Home/BlogThe Version 6.0 global average lower tropospheric temperature (LT) anomaly for May, 2018 was +0.18 deg. C, down a little from the April value of +0.21 deg. C:
Global area-averaged lower tropospheric temperature anomalies (departures from 30-year calendar monthly means, 1981-2010). The 13-month centered average is meant to give an indication of the lower frequency variations in the data; the choice of 13 months is somewhat arbitrary… an odd number of months allows centered plotting on months with no time lag between the two plotted time series. The inclusion of two of the same calendar months on the ends of the 13 month averaging period causes no issues with interpretation because the seasonal temperature cycle has been removed, and so has the distinction between calendar months.
Some regional LT departures from the 30-year (1981-2010) average for the last 17 months are:

After some experimentation, I’ve been able to achieve a lower pressure with my Green Plate Demonstration. As with previous demonstrations, the latest results of this effort can be viewed as a PDF file from my BOX account HERE.
The results of this run at 50 microns gauge pressure are almost identical to that from the last run, which achieved a pressure of 100 microns. After the vacuum pump was switched on, the Blue Plate temperature increased 23.5 C, at which point the Green Plate was raised into position. At the end of the run, the Blue Plate temperature had gained another 10.0 C. The total temperature increase after the pump was switched on was 31.8 C for the previous run and was 33.5 C for the present run. The gain after lifting the Green Plate was nearly identical for both runs.
I think the fact that the results are almost identical to the previous run indicates that convection has now been almost completely suppressed, thus the change in temperature of the Blue Plate must be the result of “back radiation” from the Green Plate.

Gordon and Flynn will be so grateful for having this new insight.
Nice job.
Yet this sentence in your introduction:
All solids and fluids emit infrared radiation as a function of their temperature and the rate of emission is a function of the fourth power of absolute temperature.
is not correct.
The specific T^4 law is only valid for total (integrated) emission of a perfect blackbody.
Yet for any stuff and in particular for gases what’s true in general is that the rate of emission at a frequency f is proportional to the Planck function B ( f, T ) and this is always a steadily increasing function of T. This is all you need since this implies that total integrated emission of any stuff is an increasing function of T, albeit not in general as a T^4 power low .
And, there needs to be an epsilon in front of the SB Law. It’s 1 for a blackbody, but not for other materials. And often a function of frequency.
If epsilon is a function of frequency SB law is in general not valid
Period.
Wrong — emissivity *IS* part of the SB-Law.
And it can be quite a complex function.
IT,
Emissivity can and does vary with wavelength/wavenumber/frequency. Here are just a couple trivial examples:
http://gsp.humboldt.edu/olm_2015/Courses/GSP_216_Online/images/emmisivity-spectrum.jpg
TF
Of course epsilon is in general a function of frequency !
Where did I claim it wasn’t ?
What I claimed and of course still do claim is that if it is SB T^4 power law cannot be really valid, in general.
The reason is very simple: Mathematically it is only the integration of Planck’s function B( f, T ) itself (epsilon =1 or blackbody)) over all frequencies that yields the SB T^4 power law.
https://en.wikipedia.org/wiki/Planck%27s_law#StefanBoltzmann_law
So unless emissivity of a material is essentially a constant independent of frequency over the relevant frequency range, i.e. the material in question is well approximated by a gray body total integrated emission or radiance of that material cannot really verify SB. Merely because B( f, T) * epsilon ( f ) can in general no monger be integrated analytically and yield the simple T^4 temperature dependance.
Gray body is often a good approximation for solids around room temperature but not for gases with specific bands. O2 thermal emission in atmosphere ( Spencer’s satellite T measurements) is essentially in the microwaves and varies simply like T as opposed to T^4.
DA
Wrong
Funny pontification.
Unfortunately you don’t know what you talk about.
TF, DA
Note by the way, that realistic climate model codes of course do by no means use simple SB T^4 power law approximation. This would be much too gross in the case of gases with their drastic frequency dependance of emissivity.
These codes use frequency resolved radiation transfer and resort to Planck’s function again, not its integrated gray body form.
An introduction to frequency resolved radiation transfer and how Planck’s function is used in realistic calculations as opposed to idealized simplified SB law based models of educational purpose intended to demonstrate the essence of the GHE.

Sorry, IT, I misread your comment. Now that I re-read the discussion ore carefully, I agree with everything you say.
First, great job on developing an actual experiment with methodology.
There is an interesting sequence in your testing. You write:
“With the application of a vacuum, the temperature of the Blue plate increased 23.5 C, while the Green plate lagged behind.”
So the presence of an atmosphere (before you turned on the vacuum) kept the temperature of the blue plate lower than without an atmosphere. It appears the presence of a gas, even without convection, around a solid lowers the temperature of the solid.
FTOP, Yes, even though the bell jar is closed, convection loops can develop within and transfer thermal energy from one area to another. The side of the bell jar facing the light receives both visible and IR radiation from the light and thus is warmer than the opposite side. The Blue Plate is also warmed, which would be expected to drive a different loop. That said, the heating is near the top of the jar and some stratification would also be expected, since the bottom is cooler than the top, which would inhibit convection.
By removing most of the air, the formation of convection loops would be suppressed, though I don’t have a way to quantify that effect. At 50 microns pressure, 99.9934% of the SL atmospheric mass has been removed.
I’ll have to finish up an experiment that is rather different in geometry, but shows the same effect. The initial results were just as clear at this bell-jar experiment.
swannie…”I think the fact that the results are almost identical to the previous run indicates that convection has now been almost completely suppressed, thus the change in temperature of the Blue Plate must be the result of “back radiation” from the Green Plate”.
***********
I’ll give you one thing, when you want to see something that isn’t there you see it.
I would suggest you read up on the 2nd law but you seem to be convinced you have disproved it.
Lol, relax guy, neither greenhouse effect nor this experiment as described does not disprove the 2nd law. Now, if the temperature of the blue plate increased above that of *the sun*, e.g. > 6000k, then that would be a violation of slt, but it doesn’t happen.
Gordo, As usual, your comment ignores the facts shown by the demo. You resort to a distraction, since you don’t have the ability to present a serious analysis as an alternative explanation for my findings. I’ve never claimed that my results “disprove” the Second Law, which is about entropy.
E. Swanson says, June 1, 2018 at 9:18 AM:
This statement is tantamount to saying: Look, the temps have gone up and so has CO2. THUS the temperature increase must be the result of the rise in CO2. IOW, I’m correct in postulating that more CO2 in the atmosphere will CAUSE surface temps to increase because, believing this, I predicted temps to rise as the atmospheric content of CO2 went up, and they did …!
What you are effectively saying, Swanson, is that you believe – a priori – that “back radiation” from cool to warm is what causes warm to warm even further, and since you did observe the warm plate to warm even further as you put up the cool plate right next to it, you automatically concluded that your original belief is therefore correct. You simply observed a (predicted) thermal EFFECT and thus immediately assumed YOUR particular theoretical explanation of that effect to be verified.
Sorry, but that’s not how science works. That’s how PSEUDO-science works.
I’m amazed you don’t see this yourself.

Kristian,

He is simply confirming long understood radiative heat transfer physics. Many many experiments have been done, and the theory has been thoroughly tested.
He has excellent reasons to expect ‘a priori’ what indeed he observed.
Can you think of an experiment that will prove him wrong?
No, seriously, I can’t take this “warm to warm” red-herring/misunderstanding/crap any further.
It doesn’t “warm” the warm. It is a measure of how fast warm may cool down. Sunshine is generally what warms the warm.
WERT,
‘It is a measure of how fast warm may cool down.’
What he sees in the experiment are temps reaching steady state with warmer values when the plates are in-line, so I don’t see your point.
If your point is that the green plate is acting to insulate the blue, then fine, but it is doing so via its radiation.
wert, As Nate points out, there’s a constant input of energy flowing into the bell jar “system” via the intense EM from the work light, that energy eventually leaving the bell jar to add to that of the surround room. The temperature at any point within the system represents the state of the internal thermal energy of the body where the thermocouple is located. There are actually four different “systems”, so to speak, as the demonstration progresses, including the initial state before the light is switched on. After equilibrium is achieved for each one, the temperatures have changed to new values reflecting the internal energy states for each component of that system.
In fact it does little difference to have a constant forcing. The back radiation is not what warms the surface, but the Sun.
The back radiation is just a measure of radiative cooling efficiency.
Dear Roy,
I have taken the liberty of posting your blog of June 4th, 2013 “EPIC FAIL: 73 Climate Models vs. Observations for Tropical Tropospheric Temperature” on my blog.
It has incurred a number of questions, (in other places as well as my blog), and I wonder if you could give me some guidance as to the method from which you produced the marvelous graph at http://www.drroyspencer.com/wp-content/uploads/CMIP5-73-models-vs-obs-20N-20S-MT.png
I have followed your references “Courtesy of John Christy, a comparison between 73 CMIP5 models (archived at the KNMI Climate Explorer website) and observations for the tropical bulk tropospheric temperature (aka “MT”) since 1979 (click for large version):” and am working on the KNMI Climate Explorer website and obtained some raw data there.
However I cannot find the data for the “4 radiosonde datasets, and 2 satellite datasets (UAH and RSS)”.
Trust you can find the time to help me here, esp with the latter data set.
Will be much obliged if you can help.
Best regards
Roger
The NOAA CDAS preliminary monthly average global mean surface temperature for May 2018 based on daily CDAS averages was 15.59 C, which is the lowest May average since May 2015 at 15.54 C. The May 2018 global mean surface temperature anomaly referenced to 1981-2010 was 0.23 C compared to 0.36 C for April and was the lowest anomaly since 0.16 C for July 2015.

Good info – thanks for reporting it here.
Being that temps did not gain in this last Month, then I would say that it is all down slope from here. I had been wondering if there was going to be a temp spike due to the heavy rainy winter of 2016/17 on the West Coast of the US. Such winters typically lead to a temp spike around 20 months after the heavy winter, which should have become apparent by now.
The conclusion being that the temp spike which can be seen in past records after a heavy West Coast winter is due only to the rise of the sunspot index after coming off of the minimum. In this case the minimum still has around 2 years to run, and so there is no spike in global temps to be seen. That strongly implies that global temps are now going to steadily cool through this year and the next year,if not for the next 3 years. This is going to get very interesting from this point in time.
Yes, a warming trend over 472 months, followed by 2 months cooler than the previous month, is definitely a sign that it’s all down slope from here. Definitely. {eye roll}
To the best of my knowledge there has not been any warming since 1998, but don’t let your fantasy get in the way.

I guess your knowledge is based on UAH6.0 LT. So let’s go there.
Linear estimate since Jan 1998: 0.07 ± 0.02 °C / decade.
This is not much, I agree! But nevertheless it is over 50 % of the trend since 1979.
Linear estimate since Jan 2008: 0.45 ± 0.05 °C / decade.
Yes, Tim Wells: don’t let your fantasy get in the way.
You are just measuring a transient, El Nino spike in the latter one. Meh.
@ Bart …Note that L.P. is using the low point of 2008, and then drawing a line to current time to get that high rate. Take a look at the UAH graph above and note where !/2008 sits on the graph. I would call that an unripened cherry at best.
Hmm the linear estimate since the end of the last solar minimum has been positive… Hmm cant think of any reason why…. Must be man!!
Tim, that’s wrong. You need to redo your calculation.
Linear trend of UAH LT v6.0 from Jan-1999 to present = +0.14 C/decade, R^2=0.18
We’re all gonna die !
John Garrett
Thanks for your meaningful contribution to the discussion.
Garret is right though, the only thing that matters is the legacy that we leave behind.
@DA …I am running very strong on my forecasts. So let us see what happens between now and September. I say that temps will not rise by any significant amount over the course of this upcoming summer. They may even fall through the summer due to cooling influences around the globe.
Also, note that there has only been a slight warming trend over the last 472 months, approx 0.5C since 1979 with an addition of 74ppm of CO2 added into the atmosphere over those 472 months. Some part of that rise is natural. So at best the influence of CO2 can only be small to tiny.
Care to make a forecast of your own, if you are able? I would think that after all of these years, and all of the time and effort on your part with your obvious superior qualities that this should be easy for you.
0.5 C since 1979 is “slight?” Compared to what?
Some part of that rise is natural.
How much? From what? Be prepared to defend your number, because you know we’ll have hard questions about it.
@DA …no one knows how much is natural versus whatever part is caused by rising CO2. Do you have an opinion based on anything of substance in that regard?
As for what drives the warming, the main warming occurs in the oceans as a first step, and that is solar driven, imo. I defend my claims by making accurate forecasts and predictions.
What natural factors are there?
How much warming/cooling have they caused since, say, 1970?
It’s entirely possible .. actually probable that most of the increase in CO2 has been natural and that nature is doing a great job of using the higher level with a significant increase in plant growth observed over the last 30 years directly due to CO2 fertilization
David, compared to higher temperatures of the past and also to faster 40 year rises in temperature in the last 150 years
@ DA …playing ignorant does not look well on you. I already gave answer to that question of yours.
So you are claiming to be able to see an 11 year cycle in global temperatures?
The impact of the 11 year solar cycle is modulated by other cycles pertaining to the uptake and release of energy from the oceans. In particular, the wobble of the Earth’s axis with a 9.3 year period induces harmonics at about 5 years and 60 years. These are evident in the temperature data.
What are the temperature amplitudes for these claimed 5- and 60-year cycles?
The 60 year is about 0.2 degC.
Quick research reveals that the amplitude of this wobble (nutation) amounts to 17 seconds of arc in longitude and 9.2 seconds of arc in obliquity.
SECONDS. Do you understand how small an angle that is? It is less than half a percent of one degree. Do you really believe that could have even the slightest effect on climate?
B,
If the atmosphere acts chaotically, there is no minimum perturbation which may result in chaotic behaviour ie unpredictability.
The IPCC agrees that prediction of future climate states is impossible, as the atmosphere acts chaotically.
So yes, you are stupid and ignorant. You understand nothing about chaos – even less than the IPCC.
Are you happy now?
Cheers.
Bond: clearly, I meant the amplitude of *temperature*
David
You seem to have difficulty discerning when I am responding to you.
I was clearly responding to Bart.
That actually works out to fairly massive motion at the surface, which is where the oceans get stirred up by it. The Earth is about 6.3 million meters in radius, you know.
‘fairly massive motion at the surface, which is where the oceans get stirred up by it’
I tried stirring my coffee by tilting the cup at a slight angle (10 degrees) and slowly rotating that tilt about once in 5 sec.
Shockingly, it did not stir the coffee at all.
But, I guarantee it did change the rate at which it cooled. Remember, we’re talking changes on the order of tenths of a degree here. And, movement of incredibly massive amounts of water.
Global temperature usually spiking late in or around the end of a wet winter in the US West Coast is usually due to a usual cause of such wet West Coast winters – El Nino. US West Coast winter precipitation does not always correlate well with ENSO, global temperature in the first half of a year correlates better with ENSO in the winter that ends early in the same year than West Coast precipitation does. So when West Coast precipitation is atypical for the ENSO status of a winter, it is likely to be atypical for global temperature (with respect to the trend of global temperature smoothed over the previous several years) late that winter and that spring.
This past winter, there was a mild/minimal La Nina, which typically makes late winter and springtime global temperature below the trend line of multiyear-smoothed global temperature over the previous several years – global temperature obeyed last winter’s mild La Lina. California rainfall did not, because it sometimes doesn’t. The recent great El Nino didn’t bring California that the great El Ninos of 1997-1998 and 1982-1983 did. Another exception was the El Nino of 1976-1977, which did not fix a California drought although it did produce a now- expectable spike in global temperature. There was a problematic weather pattern that sometimes happens, a blocking pattern of upper atmospheric ridge on the West Coast, and upper atmospheric trough in the eastern US until that pattern broke spectacularly in early February 1977. December 1976 and January 1977 were spectacularly cold in the eastern US, after a chilly fall and cool summer, but spring 1976 was warm (and irregularly warm) in the eastern US. The highest temperature in Philadelphia in 1976 was a new record high for the month of April (since broken by 1 degree in 2002).
The recent great El Nino didnt bring California that the great El Ninos of 1997-1998 and 1982-1983 did.
No, but globally the 2015-16 El Nino was about (GMAT average over the season) 0.4 C above that of the 1997-98 El Nino, which itself was about 0.3 C above that of 1982-83.
El Ninos are getting warming.
La Ninas are also getting warmer.
So are neutral warming.
=> global warming
should be “…so are neutral years….”
David, serious question here with no snark.
And I understand that the hard data is limited.
But, could the same (probably) be said about 1700-1850? Certainly, there was global warming during that period.
And, if so, is there a way to then quantify a natural component of global warming.
Jake,
That is a great question, and I would be eager to see David’s response as well, as it is why I have had a hard time buying into the C02 caused global warming movement. Especially, when we know that we already had a medieval warming period that was at least as warm in the northern atlantic region that was at least as warm as we have now and CO2 was not the cause.
In addition, we have a little ice age that had a cold variance at least as dramatic the other direction as what we see now as well and obviously C02 had nothing to do with that either. So, we know that the earth’s climate can swing at least as much as it is now without C02. So, how are we sure that C02 is now the primary cause of this warming that we are seeing?
Finally, you might get a kick out of Al Gore’s C02 Emissions Chart…you can look it up on Youtube under that search term. He is trying to make the point of how dramatically C02 is rising, but he essentially shoots himself in the foot from the graph, because he shows that C02 is much, much higher than it has ever been in the last 650,000 years in earth’s history, yet we have had at least 2 periods in the last 650,000 years that were warmer than we have now (per Gore’s Graph).
So, Gore essentially invalidates his premise that CO2 is a cause of global warming, as C02 is much, much higher than any time in the past 650,000 years, yet earth has had higher temperatures in the past 650,000 years than now…
Jake,
Here is a paper using instrument record of central European temp back to mid 1700s.
https://www.st-andrews.ac.uk/~rjsw/PalaeoPDFs/GlaserRiemann2009.pdf
Fig 4.
Many of the ups and downs correlate to volcanic erruptions.
Jake,
Berkeley Earth estimated the natural variation to be +/- 0.17 C.
It looks like short term deviations can be much larger than that.
ENSO is a natural event not caused by CO2.
If both El Ninos and La Ninas are getting warmer (and I make no comment as to whether that is correct) then it it all but inevitable that neutral years, ie., years between ENSO events will be bound to be warmer. In fact if both El Ninos and La Ninas are warmer, it would be almost impossible for neutral years to be cooler.
Thus what you are suggesting would appear to be simply the outcome of natural events unless you can explain how CO2 drives ENSO.
The fact that ENSO events are independent of the greenhouse effect is the whole point.
ENSO events are not getting stronger or weaker. But the change in temperature they cause is being superimposed onto an ever increasing baseline.
I have maintained for years now which many have not paid attention to ,which is in order to have solar exert a climatic impact that is more significant two conditions must be present.
CONDITION NUMBER 1 – 10+ YEARS OF SUB – SOLAR ACTIVITY IN GENERAL.
Which is now satisfied since sub solar activity in general has been occurring since late 2005. That proceeded by extremely active solar conditions for several decades, the modern maximum.
CONDITION NUMBER 2 – Within the sub -solar activity in general low average value solar parameters must be meant and sustained for a period of time. Those solar parameters having values equal to or lower than the solar values that take place in typical solar minimums within the so called 11 year sunspot cycle, and longer in duration.
It looks like this is now occurring. Year 2018 being the first year where it looks like my 2 conditions for global cooling due to solar activity are taking place. This is why I am confident to say this year is a transitional year in the climate and no further global warming is going to take place starting with this year and moving forward.
Thus far I would say the climatic trends are looking pretty good(this year) with global temperatures now running lower according to satellite data lower then a year ago thru this time, with overall sea surface temperatures cooling not to mention the North Atlantic in particular which is undergoing extensive cooling and is a very important area in the global climate picture. Also with the atmospheric circulation being less zonal.
The other area is what is happening with the geo magnetic field in regards to it’s strength and orientation which when in sync with solar activity will compound given solar effects. In this case they are both weakening.
The upshot of this is overall sea surface temperatures should drop and a slight uptick in albedo is probably going to happen due to an increase in global cloud coverage, snow coverage and an uptick in explosive major volcanic activity. My opinion.
If one looks at the climatic history objectively it is clear that every prolonged solar minimum results in global cooling without exception. THOSE ARE THE FACTS NOT MY OPINION.
Finally people are stuck on the false concept that the climate is going to change slowly and gradually which is false . That only being true when the climate is locked in a specific climate regime which had been the case after we came out of the Little Ice Age to present.
This may now be changing in my opinion.
As I said last month, you claimed last year that 2017 was the transitional year.
it was late year 2017.
No, it was 11 months ago:

@ Bond …Sal has never been able to make a specific forecast/prediction in all of the years of his comments. He takes bits and pieces from others and makes them his own with no understanding most of the time of “Why or how”.

@ DA …so I left out a specific “and accurate” forecast/prediction. His wording is still what I would term very general.
For example, I made a forecast around 13 months ago in which I stated that by the end of this Spring that the oceans ssta would be predominantly cool. So in 3 weeks either I am right or wrong. That is what I call specific. As of now the forecast is certainly getting close to being correct.
“I think this blip ends before NOV. is through and if solar conditions continue to be sub par cooling in a more pronounced way will start in year 2014.”

I am still waiting for Dr Spencer to explain how UAH got the US temperature for April so wrong.
It was one of the coldest Aprils on record (at the 10th percentile) yet UAH had it at only 0.01C below average (compared to NOAAs 1.65C below average for the same baseline).
How can your claim that the satellite record is more accurate than the thermometer record be believed after an obvious blunder like this one?
regional differences can be large, due to atmospheric stability (e.g. cold shallow air masses cooling the surface more than the mid-troposphere).
These effects average out in the global mean, though, so we expect the global anomalies between surface and deep-troposphere to be better coupled, especially if we increase the averaging time from 1 to 3 months (since there is still a time lag for overturning of the atmosphere in response to anomalous surface heating).
This has been well known, for at least 25 years when the satellite monitoring was started. There is no “blunder”.
So what then is the point of publishing this figure?
And why did this time lag not arise for May in the US? Surely May in the US counts as ‘anomalous surface heating’?
The lag only occurs if the deep layer temperature is responsing to the surface, which is more what we expect on very large scales. On the scale of the U.S., the warming surface temperatures might be the result of warm Pacific airmasses dominating over cool Canadian air masses.
You have many questions… maybe get yourself a college-level book on meteorology.
Because it’s an estimate of the average temperature of airmasses over the U.S. during the month, which together with surface temperatures tells us something about atmospheric stability. No one claimed it’s what you measure in your backyard.
Yes, one always enjoys those who believe the world reflects their locale.
But why the US? Why not Africa? Or India? Or a random location in the middle of the ocean? It seems that the only reason you publish this figure is because people DO associate it with the US. So it is misleading.
Lewis
I don’t live in the US. One always enjoys those who make incorrect assumptions based on insufficient evidence.
Bond: Because most of Roy’s readers live in the USA48.
Indeed. Not 7 km above the USA.
So, we can expect an uptick in June globally due to this lag? Northern Europe experienced record high May temperatures this year. Our meteorologists are overwhelmed by the crushing of records in the Northern countries (Denmark, Sweden, Norway, Finland). As a fact, Norway turned out to be warmer than Spain. Norway ended 4.2 C above normal which is a new record. The cause? Massive blocking of high pressure combined with stable low pressure int the south of Europe. And a contention that jet streams are getting more “lazy” due to warming of Arctic (reduction of contrast in temperatures between the tropics and the pole). And again – a product of global warming…
True about Northern Europe and Spain.
In Spain it has been very, very cold. Still is. It’s 21 in Madrid, whereas last year during the first period of June it suffered 43. And forecasts are it will drop next week to 17, way below normal.
All nothing to do with AGW.
@ Pietje …exactly, the sole reason for the warmth in areas of Europe, and the cold in Spain is all about shifting surface winds, and nothing more than that.
Roy…”This has been well known, for at least 25 years when the satellite monitoring was started. There is no blunder”.
You can’t win, Roy. When you guys at UAH report cooler temps than the rest, you get blamed for it, and when you report warmer temps than the rest, you get blamed.
Thanks for this months data. I expected warming and this is good news.
It was unseasonally warm here in Vancouver for much of May but June has begun with cooling (currently 13C). Go figure. Seems like we’re back to normal for this time of year since the 14 day trend is forecasting temps generally under 20C.
“You can’t win, NOAA. When you guys report warmer temps than the rest, you get blamed for it, and when you report cooler temps than the rest, you get blamed.”
ok , nevertheless the trend of late is down which is good, but not down enough.
“Temperatures in response to this will decline in the near future, in contrast to the steady state of temperature we presently have,or have been having for the past 15 years or so.”

David,
No one really appreciates your trying to prove Salvatore has said something in the past which might differ from what he says today.
I, for one, enjoy reading what he has to say and, MOST IMPORTANTLY, the fact he seldom, if ever, attacks those who disagree with him.
SO take a hint. He is a much better person than you.
Lewis: In other words, you don’t care one iota that Salvatore has always been wrong in the past, you’ll entertain whatever inanity he says today.
Why am I not surprised?
Lewis, since I can’t recall a single scientific thing you’ve ever written on this blog, I really could not care less what your opinion of me is.
I’ll keep criticizing Salvatore for all the wrong things he’s said.

Bond says:
I am still waiting for Dr Spencer to explain how UAH got the US temperature for April so wrong.
It was one of the coldest Aprils on record (at the 10th percentile) yet UAH had it at only 0.01C below average (compared to NOAAs 1.65C below average for the same baseline).
Can you please explain your numbers?
For the 1980-2010 baseline, I get these anomalies:
NOAA USA48: +1.30 F = +0.72 C
UAH LT v6.0: -0.01 C
From NOAA’s ‘National Climate Report – April 2018’:
https://tinyurl.com/ybq88kyp
“During April, the average contiguous U.S. temperature was 48.9F, 2.2F below the 20th century average, making it the 13th coldest April on record and the coldest since 1997.”
Their “Climate at a Glance” page confirms this:
https://tinyurl.com/ClimateAtAGlance
Those numbers are with respect to a different baseline — 1901-2000, not 1980-2010.
And I have already said that I converted to the UAH baseline.
NOAA April 2018 compared to 1901-2000 Baseline: -1.20C
NOAA 1981-2010 average in 1901-2000 Baseline: +0.45C
Hence, NOAA April 2018 compared to 1981-2010 Baseline: -1.65C
Converting to the 1981-2010 baseline makes the low anomalies even LOWER.
To get your claimed anomaly of +0.72C in the 1981-2010 baseline would require NOAA’s 1980-2010 average to be strongly NEGATIVE. -1.92C to be precise.
Bryan – oz4caster
I’ve been looking at Climatereanalyzer for a couple of years now, and May, 2018 was by far the coolest month I can remember. It’s surprising that UAH shows almost no change from April.
The trends of late are good but we have a long way to go before I can become more confident.
They are still high even +.18c against 1981-2010 averages is still high. I want to see at least a 0 deviation from that period of time if not below normal.
It is wait and see.
On the other hand this number of +.18c and the last 4 or 5 months argues against AGW which calls for ever increasing global temperatures and as each month goes by without no additional warming it will weigh on AGW.
In addition overall sea surface temperatures are also in a down trend for close to a year now. Again still on the high side more time needs to pass and see what happens.
But it is a start perhaps.
Salvatore Del Prete says:
“…AGW which calls for ever increasing global temperatures and as each month goes by …”
Temperatures went down for thirty years and then the GHE won.
The GHE is long term.
You are short term.
Salvatore del Prete wrote:

Salvatore, when are you ever going to learn about natural fluctuations vs changes in climate.
Personally, I think there’s a reason why you’re opposed to AGW, and it has nothing at all to do with the science or the data.
Why don’t you tell us why you’re really opposed to AGW?
David says: “when are you ever going to learn about natural fluctuations vs changes in climate.”
LOL. This coming from the guy who ignores the AMO and millennial cycle. Why don’t you tell us why you’re really a supporter of AGW?
Salvatore Del Prete says:

It absolutely does not, Salvatore. Shame on you.
Natural variations still exist in an AGW world.
Please go learn something and stop competing with Gordon for the Ignorance Trophy.
DA,
A whole lot of people think Salvatore is wrong. But they don’t treat him like you do. He has an hypothesis, he puts it out there in plain sight. He is always wrong … at least on his timing. It always seems to be “just around the corner”. But he sticks to his theory and doesn’t bother anyone. Who knows. Maybe someday he’ll be right. If you believe there is some science to prove him wrong, why not just state that. Why can’t you be more polite? Why do you have to be an ass? You have a lot of good stuff to say. Why not be know as someone that provides facts and opinions instead of the rude guy?
AGW which calls for ever increasing global temperatures
That is a complete fabrication, Salvatore.
Monthly and interannual fluctuations are EXPECTED under global warming from any cause. What you’ve said just here is complete nonsense.
Salvatore
“which calls for ever increasing global temperatures”
Would you please cite a climate scientist who claims “every month will be warmer than the last”.
If you can’t do this, then fall on your sword and admit to fabricating that BS.
Bond
“How can your claim that the satellite record is more accurate than the thermometer record be believed after an obvious blunder like this one?”
Why are you calling it a blunder? Should we expect the surface and lower troposphere to always match up?
If it doesn’t match up, what is the point of publishing a monthly temperature for a small region of the earth such as the USA? It seems to be an utterly meaningless figure.
bond…”If it doesnt match up, what is the point of publishing a monthly temperature for a small region of the earth such as the USA? It seems to be an utterly meaningless figure”.
You’re an utterly meaningless poster. Who cares what you think?
You are a guest on Roy’s site, have some respect. If you have a question for him ask it intelligently rather than your ham-handed accusations of blundering.
Bond has a good question. You could learn from him, Gordon.
Don’t see that. It’s just different data, measuring different part of atmosphere. Could be useful to know.
We can at least expect UAH’s numbers for the atmo to be close to RSS’s.
But they aren’t — RSS’s trend is about 50% higher than UAH’s for the LT.
DA…”We can at least expect UAHs numbers for the atmo to be close to RSSs.
But they arent RSSs trend is about 50% higher than UAHs for the LT”.
DUH!!!!! RSS has joined NOAA in fudging data so UAH should follow suit?
You’re an idiot.
Gordon, take your lying and dishonesty elsewhere. Start acting like a Canadian.
Another point is people in the climate arena are either unable or not willing to ever forecast a change in the climate in the near future ,if they do it they put it way off into the distant future which is meaningless.
A change in the near future is called weather. Beyond about 10 days, whether is not predictable. It seems you are asking them to guess.
“weather”
Based on previous La Nina years, I predict we’ve reached or nearly reached the minimum for the year. Anoms will go up beginning this month or next.
I do not understand those people that think only one item is going to determine what the climate may or may not do.
Salvatore Del Prete says:
“I do not understand those people that think only one item is going to determine what the climate may or may not do.”
NOBODY THINKS THAT, SALVATORE!!
For crying out loud, it’s difficult to keep up with some of the profound ignorance displayed in this blog’s comments.
@ Nate ..I would disagree with you on the direction of the ENSO regions. The ENSO is now going to return to la Nina conditions, although that may take till the end of the summer.
At best there may be some slight gain in global temps in some of the summer months. After the end of this summer though, then temps are going down slope for the next 3 years approximately, my prediction.
GM,
Its impressive that you can do 3 years. Can you work on my stock portfolio?
Seriously, the ENSO experts seem to think that past 6 months or so, they’re just flipping a coin. How do you do it?
How did I correctly predict in March of 2014 that the winter of 2016/17 would be a well above average rain year for the Pacific Northwest? Along with that, how did I correctly predict that the sunspot numbers would fall close to minimum at the end of 2016 in conjunction with the heavy West Coast winter of 2016/17. How did I also correctly predict in 3/2014 that the ENSO regions would be in a La Nina state in conjunction with a low ssn count, and a heavy winter on the West Coast?
I haf my vays.
GM,
Also, ‘The ENSO is now going to return to la Nina conditions, although that may take till the end of the summer.’
The ENSO modelers find that in the Fall the probability of El Nino or neutral is equal and ~ 45%, while La Nina is ~ 10%.
http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/lanina/enso_evolution-status-fcsts-web.pdf
Do you have some insider info that they don’t?
@ Nate …yes I do have my own special insider views of how the climate system of this planet works. See the above comment for an insight in how far I have come over 10 years of putting my mind to climate related studies.
I guess it will remain mysterious…
Any predictions turn out wrong? Maybe we just dont hear about those?
GM, you’re an “insider?”
Inside of what?
Goldminor,
There are people who swear by astrology, my mother-in-law does Tarot cards, others read palms. The commonality between these is they claim correlation but have no plausible explanation for causation. And they usually report selectively on their predictive success.
If thats what you are doing, claiming sunspots and other parameters correlate to ENSO–but if you have no plausible mechanisms for causation, and you report selectively on your record of predictive accuracy, then why should we not lump your predictions in with astrology and the others?
nate…”Based on previous La Nina years, I predict weve reached or nearly reached the minimum for the year”.
Who said La Nina is the driver? The average for 18 years from 1998 – 2015 was around +0.15. The temps are just approaching that average again.
That’s your prediction? Lets see who does better.
“weather” and natural fluctuations.
Or, ENSOs = weather in the ocean.
ENSO is not all, but pretty dominant over short periods.
ENSOs can easily cause global average temperature swings of +/- 0.1-0.4 C in ~ six months.
The real question to be answered is why the ENSOs keep getting warmer, in all its phases — El Nino, La Nina, and neutral.
Because more solar short wave radiation has penetrated into the ocean from an unchanged Solar constant at top of atmosphere because of the reduction in low level cumulus cloud from at least 1984. More solar into the ocean, more energy for both El Nino and La Nina to play with.
I just contradicted myself, didn’t I? Guess I shouldn’t be too surprised that the surface change from April to May was more pronounced than at the LT.
Sal
What are you talking about? People in the “climate arena” are predicting a modest, short term warming trend as a result of the la nina fizzling out.
True enough . We have to see what happens I think we find out much in the next year or two.
Yet again, Salvatore, you’re changing the goalpost.
“…if temperatures do not show a decline by then(summer of 2018) in conjunction with very low solar activity we will be in trouble with our global cooling forecast.”

“If it doesnt match up, what is the point of publishing a monthly temperature for a small region of the earth such as the USA? It seems to be an utterly meaningless figure.”
If I understand correctly, satellites average the column of lower troposphere rising above an area like the United States. This might not match surface measurements in a particular month, but they correlate well in the long term.
In my opinion, two areas measured (surface and lower troposphere) are better than one, and the fact that they generally agree gives credence to both records.
(For some reason, I am only able to post at the bottom of the page)
Snape says:
“For some reason, I am only able to post at the bottom of the page”

Snape says:

Not really. There is a vertical weighting function that must be calculated first.
The cool water pool just south of the equator looks like it could diminish the warming impact of the equatorial undercurrent warm pool that is making its way east and to the surface — the trade winds are blowing slightly south to north.
By this time last year the warm pool had already reached the surface and was warming the atmosphere, but if it doesn’t do the same this summer then a similar or sharper cooling trend compared to 2000-2013 could be developing and the pause could return by 2019 or 2020.
Dr. Spencer,
I still can’t help from noticing how the global mean temperature anomaly of the Tropics have been consistently lower than that of the globe during the past 17 months. Only 3 of the past 17 did the Tropics show a warmer temp anomaly.
I’ve always suspected that what is going on in the Arctic has a lot to do with what is going on in the Tropics. If you look at the Arctic, it has been considerably higher (not every month) than the globe. This leads me to believe that the Arctic is “pulling” heat from the Tropics during this period of time.
Do you think that is happening? Or, is it just statistical noise.
Rob, See for example https://en.wikipedia.org/wiki/Polar_amplification
So, are the tropics always going to show a lesser temp anomaly than the globe? Or, does it oscillate. I would think that Tropics would show a higher temp anomaly than the globe when the Arctic is in a cooling trend. Whatever the mechanism is that transports heat to the Poles will sometimes be weaker in some decades, allowing more heat to stay in the Tropics, thus cooling the polar regions. Probably much more noticeable in the Arctic than the Antarctic.
Rob…”So, are the tropics always going to show a lesser temp anomaly than the globe?”
The UAH 33 year report from 1979 to about 2011 seems to indicate that. Little or no warming in the Tropics.
Gordon, thank you for the UAH link. The point I was making is that before 1979, the globe was in a cooling trend. So, I was entertaining the thought that if we had UAH data BEFORE 1979, it would probably show higher temp anomalies for the Tropics during the global cooling phase of the 1940s through the 1970s than what is indicated now by satellite measurement. Reason being is that more heat was bottled up in the Tropics during the mid-20th Century cooling trend of the mid-lats and polar regions.
After 1979, the warming phase kicked in at the same time satellite data was used to measure tropospheric temperature as developed by Spencer and Christy. It just seems to me that heat stored up in the Tropics during the so-called “cooling” phase of the 20th Century is being released to the mid-lats and poles, producing a so-called global “warming” phase.
I know I am probably over-simplifying things, but it looks like to me that multi-decadal warming and cooling phases are basically driven by how much heat transfer is going on from the Tropics to the Extratropics.
@ R Mitchell … the tropics do not vary much due to the relationship with ocean temps and cloud formation which cools the oceans surface. W Eschenbach did a post at WUWT around 5 years ago which explains the process. Heat transfers from the Equator to the poles mainly due to the spin of the planet.
Check out the major ocean currents to see how warm waters are transported continuously to the polar regions. Also air currents perform a similar function in transporting heat to the poles, and then to space.
Yes, there is the spin of the earth. But there is also heat transport from the equator to the poles just as heat transports along a metal rod when you stick it into a campfire. Have you ever seen the rotating dishpan experiment of the 1950s?
I would not consider ocean currents and air currents to be a constant any more than I would consider solar radiance a constant. There are going to be some decades when the heat transfer from the Tropics to the Poles will be a little higher than normal, and some decades when it is a little less than normal.
Due to baroclinic zones of the Extratropics, naturally there will be greater temperature variation there. So, when the Extratropics are in a “cooling phase,” I would think the Tropics would show plus temperature anomaly figures compared to the globe.
Av temps in the tropics change less than mid and (Northern) high latitudes in multidecadal response to a general change in climate.
Eg, during the last few ice age transitions, the polar temps changed by about 10-12C, the global average by 5-6 C, and the tropics by about 2-3C.
I was thinking of a much shorter time scale than the glacial-interglacial ones. More on the order of a century. I am curious what Dr. Spencer’s and Dr. Christy’s UAH data would have looked like from the 1940s through the 1970s. I would suspect you would see higher Tropical temp anomalies than the polar regions because less heat was being transported to the poles back then compared to the recent decades. The poles, especially the Arctic was probably colder back then because the Tropics was retaining more heat than it is now. The Arctic has warmed in recent decades probably because the Tropical region is sending more heat there than it did during the middle of the 20th century.
rob…dig through this site and you’ll see temperature contour maps going back to 1979. The few I have seen, including January 1979, showed no warming and/or cooling in the Tropics.
https://www.nsstc.uah.edu/climate/
Bottom line, so-called “global warming” could very be just a multi-decadal phase where the Tropics is being more efficient at transferring heat to the Poles than normal.
Robert
Here is the latest animation of the “equatorial undercurrent warm pool” you mentioned. Looks like it’s starting to make its way to the surface.
I don’t think anyone can predict what happens after that.

So, for the first time in 3 years UAH is below 0.2.
Yet still 0.09 C above the 30-yr mean, and 0.09 C above May’s value 30 years ago.
Krak…”So, for the first time in 3 years UAH is below 0.2″.
Yup…that was a long El Nina from Feb 2016 on.
Curious to see if the big EN’s have petered out.
Eystein, from upthread:
“contention that jet streams are getting more lazy due to warming of Arctic (reduction of contrast in temperatures between the tropics and the pole).”

Bullish for cooling. The question is does it last?
Salvatore, why do you prefer cooling over warming? What is your philosophical/personal reason for opposing AGW?
@ DA …none of us prefer cooling over warmer, but if it will finally put an end to the inane ‘CO2 is a main driver’ meme then let the cold reign to put out the lukewarm fire of AGW.
Why is that inane?
Why do you care if it’s true?
@ DA …I care about science among other things in life, always have. I view the AGW story as a false paradigm. Thus, if it takes a moderate cold spell to put a stake through the heart of AGW, then let it be so.
Besides all of the above, my view from the reading and studying over the last 10 years leads me to agree with nature now heading into a moderate cold trend which will last into the early 2030s, imo. Then there is a possibility that a second 30 year cold trend will follow. I would state the probability of the second round as 50/50. The first segment is already underway, imo.
I would also bet that this last leg of warming will be seen as the peak of the Modern Warm Period when scientists look back from the view pint of 2200.
I think you don’t understand the physics of manmade global warming — why it MUST keep getting warmer.
You didn’t mention anything about greenhouse gas emissions….
@ DA …I did not mention increasing levels of CO2 as I see that as a bit player in the climate system which is always easily overwhelmed by natural processes.
I also think that in another century or more that scientists will look back and see the peak of the Modern Warm Period as occurring from 1980 to 2016.
GM, I’m not interested in your opinions, I’m interested in what you can prove.
Can you prove even one of your claims above?
@ DA …from 3 years ago, …https://disqus.com/home/discussion/cnbc/sierra_nevada_snowpack_lowest_in_500_years/#comment-2253607967
@ DA …from 4 years ago, not clearly stated. Otherwise the comment is saying that the winters of 2014/15 and 2015/16 will see average to slightly above average rains to Northern California, and the pacififc Northwest. At the time which I made this comment the consensus was that the California drought was likely to continue for more years. I was the only one to state differently.
Then the last part of the comment is stating that the winter of 2016/17 had a strong probability of being a flood winter for NOrthern California and the PNW. All of that came to pass. Not stated, but essential to the predictions was that sunspots would be close to minimum levels, and the ENSO would have yo be in a La Nina state for the flood winter to take place. That is because it is a cyclical process. The next similar winter will most likely be in the winter of 2026/27, with a lesser probability for the winter of 2025/26. …https://disqus.com/home/discussion/cnbc/california_rice_farmer_039probably_sell039_due_to_drought/newest/#comment-1583227008

https://www.climate.gov/news-features/blogs/enso/why-did-it-rain-so-much-california-during-last-year%E2%80%99s-la-ni%C3%B1a
The wettest years are often strong EL Nino, but correlation is far from perfect.
@ Nate …thanks for the link. that is interesting to me to see how NOAA looks at this. Take a look though at solar and ENSO conditions in 2 of the largest floods after the Ark Storm of 1862 to ever strike Northern California. Note that in NOAAs page they reference rainfall for 4 cities. I am not talking about the cities, but rather the coastal mountains and Sierras.
So the Ark Storm is the Big One in 1862. The next biggest was the storm of 1964/65 which impacted from just south of San Francisco all the way into southern British Columbia. After that was a very strong storm in 1955/56 which did not have quite the stretch of 1964/65, but was still very significant for NorCal, Oregon and southern Washington.
I knew of those from growing up in California, and had heard back in the 1970s that it was thought that there was a cyclical pattern to the coastal mountain floods of the PNW. It isn’t as clear cut though when looking back in time, partly as records get scarce for some of the past data. But that is the basic info which I then built upon to derive the probability of a heavy winter for NorCal, and the PNW for 2016/17. Now I have to wait until 2026/27 to see what happens next. Will there be a La Nina, and ssn count close to minimum then? It is an interesting thought as it could lead to some level of predictability for the ENSO regions and sunspots as well as for large rain/snow years for the West Coast.
@ Nate …also of interest is that there are a number of examples of a heavy winter impacting Southern California in the following winter after a flood winter in the North. Also another example of flood winters for both north and south. The winter of 1996/97 was semi-biblical in the north. The next year the south was inundated. The same happened in 1965/66 after the great flood of 1964/65. Also in 1956/57 after 1955/56. So there is some pattern within all of this. There are more examples as well.
GM, Looking at the longer view pattern, N Cal wetness for 5 y periods (from NOAA), it is clear that the wetest were in 80s and 90s, and driest were 20s and 30s. Wet again in early 40s.
The 80s and 90s had a string of strong El Ninos, while the 20s and 30s were an extended period of La Ninas. In 1940-42 was an extended El Nino.
My studies right or wrong have led me to this conclusion and now they will be tested.
Salvatore, you’ve already been wrong many times before, but you learn nothing from them.
@ DA ..well we can agree on some things.
Ocean trends bullish for cooling?
https://www.tropicaltidbits.com/analysis/ocean/global.png
Oh dear … I thought for a moment Barry was swearing. Time to get my glasses checked.
I say what is going on with the North Atlantic is as much a climate driver as is ENSO. Yet the former seems to be largely ignored.
“Your conclusions are in a word wrong, and that will be proven over the coming years, as the temperatures of earth will start a more significant decline (which started in year 2002 by the way)….”
– Salvatore del Prete, Reply to article: IC Joanna Haigh – Declining solar activity linked to recent warming, 10/8/2010

That’s right Salvatore, the AMO is about 60 years, so it can run against AGW for 30 years. In the end it’s +/- 0 while CO2 lasts for millenia and we keep adding.
Salvatore, ENSO isn’t a climate driver, it’s a natural fluctuation.
WHen are you ever going to learn the difference between a forcing and a fluctuation??
I would say the North Atlantic is as important a climate driver as ENSO.
@ S.P no, the ENSO is primary and the Atlantic is secondary. I could explain, but I would not want to give you any more ideas which you can’t comprehend on your own.
I disagree.
That may be so, but you are unable to explain why you think the Atlantic is primary. There are multiple reasons why it isn’t, and that includes one very obvious fact which anyone should be able to understand.
Salvatore…”I would say the North Atlantic is as important a climate driver as ENSO”.
Tsonis et al revealed that a long time ago, that all the ocean oscillations work with each other or against each other to produce the climate.
The AMO is multidecadal, however, and the PDO is decadal. ENSO is shorter term but the PDO affects La Nina and the strength of EN depends on it too.
A lot of unproven claims in your last paragraph.
Can you prove any of them?
One of them?

Sure ENSO is more important
ENSO I sonly important when the climate is in a given regime it has no ability to change the climatic regime the climate is in.
Contrast that to the North Atlantic and you will see what I have said is correct.
The above post is my answer to Mr. Goldminer.

“I think you dont understand the physics of manmade global warming why it MUST keep getting warmer.”
Any person professing to be a scientist, who makes a statement like that, is absolutely some fake.
By simple analogy, using a magnifying glass to make a hot spot has a reaction in physics that suggests the atmosphere should be getting warmer as you do this. But that would be ignorant, because we are in an atmospheric system that has the ability to redirect energy so that an overall system warming is NOT inevitable. Without these redirection mechanisms, the atmosphere would keep getting hotter. In real life, it adjusts to anomalous heat sources over times of various lengths depending on the specifics of the mechanism.
It is so fake to imagine that a CO2 molecule can heat the atmosphere, while the heat from a magnifying glass is different.
Geoff
I see you are not a scientist.
Bond,
I see you and raise you $50 billion US. That figure is about the value of metal sales to date from the several new mineral discoveries, now mines, found by Geopeko, a small exploration group that I had the honour to help manage as Chief Geochemist for 15 years or so. These brand new discoveries were made by the application of good, disciplined science.
Money is one way to quantify success.
Bond, what has been your monetary measure of success in science?
Geoff
@ G.S. …+100
@ GS + 50000000
‘These brand new discoveries were made by the application of good, disciplined science.
Money is one way to quantify success.’
And no one should dispute your success and expertise in this area of science. Im sure you have years of experience and education.
But why do you guys unflinchingly question the expertise of climate scientists? These are people who have way more expertise in their subject than any bloggers.
They also have a strong track record of success, eg in understanding the atmosphere, predicting weather, hurricane tracks and climate change, and advancing remote sensing technology. 38 y ago, the climate change over that period was accurately forecasted.
‘It is so fake to imagine that a CO2 molecule can heat the atmosphere, while the heat from a magnifying glass is different.’
I agree with Bond. This just doesn’t make a lot of sense.
Nate,
The magnifying glass appears to create heat, but it does this by also creating cool, like some rays are enhanced in energy while others are reduced, like a dimming.
The CO2 molecule as typically portrayed is said to create heat, but it also creates cool. The energy it absorbs prevents some of that energy from going elsewhere, like a dimming.
If you argue that the magnifying glass observation is immaterial, then the same applies to the CO2 case, does it not?
Geoff
‘but it also creates cool. ‘
Yes indeed it does, in the stratosphere, as predicted and observed.
CO2 is not creating heat or cool, it is acting as insulation. Just like adding attic insulation in my house. The house warms and the attic cools, assuming the furnace heat output is kept fixed.
Geoff Sherrington says:
The CO2 molecule as typically portrayed is said to create heat, but it also creates cool.
No, CO2 neither creates heat nor “cool.”
You need to go back to the basics and relearn and get this right. You won’t understand anything about global warming until you do.
@ Nate ..in reply to our discussion further up the page. We are not talking about the same phenomenon. I am talking about the largest storm systems which have negatively impacted the West Coast. While you are talking about the wettest periods on the West Coast. Those are different topics of discussion. That is where the confusion stems from.
Ah, OK.
But how can you or anyone predict when a large storm will come?
One can only predict when rain is more likely.
Geoff wrote:

No one thinks the first.
And, yes, physics has been requiring that the lower atmosphere get warmer. The surprise would be if this WASN’T happening.

“Snape says:
If I understand correctly, satellites average the column of lower troposphere rising above an area like the United States.

Isn’t that a weighted average?
Yes.
–Climate models vs. climate data: A THOUGHT EXPERIMENT
Guest Blogger / 2 hours ago June 1, 2018
Guest essay by Bob Irvine
Is it true that energy from either an outside source or an increase in insulation will warm a system according to or in proportion to its residence time in that system?–
https://wattsupwiththat.com/2018/06/climate-models-vs-climate-data-a-thought-experiment/
Snape might like this.
I thought this was interesting:
“5. Nearly all sensitivity studies base their feedbacks on the assumption that GHG and solar efficacy are approximately equal. The IPCC states this in their reports. The feedbacks used are then feedbacks to an initial warming while feedbacks related to the intrinsic nature of the forcing and its mechanism are not normally considered. In particular, changes in residence times for energy from the different forcings do not appear to be considered. ”
If true, it could be due, to idea the only thing which can increase average global temperature are greenhouse gases.
Which indicates the power of the pseudoscience is a great force.
Let’s not blindly swallow anything and everything written on a denier site like Watts’, alright?
Can you find this statement anywhere in the scientific literature?
Gbaikie
Thanks for the link. Maybe I’ll join the conversation over there.
There is no trend in this satellite data other than what people imagine , what you have there is fractal noise, as long as the high peaks and low peaks overlap you don’t even begin to have a trend. The only real trend that will eventually appear will be downward and into the ice age.
Fractal noise?
Any set of numbers can be used to calculate a linear trend. And also its Pearson coefficient and statistical significance, as well as the standard error of the trend number, without or with correcting for autocorrelation.
Obviously you do not understand the concept of noise , If the temperature variations are 1,5 degrees within few years as seen in the 40 year chart , then anything under 1.5 degrees on a 140 years scale or 1400 years scale is nothing but noise , not trend , Your claim of calculating trends from any set of numbers is only an artifact of picking a starting and ending points.
Eben says:

Sorry, no.
Noises tend to cancel out over useful trend lengths, leaving the only uncertainty to be statistical.
Please explain how 80 years period of the multi decade ocean oscillation cancels out in a 40 year old satellite record ???
“Sorry, no.
Noises tend to cancel out over useful trend lengths, leaving the only uncertainty to be statistical.”

Trend or no trend in surface temp?

I tried posting (for the time) on WUWT, but nothing showed up.
What’s up with that?
(for the first time)
@ Sbape, aka Snape, it has to do with the new migration to a new WordPress platform. Check back and the comment should eventually appear. Not sure how or why, but there it is. I have had a few comments enter immediately, and others appear later.
No, the site is moderated. Wait, and check back later to see if its been admitted.
@ barry ..yes the site is moderated, but my original answer still stands as correct. It had everything to do with the transfer to the new platform. There is a new post today stating that the transfer finally completed as of today.
Ok, thanks
It’s a moderated site. Wait for one of the mods to admit the post.
Also, they block anyone who knows anything.
@ DA ..still sore after all of these years because WUWT blocked you? Are you saying that Nick Stokes and Steve Mosher do not know anything, among some of the others who argue for AGW yet comment at WUWT?
@ Snape, aka Sbape, …WUWT just made another change to their comments section. They now allow for 15 minutes of editing a comment, voting for comments, and easy picture installation within comments. Pretty good once one gets used to the change.
Where is ren? I need my update on how strongly negative the Arctic Oscillation is. It is still negative, right ren? Because your unbiased reporting would have kept us informed had the AO gone positive?

I guess there are no reports to make on an influx of Arctic air into the US.
“The linear temperature trend of the global average lower tropospheric temperature anomalies from January 1979 through May 2018 remains at +0.13 C/decade.”
It explains the manic posting from the antihuman climate alarmists.
Thanks for the update, doc.
The trend in RSS TLT over the same period is +0.19 C/decade. Warmer even that GISS surface temperatures, but in the same ballpark.
Either UAH or RSS (or possibly both) are interpreting the satellite data incorrectly at the moment.
And that is the whole point, isn’t it. The satellite data is up for interpretation, and is not a precise measurement.
Seems to be the case. The changes made between updated versions of the satellite data sets seem to be of a greater magnitude than those made between updated versions of the surface sets. The two main satellite data producers also disagree with one another more than the various surface data producers. It’s no doubt a very difficult task for the satellite teams, but it’s pretty clear that something isn’t right somewhere at the moment.
I think you will find that one of the satellite groups will agree with you that it is a difficult task, with a very wide margin of error, while the other will assert that all the glitches have been ironed out and theirs is a near-perfect record.
Bond notes margins of error etc with condensed first hand wisdom that permits him to create criteria to favour cv RSS over UAH.
Bond, what is your take on how important your commentary is?
Personally, I am grateful for the scientific pioneering by Spencer and Christy and would suggest that their scientific integrity is beyond reproach because inter alia they have paid homage to fundamental scientific philosophy.
They can proceed without your less informed comments from the sidelines that seem to be spiteful innuendo and little more.
Geoff
You took from my comment that I favour one data set over the other? It seems your comprehension skills are lacking.
Bond,
But, do you or do you not favour one group over another?
Your comment is merely evasion. Geoff

THanks.
@ Bond …yet despite that the sats somehow sense the vast surface of the always moving oceans to within a millimeter of precision, and AGW believers all accept that as gospel.
Why do you think the satellite designers were so wrong? I mean, what did they botch up in their analysis?
@ DA …you should ask that question to the ones above who think that there is a problem with the sats.
Not all SATS methods created equal.

Not sure where you’re getting that from? Winters (Dec-Feb) in USA48 have warmed at a rate of 0.17 C/decade. Pretty much as fast as the annual rate.
@ Bond …ren still has a point. April US temps were record setting cold if I remember right. The same can not be said for Australia temps in April. I think that Australia is going to experience well below average temps this winter, alomg with NZ and the extremities of Africa and SA. The surface wind changes down there guarantee that, imo.
You recalled incorrectly.

The Arctic region (60N-82.5N) was in 2017-2018 by far not so warm as during previous winters, as shown by the GHCN V4 daily record since 1881 (no offical data, it was processed by my friend).
A sort of the anomalies (wrt the mean of 1981-2010) is as follows:
1881 | 11 | 6.35
1881 | 12 | 5.49
1882 | 1 | 5.38
2016 | 2 | 4.51
1883 | 11 | 4.39
2017 | 12 | 4.33
1885 | 7 | 4.09
1882 | 8 | 4.08
2006 | 12 | 4.04
1882 | 2 | 3.81
In this sorted list, 2018 appears at position 64 (of 1648).
Even if you consider only the satellite era, 2018 is absent from the top 10:
2016 | 2 | 4.51
2017 | 12 | 4.33
2006 | 12 | 4.04
2015 | 2 | 3.81
2011 | 12 | 3.56
2014 | 12 | 3.42
2015 | 3 | 3.27
2014 | 2 | 3.22
1981 | 1 | 3.19
2015 | 12 | 3.17
And the same is shown by UAH Arctic 60N-82.5N land-only:
1981 | 1 | 2.62
2016 | 1 | 2.53
2016 | 4 | 2.05
1980 | 2 | 1.88
2012 | 6 | 1.74
2017 | 12 | 1.60
2016 | 2 | 1.53
2016 | 3 | 1.46
2017 | 3 | 1.46
2007 | 4 | 1.43
But this absence of 2018 at ranking top is not due to the anomalies.
A sort of absolute GHCN V4 daily Arctic data in the ‘colder’ months November-April during 1979-2018 gives this:
2016 | 4 | -0.60
2007 | 4 | -0.93
2010 | 4 | -1.35
2011 | 4 | -1.55
2015 | 4 | -1.60
1990 | 4 | -1.64
2014 | 4 | -1.81
1994 | 4 | -1.83
1995 | 4 | -1.97
2005 | 4 | -2.18
April 2018 appears here with -4.14 C at position 32 (of 238).
Thus in the sum I wouldn’t say that winter 2017/18 was ‘pretty warm’ in the Arctic.
binny…”The Arctic region (60N-82.5N) was in 2017-2018 by far not so warm as during previous winters…”
No kidding, where do you think the freezing air came from that set records for cold in much of the United States?
Sorry Gordon, there was no cold record set for the US.
In fact, this meteorological winter (DJF) for USA48 surface temperatures was 24th highest out of 123 DJFs. Top 20%.

Mamma mia, Salvatore! Why do you pretend things without having ever had a look at them?
Bond is absolutely right: anomalies below average for summer months since 2010 are in UAH’s Arctic record an exception.
1. Here is the top 20 of the ascending sort of all negative UAH Arctic anomalies since 1979:
1989 | 1 | -1.98
1979 | 2 | -1.71
1985 | 4 | -1.55
1990 | 11 | -1.34

1980 | 11 | -0.99
1993 | 1 | -0.96
1986 | 3 | -0.96
2. Conversely, here is the top 20 of a descending sort of all summer month anomalies in UAH’s Arctic record (I even included September to Bond’s list):
2012 | 6 | 1.44
2016 | 9 | 1.24

1997 | 9 | 0.59
1995 | 8 | 0.58
2010 | 7 | 0.56
1998 | 8 | 0.55
The first negative summer month anomaly appears at position 89 of 156.
Why don’t you download the data, Salvatore?
http://ocean.dmi.dk/arctic/meant80n.uk.php
This data show what I say to be true.
You tell me.
So you compare ONLY 2017 temperatures to the mean, and assert that this result holds for ALL summers.
Will your cherry picking ever end?
OK, I just noticed that you can also look at other years.
I also clicked on the link at the bottom of the page where it says “More information can be found here.”
It says “since the model is gridded in a regular 0.5 degree grid, the mean temperature values are strongly biased towards the temperature in the most northern part of the Arctic! Therefore, do NOT use this measure as an actual physical mean temperature of the arctic.”
The area covered by these graphs is only 18% of the area of the Arctic.
Salvatore Del Prete says:
June 2, 2018 at 6:52 AM
Sorry, Salvatore: wrong again.
Simply because you look at the northernmost part of the Arctic (80N-90N) instead of considering the whole Arctic (60N-90N).
And I thought you trust only in Roy Spencer’s satellite data!
As Mr Spencer publishes 2.5 degree grid data for the whole Globe, you may exploit that data, e.g. for the latitude band 80N-82.5N, compute a time series out of it, extract all summer anomalies, sort them, and display their top 20:
2012 | 6 | 1.63
2016 | 9 | 1.62
1995 | 9 | 1.57
2007 | 6 | 1.48
1999 | 7 | 1.41
2015 | 7 | 1.41
2010 | 6 | 1.36
2011 | 6 | 1.32
1990 | 8 | 1.29
2011 | 8 | 1.26
2005 | 6 | 1.24
2008 | 8 | 1.24
2011 | 7 | 1.22
2017 | 9 | 1.22
1999 | 8 | 1.19
1998 | 8 | 1.17
2012 | 9 | 1.16
2008 | 9 | 1.15
1990 | 9 | 1.14
1991 | 9 | 1.11
As you can see, the summer anmomalies are here even higher than for the whole Arctic (60N-90N). And here as well, the first summer anomaly below average is far far away.
A little hint: the northernmost Arctic is that region of the Globe where the lower troposphere warms the most since 1979.
The trend there is not 0.25 C / decade like in the Arctic, it is 0.44 C / decade.
Yes I only trust the satellite data but his data does not cover the area the Danish data covers so I use that. That data has shown very warm Arctic winters and cool summers hardly what I would like to see.
Why do you only trust satellite data?
And within that, why do you ignore RSS?
Is it correct? What do you think?
DMI Arctic analysis is of the Arctic 80N and up, nothing below. It covers less then 20% of the Arctic.
It is not a good proxy for the whole Arctic from 60 or 66 North.
One reason for this is that most of the sea ice above 80N is perennial – even during Summer minimum there is a lot of ice there.
Whereas the sea ice between 60 and 80N is highly volatile (seasonal).
A consequence is that at 80N Northwards, the near-surface air temps during summer hover very close to 0C – which is the temperature of the surface of the ice.
80 n or better and this is important because it shows how warm this area is in winter , and yet it does not continue into the warm or summer season.
I think it is valuable information which debunks global warming to some extent.
Please explain how this “debunks” global warming.
In answering, make sure you use the correct definition of global warming, and not a straw man version.

It is the number of days the temperature stays below freezing (summer temperatures)in the HIGH ARCTIC that will determine Arctic Sea Ice, which is never going to melt away. Never.
As far as La Nina, the tendency is still leading toward La Nina, rather then El Nino.
However, that does not matter in the scheme of things. What matters are the overall sea surface temperature which are in a down trend.
North Atlantic in particularly.
That is what I am watching.
In the meantime this year thus far has not been a good year for AGW ,because temperatures have failed to increase and if anything have fallen.
Each day that goes by without global temperature increases will damage AGW.
We will be finding out soon how much or little AGW theory has going for it.
All the above my opinion we will see if it is correct or not.
I’ve said before, I am not going to read blog ‘science’.
Whether or not you believe that this ice will ‘never melt away’, how exactly does that disprove global warming?
Salvatore…”I think it is valuable information which debunks global warming to some extent”.
There was no science to debunk, Salvatore. No one has ever proved CO2 warms the atmosphere, it’s sheer conjecture based on consensus.

Thanks ren for proving with that graph that your claim about La Nina continuing is nonsense. It shows the tropical Pacific neutral or higher, with the cold water that was previously there now dispersing to the south, in much the same way the warm water dispersed after the last El Nino.
Idiot tracker
My comments are so far not appearing at WUWT, so I am replying to one of your post’s here:
“The black box warms merely because it absorbs more incident energy than the white box. So its temperature must eventually get warmer in a steady state so that its heat loss to surroundings equals the greater amount of heat it absorbs. As simple as that.
And Hansens climate response time has nothing to do with a claimed energy residence time. Utter confusion here. The latter concept is quite meaningless, you cannot label and track heat, just count how many goes in or out of system per unit time. Good old Thermodynamics.”
Rate of input and residence time (I’ve called it “length of stay”) are the two variables that determine how much of something will have accumulated when a steady state is reached.
Hard or impossible to measure, so yeah, meaningless WRT calculations, but not actual meaningless since it’s a real and important variable.
Rate of input and residence time (I’ve called it “length of stay”) are the two variables that determine how much of something will have accumulated when a steady state is reached.
“Something” such as people walking in and out of a room, certainly, but not heat or energy exchange of a system.
What would be, according to you, the time of residence t of energy in a system ?
There is no pertinent physical meaning of t, nor is this a description of what happens to a quantum of energy that enters the system. Such a quantum cannot be tracked anyway and certainly cannot be said to stay there for a time t and then leave again. This picture is not appropriate at all. What happens at microscopic scale and relevant physics is that energy is exchanged very rapidly is both ways across any interface between the system and surroundings. For instance molecules of air bounce off the ground and so either lose or gain energy at the 10^-10 s scale. And the global net exchange is only determined by differences in temperature, and this is all we need to know to find out how much energy accumulates into a system in a steady state.

Salvatore,
80 n or better and this is important because it shows how warm this area is in winter , and yet it does not continue into the warm or summer season.
“DMI Arctic analysis is of the Arctic 80N and up, nothing below. It covers less than 20% of the Arctic.
It is not a good proxy for the whole Arctic from 60 or 66 North.
One reason for this is that most of the sea ice above 80N is perennial even during Summer minimum there is a lot of ice there.
Whereas the sea ice between 60 and 80N is highly volatile (seasonal).
A consequence is that at 80N Northwards, the near-surface air temps during summer hover very close to 0C which is the temperature of the surface of the ice.”
I got much of this from an email DMI sent in reply to my queries about summertime temps staying around zero C each year in their charts.
I’m quoting myself there, BTW. I can probably dig up the original email from DMI if requested.

LP, Barry
Thanks for the information about the arctic.
Thanks in turn to Dolores Umbridge for this encouraging message.
The data from 80 n to 90 n is important. The data everywhere is important.
As far as what I think will determine the end of AGW ,it is not so much the number of years the global temperatures do not rise or even fall but rather the magnitude of the fall and quickness if it should occur.
In other words if global temperatures were to take a sudden turn to the down say .5c or more in less then 2 years that would be more telling then if global temperatures even did not rise or had a gradual drop for several years.
If global temperatures should take a sudden down turn AGW is over regardless of the duration of time associated with the sudden down turn.
Data from only 0.75% of the globe does not outweigh the other 99.25%. Especially when the effect you have notice only applies for one third of a year, so you are effectively saying 0.25% outweighs 99.75%.
I did not say that at all.
What matters is the temperature for the WHOLE globe.
Aha.
Would you please performn a review of all the comments you sent during the last 24h?
Yes, the AVERAGE temperature for the WHOLE globe.
Fortunately for Salvatore, global warming ended 16 years ago.

Climate Data Doesnt Support CO2 Driving Climate Change and Global Temperatures
https://co2islife.wordpress.com/2018/06/03/climate-data-doesnt-support-co2-driving-climate-change-and-global-temperatures/
When will you be submitting this to a major scientific journal? (Prepare for a press onslaught.)
There’s a Nobel Prize in this for you — you ARE aware of that, right?
Sadly, nothing I write would ever pass the corrupt peer review process. Care to refute a single claim I make?
CO2isLife
A lot of what you post on your blog can be refuted.
YOUR MAIN POINTS:
1) The only defined mechanism by which CO2 can affect/cause climate change is through the GHG Effect and thermalization of 13 to 18 LWIR.
Not exactly. It is more the energy it is able to emit back to the surface that will cause global warming.
In the graph you use to show GHG cooling, you should not that in the lower atmosphere H2O and CO2 are close to zero effect for cooling or heating the atmosphere.
http://www.atmosp.physics.utoronto.ca/SPARC/News17/ReportTropopWorkshopApril2001/17Haynes_Shepherd.html
They both absorb energy (heating effect) and radiate energy (cooling effect) and the sum is about no net heating or cooling of the atmosphere. Yet that has little to do with GHE or global warming. Not even sure what your point is with this graph.
Here is a more important graph.
https://www.patarnott.com/atms749/images/MeasuredRadianceReno.jpg
This energy that is emitted by CO2 is what will allow the surface to reach a higher equilibrium temperature with the same solar input.
CO2isLife
YOU also state this:
5) 13 to 18 LWIR does not penetrate or warm water.
Nor does it penetrate any solid material. Yet is can warm a object but it can’t warm water? Why do you make this claim. Water absorbs IR very well. What do you think happens to the energy absorbed by water?
It can warm a wall but can’t warm water? Why?
CO2isLife
YOU:
7) H2O/Water Vapor is by far the most abundant and potent GHG, and it also absorbs 13 to 18 LWIR, making the contribution of CO2 immeasurable in the atmosphere until the altitude of 3 km is reached and H2O starts to precipitate out of the atmosphere.
You really think you have your science right with this one?
http://www.meteor.iastate.edu/gccourse/forcing/images/image7.gif
Actual science shows your understanding is not correct. CO2 absorbs about 100% of the IR at the 15 micron range while water vapor absorbs around 50% even with its high concentration. If no CO2 were present you would have considerable IR leaving the Earth’s surface through space at this wavelength.
CO2isLife
You may have a case that politicians and other vested interests are manipulating climate science for some agenda (like Al Gore who got very wealthy from his Green agenda).
I do not believe the science is faulty as you do. If you take the time to read the actual science material and not the politician or media version they sound like good scientists.
I do not think any of your ideas contained here are at all valid.
YOU: “The problem with Climate Science is that it isnt science. Climate Scientists are all out there trying to PROVE CO2 is the cause, their livelihoods depend upon it. Real science is the unbiased search for the truth. Real science seeks to understand and explain, not prove one theory over the other. Real science never proves anything. Real science rejects the null/consensus, it doesnt PROVE the cause, it PROVES the currently accepted cause is wrong. Real science shatters the consensus, it doesnt seek to defend it. Climate Scientists are practicing Anti-Science, Climate Sophistry, and Propaganda, and the above graphics and analysis prove it.”
Climate science is a science. It goes out in the field and takes many measurements and attempts to related the findings. I can’t see why you would suggest that is not science, it is in my book.
I think this is an unfounded rant. More trying to appeal to an emotional state than a rational logical one.
Norman Says:
“1) The only defined mechanism by which CO2 can affect/cause climate change is through the GHG Effect and thermalization of 13 to 18 LWIR.
Not exactly. It is more the energy it is able to emit back to the surface that will cause global warming.”
CO2isLife: I think that goes without saying. That is the GHG effect, however, energy is radiated and diffused in a 360 degree sphere, so only a fraction goes back to earth.
Norman Says:
“In the graph you use to show GHG cooling, you should note that in the lower atmosphere H2O and CO2 are close to zero effect for cooling or heating the atmosphere.”
MODTRAN clearly shows H2O dominates the lower atmosphere as a GHG, and CO2 only becomes a factor up around 3km and higher when H2O precipitates out of the atmosphere.
Norman Says:
“YOU also state this:
5) 13 to 18 LWIR does not penetrate or warm water.
Nor does it penetrate any solid material. Yet is can warm a object but it cant warm water? Why do you make this claim. Water absorbs IR very well. What do you think happens to the energy absorbed by water?
It can warm a wall but cant warm water? Why?”
CO2isLife says:
The basic physics of the molecule and LWIR. Just as visible light won’t warm glass, but will warm a black car. You can test this yourself. Simply shine an LWIR lamp with a 13 to 18 micron filter at water. Those wavelenghts don’t penetrate water, and will cause cooling surface evaporation. Solids will warm, but solids don’t evaporate.

CO2,
“Just as visible light wont warm glass, but will warm a black car. You can test this yourself.
Visible light won’t warm glass because glass is transparent to these wavelengths. Liquid water is NOT transparent to mid IR, is it?
When IR encounters water it has 3 choices
1. reflect – not much at normal incidence
2. Pass thru -No, not transparent
3. Absorb – Yes, by process of elimination
Once absorbed it heats. Water, especially if mixed like ocean, conducts surface heat below.
‘Simply shine an LWIR lamp with a 13 to 18 micron filter at water. Those wavelenghts dont penetrate water, and will cause cooling surface evaporation. Solids will warm, but solids dont evaporate.”
I have tried this with a ceramic heat lamp pointed down at cup of water. It heats the water quite well. Try it!
In the real ocean, most of the time it is NET cooling by emitting LWIR-but much less than otherwise because of DWLW from atm GHG.
CO2isLife
YOU: “CO2isLife: I think that goes without saying. That is the GHG effect, however, energy is radiated and diffused in a 360 degree sphere, so only a fraction goes back to earth”
Not sure where you pulled this nonfact from. Scientists measure, on a daily basis, DWIR in many locations. It is not a fraction, it is almost equal to what the Earth surface emits.
https://www.esrl.noaa.gov/gmd/webdata/tmp/surfrad_5b15e4da5ea46.png
Wet area in summer
https://www.esrl.noaa.gov/gmd/webdata/tmp/surfrad_5b15e5025cb2f.png
Dry area in summer
You can see the DWIR is significant not some the fraction would be quite large.
CO2isLife
YOU: “CO2isLife says:

Did you just make that up? First water is opaque to nearly all IR.
https://tinyurl.com/y8d5hxx8
Also you are just wrong.

IR water heaters are commercially available.
Why not do some actual research and support your conclusions with actual factual information. It seems you just made up that point without even trying to find evidence to support your statements.
Normal Says: Actual science shows your understanding is not correct. CO2 absorbs about 100% of the IR at the 15 micron range while water vapor absorbs around 50% even with its high concentration. If no CO2 were present you would have considerable IR leaving the Earths surface through space at this wavelength.
You can verify my claims multiple ways:
1) Go to MODTRAN and set the view to looking down from 0.1km and alter CO2 up to 800 ppm and measure the difference in W/M^2. Then alter the H20.
2) Go to Spectralcal and go to the gas cell and change the length to 1m. You will see H2O absorbs all the IR. What I imagine your graphic is showing is the result of a 10cm gas cell.
CO2isLife: I think you’re afraid to submit your work to a peer reviewed journal.
Sadly, nothing I write would ever pass the corrupt peer review process.
Actually, what you write would not even be handed over to the reviewers by the editorial staff of any serious scientific journal.
No need to waste their time, the piece of junk is quite apparent.
But sadly, your physics is wrong. BADLY wrong.
This is the worst:
The blackbody temperature of 13 to 18 LWIR is -80C.
Radiation does not have a temperature.
Do you understand the basics of the GHG effect? CO2 thermalizes 13 to 18 micron LWIR. When it thermalizes those wavelengths its signature is that of a blackbody of temperature -80 degree C. You can check that yourself at SpectralCalc. CO2 however doesn’t absorb the entire spectrum so it isn’t a true blackbody, so the energy is even less than calculated.
If I am wrong, and MODTRAN and Spectral Calc are wrong, please provide a correction. If thermalizing 13 to 18 micron LWIR doesn’t have a temperature, how then are we tying CO2 to increasing temperatures? Why does the outgoing spectrum show 13 to 18 micron having a temperature of -80 degree C? Check out MODTRAN, that is why they overlay the black body graphs.
CO2isLife
I am not sure what you are talking about.
What part of the SpectralCalc gives you this information?
http://www.spectralcalc.com/spectral_browser/db_intensity.php
Why not consider what CO2 emits. That is based upon its emissivity. Its effective emissivity does depend on water vapor content, as you correctly pointed out, that they overlap. The amount of IR CO2 will emit is based upon its emissivity and temperature. Its emissivity increases as concentration increases.
This could be of help.

Here is the link to SpecrtalCal BlackBody Calculator. We know that CO2 thermalizes 13 to 18 micron LWIR with a peak of 15 microns. Simply plug in the numbers. You will see, a blackbody of temperature -80C has a peak of 15 microns. The hotter an object gets, the shorter the wavelength peak becomes. LWIR is very very very low energy radiation, especially when compared to blue light that warms the oceans.
http://www.spectralcalc.com/blackbody_calculator/blackbody.php
CO2isLife says:
You will see, a blackbody of temperature -80C has a peak of 15 microns.
That’s a function of the BB’s temperature, not of the radiation.
In fact, a BB emits radiation of ALL frequencies. Do you know that?
This error, repeated lots of places, is in the top 5 among the denier set.
CO@,
Try plotting vs wavenumber. Note that CO2 is @ 670 ish. What Temp makes 670 the peak?
CO2: radiation doesn’t have a temperature.
If you disagree, give me the formula for the temperature of radiation as a function of its frequency.
You really need to examine the science behind those assumptions.

Hey ren,
Just wondering when you were planning to mention that the Arctic Oscillation is in the middle of its longest run of positive days in over a decade?
Alas, I suspect you will rate its ultimate switch into the negatives as more newsworthy, a switch that happens on average about 20 times each year.
I am going to say thus far the trends of late are down (ocean and land)which is significant for me, because I said late 2017 and 2018 would be transitional.
Does it mean I am correct no ,because temperatures are still high and the trend has just started.
That said , I think the magnitude of the drop (if it happens) is more important then the duration. I think for instance a drop of .5c in a year or so would be more meaningful then say 10 years of steady temperatures or a .5c drop over that time period.
I think the test is on and it is the whole globe that matters. That said certain areas of the globe have a big impact on the overall climate. One of those areas being the North Atlantic.
Time will tell and an increase in major volcanic activity is part of my scenario. So if cooling comes because of a major volcanic eruption if that should happen,I have said that contributes to cooling associated with prolonged periods of solar activity.
Salvatore, it’s been cooling since 2002. Why is anyone still arguing about it?

Maybe you will be correct ,maybe I will we will see.
Salvatore, you’ve been saying for years that ‘the test is on.’
Then, when proven wrong, you learn nothing and say it again.
You have zero credibility left.
The difference is this time the two solar qualifiers are in.
I can’t say like before I was wrong because my solar forecast was wrong.
That is the difference.,
You’ve said that before, too Salvatore.
And were wrong.
You never learn.

Well I am encouraged with year 2018 thus far. I will leave it at that.
Still the same problem as always, Salvatore — you look at just a few months of data, which is all due to natural variations, and ignore the big picture of the long-term trends.
You’re never going to learn.
David I am very interested.
What natural variations do you believe are so strong to cause these short term temperatures reversals?
What your saying is CO2 (AGW) drives the climate and yet at times it does not.
Salvatore,
Yet again you falsely claim that we claim that “CO2 is the only driver of the climate”. The rise in CO2 is very slowly raising the baseline. All the variation from other effects swamp this rise over any short time interval. One such short term effect is due to changes in ocean and atmospheric circulation, and that is basically what drives the ENSO variation.
Why do you keep insisting that we claim CO2 is the only driver, despite having been corrected countless times?
Answer: Because without that fictitious stance to argue against you argument dies.
The rise in co2 is slowly raising the baseline you say.
Fair enough.
Let’s see if it continues.
Salvatore,
And of course we would measure that using at least decadal averages, not by creaming ourselves over the daily ups and downs of sea surface temperatures.
IT
“What would be, according to you, the time of residence t of energy in a system ?”
Eli’s blue plate started at 0 K. Let’s say it received sunlight for only 10 minutes. A person could calculate how much total energy, in joules, had been absorbed during that time period.
After the 10 minutes is up and the sun is removed, you could then measure how long It takes before the plate is again at 0 K.
Couldn’t you use those two figures and come up with an average residence time for each joule?
******
What happens on a microscopic scale inside the plate doesn’t matter because we know, regardless of what form it takes, energy is conserved.
*******
If you did a similar “10 minute test”. using plates of varying widths and materials, you would find they had different residence times. For example, a 2 meter thick ceramic plate would take longer to cool to 0 C. than a 1 meter thick plate.
The two plates would have absorbed the same amount of energy, but residence time of energy entering the thicker plate would be greater.
No need for sorry, If you want to discredit yourself as scientist you can keep arguing that every set of numbers is a trend and every uptick and downtick of the noise in a system is a trend, and the numbers you picked is a trend, and blah blah blah forever.
eben…”If you want to discredit yourself as scientist you can keep arguing that every set of numbers is a trend…”
Or you can use inference. You can number-crunch a trend totally out of context then infer it represents anthropogenic warming, when in fact it’s due to natural forces like ENSO and/or volcanic aerosols.
Please explain how ENSO cycles with a period of a few years can cause a rising trend of 0.13C per decade over almost 40 years.
Please explain how 80 years period of the multi decade ocean oscillation evens out in a 40 year old satellite record ???

A humourist.
NOAA strips over 75% of the available data then applies less than 25% to a climate model where it is interpolated and homogenized to produce SYNTHESIZED data.
Then they reduce confidence levels to as low as required to move certain years into a ‘probable’ hottest year ever.
You call that precise?? I call it a sledgehammer approach featuring scientific misconduct.
There are signs they may be moving back to the science mainstream after the Trump admin intervened.

If it was bs you might have a point. However, when NOAA confirms it on their own site I’d venture a guess it is true.
NOAA doesn’t confirm that they deleted any station data on their website.
That’s a wrong-headed interpretation you make based on something you read on a blog.
You continue to lie. People continue to point that out.
It is not only BS, it is a lie, and Robertson perfectly knows that.
He refers to an old NOAA web page dated 2011 where they explain
– that a great number of stations (4,500) were removed from the inventory because of their lack of accessibility
but also
– that at the same time, a greater number of stations came new into the inventory.

My lady Rose pointed it out often enough: Robertson is an ignorant, pretentious boaster, and is an expert of nothing.
BTW, global temperatures clearly follow ocean cycles. Anyone want to take a stab at how CO2 and LWIR between 13 and 18 microns can cause El Ninos and La Ninas? How can CO2 cause such variability in temperatures? How can CO2 cause such temperature differentials between land, ocean, N and S Hemispheres? All share 407 ppm CO2, yet they all show wildly different warming trends.
As we keep saying (and as you keep ignoring), these large spatial and temporal variations are superimposed on a slowly rising baseline temperature. Why is that so difficult to understand?

The idea is not hare to understand. They just don’t want to. They are on a sacred mission.
Perhaps ‘sacred’ should be interpreted as ‘oil-funded’.
Bobdesbond
It is a possibility but I cannot imagine any oil company paying out money to Gordon Robertson for his posts.
Nevertheless, you have to wonder how so many mature-age deniers such as Gordon and Robert Holmes (1000frolly) are suddenly able to exist without income by returning to university and earning a degree. And most of these degree seem to have a connection to the use of fossil fuels. (Coal use in the case of Robert Holmes).
It is not CO2 that raises the global temperature. The butterfly chart shows the cause and gradual change.
https://solarscience.msfc.nasa.gov/images/bfly.gif
So according to that chart and your theory, the 70s should have been colder than the 60s. And the 2000s should have been colder than the 1980s. Is that right?
This shows that the oceans could accumulate heat for about 70 years.
Really? Would you point out where on your graph I should look for a reference to ocean heat content.
For example, in this passage.
https://solarscience.msfc.nasa.gov/images/Cycle22Cycle23Cycle24big.gif
Your link is not a ‘passage’. It is an IMAGE.
And again, where in that image should I look to find a reference to ocean heat content?
If you did not notice, the volume of sea ice in Arctic is the highest in five years.
http://ocean.dmi.dk/arctic/icethickness/images/FullSize_CICE_combine_thick_SM_EN_20180602.png
And the EXTENT is the 2nd lowest in 5 years.
Seriously – these year by year comparisons are meaningless.
The state of the sea ice is determined by its extent, thickness and volume
The ice cover in the Arctic grows throughout the winter, before peaking in March. Melting picks up pace during the spring as the sun gets stronger, and in September the extent of the ice cover is typically only around one third of its winter maximum.
Differences may occur in terms of the position of the edge of the ice in the two maps, Extent of the sea ice and Thickness and volume of the sea ice, as the model calculations do not always correspond exactly to the satellite sensors registration of the extent of the ice.
Ice concentrations are based on satellite data and are from the Ocean and Sea Ice Satellite Application Facility project (OSISAF).
The thickness of the ice shown is calculated by means of the HYCOM-CICE model of sea ice at DMI. The model calculates various oceanographic values, including sea ice, in a grid with cells of 10 x 10 square km. The model is driven by meteorological data from ECMWF (European Centre for Medium-Range Weather Forecasts). In each grid cell the ice is classified into 5 thickness categories, with thickness, concentration, movement and heat balance of the ice being calculated for each category. The map of the ice thickness shows the mean thickness of ice in each grid cell.
The graph on the right shows the annual variation of the volume of the sea ice in the Northern Hemisphere, excluding the Baltic Sea and the Pacific. The volume of the ice is calculated on the basis of the ice thicknesses from the HYCOM-CICE model. In each grid cell the volume is calculated as thickness multiplied with concentration and with area, with contributions from all grid cells to the total volume. The grey band around the climatologic mean value corresponds to plus/minus one standard deviation based on the 10-year average 2004-2013.
http://polarportal.dk/en/sea-ice-and-icebergs/sea-ice-thickness-and-volume/
The trend in the volume of sea ice in the Arctic has been reversed since 2012.
http://psc.apl.uw.edu/wordpress/wp-content/uploads/schweiger/ice_volume/BPIOMASIceVolumeAprSepCurrent.png
There is no such thing as a 5 year trend. Any attempt to find such a trend is hidden by random variation.
Don’t you see that what you write perfectly contradicts what you show?
I see that the volume of sea ice has never dropped more than in 2012.
I am sorry, probably in 1981 the volume dropped more.
“I see that the volume of sea ice has never dropped more than in 2012.”
Really? That’s what you believe your graph shows? When I look at your graph, I see a very slight drop from 2011 to 2012 in September ice, and and equally slight rise in April ice. I see much bigger drops in September ice in 1981, 1993, 1995, 1998, 2002, 2007, 2010, 2015 and 2016, and comparable drops in 1980, 1984, 1987, 1990, 1997, 1999, 2003 and 2005. Not that this is in any way significant, but it illustrates your inability to read a simple graph. Either that, or you are pretty poor at describing what you actually mean.
And yes, that’s right, few a few years Arctic sea ice had an anomalous run and fell below the trend line. It is only to be expected that in ensuing years it would return to the trend.
You guys really enjoy cherry picking your start points of a time series don’t you.
Ren back in 1986: “We’ve had 5 years of growing ice, so the earth must be heading into an ice age.”
… “FOR” a few years …
At the moment there is a clear drop in the temperature of the Atlantic. The temperature of the oceans soothes temperatures in the winter. As everyone knows, dry air does not keep the temperature in winter.
http://cr.acg.maine.edu/wx_frames/gfs/ds/gfs_world-ced2_sstanom_1-day.png
Still wondering when you intend to mention the Arctic oscillation again??
The temperature of the entire Atlantic has fallen, not only in the North Atlantic.
You didn’t answer my question.
The periods dominated by any single form of atmospheric circulation have alternated with a roughly 30-year period for the last 100 years. These periods were named “Circulation epochs”. These may be pooled into two principal groups: meridional (C) and combined “latitudinal” epochs (W + E): (W + E) = – (C)
Meridional (C) circulation dominated in 1890-1920 and 1950-1980. The combined, “zonal” (W+E) circulation epochs dominated in 1920-1950 and 1980-1990. Current “latitudinal”(WE) epoch of 1970-1990s is not completed yet, but it is coming into its final stage, and so the “meridional” epoch (C-circulation) is now in its initial stage. (It will be useful for the reader to note here the relation that shows that the “transition” from C to W-E is continuous, and the equation balances to 100%, in the form of a simple graphic without any other variables included).
http://www.fao.org/docrep/005/y2787e/y2787e03.htm
The recurrence of each circulation form (W, E, or C) during the year is expressed in days. Total annual duration of the three circulation forms sums therefore to 365 (or 366 in a leap year). The index is defined by the number of days with the dominant form of atmospheric circulation. It is more conveniently expressed as an anomaly (actual data minus the long-term average). The sum of anomalies can be displayed in a chart of the so-called integral curve of the atmospheric circulation. The annual sum of the occurrence of all circulation anomalies is equal to zero: (C) +(W) + (E) = 0.
“Current latitudinal(WE) epoch of 1970-1990s is not completed yet”
HUH??
Good question. ren knows how to cut-and-paste, but that’s about it.
ren says:

http://cr.acg.maine.edu/wx_frames/gfs/ds/gfs_world-ced2_sstanom_1-day.png
YET AGAIN, ren tries to claim a temperature change based on just one day’s worth of data.
The closer you look into ren’s links, the less believable they always are.
A strong eruptive phase (paroxysm) occurred at the volcano yesterday (Sun 3 June). Lasting for about 16-17 hours until the evening, it generated ash clouds reaching up to 10 km, which drifted into westerly directions for more than 40 km, lava flows descending on the flanks, heavy ash fall in nearby areas and secondary mud flows triggered by strong rainfall.
https://www.volcanodiscovery.com/fuego/news.html
How is “Arctic” defined geographically in the measurement?
The map, animation and graph illustrate the sea ice thickness in the Northern Hemisphere, excluding the Baltic Sea and the Pacific. The data is based on DMIs model calculations.
http://polarportal.dk/en/sea-ice-and-icebergs/sea-ice-thickness-and-volume/#c23717
Was ren right is assuming you were referring to his graphs, or were you referring to something from further back in the thread?
… “in” assuming …
If the global temperature trend up ends so does AGW theory.
Not much more to say.
But not using your concept of a trend.
Define “ends.”
I might add it is NOT how long the down turn in the temperature trend may be if it happens but rather the magnitude of the down turn.
So a 3 degree drop for a month, followed by an immediate return to the upward trend would demolish AGW theory, eh?
It’s the magnitude that maters?!
https://co2islife.wordpress.com/2018/06/03/the-most-powerful-evidence-climate-scientists-have-of-global-warming-rules-out-co2-as-the-cause/
So true. Another basic premise debunked.
ANOTHER FALLACY OF AGW THEORY.
Then we must not forget the basic premises this theory has been made up on all have not come to be such as the lower tropospheric hot spot ,among so many others.
Any other theory that had this much trouble with it’s basic premises would have been rejected by now.
So you believe journalists over scientists. Interesting.
Salvatore, do you think that gaseous CO2 doesn’t absorb infrared radiation, or do you think the Earth doesn’t emit any?
David,
“Salvatore, do you think that gaseous CO2 doesn’t absorb infrared radiation, or do you think the Earth doesn’t emit any?”
There is very good evidence that it does, but this doesn’t tell us how much warming, or if the net anthropogenic influence is actually even warming. We don’t know.
https://www.tropicaltidbits.com/analysis/ocean/
https://www.tropicaltidbits.com/analysis/ocean/global.png
The temperatures on one particular day say nothing about warming or cooling.
Right?
ren says:

The trend in the volume of sea ice in the Arctic has been reversed since 2012.
This, ren, is certainly wrong. I don’t have the ice volume data at hand, but I can tell you that ice volume behavior has been all the time similar to that of the pack ice area.
Here you see a chart showing, from 1979 till 2018, both extent and area in anomalies wrt 1981-2010:
http://4GP.ME/bbtc/1528120008724/001.jpg
The chart shows data originating from
ftp://sidads.colorado.edu/DATASETS/NOAA/G02135/north/monthly/data/
I can now directly download that data into Excel, instead of asking my friend to run his software :-))
Linear trends in Mkm2 / decade:
1. 1979-2018
– extent: -0.055
– area: -0.022
2. 2012-2018
– extent: -0.073
– area: -0.068
Since 2012, the pack ice declines even quicker than the extent.
Nothing dramatic but it is as it is.
From the data http://ocean.dmi.dk/arctic/icethickness/txt/IceVol.txt I picked up the highest and the lowest ice volume of each year and from the highest value I subtracted the lowest value to get the total amount of melted ice of each year. The result is following:
2003 2.24e+13
2004 1.90
2005 1.99
2006 1.86
2007 2.01
2008 2.00
2009 1.84
2010 1.98
2011 1.91
2012 1.90
2013 1,79
2014 1.78
2015 1.95
2016 1.82
2017 1.75
There is a clear trend of diminishing the amount of melted ice i.e. diminishing of the amount of heat available in the arctic region. Someone can maybe find whether this is due to the air temperature during the melting period or due to the SST of the arctic sea.
binny…”This, ren, is certainly wrong. I dont have the ice volume data at hand, but I can tell you that ice volume behavior has been all the time similar to that of the pack ice area”.
Oh, great, you don’t have the evidence but ren is wrong. Just like the fudged Excel graphs you put out showing UAH and NOAA very close.

These people are fighting a losing game.
They certainly named that blog appropriately – it certainly is deplorable.
Ad hominin attack. Not addressing the issue, but rather attacking the messenger. Often occurs when the attacker is in a weak position on content.
Really? Well perhaps you’d like to start by explaining how their graph shows that “The coverage of thick ice has nearly doubled over the past ten years,”
Heller is, as ever, trying to confuse. An increase in SIE compared to 12 months ago is not an indication of sea ice recovery.
When are you people ever going to learn???
David, are you deliberately replying to the wrong person to trigger a response?
inquirer…”Ad hominin attack. Not addressing the issue, but rather attacking the messenger. Often occurs when the attacker is in a weak position on content”.
Familiar position for bob/des and the rest of the alrmists here.
Salvatore: didn’t you see that Heller alias Goddard did not publish anything else than the DMI chart proposed by ren?
The volume of sea ice in the Arctic is more dependent on the temperature than the ice extent.

ren, exactly how does that graph prove what you’re claiming?
ren, I made two charts for you out of Colorado’s sea ice data.

Unfortunately, Piomas volume data does not seem to be available in txt or csv format.
Hey ren – your Arctic Oscillation just went negative after an 11 year high of 52 days in the positive. Are you planning to shout it out for all the world to hear?
It is better to look at the anomalies of the geopotential height in the winter above the 65th parallel.
https://pics.tinypic.pl/i/00966/qvpg9mtnqax7.png
Better?? I guess whenever you make a claim that turns out to be nonsense, it is better to switch to another one to save your butt.
I was looking at the May edition of Roy Spencer’s monthly anmomaly map; it isn’t there yet.
But again I looked at
https://www.nsstc.uah.edu/climate/2018/april2018/042018_tlt_update_bar.png
and see in my Excel data that indeed the last negative UAH anomaly for the Globe is dated by March 2012.
Salvatore please! Do something to cool the planet!
And the last negative UAH anomaly outside a La Nina (or the 5 month lag period after a La Nina) was in 2004.
My question is where is all the warming?
Aren’t you an unconditional fan of UAH?
Warming trend in the UAH6.0 record since May 2009 (ten years):
0.319 ± 0.059 °C / decade.
Is a trend of over 3 degrees per century enough for you?
You are foolishly thinking what has happened in the past is going to continue into the future (easy to go with trends) and are dismissing all other factors which can cause this not to continue.
My studies indicate that year 2018 is the first year where solar conditions (duration of time ,degree of magnitude change) are sufficient enough to put an end to the upward bias in global temperatures and will at a minimum put an end to the rise but more then likely promote cooling.
My same studies led me to believe solar through the end of year 2005 should have caused warming, and there after a halt but with lag times of 10+ years.
It takes very low solar conditions in regards to duration of time and degree of magnitude change to impact the climate in a significant way. That is why the solar signal is so obscure.
In addition the weakening Geo Magnetic Field weakening is going to enhance given solar effects.
That aside we are going to find out starting with this year and moving forward from here.
Prolonged Very Low Solar should result in overall surface oceanic cooling and a slightly higher albedo and if true will equate to cooler global temperatures.
Nature has now created the perfect test which is increasing levels of CO2 versus very low prolonged solar activity.
All of the above my sincere opinions right or wrong.
Salvatore Del Prete says:

Here are two charts comparing SSN with temperatures.
One for 1979-2018 with a 10 year lag on SSN:

and one for 1880-2018 with a 15 year lag on SSN:
http://4gp.me/bbtc/1528153004382/001.jpg
So you see exactly the effect of SSN (x – 10) or (x – 15) on the temperatures in year x.
If this satisfies your theory, then all is best for you!
Over how many centuries?
Let us presume 20 centuries. More you say?
The 3 degrees per century would have the temperature 2000 years ago 60degrees cooler than today.
Or are you going to change the parameters to suit yourself?
Lewis, you should know better. Much better.
When did man’s influence on the climate come to full fruition?
What factors are dominant today.
Jesus what a nonsense.
UAH’s trend for 1979-2018 is 0.13 C / decade.
Thus according to your superintelligent comparison, ‘the 1.3 degrees per century would have the temperature 2000 years ago 26 degrees cooler than today’.
Simply genial, Sir!
DA….”When did mans influence on the climate come to full fruition?”
No proof that man has ever influenced the climate.

Bond: clearly, I meant the amplitude of *temperature*
David, its funny, I recall you trying to jump all over Ed Berry for a similar silly mistake.
But that was ALL you had there!
Is there a link or quote you’re referring to? We’re not mind readers….
La Panglina, there are two solar requirements and the two requirements have not been present since the ending of the Dalton solar minimum around 1850 ad.
It looks like this year is the first time since then that the two solar requirements needed to cause global cooling are now coming into play.
According to my studies the solar period from 1850-2005 should have resulted in warming.
Only since 2005 did that start to turn and now if the low average value solar parameters within the sub solar activity in general can persist( which is happening in year 2018) will the solar requirement be present to result in a global cooling scenario.
This is what is taken with solar activity now , and with the expectations of the very low average solar parameters within the sub solar activity in general continuing , the result should be global cooling.
Note there are still two solar parameters that have yet to reached the low average value solar parameters I would like to see.
Those being the solar wind(350 km/sec or lower)/AP index(5 or lower), but they are coming down and could reach my criteria very soon but overall I say despite that the solar activity requirements are pretty much in for cooling.
At best global temperatures are going to stay steady, if not out right fall, which I think has already started.
This is not some long drawn out forecast. We will know from now thru the next few years.
If global temperatures should continue to rise I will be wrong if they fall I will be correct.
Only my opinions. Some agree, some do not.

Want to know why foolish skeptics are swallowing the 2012 sea ice volume bull from more devious skeptics?
Look at this cherry-pick.
http://psc.apl.uw.edu/wordpress/wp-content/uploads/schweiger/ice_volume/BPIOMASIceVolumeAnomalyCurrentV2.1.png
That’s the daily volume anomaly calculated against the the 1979 to 2017 daily average.
See the magnitude of the variation? It goes up and down a lot, so that even with a clear downward trend you can have peaks and troughs that are unbeaten for a few years.
The devious skeptics take advantage of ordinary random variation and make claims about changes in trend.
The foolish skeptics regurgitate that nonsense here.
More info from here:
http://psc.apl.washington.edu/research/projects/arctic-sea-ice-volume-anomaly/
Why go there? Because it is the source for everything on sea ice volume and thickness above – before idiots get their hands on it.
Of course, this is also how they make their claim of no warming since 1998.
Anyway, it’s up to us to take them to task when the data returns to the trend line. Even though we know they will conveniently pretend not to have made the claim. Or like Salvatore, pretend his claim was a conditional one instead on absolute.
And the same for the instrumental temperature record. How can anyone think warming has stopped as soon as there is a wiggle in the data, when it has been going on for two hundred years?
How can you think warming that has been going on for 200 years is due to CO2 production?
Because it looks like this:

Unreliable proxies with huge error bars early on. Misleading bold line that doesn’t even track the modern record very well.
“Not global how?”
Read the Y-axis label.
Global land is quite global.
‘bold line that doesn’t even track the modern record very well’
Considering that it doesnt incorporate any anthro aerosols, or ENSO variability, it is not expected to track perfectly, and yet, objectively, it does very well.
‘Unreliable proxies with huge error bars early on.’
As with any fit to data, as long as error bars are shown, we can judge the quality of the fit.
What proxies?
It was without proxies Bart, this one has proxies:
https://tinyurl.com/y95cmx6t
“Considering that it doesnt incorporate any anthro aerosols…”
Ah yes, the all-purpose fudge factor.
‘…this one has proxies:”
Guys, these are setups. The temperatures have been “adjusted” to improve the apparent fit to the CO2 data, as in USHCN data here:
https://pbs.twimg.com/media/CvcaBlAWgAESL4n.jpg
It’s nonsense. It is fooling themselves. They’ve already decided on the cause. Now, it’s just a game of nudging things until they vaguely fit the narrative to convince others.
It is really not hard at all to nudge things to produce a vague, seeming fit when you have such low frequency signals that happen to be more or less going in the same direction. What’s hard is matching both the low and the high frequency content. That’s been done. But, it isn’t the temperature to CO2 relationship that matches. It is the CO2 rate of change to temperature relationship that matches.
That relationship precludes significant sensitivity in the other direction, because it would create an unstabilizable, positive feedback loop. I am quite certain of it. It will come out eventually.
I see now, these aren’t even CO2 lines, but generic “GHG forcing” ones. So, you’ve got another layer of adjustable parameters to get a vague fit.
This is just awful. It’s pure confirmation bias.
Anthro aerosols
‘Ah yes, the all-purpose fudge factor.’
There is good evidence for global dimming and resultant forcing due to pollution.
https://agupubs.onlinelibrary.wiley.com/doi/epdf/10.1029/2008JD011470
But you will consider it unreliable.
‘It is really not hard at all to nudge things to produce a vague, seeming fit when you have such low frequency signals that happen to be more or less going in the same direction. Whats hard is matching both the low and the high frequency content.’
Not at alljust vaguely going in the same direction. Its a very good fit. You are simply in deep denial.
‘matching the high frequency content.’
What rot. Either the theory explains all variation or its wrong. You are pushing a false dichotomy.
There was no attempt to fit the high frequency content with slowly rising CO2, because known climate variability is not even considered here. You are looking at the trees and ignoring the forest (where have I heard that before?).
One note, CH4 does 50% of the CO2 forcing.
BEST used ln(CO2) as an “anthropogenic proxy” because a separate CH4 term did not improve the fit.
‘I am quite certain of it. It will come out eventually.’
Sounding a lot like Salvatore…
“There was no attempt to fit the high frequency content with slowly rising CO2, because known climate variability is not even considered here.”
That is why it is all the more remarkable when you find such an amazingly good fit. It’s the innocuous yet incontrovertible fingerprint that nails the culprit.
“BEST used ln(CO2) as an anthropogenic proxy because a separate CH4 term did not improve the fit.”
And, adjusted the temps until they had a vague resemblance.
You might as well cut off the temps at about 1910 – everything before that is just increasingly dodgy speculation. Ditto CO2 before 1958. These are simply data that have been coaxed into reflecting a pre-conceived paradigm.
“Sounding a lot like Salvatore”
He who laughs last, laughs the loudest. Salvatore is just getting impatient, and allowing himself to be boxed into a corner. The turning point will come when it comes.
BEST has a great method that can handle stations of varying quality. These results will be repeated again and again.
Ditto for CO2 before 1958.
I realize denial of all these results is a necessary part of your toolbox.
How many people do you think take part in this “fudging”?
‘You might as well cut off the temps at about 1910’
Ordinarily there is no justification for arbitrarily cutting off data.
Just take account of the larger errors going back.
‘And, adjusted the temps until they had a vague resemblance.’
Where does this notion come from?
All climate scientists are dodgy?
You seem to have changed your stance on how good the fit?
‘That is why it is all the more remarkable when you find such an amazingly good fit’
‘Its the innocuous yet incontrovertible fingerprint that nails the culprit.’
Again, some climate scientists may have behaved poorly.
This is work done by climate scientists (well.. mostly not).
Hence this work is dodgy?
Hasty generalization, I believe its called.
Nate:
“You seem to have changed your stance on how good the fit?”
I’m talking there about the fit between the temperature anomaly and the CO2 rate of change. It’s not just a vague resemblance in low frequency, low information, components, requiring innumerable “adjustments” to get there. It’s spot on across the entire spectrum.
“All climate scientists are dodgy?”
Some are. Some are extremely so. Others are so convinced they already know the answer that they believe cutting corners is OK. Others brave enough to go against the tide are hounded and disparaged into silence.
I think you guys just don’t realize how easy it is to fool yourself. I’ve seen it time and time again in my career – people get a computer result that I tell them looks dodgy, and they come up with reasons why no, that’s really how the system works. You wouldn’t believe some of the elaborate theories I’ve seen them come up with.
Then, they find the bug in the computer code that was causing the problem, and it’s “never mind.”
There really is nothing here that cannot be explained by happenstance, and a little nip and tuck here and there to present the data in the best possible light.
The problem is, scientists are supposed to challenge themselves by looking at things in the worst possible light.
Svante –
You can’t “handle” information that simply does not exist. At some point, your SNR is so low, it becomes rank speculation.
How many people take part in this “fudging”? Have you heard of the “Replication Crisis”? It is estimated that something on the order of 70% of research cannot be replicated. It’s not a joke. It’s not a conspiracy theory. It’s human nature. And, it’s especially rampant when people think they already know the answer they are looking for.
‘Some are. Some are extremely so. Others are so convinced they already know the answer that they believe cutting corners is OK. Others brave enough to go against the tide are hounded and disparaged into silence. I think you guys just dont realize how easy it is to fool yourself.”
Ok, you know that climate scientists, as a group, behave this way how?
Logical fallacies, such as your slothful induction applied here, are only meant for others, not you Mr. Spock?
The data is no good, its dodgy, its unreliable. The scientists lack all integrity, are sheepish and inept. No evidence needed.
It is an extremely desperate and lame-ass way to argue.
‘the fit between the temperature anomaly and the CO2 rate of change. It’s not just a vague resemblance in low frequency, low information, components, requiring innumerable “adjustments” to get there. It’s spot on across the entire spectrum.”
Bart, ask any of your stats savvy colleagues if this makes sense:
You have two sets of data x and y. You suspect they have a relationship y = Kx, with a constant K, for variations on all frequencies. Should you low-pass filter x so as remove a lot of its high frequency variation, but not similarly filter y? Does that make sense at all?
Would this perhaps be a good way to fool oneself?
” The temperatures have been “adjusted” to improve the apparent fit to the CO2 data, as in USHCN data here:”
What reputable source did this result come from?
You pay way too much attention to denialist blog alternative facts.
“Have you heard of the Replication Crisis? It is estimated that something on the order of 70% of research cannot be replicated. ”
As usual, Bart, your assertions cannot be replicated.
“According to a 2016 poll of 1,500 scientists reported in the journal Nature, 70% of them had failed to reproduce at least one other scientist’s experiment”, WP
Far different from ‘70% of research cannot be replicated’
The problem is real, but field-dependent. It is most prevalent in fields with living subjects: psychology, medicine.
Apparently the subset of papers with the worst record of replication is high-profile climate contrarian papers:
https://link.springer.com/article/10.1007/s00704-015-1597-5
“Ok, you know that climate scientists, as a group, behave this way how?”
Because people behave this way, and I’ve had many years of observation.
“The scientists lack all integrity, are sheepish and inept.”
This has been demonstrated to my satisfaction. Inept – I have seen analyses pertaining to this that just make me SMH. Sheepish – demonstrated by the ability of a small group at the top to get away with it. Integrity? We have the ClimateGate emails, which are incontrovertible to anyone with an objective perspective.
“Should you low-pass filter x so as remove a lot of its high frequency variation, but not similarly filter y?”
When y has already been filtered, it would make no sense to filter it again.
“What reputable source did this result come from?”
Prove it wrong.
“Apparently the subset of papers with the worst record of replication is high-profile climate contrarian papers:”
When a paper starts out with the 97% canard, you know it’s a total joke.
Should you low-pass filter x so as remove a lot of its high frequency variation, but not similarly filter y?
‘When y has already been filtered, it would make no sense to filter it again.’
Im assuming y is global temperature, x is co2 derivative, filtered at 24 months.
Temp has NOT already been filtered. Patently FALSE.
I remind you of your observation:
“people get a result that I tell them looks dodgy, and they come up with reasons why no, thats really how the system works. You wouldnt believe some of the elaborate theories Ive seen them come up with.”
Wrong.
There’s a match. A really, really good one. You should not spend your time trying to find excuses to ignore the match, but the reasons for it.
‘Theres a match. A really, really good one. ‘
Not how scientists talk when dealing with issues.
I can show you analysis in the freq domain that illustrates the issue very well.
Do you care to see, or are you all good?
Wrong again. Scientists do not sweep issues under the rug. When one sees something that cannot be explained, one seeks to explain it.
Show my your silly frequency domain argument if you like, and I will shoot it down. But, here’s a token for the clue bus: the frequency domain and the time domain are equivalent information. If you have a match in one, you have a match in the other. No rationalization you can come up with will change that.
‘The scientists lack all integrity, are sheepish and inept.
‘This has been demonstrated to my satisfaction. ‘
Some climate scientists (may have) behaved unethically (climatgate).
You have some experience with other humans.
Therefore climate scientists are unethical, and have various other failings?
You will happily make hasty generalizations such as this, when convenient.
Also, false dichotomies like AGW must explain all temp variation, even the natural stuff, or its wrong, are fine too.
Yet I thought you were our resident logician? Weird.
As my son used to say when he was upset with our rules: ‘you’re racist against teenagers!”
But it seems apropos here, you’re kind of racist against climate scientists. No other explanation makes sense.
Ok, note to self: there is no point in showing Bart data or results from climate scientists. He has decided, a-priori, its dodgy.
‘frequency domain and the time domain are equivalent information. If you have a match in one, you have a match in the other.
Of course they are they same. But what f-domain shows clearly is there is no pre-filtering of temp data.
The two data sets match well for high frequencies from 1/5 y^-1 to 1 y^-1, when a 12 mo filter is applied to both, and a scale factor of 1.8 is applied to CO2 deriv. There is matching peak at 1/4 y^-1
But the two sets then part ways for lower frequencies.
When a 24 mo. filter is applied only to co2 derivative, there is no longer a good match across the hf, nor at 1/4 y^-1 peak.
Spatial averages are the same as temporal averages when you have a traveling wave type of phenomenon. It’s like looking at widgets on a conveyor belt and counting them (spatial count) versus going on the other side of the factory wall and counting them as they emerge (temporal count). You’ll get the same count regardless over the same belt expanse.
The proof that this is such a phenomenon is the fact that the resolution matches. When you artificially introduce yet more filtering, you have different resolutions.
You’re chasing a parked car here, desperately searching for excuses to ignore what your eyes can see plainly. Just stop it.
There’s a match. If you don’t like my explanation, then find one for yourself. But, don’t use your lack of understanding as an excuse to turn a blind eye.
There is a match.
‘Looking for excuses’ You keep say this, but it couldnt be more inaccurate.
Ive been very consistent in raising this filtering objection from the getgo.
What you are doing to bend the data to your will is simply not justifiable nor kosher.
‘Spatial averages are the same as temporal averages when you have a traveling wave type of phenomenon.’
No, does not apply to temperature anomalies on Earth, which simply have seasonal average subtracted. Anomalies do not behave as a regular, periodic, traveling wave.
This is definitely in the category of ‘You wouldnt believe some of the elaborate theories Ive seen them come up with.’
If, by some fluke, you could publish this analysis, it would immediately become part of the replication crisis.
IOW, it could not be replicated with conventional science.
There are other papers that have looked at correlations between these two quantities, and none have applied this asymmetric filtering.
Let me pose this to you. If you were writing a Methods section of the paper, you would need to explain, in logical terms the steps you did in your analysis, and why you did them.
What would you write that could be understood and accepted by a peer reviewer? It can’t be just hand-waving. It would need agree with known physics and standard signal processing methods.
Spectra of Temp and CO2 derivative. x-axis frequency-, 60 corresponds to 1 y^-1 and 12 corresponds to 5 y^-1.

1-5 y asymmetric filter https://tinyurl.com/ybpcl653
Clearly the symmetric filter produces a decent fit across the 1-5 y time scales, while the asymmetric filter just cannot fit-there is too much hf in the unfiltered temp data–because it is not filtered.

This is just stupid, Nate. I don’t know what more I can tell you, or what good it will do. You’ve clenched your jaws on this red herring, and just will not let go.
Whatever. You’re wrong. Painfully and obviously so. But, you do you. Hasta la vista.
I mean, this statement is true, no matter your quibbles:
“The running average of the rate of change of CO2 at Mauna Loa on an annual basis is proportional to globally averaged temperature anomaly.”
That’s the relationship. If you want to say “well, there isn’t a direct proportionality with unaveraged CO2 rate of change”, well, so what? The relationship is still there.
You are just looking for excuses to keep your head in the sand. Just stop it. It’s just annoying.
“You’re wrong. Painfully and obviously so.”
If its so obvious, then you should be able explain it in simple terms without relying on other speculative notions about about how the Earth operates.
If you can’t refute what I’ve shown, point by point, and just call it stupid and annoying, that’s not very reassuring.
Facts and reality are annoying sometimes. I am just the purveyor of these.
If my critiques are so intolerable, then stop coming here and repeating the same bogus theory, again and again, as if it is a fact that cannot be questioned.
‘“The running average of the rate of change of CO2 at Mauna Loa on an annual basis is proportional to globally averaged temperature anomaly.”
That’s the relationship. If you want to say “well, there isn’t a direct proportionality with unaveraged CO2 rate of change”, well, so what? The relationship is still there.”
Well, I would agree to ‘the running average of the rate of change of CO2 at Mauna Loa on an annual basis is proportional to globally averaged running average of the temperature anomaly on an annual basis”
Look, if I knew nothing and I were looking to study the relationship between these two quantities, I would average CO2 over 12 mo because the annual cycle needs to be suppressed, then take the derivative.
Then naturally I would average the temperature over 12 mo. Then I would plot them together. We could scale one to match the other, and we would see this:
https://tinyurl.com/y7ndx3od
What you see is a strong correlation for high frequencies, as is well known. But thats it. There is no correlation for long term trends.
Now is where you come in looking for a certain relationship. So, by doing some manipulations, filter one series, but not the other purpose other than to artificially produce a relationship that you want, and surprise, you get what you want.
No. Not ok. Just not ok.
You are tossing out a relationship that explains everything with a minimum of rationalization based upon an arbitrary paradigm of how you think things should be.
It’s the same impulse that led church leaders to insist upon epicycles. Sure, the orbits looked like ellipses, but they should have been circles, therefore, they were. And, all those monks had labored so hard to fit the motion of the planets to those epicycles. Who was this upstart Galileo to come in and suggest he knew more than the experts?
“You are tossing out a relationship that explains everything with a minimum of rationalization”
How can you say such that? You have to introduce unproven speculations in order to rationalize your manipulations needed to achieve the desired ‘relationship’.
This is something you are constantly accusing the cheating climate scientists of doing!
Then you have toss out lots of legitimate data, and understanding of the carbon cycle, in order to rationalize your theory.
I’m just astounded that you don’t see why these things are problematic, and rationalizations themselves.
‘
‘Who was this upstart Galileo to come in and suggest he knew more than the experts?’
Pulleez.
< 0.001% of revolutionaries who said standard science is wrong, turned out to be correct.
I am saying standard science is wrong, therefore I must be correct.
Do you see the flaw in this logic?
The other 99.999% are promoting perpetual motion machines, a flat Earth, free energy from water, N rays, cold fusion, and relativity is all wrong.
“You have to introduce unproven speculations in order to rationalize your manipulations needed to achieve the desired relationship. “
No, the relationship exists all on its own. I have a hypothesis about how the relationship comes about, but the relationship stands on its own. The running average of the rate of change of CO2 at Mauna Loa on an annual basis is proportional to globally averaged temperature anomaly.
“Then you have toss out … understanding of the carbon cycle… “
Yes, those monks worked so hard on the epicycles, and you just tossed out all their work based on a mere observation.
“Do you see the flaw in this logic?”
Yes. Your fallacy here is: straw man.
Bart,
Your understanding of what epicycles were is off the mark.
Again, paradigm shifts are rare events.
Arguing that since you are proposing a paradigm shift, it is more likely, is quite illogical.
Back to the issue at hand.
Your argument is that low frequency and high frequencies in signals x and y have the same proportionality constant, and that is the only adjustable parameter needed.
But by introducing an asymmetric filter on x, you can SUPPRESS the high frequency variations in x, without suppressing those in y.
It is quite obvious that the filter changes the scale factor, and BTW, the width of peaks in a telling way:
https://tinyurl.com/y7fesb44
Therefore you have added a second adjustable parameter, that allows you adjust the high frequency proportionality constant until it matches the low frequency one.
Thus you get a manufactured relationship.
“Yes, those monks worked so hard on the epicycles, and you just tossed out all their work based on a mere observation.”
Monks and epicycles opposed Galileo = climate scientists and their data oppose Bart??
Logic fails,
Bad analogy? Guilt by association? General stupidity?
“But by introducing an asymmetric filter on x, you can SUPPRESS the high frequency variations in x, without suppressing those in y.”
Then, it is no longer the same signal.
Dont follow? Same signal with reduced hf variation.
You seem to be arguing that if you change something, it no longer is the same, and therefore it never was what it was in the first place.
I don’t know why you seem to think this is a profound insight, or really a point of any kind.
I have no idea what you are trying to say. The main issue is clear.
You are deluding yourself.
‘You seem to be arguing that if you change something, it no longer is the same, and therefore it never was what it was in the first place.’
No did not say anything like that, or mean that, weird.
How bout telling me which, of the things I did say, you disagree with, and why.
What’s the point? We’ll just go round and round again saying the same things, and you will keep denying the relationship you can see right in front of your eyes exists because you can change the signals, and suddenly, inexplicably, they’ve changed.
Oo-kay. Whatever. Life’s too short.
I agree we’re going round and round.
But look, its absolutely normal in science to expect that someone can rationally explain their methods, particularly when the main result depends entirely on those methods.
If you cannot do that, then your ideas can never be taken seriously.

Your fallacy is: argument from incredulity.
The argument seeks to categorize coordinated action by like-minded people as an rare phenomenon, when it is not rare at all.
‘Your fallacy is: argument from incredulity.
“The argument seeks to categorize coordinated action by like-minded people as an rare phenomenon, when it is not rare at all.”
Bart is saying, I think, that science conspiracy theories are often true?
Proof?
‘Massive motion’
.5 % of degree ~ 5km, diameter 10 km.
Is that a lot? Hard to say. Its over 10 y.
So max velocity is tiny, 30 microns/ s
Very tiny velocity gradient N-S.
Seems like tidal effects and coriolis forces must be must be much much larger.
It’s more like 74 meters differential motion. It’s massive, though, because the waters have to move, and it’s a whole lot of water.
Tides are different. They are largely longitudinal. This would be latitudinal, and the thermal gradients are much greater in that direction.
I wouldn’t bet a ton of cash on it, not enough to cause devastating financial pain if I were wrong at any rate. But, enough to cause some discomfort. I do think it is a distinct possibility.
The important point was that failing to see the 11 year cycle in temperature data is not dispositive as to the impact of solar variation on terrestrial temperatures. It could be the time constants are so long that an 11 year cycle gets sharply attenuated. Or, it could be that it modulates other cyclical phenomena and the impact appears at a different frequency, as I am suggesting here. Or, both.
We will just have to wait and see with more data and more study.
Arrrgh, got put in wrong place.
“Climate Change Has Run Its Course”
“Scientists who are genuinely worried about the potential for catastrophic climate change ought to be the most outraged at how the left politicized the issue and how the international policy community narrowed the range of acceptable responses. Treating climate change as a planet-scale problem that could be solved only by an international regulatory scheme transformed the issue into a political creed for committed believers. Causes that live by politics, die by politics.”
https://www.wsj.com/articles/climate-change-has-run-its-course-1528152876
I don’t think there were any scientists who were/are genuinely worried about the potential for catastrophic climate change.
I think there were millions of brainwashed children who were/are worried about the potential for catastrophic climate change. And there were too many adults, who worried endlessly and uselessly about it.
Any adult vaguely concerned, should have looked into the matter, instead merely been zombies.
Keywords: “I think”.
If worried (and you are sane) you do something.
Take for example, nuclear war, people built bomb shelters.
And climatic activists, fly the world in jets.
Private bomb shelters are not the optimal solution to the nuclear threat. Nuclear weapons have to be eliminated, or at least not proliferated, they are just too dangerous in the long run.
It’s a lot like the CO2 problem.
Nuclear weapons have kept relative peace for all the years since they were invented. They make the cost too high for would-be conquerors and put they, themselves, at risk.
Eliminating nuclear weapons would again make war acceptable as a means to an end. It would be horrific.
Assuming stable countries with rational leaders, and no mistakes. For hundreds of years?
Are you from North Korea?
Only one country has detonated a nuclear weapon in anger. And it is indeed an unstable one.
50 MILLION people died in WWII directly from war related causes. About 0.5% of those were from nuclear weapons. Industrial killing is no picnic, either.
It’s better when the only way one wins is by not playing the game.
Sane? ‘Take for example, nuclear war, people built bomb shelters.’
People building bomb shelters are failing to understand how nuclear war works.
‘Treating climate change as a planet-scale problem that could be solved only by an international regulatory scheme’
How else could we solve any global problem such as this?

It’s just Kabuki theater.
‘The place where vested interests inject the most $ into politics.

No, how much $$ is allowed to influence elections and politicians in the US is not rational, not desirable, its out of control, but SCOTUS has enabled it.
Damn that dastardly SCOTUS, standing up for freedom of association!
I guess your vested interests only act from the goodness of their hearts. Yeah, no. I’d prefer to maintain a check on that.
Bart,
I understand that people have different philosophies on government. One can have a POV that is values based, not fact-based.
Why should that correlate with judgement of fact-based science at all? It does for climate science.
Why do you and others seem to judge climate science, only after passing it through an ideological filter?
We don’t. We evaluate it on the basis of the evidence. And, the evidence is lacking.
Politicization has occurred on the other side. The proffered “cures” for the supposed disease are all focused on limiting individual freedom, and supporting political goals.
Some of the leading lights of the AGW movement were focused on global cooling back in the day (e.g., Dr. Stephen Schneider, R.I.P.) and turned on a dime when the meme went to catastrophic warming. The goal is always the same – to stampede the population into giving up its rights and privileges in the name of some phantom menace.
H.L. Mencken perhaps said it best:
“The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary.”
‘The whole aim of practical politics is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary.
I think he would explain Trumpism exactly this way, with its fear mongering about immigrants, brown people, disrespecting the flag, the evil press, the deep state, etc. He would be disgusted.
‘We dont. We evaluate it on the basis of the evidence. And, the evidence is lacking.’
Wow. You have never once considered evidence that I have shown you or described to you as credible, published or not. For you, it all has some inexplicable problem if it doesnt fit your narrative.
Your biases are quite clear. To do science you cannot operate that way.
‘The goal is always the same – to stampede the population into giving up its rights and privileges in the name of some phantom menace’
This POV is always hard to swallow. We can certainly debate the severity of the CO2 caused problems.
But fundamentally what ‘rights and privileges’ would you be losing if emissions are regulated?
Do you have a fundamental ‘right’ to dump sh*t in my yard? I’m sorry to tell you that you don’t.
Do you have a ‘privilege’ to send your sh*t downstream or downwind to the next town or state? Thankfully, more or less, society has decided NO on that one.
Do you have a ‘right’ to not have to pay the fees for your sewage treatment and disposal?
You do have the right to move somewhere that doesnt provide these services.
As I say to my teenagers, if you are living with other people, you don’t have the ‘right or privilege’ to create a mess in the space we all share and not clean it up.
jimc…”Treating climate change as a planet-scale problem that could be solved only by an international regulatory scheme transformed the issue into a political creed for committed believers”.
The nonsense began with a political game created by UK PM Margaret Thatcher. She could not deal with striking coal miners and she was advised to use her chemistry degree to baffle UN delegates into believing coal emissions could warm the planet. It was her way of getting rid of the coal miners by banning coal.
Due to her propaganda, the IPCC was formed by the UN in conjunction with the World Meteorological Association to investigate only the role humans have played in the warming. Even if the planet freezes over, the IPCC lacks the mandate to investigate.
Thatcher played a role in having John Houghton appointed the first UN co-chair and he, being a climate modeler, lead the IPCC into the sci-fi world of climate modeling.
This played right into the hands of the UN who had been seeking a mandate since the 1960s to form a world government with the power to tax member nations.
Gordon: Where did you get all this from regarding the miner’s strike and Margaret Thatcher?
As an example, you comment that ‘She could not deal with striking coal miners and she was advised to use her chemistry degree to baffle UN delegates into believing coal emissions could warm the planet. It was her way of getting rid of the coal miners by banning coal.’
This account brings back my recollections from that era – although I’m no historian and can’t vouch for all of the points made:
https://en.wikipedia.org/wiki/UK_miners'_strike_(1984%E2%80%9385)
The whole issue of fossil fuels potentially raising the temperature of the planet wasn’t even a blip on the horizon in the reports of English newspapers that time.
I find it hard to believe that ‘Due to her propaganda, the IPCC was formed by the UN in conjunction with the World Meteorological Association to investigate only the role humans have played in the warming’ – where is the historical evidence for this?
Carbon,
‘where is the historical evidence for this?’
In my experience, Gordon will not respond to your quite reasonable request.
Then in a few weeks, he will repeat the same BS, as if no one ever debunked it.
It works for him.
I see that both UAH and RSS data show a slower rate of warming in the mid troposphere as opposed to the lower troposphere, both globally as well as at the tropics. This is the opposite of what is expected with positive water vapour feedback.
When is this clearly debunked hypothesis, that climate alarmism so heavily depends on, officially going into the dust bin?
UAH and RSS data show cooling in the stratosphere, which is precisely what is predicted due to an increased greenhouse warming, and is not predicted by ANY other scenario.
The effect you are speaking of is supposed to happen as a result of warming from ANY cause. As there has definitely been warming, yes it’s absence needs to be explained, but it speaks nothing about the cause of the warming.
I look forward to your attempts to further revise the predictions of climate change.
You know nothing about ozone and temperature in the stratosphere.

Bobdesbond says, June 4, 2018 at 11:44 PM:
Uhm, no. It is “precisely what is predicted due to an increased greenhouse” cooling. Put more CO2 into the stratosphere and you get cooling. And that’s about it. What’s going on above the tropopause hasn’t got anything to do with what’s going on below the tropopause, where things are convectively governed rather than radiatively governed.
This “some mechanism is causing stratospheric cooling, therefore tropospheric warming is caused by the very same mechanism” argument is just so inanely stupid!
Yes, it is. Decreasing stratospheric ozone. Both mechanisms (-O3 and +CO2) are and have been contributing to the cooling.
Stratospheric ozone concentrations bottomed out in the early 90s, and have slightly risen since then. Bad luck with that one.
What’s going on above the tropopause hasn’t got anything to do with what’s going on below the tropopause, where things are convectively governed rather than radiatively governed.
You guys love your false dichotomies don’t you. It is not a case of “either/or” with regard to radiation and convection.
Bobdesbond says, June 5, 2018 at 4:07 AM:
You must suffer from a serious case of reading impairment. What did I write? “Both mechanisms (-O3 and +CO2) are and have been contributing to the cooling.” I also wrote, just a little bit higher up: “Put more CO2 into the stratosphere and you get cooling.”
So what is it? Are you being straight-out dishonest? Or just stupid?
But YOU’RE implicitly claiming it’s a matter of “both/and”! And so the onus is on YOU to SHOW that this is in fact the case, not just assert and assume it and expect everyone to immediately bow their heads in compliance.
Exactly WHY and HOW is evidence of some (whatever) mechanism causing stratospheric cooling somehow proof that this very same mechanism is therefore ALSO automatically causing tropospheric warming!? When you KNOW that 1) ‘cooling’ is not equal to ‘warming’, and that 2) the stratosphere does NOT operate in the same way as the troposphere, that their thermal structures are generated and maintained based on completely different principles …
“Stratospheric ozone concentrations bottomed out in the early 90s, and have slightly risen since then.”
Incorrect. This has only been true of the “ozone hole” at the South Pole. Elsewhere, there has been a steady decrease in stratospheric ozone.
Nope.

Both mechanisms (-O3 and +CO2) are and have been contributing to the cooling.
If that doesn’t claim that O3 concentrations have been falling, then yet again your English is very poor.
It seems deniers believe they are in a privileged position. Apparently they can make any BS claim they wish without evidence, then we have to provide all the evidence to prove you wrong. Is that how you believe science works?

Also vs height. Fig 3-2. There is a leg to stand on.
Seems to be a difference of opinion on the lower strat, but not upper strat.
All the same primary source.
Ie. you cite 6 sources, impressive, but they all refer to the same research paper.
You are flailing.

No they don’t!
This site http://images.remss.com/msu/msu_time_series.html
Click on channel TLS (temp lower stratosphere) No cooling since 1994!
RSS shows a continuum of trends, from strong warming in the troposphere, to strong cooling in upper stratosphere. In the lower stratosphere you find flat.
This is exactly what is expected, given that each layer has contributions from those above and below it.
I don’t think your premise is true. Why should increased WV response to surface warming specifically show up in the mid-troposphere?
I think you are alluding to the ‘hot spot” argument. If so, that is an issue with lapse rate feedback, not a WV feedback.
The ‘hot spot’ is specifically supposed to be caused by an increase in tropospheric WV, isn’t it? Warmer surface => more vigorous evaporation => strengthened water cycle => more latent heat released in the tropospheric column => reduced lapse rate; the mid and upper levels of the troposphere warmer RELATIVE TO the surface.
exactly correct and there is no hot spot.
NO – never warmer than the surface directly below. Not in the troposphere.
Bobdesbond says, June 5, 2018 at 5:52 AM:
Say what!?
No one’s saying the mid to upper troposphere is supposed to be actually warmer than the surface. Do you understand at all what that red spot is meant to signify? It warms more over time THAN the surface. Because the lapse rate becomes ‘moister’, hence reduced. That’s not the same as saying the troposphere becomes warmER than the surface.
“the mid and upper levels of the troposphere warmer RELATIVE TO the surface.”
YOU said it.
Pretty sure Kristian meant more warmING relative to the surface.
K, here’s realclimate on the hotspot from 7 years ago.
“If the pictures are very similar despite the different forcings that implies that the pattern really has nothing to do with greenhouse gas changes, but is a more fundamental response to warming (however caused). Indeed, there is a clear physical reason why this is the case the increase in water vapour as surface air temperature rises causes a change in the moist-adiabatic lapse rate (the decrease of temperature with height) such that the surface to mid-tropospheric gradient decreases with increasing temperature (i.e. it warms faster aloft).”
As I understand it from reading elsewhere, the WVcontent of the whole troposphere is expected to increase, not a specific enhancement in the tropical mid-troposphere that by itself would cause warming. Indeed, the tropics themselves warm slower than the rest of the globe, owing to the more saturated air – logarithmic GHG effect means less warming where there is already a stronger GH effect.
Observations looking for the hot spot do not generally look for WV content as a marker. They are based on radiosonde temps (and even on wind shear).
A decreasing lapse-rate is the immediate cause of the purported hot spot. I’m not sure that this arises because of extra WV in the region. But I’d need to read up on it again to be sure.
And the hot spot is not an issue of AGW. It’s just an issue of GW whatever the cause, be it the sun, the CO2 or whatever, is irrelevant.
So all those morons fond of claiming eagerly both that “it’s the sun” and “there is no hot spot” are particularly hilarious.
Idiot tracker says, June 5, 2018 at 6:23 AM:
Idiot,
It’s not a claim. It’s an observational fact. The “CO2 did it” argument is the claim here.
But I guess to you this is, once again, just a bunch of “philosophical drivel”.
Well, here for once your drivel is rather wishful thinking..
Amusing too.
Kristian, the hotspot is a theorized result of enhanced warming in the tropical mid troposphere regardless of the source of warming. It’s not a unique signature of greenhouse warming.
And, it’s not there. Which should tell you what?
Hint: Do “they” really have any idea what they are talking about?

Empty trash talk.
Which should tell you what?
It would tell me that this modeled property of heat transport in the atmosphere is wrong.
The fact that people are saying ‘the hot spot isn’t there’ also tells me that they are ignorant of the matter or have a biased view.
The fact is that the jury is out on whether there is a hot spot or not, and shills pick the data or study they prefer to make the case they like.
Uncertainty gets shoved aside when the shills rush in.
If the uncertainty is that great, then dare I suggest that the science isn’t settled?
If the uncertainty is that great, then dare I suggest that the science isnt settled?
The hot spot thing is a detail, a small lapse rate related feedback effect, not at all a serious “uncertainty” about AGW. By no means does this “uncertainty” question the GHE and the warming potential of additional anthropic CO2.
The situation is quite similar to the rotundity of Earth. By no means does a lack of knowledge about the precise form of the geoid question this rotundity.
The fact is that science in general is of course never settled, yet a lot of specific scientific questions are quite settled for sure.
“Great uncertainty” about AGW is only in the amplitude of the expected effect because of complexity, in technical sense, so our inability to estimate seriously major more important feedback effects.
“By no means does this uncertainty question the GHE and the warming potential of additional anthropic CO2.”
What it does question is the absence of any conclusive evidence that additional CO2 from any source is warming the planet.
‘Great uncertainty’ about AGW is only in the amplitude of the expected effect…”
Which could be zero.
“…because of complexity, in technical sense, so our inability to estimate seriously major more important feedback effects.”
Effects which could be negative.
A seasoned professional knows from experience that one must resolve all loose threads, because that one nagging loose end can unravel the entire fabric.
“And the hot spot is not an issue of AGW.”
It is, because it is part of the understanding of how the system works. That it has not been observed suggests the understanding is lacking. “We don’t understand that, but trust us on this” is not a very convincing sales pitch.
There is nothing on sale, science doesn’t care whether laymen “buy” it or not.
Now I’m not sure much understanding is lacking in this respect but, yes, understanding is
certainly lacking in general and not only in climatology but in physics and
science in general and particularly in medical science and even in… aerodynamics. If it were not, scientists and engineers would not be at work anymore.
I find it highly amusing that deniers most likely readily “buy” medication or flight tickets and not AGW while on the other side of the fence green activists do rather the reverse. Though I not sure about the flight tickets.
We buy things that have been proven. The others do it based on feelz.
We buy things that have been proven. The others do it based on feels.
Same claim on the other side of the fence .
Hilarious.
There’s an objective difference. E.g., not accepting AGW as established fact is rational, given the paucity of confirmatory evidence. Not accepting GMO foods is ridiculous, in light of copious, unequivocal data demonstrating the advantages.
Nope.
Not accepting AGW is not more rational than rejecting (or accepting) GMO foods and biology, by the way, is at least as much complexity and uncertainty as is the climate system.
https://en.wikipedia.org/wiki/Complexity
Not accepting AGW is just a matter of physics and science illiteracy and ideological bias.
The only thing that remains to be questioned is CAGW
Nope. We are not driving CO2 concentration, so the “A” in “AGW alone is wrong. Then, there is no proof that the aggregate response of the climate system to increasing CO2 concentration is significant or even positive in the present climate state. The dependence is assuredly nonlinear, and we do not know the present tangent slope a.k.a. the sensitivity.
We are not driving CO2 concentration, so the “A” in “AGW alone is wrong.
This is as hilarious as denial of pregnancy…
It’s fun to watch.

Looking at the RSS data for TLT and TMT, your comparison is correct. However, the TMT data is contaminated by what is happening in the stratosphere (see TLS), which is a strong cooling trend. The TLT was originally intended to remove this cooling trend from the TMT to provide a correct measure of changing temperatures. Claiming that the TMT shows the opposite of the trend expected from theory ignores the problem of stratospheric contamination.
There’s another approach to removing that contamination, which is the TTT. You will notice from the RSS site that the TTT has a greater trend than the TLT. Thus, these data do not “debunk the hypothesis”, as you claim.
Ren, what matters are what the global temperatures will be doing as we move forward.
I believe that the surface temperature of the Atlantic will remain low.

Congratulations on cherry picking less than 4% of the world’s oceans with those two links. You do realise that there is ALWAYS some part of the ocean that is momentarily cooling, right? You just hop from one region to another, creating an illusion of cooling by only ever focusing on the cool ares. The same method used by that idiot non-scientist adapt 2030.
That’s all you have to say?
That was a lot more than you say in the vast majority of your comments. What criterion did it not satisfy to qualify as a meaningful response?
Ren good info. So since 1970 the world oceans have warmed .1c.
Global warming.
How the hell do you come to that conclusion?
That is what that data that Ren sent shows. It shows the deviation in ocean temp form 1971-2000 is +.1c
https://www.tropicaltidbits.com/analysis/ocean/
I like this source for ocean data the best.
Let me get this right. You believe that when an anomaly is given as +0.1 above the AVERAGE of 1971 to 2000 temperatures that this temperature is 0.1 degrees above the 1970 temperature??
Is your mathematical ability really THAT weak?
(Not to mention that you are cherry picking a single day.)
This was supposed to be in response to your previous post.
No. I believe the anomaly of +.1 c , is +.1c above the average ocean temperature from the period 1971-2000.
This graph shows how the average surface temperature of the worlds oceans has changed since 1880. This graph uses the 1971 to 2000 average as a baseline for depicting change. Choosing a different baseline period would not change the shape of the data over time. The shaded band shows the range of uncertainty in the data, based on the number of measurements collected and the precision of the methods used.
https://www.epa.gov/climate-indicators/climate-change-indicators-sea-surface-temperature
The temperature of the ocean has not changed since 1940.
They think once a trend is established it can’t change. That is the thinking.
ren’s nonsense continues and continues: on the graph accessible thru the link, the EPA shows an increasde of nearly 1C.
Even the ‘cool’ Japanese Met Agency shows a clear increase:
http://www.data.jma.go.jp/gmd/kaiyou/data/english/long_term_sst_global/global_rngmn_e.png
http://www.data.jma.go.jp/gmd/kaiyou/data/shindan/a_1/glb_warm/global.txt
It is clearly visible both in the chart and in the data that between 1940 and today, JMA’s Global SST has increased by 0.5 C.
That is a noticeable amount: more than the linear estimate for a whole century.
binny…”the EPA shows an increasde of nearly 1C”.
The EPA lead the cheaters like NOAA and GISS. Anything coming from the EPA is major bs.
Gordon, the JMO (Japanese) use their own ocean data set – which was why it was mentioned. Salvatore’s ‘estimate’ is not only mathematically appalling but debunked by any data set you care to mention – including UAH.
But the worst of Sal’s comment is that he compares one data point with another and talks as if it’s a trend.
It’s akin to noticing that one day in Summer and one in Winter happen to have the same temperature and concluding that Winter and Summer have the same average temperature.
If you were neutral and know anything about mathematical analysis you would join in on pointing out Sal’s error here. But you have to keep grinding the ax instead, eh?
Salvatore
Then why did you say it was 0.1C above 1970?
Your comment:
“So since 1970 the world oceans have warmed .1c.”
Because it’s so anti-AGW. Doesn’t mater that it is mathematically silly.
I made a mistake
Indeed. You once again could not find the “reply” tab.
Here is a great look at the power of wind. From Bloomberg “…Britain’s gone seven days with almost no wind generation and forecasts show the calm conditions persisting until the middle of the month.
The wind drought has pushed up day-ahead power prices to the highest levels for the time of year for at least a decade. …”.
…https://www.bloomberg.com/amp/news/articles/2018-06-05/wind-disappears-in-britain-leaving-turbines-at-a-standstill
Now that is interesting.
Without wind power the price of electricity goes up.
This means that wind power is cheaper than the alternatives.
entropic…” Without wind power the price of electricity goes up.
This means that wind power is cheaper than the alternatives.”
Typical of the obfuscated reasoning of climate alarmists and an example of why it’s so easy to defeat their propaganda and theories.
Then why don’t you actually defeat it, instead of merely boasting that you could.
A shame that consumers have to pay for the wind turbine infrastructure only to have to fall back on other resources and then have to pay for that too. Should have balanced their investment with some coal/oil or gas fired plants. More stable and less expensive.

I expect you will need to change the question in order to answer.
Hahahaha. Ren posts a satellite map of a weather system and Gordon doesn’t bother clicking on it but sounds off like ren has produced something crucial instead of the same old weird weather map without comment.
Ren’s posts are the climate blog version of haikus. You can ignore it or have a bit of fun.
But there’s no substantial argument there, Gordon. You goose.
Recall on an interesting post written on CarbonBrief by Zeke Hausfather (for sound skeptics only):
Why troposphere warming differs between models and satellite data
https://www.carbonbrief.org/study-why-troposphere-warming-differs-between-models-and-satellite-data
and from there to this article (Santer & alii, free version of their paper behind paywall):
Causes of differences in model and satellite tropospheric warming rates
https://tinyurl.com/yaxsa37p
binny…”Why troposphere warming differs between models and satellite data…”
More bs from an obfuscating alarmist. A gross generalization of satellite data acquisition versus climate models. There is no comparison to begin with since models are programmed with a fabricated warming effect for CO2 and they depend on a non-existent positive feedback to project a sci-fi catastrophic warming.
The author is an idiot. No mention of the scientific misconduct perpetrated by NOAA and GISS in which the fudge temperatures and declare record warming years by halving the required confidence level.
Here we have someone who believes averaging data increases the absolute error calling someone else an idiot.

Gordo, Speaking of idiots, I love it when you disrespect someone who has much more knowledge than you. Did you read the Santer et al. 2017 paper, or are you just pontificating based on Hausfather’s commentary? Have you figured out that the “satellite temperature” data you and the other denialist love to reference are based on models? Please do tell us which one of satellite records you prefer and an exact reason for your choice. There are four groups that have analyzed the tropics, including the U. Washington team.
For example, the UAH LT tropical trend is 0.12 K/decade while the RSS TLT trend is 0.15 K/decade. Or, do you prefer the TMT and, if so, tell us why.

CO2isLife
I want to bring you post down here as it is easier for me to see a reply than scroll all the way up.
YOU: “Normal Says: Actual science shows your understanding is not correct. CO2 absorbs about 100% of the IR at the 15 micron range while water vapor absorbs around 50% even with its high concentration. If no CO2 were present you would have considerable IR leaving the Earths surface through space at this wavelength.
You can verify my claims multiple ways:
1) Go to MODTRAN and set the view to looking down from 0.1km and alter CO2 up to 800 ppm and measure the difference in W/M^2. Then alter the H20.
2) Go to Spectralcal and go to the gas cell and change the length to 1m. You will see H2O absorbs all the IR. What I imagine your graphic is showing is the result of a 10cm gas cell.”
You are still wrong. I did as you said and you it is just wrong.
Here I will post the graphs:
Water Vapor through 1 Meter at surface atmospheric pressure. Band between 14 and 16 microns (displays only in wavenumber).
http://www.spectralcalc.com/calc/plots/guest851722317.png
Not even close to absorbing all the available IR in this band. I have no clue what you did to get different results.
Now 1 meter through Carbon Dioxide same band same conditions.
Now you see that in this band nearly all the IR is absorbed.
http://www.spectralcalc.com/calc/plots/guest68396004.png
So you need to tell me what you are doing to get your results.

Thanks for the advice. Is it worth the effort? The plots I made show that through 1 meter CO2 absorbs nearly 100% (transmits zero) at the 15 micron wavelength but water vapor transmits considerable amount of energy.
norman…”Thanks for the advice. Is it worth the effort? The plots I made show that through 1 meter CO2 absorbs nearly 100% (transmits zero) at the 15 micron wavelength…”
Good grief, Norman, the two graphs floating around here show CO2 absorbing about 5% at 15 microns. That’s about 5% of nothing.

Less melting because less ice to start with at the beginning of each melt season?
Your conclusion is correct: summer temperatures are more stable.
Summer temps are more stable because of the presence of sea ice.

Ren, it is looking colder and colder now overall oceanic temperatures down to under +.15c deviation from around +.35c deviation last summer.
Weatherbell thus far for June shows only a +.12c for global temperature deviation.
And? Has Weatherbell been lower since you appeared here 8 years ago?

Would you at least TRY to answer the question I posed. How could CO2 cause such extremes in weather/climate?
Is it possible there are other factors causing the warming and so-called record temperatures?
Yes, global warming can cause such extremes, exponentially:
https://davidappell.blogspot.com/2015/07/why-very-warm-events-are-much-more.html
There is no global warming due to AGW and the minor recent global warming that did take place is ending this year, year 2018.
Thus far year 2018 is cooperating with overall sea surface temperatures now less then +.15c above 1981-2010 means in contrast to +.35c during the past summer.
In addition according to satellite data the global temperatures this year are lower then a year ago through today.
One key metric that has to be watched is the North Atlantic which is now in solid negative territory around -.60c from 1981-2010 means.
Greenland Ice very healthy.
As the sun continues in a prolonged solar minimum state this is going to equate to lower overall sea surface temperatures and a slightly higher albedo which in turn will equate to a colder climate.
The weakening geo magnetic field will compound this .
I have been saying this for years and this year 2018 , is the first year that my two solar conditions have been met in order to have the sun result in a more significant climatic impact. Those being 10+ years of sub solar activity in general(which started in year 2005) and within this sub solar activity in general a period of time of very low average value solar parameters(which started in year 2018) meaning solar reading equal to or lower in magnitude that occurs during typical solar minimums with the duration of time of these very low solar values longer then what is typical.
It is happening this year and this is the first time since the ending of the Dalton Minimum, that my two solar conditions are occurring.
In the meantime all the basic premises AGW theory is based on have failed to materialize while the global climate is not even close to being unique.
The theory should have been trashed 20 years ago but has survived due to political agendas.

So enlighten us — what is wrong with the theory?
Does CO2 not absorb in the infrared?
Does the Earth not emit infrared radiation?

What exactly is “surface mass balance?” Area?

I think 2017 stopped the trend.
Salvatore…”I think 2017 stopped the trend”.
Maybe whatever is driving the warming fizzled out following the 2016 EN. Let’s hope so.
CO2 didn’t stop being a greenhouse gas just because there was an El Nino.
The warming will continue, because physics says it has to.
Future is what matters not the past.
That’s a convenient excuse for someone who has repeatedly been wrong about the past.
Don’t think we’ve forgotten about you, Salvatore, the boy who cried wolf.
“Until recently, the mass was roughly in a state of balance. That is, the amount of snow falling on the surface was the same as the mass leaving the ice sheet as melt water runoff or discharge of icebergs. The Greenland Ice Sheet now loses more mass than it receives.
A model of the mass balance that includes data even before the satellite-era shows that since 1840, precipitation (in the form of snow) has risen by 12-20 %, the amount of melt water runoff has increased by approximately 60 %, and the output from glaciers has risen by approximately 40 %.”

Here’s a report on the Greenland ice sheet.
https://www.arctic.noaa.gov/Report-Card/Report-Card-2017/ArtMID/7798/ArticleID/697/Greenland-Ice-Sheet
Last year there was much to do because of a slow melt season, that the Greenland ice sheet might, for the first time in the instrumental record, record a net gain for the year.
An important satellite failed, so the jury may still be out on the close of the year. Read the report, which covers mostly April 2016- April 2017.
If anyone has any updated info on whether 2017 was a mass gain or loss, please bring it here.

What are the chances the fudgers at NOAA will replace it since they discovered their own sat data contradicts their fudged surface data?
What are the odds you would show some actual interest in science and find out, rather than pitching the usual knee-jerk snark?
Unfortunately, the best satellite for making such assessments, the Gravity Recovery and Climate Experiment (GRACE), ceased to operate prior to summer 2017. The replacement satellite, GRACE-Follow-On (GRACE-FO), is scheduled to launch this spring.

Kristian, the hotspot is a theorized result of enhanced warming in the tropical mid troposphere regardless of the source of warming. Its not a unique signature of greenhouse warming.–
Tropical ocean is heat engine of world, I imagine alarmist believe the tropics must get warmer due to greenhouse gases, in order to increase global average temperature.
I would guess this particularly true of those who believe that without any CO2, earth would have average temperature of -18 C, that water vapor is passive and CO2 is a forcing agent.
Also those that believe in the snowball earth, would also believe that tropics is capable of getting cold. And greenhouse gases are only factor which causes the tropics to have average temperature of about 26 C.
“… those who believe that without any CO2, earth would have average temperature of -18 C …”
Without any GREENHOUSE GASES, not just CO2.
Whatever you guess, gbakie, the enhanced warming in the tropical mid troposphere in response to surface warming is an emergent feature in the models regardless of the cause of warming. IE, same for solar, volcanic etc, as well as GHG warming. It’s not a ‘signature’ of warming unique to GHGs. It’s simply a result of heat transport in a warming atmosphere and a decrease in the lapse rate gradient in this region.
Jury is still out on whether this has actually been observed long-term. More solid are observed short-term responses in response to ENSO and volcanic events. It remains an active area of research.

“Large climate uncertainty even with a 1.5-degree temperature increase”
June 7, 2018 by Peter Rüegg, ETH Zurich
https://phys.org/news/2018-06-large-climate-uncertainty-degree-temperature.html#jCp
Do you have a way to reduce the uncertainties? Every climate scientist on the planet would love to hear about it, if you do.
If you do.
Of course, you don’t.
How about scaring women, children and even a pope with planetary doom? How about demanding skeptics be silenced, punished, or jailed? How about demanding billions be spent or pointless tangential research? How about demanding trillions be transferred out of productive economies?
How about a cause that has, for decades, adjusted claims, definitions, data, and even its name to disguise its uncertainties?
Is that your approved method of handling uncertainty, David?
In response the WUWT article trying to say the very weak short lived La Nina is causing this oceanic/global cool off. I do not think so , it may be playing a part but the real reason is the very low solar conditions, in my opinion.
This is the first inning of the cooling. I say as long as solar stays in the tank the cooling will proceed.
ENSO , is not the reason why the temperatures of the oceans and the globe as a whole are dropping.
The REAL reason is due to the very low solar activity we have had for 10+ years now and within this sub solar activity the very low average solar parameters we now have in year 2018. Year 2018 being a transitional year. This is the first time since the Dalton solar minimum ended that solar is sufficiently low to have a major climatic impact.
I have been saying this for years. Very low solar equates to overall lower sea surface temperatures and a slightly higher albedo which in turn will equate to lower over all global temperatures. A weakening geo magnetic field compounding the solar effects.
I have been saying this for years and ENSO is not the answer this time. If anything if you want to talk oceanic influence on global temperatures look to the North Atlantic which has cooled considerably.
As long as solar stays in the tank this cooling trend will be continuing.
Climate scientist could not see a change in a climatic trend coming if it starred them in the face. They as a whole are useless, all they do is promote AGW.
Maybe this can finally put an end to AGW theory which is a shame.

The recent EL NINO, was much stronger then this recent La Nina.
Just of note.
It is the surface oceanic temperatures which matter when it come to the global climate.
In addition the surface oceanic temperature changes are good indicators as to what is happening with the oceans as a whole.
Again I am looking toward the future not the past which is what is constantly being brought up.
It is where do we go from here and I say lower oceanic and global temperatures for years as long as solar stays sub par as it is now.
Salvatore Del Prete says:
“It is the surface oceanic temperatures which matter”.
But your prediction depends on warming in the deep ocean.
To keep it away from the surface.
Salvatore Del Prete says:
It is the surface oceanic temperatures which matter when it come to the global climate.
Why does it matter more than ocean heat content?
They all matter but I think surface oceanic temperatures cooling will over time translate to less ocean heat content.
Let me put it this way, if ocean heat content keeps increasing I do not think over the long run it would be possible to have sustained lower overall sea surface temperatures.
We will have to see if lower overall sea surface temperatures continue.
Now even +.13c deviation is still on the high side. I want to see if they keep lowering or not.
From NOAA,
“The average depth of the ocean is about 12,100 feet. The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 36,200 feet deep. It is named after the HMS Challenger, whose crew first sounded the depths of the trench in 1875.”
So, Sal, why do you think the ocean surface (measured in centimeters?) represents the ocean as a whole?
What has been observed is that colder ocean is a colder global average temperature, and a warmer ocean has higher global average temperature.
What has been imagined is that heat has been “lost” in the ocean and it is heat “lost” in the ocean which is global warming.
Not lost. But over 90% of the trapped heat goes into the ocean.
gbaikie…”What has been imagined is that heat has been lost in the ocean and it is heat lost in the ocean which is global warming”.
I don’t think it is imagination, it’s more desperation. It’s like the dog ate my homework.
Trenberth was in a pickle following Climategate where he was caught in one email expressing frustration over his inability to find a warming signal. Shortly thereafter he came up with the inane theory about the oceans capturing the missing heat.
Of course, NOAA then went out and fudged the SST to find Trenberth’s missing warming.
It’s just moving the goalposts.
Kevin Trenberth:
“In my case, one cherry-picked email quote has gone viral and at last check it was featured in over 107,000 items (in Google). Here is the quote: “The fact is that we can’t account for the lack of warming at the moment and it is a travesty that we can’t.” It is amazing to see this particular quote lambasted so often. It stems from a paper I published this year bemoaning our inability to effectively monitor the energy flows associated with short-term climate variability. It is quite clear from the paper that I was not questioning the link between anthropogenic greenhouse gas emissions and warming, or even suggesting that recent temperatures are unusual in the context of short-term natural variability.
http://www.cgd.ucar.edu/staff/trenbert/emails/
Centimeters of ocean surface is average global temperature (it is 70% of Earth surface , it is warmer in terms of average temperature as compared land, and it average temperature of 17 C, warms the land surface average temperature which is about 10 C.
So it is the depth of centimeters which reflects now, or reflects/makes “weather”, though it the deeper waters temperature which determines global climate or long term temperatures on Earth.
Gbaikie
“So it is the depth of centimeters which reflects now, or reflects/makes weather, though it the deeper waters temperature which determines global climate or long term temperatures on Earth.”

There is a clear trend of diminishing the amount of melted ice i.e. diminishing of the amount of heat available in the arctic region.
Someone can maybe find whether this is due to the air temperature during the melting period or due to the SST of the arctic sea.
*
At a first glance I had the impression you’re right.
But then I went to my Excel Colorado spreadsheets and thought: no, esalil isn’t.
The first reason is the good match between the inverted Arctic sea ice extent/area series and oceanic / tropospheric temperatutes in the Arctic region:
http://4gp.me/bbtc/1528395784542/001.jpg
The anomalies were converted by scaling to their respective percentiles within the period, as comparing degrees with km2 makes few sense.
The second reason is that as opposed to your example, time series of yearly maxima minus yearly minima do not show any negative trend, neither for 1979-2017:
http://4gp.me/bbtc/1528396114955/001.jpg
nor for the DMI volume time series (2003-2017):
http://4GP.ME/bbtc/1528396173381/001.jpg
Maybe the sea ice volume / thickness time series differ from the pack ice area, but certainly not to an extent such that it would show a negative trend.

Yes, but their hindsight is cherry picked and delusional. They refuse to see evidence of a global Little Ice Age where global temps dropped 1C to 2C below average.
The LIA had two solar incidents over it’s 400 years, Dalton and Maunder, and was preceded by other solar minima. There were other solar periods predating those and the following article suggests the Medieval Warm Period, pre-dating the LIA, may have been caused by solar activity as well.
****PLACEHOLDER FOR URL TEST****

The reasoning offered by alarmists re CO2 is ‘what else could it be’? It’s there is the sky every day. Solar activity is a far better explanation for warming/cooling than any man-made issue.
There is mention of a 200 year solar cycle in this article. Alarmists have claimed shorter solar cycles cannot produce the kind of warming we are experiencing but the 200 year cycle can.

Salvatore…”There is no global warming due to AGW and the minor recent global warming that did take place is ending this year, year 2018″.
There is certainly something odd going on this year. Here’s an article on the snow in Eastern Canada in early June. Here in Vancouver, we went from temperatures of 20+C in May to a very sudden reversal on June 1st of much cooler weather.
https://www.msn.com/en-ca/weather/topstories/east-snow-falling-like-a-slow-clap-when-does-it-end/ar-AAydz3q?li=AAggNb9&ocid=mailsignout
I get it that weather is not climate but get this from the article:
“Late last week saw high temperatures treading into record-breaking territory across much of the Maritimes, but it was a short-lived burst as a cold front shortly after sent frosty air back into the region. Miramichi, N.B. for example, went from breaking a 140-year-old record high last Friday, to a 91-year-old record low on Sunday”.
No matter how alarmists twist the story, there is no way CO2 could cause such extremes, even though modelers have claimed as much.
Time to throw out the AGW theory so we can study exactly what forces are at work.
Sorry, where have “modellers” claimed that day-to-day variation is “caused by CO2”?
bob/des…”Sorry, where have modellers claimed that day-to-day variation is caused by CO2?”
You have likely been in the Outback too long interfering with sheep. It has become a joke, the way alarmists blame everything on anthropogenic warming. They got it from modelers and their professional enthusiast who have claimed CO2 can explain cooling.
I thought you’d have been up on that at alarm central, aka realclimate. SkS borrows from them regularly and the resident guru there is Pierrehumbert who uses all forms of nonsense science to equate CO2 to cooling as well as warming.

Explain the mechanism. I am not interested in what wannabee physicists program incorrectly into climate models, I want to see the physics that explains how a gas making up 0.04% of the atmosphere can cause extreme temperatures, both warming and cooling.
The mechanism is simply the nature of normal distributions. I proved it mathematically here:

“There is a clear trend of diminishing the amount of melted ice i.e. diminishing of the amount of heat available in the arctic region.”
That could be true, even if melt season loss is increasing as a percentage. Here’s a simple example:
If maxima is 1000 Km2, and minima is 900 Km2, that’s a loss of 100 Km2 = 10%
If maxima is only 800 Km2, a larger percentage loss, say 12%, equals a smaller actual loss (96 Km2).

What?? Are you thinking there is almost no difference between maxima and minima arctic sea ice?
The explanation I posed (borrowed from Neven’s blog) relates to seasonal changes to the entire Arctic Ocean ice pack, not just the area north of 80′.
The conversation had been about the ice N of 80N. Of course summertime sea ice extent has diminished over the whole Arctic.

Changes in ocean circulation (i.e. ENSO/La nina) can cause more surface heat to be transported downwards. Cooler surface, warmer subsurface.
On the other hand, why would a decline in solar cause only the surface to cool, but allow the ocean as a whole to continue warming?
That’s the big hole in your theory.
We have to see what happens going forward not what has happened.
Transport delay. There’s always a delay.
How much of a delay?

Let me guess. Their thesis is that the data has changed over time, therefore there must be fudging.
Guess all you want, between March and April 2018 fully 953 changes were made to the “Land-Ocean Temperature Index” LOTI
https://data.giss.nasa.gov/gistemp/tabledata_v3/GLB.Ts+dSST.txt
that GISS publishes monthly. That’s 55% of the 1740 monthly entries since 1880 where the LOTI data starts. And 160 of those changes were made to data from the 19th century. On average there are only 50 to 100 changes made every month and sometimes there aren’t any – I should look to see that’s in the summer when all the heavy hitters at GISS and NOAA are off on vacation. Whatever the reason for the monthly changes they do add up. Here’s what a chart of that summation looks like:
http://oi68.tinypic.com/wck4lc.jpg
That chart is 3 years old now, but I’d be surprised if it’s changed much since then. Each point on that graph indicates the overall average change made to the year. And as you can see, most of the changes prior to 1980 are negative and all of the changes since then are positive. It’s a matter of opinion as to why those changes form a pattern, but it’s a matter of fact that they do.
It certainly does not lend confidence. If it changed so much today, who’s to say what it will be in the future?
Who controls the past controls the future. Who controls the present controls the past.
― George Orwell, 1984
1) GHCN receive data from a few thousand stations by the 8th of each month. These are the ‘near real-time’ updates. There were about 1500 stations 20 years ago, and there are more of these now.
After that more data from weather services keep coming in for the same month that are not included in the batch that are part of the near real-time stream.
Information for a certain month keeps accumulating after the data are first posted online, and then the data are updated to reflect any new averages. You can see many changes occur to monthly values, although typically they are not large.
2) Revisions to methods can change the data. The data compilers do not and never have considered their data perfect. It isn’t.
3) UAH also make data revisions that are not publicly documented – no one seems to be interested in that. For instance, there was a large-scale change to anomalies from about 2000 onwards a year or so ago. No peer-reviewed study accompanied this change, and no one would have known if it hadn’t been given a sentence in one of Dr Spencer’s updates. I saw it many times with 5.5 and 5.6 versions.
There are plenty of changes to UAH monthly anomalies between the Dec 2017 update and the current one 6 months later. I just checked.
The problem with all criticism of the global temp data sets is that critics have zero curiosity about the reasons for the change, and instead take the fact of change as something nefarious – instead of taking the opinion that diligent people run near-constant quality control on imperfect data, and receive constant updates to the actual data that change the averages for the most recent months and years.
Basically, people snark in willful ignorance. Actually investigating why changes occur is totally eclipsed by their need to cast aspersions and fulfill their political narrative.
‘Skeptics’ my arse.
Regarding your “Arse,” back in January this reply to the question of why 100 year old data is being changed was supplied:
Your main concern seems to be why data from 1880 get affected by the addition of 2018 January data and a few late reports from the end of 2017. To illustrate that, assume that a station moves or gets a new instrument that is placed in a different location than the old one, so that the measured temperatures are now e.g. about half a degree higher than before. To make the temperature series for that station consistent, you will either have to lower all new readings by that amount or to increase the old readings once and for all by half a degree. The second option is preferred, because you can use future readings as they are, rather than having to remember to change them. However, it has the consequence that such a change impacts all the old data back to the beginning of the station record.
Hope that answers your concern.

If that explains why there’s a pattern of lowering old records and warming up the recent entries, I fail to understand how that works. Maybe you can cut through the mumbo-jumbo to discern why that is.
Granted, Dr. Ruedy wasn’t asked to explain why since 2005 there are nearly 100,000 changes made to the monthly LOTI publications and why they constitute an obvious pattern.
Another useful article debunking GHE and AGW from a Ph.D in chemical engineering, who has worked for the NASA Jet Propulsion Laboratory.
Chemical engineering at an undergrad level is one of the toughest academic studies at university. To get a Ph.D in the field is something else. He certainly knows how heat and radiative heat transfer works.
I emphasize ‘works’, not the theory, but how it is applied.
http://www.webcommentary.com/php/ShowArticle.php?id=latourp&date=130708
“The GHGT does not follow the rate of radiant energy transfer law used commercially by chemical engineers: Q/s = ET4 – at4. Heat transfers in only one direction, not simultaneously in two….
E = emissivity of radiating surface. Varies with its temperature, roughness and if a metal, degree of oxidation. Large variations are possible in a single material, and,
a = absorp-tivity of atmosphere. Depends on factors affecting emissivity and in addition on the quality of the incident radiation, measured by its distribution in the spectrum. One may assign two subscripts to a, the first to indicate the temperature of the receiver and the second that of the incident radiation.]
GHGT invented the back-radiation mechanism unknown to physics, transferring heat from a cold body to a warmer one, warming it further. In Nov 2011 I proved if it did, it would be a perpetual motion machine…”
Gordo, It appears that you are up to your old tricks again. You’ve posted a link to another claim that AGW violates the 2nd Law, even though it doesn’t and after I’ve shown clearly that “back radiation” can warm a solid body. How convenient that your commentator references a 1950 source, which isn’t available on the net, so we can’t easily check what was actually written.
You just can’t understand that these guys (at slayingtheskydragon) are wrong.
Gordon is well aware that he is misquoting the 2nd law.
He just doesn’t care about the truth, is all. To him, it means more to satisfy his ideology than to correctly present the science.
For some reason, some people are like that.
DA…”Gordon is well aware that he is misquoting the 2nd law”.
I have corresponded with Ralf Tscheuschner of Gerlich and Tscheuschner, who works in the field of thermodynamics, and he agrees with my version. The author of the article I just posted agrees with it too and he is a chemical engineer (Ph.D) who works in a thermodynamics-related field.
Heck, even Clausius, who wrote the law, agrees with me. Heat can NEVER be transferred by its own means from a colder body to a warmer body.
What is it about that definition that bothers you? Is it possible you don’t understand the 2nd law?
Gordon Robertson wrote:

Stop lying, Gordon. Just stop it.
Please quote for us exactly the Clausius version of the second law.
Cite your source.
swannie…”Gordo, It appears that you are up to your old tricks again. Youve posted a link to another claim that AGW violates the 2nd Law, even though it doesnt and after Ive shown clearly that back radiation can warm a solid body”.
The author of the article has a Ph.D in chemical engineering and applies heat equations on a regular basis. He claims heat can only flow one way, hot to cold. I presume he means without compensation because he agrees that refrig.e.rators can be set up to allow a two way flow.
Why don’t you write to him and offer your theories?
Gordon wrote:
He claims heat can only flow one way, hot to cold.
He’s wrong, unless he has some special, adabatic situation in mind.
Does he, Gordon?
Gordo, I see you are still using the old “appeal to authority” game. You might want to look at Latour’s more recent work for a good laugh. He accepts Stefan-Boltzman as the operational model and includes “back radiation” transfer from cool to warm, writing:
The rest of his analysis completely misses the physics at work in the atmosphere, which is that he includes only radiative transfer, leaving out convection, which causes most of the transfer from the surface thru the lower atmosphere. He also misses the fact that layers in the atmosphere radiate in both upward and downward directions (on average), thus the energy flowing out of each layer is split 50/50 into those directions. When multiple layers are analyzed, the result is the lapse rate in temperature. There’s much more to it than simple radiant energy transfer.
Gordon Robertson
It is true, heat (quantity of energy that transfers from a hot object to a cold object) cannot transfer from a cold object to a hotter one.
Still no-one is making the claim that it does. Energy, IR, will transfer from cold to hot object. Heat flow is stated as a NET energy flow. It can be negative, positive or zero.
Once again for you Gordon (this is what barry demonstrated Clausius was saying in his own works that you lied about and I confronted you on lying intentionally).
http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/seclaw.html
“It is important to note that when it is stated that energy will not spontaneously flow from a cold object to a hot object, that statement is referring to net transfer of energy. Energy can transfer from the cold object to the hot object either by transfer of energetic particles or electromagnetic radiation, but the net transfer will be from the hot object to the cold object in any spontaneous process. Work is required to transfer net energy to the hot object.”
E. Swanson shows you that the colder green plate DOES (in the real world not in your make believe fantasy science world) increase the temperature of the powered blue plate. The green plate transfers ENERGY to the Blue plate that it must get rid of by increasing in temperature. It is really easy to understand. It is also verified with real world experimentation.
Salvatore
You don’t want to answer my question, do you?
“On the other hand, why would a decline in solar cause only the surface to cool, but allow the ocean as a whole to continue warming?”
********
“Confirmation bias is a phenomenon wherein decision makers have been shown to actively seek out and assign more weight to evidence that confirms their hypothesis, and ignore or underweigh evidence that could disconfirm their hypothesis.”
If the surface oceanic waters continue to cool it will translate to the entire ocean over time. That is my answer.
That is only your hope, Salvatore, not anything based on science.

Taking the advice from La Pangolina I did generate graphs and post them to an internet site hoping they will show up for you to look at.
I am still of the opinion that this information will have zero impact on you.
Maybe someone else can use it. I am hoping that CO2isLife will look at it, not sure they will.
YOU: “normanThanks for the advice. Is it worth the effort? The plots I made show that through 1 meter CO2 absorbs nearly 100% (transmits zero) at the 15 micron wavelength
Good grief, Norman, the two graphs floating around here show CO2 absorbing about 5% at 15 microns. Thats about 5% of nothing.”
I do not know what graphs you are talking about. Definitely you are totally wrong. Nothing unusual with that. Most everything you post is wrong. You don’t care, you won’t correct your flaws and bad thought process. No one has been able to reason with you yet, I do not expect to be able to.
The graphs were created at
http://www.spectralcalc.com/spectral_browser/db_intensity.php
I used the Gas-Cell simulator. I set the wavelength to 14-16 microns (it converts it to wavenumber for the graphs). For the VMR
Volume Mixing Ratio I used 0.03 for Water Vapor (3% of atmosphere).
I used 0.0004 for Carbon Dioxide graphs (0.04% of atmosphere).
The graphs reflect the concentration in the atmosphere.
I made graphs at 1 meter, 10 meter and 100 meter. I set the graph to show how much IR is absorbed through the path lengths at surface atmosphere pressure.
You are very wrong Gordon Robertson. Your posts are poor and mostly meaningless. You are a negative weight to valid skeptics.

That forecast is for lower temperatures.
Salvatore, you’re always been trying to forecast the future. And you’ve always been wrong.
Why should anyone believe you this time? Why do you think you have any credibility left?
Maybe not to you but I take this recent trend as perhaps the start of new long term trend.
According to my studies no further global warming will take place the question is how much cooling. So far so good.

This says it all.
The warming last century is next to nothing in contrast.
How does the current rate of warming compare to back then?
Esalil, LP
The same math idea is relevant to either volume, area or extent. Here it is using sea ice volume:
If maxima is 1000 Km^3, and minima is 900 Km^3, thats a seasonal loss of 100 Km^3 = 10%
If maxima is only 800 Km^3, then a larger percentage loss during melt season, say 12%, equals a smaller actual loss (96 Km^3).
That is evident.
La Pangolina, Snape: You did not want to comprehend my message at all. I wanted to tell that there must have been diminishing amount of heat available in the arctic region during the melting season because the ABSOLUTE amount on the melting ice VOLUME has been decreasing. It was 22% less in the year 2017 compared to year 2003. You cannot calculate this from the ice extent if you do not know the ice thickness. Relative ice loss offered by Snape does not tell the the amount of the heat needed for the melting.
As I wrote above, esalil, I await thickness data I can compare with area (alias pack ice) data.
We will then see.
La Pangolina: you have not used the link I provided. There is only the daily ice volume presented.
Of course I did.

“Apparently the subset of papers with the worst record of replication is high-profile climate contrarian papers:”
https://link.springer.com/article/10.1007/s00704-015-1597-5
A brief review of that paper reveals a few major flaws.
The subject papers were admittedly cherry picked.
There were no warmist papers evaluated as controls.
The methodology is insufficient to enable replication.
Essentially, the paper is guilty of the same mistakes it was attempting to expose in other papers.
Speaking of replication, are you aware that UAH is the outlier here, in disagreement with RSS, NO_AA, GI_SS, Had_CRUT, JMA, and BEST?
Appell, you behave exactly like Robertson: you deliberately ignore contradictions to what you pretend.
As I wrote in answer to such comments you published, the disagreement between UAH and JMA is negligible.
30-yr trends:
UAH_LT v6.0: +0.13 C/dec
JMA_ global surface: +0.15 C/dec
NO__AA global surface: +0.18 C/dec
RS_S LT v4: +0.21 C/dec
GI_S_S global surface: +0.19 C/dec
Had_CRUT v4.6 global surface: +0.18 C/dec
So, OK, J_M_A is the lowest of the others. That still doesn’t lend much support to UAH. Why do they differ so much from R_SS? UAH has always been a low outlier — recall the travails over their sign error in the late ’90s. It took year for them to admit their mistake. Somehow they always manage to come in on the low side.
Trends over the full span of the satellite data (1979+):
UAH 0.127
JMA 0.135
NOAA 0.166
GISS 0.173
RSS 0.193

Why do you think you can here decide wether UAH or RSS is the outlier?
Why don’t you let the real specialists decide who of both is right?
What the hell are we in comparison with Spencer/Christy and Mears/Wentz?
DA…”Speaking of replication, are you aware that UAH is the outlier here, in disagreement with RSS, NO_AA, GI_SS, Had_CRUT, JMA, and BEST?”
You forgot to mention that UAH is the only time series offered with integrity. The rest are lying, scumbag alarmist cheaters.
Why do you say UAH is the only group with “integrity?”
Based on what?
Gordo, there are those of us who think that the UAH data misrepresents actual changes in temperature. For example, as I demonstrated in my 2003 GRL paper, the UAH data over the Antarctic may be contaminated by changes in sea-ice. RSS simply deletes data from 70S to the South Pole, since the high elevations over the Antarctic intrude into the MSU/AMSU TLT product. Spencer and Christy used to warn their “customers” about using their data from the Antarctic, but they have let that warning disappear from their later works. I conclude that RSS is likely to be closer to reality than UAH in the Southern Hemisphere. And that’s just one problem area…
swannie…”Gordo, there are those of us who think that the UAH data misrepresents actual changes in temperature”.
Yes….and you set up an experiment in which you concluded back-radiation from a cooler target could warm a much warmer source.
It does not surprise me then that you think UAH data is compromised.
Gordo, It’s not what I “think”, it’s what I conclude from my analysis of the data. You, however, appear unable to analyze my Green Plate demo, offering only polemic assertions based on your deviant interpretation of early theoretical work in thermodynamics.

So I will have to respond to Norman’s obstinate ramblings over here instead. Sorry about that to everyone, because, yes, it’s a tedious exercise …
Norm’s last post:

My response:
Norm,
Just stop it. For your own sake, stop it. You’re only embarrassing yourself digging your heels in like you do. There is no way you can argue your way to ‘victory’ on this issue. There are heat fluxes in a steady state. The ASR and the OLR are both heat fluxes. You are wrong. Period.
Stop it.
Again, all you need to know is that there are temperature differences within the Earth system and between the Earth and its surroundings (the Sun is hotter, space is colder).
If there are temperature differences, there are heat fluxes, Norm. That is a universal FACT. And you do not get to just simply deny this because it suits your particular world view. It is not a matter of opinion. It’s PHYSICS.
Steady state:
https://en.wikipedia.org/wiki/Steady_state
Norm,
Here’s a nice little video for you that I found. You should watch it and gain at least some degree of basic-level understanding of the kind of thermodynamic state the Earth is in. As you can tell, your mind is riddled by pretty profound misconceptions about the nature of heat and heat flow. Your clearly expressed idea that there are apparently no heat flux coming into the Earth system in its steady state, no heat flux moving through the Earth system in its steady state, and no heat flux escaping the Earth system in its steady state, perfectly illustrates this point.
You need to stop being so stubborn and start learning a little.

I think you neglected to read my last post on the other thread. I did agree that you would have heat flows but I am not sure how useful each heat flow would be. If you wanted to layer the atmosphere you could have hundreds of heat flows from a warmer portion of the atmosphere to a colder layer above. You could call all these heat flows, not sure of how significant it would be.
Also, in heat transfer problems, they are not interested in each individual heat flow. They are interested in the net of all the heat flows to see how it will affect a surface you are wanting information about.
The only heat flow or flux that would be of value for the Earth system would be the NET or total. Then you could determine if the Earth is warming or cooling.
Case of point. You have that the Surface to Atmosphere heat flux is 53 W/m^2. Of what value is this information. It is not a measured value, it is derived from energy flows. You could not tell by measuring the surface if there was a net heat flow loss nor could you tell by measuring the atmosphere temperature. They are in a steady state and not changing (over the entire globe). What value is this 53 W/m^2? You can’t tell what the surface is doing, you can’t tell what the atmosphere is doing.
If you have the surface heat up and the DWIR increase at the same rate you would still get 53 W/m^2 which tells you NOTHING of value and you need to calculate it anyway from the measured energy flows.
So again I really don’t know what your point is or what you are trying to state. If you feel that showing graphs of heat flows are the way to go, do it but you better have hundreds of heat flows for the atmosphere to be accurate.
Far simpler just to model energy flows in and out and see what the balance is. What is the overall heat flux. The rest is just pointless.
norman…”Also, in heat transfer problems, they are not interested in each individual heat flow. They are interested in the net of all the heat flows to see how it will affect a surface you are wanting information about”.
There is no net heat flow with radiation, there is only a temperature difference. Heat does not flow through the air unless by convection therefore there is no net thermal energy to sum.
Also, there is only a one way EM flow from our planet to space, there is no EM flowing in the way from the frigid void of space, only EM from the Sun.
S-B===> q = ebA(T0^4 – T^4)
q should represent the electromagnetic energy density but it’s not heat. It does represent the heat loss at the surface but that heat loss takes place within the surface as atoms become less energetic after emitting EM.
I pointed out before that if you equate W/m^2 to EM it must be as potential thermal energy. There is no acting heat energy (thermally-related kinetic energy) in EM, only the potential to create thermal energy is an absorbing mass.
Gordon Robertson says:
Heat does not flow through the air unless by convection therefore there is no net thermal energy to sum.
So explain a sunburn.
DA…”So explain a sunburn”.
Why not go to university and learn? Actually, you could figure that out taking a minor course about electromagnetic energy, what is is, and how it interacts with molecules in substances like the human skin.
Instead, you go on and on asking the same dumb old questions.
EM carries energy, commonly referred to as “heat” for IR, or UV-B for the radiation that causes sunburns.
Heat is just energy. EM is just energy. One easily translates into the other.
Gordon Robertson
Because you repeat things over and over does not make them correct, it just makes you a crackpot.
YOU keep making this stupid claim that Kristian even corrects you upon and yet you are far too stupid to correct your errors.
I did have the concept of equilibrium mixed up with Steady State, I read up on it and corrected my error and learned. You are not intelligent enough to learn anything. I think you might be a human parrot. You just repeat nonsense every chance you get and want a cracker proud of your own stupid thoughts.
YOUR stupidity on display: “There is no net heat flow with radiation, there is only a temperature difference. Heat does not flow through the air unless by convection therefore there is no net thermal energy to sum.”
Gordon I found this engineering heat transfer webpage. I think you should read it and quit posting stupid comments.
https://www.engineersedge.com/heat_transfer/heat_transfer_table_content.htm
That is the general webpage
Specific to radiant heat transfer.
https://www.engineersedge.com/heat_transfer/thermal_radiation.htm
DA…”EM carries energy, commonly referred to as heat for IR, or UV-B for the radiation that causes sunburns”.
So let me get this straight electromagnetic ENERGY carries THERMAL energy as heat.
So here’s what we have to do…if you are right. We have to go back and change the concepts introduced by Bohr in 1913 and Schrodinger in 1925, which are both the basis of quantum theory. We have to redefine atomic theory to eliminate the electron, which many today think converts heat to EM and EM back to heat.
What do you think the chances are of that happening?
Ironically, you have already agreed that EM is an electric field perpendicular to a magnetic field which is defined primarily by its frequency and partly by its intensity as E = hf. Where do you see any reference to heat in that definition?
Where do you see the atoms required by heat to exist?
If you are right, then heat is transferred from a transmitting radio antenna to a receiving antenna by EM.
In the S-B equation, q = ebA(T0^4 – T^4), where do you see a reference to heat in the radiant energy density, q? All I see is T0 and T which represent the temperatures of the transmitting and receiving bodies, consisting of atoms/molecules.
Once that EM leaves the transmitting body and become far-field radiation, it has no heat associated with it. It has the potential to be converted back to heat but it lacks the kinetic energy ASSOCIATED with the motion of atoms.
norman…I was reading through the textbook you posted on Heat Tranfser and I see where you are getting the nonsense about heat being additive, especially in a two-way transfer.
The book states:
“Radiant heat exchange.
Suppose that a heated object (1 in Fig. 1.16) radiates to some other object (2). Then if both objects are thermally black, the net heat transferred from object1 to object2, Qnet, is the difference between Q1-2”.
That statement is nonsense and they do not back it up with an example of two way radiative transfer. Instead, they give this equation:
Qnet = A[e1(T) – e2(T)] = fi.A1 (T1^4 – T2^4)
Clearly, the 2nd part of this equation is the Stefan-Boltzmann equation, which makes it totally clear that energy is transferred in the direction of the temperature gradient. The first part is nonsense since the emissivity of body 1 minus the emissivity of body 2 clearly does not equal the Stefan-Boltzmann equation.
Then they talk about a ‘view factor’ which involves how much of the EM from body 1 is intercepted by body 2, but they do not talk about how much of body 2 is intercepted by body 1.
The example they give is equally ambiguous.
“A black thermocouple measures the temperature in a chamber with black walls. If the air around the thermocouple is at 20C, the walls are at 100C, and the heat transfer coefficient between the thermocouple and the air is 15 W/m2 K, what temperature will the thermocouple read”?
Solution.
The heat convected away from the thermocouple by the air must exactly balance that radiated to it by the hot walls if the system is steady. Furthermore, F1-2 is unity since the thermocouple is enclosed:
***some bogus math*** then this brilliant solution…
Trial-and-error solution of this equation yields Ttc = 51C.
*********
Nowhere do they address either a two way heat transfer or a two-way EM transfer. Instead, they make an inference about convection and that was not specified in the question.
This is bs science aimed at newbie students in thermodynamics and nowhere in this book do they give an example of what you are talking about.
A word to the wise. Read beginner’s text books with a good deal of skepticism. They tend to dumb subjects down and in doing so they can be seriously misleading.
I would suggest you forget about summing heats, especially in two way flows, and go with the Clausius definition of the 2nd law. Unless of course you are masochistic like swannie and you are trying to disprove the 2nd law throw bogus back-radiation fantasies.
Gordon is still lying about the 2nd law. I don’t think he’ll ever stop.
Gordo, If a theory, such as your peculiar interpretation of the Second Law, fails to explain experimental results, it’s most likely the fault of the theory. You have yet to provide a detailed critique of my Green Plate demos. You would rather spend your efforts looking for yet another authority to point to as proof of your denialist world view.
swannie…”Gordo, If a theory, such as your peculiar interpretation of the Second Law, fails to explain experimental results, its most likely the fault of the theory”.
Or the fault of the experimenter. That is, drawing false conclusions.
Gordon, show an experiment that proves your version of the 2nd law.

Which textbook link are you referring to?
Read the following book:
https://tinyurl.com/HeatAndMassTransfer
First paragraph on page 27 of the book (page 48 of the pdf)
norman…”Which textbook link are you referring to?”
One you posted a while back called A Heat Transfer Textbook by Lienhard.
The link posted by Kristian is done by Lienhard. Although the video is relatively sound I think Lienhard himself tends toward bombast and smugness.
In all the examples he shows of the frying pan on the heater the handle is clearly visible. The last shot taken with an IR camera shows the handle partially hidden and if you capture the scene and clear it up a bit there does not appear to be a handle on it.
I think Lienhard may have fudged the photo to make a point. In the earlier examples he clearly shows a hot spot on the handle where it connects to the pan body.
For some reason, Lienhard is suggesting the handle EXCHANGES heat with the room air. I think he is all wet with his radiation theories, as is evident in his book.
