Florida Major Hurricane Strikes: Still No Trend

October 11th, 2018 by Roy W. Spencer, Ph. D.

Note: The first plot had Michael’s wind speed plotted incorrectly, which has been fixed.

I’ve updated a plot of Florida major hurricane strikes since 1900 with Hurricane Michael, and the result is that there is still no trend in either intensity or frequency of strikes over the last 118 years:

This is based upon National Hurricane Center data. The trend line in intensity is flat, and the trend line in number of storms (not shown) is insignificantly downward.

Nevertheless, the usual fearmongers are claiming Hurricane Michael is somehow tied to climate change.

After all, the Gulf of Mexico is unusually warm, right?

Yes, but if you look at the history of Jul-Aug-Sept average sea surface temperature (SST) anomalies over the eastern Gulf (available here, 25N-30N, 80W-90W), you will see that since 1860, this summer is only the 9th warmest in the eastern Gulf of Mexico.

Even more astounding is that out of the top 10 warmest Gulf years since 1860, 7 occurred before 1970, which is before we experienced any significant warming.

So, all the “experts” can do is make vague claims about how major hurricanes like Michael are what we can expect more of in a warming world, but the data show that – so far at least – the data do not support the theory.

Major hurricanes are part of nature. As evidence of this, I will also remind people of the study of lake bottom sediments in Western Lake in the Florida panhandle, not far from where Michael made landfall, that showed the last 1,000 years have been relatively quiet for Category 4 to 5 hurricanes, but the period from 1,000 to 3,400 years ago was a “hyperactive” period for intense landfalls at that location.

Hurricane strikes in the U.S. are notoriously variable, as evidenced by the recent (and unprecedented) 11+ year “drought” in major hurricane landfalls, which was finally broken in 2017.

Where were the claims that the hurricane drought was due to global warming?

Crickets.

Attributing the latest hurricane in any way to global warming is the ultimate in cherry-picking the data. In fact, they don’t even show the data.

Which brings us back to those vague claims by the experts.

UPDATE:

I also included Michael in the count of ALL U.S. landfalling major hurricanes, again from NHC data. The marked downward trend since the 1930s, 40s, and 50s is quite evident:

Where is the news story about THAT?

More crickets.

    “So, all the experts can do is make vague claims about how major hurricanes like Michael are what we can expect more of in a warming world, but the data show that so far at least the data do not support the theory.”

    Are you saying that hurricanes passing over warmer water, all else being equal, do not become stronger?

    In the case of Michael, its rapid strengthening occurred over water that was ~ 2 C above normal.

    Clearly the amount of warming of the gulf we have had so far due to climate change has not been so large, 0.6 C or so?, that it overwhelms natural variations. But if warming continues then at some point it would matter.

    • Bart says:

      “Are you saying that hurricanes passing over warmer water, all else being equal, do not become stronger?”

      Sure. In a physically impossible fantasy scenario, you can make hurricanes do whatever you like.

      Storms are driven by temperature differentials, not absolute temperatures. The notion that CO2 will heat the water, but not the air, is completely bass-ackwards.

      • Nate says:

        See below. Also with Michael, it probably passed over the Loop Current which has deep warm water.

        • Bart says:

          Ignaratio elenchi. The hypothesized impact of GHGs is to reduce temperature gradients. Reduce the gradients, and you reduce storm activity.

        • Nate says:

          I see the strategy. Ignore my rebuttal and repeat the claim.

          • Bart says:

            Your rebuttal was irrelevant. That is what ignoratio elenchi means.

          • Nate says:

            You make vague claims about gradients. I talk about which gradients actually matter for hurricanes. Irrelevant? That’s willful ignorance.

          • Bart says:

            “I talk about which gradients actually matter for hurricanes.”

            There are no increasing gradients that can reasonably be linked to the increase in CO2 concentration as the causative agent. Increasing CO2 necessarily decreases the gradients.

            The “extreme weather” meme is a marketing ploy, not science.

      • David Appell says:

        Bart says:
        The notion that CO2 will heat the water, but not the air, is completely bass-ackwards.

        No one claims that.

        CO2 heats the air. The air is in contact with the water. The water warms.

        I don’t know how much direct IR warms the ocean, but the above holds in any case.

        • Mike Flynn says:

          DA,

          You wrote –

          “CO2 heats the air.” Are you sure? It doesn’t seem to apply in the absence of a heat source, does it?

          Air cools at night. Does this mean that CO2 cools the air as well? Marvellous stuff, this CO2!

          All seems a bit delusional. Heats and cools simultaneously – the average would seem to be zero. No effect at all. Gee, maybe you’re right, after all! Only joking. Increasing the amount of CO2 between the Sun and a thermometer makes the thermometer colder, not hotter. Not as much energy reaches the thermometer.

          Press on believing in the magical heating abilities of CO2.

          Cheers.

        • Bart says:

          You are missing the point. Storm power is driven by the temperature gradient. Even if what you say were true, it wouldn’t result in greater storm power. It would result in less.

          • Nate says:

            Does the engine of Hummer have a bigger temperature gradient than the engine of a Civic? Is that what makes the Hummer more powerful?

            No. The difference is the rate of fuel pumped in and burned.

          • Bart says:

            Inappropriate analogy. The engine and fuel source is the same here. The one that runs with a smaller gradient between internal and external temperature will be less powerful than the other.

          • nate says:

            “Inappropriate analogy”

            Why inappropriate?

            ” The engine and fuel source is the same here.”

            Never said otherwise.

            “The one that runs with a smaller gradient between internal and external temperature will be less powerful than the other.”

            As usual, you are just making declarative statements, not backed up by real facts about the specifics of hurricanes. Pointless.

  2. Nate says:

    If I start your plot at 1900, the trend is flat.

    The plot is essentially looking at a series of Craps rolls. Not meaningful.

    • Nate says:

      I’m referring to the 2nd plot.

    • Nate says:

      To reinforce the point, if I start the plot in 1960, the trend is also flat.

      • Steve S. says:

        And if I start the plot in 1970 it’s uphill.*

        It is a bit disingenuous to start that 2nd plot in 1930, in that the 1940s were the highest count of major hurricane landfalls since the 1850s.
        http://www.nhc.noaa.gov/pdf/nws-nhc-6.pdf
        (See page 15, table 6)
        Anything commencing from there is going to be downhill.

        The plot over the entire 160 years since the 1850s is flat, though. And from the dearth of landfalls over the past years, the decade of 2011-2020 is shaping up to be in a 4-way tie with the 2nd lowest landfall count since then.

        * The 1970s were the lowest count of major hurricane landfalls over that 160 year period.

      I am sad you feel such animosity for people who have lost lives, homes and possessions. You are the type of person that makes me really hope that the Republicans sweep the Mid-Term elections.

      I am a middle of the road political person. I used to like the left when it was Christian based and not full of hate, just slowly working to improve things and change hateful people with love not throwing bricks at them. I see the ANTIFA crowd in Portland and it really makes me dislike the direction the left has taken (on the wrong road!). Your post shows this very cold and calloused value system of a tribal caveman ready to club any who might have different thought process than you.

      Anyway I will supply your cold heart with the data you request. Jeff Masters has a graph of Global Cat 5 storms since 1990.

    ____________________________________________

    I realy dont understand.
    Have we different data?
    My data show clearly an increase of major hurricanes:
    https://tinyurl.com/major-hurricanes-northatlantik

    Can anyone find a fault in this data? Please tell me, I will corrrect it and calculate again.

    • David Appell says:

      What’s the source of your data?

    • bilybob says:

      Fritz Kraut,

      It would be difficult to draw a comparison between satellite, pre-satellite and pre-flight periods (different data collection methods). Since it would be expected that as you go back in time, some major storms would have been missed, especially if they do not make landfall.

      Perhaps a better analysis would be to look at all major hurricanes that do make landfall, but include all of North America not just a particular country or state. One would think these should have been recorded except in rare situations. Though some could argue the older records do not have an accurate category rating.

      For what it is worth, looking just at the satellite period and all major storms, the maximum 5-year and 10-year trailing average occurred in 2005 at 4.4 and 4.0 major storms per year. Those averages are now 2.9 and 3.2. A reduction of 1 hurricane on average. But are higher than the 70’s and 80’s 5/10 year averages.

      • Fritz Kraut says:

        @bilybob
        satellite observations began 1966?
        Here is calculation since 1967: https://tinyurl.com/major-hurricanes-NA
        Increase is even stronger than for the whole period since 1850.

        • bilybob says:

          Yes, there is an increase from the 60’s (3.6 peak 5-year average) to a 1999 – 2008 (4.4 peak 5-year average). The most recent 5-year average is 3.2, but the season is not over. However, even with an additional major storm the average only goes to 3.4, still below the mid 60’s average.

          As far as comparing to the 1850’s, in my opinion, it is a waste of time. Many hurricanes would not have been counted. Even those major hurricanes that did make landfall and are counted may have weakened and recorded as a non-major hurricane.

          As such, focusing on the satellite data era would probably be your best bet in seeing if there is a strong relationship to global temperatures. However, given the averages in the early 60’s is higher than present would suggest the relationship is either very weak or Salvatore is correct and it has been a decade of cooling. Good luck though, the project seems interesting. Perhaps comparing amount of time at certain cat levels may reveal a better relationship.

        • bilybob says:

          One additional thought. There has been discussion on hurricanes as a function of the difference between ocean temperature and atmospheric temperature. This may explain both the early 60’s and 2005 – 2008 averages. Perhaps a more interesting analysis.

      • barry says:

        bilybob,

        One could easily miss a lot of information by using US-landfalling data, as opposed to total Atlantic (and indeed, global) hurricanes.

        • bilybob says:

          Thanks Barry,

          The landfall reference was only for comparing long term trends back to 1850 (apples to apples). So yes, one would miss a lot of information.

          Shorter term though, I agree, using all events would be better. And if possible, duration at each category level of the storm. Though going back to 1950, data may not be detailed enough, so a less robust analysis may have to be performed.

          The averages I posted above is from the data provided by Fritz, all major storms regardless if they make landfall. It shows early 60’s averages higher than current averages, so the relationship of global temp – hurricane intensity may be weak. I looked at both 5 and 10 year averages with similar results.

          I would think a better analysis would be to look at regional ocean temperature/lower troposphere temperature for the hurricane areas. There may be a higher R in the regression analysis. There may also be a relationship to the temperature differential. But I would leave that analysis to the research climate scientist. Maybe some post doc work for one of Roy’s students.

    • barry says:

      Fritz,

      Not so much fault as a questions.

      How do you account for better weather monitoring later in the record? Hurricanes in the past could easily have been undercounted with fewer eyes on the sky (eg, satllite).

      Would you construct the same analysis using only the satellite data (on the same source page)? From 1967.

    Bart,

    We’ve discussed this at length before. Go back and look.
    a. The cold side of the hurricane heat engine is at the top of the troposphere.

    b. The rate of flow of water vapor into the hurricane engine is the gas pedal. Hotter ocean provides more water vapor.

    • Bart says:

      AGW says the top of the troposphere is supposed to warm the fastest, and your internal combustion engine analogy is thoroughly flawed. The bottom line is, you will not get more powerful storms with lower temperature gradients. The “extreme weather” meme is a flailing attempt to sell the product by fear.

      • Nate says:

        Vague assertions with nothing about the specifics of how hurricanes work. Willful ignorance.

        We discussed it before. You never think critically about your posts or learn.

        The temperature of this region is cold -60 C. Suppose it warmed by 1 C to 59C and the ocean warmed from 29C to 29.6 C.

        Then the Carnot efficiency of the engine (TH-TC)/TH, has increased from 89/302 to 88.6/302.6.

        Whoop de doo!

        Meanwhile it is well known that hurricanes are not stable over water < 26 C.

        They have highly nonlinear behavior with temperature of the water.

            Tracks that make it to 40 S are tropical storms.

Cyclone Bola dumped over 900 mm of rain and produced hurricane-force winds in regions of northern New Zealand in March 1988. More recently, Cyclones Fergus and Drena brought torrential rain and storm-force winds to the North Island in December 1996, triggering an exodus of summer tourists from coastal resorts."

            “More recently, Cyclones Fergus and Drena brought torrential rain and storm-force winds to the North Island in December 1996, triggering an exodus of summer tourists from coastal resorts.”

            These events a real and rare. And the North Island is above 40S degrees latitude, isn’t it?

            Though hurricanes are only stable over 26C or more ocean, we know very well that their dissipation is not immediate.

            E.G. Michael traveled 200 mi inland before losing its hurricane status.

            And “You will find all the “data” you want, if you can be bothered looking for it.”

            I already showed you the data, that you must have missed:

            https://earthobservatory.nasa.gov/images/7079/historic-tropical-cyclone-tracks.

            A miniscule fraction of cyclone tracks make it as far south as New Zealand, and those that do are mostly tropical storms.

            These tracks are, globally, quite consistent with the 26C cutoff. In fact, there are no hurricanes forming in South-Eastern Pacific because the water never exceeds 26C there.

            You go on and on that weather is chaotic. All weather events are described in terms of probabilities.

            The probability of a hurricane-strength storm making it to 40 S latitude is teeny tiny. Thats the best anyone can do for you.

            BTW, you mentioned “More recently, Cyclones Fergus and Drena brought torrential rain and storm-force winds to the North Island in December 1996”

    We may have a lull in hurricanes now, but with increased solar activity, they’ll be Baaaack!

  11. Mike Flynn says:

    Neither heat nor water vapour are necessary for high wind speeds. Antarctica is the driest continent, and the coldest.

    “The highest wind speeds recorded in Antarctica were at Dumont d’Urville station in July 1972: 327km/h (199 mph).”

    Maybe you might be worried more about deaths from atmospheric perturbations –

    “The 1972 Iran Blizzard, which caused 4,000 reported deaths, was the deadliest blizzard in recorded history. Dropping as much as 26 feet (7.9 m) of snow, it completely covered 200 villages. After a snowfall lasting nearly a week, an area the size of Wisconsin was entirely buried in snow.”

    If anyone can prove, (as in the mathematical sense, rather than the David Appell climatological pseudoscientific cultist sense), that any changes in frequency or intensity of weather events is not the result of the atmosphere behaving in a chaotic fashion, I would be interested in examining such a proof.

    As the IPCC wrote “The Earth’s atmosphere-ocean dynamics is chaotic: . . . “. I agree.

    Endlessly analysing the outputs of a chaotic system is of no help. It won’t even tell you whether the system is behaving chaotically at any particular time, or even over any particular period. Sad but true.

    No GHE. No AGW theory. Just shared delusion.

    I’m fairly sure you don’t like the following hurricane definition –

    “a wind of force 12 on the Beaufort scale (equal to or exceeding 64 knots or 118 km/h).”

    Maybe you prefer the definition provided by the National Hurricane Center, whose data is used by Dr Spencer. You will note the definition is subject to various conditions and caveats.

    Maybe you could provide a rigorous scientific definition of your own, for the “hurricanes” of which you speak, or is your definition the usual climatological pseudoscientific definition – which is subject to instantaneous change, on the whim of the author?

    In any case, you haven’t given any reason, (let alone proof), for believing that any atmospheric activity is not chaotic and unpredictable in nature. How hard can it be?

    Carry on analysing your datasets. Maybe someone, somewhere, actually cares enough about your opinion to take notice of it. Good luck.

    Thanks for the dataset, Fritz!

    I have played with it and here -> https://workupload.com/file/mvJs7KDb <- is the Bayesian model that considers the data as coming from a negative binomial distribution with an AR1 error structure.

    According to this model the posterior mean increase in Atlantic hurricanes is about 209%

    • Nate says:

      Binomial, I get. Why negative? And what’s AR1?

      • David Appell says:

        “AR” is “autoregressive.” In such a model, one month’s temperature (say) doesn’t depend only on CO2 (say), but also on the temperature of the month before. That is, a warm month is more like to happen after a warm month, and the same for cold. The “1” means one’s calculation only includes the effect of the earlier month, but not the month before that, or that one, etc, and is referred to as “lag-1.”

        This assumption about “autocorrelation” affects the calculation of trend uncertainties. It’s a huge subject, but just considering lag-1 autocorrelation is relatively simple — the number of points N is in essence reduced to an effective number Neff < N.

    “Even more astounding is that out of the top 10 warmest Gulf years since 1860, 7 occurred before 1970, which is before we experienced any significant warming.”

        Are you sure? Why do you say this? I assume you are trying to divert attention away from the fact that there is no GHE, and that reducing the amount of sunlight reaching a thermometer makes it cooler, rather than hotter.

        Keep at it. Keep denying that the IPCC wrote that the prediction of future climate states is not possible!

        Some years have more hurricanes, some less. Some hurricanes are more intense than others. It’s called weather. Good luck with predicting weather any better than a twelve year old child with 30 minutes of training.

  22. Mike Flynn says:

    From that bastion of objective scientific reporting, (only joking, of course), the New York Times –

    “”This is really an amazing event,” said Andrew Dessler, a professor of atmospheric sciences at Texas A&M University. “It came out of nowhere and really intensified rapidly.”

    Michael, he said, did not follow the common behavior of storms, which tend to weaken as they reach the shore because of interaction with the land. “It had the pedal to the metal all the way until it hit the coast,” he said.”

    Unfortunately, Andrew forgot to read the lead in to his remarks, which stated –

    “Little wonder that modern weather modeling got its start in chaos theory, which acknowledges that small changes can lead to enormous effects so that, as one founder of the field put it, the flap of a butterflys wing in Brazil might set off a tornado in Texas.”

    It appears that weather modelling is based on chaos theory, but professors like Andrew profess amazement at the results! Oh dear, Mother Nature remains unconvinced by the firmly held delusional fantasies of people like Andrew Dessler. The hurricane was not particularly “amazing”. Using stupid analogies – “It had the pedal to the metal all the way . . . “. Yeah. Right. No pedal, no metal – just another example of the unpredictably chaotic perturbations of the atmosphere.

    Ignorance is no excuse at law. It seems to be handsomely rewarded in climatological pseudoscience.

        Keep trying – maybe a pointless and irrelevant gotcha might help, do you think?

        So sad, too bad. No GHE, no CAGW theory – just a second rate mob of fumbling bumblers incessantly preaching doom. The Earth’s surface has cooled for four and a half billion years, it seems. The interior is still molten, and still slowly cooling.

        Look at your “data” and calculate the theoretical surface temperature without input from the Sun, if you wish. Surprise, surprise – the nonsensical “GHE difference” has mysteriously vanished!

            Description of the greenhouse effect:

            “IN its normal state, the Earth-atmosphere system absorbs solar radiation and maintains global energy balance by re-radiating this energy to space as infrared or longwave radiation. The intervening atmosphere absorbs and emits the longwave radiation, but as the atmosphere is colder than the surface, it absorbs more energy than it emits upward to space. The energy that escapes to space is significantly smaller than that emitted by the surface. The difference, the energy trapped in the atmosphere, is popularly referred as the greenhouse effect, G.”

    • Rob Mitchell says:

      After working a round of shifts of forecasting wx and sea states in the Gulf of Mexico, the so-called “pedal to the metal” was a 200mb ridge that set up along a line from the Yucatan Channel to the Florida Panhandle last Tuesday. This produced a near ideal upper-air condition for rapid intensification. Hurricane Michael DID NOT come out of nowhere. It was a tropical disturbance that stalled along the east side of the Yucatan Peninsula. When the wind shear diminished last weekend, the disturbance developed into Tropical Storm Michael. The upper level ridge led to its strengthening to a strong CAT 4 before landfall. I seriously doubt Dr. Chris Landsea will find some AGW fingerprint on Hurricane Michael. But leave it up to good ‘ol Dr. Andrew Dessler from my alma mater, he will pin it on human-caused global warming!

  25. Andrew stout says:

    @Nate to paraphrase: ‘ so, the experienced .6c due to climate change hasn’t effected much… ‘. I wanted to nitt pick your charicterization in friendly fashion, assuming by climate change you mean AGW : By my *estimation, looking at UHA , it seems like we’ve been increasing an average of +/- .5c over the past 40 years. Also by my estimation, looking at ( any ) NON Mann proxy records, global temps routinely increase or decrease about 1c over 100 years. So, if we’ve experienced about .6c over 50 years ( the ‘start’ of AGW) we’re not changing at an alarmingly different rate or magnitude from natural variation. So you can suppose some warming is due to AGW, but you can’t attribute most of it to AGW… Its more plausible, imo, to attribute NO warming to AGW , than to attribute ‘alot’ if warming. Call it .1c , If I had to guess, although the reality is also that we’ve changed at a faster rate than 1c/100years in the past, too. Nobody really knows, but based on ledgitimate proxies, and ledgitimate contemporary temp records , nothing seems amiss…imo.

    • David Appell says:

      UAH LT shows warming of 0.5 C in 40 years, but RSS, measuring the same thing, shows 0.75 C of warming over the same time period.

      Surface measurements from several different groups show 0.9-1.0 C of warming since the last 19th century, 80% of which has happened since 1970.

  26. Nate says:

    Some things you say make sense. Others not.

    The 0.6C comes from Roy’s link to temp of gulf water. Take a look.

    “Its more plausible, imo, to attribute NO warming to AGW , than to attribute alot if warming. Call it .1c , If I had to guess”

    Where do you get this? Seems to be just assertion.

    Also surface temps have risen at higher rate than at any time in the record. Show us your record.

  27. Nate says:

    Andrew. Let me add that prior to ~1975, the record showed up or down 0.2 C for previous century. In 1980, it was predicted that the next decades would be warming. This has proven true. The amount, 0.7C, and pattern of warming was close to the predicted.

  28. Andrew stout says:

    @Nate No assertions, but (Admittantly) non ‘authoratative’ analysis ( I’m an Architect, not a professional Scientist). But follow me on this, because I’ve sent several thousand hours as an obsession looking into it: Im looking at the UHA sat records which is why I’m only going back 40 or so years, instead of longer, for a contemporary record to compare against the proxy record. You could throw in Radiosondes, my understanding is that they more closely reflect the findings of the Sattelites than NOAA.Im disregarding NOAA land measurements because by my ( and alot of other Authority’s) estimation, it’s been buggered beyond usefullness , when you look at it’s corrections, smoothed , selected, or fictionalized ‘measurements’. I’ve spent a lot of time validating the existence of the criticisms vs NOAA, and NOAA in my eyes, is left wanting. So I use UHA as a valid Contemporary Record. I’m figuring +/- .5c over the past 40 years as an AVG temp increase, not as a high or a low. Now that we have a couple temporary record of magnitude & rate if change, if you want something to compare that contemporary record against, I choose NOT to use MANN work or work Derrivitive of MANN. I’ve read several books detailing how fraudulent his data is. I’ve read the NAS report detailing how fraudulent it is ( although they try their best to candy coat the posin pill, forgiving him for ‘troubles indicative of new techniques’) Alarmists have flooded the Internet with misdirection, but Mann and the hockey stick has been Utterly discredited. I’ve also read every single IPCC report and it’s clear that ever since AR III (TAR), they’ve been desperate to walk back Mann’s ludicrus assertions. IE, in AR V, the IPCC has rediscovered the Little Ice Age, and Rediscovered the Medieval Warm Period (MWP), although they don’t have the hutzpah to call it that, they call it the ‘Medieval Climate Anomolie’ (MCA). I don’t think they’ve gone so far as to admit to the Roman Warm Period yet, because I suspect, the MCA would look a lot less anolomous if they admit to multiple climate cycles every 1000yrs or so. SO If you jettison Mann-Derrivitive work to suppress climate change in the past, you need another record. I use what Dr Spencer uses, the “Lungvist”(so?) proxy reconstruction. I like it because it provides a certain amount of resolution: it hasn’t been over-smoothed like Mann graphs into non-usefullness. If you simply draw a line at 2 arbitrary points and measure the delta of magnitude over time, you can find easily half a dozen periods or more, over the past 2000 years, where the rate is 1c/100 yrs. In some instances it’s quite greater – about 1c/ 75 yrs I think in one period out of the LIA. That’s not my assertion, that my amateurish analysis of other people’s data, but it isn’t rocket science, it’s an 8th grade Science graphing exercise. Ive done the same exercise with the AR1 (FAR) IPCC proxy reconstruction, and even though it has a low resolution, you can observe the same magnitude of change. It’s obvious why the IPCC erased that geological record from their Reports when they transferred the boogyman from Areosols to Global Warming: a comparison of modern climate change vs the proxy record was nothing remarkable. Hence why Mann had to torture the data to get his discredited Hockey Stick. So, If you use a Non-Mann Proxy, and compare it to a Non-NOAA/GISS contemporary record, you’ll see we’re barely deviated from normal, routine temperature change, in rate it in magnitude. In terms of Absolute temperature, yet again, even in recent history ( say the last 2000 years), we still haven’t matched past highs. I can verify that not just by proxy record but by Anthropological evidence: We’re starting to be able to grow a variety of crops in Greenland we haven’t been able to grow for a thousand years. When we can grow Barley commercially in Greenland, as dug up fossils have demstrated was happening ( and contextually written records reference), then you’ll know we’ve started to match the temperatures of the MWP.

    @Nate Oh and just to close the loop on your Q, I’m assuming the difference between past climate change and today’s climate change is all AGW, by my figures, about .5c observed in 40 years, when I figure it should have been more like .4c in 40 years without industry, per my Lungvist anslysis. But there’s no proof to that. Because of natural varibility It could be more, or a lot less- That’s what I don’t think anybody really knows.

  33. CO2isLife says:

    There is real science backing the Green House Gas Effect, and the IPCC covers none of it. The question needs to be asked, “why are the models so wrong?” If I was going to model Weightloss and the variables I included in the model were # of Pens in home, area of driveway, distance one lives from Florida, I would expect my model to produce results like the IPCC Models. If you don’t include and weight the correct factor, you will never develop an accurate model. Everything regarding CO2 and its impact on global climate must revert back to CO2’s one and only mechanism by which to affect climate change, that being the thermalization of LWIR between 13 and 18 microns. That is the only defined mechanism for CO2, and therefore every observation must be explained in that context. LWIR between 13 and 18 won’t melt ice or warm water, in fact ice emits LWIR of around 10 microns, and very cold ice will emit LWIR between 13 and 18 microns. There is also only a limited amount of LWIR between 13 and 18 microns emitted by the earth and 100% of it is “trapped” by CO2 and H2O by the altitude of 5 feet. More CO2 would simply lower that level slightly towards the surface, but with the convection of the lower atmosphere, that becomes meaningless. Simply use MODTRAN, double CO2 in the atmosphere and measure the impact on the lowest 0.1km of the atmosphere. It has no impact.None, Nada, Zip. Focus on the significant factors. The oceans clearly dominate the climate, the oceans are warming, the oceans aren’t warmed by LWIR between 13 and 18 micron. What is warming the oceans is warming the climate, and what is warming the oceans is more incoming visible light, especially on the blue end of the spectrum. To warm the oceans you need fewer clouds over the oceans or a hotter sun, or both. The IPCC doesn’t focus on those factors so they will never have an accurate model.

        Off you go now. Try an appeal to the authority of the undistinguished mathematician Gavin Schmidt, who seems to be accepted by some as a “climate scientist “. What are his scientific qualifications? None? What a surprise!

        Cheers.

        • David Appell says:

          Gavin Schmidt has a PhD in applied mathematics, and 20 years of doing important work in climate modeling.

          What are your qualifications?

          • Mike Flynn says:

            DA,

            Gavin Schmidt’s work is completely pointless – expensive computer games from a supposed mathematician who said, in 2012 or so, that he saw nothing to convince him that the atmosphere behaved chaotically. I pointed out that the IPCC had expressed a somewhat different view.

            It seems Gavin got a little huffy,

            Gavin also claimed that 2014 was the hottest year ever, based on his calculation of a 38% probability!

            A coin toss gives 50%. 38% means less likely than that.

            This is your authority? On matters of science? More like climatological pseudoscience!

            What have my qualifications got to do with your delusional fantasies? I’m happy to let others decide for themselves whether I’m providing facts or not. I will state that I have never claimed to be a Nobel Laureate, unlike your other presumed authority, the geologist Michael Mann.

            Still no GHE, is there? No AGW theory, either. Just fanatical cultist belief in the non-existent.

            Cheers.

      CO2isLife says:
      There is also only a limited amount of LWIR between 13 and 18 microns emitted by the earth and 100% of it is trapped by CO2 and H2O by the altitude of 5 feet. More CO2 would simply lower that level slightly towards the surface….

      This is a common talking point from deniers, known as the saturation fallacy. They’re wrong.

      It’s easy to see why it’s wrong by noting that the molecules in the atmosphere themselves radiate, up and down and every direction. So, in this case, molecules 5 ft above the surface absorb and then can radiate, in any direction, including upward.

      CO2 isn’t close to being saturated on Earth. It’s not even saturated on Venus.

      • Mike Flynn says:

        DA,

        Who cares? You can’t even define the mythical GHE, can you?

        Make sure your description includes the GHE mechanism responsible for the cooling of the Earth over the last four and a half billion years.

        Complete rubbish – no GHE. No AGW theory. Just an ever diminishing ragtag mob of shrieking GHE cultists.

          Interesting thought. What would the surface temperature be without the sun and with or without an atmosphere.

          We can expect something along the lines of Antarctica I would expect. Where the surface, which continually radiates heat away, would cover something which is warmer as it gets closer to the molten center. I wouldn’t be conducive to life as we know it, but…

          As things are, where I live, piedmont of NC, the ambient temperature about 6 feet underground is around 55 degrees F.

          Warm enough to grow plants and animals.

            Oh dear, gotcha time again is it?

            Before anyone starts thinking you might be less stupid and ignorant than you appear, consider this – does it take more energy to raise the temperature of a gram of water from 99 C to 100 C, or from 0 C to 100 C?

            Now apply the same physics to the Earth. Surprise, surprise!

            No need for a mystical GHE to explain the current surface temperature, any more than it is needed to explain the average temperature of more than 100 C before the first liquid water appeared.

            Now what was the point of your statement, again? Just more irrelevant stupid and ignorant trolling, isn’t that right?

            Cheers.

          • Svante says:

          • Mike Flynn says:

            What is your point?

            Are you practising the mysterious cultist method of disagreeing by not disagreeing? You don’t appear to be disagreeing with anything I said. Diversionary tactics are losing their effectiveness – what is it you are trying to say?

            Are you claiming that the Earth’s surface would be absolute zero in the absence of sunlight? Even you wouldn’t be stupid enough to make that claim, I assume.

            Likewise if you are claiming it takes the same amount of energy to heat a body to a certain temperature regardless of initial temperature.

            These are the sorts of things that would be believed by climatological pseudoscientific cultists – delusional fantasies, unconnected with reality.

            Off you go. Try posting some more diversionary (yet strangely stupid and ignorant) gotchas. Maybe you need more trolling instruction. You are not doing all that well.

            Cheers.

          • Svante says:

            Air cools at night. Does this mean that the earth cools the air as well? Marvellous stuff, this magma of the earth!

            All seems a bit delusional. Heats and cools simultaneously – the average would seem to be zero. No effect at all. Gee, maybe you’re right, after all! Only joking. Increasing the amount of magma between the Sun and a thermometer makes the thermometer colder, not hotter. Not as much energy reaches the thermometer.

            Press on believing in the magical heating abilities of magma.

            Cheerio!

          • Mike Flynn says:

            S,

            You wrote –

            “Air cools at night. Does this mean that the earth cools the air as well?”

            A particularly stupid and ignorant gotcha. Can’t you do any better?

            There are no “cooling” rays. No sources of “negative heating”. Matter loses energy, cooling as it goes, all by itself – in the absence of an external energy source.

            Don’t blame me if your fantasy is not supported by physics – you created it all by yourself. I understand you might wish to stick with climatological pseudo-physics – where cooling is warming, heating is cooling, thermometers get hotter by reducing the amount of energy they absorb, a testable GHE hypothesis exists, and so on.

            So sad, too bad. No GHE, no CO2 heating, and the Earth has cooled over the last four and a half billion years or so.

            Cheers.

      PhilJ…”They need to use a hot ball of magma and gases with a sun that slows its cooling if they ever want to find a model that might work”

  40. More people should be talking about David Dilley. He correctly predicted the 2017 hurricane season in April 2017, when no other hurricane forecaster was predicting a harsh season, amd then a month later in May, 2017, correctly predicted the 2018 season would be just as bad. That’s a gutsy forecast, and he nailed it!

  41. Rob Mitchell says:

    I’ve always noticed that in public forums, liberals brag about their “wealth” more than anybody. And they don’t stop there. Then, they try to tell everybody else what kind of vehicle they should buy, and what kind of electricity to buy to power their homes. They have no respect for “freedom of choice.” Liberals want to use government force to make those decisions for you.

    How do I know this? Well, I happen to be a Tesla owner myself. And I communicate with fellow Tesla owners in the Tesla Forum. It is stunning to me to see how elitist and snobby many Tesla owners are, especially the ones from California. The Tesla leftists want to ban all gasoline powered motor vehicles, and shut down all coal/natural gas power plants. They actually believe solar and wind can replace fossil fueled power plants and meet world-wide energy demand with it.

    Of course this is fantasy world stuff. When I point this out to them, they just cover up their eyes and ears and go “lalalalalalalalalalalala.” Never mind the fact that not everywhere in the world has a lot of wind, or a lot of sun. Facts and the real world mean nothing to them. I have been advocating the growth of Tesla and Battery Electric Vehicles (BEVs) through the free market. Allow the individual to make the decision for him or herself about buying a BEV without any pressure from a government law or regulation. But that’s just not good enough for these liberals. “We don’t have enough time for that,” they say. The earth is heating up, and worldwide catastrophe will result.

    Many of the Tesla liberals are claiming the sea level will rise by 20 feet during this century if we don’t act on climate change. I challenged them about the Arctic sea ice. I told them the Arctic sea ice extent minimum in 2012 was 3,387,000 km2. For the 6 subsequent years in a row, the Arctic sea ice minimum has closed higher than the 2012 minimum. I told them it will close higher for an additional 5 years. I tried to get one of those liberals to challenge me. None of them would. Instead, they ran off with their tails in between their legs, yelping at me by calling me a climate change denier!

      My opinion of Dr. Spencer’s weather related posts is as a counter weight to MSM accounts of weather events.

      If some in the climate change community want to attribute hurricane Michael to global warming then they need to look at a long term trend of hurricanes in this area to determine if there is any noticeable difference.

      Here is one example:

      If some in the climate change community want to attribute hurricane Michael to global warming…

      But that’s an inaccurate – and very typically inaccurate – statement. Neither article attributes the formation of hurricane Michael to global warming.

      See what happened when I specified? Of course that’s not strictly what you meant, but someone else reading your words won’t get it.

      The MSM muddies the waters. So does Roy with articles like the top post.

      In the game of perception management truth is lost.

        You sound like one of the few not bitten by the tribal bug of politics where you must choose a side and support that side rejecting truth in the process.

        You have a point with your post.

        Even if Roy Spencer acts like a counter weight it may still smear a complex picture. Always better to try and stick with the science.

        However, the more terrible the storm, fire or flood, there is a subtle but steady push to link these to climate change to attempt to create an emotional state in the common people (fear and panic) to evoke a change.

        The goal does not seem to use the logical and rational parts of the brain to convince the truth of a matter but more the emotional centers.

        Wouldn’t Roy’s counter weight release his/her readers from this state of emotional fear and panic and move the mind back to the rational logic centers for more intelligent debate over the issue?

      • barry says:

        What’s wrong with just coolly telling the whole truth?

        The “Story of the Week mentioned at skepticalscience is about the recent IPCC announcement and hurricane Michael, and includes this line early in the piece:

        “The fact that both events occurred within a few days of each other is pure coincidence, of course. But it does leave the feeling that Nature just put one or more planetary-scale exclamation marks on the main takeaway from the IPCC report…”

        The nuance in even the sensationalism is obscured with yet more sensationalism. The truth is lost.

        Creating confusion is a tactic that would suit one side of the debate only. That’s the result of infowars.

  43. Mike Roberts says:

    An AP fact check on this said,

    But looking at just major hurricanes that hit the United States is not the right way to gauge their activity. That’s because the U.S. coastline is such a small fraction of the overall Atlantic, Caribbean and Gulf of Mexico, where hurricanes brew and at times hit other countries, scientists said. Looking at just those hurricanes “is like using how much it rained in your region on a given week as a measure of how much it rained across the entire country,” said Texas Tech climate scientist Katharine Hayhoe.

    An Associated Press examination in 2017 of how many major hurricanes formed found that the past 30 years had 90 major hurricanes, an average of three a year from 1988 to 2017. That’s 48 percent more than during the previous 30 years. Scientists use 30-year time periods to take natural cycles into account.

    M,

    “But looking at just major hurricanes that hit the United States is not the right way to gauge their activity.

    Well, yes, it is. Otherwise, you would look at something else, wouldn’t you?

    Typical stupidity from the likes of Borenstein and Hayhoe (amongst others). Journalistic and climatological pseudoscientific claptrap.The AP examination is nonsense. Try looking for the world wide objective data to back up the AP claim. I hesitate (not really) to point out that 95% of the worlds population lives in the 95% of the land mass that is not the USA.

    What about the other 95% of the world? Doesn’t matter? Did the rest of the world have a similar 12 year hurricane hiatus to the US? Does CO2 only work its magic in a completely unpredictable fashion in the US, but is predictable in the rest of the world?

    Complete nonsense.

    No GHE hypothesis. No AGW theory. Nothing. Borenstein and Hayhoe are suffering from some form of mental derangement – similar to that exhibited by Schmidt, Mann, Hansen and the rest of the climatological pseudoscientific cultists.

    All part of the rich tapestry of life, I guess.

    Cheers.

  45. barry says:

    Looking at US-landfalling hurricanes will tell you nothing about the connection between global warming and hurricanes, if any. It’s a small proportion of all hurricanes.

    I’m sure that if some other coastline showed a marked increase in landfalling hurricanes over time, “skeptics” would be making exactly the same point.

  46. Snape says:

    Barry

    I cant even tell why Roys opinion is. Does he believe a warmer ocean wont necessarily produce stronger hurricanes, or is he saying the water off the US coast hasnt been getting warmer?

    Even more astounding is that out of the top 10 warmest Gulf years since 1860, 7 occurred before 1970,……

    I wonder if those years produced strong, landfalling hurricanes? After all, one of the top 10 occurred this year, and produced Michael.

    • Mike Flynn says:

      S,

      His opinion seems to be that this sort of thing –

      “Prof. Michael E. Mann of Penn State told me that Hurricane Michael should be a wake-up call. As should have Katrina, Irene, Sandy, Harvey, Irma, Florence,” he added wryly. “In each of these storms we can see the impact of climate change: Warmer seas means more energy to intensify these storms, more wind damage, bigger storm surge and more coastal flooding.”

      – is just climatological pseudoscientific cultist fearmongering. As are similar comments from similarly delusional persons.

      Dr Spencer might even accept that the atmosphere behaves chaotically, for all I know. Chaos theory might explain the unpredictability of weather, and hence climate. Fools, fanatics, and charlatans claim to be able to foresee the outcomes of chaotic deterministic systems, like the atmosphere.

      My view is that such people are deluded – quite mad. No testable GHE hypothesis, no AGW theory, and the Earth has been cooling for four and a half billion years.

      Seems pretty clear to me. You are free to believe what you like – just don’t expect me to pay for your fantasy.

      Cheers.

    • barry says:

      I think one can get Roy’s general opinion fairly easily.

      He agrees that the world will get a bit warmer with more GHGs in the atmosphere.

      He thinks it very unlikely that this ‘forcing’ will produce change significant enough to warrant making it part of any policy plan at government level, because it would be a waste of govt/taxpayer money, which he sees as a very bad idea.

      He feels strongly enough about this to go to Washington and speak to Congress. Like James Hansen, but with an opposing view, he feels passionately enough to agree to enter the political arena and deliver his view on the science.

      It’s possible his faith plays a role. Apart from a signature on a faith-invested document on climate change, I have no further evidence to fashion a convinced opinion on that.

      And he is not shy about playing the perception game. Whatever drives him, and I don’t believe it is a dispassionate interest in truth, it leads him to create this blog and post a few times a month. Once on a technical update, and several times on various issues, from cautioning skeptics on bad arguments, to countering ‘perception’ issues with more rhetorical argument that duscursive science.

      He is a player, not a neutral party. Plenty of those around the debate.

      • Mike Flynn says:

        b,

        I am the bearer of sad tidings.

        Science doesn’t care whether you are a player, a neutral party, or a climatological pseudoscientific cultist.

        Newton’s Law of universal gravitation, which describes gravity as a force which causes any two bodies to be attracted to each other, with the force proportional to the product of their masses and inversely proportional to the square of the distance between them, doesn’t respond to debate.

        Nor do the Laws of Thermodynamics, Avogadro’s Law, Ohm’s Law or any number of physical laws which totally ignore opinion.

        Perceptify away, Maybe you could come up with a testable GHE hypothesis (unfortunately you would have to describe the GHE in useful terms, first). That would be a great start.

        Just making a lot of noise about the evils of CO2 is not science. So sad, too bad.

        Cheers.

      Interesting? I guess, if you’re interested in weather.

      It’s rained 2 weeks straight in my home town in a month where that doesn’t usually happen. I can’t remember it ever happening.

      Is it meaningful? If I want to know that there’s a bunch of questions to ask.

      The first is – what’s the long-term record say?

      That’s just the first question.

      If I’m interested in something more meaningful that random weather fluctuations.

            If you disagree, please let me know why.

            Why would I prefer 40 years of data to four and a half billion years?

            The GHE experiment, performed by Mother Nature over a four and a half billion years, with a molten ball of rock, surrounded by an atmosphere varying from nearly 100% CO2, to dangerously low levels recently, shows that the mythical GHE has no heating effect whatsoever!

            The result of this experiment has resulted in thousands of degrees of cooling. Cooling. Look down between your feet if you doubt me. No longer molten.

            Away with ye, climatological pseudoscientific cultist! Try science, if you can cope with fact over fantasy.

            May I remember you what you just said:

            “…the extent of ice coverage in the Beaufort Sea is the highest in five years.”

            You are confused.

            You might be referring to Ric, who wrote –

            “So its interesting to see that the extent of ice coverage in the Beaufort Sea is the highest in five years. Is this correct, ren?”

            You also seem to be confused about climate. Climate is the average of weather events taken over an arbitrary period. This is quite meaningless – the weather has already occurred. Averaging does not change the past, nor predict the future. A complete waste of time, but worshipped by climatological pseudoscientific cultists – who knows why?

            You cannot even describe the GHE, let alone proposed a testable GHE hypothesis. You just keep shouting that CO2 is evil, like every other stupid and ignorant cultist predicting the end of the world!

            Still no GHE. No AGW theory. Just an endless procession of nutters – some well meaning, but nutters nevertheless.

    That’s for the Arctic regions. Only. Top graph is all-Arctic, the one’s below are sub-regions.

    This is for the last month. No long-term records on that page, just this past 30 days and the same 30 calendar days for the previous 4 years. So we are looking at weather fluctuation for the same month for the last 5 years – nothing else. This is not a look at long-term climate change (or not).

    Long-term records are available for anyone interested in something more than weather variety.

  53. Rob Mitchell says:

    Global Warming alarmists are always pointing to single weather events as evidence of human-caused global warming. ren is good at countering that game with a series of events that tells a different story.

    Here is an example how the global warming advocates are trying to show that tornadoes are shifting east because of climate change.

    https://apnews.com/9ddb3deeec9a49d6a1349b78f1ca0f03

    In the previous post by Dr. Spencer, he showed how the overall tornado count is way down for 2018. Some folks are trying to show that tornadoes are doing a climate change shift to the east. Hey, has anybody ever thought that the cold month of April might of had something to do with the lack of tornadoes in the usual places?
