
CO2isLife said: Trends change over time, which wouldnt happen if CO2 was the cause of the warming.
Clearly the hypothesis “CO2 is the only thing that can modulate temperature and will always result in a positive trend with R^2 = 1” is wrong. We just performed a falsification test. It was falsified.
bdgwx, what is your position on CO2 and Temperature? You make a big deal out of finding positive slopes in data sets with 0.00 as the R-Sqr. Every Station I posted will easily have multi-decade flat and negative slopes. It you simply remove the outliers in the recent decade, most will have (-) Slopes for most of the 1880 to 2000 period. Do you still claim CO2 is causing the warming, even though the slope is totally dependent upon the recent outliers.
My position is the same as the scientific consensus which is supported by the abundance of evidence.
CO2 is a significant contributing factor to the positive linear regression trend of the global mean temperature and oceanic heat content from 1850 to present but especially from 1960 to present.
and
Human emissions account for the vast majority of the 130 ppm rise from 280 ppm to 410 ppm.
Don’t hear what I didn’t say. I didn’t say that CO2 alone can explain all temperature movements on all spatial and temporal scales. I didn’t even say that it was sufficient to explain the entirety of the linear regression trend of the global mean temperature and oceanic heat content by itself. I repeat…the models that best match reality include ALL climate forcing factors including but not limited to solar radiation, clouds, land use changes, albedo, sea ice, land ice, orbital dynamics, biosphere changes, aerosols, greenhouse gases, etc.
4.5 billion years of huge climate changes from natural causes, yet the IPCC was already dismissing natural causes of climate change as “background noise” in 1995.
The bias toward blaming humans for climate change was obvious in the beginning of the IPCC (1988), and is worse now.
From 1995:
“1995 SAR Summary for Policymakers:
“Any human-induced effect on climate will be superimposed on the background “noise” of natural climate variability … “
Blaming humans was the only reason for the IPCC. Blame is like oxygen for the IPCC. Deprive it and it will wither and die.

More CO2 = more life on our planet.
Only a fool, or a leftist (I repeat myself) would believe CO2 is the “devil in the sky”.
We have all lived with global warming for 45 years.
The moderately warming climate has been wonderful.
The climate has not been better in our lifetime, and has been getting better since the 1970s.
We could enjoy it more if pesky leftists were not always bellowing about a coming climate crisis.
They started the warnings in the late 1950s, in a calm voice, but have been getting louder ever since.
They have now reached hysteria — DURING the best climate on our planet in over 300 years.
What’s wrong with those climate alarmists?
““Any human-induced effect on climate will be superimposed on the background “noise” of natural climate variability”
Fail to see any controversy in this statement.
But conspiracies are hidden everywhere…
Nat:
“Noise” implies ‘background noise’, and unimportant, which is exactly how the IPCC treats natural causes of climate change.
4.5 billion years of huge climate changes with no input from man made CO2 at all, and suddenly natural causes of climate change are demoted to “noise”.
That’s junk science, and you love it.
It doesn’t how CO2 (or any GHG) got into the atmosphere. It has the same effect.
We don’t have trustworthy climate proxy evidence to show the relationship of CO2 and temperature beyond about 500,000 years ago, using Antarctica ice cores.
It would make sense that what we have found out about natural climate change in the past 500,000 years also applied to the four billion years before that, but that is just an assumption.
What we have learned from ice cores is that temperatures peaked BEFORE CO2 levels peaked.
Strongly implying that temperature changes CAUSED CO2 changes, NOT the opposite.
The usual, sensible explanation is that natural causes of climate change warmed the oceans and as the oceans warmed they released dissolved CO2 in the atmosphere.
Just like a cold soda pop sitting outdoors on a hot day.
If the extra CO2 in the atmosphere caused a higher vapor content (Water vapor positive feedback theory beloved by climate alarmists), then there would be additional warming, releasing more CO2 from the oceans.
Eventually the runaway global warming (positive feedback) would have ended all life on our planet.
And none of us would be here today to give each other a hard time about climate change.
But runaway warming never happened.
Even with CO2 levels up to 10 times higher than today, according to geologists.
All prior warming trends ended, and cooling trends began.
So there is no evidence that CO2 levels ever controlled the temperature of our planet.
And ZERO evidence of a water vapor positive feedback tripling the claimed greenhouse effect of CO2 alone.
“What we have learned from ice cores is that temperatures peaked BEFORE CO2 levels peaked.
Strongly implying that temperature changes CAUSED CO2 changes, NOT the opposite.”
Not at all. It is well known that temperature rise can cause a CO2 rise.
But also we KNOW that we currently have a GHE: a CO2 rise can cause a temperature rise.
You see a chicken hatching out of an egg and conclude ‘Chickens DON”T cause eggs’
Brilliant.
RG said: We don’t have trustworthy climate proxy evidence to show the relationship of CO2 and temperature beyond about 500,000 years ago, using Antarctica ice cores.
Reasonably reliable proxies go back about 500-1000 million years in the past. We can certainly debate on how “reliable” they are though.
RG said: Strongly implying that temperature changes CAUSED CO2 changes, NOT the opposite.
Remember, CO2 both forces temperature changes and responds to temperature changes. Therefore it can both lead and lag the temperature depending on which set of agents catalyzed the temperature change. There are several episodes in Earth’s history in which sudden carbon releases catalyzed a temperature increase. The PETM is probably the best analog to our current era. And, of course, the CO2 forcing is required to explain to the faint young Sun problem.
RG said: The usual, sensible explanation is that natural causes of climate change warmed the oceans and as the oceans warmed they released dissolved CO2 in the atmosphere.
Except…carbon mass is increasing in the ocean today. The ocean is taking up the excess carbon in the atmosphere.
RG said: Eventually the runaway global warming (positive feedback) would have ended all life on our planet.
A runaway greenhouse effect is not possible on Earth.
RG said: Even with CO2 levels up to 10 times higher than today, according to geologists.
Yep. And remember that like all main sequence stars the Sun brightens as it ages. It is ~1% dimmer for every 120 million years in the past. That means even at 10x the current amount it still would not have provided enough radiative force to offset the -14 W/m^2 solar force 600 MYA.
RG said: All prior warming trends ended, and cooling trends began.
Yep. And they do so for a reason. We want to know what those reasons were.
RG said: So there is no evidence that CO2 levels ever controlled the temperature of our planet.
Patently False. There is a mountain of evidence. I think what you actually mean is that you just don’t accept the evidence.
Nate says:
”Not at all. It is well known that temperature rise can cause a CO2 rise.
But also we KNOW that we currently have a GHE: a CO2 rise can cause a temperature rise.”
————————
There is a degree of uncertainty in that statement Nate. Fact is climate involves far more than the radiating surface of the ground and ocean surface. We only know that that surface is affected by what it actually sees above it. We don’t know how its affected by that which is hiding behind what it sees.
“We don’t know how its affected by that which is hiding behind what it sees.”
‘We’?
Your ignorance of the science does not mean Science is ignorant.
Nate having an opinion means thinking you know something that you really might not.
The claim the science on all this solid is just balderdash.
Unlike USHCN which is deprecated since 2014 but still exists, GHCN V3 has been shut down in 2019.
Nonetheless, the data is alive and can be downloaded and evaluated by anybody who knows how to do.
As opposed to GHCN daily and GHCN V4, GHCN V3 has a nice feature: all 7280 stations (which all are real, regardless what boasting genius Robertson might pretend about them) have, in the station metadata file, some attributes specifying rurality and brightness index.
I made years ago comparisons between time series generated out
– ‘rural’ stations with the lowest of the 3 BI categories (about 2300);
– suburban and urban stations with highest BI (about 2900);
– all stations.
Here is the most recent output — for CONUS:
https://drive.google.com/file/d/1XvrhqhSkJl23pqqr70g6_fuSmHFlfLMX/view
I know: this distinction has become somewhat arbitrary over the years. But we have it, and to criticize it is quite simple.
What I found interesting is that
– while having bypassed the other plots around 1990, the ‘urban’ plot was way below the others decades ago, what explains its far higher trend;
and above all that
– the ‘all stations’ plot has been all the time much nearer to the ‘rural’ plot than to the ‘urban’ plot.
But the main discussion for me is – as Nick Stokes wrote – centered around the fact that we can’t ignore urban heat just because lots of alarmists try to misinterpret and misrepresent it as a consequence of solely CO2 increases.
This is the reason why I don’t understand Roy Spencer’s idea.
J.-P. D.
Most urbanization bias studies relied on just one indicator to separate urban and rural stations.
Peterson, 2003 assumed that a station was urban once the nightlight brightness in the area, measured by satellite,
reached a certain value.
In reality, urbanization bias is a gradual process.
Picking a single rural to urban threshold variable is too subjective, and arbitrary.
Urbanization bias is a continual process that gradually
becomes greater as a rural village with a weather station becomes a small town, then a large town, then a small city,
and then a thriving metropolis.
By taking a very simplistic approach, most of the studies
failed to properly distinguish between the true climate trends, and urbanization bias.
Most studies seem to have assumed if you could divide stations into two subsets – rural and urban — using a single variable,that was good enough to estimate urbanization bias.
I disagree.
Th information below is from somewhere on this website, in 2010:
The “urban heat island “effect is greater for a rural station
becoming slightly urbanized, than for an urban station
becoming slightly more urbanized R. Spencer
“The global average urban heat island effect in 2000 estimated from station temperatures and population density data.”
“Peterson, 2003 assumed that a station was urban once the nightlight brightness in the area, measured by satellite,
reached a certain value.
In reality, urbanization bias is a gradual process.
Picking a single rural to urban threshold variable is too subjective, and arbitrary.”
Richard, once again you prove what a joke Climate Science is. What kind of “science” doesn’t standardize their measuring specifications? They just take all stations, garbage, corrupted, moved, Urban, Rural etc etc etc and then throw them all together and claim that they can somehow produce a valid temperature chart. I’ve said countless times and used Desert Locations to prove it, that the increase in temperature recorded in the NASA GISS Global Temperature Graph is nothing more than a measure of the UHI and Water Vapor Effect.
Any real science would have specifications for stations that meet the requirements of no UHI or Water Vapor to be included in the Composite. I created a list of 265 Stations that show no warming.

Simply identify desert locations, dry and cold, and you will see there is no warming, even when CO2 increases from 300 to 415 ppm.

On a global average basis it looks like this: https://watervaporandwarming.blogspot.com https://drive.google.com/file/d/1_2m02r30FmvtgSnOEZunFRpUJwTUFU_V/view?usp=sharing
That link shows that measured WV is increasing faster than possible from global average surface temperature increase which demonstrates that CO2 has no significant net effect on climate. This agrees with CO2islife finding.
The graph at https://drive.google.com/file/d/14PxMjIbvcLoe-iY9lVefM-CVTsj6_quZ/view?usp=sharing shows a comparison of measured temperatures with calculated temperatures assuming no contribution from CO2.

Done. The link looks the same but now you can see the graph.
Thanks for the note
CO2…”Richard, once again you prove what a joke Climate Science is”.
If you go back to the roots of the IPCC you can see why. It is based on the thoughts of Margaret Thatcher which were based on a fight she was having with UK coal miners. She was exasperated with her inability to control them.
She had a degree in chemistry and an advisor urged her to take it to the UN, to scare them onside by the fear that emissions from coal could cause global warming, hence the need to shut down coal mines. She did, and the UN bought it.
Of course they bought it. Since the 1960s, the IPCC has been looking for a way to form world government in order to impose taxes on wealthy nations to support less fortunate countries. The IPCC has no interest in science, they are a child of the UN and the real motive is world government.
The first co-chair of the IPCC was John Houghton, a protege of Thatcher. He was also a climate modeler and he imposed model theory as a basis of IPCC thought processes. Houghton once declared that it was necessary to scare the public onside, otherwise no one would listen.
Since then, all forms of pseudo-science have been employed to support the AGW theory. It is disgraceful to me that organizations such as NOAA, GISS, and Had-crut should buy into deceit in order to enable such pseudo-science.

My comment:
Did you mean the Catastrophic CAGW theory?
The AGW theory (man made global warming) is not deceit.
It’s based on real science in a laboratory, proving CO2 is a greenhouse gas.
The effect of added CO2 in the atmosphere is not known, and not knowable.
To claim it is “significant” is speculation.
I accept the infrared gas lab spectroscopy experiments as real science, and have no problem assuming CO2 has some warming effect (by interfering with our planet’s ability to cool itself).
On the other hand, I favor a lot more CO2 in the atmosphere to accelerate plant growth, increase crop yields, and green our planet, based on thousands of real science experiments, and the experiences of greenhouse owners.
If that extra CO2 causes any warming, the warming should be mild, and harmless.
That’s what the lab experiments suggest, and that’s what has happened in the past 45 years.
There is no evidence of a water vapor positive feedback that would triple the warming suggested by the lab experiments caused by CO2 alone — changing harmless warming, to potentially harmful global warming.
I reject the always wrong, wild guess predictions of a coming climate crisis.
They started in the 1960s, and I’m tired of hearing them.
Unlike the climate alarmists, I have noticed that the locations and timing with the most warming since the 1970s were colder areas, mainly during colder times of the year, and mainly at night.
Which makes the mild warming pleasant — and pleasant is better than harmless.
Meanwhile, It’s really cold where I live in southeastern Michigan, and has been for a week.
That is a global warming “emergency”?
It has been so cold in Texas recently that wholesale electricity prices have gone through the roof.

I was referring to the way shysters like NOAA, GISS, and Had-crut have taken the good lab work of Tyndall, circa 1850, and built it into pseudo-science. As you say, there is no way of knowing the effect of CO2 with regard to warming.
We can use our own speculation based on real science. For one, CO2 makes up only 0.04% of the atmosphere. I have heard all forms of rebuttals on that, from the effect of a drop of ink in a glass of water, but not one addresses CO2 as a mix in a gas. So I gave my own view on that.
I realize the atmosphere is a turbulent mixture of gases that creates an impossible situation for analysis. All the same, if you could reduce the atmosphere to a static mixture of gases, where the Ideal Gas Law applies, we can see the effect of 0.04% CO2 in that mix.
First, we must presume a relatively constant volume, or break the atmosphere into layers small enough where the IGL might apply. Given constant V, we have PV = nRT. With a constant v we can write:
P = (nR/V)T
That tells us that with a constant volume and number of molecules (n) that P is directly proportional to T.
Next we apply Dalton’s law of partial pressures. It tells us that the total pressure of a gas equals the sum of the partial pressures of each gas. Since partial pressures are almost directly proportional to the mass percent of each gas in the mix, and since those partial pressures must also generate temperatures in proportion to the overall temperature, the 0.04% of CO2 can never exceed a contribution of 0.04C per degree C warming.
In the AGW theory as applied in models, that 0.04% is given a warming factor of 9% to 25%, depending on the amount of water vapour. The Ideal Gas Law tells us you cannot simply assign an arbitrary number to the warming effect of CO2.
When I use the term AWG, I am referring to the corrupted version, not the inferences of Tyndall and Arrhenius. I fully accept that gases like CO2 and WV can absorb electromagnetic energy and warm. As you know, the atmosphere is not a lab where a gas can be constrained to a long tube in which it is exposed to infrared energy from a burning flame.
Gordon Says: If you go back to the roots of the IPCC you can see why. It is based on the thoughts of Margaret Thatcher which were based on a fight she was having with UK coal miners. She was exasperated with her inability to control them.
Yes, thanks Gordon. There is a Documentary “The Great Global Warming Swindle” that details that.
I once saw a documentary detailing how aliens came to our planet and Egyptians worshipped them.
I hope those aliens come back to disprove AGW.
Australia has a climate temperature record going back to the 1860s. Since about 1900, there have been hundreds of digitised station records to choose for research on matters like UHI. Australia also has a great deal more open space than many countries, so it lends itself to examination of the “urban minus rural T” approach to see what UHI there was.
In 2011 I separated out some 44 stations that any reasonable observer would label “rural”. I have been to many of them. At the time, I even called them “pristine”. These were to form a basis of rural stations to compare with another selected set of “urban”. It never got that far. There was too much noise in the data. Too many missing values. Too much repeat data where a month of temperatures were copied to fill in another month of missing obs. That sort of thing. I chose 1972 as a start year because conversion of deg F to deg C happened that year; and 2006 as the end year because my digital data source ended in March 2007. Both Tmax and Tmin were analysed. I started with daily data, infilled, then averaged it to annual.
Here are the numbers, in easy Excel form, for any readers here to crunch. It is easy to do.
http://www.geoffstuff.com/pristine_44_2018.xls
The more isolated the station, the poorer the quality, it seemed.
There was so much missing data that infilling gave different final results depending on who did the infilling, or whether the missing data were just ignored instead of invented. These numbers here are invented by inserting a rough mean of the data just before and after the missing data on a daily basis.
If you extend the time scale from 1972-2006 to 1972-2020, the trends alter substantially, some from negative trends to positive, some the opposite, for the small number of updates that I did recently.
The data are not stable enough to derive much of interest. As the spreadsheet analysis shows, you can get the temperature trends to correlate with all sorts of extraneous variables. The trends even have a pattern when plotted against the stations numbers from the World Meteorological Organization, when they should not.
If anyone, including Dr Spencer, think that you can extract useful UHI relations from these numbers, go ahead. I dare to say that you cannot. I cannot comment on the method of relating UHI to population, because just about all of these stations have essentially zero population within reach. However, from years of other UHI work, I cannot support the use of populations of people, of night lights or anything else. There is simply not enough recorded aboservation about enough sites with adequate quality to start to generalise and draw inferences. And, at least in Australia, there is not enough quality in the rural temperature data. It was never designed for this type of use and it is simply unfit for purpose. Geoff S
Geoff.
Are you saying that the data we are basing major decisions on has been fabricated?
If its not reliable enough to use to determine UHI effect surely it is not reliable enough to show a warming effect in general.
MW,
“Fabricated” is too strong a word. As part of a team we have just started making a renewed effort with better software and are finding more and more examples of shoddy raw data in the official Australian temperature numbers. We tend to put these down to lazy or naive sorts of efforts by people transcribing from handwritten original observation sheets to digital forms. Fabricated implies an evil intent to do something wrong and I am showing no evidence for that yet with Raw data. We are not talking adjusted data here.
My main point is that there is too much noise of various types to perform other than very rudimentary analysis. If people calculated proper, official estimates of uncertainty they would soon find that many attractive ways to use the numbers are defeated by noise before they even start to get anywhere.
bdgwx says: February 13, 2021 at 10:06 AM “The uncertainty is actually less than 0.1C and has been since at least 1960.” This is no more than a public statement of scientific ignorance, made worse from the safety of nobody being able to go back in time with a thermometer and on the same day, to replicate. Easier to fib when you can’t be caught.
I have tried to get an uncertainty extimate from the BOM for several years now, but they have declined several times to give one. Their responses have been “obfuscation”, “work in progress”, “hope to publish a paper soon”, “have a read of what was said at this conference last year”, that type of deflection.
I used to own a lab where our future income depended on giving estimates of uncertainty for our measurements that clients could test openly or secretly by easy methods. If we failed, the enterprise failed. It would be interesting to read of overall uncertainties claimed by NOAA and GISS and Berkely and UAH, so that there was some material to work on as to how good those estimates are.
If the uncertainty is less than 0.1C as bdgwz claims, then ten people with a thermometer each would be able to go to a time and place, measure temperature, then compare results. Chance that 66% would fall within +/- 0.1C is remote. Then, start accounting for other known factors that can affect temperatures and you are more likely to go beyond +/- 1C. With that noise, it is not quite proper to try to derive trends of less than that per time, as a rough rule of thumb.
Many publications in other areas of science exist for the proper calculation of errors and uncertainties. One of the hallmarks of climate research is the rarity with which proper, recommended, explained, sometimes even officially mandated methods are even mentioned, let alone performed properly. Geoff S
Geoff said: If the uncertainty is less than 0.1C as bdgwz claims
It’s not my claim. It is the result of peer reviewed analysis.

Geoff said: then ten people with a thermometer each would be able to go to a time and place, measure temperature, then compare results.
What? That doesn’t even make any sense. How can ten people take a single reading a specific time and place and report a global mean surface temperature value?
Geoff said: Chance that 66% would fall within +/- 0.1C is remote.
Actually that is 2 sigma so it is a 95% confidence interval.
Geoff said: Many publications in other areas of science exist for the proper calculation of errors and uncertainties.
Agreed. That’s why none of this is a mystery.
Geoff said: If the uncertainty is less than 0.1C as bdgwz claims
Badwax replied:
“Its not my claim. It is the result of peer reviewed analysis.”
My comment:
That is pal reviewed baloney.
There is no way to calculate a margin of error when there is so much guessing (infilling) that can never be verified.
In addition, the measurement instruments are not likely to have +/- 0.1 degree C. accuracy, and checked regularly for accuracy, especially before World War II, so the claim of +/- 0.1 degree C. for the global average temperature is science fraud.
No bogus “study” will overrule common sense … except for you badwax — a victim of the appeal to authority logical fallacy (if government paid/granted bureaucrats say so, then it must be true).

You spend your free time here to produce discrediting and denigrating remarks about lots of things you yourself would never be able to do.
That is what I call bare pseudoskepticism.
Thanks for that!

RG said: There is no way to calculate a margin of error when there is so much guessing (infilling).
And yet the authors listed on the publication figured out how to do it. And it’s not just them. Other institutions who publish global mean surface temperature datasets have quantified their uncertainty as well. Here is BEST publication.
https://static.berkeleyearth.org/papers/Methods-GIGS-1-103.pdf
RG said: that can never be verified.
Sure it can. I promise you that you’ll be able to figure out how to verify GISTEMP’s method (and others) of interpolation in a matter of minutes. It is mind numbingly obviously how to do it. Take a stab at and post back.
RG said: In addition, the measurement instruments are not likely to have +/- 0.1 degree C. accuracy, and checked regularly for accuracy, especially before World War II, so the claim of +/- 0.1 degree C. for the global average temperature is science fraud.
It’s a good thing 0.1C accuracy is not required on individual instruments then. In fact, as a first approximation and with 8000 subboxes GISTEMP only requires about 4C of accuracy on each subbox to yield a 0.05C standard error of the mean. E = S/sqrt(N) = 4/sqrt(8000) = 0.045. Note that in reality the uncertainty quantification is vastly more complicated. Read the paper.
RG said: except for you badwax
Seriously?
You can’t guess temperatures for many grids, and then claim you know the margin of error for a global average, and it is tiny, especially in the Southern Hemisphere before 1900, with far too few measurements.
No amount of high level math, Ph.D. degrees and mathematical mass-turbation will chage that fact that the accuracy of unverified guessed/infilled temperature numbers, plus measurements using buckets and thermometers, mainly in shipping lanes in the Northern Hemisphere, with a margin or error likely to be +/- 0.5 degrees for untrained sailors … somehow ends up as a +/- 0.1 degree C. margin of error for the global average.
That +/- 0.1 degrees C. claim is science fraud.
RG,
If the margin of error on each subbox is 0.5C then the standard error of the mean is E = 0.5/sqrt(8000) = 0.002C.
bdg…”Its not my claim. It is the result of peer reviewed analysis”.

Hilarious…a paper co-authored by Gavin Schmidt and James Hansen, two of the biggest alarmists who ever walked the planet.
Your naivete knows no bounds and your appeal to authority the same.
Are you aware that Schmidt sat on a review board as an editor at the Journal of Climate? The paper was likely reviewed by him and or his buddy, Michael Mann, who was an editor on the same journal.
Peer review no longer means a darned thing. It has been hijacked by idiots. When Australian researcher, Barry Marshall, submitted a paper claiming to have found a bacteria, h. Pylori, that could survive in stomach acid and create ulcers, his paper was rejected BEFORE it got to peer review.
The journal editor listed Marshall’s paper as one of the ten worst ever submitted. Can you imagine what kind of idiot that idiot would have appointed as a reviewer? Marshall had to drink a concoction with H. pylori in it, making himself very ill, then healing it using antibiotics before anyone would listen.
If the idiots in the peer review journal had gotten their way, and Marshall did not have the guts to proceed with his proof, we’d still be treating stomach ulcers with antacids and getting nowhere.
I’m sorry, modern peer review is often utter garbage and that’s pertinent to the climate sciences where peer review has been hijacked by the likes of Schmidt and Mann.
Ask Roy or John of UAH about peer review. They struggle to get their papers published. And when they have succeeded, people like Kevin Trenberth have hounded journal editors to get their papers withdrawn.
Climate science peer review is rigged.
The entire world has had 33 years to review the GISS method and 18 months to review their more rigorous uncertainty analysis. They’ve had 7 years to review the BEST method and uncertainty analysis. Can you post a link to a peer reviewed publication presenting an alternate analysis that comes to a significantly different conclusion?
sorry bdgwx but you are expressing an argument from ignorance. The surface doesn’t warm from something simply because we are ignorant about how multiple layers of greenhouse gases get heat back to the surface.
I am convinced that greenhouse gases are absolutely necessary for warming the actual radiating surface of the ground and sea but that is only line of sight and doesn’t explain the greenhouse effect as expressed by our climate temperatures. There is difference between surface radiating power and climate and radiation does not explain it all. Radiation only explains a lot at some virtual surface high in the sky. . . .and even there one cannot go so far as define an equilibrium as defined by Stefan and Boltzmann. The frustration and complications of doing that has actually created the necessity of an abandonment of science in order to express a particular theory.
It is an easy and common abandonment that auditors frequently note where form dominates over substance. It is a most common issue found in the most regimented of governments and large institutions where substance becomes defined by ‘accepted’ symbolic forms.
bill,
I fail to see the connection between your post above and the quantification of the uncertainty in GISS’ land-ocean temperature index. That is what is being discussed in this thread.
with all due respect bgdwx, your statement was the world had 33 years to review the GISS method.
The assumption you express is that there is a reliable means of reviewing it.
Scientific peer review doesn’t ensure the methods are adequate and reliable. All scientific peer review does (when not engaged in political obstruction) is ensure there is not any conflict with better understood science within the narrow window of the peer reviewer’s expertise and beliefs.
Scientific peer review is not a professionally designed independent full spectrum look at a science paper.
Much of the talk recently on ”red team” peer review has been designed at broadening the examination. There have also been professional team recommendations of that sort given to the IPCC which have only partly been implemented.
Process is everything. Literally tens of thousands of science papers or more would not stand up to full examination to at all any degree that say corporate financial statements must withstand or sat FDA drug approval moving into the science realm.
It seems clear to me with all the claims of harm to health and finances AGW science should be so examined. . . .and actually to some extent it has been as the government hasn’t completely caved in to all this. . . .some harmful stuff but mostly aimed at politically already sensitive topics like the keystone pipeline, coal mines and few other things.
bill said: The assumption you express is that there is a reliable means of reviewing it.
If the collective intelligence of 7 billion people is insufficient to reliably review GISS’ method and uncertainty quantification then what more are you looking for?
Peer review at the journal level is only meant to keep publications with egregious mistakes from spamming the system. The “real” review occurs when that publication is presented to the entire world. The Hansen 1987 methods publication has been available to the entire world for 33 years. And although there are several legitimate critiques of it no one has expressed any serious objections at a fundamental level regarding their method and quantification of uncertainty.
I have to be honest…I think the GISS method elementary. I’m critical of it because it is so simple. More dynamic methods like kriging, local regression, etc. would be more appropriate IMHO. But I do have to concede that something can be said for simplicity and the fact their results match others is quite compelling.
bdgwx my response is in part here: http://www.drroyspencer.com/2021/02/urban-heat-island-effects-on-u-s-temperature-trends-1973-2020-ushcn-vs-hourly-weather-stations/#comment-618262
and is in part because GISS doesn’t come up with the same result as others.
bill said: and is in part because GISS doesnt come up with the same result as others.
Yes they do. And it is remarkable because the between NASA, NOAA, Hadley, Berkeley Earth, Cowtan & Way, and Copernicus we have techniques ranging from NASA’s subbox method to C&W’s kriging method to Copernicus’ 4D-VAR method with each using a different subset of available data. BTW…make sure you check out how well CMIP5 model predictions match observations while you’re on the page. Oh…and notice that like any true scientist Dr. Hausfather cites his evidence for everyone to review.
https://tinyurl.com/7cglt5l9
bdgwx the graph you present shows a difference of .15 between the surface records. That provides additional evidence that the GISS claim of .1 accuracy is bogus.
And of course all that exists on that graph are surface records subject to UHI influences. UAH is another ~.13 additionally less (roughly estimated) from the coolest of the surface records. But UAH is largely immune to UHI.
So rather than arbitrarily attacking one or two of the records, the difference could largely be UHI and variations on how that UHI is gathered and treated providing a similar margin of difference between the surface records themselves.
Roy in this post has developed a means of somewhat ground truthing that argument. I wish him the best of luck in continuing his research and gaining additional budgets to expand it.
Remember these are 2-sigma uncertainty values for a single value. That means there is a 5% chance the error is more. When comparing the two or more values you have to use summation in quadrature. So using 0.1C as the basis for both values we expect disagreement at 95% confidence of S = sqrt(0.1^2 + 0.1^2) = 0.14C. That means on average we expect a disagreement of >= 0.14C every 20 years between 2 preselected series. The probability of a disagreement of >= 0.14C between any 2 of the 6 series in any given year is thus 1-(1-0.05)^15 = 0.54 or 54%. In other words, we expect a disagreement >= 0.14C between 2 of the 6 series about once every 2 years. Obviously in reality it does not occur that often. That is because the 95% CI is actually closer to 0.05C after 1970.
BTW…this does not factor in systematic biases like is the case with the NOAA and Hadley temperature series. Those are only partial sphere measurements and do not adequately cover the Arctic region. This lowers their warming trends since they exclude the fastest warming region from their global mean temperature calculation. As a result they will deviate more and more from the others as time goes on. That is why NOAA and Hadley will be more likely to break above the 0.14C error margin and the probability of such an occurrence increases with time.
I will say that Had.C.R.U.T version 5 has just recently been published. v5 moves from 80% coverage to near 100% coverage like what NASA and BEST achieve. Note that Copernicus uses the very different and vastly more complex 4D-VAR method. That is a subject for a different discussion though.
I read the paper referenced in your comment and it is a pile of steaming farm animal waste products: The goal was obviously to use mathematical mass-turbation to justify bogus claims of tiny global average temperature statistics margins of errors, using mathematical guesswork (extrapolation of missing data) called kriging.
There is far too much missing temperature data before 1900 for the claim of a +/- 0.1 degree C. margin of error in the stated global warming since 1880.
Most of the planet had no weather station coverage before 1900.
For sea temperature “measurements”, areas outside normal shipping lanes were generally ignored, with few measurements in the Southern Hemisphere.
Using buckets and thermometers. Ha ha
You can’t extrapolate accuracy, to the nearest 0.1 degree C., starting with no data for most surface grids on the planet.
The coming climate crisis alarmists promote many misleading claims:
Claimed global average temperature margin of error of +/- 0.1 degree C. since 1880
Claiming to actually know the global average temperature in the 1800s.
Claiming a theoretical water vapor positive feedback effect, tripling the alleged warming effect of CO2 alone, that has never been seen in actual temperature measurements in the past 50 years.
Using climate computer games that predict more than double the actual warming since 1979.
Over 50 years of predicting a climate crisis as the actual climate gets more moderate, and more comfortable.
Promoting a single global average temperature that no one lives in, while ignoring the locations and timing of the most warming since the 1970s, such as warmer winter nights in Siberia.
Claiming future global warming will be a “climate emergency”, completely unlike the mild, pleasant global warming since the 1970s, that most people have enjoyed.
Demanding the replacement of reliable sources of electric power, at great expense, with unreliable wind and solar power.
Refusing to debate climate science, rudely attacking skeptics as “science deniers”, falsely claiming climate science is settled.
This all adds up to junk science used for climate change scaremongering.
How about real air pollution over many Asian cities from burning fossil fuels without modern pollution controls.
Who cares about that pollution?
Not the climate alarmists.
How about one billion people in the world with no electricity.
Who cares about them?
Not the climate alarmists.
RG said: I read the paper referenced in your comment and it is a pile of steaming farm animal waste products:
Fine. Now here is where you need to present evidence backing up your position. The most convincing evidence you can present is a dataset that publishes a global mean surface temperature accompanied with an uncertainty analysis that comes to a significantly different conclusion.
RG said: There is far too much missing temperature data before 1900 for the claim of a +/- 0.1 degree C. margin of error in the stated global warming since 1880.
That paper does NOT claim +/- 0.1C of error since 1880.
RG said: You cant extrapolate accuracy, to the nearest 0.1 degree C., starting with no data for most surface grids on the planet.
GISS, BEST, NOAA, JMA, Cowtan&Way, Had.C.R.U.T, UAH, RSS, the half dozen so reanalysis in datasets in widespread, etc. have no problem doing it.
Just because you don’t know how to do it doesn’t mean everyone else is as equally perplexed.
RG said: Using climate computer games that predict more than double the actual warming since 1979.
No. I’m sorry that statement is not right. See Hausfather 2019.

“There is far too much missing temperature data before 1900 for the claim of a +/- 0.1 degree C. margin of error in the stated global warming since 1880.”
It is truly amazing how RG makes generalized hand-waving claims, with no calculations offered whatsoever, and in the end somehow comes to a quantitative conclusion!
Badwax
Perhaps someday in your life your wisdom will increase to the point where you realize the answer to many questions is
“we don’t know”.
Right now you are at a lesser level of wisdom — you love the appeal to authority logical fallacy ( they just HAVE to be right — they are EXPERTS — experts ALWAYS have answers — they NEVER say “we don’t know”, even when they don’t know ).
The comparison of computer games I previously mentioned was for UAH satellite “temperature” data and CMIP5 models, from 1979 to 2019. The models predicted more than double the actual warming in the UAH statistic.
The numbers would be different using surface statistics and different start and end years, but in general, the average model has ALWAYS over-predicted warming, and have not been getting more accurate over time.
Your sentence:
“Just because you dont know how to do it doesnt mean everyone else is as equally perplexed.”
… was a sophisticated character attack (did you hire a ghostwriter?), but it was still a character attack. Character attacks don’t refute anything, except the character of the person typing them. I would never do that. ha ha
… To Nasty Nate, who blabbered:
“It is truly amazing how RG makes generalized hand-waving claims, with no calculations offered whatsoever, and in the end somehow comes to a quantitative conclusion!”
My response:
I was NOT waving my hands — that’s how I type.
BS detection does not require alternative calculations. BS detection requires repeatedly asking the question “How do they know that?”
That’s an important question.
Because people often claim to have knowledge they do not have. They state answers to questions, when they do not know the answers. They claim their data are very accurate, when they are not. They resist saying “I don’t know”. They assume their credentials/college degrees/government position will keep people from asking the obvious question: How do you know that? And never accepting a simple answer, such as: ‘A peer reviewed study by Professor Joe Schmo” (the good old appeal to authority).
The global average temperature in the 1800s is a rough guess, no matter what any scientists claim, because of such poor global coverage, not to mention the not very precise bucket and thermometer methodology for 71% of the planet.
The future climate is unknown, and for over three decades, climate computer game predictions have been worse than a “more of the same” prediction, which seems to be what the Russian INM climate model predicts, with great success.
The claim of a water vapor positive feedback has no proof from climate history, and doesn’t even make sense — a positive feedback “runaway warming” would have destroyed the planet long ago.
The claim that we are in a “climate emergency” is wild speculation, that completely ignores actual experience with global warming in the past 45 years, which was pleasant for most people, and beneficial for plant growth.
RG,
You are absolutely right. My level of wisdom on climate science topics or any topic really is vastly inferior as compared to others. One thing I’ve learned over the years is that the more I learn the more I realize how little I actually know. So you definitely got that part right.
I do not appeal to authority. I appeal to evidence. You will often see me appealing to evidence either directly or indirectly by proxy by deferring to an authority who herself appeals to evidence. Note that I will never assume as fact something just because of who presented the evidence. It is all about the evidence itself. Don’t mistake my name dropping as appealing to authority. There is a difference between appealing to authority and deferring to authority. I defer to authority because 1) I recognize my own incompetency 2) that is the way you look up peer reviewed publications and 3) because it is considered plagiarism to present the work of others without proper citation.
And none of this has anything to do with your character. As I’ve said before I’m sure you are a great person with a fine character. But even great people with infallible characters encounter problems they can’t solve. Just because they were perplexed by the problem doesn’t mean that everyone was as equally stymied by it. That is my point. And I will be the first to admit that there is a whole array of problems that I can’t even begin to understand how to solve. I wish I had a better understanding of the climate than currently do.
Going forward just understand that pesky skeptics like me are convinced not by “nuh-uh” arguments but by “here’s how to do it better” arguments that are backed by vetted evidence. If you think +/- 0.1C is unreasonable then clearly and concisely describe how that publication got it wrong and how they should fix the problem. Get it peer reviewed. Then provide a reference to a dataset that also computes the global mean surface temperature accompanied by a rigorous uncertainty analysis that comes to a substantially different conclusion. I will then weigh that equally against all of the other pieces that compromise the body evidence. It is fair and it is reasonable.
“There is far too much missing temperature data before 1900 for the claim of a +/- 0.1 degree C. margin of error in the stated global warming since 1880.”
“BS detection does not require alternative calculations.”
Yes, yes it does.
Again Richard, you make a quantitative statement above. And you still havent added any quantitative backing for that.
“BS detection requires repeatedly asking the question ‘How do they know that?’
That would be a fine question.
But you not knowing how they do that, is not equivalent to ‘theyre doing it wrong’ or ‘its a steaming pile of whatever’, is it?
bdwdx sez:

My comment:
You have described your own appeal to authority logical fallacy BETTER THAN I COULD. Thank You. For you to believe something, it was written by someone with a science degree and peer reviewed. That provides the authority you require.
What you don’t realize is that advanced degrees ans peer review do not create truth. In fact, peer reviews tend to create conformity (needed to get published).
Many peer reviewed studies make predictions of the future climate, which are speculations, not science at all.
Especially after so many decades of inaccurate predictions by climate models. No amount of peer reviews makes climate predictions accurate.
Yet the ‘coming climate crisis’ is based entirely on predictions of doom. No attention paid to the people on our planet who have lived with pleasant global warming for the past 45 years — the predictions are ALWAYS for bad news. The future climate can never get better? The future must be bad? That’s not science, it’s more like a religious belief.
The sparse global coverage before 1920, and especially before 1900, requires a lot of guessing to infill data free surface grids.
There is no honest way to guess so many numbers and then claim you even KNOW the margin of error.
It is especially wrong to claim a +/- 0.1 degree C, margin of error for pre-World War Ii temperatures, when that precision may not even be possible today.
Worse than claiming great accuracy of the past climate data, which at least is supported by some measurements, is grossly over confident predictions of the future climate, using a TCR from the 1970’s, that apparently never changes, even though it overstates actual measured warming.
AGW is real, and harmless.
CO2 is likely to cause some warming — amount unknown.
Older temperature measurements are approximate, and their accuracy is unknown, not +/- 0.1 degree C.
100 year climate predictions are climate astrology.
CAGW is scientific speculation, at best, and left wing propaganda, at worst.

First off peer review serves a very narrow purpose in science. It does not come close to providing a means of validation. Validation in science comes from experiment and observation, not peer review.
Second, you say you will weigh the evidence after peer review. Yet you say its way beyond your understanding.
Third, I don’t see anything wrong with Richard’s post. He is expressing skepticism where skepticism is due. Its clear the situation is worse than looking for a needle in a haystack. Warming has been gentle and its been good for mankind. Technological advance comes from having the time and wherewithall to devote to exploration.
Fact is all of us have a lot more than we need. thats why we devote time to this forum. But skepticism is really writing it all off like Richard is doing until it actually proves to be something positive. Unfortunately its evolved beyond exploration which of course is a huge potential waste of resources. there is almost certainly more important fish to fry.
RG,
There is still a disconnect here. You keep saying that +/- 0.1C isn’t possible, yet all of the available evidence suggests that it is. You provide no alternative quantification of the global mean surface temperature and associated uncertainty. You don’t even provide commentary as to how you think NASA, NOAA, BEST, Had.C.R.U.T, etc. got it wrong. That is what I’m challenging you to do. If you won’t or can’t provide this kind of analysis then I have to choice but to fall back on the abundance evidence that is already available.
bill,
I think you may be misunderstanding what appeal to authority means. Appealing to authority means you accept a claim because of who made the claim. For example, accepting that the GMST has an error < 0.1C after 1950 only because Gavin Schmidt said so and for no other reason is appealing to authority.
Appealing to evidence means you accept a claim because of the evidence that was provided. It doesn't matter who's names are on a publications. The publication and all content within are the evidence. And when that evidence has survived whatever critiques have been leveled against we have confidence that it represents reality. For example, accepting that the GMST has an error < 0.1C after 1950 because there exists a publication detailing the methods and calculations used showing as much and having that content reviewed by experts in the field and the entire world without any significant criticisms leveled against is appealing to evidence. It doesn't matter if Gavin Schmidt's name is on the paper or not. The paper could have any been submitted anonymously and it still counts as evidence. It is the content itself and not not who published it that matters.
Deferring to authority is accepting a claim not because of who said it, but because that person demonstrated that their claim is supported by evidence. For example, I am completely incompetent in the field of neuroscience. But I will defer to an authority on any neurological ailments I might have as long as that authority has demonstrated that their diagnosis and treatment plan is supported by evidence. Deferring to authority is NOT the same thing as appealing to authority. It all has to do with whether evidence plays a central role or not.
I'm going to give you the same challenge I gave RG. If you want to convince me that the GMST has an error larger than 0.1C after 1950 then you need to present evidence to back up that claim. Evidence includes a publication that computes the GMST and provides a rigorous quantification of the error. Enough details need to be provide so that the results can be duplicated.

Sorry for the double post but missed erasing a lot of my quote.
bill,
The claim (backed by evidence) is that global mean surface temperature anomalies have less than 0.1C uncertainty for years after WWII.
There is a difference between the uncertainty on individual monthly values and the uncertainty on the linear regression trend.
The GISS 2-sigma uncertainty on the +0.192C/decade trend from 1979-2020 is +/- 0.011.
The GISS 2-sigma uncertainty on the +0.075C/decade trend from 188-2020 is +/- 0.002.
Not only am I going to argue that the science is adequate enough to know the monthly global mean surface temperature anomalies to within 0.1C after 1960, but I am also going to argue that the linear regression trend of those anomalies is known to within 0.002C.
My evidence is the various datasets that publish a GMST and accompanied uncertainty analysis the raw output from Excel’s LINEST function.
bdgwx, your response is just a bunch of mumbo jumbo. Differences between different temperature records vary over .1degC at all levels, monthly, annually, decadal. And all the records combined aren’t going to provide the boundaries of potential error.
bill,
Don’t move the goal post. We are NOT discussing the variance in the individual temperature readings. We are discussing the standard error of the monthly and annual means. That is a completely different topic.
bdgwx you are the one moving the goal posts. I responded to your comment about ”accuracy”, not standard error.
Standard error is a poor indicator because it assumes error is random. This entire thread is not about ”random” error.
bill,
Accuracy is a non-factor here because we’re using anomalies. If there was an accuracy bias on the measurements then it cancels out via the use of anomalies.
For example, let Mb be the basis and Mm be the monthly mean, and B be the measurement bias. The anomaly A is…
A = (Mm+B) – (Mb+B)
A = (Mm-Mb) – B + B
A = Mm-Mb
Notice how the accuracy bias B cancels out. This is actually one reason why most people use anomaly analysis in the computation of the global mean temperature.
This is why when I see the word “accuracy” I implicitly understood it to mean “precision”.
I just looked…shame on me for using the word “accuracy” in one of my posts above when I should have used “precision” or “uncertainty”. That is on me. I’m usually careful about things like that. I guess I just overlooked it this time.
I will say that accuracy does come into play when you want to compare one time series to another. But that is a different topic.
But regardless this is all mostly moot because variance is still a different concept from either accuracy or precision. You’re still moving the goal post here.
bill,
I will say that the bias B in Mb+B and Mm+B above assumes that there is no time dependence. In other words, I probably should have labeled things as Mb+Bb and Mm+Bm and then said I’m assuming Bb = Bm. And for the most part that is a safe assumption. The issue that arises here is that Bb and Bm could deviate with time introducing a bias independent of the statistical uncertainty of the measurement. This is the case for UHI, TOB, instrumentation, etc. issues. But, and this in important, the bias is estimated at 0.01C. It is a value that is nearly one order of magnitude less than the statistical uncertainty. See section 4.2 on Bias Uncertainty.
What you need to do bdgwx is realize that standard error is only a relevant concept to random sampling. Right out the box even GISS wouldn’t argue that their sampling program is random.
In my view folks like Gavin Schmidt only throws those kinds of numbers around to con people into thinking it means something. Mathematicians sometimes need to come out of their shell and smell the coffee.
Snowstorm in Texas and Louisiana with very cold temperatures. This is the result of an unusually strong stratospheric attack in the US.

The stratospheric forecast for five days does not predict major changes in the weather. Still heavy frost in the same areas of the US with a small shift eastward.

Very dangerous freezing rain in Louisiana and Mississippi.
Thanks Geoff.
I wasn’t suggesting the numbers were fabricated,
I just wanted to query how data which relates to one study could not be used in another study.
I find the whole aspect of data measurement and the use of that in climate change confusing.
It seems to me as a non climate scientist that if a measurement doesn’t fit the model the data is deemed wrong rather than the model and the assumptions that the model is based on.
Maybe CONUS will have to suffer a while longer, but it seems that in Northern Germany, we slowly come out of this cold weather phase:

Yahoooo! Even if it will take a while for this bloody snow to disappear, I’m happy, because… I don’t like it cold.
And… it was really funny to see at WUWT all the Coolistas claiming as usual the Grand Cold soon coming back, just because the Thames got frozen here and there.
So what! Weather is weather, and climate is climate.
J.-P. D.
I dare say if CO2
I was going to say if CO2 levels were back to levels a 100 years ago I bet the temperature trend would have been about the same.
Then bindidon,
Do you think the property called “closure” on which the climate study is based,
Regardless of the chaotic behavior of the short-term meteorological weather study (10-14 days), it is sufficiently proven or experimentally contrasted. How to believe in the prediction capacity of the IPCC models?
Note:
(Beyond the discussion about the noise that may be in the shot
or transcription of some data or data series … or the possible bias in the temperature homogenization criteria ,,,)
Adelaida
I apologize, but… I really don’t know what you are here referring to.
Please add some explanation helping me in identifying what you mean.
J.-P. D.
It looks like real scientists are finally taking a look at the data:
New Study Finds 25-45% Of The Instrumental Warming Since The 1950s Is Due To Urbanization, Not CO2
https://notrickszone.com/2021/02/15/new-study-finds-25-45-of-the-instrumental-warming-since-the-1950s-is-due-to-urbanization-not-co2/
Funny how an amateur Climate Data Scientist like me could have reached that conclusion blindfolded.
Urbanization = man made
They got the “man made” claim right = half credit?
CO2…”Funny how an amateur Climate Data Scientist like me could have reached that conclusion blindfolded”.
I am sure quote a few have reached this conclusion but getting the message out there is the problem. If you go the scientific route you have to get the paper through biased peer review. If you go the media route, you will likely never get covered by a major media outlet, who are seriously biased toward CAGW.
I am sure there’s a way, if enough people put their heads together.
“It looks like real scientists are finally taking a look at the data”
UHI has been assessed using observational data for decades.
What you mean is, “This researcher agrees with nme, so that makes them a real scientist.”
Geoff Sherrington
Thank you for the valuable comments concerning your BoM data analysis.
I downloaded your pristine_44 Excel file, had a quick look at it, but there is a lot on the FIFO stack to be done before.
While you prefer to zoom into single stations, I prefer to stay on their average level.
Here is a comparison of the Australian GHCN daily data set with UAH6.0 LT AUS, made a while ago till Dec 2019:
https://drive.google.com/file/d/11G0ce_SU-4Sd8vDrk58FhkCe8YQztu98/view
I like such comparisons of temperature measurements differing by about 24 C.
J.-P. D.
Sorry Bindidon and Thanks for responding !!
It is because of the phrase you said in the comment before I made you:
“So what! Weather is weather, and climate is climate.”
And I meant that long-term weather forecasting studies, which were instituted by Barry Saltzman, are alien to the chaotic determinism of short-term (10-15 day) weather forecasts.
That this is based on a property that is very clear and experimentally proven in quantum physics, that the change in scale (from the quantum scale to our macro scale in which humans normally move) causes a different physics. That is to say:
In the most normal day-to-day life of humans, Newtonian physics prevails, however, on the quantum scale, the laws that predict what happens with subatomic particles are very different and it is called quantum mechanics.
This ability is well proven in particle physics ….. but what about the climate?
Your phrase seemed to me to imply that you assumed this difference in the climate … and that therefore you understood its experimental basis …
I was asking you about it and I wanted to know your opinion!
Thanks for your patience and thanks to the whole group !!
¡Buenas tardes Adelaida!
You have overestimated my knowledge by dimensions.
And as I wrote:
” So what! Weather is weather, and climate is climate. ”
I must confess that it was less my personal meaning than what most people say.
To be honest, I intuitively rather think that weather and climate are two highly intricated phenomena, for which a clear separation is illusory.
The transition between the two depends on the spatiotemporal scale within which we observe them, and is probably not quite deterministic, he he.
J.-P. D.
binny…”And as I wrote:
So what! Weather is weather, and climate is climate. ”
As Tony Heller so insightfully put it, there is no concise definition of climate anywhere in science. Climate is far to complex to be defined and far too variable.
When people talk about climate change, they are talking through their hats.
Gordon Robertson
I think it is you who “talk through your hat”. You always follow a contrarian without thinking on your own.
Climate is actually well defined and relatively stable. Evidence by the type of life sustained in a given climate.
http://www.physicalgeography.net/fundamentals/7v.html
Seems different climates are very well defined and this article gives actual data on types of climates. Climate is not “far to variable” at all. If such were the case the types of life would not persist in the climate regions. I think you need to take a breather from contrarian thought and actually used some rational logic. A little thinking might help.
Climate change would be a case where a persistent region’s temperature and precipitation patterns altered in a long term change. If the Pacific Northwest no longer had the precipitation patterns and it dried up. After a few years you would no longer see dense forests. If much greater rainfalls took place in deserts of Arizona or Nevada you would get a much different ecosystem.
Wow, great analysis. Makes sense, and correctly isolating/ removing UHE would also seem to bridge the gap a bit between the sorts of temperature trends being recorded by Satellites and what *should be reported by land stations.
As an aside, the New York Times has retracted their false story about Capitol Officer Brian Sicknick’s death. He was NOT struck in the head with a fire extinguisher. Apparently, he wasn’t hit in the head at all.
Stephen Paul Anderson
It seems at this time the cause of his death is not known to the Public.
https://www.foxnews.com/us/capitol-riot-brian-sicknick-death-investigation-no-charges-autopsy-results-pending
As it is uncertain we will have to wait on this one before making conclusions. Someone was hit by a fire extinguisher however.
https://www.washingtonpost.com/video/politics/video-shows-rioter-throw-fire-extinguisher-at-police-during-capitol-attack/2021/01/14/1e75a543-7c61-43f2-a710-37edde925c0f_video.html
Norman,
So that is supposed to be evidence of someone throwing a fire extinguisher at the police?
Stephen Paul Anderson
That was not supposed evidence. It was real evidence. Someone in the crowd threw a fire extinguisher and hit a police officer in the head with it. The person hit may not have been Sicknick, that is what might have been wrongly assumed. However it is not supposed evidence, it is real.
You do realize that is a fake photo?
Stephen Paul Anderson
Do you realize it is a video and not a photo? You would have to alter the entire video to make a fake. Not saying it can’t be done, if you believe the video is fake provide valid supporting evidence. Just saying it is fake is not an intelligent response. Support your claims with evidence. Demonstrate the video is a fake using evidence.
It looks fake, but maybe it isn’t. I don’t trust a lot of these photos and videos. Many of them are fake (doctored).
WTF has this got to do with the UHI effect?
MJ,
None of your business. Pull your head in.
Thanks for your explanation …..cretin.
They are now blaming the riot on climate change, caused by Trump.
Who are “they,” and where can I see this?
You have no sense of humor.
A typical angry leftist.
Also, no sense.
But you already knew that.
Oh, that was humour, was it? It was hard to tell because it wasn’t funny. Maybe if hyperbole was something you didnt always engage in…
stephen…”New York Times has retracted their false story about Capitol Officer Brian Sicknicks death…”
Thanks for news. It’s beginning to look like a witch hunt. No one seems to know why the guy died even though it’s horrible that he was killed.
From the little I know of the White House altercation, I see no evidence of a riot. Civil disobedience, maybe, but riot, no. I saw far too many real riots in cities like Seattle and Portland, where property was damaged, people were murdered, and police were assaulted. It was disturbing to see Democrats supporting the riots.
All I can make of the White House incident is a protect gone wrong.
Spoken like a true denier.
MJ,
WTF are you talking about? Who cares what you think?
Spoken like a truculent teenager.
Scientists do not use “denier,” but propagandists do.
MJ,
And?
It was a riot. It just wasn’t a socialist riot where capital destruction is the object.
Trump isn’t at any more fault than any other political riot being some politicians fault.
I am sure I couldn’t count the number of flyers I have received from politicians and NGOs imploring that I join the fight.
Normand,
Of course,
for our human time scale the climate is very stable and well defined … but when it comes to computer modeling with the aim of predicting changes in the near future, especially at levels as small as a few degrees of temperature, in the middle of those immense scales of time and space!!!
Shouldn’t it make more sense to consider climate as a chaotic process with extreme scales of space and time … but ultimately intrinsically dependent on the initial parameters and the exact knowledge of how each and every one of these values influence in order to be able to quantify it …..?
Are these parameters well known? … Its assessment within the models is in many cases not approximate and depends on an incomplete current knowledge? (case sun-cosmic rays … to give an example …)
Thank you by your answer Bindidon!!:)
” it make more sense to consider climate as a chaotic process”
Look at a graph of Phanerozoic global temperatures ( the last 700 million years) and you become aware of five strange attractors spaced about 5C apart.
Hothouse 24C
Greenhouse 19C
Icehouse 14C
Severe Icehouse 9C
Snowball 4C
We were in Icehouse conditions during the Holocene and are now rising out of the Icehouse. Having risen from 13.8C to 15C it will be interesting to see when we tip over into the Greenhouse strange attractor. 2.5 C warming would put us halfway to the Greenhouse, call it 16.3C. At current warming rates we might tip as early as 2085.
So far my discussion points about noise in the BOM Australian raw, pristine data has been about “first inspection” errors from transcription etc., errors that can be seen before processing under program.
By far the biggest and most common perturbation of these temperatures is from water, as in rainfall, evaporation, flood etc. Put simply, water cools. Here are some papers by colleague Dr Bill Johnston that deals with water:
https://www.bomwatch.com.au/bureau-of-meterology/are-australias-automatic-weather-stations-any-good/
There are more stations analysed in detail on the bomwatch web site. Broadly, inclusion of annual rainfall figures into multiple linear regression methods commonly shows that some tens of % of the temperature variance can be statistically attributed to rainfall variation. Further noise comes from changes to instruments, glass or electronic thermometers, housings, as in different screen volumes, shapes, effective heights above ground and so on. These are detected by break point analysis and corrected for.
Then using rainfall as a correction factor, a reconstructed temperature time series can be made with corrections for these noise sources, to obtain a “naked” temperature/time series on raw data. This is little different in concept to adjusting data to allow for UHI effects. It is all standard methodology and it gives rather useful outcomes. One day I shall take those 44 pristine Australian stations through the procedures, but it is tedious work on a home PC. It amazes me that the paid professionals with supercomputers have not been responsible enough to do this out of scientific rigor.
Those who comment here that one can obtain high accuracy by averaging large numbers of readings might benefit from going back to the text books to determine if it is proper to use Central Limit Theorem and Law of Large Numbers on data like these. See if you have a sequence of independent, identically distributed (IID) random variables. I say you do not. You have temperature data that can vary from one station to the next because one has an automatic lawn watering system and the other does not. That is not independence in your data.
Nor are two stations independent when one has a UHI effect and the next one does not. Sorry, you are looking at errors, not mathematical ways to reduce them. Geoff S
“One day I shall take those 44 pristine Australian stations through the procedures, but it is tedious work on a home PC.”
Only 44 stations? And only using annual data? Tedious?
It should be easy unless your PC is actually a hand-held calculator.
Rather, I suspect either laziness or a failure to come up with the answers you want.
studentb,
Send me your email address and I’ll send you the starting data. Why not compute it for me?
You do not seem to understand what this next round of calculations entails. Geoff S
Better still. What If I tell you what to do.
First, pick a station. Put the annual rainfall and temperature data into excel columns.
Calculate the linear trends in both series.
Calculate the linear regression (function LINEST) between the 2 data sets and remove the rainfall effect from the temperature series.
Re-calculate the linear trends in the temperature series.
There – simple. Even my cat can use excel.
“Here are some papers by colleague”
A ‘paper’ is a peer-reviewed study. This is not what you colleague has linked. Indeed, he spends one of his blog posts downplaying peer-review. Your colleague has linked to some word documents he typed in.
The headline today is “unprecedented” storm stretches across 25 states. What is it with media today? Everything is unprecedented.
Four million people in Texas without electricity, and frozen wind turbines in Texas, ARE unprecedented. Extremely cold weather is caused by global warming.
As everyone knows, extremely cold weather is caused by global warming. Anything extreme is caused by global warming. The world is going to end in 10 years from global warming. That would REALLY be unprecedented … but there will be no media to report it !
Jennifer Francis was right.
The jet stream is becoming more unstable and the amplitude of Rossby waves is increasing. Hence the present extreme Southerly position of the jet stream over the US and the extreme temperatures in Texas.
https://insideclimatenews.org/news/02022018/cold-weather-polar-vortex-jet-stream-explained-global-warming-arctic-ice-climate-change/
RG said: The world is going to end in 10 years from global warming.
Which publication and which page number from the IPCC does this claim come from?
From climate perfesser Greta “thundering” Thunberg, and climate perfesser Alexandria Occasionally Coherent, (’12 years left’, first stated roughly two years ago).
I forget the page number, but it included a “2”, probably in one of the back-up books — perhaps you can find it? We’ll wait here.
Ok, well, neither name is listed on the IPCC contributor list nor is either a climate expert or even a scientist at all. I can’t imagine why anyone would expect them to be adequate proxies for bona-fide experts or to even speak intelligently on the actual science involved. My advice here is to use your time reading peer reviewed literature on the topic instead of wasting it on trying to parse what they have to say which probably isn’t even remotely close to being right in the first place.
Badwax
You have no appreciation for my “12 years to go” humor comments. I’ll have you know my wife FREQUENTLY compares me with one of the most famous American comedians of all time — Rodney Dangerfield — She often looks at me in the morning and says:”You look like Rodney Dangerfield”.
bdgwx says:
”Ok, well, neither name is listed on the IPCC contributor list nor is either a climate expert or even a scientist at all. ”
They just aren’t listed individually bdgwx. they are listed by association under the category of ”nations”. While this has no scientific reference within the IPCC works it is manifested in the interpretation, selection, consensus, summary, and conclusions.
Beyond that there is a lot of good science within the science bibliography of the IPCC workpapers. All that confabulating though isn’t science its policy.
Thats also why the process isn’t fraudulent. One who confabulates isn’t lying. Instead they are just prone to error.
bill,
By that definition I would be considered a contributor. Except…I definitely am not a contributor.

I didn’t say you were a contributor.
I was talking about political influence in the system and I don’t even know how you vote. I can simply surmise that your posts here don’t amount to any significant political influence.
You definitely nailed my political persuasion…about as close to zero as you can get. I dislike politics with a passion. That is applied equally regardless of whether it is “left”, “right”, Republican, Democrat, or even Independent. My loathing for politics is universal and complete.
One should face it. Identifying with a political party is an excuse to not think for yourself. If you think for yourself a political party isn’t useful. . . .unless you are on the take.
bill,
There is common ground between us. I agree with you on the MOD500 vs GRUMP criticism and I agree with you on the politics thing. 2 in one blog post isn’t bad at all!
Oh, come on BGDWX, do you have your head up your butt?
https://www.theguardian.com/environment/2018/oct/08/global-warming-must-not-exceed-15c-warns-landmark-un-report
It’s already too late.
The CO2 already released has baked in more than 1.5C. We are currently at 1.2C above preindustrial.
Even if we stopped emitting CO2 tomorrow, in 25 years we will have exceeded 5.35ln(411/280)3/3.7 = 1.66C.
I actually read IPCC SR15 report. No where in the report is there any mention of the world ending in 12 years, 10 years, or 100, 1000, or even 100000 for that matter. In fact, even just the word “catastrophe” or similar variations makes no appearance in the summary for policy makers at all. And of the 2 appearances in the text of the full report the word is used in the context that that an increased risk of damage by hurricanes, droughts, flooding, etc. would qualify as “catastrophic”. There is absolutely no mention whatsoever that humanity will die off or that the Earth will come to end.
Now if your beef is actually with the rhetoric The Guardian uses to portray the IPCC report then I share your frustration. I very much repudiate the media’s hype on the topic. Their insistence on insinuating that every weather event is the result of climate change is beyond maddening. Let me spell this out in no uncertain terms so there is no mistake on my position…climate change is NOT alarming. But don’t hear what I didn’t say. I didn’t say there won’t be consequences. I didn’t say that sea level rise, reduced crop yields, etc. are not a concern. But to sensible people those things are not cause for “alarm” in the context the word is used by contrarians.
So you’re saying the Guardian are a bunch of liars, and anytime one of your brethren links them here, you will speak out against it?
If anyone makes a claim that isn’t supported by science then I will definitely speak up. That applies equally to Al Gore, Greta Thunberg, AOC, The Guardian, or whoever else wants to misrepresent the science with flashy headlines or unsupported claims.
BTW and FWIW…The Guardian did not say the world would end anytime soon. And yet I still feel obligated to repudiate their rhetoric. If that doesn’t make my position on the matter crystal clear than I don’t know what will.
Stephen.
Imagine that I publish a spoof paper describing the effect of leprechauns on climate change, including the most likely outcome, 0C change, and 95% confidence limits of +/-1C.
How a newspaper reports the paper depends on its editorial policy.
The Guardian tends to focus on the highest figure.
“Leprechauns warm the world by 1C.”
Th Daily Mail tends to focus on the lowest value.
” Leprechauns cool the world by 1C. ”
Best to get your information directly from the scientific papers rather than the newspapers.
EM,
Exactly. And the context in which the word “catastrophe” was used by the IPCC wasn’t the same context that The Guardian was trying to imply. Nevermind that the 2nd use of the term by the IPPC appeared in a box with the label “Scenario 3 [one possible storyline among worst-case scenarios]”. So not only was it a worst-case scenario, but it wasn’t delivered with the same “alarmism” that The Guardian tried to insinuate. Like you said…it’s better to just read the scientific papers directly then having the media interpret them for you.
But they weren’t saying that without context. They said, according to the UN. You know, the IPCC people.
I don’t see many IPCC people clamoring loudly after The Guardian, and others report such nonsense. That’s the point. The IPCC needs to shut them down, not us “deniers.”
I agree with you on that. The scientific community needs to step up and combat extreme rhetoric on both ends of the spectrum.
Winters like these should act as a warning that we do not have a global warming problem. We have a global cooling problem. If the planet starts cooling significantly at some point, we are screwed.
One the basic problems I see with the multi-layered climate model is the night and day problem.
Science is silent on how heat trapped at TOA gets back to the surface. That is an obvious obfuscation as one cannot surmise a multi-layered theory on the basis of ”some how” with no official expressed theory.
And here is the probably the reason, IMO, something hasn’t been surmised at least publicly (beyond the obvious need to encode the processes in someway in models if the models are just simply parameterized to avoid the physics problem)
Basically the only logical method would be via restriction of convection. But convection is primarily a daytime phenomena that would feature higher Tmax temperatures with less impact on Tmin temperatures.
But when we look at the rare Tmin/Tmax graph what do we see? Twice the effect of global warming on Tmin than Tmax. Then the Guardian jumps in to talk about massive Tmax effects. Its all so illogical and ignorantly discussed. Fact is the ”assumptions” about the CO2 greenhouse effect seem to override common sense. Must not be much running around or skepticism would be an order of magnitude higher.
Literally the first sentence in the article:
“The worlds leading climate scientists have warned there is only a dozen years for global warming to be kept to a maximum of 1.5C”
What is meant here is that if we don’t reduce emissions in the next decade we will be locked in for 1.5C of warming by 2100.
This is super simple stuff you’re messing up here.
Four million people in Texas without electricity, and frozen wind turbines in Texas, ARE unprecedented. Extremely cold weather is caused by global warming.
China will never power their tanks with Solar, Russia will never fly their bombers using wind, rockets will never be powered by geothermal. China, Russia and our enemies are laughing at us.
Biden blocks pipelines in the US, support them overseas. Hunter helps Russia, Ukraine and China build energy projects, while Daddy Joe blocks energy projects here in the US. Most concerning of them all is that Joe Biden supports nuclear power and ultimately a nuclear bomb for Iran, while blocking Nuclear Power in the US. Why would anyone want Iran to be a nuclear power? I can only think of one reason, and it is horrific.
“Four million people in Texas without electricity, and frozen wind turbines in Texas, ARE unprecedented. Extremely cold weather is caused by global warming. ”
Indeed. I think of human activity as the cause, global warming as the effect and climate change as the consequences.
Climate change is not just about warming, it is about changing the way the climate behaves. The shape of the frequency distribution of the temperature data is changing. The global mean is increasing, so is the standard deviation. The frequency of both extreme heat and extreme cold is increasing.
Effects include unusual heat waves in India and unusual cold elsewhere. The unusual cold at present in Texas and Greece are present examples, caused by the jet stream at both locations moving unusually far South and bringing Arctic air with it.
You may remember that increased variability in the movement of the NH polar jet stream was predicted by Jennifer Francis in 2013. The southerly net stream currently chilling Texas is not proof of her hypothesis, but it is consistent with it.
https://insideclimatenews.org/news/02022018/cold-weather-polar-vortex-jet-stream-explained-global-warming-arctic-ice-climate-change/
ET Says: Climate change is not just about warming, it is about changing the way the climate behaves.
By what possible mechanism can man increasing CO2 cause cooling? The physics are very very very simple. Increase CO2 increase W/M^2 at a log decay rate. How can you cool something by adding energy to the system.
All this CO2 and AGW is pure nonsense. CO2 has been as high as 7,000 ppm and there was no catastrophic warming.
I’ve posted 265 stations that show no warming, even though CO2 has increased by 30 or more %. There is infinitely more evidence that CO2 isn’t causing warming than that it does. Doctored data doesn’t count as evidence.

Entropic Man’s comment. LMAO!
I didn’t say what is causing the warming, nor does it matter in this context.I’m just describing one of the secondary effects of warming.
Observation shows that the Northern Hemisphere is warming and that the Arctic is warming faster than temperate latitudes.This is reducing the strength of the jet stream, which is stronger when the temperature gradient is larger.
Like a river, a weaker let stream meanders more, bringing Arctisc air further South. This used to be rare, but excursions like the current cold snaps in Greece and Texas are expected to become more frequent.
Entropic man
” … but excursions like the current cold snaps in Greece and Texas are expected to become more frequent. ”
Maybe!
But… please look at e.g. the night temperatures the Greek location Larisa experienced during the last weeks:
https://tinyurl.com/zk7av3ek
and compare them with a sort of Larisa’s February history in GHCN daily since the 1950’s:
GR000016648 51-80 2004 2 14 -12.0
GR000016648 51-80 1963 2 1 -10.5
GR000016648 51-80 1991 2 3 -10.2
GR000016648 51-80 1956 2 9 -9.5

GR000016648 51-80 1960 2 4 -9.0
GR000016648 51-80 1975 2 10 -8.6
No doubt that there was a sudden stratospheric warming, possibly due to the weakening of the polar vortex, and that it affected lots of places in Europe!
But colder temperatures than now happened lots of times in Greece already.

Looks as though the Greek chill is much less severe than the Texas cold snap.
I was just watching a report on the Texas weather in the BBC. It was noticeable that the local infrastructure is not designed to cope with extreme cold.
Power outages, party because the wind farms froze up.
Most houses were uninsulated, which made them very difficult to heat.
No attempt had been made to clear snow off the roads, perhaps for lack of suitable machinery. Lots of crashes because nobody had experience of driving in snow.
People have asked what the optimum global temperature should be. The planet probably doesn’t have one, but communities do. The Texas infrastructure has been designed to handle heat, and the current conditions are outside their design envelope.
As time goes on many more communities are going to encounter conditions that their infrastructure is not designed for. Too hot, too cold, too wet, too dry or too windy.
Entropic man
I just looked at my weather web site, and discovered this:
https://images.ctfassets.net/4ivszygz9914/83fe1bce-2c73-4ceb-a1e4-9dfcae3b78df/5319c75ad0fb4a9f347525d09bb6a13f/a89d1897-d07c-48cd-86b3-47095a03be0b.png
Looks quite heavy…
Polar vortex weakening seems to have much more radical consequences in CONUS than in Europe.
J.-P. D.
Perhaps because CONUS is a large enough continent to contain an entire Rossby wave without disruption.
I don’t know why, but this pattern seems to recur, with the wave stabilising down the centre of the continent.
Someone with more meteorology might speculate on coastal effects, or the presence of two North/South mountain ranges, the Rockies and the Appalacians on the Western and Eastern sides.
The main mountains in Europe are the Alps and their extensions, running East-West.There is also a coast to the West, but only land to the East. Do N/S mountain ranges and coasts tend to hold a Rossby wave in place?
The frozen wind turbines in Texas are only 13% of the outages.
The rest are failures at natural gas, coal and even nuclear plants.
Iowa is pretty cold, as well as Illinois, and wind turbines there can work in winter, I wonder why Texas is so fouled up.
Maybe there electrical grid being by itself and deregulated is the main reason.
They should build there infrastructure to be able to withstand a little cold weather.
“They should build there infrastructure to be able to withstand a little cold weather.”
Cold weather adapted infrastructure costs, as does heat adapted infrastructure. It is uneconomic to build everything to tolerate every possible contingency, so you optimise for your normal range of conditions plus a bit of margin and accept that you will see occasional disruptive extremes.
A full suite of snow clearing equipment might cost $20 million.
Chicago airport would use that every week during the Winter, Houston airport might use it once a decade.Similarly Illinois maintains a pool of equipment to keep the roads clear which would be uneconomic in Texas.
Ditto with houses. My 1930s built house in Ireland is designed for temperatures between 5C and 25C. Even with modern insulation it is hard to keep warm in freezing weather and uncomfortable in hot Summer weather.
This will be the same for any house. In Houston, house features which make it comfortable in Summer heat make it difficult to live in in the cold.
A house which is comfortable both in -10C and 30C would be very expensive and contain a lot of features and equipment which would be rarely used.The
One of the problems with climate change is that in many regions the normal range is drifting, making the existing infrastructure obsolete. Due to increasing sea level Miami Beach is raising roads on embankments, installing drainage pumps to protect high value properties and will have to abandon whole neighbourhoods which now flood regularly.

You wrote upthread:
” … the sorts of temperature trends being recorded by Satellites… ”
1. You very certainly did not mean ‘satellites’ here.
You very probably meant ‘UAH’s evaluation of satellite data’ instead.
Simply because for RSS4.0 LT and NOAA STAR, the evaluations give higher trends, unacceptable to ‘Skeptic’s:
1.1 LT: UAH6.0 vs. RSS4.0
https://drive.google.com/file/d/1Xnvq5KqYbroDtjGkl1wq7kL5hEu6Giz8/view
1.2 MT: UAH6.0 vs. NOAA STAR
https://drive.google.com/file/d/1wP_BVntz4YFoV3uUDpJAdhwQsCVLhBSa/view
Since many here think I’m an alarmist, I have fun in playing this role, and say, so to speak “the other way around”:
UAH makes everywhere the past warmer and the present cooler, ha ha.
*
2. The origin of the gap, if any, is not ” what should be reported by land stations “.
It is rather the overall evaluation of the data they report.
For example, the global evaluation made by Japan’s Met Agency is, with a trend of 0.14 C for 1979-2020, identical to UAH’s:
https://drive.google.com/file/d/1VCFyZQZVc0ZjVqHqux-lNAPbAIrgpk5A/view
*
At the cost, of course, of a lack of interpolation helping in filling at least a part of the unknown.
Not doing this automatically means that all unknown places will have the same temperature and the same trend as the global mean.
Of all the people boasting that infilling is by definition something wrong (if not even fraudulent, hear hear) not one would ever be able to provide for a proof for their claim.
Not one of them!
Infilling using interpolation (mainly kriging) is used in several disciplines (mining, highway design, even medical research) without any complain from anybody.
Anybody having experience in software development and V&V knows that such a task is tested by removing known data and comparing its ‘ersatz’ thru infilling with the original.
But, ooooh… here, CO2’s shadow and fossile fuel lobbyism make everything different.

“Infilling using interpolation (mainly kriging) is used in several disciplines (mining, highway design, even medical research) without any complain from anybody.”
Beeen there, done that.
You miss a vital difference.
Those applications use those statistical methods primarily to estimate uncertainty. For mineral resources, for instance, we used them to put uncertainty limits around our estimates of grade and tonnes to be mined, so the bankers could see how much they would risk if the lower estimates turned out correct. The decision to mine (and I was involved in this several times) is mostly made on the results of drill hole assays, not on the interpolations, because they commonly contain subjectivity.
Also, in mining, after the deposit is mined out, one calculates tonnes and grades actually mined, to reconcile with pre-mining estimates. This allows continuining refinement of the methods.
You should not place much weight on interpolations when you cannot complete this reconciliation. Like, you cannot with infilled sea surface temperatures.
Interploated results should not be used to influence public policy.
Interploations are guesses. You should not try to place credibility on the statistics of guesses, when real data are available, for there is no standard text about statistics of guesses that can help this work. Geoff S
Geoff Sherrington
Thanks for your convenient reply.
1. You seem to have made experiences differing a lot from what I learned through discussions with French engineers long time ago.
2. No I did not miss any vital point, please believe me.
3. But conversely, I miss from your side a valuable estimate for what is better:
– uncertainty through use of infilling
– certainty of doing wrong when you don’t use it, for the reason I clearly indicated above.
4. Whom do you think shall I trust more?

Bindidon.
You were not to know this, but in the 1970 our exploration company deliberately involved ourselves in the emerging methods of geostatistics. We sent people from my offices to France for months at a time and brought French people to Head Office in Sydney for lengthy stays. We applied the methods to the estimation of grade and tonnes in the major uranium deposits of Ranger One, Numbers 1 and 3 orebodies. We later did a reconciliation which showed the calculations to be more than adequate. It is possible that after the French themselves, Matheron, Journel, Krige, Sichel and others at Fontainebleau. We immersed ourselves in the methods quite instensely for several years and I was fortunate to have some rub off on me.
All this before Kevin Cowtan was out of short pants.
Keep your rude comments to yourself, please. Geoff S
Geoff,
So how would you go about computing the mean from a 2D scalar field and quantifying the uncertainty? Can you post a link to a dataset that publishes a global mean temperature that uses a method you feel is adequate?
bdgwx,
My preference is to direct my research along lines that I like, not to slavishly try to fit my thoughts into the crowded mind space of others with various competencies. I have no interest in a historic global mean temperature because the data available to contribute to it are not fit for that purpose. Geoff S
Climate scientists definitely have an interest in constraining the range of the global mean temperature at various moments in time. If you can’t offer a better method or constrain the temperature any further then I guess I have no choice but to rely on the evidence that is currently available.
the common person without propaganda influencing him simply isn’t concerned about global mean temperature if its in the delta range of 1 to 5c.
I mean I can live just as well in Costa Rica at a mean 27C as I can in Seattle where its below 11C.
And trends in global mean temperature don’t seem relevant to much when looked at over periods of time where various regions at similar latitudes aren’t consistent with each other. Such longterm regional variation when at greater differences than the global trend is indicative of internal variation such as oceanic overturning and the geographic features of the earth that would cause thermometers in different places to both vary and vary over different time scales.
This observation was made by a celebrated atmosphere physicist over a decade ago, Dr. Syun Akasofu, yet sycophants love to latch on to small tidbits of largely meaningless prattle to come to sweeping conclusions about the future of the earth.
All this cold weather has me wondering how we could tell the Holocene interglacial period is ended. How long would it then take the ice to return to being a mile thick over Toronto?
Ken
I open the bet
10,000 years.
J.-P. D.
For the last 2 million years we have alternated between icehouse conditions around 14C and severe icehouse conditions around 9C.
Until we started interfering the cooling trend was -1.2C over the last 5000 years. That would bring us back to 9C and full severe icehouse conditions in another 16,000 years.
There are feedbacks such as increasing ice albedo which accelerate the cooling, so that 16,000 years is probably longer than it would actually take.
We’ll probably never know now. Our extra CO2 will prevent an imminent severe icehouse. It is estimated that it will take at least 40,000 years for natural processes to remove it.
Ent, perhaps you could explain why the geological data temperature goes up then CO2 goes up lagging temperature by about 800 years and then the temperature drops precipitously and this appears to happen cyclically. If your hypothesis about CO2 preventing the return of severe icehouse conditions were right wouldn’t the data be showing something else? Or does too much CO2 in the atmosphere trigger a severe icehouse event?
This is an old denialist meme, that temperature change always precedes and causes CO2 change and therefore that modern CO2 release cannot cause temperature change.A logical fallacy.
CO2 and temperature form a feedback loop.If temperature changes, CO2 follows. If CO2 changes, temperature follows.
There are temperature sensitive carbon sinks like the oceans, permafrost and peat bogs.
When something naturally increases temperature the sinks release CO2 into the atmosphere and the increased greenhouse effect amplifies the temperature change.
When something naturally decreases temperature the sinks take up CO2 and the reduced greenhouse effect amplifies the cooling trend.
CO2 follows temperature.
The reverse also happens. A natural increase in CO2 such as a shield volcano causes temperatures to increase. When the excess CO2 is removed temperatures drop again.
700 million years ago weathering reduced CO2 to the point where temperatures dropped enough to allow global glaciation and a snowball Earth. It took millions of years of volcanic activity to increase enough CO2 for temperatures to begin rising.
Temperature follows CO2.
Think of humanity as an artificial shield volcano. We have released enough CO2 to increase concentrations by 40% and temperatures are following CO2.
Ken,
The claim that CO2 lags temperature is for the glacial cycles.
And this claim is actually a bit more nuanced than the bloggers want you to believe. It has been shown that CO2 lags in the SH, but leads in the NH. See Shaken et al. 2012 for details.
CO2 leads the temperature when it plays the role forcing first and feedback second. It lags when it plays the role as feedback first and forcing second. Or in other words, it leads when it catalyzes the temperature change and lags when another agent catalyzes the temperature change.
There have been periods in Earth’s past where CO2 has both lead and lag. The glacial cycles would be an example where a lagging behavior has been observed (though as I said above this is rather nuanced). But the PETM, ETMx, and other events would be examples where a leading behavior has been observed.
In a nutshell…CO2 leads when a non-temperature related event causes it to be released into the atmosphere. It lags when it gets into the atmosphere because of temperature related feedbacks.
The glacial/interglacial cycle is driven by changes in the Earth’s orbit.
This changes the amount of sunlight reaching high Northern latitudes. Reduced sunlight allows snow to persist through Summer and build into ice sheets which reflect even more sunlight. Reducing temperatures cause sinks to take up CO2 amplifying the cooling.Earth cools into a glacial period.
Increasing sunlight reverses the process and Earth warms into an interglacial like the present.Under current geological and astronomic conditions one cycle takes about 100,000 years with interglacials lasting on average 10,000 years.
For more detail research Milankovich Cycles.
We are in what would naturally be the end of the Holocene interglacial. Temperatures drifted gradually downwards by 1.2C in the last 5000 years, with CO2 expected to follow.
Then the Industrial Revolution happened. We have released enough CO2 to reverse the natural cooling trend and extend the Holocene interglacial indefinately.
40,000 years is just a fake scare figure. Removal of anthropogenic CO2 is a logarithmic function with most being removed in about 40 years. Indeed there is a long tail of very low levels of reduction that would extend out longer.
Ken
This is global temperatures for the last 800,000 years.

EM,
Why have you not learned that it is not correct to pin recent thermometer data on the end of old proxy data? Why Mann was chastised correctly for making a hockey stock this way? Why you then add pure speculation in the form of guesswork by IPCC? This is wrong on too many counts. Geoff S
Geoff Sherrington
Sorry, you are certainly honest in your evaluation, but undoubtedly you are a victim of a big manipulation, too.
Mann wasn’t ‘chastised’ for ‘old proxy data’.
1. Ross McKitrick unqualifiedly denied the correctness of his use of Primary Component Analysis as statistical method;
2. Steve McIntyre’s claims against the mix of proxies and temperatures were, over time, reduced down to… dendrochronology using a few pine samples.
3. At least 9 studies confirmed Mann’s work.
4. In 1998, the attacks against the stupid hockey stick were IMHO due to the fact that no one had ever seen a temperature time series of that size.
Please look e.g. at Pages2K 0-2000:
https://drive.google.com/file/d/1QNmA5_rTVCHEOCo87TcPvmuB2GO_jiSV/view
and at a comparison since 1850 with Had-CRUT4, and since 1979 with UAH6.0 LT data:

5. In addition, lots of people, convinced about the fact that MWP was everywhere on Earth, missed on all such plots the peak they had expected.
J.-P. D.
Bindidion: At least 9 studies confirmed Manns work.
That is an absurd joke.
1) No independent study would ever implement the completely custom “Mike’s Nature Trick to Hide the Decline.” That is fraud.
2) No credible temperature reconstruction would ever produce a Dog-Leg specifically in 1902 and 1980 when the construction methodology changes.
3) The Dog-Legs are not supported by physics
4) Individual station data controlled for UHI and Water Vapor you find no warming at all
5) 70% of the earth is water, that temperature record contridicts the Hockeystick
6) Sea levels and other climate data don’t show confirming Dog-Legs in 1902, it is a pure hoax
CO2isLife
Stop your stoopid fraud claims. We are on a science blog here, and not at your loved breitbart corner.
1. For your afflicting dog-leg trauma, please visit a psychiatrist.
2. You have beeen shown many times that your trials to link CO2’s activity to surface temperatures are absolute nonsense. CO2’s activity is located above the tropopause.
3. I have shown to you that the average over 130 desert stations, including the Antarctic, has very well a trend, which moreover is higher than the average over all stations located in the tropical regions saturated with water vapor.
When will you finally stop boring us with your stubborn, prepubescent garbage?
J.-P. D.
Up the road from me is one of the Dupont nylon plants.
It is liberally covered with temperature sensors. In its early days you climbed ladders with a clipboard to record temperatures directly from a mix of alcohol thermometers, mercury thermometers, and bimetallic strips.
Gradually they began to use electrical sensors and now they are in their third generation of thermistors and radiation sensors, reading directly into a central computer.
They use this data to calculate fatigue lives for the reactors, so the continuous record is safety critical, but noone has ever suggested the the temperature/time series generated by one set of instruments could not be connected to the next.
Geoff said: Why have you not learned that it is not correct to pin recent thermometer data on the end of old proxy data?
How would you relate the proxy temperature record to the instrumental temperature? Can you point us to a publication that describes an alternate method that you feel is acceptable?
There is very little proxy data that is reliable over less than 100 year periods. . . .that was the reason for excessive reliance on dendrochronology with cherry picked trees.
Earlier I have provided what should be useful information about the correction of ground temperature data for UHI.
My meteorologist colleague Dr Bill Johnston has a blog site that is much more useful to describe the processes required to clean up such data to make it useful in UHI studies. This is for Australian data, which has fewer historic complications than USA, for example TOBS. However, Bill has developed an excellent approach using rainfall to correct for step changes that are all too often not associated with well-recorded metadata.
Look for stations Rutherglen, Cape Leeuwin, Amberley and soon-to-be-released Charleville, Queensland. Geoff S
https://www.bomwatch.com.au/category/bill-johnston/
Yeah, I recall lots of info provided by Bill Johnston, e.g.
https://jennifermarohasy.com/2014/09/rutherglen-still-looking-for-answers/
J.-P. D.
A major problem with the approach proposed by Geoff Sherrington for adjusting Australian temperature data is this:
decreasing rainfall can be expected to have a positive effect on temperatures while increasing rainfall can be expected to have a negative effect.
The thing is that much of western and north-western Australia has been getting wetter. Therefore, temperature trends there will have been suppressed. i.e. any corrections taking account of rainfall will result in an increase in background warming trends.
Cherry picking stations where rainfall has decreased, such as Cape Leeuwin, will only distort your results.
Student,
Thank you for turning a genuine scientific effort into a sneer exercise. Your comments are wrong in so many places that one might conclude that you did not comprehend the methodology.
What did you hope to gain from this ignorant negativity, when a reasonable, normal scientist would enjoy new material with potential to advance understanding?
Geoff S
“a genuine scientific effort” ?
Give me a break! This is pure, armchair, amateurism that would never pass peer review in a million years!
studentb,
sounding more like studentc,
or studentf
Wild guess speculation about climate doom 50 to 100 years in the future passes peer review too.
Peer review is pal review — it enforces the current consensus, which usually turns out to be wrong — from slightly wrong, to completely wrong. Science is never settled. If it was, we would need far fewer scientists.
Noah Diffenbaugh: WE HAVEN’T HAD ENOUGH WARMING TO ELIMINATE COLD EVENTS
And?
The overall GW on Land is ~ 2 degrees F on average.
In winters, a cold air mass comes through and drops temps by 40 deg F. The 2 degrees added to the global average wont make much of a difference to that.
But the much warmer Arctic MAY change regional weather patterns, via the Jet Stream. That can potentially be a much larger effect.
Indeed often one needs to get really ”imaginative” to come up with excuses.
The fact is that the stratospheric jet stream that holds the arctic air in place, in the Arctic, has quite complex behavior, and itseems to be changing, just as the Arctic is rapidly warming.
Science is about finding out why things are happening.
You wanna call that finding excuses…whatever you say.
The problem is as I pointed out above the politics is spending huge sums of money to try to think about what a warmer climate brings and not about what was a common occurance a few decades ago.
When I was a youth the jet stream dipping down into Texas and Florida was a more common occurrence. What may be primarily decadal climate variation is the most likely culprit here and a lot of loud mouths who think they know something.
“the most likely culprit”
So now you understand the science of the jet stream wandering enough to be confident that Arctic warming has no effect on it?
While the actual scientists are not certain about it.
Typical Bill.
Nate you should learn to read with better comprehension.
I didn’t say a warmer arctic or anything else was responsible. I merely pointed out that in the 1950’s and 60’s the jet stream dipping into Florida and Texas was a more common event than it has been recently. BTW, the arctic was colder then.
You can draw your own conclusions and I have no doubt that you will in doing so will don some horse blinders to see only what you want to see.
” I merely pointed out that in the 1950’s and 60’s the jet stream dipping into Florida and Texas was a more common event”
We know that overall CONUS was colder in the 60s and 70s.
I don’t think we know that the kinds of events that just happened in Texas were more common. Unless you have some data on that?
Here is the Arctic vs other regions. The Arctic has warmed faster than the Tropics or Mid latitudes.
http://www.columbia.edu/~mhs119/Temperature/T_moreFigs/zonalT.png
I asked our resident Meteorologist, Roy, awhile back whether this change in the N-S gradient could be expected to change weather patterns in CONUS. He answered with unequivocal YES
Your confidence that “decadal climate variation is the most likely culprit here” is not science based opinion.
“The problem is as I pointed out above the politics is spending…”
When science hasnt found a final answer yet, you seem to think your political biases can give us the answers.
Nope.
Nate says:
”We know that overall CONUS was colder in the 60s and 70s.
I dont think we know that the kinds of events that just happened in Texas were more common. Unless you have some data on that?”
LMAO!!! You mean you didn’t check first before buying the hogwash about this having something to with global warming???!!!!
Boy you bit on that with all the intellectual fortitude of a cod striking a clam with a big hook in it.
Yes this is an unprecedented event but its not unprecedented because of the cold. Fact is in the 50’s few homes had electric or natural gas heat. Most homes had on site storage of fuel in the form of wood burning fireplaces or stoves and/or coal or oil burning furnaces. Plus people tended to have thick wool blankets. Wool blankets became very popular for the native populations especially after the buffalo herds had been thinned down.
What has changed is growing dependence on either governments or corporate/municipal utilities to deliver fuel for heat real time.
The transfer to this dependence has been ongoing for at least 55 years through a combination of subsidies to tract home builders (all electric homes), and via regulation making the population in many ways more vulnerable to disruption.
” You mean you didn’t check” C’mon Bill, we all know that is your standard MO. Ha!
“Fact is in the 50’s few homes had electric or natural gas heat. Most homes had on site storage of fuel.”
Now we’ve subtly moved the goal posts back to the 50s and changed the subject, so that you don’t need to offer evidence to back your original claims.
Standard Bill BS.
Is that the best you can argue Nate. No movement of goal posts.
The temperatures and dipping of the jet stream into Texas and Florida in the 50’s and 60’s was common. People were used to it. You are just stupid.
“The temperatures and dipping of the jet stream into Texas and Florida in the 50’s and 60’s was common.”
Show us evidence.
Otherwise it is just another Bill declaration, ie worthless.
Nate says:
”Show us evidence.
Otherwise it is just another Bill declaration, ie worthless.”
What and educate you? Nah. . . .much more fun having you hold up the fringe lunacy viewpoint around here.
You seem to equate mainstream science with “fringe lunacy”?
That explains the many anti-science themes of your posts.
Nate says:
”You seem to equate mainstream science with “fringe lunacy”?
That explains the many anti-science themes of your posts.”
Right! But its only in your dreams that AGW causes extreme cold events. There is zero science supporting that concept which is held only by fringe lunatics.
” only by fringe lunatics.” OK Bill, whatever you declare…
OK name a top atmosphere physicist that believes extreme cold events are being caused by global warming.

https://www.carbonbrief.org/qa-how-is-arctic-warming-linked-to-polar-vortext-other-extreme-weather
LOL! How predictable a link to a lunatic blog and a science paper whose primary source link is to AR4 on extreme events that reads:
”Temperature Extremes
It is very likely that heat waves will be more intense, more
frequent and longer lasting in a future warmer climate. Cold
episodes are projected to decrease significantly in a future warmer
climate. Almost everywhere, daily minimum temperatures are
projected to increase faster than daily maximum temperatures,
leading to a decrease in diurnal temperature range. Decreases
in frost days are projected to occur almost everywhere in
the middle and high latitudes, with a comparable increase in
growing season length.”
I guess you are the lunatic along with your favorite lunatic blog. Nice Job showing us where you are really coming from Nate.
The point I am making Nate is being responsible for supplying power needs to be contracted on a rational basis not 1 second before the fuel goes into the line. Consumers shouldn’t be abused like that.
I would think rates that changed monthly with a one month notice of change along with some kind of delivery guarantee, which would be both gnarly and politically hot to negotiate as nobody likes assuming liabilities, might have to be mandated legislatively.
What we are looking at is a lot inherent risk that nobody really wants to assume and it lands of the heads of the municipal suppliers and end customers instead. Neither of the those is what free market are about. Free markets are about choice and suitability of those choices for lifestyles. Essential warranties are become more commonplace all the time. Micromanagement seldom works well for several reasons. One is the corruption in the specifications, two is unintended consequences, three is the unforeseen.
Wind power though probably doesn’t want to have buy fuel when the wind doesn’t blow and there is one place the politics at work.
Would someone please explain to me how increasing W/M^2 can possibly cause temperatures to fall to the record levels we are seeing today? We have spend trillions to fight climate change and Texas, one of the most oil rich locations in the world with plenty of access to Coal and Natural Gas and they can’t power their state. That is how totally insane the Green Economy is. BTW, Biden wants a Nuclear Iran, why, certainly not for electric power, what he should be pushing for is a Nuclear Texas.
Why the hyporcicy? Why does Biden want to arm our greatest enemy with a nuclear bomb that doesn’t need energy, and he opposes nuclear and pipelines in America? Why does he want to strengthen our enemies and weaken our Domestic Economy?
Greta was caught turning up the thermostat.
“Would someone please explain to me how increasing W/M^2 can possibly cause temperatures to fall”
We already have. Global warming can cause changes in the behaviour of jetstreams. These in turn can cause local cooling.

… and the very best is that in Texas, one of the most conservative, pro-industrial, pro-fossile corners on Earth, suddenly the “Green Economy” is the origin of all the state’s malheurs.
It would be more sane and more fair to see the problems somewhere else, for example, in the indifference typical of the southern US states.
But that seems to be politically unacceptable.

Funny that Germany has retained all its coal-fired plants. Odd you’re beating the drum for us to eliminate ours.

As usual: simple-minded, polemic blah blah.
I never and never was at any time beating any drum to eliminate any coal plant on Earth.
And above all, Germany did not ‘retain all its coal-fired plants’.
That is typical American alt-right nonsense written by persons ignoring facts.

Thanks again. Germany gets 22% more of its power from coal than the US. All kinds of tidbits.

Again, you behave as a polemic ignorant: you hide the facts that
– your Trump dictator guy has forbidden us to intensify our gas cooperation with Russia;
– Germany has no shale gas, due to the extreme population density.
Luckily it hasn’t!
Your country will have to pay a huge bill in one or two generations.
J.-P. D.
Stephen,
10 y ago, Coal was 33% of US electricity. All you are saying with this stat for the US is that we have gained access to an abundance of new, cheap, natural gas AND renewables in the last 10 y.
While Germany has gained renewables, but not had that easy access to gas.
The larger US has access to relatively more natural resources than Germany.
And…what is your point?
Even with this access to Gas, the US per capita carbon emissions were 16, while Germany was 9.
https://en.wikipedia.org/wiki/List_of_countries_by_carbon_dioxide_emissions_per_capita
Yes Nate per capita consumption in Germany is about 1/3rd less than in the US. Thats what happens when you triple the price of gasoline and put all the burden on the middle class and poor.
“Would someone please explain to me how increasing W/M^2 can possibly cause temperatures to fall to the record levels we are seeing today?”
This has been explained to you many times.
Weather does not stop happening under global warming. The squiggly line will still go up and down for ther global average, and those upsd and downs are much more extreme for local weather.
What should happen in a warming world is that local record-breaking highs should occur more frequently than local record-breaking lows in most if not all years recently.
Guess what?
https://www.mherrera.org/records.htm
https://www.mherrera.org/records1.htm
“We already have. Global warming can cause changes in the behaviour of jetstreams. These, in turn, can cause local cooling.”
Really? Proof of that? CO2 can cause both warming and cooling? That isn’t science, that is superstition. If you think through that insane logic, CO2’s warming would be self-correcting. It would warm, change the jet stream, and cool. Then there is no problem. If CO2 now causes cooling, how are we ever going to get back to warming? Texas is now paying $9,000 MegaWatt, which used to cost $100 at peak demand. That is how insane this unreliable Green Economy is.
Anyway, here are the Facts:
1) Official US Policy is to support and facilitate nuclear power in Iran, a sworn enemy of both the US and Israel.
2) Iran has promised to “wipe Isreal from the map.”
3) The US is helping Iran reach that goal by facilitating the production of a Nuclear Bomb
4) The US policy is to support the Trans-Afganistan Pipeline and Natural Gas Importation of the EU.
5) The US is blocking pipelines in the US and inhibiting production of Natural Gas.
Bottom line is US Policy is to facilitate the arming and strengthening of our enemies and weaken the US.
Texas is a great metaphor for AMerica of the future. They have a huge surplus of energy and can’t keep the lights on. Texas has no execute, they had California and Germany as warnings, and they chose to ignore them.
Once in a while it gets very cold in Texas. So what.
That’s weather in Texas, not climate.
The climate of our planet has been warming since the mid-1970s, but by a small amount. That doesn’t mean Texas will never have a really cold week. We’re having a really cold week here in Michigan too. But our winters in recent years have not been as cold as they were in the 1970s. And that is great news. I hope someday, after more global warming, we will never have a really cold week in Michigan again, and we can retire our snow shovels.
Really cold weather in Texas happened before, in 2011, when 3.2 million people were affected by rolling blackouts. Windmills were not the problem back then — they accounted for only 4% of the total sources of electricity.
A report was written the 2011 incident. In summary, the entire energy infrastructure in Texas was not set up to withstand unusually cold weather. I suppose the report was put on a shelf to collect dust.
So it happened again in 2021 the next time really cold weather hit Texas. But even worse this time, because windmills were up to 25%, from 4%, and roughly half of them froze. The other windmills did well because there were good winds to spin them. A large majority of the problem was from the non-wind energy sectors, just like in 2011.
My brief article on the 2021 and 2011 Texas “incidents”,
posted on my climate science blog yesterday, is at the link below, which includes a link to the official 2011 report:
http://elonionbloggle.blogspot.com/2021/02/weve-had-fun-mocling-frozen-texas.html
We should be fair in our reporting about the Texas windmills — including both the bad news, and the good news:
The bad news:
Half of the Texas windmills froze.
The good news:
Half of the Texas birds were safe.
What a propagandist you are, Richard.
“…wind farms are responsible for roughly 0.27 avian fatalities per gigawatt-hour (GWh) of electricity while nuclear power plants involve 0.6 fatalities per GWh and fossilfueled power stations are responsible for about 9.4 fatalities per GWh. Within the uncertainties of the data used, the estimate means that wind farm-related avian fatalities equated to approximately 46,000 birds in the United States in 2009, but nuclear power plants killed about 460,000 and fossil-fueled power plants 24 million…”

Windmills are bird shredders Nuclear plants are not.
https://www.engineering.com/story/the-realities-of-bird-and-bat-deaths-by-wind-turbines
What a propagandist you are, Richard.
Your article doesn’t compare nuclear to wind power generation and bird mortality. Nuclear kills more. Coal kills more.
“Bird-shredder”
That’s your own language, as you soberly assess the difference in vario- I beg your pardon, I mean- as you pour on the rhetoric to smear wind energy.
If you read the article you get to this paragraph:
“Even with its relatively low impacts, the wind industry holds itself to a higher standard and does more to mitigate wildlife damages than any other energy industry.”
So not only does wind power kill significantly fewer birds per kilowatt hour than fossil fuel sources, the industry also does more to mitigate the issue than fossil fuel industries.
But you wouldn’t learn any of that if we relied on you and you alone for information.
“Your article doesn’t compare nuclear to wind power generation and bird mortality. Nuclear kills more. Coal kills more.”
My response: Barry is quoting junk science — his favorite kind of “science”. Leftists will lie about any subject to get what they want. They’ll include bird deaths from transmission lines as fossil fuel bird deaths as if solar farms and wind farms did not need transmission line. In fact they add even more transmission lines, often long lengths, since solar and wind farms are rarely located close to cities where lots of electrical power is used. Your problem, Barry, is a constant appeal to authority — quoting a study because you like the conclusion, with no thinking about whether the so called study makes sense, or is biased to reach a desired and/or leftist approved “politically correct” conclusion.
https://atomicinsights.com/nukes-kill-more-birds-than-wind/
Bingo call out the psychobabble!
When that stuff gets repeated either you are self-interested propagandist or a sucker for a self-interested propagandist.
That’s a good critique, Richard, and about the only thing of merit I’ve seen you bring to the table. I agree that it takes the Sovacvool studies apart, and that the evidence for nuclear killing more birds than wind farms is deeply flawed.

I have to agree with you on windmills. My observation is that wind energy is good as a supplement and alternative power source. Terrible idea to make it a Primary source with no viable means to store large amounts of power! If the US wants to develop wind it needs to do it in step with electrical storage systems or it is a really stupid pursuit. Wind, by its nature, is not reliable. It blows some days and then it does not. No thinking person would push it as a primary power source and eliminate reliable power without a viable storage system of electricity for when the wind does not blow.
The problem in Texas is NOT new. This article was written in 2019 and made the prediction: “However, without the proper financial incentives, more dispatchable fossil generation will exit the market, resulting in rising electric power prices, greater price volatility, and increased risk to the reliability of the electricity grid.”
https://www.americaspower.org/coal-retirements-have-ercot-power-prices-soaring/
The media is making claims that the windmills are not the problem with the Texas power outage.
https://www.texastribune.org/2021/02/16/texas-wind-turbines-frozen/
Texas wind capacity is 30,000 Megawatts.
https://en.wikipedia.org/wiki/Wind_power_in_Texas
http://www.ercot.com/content/cdr/html/real_time_system_conditions.html
http://www.ercot.com/content/cdr/html/CURRENT_DAYCOP_HSL.html
From ERCOT current energy production wind is only 3711 Megawatts, a little more than 10% of its capacity. More reliable energy sources such as Nuclear, coal would be able to achieve capacity production unless some problem prevented it (mechanical failure of some type). These are currently reliable power sources. Wind is not such a source.
Good post. Thats what I gather. Reading the various news reports the failure of the wind power was less than expected. They only expected 6% to be online. Whereas the natural gas power was less than expected.
In other words, the power managers are ahead of the game on the lack of reliability of wind power.
And of course keeping wells from freezing and storing natural gas is probably a lot cheaper than keeping the wind turbines turning and storing electrical power.
Lesson? One can make anything look reliable if expectations are really low or there is no limit on the amount of money you can spend.
“unless some problem prevented it (mechanical failure of some type). These are currently reliable power sources.”
Exactly what happened here. So not so reliable, unless a regulation requires it to be reliable in such circumstances.
And then when you factor in Texas’ inability to import electricity in times of supply/demand issues you have a recipe for disaster.
Hindsight is 20 20. Back up not necessarily needs to be import especially when that puts you under another regulatory scheme.
Could be a lot cheaper to simply provide some pump insulation but since natural gas pump freezing has been kind of the opposite of the political viewpoint no doubt its been neglected.
Kind of like when they were predicting in UK the end of snow events leading up to a record snow event and the stockpiles of road, bridge, and airport clearing equipment and supplies had been allowed to deplete.

The very first station I chose in Texas shows No warming, and in fact cooling, since 1900.

From 1897 to 2020 Burnet warmed 0.94C +/- 0.20 per the adj-homogenized dataset.
bdgwx: From 1897 to 2020 Burnet warmed 0.94C +/- 0.20 per the adj-homogenized dataset.
You simply can’t get more dishonest than that. Deliberately using “adjusted” data instead of the actual data.
Even using the adjusted data, the current temperature is basically the exact same value as that in 1897. How anyone would want to spin that into warming is beyond me, but no matter how you look at it, unbelievably dishonest and decietful.
CO2isLife
I am not sure how you can’t see a warming signal in the data you posted. Again if you take a piece of paper and line it on the 19 C mark you see much more significant peaks after 2000. And again if you go down to the 17 C line you see most years reach at least some points down to this level but none after 2000. I really do not understand how you process data. If you draw a line through the data it will rise upward.
I think your attack on bdgwx is not valid. I think if you put the unadjusted numbers in a spread sheet and draw a trend line through the unadjusted data you might find it shows a definite upward trend. Without running the numbers I can’t give you a value.
To be fair the unadjusted shows a negative trend. But it’s also pretty obvious that there are extreme discontinuities possibly caused by station changes that makes this trend meaningless. Obviously time-of-observation changes, instrumentation changes, etc. would be problematic as well.
That’s right. I “deliberately” used adj-homogenized because I want to know the temperature trend using a time series that has known errors and biases corrected. It would be unethical for me to provide you an estimate of the trend using data that has known errors and biases that have not been corrected. And by any rational thinker if would rise to fraud if I knew about it and didn’t tell you. I’m starting to wonder if you have a different worldview of right and wrong than I do and most everyone else.
What errors and biases are you aware of that were corrected bdgwx? And how was the correct answer determined of what the outside temperature really was 40 years after the alleged error was made?
Thats right. I deliberately used adj-homogenized because I want to know the temperature trend using a time series that has known errors and biases corrected.
That is absurd. They have actual data unadjusted from the time period it was taken. You honestly think you can take a data set in 2020 and go back and accurately adjust the data going back 140 years? That is absurd. They have no idea what the conditions were for those sites 140 years ago. What you do know is that almost every “adjustment” works to increase warming and make the trend more linear. That is a fraud. You have actual data and you have adjusted data, and you choose to use the “adjusted” data. That is absurd. Either way, even using the garbage adjusted data the current temperatures are still at the same level as 1897, or whenever the data started.
According to the metadata record Burnet USC00411250 had 8 relocations. In fact, it’s altitude jumped from 305m to 403m above sea level. That change alone creates a dramatic 0.6C drop in temperature if using the average 6.5C/km lapse rate. It’s TOB switched to 08:00 in 1945 and transitioned to MMTS in 1986. Are you guys suggesting that we should just pretend like none of that happened, perform climatic analysis on the unadjusted data anyway, and not disclose these issue to consumers of your results?

I don’t think anybody is saying data should never be adjusted.
Howver, sometimes its better to throw data out as opposed to manufacturing it as long as whatever you do you fully document and make transparent the reasoning and action.
elevation change is perhaps the most likely of valid adjustments but lapse rates are not all that consist. Some locations experience more inversion, have different humidities, and God forbid may already be adjusted. Temps on the ridge or building top can be a lot warmer than on the street below.
Auditors don’t audit back at their home office. Its a job done in the field looking at the data there and asking questions of those in charge. Doing 40 years later?. . . .well never done that.
The governor of Texas went on Fox news and tried to blame wind turbines for the problems of his state, while ignoring the much larger problem caused by Natural Gas and other power plants, and the lack of regulation of these.

Yep the experts know how bankrupt the global warming rhetoric is. Its just the petty bureaucrats are constantly under the pressure of spending money to guard against too much heat rather than too little.
How do you get that bizarre lesson from that?
The lessen is that under regulation can be as bad or worse than over regulation.
Sorry Nate but your political philosophy is as antiquated as physics. . . .perhaps moreso.
What overregulation and socialism have in common is a tendency to large disaster. Over regulation decreases diversity of business ideas and thus increases the chances of widespread disaster.
Under regulation may not substantially reduce disaster it just tends to reduce the scope of it when it does happen.
The greens enthusiastically embrace bio-diversity put for some odd reason flip-flop on diversity across the board. . . .why? Cause they are being conned by massive international NGOs and getting fleeced without them knowing it.
AGW is the same thing. Its about a massive government-sponsored transfer of wealth from oil interests to whoever does enough political favors and is willing to spend some of it on massive non-sustainable economic investments in unprofitable ventures.
Who gets burned? Well its hard to say the oil tycoons get burned. . . .often enough they are willing to line up at the hog’s trough and have enough wherewithall to prime the pump and even if they aren’t willing to do that they have plenty of assets taken in the form of dividends and other revenues to land squarely on their own two feet in very good shape.
Its everybody else that gets burnt.
“Under regulation may not substantially reduce disaster it just tends to reduce the scope of it when it does happen.”
Uhh, apparently the weeks events prove that FALSE. Did you not watch the news?
Good example of Conservative theory vs pragmatism.
The theory is that the Free Market can meet any challenge or need.
And the theory was applied to the extreme in Texas, with totally unregulated Electric Market. The Market failed to provide winterization of power plants and fuel pipelines.
Then when the lights went out and the $7000 electric bills driven by the Free Market arrived, politicians like the Governor Abbott and Ted Cruz were disavowing Market pricing.
Pragmatic conservative governing means having enough regulation to prevent such disasters.

===========================
Nate croaking away at stuff he knows nothing about as usual.
1) ERCOT the Texas grid that failed is not a) unregulated; b) not free market; c) ”the market” isn’t responsible for the grid.
The grid is regulated by the Texas Public Utility Commission and the Legislature. There is only one company. Parts of Texas along the fringes of the state opted out of the Texas ERCOT grid. the failure here is very similar to the California electric disaster a couple of decades ago that had a big role in getting the California Governor impeached.
Something like 3 other grids operate in Texas and were not part of this as they get their power from other regions.
ERCOT is only unique because its regulated by the State of Texas vs the federal regulation of the other grids.
Grids are natural monopolies so they really have nothing to do with free markets. Never have and never will. Try learning something Nate before flapping your jaws.
And you do understand it, because..?
“There is only one company.”
???
There are many suppliers. They were basically unregulated. Winterization was not required.
As you noted: “The grid is regulated by the Texas Public Utility Commission and the Legislature.”
Governor looking for scapegoats. ERCOT does not make regulations. They just manage the grid with the supply they have.
ERCOT “The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to more than 26 million Texas customers — representing about 90 percent of the state’s electric load. As the independent system operator for the region, ERCOT schedules power on an electric grid that connects more than 46,500 miles of transmission lines and 680+ generation units. It also performs financial settlement for the competitive wholesale bulk-power market and administers retail switching for 8 million premises in competitive choice areas.”

LOL!
Two facts need to always be considered. 1) power corrupts and absolute power corrupts absolutely. and 2) the bigger they are the harder they fall.
Regulation is a common substitute for the common sense above.
regulation inevitably leads to either corruption or collapse. Its why socialism doesn’t work at all.
In the power delivery business guaranteed contracts is the way to go. e.g. either the contracted party delivers on time or he pays for the most rapid alternative delivery and only receives his contracted rate. Consumers are protected against non-delivery and has recourse for damages for non-delivery.
Wall Street accomplishes the same approaches in the commodity markets.
But you take some government agency or not-for-profit and you have relinquished much of any chance of writing good contracts where bureaucrats are more interested in making points with the contractor, have no personal investment at risk with guaranteed employment and pensions and opportunities for fat consulting contracts to double dip into pension systems.
Regulation can have a role but regulation isn’t responsive, seldom is efficient, and is wholly unadaptable to changing conditions. So all too often regulation costs more to implement than the return for it given to the consumer.
As I pointed out this disaster is unprecedented and to some extent arises out of regulating alternatives and to the remaining extent is about the concentration of power. Its just too tempting to put all the eggs in one basket as a hog trough for insiders. It attempts to circumvent the 2 truths outlined above by concentrating power.
“Regulation can have a role but regulation isn’t responsive, seldom is efficient, and is wholly unadaptable to changing conditions. So all too often regulation costs more to implement than the return for it given to the consumer.”
My original point was this failure was “Good example of Conservative theory vs pragmatism.”
Your answer seems to be go with Conservative Theory anyway.
IOW do nothing, and let the Market take care of it. Which it didnt.
Nate you continue to miss the point.
The grid is what shut down. The grid evenly distributes what it gets. If demand exceeds supply the grid starts shutting down customers.
If you had multiple grids to choose from the ones that shutdown customers would lose business and people would shift to grids that didn’t shutdown. You want to blame the suppliers when all you need to do is ensure the blame bears the brunt of market forces.
So now that the quasi-government grid needs to respond to something they did not foresee. Asking the legislature to do it by regulation results in poor efficiency, unintended consequences, higher rates, less competition. If the grid does it by contracting supply or pay, businesses will want more money for their guarantees of supply but competition will force the price of those guarantees to the bare minimum. If the government wants to try to do that by regulation you will face corruption, bad ideas, zero innovation, and it will cost the consumers a lot more. In fact if the government does it select businesses will help them by trying to get conditions favorable to that particular business and they will succeed via the usual corruption of the political environment and consumers will pay.
bottom line Nate is for competition to work it needs both multiple vendors and multiple customers. A quasi-government agency or not-for-profit can sit as an intermediary in the situation of a natural monopoly like power distribution grids and it often works when really qualified people get put in charge whose future salaries depend upon good practices.
Rule 2 above states essentially that big grids may breakdown less frequently but when they do they tend to be bigger deals unless they have properly learned their lessons from their little brothers.
Nate you are wrong that FERC is regulated and ERCOT is not and that FERC. Thats just your ignorance speaking. They operate under essentially similar models to promote competition in energy supply. https://www.ferc.gov/industries-data/electric/power-sales-and-markets/electric-competition#:~:text=FERC%20issued%20a%20series%20of,888.&text=The%20President%20signed%20into%20law,open%20access%20to%20transmission%20facilities.
“Nate you continue to miss the point.
The grid is what shut down. The grid evenly distributes what it gets. If demand exceeds supply the grid starts shutting down customers.”
Indeed so. The Market for suppliers to the grid for suppliers to residences, as shown clearly in the ERCOT ‘ABOUT US’ description.
Thus problem was not ERCOTs fault.
The problem was that many suppliers simultaneously were shut down because of lack of winterization requirements.
Seems like you are missing this key point.
“If you had multiple grids to choose from the ones that shutdown customers would lose business and people would shift to grids that didnt shutdown.”
That is utterly absurd.
The grid is more analogous to the highway system. All the trucks drive on the same hi-way system, and the competition is between different trucking companies.
“Nate you are wrong that FERC is regulated”
??
I never said diddly squat about FERC.
You keep dodging the key element Nate.
The grid failed because of a lack of delivery.
You have looked at a newspaper and determined that the lack of delivery was a lack of winterization. . . .whatever that is.
The key issue was lack of delivery not lack of winterization. Delivery can, will and has failed for innumerable reasons. You don’t need regulation you need guaranteed delivery contracts such that the contractor that doesn’t deliver is liable for damages and must pay whatever rate is required to provide replacement delivery.
The problem is the facilitator has no cock in the fight. . . .trying to please everybody and make friends. I have worked as a consultant for a number of such intermediaries (other than electricity) over perhaps just the last few decades these intermediaries are developing skill sets to ensure open markets, competition, and responsibility.
Its not an easy road to hoe because suppliers want contracts without responsibility for obvious reasons. And what you don’t want is a bunch of bureaucrats and politicians specifying how they accomplish what they are supposed to accomplish.
All you need to do is make it such its the only route to profitability. . . .that’s the difference between smart contracts and regulation.
The biggest hurdle to over come is the politicians can easily get kickbacks out of regulation design. Identical contracts that adequately address responsibility provides no such opportunity, it simply becomes a choice of the consumer and supplier.
All you want is to contract for what the consumer wants delivered in the form of guaranteed delivery contracts.
Simply insisting on delivery is the conservative De Minimis approach that minimizes government’s role while maximizing innovation and the end result. then you wouldn’t be talking about consumers getting gouged on replacement power.
That is what I do go into some system that hasn’t been working well or has flat out failed as part of a consulting team, audit the situation, and make recommendations. Most of the time you find that the intermediary was trying to be too smart do too much when they should have left the details to those with the investment, motivation, experience, and expertise.
“You have looked at a newspaper and determined ..”
Indeed I have.
While you didnt bother to gather the relevant facts and just blurted out politically biased opinion.
Then, as so often, when called out on it, you have to walk much of it back. Why not get informed first?
Nate nothing got walked back.
The concept of ERCOT is to provide free market access to energy. ERCOT acts as the middleman regulating conditions. . . .powers granted to it by the legislature.
It seems obvious to me one thing you would want to have is some forms of protection against volatility and/or forms of consent to volatile rate shifts. Even Wall Street has that.
As to your lastest claim on the gov blaming wind energy. . . .indeed its justified.
The fact is some folks would rather burden natural gas with regulation rather than simply fixing issues of volatility and who pays for supply disruptions.
All you want to do is distract from inherent non-mitigatable risks of wind power and focus instead on mitigatable ignorance of not insulating well heads.
Wind power problems are the only political issue as nobody knows how to fix it. Subsidization is where you find it.
You guys want to subsidize wind power and wind power comes out the loser with smart volatility and supply protections. . . because wind power has higher costs associated with providing guaranteed delivery within a framework of smart volatility protections. Imagine the wind farm operators needing an insulated natural gas wellhead as backup.
So feel free to troll and dance your political jig all you want Nate. . . .and I will feel free to expose it for what it is.
Bill from the beginning you claimed it was not a market based system, had to walk that back.
You continue determined to miss the point,
“The problem was that many suppliers simultaneously were shut down because of lack of winterization requirements.”
And you keep trying to blame the GRID manager for this the lack of supply, and you already admitted that “The grid is regulated by the Texas Public Utility Commission and the Legislature.”, not ERCOT.
Texas was given a clear warning 10 y ago and failed to fix the problem.
Unclear what change you recommend to Texas to avoid this problem in the future?
Nate says:
Bill from the beginning you claimed it was not a market based system, had to walk that back.
==============================
I didn’t walk any of that back you just misinterpreted that I stated energy delivery via wire and pipe is a natural monopoly. A monopoly is not a free market system.
Texas’ ERCOT is designed to take what is not free market as a system and make certain elements of it free market through regulation and legislation. Name make just the fuel that travels on the lines and in the pipes free market.
To make that separation workable is a challenge as the centralized non-free market ERCOT grid has to establish the rules of the market (e.g. customers cannot drive down to the local gas station and fill up energy containers at the station of their choice, which if the price of gas just doubled they might forego a purchase and go home and allocate what fuel they have left as wisely as possible.
Choice before being charged is a fundamental aspect of true free markets. Who is going to get charged in now a topic of lawsuits.

———————–
Yes you are correct and the consumers had no opportunity to select on that basis so the attempt at creating a free market on that failed.
I said there are a number of ways besides regulating insulation of well heads and dreaming up some way of solving the massive shutdown of windpower which nobody has figured out yet and regulating that.
One way is to make power suppliers responsible to deliver at the “beat this price” level where the regulator doesn’t have to raise the instant price 700% to try to entice delivery.
A more detailed example would be like Wall Street volatility protections. Establish a price to beat allow it to change but put a limit on how much it can change in say a month.
That collars price volatility. Then the way to collar supply volatility is to demand that once contracted on a ”price to beat” basis the utility is bound to deliver a given number of Kwh based upon the number of customers that selected that particular supplier. Wall Street does it by selling options.
In this case the suppliers would determine their own risk and either buy coverage (say options for the delivery of alternative energy) protecting them from their own equipment shutting down
None of this is all that complicated. Its just a case that in new endeavors it usually takes a little time to get it right.
“I didnt walk any of that back you just misinterpreted that I stated energy delivery via wire and pipe is a natural monopoly. A monopoly is not a free market system.”
As shown, it is a Free Market for Suppliers, and a Free Market for Deliverers.
IDK why you keep ignoring these facts.
“Texas ERCOT is designed to take what is not free market as a system and make certain elements of it free market through regulation and legislation. ”
IDK why you think the Free Market arises from ‘regulation’?
Confusing.
This may be helpful to see what financial penalties were already in place but still failed to take care of the problem.
And you, and Right wing Media keep erroneously emphasizing Wind Turbines when the evidence shows that they were a minor, and easily fixed, part of the problem.

Nate says:
”IDK why you think the Free Market arises from ‘regulation’?
Confusing.”
It shouldn’t be confusing. Laws, regulations, and the Constitution is a framework of a broader category of regulation that this country operates from.
Thus the Bill of Rights is in the same category as regulation.
”This may be helpful to see what financial penalties were already in place but still failed to take care of the problem. And you, and Right wing Media keep erroneously emphasizing Wind Turbines when the evidence shows that they were a minor, and easily fixed, part of the problem.”
You must be confusing me with somebody else. I don’t think wind power should bear any additional responsibility.
The free market fix is to assign the same liability energy industry wide and let each supplier determine how they can mitigate that liability.
Each supplier should individually bear the costs associated of unreliability and be held to the same reliability standard.
Since wind power has been politically favored pushing management towards a failing micromanagement regime while knowing wind power has been less reliable. The right action and at the heart of my specialty is in ensuring costs get assigned properly and fairly.
It is very possible the Texas Governor is just doing CYA for somebody. But quite frequently you find with careful examination of public testimony that often administrations are aware of some risks, want to assign costs of reliability fairly, meet a lot of political opposition to that, and then everybody gets caught with their pants down. The bottom line is its well known how to go about regulating free market systems. . . .it just that there is a lot of special interest resistance against that from special interests and do gooders who really aren’t up to speed.
That is exactly what is inherent in micromanagement regulation and it does take a good deal of time and research to dig it out. Handing out hidden subsidies is a land office business in politics. And hidden is the key word nobody wants it known to be such. Assigning equal across the board liability for being responsible doesn’t provide an avenue for that corruption.
Great examples of that in everyday life is the ‘professionalization’ of a trade where performance standards, license, bonding, and insurance are the trademark of a profession, like doctors, engineers, accountants, contractors, etc. All that goes a long ways to ridding a trade of quacks.

==========================
Perfect you are commenting on an area where I have the most experience. The municipal utilities got nailed. Why?
Well in the ‘market’ that failed the municipal utilities are nothing but customers and consumers of energy. Worse they have contracts to sell energy to end customers at rates fixed by their own municipal regulators.
So here they are with huge prices for raw energy to power whatever they do like run generating stations and distribute electricity to end consumers and fixed rates coming from at least a portion of their customers as established by their local utilities commission. Kind of like California’s PGandE giant responsible for wild fires that killed something like 120 people.
Huge liabilities and fixed rate revenues.
The fix for this is in transferring the liability for failure to deliver to the suppliers. Its nice to think of for consumers to buy energy at the wellhead at a rate with practically no markup; but as we see from this event that isn’t 100% feasible. There needs to be like an insurance premium on top where the suppliers either insure themselves (like a contractor or other professional does) or places the risk in arbitrage where investors bid for the risk. It adds a small premium to the cost of energy but it is something most consumers would want for higher levels of reliability.
So suppliers might think they can mitigate the risk by insulating wellheads, for example, as opposed to putting the risk out to bid in an arbitrage market.
It might be attractive to think that risk can be mitigated by mandating wellhead insulation and be done with it. But risk is by far a more complicated beast than that and it leaves everybody else off the hook who don’t have wellhead freezing problems and shutdown anyway without fulfilling their role.
I am not an electricity expert but I suspect that what is needed is a brief time commitment on the part of suppliers. Since utility bills go monthly typically a month interval would have fixed this problem where rates are fixed in the short run. They already have opportunities for customers to get longer term rates up to 2 years. Having a range of time commitments would fit the bill probably pretty well for most but the answer to that is subject to a lot more information and is just a simplified example and not all inclusive of how to handle risk.
” dreaming up some way of solving the massive shutdown of windpower which nobody has figured out yet and regulating that.”
This wasnt you?
And more blurted nonsense.
There is no need to ‘dream up’ what ‘nobody has figured out yet’.
There are massive numbers of winterized wind turbines in states like the Dakotas with harsh winters.
Indeed Nate. Cold weather isn’t wind power’s Achilles heel. Biggest one is the wind not blowing.
They are hoping it will be blowing someplace else where they can borrow power in the north. Is that a good bet in this era of extreme weather? The wind not blowing would seem to be the most logical outcome of the weakening and slowing jet stream along with a lower temperature gradient across latitudes.
I am fine with wind power competing on a level playing field. Here at my house I don’t need imported monopoly power for heat. Its just a nice convenience to have when you want it. Some people like to be dependents though. It will definitely give them a lot to complain about like teenage children.

You wrote upthread:
” What should happen in a warming world is that local record-breaking highs should occur more frequently than local record-breaking lows in most if not all years recently. ”
Correct.
Recently, Roy Spencer published among other papers a short study made by Prof. Christy
” Are Record Temperatures Occurring More Often in the Conterminous United States? ”
*
within which he interpreted a parallel decrease of highs and lows reported by USHCN stations in CONUS since 1895, as a hint on extremes lessening there over time.
I wanted to see how the Globe would behave compared with CONUS.
Like I did 2 years ago, I took GHCN daily worldwide instead of the US-restricted HCN station set.
Like did Mr Christy, only stations with at least 105 years of activity were selected.
CONUS differs a bit from Mr Christy’s graph because
– GHCN daily has more HCN stations than the HCN set itself;
– I preferred to keep his original 2018 scaling (highs per station) instead of taking his newer one (highs per measurements).
Each chart shows in yellow the values without area weighting, and in red/blue/green those computed with area weighting (in addition to his blue lowest TMIN records, I generated data for highest daily TMIN values, in green).
1. CONUS TMAX
https://drive.google.com/file/d/1mdk43WKwvDYe3UTjUYyeF9MfktcacIKZ/view
The yellow stuff is similar to Mr Chrisy’s TMAX.
2. CONUS TMIN
https://drive.google.com/file/d/1LCMjreVGILlIy82tKbN9BQ2MM9kvdqs5/view
The yellow stuff is similar to Mr Christy’s TMIN.
3. Globe TMAX
https://drive.google.com/file/d/1qe7HVPQHnniK1F6CMUh5zoO6fL-314WE/view
Here we see that in opposition to CONUS, the Globe’s red stuff increases over the years when area weighting is activated, because one gets 170 US grid cells vs. 170 outside instead of 2107 US stations vs only 468 outside!
4. Globe low TMIN
https://drive.google.com/file/d/1q70BufrN6gKCHbt4guEO-Bg4JdephHhr/view
This is quite similar to the TMIN graph for CONUS. I don’t know why the TMAX graphs differ, but the TMIN’s nearly don’t.
5. Globe high TMIN
https://drive.google.com/file/d/1XCMCMGzaFqhcS46UggIAB4emjOpN4ELC/view
Here we see what is known since longer time: outside of CONUS, where it keeps nearly constant, the ratio of warmest, absolute night temperatures increases over time.
*
All in all, it seems to me that Mr Christy’s TMAX/TMIN study shows conclusions which are really only valid for CONUS, and cannot be transferred to the Globe’s land areas as a whole.
Yeah: CONUS, that’s 6% of Earth’s land surface.
J.-P. D.
The US is incredibly parochial.

Would then people like Grant Foster be as well?
I see the problem at a different level: John Christy is busy since years with writing testimonies destinated to the Senate’s most conservative lawmakers.
Such people aren’t interested in anything outside the US (some are even in nothing outside of CONUS).
One day you begin to slightly move from science into… politics.

I wrote those words at the end of a long comment that was worth reading. I typed them slow, so even YOU would understand it. Thank you for the complements, Bindoofus, but it was not necessary to call me a “genius”, and “superintelligent”. After all, how would YOU know?
A cat has instincts to kill birds for food. That’s why i have always kept my cats indoors. Do you hate cats too?
Windmills are build by choice. Through the use of large government subsidies, tax credits and mandates to use them (or solar panels).
Otherwise the wind industry would practically disappear.
After they are built, windmills take up a lot of space, provide intermittent, highly variable, unpredictable energy, kill birds and bats, cause health problems with their infrasonic noise:
https://elonionbloggle.blogspot.com/2020/10/wind-power-infrasound-noise-problem.html
… and windmills are ugly too.
Windmills are substandard electricity generators for the modern world, unless battery prices decline by about 90%.
The windmills kill lots of insects, which attracts smaller birds for meals, and then some of them are killed, which attracts larger birds for meals, and then some of them are killed, which attracts animals for meals.
There is no way to accurately count dead birds and bats near windmills (not all of them die right next to the windmills) because they become part of nature’s food chain.

Too bad you can’t think about these issues by yourself, and always resort to the appeal to authority logical fallacy — “I read a report on birds that I like, by an “expert”, so it must be right”.

” Too bad you can’t think about these issues by yourself, and always resort to the appeal to authority logical fallacy… ”
Typical pseudoskeptic nonsense.
Each time people like you, Robertson, Swenson or the like go out of arguments, you all automatically invoke “appeal to authority”.
That, Greene, is simply stubborn.
Btw: no, I don’t hate cats.
Start thinking, Greene, instead of writing such trrivial stuff.
Maybe thinking brings you near to the fact that cats are no longer wild animals, but are animals that are completely overfed by humans and that kill birds not out of need, but out of instinct and lust.
Oh Noes! Is that soo difficult, Greene?

If it criticizes fossil fuels, it must be wrong.

Well besides lust being a very poor description of a cat’s native instincts or have a concept of being overfed. Cats live in packs and families.

10s of people have died, and the cold spell isn’t over. The cost of electricity is/was $9,000 megawatt, and it cost $900 to charge your Tesla. Only a complete and utter fool would continue to argue for “diversifying” energy supply by adding unreliable energy sources to the portfolio. No “science” would even support such foolishness. Trust the Environmentalists at your own peril. They offer no solutions, only anti-capitalism rhetoric. China is building coal and nuclear plants, they build wind farms only because they get paid to do so, and many aren’t hooked to the grid. China doesn’t have a “Green Movement.” Environmentalists who put the environment above the state join the Uygurs in their concentration camps supplying labor to “dirty” power plant construction projects.

“In 2019, Texas had a total summer capacity of 125,117 MW through all of its power plants, and a net generation of 483,201 GWh. The corresponding electrical energy generation mix was 53.5% natural gas, 19.0% coal, 17.3% wind, 8.6% nuclear, 0.9% solar, 0.3% hydroelectric, 0.3% biomass, and 0.1% other sources.

Yeah. And now… read this below!!!
From ‘The Texas Tribune’
https://www.texastribune.org/2021/02/16/natural-gas-power-storm/
Texas largely relies on natural gas for power. It wasn’t ready for the extreme cold.
” Failures across Texas’ natural gas operations and supply chains due to extreme temperatures are the most significant cause of the power crisis that has left millions of Texans without heat and electricity during the winter storm sweeping the U.S.
From frozen natural gas wells to frozen wind turbines, all sources of power generation have faced difficulties during the winter storm. But Texans largely rely on natural gas for power and heat generation, especially during peak usage, experts said.
Officials for the Electric Reliability Council of Texas, which manages most of Texas’ grid, said the primary cause of the outages Tuesday appeared to be the state’s natural gas providers. Many are not designed to withstand such low temperatures on equipment or during production.
So, when you read CO2isLife’s incredible attacks, you know that this commenter is either an Ignoramus, or a… liar.
J.-P. D.
There are 3 electric grids in the United States. The western interconnect. The eastern interconnect. And Texas. Yep…Texas operates their own independent and isolated electric grid. They do not have the ability to import electricity from other regions like every other state does. That was by design. The breakdown of self sufficiency and the inability to receive a lifeline from outside is a huge contributing factor to the problem as well.
bdgwx
That makes all those ‘expert’s here looking full dumb, who ranted against renewables, or more especially windmills, for having been the major cause for Texas’ energy disaster.
*
Headline on the website of the German newspaper “Der Tagesspiegel”:
” Millionen Amerikaner ohne Strom und Wasser: Gouverneuer von Texas sieht Schuld in erneuerbaren Energien
But in the article text you read, translated in English
In fact, wind power only accounts for about 7 percent of the state’s total capacity at this time of year. According to experts, a large part of the power outage is due to frozen pipelines.
Greg Abbott finally admitted in a press conference on Wednesday afternoon that frozen wind turbines are not the main cause of the electricity shortage.
J.-P. D.
badwax sez: “That makes all those experts here looking full dumb”. I guess you would be an expert on the subject of dumb.
Here are some facts from my Texas wind power article a few days ago, where you can look at charts of wind power by hour on several days. Averages tell you little. There are huge variations from day to day, and even during a day:
“Just a week before the outages of Monday night, wind output was strong throughout the day .. in terms of its capacity factor (64%) and percentage of the ERCOT load (58%):
But wind production looked entirely different on Monday night and Tuesday morning: … during the critical four-hour period from 10 p.m. to 2 a.m. when ERCOT was forced to begin rolling blackouts, actual wind output averaged less than 5% of the ERCOT load.”
The whole article and many charts are here:
https://elonionbloggle.blogspot.com/2021/02/wind-subsidies-help-freeze-texans.html
bdgwx: According to the metadata record Burnet USC00411250 had 8 relocations. In fact, its altitude jumped from 305m to 403m above sea level. That change alone creates a dramatic 0.6C drop in temperature if using the average 6.5C/km lapse rate. Its TOB switched to 08:00 in 1945 and transitioned to MMTS in 1986. Are you guys suggesting that we should just pretend like none of that happened, perform climatic analysis on the unadjusted data anyway, and not disclose these issue to consumers of your results?
OK, let’s look at the adjustments then. From your description, there would have been a 0.6 Degree Immediate drop in temperatures with the change in the raw data. There is a giant step at 1945, so that adjustment looks appropriate. Using the “Adjusted” Data, and starting the regression in about 1935 when it peaks, you still get a negative trend through the current. 85 years of no warming. Still want to argue warming is a problem for Texas? 99% of the “adjusted” data is below 1935. Almost all warming had occurred by 1935. Current temperatures are at the level of 1897. Temps in 2005 were near an all time low. Basically, there is 0.00 evidence CO2 is causing warming in Texas.
Same story for these other Texas Stations.

bdgwx, run your regression from the 1930s peak and you will get 85 years of no warming. Funny how your regressions only show warming if you include the early period of warming, and then ignore the cooling during the period when CO2 increased the most.
Dr. Spencer, bdgwx has identified a great project for a Ph.D Student. What are the slopes of regressions that start at the 1930s or earlier peak? You will see the CO2 causes no warming during the period of major CO2 increase.
CO2
To look for climate change, one must look at trends in the average temperature of large regions, whole continents. Only then is the local variation caused by weather, reduced enough to see the underlying trend.
But you keep wanting us to look at individual towns to see trends, but that is quite pointless. They all have huge local variation due to WEATHER.
It seems you prefer data that has so much noise that any trends are swamped by that..
I have to admit Nate is right.
Climate is a long term average of weather.
The measurements have not been very accurate until the 1970s.
Very inaccurate in the 1800s and earlier.
A single global average is a rough estimate, especially before the 19oos. Since 1979, satellites give us an opportunity for more accuracy in seeing where the warming was strongest and weakest. That’s more important than a single average, because not one person lives in a global average temperature.
I have no idea why individual weather stations are considered to be important, EXCEPT for an analysis: A history of changes to the location, the current siting versus optimum siting, along with economic growth in the vicinity and instrument changes over a long period of time. A history study of an individual weather station would tell us how many variables have changed OTHER THAN the temperature.
We can put objective definitions on your word choices.

You can’t guess temperatures for half the world and then claim you know a margin of error for the global average that you calculated. The global average is not a temperature measurement, it is a statistic. It is a statistic that consists of very little data (actual measurements) because of so many adjustments to the raw data. Any adjustment to raw data changes the number into an opinion — no longer real data. It becomes an opinion of what the data would have been if measured correctly in the first place. Every adjustment has the potential for error just like the original measurement did.
The global coverage was haphazard in the 1800s. The thermometers used in buckets mainly in Northern hemisphere shipping lanes, and manually read, would be +/- 0.5 degree C. at best. So there is no way the global average margin of error could be less than +/- 0.5 degree C. … BUT it would actually have to be larger than that because so much of the planet is infilled with guesses that can never be verified.
Your problem continues to be far too much trust of people in authority, badwax — government employees making ridiculous claims of accuracy for their 19th century and early 20th century numbers. You trust too much, and think too little. All appeal to authority, and no common sense.
RG said: Baloney
Then present evidence to back this up. Evidence would be an alternative dataset that computes a global mean surface temperature with an uncertainty analysis that is significantly different then what all of the other datasets publish.

There is absolutely ZERO appeal to authority here. I never said the uncertainty is what it is because of who made the claim. I said it is what is because of the evidence I linked to. And I didn’t even scratch the surface of all the evidence available. The evidence is massive and convincing.

Hmmm, you spend a lot of time talking about ”accuracy” and other such nonsense like ”standard error” surrounding GISS temperature records when none of that does anything to address real concerns like UHI, undocumented adjustments, or even the record itself which is not a random statistical sample.
What exactly is that you think is proven by ”standard error” and how is that relevant to the well expressed concerns surrounding the records?
Absolutely. Dr. Spencer presents evidence of the UHI effect.
You presented an evidence backed argument with your criticism of BEST’s use of MOD500 instead of GRUMP.
This is the type of thing that I appeal to.
Now we need to get Dr. Spencer to compute a global mean surface temperature with a rigorous uncertainty analysis, publish it so that everyone can replicate and review it, and then we’ll compare it to all of the other datasets that are out there and draw conclusions from there.

The peak actually occurred in 1938 so I’ll start from there. I assume you don’t mind. So from 1938 to 2020 the change in temperature at Burnet USC00411250 from the adj-homogenized dataset is +0.88C +/- 0.22. The trend is +0.11C/decade +/- 0.03.
bdgwx: Sigh…not even close. You’re eyes are deceiving you again.
Really? How can you possibly claim your regression is worth anything when the current values are BELOW the level in 1938. The level in 2005 (eyeballed) is near a record low. The level in 1978 (eyeballed) is a record low if 1938 is a peak.
My eyes aren’t deceiving me at all, you are distorting the validity of a garbage regression. Just look at the standard deviation. No way in the world is the current value 2 or 3 standard deviations from any mean you choose.
Dr. Spencer should have a grad student take all the charts that I’ve posted and there are many many many more and have that student pick a pre-1940 peak and run regressions through the current to demonstrate that almost all stations will show no warming if only a min effort is applied to control for the UHI and WV. Texas is a desert, most of their stations will show no warming.
CO2isLife said: Just look at the standard deviation. No way in the world is the current value 2 or 3 standard deviations from any mean you choose.
That has nothing to do with the warming trend though. That is a measure of how much variability there is in the data. And there is a lot.
The SD on the data is 0.69. That means we expect 68% of the samples to be within 0.69C of the mean. That tells you nothing about how the samples are evolving with time though.
To see how the samples evolve with time we do a linear regression of the y-values (temperature) and x-values (years – 1 based). That gives us the slope of the line that tells you how temperatures are evolving with time. The slope is +0.0076C/yr +/- 0.0016.
And now we have the trendline we can analyze the yearly deviation from the trendline. The standard deviation of the difference between the actual value and the trendline is 0.63C. What that means is that is we expect 68% of the yearly temperature values to stay within 0.63C of the trendline. But the trendline is moving up. What that means is that the 16.29C record low in 1903 comes with z-score relative to the trendline of -2.19. But the equivalent z-score in 2020 would be -3.60. These are probabilities of 2% and 0.01%. In other words whatever is driving that upward trend in the temperatures made the record low of 16.29C 200x less likely in 2020 than in 1903.
In a nutshell…you have conflated the variability of the data with the evolution of the data wrt to time. We aren’t trying to answer questions concerning how noisy the data is right now. We are trying to answer questions concerning how the data evolves with time. Big difference.
CO2isLife,
I want to provide instructions so that you can do linear regression trends yourself.
1. From the GISTEMP station map page make sure adj-homogenized is selected. https://data.giss.nasa.gov/gistemp/station_data_v4_globe/
2. Search for the station.
3. Click the csv link underneath the graph.
4. In Excel fix the 999.9 records in column R. Use whatever technique you feel is appropriate. I use linear interpolation as a quick and easy fix. There are other strategies that can be used. In the end it won’t really affect the result that much regardless of how you do it. But you do need to fix the 999.9 values somehow because they are so high that they will definitely skew the result.
5. Select a 3×3 array of empty cells. Enter =LINEST(Rx:Ry,,true,true) and press CTRL-SHIFT-ENTER to enter the array formula into those cells. Rx is the starting point of the regression where x is the row number and Ry is the ending point where y is also the row number.
6. In the array returned by LINEST R1C1 is the slope. R2C1 is the standard error of the slope. R3C1 is the R^2. To get the trend in C/decade multiple R1C1 by 10. To get warming over that period multiple R1C1 by the number of years. Remember to multiple R2C1 by the same amount to normalize the standard error to the length of period you are analyzing.
bdgwx
I’m not quite sure of him still being unaware of LINEST().
What he imho might be trying is to perform a multiple regression covering temperatures and CO2, using something like

Lampasas (31.0717N, 98.1847W) ID:USC00415018
https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=USC00415018&ds=14&dt=1
Dr. Spencer you should have a grad student identify all these stations that show no warming.
From 1889 to 2012 the station warmed 0.61C +/- 0.21. There is a pretty high uncertainty on that one, but it still shows statistically significant warming of at least 0.19C at 95% confidence. The warming could be as high 1.03C though. Ya know…you can just follow the instruction I posted above and do these yourself.
bdgwx, are you honestly trying to argue that you consider Lampasas is showing an uptrend that can be attributed to CO2? There is no uptrend what so ever if you define the uptrend as a series of higher highs and higher lows that would occur with a continual increase in W/M^2 due to CO2.
Here are the facts regarding Lampasas
1) current temperatures are below almost all measurements between 1880 and 1940 (Eye Balled)
2) I just ran the regression and get a (-) coefficient until 1920(Start 1891)
3) the slope in 2012 using the annual date is 0.007 degrees per year, basically zero.
4) Start the regression in 1922, you get a negative coefficient up to 1997.
Facts are the data is so volatile, volatility that can’t be attributed to CO2, that you can pick a data point 1 or 2 years apart and completely reverse the coefficient. Facts are every one of the charts I posted have multiple decades of flat to falling temperatures. Observations that simply are inconsistent with CO2 driven warming.
ALso, with that kind of volatility none of your regressions have any certainty at all. None of those data sets have an r-square over 90, so as I said and demonstrated that I can pick time periods with significant coefficients with the exact opposite sign depending on the time period chosen. If that is the case, the coeficiends are garbage.
“None of those data sets have an r-square over 90”
?? Do you know what you are doing ??
r squared values are less than 1 by definition.
Are you equating r square values with confidence levels?
They have nothing to do with confidence levels until you know the number of degrees of freedom in the data.
Maybe go back to school on this.
CO2isLife said: are you honestly trying to argue that you consider Lampasas is showing an uptrend that can be attributed to CO2?
I’m saying there is uptrend. It is statistically significant. The question of attribution is a different matter and cannot be assessed with this data alone.
CO2isLife said: There is no uptrend what so ever if you define the uptrend as a series of higher highs and higher lows that would occur with a continual increase in W/M^2 due to CO2.
Nobody declares a trend either way based on cherry-picked samples. And no, higher highs and higher lows is at all sites is NOT an expectation of global warming regardless of which agents are contributing to the global warming.
CO2isLife said: Facts are the data is so volatile, volatility that can’t be attributed to CO2, that you can pick a data point 1 or 2 years apart and completely reverse the coefficient.
Yep. I totally agree. In fact, that’s what I’ve been trying to tell you. Can we drop this strawman argument now?
CO2isLife said: Facts are every one of the charts I posted have multiple decades of flat to falling temperatures.
Yep. And that is totally expected.
CO2isLife said: Observations that simply are inconsistent with CO2 driven warming.
Not all. Not only are these observations consistent with CO2 influenced warming, but these observations are expected given our current understanding of ALL radiative forcing agents including but not limited to CO2.
CO2isLife said: ALso, with that kind of volatility none of your regressions have any certainty at all.
I provide the standard error on ALL trends I’ve posted.
CO2isLife said: None of those data sets have an r-square over 90
And as I’ve explained that is not unexpected given the high variability of the data. But remember variability should not be conflated with the trend so stop doing it.

bdgwx :

Could you explain a little more what this means? : Are the coefficients related to the steepness of the trend?
No. The R^2 is not a measure of the error of the slope of the trend. It is a measure of how closely the individual monthly means cluster near the trend. R^2 = 1 would be a perfectly straight line. But since weather still happens we expect a lot of variation or noise on the temperature measurements and thus a low R^2. That does not mean that the trend can have a positive slope with a low error.

???? R-Sqr is the explanatory power of your regression. A 0.00 means your regression has 0.00 explanatory power, and any associated values the Alpha and Beta are also meaningless. That is what I’ve been trying to tell you. R-Square = Regression Sum of Square Error/Total Sum of Square Error, the closer the Regression SSE is to the Total SSE the more explanatory power you have.
In your regression you are making an assumption that CO2 and Time are linearly related, because the real regression you want to run isn’t Temp = Y-Axis and Time = X-Axis. Many things, like the orbit of the earth, irradiation and other can change over 140 years along with CO2.
If you were serious about your regression analysis you would run Temperature = Function of ΔW/M^2 which is basically Temp = Function of log(CO2). It is not a linear trend, so if you had any idea about the physics of the CO2 molecule, you would understand that a linear trend, which is exactly what LINEST is, proves CO2 ISN’T the cause of the warming because CO2 isn’t lineraly related to ΔW/M^2. That is what no one in the entire field of Climate “Science” doesn’t seem to understand. Temp isn’t linearly related to CO2, temp is liearly related to W/M^2, and CO2 isn’t linearly related to W/M^2.
If you understand those concepts that are 100% undeniable you will understand just how wrong you are. You are literally arguing against quantum physics.
“that a linear trend, which is exactly what LINEST is, proves CO2 ISNT the cause of the warming because CO2 isnt lineraly related to ΔW/M^2.”
Why do you insist on posting such dumb things, CO2?
CO2 growth has been ~ exponential over last 50 y or more.
As you should know log(exponential growth) gives linear growth.
The temp rise has been ~ linear over last 50 y.
Nate: Why do you insist on posting such dumb things, CO2?
What you are saying is that just by chance the log growth in CO2 caused by man exactly offsets the log decline in W/M^2. Let’s test that:
Pre-Industrial CO2 270 PPM = 330.404 W/M^2
Current CO2 415 PPM = 298.363 W/M^2 Δ2.04
CO2 increasing from 0.00 to 270 added 29.3 W/M^2
I want you to do an experiment in Excel. Put a series of values 1-1000 in column B. In column B put the formula =rand() * 1000 and copy it down. In column C put the formula =A1+B1 and copy it down. A is the signal, B is the noise, and C is the signal+noise.
Then in a 3×3 section enter =LINEST(C1:C1000,,true,true). The signal produces a slope of 1 on the data, but the noise makes the variability of the data high. As a result you will notice that the slope is close to 1, but not exactly. The standard error will be around 0.03. And because there is so much noise the R^2 will be around 0.5. Play around with the noise level by multiplying rand() by smaller or higher amounts. Play around with the number of samples by extending the number of rows in your spreadsheet.
What you will observe is that as noise goes up the error on the trend goes up and the R^2 goes down. And has noise goes down the error on the trend goes down and R^2 goes up. Also notice that even with low values of R^2 there is high confidence in the trend slope. Even with R^2 of 0.2 I see 0.1 error on the trend slope of 1.0. In other words, even with R^2 of 0.2 we can eliminate slopes < 0.8 with 95% confidence.
CO2isLife said: If you were serious about your regression analysis you would run Temperature = Function of ΔW/M^2 which is basically Temp = Function of log(CO2).
Why would I bother doing so on an individual station basis?
Why would I bother doing so by only including CO2’s RF?
I already know what the result is going to be. There is going to be very little correlation.
What would give us higher correlations is doing all of this on the global mean temperature and for the net of all radiative forcing agents.
CO2isLife said: so if you had any idea about the physics of the CO2 molecule, you would understand that a linear trend, which is exactly what LINEST is, proves CO2 ISNT the cause of the warming because CO2 isnt lineraly related to ΔW/M^2.
Absolutely not. These linear regression trends on individual stations say nothing either way as to what is the cause of that trend. Nevermind that it says nothing at all regarding the trend of the global mean temperature or its causes either. Attribution of causes is a completely different topic that can only be assessed with vastly more data.
Your number 1 mistake here is your unbridled and irrational insistence that CO2 and only CO2 is the sole driver of all temperatures changes regardless of the spatial and temporal scales being analyzed. I have to be honest…this insistence by you and you alone is beyond baffling. I literally know of no one else that even remotely thinks this hypothesis has merit.
b,
Radiative forcing agents?
Say again? More obscurity – no doubt you will trot out bizarre jargon about energy imbalances, and other similar rubbish.
Learn some physics.
By the way, you might like to learn the definition of hypothesis.
What phenomenon are you trying to explain?
bdgwx: Your number 1 mistake here is your unbridled and irrational insistence that CO2 and only CO2 is the sole driver of all temperatures changes regardless of the spatial and temporal scales being analyzed.
If CO2 isn’t the cause, why does anyone care? None of this nonsense existed when climate change was considered natural…which it is. Climate Science wasn’t even a major when I went to college. If you want to get research funding you basically have to tie the conclusion to CO2 being the cause. That isn’t by accident. The only reason this nonsense exists is because the Tobacco money has run out the the socialists need another host. What is the greatest host of all time? Energy. Something people can’t do without and have to buy regardless of the tax. That is what this is all about and that is why they tax carbon, have carbon offests, try to sequester CO2, stamp out the Coal and gas industry. If CO2 isn’t being blamed as the cause, why did we just put 12,000 pipeline workers out of work, and why in the world would Texas build wind and solar farms when oil and coal are so cheap?
If CO2 isn’t the cause, why are we focusing everything in replacing fossil fuels?
CO2isLife,
CO2 and other GHGs are a cause of the planetary energy imbalance and cumulative energy uptake over the last 140 years and especially the last 60. And they happen to be a significant contributor accounting for well over 100% of the uptake. Note that it is over 100% because aerosols provide a negative radiative force that partially offsets the RF of GHGs.
This is a planetary scale phenomenon that can only be assessed by measuring the global scale heat uptake in the land, cryosphere, hydrosphere, and atmosphere. The excess energy/heat gets distributed throughout the entire system with various heat transfer processes constantly moving the energy/heat around. You simply cannot assess the global scale changes in the climate system by myopically focusing on small spatial and temporal elements of the system. The entire troposphere (not just the surface) stores only 1% of the excess heat. The cryosphere takes up 4%, land 6%, and ocean 89%.
Read though this publication.
https://essd.copernicus.org/articles/12/2013/2020/essd-12-2013-2020.pdf
Ask questions if there is something you do not understand.
If you regard a linear regression method like Pearson’s r as inadequate, why not use Spearman’s rank correalation p?
This isn’t rocket science. People claim CO2 traps heat. If a temperature in the last decade is below that of 100 years ago, there is no way CO2 trapped any heat in the atmosphere. You don’t need a regression to know that. The atmosphere isn’t a battery. It doesn’t store heat over time. If it cooled to 10 degrees, and then warmed to 20 degrees, extra energy had to be added, and CO2 doesn’t add extra energy. All it can do is slow heating by milliseconds. Radiation rapidly moves energy out of the system. In fact the CO2 signature can’t even be identified until you are up about 3km when water vapor starts to precipitate out.
CO2, you have the wrong analogy. GHGs don’t “trap heat” the way a battery “traps electrical energy” and can store it for later. GHGs “trap heat” the way extra insulation on your house “traps heat” during the winter. The way that closing a window “traps heat”.
C,
Entropic Man is not terribly bright. He refuses to acknowledge that all the heat of the day escapes to outer space at night.
He refuses to believe that the seasons exist, and all the heat of the summer is nowhere to be found in winter.
For all I know, he thinks the Earth has not cooled since it was a complete molten mass.
He might be silly enough to believe that Gavin Schmidt is a climate scientist, or that Michael Mann is a Nobel laureate!
Oh well, the rich fantasy world of the CO2 alarmist!
Tim, greenhouse gases don’t trap heat like a window because windows don’t rapidly diffuse or convect.
Analogies aren’t science yet science rides on an analogy for AGW.
If greenhouse gases worked like a window then greenhouse experiments would not fail using IR transparent comparisons to IR Opaque.
so we are at the crossroads of one lie crossing another. Greenhouse gases both don’t and do work like greenhouses.
Bill says: “Analogies aren’t science… “
I absolutely agree. Analogies are simply way to make ideas intuitive to beginners.
“greenhouse gases don’t trap heat like a window because windows don’t rapidly diffuse or convect.”
You misinterpret the analogy I was making. (And CO2 misinterprets the analogy in a *different* way.) Since no analogy is prefect, it is often important to explain the analogy, or different people will take away different conclusions than were intended. The analogy is only SORT OF like closing a window.
A house in winter (with a furnace always running) can lose energy via many paths (like thru the walls or through the roof or through cracks around a door or through open windows). Like the earth’s surface can lose energy via many paths (like convection or evaporation or radiation to space. That is the analogy.
Limiting one specific path of heat loss like closing one window reduces the heat loss for a house and will make the house warmer (again, with a furnace running). Similar limiting one specific path for heat loss like some specific wavelengths of radiation leaving to space will reduce heat lose for the earth and lead to warmer temperatures.
The analogy here is that of limiting a path for heat loss. The analogy is not specifically stopping convection or conduction like a window. Just limiting *some* form of heat transfer (some wavelengths of IR radiation).
“… yet science rides on an analogy for AGW.”
No. The analogies come FROM the theory, as a way to make the ideas intuitive to non-experts. The analogy do not create the theories. Scientists do not look to “greenhouses” or “blankets” or “traps” as the basis for the theories.
Well here is the bottom line on Lampasas, TX. 1) its primarily rural. 2) population has fluctuated over time both lower and higher than present in the distant past. 3) two temperature records a) observations; b) desktop observation adjustment record. Since absolutely zero documentation appears to be available on the sites reference a seasoned investigator would give equal weight to both records.
Results indicate a slight cooling trend without further informative input.
All that statistics mumbo jumbo means nothing. There is nothing here that can’t be easily seen with an eye.
bill hunter, from your comments, they can be applied to every station, so what you are saying is that none of this data can be trusted. I don’t agree, the more you look into this garbage, garbage used by NASA to perpetrate a fraud, the more a joke the conclusions reached using this data become. NASA just landed a rover on Mars. I assure you, none of those real scientists would support what the NASA CLimate Scientists are doing. NASA GISS is an embarrassment to NASA, and your comments prove that.
Can you provide another dataset that feel is not garbage that publishes a global mean surface temperature with uncertainty analysis that you want us to review?
b,
Why would anybody think that the opinions of you and your ilk are anything other than a cause for laughter?
How about reviewing * Atmospheric CO2: Principal Control Knob Governing Earth’s Temperature *?
One of the more ludicrous claims is * Without the radiative forcing supplied by CO2 and the other noncondensing greenhouse gases, the terrestrial greenhouse would collapse, plunging the global climate into an icebound Earth state. *!
Review away. Give all the rational commenters a good laugh.

Thermometers measure degrees of hotness, not concentrations of CO2.
Temperatures are measured in degrees, not W/m2, but the usual run of alarmist idiots live in denial.
bdgwx: Can you provide another dataset that feel is not garbage that publishes a global mean surface temperature with uncertainty analysis that you want us to review?
I’ve done that nteenth million times. That is why I keep posting links to cold and dry desert locations. Identify locations that are shielded from the UHI and Water Vapor and you get a natural control for isolating the impact of CO2 on Temperatures.
This is my favorite:

From 1889 to 2012 Lampasas USC00415018 warmed 0.65C +/- 0.21. The station is on its 7th relocation. The TOB switched to 07:00 in 1946 and then to 06:30 in 2000. It switched from an unknown instrument type to MMTS in 1986.
So how do you know any of those changes had an effect on the temperature readings?
GHCN use the pairwise homogenization algorithm. The publications regarding GHCN and PHA are too numerous to post here so I’ll just post the overarching GHCNv4 publication. I recommend reading this and then taking a deeper dive into PHA itself.
https://journals.ametsoc.org/view/journals/clim/31/24/jcli-d-18-0094.1.xml
We know these changes had a significant impact especially between 1945 and 2000 because the adj-homogenized data differs significantly from unadjusted. PHA is what runs to identify, quantify, and correct inconsistencies in station records.
You mean assumed inconsistencies bdgwx. You obviously have no experience in either intelligently filling out a government form or give consideration to what a station manager might do to provide the most correct answer on the form.
I’m not sure I understand your point. No one is assuming anything about the existence or nonexistence of inconsistencies. That’s why PHA applied. It’s job is to identify and correct inconsistencies if they exist. If they don’t then that’s great.
LOL!
bdgwx I already asked you why you thought all these adjustments are merited. Near as I can tell initial adjustments was a process of weeding down stations to a much smaller number tossing out any hot station on the basis of finding some inconsistency somewhere in the data. (more on some inconsistency later)
Now after the adjustment a great deal of skeptic scorn was thrown in the direction of the effort for few stations dominated by UHI. Indeed I heard all of California had something like 5 to 8 stations left (though I didn’t verify).
Now this new round of homogenizing adjustments is adding stations back in after, not surprisingly they have been corrected and compiled in a way to mostly not affect the existing trend.
Homogenization presumably is where you might use the remaining UHI affected stations to correct via interpolation with the tossed out stations so now they can claim a lot of stations.
So what you have is a lot of guys completely in denial of UHI making adjustments to temperature records accordingly.
Roy’s post here highlights that issue. So as a professional auditor what do I have to say. Well one is you need to learn to walk before you run. We have seen and you are aware of Berkeley Earth falling on its face on obviously ignorantly selected to support the case for zero UHI. I mean you really need to identify where UHI might exist. It has long been recognized as a temperature affect associated with population. I have never seen it characterized as existing as a trend in a heavily populated area with a steady population. There it has always been characterized as simply being warmer but not trending faster. (up to 2C warmer).
So Berkeley Earth comes along an picks areas for examination without population trends and instead just selects the most densely populated areas (which Roy’s analysis in figure 1 suggests doesn’t have population trends).
Now since the whole process of homogenization, station adjustment, station weeding, correction, and reintroduction has all been done with experts that no nothing about UHI; it seems to be crying for a whole new start in developing a surface station record from the raw data. . . .but of course only after you get those people to come to a recognition that the UHI matter needs to be addressed in a satisfactory manner first.
So my comments are in regards to spinning our wheels on adjusting station records to quickly assemble a temperature record to do something that the samples being nonrepresentative and never designed to do.
Understand bdgwx I am not favoring an outcome. I am leaning towards a lower trend for the surface records due to ignorance and I can accept the possibility that the original RSS and UAH records possibly could have understated it. But what I do know from my own experience in dealing with science issues at policy levels is that you frequently really do see a lot of real consensus and you don’t have to depend upon a phony consensus sold as propaganda to a gullible population.
So the bottom line is I have to laugh at this homogenization stuff. Ignorance has a tendency to march on like lemmings over a cliff.

As usual Bindidon you are so disconnected from all this you can’t even point out which assertion you disagree with, much less why.
” There is nothing here that cant be easily seen with an eye. ”
It should not be so difficult to keep as near to the data as possible, bdgwx has shown how to do:
https://tinyurl.com/22gxnx9e
no he doesn’t know how to do it Bindidon.
bdgwx has shown a ability to take one cherry picked viewpoint and crank out some statistics from it an offer it up as an answer. . . .and all he has done is become a mouth piece for the guy that picked what they wanted him to look at.
A better way is with the eye after you have clicked on the non-highlighted unadjusted numbers, which conveniently still show up lighter than what they want you to look at but at least its good enough to see a much better picture of a range of uncertainty. When you do that its an obvious cooling trend and all bdgwx could come up with is some mumbo jumbo about a warming trend.
Now I am certainly open to more information if anybody wants to provide any but I suspect the answer there is like Phil Jones said in his email to fellow conspirators that he would rather destroy the raw data than give it to the likes of Steve McIntyre because he was sure Steve would find something wrong with it.
I’ll remind you that I’m not the one selecting these sites.
No. Trying to eyeball a trend from noisy data is not going to be better than the purely mathematical and repeatable approach of linear regression.
No. Using unadjusted data is unethical at best and fraudulent at worst if you present conclusions without telling your audience about known errors and biases that contaminate those conclusions.
bdgwx says:

Who said ‘better’? The point I am making is the mathematics doesn’t add anything important to public debate. You can recognize that right?
Even CO2isLife seems to have learned that the Moon rotates about its center of mass.
Luckily, people à la hunter, Swenson, Robertson, ClintR, DREMT and a few others never had, don’t and will never have anything to do in any lunar mission.

Where is ren?
He promised us a harsh winter in Europe, 30 cm snow in Berlin, etc etc.
We had 15 cm snow, now all away.
Central Germany had more snow, due to the collision of two huge wind fronts just above it: cold, sometimes glacial from NNE (Arctic import), versus mild, sometimes really warm from SSW (Africa import).

Binny,
How are your own forecasts going? Have you worked out how to forecast future climate states?
The IPCC says it is not possible to forecast future climate states, but of course you know better, dont you?
Maybe you could just pretend that CO2 causes heating, and project past temperature trends into the future. If that seems silly, you could just threaten anyone who disagrees, with extermination or lingering death by incurable disease!
You really are a strange delusional chappie, eh Binny.
Flynn
I have always pretended that putting CO2 between the Sun and a thermometer increases the temperature indicated by the thermometer.
How could it be possible to doubt about such definitive evidence?
Binny,
Who is Flynn? Why are you fixated on him (or her)?
As to your last somewhat incoherent sentence – maybe you need to express yourself in another language. Have you considered becoming fluent in English?
The Republican state government of Texas refused to believe the warnings that climate change could bring extreme cold as well as extreme heat.
They are now stuck in -10C temperatures with power and water systems that dont work.
Vote Republican!
If something is understood, it can be modeled. That is what defines truly “settled science.”
Let’s Review 50 Years Of Dire Climate Forecasts And What Actually Happened
https://www.zerohedge.com/political/lets-review-50-years-dire-climate-forecasts-and-what-actually-happened
Only fools believe the predictions of climate scientists. They are literally the laughing stock of the academic community. The only reason it exists at all is because they have the media and liberal academia covering for them, and the government funding them.
Imagine a lawyer using those articles in a court of law. The jury would be laughing their butts off by the end of the trial. The only way Climate Science survives is by avoiding cross-examination.

CO2, you have the wrong analogy. GHGs dont trap heat the way a battery traps electrical energy and can store it for later. GHGs trap heat the way extra insulation on your house traps heat during the winter. The way that closing a window traps heat.
Actually, that isn’t exactly correct. The one and only defined mechanism by which CO2 can affect climate change is through the GHG Effect. CO2’s contribution to the GHG Effect is to impede the exit of LWIR between 13 and 15µ from the atmosphere. Studies I’ve linked to this site demonstrate that CO2 slows the exist of LWIR from the atmosphere by a few milliseconds, not hundreds of years, milliseconds. To complicate this issue, LWIR of peak 15µ has a black body temperature of -80C°, so the GHG contribution is to prevent the atmosphere from falling below -80C°, it doesn’t actually warm anything. CO2 thermalizes LWIR between 13 and 15µ to a temperature of -80C°. That can be seen using Modtran and how the Stratosphere cools to -80C°, and not much lower.
Oooops, that should say 13 to 18µ peak 15µ LWIR. That is the quantum physics supporting the CO2 GHG Effect.
“To complicate this issue, LWIR of peak 15 has a black body temperature of -80C”
Once again, this is COMPLETELY WRONG! BACKWARDS!
Turn that around and you get a true statement. A black body with a temperature of -80C as a peak of 15.
But ….
* A non-black with a temperature of -80C could have a peak at 15 … or at 14, or at 10, or at 20. Or pretty much anywhere.
* A non-black with a temperature of -80C … or -100C or -40C or +80C could have a peak at 15.
You simply are not understanding the physics here at all. The location of the peak for a non-blackbody tells you (almost) nothing about the temperature. It instead tells you about the quantum mechanics of the materials involved.
All conservatives can do is say “we told you so,” but that is no consolation. Conservatives hate to see Progressives lead this country to ruin.
Royce Pierce told Newsweek he owes electric company, Griddy, $8,162.73 for his electricity usage this month. He said that’s a massive increase from his usual $387 bill.
https://twitter.com/katandtonyT/status/1362460057447849987?s=20
Maybe AOC can crowdsource money to pay Texas’ electric bill. BTW, why don’t I hear Texas crying for a Federal Bailout? And why isn’t Biden falling all over himself to throw money at Texas for making idiotic decisions?
This is what you get when you allow demand pricing.
Typical American attitude. A system designed to favour the rich, who then tell the rest “F*ck you, Jack. I’m all right.”
Simple Question ET, what would the cost of electricity be in Texas if they had relied on safe, clean, reliable Coal and Nuclear like China is doing?
The one and only reason Texas is in the mess they are in is because they trusted people like you. Now all Conservatives can do is say “I told you so.” Right now Biden is helping Iran get a nuclear bomb. When they eventually get it, and start WWIII, saving “I told you so” won’t help much. Millions will die. Right now Biden is tolerating China putting Uygers and Fulong Gong” members in labor and concentration camps. Eugenics was supported by Progressive “Scientists.” Where do you think this is all headed?
Coal is more expensive than anything except nuclear.
Their gas pipes froze up and their nuclear plant shut down because they were too tight to invest in heaters for their pumps.
The underlying problem is that the Texas state government allowed their utilities to be run for maximum profit, with minimum investment. This left them with no margin for high loads and fragile equipment which couldn’t cope with cold weather.
Northern Ireland had -10C night temperatures a few weeks ago for similar reasons, a very Southerly Rossby wave, and everything kept working.
Why can’t Texas manage?
Entropic man
I will agree that Texas has problems with greed. Someone wants to pocket all the money rather than make sure they have reliable power.
Your point on the cost for power would not matter. If I needed power I would rather pay a little more than freeze or overheat. Wind, as it is now being developed with no storage capability, is most unreliable. It would not matter if it cost a dollar a megawatt hour if it does not provide full service.
Whoever is in charge of the power plants needs to maintain them like airlines maintain jet planes. You don’t want a jet to fail when needed most (in the air). Texas can ask their counterparts in colder climates how to maintain equipment in colder temperatures.
Here is an intelligent comment from WUWT. If demonstrates the problem with both wind and gas. Storage capacity.
From WUWT comment: “What happened is that there was a lack of storage for both renewables and gas. Wind was offline due a lack of wind and and lots of blade icing. Gas went offline due to everyone turning on their gas heaters, so no gas was available for the power stations. As far as I can see the Texas electrical mix totals went something like this for the 15th Feb
Wind . 30 gw installed 10 gw expected 5 gw online .
Solar 2 gw installed 0.5 gw expected 0 gw online (day only)
Gas … 35 gw installed 35 gw expected 15 gw online
Coal 15 gw installed 15 gw expected 15 gw online
Nuclear 11 gw installed 11 gw expected 10 gw online
(Note: a total of 25 gw dropped off the grid during the freeze.)
So wind and solar COULD have alleviated this situation, if they were remotely reliable. But they are not reliable, so Texans froze.
Note that coal and nuclear were doing fine, because they have sufficient fuel storage facilities. While gas does not have so much storage, as it is expensive. And domestic gas usage went through the roof, depleting supplies to the power stations. But if gas had any incentive to invest in storage, it could. Meanwhile wind and solar make no effort whatsoever to construct backup storage systems, because they are hugely expensive and would make them totally uneconomic.”
Norman
” Gas went offline due to everyone turning on their gas heaters, so no gas was available for the power stations. ”
This is a bad joke, Norman.
Everyone knows in between (Tx’s gov included) that gas supply went down due to freezing wells and to the higher humidity of gas coming from hydraulic fracturing compared with ‘natural’ gas.
And that is the reason why so many people were freezing in their houses.
Please never trust in WUWT head/guest posts dealing with energy supply.
What is exceptionally correct is the lack of supply by windmills.
In Germany, winter normally is the best time for wind energy. But the amount for 2021 was far worse than 2020, as you can see here (in TWh):
Year 2021 2020 (amounts for Jan 1 – Feb 19)
Total 20 vs 29
Onsh 16 vs 24
Offsh 4 vs 5

The purpose of my copy of a WUWT post was the major point. I did not research if heating use of natural gas created a shortage so I can’t verify that one. But that is not the point. His point was that wind has no storage capacity. It is a stupid thought process just to build a bunch of windmills and not have any means of power storage.
https://freerepublic.com/focus/f-news/3935690/posts?page=4
The second graph in this link clearly demonstrates the point. Wind can easily be the reason for the blackouts and loss of power. On Feb 8 wind was generating almost 20,000 Megawatts of power and the natural gas plants were very low. Then when needed (a capacity of 30,000 Megawatts) the wind was gone. Yes all the other sources of power went down but NONE went down like wind. If Texas had 30,000 extra capacity electrical production besides wind they would not have had a problem even with some power going off line. Nothing goes off-line more than wind which can give you 30,000 megawatts one day and then just a few thousand a week later. It is not intelligent to continue investment in wind energy without investing in some form of electrical storage. Wind alone is terribly unreliable when you need it most.
With weather patterns the super cold and super hot are a product of a stubborn high pressure system. These do not produce winds within the extended high pressure. Very high or low temperatures with these systems and no wind. Many people know this but they just keep spending more on wind knowing it is not there when needed. This is very stupid thought process.
Bindidon
Agreed.
By world standards Biden and the Democrats are well to the Right of centre and the Republicans are even further Right.
I stopped laughing at their distorted view of the world years ago, but it can still raise a smile.
Dr. Spencer, bdgwx may have provided you a way to expose the Climate Change Hoax in an undeniable way that anyone with basic math skills could understand.
bdgwx uses regression analysis and cherry-picking time periods to identify a positive slope to support his preconceived conclusions. That is how typical climate science works. Torture the data until it gives you the answer you want. Cherry-pick, misrepresent, and distort the truth to make your case.
How you can use that data to tell the truth:
1) Replace the Average with Median, which reduces the skewing caused by outliers and gives a more true representation of what can be expected
2) Convert the data from a time series to a distribution, and show where the current or recent data is to the median and the mean
3) bdgws loves to use the recent spike in temperatures to distort the regression, to address that, identify what % of the data falls below that temperature, and compare it to earlier periods in the time series. That way you can show that the recent spike was an outlier and represents just a small % of the period, and that earlier periods were at that level as long as well
4) bdwgx loves to distort regressions and their interpretations, so use his deceptive tactics to understand how to present the data in an honest manner, one that accurately defines a trend the way they are intended to be interpreted.
5) Rolling Medians or rolling averages
6) Rollings regressions to show how bggwx’s coefficients swing from + to – depending on the time period
The R-Sqr is the explainatory power of a regression. The regressions bdgwx uses have very very very low R-Squareds, so you can torture the data to get any answer you want. To refute such dishonesty, you have to explore different ways to present the data and desciles, medians, distributions, and ranges is how you do it.
CO2isLife said: bdgwx uses regression analysis and cherry-picking time periods to identify a positive slope to support his preconceived conclusions.
I’m not the one selecting the sites and time periods. That is your doing. And I’ve warned you repeated about it.
CO2isLife said: Replace the Average with Median, which reduces the skewing caused by outliers and gives a more true representation of what can be expected
Sure. We could use Tukey’s biweight mean or similar approach, but I don’t think you’re going to get the result you’re looking for.
CO2isLife said: bdgws loves to use the recent spike in temperatures to distort the regression,
I have done no such thing. All I do is plug in ALL of the values and let LINEST do its work. In fact, if anything by starting the regressions at high and ending at lows as you’ve requested me to do we are actually slightly distorting the regression in the negative direction.
CO2isLife said: The R-Sqr is the explainatory power of a regression.
Sure. Specifically it is how close the data clusters near the regression. Low noise high R^2. High noise low R^2. But, as I’ve said repeatedly, that is different than the standard error of the slope of the regression. These are two different metrics that are trying to conflate.
CO2isLife said: The regressions bdgwx uses have very very very low R-Squareds
Given the noise in the data I actually thought some of them were quite high. Regardless I don’t think you’re going to get a lot of support with your argument since the many of these trends have slopes that are several multiples of the standard error. Even Dr. Spencer’s R^2 in this very post at 0.096 is quite a bit lower than the R^2 of most of the sites you had me look at.
Bottom line, if there is a true up-trend in the data the early data should fall 1 or more standard deviations BELOW the mean, and the current data should be falling 1 or more standard deviations ABOVE the mean. Thinking through that however, a great way to represent a trend would to graph the T-Score/Z-Score over a time series. A trend by definition will have the recent data above the median and the distant data will have to be below the mean. The mid-point of the time series should fall very close to the median and/or mean.
Get a Grad Student to convert the Temp Data to T-Scores,and map it out on a time series. That is the best way to demonstrate an uptrend.That way you can standardize all the graphs and create an apples to apples way to compare different stations.

CO2isLife said: Bottom line, if there is a true up-trend in the data the early data should fall 1 or more standard deviations BELOW the mean, and the current data should be falling 1 or more standard deviations ABOVE the mean.
Patently False. If there is a true up-trend in the data then the slope of the linear regression trend will be significantly higher than the standard error of that trend. For UAH TLT the trend is +0.1375C/decade +/- 0.0066 with an R^2 of 0.46. And here are the z-scores for different warming trends.
+0.1375C/decade : 0
+0.1309C/decade : -1
+0.1243C/decade : -2
+0.1177C/decade : -3
+0.1111C/decade : -4
+0.1045C/decade : -5
What this means is that we have 99.9% confidence that the actual warning rate is at least +0.1177C/decade. And with 99.9999% confidence we know the rate must be at least +0.1045C/decade. All of that with an R^2 of “only” 0.46.
BTW…the UAH TLT mean is -0.08 with an SD of 0.25. The 13m centered means at the beginning and end are still > 1 SD below and above the mean. Just saying…
Here is an example of how to lie with a regression. If I play with the data of this chart I’ll be able to find a positive slope to make my case that temperatures are warming at the Toledo Blade Site. It of course would be a lie, but I could torture the data to support my lie.
Toledo Blade (41.6500N, 83.5333W) ID:USC00338366
https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=USC00338366&ds=14&dt=1
This is what a true uptrend looks like. It is a continual series of higher highs and higher lows, no ifs and or buts. The original data is far far far below the current data. If I run a regression it will have a statistically significant Beta/Slope and a very very very high R-Squared. You will find no temperature graphics that produce the regression numbers like CO2 does. So when bdgwx posts regression stats, just remember what a true up-trend looks like, and trust that your eyes aren’t lying to you.

CO2isLife said: Here is an example of how to lie with a regression. If I play with the data of this chart Ill be able to find a positive slope to make my case that temperatures are warming at the Toledo Blade Site.
The trend is actually 0.000C/decade +/- 0.020. The slope has no statistically significant slant either positive or negative. We say that the slope is consistent with a flat trend.
bdgwx, run your regression stats on the CO2 data. You will discover that it has a very very very high R-Squared. You will find that the early data is way below the current data. You will find that it has a series of higher highs and higher lows. You will find that the current data is in the right tail and the early data is in the left tail. That is how you define an uptrend, not with a regression that has an R-Squared of 0.00.
BTW, this is a serious question. How are you determining the statistical significance of the slope? What time period are you using to calculate the standard deviation of the slope? How did you calculate the standard deviation of the slope to determine that it is statistically different from 0.00?
CO2isLife said: How are you determining the statistical significance of the slope?
Most people consider a result to be statistically significant if it meets the 2-sigma or 95% confidence intervals. Linear regressions provide a standard error for the slope term. We subtract off 2 SD’s from the slope and say that we have 97.8% confidence that the slope is at least that amount.
CO2isLife said: What time period are you using to calculate the standard deviation of the slope?
I’m using whatever time period you tell me. If you haven’t specified than I do the entire population. So for Toledo Blade it is 1880 to 1996 or 117 years. It is also important to note that I do not ever cherry-pick years from the population. I run LINEST with every sample in the population regardless if it is a record low or high year. Literally every value is plugged in.
CO2isLife said: How did you calculate the standard deviation of the slope to determine that it is statistically different from 0.00?
The linear regression technique provides this value for you.

Excel’s LINEST function drops this in R2C1 of the output.
Some people seem to lack the necessary experience in puncto ‘manipulation with charts’.

J.-P. D.
Thanks Bindidion, that makes my case perfectly. CO2 and Temperatures aren’t linearly related, yet you are trying to demonstrate a linear relationship. If you replace ΔCO2 with ΔLog(CO2) or ΔW/^2 you would understand why your graph doesn’t implicate CO2.
It also shows a very linear uptrend in temperatures which I have proven simply doesn’t exist, and am now up to 340 stations that show no long-term uptrend in temperatures, and in fact, many show a down trend.

https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=USC00338366&ds=14&dt=1
Your analysis fails for multiple reasons:
1) It demonstrates a linear relationship with CO2 and Temperatures
2) It doesn’t relate Temperature to ΔW/M^2 or Δlog(CO2)
3) The temperature data isn’t supported by station data when controlled for CO2 and the UHI Effect
4) Your relationship totally breaks down when applied to the Holocene as a whole, you simply cherry pick a very short period of time to make your case
5) Your CO2 shows very little and consistent variability, your temperature does not
6) Your R-Squared will still be very low
7) Your temperature data doesn’t match UAH Satellite Data
8) You obviously didn’t get the memo from bdgwx, he is claiming that the CO2 drives temperature model is a complete myth

You seem to be a kind of German elementary school teacher.

Binny,
As you say, it is easy to make things matching other things. CO2 alarmists do it all the time.
These are the sorts of people who warm themselves in front of a fire, and convince themselves that the CO2 from the fire creates the heat!
They have created a graph which shows that more CO2 correlates nicely with more heat!
Dimwits, just like yourself.
Superdimwit Flynn
You are, as usual, blind on one eye.
And here you even manage to show us how stubborn you are:
” These are the sorts of people who warm themselves in front of a fire, and convince themselves that the CO2 from the fire creates the heat! ”
I can’t recall anybody writing such dumb stuff – even your friends-in-denial ClintR and Robertson don’t go down that low mentally, and that’s saying something!
Yeah, Flynn! Intelligent sarcasm and the tendency towards trivial sayings are not good friends.
J.-P. D.
Nice try Bindideon, but you can’t get away that easy. You have posted all the evidence I needed.
1) You demonstrated that CO2 and Temperature is the focus of Climate Change, which is denied by bdgwx once I demonstrated the absurdity of his claims
2) You posted a graphic that make is undeniably clear what an uptrend looks like, as opposed to the graphics that bdgwx tortures to identify a LINEST + slope, everyone understand that your CO2 and Temperature charts displays two clear uptrends, whereas the ones bdgwx claims are uptrends look nothing like the graphics you posted. No one denies the uptrends in your graphic
3) You demonstrated that the published global temperature trend is 100% inconsistent with the now 340 locations that I’ve identified that show no warming trend. In fact, I am having trouble finding any sites with a clear uptrend to them
Once again, thanks for posting all the evidence I needed to refute both you and bdgwx. You and bdgwx need to make sure you have your stories straight.
https://www.woodfortrees.org/graph/esrl-co2/scale:0.008/offset:-2.7/plot/hadsst3gl/from:1958/mean:36

Couldn’t you manage to stop your trivial stuff?
Why don’t you have the humility and the courage to visit the people who do the work you so superficially discredit, denigrate and distort, and REALLY begin to learn what they do?
Why do you write all this unscientific nonsense while comfortably and cowardly keeping hidden behind a pseudonym?
bdgwx and I we use pseudonyms too; but as opposed to you, we don’t discredit and denigrate the work of other people.
J.-P. D.
1) I made no such claim.
2) You picked those graphs. Don’t try to pin your cherry-picking on me. I’ve been telling you over and over again that you need to look at the global mean temperature and oceanic heat content. And the reason why you able to more easily see the uptrend in the global SST and CO2 graph is because both have far less noise than the 2m temperature at a single site.
3) First…We know for a fact that several of your 340 cherry-picked sites actually do show warming with some of them far exceeded the global rate. Second…340 sites is only 1% of the GCHN-M repository and because those 340 sites are included in spatially averaged global temperature measurements that necessarily makes them consistent with global mean surface temperatures. And since SSTs are also an input into the global mean surface temperature it only makes since that they too are consistent with it.
A very good research work would imho be to find out the reasons for
– the difference between the effect of the respective polar vortex weakenings above Northern America and Europe;
– a possible increase of these effects in Northern America.
John Christy’s recent paper about extreme weather patterns in CONUS could hardly have been better challenged than by what is happening in Texas these days.
Any client for a PhD in Huntsville, AL?

1) I made no such claim.
Which is it? CO2 does or does not cause climate change and is the most significant factor causing climate change? State your position.
2) You picked those graphs. Don’t try to pin your cherry-picking on me. I’ve been telling you over and over again that you need to look at the global mean temperature and oceanic heat content. And the reason why you able to more easily see the uptrend in the global SST and CO2 graph is because both have far less noise than the 2m temperature at a single site.
Not a single graph I identified shows an untrend anywhere close to the composite global temperature. None. The global mean temperature is a composite of all other stations is it not? I challenge you to find any stations that even come close to the uptrend identified in the composite. Find a single one. I challenge you. I’ve keep finding countless ones that show no trend and have yet to find one that show a clear trend anywhere near that global composite. BTW, land and sea temperature show widely different slopes, the difference of which can’t be caused by CO2
3) First…We know for a fact that several of your 340 cherry-picked sites actually do show warming with some of them far exceeded the global rate. Second…340 sites is only 1% of the GCHN-M repository and because those 340 sites are included in spatially averaged global temperature measurements that necessarily makes them consistent with global mean surface temperatures. And since SSTs are also an input into the global mean surface temperature it only makes since that they too are consistent with it.
None of them show warming in an uptrend, none. Using Bindidion’s example of a real uptrend as a standard, none of the graphics I posted come close to an uptrend. None, a LINEST positive slope does not represent an uptrend is the R-Squared is 0.00. Every stat book ever published will agree with me on that. BTW, mixing and matching completely different data sources into a single composite does nothing but increase the error you will get in the final version. Any real science would identify the most accurate way to measure and use it. Mixing garbage with accurate data still leaves you with garbage. Once again, how does CO2 cause a greater slope over land than sea? It can’t.
1. CO2 is a contributing factor to the increase in the global mean temperature and oceanic heat content. That is the position supported by the abundance of evidence. I accept it.
2. False. The counter example I will use is Vilinius LH000026730. From 1880 to 2020 it exhibited a warming rate of +0.162C/decade +/- 0.020. The global temperature over that period is +0.080C/decade +/- 0.003. Vilinius was on your list.
3. Same as #2.
I forgot to include my global mean temperature reference.

Also, I’ve challenged bdgwx many times to identify a station that matches the Global Aggregate’s uptrend. I’m up to 400 stations that show no warming, and honestly haven’t found any that come close to the Global Aggregate. Well, guess what? NASA GISS Found One. Remember what the hypothesis was. If you control for the UHI and Water Vapor you will find no warming. I’ve posted many stations showing no warming that fit those requirements. Now, how did NASA GISS address this issue? Did they choose to highlight a station that fits those requirements? Nope, they literally chose Central Park NY, a location that is synonymous with the Urban Heat Island Effect, and it is surrounded by water. That isn’t a joke. Look at the one they chose to highlight that looks a whole lot like the chart above it on the front page.
https://data.giss.nasa.gov/gistemp/
Here is the Global Graph:

Here is the chart they choose for the Front Page
https://data.giss.nasa.gov/gistemp/link_stations.png
Note, they chose not to feature West Point which would have been a more appropriate site.
West Point (41.8450N, 96.7142W) ID:USC00259200
https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=USC00259200&ds=14&dt=1
As of right now there are only 14 stations of the 27,000+ in the GHCN-M inventory on GISTEMP’s exclusion list. West Point is part of the GISTEMP’s global mean temperature calculation.
I’m kind of curious bdgwx, I’ve posted two locations basically at the same latitude and longitude, and yet one shows a strong uptrend clearly due to UHI and WV, and one that is largely sheltered from changes in UHI and WV that show no warming. Why in the world would you include one station that is known to have corrupt data and one that doesn’t? What benefit does it provide to include garbage data with accurate data. Why would you include both? What is the logic to intentionally corrupting the data other than to present a false impression of warming?
I have no idea what you are talking about. First, West Point USC00259200 is a thousand miles away from Ny City Central Park…ya know…one being in New York and the other Nebraska and all. Second, who said anything about corrupt data?
Understanding an Uptrend:
New York Cntrl Pk Twr (40.7789N, 73.9692W) ID:USW00094728
https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=USW00094728&ds=14&dt=1
Central Park, a location synonymous with the Urban Heat Island Effect and surrounded by water, basically the worst location to identify true warming, show a clear up-trend.
1) It is a series of higher highs and higher lows
2) The T-Scores of the early data would be the left tail and the current values would be the right tail
3) Recent lows are well above even the highs of the earlier time period ranges
4) It would have a solidly statistically significant coefficient
5) It would have a reasonably high R-Squared, but I bet it is still pretty low
6) The early range centers around 11 and the current one centers around 13.5, a full 2.5C°
7) Recent highs are well above the highs of the range set early in the data
8) Range borders would be two parallel uptrending lines that enclose the vast majority of the data
Clearly NY Central Park is an uptrend, and clearly, it is the worst possible example of a station to reflect true global warming. It is the epitome of stations to highlight the corruption of the UHI and WV, not CO2’s impact on temperatures.
Here is a location that is basically the same location, but removed from the UHI and WV, and it is a far better location to highlight the impact of CO2 on temperatures.
West Point (41.8450N, 96.7142W) ID:USC00259200
https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=USC00259200&ds=14&dt=1
As a I said above West Point, NB and NY Central Park aren’t even remotely in the same location.
60 miles on a global scale is the same location.
https://www.google.com/maps/dir/West+Point,+New+York/New+York/@41.0515397,-74.2337183,10z/data=!3m1!4b1!4m14!4m13!1m5!1m1!1s0x89c2cd92fd52d37f:0xba42d6d4455b94cb!2m2!1d-73.9559721!2d41.3914827!1m5!1m1!1s0x89c24fa5d33f083b:0xc80b8f06e177fe62!2m2!1d-74.0059728!2d40.7127753!3e0
West Point is a very short train ride. It is basically the same distance to the end of Long Island.
Facts are, the location is close enough, and CO2 is identical in both locations, so once again, why is there a temperature trend that is extremely different? The only reason NYC is increasing and West Point isn’t is because NYC corrupts the data with the UHI effect.
What is your explanation as to why the locations have dramatically different trends, and why justification is there in including them in a composite knowing that one if corrupted?
CO2isLife said: 60 miles on a global scale is the same location.
West Point USC00259200 is in Nebraska. Nebraska is west of the Mississippi River. That is 1200 miles from New York Central Park.
CO2isLife said: Facts are, the location is close enough
On what planet is 1200 miles about as much as 60 miles?
CO2isLife said: and CO2 is identical in both locations, so once again, why is there a temperature trend that is extremely different?
Because CO2 isn’t the only thing modulating the temperature.
CO2isLife said: What is your explanation as to why the locations have dramatically different trends, and why justification is there in including them in a composite knowing that one if corrupted?
Neither are corrupted. GISS uses both and pretty much all of the 27,000+ GHCN-M stations because they want to get the best possible estimate of the global mean temperature.
Good catch on West Point:
West Point (41.3906N, 73.9608W) ID:USC00309292
https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=USC00309292&ds=14&dt=1
Current temp is below the level of 1920
Almost all data falls below the level of 1920
Unsdjusted Data shows no warming at all, only the adjusted data does
Compare West Point to NYC and there are clear difference, differences that can’t be due to CO2. As a reminder, this is what an uptrend looks like.

Post the linear regression trend for each site. If you don’t I will.
CO2isLife
I am not sure what you are trying to demonstrate. You can look at Roy Spencer’s temperature graph and see a warming of around 0.8 C in 42 years. The troposphere where he is getting his values would not warm unless the surface did as well, the surface should warm a little more than the atmosphere above as the atmosphere is generally a little cooler than the surface.
https://data.giss.nasa.gov/gistemp/graphs_v4/
The near surface in the same time frame went up around 1.17 C which is kind of matches Roy Spencer’s graph of higher level Troposphere temperature.
I do not think you found a smoking gun in your data quest. A lot of what you claim is no warming looks like warming to me. Higher highs and higher lows near the end of many of the extended temperature graphs. I believe bdgwx did actual trend lines through lots of your data and found warming. You may not be able to tell with the “eye balls” it may require a trend line to determine the actual direction of the temperature graph.
It’s interesting again to see that NOAA, which is repeatedly discredited by ‘some’ commenters, continues to publish a La Nina-oriented evaluation of NINO3+4:

do the inverse.
Note that last week, the red bar in the JMA picture was only at 10%.

It is possible that the winter max is in for the year.
From the (very conservative) French newspaper ‘Le Figaro’
In Texas, after the cold snap, five-figure electricity bills
Faced with extreme temperatures, many residents received prohibitive bills, up to $ 17,000.
Texas is in fact the only state whose energy distribution network operates only state-local, and its electricity market is completely deregulated.
Many homes have contracts whose monthly price varies according to demand, and the latter exploded with the cold snap. With the extreme weather conditions, energy use has skyrocketed, pushing wholesale electricity prices to over $ 9,000 per megawatt hour, compared to a seasonal average of $ 50 per megawatt hour.
A resident of Dallas has reported to the local channel WFAA to have seen his bill go to $ 17,000 against $ 660 in normal times for his main residence, his outbuilding and his office.
A couple has to pay 3,800 dollars for 15 days when their bill for the whole of 2020 was 1,200 dollars. Another could see on the application of its operator, Griddy, having to pay 573 dollars for the single day of Monday.
Furious, many residents of the “lone star state” tweeted the photo of their bill to their governor, Greg Abbott, as well as their senator Ted Cruz, who took refuge in a seaside resort in Cancun, Mexico in the midst of chaos.

NOrman: You can look at Roy Spencers temperature graph and see a warming of around 0.8 C in 42 years.
Dr. Spencer’s graphic doesn’t even attempt to correct for the UHI and Water Vapor. If you parse Dr. Spencers data for Polar or Ocean Temperatures, areas partially controlled for the UHI Effect, you will see that you get widely different temperature trends. Same for the N and S Hemisphere. CO2 is 415 all over the globe, so CO2 can’t cause the differences in slopes of UAH Temperature graphics. I don’t disagree that the globe may be warming, my focus is providing evidence that it isn’t due to CO2. Simply find a desert location and you won’t find any warming over the past 100 years.
Here are over 400 sites with no warming uptrend. Unfortunately the link won’t post.
CO2isLife
They have actually measured the increase in DWIR from increased CO2. It is not much per year. 0.2 W/m^2 per decade. That would be 0.02 Watt/m^2 per year. Not noticeable and then many other factors can vary the temperature on a yearly scale like cloud variation and many others. On short term basis like yearly many things can affect the changes in temperature (volcanoes also). The AGW is a slow but steady slog up the path.
Also with the deserts, the CO2 will just increase the energy the surface receives. That energy can be used to increase temperature but it could also just increase convection and not show up as an increase in temperature at some locations.
Maybe I will look up some desert locations and see if I can determine zero warming.
I am not against your efforts but I do not think NOAA is intentionally creating false data by making a global data set using the individual reporting stations. They could be this deceitful and dishonest. It is always a possibility but I am not inclined to believe this is the case as this time.
CO2isLife
I was trying to make temperature plots from the GISS page in Arizona but I get “Not a valid station” (or close to that) error. I tried Phoenix, Yuma, Tombstone but no luck.
Norman: I am not against your efforts but I do not think NOAA is intentionally creating false data by making a global data set using the individual reporting stations.
Thanks Norman, but my point is that by combining Corrupted Data with non-corrupted data is something every scientist knows it is a worst practice. NASA GISS and others are the biggest Cheerleaders for CO2 being the culprit, and yet they choose locations like NY CIty to make their case.
This is my favorite desert location, but I have found many many more.
Alice Springs (23.8S, 133.88E) ID:501943260000

Where is this “corrupted” data that you are seeing?

0.10 C/decade for 1890-2019 (0.26 since 1979, Antarctic included), i.e. 1.3 C for 130 years.
Everybody will tell you: so what!
J.-P. D.
The data from Alice Springs is combined with NYC and NASA makes the claim that CO2 is the cause. Alice Springs shows no warming and isn’t subjected to WV or UHI, NYC is the standard location to demonstrate the UHI effect. By combining the two data sets together you get warming that is clearly not due to CO2. If you want to really define the impact of CO2 on the temperature you would eliminate stations like NYC, and use only stations that are controlled for UHI and WV. If you are going to use NYC, they should have a disclaimer that the warming is due to the UHI, not CO2.
I don’t care about combining datasets, UHI, or WV. I want to know where specifically you are seeing “corrupted” data.
Did you find a temperature series in the GHCN-M repository that was not readable at all? Is there a specific station for which the GISS station temperature plot tool does not work or return data?
Why would UAH need to correct for UHI and WV?
If you want to falsify the hypothesis that CO2 can effect the global mean temperature and/or oceanic heat content then here are some ideas.
– Show that there is no increase in the global mean temperature.
– Show that there is no increase in the oceanic heat content.
– In lieu of the above show that there is no cooling of the stratosphere.
– Show that CO2 is not active in the infrared spectrum.
– Show that all other agents sans CO2 can adequately explain the GMT and OHC trends during the contemporary era.
Since no one seriously advocates for any hypothesis in which CO2 is the only agent that can modulate the temperature on small spatial and temporal scales then your proposed test in regards to a specific site is useless.
bdgwx says:
1) Show that there is no increase in the global mean temperature
Done: I’ve identified many locations of various latitudes and longitudes that when controlled for UHI and water vapor shows no warming up-trend and no relationship to CO2
2) Show that there is no increase in the oceanic heat content
Done: CO2 and LWIR between 13 and 18µ won’t warm water, so CO2 can’t be the cause. What has warmed the oceans is the lower cloud cover that has been allowing more warming visible radiation to reach the oceans. The deep oceans are also warming, and CO2 and visible radiation can’t cause that warming. Lastly, the Hockeystick shows a dog-leg in 1902, ocean temperatures (Southern Hemisphere) doesn’t show a dog-leg, and there is a large difference between the N and S Hemispehre that can’t be due to CO2.
3) In lieu of the above show that there is no cooling of the stratosphere
CO2 would cause cooling in the stratosphere. Radiation rapidly moves energy out of the atmosphere. What CO2 will do is put a floor into the temperature of the stratosphere which is -80C°
That temp is consistent with the black body temp of peak 15µ LWIR
4) Show that CO2 is not active in the infrared spectrum
CO2 is absolutely involved with the LWIR Spectrum, specifically 13 to 18, peak 15µ LWIR. That wavelength is consistent with -80C° and will not penetrate or warm water. It is also the reason the stratoshoere or any later with CO2 won’t fall below -80C°. In fact even the Mars atmosphere, which is much thinner but largely CO2, barely violates that level.
5) Show that all other agents sans CO2 can adequately explain the GMT and OHC trends during the contemporary era
Prove there was warming. Alice Springs and the other 400+ locations I’ve identify don’t show warming. The better question is why can I find so many locations with no warming? Even if I agree there is warming, there had been a decreasing cloud cover over the oceans, and a greening of the N Hemi (more H20). BTW, simply look at the trend in the N vs S Hemi and look at the Pools. How can CO2 cause so many different trends in temperature?
I’ve not seen you post a global mean surface temperature product that is substantially different than any of the others.
I’ve not seen you post an oceanic heat content product at all.
Let me be perfectly clear here since there seems to be confusion on what global actually means. Global means the entire planet. One location is not a proxy for the entire planet. Nor is 400 or even 27,000 locations. Global means that all of the Earth’s 510e12 m^2 of surface area are accounted for. Global means that each of those 510e12 m^2 are equally weighted when computing the spatial average.
If you still do not understand what “global” actually means then please ask questions.
bdgwx: I’ve not seen you post a global mean surface temperature product that is substantially different than any of the others.
I can’t publish it, but you can easily recreate what I’ve done. Just go and download the data for the Locations I’ve identified that have a long-term history and a BI of 10 or less. What you will find is that the composite that you will create shows a wave, but no uptrend. It warms from 1880 to the 1930s-40s, cools through the 70s and 80s, and then warms again to current. The composite chart is a real spaghetti chart with some warming while others cooled, but when you equal weight them they form a wave, but certainly no uptrend. The one thing I didn’t do was create a grid to ensure that the stations have a reasonable dispersion. I have a feeling that the US is overweighted in my original work. My next time I will ensure that I’m not using redundant stations that are close by and tell the same story.
The important thing here is that you need to compute a spatial average that provides sufficient coverage of the Earth. Nick Stokes did this with just 60 stations so there’s no reason you shouldn’t be able to do something similar with your selections.

bdgwx says: The important thing here is that you need to compute a spatial average that provides sufficient coverage of the Earth. Nick Stokes did this with just 60 stations so theres no reason you shouldnt be able to do something similar with your selections.
Thanks bdgwx. I will do something similar but with the intentional selection of stations controlled for the Urban Heat Island Effect and Water Vapor. I will deliberately select desert stations in as many various locations as possible.
https://www.nationalgeographic.com/environment/article/desert-map
Think about that for a moment. If you had only select urban stations then your global mean temperature would have an urban bias. Likewise if you only select desert stations then your global mean temperature would have a desert bias. It would be better to select stations from all over the world that represents Earth’s climate diversity. And since Earth is 70% ocean you’ll want to heavily rely on island stations like what Nick Stokes did so that you do not underweight marine environments.
CO2isLife: “..controlled for the Urban Heat Island Effect and Water Vapor.”
UHI is more than adequately discussed in top post. How will CO2isLife control for atm. water vapor…exactly?
Selecting only desert weather stations will not necessarily accomplish that ideal, CO2isLife will have to do some proper hard, calculating work.
Deserts have relatively low precipitation, not necessarily low atm. water vapor. Desert weather stations are dry because they are located in regions of descending air. Owens Valley on the lee side of the Sierras and the Atacama Desert on lee side of the Andes are two examples.
As a detail hydrology example, look up recent same day June meteorology reports in Madison, Wisc. and Tucson, Ariz. For the same June day, they show precipitable water above Madison was 1.09 in., 119% of avg., Tucson 0.75 in., 93% of avg. Thus the avg. precipitable water above Tucson and Madison on a June day is about the same even though Tucson’s annual precipitation is less than one-third that of Madison’s.
To show I didn’t just cherry pick, look up meteorological records for June in Alouef in Algeria, firmly within the Sahara. Finding June water vapor partial pressures and converting to densities shows concentration of wv in Madison is around 20% less than Alouef. And the air temperature in Alouef is higher. This means radiation from the atm. above Alouef is more than likely higher than Madison. CO2isLife properly controlling for water vapor in June would have to pick Madison as a desert station over Tucson & Alouef.
Today, there are satellite TPW measurements that you can use instead of doing this old fashioned work; not doing the detail meteorological work means less learning about meteorology for CO2isLife who definitely needs to extend studies in the field.

The whole purpose of the experiment is to isolate the impact of CO2 on temperatures. Deserts are natural controls for the UHI and Water Vapor. The entire point is to demonstrate that if the globe is warming, it isn’t due to CO2. If cloud patterns change for non-CO2 related causes, yes, you can bet the temperature will change. If there are fewer clouds over the oceans, yes, they will warm, but it won’t be due to CO2. NASA uses the UHI effect and other non-CO2 related events to push the narrative that CO2 is the cause of warming. That is demonstrated by them literally choosing NYC as the graphic to highlight the warming and to support the global graphic they have right above it.
How do you plan to control for aerosols, solar irradiance, advective processes, albedo, and countless other factors that also modulate the temperature?
How do you go about determining why cloud patterns have changed?
bdgwx Says: Think about that for a moment. If you had only select urban stations then your global mean temperature would have an urban bias. Likewise if you only select desert stations then your global mean temperature would have a desert bias.
bdgwx, have you never run a controlled experiment? CIties grow over time. Cities are variable over time. Each year they build another road or building. Each year more heat trapping material is added to the system.
Deserts are basically constant. A sand dune is basically the same sand dune in 1,000 years. Yes it may change shape, but the physical properties are essentially constant. If you have an unchanging desert and a changing city, that is the differential you look for to tease out the impact of the UHI. You need changes, that is why they are called differential equations. ΔY = ΔX +b
If Δ = 0.00, then it has no impact on the model. To isolate the impact of CO2 on temperature you have to have as many factors with Δ = 0.00, and that is why you choose deserts, they are basically constant. You can find 5,000 year old papayrus in the Egyptian desert.
Your post mentions UHI and CO2. Which one are you trying to isolate here?
bdgwx, from your comment, “Your post mentions UHI and CO2. Which one are you trying to isolate here?”
I take it you haven’t run a controlled experiment.
1) The UHI is present in cities, it is not present if deserts, that is a differential between cities and deserts
2) CO2 impacts cities and deserts equally. The physics of the CO2 molecule is the same in a city as it is in a desert
Therefor, to isolate the impact of CO2 on temperatures you select deserts.
ΔCity Temperatures = ΔUHI + ΔH2O + ΔCO2 + ΔIrradiance + error
ΔDesert Temperatures = ΔCO2 + ΔIrradiance + error
CO2isLife claims: “1) The UHI is present in cities, it is not present i(n) deserts, that is a differential between cities and deserts”
Not doing your homework again I observe. I’ll offer CO2isLIfe could improve comments by knowing to control for The Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data showing UHI is inverted for cities located in already harsh environments such as hot deserts:
https://ui.adsabs.harvard.edu/abs/2014EGUGA..1613696L/abstract
“1) The UHI is present in cities, it is not present if deserts, that is a differential between cities and deserts”
The problem is that this is NOT the only difference. A few that spring to mind off-hand include:
Some desert regions are growing.
Some desert regions are shrinking.
Some desert regions are being irrigated to raise crops.
Global changes in weather patterns bring air with different temperature and humidity into desert regions than before (and into urban regions).
A desert is not a “controlled experiment” for these and other reasons. Changes due to UHI might well be the biggest difference, but that is certainly not the only change occurring. This might be called a ‘semi-controlled’ experiment.
CO2isLife,
City and desert temperatures are orders of magnitude more complicated than your trivial equations imply especially on on the short time scales you seem to be interested in. You are not conducting a controlled experiment by selecting only desert stations.
Tim et al.,
You lot have no idea of what an experiment is for, obviously.
Richard Feynman said –
“It doesn’t matter how beautiful your theory is, it doesn’t matter how smart you are. If it doesn’t agree with experiment, it’s wrong.”
You have no hypothesis – you can’t even describe a phenomenon which cannot be explained using basic physics. No hypothesis means you cannot even think about devising an experiment to see whether it agrees with your non-existent hypothesis!
No hypothesis, no experiment – no theory.
Just idle silly speculation. Probably from idle, silly, speculators.
Come back when you have learnt something about the scientific method.
“You have no hypothesis – you can’t even describe a phenomenon”
No, you can’t understand. There is a big difference.
“Richard Feynman said –”
How ironic that you can’t actually critique what I said, but do the most unscientific thing possible — appeal to authority.
Tim Folkerts says:
Some desert regions are growing.
Some desert regions are shrinking.

Changes due to UHI might well be the biggest difference, but that is certainly not the only change occurring. This might be called a ‘semi-controlled’ experiment.

Yes indeed the entire backdrop of climate change is upon an uncontrolled experiment. Thus temperature record changes really mean nothing either. We seem to agree upon the need for better controlled experiments rather than ignorantly assuming all these influences just average out.
But politically that is well known, the issue isn’t changing climate its issues of control, power, and influence in an ever changing world. That is one the constant we who have studied history understand well.
The point I think of Roy with this post is to highlight that the existence of UHI and its trends are separate complicated things that have not be adequately addressed in the surface temperature records. Getting UAH some funding to build a surface record based upon good analysis like what Roy published above would seem to be a better approach than having climate modeling groups control all those records and apply horse-blinder analysis to them. For the latter half of my career has been largely pro-bono stripping off the blinders and shining lights in the dark corners. I feel a kindred spirit with Roy on that.
We would do well to carefully heed the message in this post and its implications as to really how much genuine thought has been put into the topic of anthropogenic UHI temperature trends. Your comment above seems very supportive of that idea.
Tim,
You wrote –
“No, you cant understand. There is a big difference.
What is it you think I cannot understand? What is the big difference to which you refer?
I reiterate – if you cannot devise a hypothesis about some phenomenon which you cannot even define in any useful way, then all your talk of experiments is complete nonsense.
About as stupid as self proclaimed climate scientists who claim changing inputs to poorly written computer models are “experiments”!
As to critiquing, you have made a few assertions. Good for you! Cultist dogma, sure. Science, not so much. Who should people take more notice of? Richard Feynman, or your anonymous fellow cultists?
Try defining your stupid GHE. It would be a good start. Then you could propose a hypothesis, and check to see if it agreed with experimental results. Just waffling about speculative correlations only convinces the feeble minded.
There is a message there somewhere, Don’t you think?
“Try defining your stupid GHE. “
To quote myself, here is the hypothesis: “more greenhouse gases in the atmosphere lead to warmer surface conditions than a similar planet with less greenhouse gases”
“check to see if it agreed with experimental results”
1) CO2 is increasing and temperature is increasing. That agrees with the ‘experiment’ underway on earth.
2) The average temperature of earth (measured from the outgoing IR flux) is ~ 255 K. The surface is warmer than 255 K. Another experimental result.
And one step further. Basic physics theories that dates back a century explains those two experimental results quite reasonably. The 1st Law of thermodynamics. Thermal Radiation. Convection. Quantum mechanics of CO2.
A hypothesis.
Agreeing with experiments.
Consistent with established theory.
Bill I agree with a lot of what you say. There is plenty of common ground to be found. Too many people get locked into one view and are not willing to look farther.
I agree there will never be a “control” available in the way most people think of a “control” for an experiment — no second earth where everything was the same until say 100 years ago, but where CO2 was kept at, say, 300 ppm.
That does not mean that temperature changes “mean nothing”. Temperature HAS changed. So it is a reasonable scientific question to ask “why?”. Things change for reasons. Even without a perfectly controlled global experiment, it can be possible to tease out reasons (with varying degrees of certainty).
As for motivations, there are of course many. Some are purely interested in the science. Some are purely interested in power. Most are somewhere in between.
Tim,
If you cannot test your hypothesis experimentally, it remains speculation. In your case, you cannot even provide a testable hypothesis.
End of story. Speculate away.
Given that you don’t seem to know why temperatures change, I am not surprised that you find the whole scientific method somewhat baffling.
Maybe you should try fishing or stamp collecting. Science seems to be a bit beyond you.
“If you cannot test your hypothesis experimentally …”
There are many ways to test something. For instance, I cannot pick up my house (and no one has ever picked up my house), but I can still be 100% sure of the hypothesis “if I did somehow pick it up and let go, it would fall”. By examining many related examples (dropping other objects near my house, watching other houses fall in other places, seeing the moon ‘fall’ toward the earth) I can understand how gravity works. I can know that my house would also fall without ever testing that specific hypothesis .
Similarly, I can shine IR light through CO2 and see how it get absorbed. I can study how winds and ocean currents work. I can study how climate has changed in the past. I can look at the temperatures of other planets. All of these related examples help test the hypothesis that “more greenhouse gases in the atmosphere lead to warmer conditions than a similar planet with less greenhouse gases.”
Now I grant you, climate is more complicated than falling. The certainty is less. But we can still know a lot about climate without needing a second otherwise identical earth with a different amount of CO2.
“In your case, you cannot even provide a testable hypothesis.”
I just did.
Tim Folkerts says: ”Similarly, I can shine IR light through CO2 and see how it get absorbed.”
————————
Indeed you can Tim. However one has to consider where its getting absorbed. Obviously the atmosphere absorbing energy is going to warm it and in the first layer absorp-tion its obviously a contributor to surface climate. If I rob Peter to pay Paul according your logic I can claim that as evidence I paid Peter.
“Obviously the atmosphere absorbing energy is going to warm it and in the first layer absorp-tion its obviously a contributor to surface climate.”
That sounds like a good conclusion and an explanation for surface warming.
“If I rob Peter to pay Paul according your logic I can claim that as evidence I paid Peter.”
I have no idea what analogy you are trying to make here. You would need to clarify.
“Peter” = ??
“Paul” = ??
“money” = ??
“getting robbed” = ??
Tim Folkerts says:
”That sounds like a good conclusion and an explanation for surface warming.”
==============
Its a good explanation for some of the warming in a single layer model. A warm surface will indeed warm the atmosphere by convection and in the presence of water and greenhouse gases by both evaporation and radiation.

=================
It means if I steal heat from the first GHG layer in the atmosphere to warm the second does that mean I further warmed the first layer too? What AGW zealots like to overlook is the implications of their logic. Obviously GHGs absorb energy from the surface or that energy would end up in outer space. It seems so logical to you that it also pays Peter after you robbed the heat from Peter to pay Paul.
So you give a simple explanation (absorp-tion) and go no further in the explanation while you look around at everybody around you wondering why they don’t get it.
Bill, thanks for explaining your thinking. It makes it easier to understand your misconception, which is here: “it also pays Peter after you robbed the heat from Peter to pay Paul.” There is no ‘double accounting’ as you seem to conclude. The same energy is not “also” used to simultaneously warm two different regions.
Imagine no GHGs to start with (everything else being the same). The surface receives 240 J each each on each square meter (on average). And it adjusts its temperature to emit 240 J (on average). Everything is balanced.
Now suppose we add some GHGs that absorb, say, 1/2 of the outgoing energy. 120 J each second each square meter. Now a patch of surface absorbs 240J, emits 120 to space and emits 120 to the atmosphere. No double counting yet. You could say were are “robbing” space and “paying” the atmosphere.
But the energy getting absorbed by the atmosphere must go somewhere. It can also emit IR, so we might imagine it radiates 60 up and 60 down. It can do that. it is getting 120 in. No double-counting. You could say we are “robbing from deep space”, but we are putting it into the atmosphere.
But now the surface is getting 240 + 60 = 300. and only emitting 240. So the surface would have to warm up. Still no double counting. No energy being ‘used twice’. Just extra joules being “saved” by the surface until it is warmer and radiating more.
And now the atmosphere gets 150 …
The process does not follow discrete steps like this, but the final answer in this scenario is:
The sun provides 240 to the surface
The surface warms to emit 320: 160 to atmosphere and 160 to space.
The atmosphere absorbs 160: it emits 80 to space and 80 to the surface.
The only “stealing” is that for a while, the sun is providing 240 and space is getting less then 240. Both the surface and the atmosphere are stealing from space. And warming up.
It is, of course, much more complicated, but that is the gist. We could add another layer of atmosphere (“peter” and “paul”). we could change what fraction of energy is absorbed by the atmosphere. But the basic conclusion is the same. In a transient process, energy is “stolen” from space to warm the earth.
Tim, your emits 60 up and 60 down jive is just that. Bottom line is a net 60 watts of cooling was emitted from the surface and 60 watts emitted up from where it was first absorbed.
If there is to be an assumed rate of adjustment that should be established in a lab.
“Bottom line is a net 60 watts of cooling was emitted from the surface and 60 watts emitted up from where it was first absorbed.”
What do you mean by “net cooling was emitted”? A “net cooling” would mean the surface was getting lower in temperature, which never happened in the example.
The bottom line is that — at the beginning of my rather simplified example — only 180 W were being emitted to space and 240 W was being absorbed. There was a 60 W net WARMING of the planet. Energy was being sequestered. This pushed the temperature of the surface and the atmosphere up until once again 240 W was being absorbed and 240 W was being emitted.
Tim you are drifting far from my comment. My comment was essentially focused on you saying: ”I can shine IR light through CO2 and see how it get absorbed.” as essentially your only scientific rationalization for the greenhouse effect.
Fact is in looking at how heat gets into the atmosphere, CO2 is a very small part of it. Energy is absorbed into the atmosphere by a multitude of processes. Water vapor is one major one, water is another, and teensy bit from CO2.
Now agree that is how the sky gets warm and that the warmth of the sky has an effect on the warmth of the surface as does any two objects of possessed of temperature next to each other.
But when I gaze up at the sky I note that by far the warmest sky is socked in with clouds. Clear skies with just water vapor and CO2 are far cooler.
Clouds are estimated to make up 50% of the sky. And plenty of very talented scientists believe climate change is primarily affected via changes in clouds. Yet you ascribe to a theory that assumes over time clouds and water vapor can only change with changes in CO2. So why do you ascribe to that? The fact that CO2 absorbs energy like clouds and water vapor simply doesn’t seem sufficient support.
“My comment was essentially focused on you saying: “I can shine IR light through CO2 and see how it get absorbed.” as essentially your only scientific rationalization for the greenhouse effect.”
How do you conclude that? You took that one sentence out of paragraph listing many factors:
“Similarly, I can shine IR light through CO2 and see how it get absorbed. I can study how winds and ocean currents work. I can study how climate has changed in the past. I can look at the temperatures of other planets.”
CO2 is but one aspect of the interconnected web of science that leads toward an understanding of temperature and climate.
Bill, I agree that “Fact is in looking at how heat gets into the atmosphere, CO2 is a very small part of it. ”
But CO2 is a large part of how energy gets OUT of the atmosphere. Both inputs AND outputs are important.
“Yet you ascribe to a theory that assumes over time clouds and water vapor can only change with changes in CO2. “
No, I don’t (and I suspect very few people do)! I ascribe to a theory that CO2 is ONE PART of the picture. That by adding more CO2, less energy escapes to space, which causes warming. Clouds can and do change for many reasons on many time-scales in different parts of the globe. This also affects temperatures. I tend not to focus on clouds or feedbacks because my background is in physics, not meteorology. CO2 is ‘simple’ compared to many of the other factors that are ALSO important.
Or put another way, there is very little disagreement about the direct impact of changing CO2 from 300 ppm top 400 ppm. There is large uncertainty about what ADDITIONAL changes might occur as a result.
Tim Folkerts says:
”But CO2 is a large part of how energy gets OUT of the atmosphere. Both inputs AND outputs are important.”
————————–
I know inputs and outputs are important but I don’t see a case for CO2 controlling any part of the atmosphere in a way that would result in surface warming. The troposphere is delineated by the highest level of the atmosphere where water evaporates.
The stratosphere appears to be dominated by very small quantities of ozone. The mesosphere may be influenced by CO2 but I don’t think any scientist is trying to sell forcing from the mesosphere.
And lastly the papers that suggest CO2 affects lapse rates in the troposphere seem to be totally without validation.
Tim Folkerts says:
”Or put another way, there is very little disagreement about the direct impact of changing CO2 from 300 ppm top 400 ppm. There is large uncertainty about what ADDITIONAL changes might occur as a result.”
Well I don’t know anybody fretting over 1 deg C for a doubling of CO2 Tim. Disagreement can be low for many reasons. Not mattering is a big one. . . .and from a scientific point of view e.g. absorp-tion high in the atmosphere has to be dealt with in some way or the other.
I am a numbers and budget type guy. The planet reflects light off cloud tops and ice sheets and the atmosphere emits to space about 200 watts. None of this heat loss would exist if water vapor and CO2 didn’t exist.
So an equilibrium temperature of ~278.5k seems a no brainer without GHG. So if that is achieved without greenhouse gases then greenhouse gases might only be responsible for about 9.5k the vast majority of which would be water vapor.
The whole deal harkens little science my direction but an almost perfect duplicate of civil courts where usually at least one side hires a designated liar to represent them.
Bill says: “I am a numbers and budget type guy. … So an equilibrium temperature of ~278.5k seems a no brainer without GHG.”
You can’t be both a “numbers and budget” guy and a guy who goes with what “seems” right. If you think you can achieve a surface temperature of ~278.5K without GHGs (neither H2O nor CO2), then show the numbers. Present your energy balance and your assumptions. I suspect it will be harder than you think.
A temperature of 278.5 corresponds to
a) emissivity = ~1; albedo = ~0
b) emissivity = ~0.7; albedo = ~0.3
But each of these is half right. The true numbers are emissivity = ~1; albedo = ~0.3. Its tough to imagine how you will get to 278.5 without making at least one number wildly out of agreement with experimentally measured values.
Or perhaps you mean 278.5 is reasonable for a ball of rock like the moon, with no CO2 and no oceans and no clouds (but maybe a pure N2/O2 atmosphere). OK, that is not TOO far off; albedo close to 0 and emissivity close to 1. But when you say adding CO2 and H2O only needs to add another 9.5K, you are forgetting that you are now changing the albedo back toward 0.3. The reflective properties of GHGs (ie clouds) will cause cooling, so the IR properties of GHGS must be well over 9.5 K.
You can’t have it both ways.

————————–
Well you are ignoring some facts and posing a dilemma that may be no dilemma at all for at least 2 reasons.
1) almost all albedo is the result of condensing water vapor, forming clouds, falling as snow, and building ice sheets.
2) Stefan and Boltzmann equations have an emissivity parameter that does not in any way change equilibrium temperatures. All it does is change emission and absorp-tion rates. Remember that the idea it doesn’t is purely an artifact of looking at blackbody radiation only when determining equilibrium temperatures.
Since there may be some sea ice forming without going through the vapor stage there will be some albedo effects, possibly, depending upon non-blackbody radiation levels. But where sea ice forms is generally where the sun does not shine.

You cant have it both ways.

We live in a world where frequently there is more than one way to skin a cat. Assigning properties to GHG as if no other such way exists is simply wearing horse blinders. But perhaps you have read a major piece of work demonstrating no such other means despite the fact it exists right in front of your face.
“We live in a world where frequently there is more than one way to skin a cat.”
My point is that GHGs do indeed have two effects — a warming effect and a cooling effect. These are distinct effects due to distinct mechanisms. The net effect is close to the 10 K number you quote. But it is actually something more akin to 20 K of cooling (increasing the reflected sunlight from clouds, ice caps. etc) and 30 K of warming (blocking some surface IR from escaping directly to space). (There are other minor effects, but these are the big 2.)
The “greenhouse effect” (the second effect listed above) is about 30 K.
Tim Folkerts says:
”The “greenhouse effect” (the second effect listed above) is about 30 K.”
The greenhouse effect is about 10K. Its meaningless to divide it up into reflection (a form of absorp-tion/emission; and absorp-tion/emission if you can’t have one without the other. Its like saying your arm is a viable creature severed from the body.
Fact is Trenberth’s budget doesn’t provide adequate detail if you want to split every element up into parts of their net effect but he gladly does it for radiation, but refuses to do it for convection and transpiration.
But its an easy exercise to realize the big dog in putting greenhouse gases into the atmospshere is evaporation via convection. It puts a net of 97watts/m2 compared to radiations net of 23watts/m2. The AGW folks have the tail wagging the dog.
“The greenhouse effect is about 10K. Its meaningless to divide it up into reflection (a form of absorp-tion/emission; and absorp-tion/emission if you cant have one without the other. “
But you CAN have one without the other — because we are talking about different wavelengths. For example, white paint and black paint have about the same emissivity (for thermal IR) but vastly different reflectivity (for visible light). Or open water and ice, which have similar emissivity but very different reflectivity. Or clouds, which cool the earth precisely because they reflect visible light but absorb IR.

=================================
So are you just obfuscating here Tim. The net greenhouse effect is only 10K.
Stefan Boltzmann equations don’t change their equilibrium temperature by changing emissivity. Yet it appears you are suggesting it does.
I thought we were doing so well, but now we seem to be getting farther apart.
“So are you just obfuscating here Tim. The net greenhouse effect is only 10K. ”
You are going to have to define what you mean by “the net greenhouse effect” because it is clearly different from what I mean.
You seem to mean something like “any change from the temperature of a perfect blackbody (albedo for sunlight = 0.0; emissivity for thermal IR = 1) with a uniform surface temperature”. 278.5 K would be that temperature, so it is pretty clear that is where you are starting.
I mean (and I think most people mean) something like “the change in temperature due solely to the IR properties of the atmosphere).
So if we covered 10% of the earth’s surface with mirrors to reflect away sunlight and cool the earth, I would NOT consider that part of the “net greenhouse effect”. That is simply an effect of the albedo of the SURFACE, not an effect of the IR properties of the atmosphere.
Similarly I would not count UHI or changes in ocean currents part of “the net greenhouse effect”. I seems you would. And you are free to do that — we just need to acknowledge were are using words differently.
“Stefan Boltzmann equations don’t change their equilibrium temperature by changing emissivity. Yet it appears you are suggesting it does.”
Yes they do.
For a fixed 341 W/m^2 of absorbed sunlight (ie albedo = 0), the equilibrium temperatures for varying emissivities would be
1.0 278.5 K
0.9 285.9 K
0.5 331.2 K
For a more realistic 240 W/m^2 of absorbed sunlight (ie albedo = 0.3), the equilibrium temperatures for varying emissivities would be:
1.0 255.1 K
0.9 261.9 K
0.5 303.3 K
(That first number, 255 K is the number most often quoted as the no-greenhouse-effect “effective blackbody temperature” temperature).

This paragraph shows an odd mismatch between the sentences.
>> If you truly mean “putting gases into the atmosphere” in the first sentence, then the units in the second sentence should be *ppm* or *tons* or something like that measuring amount.
>> On the other hand, if you truly mean units of “W/m^2” in the second sentence, then the first sentence should be about putting *energy* into the atmosphere.
Tim Folkerts says:
I thought we were doing so well, but now we seem to be getting farther apart.

Well what you are telling me is that a non-blackbody with no means of changing its own temperature will have a mean temperature different than that as calculated by the Stefan-Boltzmann laws.
Do you have some evidence of that?

You should consult Trenberth’s energy budget. Evaporation and thermals account for approximately 4 times the net energy warming the atmosphere ~100w/m2 as does surface radiation ~23w/m2
bill, the Earth system global greenhouse effect is measured by calibrated satellite radiometers and near surface thermometers at around 33K so it is certainly not your 10K.
bill, evaporation and thermals account for approximately 0 net energy as measured over climate timeframes when offset by measured condensation and downdrafts during the period.
Bill.
One brief comment. You said “Sounds like you are violating kirchhoffs law of emissivity.”
It might sound like that to some people, but I am not.
The ability to absorb and emit are indeed related, as Kirchhoff described in his law. But this is wavelength dependent.
If a surface absorbs well at 15 um, then it must also emit well at 15 um. But it could simultaneously absorb and emit poorly at 0.6 um. Snow is a perfect example. It absorbs excellently for thermal IR wavelengths, but absorbs poorly for visible light.
You could have a pair of surfaces with similar emissivity but different visible colors. Like black and white enamel paint. The black surface will be warmer. You can have two surfaces with similar color but different emissivity’s. Like two different types of black paint. Or white salt and white sand. The higher emissivity surface will be cooler.
OK so you are arguing then for a natural greenhouse effect that doesn’t need an atmosphere or greenhouse gases?
Ball4 says:
bill, evaporation and thermals account for approximately 0 net energy as measured over climate timeframes when offset by measured condensation and downdrafts during the period.
——————————-
Where do you get that from? Kevin Trenberth allows approximately a net 100 watts of surface cooling to evaporation and thermals.
That results in the atmosphere radiating 199 watts/m2 sourced as 23w/m2 surface radiation, 78w/m2 atmosphere absorp-tion of sunlight, and 98w/m2 surface evaporation and thermals.
bill, you are somewhat out of date using numbers from TFK09. Your +23 net includes returning energy to surface control volume from downdrafts and condensation otherwise the energy dumped into the atm. from updrafts and evaporation (+97) would forever accumulate in the atm.
TFK09 cartoon doesn’t break these downward cycling (-97) thermodynamic internal energy components (-17-80) out of the DWIR shown summed as -333 down from atm. For a report that does a better cartoon job, see Stephens et.al. 2012 energy balance figure that explains & shows explictly those downward components of the water cycle.
I used Trenberth/Kiehl as it leans the hardest toward favoring radiation. (unlike you guys I don’t routinely cherry pick the science in favor of my proposition, though in a formal analysis I will consider it all)
TK is about 4 to 1 in favor of convection. In Stephens the ration jumps up to more than 8 to 1 in favor of convection, primarily by additional thermals and evaporation.
One nice thing about the Stephens diagram is it includes plus and minus watt uncertainty around all the figures. It shows outgoing with an uncertainty of about 5.5watts and incoming to the surface of about 9 watts. Which shows the challenges of choosing an imbalance figure of less than a watt.
“OK so you are arguing then for a natural greenhouse effect that doesn’t need an atmosphere or greenhouse gases?”
Recently, I was simply getting you up to speed on the basic physics of thermal radiation and Kirchhoff’s Laws. And also figuring out what you mean by “the greenhouse effect” — which is NOT in line with the common understanding of “greenhouse effect”. Those are prereqs before any further discussion.
I get that Tim. I was commenting on if a surface absorbs 341w/m2 it must emit 341watts/m2 and that emissivity equals absorbitivity.
So your claim is a planet without an atmosphere with an emissivity of .5 with 341w/m2 absorbed would have a 53k greenhouse effect without any greenhouse gases at all.
“I get that Tim. I was commenting on if a surface absorbs 341w/m2 it must emit 341watts/m2 …”
… or warm up (if it emits less than 341) or cool down (if it emits more than 341. But yes, as a long-term average, it will emit very close to 341.
“… and that emissivity equals absorbitivity.”
Well, yes, the IR emissivity must equal the IR absorbitivity. And the visible emissivity must equal the visible absorbitivity. That does not mean the IR emissivity must equal the visible absorbitivity. I may be mistaken, but you seem think those must be equal and that 341 W/m^2 of incoming sunlight uniquely determines that a planet must be 278.5 K.
“So your claim is a planet without an atmosphere with an emissivity of .5 with 341w/m2 absorbed would have a 53k greenhouse effect without any greenhouse gases at all.”
No, because that is not how I define the GHE. The GHE is specifically the effect of GHGs in the atmosphere. The blocking of thermal IR that has been emitted by the surface.
I will claim such a planet (e = 0.5) is on the order of 53K warmer than a similar blackbody planet (e = 1). But that is not the “atmospheric GHE”. That is the separate “surface emissivity effect”. There could also be a separate “surface albedo effect” and a separate “atmospheric albedo effect”. And several other possible reasons the average surface temperature is not 255 K.
For a country in which global warming is not happening, the US had an “interesting” year.

bdgwx says:
How do you plan to control for aerosols, solar irradiance, advective processes, albedo, and countless other factors that also modulate the temperature?
Aerosols are random, and largely localized. Solar irradiance is constant at any given time, but given the fewer clouds over deserts, that issue is reduced. Albedo is rather constant for deserts. Not sure of any advective processes that are proven. Countless other factors are just that, countless. Therefore given the available options, do you have any better solutions for isolating the impact of CO2 on temperature? NASA literally uses NYC as their poster child for warming, so clearly my approach is lightyears ahead of NASA. They don’t even seem to consider isolating the impact of CO2 on temperature. They just want to show warming, and then blame it on CO2.
Aerosols can and do envelop large portions of the Earth. They are emitted primarily by volcanoes and humans. Note that 100 MtSO2 was lofted into the atmosphere by Tambora and caused the year without a summer. Relative to their mass aerosols have at least 2 orders of magnitude greater effect on the global temperature than does CO2. Aerosols must be considered.
The Sun goes through solar cycles both short and long. This affects how much solar input is received at TOA. And clouds significantly effect how much solar radiation is absorbed. Solar radiation must be considered.
Advective processes transport heat from one location to another. Huge swings in temperature arise solely because of the physical movement of heat. Advective processes must be considered if analyzing temperatures on local or regional scales.
Albedo changes due to snow/ice cover and land use changes. This effects how much solar radiation is reflected vs absorbed at the surface. Albedo must be considred.
There are many factors in play that make it very difficult to isolate CO2’s effect even on a global scale and over long periods of time. If you haven’t considered these factors then you haven’t isolated CO2’s effect.
And while your selection of desert stations might help control for some of these factors it won’t control for all of them. Nevermind that instead of producing a global mean temperature you’ve now produced a desert mean temperature.
And no, NASA does not use NYC Central Park as a poster child for global warming. They use…well…the global temperature. You find the graph here. https://data.giss.nasa.gov/gistemp/graphs_v4/graph_data/Global_Mean_Estimates_based_on_Land_and_Ocean_Data/graph.png
And the exercises of measuring the global temperature and assigning attribution to the cause of its changes are different. You don’t need to consider CO2 to be able to measure to the global mean temperature. You must measure that quantity first before you can analyze the causes of its changes. All of this is really complicated stuff.
And I hate to break the news to you, but you are lightyears behind NASA and most other experts on this stuff. May I kindly recommend you take a piece of humble pie, drop the arrogant know-it-all attitude, and start by first learning about the body knowledge already available before proclaiming how smart you are.
b,
Who are your “experts”? A name or two might help.
Richard Feynman said “Science is the belief in the ignorance of experts.”
You obviously disagree, but you cannot say why. Your belief is of the religious variety.
A triumph of faith over fact, it seems. You can’t even define your silly GHE!
Time to start ducking and weaving? How about some irrelevant distractions or analogies?
Ball4 says:
CO2isLife: ..controlled for the Urban Heat Island Effect and Water Vapor.
UHI is more than adequately discussed in top post. How will CO2isLife control for atm. water vaporexactly?
By selecting sites specifically shielded from the UHI and Water Vapor, ie Deserts.
Selecting only desert weather stations will not necessarily accomplish that ideal, CO2isLife will have to do some proper hard, calculating work.
It is an enormous leap considering that NASA uses NYC as a way to demonstrate warming due CO2 (implied). Show me anywhere NASA makes a serious effort to control for H2O and the UHI effect? They completely ignore the concept and simple seek to show warming. Just look at the N and S Hemisphere. They have huge differences and it can’t be caused by CO2, yet they just ignore it
Deserts have relatively low precipitation, not necessarily low atm. water vapor. Desert weather stations are dry because they are located in regions of descending air. Owens Valley on the lee side of the Sierras and the Atacama Desert on lee side of the Andes are two examples.
Have a better approach? Anyway, claiming that deserts have normal humidity is a stretch. Compare any desert to a Rain Forest and you will see huge differences in the diurnal volatility of temperatures
As a detail hydrology example, look up recent same day June meteorology reports in Madison, Wisc. and Tucson, Ariz. For the same June day, they show precipitable water above Madison was 1.09 in., 119% of avg., Tucson 0.75 in., 93% of avg. Thus the avg. precipitable water above Tucson and Madison on a June day is about the same even though Tucsons annual precipitation is less than one-third that of Madisons.
That is misleading. The variability of water vapor is extreme in Madison vs Tucson. If Tucson holds 0.75 at a near constant level, that is basically a constant in the model. Madison goes from rain to no rain, etc etc. That is high variability that you don’t find in deserts. Perfect, no, better than what people are doing today? Absolutely.
To show I didnt just cherry pick, look up meteorological records for June in Alouef in Algeria, firmly within the Sahara. Finding June water vapor partial pressures and converting to densities shows concentration of wv in Madison is around 20% less than Alouef. And the air temperature in Alouef is higher. This means radiation from the atm. above Alouef is more than likely higher than Madison. CO2isLife properly controlling for water vapor in June would have to pick Madison as a desert station over Tucson & Alouef.
Once again, in any time series differential equation model, change is that matters. The variability of water vapor is much lower in deserts than areas with frequent rains. Perfect? Nope. Better than the current system? Absolutely. Do you have a better solution? Nope. You are just a critic that supports NASA using NYC as evidence of warming.
Today, there are satellite TPW measurements that you can use instead of doing this old fashioned work; not doing the detail meteorological work means less learning about meteorology for CO2isLife who definitely needs to extend studies in the field.
Simply look at atmospheric water vapor and temperature. Where there is water vapor, there is heat, without water vapor, there isn’t heat. NASA literally has a time series of water vapor and temp and they match almost exactly. I’ll try to find the location. I think it is the RSS site. Once again, do you have anything more to offer than criticisms? Have anything to say about NASA highlighting NYC to show warming
Deserts are not “shielded” from atm. water vapor. Since deserts are regions of relatively low precipitation, a relatively higher amount of water vapor stays in the atm. instead of precipitating. Your whole premise on selecting desert stations is easily defeated by lessons learned in a beginning meteorology course of study; I’ll offer that CO2isLife needs to work on that.
I’ve already offered CO2isLife will have to do some proper hard, calculating work. I’ll add also should conduct a thorough literature search in the field before doing “something” in the field that “makes a serious effort to control for H20”:
Manabe, Wetherald 1967: Introduction & conclusions 2,4,5. (of ESSA Research Labs predecessor to NOAA) and subsequent work

B,
Here is NASA –
“Antarctica is a desert. It does not rain or snow a lot there. When it snows, the snow does not melt and builds up over many years to make large, thick sheets of ice, called ice sheets.”
So why does extra water vapour stay in the atmosphere? Too hot, do you think?
Ho, ho, ho!
Give us all the benefit of your vast meteorological knowledge – why is there less precipitation ove4 deserts? Be sure to include tropical, sub-tropical, hot and frigid deserts. I’m joking, of course. You really have no clue, do you?
CO2isLife said: It is an enormous leap considering that NASA uses NYC as a way to demonstrate warming due CO2 (implied)
No they don’t. It just happens to be the station they selected to use for the hyperlink that takes you to their station temperature plotting tool. Nothing more.
CO2isLife said: Show me anywhere NASA makes a serious effort to control for H2O and the UHI effect?
GISTEMP does not control for WV because WV is not believed to cause a significant bias in the measurement of the global mean temperature. I will say that subboxes that are overweight on stations in agricultural zones could cause a negative bias on the global mean temperature since those subboxes would be subject to the suppressive effect of crops on temperatures, but I don’t think this is a big problem. BTW…this is almost exactly the same concept as the UHI bias just in reverse.
GISTEMP does control for UHI because UHI could cause a bias in the measurement of the global mean temperature. They do this by assigning each GHCN station a brightness index from the world radiance database. The BI value is then used in step #2 of the code to identify urban and rural stations and adjust the urban stations trends to match a composite of at least 3 nearby rural stations. If there are not at least 3 rural station available then the urban station is dropped from consideration. More information can be found here.

CO2isLife said: Just look at the N and S Hemisphere. They have huge differences and it can’t be caused by CO2, yet they just ignore it
That’s right. CO2 is not the primary reason for the difference in trends between the NH and SH.
b,
You wrote –
“CO2 is not the primary reason for the difference in trends between the NH and SH.”
OK, then.
What is the difference, and what is the reason?
If you are such a believer in global averages, why do you care about the NH and the SH?
You really don’t know what you are talking about, do you?

Hmmm, seems GISTEMP is making the same elementary mistake that Berkeley Earth made of equating population levels as a trend in UHI. One would think a good 6th grade student would ask if levels affect trends vs trends in levels affecting trends. . . .knowing of course levels do affect absolute temperature. Intentional oversight? Horse blinder science to fulfill an obligation to a funder?
Population trends rather than levels is what they need to use as a control. That is shown clearly in Roy’s work.
Indeed we know that the big cities are much warmer than the rural areas but being warmer doesn’t mean they are continuing to warm at a faster rate. Trends and levels are not the same thing and only rarely does one control the other. This is why academics are not professionals. They have no accountability and they can offer up crap as an assessment and pay no consequence for it and in fact are rewarded instead.

I have to take a moment and point out that these are the kinds of questions that get our attention. I see a totally different attitude in this post as compared to the others. Instead of just “nuh-uh”ing everything you attempt to provide ideas and insights that help facilitate progress in yours, ours, and everyone else’s pursuit of knowledge. And when you are faced with a criticism of your ideas you politely ask “how can we do it better”. That is what makes science move forward. I very much respect this line of thinking.
I’ll see if I can try to shed some light. Quantifying water vapor’s effect (or any agent that modulates the temperature for that matter) is incredibly difficult. Scientists have developed several techniques over the last 120+ years ranging from thermodynamic principals like the Clausisu-Clapeyron relationship, to radiative transfer models pioneered by Gilbert Plass in the mid the 20th century, to energy budget models, to the insanely complex global circulation models and their various parameterization schemes. This stuff is so complicated that no one person can possibly be an expert in all of it. My advice is to start with the works Ball4 mentioned. It might be good to read literature from Plass and Myhre on how they deal with the WV feedback. The IPCC AR5 WGI Physical Science basis is a wealth of information consolidated into “short” 1500 page report that you can uses as a stepping stone for diving deeper. The Schmidt 2010 paper titled Attribution of the present‐day total greenhouse effect goes into a lot of detail regarding WV as well.
b,
Ah! Back to the old ” this stuff is so complicated . . . “, are you?
What rubbish! You are just as silly implying that experimental verification of your CO2 (or something unspecified) speculation is impossible because of its bizarre complicated nature!
Someone as dim as you seem to be is unlikely to be able to ” . . . shed some light.”!
You can’t even describe the phenomenon (the GHE) which is supposedly the basis for some complicated but completely undescribable hypothesis, which of course you can’t actually put in writing.
Warming needs increased heat. CO2 provides none. You are an alarmist fantasist.
Same old …same old…

Do you agree that this is a sign of dementia?
bdgwx, appreciate your comments. If I posted something in the past that was interpreted as rude or inappropriate, I apologize. I’ve creates a list of desert locations from all the deserts identified on the Wikipedia Global Deserts List. Unfortunately, I haven’t been able to post them on this website or others. The problem is, the data is spotting, inconsistent, clearly has many alterations or needed adjustments, and have different time periods covered.
Many appear to show a wave which is what I’ve found in the past. You don’t get warming, you get volatility. Early in the 1900s it warms, then cools post mid 1930s and then warms post 1970s, and takes an especially big jump post 1980. Most sites do show warming post 1980, but that warming is hard to attribute to CO2.
E,
An echo chamber for your political opinions?
Maybe you could address something relevant to the scientific method (or something similar).
Or maybe not. I understand.

Water Vapor and Temperature. The two charts are indistinguishable from each other.
http://images.remss.com/figures/climate/temperature_and_vapor_trop20_V4.png
How can anyone look at the above chart, understand what a true cause-and-effect relationship looks like. Compare this graphic to a graphic of CO2 and Temperature.
Note how the increase in water vapor is largely contained to the N Hemishpere. Why? The N Hemisphere has “Greened.” The result? The N Hemi has warmed relative to the S Hemi. CO2 is the same in both the N and S Hemisphere, Water Vapor is the differential, Water Vapor caused the warming.

Funny how in another post I mentioned about a sudden increase in temperatures post 1980 that couldn’t be due to CO2. Well guess what? Looks like Water Vapor started to increase around that time. Funny how that works. YOu increase H2O and you get warming. What does NASA due? ignores this evidence from their own website and blames the warming in CO2.
http://images.remss.com/figures/climate/vapor_global60.png
If something is understood, it can be modeled. NASA’s own measurements fall outside the range of Model Estimates TO THE DOWNSIDE, meaning that 100% of the models overestimated temperatures, and the value NASA uses as the temperature is the upper bound of a confidence interval.
Sorry, here is the link:
http://images.remss.com/figures/climate/RSS_Model_TS_compare_trop30v4.png
This is what the graph used to look like until NASA dropped the confidence range. No real science uses the upper bound as the estimated value.

Technocracy: the Road to a “Scientific” Dictatorship. Patrick Wood
https://youtu.be/B9LdAjWNOTc
Eisenhower made a similar prediction in his farewell speech.
I’ve pointed out countless times that for NASA to perpetuate their CO2 drives warming fraud, they had to make Temperatures more linear to match CO2. Otherwise their models will never work. They have to manufacture a linear relationship between CO2 and Temperatures.
In a court of law, that is called establishing a motive. NASA manufactured a lie, but the data doesn’t support the lie, so they need to “adjust” the data to make the model give better results.
You have to establish a means/ability/proximity/opportunity. NASA controls the data and has free reign for “adjusting” the data.
Execution. Once you’ve determined the motive and opportunity, you have to demonstrate that they act upon the motive and execute the fraud. Well, according to Tony Heller’s research, NASA did just that. The “adjustments” almost match CO2 exactly. That kind of evidence would be very very hard for NASA to defend in a court of law, and why Alarmists seek to silence, cancel, deplatform, censor and intimidate those that want to truly understand, study, and reach the truth.

https://realclimatescience.com/wp-content/uploads/2018/11/NOAAUSTemperatureAdjustmentVs_shadow-768×766.jpg
This kind of evidence can never make it into cross-examination in a court of law. It would be like Toto looking behind the curtain.
“they had to make Temperatures more linear to match CO2. Otherwise their models will never work. They have to manufacture a linear relationship between CO2 and Temperatures.”
Why do you post such erroneous stuff? How bout a little self-skepticism before posting..
CO2 growth has not been linear, closer to exponential.
The relationship between them is not linear. It is logarithmic. And that gives ~ a match.
Nate, yes it hasn’t been perfectly linear, but putting linear data into the model over such a short period of time will greatly improve the models. You obviously have never run one of these models. The CO2 data for all intents and purposes is linear over the past 140 years. If I ran a linear regression on it I’m sure I would get a pretty high R^2. The problem is, the temperature data is near random. You can’t model a linear variable with a random variable and get a valid model. It is that simple.
In fact, I just ran the R-Sqr and got 0.860517482 on CO2 over the past 140 years. In other words, a linear regression explains 86% of the variation around the mean. Only 14% of CO2 isn’t explained by a linear regression. In other words, to the model CO2 is linear.
This is that a “tight-fit” looks like and works great in multi-variable linear regressions.
http://images.remss.com/figures/climate/temperature_and_vapor_trop20_V4.png
Now compare that to:
http://www.colderside.com/Colderside/Temp_%26_CO2_files/TempCO2.jpg
You simply don’t have the data and math backing your position.
BTW Nate, the facts are NASA is “adjusting” the data in a manner that will improve their model output, so linear or logarithmic, the adjustments have the result of improving the model’s explanatory power. In the real world, the model is adjusted to match the data, you don’t adjust the data to fit the model. Why gather data if you are simply going to adjust it to the level you want? It is completely anti-science. Why not just start with a starting and ending point, and manufacture the data to get the results you want?
Yes, Nate, you are correct. Between 1880 and 2018 CO2 great at a 0.24% rate, so yes, it isn’t exactly linear, but close.
Nate: CO2 growth has not been linear, closer to exponential.
Yes, it grew at a geometric annual rate of 0.24%. Not logarithmic, but geometric.
“The CO2 data for all intents and purposes is linear over the past 140 years.”
Nonsense. Far from it.
“If I ran a linear regression on it Im sure I would get a pretty high R^2.”
No you wont.
“The problem is, the temperature data is near random. You cant model a linear variable with a random variable and get a valid model. It is that simple.”
Nonsense. Just stop declaring your own made-up facts!
The temperature data is noisy but also has a trend. It can be modeled when all forcings, natural and anthro are included.
R^2 0.86 is not good.
Where are you getting CO2 data back to 1880? Lets see it.
CO2,
AGW theory says the Temp should be proportional to forcing and the forcing is proportional to log(CO2). Here is a test of that:
https://www.woodfortrees.org/plot/esrl-co2/mean:12/log/offset:-2.51/plot/gistemp/mean:12/from:1959/scale:0.12
https://www.woodfortrees.org/plot/esrl-co2/mean:12/log/offset:-2.51/plot/gistemp/mean:12/from:1900/scale:0.12
The CO2 level of ~ 295 ppm in 1900 from ice core data would produce a point at -0.04 in 1900 on this plot.
And you can see that would align well with the temperature data.
Imagine trying to defend this in a court of law. You can use NASA’s own charts to implicate them.

The only way to get the mass public to believe all this nonsense is to keep them ignorant of the facts. Any “science” based upon people not looking into the facts and trusting the “experts” simply isn’t science.
Above, Tim Folkerts wrote –
“All of these related examples help test the hypothesis that more greenhouse gases in the atmosphere lead to warmer conditions than a similar planet with less greenhouse gases.
Nonsense. Untestable by reproducible experiment (by definition). Just more cultist speculation. Not science,
Your hypothesis is just silly. First, you need to describe an observable phenomenon, which has not been satisfactorily explained by current physics thus far. Increased heat leads to warmer conditions in general. No need to look any further.
Bad luck, Tim. Obviously, your cultist beliefs are at odds with the accepted scientific method. Look it up if you don’t believe me.
” the accepted scientific method … Look it up”
Apparently you are one of those thinks there is some pre-ordained, official, linear “6 Step Scientific Method” that you can look up. Something like:
1) Define purpose
2) Construct hypothesis
3) Test the hypothesis and collect data
4) Analyze data
5) Draw conclusion
6) Communicate results
This is a myth. This is a simplification for 6th Grade Science Fairs. It is not a *bad* approach to simple topics. But this is NOT how science actually works.
Real science is more like this: https://www.researchgate.net/figure/Scientific-Inquiry-Process_fig6_273520874
Tim,
You do love to complicate things, don’t you?
I’ll help you to simplify things a bit.
You asked a valid question – why is there increased heat (given that a thermometer indicates this is so)?
Are you really trying to say that you don’t understand the physics involved?
Let me know what sort of temperature measuring device mystifies you, and I will answer your questions.
I suggest you brush up on the concepts of heat, energy, temperature, power, and so on. You may be one of those people who are confused about physical relationships.
As for “Increased heat leads to warmer conditions in general.”
OK
No need to look any further”
You are a pretty poor scientists if you stop at the first step. Scientists keep exploring. Scientists would be curious to know *why* there is increased heat.
You are actually right that “current physics” satisfactorily explains why — because GHGs make it tougher for heat to leave, causing more thermal energy to remain and temperatures to rise. You have the answer right in front of your face, yet you refuse to see it.
Tim,
GHGs make it tougher for the heat to enter, causing less thermal energy to reach the surface. You refuse to see this.
But no matter.
During the night, all the heat from the day is lost to space. Plus a tiny bit of the Earth’s remnant and radiogenic heat.
No need to look any further. No magical GHE. Just heat sources, thermometers, and stuff between them slowing the rate of heating and cooling.
“GHGs make it tougher for the heat to enter, causing less thermal energy to reach the surface. You refuse to see this.”
GHGs do (minimally) impact incoming energy from the sun. I have no problem recognizing this fact.
They have a MUCH LARGER impact on the energy leaving. GHG’s are mostly transparent to sunlight ( ~ 0.4 – 4 um) but absorb significant amounts of terrestrial thermal IR (4 – 40 um). And because they impact outgoing energy more than incoming energy, they have a warming effect. Are you willing to recognize this fact?
“During the night, all the heat from the day is lost to space. “.
No. Some nights MORE energy is lost than was gained the day before. Some nights LESS energy is lost than was gained the day before.
The interesting question is how this averages out over longer time periods. Obviously from winter until summer, there is a net gain in a given area — each day tends to be warmer than the one before. From summer until winter, there is a net loss.
Over longer periods (decades, centuries, millennia), there can be and are imbalances. You might be content with “no need to look any further” than a single day and to consider it balanced, but the rest of us might be interested in heat waves and seasons and El Nino and the Medieval Warm Period and ice ages.
Swenson Says: Your hypothesis is just silly. First, you need to describe an observable phenomenon, which has not been satisfactorily explained by current physics thus far. Increased heat leads to warmer conditions in general. No need to look any further.
Swenson, that is what I’ve tried to do by identifying locations that control the the UHI and Water Vapor. When you identify desert locations, you find there is no warming.
Also, you have a temperature differential between the N and S Hemisphere, and over land and sea. All locations have identical CO2, yet wildly different temperature patterns.
CO2isLife
” When you identify desert locations, you find there is no warming. ”
This is a pure lie. I have shown you the contrary many times, and you have obtained excellent explanations from two commenters.

https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=AR000087007&ds=14&dt=1
It is a series of higher highs, the near data is higher than the early data AND THERE ARE NO OVERLAPS, range bounds are upward sloping, there is a continual uptrend, ie, no sudden spikes that immediately reverse themselves. That is what a real scientist would define as an untrend to use in a cause and effect model.There is clearly an upward variation with time.
2) I’ve posted many Desert stations like this. There is no uptrend. If there is warming it is due to spikes that immideatly reverse, and there is a lot of near term data that overlaps the early data. There is volitility, no uptrend. Current levels are below the level of 1890 and many early times. A horizontal like would find 95% of the data being below the level on 1965.

There is nothing I do that is “nonsense.” I back everything I up with sound scientific practices, concepts, data, and apply the scientific method. If I can find just one desert station with no warming since 1880 there is a problem and I’ve found over 580 now that fit my above definition of not having an uptrend, many of them aren’t even desert locations.
NASA uses this station as their poster child for warming. It is the epitome of stations corrupted by the UHI Effect.

A comparison of the averages of all GHCN V3 stations marked as desertic locations, with all GHCN V3 stations in the Tropic area 20N-20S has clearly shown that the 120 year trend for the Tropic stations was lower (0.08 C / decade) than that for the desert stations (0.10 C).
Not the difference as such is interesting: what matters here is that it proves how meaningless it is to try to correlate local temperatures and the global effect of IR intercepting gases.
And the nonsense becomes even greater when you pick some stations and make local claims concerning a global matter.

But… feel free to continue with your simple toy examples, and send us some more hundreds of your nice GISS station chart links!
They pretty good remind me all these ball-on-a-string, coin, merry-go-round, racehorse and cannonball toys, when compared with the huge work needed to ascertain the lunar spin about the axis passing thru its poles.

Here is an explaination for the post 1980 warming. More solar radiation reaching the oceans, the warmer they get.
https://curryja.files.wordpress.com/2021/02/screen-shot-2021-02-26-at-4.50.01-pm.png
BTW, read my posts above. I’ve pointed out many times that temperatures seem to have increased from 1880 to the 1930s, and then cooled, and then warmed again post 1980. This chart shows that solar irradiance did just that. No need to blame CO2, simply look at what the sun did.
https://curryja.files.wordpress.com/2021/02/screen-shot-2021-02-26-at-4.50.01-pm.png
The chart goes to 2000 only. How about showing what has happened to Solar irradiance in the last 20 years
Galaxie500
… and above all, the graph shows the situation in the Arctic: exactly that corner differing the most from the Globe as a whole, regardless what you consider:
– temperatures at ground, in the troposphere and in the lower stratosphere;
– solar irradiance which is far lower at the poles than than anywhere else.
This fixed idea of ‘CO2 is everywhere, thus its effect must be equally measurable everywhere’ is horrifyingly trivial.

Bindidion Says: This is a pure lie. I have shown you the contrary many times, and you have obtained excellent explanations from two commenters.
Bindy, no matter how many times you claim I lie or provide nonsensical rebuttals to my position, I present my arguments in a manner to be used in a cross examination in a court of law. You can claim as many times as you want that my analysis is inaccurate, but a Jury and Judge that aren’t kool-aid drinkers would have real problems with what I’ve posted.
1) Here is JUST ONE of the many many stations that have a long-term record that shows no warming.

https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=AYM00089564&dt=1&ds=14
2) N and S Hemi, Land and Ocean Temps show wildly different temperature charts yet IDENTICAL CO2. You have to explain how a non-differential in CO2 can cause a differential in temperature depending on the location of the station
3) NASA GISS using the upper bound of a confidence level as the estimate is undeniable fraud and would never be defensible in a court of law, no honest person would try to defend that practice
4) I provided a solar graphic that perfectly explains the “wave” type trend I’ve mentioned many times in my posts, You don’t get warming, you get a wave.
5) NASA uses the NYC Data to promote warming, a location known to be corrupted by the UHI effect, warming that is totally refuted by the Southern ExtraTropics data what shows no warming between 1880 and 1970.
https://data.giss.nasa.gov/gistemp/graphs_v4/
You can claim I’m wrong all you want, but I assure you that in cross-examination in a court of law you would loose in embarrassing fashion. There is a reason Climate Alarmists don’t want to debate this issue, and simply rely of the appeal to authority out sourcing of their decision making.

Don’t know your point here, but CO2 is 415 at the surface and 70km up, and I have plenty of surface sites that show no warming. NASA’s own data refutes the claim of warming if you just look at their S Hemi data.
– solar irradiance which is far lower at the poles than than anywhere else.
The GHG effect is thermalization of the outgoing LWIR, the radiance that hits the oceans is what matters. Warm the oceans and you warm the atmosphere. Outgoing LWIR doesn’t warm the oceans.

Your answer:

Sorry: you are INCREDIBLY stubborn.
There CAN’T BE any explanation ‘how the physics of the CO2 molecule is dependent upon the location’; nor did anybody here pretend that.
YOU, and NOBODY ELSE, are here the person writing all the time the ridiculous claim that, if CO2 is uniformly distributed, the temperatures should be the same everywhere, and that if it is not the case, this then would be due to either UHI or water vapor.
How can you have such a trivial terrestrial model in mind?
Some commenters tried – unfortunately without success – to explain you that CO2 IS NOT THE ONE AND ONLY factor contributing to various, complex weather & climate phenomena like temperature, wind, precipitation.

I repeat: your simple-minded, kindergarten-like views about CO2, UHI, H2O etc, remind me all these ball-on-a-string, coin, merry-go-round, racehorse and cannonball toys, when one compares them with the huge work needed to ascertain the lunar spin about the axis passing thru its poles.

Could you PLEASE PLEASE PLEASE STOP writing such redundant, completely scienceless stuff?
J.-P. D.
Binny,
So this from NASA GISS site is obviously too wrong, trivial, and simple-minded, I suppose –
“A study by GISS climate scientists recently published in the journal Science shows that atmospheric CO2 operates as a thermostat to control the temperature of Earth.”
I agree it is not only wrong, but useless as well.
I am glad to see that you now acknowledge that weather phenomena have many contributing factors, and you cannot specify all the factors, or their specific contributions.
At least your views appear to be changing. Good thing. Keep at it.
This comment finally got approved. It shows that the Antarctic Stations show no warming up-trend.

Dr. Spencer, I did this for all the global deserts:
https://en.wikipedia.org/wiki/List_of_deserts_by_area
And what you find is that the vast majority of weather stations located in deserts show no warming. Unfortunatly when I post the entire list with links they seem to need approval from the site. Anyway, that project is deal for a Ph.D. student that wants to truly seek the truth rather than tow the line.
Imagine that, look at what is hitting the headlines today:
NASA mean annual temperature data going back a quarter-century show no warming over Antarctica

“I just ran the R-Sqr and got 0.860517482 ”
Anybody who quotes an r-sqr value to 9 significant digits is obviously well out of their depth.
I suggest you enrol in a course of basic statistics before you go any further.
Studentb: Anybody who quotes an r-sqr value to 9 significant digits is obviously well out of their depth.
That is called copy and paste from an excel spreadsheet. SIgnificant digits? Really?
Do you really think that because a spreadsheet spits out so many numbers that you blindly have to regurgitate them?
Everything after the 0.86 is meaningless.
s,
Actually, everything to do with analysing historical temperatures is pretty well meaningless.
As to significant figures – Edward Lorenz ( Butterfly effect, and all that) discovered the folly of truncation. Given the following measured experimental data -9.284 764 7043 ( no, the last group is perfectly valid), would you like to stick your neck out and claim everything after -9.2 is meaningless?
That would be typical for self styled climate experts.
“NASA mean annual temperature data going back a quarter-century show no warming over Antarctica”
1. No it is not Antarctica – just 7 stations in the small region south of South America.
2. Take Verdansky Station on the penninsula:
https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=AYM00089063&dt=1&ds=14
You can see how cherry picking takes place.
Any trend over the past 25 years is statistically insignificant.
The warming trend over the past 70 to 80 years IS statistically significant.
Again, go back to school to learn about statistics.
Studentb: 1. No it is not Antarctica just 7 stations in the small region south of South America.
Really? That is the data we have to work with. Anyway, just one station with a long-term track record is a problem. How can CO2 be the major temp driver and it doesn’t cause warming in certain locations?
2. Take Verdansky Station on the penninsula:
https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=AYM00089063&dt=1&ds=14
Please explain how CO2, being 415 ppm at all locations, cause warming at one location but not the others? Please explain, I’m all ears.
You can see how cherry picking takes place.
Any trend over the past 25 years is statistically insignificant.
The warming trend over the past 70 to 80 years IS statistically significant.
Cherry picking? Really? I stated a hypothesis in advance and went out to “cherry pick” locations that fit the hypothesis. Haven’t you ever applied the scientific method to answering a question? Obviousluy not, otherwise every scientific experiment “cherry picks” data. That is how you run a “controlled” experiment.
I have no idea what you are talking about as far as statistical significance over 25 years. I’ve posted stations going back to 1880, and even so, CO2 has increased a decent % amount over 25 years so how you can say it should have no statistical significance is beyond me.
Again, go back to school to learn about statistics.
You have e no idea what you are talking about
1. You are not dealing with Antarctica. Dont try and bs
2. “Please explain how CO2, being 415 ppm at all locations, cause warming at one location but not the others?”
You seem to agree that warming is obvious at Verdansky. It is obvious except to blind Freddy.
3. “Peninsula or not, there is no warming,..”
Huh? Make up your mind Freddy.
3. “I have no idea what you are talking about as far as statistical significance over 25 years. ”
Exactly, you do not know what statistical significance is.
Here is a clue – you can have a large trend over a few years but which is statistically insignificant. In which case it is not worth talking about. Or you can have a small trend over many years which is statistically significant – and worth talking about. Please go back to school.
s,
The Earth’s surface has cooled since it was molten, if geologists, geophysicists and other real scientists are to be believed.
No cherry picking there! Who cares about statistical significance when facts are involved?
Self proclaimed climate experts, that’s who!
Gotta love ’em!
Boy! You sure dont know when to quit digging the hole you are in.
Like a stupid dog with a bone.
Just curious Studentb, are you saying this station has experienced warming?
2. Take Verdansky Station on the peninsula:
https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=AYM00089063&dt=1&ds=14
Not sure what you are trying to say here? Peninsula or not, there is no warming, and the alterations in its variability can’t be due to CO2. Just what is your point?
I have been to Verdansky station and can verify that the ice and snow on the Penninsula have been decreasing for decades – (in the same way that Arcric sea ice is decreasing).
Your desperate attempt to deny warming goes against all other evidence.
Professor P Says: I have been to Verdansky station and can verify that the ice and snow on the Penninsula have been decreasing for decades
Your desperate attempt to deny warming goes against all other evidence.
No one denied warming, they deny CO2 is causing it.
1) Antarctica doubles in size each year and then the ice recedes.
2) The ice is melting due to the warm ocean, not the atmospheric CO2
3) NASA data shows Verdansky atmospheric temp to be below 0.00C, how is ice melting in sub-zero temps?
Prof P, your problem is tying the warming alarmism to CO2. If it isn’t due to CO2, warming is Natural, and if it is, what are you going to do? Nothing. We are going to destroy economies and societies to try to stop unstoppable natural cycles and leave us 100% unprepared for the next ice age.
“No one denied warming,..”
Then why show a misleading graph and misleading article claiming this very point?
You seem confused.
“1) Antarctica doubles in size each year and then the ice recedes.”
“2) The ice is melting due to the warm ocean, not the atmospheric CO2
3) NASA data shows Verdansky atmospheric temp to be below 0.00C, how is ice melting in sub-zero temps?”
The ice melts in summer when the temperatures exceed zero. If you look at the graph, it refers to annual mean temperature – not summer temperature.
The ice that is disappearing is terrestrial ice – not sea ice.
“Prof P, your problem is tying the warming alarmism to CO2.”
I said no such thing.
“If it isn’t due to CO2, warming is Natural, and if it is, what are you going to do? Nothing.”
You and I will be buying and driving electric vehicles in 10 years time.
“We are going to destroy economies and societies to try to stop unstoppable natural cycles and leave us 100% unprepared for the next ice age.”
Apart from being alarmist, this is completely wrong. The next ice age is not due for another 10,000 years.
S,
70 to 80 years? Which is it? Is 80 more statistically significant than 70?
Are you significantly appealing to your own authority, or do you just hope everybody is so much in awe of your self importance that they will accept any nonsense you throw their way?
Who cares what you think. You are probably silly enough to believe some of the contradictory whoppers issued by NASA GISS, and NASA climate experts. Tell me you don’t!
Look! There goes another cloud for you to chase and yell at.
As stupid as dogs that chase cars.
S,
No answers then?
Why am I not surprised?
NTZ is tricking you. One of the tricks here is that they using the unadjusted data. I’ll repeat you cannot any conclusions about the magnitude of the temperature trend using unadjusted data due to it being contaminated by quality issues, station moves, instrument changes, time of observation changes, etc. They have also cherry-picked a narrow time window.
bdgwx says:
”NTZ is tricking you. One of the tricks here is that they using the unadjusted data. Ill repeat you cannot any conclusions about the magnitude of the temperature trend using unadjusted data due to it being contaminated by quality issues, station moves, instrument changes, time of observation changes, etc.”
Gee bdgwx I am in agreement with you so much that I would include tricking you into believe it can be fixed as well. . . .especially with inclusion of other unresolved problems like UHI, lack of station standardization (preventing reliable fixing of the problems you have listed)
I have decades of work experience with less than reliable data. IMO, its a good approach to give equal consideration to both the reasoned adjustments and the raw data for at a minimum an understanding of the perceived ranges of uncertainty.
For example what is the difference between a station move and another station being used to adjustment it that’s already in a different location. The choice of this non-comparable station due to being effectively moved is subject to the same sorts of biases including UHI. Of course the ‘BEST’ science available in the view of some folks is UHI doesn’t matter so what does that cause the adjuster to conclude?
Then of course there was the dramatic thinning of temperature stations which problem did nothing but ensure more stations were susceptible to UHI. Use them to adjust the data, then after thats done then adjust the rest of the stations with newly adjusted stations and enlarge the network again.
No accusations just wonder who really is in charge.
Same deal with changing the portion of the globe covered using climate models to estimate historic polar temperatures. Golly haven’t so many scientists proclaimed the models as the BEST science available also? what better tool to reconstruct the missing inadequate data in the polar regions!
A Laurel and Hardy move the piano episode comes to mind. Or maybe the Keystone Cops!
And all that concern is heightened when you find that the sum total of adjustments over time has very significantly slanted the trend in favor of the politically accepted BEST science available.
Some times you just can’t make a silk purse out of a sow’s ear bdgwx. But you certainly can ruin the sow’s ear in trying.
bdgwx says: NTZ is tricking you. One of the tricks here is that they using the unadjusted data.
I’ve posted plenty that show no warming with the adjusted and/or unadjusted. The fact that you have to rely upon “adjustments” on historical data presents its own problem, but even so, there are plenty that are “adjusted” to show no warming.
Here is just one:
Arica (18.35S, 70.333W) ID:CI000085406
https://data.giss.nasa.gov/cgi-bin/gistemp/stdata_show_v4.cgi?id=CI000085406&ds=14&dt=1
Always this straw man about raw v adjusted data.
You might like to read this post at Judith Currie’s Climate etc.
https://judithcurry.com/2015/02/09/berkeley-earth-raw-versus-adjusted-temperature-data/
I quote the last sentence.
“Globally however, the effect of adjustments is minor. Its minor because on average the biases that require adjustments mostly cancel each other out. “
Thats just obfuscation. Berkeley Earth’s homogenization as are most of the homogenizing is all minor. Berkeley earth did not start with raw data. They started with adjusted station data and then applied minor adjustments for some crazy reason that all cancel each other out. I guess it was so they could bullshitt people about adjustments unless you know of a different reason.
EM you have to carefully watch the pea and it get moved from shell to shell and sycophants claim adjustments have not affects.
ProfP Says:
The ice melts in summer when the temperatures exceed zero. If you look at the graph, it refers to annual mean temperature not summer temperature.
The ice that is disappearing is terrestrial ice not sea ice.
I’m sorry, does CO2 surge in the summer to cause the warming, or is it due to the orbit and tilt of the earth? CO2 isn’t causing that warming, and NASA’s data is showing that on an annual basis temperatures aren’t warming. Unless you can explain how an annual measurement can remain flat, and the summers are getting warmer you have a problem. Why is that a problem? Because you have to have warmer summers and colder winters to get a stable annual temperature and that can’t be due to CO2. Yes I know of the annual fluctuations in CO2, but ANtarctica has winters when the annual CO2 is peaking if I’m not mistaken
Prof P, your problem is tying the warming alarmism to CO2.
I said no such thing.
Then you agree that CO2 isn’t causing the warming? You want to drive an electric car because it will have no impact on the climate? Help me understand you position?
If it isn’t due to CO2, warming is Natural, and if it is, what are you going to do? Nothing.
You and I will be buying and driving electric vehicles in 10 years time.
I won’t be driving an EV, the mining of rare earth materials is killing too many children in the Congo and elsewhere. Basic economics dictates that rare earth materials prices will sore with more EV adoption, and gas prices will collapse, making gas powered cars far more economical, and you don’t have to rape the earth and kill children to produce oil.
We are going to destroy economies and societies to try to stop unstoppable natural cycles and leave us 100% unprepared for the next ice age.
Apart from being alarmist, this is completely wrong. The next ice age is not due for another 10,000 years.
According to whom? Al Gore’s icecore chart pretty much proves we’re overdue for an Ice Age. I believe Michale Mann himself claimed that the higher CO2 has prevented us from bing in an ice age right now. What evidence do you have that we are 10,000 years from an ice age? What ice core data supports that conclusion, and be sure to include the standard deviation of the estimated range.
BTW, what causes ice ages? Ice ages start when CO2 peaks, and end when CO2 is at a bottom, the opposite of what would be predicted if CO2 actually caused Catastrophic warming. Anyway, I thought the causes of ice ages was unknown. Maybe you know something the rest of us don’t. Please tell me, what is the mechanism by which ice ages start and end, how it is measured, and please tie it to CO2.
The abundance of evidence suggests that 400+ ppm of CO2 effectively eliminates the possibility of future glacial advances assuming there are no offsetting aerosol releases. See Berger 2015: Interglacials of the last 800,000 years for an introduction to this evidence.
You are forgetting bdgwx that +400ppm is very rare. I realize science believes it can detect one or two instances in history, insert it into some computerized statistical programs and conclude what the likelihood of future events will be.
In this case we might not be warmer than the MWP, and the LIA followed. . . .the entire supposition is premised upon the idea that CO2 is responsible for all the warming we have seen in the last 150 years.
Sort of how it works. Some big powerful pooh butt declares all the warming is due to CO2, the institutions completely funded by Mr. Pooh Butt, immediately endorse it as the best science available and then Berger writes his piece using the best science available. Gee what would it be like if professionals were free to do all that?
Scientists definitely do NOT think CO2 is the sole cause for all of the warming in the last 150 years. A read through the IPCC AR5 WGI makes it plainly obvious that other factors are involved. So I don’t know who the “pooh butt” is that you are referring to, but I do know that he holds a different and wrong position from the mainstream. Perhaps Mr. Pooh Butt should educate himself on the current state of the science. I recommend starting with the IPCC’s Physical Science Basis report which provides an adequate (though not perfect) proxy for the “consensus”.
Obfuscation bdgwx they think is the sole cause of the net warming in that it is assumed that all that natural change has evened out over 17 year or so periods of time. A rather tailored to fit approach of dealing with natural variation.
No. That’s not even remotely correct. Scientists don’t assume anything about natural forcing. Anthroprogenic and natural agents alike are identified and quantified with evidence. Nothing is assumed. And CO2 most definitely is not solely responsible for the warming. The IPCC literature is unequivocal on this matter. Again I advise actually reading the IPCC AR5 WGI Physical Science Basis report. That way you can double check to see if the hypothesis in question is supported by the science before you criticize you it. In other words, this will help protect you from arguing against strawman.
So you are claiming Lindzen is lying when he says: ”How do models with much higher sensitivity manage to replicate the past 50 years? They do so by subtracting from the greenhouse warming essentially unknown aerosols, which they then include as due to human emissions.”
You fail to understand some basic points as evidenced by your claim that, because the annual temperature is less than zero, no ice melting can occur.
You have no understanding of ice ages – which are strongly linked to variations of the Earth’s orbit about the sun, These include periodicities of 20,000…40,000… and 100,000 years.
Look up “Milankovitch”.
Does anyone have evidence that interglacial periods usually last over 20,000 as ProfP claims? That is simply new to me, and I was wondering if it is actually correct?
Yes. Give or take anyway. I will say that this applies to the interglacials during the 100 ka cycle period. There was a transitional period where it switched from 40 to 100 ka cycles in which the interglacial behavior was different. BTW…climate models to a reasonable job of explaining of this transition and the cycles in general over the last 2.5 million years.
https://advances.sciencemag.org/content/5/4/eaav7337
Gee bdgwx didn’t you know you can parameterize a climate model to do anything you want? The claim: ”Here, we present transient simulations of coevolution of climate, ice sheets, and carbon cycle over the past 3 million years. We show that a gradual lowering of atmospheric CO2 and regolith removal are essential to reproduce the evolution of climate variability over the Quaternary. ”
It has some validation. Changes in ice sheets cover 10’s of thousands of years, the ocean adjusts and uptakes carbon and releases carbon. What you are apparently ignorant of is that the ocean contains order of magnitude more carbon than the atmosphere where a halving of carbon in the atmosphere could result in something unmeasurable in the ocean.
Models are parameterized all of the time. It’s not just climate models either. For example, the standard model of particle physics has more than 2 dozen from free parameters. Interestingly scientists have yet to identify a cause for why those parameters are the way they are. Also interesting is the fact that we know for an absolute fact that the standard model is wrong. Yet it is still one of the most useful models in all of science.
Anyway, I’m not too interested in climate models that do not match reality in the same way I’m not too interested in different parametrized variations of the standard model which also do not match reality either. In that context I’m not sure I understand the criticism here. And don’t hear what I’m not saying. I’m not saying the Williet et al model is 100% perfect. Not even close. In fact, if there is anything I’m 100% confident in it is the fact that we’ll never have a model that is 100% perfect in explaining every facet of the glacial cycles. But that doesn’t mean what we do have isn’t useful or that it can be improved upon.
Well particle physics are lab tested so the models are validated to a large extent. You can also do it statistically when your generational cycles are of a manageable length. Unfortunately for climate change science neither is the case.
It is the same for climate models too. The Williet et al. while not perfect provides a reasonable match to the paleoclimate record. It is validated against that record. The same is true of the CMIP suite of models. They are validated against the observations. And although CMIP5 and CMIP6 do not provide a 100% match to observations they do have a reasonably narrow 95% CI on the global mean surface temperature prediction.
BTW…I have not any sans-CO2 or even just weak-CO2 contrarian model that even comes remotely close to the skill the CMIP suite shows. In fact, many of those alternative contrarian models are so bad they cannot even get the direction of the temperature change correct. And some cannot make predictions at all.
bdgwx says:
”And although CMIP5 and CMIP6 do not provide a 100% match to observations they do have a reasonably narrow 95% CI on the global mean surface temperature prediction.”
—————————
Judith Curry calls that 95% CI bunk. So do I. The only way in climate science to get to those levels is don the horse blinders and look at a very narrow range of what could have gone wrong.

Much of it is Texas sharpshooting. Never measure it until the observation records have been corrected. And claiming that we have to know what causes the climate to warm is merely an appeal to omniscience. Perfect stuff for somebody who thinks they know it all.
“lab tested so the models are validated to a large extent. Unfortunately for climate change science neither is the case.”
Parameterization is essential in weather models, which are tested every day, and have been improved over decades. They are extremely successful at predicting the weather.
GCM Climate models are extensions of weather models. Climate models are also tested on past climate.
bill said: Judith Curry calls that 95% CI bunk. So do I.
Great. Now all you and JC need to do is develop your model with 95% CI included and publish your results so that everyone can review it. In other words, instead of just saying it is bunk demonstrate it and have it replicated.
bdgwx says:
”Great. Now all you and JC need to do is develop your model with 95% CI included and publish your results so that everyone can review it. In other words, instead of just saying it is bunk demonstrate it and have it replicated.”
bdgwx we don’t know enough for a true 95% CI. 95% CI is what folks in my profession strive for, to get it you need a lot of knowledge, empirical testing, and a comprehensive examination.
You should read JC’s articles on uncertainty in the field of climate. You can take her articles and with a bit of editing fit those observations to any examination in any industry.
So in essence what you are claiming here is it OK to pull a number out of thin air and thats OK. Some people have too much integrity to do that. And if you don’t have integrity. . . .it doesn’t take a genius to figure out where the goose that lays golden eggs lives.
You seem to take delight in peeling off statistical figures. You still haven’t answered my question of what all that statistical stuff you were going on about in surface temperature records really means in the public debate about how warming is actually occurring. To me the meaning is you really don’t want to discuss the real issues and want to obfuscate with sciencey sounding dialogue that is essentially meaningless to what is actually occurring.
Kind of like claiming Berkeley Earth verified the temperature record when they didn’t even look at the validity of the station data where the lionshare of adjustments occurred. Look I am a professional at determining where to look and what to look at and I can spot that sciencey BS from miles away.
To get (the CI’s indicated for global TOA energy imbalances) a lot of independent knowledge, empirical testing, and a comprehensive examination really is used, bill.
CERES (telescopes looking down) and SORCE (looking up) instruments are repeatable precision instruments and CERES accuracy is calibrated to near surface thermometer measurements out in the wild atm. and ocean.
Being a “professional at determining where to look”, bill ought to do some looking in detail at the pro.s work reporting the CIs of interest.
If that were true Ball4 then energy budgets could get a whole lot closer to the correct answer for incoming and outgoing. But they are not near 1 watt much less a fraction of a watt.
I suppose they probably do it like the models and take multiple inaccurate measures, average them together and claim a high CI.
“I suppose..”
bill, you don’t have to “suppose” how they do it, Loeb et. al. 2018 discusses in detail the CERES calibration efforts to earn the small enough to be meaningful range on incoming (SORCE) & outgoing (CERES) SW and outgoing LW CIs at 95% significance level because as they write, yes:
“the absolute accuracy requirement necessary to quantify Earth’s energy imbalance (EEI) is daunting. The EEI is a small residual of TOA flux terms on the order of 340 W/m^2. EEI ranges between 0.5 and 1 W/m^2…roughly 0.15% of the total incoming and outgoing radiation at the TOA.”
bill said: bdgwx we dont know enough for a true 95% CI. 95% CI is what folks in my profession strive for, to get it you need a lot of knowledge, empirical testing, and a comprehensive examination.
The 95% CI is easy to quantify on your prediction. Just run an ensemble with stochastic perturbations, different parameterizations, monte carlo simulations, etc. Once you have multiple predictions remove the highest 2.5% and the lowest 2.5% and that’s your 95% CI. Your 95% CI can be as wide as needed. Obviously wider 95% CI are less useful than narrower ones. CMIP5’s 95% CI for 2020 is a whopping +/- 0.4C. If JC thinks she can build a model that predict temperatures since 1880 such that 95% of the annual means fall within the 95% CI and do it with better than 0.4C error then she should publish her results so that it can be reviewed and replicated. That would pique people’s interest for sure.
bill said: I suppose they probably do it like the models and take multiple inaccurate measures, average them together and claim a high CI.
Yep. That’s how math works. Google for the standard error of the mean to see just how powerful this technique is.
bill said: If that were true Ball4 then energy budgets could get a whole lot closer to the correct answer for incoming and outgoing. But they are not near 1 watt much less a fraction of a watt.
You can measure the EEI two ways.
1. Measure the ASR and OLR and do the subtraction. Per Wild et al 2013 ASR is about 240 W/m^2 +/- 3 and OLR is 239 W/m^2 +/- 3. The EEI is then 1 W/m^2 +/- 4.2. Obviously the error is too high to draw any conclusions with this approach.
2. Measure the EEI directly. This is done observing the heat uptake in the ocean, air, land, and ice. The net change is the EEI. This method is very accurate. Schuckmann et al. 2020 report +0.87 W/m^2 +/- 0.12.
BTW…because EEI = ASR – OLR you can use tight EEI constraint obtained via method #2 to further constrain the ASR and OLR values. For example…if ASR is 240.00 W/m^2 then OLR must be 239.13 W/m^2. Any experiment now can take the +/- 3 W/m^2 range on the ASR and do a monte carlo simulation (or similar technique) with the tightly constrained matching OLR value.
Let me clarify. Over 30 years of experience has told me very clearly that simply some things cannot be accurately represented via statistics. . . .I am sure to the great shock of a statistician who pretty much sees everything as the head of nail.
Often judgment has to substitute for statistics when samples are not representative, when a great deal of uncertainty exists as to nature of the data being used, etc. So I have devoted several comments to this issue in this post by Roy on that issue pointing out that a lot of the statistic jargon thrown around simply isn’t relevant to the public debate surrounding global warming.
I am not going to attempt to list all the reasons why as it would probably take a week or more but UHI in this thread was at the top of the list.
So no JC is not claiming the CI is wrong. She is saying that it is inappropriate to the conclusion (outright or implied) for quoting CI numbers. The CI numbers may well have importance to the technicians crunch them out but ultimately it merely becomes an obfuscation. An example would be an accountant assigned to audit and account. He may or may not chose statistical tests of those accounts; and the ultimate objective of an accountant is ‘generally’ to achieve the equivalent of 95% confidence. . . .often even higher depending upon risk. If the work lends itself to statistical analysis he will perhaps choose to calculate the CI. Often it doesn’t, particularly in the areas I worked where the problem was a lot of heterogeneity in the tested assets.
All I am saying is there an awful lot of that sort of stuff that precludes statistical analysis in climate. JC recognizes that as well. So my question to bdgwx was what in his view the relevance was to the debate. A question he has chosen to dodge.
The same question can be raised regarding the energy imbalance figure. It is obvious the imbalance is constantly fluctuating radically even over 10’s of thousands of years. We see large multidecadal humps in all the temperature records that go back 100 years and more. Its a complete joke to try to make something out of something that is within the accuracy ranges of history as if that has some meaning in the debate.
Its just sciencey obfuscation. Its elitism where folks want to try to prove how smart they are and that therefore somebody ought to listen to them.
In my experience I was often working in parallel with government auditors. Government auditors work under a huge impediment. Rule of law demands that everybody be treated the same and thus statistical analysis becomes a way to do that even when its not appropriate. Then you have it being done is specific ways that penalizes say the small guy to the benefit of special interests, working especially well when the special interests lie to and confound largely uninterested parties and parties that are not aware of their own interests.
So to swing it back to Roy’s topic. . . .Figure 1 above is intensely interesting. We have some in here like Stokes taking to task the appropriateness of hourly temperature data. Fine that sounds like something to pay more attention to which I think is what Roy is proposing.
But Figure 1 stands out as a finding that runs a spear through most of the to-date UHI attempts I am aware of. It really does need addressing to even begin to understand UHI and how to estimate its presence in the temperature record. Its like a giant red flag. While I find it difficult to get excited about a couple degrees warming, certainly even if a couple degrees is a big deal its of utmost importance to know what it came from.
Give up! You are so way out of your depth. The more you post the stupider you look.
Funny, it actually looks like Antarctica is gaining ice at an alarming/”ballooning” rate.
So Scambos and his Goddard colleague Christopher Shuman wrote a rebuttal to Zwally’s paper. Using NASA and European Space Agency satellites, the 2015 study had measured the changing height of the ice sheet and determined that East Antarctica was ballooning upward by roughly 1.59 centimeters a year (at least from 1992 to 2001 and from 2003 to 2008). Although many agree East Antarctica is rising, Scambos and Shuman think the rate is much lowerand that the discrepancy arose from Zwally’s technique.

Prof P, it looks like you haven’t been keeping up on the research. Maybe you are “Cherry Picking” your location? Or this yet another example of where the NASA data and conclusions are wrong?
Study: Mass gains of Antarctic ice sheet greater than losses
https://climate.nasa.gov/news/2361/study-mass-gains-of-antarctic-ice-sheet-greater-than-losses/
Do you understand the difference between ice accumulation over Antarctica and the warming of the Antarctic Penninsula?
Did you not know that a warming ocean has been predicted to lead to greater snowfall over Antarctica?
Do you understand the difference between terrestrial ice and sea ice?
If this is true, shouldn’t we want to produce CO2?
Interglacials have been typically 1030 ka long. The combination of minimal reduction in northern summer insolation over the next few orbital cycles, owing to low eccentricity, and high atmospheric greenhouse gas concentrations implies that the next glacial inception is many tens of millennia in the future.
https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2015RG000482#:~:text=Interglacials%20have%20been%20typically%2010,of%20millennia%20in%20the%20future.
Personally anyone that thinks CO2 can alter a glacial cycle has never studied the geolocial record. We fell into a glacial period when CO2 was 4000ppm, or 10x the level of today.
The glacial cycles during the Quaternary Period were confined well below 500 ppm with nearly all of them being below 400 ppm and possibly even 300 ppm. The last time CO2 concentration was 4000 ppm was possibly during the early Jurassic Period more than 100 MYA. For higher confidence we have to go back to more than 400 MYA.
Anyway, the paper you cite lays out a pretty good case that CO2 is extremely important in explaining the glacial cycles. In fact they say that “Given the continued anthropogenic CO2 emissions, glacial inception is very unlikely to occur in the next 50 ka” They also say that anything over 300 ppm is enough to eliminate a glaciation within this timeframe. That paper is unequivocal. CO2 can and does alter glacial cycles.
BTW…that was a good paper. That is exactly the kind of thing I’m expecting when I say I want evidence.

I suppose it is rather convincing to you somewhat like a magician’s trick. If you had a job of detecting that you would be more skeptical or you wouldn’t have the job for long.
One cannot support this paper’s article beyond the fact that the Charney Report correctly predicted more warming. But since natural warming cycles can extend 10’s of thousands of years one such prediction doesn’t amount to much scientific evidence being indistinguishable from coincidence.
It is akin to elevating the prognostications of physician and astrologer Nostradamus to best available science.
The trick is a bit more complex than that as natural glacial and interglacial cycles are typically very long with a few exceptions in between, but in no case I am aware of as short as 160 years. Since CO2 has a half life above equilibrium of a few decades at best it is likely that before a glacial cycle can commence there needs to be substantial cooling, causing CO2 equilibrium to drop in advance of the actual glaciation by how many years? So it kind of makes the paper true but the cause of it mostly or completely BS.
As hard as you try bdgwx its all BS. You can’t equate the theory of carbon in the atmosphere to theory of particle physics which has proven itself useful.
You can’t prove CO2 as proven by 160 years of warming, you lack even one generational cycle to do that when you need a good deal more than one to achieve any level of statistical certainty.
IMO, a greater more realistic fear is climate will begin to change naturally toward cooling despite human emissions. We observe it all the time and handwave it away as temporary internal and regional affects. . . .all in a world where evenly distributed CO2 is supposed to prevent that.
“I suppose it is rather convincing to you somewhat like a magicians trick. ”
You equating solid science with a ‘magician’s trick’ says it all. Its your overarching anti-science attitude that bubbles up so often in your posts.
This is a science-based blog. So learn the science and argue with science or don’t post.
Nate says:

LOL! I am not equating solid science with a magicians trick. I am merely equating how you have been taken in by sciencey BS to think the conclusion is based on solid science.
Sciencey BS can be solid science. When it is, it is solid science inappropriately applied to the question at hand.
In the case of claiming from history that a glacial period has never initiated at 400ppm may well be solid science. But is it appropriate science when we know cooling will cause ocean uptake of CO2. Thus the entire premise is a whole lot of unspoken assumptions 1) natural global cooling will not take up more CO2 in the oceans than mankind emits. and 2) that CO2 causes all the warming we have seen and thus will prevent cooling necessary for ocean uptake of CO2.
Neither of those assumptions have been established so its sciencey BS despite the fact its never been seen before.
“Anyway, the paper you cite lays out a pretty good case that CO2 is extremely important in explaining the glacial cycles.”
That is 100% pure nonsense, and evidence that this CO2 obsession has corrupted every piece of “Peer Reviewed” Literature. Glacial Periods start when CO2 is at a Peak, and then end when CO2 is at a bottom. If high CO2 actually triggered the Glacial Periods, we would already be in one, and there would be nothing we could do about it.
Seriously, consider explaining to a Judge under cross examination why 100% of all previous periods didn’t follow this nonsensical CO2 caused cycles, but this time it is different.
Simply answer this question. By what mechanism would CO2 suddenly increase to end an ice age, and by what mechanism would high CO2 suddenly start and ice age, and to add an additional twist, apply a natural resurring cycle? What causes CO2 to cycle to cause the cycle of glacial and interglacial periods? Answer? There is none, CO2 isn’t the cause.
I ask again, what causes the cycle of ice ages? No one seems to know, and certainly no one can tie it to CO2.
The magnitude, timing, and duration of the glacial cycles and causal attribution for each are all addressed in the paper. There is a rather large bibliography that you can use to drill further if you want. I recommend reading through it. It will certainty do a much better job of answering your questions then I ever could.
bdgwx, does it explain how CO2 can end and start an ice age?
The magnitude, timing, and duration of the glacial cycles and causal attribution for each are all addressed in the paper.
How can low CO2 cause warming and how can high CO2 cause cooling?
CO2isLife said: does it explain how CO2 can end and start an ice age?
The start and end of the glacial eras is addressed in the publication.
CO2isLife said: How can low CO2 cause warming and how can high CO2 cause cooling?
The question doesn’t make sense because declining/increasing CO2 causes cooling/warming all other things being equal.

Studentb, please provide any example where I have difficulty with statistics. Just one example. Let’s see who needs the book for dummies.
You have been pinged at least half a dozen times. Dont pretend you havent read the critiques.
Bindidion, Water vapor can swing W/M^2 by 80 to 90 W/M^2 in a single day. You can double CO2 and the impact would be less than a single cloudy day. Over the past 120 years, when CO2 increased from 300 to 420, Backradiation increased by 0.63 W/M2. That is well within the normal variation of a single day, and easily accommodated for with natural processes. Radiation takes milliseconds to leave the system to outer space, so once the system cools to below the previous day, the entire impact of CO2 resets. There is no trapping or accumulation of energy in the system. That is why the graphics showing the recent range of temperatures falling within the range that existed 120 years ago is so important. Without an solid and continue the uptrend, you can’t blame CO2. One El Nino removes years of CO2 additional energy.
CO2isLife
Like me, you are an absolute ignorant of CO2’s effects.
Thus it makes few sense to you to write such a redundant and superficial blah blah, especially when you mention me as its destination.
Read papers, CO2isLife, instead of thinking you know something.
Otherwise, one day you will start to believe those who compare lunar spin with a merry-go-round.
They do, wrt the lunar spin, the same as you do wrt the CO2 context: KISS, i.e. ‘Keep It Simple and Stoopid’.
J.-P. D.
“Like me, you are an absolute ignorant of CO2s effects.”
I am very very familiar with the physics of the CO2 molecule. That is exactly why I am focused on the fact that is can’t cause warming from its current level, and it can’t warm the oceans.
If you isolate the impact of CO2 on temperatures, which I’ve tried to do countless times, you will find additional CO2 doesn’t add enough energy to differentiate itself from normal variations.
Use adjusted or unadjusted, the conclusion is the same.

I appreciate the desire to try and isolate CO2’s effect, but your method is far too simplistic.
From the above linked source:
Twenty years ago, measurements on ice cores showed that the concentration of carbon dioxide in the atmosphere was lower
during ice ages than it is today. As yet, there is no broadly accepted explanation for this difference
I thought this was “Settled Science.”
I repeat my question, how does record low CO2 cause warming and record high CO2 cause cooling?
This “Science” is nothing more than a bunch of speculators masquerading as experts. This isn’t even a hypothesis, it is just working backwards from a CO2 is the cause conclusion. This is truly a joke.
The concentration of carbon dioxide (CO2) in the atmosphere has
varied in step with glacial/interglacial cycles3,4 (Fig. 1). During
interglacial times, such as the Holocene (roughly the past 10,000
years), the atmospheric partial pressure of CO2 (pCO2
) is typically near
280 parts per million by volume (p.p.m.v.). During peak glacial times,
such as the Last Glacial Maximum about 18,000 years ago, atmospheric pCO2 is 180200 p.p.m.v., or roughly 80100 p.p.m.v. lower.
CO2 is a greenhouse gas, and model calculations suggest that its
changes play a signicant role in the energetics of glacial/interglacial
climate change5
. However, we have not yet identied the cause of
these variations in CO2. How do the orbitally driven cycles in solar
radiation set this particular positive feedback into motion?
Here are the facts. I will use 180 ppm as the absolute minimum because that is the level at which plants will die. Increasing CO2 from 180 to 280, the level prior to the Industrial age added a whopping 0.94 W/M^2. Do you honestly think 0.94 W/M^2 can cause the rapid, very rapid warming coming out of an ice age? And if so, why did the rate of change suddenly stop? If 0.94 can cause the extreme warming to emerge from an ice age, why didn’t the additional 0.63 W/M^2 added when CO2 increased from 280 to 415 cause similar warming? Do the laws of Physics change to fit a political narrative?
BTW, from the above quotes from the source provided to me to educate myself, you have provided me with undeniable evidence that this claim that Climate Science is “Settled Science” is one of the biggest lies in history. Thanks for the sources. The quotes you provided me with prove the the “settled science” claim isn’t a myth, it is an outright lie.
What is settled is the fact that CO2 contributes to the Earth energy imbalance and that humans are responsible for the increase in CO2 concentration. This is settled in the same way that other scientific topics like general relativity, quantum mechanics, etc. are settled. “Settled” does not mean that our understanding of every facet of a topic is 100%. It just means that there are certain specific conclusions that can be drawn with high enough confidence that it is essentially impossible for us to be completely wrong about them.
For example, between general relativity and quantum mechanics one of them makes what is often called the worst prediction in all of science regarding the cosmological constant. Yet no one seriously disputes that our understanding of theories is “settled” enough for us to engineer, build, and trust the results of the Global Positioning System, Magnetic Resonance Imaging, etc.

———————
My gawd bdgwx you are sounding more like the Pope every minute.
I’m not sure what you mean here. Can you clarify?
Sure!
Your claim that CO2’s effects on the climate is known as a fact. I don’t dispute that.
Then you promote future warming from CO2 and claim essentially that it would be impossible to be wrong about that.
To better understand my position. I accept a single layer greenhouse model. I actually believe that the atmosphere as a whole operates like a single glazed greenhouse.
Woods proved that the opacity of the glazing of a greenhouse to IR is inconsequential inside of the world’s atmospheric greenhouse.
That says a lot about multiple layered greenhouse theories where you actually introduce an additional layer with very high opacity to IR and get little or nothing out of it compared to a greenhouse with very high transparency to IR.
We know that the atmosphere works like a greenhouse because at TOA you get both a blockage of around 50% 199w vs surface 400w per the known physics of a single layer greenhouse.
You only get a second layer when you again block both convection and radiation in a glass greenhouse at the surface and bingo you get a large boost in mean temperature in the greenhouse.
But Woods showed having an IR block didn’t matter. Why? Well the answer is radiation saturates on the first full absorp-tion.
Radiation contributes nothing to the transfer of energy through opaque solids only conduction applies. In the atmosphere convection makes up the bulk of heat transfer to TOA ~100watts/m2 to maybe 25watts for radiation.
I am aware of the actual theory of continually moving TOA upwards into allegedly cold zones of the atmosphere but this requires much more than what we know about atmosphere physics. Its plausible but declaring it to be impossible it could be wrong is a rather breath taking declaration.
I can go along with Judith Curry’s statement that essentially all we know about additional CO2 in the atmosphere is the sign of the temperature affect.
The greenhouse gas I do see has being potent for climate variation is water vapor. Thats because it actually does change the lapse rate.
Many highly regarded scientists are of the same mind and are still working on natural variation with most looking at cloud physics. Its impossible they could be mostly right bdgwx right?
JC knows more about CO2’s affect on the climate than just the sign of the temperature change. As of 2018 she estimates the 2xCO2 sensitivity at 1.8C…consistent with the IPCC’s 1.5-4.5C estimate.
https://journals.ametsoc.org/view/journals/clim/31/15/jcli-d-17-0667.1.xml
Anyway, the sensitivity is debatable. It definitely isn’t settled. What I’m talking about is the fact that CO2 does have an effect on the climate. And CO2 is being pumped into the atmosphere in large quantities by humans. That is not debatable. It is settled. Even “skeptics” like Spencer, Christy, Lindzen, Curry, Lewis, etc. do not challenge AGW’s core hypothesis and the fact that they settled in the same way other topics of scientific interest are settled.
BTW…JC’s technique on climate sensitivity is such that as the planet continues to warm the sensitivity will continue to increase as well.
“Woods proved that the opacity of the glazing of a greenhouse to IR is inconsequential inside of the worlds atmospheric greenhouse. “
Actually Prof. Wood proved the opposite; the rock salt plate allowing IR negligible opacity to stream out by a lid covering his box showed little temperature difference. When he placed the glass plate with increased IR opacity over the same box, the temperature went up several degrees.

Obviously you didn’t read her caveats. The 1.8 sensitivity she comes up with is based on the rate of observed warming via temperature records and the ‘assumption’ its all due to CO2.
You got sucked into believing here work was some kind of validation of those assumptions probably because you didn’t read it well.

LOL! What is the ‘core’ hypothesis? That its likely increased CO2 probably causes some warming? I can go along with that but one has to be very careful about extrapolating what people say like you did above to the IPCC range of CO2 sensitivity. I don’t think any of those folks are convinced thats correct.
“That says a lot about multiple layered greenhouse theories where you actually introduce an additional layer with very high opacity to IR and get little or nothing out of it compared to a greenhouse with very high transparency to IR.”
“You only get a second layer when you again block both convection and radiation in a glass greenhouse at the surface”
We discussed these models before, Bill, at length. I showed you links to these models. You seemed to have learned that “again block both convection” is not part of the models. Convection is incorporated in them.
Now, you again misrepresent the models. You seem determined to remain ignorant and go back to strawmen.
bill said: Obviously you didnt read her caveats. The 1.8 sensitivity she comes up with is based on the rate of observed warming via temperature records and the assumption its all due to CO2.
I read the whole paper. There is nothing in there that could even be remotely construed as a challenge against CO2’s warming potential. In fact, there is a whole section in which Lewis and Curry defend their method as a means for quantifying CO2’s TCR and ECS. They are literally saying they are certain CO2 has contributed to the warming of the planet and will continue to warm the planet as CO2 concentrations increase. And this is consistent with her are messaging in general based on interviews, blog posts, and other publications. Her whole schtick is not that AGW is wrong in principal, but that the consensus estimate of 2xCO2 sensitivity is just too high.
bill said: What is the core hypothesis?
1. GHGs cause a planetary scale energy imbalance causing Earth to accumulate heat/energy which manifests itself in the warming of land, ocean, air, and melting of ice.
2. Humans are responsible for the bulk of the increase in GHGs including but not limited to CH4, CFCs, O3, CO2, etc. Humans also happen to be responsible for a large amount of aerosols which offset or mask some of the GHG warming.
As I’ve said there is no serious challenge to these hypothesis. They are broadly accepted even by the most vocal “skeptics”. The science is settled in this regard.
What is not settled and where there is plenty of debate is exactly how much GHGs and aerosols have contributed to temperature changes, how sensitive the climate system is to being perturbed, and what kind of effects we can expect from the warming.
Nate ease up on the strawmen.

Well you just don’t have the necessary skepticism. She lays it out in the first sentence of the abstract.
”Energy budget estimates of equilibrium climate sensitivity (ECS) and transient climate response (TCR) are derived based on the best estimates and uncertainty ranges for forcing provided in the IPCC Fifth Assessment Report (AR5)”
If you are looking for something to bolster the IPCC 5th assessment report best estimates and uncertainty ranges for forcing. . . .you are looking at the wrong paper here.

I agree there. Science papers are not a place to put opinions and political statements. Curry holds to that but has elsewhere in her uncertainty papers and else where taken issue with the assumptions that all the warming we have seen is due to CO2. If she knew what the correct allocation would be between natural and anthropogenic warming her sensitivity number would be different and she wouldn’t need the caveat in the first sentence of the abstract. Nice work on her part! She thinks like an auditor and discloses the scope of the examination right on top.
I take it you see the paper has adding to the IPCC results on forcing as detailed in their forcing charts. Its not.

Thats bunk! Lindzen and many others take great issue with aerosols masking stuff, we simply don’t understand aersols enough to conclude that as a net effect.
Aerosols are key to the IPCC forcing estimates. Without them they have to rewrite the entire theory.
Drop that one sentence and yeah I think that since GHG are necessary for the greenhouse effect the statement stands up fairly well, though I recognize some level of doubt that humans are number one on the list for increasing CO2, it does seem a reasonable proposition and I really haven’t seen a good paper on it. O3? I am not particularly interested in such a paper though as I am dealing with other more important issues.

Nice statement there. back pedaling from the ‘masking’?
“What is settled is the fact that CO2 contributes to the Earth energy imbalance and that humans are responsible for the increase in CO2 concentration.”
Yep, were are talking a trivial 0.63 W/M^2 over the past 100 years. What isn’t settled is if that can actually produce actual warming given the natural variation of temperature due to water vapor and other factors. Basically, a single cloudy day will wipe out extended periods of CO2’s contribution.
I believe the net is closer to 2.8 W/m^2. Note that the net includes CO2, CH4, CFCs, O3, aerosols, solar, etc. About 2.0 W/m^2 of that has equilibrated leaving about 0.8 W/m^2 for the imbalance. The exact numbers are certainly debatable. That is definitely not settled.
Yep I would say its fairly accurate. but you left out feedback from emerging from the LIA which would entail albedo changes and some ocean adjustment watts.
Oooh and you left out UHI too.
my how quickly we want to forget the topic of this thread.
bill,
No. The 0.63 W/m^2 figure is not accurate. See IPPC AR5 WGI chapter 8. To be fair, my 2.8 W/m^2 wasn’t right either though. It is actually estimated at 2.1 W/m^2 as of 2011 and we’ve probably added another 0.2 W/m^2 (at least) so it is probably closer to 2.3 W/m^2 give or take as of 2020. My apologies for providing the wrong value above.
bdgwx. The .8w/m2 is model derived. Observations are too imprecise to get there by an order of magnitude.
The EEI is not model derived. I mean it can be and is, but the +0.87 W/m^2 +/- 0.12 from Schuckmann et al. 2020 is almost entirely observationally derived. In fact, they report no use of model simulations in deriving this value from what I saw. They do report on model simulation estimates of the various heat reservoirs, but only for comparison purposes.

————————-
bdgwx you should be a bit more discerning that you are. Schuckmann is an activist. First person to start randomly tossing ARGO buoys for one thing.
From the paper’s conclusion:
”Over the period 19712018 average EEI amounts to 0.470.1 W m−2
, but it amounts to 0.87 0.12 W m−2 during 20102018 (Fig. 8).”
LOL! Enough problems with a warm ocean oscillation from 1976 to the present (recently cooling but remains to see if it continues) on the .47. But the .87 is ridiculous beginning with a deep La Nina of 2010-2012 and then the super el Nino of 2014-16 with the affects of that still playing out at least through 2019.
So what you have there is typical junk Schuckmann who went out and twisted the arms of 37 other scientists to sign on it give it an appearance of respectability. Though I doubt that it took much twisting of James Hansen’s arm since he retired from NASA to be a ‘green’ advocate.
It’s not just Schuckmann et al. though. I post that paper because it represents the best and most recent estimate. You are certainly free to cross reference their extensive bibliography and refer to estimates from other authors if you want. Even Dr. Spencer cites +0.8 W/m^2.
ENSO has little if any effect on the total heat uptake. It is a natural cycle that moves around between ocean, land, air, and ice. It does not create or eliminate heat. In that regard it does not matter how you choose the starting and ending points of the analysis since there will be little if any ENSO bias like there would be if you only analyzed the atmosphere.
Yes. The heat uptake is accelerating. That’s why it is 0.47 W/m^2 from 1971-2018 and 0.87 W/m^2 from 2010-2018.
And as always if you disagree with any of this then find another peer reviewed publication that comes to a significantly different conclusion. Remember…skeptics like me do not like “nuh-uh” arguments. We like “here’s something better” arguments with evidence; lots and lots of evidence.
bdgwx says:
Yes. The heat uptake is accelerating. Thats why it is 0.47 W/m^2 from 1971-2018 and 0.87 W/m^2 from 2010-2018.
—————————-
LOL! So now 8 years is climate? Come on bdgwx you are way too easy to con.
Do you think maybe ENSO accelerated it a bit?
bill said: LOL! So now 8 years is climate?
No. All it is is statement of fact that the EEI is higher later in the period than earlier in the period. This result is statistically significant. Look at figure 7 in the paper. That means the EEI is increasing. What we should be careful about is drawing conclusions about how the atmosphere will respond to that EEI over such a short period of time because the atmospheric is very noisy in terms of its temperature.
bill said: Do you think maybe ENSO accelerated it a bit?
No. ENSO does not create or destroy energy/heat directly. It just moves it around. The EEI is a measure of all energy/heat stored in all reservoirs. It doesn’t matter if the energy/heat moved from the ocean to the air like would be the case with El Nino because the net effect of that transfer is 0 upon the EEI. Look at figure 6. There is little correlation between ENSO and the total energy/heat accumulated by Earth. I will say that ENSO can and does change cloud patterns which can indirectly affect the EEI. But notice that 1) this effect is relatively small and 2) this effect has a net zero effect over long periods of time since ENSO itself is net zero over long periods of time.
bdgwx that is one major back pedal there dude!
You challenged CO2isLife comment of .63W/M2 over 100 years with .8 supported by an 8 year ENSO cycle?
Why do we have to go around in circles with you?
bill,
I’m not back peddling. I think you are conflating ERF (effective radiative forcing) with EEI (Earth energy imbalance). They are NOT the same thing. ERF is the total cumulative radiative force applied to the climate system over a period of time. EEI is the amount of ERF that has not equilibrated yet.
For example, if ERF is 2.0 W/m^2 and EEI is 0.5 W/m^2 and the planet warmed by 1.0C then (2.0 – 0.5) = 1.5 W/m^2 is the amount that caused a TCR of 1.0C. The climate sensitivity is then 1.0/1.5 = 0.67C per W/m^2. And if that 0.67C per W/m^2 figure remains static (it usually doesn’t) then then 0.5 W/m^2 of EEI will produce an additional 0.5 * 0.67 = 0.33C of warming.
You are just obfuscating bdgwx. Its obvious that I was not confusing what you are claiming I was confused about.
You went off the tracks when you started spouting out activist Schuckmann’s attempt to push short term variation into the climate debate.
bill,
CO2isLife’s 0.67 W/m^2 figure is ERF because he said “over the past 100 years”. I’m point out that the ERF is actually closer to 2.3 W/m^2 with about 0.8 W/m^2 being the EEI. I presented the IPCC AR5 WGI as my reference here.
You then said the 0.8 W/m^2 EEI is model derived. It is not. I presented Schuckmann et al. 2020 as my reference here.
I understand what you’re saying regarding Schuckmann’s use of 2010-2018 as the averaging period to compute EEI. But you have to understand that the EEI is an instantaneous concept. What we want to know is what is the EEI today. If we use a long averaging period we’ll get a lower statistical error on the estimate at the expense of raising the systematic error. Likewise if we use a short averaging period we’ll get a lower systematic error on the estimate at the expense of raising the statistical error. In a regime where the EEI is increasing, which is what is occurring, the longer averaging period will bias your estimate too low. The idea is to balance the two approaches. Figure 7 summarizes this quite well.
And the reason why we want a good estimate of EEI is because it can be used to estimate future warming given the observed climate sensitivity. If our EEI estimate has a lot of statistical error then our projection of future warming will have a lot of statistical error. But even worse if our EEI estimate has a large low bias our projection of future warming will have a large low bias.
CO2isLife said: Increasing CO2 from 180 to 280, the level prior to the Industrial age added a whopping 0.94 W/M^2.
5.35 * ln(280/180) = 2.36 W/m^2
CO2isLife said: the additional 0.63 W/M^2 added when CO2 increased from 280 to 415
5.35 * ln(415/280) = 2.11 W/m^2
CO2isLife said: Do the laws of Physics change to fit a political narrative?
Nope. The laws of physics are the same for everyone.
Also I’m curious…what your estimates for the radiative forcing of the forcing agents that were in play during the transitions from glacial to interglacial and vice versa?
bdgwx, you are arguing with MODTRAN, not me. Set it to looking up from the surface, tropical atmosphere.
http://climatemodels.uchicago.edu/modtran/
I’ll even give you your 2.36 W/M^2, simply compare that to the 80+ W/M^2 for a single cloudy or rainy day.
Why use my number and approach? Because glaciers aren’t up In the stratoshere, and the ocean is at the surface, so you need to know how much energy could possibly be converted to thermal energy in the oceans…that is if LWIR between 13 and 18µ warmed the ocean, which it doesn’t.
You’ll have to induce the WV feedback manually with MODTRAN.
“that is if LWIR between 13 and 18 warmed the ocean, which it doesnt. ”
Seawater is effectively opaque to longwave radiation, so it is absorbed by and warms the surface film.
A typical bit of ocean surface absorbs 340W/m^2.
From there it can conduct into the atmosphere, radiate, become latent heat of vaporization or conduct into the bulk water volume.
You assume that the last one does not happen? Why?
“Also Im curiouswhat your estimates for the radiative forcing of the forcing agents that were in play during the transitions from glacial to interglacial and vice versa?”
Those are the numbers I used. Here is MODTRAN. You can check my numbers.
http://climatemodels.uchicago.edu/modtran/
Sorry, I meant to ask…what are your estimates for the other forcing agents that were in play during the transitions between glacial and interglacial eras? Remember, the climate responds to the net effect of all agents; not just one agent.
b,
Climate is the average of weather.
I’ll bet you can’t list all the agents which affect weather, nor quantify their effects.
Trying to appear intelligent won’t hide the fact that you are just another alarmist cultist.
Face reality.
The most viable hypotheses for the cause of glacial/interglacial CO2
change involve the extraction of carbon from the surface ocean by
biological production, either at low or high latitudes, necessarily
allied with changes in the marine calcium carbonate budget. Much
work remains to be done before a consensus can emerge on the
specic driver of glacial/interglacial CO2 changes.</b?
That is pure 100% nonsense. Run a correlation and you will find that CO2 LAGS Temperature by 750 to 1,500 years. Why? Its called Henry's Law. First the sun warms the oceans, then the Oceans degas CO2. Simply put a Coke on a burner and watch what happens. The rate of bubbles will increase as it warms.
The best argument I've seen for the cycle is that the earth travels through the "fingers" of the Galaxy. When in the finger the solar radiance falls and we fall into an ice age. When we leave the finger and more radiation reaches the earth, it warms.

“fingers” of the Galaxy” !! LOL
You are obviously mad – but in an entertaining way.
Its not a bad theory. Bottom line being mad is more closely associated with believing you know thats not it. Similarly those who fervently believe God does not exist are in the same category as people who do believe God exists have a definition of what God means to them. That can be different for every believer thus its really stupid to claim God doesn’t exist. Being skeptical is fine though.
The idea isn’t mad.
If the solar system passed through a molecular cloud, or even a Bok globule it would noticeably reduce solar insolation.
Unfortunately there are problems. Look back along trajectories and there’s no sign of anything we might have passed through.
We do cross the plane of the galaxy every 6o million years, but with no noticeable effect.

Aren’t they called “fingers?” That is what I’ve always thought they were called. Seems others are mad as well.

Strictly speaking they are spiral arms.
Since they orbit at a similar rate to the Sun, we go round together and the Sun does not keep passing through them.

It lead the temperature during the PETM and other ETMx eras and it is leading the temperature today.
CO2isLife said: First the sun warms the oceans, then the Oceans degas CO2.
Yeah. It could happen that way. In fact, that was likely a contributing factor during the interglacial ascents. But that’s not how it is happening today. First, solar output did not increase enough in the early 20th century to explain the warming and its output has been waning since at least 1980. Second, the oceans are net absorbers of CO2 right now.
CO2isLife said: The best argument I’ve seen for the cycle is that the earth travels through the “fingers” of the Galaxy.
Galactic movements take far too long to explain the 40k and 100k year glacial cycles. Nevermind, the the 60 year period since 1960 in which the contemporary warming period became most acute. We can also eliminate the Milankovitch cycles as a cause for the contemporary warming period as well since they operate on 10-500k year time scales.
bdgwx says:

There is a rather tight fit between CO2 and temperature on the 800,000 Vostok Ice Core highlighted by Al Gore. When I ran the Regressions I think the highest R-Square happens with a 700 year Lag.
Going to the 600 million year CO2 and Temperature Chart, clearly there is no relationship between CO2 and Tempearture. CO2 was as high as 7,000 ppm and temp was 22C°, CO2 as 4,000 ppm and we fell into an ice age. No matter what the level of CO2, we never got above 22C° That is pretty much proven by the fact that life existed during all levels of CO2. CO2 never in a 600 million year record when CO2 was almost 20x the level of today caused catastrophic warming. Never.
bdgwx says: It lead the temperature during the PETM and other ETMx eras and it is leading the temperature today.
You don’t know that. Solar output isn’t what is important. The amount of radiation reaching the oceans is what matters. You have absolutely no data sets defining the cloud cover over the oceans. None. Data sets don’t even exist that are required to really explain global climate. It is like a Drug Maker applying for Trillions of Dollars in funding without even the basic data sets to prove efficacy.
bdgwx says: Galactic movements take far too long to explain the 40k and 100k year glacial cycles. Nevermind, the the 60 year period since 1960 in which the contemporary warming period became most acute.
Once again, you don’t know that. We have no data from 800,000 explainings how much solar radiation was actually reaching the oceans. We do however know that something of a cyclical basis is causing tremendous cycles in warming and cooling and we know that one factor isn’t CO2, unless ocean temperatures 700 years in the future can cause higher CO2 today.
CO2isLife said: There is a rather tight fit between CO2 and temperature on the 800,000 Vostok Ice Core highlighted by Al Gore. When I ran the Regressions I think the highest R-Square happens with a 700 year Lag.
Yep. That is consistent with the evidence. That is CO2 lags temperatures in the SH. But in the NH it lead the temperature. And overall globally it actually lead the temperature during the last deglaciation. See Shakun 2012. https://www.nature.com/articles/nature10915
CO2isLife said: Going to the 600 million year CO2 and Temperature Chart, clearly there is no relationship between CO2 and Tempearture.
600 MYA the radiative forcing from the Sun was -12 W/m^2. It would take at least 4000 ppm to produce an offsetting +12 W/m^2 force to cancel out the less luminous Sun. And speaking of the Sun it does not explain the secular temperature trends on million year timescales either. In fact, they often go in different directions. And so we come full circle to what I have been trying to drive home. No one factor can explain everything. You have to consider the net effect of all factors working simultaneously.
CO2isLife said: You don’t know that.
Yes. I do. The PETM was real. It happened. It was caused by a large carbon release.
CO2isLife said: Once again, you don’t know that.
Yes. I do. Scientists can do back trajectories of the solar systems movement through the Milky Way. We know that it takes a really long time for it make significant advances through the galaxy. The time period is far longer than what is needed to explain Earth’s rapid climatic shifts and even the not-so-rapid climate shifts like the glacial cycles. It just doesn’t work. That’s not to say it isn’t plausible factor on ten million or longer timescales though.
bdgwx says: Yep. That is consistent with the evidence. That is CO2 lags temperatures in the SH. But in the NH it lead the temperature. And overall globally it actually lead the temperature during the last deglaciation.
By what possible mechanism could CO2 possibly lead temperatures to end and ice age on a cyclical pattern, and what mechanism would result in CO2 falling before temperatures to end an ice age? Those undeniable observations totally contradict the claim that 1) CO2 controls the climate and 2) CO2 results in warming, otherwise, CO2 peak would trigger an ice age, it would trigger more warming, and record low CO2 would keep temperatures low.
Please, explain how CO2 can start and end ice ages on a cyclical pattern. The stuff you already posted is pure speculation and nonsense.
“Please, explain how CO2 can start and end ice ages on a cyclical pattern. The stuff you already posted is pure speculation and nonsense. ”
It doesnt. The best fit at present is with the 100,000 year cycle of Earth’s orbital eccentricity,
https://en.m.wikipedia.org/wiki/Milankovitch_cycles#:~
That is for the glacial period/interglacial cycle within an Ice Age.
The 300 million years gap between the last Ice Age and the present one is more likely to be because of changes in the position of the continents. These are the only times in recent geological history when there has been land or an enclosed ocean at both poles. If ocean currents can flow freely across at least one pole two permanent polar ice caps cannot form.
Without two polar ice caps you don’t get enough light reflected to drop the global temperature from the normal 19C to the 14C you need to sustain an Ice Age.

CO2isLife,
The argument that because an agent cannot change Earth’s orbit it therefore cannot change Earth’s climate does not logically follow. Or are you arguing that the only way to change Earth’s climate is to change its orbit? Either way the argument is wrong.

Relative to the stars in our local the Sun is moving at 1.8km/second. That is 1 light year every 170,000 years.
The nearest known nebula is the Helix Nebula 700 light years away. At our present velocity it would take 119 million years to reach it.
Ice Ages come along every few hundred million years, the previous one being 300 million years ago.
https://geology.utah.gov/map-pub/survey-notes/glad-you-asked/ice-ages-what-are-they-and-what-causes-them/
On this timescale we would be looking for a nebula which intersected our trajectory about 300 million years ago and 1700 light years away in the direction of Sirius.No suitable candidates.
There’s also the problem of the nebula causing the current Ice Age. Where is it?

What evidence do you have that CO2 causes climate change? Evidence of warming isn’t evidence CO2 is causing that warming. I’ve identified many stations that show no warming trend what so ever. How can many stations are many lat/longs not show warming when CO2 increased by 30% or more? NYC warming is due to buildings, not CO2.

There is extensive evidence from much lab work confirmed by observations of the atmosphere in the wild over long climate appropriate periods. CO2isLife is just way behind in his literature search over the last 160 years. Needs to catch up on homework.
Attribution via extrapolation not observation
All that I wrote is as observed, bill, reasonably matching the physics within 95% confidence bands. Your extrapolation is for speculators not observers.
You mean warming was observed. Its an extrapolation that CO2 causes all of it. Which of course is what you were responding to. Just more sciencey BS
No bill, the actual observations in the 160 years of lab test work and observations/measurements of the atm. in the wild, there are no extrapolations of the test data included. Though there are those that use the past test observational data to speculate using extrapolations of such data.
Ball4,
No lab work has ever shown that CO2 or any other GHG introduces additional energy.
The production of CO2, however, does produce heat.
Maybe you are confusing cause and effect?
Stand close to a roaring blaze. Now try to convince yourself that the CO2 being produced is what is making you hot.
If commenters like Swenson don’t ever look up the relevant reports and understand, only to them then has no lab work ever shown that CO2 or any other GHG introduces additional energy.
LOL! Ball4 the only reason the IR absorbed in the upper atmosphere by CO2 doesn’t warm the upper atmosphere is because it tout suite sends it packing to space.
…and equally tout suite down towards the surface.
But first that IR WAS absorbed and then emitted, just there is relatively less IR to absorb in the upper regions as the opacity of the lower atm. regions increases for an overall upper region cooling effect offsetting the warming effect on the lower regions for no effect on total atm. global median temperature.

“Now a researcher at the University of Geneva (UNIGLE) has proposed in an article to be published soon in Physics Letters B a completely different approach to the problem. One that could apparently resolve this inconsistency. The idea is to accept another constant, Newton’s universal gravitation, which is also part of the equations of general relativity. The idea, which could be a major breakthrough, has been welcomed by the scientific community, although it has yet to be implemented to generate predictions that can later be confirmed or refuted experimentally.
My work writes in his article Lucas Lombriser, sole author of the research – consists of a new mathematical manipulation of the equations of general relativity that finally makes it possible to harmonize the theory and the observation about the cosmological constant.”

“European funds will prioritize decarbonisation”
“Analysts estimate that more than 40,000 million of the EU will go to the development of renewables”
https://en.m.wikipedia.org/wiki/Nir_Shaviv
“He is known for his cosmic ray and solar climate change hypothesis that is not in accordance with the scientific consensus on man-made climate change. In 2002, Shaviv hypothesized that the passages through the spiral arms of the Milky Way appears to have been the cause of the major ice ages over the past billion years. In his later work, co-authored by Jan Veizer, a low upper limit was placed on the climate effect of CO2
His best known contribution to the field of astrophysics was to show that the Eddington luminosity is not a strict limit, [3] that is, astrophysical objects can be brighter than the unexploded Eddington luminosity. This is accomplished by developing a porous atmosphere that allows radiation to escape while exerting little force on the gas. The theory was correctly used to explain the mass loss in the giant Eta Carinae eruption and the evolution of classical nova eruptions. [4]”
“Shaviv has been one of the proponents of a cosmic ray climate link. In 2003 he showed that cosmic ray flux over the past billion years can be reconstructed from the exposure ages of iron meteorites, that these flux variations are expected from the spiral arm passages and correlate with the appearance of ice ages on Earth. [10] In a later work with Jn Veizer, it was shown that the temperature reconstruction over the Phanerozoic correlates with the cosmic ray flux, but does not correlate with the CO 2 reconstruction, thus placing an upper limit on the effects CO 2.. [2] This prompted various reactions from the climate community and rebuttals from Shaviv and his colleagues. [11] It has also shown [12] that the cosmic ray climatic link partly explains the dim sun paradox, as the slowly diminishing solar wind will lead to a cooling effect that compensates for the increased solar irradiance. Furthermore, long-term star-forming activity in the Milky Way correlates with long-term climatic variations. In more recent work with Andreas Prokoph and Jn Veizer, [13] it was argued that the reconstructed temperature has a clear 32 million year oscillation that is consistent with the motion of the solar system perpendicular to the galactic plane. The oscillation also appears to have a secondary modulation consistent with the radial epicyclic motion of the solar system.
Solar variation and climate sensitivityEdit
Because the existence of a significant cosmic ray climate link implies that solar variability will also have a large effect on climate, Shaviv championed the idea that natural climatic variations play an important role in 20th century climate change. Also, if increased solar activity during the 20th century contributed to warming in addition to anthropogenic forcing, then overall climate sensitivity should be less than recommended by standard scenarios that do not include solar forcing. [14]
In 2008, Shaviv used the oceans as a giant calorimeter to quantify solar radiative forcing. He found that the peak-to-peak variations are close to 1 W / m 2, significantly more than can be expected from changes in solar irradiance. [15] In 2011, he published an article with Shlomi Ziskin arguing that solar variability explains about half of the warming of the 20th century, and the other half attributable to anthropogenic forcing.
The Shaviv solar hypothesis has been challenged by Mike Lockwood and Claus Froehlich in an analysis of the sunrise for the past 25 years. They argue that the sun’s activity has been declining since 1985, while global temperatures have continued to rise. [17] Shaviv argues that Lockwood and Froehlich’s analysis is flawed for several reasons. [18] First, while sunspot activity declined after 1985, cosmic ray flux reached a minimum in 1992 and contributed to warming during the 1990s. Second, Shaviv argues that variations a Short-term radiative forcing is buffered by the oceans, leading to a lag between changes in solar output and the effect on global temperatures. While the 2001 peak was weaker than the 1990 peak, the increase in solar activity over previous decades continued to have a warming effect, not unlike the lag between noon and the hottest time of day. The subsequent quantitative model showed that, in fact, there are no discrepancies. [16] The perceived “pause” in the early 2000s is a natural consequence of decreased solar activity.”
From Nir Shaviv’s blog
http://www.sciencebits.com/CO2orSolarHYPERLINK
“Of course, the beautiful correlation between CO 2 reconstructions and temperature on Earth on the multimillennial time scale, as seen in the figure, is often used to demonstrate how CO 2 plays a role in large climatic variations. . This often misleads laymen into believing that CO 2 is the driver of climate, while in fact it could be the opposite, that global temperature affects equilibrium levels of CO 2. In fact, it could be somewhere in the middle, that CO 2 is affected by temperature and that, in turn, causes a greater variation in temperature. However, by itself, this correlation cannot be used to quantify the effect of CO 2 on climate, which can range from no effect to all effects. Therefore, there is evidence that CO 2 is the main cause of the variations over the 20th century. There is no such evidence.
As far as I see it, there are two main reasons why GHGs are blamed as the main cause of global warming, even if there is no actual incriminating evidence: According to the theory, rising GHG levels are expected to increase the global temperature There is no other mechanism to blame for warming. Without any other candidate, the only suspect, i.e. GHGs, must be the cause. These are reasonable statements, except they don’t work for the case of anthropogenic warming. Regarding the first point, we will see below that even the sign of the anthropogenic contribution is unknown, much less its magnitude.
As for the second point, there is another good mechanism to blame, that of indirect solar forcing. This mechanism can do just as good a job in explaining 20th century warming in the form of CO 2, if not a better one.
ANTHROPOGENIC DRIVING – HOW MUCH DOES IT COST? If we want to theoretically assess how much is the human contribution to 20th century warming, we have to address two questions, how much is the human contribution to the changed radiation budget, and how changes in the radiation balance affect global temperature. We start with the anthropogenic contribution. On average, each square meter of the global surface receives a flow of approximately 240 watts per square meter. Of course, equatorial surfaces receive more than polar regions, which is why this figure for radiative flux is an average. The climatic effect of different global processes is generally quantified by their contribution to a net change in average radiative flux. For example, doubling the amount of CO 2 in the atmosphere changes the radiative balance by about 4 W / m (3.8 W / m to be more exact), as if the sun were 4/240 * 100 = 1.7% more sparkly. The scientific report of the Intergovernmental Panel on Climate Change (IPCC) attempts to summarize the effects of all drivers. This is shown in the famous forcing graph below. There are several interesting points to keep in mind. First, there is great uncertainty in an anthropogenic contribution called the indirect aerosol effect. This effect arises from the fact that more small particles in the atmosphere will alter the characteristics of the clouds. This is best seen downstream of smokestacks or in ocean clouds in the form of ship tracks. Since cloud formation, and in particular the characteristics of clouds, are not well understood, the indirect effect of the aerosol is highly uncertain. The second point to take into account is that the solar forcing quoted by the IPCC is 0.3 W / m. This does not include the effect of the sun’s modulated cosmic ray flux, which has ample evidence to back it up, and no real evidence to disprove it. If cosmic ray effects are included, an additional 1 W / m must be added due to increased solar activity (which reduced the flux of cosmic rays reaching Earth, as will be explained below). “

“The ION-CAGE code: a numerical model for the growth of charged and neutral aerosols
Jacob Svensmark, Nir J Shaviv, Martin B Enghoff, Henrik Svensmark
Earth and Space Sciences 7 (9), e2020EA001142, 2020
The presence of small ions influences the growth dynamics of an aerosol size distribution. Specifically, the often neglected mass of small ions influences the growth rate of aerosols, which can be important for the formation of terrestrial clouds. To this end, we developed the Ion and Charged Aerosol Growth Enhancement (ION-CAGE) code, a numerical model to calculate the growth of an aerosol species in the presence of charge, which explicitly includes terms for ion condensation. It is shown that a positive contribution to the growth rate of aerosols is obtained by increasing the ion pair concentration through this ion condensation effect, in agreement with recent experimental findings. The ion condensation effect is then compared to aerosol growth from coagulation of charged aerosols, which is considered independent of ion pair concentration. 25 nm and increases proportionally to ion concentration. The effect of ion condensation is expected to be more important in virgin marine areas. The source code for the model is available through a public repository. “
The debate started by CO2Life seemed very interesting to me and I wanted to contribute information that I had previously sent as links and that it seemed to me that no one had read this way!
I apologize to everyone for the length of the messages! (I will try not to make it happen anymore) and also Thank you very much to those who have read them!!
Happy day to everyone!!
Pity so much of Shaviv’s work has turned out to be mistaken.
Not sure what you mean by Shaviv’s but it seem endemic in the climate business with about 97% of the climate models being wrong also. Indeed its a complete mess!
However there are some bright stars out there. Lewis and Curry are on the mark with observations.
Where do you see that 97% of climate models are wrong? How do you define “wrong” objectively?
If its sufficient error to harm somebody (either physically or economically) who relied on them.
Great. Now we just need a quantification of the physical and economic consequences. Negative values will be “harmful” and positive values will be “helpful”. We will then do a 3-way comparison of these figures.
– the harm/help caused by the 97%
– the harm/help caused by the 3%
– the harm/help caused by not using them
Does this sound fair?
Sure thats easy since we know the benefits are functionally zero.
As to the impacts the examples are already in place. Energy is up about 20% due to California getting on the program.
No way are they going to raise the taxes on the rich when they can make the less fortunate pay.
Full effect isn’t being felt of an additional 20% inflation overall simply because it is only a couple of states. But if it goes federal as we know the price of everything is attached to energy and that will affect food and everything. That alone puts it 4 times over the threshold.
Entropic man,
Why?
Thank you very much Bill Hunter for your comments!
Nobody says anything about Shaviv and it seems the opposite of taking advantage of the weather business, really …
I don’t understand how some climate scientists who question the overwhelming influence of CO2 (in conjunction with other forcers, of course) on the temperature of our planet, are not collaborating closely!
And I put Nir Shaviv in the group along with Svenmark who after the Cloud project at CERN, which had not gone as expected, continues with the Sky project and is now modeling cloud-forming aerosols, with Shaviv Which seem to give good results! And next to them Nicols Scaffetta who is also a modeler …
Out of curiosity and why are Nir Shaviv’s models so bad? And what are its implications for the climate business? … If it can be known!
Many and more sincere thanks to Bill and Entropic for their responses !! And to anyone who wants to make a comment !!
I’m sorry I cut the brave thread of CO2Life !!!
Dr. Spencer thank you very much for this important and super clear publication !!!
I hope that what you propose is carried out happily in the US and outside the US and will undoubtedly serve to moderate the tension in the face of global warming for many people.
But above all:
Hopefully the work you propose arrives in time to promote a more rational exploitation of the countries’ energy resources and the enormous advances in energy production technology that are very close to becoming a reality !: The SPARC project to merge MIT with the CommmonWealth company and only at a cost of $ 200 million, the merger with Q greater than 2 is expected in 2025 !! And there are many more projects in the world of fusion with prospects of achieving this long before the international ITER project. Fusion technology is about to explode and yet the EU is focusing its budget allocation on renewable energies that are inherently dependent on “rare earths” as noted by CO2Life, whose main producer is China (70% of world production ) and also depends on copper, which has limited reserves on our planet … https://www.psfc.mit.edu/sparc

===============================
Solely politics! I work in a policy arena heavily guided by science. The climate arena is one where policy heavily guides science. A functional policy arena associated with science leaves no stone unturned. The one I work in is functionally centuries ahead of where climate science is measured by the challenges of climate science. We have had the benefit of having seen probably a mean of a dozen generations of validation work while climate science continues to struggle with its first generation into which you can easily fit all our generations with room to spare. We still deal with huge uncertainties but our success rates are quite high somewhere above the 80% range and its actually politics that gets in front of the science occasionally that accounts for a portion of lack of success.

Sorry for the slow reply, the site would t let me post for a while.
Shaviv is a good scientist. He puts forward alternative explanations for climate change as testable hypotheses.
Unfortunately none of them have worked out.
The CLOUD experiment at CERN showed that his cosmic ray mechanism is valid but much to weak to measurably affect climate unless a supernova explodes on our doorstep.
On spiral arms and nebula affecting ice ages, Fred Hoyle did the basic physics in 1939 and high dust densities in the interstellar medium would affect sunlight. Unfortunately we haven’t seen such densities for a LONG time. During the last Ice Age 300 million years ago we were 1200 light years in the direction of Sirius and there was no nebula there at the time. Nor is there any neblosity to cause the present Ice Age. IIRC the density of the local interstellar medium is unusually low.
I’ve done some ocean calorimetry myself, using both the thermal expansion and temperature methods. I got a gain of 310^21 Joules/year which agreed with the energy imbalance of 0.7W/m^2 from satellite observation.
What I did not see was an 11 year cycle of faster and slower heat content change due to the solar cycle.
You’re need to do a literature search to confirm the Cosmic ray and neblosity data, but the ocean calorimetry is easy. You can check it yourself.
Entropic man says:
”Unfortunately none of them have worked out.

No it didn’t show it was too weak entropic man. All you toss around here is complete garbage.
”Jasper Kirkby et al. published the results of CLOUD’s first experiment in the journal Nature in 2011,[3] reporting that cosmic rays “seemed to enhance the production of nanometre-sized particles from the gaseous atmosphere by more than a factor of ten.” He added, however, that the particles in question are far too small to serve as cloud condensation nuclei, adding, “At the moment, it actually says nothing about a possible cosmic-ray effect on clouds and climate, but it’s a very important first step.”
You probably should note that a factor of 10 is about 2 orders of magnitude greater than what is needed to explain all global temperature change. Not a bad first step.
But the difference between me and you. . . .I don’t just take a bit of information in my teeth and become a blooming crusader over it all. IMO, the amount of warming we have seen over the past 40 years isn’t at all impressive compared to similar 40 year periods seen in the late 19th and early 20th centuries. We are at least 2 or 3 decades away from any understanding of the affects of CO2. CERN recently discovered that aerosols released by trees may have a global climate impact of reducing cloud cover and warming the planet. Therefore surface station UHI error combined with deforestation represent large uncertainties regarding the source of climate change. You should learn to live well responsibly and limit your mouth vapor to what you actually know.

Pierce 2017: https://doi.org/10.1002/2017JD027475
“Our model suggests that the effect of changes in cosmic ray intensity on CCN is small and unlikely to be comparable to the effect of large variations in natural primary aerosol emissions.”
“Their most recent publication (Gordon et al. 2017) provides their first estimate of the GCR‐CCN connection, and they show that CCN respond too weakly to changes in GCR to yield a significant influence on clouds and climate.”
“in preindustrial aerosol formation. We find that the contribution of ions and vegetation to new particle formation was also greater in the preindustrial period than it is today. However, the effect on particle formation of variations in ion concentration due to changes in the intensity of cosmic rays reaching Earth was small.”
Thanks bdgwx. ‘Models suggest’ ‘estimate’ doesn’t provide any confidence. What we could use is confidence what any scientist says is accountable.
Then we could start having more faith in computer simulations, temperature adjustments, and estimates.
In the meantime, I am sort of sticking with the hard experiments like CERN which the basic AGW theory is completely devoid of as there is no experimental example of a multi-layered greenhouse effect at all.
What I have trouble getting beyond is the only reason the upper atmosphere isn’t 278.5 K is because of the emission of greenhouse gases and so I am told more of them is going to make things warmer. I can see the possibility but it would be a good idea to figure out how to get some evidence of that rather and depending upon an experiment with zero controls which would also support the cosmic theory and many others with each interglacial in the record. So we kind of have come full circle in this argument as you and folks here have maintained the temperature record is the evidence of the CO2 theory. Balderdash!
Even the advocates of CO2 theory acknowledge it could take a long time for feedbacks to play out. That would completely encompass the LIA recovery as easily as the industrial revolution theory. Or even better yet a combination of them which it appears the IPCC becomes more attune with as time goes on. With about a net 8 tenths of a degree warming in the industrial revolution 140 years, 4 tenths is what is considered likely by the IPCC. Hardly something to be concerned about even if it all occurred in the last 70 years. The ice core records suggest natural shifts of up to 2 degree C making the standard for action probably somewhere in the 23rd century.
I would note that CCN is not my favorite theory. My favorite theory evolves down much more complexly than one picking ones favorite theory as the total theory.
Cosmic rays are a player. A player like CO2 perhaps. But neither are the control knob. There are more players. Your studies mention natural aerosol emissions as a comparison.
Deforestation may not have an over the top of the forest fingerprint and it gets dismissed ignorantly like BEST dismisses UHI with a flawed study that begins with the premise that UHI has no effect. He then completely forewent even attempting to derive that UHI trends are a result of population trends and that absolute UHI is a result of population.
An apprentice auditor might make a mistake like that and be forgiven but not twice.
Science advances on the breast of academic freedom. But when academic freedom becomes a swamp it bogs down. Papers like BEST’s UHI paper should be relegated to the trash heap as flawed from the start.
In my view there are more players than aerosols and ghgs. The biggest of them all has hardly been examined, understanding the phase changes of water. Water is the only known atmospheric gas capable of changing the lapse rate and we very poorly understand the physical processes by which it changes phases. Clouds are only the second largest impact on climate. . . .its merely a subset of the big dog.
I will say that CERN found that biogenic compounds have a larger cloud seeding effect than expected.
Seems to be a large number of potential anthropogenic effects in our post industrial climate and/or the measuring of it.
I will put it another way. Climate varies and it seems to vary on rather esoteric changes brought about by a large quantity of variables. Thats somewhat like one of my areas of expertise in the valuation of longterm investments where models simply are only useful for restraining unrealistic assumptions. An approach that has not occurred in climate modeling except for perhaps a small quantity of potential variables and their impacts on a limited number of potential parameters.
We see multi-decadal shifts of climate up to 8 tenths of a degree that appear to related to the ocean. A big problem I see is that 8 tenths of a degree warming in the view of many is about equal to the total amount of climate length warming seen in the industrial age.
Further to promote climate concern a model was developed with CO2 assumed to the control knob for the current warming essentially on every time scale imaginable, including recent warming and up to the entire industrial age.
I am convinced that CO2 indeed does have an impact on true surface temperatures and thus is an important element to our climate. The form by which that occurs must be at least a single layer greenhouse effect. However, accepting that neither describes all the conditions necessary for greenhouse effect nor does it provide an iota of support for a multiple layer greenhouse effect adopted as a necessary assumption to explain the modeled strength of the effect in today’s climate. We know the source of those theoretical models but point out the theory has never been established.
Therefore, it has been hung out there as fact in the tradition of all history on such matters from flat earths to sun’s revolving around the earth. Then the burden of proof is shifted to individuals whom impacts of the mitigation of the affect falls the most hardest upon. They are asked prove otherwise just as it has been for time immemorial and in attempting to do so they meet a storm of resistance, insult, defunding, firings and other means of retaliation.

Curses, that should be 3 10^21 Joules/year.

I believe that being Nir Shaviv a brilliant scientist and so young that he does not stop researching … he will have a lot to say despite the possible mistakes he may have made.

I do not understand how a scientist of the stature of Shaviv has not rectified his conclusions with the sea level … if they are so easily refuted as Entropic man suggests, the truth.

“I do not understand how a scientist of the stature of Shaviv has not rectified his conclusions with the sea level if they are so easily refuted as Entropic man suggests, the truth. ”
He posts regularly on your website. Why not ask him?
Back of the envelope calculation.
Sea level has risen at an average of 3.4 +/-0.4 mm/year since satellites came on line in 1979.Since almost all of it is ice melt and thermal expansion one can approximate that SLR is proportional to the energy imbalance, averaging 0.7W/m^2.
That is almost four solar cycles, enough to spot the effect of solar cycles on sea level rate of rise if there is one.
The maximum of the solar cycle increases solar insolation by 1W relative to the minimum. Convert that to surface variation by multiplying by πr2/4/4πr^2 to correct for a spherical Earth and by 0.7 to account for albedo.
1*0.25*0.7 = 0.18W/m^2
At the solar maximum the sea level rise becomes 3.4 + 0.18/2 =3.49mm/year
At the minimum it becomes 3.4-0.18/2 = 3.31mm/year.
Given the +/- 0.4mm/year uncertainty in the sea level rise, an 11 year oscillation in the rate is unlikely to be detectable above the noise.
Now to Shaviv 2008
http://www.sciencebits.com/solar-debunking-arguments-are-defunct
From somewhere Shaviv’s Figure 1 finds an 11 year oscillation in rate of rise of 10mm/year. This is 50 times too large to be physically feasible.
You are making an error in your analysis. Shaviv is showing a 10mm variation in the rate of sealevel rise and you are comparing that variation to the mean rate.
If you look closely at Figure 1 you will see during solar minimums sealevel is declining and increasing during the maximums. He isn’t saying anything at all about the mean rate.
I have the same finding in temperatures (I did an analysis back around 2012 and found a similar pattern of variation in climate warming.
What is particularly interesting about figure 1 is not only does the variation of sealevel rise match the pattern of the solar constant it varies its amplitude right along with it also.
Its quite likely his analysis is far superior to my temperature analysis due to the fact its likely there are much larger feedbacks in the temperature record as opposed to the sealevel record.
Shaviv’s analysis is also consistent with Syun Akasofu’s 2009 analysis on the shorter time scale it analyzes.
You further your error by assuming the analysis must correlate 1:1 with TSI. What isn’t factored in your analysis is Shaviv isn’t at all contending the cause is entirely encompassed in the thermal effects of TSI so your argument is 100% strawman and to highlight that you use a mean albedo averaged over long periods to argue that albedo has no role.
Its my view and this is consistent with my mean temperature analysis that the variation almost has to be mostly caused by variations in albedo. And that likelihood opens a huge can of worms.
Of most interest to me is whether the albedo effects are caused by variations in climate/jet stream circulation patterns or are a direct result of TSI. The answer would seem to likely be both.
Changes in global air circulation patterns seem very likely having a geographic element to them due to the large variation in mean temperature change between the southern and northern hemispheres and the fact they also have a large variation in geography between the two.
This debate is so far from being over it makes no sense to invent theories of multi-layered greenhouse effects and sell them as the certain answer. There may well be some answer in there somewhere but due to the slowly growing level of CO2 there simply are no generations to work with whereas solar cycles give us a generation every 11 years or so.
Thats why the CO2 multi-layered theory is essentially centuries behind everything else unless somebody makes a big breakthrough.
It is why I think the modeling project generally isn’t worthwhile and why somewhere somebody needs to imagine up a different kind of experiment. But the politicians can’t see the need for it.
At least Pope Urban VIII encouraged Galileo to continue his work, while cautioning him about being to critical of the mainstream scientists still fiddling with the Ptolemy Theory. Obviously Urban VIII was far more open minded than many politicians today.
Dammit. That went wrong.
The sea level rise rates should be:-
3.4*(0.7+0.09/0.7) = 3.84mm/year maximum
3.4*(0.7-0.09/0.7) = 2.96mm/year minimum.
That is 0.46mm/year above or below the mean, just above the 90% confidence limits of +/-0.4.mm and just about detectable.
It is ten times smaller than the variation of 5mm/year above or below the mean which Shaviv 2008 Figure 1 shows. As I said, physically unrealistic.
Thanks Entropic man!
I’ll see him quietly when I can. 🙂 (smile)
Shaviv’s analysis comports very well with the results of my own analysis. Fact is the vast majority of solar energy finds it way into the ocean. The ocean is the answer to the climate riddle.
My analysis which was very simple starts with a smoothing out of the ENSO signal. Such an analysis shows that virtually all the warming occurs during periods of relatively high solar activity with warming reaching near zero during solar minimums. It leaves unanswered why its not negative at solar minimums.
Thus the Syun Akasofu analysis comes into play that there are climate oscillations longer than solar cycles.
Now what are those. It isn’t as clear where we sit on the ocean oscillation chart. Recent warming has been extended beyond the oscillations completed in the 20th century and temperature measures before that are unreliable.
From an ENSO smoothing perspective we are now pretty much at the limit of the 20th century fluctuations.
However, there is a matter of longer termed solar variation. Solar maximums and accumulated feedbacks from extended periods of solar variation.
What is my conclusion? It is that the propaganda loves to focus on short periods, like 30 to 70 years. They argue urgency in the climate crisis to justify those short periods. Yet the entire industrial age could be coincidentally associated with a recovery from the LIA. We know beyond a doubt that climate has been good for us. Food production in warm periods is abundant and difficult in cold periods. Warm periods provide us with leisure time and leisure time allows for a lot of scientific effort when we aren’t all out grubbing all day long for roots.
Youngsters today have no concept of what past generations had to go through.
If you use the 1930’s for a starting point in climate variation you probably capture most of the multi-decadal ocean variation. But you have still left out long term solar changes. Industrial age warming is 8 to 9 tenths of a degree at best using heavily adjusted temperature records and primarily adjusted by those whose allegiance is heavily weighted toward climate alarm. It seems reasonable especially in light of albedo feedbacks from the LIA recovery. It would really be great if we had reliable information that went back a thousand years but such analyses are the subject of constant scientific debate.
There simply isn’t anything alarming going on while governments are throwing the burden of their alarm on those who least can afford it. What we are seeing in energy taxes is the most regressive taxation mankind has seen in the modern era. Apparently by design. . . .keep em cold and hungry and they will vote the way those seeking power wants them to vote.
” virtually all the warming occurs during periods of relatively high solar activity with warming reaching near zero during solar minimums. ”
None of the temperature datasets show the 11 year cycle you describe. Nor does ocean heat content.
The point I made to Adelaide was that the solar cycle does not vary enough to produce a detectable signal in the f temperature and heat content data.
If you have data which shows an 11 year cycle, how’s the time to show it.
Have no way of attaching files. Its my own analysis. but its easy enough to explain in such a way that the hardest part is actually locating the data files and getting them into Excel.
If you plot Had-crut3 since 1940 the first thing you notice are short term fluctuations which have amplitudes up to .65degC rising by up to that much in far less than 2 years.
The overall mean linear warming rate over that 75 years is only approximately .1C/decade. Perhaps that is due to some kind of LIA recovery with albedo dropping as ice melts.
ENSO is the dominant source of global mean temperature variation on short time scales so the 11 year pattern doesn’t present itself to the eye.
So the ENSO needs to be filtered out. I chose to use Excel’s linest function on Had-crut monthly data computing 11 year trends for every month starting with the first 11 years, recomputing it monthly creating an overlapping 11 year series of trends each month to the end of the record.
I then plotted these trends on to a line chart and it makes the same shape figure as seen in Figure 1 of Shaviv. You then can locate the peaks and valleys of the figure and see they line up almost very well and in perfect time with the solar cycles.
The warming cycles peak at around .2c/decade at solar maximums and approach zero (and dropping below zero twice) near the solar minimums.
There is no wonder that the IPCC cannot correlate half of the warming to CO2 because. . . .quite simply. . . . it doesn’t.
Here are the correlations from 1979-2020.
UAH-Sunspot: 0.09
UAH-CO2: 0.47
ERA-Sunspot: 0.12
ERA-CO2: 0.73
Had.CRUT-Sunspot: 0.12
Had.CRUT-CO2: 0.72
OHC-Sunspot: 0.23
OHC-CO2: 0.97
Since OHC accounts for 90% of the heat uptake (Kaufman 2020) it would obviously be the best proxy for the total uptake of heat. As you can see the correlation with CO2 is quite high at 0.97.
If I get a chance I’ll see if I can replicate the analysis using a rolling 11yr linear regression. One important point though…the LR of temperature has units of C/decade as opposed to just C. So a comparison with sunspots (a good proxy for TSI) and LR of temperature tells you nothing about the correlation with temperature, but only the correlation with the rate of change. That’s ok, but its usefulness in isolating causes for the persistent increase in the temperature is limited.
Everything I did was in reference to C/decade. . . .looking for warming trends. I haven’t tried one using sun spots but sun spots are extremely variable even with a distinct pattern. Many periods of time with few sunspots don’t correlate well with the long term average of sunspots potentially spoiling your analysis.
As Roy has shown many of the drivers of climate require several months to be registered as a mean global temperature effect.
My analysis doesn’t show the solar cycle to be the direct cause. . . .only an associated cause. Its the pattern in trends that suggest a significant part of the warming is natural or caused by something other than increasing CO2. However, a signification portion also does fit the trend in CO2.
That significant portion that does fit the long term trend could also be a feedback from a LIA recovery drawing its affect from slowly melting ice sheets. . . .none of that would correlate with sunspots either because it would be correlated with sunspots as a delayed response of perhaps 300 years. You can’t create a smoothing strategy to detect that either.
Thanks Bill and Entropic !!
Your discussion seems is very important because of the implications it has !!!!
I point out that Shaviv’s article is recent, from 2019 …, and as a result of the interview that they were going to do in Forbes and that at the last minute they canceled to do it to a meteorologist who defends the null role of the sun in the current climate change ….
The graphic is from 2008, but in current Shaviv words:
“After that work was published there was not a single paper that tried to refute it. Instead, additional satellite altimetry data covering two more solar cycles just revealed the same. In fact, the sun + El Nio Southern Oscillation can explain almost all the sea level variations minus the long term linear trend (caused by ice caps melting). This is from Howard et al. 2015 (see ref. # 2 at the end): ”
Hopefully Dr. Spencer also revisits this post and the arguments that Shaviv defends !!!
Dr. Spencer himself has acknowledged that he is not invited to any public debate in which he can defend his position.
“the sun + El Nio Southern Oscillation can explain almost all the sea level variations minus the long term linear trend (caused by ice caps melting). ”
I can agree with most of that. There is considerable short term variation and solar cycles,El Nino, weather systems etc will all contribute.

However the long term trend is a bit more complex than just ice melt. As a useful rule of thumb, a 1mm increase in sea level requires the addition of 360 cubic kilometres volume.
First factor is isostatic changes due to rising and falling land. Globally this is causing sea level to drop by 0.3mm/year, increasing the volume of the ocean basins by 108km/year.
https://sealevel.colorado.edu/index.php/presentation/what-glacial-isostatic-adjustment-gia-and-why-do-you-correct-it.
Secondly ice melt. Recently ice melt is contributing 1300 cubic kilometres/year or 3.6mm/year of sea level rise.
(I’ve tried to post links for this, but the site won’t let me. Search for 1.3 trillion tons ice melt)
Third is thermal expansion from whatever is increasing ocean heat content. From my own calculations that is about 720 cubic kilometres/year or 2 mm/year sea level rise.
Add them together and you get a predicted sea level change of
3.0 + 2.0 – 0.3 = 4.7mm/year.
What do you see?
https://sealevel.colorado.edu/data/2020rel1-global-mean-sea-level-seasonal-signals-removed
In the last five years sea level has increased by 23mm. That is 4.6mm/year +/-0.4mm.
I bet your pardon. That should have been 3.6 + 2.0 – 0.3= 5.3 mm/year.
“The magnitude of that spurious component is uncertain due to the black-box nature of the ‘homogenization’ procedure applied to the raw data.”
The “black-box”! If they do not allow their worked to be independently reproduced and checked, then it is not science is it?
I can’t post today and the same happened yesterday!
Does it happen to anyone else?
Entropic man (bdgwx and all of course!),
Have you seen how this physicist reconstructs the sea level change data?
Bill hunter,
I loved your presentation!
I understand that you have also found, as the lead physicist for this publication, a correlation of sea level change with the eleven year solar cycle, which is independent of the stains of our great sphere of fire.
I try to post using synonyms
I didn’t do sealevel but did a correlation of warming in time with solar cycles and it looks like the sealevel graphic. Which makes perfect sense. Warm climate is going to melt ice faster, warm the surface ocean more, thus raise sea level. My analysis showed that perhaps half of recent warming was due to solar variability over the past 80 years.
Co2 is not a GHG.
