UAH Global Temperature Update for September 2020: +0.57 deg. C

October 1st, 2020 by Roy W. Spencer, Ph. D.

The Version 6.0 global average lower tropospheric temperature (LT) anomaly for September, 2020 was +0.57 deg. C, up from from the August, 2020 value of +0.43 deg. C.

The linear warming trend since January, 1979 remains at +0.14 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).

For comparison, the CDAS global surface temperature anomaly for the last 30 days at Weatherbell.com is +0.38 deg. C.

With La Nina in the Pacific now officially started, it will take several months for that surface cooling to be fully realized in the tropospheric temperatures. Typically, La Nina minimum temperatures (and El Nino maximum temperatures) show up around February, March, or April.

Various regional LT departures from the 30-year (1981-2010) average for the last 21 months are:

    so you are saying my bees will die in February or March . I have fed them 40LBs of sugar per hive so i am hopeful, but the last time we had a cold snap in March is it was very bad. :~(

    • Nate says:

      Keep breaking records. A new 5 year record of 0.42 C. This is 0.25 C higher than any previous non-overlapping 5 y period.

      Your bees wont have trouble from the expected 0.2 C global dip of La Nina.

      But they should keep an eye on the arctic and the polar vortex.

    • jane says:

      dr. roy,
      you use fake goverment numbers to draw your lame conclutions.
      Why?

      • Greta says:

        How dare you.

      • jane says:

        climate change is all about the temperture of the oceans. right?
        so what controls the temperture of the oceans? anser, the amount of sunlight geting to them, right. the ambent air temperture mostly does not heat the oceans. so the more junk in the atmustphear the less light/heat gets to the oceans. so in conclution one must assume that burning will cool the planet.

    • jane says:

      u dum fuk, b,s make huney to feed themsleves. u give them sugar and they will get acne and get so fat they cant fly.

  2. U.Pie. says:

    You just feed them on a sunny pre-spring Day when they fly out to empty their bowels. Make sure your bee families are large when they go into winter. The larger size means less energy expenditure thus healthier spring bees

  3. Robert Ingersol says:

    The 13 month running average is once again above the 1998 peak. Last month was the second warmest September on record. 2020 running ahead of 1998, likely to be the second warmest year on record.

    Planet continues to warm.

    • bdgwx says:

      It is sitting at +0.52C right now; just a hair short of the record of +0.53C set in 2016 with raging El Nino.

    • Midas says:

      It is certainly possible. But I suspect the La Nina might have something to say about that.

      • Swenson says:

        M,

        La Nina is a description. It says nothing. You might be hearing imaginary voices.

        • Midas says:

          People who can’t cope with abstraction, including personification, generally lie on the spectrum.

          • Swenson says:

            M,

            Cryptic imaginary voices, too! No wonder you seem confused and lost at times.

          • Midas says:

            Still trying to figure out where on the spectrum you lie.
            That comment of yours was a god indicator, but I need more info – say something else idiotic.

          • Swenson says:

            M,

            A *god indicator*? Do you really worship me?

            Thanks for the encomium, although I make no claim to being a god. Feel free to keep finding god indicators in my words.

          • Midas says:

            The idiocy of someone who pretends not to know what a typo was meant to be.
            Thanks for satisfying my request – you have just pushed yourself to the extreme end of the spectrum.

          • Robert Ingersol says:

            I know an autistic guy. He is a software engineer. He quit working at my company and started his own software engineering company employing only autistic engineers. They are booming. What is your point?

          • Midas says:

            The point is his lack of ability to interact socially in an appropriate way, whether or not he has that as an excuse.

          • Nate says:

            This actually is supposed to be a science blog.

            So unclear why Swenson/Flynn comes here, when he has no interest in science.

            Maybe he is just here to tell us that he has no interest in science.

            Ok, think we got it. Now he can go away.

          • Swenson says:

            Indeed.

            So why are none of the alarmists able to produce that most basic item of science?

            Why is a testable GHE hypothesis conspicuous by its absence?

            And right there is the reason for the alarmists diversionary tactics. Anything to avoid actually accepting the scientific method! Cargo cult science, as Richard Feynman. Assertion after assertion. No testable hypothesis. No theory. Nothing.

          • Midas says:

            Nate
            It looks like he has given up pretending he is not Mike Flynn. He is not even trying any more to avoid using his phrases.

          • Nate says:

            Yep, bad at science, bad at fraud.

          • Swenson says:

            Two deluded nutters, overlooking the obvious. Not as bad as Michael Mann believing he won a Nobe Prize, or Gavin Schmidt believing he was a scientist! But close.

            The whole deluded group believe that CO2 somehow makes thermometers hotter, but hide their testable hypothesis because scientists might want to check it! Ho ho!

            Carry on, nutters. Try another diversion.

          • Midas says:

            Perhaps one day Mikey you’ll get some variety in your comments which will make it harder to determine that you are he and he is you.

          • Dr Roys Emergency Moderation Team says:

            Des, please stop trolling.

          • Swenson says:

            M,

            Who is Mikey? One of your imaginary opponents? Is he like Warnie?

            You a delusional, but you have to create a diversion to avoid the fact that you have no science, just a mindless strong of assertions. Nobody else cares about your fantasies. One non-existent person is as influential as another non-existent person, I suppose.

            Others may prefer to notice that you cant even define the GHE in any useful way!

            Carry on fantasising.

          • Nate says:

            “Who is Mikey?”

            Bad at accepting reality. Not sure what he is actually good at, other than trolling.

          • Nate says:

            “Why is a testable GHE hypothesis conspicuous by its absence?”

            As Im sure the cop told you when u ran thru the red light, ‘ignorance of the law is no excuse’

            Ignorant of the easily accessible facts?? Not our problem, Mike.

          • Midas says:

            An Australian would know Warnie – Mikey was Australian.

          • Dr Roys Emergency Moderation Team says:

            Is there any more reason to care if Swenson used to comment as Mike Flynn than there is to care that you used to comment as Bob, Des, Bond, and Bobdesbond? Mike Flynn isn’t banned, after all – the name posts OK. Seems like a bit of a pointless and hypocritical obsession, Des.

          • Swenson says:

            Nate,

            There is no testable GHE hypothesis, is there? There isnt even a description of the GHE scientific enough to propose a testable GHE hypothesis. You are living in fantasy land!

          • Midas says:

            No reason to care at all. The point is only that he chooses to deny it, out of some kind of shame.

          • Svante says:

            Swenson says:

            There is no testable GHE hypothesis, is there?

            Funny, Mike Flynn asked that exact question 247 times.

            Wikipedia says:
            “The greenhouse effect is the process by which radiation from a planet’s atmosphere warms the planet’s surface to a temperature above what it would be without this atmosphere.”

            https://en.wikipedia.org/wiki/Greenhouse_effect

            Here’s the principle with some random numbers:

            | N | Dwn | In_ | Up_ | Note
            |——————————-
            | 2 | 160 | 320 | 160 | TOA
            | 1 | 320 | 640 | 320 | Mid
            | 0 | 000 | 480 | 480 | Surface

            Notes:
            1) The surface layer has a fixed input of 160 W/m^2.
            2) Each layer absorbs all incoming radiation.
            3) Each layer emits what it receives, i.e. stable temperatures.
            4) There is a 160 W/m^2 heat flow up through each layer.
            5) Without layer 2+3, layer 0 would emit 160 W/m^2 directly to space.
            6) That corresponds to a lower temperature than that which emits 480 W/m^2.

          • Dr Roys Emergency Moderation Team says:

            So how are the temperatures of each layer fixed?

          • Svante says:

            By the fact that each layer has equal input and output.
            Remember that any surplus or deficit means temperature change.

          • Dr Roys Emergency Moderation Team says:

            It’s just that you said there is “heat flow up through each layer”, but also that the layers have “stable temperatures”. Heat flows down a thermal gradient, and acts to reduce that gradient to zero wherever possible (there are obvious exceptions where this is not possible). So I was wondering what stops the warmer lower layers from warming the layers above them? Especially as you say heat is flowing that way. Presumably there is no means by which the temperatures are actually fixed, as in “artificially maintained at the same amount”. So your conception of the GHE appears to suffer from a pretty fundamental contradiction.

            It seems like you have an input of 160 W/m^2 turning itself into 480 W/m^2 by magic.

          • Svante says:

            Dr Roys Emergency Moderation Team says:

            “So I was wondering what stops the warmer lower layers from warming the layers above them?”

            All layers gain and lose the same amount, as you can see.

            For example, layer 1 gets 480 from below, and 160 from above, total input 640 W. It radiates in all directions, 320 up and 320 down. Heat is net energy, so the heat loss is 160 W up, and heat gain is 160 W from below. Net zero means stable temperature.

          • Dr Roys Emergency Moderation Team says:

            “For example, layer 1 gets 480 from below, and 160 from above, total input 640 W.”

            …and how is layer 0 producing 480, in order to provide layer 1 with 480 W!? Why, because it gets 320 from layer 1, and 160 from the sun.

            (Svante won’t see the problem with that).

          • Svante says:

            Yeah, the sfc gets 160 W/m^2 in other frequency bands.

          • bill hunter says:

            Svante your model is a model of non-colliding separated layers. It has no reality in the atmosphere. One might be able to build such a device and either operate it in outerspace or pump all the gases out from between layers to manufacture high R value insulation, but that has zero relevance to our atmosphere because energy exchange from collision of molecules far exceeds energy exchange by radiation in a gas.

            You see this is why Nate calls this the grade-school model but as a grade-school model is misinforming our kids. But that’s the goal right?

          • Dr Roys Emergency Moderation Team says:

            Svante didn’t see the problem. No surprises there.

            Another problem is that the division into three layers is arbitrary. You could divide the atmosphere up into a potentially near-infinite number of layers, and then by applying the same logic and the same initial 160 W input the surface layer ends up ridiculously high in temperature.

          • Svante says:

            You both misunderstand.
            It’s not a model of the atmosphere.
            It shows how simple symmetric absorbs and emission creates a greenhouse effect.

            NOTE: the atmosphere is not exactly like a greenhouse either.

          • Dr Roys Emergency Moderation Team says:

            I didn’t describe it as a model of anything, Svante. My criticisms still stand.

          • Svante says:

            Yes, the division in three layers is arbitrary.
            In reality it is different for different frequencies.
            In reality the atmospheric window has zero layers.
            The real atmosphere corresponds to less than one layer.
            In fact it has no distinct layers at all.

            You need a Line-By-Line Radiative Transfer Model to calculate it well.

            Can you understand the principle I described?

          • Dr Roys Emergency Moderation Team says:

            Of course, that’s how I know it’s wrong.

          • Svante says:

            For comparison, here is the situation without GHGs:

            | N | Dwn | In | Up | Note
            | 0 | 000 | 160 | 160 | Surface

            As you understand, 160 W/m^2 corresponds to a lower temperature than the 480 W/m^2 (hypothetical) GHG example.

            The numbers are random of course, I’m just illustrating the principle.

          • Nate says:

            ‘Presumably there is no means by which the temperatures are actually fixed, as in ‘artificially maintained at the same amount’. So your conception of the GHE appears to suffer from a pretty fundamental contradiction.’

            Oh no, not that rot again!

            There seems to be no hope that DREMT will ever comprehend heat transfer basics.

            DREMT just cannot wrap his brain around this ordinary everyday occurrence, when a heated system reaches a steady-state with a steady heat flow and a steady gradient in temperature.

          • Dr Roys Emergency Moderation Team says:

            Svante, I already explained why you are wrong.

          • Nate says:

            Sure you did, but as usual with the Dunning Kruger afflicted, you have way overestimated your understanding of the issue.

            =====================================

            Nate there is no steady heat transfer gradient in the atmosphere. You are just imagining there is one.

            Most of the heat in the atmosphere transfers by an unevenly distributed water in the atmosphere and it does so with the bulk of the heat in the atmosphere being delivered via the higher heat capacity of water combined with latent heat. Anybody trying to stress a steady gradient to that needs their head examined. Radiation is a minor player in that symphony.

            You are just parroting the hypothesis you sent that duplicate historic climate.

            It’s a major player as you get nearer the top.

          • bill hunter says:

            Indeed Svante. And if you ever had the pleasure of flying propeller passenger aircraft to any extent you would quickly learn that near the top is the most turbulent zone in the atmosphere. Jets are much better as they fly mostly in the stratosphere.

            “Nate there is no steady heat transfer gradient in the atmosphere. You are just imagining there is one.”

            For the 47th time, Bill claims I said something I didnt say.

            He just cannot bring himself to honestly debate the things that people actually say.

            I was claiming that steady state gradients are a common phenomenon. The atmosphere has gradients which vary over time with weather. Overall it has a rel steady average gradient.

            You guys just cant appreciate the big picture, and you focus on the rust on the hub caps.

          • Nate says:

            The point is that the simple models were never intended to capture every detail of the atmosphere, with its weather and overall general circulation.

            They are only intended to explain one aspect, the basic mechanism of the GHE.

            No point to complain that they fail to do what they were never intended to do.

          • Dr Roys Emergency Moderation Team says:

            Bill, note that what I actually said was:

            "Heat flows down a thermal gradient, and acts to reduce that gradient to zero wherever possible (there are obvious exceptions where this is not possible)."

            By acknowledging that there are "obvious exceptions where this is not possible", I clearly accept that there are everyday situations where you have steady temperature gradients and steady heat flow. Nate always deliberately misrepresents others, which is one of the reasons why I no longer bother responding to him.

            Well maybe Nate you should read the reference you sent to support your claim that the the greenhouse effect physics had been tested. And here it appears you are both denying you said it and claiming some kind of mean steady state at the very same time.

            Typical warmist double speak!!

            ====================

            My take on the topic is that the paper submitted by Nate from the 1960’s by Manabe and Wetherald assumes a rigid lapse rate mean value of some sort in the troposphere as a whole in order for a hypothesized forcing at TOA to reach back to the surface.

            My take on that is if true a boiling pot of water would merely steam rapidly rather than boil. Treating a gas or a liquid for that matter like rigid insulation is the controversy in the current viewpoint of the atmosphere acting like a blanket.

            Thus simply positing that while it isn’t rigid it is rigid in the mean sense seems a bridge too far with the current state of science.

            Certainly I would love to be illuminated on the topic further but Nate appears way too ignorant of the facts to accomplish that. I certainly don’t expect it come from another skeptic on the basis that its not possible to disprove or dispute a theory not clearly stated.

          • bill hunter says:

            Nate says:

            The point is that the simple models were never intended to capture every detail of the atmosphere, with its weather and overall general circulation.

            They are only intended to explain one aspect, the basic mechanism of the GHE.

            No point to complain that they fail to do what they were never intended to do.

            ===========================================

            You are actually correct there Nate. But it raises the question why you believe it then. Even M&W in the study you sent in support specified that the steady lapse rate gradient was an ”assumption”.

            Which of course leaves us without any proven theory of how CO2 controls the climate.

          • Svante says:

            Yes, the GHE depends on the lapse rate, which is determined by convection mostly.

          • Svante says:

            bill hunter says:
            “if you ever had the pleasure of flying propeller passenger aircraft to any extent you would quickly learn that near the top is the most turbulent zone in the atmosphere.”

            I flew gliders and the turbulence often disappeared a few hundred meters above the surface.

          • Nate says:

            “Even M&W in the study you sent in support specified that the steady lapse rate gradient was an ‘assumption’.”

            Yes sure. Which was an adequate model to understand why the lapse rate has the average value it does.

            “Which of course leaves us without any proven theory of how CO2 controls the climate.”

            No. Strawman. MW not intended to do all that. The global circulation models go way beyond MW and see AGW in action.

            audit time is expensive. I am not going to search for whats not there. Its up to the proponents of a theory to provide evidence of its truth. In the audit game you try to ask folks that either claim to know or should know. If they don’t have an answer its time to figure out how much more you are going to charge them to come up with a solution.

            So if you guys want to pony up on that, the order desk is open.

            but I figure the two of you are just frauds claiming to know and either too stupid due to the Dunning Kruger effect or you are running a con. Because if its not a con then you definitely would like to let me know. . . .basic human nature.

            …and how is layer 0 producing 480, in order to provide layer 1 with 480 W!? Why, because it gets 320 from layer 1, and 160 from the sun.

            This is perpetuum mobile, Svante.

            Exactly out there in the world parroting grade school climate models as if the technology actually ever even once worked like that in a gas. You might even ask why anybody believes that for even one tenth of a second. And the answer is because the atmosphere has a lapse rate. It doesn’t have anything at all to do with forcing anything.

            Svante, your layer 1 has an input that comes from your layer 0. Where does the energy come from for this output from layer 0? Largely, from layer 1! Most people will be able to see through this, especially when I spell it out for them like that. I don’t need you to admit you are wrong, I know you never will. So, repetition is the best course of action.

            5) Without layer 2+3, layer 0 would emit 160 W/m^2 to space.

            It is obvious to me that politics is playing far too big of a role at his point in time. It is being divisive rather than inclusive. The very concept of academic freedom is a license to be a weirdo. Its important in academic circles to NOT adopt the ‘party line’. I doubt that climate science currently further astray from that standard than anytime in US history anyway.

            Climate science was not a political issue a couple of decades ago, and it’s only a major problem in the US, Australia, Brasil, Indonesia and Arabia.

          • bill hunter says:

            thats just wishful political thinking on your part Svante. What you have in evidence is continued warming and a major 5 year ENSO event as an explanation for it.

            However, thats been an injection of hope into the warmist community. But what has been happening as science advances has been a relentless increase in knowledge of natural variation that accounts for a goodly portion of the longer term warming.

            Further in the category of convincing educated minds no significant inroads have been had on turning experts around on the matter. We can expect the numbers to remain highly in favor of the warmest point of view for really no other reason that its warmism that speaks to a bright future for people in the field, especially the younger ones. . . .and as a model for attracting new talent into the field. But those kinds of numbers mean absolutely nothing one way or the other. They vary based upon stuff that has nothing to do with the actual science surrounding climate change.

            PS Which ENSO index has been positive for 5 years???

            ============================================

            The index doesn’t need to remain positive for the entire 5 years and I don’t think it ever has. But NWS talks about such phases where El Nino dominates. And the domination of El Ninos is known to be associated with the warm phase of the PDO.

            Look at 1982-1987 for example. Similar to what we are going through now.

            Also the 1930’s and 40’s were likely an extended El Nino dominate period. . . .with more evidence of that provided by climate models not otherwise being able to duplicate that. You have to know what causes it to duplicate it.

            Further that period casts doubt on most of the recent warming as it could be just another reoccurance of that either in whole or major part.

            You guys basically reject that by belonging to a religious sect that doesn’t recognize itself as being one. If so time will tell.

            So you take the easy way out. It’s wrong because of politics.

            To see the evidence against this, look no further than the classic papers and reports on the GHE and AGW from before it became politicized.

            Arrhenius 1896
            Callendar 1938.
            Suess and Revelle 1959
            Manabe and Wetherald 1967
            Keeling, 1976
            Charney Report 1979
            Hansen 1981

            These papers establish the theory behind AGW, and make the predictions of future warming, that indeed happened.

            You can learn a lot from these papers, with out fear that they have been politicized.

          • bill hunter says:

            All any of those papers do Nate is state a theory based upon assumptions about how the climate works. Revelle in particular emphasized that it was premature to conclude anything. He held the theory but as a respectable scientist he knew his theory needed confirmation.

          • Nate says:

            The Charney report, FYI, was headed by Charney, who was chiefly responsible for developing numerical weather prediction. The report’s predictions have held up well.

            Nice ENSO image there bill.
            So global temperature levelled off in 1980, and then went down?

          • Nate says:

            “Revelle in particular emphasized that it was premature to conclude anything.”

            Roger Revelle died in 1991. I have no problem with his statement at that time.

            The same article you are referring to stated: “there is every expectation that scientific understanding will be substantially improved within the next decade”

            And that did happen. The predicted warming and other fingerprints of AGW indeed appeared, and continued to develop over the decade, and two more decades after his death.

            So nice try, but another big red herring.

            An update would be spinning on its head and quashing a whole lot of political propaganda in favor of immediate action. . . .so it hasn’t been updated. Not to talk about the backlash that would unleash and how that would harm the democrat science constituency in its never ending quest for more fuel to power their progress.

            Mark Serreze hasn’t updated his predictions about the arctic.

            James Hansen hasn’t been doing anything but walking back his prediction about the West side highway being submerged about this time.

            Revelle never made a prediction,

            Keeling only talked about CO2 increasing in the atmosphere,

            The Charney Commission morphed into the IPCC (report above),

            Callendar is long dead and made a lowend of the range prediction below the action window,

            and carbon credit investors are screaming for relief.

            So nice try, but another big red herring.

            Do you guys have anything thats not a strawman or a red herring?
            =========================================

            So what does the above leave? Oh yes a 1967 paper on essentially system feedbacks.

            My professional opinion on that is likely the high bidders were either pessimists or felt a great need to clearly separate themselves from what climate has been seen to do in recent global history naturally without a need for emissions.

            And politicians whose constituencies are screaming for moola, aren’t apt to do a better job sending that by conceding even to the level estimated by M&W, or even lower to get to Callendar, or even lower than that to embrace actual observations.

          • Nate says:

            Well Bill,

            My response with the list of earlier works was responding to you blaming politics for AGW science.

            Now right on que, you will move the goal posts, and claim many of these people are dead and yada yada.

            Yes. That happens, people die. But their science lives on. And was proven prescient. Even if you deny it.

            The Charney report was not connected to the IPCC.

            Charney was a pioneer of weather and climate modeling. He and the other authors of the report knew what they were talking about. None of today’s politicization was involved.

          • bill hunter says:

            Nate my only comment is you have not made a science case that the warming we have seen is caused by CO2. If the science was uncertain 1991 what happened to change that? The climate sort of warmed for 3 decades?

          • Dr Roys Emergency Moderation Team says:

            #9

            The concept, as you presented it, has been debunked. No diversions will be followed.

            This message will be repeated until it is the last word on this sub-thread.

          • Nate says:

            ” If the science was uncertain 1991 what happened to change that? ”

            As we discussed dozens of times, the predictions in the papers proved quite accurate.

            So lets see, the 1981 Hansen paper predicted the warming would rise up out of the climate noise of the previous century

            In 1990, the global temperature had slightly and briefly exceeded the climate noise of previous century as you can see in red curve.

            Revelle would have been correctly cautious in interpreting this.

            But you can see in the Green curve, by today, the upward trend was way out of the noise of the previous century. And Revelle would have been impressed by the accuracy of the predicted magnitude of the warming in eg the Hansen 1981 paper, and by the arctic amplification, sea ice decline, and W. Antarctica warming that were all predicted.

            https://www.woodfortrees.org/plot/gistemp/from:1880/to:1990/mean:24/plot/gistemp/from:1989/to/mean:24

            He would have said the models need to improve, but the AGW effect has largely agreed with predictions, because ultimately he was a scientist not a denier.

            =============================

            Even if that were true Nate, and you claim to be a scientist, statistical certainty doesn’t arise unless you can change the controlling variable and get a reaction from the system. An essentially linear or logarithmic rise in a variable compared to a similar but not exact rise in the result doesn’t increase certainty.

            Dr. Richard Lindzen gets that but obviously everybody on a payroll surrounding the modeling exercise including all the extra dollars to analyze mitigation and avoidance strategies is definitely not going let that absorb into the their skull.

            And some people are stupid to talk about in public. LMAO!
            Once again correlation is not causation. Thats just another form of fallacy exactly like curve fitting. . . .call it straightline fitting rather than curve fitting.

          • bill hunter says:

            The only reason nobody is listening to Lindzen is they don’t have another option. And politics isn’t going to let it die. The most important paradigm in politics is ”never waste a crisis”

            “statistical certainty doesn’t arise unless you can change the controlling variable and get a reaction from the system. An essentially linear or logarithmic rise in a variable compared to a similar but not exact rise in the result doesn’t increase certainty.”

            With that viewpoint, Bill, there can never be an adequate test of the theory, since we don’t have alternative Earths.

            But that means all observational sciences, like Astronomy, or Geology, or Zoology are not science?

            But clearly they are.

            With Climate Science, we don’t have a control Earth. But we have models that can include all known natural forcings, and have added anthro carbon or don’t.

            For the past century we can see that the natural forcings alone are not sufficient. We can test models against past history and make predictions, as Hansen’s 1981 model did, and then see how they performed.

            This modeling, together with continued observation, is the best we can do. And we have to base our choices on that.

            Just as if there were an asteroid headed our way in 25 y. What choice would we have other than to use known physics and computer models to predict what will happen, to make decisions about what to do.

            Of course we have ways of testing the theory. You don’t need duplicates of the earth to do it.

            I sense there is a lab experiment that can do it. Not a cheap one though more like the Cern experiment. But I don’t think you have to build a whole Cern site. I imagine with a little ingenuity it could be done in an artificial environment.

            But thats certainly not the only option. We have a few planets in our solar system. I would start there. hmmm, I think some folks have already been going off in those directions.

            =======================
            Hmmm, I think we have tested all those theories Nate in the lab. Computers are used then to quickly do the calculations we already know how to do.

            I know how it works because I work in an environment with uncertain variables but some clearly known facts. Each new project is the first try. Action is taken and usually within a few years we know if we have a correlatable response. Its like actually stopping or slowing the emissions to see the effect.

            So in essence we are running an experiment. It gets pretty controversial though when you want to run an experiment on the entirety of humanity. Kind of sounds like a lamarckian Soviet five year plan or a German-wide experiment in Francis Galton eugenics. Hmmm, Francis Galton may have been one of the world’s first climate scientists.

            bill hunter says: “Its like actually stopping or slowing the emissions to see the effect.”.

            It happens every year with the seasons. Feldman et. al measured the varying back radiation. The idea that it’s not thermalized at the surface is simply preposterous.

            Thats just an emotional outburst Svante. Doesn’t even approach being scientific evidence that it does.

          • bill hunter says:

            Further the seasonal test isn’t one of emissions. Its a test of orbital variation and a change in primary hemisphere exposed to the sun. Thats one of the reason even seasonal weather is disqualified from being called climate.

          • Nate says:

            “I sense there is a lab experiment that can do it. Not a cheap one though more like the Cern experiment.”

            Yes, good idea, but those have been already done starting 150 y ago with IR properties of CO2. And then in the atmosphere, as discussed in Arrhenius 1896.

            “But thats certainly not the only option. We have a few planets in our solar system. I would start there. ”

            Yep another good idea that’s been done, as described by eg Hansen who started with Venus and Mars.

            You are full of good ways of testing things in the lab, but other people had these ideas long ago too, and even done them!

            As far as better quantifying feedbacks in the Earth system, computer modeling and testing with observations is the way to go.

            But getting a better understanding of the feedbacks is not going to make AGW go away.

            Even Lindzen knows that.

          • bill hunter says:

            Well with especially the stuff that Svante has been posting today about AGW backdating to God knows when, who would want to get rid of AGW?

            Don’t be shy about actually making a case for the idea that CO2 is the responsible party for the greenhouse effect.

            A nice study of a multiple planet correlation would certainly help convince folks. If such a beast exists I would like to read it.

            A computer model one could run on a PC that one could drop real parameters in like how to turn the moon into a motorized indy car site in a farm belt, with the resultant CO2 emissions feeding farm plants in the infield could be inspiring for a whole new generation of space explorers. Heck they could kill several birds with one stone. race their butts off, feed plants, plants produce oxygen, oxygen and the fruits of the plants support more race car drivers. . . .the only limits are ones imagination. . . .and just think doing that would divert fossil fuels to the moon, raise the price of the fossil fuels, reduce use on earth and everybody would be happy without having to dream up some way to punish people.

            With all the billions we pour into this one would like to think that something positive would result.

            Artificially created greenhouse effects on the various planets would be so cool! Gee it would open the window maybe to imagining turning the red planet into a giant farm and converting it to the green planet. Heck would even be a kick and great training vehicle for kids that want to grow up and become arctic farmers.

            No I wasn’t talking about a one planet mathematical model. I was talking about a scale model planet artificially created ala the Cern project that shows that cosmic rays may play an important role in climate.

            Seems from a raw progress point of view the cosmic ray theory is out in front having actually produced evidence of the desired effect in an artificial environment.

            The CO2 folks need to get their behinds in gear and catch up. Perhaps the model project is too challenging but there is always the space program as described above.

            Well you were doing well with lab testing of IR properties of gases, etc, but now you have gone seriously off the rails.

            You think a ‘scale model planet’ would be useful in understanding cloud feedbacks, albedo feedbacks, changes to circulation patterns, ocean dynamics on the real Earth?

            Better than a computer models??

            OK.

            You believe size doesnt matter? You may want to quiz some lady friends about that.

            Just one example may put this idea to rest. A few decades ago, computer models were finally able to reproduce the actual general circulation pattern of the Earth using first principles, with the various latitude bands and air flow patterns.

            The Coriolis effect is just one effect for which ‘size matters’ a great deal. Eg contrary to popular belief, it doesnt happen in a toilet.

            So no ‘scale model’ of the Earth will be able to reproduce the general circulation pattern, cloud or albedo feedbacks, etc anytime soon.

            Seriously? Come on Nate you must be pretty ignorant about the role of modeling. When someone wants to do a model of gravity one doesn’t need a whole world to do it to model everything effected by gravity on the face of the earth.

            I am talking about a greenhouse gas model that produces a hotter than source greenhouse effect using the first principles used in the climate models. You don’t need clouds and oceans or circulation patterns to do that. I am certainly not talking about producing a climate/weather model out of a modeling exercise just suggesting it might be a good idea to understand clearly the mechanics of a greenhouse gas effect.

            We used to have scientists that actually did experiments. Did all those imaginative people just die off and science has turned into a virtual reality study where we can arm the cartoon participants with ray guns?

            Boy are you ever naive. Have you ever had a real world job developing and testing computer models? Sure doesn’t sound like it. An asteroid? Yeah we probably have enough lab science to know what an asteroid up to X size will do as we have information on megaton bombs. A lot bigger than that and models aren’t going to help a hoot. One could pull out a bar napkin and lay out a straight up extrapolation if you understand the math for a tested bomb. If you want to lay it out geographically then obvious a GIS software package would be useful.

            But what is the plan here for avoidance, map out all the impacts for every location on earth? What you need to know is how to stop the thing from hitting a vulnerable spot. Blow it up, change its path. No doubt a mission to do that would rely on computers. Plus every thing that goes into a model is known factual stuff that wasn’t learned by a computer but learned by people and translated into the computer.

            Yes you can learn from computer modeling. Maybe after a few devastating asteroid hits we might actually be able to use a computer to figure out how to change our strategy.

            Nate do you actually have a job as a physicist? Are you retired? Did you retire before the computer modeling age began?

            It should be obvious that the asteroid impacts we have to worry about are the ones much bigger than any bomb we have tested in the atmosphere!

            ” A lot bigger than that and models arent going to help a hoot.”

            Well sorry but thats all we’ve got when it comes to asteroids that produce possibly global effects.

            They can ONLY be modeled on a computer.

            Thankfully we’ve learned from climate modeling and some data from past asteroid events.

            Maybe you should learn what they have learned Nate. You have it all wrong. Yes you can look up in the sky and measure a radiant field up there. But to understand what it is you actually have to work with it and do stuff with it and then measure the results. I am fairly convinced you don’t even understand how its currently believed to work and provide a forcing.

            A hint is that yes the atmosphere MUST have an insulating value but it is not the kindergarten model.

            Get into a lab environment explore all that stuff and when you come out tell me what you found.

Computer models able to routinely fit a problem are good. Computer models of essentially linear warming in its first test run as are all the 1976 technology models keep failing and the operators keep denying why and figure it must be subregional cloud processes that are screwing them up.

            Nope, I have said uncertainty still exists. Uncertainty that even the IPCC is not recognizing. Such is possible in worlds where all the funding decisions are made by the inculcated. Academic freedom is supposed to remedy that, but even academic freedom gets hijacked in the same manner general freedom does and for the exact same reasons. If that weren’t the case, I wouldn’t have a job quite frankly.

            =====================

            It still is. Fact is politically speaking all anybody wants to recognize are positive feedbacks. Putting on the racehorse blinders and racing to the big prize at the end of the rainbow entails not getting dallied by blind alleys. People who go down blind alleys get mugged, delayed, and seldom finish first.

            but I am a weird bird. I don’t care about fame and fortune. Alleys are my place of doing business and it actually is a far more interesting place than joining the rat race.

            So yes it is about feedback. Here I am talking pre-surface thermalization feedback. Even incoming solar has to deal with it, its strange though how many morons believe IR doesn’t.

            I will admit to a strong appeal to the idea but it seems like one hardly anybody is looking at in detail. They just buy automatically into the traffic jam idea of heat leaving the atmosphere. I will even go and concede its possible but with quite a few years of dealing with heat energy, experimenting with it, and building solutions for it. . . .there is probably a better way to explain it. After all the amount of heat being radiated from the top of the troposphere by CO2 is a pittance.

            And speaking of traffic jams, the kindergarten model leaves out the carpool lanes.

            And why when it comes to assigning a percentage of uncertainty regarding a process you can only include the uncertainty you acknowledge.

            I agree it’s a thorny issue and let me tell you I have untangled a lot of thorny issues. Unable to produce forcing in a lab it’s assumed to suddenly arise at TOA not because of forcing but because of a lack of emission capability of CO2.

            Now thats an instantaneous moment when the pea gets dropped under a different shell. The argument has been made and at the last second it turned on its head. I agree it’s puzzling. But at TOA there are already hardly any CO2 emissions to further block. The kindergarten model explains why.

            But the kindergarten model as far as CO2 is concerned is near saturation, it’s a dead horse that for time immemorial hasn’t won a race. . . .always losing by a 100 lengths to a horse named Convection.

            so a new argument just HAS to be formulated to explain climate change. Enter the multiple layer argument where the kindergarten model actually starts influencing the temperature of atmosphere layers when it is completely incapable of doing anywhere in the stratosphere. So it just has to be happening in the troposphere. Ignore its impotence and lets pretend it is going to create an extension of the height of the troposphere lapse rate which it must do to do its dirty work. Yet that is what the tropopause is it’s a place where troposphere height varies on a diurnal basis.
            What you are seeing is a depiction of the mean troposphere height as it varies through various insolation and weather conditions. So imagining CO2 extending the troposphere seems to be something right out of the ‘Twilight Zone’. An atmosphere a place of amazing apparitions, where the imaginations of the Rod Serlings of the world can think up things to control the world.

            And of course the answer given to that problem is the models have figured it out. So now you are in my bailiwick not yours. I can tell you just as Drs. Lindzen, Happer, Curry, Akasofu, Cristy, Spencer, and many others that just isn’t so.

            Might as well get a tattoo for your forehead,

            Science is Leftist, therefore it must be wrong!

            ===============================================

            LMAO! ‘Science’ is as political as any other large group of people and their left or right leanings are for the same reasons as other groups of people.

            Indeed there is leftist science and there is rightist science, or at least it’s claimed to be science. It’s more than highly questionable that that either of those sciences is really science when real science as once said of by Will Happer is something very easy to explain to an eager classroom of bright students.

            The only thing political going on in this thread is your underhanded and false suggestion that science is of one mind on this topic.

            And we know that scientists being mostly funded by government and we know government workers are one of the most politically-oriented groups in America. that has to do with a lot of reasons, not the least of which is being funded by tax dollars.

            So left leaning science is a reality. It’s right in front of your face but you are a denier of that real science.

            more on that later.

            “And we know that scientists being mostly funded by government and we know government workers are one of the most politically-oriented groups in America. that has to”

            This is you being ignorant about science and its funding, and substituting your political ideology, and conspiratorial thinking for facts and evidence..

            Funding from the govt for science is apolitical. After all, the govt is us, not a party.

            I recieved several govt grants to do science. The only requirements i
            are that it be high quality, relevant and useful, and meet the standards of science. And a track record of accomplishment in the field of study is essential.

          • bill hunter says:

            There you go denying science right off the top Nate.

            Lots of good studies on the topic here is the first one that comes up in a google search. https://www.jamesgmartin.center/2019/08/did-you-know-democrats-dominate-professorships/

            I mean they could have been independents right?

            I am not talking about blatant bias but the bias is exacted at every level including what you can get a grant for. I live in a world of grants much of my work has been supported by grants. As a grant applier it was well known for at least a decade that if you didn’t have global warming or climate change in your grant you weren’t likely to get funded. Just the terms themselves are politically charged and have nothing to do with relevant science issues that might or might not conclude global warming or climate change was occurring. Those are words invented by activists for the specific objective of moving the political needle. They operate on the assumption that climate is changing rather than varying as it always has. And you sit there red faced and claim otherwise. Shame on you.

          • Nate says:

            Given that one party is the deny science party, which party are scientists likely to be members of?

            German scientists were also less likely to be in the Nazi party, who decided that 20th century physics was ‘Jewish physics’.

            Notice the similarity to todays Trumpists who think science is ‘leftist’.

            Sorry, science is science, there is no ‘leftist’ science, at least not in the physical sciences.

            What about the science of when a fetus become a human being? Do we have any science about that? Seems like a topic for biological sciences. And we see a lot of politics in biological sciences. Extinction of polar bears is one that comes to mind.

            Uh impacts of climate change on wild populations of animals another.

            These fields are absolutely ridden with politics where science really ceases being science and becomes advocacy where you put your preferred PhD up on the court dias; in a seat in Congress to testify; and in public dialogue.

            You must have your head drilled deep deep deep in the sand to not have noticed that.

            Is there any politics going on about evolution? I know there was back almost a century ago.

            Is aids a virus? I have no idea I haven’t paid any attention to the topic. Haven’t seen any need to. been monogamous for uh 40 years.

            hydroxychloroquine we know is not a cure for covid so I don’t know what you mean about effective against covid. What we do know about hydroxychloroquine is that it acts similar to a nutritional supplement and strengthens our bodies to be better prepared for Covid. It works for a rather wide range of ailments and even thousands of doctors swear by it as a way of building resistance to the disease even after contracting it. I took it in in 1965 as preparation for an assignment to Vietnam.

            Looking around at 74 year old men who have taken it. . . .can’t find any reason to believe it doesn’t help.

            Well not sure but it does appear that if you were a middling scientist in one of those fields you might have rushed for opportunities in climate science that was experiencing an exponential increase in funding for quite a few years. If you were really good in your field you probably stayed put.

            If you think science can decide if an x weeks old fetus is not a ‘human’ but x+ 1 weeks fetus is a ‘human’, you must be really naive.

            That is all about religion and belief, not science.

            And really, evolution? In biology and medicine, evolution is long since proven science and essential to those fields.

            Evolution has only ever been politicized by people from the religious right.

            I said: that it was part of DT preparation and treatment for Covid. So what do you think you are? Some kind of magician? I said thousands of doctors continue to use hydroxychloroquine and DT got Covid and was symptomatic free in what like 3 or 4 days?
            and he is in at least 2 vulnerable groups, overweight and over 70.

            Democrats keep harping ”hydroxychloroquine is not effective for Covid.” amd that taking hydroxychloroquine is not safe.

            Why do they actually think they are doctors and they want to limit people’s choices and they would prefer people to die just in order to prevent DT from getting reelected?

            You do realize that warming could be related to something else don’t you. Check with an expert Nate. Dr. Akasofu would be a good start. Check with a democrat and it can’t be anything but what they want it to be.

            “The rise in global average temperature over the last century has halted since roughly the year 2000, despite the fact that the release of CO2 into the atmosphere is still increasing.”

            Warming is back on track and Akasofu is 89 years old, so it’s time to look elsewhere for a better answer.

            Exactly. The observations, the data are what came after. They agreed with the prior predictions. The magnitude of the rise and the spatial pattern. Generally in science that is considered good evidence.

            Not the last word.

            Yep! We took 500 years to plumb the depths of the LIA, we should take maybe as long to climb out of it.

            Some hope that though it might not take as long if you look at ice core records recoveries from glacial periods take a lot less time than the plunge into the glacial takes. It would be good to have a hypothesis that produces that pattern, but alas we don’t.

          • bill hunter says:

            First we have no idea what the range of natural variability is.

            Ice core noise suggests that 3 degrees isn’t out of range.
            Its been a good deal less than 3 degrees in the current climb out of the LIA.

            Svante you are such a science illiterate its not even funny. Took me about 2 minutes to figure out what you said above is false.

            This data base maybe as you say it is up to sometime between 500ad and 1500ad, showing the MWP as cooler than the holocene maximum. I haven’t seen much disagreement on that proposition.

            Where the controversy jumps into this study is then the 500-1500 mean was matched to Michael Mann’s hockey stick in the 2kpages recreation of it with Mann as an author.

            Here is the defining statement in the methods section:
            ”The composites were registered to the temperature scale (left-side x-axis) by aligning the 500 to 1500 CE mean of the composite with the mean of the global temperature reconstruction from the same interval in the PAGES 2k Consortium571 multi-method median reconstruction. The variance of the Holocene temperature composites (all based on records in units of °C) were not scaled.”

            Check out Figure 8 how they spliced this to the temperature record. The bulk of the proxies end about a thousand years ago. The one proxy comprising 43 records extends to about 250 years ago and shows the LIA to be hotter than the MWP. Then Michael Mann takes over from there and we all already know about that.

            Fooled again eh Svante? All it amounts to is a samo samo Michael Mann hockey stick and of the numbers you they tossing around doesn’t even touch much less change a hair of that.

            No evasion at all I told you straight up it was a source that I didn’t have verification of. It may well be in the documentation of Had-crut 3 or it was in the ruminifications by James Hansen, who happens to be a scientist I do like because he is straight up and open about what he is sure of and what he isn’t.

            Actually a humble man even though he strongly believes in the Arrhenius theory.

            So fine you don’t know. And I don’t feel any need to educate you further.

            Fact is the only thing that matters about that inaccuracy is UHI and other anthropogenic changes and not how much there is of it in the record, which is quite considerable, but what matters is how much its changing. Obviously mountain terrain isn’t changing much and oceans despite predictions aren’t washing over New York highways.

          • bill hunter says:

            Nate so much with your obfuscating. UHI has been discussed at length for decades with no resolution. It is one of the most important reasons to move to satellites as the surface weather stations were never sited or designed for the purpose of measuring mean global climate.

            Of course you probably have had your head buried so deep on that for so long I suppose you are completely unaware of it right?

            Yes it has been discussed here as nauseum. But in the scientific literature, studies of it (see Berkeley Earth) show that that the current data sets change negligibly as a result of it.

            Your dreams for it to add uncertainty are just that, dreams.

            Yeah if you want to call that study good, that’s your personal choice. I thought the sampling examples left a lot to be desired. I truly am not worried about UHI but I am interested in the science.

            I once lived in a house with a big open patio on the west side. Had no air conditioning and only kitchen windows on that side of the house to let the westerly afternoon breezes blow through the house. That patio made it almost unbearable in the summer. So I took some of the concrete out, planted trees and some greenery and it improved the situation. This was back in the late 70’s so it wasn’t a climate experiment.

            Check out Figure 8 how they spliced this to the temperature record. The bulk of the proxies end about a thousand years ago. The one proxy comprising 43 records extends to about 250 years ago and shows the LIA to be hotter than the MWP. Then Michael Mann takes over from there and we all already know about that.

            Can we please stick to one point at a time, and narrow it down until we’re done with each point?

            If you read the fig. 8 text it says:
            “No instrumental data are shown.”

            It’s from PAGES2k: https://tinyurl.com/y442z4qe

            PAGES2k has “692 records from 648 locations” and “Nearly half of the proxy time series are significantly correlated with HadCRUT4.2 surface temperature over the period 1850-2014”.

            Michael Mann is not among the fifty or so authors in the two papers.

            ================================
            Points? You started out with conclusions Svante.

            ====================
            =====================
            ======================

            Svante says:
            Michael Mann is not among the fifty or so authors in the two papers.
            ===========================

            Svante he is the main author, yes he is being treated here as a ‘shadow’ author, but all you need to do is dig down into the underlying proxies and there you will find him all over the place.

            You can just read the first page you always need to verify the authenticity of the underlying assumptions which in this case are temperature records constructed on proxies patched together in a network. You have several climategate shadowy figures deeply involved in the temperature interpretations of these papers.

            I am not saying the papers are wrong Svante, what I saying you have people with very little credibility involved here, climategate conspirators, who openly discussed how to most deceptively present the data to be convincing to policy makers.

            There is no question of the bias that is also undoubtedly embedded in the results if they do not in fact drive the results.

            Look I am no virgin at this. I have been involved in multiple projects to optimize a desired solution in very similar GIS analytical work. It is incredibly easy to do, all you need to know is what your objective is.

            I have done several projects where data was presented as optimum and myself personally using the datasets and the proper GIS software come up with far more optimum solutions, once you remove the bias and truly aim for say least economic impact outcome on the data presented. Usually the bias is for a hidden economic benefit for a particular party, sector, or political objective.

            So now that you have been taught to look at any proxy with a critical eye and withhold your conclusions such as about being the best because its the most what did we learn from pages 12k? That warming is quite modest in terms of natural variation. You can run a statistical analysis on the variation seen in the output of this report along with the quantitative uncertainties and find really no significant trend in warming over the past 12 thousand years. I don’t need to actually do that, I can see that without doing that its so obvious.

            You would like to point out the steepness of the current trend but thats extremely sophmoric. Fact is proxies lack details of short term runups, they miss peaks, and steepness of short term weather phenomena, and even of moderate climate change periods like decades and often centuries as well.

            Svante says:
            If you read the fig. 8 text it says:
            No instrumental data are shown.

            ================================
            You are right Svante, instead what is shown are Michael Mann reconstructions of instrument data. Observe and read the legend of Figure 3.

            And you will find it> https://www.nature.com/articles/s41597-020-0530-7#Fig3

            The whole paper really is a Michael Crichton-like State of Fear reconstruction. The details of what is being shown is buried under the footnotes. No deception Svante perfect semantics to say an instruement record hasn’t been shown when an intervening paper included it in a multi-proxy. Its just hide the decline on a monumental scale. Check the inset for figure 3 where the red, blue, yellow, and orange proxy reconstructions run out and and what is left is the black instrument line.

            Thats all fine I don’t object when its all forthwith or its a reanalysis of instrument data or its instrument data. Bottom line is overall in the last 12,000 years there is no significant trend in temperature.

          • bill hunter says:

            Another point should be perhaps we should limit warming from the top of the 12k analysis to uh a maximum of 2 degrees and start taking aggressive action when its 1.5 degrees. Or if you want to be super aggressive say a 20 year average of 1/2 a degree more than now.

            The reason I say thats super aggressive is the error bars in this would be hugely much larger than the shaded area. Even the error bars for current global mean surface temperature is believed to be within + or – 2c. And its super aggressive because current warming while rapid it doesn’t match well to increases in CO2 and the IPCC has found that 30% of the warming is identifiably natural.

            So anyway you want to cut it, aggressive or conservative, its still only at best about 8/10ths of degree industrial era warming and quite apt to get smaller in the next decade as that natural warming component doesn’t include the most recent El Nino cycle.

            Svante you have to know what an auditor does before you call him weird. Being called weird is a phrase similar to what an auditor hears every time when he finds a mistake or a lack of due diligence or a lack of controls, or even fraud is denied.

            Replication of a proxy or a temperature record isn’t like a replication of an experiment. Especially when you simply order the computer to recalculate. Or add an additional proxy or search for more stuff that fits the mold.

            Building evidence of a case is a process of finding everything that supports your case and handwaving away evidence that suggests otherwise.

            Get good at that and you can have a bright future of exotic travel, a-list tea parties, celebrity elbow rubbing, fame in journals and media, promotions, appointments, control of immense finances.

            ============================
            Thats not a number I came up with Nate.

            Thats a number acknowledged in conversations with those maintaining the temperature records, there is a general acknowledgement in the trade that quite a few earthly environments are very badly represented in the temperature record and a large amount of inconsistency of how temperature is measured. For example, few weather stations exist in forests, mountain tops, rugged terrain, lakes, glacier, ice sheets. Airport and city type terrain is far far over represented. Plus large differences in methods between ocean and land.

            One simply cannot make an argument that says the surface records are a true representation of climate temperatures. But the argument use instead is that anomalies are not significantly affected by this heterogeneity. There are big temperature differences between urban and rural and big temperature differences depending upon vegatation types and heights.

            In my first meteorology class the class took a highly accurate thermometer across campus and took ground level temperatures then the elevator to the roof of the highest building on campus, which was about 12 stories if I recall correctly and we could see almost a 1/2 degree centigrade difference between ground level and the top of the building.

            Most cities and towns are built on the plains around which mountains can make up a large part of the terrain. Seems to me a 2,000 foot mountain makes for a 4C difference per US standard atmosphere. We have a few mile high cities but those even tend to be dwarfed by mountain ranges surrounding them.

            Satellites may have the same problem if they don’t have algorithms to deal with elevation of the land the scans are passing over. I don’t know enough about the technology to opine on that topic.

            Too bad you are too ignorant of climate science to even had a clue about that to just spout off about it as if it was a bad representation of the facts without a shred of evidence or even a logical argument of what the error is.

            And to further demonstrate your stupidity and cluelessness. . . .auditors never represent anything. The job of the auditor is to simply test the representations of the auditee and obtain the evidence supporting the auditees assertions and then indicate if they have qualifications about it or not.

            When an auditee is not forthcoming with evidence the auditor just assumes he is talking to the wrong underling in the organization, moves up the ladder talks with supervisors and finds out who should know.

            Since different people have different jobs in an organization the process moves on getting what is known by those who know. Its amazing how many people an auditor runs into who thinks they know what is going on in an organization and actually doesn’t have clue one.

            You are like that Nate as you never can back up your assertions. You operate entirely within and envelope of an unknowledgeable narrative. You spout textbook physics like that was the only thing you have actually seen in life.

            When asked for definitive evidence of your definitive beliefs you always come up short. Do you actually do anything with that degree of yours or are you just fresh graduate stupid where you remember the cartoon representations of overly simplified descriptions of the world but totally lack any real world experience using those tools? Please elucidate on that.

            ====================================

            Well from that one can conclude that nobody has pushed the boundaries on this ever in terms of proof of a GHG mechanism that actually results in a greenhouse effect defining both the necessary and sufficient components of such.

            At least celebrated atmospheric emissions expert Dr. William Happer discovered the sodium guide star. He pushed the boundaries. I asked you for evidence of anybody pushing the boundaries currently involved in climate science and all you have so far is a lot of untested theories about as well defined as the Big Bang theory.

            Then we have you adding 1366 watts from the sun to 400 watts from GHG in the atmosphere and claiming that results in the same thing as a 1766 watt light!!

            Thats fantasy land stuff that simply does not follow from any physics I am aware of. Or any physics you have been able demonstrate it exists. I think you are gradually descending into insanity. The theory you are believing in was proven wrong by Dr RW Woods over a hundred years ago.

            I even offered you an opportunity to prove to yourself how wrong headed that is. For as little as $100 and a small investment of time you can save yourself from a lifetime of ridicule. What a Deal!!!

          • Nate says:

            Actually Hansen pushed the boundaries by making a bold quantitative prediction with a simpler model in 1981. You don’t like the results.

            And as a matter of fact, Michael Mann pushed the boundaries by pioneering the millenial global temperature reconstructions, and discovered the evil vile Hockey Stick.

            And after much yelling and screaming and many different groups with different methods working on it, its still holding up.

            Actually not 1366 W, a lot is reflected and some is abs*orbed before reaching the ground, but yes 400 W from the GHG could be added to the remainder.

            You are still trying to deny this basic physics point?

            You are better consulting with your team of experts on this one then to follow the lead of the troll Clint.

            Great example of what is wrong across the board Nate!!

            Embracing facts, embracing uncertainty, being straight with people is how you build buy in.

            You have to be a bigot about the intelligence of the people to treat them like mushrooms in a mushroom farm, keeping them in the dark, feeding them shiit. You see it all over the place, absence of error bars, absence of descriptions of uncertainty, lack of analysis why such uncertainty can be essentially ignored. Treat people like they are intelligent is the only way to get them to act intelligently.

            Those unaware of that are either ignorant or have a hidden agenda.

            So in short you can shove all that stuff about me not providing links to where the sun doesn’t shine. . . .not my job. . . .never an auditors job.

            AFAIK that is not even close to being correct.

            And still nothing. No data. No source for that factoid.

            Then, well, obviously you just made it up. Thats what you do.

          • bill hunter says:

            No evasion at all I told you straight up it was a source that I didn’t have verification of. It may well be in the documentation of Had-crut 3 or it was in the ruminifications by James Hansen, who happens to be a scientist I do like because he is straight up and open about what he is sure of and what he isn’t.

            Actually a humble man even though he strongly believes in the Arrhenius theory.

            So fine you don’t know. And I don’t feel any need to educate you further.

            Fact is the only thing that matters about that inaccuracy is UHI and other anthropogenic changes and not how much there is of it in the record, which is quite considerable, but what matters is how much its changing. Obviously mountain terrain isn’t changing much and oceans despite predictions aren’t washing over New York highways.

            “So fine you don’t know. And I don’t feel any need to educate you further.”

            LMAO!

          • bill hunter says:

            I suspect what you are looking at is probably various runs of computer gridding programs and the kind of variances found by employing different gridding parameters. Which of course would not touch on the representation issue.

            How would I know that? Well there are a few principles you learn with experience. One is that to do it right would cost a lot of money and if you spent the money you would want to publish the result. Changing parameters on a gridding program multiple times and running them probably takes less than a day for one guy to do. Why? Because I do that kind of work all the time.

          • bill hunter says:

            Nate do you always fire from the hip? I wasn’t talking about the accuracy of the anomaly database. I was talking about the absolute temperatures. Thats like 288k rather than .8k.

          • Nate says:

            288 vs 0.8 ?

            Red herring.

            In the instrument era, the absolute temperatures are measured. Then a constant offset is applied. The error is ~ the same for abs temp and anomaly.

            The error is still << 2 degC.

            There are slight diff between data sets because some sets incorporate higher latitudes.

            In the paleo or reconstruction records the error is of course larger.

          • bill hunter says:

            You are the only one dispensing red herrings Nate.

            The big dog in surface database errors is UHI. It’s a very large number and its only questionable how much of that number leaks into surface record trends. Putting on horse blinders doesn’t make it go away.

            But in fact:
            ”once again above the 1998 peak”
            ”second warmest September on record.”
            is just as much a conclusions as:
            ”a rate of warming of .25degC per century”

            The latter though is more informative as its not just simply comparatively ranked but gives a quantified rate of what occurred over 22 years.

    Is there such thing as a “correct” global mean temperature? And if there is, what is it and why?

    Our previous Interglacial Period was warmer than this one. An argument can just as easily be made that our global mean temperature is too cold.

    • Rawandi says:

      On the climate issue, it is crucial to have a historical perspective. The global cooling of the 17th century killed around a third of the world’s population. Therefore, the current global warming is a blessing for humanity.

    • Galaxie500 says:

      During the previous interglacial period there wasn’t 7.5 billion people on the planet which kind of makes a big difference.

      Of course there is no correct global mean temperature I believe this is a misunderstanding of the issue. We need to avoid rapid warming as this will impact coastal populations through sea level rise, impact where crops currently grow best and lead to population migration as hot regions get hotter.

      • Swenson says:

        G,

        And, of course, you are terrified that vast areas will become productive once again, if they become a little warmer.

        Good luck with your efforts to prevent the climate changing. As to sea levels, you do realise that some 6000 m mountain peaks used to be below sea level, dont you?

    • bdgwx says:

      What does “correct” mean to you? What is it you are wanting to optimize?

    • Robert Ingersol says:

      Likewise, is there a “correct” sea level? Geologically speaking, the answer is clearly no. Where it has been for the last 2000 years is in no way better than a meter or two higher. Of course geology doesn’t have to pay taxes to rebuild coastal infrastructure.

      Now is there a correct percentage of California that should be covered with trees?

      • Joel Dickson says:

        I’m trying to understand your points. Geologically speaking, why did you reference the 1998 peak? Why is 1998 more significant than the all time peak over the geological past or more significant than various peak temperatures that can be determined by taking say, 100 or 500 year slices of time from the geological record?

        In the time period inferred by your reference to 1998 can you break down for me the amount of warming due to natural warming and cooling influences that have been present since time immemorial versus the amount of warming due to C02 added to the environment by human activity? And then for the peak temperature for each 100 or 500 year slice of time in the geological past can you help me understand how much of that peak can be attributed to natural warming influences versus C02 added by humans?

        Since you made the economic argument that geology doesn’t have to pay taxes to rebuild costal infrastructure, can you tell me the net present value cost difference to society between the scenario where we incur costs to eliminate human contributed C02 from the environment as opposed to the scenario that calculates the cost of rebuilding costal infrastructure caused by sea level rise due to C02 added to the environment by humans?

        • Robert Ingersol says:

          So all you are asking from me is a full accounting of every climate event since “time immemorial”? How about you just read the scientific literature?

          What is significant about 1998? Well, for one thing, it was the onset of “the pause” that was supposed to signify the end of the “AGW hoax.” How is that working for you? Just like “no decline in sea ice since 2012.” How much longer is that going to pass the giggle test?

          As for the cost of replacing FF with renewable energy, I am a chemist, not an economist. But I note that FF is a finite resource (and extraction is getting increasingly expensive now because we have already taken the cheap/easy stuff). We will need a replacement soon anyway. Wind, solar and batteries are already cost competitive in many cases and getting cheaper. Add in the other environmental benefits and there are clear advantages to doing this now.

          • Joel Dickson says:

            First if all you didn’t answer any of the questions I asked of you. You simply deflected and pivoted. Your deflection and pivoting demonstrates you don’t know the answers. You asked me to read the scientific literature. I have read dozens of peer reviewed studies as well as the various IPCC assessments and from reading them it is clear that the scientific literature attributes all warming since 1998 and indeed back several decades before then to C02 from burning fossil fuel while attributing no warming to natural causes. If you would have read the scientific literature you admonished me to read, you would have known this. Or perhaps you did read it and didn’t understand it.

            I am an econometrician and am very familiar with complex mathematical modeling and stochastic analytical methods that are used in various modeling environments including both economic modeling and climate modeling. You can divide the geologic time line into discrete timelines of 100, or 500 or even 1,000 years, each of which would have a peak temperature associated with it. The problem is that any discrete historical time period selected in which we know natural influences were the primary drivers of the peak temperature, needs to be differentiated from time periods which have human caused C02 as the primary driver of the peak temperature. Once this is done the amount of warming that can be attributed to natural causes can be known. When it comes to time periods where significant amounts C02 were added to the environment by human activities you only have a narrow window which represents a single data point that you have available to use in your differentiation analysis. With a single data point your confidence interval is infinite and your analysis is meaningless.

            I note that you claim you are a chemist and not an economist. Your comments on the economics of abating the man made effects of global warming certainly demonstrate that your statement of not being an economist is true.

          • Rob Mitchell says:

            Are you giggling about the Antarctic sea ice extent running in the top 10% in 2020 since the satellite era began?

          • Midas says:

            Here we have someone who has looked at the graph of Antarctic sea ice extent, and believes that if this year’s extent lies inside the interdecile range that it is in the top 10%. This is what happens when mathematically challenged people involve themselves in science.

            bill,
            Your comment is in the wrong place, but I assume you are talking about LIA recovery. It means a temperature increase without a cause. First a perturbation away from equilibrium, then a return. The further from equilibrium, the stronger the correction, less strength the closer you get to the old value.
            So we would expect a flattening of the curve as we approach the old value. Instead we got an acceleration as we exceeded the old level.

            a record breaking solar grand maximum is a direct cause, so that is different.
            =====================================

            I would think the earth could walk and chew gum at the same time even if you think thats a bit challenging.

            Obviously climate is subject to a variety of internal and external perturbations and even 800 year delayed reactions to such perturbations if they are sensibly significant enough to have significant influence on the deep ocean.

            Probably the best evidence of that is the 800 years it takes for CO2 to peak in the atmosphere after warming has ceased. Since the industrial age is at best 170 years long and 90%+ has been in the last 50 years. So the perturbation of anthropogenic emissions has to be a drop in the barrel compared to the iceage glacial change data.

            Milankovich theory could be a major contributor to mean global temperature oscillations of 3c to 10c (we really don’t even know which is closer to correct and its apt to stay that way until we go through the cycle) as areas of the world go through greater climate change than that seasonally every year.

            CO2 used to come from Ocean outgassing, as a slow temperature feedback. Now CO2 is way ahead, and the Oceans are a net sink.

            So the perturbation of anthropogenic emissions has to be a drop in the barrel compared to the iceage glacial change data.

            Well if change is scary for you without evidence, at least you might look more closely as to any significant change has occurred.

            Measuring CO2 in the air when ice isn’t accumulating is a bit different than looking at it in ice long after it accumulated.

            thats is an important step in validating a proxy, especially when the IPCC has found that CO2 could drop by 50% of the perturbation in 2 to 3 decades.

          • Svante says:

            There are many other proxies for CO2:
            https://mashable.com/article/climate-change-carbon-pollution-15-million-years

            There may have been a time, roughly 3 million years ago during an extremely warm period called the Pliocene Epoch — when sea levels were between 16 and 131 feet higher than today — during which carbon concentrations could have approximated present levels.

            “However, the concentration of CO2 currently in Earth’s atmosphere is higher or is nearly as high as it has been over any time period during the past 15 million years,” Daniel Breecker, a paleoclimatologist at the University of Texas at Austin Jackson School of Geosciences, said over email.

            The critical difference today, however, is that carbon emissions are expected to continue rising. With the unprecedented burning of fossil fuels, carbon accumulations will simply keep going up.

          • bill hunter says:

            And oddly enough continued accelerated carbon emissions are probably the most direct path to few carbon emissions. Just that some on this roller coaster ride really don’t want to be on it.

            Svante says:

            What does that mean?

            =================================

            Well I understand well how little you understand this most basic fact. Fact is science continually advances at an accelerated pace in proportion to how much time and labor can be diverted to such endeavors.

            Fossil fuels are unquestionably the largest factor in getting that done. They are inexpensive because they involve less labor to extract than alternative fuels.

            Pre-scientific era was largely due to everybody needing to devote time and effort to more important stuff like surviving.

            Now we have a controlling elite class who don’t care that some people are still struggling. They are more interested in their heirs.

            That goes double and maybe triple for the third world. And gee we recognize that if you are living a 3rd world existence you need assistance, and the proposed way of doing it is by ignoring the fact that many our own citizens are living 3rd world lives.

            So this goes around. We want to change the morality of the world to the elitist hedonistic realities of modern life in the developed world. We aren’t convincing hardly anybody so we have to dream up better schemes about future disaster and free handouts to get that buy in. Of course very few liberals actually are helping now, no they want somebody else to contribute. They want that guy with a new job to pay just as he is starting a family.

            He is the guy that commutes the furthest, uses fossil fuels the most to get to work and raise a family. There is no question that fossil fuels have been and will be for the foreseeable future the best path forward.

            Its only special and self interest that might see otherwise. And of course evil men seldom think of themselves as selfish, self centered, narcissistic, or dishonest.

            But this is a great forum attracting those sorts displaying blatantly their deceptiveness. Congratulations on being part of the cure.

          • bill hunter says:

            Svamte, just curious what your take is on these quotes from your reference?

            “For the most part, carbon dioxide was below 400 ppm for the last 14 million years or so,”

            ”Of course, C02 concentrations aren’t stopping today,” said Lachniet. ”We’re probably going to blow through 550 to 600 ppm.”

            Those sorts of high carbon concentrations haven’t been experienced on Earth in well over 20 million years, noted Lachniet.

            I would probably point out that the last comment isn’t in quotes, when the rest were. What’s missing? Why was this journalist moved to not provide the exact quote?

            Could it be a qualifier that the current level of sampling isn’t of high enough resolution to detect even multi-centennial variations? That would be my guess as a great deal of such work does lack sufficient resolution to pin it down to where no transients have occurred in the past.

            Fine I really don’t have a problem with there is a recent world history analogue or not. I do have a concept of limits that we haven’t yet approached. 600ppm could be 70 to never in the future depending upon technological advances that find ways to provide competitive alternatives. I even posted an article in this thread that suggest we have to do nothing from a government perspective because renewables are already competitive enough to grow robustly over the next couple of decades.

            You never even responded to that.

    • Gordon Robertson says:

      binny…”This way you better understand why I laugh when I hear Its cooling A LOT.”

      You regard 4 years of warming, following an 18 year flat trend, where 2 months have peaked, as an indication of something. You ignore the 18 years of a flat trend from 1998 – 2015, 15 years of those confirmed by the IPCC.

      You fail to get it that parts of the world must be cooling in order to offset the parts that are warming. Since parts of the Arctic are +5C above the norm other parts must be nearly 5C below the norm to allow a global warming of under 1C.

      Of course, your authority figure is NOAA, who retroactively went back and fudged the SST to show a warming rather than a flat trend. The same NOAA who has slashed 90% of its reporting atations since 1990, and who think nothing of using climate models to fill in the slashed stations using interpolation and homogenization statistical techniques.

      • AverageJon says:

        The “18 year flat trend” only exists if you cherry pick the dates. Yes, there was a very strong el Nino in 1997/1998 and it messes up trend lines that start around 1997/1998.
        How can you honestly look at the data and not say that there was a warming trend from 2008 through 2016 or from 2012 through 2016?
        Why are you ignoring the warming trend before 1997?

        • Midas says:

          I am a strong supporter of climate science and not a denier.

          But I have to agree that there was a pause in the warming.

          The UAH averages for 2005-2010 and for 2010-2015 were both slightly lower than the average for 2000-2005. And that misses the 97/98 El Nino.

          That has been more than made up for in the last five years though, with the 2015-2020 average rising above the 2010-2015 average by as much as the TOTAL rise from 1979-1985 to 2010-2015. In other words, we are higher now than if we had extrapolated the 1979-2005 trend without the pause.

            In finding slightly lower averages for 2005-2010 and 2010-2015 than for that of 2000-2005, isn’t that simply a function of using such short time periods, five years, as your units of analysis? Surface temperatures and atmospheric temperatures are subject to many sources of natural variability, and over short periods of time that natural variability can overwhelm the effects of anthropogenic climate change. But when you lengthen the time frame to a decade, the effects of natural variability get washed out and the pause disappears, as illustrated in the following graph:

        Just a glimpse at any of the global temp records (even the suspicious outlier, UAH) shows that there never was a pause. If you were confused, try looking at it starting in 1999. 1998 is a cherry pick.

        Further confirmation of that comes from your fellow climate science deniers who have stopped talking about “the pause” because it is an embarrassment. 1998 was a jaw dropping heat spike at the time. It is not even in the top 10 warmest years now (surface records). Last 7 years (including 2020) are all warmer than any previous year in the 140 year record. Climate science deniers predicted cooling and they were wildly wrong. Climate scientists quantitatively predicted unprecedented warming with uncanny accuracy. Why are we still debating this?

          Just a glimpse at any of the global temp records (even the suspicious outlier, UAH) shows that there never was a pause.
          ================================

          UAH did show a pause. So did Had_crut 3 before it was determined they need to go global and eliminate the 1930/40’s blip. That is what one could identify as suspicious if one was inclined to go down that avenue. Which I am not.

          If you were confused, try looking at it starting in 1999. 1998 is a cherry pick.
          ==========================
          Nope, if you are going to create a trend line across maximum peaks as is necessary to bring it to the present. One needs to lay the linear line down on the peaks like a long beam sitting on the longest posts to find a natural trend line. If you create a trend line that has one end of the line sitting on the ground and the other on a post you have created a false trend.

          But I guess you aren’t bright enough to figure that out on your own.

          Robert Ingersol says:

          Further confirmation of that comes from your fellow climate science deniers who have stopped talking about the pause because it is an embarrassment. 1998 was a jaw dropping heat spike at the time. It is not even in the top 10 warmest years now (surface records). Last 7 years (including 2020) are all warmer than any previous year in the 140 year record. Climate science deniers predicted cooling and they were wildly wrong.
          ===========================

          Seems to me you are cherry picking skeptics. I never said cooling was imminent. One has to realize that climate itself has a lot of variation. Attempts have unsuccessfully been made to either classify such variation as short term weather and where that hasn’t been possible through a rewriting of history. And still all those attempts remain incomplete. Its not easy to do. Some really out there radicals will try to take it to the extreme and start book burning. Sort of basic human nature on the part of those types of wannabee authoritarians.

          =============================

          Hmmm, where did you read that? For years about all I have heard in that regard were frantic searches for the missing heat. If the heat was missing thats not an accurate prediction FYI, even if you claim to have found it. What that is either an excuse or a learning experience. If its an excuse its not likely you will do better in the next round. If its a learning experience then you may do better in the next round.

  8. Scott R says:

    It looks like the tropics have dropped back a tad, but they are still very elevated, not reflecting la nina conditions. If you look at 2017 as proxy, the enso region started cooling mid-year after a brief warm spell, but around September, UAH ocean tropics were still at +0.53. By early 2018 they had dropped below baseline which is what we should expect out of this la nina.

    Bindidon to continue out discussion about the EGP station, I have downloaded the data, and replaced the missing daily readings indicated by -999 by interpolation. There really were not that many missing days. 10 over 5 years. I then overlaid this years data on top of other years so you can see how much we are hugging the bottom of the normal range. Due to the short data set, I did a count of the number of daily records hot and cold. The cold outnumbered the hot 75:44 and 18 of the last 18 records were all to the downside.

    So how does this fit into my multiple timeframes theory? It all comes down to the relationship between the AMO and the Beaufort Gyre. There are 2 multi-decadal climate forcers… the 42 year and the 60 year. How these forcers combine and cancel is responsible for the majority of our decadal climate changes. During the last AMO peak, they were not aligned. That is why this AMO peak is higher. The 42 year cycle is driven by a multi-decadal cycle in the tropics linked to the solar cycle. The 60 year cycle has to do with the barycenter movement of the solar system, where sunspots are located on the sun. All you need to know is the Beaufort Gyre is filled with fresh, cold water right now because it has been bottled up by the combined 42 / 60 cycles for the past 20 years. Now both cycles will drop together and this water will be released. We should go deeper than the mid century cooling because at that time, the cycles were still not aligned to the down side. You had the 60 year going down, but the 42 was holding it up.

    From the perspective of the USA….

    Global CO2 emissions increases ~10,000 Million metric tons every 20 years. USA’s portion was ~30% in the 70s and now ~12%, likely ~8% in 20 years.

    For the sake of argument, if trillions we don’t have were spent to eliminate our emissions in 20 years, global CO2 emissions would still increase ~15% instead of ~30%.

    Is there anyone who has a concrete, executable plan to address emissions from China, India, etc first, since the USA has already been reducing it’s CO2 emissions slowly over the last 20 years?

        I’m pretty sure the equations include CO2 molecules, not CO2 molecules per capita.

        Barry

        • Tim Folkerts says:

          Barry,

          These are not easy issues. There is no easy answers. But it is impossible to decrease CO2 while simultaneously:
          * maintaining current population levels.
          * consuming energy at the rates in the US.
          * relying on current energy sources.

          Some very hard decisions will need to be made if the goal is indeed to decrease global CO2 output.

          We could try:
          * dramatically decreasing the overall population (but population control is VERY tricky — ask China).
          * becoming more energy efficient per capita, like driving less, LED lightbulbs, smaller homes, (But if you live in India and are hardly using any energy, there is not much to cut).
          * finding new or bigger ways to tap into energy sources. (Expensive and these have their own environmental impacts).

            Where I am, forecast is 39 C. Not too bad, it gets hotter at times. Too much CO2 about, do you think? Cant see why. Not much population, not many cars, no heavy industry, not much of anything really.

            That CO2 must work better when the temperature is high, do you think?

          • Tim Folkerts says:

            Clint, and only idiots would wishfully ignore a serious problem.

            Hopefully the wise people are in the middle. Realizing that global warming is definitely not imaginary, but also realizing that it is not responsible for every weather event. Realizing that some steps can be taken easily and effectively, but that we shouldn’t shut down the world to deal with CO2.

            Neither the extreme you postulate nor the extreme you project onto me is a good starting point.

          • ClintR says:

            Tim, you are ignoring the problem. The problem is that too many people want to ignore reality. That is a serious problem. It leads to bad things, like lawlessness and rioting.

          • barry k says:

            If global CO2 levels are a problem, there is no viable solution currently and that is my point. A solution that does not include China, India, etc, is not a solution.

            Population control is a lot more than ‘tricky’…

            If you want to try your other suggestions yourself or in your community, go for it. But, nationally we are already reducing our contributions steadily while the rest of the world is increasing rapidly.

          Tim,

          I don’t think the USA has a moral right to demand China and others not do what we’ve done. I’m just asking what mechanism even exists.

          Also, since the USA’s contribution is small and shrinking, we’re already doing our part at the moment.

          Barry

          • Midas says:

            How does 15% of global emissions for 4% of the global population qualify as “small”?

            Per capita, the only western countries with more emissions are Canada and Australia.
            It is about 25% more than Russia, 50% more than Japan, double China, more than double the entire European’s average, and almost triple the UK.

          • Midas says:

            “European’s” should be “European Union’s”

          • barry k says:

            Midas,

            Per capita is a moral discussion. ‘The models’ use CO2 molecules.

            Energy policy takes decades. USA is decreasing ~1% per yr (same as EU) and China, India, etc are increasing single digits % per yr. USAs contribution will be <10% in ~20yrs. Spending trillions to reduce USAs part more will be useless until the bulk of contributions is reducing.

            Barry

          • Midas says:

            If you are going with total emissions, then the US is second highest after China.
            So in your words, the US releases the second highest number of CO2 molecules.
            You really should have stuck with per capita. But if you want to make your argument worse, who am I to argue.

            Anyway, same question … how does that qualify as “small”.

          • barry k says:

            Midas,

            So I think 15% is small and you think it isn’t.

            That doesn’t address the fact that USA is decreasing along with EU and China etal are increasing and it appears they will be for a while.

            Barry

          • Midas says:

            Not 15%. That is meaningless.

        =======================================

        Well is 1/2 as much the target? Or is it 1/8th as much? Then we can determine who should get paid to change if anybody. That’s the standard that Turkey is holding out for. Seems to be the right approach.

        From a practical point of view the nations that have signed on to the Paris agreement account for 85% of the emissions. Thats a sufficient experimental sample don’t you think? For if you don’t get a result on that you aren’t going to get one with 15% more.

        We can follow their lead as they prove the pudding. Only neocons, hegemonists, and ‘closet believers’ in American exceptionalism believe the US should take the lead on this.

        there is another issue as well. The US is one of the few nations in the world that conforms to voluntary agreements (when properly ratified). Only the threat of enforcement induces most. Where no threat exists like in the Paris Agreement the only route to compliance is by actual willful belief in action being effective in improving the cost/benefit balance sheet. So more so perhaps than any modern agreement the Paris agreement is a broad test of that concept. I have little doubt American’s will jump in with both feet once the goodness of the pudding is observed.

            So the objective of the trade war is some form of reasonable parity and its definitely achievable.

            I was being satirical about a tariff on goods produced by fossil fuels. That might be something some ignorant nation might pursue that could have some positive outcomes for them if they still have a consumer class when its all said and done based upon the harm they do to their own economy by eschewing fossil fuels because its not too likely they will be competitive on the world market for real goods versus intellectual goods.

            Indeed that should be the case should it be shown that fossil fuel burning is bad. But so far its been good.

It provides the production capabilities of building homes and structures for protection from the elements for billions. It provides for modern agriculture that creates vast amounts of free time for people to invent other stuff to improve our lives. And we should charge people for it? That would be like taxing air.

          Optimum for what?
          ========================

          CO2 supplemented agriculture Midas.

          The planet optimum may be higher as the agricultural optimum is restrained by the cost of supplying the CO2 which is essentially by burning propane or natural gas which has a hefty price tag.

          In a natural system where the gas is being readily supplied elsewhere at essentially zero marginal cost the optimum would certainly go to a higher level unless other costs are actually observed and attributed properly.

          Optimum is rather pretty clearly associated with the idea of maximum sustainable yield for feeding the World’s population. History has shown that having sufficient food is one of the greatest risks to survival.

          To understand what that is one has to allow for enough freedom to actually learn what the limits are. It seems rather apparent we aren’t encroaching on that boundary now despite all the false fear mongering about CO2 lingering in the atmosphere. That has already been debunked by the IPCC.

          The idea of restricting learning is what makes the ”precautionary principle” so dangerous to our well being. It really is more like a religious belief held by those who know little about living an independent life. It’s one thing to watch Bear Grylls episodes and quite another actually living them.

        Its not the same kind of problem. Flourocarbons may have been beneficial for refrigeration and harmful the atmosphere.

        CO2 is beneficial for a far wider range of things than refrigeration and is equal important as a life giving gas in the atmosphere. One should be very sure that it poses a very serious problem before taking action.

        Other nations have agreed to take action. If they don’t that would be typical. As it stands when the US enters an agreement to take action we do. Then it requires strong punishment for violators to get the rest to come along.

          It’s ironic that since they banned fluorocarbons that another ozone hole opened over the opposite Pole. It’s the same with the banning of DDT based on Rachel Carson’s propaganda re its effect on the eggshells of raptors (bird of prey). So, the only chemical we have against mosquitoes, the cause of malaria, that kills millions each year, was banned because it was theorized that DDT was causing the shells of raptor eggs to thin.

          Lo and behold, many years after banning DDT, it was discovered that raptor eggshells had been thinning long before DDT and well after it was banned. This is why I am so opposed to climate alarmists. I don’t want them imposing pseudo-science on the rest of us based on their religion of false beliefs.

            Gordon do you have a reference on that shell thinning discovery? Here in California the focus was never on the thinning of egg shells of raptors but instead was on the thinning of egg shells of Pelicans.

            The Pelicans made an amazing recovery sometime after DDT was banned. But major ocean changes were underway at the same time with a resurgence in sardine populations. Anchovies a much smaller forage fish was abundant during the decline of the Pelican that was blamed on DDT. Just read an article in the rag Scientific American blaming residual DDT for continuing problems with the California Condor.

            But wait!! The Pelican is a big clumsy bird that dives into the sea with a big pouch mouth open to nab prey. It is also possible because of the lack of sardines and nutrition that the pelican went into decline. And that also makes a lot more sense for a giant scavenger bird not having the kind of carrion it had back in its heydays.

            Lots of big animals perished during the Holocene in California. The La Brea tarpits is a huge repository of giant sloths, huge short face bears (largest known bear), clumsy powerful sabre tooth tigers, huge lions, mammoths and more. All believed to have perished due to a lack of nutrition in the Holocene. I would be interested in reading it if you have a link.

      The Arctic is certainly the fastest warming region over the long term, but by area it is not the largest region, so saying it is the “driver” might be pushing it. In UAH the Arctic, ‘NoPol’, covers 60-90N. Land areas of the northern and southern hemispheres and the tropics are also warming faster than the global average.

    • Gordon Robertson says:

      bill…”The Artic region seems to be driving these higher average global temps. Any idea why?”

      I don’t think the Arctic has anything to do with recent global averages. This is a hangover from the 2016 El Nino, which has been prevented from cooling off for some reason. I have cynically offered one opinion for that condition, that NOAA, who provides the sat data, is messing with the data before UAH receives it. The have fudged the surface temperatures badly, why not their own sat data?

      The Arctic’s temperatures seasonally vary from around 0C down to -50C or so.

      Have a look at these global temperature contour maps from UAH. Note that warming in the Arctic for September 2020 is represented by a tiny region that appears to be north of Russia with a warming of +3.5C. Opposite that, over Greenland, there is a cooling of -3.5C which cancels out the warming leaving the Arctic with little or no warming during September 2020.

      If you go back to January 2020, in the Arctic winter, you see basically the same thing but with the warming patches having moved.

  11. Peter Hartley says:

    For all the commenters above who are pointing to “breaking records”, “positive trend” etc hinting perhaps that this is evidence of increasing CO2 causing increased temperatures, if one looks at the actual monthly temperatures from the UAH web site one finds, in fact, that over the whole period the hypothesis that the temperatures are stationary cannot be rejected. Like many other climate variables they appear to be fractionally integrated. For example, the Globa Land monthly values are fractionally integrated with a coefficient of around 0.45 and the Global Ocean with a coefficient of around 0.43. However, the estimated standard errors would mean one could not reject the hypothesis these coefficients are equal. The key point, however, is that these are stationary time series while the CO2 content in the atmosphere is non-stationary. That does not look good for the hypothesis that CO2 content drives temperatures.

    • Peter Hartley says:

      I was called away before I could finish the previous comment. I meant to say that having TLT monthly temps stationary with CO2 content in the atmosphere non-stationary is not good for the linear model linking CO2 content to TLT.

      Looking at the data further, it is interesting that the degrees of long-term persistence in the UAH TLT data differ geographically:

      Region Fractional integration
      South Pole Land 0
      South Pole Ocean 0
      SH Extra-tropics Land 0.24
      Tropics Ocean 0.26
      Tropics Land 0.26
      North Pole Ocean 0.32
      North Pole Land 0.33
      NH Extra-tropics Land 0.40
      SH Extra-tropics Ocean 0.41
      NH Extra-tropics Ocean 0.47

      These would seem to suggest that the TLT over the extra-tropics oceans are the largest sites of longer-term persistence.

    • bdgwx says:

      Peter,

      I’m not following you. The UAH global TLT trend is +0.1367C/decade +-0.0067 which is statistically significant by a large margin.

      Remember that climate forcing agents (like CO2 or whatever) perturb the Earth Energy Imbalance (EEI). It is the net effect of all perturbations that dictate the final EEI and the final accumulation/depletion of heat in the geosphere. In addition there are several mechanisms that work on varying time scales that transfers heat from one reservoir to another. There is no expectation that CO2 (or any single climate forcing agent) should track the TLT trend exactly. Though the long term trend of the UAH global TLT is positive (not stationary) as is CO2 concentration so…

      What statistical technique are you using to get the coefficients of 0.45 and 0.43? I’d like to understand more about what you’re looking at here.

      • Peter Hartley says:

        The analysis treats all the series as stochastic without deterministic time trends. Use L to denote the lag operator. For a time series X_t, LX_t = X_{t-1} and L^kX_t = X_{t-k}.

        A time series that is growing over time, like the Mauna Loa CO2 monthly values, is non-stationary if it has a random walk component, for example, X_t = X_{t-1}+\epsilon_t or (1-L)X_t = \epsilon_t. Such a random walk component is known as a “stochastic trend” if \epsilon has a non-zero mean. The series X_t is also said to be integrated of order 1 if (1-L)X_t is a stationary time series, integrated of order 2 if (1-L)X_t is not stationary but (1-L)^2X_t is stationary, and so on.

        A time series that is integrated of order d for d integer can often be modeled as an ARMA process
        \rho(L)(1-L)^dX_t = \theta(L)\epsilon_t where d is an integer,

        \rho(L) = 1 – \rho_1L − \rho_2L^2 − … − \rho_pL^p with the roots of the polynomial
        \rho(z) = 1 – \rho_1z− \rho_2z^2 − … − \rho_pz^p = 0 lying outside the unit circle

        and \theta(L) = 1 + \theta_1L + \theta_2L^2 + … +\theta_qL^q with the roots of the polynomial
        \theta(z) = 1 + \theta_1z + \theta_2z^2 + … +\theta_qz^q also lying outside the unit circle.

        A time series is said to be fractionally integrated if instead -0.5 < d < 0.5. These processes have a "long memory", but not as long as random walks were the "memory" is "forever". The higher the value of d, the longer the memory.

        As I mentioned in the first post, many climate variables are fractionally integrated. It turns out that this is the case for the UAH TLT temperatures.

        On the other hand, monthly average CO2 from Mauna Loa is integrated. In my opinion, this is consistent with at least a partially human driver of the CO2 (emissions are related to GDP, and that is integrated, so the CO2 series inherits that integration).

        My point about what this says about climate models is that if we have

        ∆T = k_1∆Forcing = k_2∆CO2 where k_1 and k_2 are constants (effectively a linear relationship between CO2 and temperature) then if the CO2 series is integrated so should the temperatures be integrated. However, that is not what we find. To me that means a simple linear connection between CO2 in the atmosphere and TLT is strongly inconsistent with the data. Furthermore, there does not even yet appear to be strong evidence that TLT are non-stationary, as they ought to be if they are driven by non-stationary economic processes (which economic growth is) through some other mechanism.

        The other finding I emphasized is the the "length of memory" in the TLT temperatures varies across the globe. There seems to be more persistence (longer-term feedbacks operating, but still not permanent change) in the extra-tropics oceans, extra-tropics land and to a lesser extent the north pole. Then comes the tropics and southern hemisphere extra-tropics land, which appears to operate more like the tropics than the northern hemisphere extra-tropics land. Curiously, the south pole TLT does not appear to have any "long memory" process at all — maybe because it is somewhat isolated from the rest of the globe by circumpolar air flows?

        • bdgwx says:

          Thanks Peter. I’m somewhat familiar with stochastic analysis, but pretty weak at it. When I get time I’ll see if I can’t get more up to speed on these techniques.

        • Jeff T says:

          @Peter Hartley, It appears that you are using the lack of obvious month-to-month changes to claim that the average UAH temperature anomaly in the 2010’s is not really higher than it was in the 1980’s. If you processed daily anomalies instead of monthly, your conclusion might appear even stronger; but it would be equally senseless. Please average the data over a year or two or three and repeat your analysis.

          No one is claiming that CO2 is responsible for every fluctuation of global temperature anomaly. Instead, the claim of most climate scientists is that increases in global CO2 are primarily responsible for a trend of increasing anomalies that are clearer as one averages data over longer periods. That trend is apparent in the 13-month running average of Dr. Spencer’s plot and is even more apparent when the averaging period is longer.

          • Peter Hartley says:

            Jeff,

            Just to clarify, I am not using month to month changes — I am looking at the whole sample of 501 months of data posted at the link to the UAH web site that Roy gives. I also am not comparing averages in the 2010’s to averages in the 1980’s. I also am not looking at trends in moving averages of the UAH data. Implicitly, these techniques assume there are deterministic trend components in the time series. My approach instead treats them as entirely stochastic. I am simply trying to characterize the type of stochastic process that the temperatures appear to be following.

            Such an exercise is a different way of summarizing the properties of the data. It is useful for checking theories because the theories have to be consistent with the stochastic properties of the data sets. In particular, two series linked in a linear functional relationship should display the same levels of integration. If they do not, they cannot be so linked.

            In this case, the very different properties of the CO2 series and the temperature series imply that there cannot be a simple functional connection between CO2 and temperature.

            Interestingly, if one looks at the CO2 series in more detail it turns out that the fluctuations at the annual frequency are also integrated. This shows an example of what I am talking about. As CO2 content in the atmosphere follows a stochastic trend, the seasonal fluctuations due to NH deciduous vegetation uptake in the spring and release in the fall are also trending over time. More CO2 leads to more deciduous vegetation, which in turn leads to larger seasonal fluctuations. The time series properties of the series are consistent with the theoretical link.

            Going back to the TLT, the other thing that is revealed by the analysis is that the longer-term persistence in TLT appears to be focused on the atmosphere over the NH extra-tropics ocean and to a lesser extent the NH extra-tropics land and SH extra-tropics oceans. Since I presented the fractional integration parameters above, I have now also modeled the short-run dynamics and the persistence levels have declined a little but the ranking remains similar to what I found above above. For the fractional integration parameters, I now get:

            South Pole Land 0.0
            South Pole Ocean 0.0
            Tropics Ocean 0.260
            Tropics Land 0.261
            North Pole Ocean 0.266
            SH Extra-tropics Land 0.322
            North Pole Land 0.325
            SH Extra-tropics Ocean 0.360
            NH Extra-tropics Land 0.387
            NH Extra-tropics Ocean 0.427

            In actuality, that’s close to the truth. UAH, in it’s 33 year report claimed little or no warming till the 1998 El Nino. I interpret that to mean there was little in the way of anomalies above the baseline. The 98 EN drove global temps suddenly above the baseline almost a full degree C.

            Following the 98 EN came a lengthy flat trend till about 2015. The year 2010 had another significant EN yet the average remained about 0.2C above the baseline.

            You have to be aware that the trend pre 1998 was made up mainly of negative anomalies, not true warming, which requires positive anomalies.

        There is no such thing as a climate forcing agent. That is climate model theory based on unvalidated models and forcings apply only in models as mathematical forcing functions. Climate is an average of daily weather and the weather is driven basically by solar energy.

        Weather, hence climate, involves atmospheric gases but there is not a shred of proof that a trace element in atmospheric gases, CO2, at 0.04% of the gases, is driving the temperature of those gases. That is contrary to the Ideal Gas Law. The major gases, N2 and O2, making up 99% of the atmosphere control the temperature.

        The top graph is the GFS analysis+forecast anomaly vs the CFSR 30 year average from 1981-2010. The analysis is to the left of the dotted vertical line and the 7-day forecast is to the right.

        The graph underneath it is the GFS 7-day forecast bias relative to its own analysis. It is essentially assessing the skill of the GFS 7-day forecast. The GFS has a well known cold bias on forecasts especially for the SH. And as you can see the bias is pretty substantial. The cold bias increased quite a bit last year when the FV3 numerical core and newer parameterization schemes were implemented.

        It is important to note that “analysis” and “reanalysis” while similar conceptually are not the same thing. The GFS is not designed to measure the global mean temperature nevermind produce a stable measurement of it that is consistent over long periods of time. The GFS is primarily used as an operational weather forecasting tool. Tradeoffs are made such that its skill in operational meteorological forecasting is given priority over skill in measuring climatic parameters. You’ll want to stick with bona-fide “reanalysis” datasets for climatic data analysis. The site does have the NCAR reanalysis dataset.

    • bdgwx says:

      Tor,

      Different things are being measured. UAH TLT is pretty high up in the atmosphere as opposed to the surface temperature which is only 2 meters above. Monthly troposphere temperatures can and often do move opposite that of surface temperatures even though there is a positive correlation over long periods of time.

If NOAA is getting the data before UAH then passing it on, there is nothing to stop them fudging it upward using some kind of algorithm.

      I don’t think that is a conspiracy theory. We know they have extensively fudged the surface record, for reasons unknown, seemingly political, and they have the technology to ‘adjust’ sat data anyway they want since it’s their sats and their telemetry.

          I would also note that all those groups above aren’t a conspiracy. Thus any discussion of them as a group shouldn’t be considered a ‘conspiracy rant’, either. Now an ‘indoctrination rant’ would seem to be at least realistic.

          We are very clearly in a data fudging era. And I am not talking about intentional or necessarily conscious fudging. Never seen that in my area of examination. But still have had numerous findings. The non-conscious fudging is at least an order of magnitude greater than the conscious fudging among people who have worked hard to get where they are. And for all kinds of fudging its several orders of magnitude in the direction of either direct money or fealty toward the dispenser of the money. And it doesn’t have to be a lot of money it can be as little as an regular or occasional cup of coffee as long as its relatively larger than other inducements.

          So data fudging automatically arises out of an impassioned search for the truth already believed in.

            It’s not stopping in the atmosphere and it’s not coming out of the oceans:

            * K. von Schuckmann et al.: Heat stored in the Earth system

            The study obtains a consistent long-term Earth system heat gain over the period 19712018, with a total heat gain of 358 +/- 37 ZJ, which is equivalent to a global heating rate of 0.47 +/- 0.1 W m-2.

            Over the period 19712018 (20102018), the majority of heat gain is reported for the global ocean with 89 % (90 %), with 52 % for both periods in the upper 700 m depth, 28 % (30 %) for the 7002000 m depth layer and 9 % (8 %) below 2000 m depth.

            Heat gain over land amounts to 6 % (5 %) over these periods, 4 % (3 %) is available for the melting of grounded and floating ice, and 1 % (2 %) is available for atmospheric warming.

            Our results also show that EEI is not only continuing, but also increasing: the EEI amounts to 0.87 +/- 0.12 W m-2 during 20102018.

            The amount of CO2 in the atmosphere would need to be reduced from 410 to 353 ppm to increase heat radiation to space by 0.87 W m-2 , bringing Earth back towards energy balance.

            Where in the world Svante did you ever get the idea that heat might be coming out of the oceans?

            ============================

            Well you may have gotten that from me but that would be due to your misunderstanding of everything i have said about the dynamics of internal variation via ocean oscillations. And I have said plenty, if read properly, to come to the completely opposite conclusion.

            1) I have only ever discussed any dynamics on the PDO and ENSO.

            I have had people many times point out (can’t remember if you were one) that the PDO index isn’t an index of increasing ocean temperatures, which I have agreed with every single time. In fact, efforts are made to detrend the PDO data.

            2) I have explicitly said I wasn’t certain how the PDO affected world climate but have merely noted it is highly correlated with it. Thus one explanation, and the one I find the most plausible in the absence of another finding, is that ocean storm tracks do move when the PDO moves. That results in longer trips across the Pacific for storm systems. Wind is a huge variant in evaporation as shown when you blow on hot food to cool it. thus the injection of water vapor into the atmosphere (which I consider to be the largest by far possible avenue for additional greenhouse warming – considering water vapor is not uniformly distributed in the atmosphere) could be a likely explanation for the correlation. Now technically thats removing heat from the ocean but only temporarily as it falls back within days and it seems likely to have no impact or de minimis impact on ocean heat content, which at a minimum renders your claim as rather absurd.

            3) the above recognizes as I have regular recognized effects from a greenhouse effect. And its also due to the fact its clear that water is not saturated in the atmosphere completely consistent with a single layer GHE philosophy.

            4)I have never studied the AMO. I really don’t know anything about the AMO beyond believing its very possibly a key ingredient in the comings and goings of Arctic ice because it is one of two major pathways for maintaining cold ocean bottoms. This infusion of cold water into the deep ocean would have possibly large impacts on ocean heat content over time. But there is no sense in talking about it because we don’t measure ocean heat content at the bottom of the ocean.

    b,

    You do realise that EEI is just alarmist gibberish, dont you?

    Unless you have a magic one way insulator which allows more total energy to pass unidirectionally, of course! The climate dills at NASA apparently believe in such a thing, but of course it only exists in their imaginations.

    • Gordon Robertson says:

      swenson…”You do realise that EEI is just alarmist gibberish, dont you?”

      It’s based purely on radiation theory and radiation is known to be a minor player at terrestrial temperatures. In other words, it is not a good means of heat dissipation at those temperatures. If it was, home-builders would not be as focused on preventing heat loss by only conduction using insulation like R-rated insulation.

      EEI disregards several complex means of heat retention and heat loss on the planet. Furthermore, Trenberth and Kiehl, who wrote the nonsense admitted they had no scientific basis for the theory. You can see that when they have back-radiation for GHGs transferring as much heat back to the surface as what is dissipated via radiation.

      I lost any respect I had for Trenberth when he was caught in the Climategate email scandal admitting the warming has stopped and it was a travesty that no one knew why. Then he interfered in peer review while his IPCC partner as a Coordinating Lead Author, Phil Jones, claimed he and ‘Kevin’ would ensure that certain skeptical papers would not reach the review stage. I think one of those papers was co-authored by John Christy of UAH.

      Alarmist scumbags!!!

      • E. Swanson says:

        Gordo tosses out another of his science denialist rants. For example, he wrote:

        If it was, home-builders would not be as focused on preventing heat loss by only conduction using insulation like R-rated insulation.

        It’s well known that reflective insulation layer reduces radiant heat transfer under a roof.

        Not to mention the fact that the UAH data analysis is based on the same theory of radiation heat transfer in the atmosphere, though at a longer wavelength band in the microwave than the emission bands of CO2 and H2O which provide the Green House Effect. Of course, he ignores the fact that the surface loses thermal energy thru convection, in addition to radiant HT, so there’s no reason to expect that the upwelling IR must equal the downwelling IR.

        ALL…as in 100%…of Earth’s heat dissipation is via radiation. It is the ONLY means of heat dissipation at terrestrial temperatures or any temperature for that matter. That is the exact opposite of “not a good means of heat dissipation”.

        • Midas says:

          There is one other means, albeit insignificantly small.
          The escape of gases from our atmosphere into space.

          • MikeR says:

            Bill,

            Yes you are 100% correct.

            I should have not have made fun of DREM and his predeliction for repetitive four word commentary via cut and paste.

            DREM’s periodic outbursts of PSTs are clearly a sign of a superior intellect.

            How did I not realise this and that you are such a fan of his contributions?

          • bill hunter says:

            Trolling does seem to be a rather enthusiastically pursued occupation around here as opposed to actually discussing the issues. Seems legitimate to point it out when it’s occurring. If it’s not trolling a well reasoned argument should make that apparent. But I think that’s probably exactly what DREMT is suggesting.

          • Svante says:

            bill, MikeR gives everyone the respect that deserve.

          • MikeR says:

            Bill,

            I don’t know why I find DREM’s outbursts of PSTs so irritating. Maybe it’s the repetitive vacuous natureof them.

            The first time might have been, in the eyes of some , slightly amusing , to others slightly offensive. By the 2000th time (rough estimate),the charm has worn off leaving just offensiveness

            Bill, do you find them entertaining, intelligent, witty, perhaps worthy of Oscar Wilde?

          • Dr Roys Emergency Moderation Team says:

            Perhaps you find them irritating because you are a troll, but are in denial about it.

            I’m not in denial about anything. I’m fully aware that there are several people here who consider me a troll, and I understand why. They’ve lost a few arguments to their intellectual and moral superiors, they start getting upset, I start correctly asking those who are trolling to stop, and in their agitated state they consider that an act of trolling in itself. I get it.

          • bill hunter says:

            Bill,

            If you want to introduce a manhood pissing contest ( apologies for another allusion to a pungent topic) then yes, I doubt if I could win.

            At my age and hevresultant BPE, I probably couldn’t compete unless he has a indwelling catheter.

            I am also terrified by the impressive intellectual cod piece that DREM brings to the table.

            One prick and it reveals an intellectual vacuum underneath. An imploding troll would surely be a sight to behold but I might be severely concussed by the force of the implosion.

            Yes Bill, pissing contests are well known around these parts.

            I have no idea why you are rushing to the defence of the uber troll, if you are genuine with your concerns about trolling.

            I must have missed it. I thought he might have been slightly saner. Oh well it explains a lot.

          • Svante says:

            Confused as always, but bill hunter says:

            The moon does not coincidentally rotate in time with the period of its orbit. Thats my take on what DREMT believes. You will have to ask the other people because I don’t know.

            I told him to fill a big bowl with water and let small bowls float around the edge. He insisted they would face inward as the big bowl rotated, just like DREMT thinks.

            DREMT spilled the water all over, but bill insisted it was the Coriolis effect that forced the small bowls to keep to the inertial reference frame.

          • Dr Roys Emergency Moderation Team says:

            Svante, MikeR, please stop trolling.

          • bill hunter says:

            ditto. Svante obviously you believe the moon coincidentally rotates in perfect time with its orbital rotation and in complete denial of cause and effect.

          • Svante says:

            So the Moon does not rotate.
            You have graduated with a lowercase ‘z’.

          • Dr Roys Emergency Moderation Team says:

            The moon does not rotate on its own axis, i.e. about its own center of mass. That is what is being argued. The moon does rotate, about the Earth/moon barycenter. This is known as “orbiting” or “revolution”.

          • Svante says:

            Whatever.

          • Svante says:

            But as Tim Folkerts pointed, nothing rotates on its own axis.
            It has to be in relation to some frame of reference.

          • Dr Roys Emergency Moderation Team says:

            The Earth rotates on its own axis.

          • Svante says:

            OK, let’s agree on that.

          • Dr Roys Emergency Moderation Team says:

            OK, Svante.

          • Svante says:

            With respect to the inertial reference frame.

          • Dr Roys Emergency Moderation Team says:

            From any reference frame, the reality is that the Earth is rotating on its own axis. You may be able to think of a reference frame in which it appears not to be, sure.

    You wrote above:

    ” Yes, I agree that short term different trends may be fully ‘normal’. But UAH has had the southern hemisphere as warm as the northern since may/june.

    In contrast, if you plot a 3 month period (ie. june, july, august) for NOAA, land and ocean, the northern hemisphere for 2020 comes out as the warmest, at 1.17 C, while the southern hemisphere is only 0.67 C and at 4.th place. ”

    *
    I’m always wondering about such trials to deduce something valuable from so little data.

    Here is the comparison, for UAH6.0 LT, of the two hemispheres:

    https://drive.google.com/file/d/11iNbVZZAouWgXVz7mBP214SARHhY6mem/view

    Source:
    https://tinyurl.com/y4ln5u9t

    Below the NH and SH plots, there is a plot of their differences (which were displaced by -1.1 to avoid them interfering with the data out of which they were calculated).

    You see above all that it not so very useful to concentrate on two or three differences around 0.02 C when these in fact span over [-0.63 : +0.65].

    But you see as well that the differences were mainly negative before about 1996, and moved then to positive values, what means that before 1996, the UAH SH anomalies were on average surprisingly higher than those in the NH.

    Last not least, the comparison might be interesting in so far as while in the NH the difference between 2015/2016 and 1997/98 is positive and very high, the inverse happened in the SH: there, the difference between the LT reactions on the two El Nino periods matches the differences between the ENSO signals in the MEI index (2015/16 was about 85 % of 1997/98).

    Because the changes observed since the early 20th century are not a rebound. Left to natural climate processes Earth would have continued cooling at the same rate as the last 5000 years.

    http://railsback.org/FQS/FQS22katoFutureTemps03.jpg

    Instead we have artificially upset the balance in favour of accumulating heat and are now warming as a result of our own activity.

    • ren says:

      Do you think we can compete with solar energy? Also with the magnetic energy of the solar wind?

      • RICHARD WHYBRAY says:

        It’s not the energy we produce which is the problem we only produce 15 terajoules /year.

        It’s the 300 zettajoules/ year the planet is soaking up because we’ve upset the energy balance.

        • Swenson says:

          RW,

          Rubbish. You cant get anything to soak up energy, on a yearly basis, on the Earths surface. After the sun goes past the zenith, things start to cool down. Even worse, the elliptical orbit and axial inclination of the Earth cause seasons. No soaking up. No accumulation.

          Put a sealed container of water outside in the sunlight. You cant even get it to soak up enough energy to boil! Not even if you let it soak up energy for a hundred years!

          • skeptikal says:

            Swenson says:”Rubbish. You cant get anything to soak up energy, on a yearly basis, on the Earths surface.”

            Sure you can… it’s called ice. Ice must absorb energy in order to melt. A glacial retreat is ice soaking up energy on a yearly basis.

          • bobdroege says:

            Swenson,

            “Put a sealed container of water outside in the sunlight. You cant even get it to soak up enough energy to boil! Not even if you let it soak up energy for a hundred years!”

            You want to make a bet on that?

          • Swenson says:

            s,

            A glacial retreat is lack of precipitation. Nothing to do with absorbing more energy than it emits. Antarctic ice close to the pole gets six months continuous sunlight. No soaking up, no accumulation. No melting.

          • Swenson says:

            b,

            Absolutely. Now you can pretend to be a smart donkey, and tell us about your magnifying lens, parabolic mirror, electric heater, or any of the other idiotic things alarmist donkeys present trying to overcome the laws of thermodynamics.

            I have never lost a bet against a stupid donkey. What are your hidden conditions? Do I really have to include no additional heat source, and only the unconcentrated rays of the sun? And so on?

          • bobdroege says:

            Yes Swenson,

            No additional heat source, no parabolic mirrors, no electric heaters.

            I can still do it.

            Still want to bet?

            Hint the word is still!

          • Swenson says:

            Yep. Unconcentrated sunlight only energy source. Sealed container of water. Go for it. Provide proof of your measured temperatures.

            Imaginary experiments or models dont count.

          • bobdroege says:

            I missed the sealed container part, which makes it impossible, without breaking the container.

            So I will launch it into orbit, still outside, still in the sunlight and crash it into an asteroid, where the container will break and all the water will boil.

            Silly answer for a silly question.

          • Swenson says:

            b,

            It seems like you missed the *imaginary experiments . . . dont count* bit, too. Donkey.

          • bobdroege says:

            Then there is another answer, connect a vacuum pump to the sealed container and evacuate until the contents start boiling.

      richard…”Left to natural climate processes Earth would have continued cooling at the same rate as the last 5000 years”.

      That would be fine had we not endured a mini ice age called the Little Ice Age for 400 years, It cooled a lot faster during that time and we are slowly returning to whatever the norm was before the LIA.

            ===============================
            the please stop trolling message is rich in meaning MikeR.

            A troll is a person who posts unresponsive messages with no rationale for the sole purpose of being a pest.

            It comes from mythology where trolls ate farmer’s goats. It places you in the same category of pests as a ground squirrel is to a gardener.

            therefore when a response in a debate is effectively the sound of somebody stomping his foot that’s being a pest, intellectually dishonest, non-responsive, or designed to offend.

            So if you are having a hard time remembering all that in a single one line message I can certainly oblige an old codger like yourself and compose some longer text if you desire to let you know that your last post wasn’t at all helpful nor did it appear to be intended to be helpful.

            PST is obviously not a troll. . . .its sole purpose is to end trolling. If I post a PST on a post where you disagree that the intent of the targeted post was indeed helpful the reasonable response would be to explain why the targeted post was labeled a troll incorrectly.

            I am in here to discuss the issues, share my perspectives, learn, and debate. If you don’t like that FU! Just don’t read or respond to my posts.

            Bill, so PSTs are an effective method for controlling trolls?!

            That’s why the PST has been repeated thousands of times by DREM?

            and Svante why not a recovery bigger than the decline? after all we just went through a record breaking solar grand maximum

          • Svante says:

            bill,
            Your comment is in the wrong place, but I assume you are talking about “LIA recovery”. It means a temperature increase without a cause. First a perturbation away from equilibrium, then a return. The further from equilibrium, the stronger the correction, less strength the closer you get to the old value.
            So we would expect a flattening of the curve as we approach the old value. Instead we got an acceleration as we exceeded the old level.

            “a record breaking solar grand maximum” is a direct cause, so that is different.

            ============================

            Yes in general one would expect at least a small diminishment under say a general increase in insolation as that effect slowly melted ice and warmed the deep ocean. But these are not short term processes and its rather inconclusive that late 20th century warming was faster or slower than early 20th century warming.

            The fact that cooling climate change occurred between the two just adds to the mystery rather than subtracts from it.

            The ‘mixing’ zone in the ocean warms quickly because the waters do mix. Then mix from the heat added into the photic zone of the ocean creating convection, and winds, and tides.

            Below that for 90% of the ocean is the aphotic zone of the ocean consisting of unique currents that have been moving for over a thousand years without substantial mixing, with substantial mixing determined by a inability to date the water.

            ===========================

            Indeed and essentially adding an confounding element whereby one may not expect any slowing in warming. You got feedbacks and you have recent solar activity primary effects. . . .enough perhaps to actually increase the imbalance naturally.

          • bill hunter says:

            Svante says:

            Heres the net effect since 1750:
            =============================

            The correct way to put that is “our best estimate of the net effect since 1750 if and only if the highly sensitive versions of control theory from a mean estimated from a wide range of models is correct.

            Observations (all current temp records) conclude to various degrees that level of sensitivity is incorrect and thus the chart is in need of change. However, since the chart was designed to support political objectives thats the way it was looking when published.

            You need at a minimum to distinguish between political science and real science.

          • Svante says:

            Your solar idea is still an order of magnitude too small.

          • bill hunter says:

            Another argument from ignorance. The correct and intelligent way to term that Svante and not look like a dumbass in the process is to say ”Your solar idea may be an order of magnitude too small.”

            But on the other hand one can equally say: ”your carbon idea may be an order of magnitude or more too large”

            So who taught you that stupid idea?

          • Svante says:

            Increased solar power delivery at the surface would flow upward and warm the atmosphere all the way to the top.

            You think it will create an enhanced greenhouse effect instead, and clouds to take away the surface input at the same time? Shall we call it the pretzel effect?

            Except there is no evidence of increased solar input. In space or at the surface.

      tim…”Not helped by the Covid1984 hoax. Regards Tim”

      It is a hoax, Tim, not with an intent to deceive but based on a belief in seriously bad, unproved science. The premise of covid, as with HIV, is that we cannot find the virus but we believe its there and a lot of scientists agree in the belief. In lieu of actually isolating it and seeing it on an electron microscope, we will infer that certain strands of RNA come from a virus.

      I am not saying it’s there, or it’s not there, I don’t know and I don’t care. I am saying the science behind it is dreadful just like the anthropogenic theory. Whatever is behind the contagion, it has not killed more than 0.06% of people in any population, hardly the basis for declaring a pandemic and depriving people of their democratic rights.

    Dr Roy,
    I posted the following at the article on Mid West Temperatures vs UN Models. I’ve been told that you don’t look at posts in the later stage of a blog, so I’m re-posting it here with the hope that you see it.

    September 30, 2020 at 8:20 AM
    Dr Roy,
    The NOAA web site says that the average temperature for the earth has increased at a rate of 0.18c/decade since 1981. it further states that in 2019 Central North America was the only pocket of cooler than average land temperatures.
    Your graph for the US Mid West shows a rate of 0.08c/decade. Is Central No. America that much cooler than the rest of the world or is there something up with the NOAA data?
    Would it be possible for you to do a graph similar to the one in this article with NOAA overall observations for the average earth’s temperature compared to the CHIP model?
    Tom

    Thanks for your good work.

    • Gordon Robertson says:

      tom t…”Your graph for the US Mid West shows a rate of 0.08c/decade. Is Central No. America that much cooler than the rest of the world or is there something up with the NOAA data?”

      As you say, Roy may not see your post at this stage. I have not seen him around much in this thread anyway. Hope he is OK.

      There is something seriously up with NOAA. They have been fudging surface data since 1990 and since that year they have discarded 90% of their ‘reporting’ surface stations (GHCN). After the IPCC reported 15 years of a flat trend from 1998 – 2012, in AR5, NOAA retroactively fudged the SST to show a trend.

      It’s very well documented on this site, how NOAA and NASA GISS have accomplished the fudging.

      https://chiefio.wordpress.com/gistemp/

      If you read through the entire site you will see info on NOAA, GISS, Had-crut, GHCN and NCD-C.

      Once reason the sat data is lower has to do with the comprehensive coverage of the sat telemetry which covers 90% of the surface as opposed to about 15% for NOAA. For example, in California, NOAA has only three reporting stations, all near the warmer coast. In the Canadian Arctic they have one…ONE!!!…reporting station covering the entire region. NOAA does not care about colder regions, their focus is clearly on warmer stations.

      The alrmists around here will try to convinceyou that the sat telemetry can only measure a 4 km thick region of the atmosphere. That’s because every one of them is totally ignorant as to how a satellite AMSU unit (telemetry) works.

      • Midas says:

        Now here is what the IPCC ACTUALLY said in their AR5 report:

        “The observed global mean surface temperature (GMST) has shown a much smaller increasing linear trend over the past 15 years than over the past 30 to 60 years. … Depending on the observational data set, the GMST trend over 19982012 is estimated to be around one-third to one-half of the trend over 19512012.

        NO flat trend was reported. Do you ever speak the truth?

  25. Gordon Robertson says:

    bdg…”Im not following you. The UAH global TLT trend is +0.1367C/decade +-0.0067 which is statistically significant by a large margin”.

    You can’t take the stated trend literally over the entire UAH range. It’s a number, nothing more, which includes an 18 year flat trend and before that a trend below the baseline. UAH referred to that trend as showing little or no true warming. That is an obvious reference to the occasional blip above the baseline from 1979 till about 1997.

    How do you explain an 18 years flat trend within the context of a 0.13/decade trend over nearly 40 years?

      Remember the Biblical verse Jeremiah 5:21 (Hear now this, O foolish people, and without understanding; which have eyes, and see not; which have ears, and hear not).

  26. Gordon Robertson says:

    bdg…”ALLas in 100%of Earths heat dissipation is via radiation. It is the ONLY means of heat dissipation at terrestrial temperatures…”

    I see you have absorbed all the bs taught by your authority figures at realclimate and skepticalscience. Why should 100% of surface heat dissipation be via radiation to space?

    Ever heard of the Ideal Gas Law, it equates temperature, pressure, volume, and the number of atoms/molecules in a gas? It tells us clearly that heat can be dissipated in a constant volume when the pressure drops. Guess what happens to pressure with increasing altitude?

    It means heated air can dissipate heat simply by expanding. It has plenty of time to do that during the night hours when solar input is not there.

    Also, the fact that the atmospheric average temperature is a theoretical 33C above what it would be without an atmosphere and oceans, suggests something has caused that average temperature to rise. What could that be, maybe the Sun? So the Sun raises the temperature of the atmosphere to 33C higher than what it could be then it “HAS TO MAINTAIN THAT TEMPERATURE”.

    It cannot maintain that temperature while radiating all the input energy back to space. Sorry…but there is far more to the dynamic nature of the surface-atmosphere relationship than a simple theory of heat in = heat out. A lot of heat is retained, in the surface, the oceans, and the atmosphere.

    That’s why the Kiehle-Trenberth energy budget has to create a fictitious back-radiation to balance the heat budget. They don’t even begin to understand how complex the problem is they are dealing with.

      Which shows us, yet again, that Gordo has no inkling that he understands heat transfer and thermodynamics. It’s flaming obvious that any mass which continually receives some energy input but which does not simultaneously lose energy at the same rate will exhibit an increase in temperature. For the Earth, averaged over the years, the input from the Sun (minus that reflect) must be equaled by the energy emitted out to deep space. Given that the Earth is surrounded by a vacuum, the only path for this energy to leave is via thermal radiation.

      Gordo is either a complete moron or is intent on spreading disinformation about science.

    • Ramona Rivelino says:

      “In a single second, Earth absorbs 1.22 1017joules of en-ergy from the Sun. Distributed uniformly over the mass of the planet, the absorbed energy would raise Earths temperature to nearly 800 000 K after a billion years, if Earth had no way of getting rid of it. For a planet sitting in the near- vacuum of outer space, the only way to lose energy at a significant rate is through emission of electromagnetic radiation, which occurs primarily in the sub-range of the IR spectrum with wavelengths of 550 μm for planets with temperatures between about 50 K and 1000 K.”

  28. CAD says:

    The ocean constitutes the largest heat reservoir in the Earth’s energy budget and so exerts the most significant influence on climate. The rate of heat uptake/release by the ocean is dependent, to a large extent, on dynamic processes controlling air-sea exchange. The exact nature of these processes is debatable; for example it is still unclear if the largest contribution of changes to ocean heat content is due to dynamic changes in the equatorial or the higher latitude oceans. The processes are thought to impact climate from decadal to century and millennium timescales. Superimposed on the overall decreasing trend since Holocene Climate Maximum (~8000 years BP) is significant multi-century variability. For example it may be that the deep Pacific is still adjusting (down) related to the cooling going into the Little Ice Age. This lag suggests that large parts of the ocean interior are not in equilibrium with the recent observed tropospheric anomaly. We have much to learn. There is good reason to suspect that the massive volume and heat capacity of the oceans will mitigate small radiative changes in the atmosphere, and that short-term tropospheric temperature anomalies can be mostly explained by dynamic variations of air-sea heat exchange.

    • bdgwx says:

      What we do know is that the top 2000m of the ocean is taking up a large amount of heat. And a study just recently published revealed that the stratification of the ocean is increasing as well which means vertical mixing of heat and carbon is now being suppressed. That means more heat may be available for transfer to the atmosphere and the ocean’s carbon buffer capacity may be beginning to wane.

      • CAD says:

        The authors appear to omit the possibility that the upper ocean has been gaining heat since well before the 1960s related to net cooling of the deep ocean since the the LIA. Over the period of hundreds of years changes in upper and deep ocean heat content have similar ranges, highlighting the importance of deep ocean dynamics on heat and carbon dioxide exchange at the surface.

          • Swenson says:

            b,

            Nope. The hot water still sits on the surface. Unfortunately for your hypothesis, diffusion ensures that salinity increases, ensuring that the hot water doesn’t sink.

            Even if you force it (by pumping, say), the warm water cools to the temperature of the surrounding water, raising the temperature of the surrounding water, which now being of lower density rises until it is surrounded by water at the same temperature.

      The Little Ice Age lasted from about 1400 to 1850. During that period, global temps were claimed to be 1C to 2C lower than normal. You 2.5C sound close to the range.

      We must remember that the LIA was preceded by the Medieval Warm Period, where temps were claimed to be higher than today. Apparently the ice in Greenland melted enough to allow the Vikings to farm there.

      Naturally, the global average has warmed since then but lo and behold, it is blamed on CO2, a trace gas that makes up 0.04% of the atmosphere. No mention from alarmists about the LIA.

      During the LIA, glacier expanded in a major way and now that they are melting, wouldn’t you know the alarmists blame it on…wait for it…CO2. Sea levels would have been lowered as well and CO2 levels would have dropped since colder oceans absorb more CO2.

    midas…”So you agree the globe has warmed since the LIA.
    So tell me … how does the ideal gas law prevent greenhouse warming, but not prevent this warming?”

    Of course it has warmed since 1850, when the LIA ended. I did not say the IGL prevents greenhouse warming since I don’t think greenhouse warming occurs in the atmosphere. Greenhouse warming involved molecules of air being heated by conduction then trapped by glass when they try to rise. There are no glass walls or roofs in the atmosphere. In fact, as Joe Postma put it, we build greenhouses to do what the atmosphere cannot do.

    The IGL gives a scientific relationship between temperature, pressure, volume and the number of atoms/molecules in a gas. The atmosphere is a gas and the IGL shows that a decrease in pressure of the gas produces a natural heat dissipation vehicle.

    • Midas says:

      There you go pretending that the greenhouse effect in the atmosphere is what actually happens in a greenhouse. It is a NAME, nothing more.

      And it has NOT warmed since 1850. It has warmed since the 1910s, which were colder than the 1850s. That is when the LIA ended.

      And why not say “Of course the LIA ended in the 1910s, when greenhouse warming started to become significant”. You have no reason for the choice of causation, other than your preconceived notion that there is no greenhouse effect.

      So let me ask again … how does the ideal gas law prevent the greenhouse effect, yet not prevent other warming?

      • Swenson says:

        Midas,

        So tell us – why call the greenhouse effect the greenhouse effect if it has nothing to do with greenhouses? NASA disagrees with you. Of course, the climate dills at NASA are as deluded as you, so my question is moot.

        No wonder no-one can come up with a testable hypothesis for something that cannot be described!

            But Woods experiments have been repeated and the results were posted on this site recently.

          • bill hunter says:

            what I have seen are a number of repetitions of Woods that didn’t come up with significant differences. But that is no longer a point of debate at the upper levels of thought on this.

            Dr. Lindzen in particular has noted the necessity of a lapse rate in current thought for the purpose of creating the surface forcing.

            Thus focusing on the Woods experiment is really only useful for educating those who remain uneducated. And of course the scientists concerned about CO2 aren’t interested in recognizing that Woods was right either.

            There is a political cost associated with telling your supporters that they have it wrong. That tends to get them questioning the very authority they were originally believing.

          • bobdroege says:

  37. Gordon Robertson says:

    ramona…”For a planet sitting in the near- vacuum of outer space, the only way to lose energy at a significant rate is through emission of electromagnetic radiation…Pierrehumbert”.

    That might be the case if you had no training in physics, thermodynamics, and chemistry. Pierrehumbert is wrong about the planet continuing to heat without a means of heat dissipation. Atoms and molecules can take only so much heat energy for a certain heat input. They don’t store it as he suggests. Clearly, Pierrehumbert does not understand quantum theory.

    In order for the Earth to reach the incredible temperatures suggested by Pierrehumbert, it would require a nearby star with the means of transferring that much heat. He clearly does not understand thermodynamics, then again, none of the alarmists do.

    Has Pierrehumbert ever noted that the planet is claimed to be +33C above what it would normally be in space with no atmosphere or oceans? Has it not occurred to the rocket scientist that the 33C needs to be maintained once the equilibrium temperature has been established? If you want to maintain that temperature difference you don’t want to radiate a lot of the energy to space. If you radiated away all the daily solar energy, the planet would cool. Without heat storage in the oceans and atmosphere, the planet would cool.

    Why would it need to radiate a lot of energy to space? The ocean, atmosphere, surface system is part of a planet located at the ideal distance from the Sun and rotating at exactly the right speed to maintain the 33C with the same solar input. That system exchanges heat from surface to atmosphere and ocean to atmosphere. The atmosphere acts like a compressible gas, which it is, expanding while the Sun is shining and contracting while it is not.

    Once the Sun has raised the global average by the alleged 33C, all it needs to do is maintain the temperature by shots of solar radiation for several hours a day. When the Sun is not shining, at night, the atmosphere can dissipate the day heat naturally, without radiation.

    The problem with Pierrehumbert is that he’s unable to think in more complex terms required for this kind of dynamic system.

    • Midas says:

      As Robertson illustrates he believes heat is stored in electron energy states of an atom.
      Does the nonsense never end.

      “When the Sun is not shining, at night, the atmosphere can dissipate the day heat naturally, without radiation.”
      Please indicate the means of this dissipation. Is it convection, conduction or phase transition. And where does the heat go?

      • bobdroege says:

        According to Gordon and his understanding of the Ideal Gas Law, the atmosphere expands and takes the heat with it and leaves the Earth.

            You must have missed it then, here is what I have posted about what is the core of the greenhouse effect.

            Here goes, it’s pretty simple really.

            CO2 as a gas emits infrared radiation in three specific wavelengths at a rate determined by the concentration of those molecules in the gas with the required excited states. The concentration of those states being determined solely by the temperature of the gas.

            Some of that radiation then reaches the ground.

            Now if you increase the concentration of the CO2 gas, that above effect is increased which would be the forcing you are looking for.

            So I call bullshit on you saying no one can describe the greenhouse effect.

            that wouldn’t pass an auditor’s scrutiny for a manufacturing company that made soda pop.

            Auditor goes and looks at the books and sees the company has boasted a $3 billion increase in sales and $1 billion increase in profits. So the auditor asks to look at the sales books.

            Manufacturer produces a US Commerce Department report that says the soda pop industry increased its sales by $5 billion in the past year.

            Auditor says: Is that all you got in the way of books?

            Happens all the time and if you don’t have an auditor you might actually think thats good evidence. A classic is a home owner in a big city who owns a home in New York. He wants to know the value of it. So he picks up the New York Times that runs a periodic column on New York housing prices and it reports that the average cost of homes sold in New York was $2,700,000 each. Home owner is now satisfied his home is worth $2,700,000.

            Evidence? LMAO!!! You have a model that can’t imitate natural variation because nobody knows how it operates and so you are going to look at temperature records and confirm your theory on how much warming CO2 is going to cause?

          • Svante says:

            You’re thinking here is like saying the CO2 increase is natural. We know we emit twice as much but that disappears down a hole somewhere, not sure where, and the increase is from somewhere else, not sure where but we’re sure it’s natural.

          • bobdroege says:

            Bill gets busted using the correlation is not causation canard, and then doubles down

            with a Gish gallop of:

            1) models can’t imitate natural variation canard.

            and

            2) nobody knows how models work canard.

            but dear Bill,

            you can get a reasonable estimate of how much warming you will get from comparing the CO2 record with the temperature record.

            still has a lot of uncertainty, but the correlation is positive and if you are careful you can get statistical significance.

            Completely different fields.

            But you think it doesnt matter. It does.

            Just as I, a physicist, am not equipped to tell whether an economist or a liver doctor know what they are talking about, and I know that.

            ================================

            Nate if you have never worked in any of those areas how can you know their examples are irrelevant? I can freely agree that experience in a particular industry is a necessity to understand what is translatable and what is not.

            But what you are ignorant of is I haven’t worked in just one industry. So on one hand I can agree you know nothing of the subject for having never been there but you can’t project your own shortcomings to someone you don’t know who has been where.

            Bottom line is an auditor learns the skills to audit anything. Of course you need a couple of years experience in a field before being an auditor in charge. thus you absorb an effective demotion each time you change industries. But I have never been motivated by money so that hasn’t mattered. I have received education in philosophy, meteorology, biology, architecture, and business. I have experience in outdoors, radiant systems, finance, auditing, and policy making based on science. Other than winning a physics award and scoring above 95% of my physics peers in highschool, I have no physics education. So as auditors learn to do I rely on physics experts. And the truth is even if you are a professional you still do the same thing, or you should be.

            One gets an effective demotion each time an auditor changes industry. But most of us spend most of their time on earth working. Thus I feel its more important to have a passion about your work than make more money which does you no good at all when you die.

            So besides the numeric/statistical/documentation skills that come with auditing, auditors still use expert advice and there is an art to that as well which is 100% translatable from industry to industry. What you want is a variety of expert opinions. Where the opinions don’t agree you can mark down as uncertainties. Its important when you change industries to realize that experts always agree on some stuff and seldom agree on other stuff.

            So I would ask you if you accept expert opinion in a balanced and intelligent way? There is obvious disagreement. Sometimes pinning down the exact nature of that disagreement is difficult but that is the challenge of the auditor has to be a journey if he is going to dispense advice. Its time consuming but very doable.

            Obviously your expertise hasn’t risen to that level yet. Who are you or whom am I to decide that issue? Answer is we both aren’t.
            there are far more qualified physicists out there than you or I.

            But I talk about uncertainty and you talk about certainty so its clear you are ignorant of your own ignorance.

            Whereas I am not. Sure I can misspeak once in a while and I have a favored viewpoint, developed from that list of experiences above but I haven’t even yet revealed what that is much less tried to promote it. I am still working on it hoping I can bring it full circle to a conclusion that can be tested and proven. I’ve done the same thing to NASA I do here and challenged their web developers to put more convincing evidence up than they have up.

            If my government is going to spend trillions on solving a problem I want to know its a problem in need of a solution. I don’t buy the concern of rich environmentalist with a seaside estate worrying about ocean accretion. I have lived myself in that harm’s way almost my entire life. And it didn’t go beyond notice that the Obama’s hocked their children’s future by recently buying into such an estate with their new found wealth. Were they seriously convinced? Nope they are just laughing their way all the way to the bank.

            LMAO, you can’t resist showing how stupid you are Nate can you?

            Is that denial? Yep!

            In your best fake news tradition you just cut out of your quote of mine (Of course you need a couple of years experience in a field before being an auditor in charge.)

            Thats how it works dude. If you change fields you go back into a form of advanced apprentice mode. Beginning apprentice mode is when you leave academia no matter the level of your degree. Apprentice mode is when you learn about the real world rather than the imaginary hypothetical worlds of academia.

            Doctors go through it. Engineers go through it. Lawyers go through it. It matters not if you have Bachelor or a PhD. Of course having a PhD gives you an advanced skill set but you are still just as real world dumb as a green Bachelor degree apprentice.

            After serving as a lead auditor, if you change fields you demote down to assistant lead auditor for a couple of years.

            In auditing you don’t need a degree in the field you are auditing. You just need auditing know how, the math, the standards, and the experience with what you audit.

            On technical issues auditors consult with independent experts.

            And excellent example of how that is done can be found at climate audit.

            Here you have an expert mining auditor auditing climate. He consults experts and plies his trade. His work has been recognized by the National Academy of Sciences.

            A lot of people he has helped go out of their way to not acknowledge that it was his help that caused them to make corrections.

            Phil Jones feared having him audit his temperature records so much he said he would destroy the evidence before handing it over to him.

            Sometimes auditors aren’t liked, but only when somebody really has something to hide.

            We really are nice guys.

          • bill hunter says:

            Nate they don’t vouch for its validity they say its plausible and the only known option.

            I agree with that.

            That doesn’t validate it. There is no proof of causation, there is only proof of mean existence.

            If you have somebody who actually described a proof, which I have been asking for years for, the argument would be over.

            Two of them, Roy and Judith Curry have talked about how the concept is pretty mushy and poorly established. It occupies the null hypothesis as its the only one not disproven. . . .so far.

            Further the actual investigatory work being done by all these individuals avoids addressing that issue. So why question it.

            That fact is the difference between a scientist and an auditor; and is also the difference between academic peer review and audit peer review. Audit standards establish a minimum level of effort in every area where doubt is possible and potentially material.

            In the end auditors are allowed to rely on expert opinion to reach conclusions. But that is a concession necessary to make audits not overly oppressive.

            The doubt about the very foundation of the greenhouse effect is at the current moment is not sufficient alone to forestall action, but larger problems are. Like how much warming will occur (where the investigatory work of all of them are currently centered) as well as the impacts that will occur, which entails decisions that only science can assist in making. Its not even conclusive that more warming isn’t sustainable. All that is is a moral imperative of the environmental movement that mankind has no rights to create change. No GMOs, no nuclear impacts, no pesticides, no herbicides, no chemical residues, no warming, no cooling, no sky coloring, no contrails, no meat, no artificial enhancements, no extinctions, no ash or soot, no guns, no profits, no personal property, no individual rights to life.

            I do recognize that that list isn’t a good description of each and every environmentalist or environmental organization but the thinking is based upon the same basic premises across the board.

            “Two of them, Roy and Judith Curry have talked about how the concept is pretty mushy and poorly established.”

            Roy has always stated the GHE mechanism is real, exists, etc. He is trained in meteorology, and thus fully understands the lapse rate issues you have issues with.

            I assume the same for Judith.

            However she thinks there is a gap between the public explanation of the GHE and the real models.

            This is because the real models require lots of physics and math.

            Thats typical of you Nate. You find an article that essentially says alternative skeptic ideas that have been laid out don’t hold up to close scrutiny. And you broaden it to ”has no apparent doubt” as to the certainty of the mainstream GHE mechanism (as if it were carved in stone like a physical law).

            Nothing unusual is happening here Nate when a political organization determines an issue such as manmade climate change is worthy of billions of dollars in funding to investigate what climate scientist would not be intensely interested in participating? The answer is none. Dr. Curry has selected her role and reasonably believes that the theories laid out by the early scientists is probably the correct model. Which is fine but it hardly qualifies as scientific proof. The entire modeling exercise and you have already acknowledged it as so is for the modeling exercise to become so predictive that it can be accepted as a basis for action. Dr. Curry clearly does not think that to be the case. It remains uncertain and as long it remains uncertain the entire theory is up for grabs.

            We were talking SPECIFICALLY about the basic GHE mechanism. On that she is absolutely clear. It is valid.

            She has other issues with the IPCC. She thinks positive feedbacks are smaller. She agrees with the rest of us that there is uncertainty in the magnitude of feedbacks.

            Different issues.

          • bill hunter says:

            Nate don’t be a moron and not read what the discussion has been about here and what Dr. Curry thinks about it.

            The discussion is about the assumption in climate science that the absorp-tion of radiative flux equals the change in surface temperature, before feedback.

            Thats what I started discussing here, never refuted by you except by declaration. You even tried to include Dr Curry as supporting your position, and I just showed that to be a lie.

            “The discussion is about the assumption in climate science that the absorp-tion of radiative flux equals the change in surface temperature, before feedback.”

            I dont think so, Bill. First of all ‘equals the change in surface temperature?’ makes no sense. No one is saying that.

            You have mentioned feedbacks and their uncertainty. If you stuck with that, Dr. Curry could agree with you.

            But instead you went all Denier on us, and into the whole thing with the GHE mechanism being uncertain, not including convection (it does), there being no way for the TOA to communicate with the surface.

            She would not agree with you on any of that.

            But feel free to change the subject.

          • Nate says:

            “The simplified radiative forcing model that relates the tropospheric radiative flux to the surface temperature requires far too many unwarranted assumptions”

            Yeah. I think that is a reasonable complaint. The magnitude of the surface temp rise should not be assumed to be the same as the TOA temp change.

            But she is not denying that there will be a significant surface temperature rise.

            A proper model, like GCM, is needed to evaluate the actual change. And the feedback’s need to be correct.

            Sheesh Nate I had to erase an entire page of comments on your previous assertions before I arrived here at your current comment.

            Yes this is about the central equation for atmosphere capture of out outgoing IR used in models before feedbacks. Though she isn’t talking about TOA temp change. She is talking about the entrainment of additional IR into the atmosphere and how that radiatively affects the surface.

            Who knows when we will know what a proper model is. Certainly not anytime soon as none are fully documented much less validated.

          • Svante says:

            Until then we can use the best models we have.
            They told us where we were heading forty years ago.

            If you skip climate models and have zero feedback you get 1 C for a doubling of CO2, but we’re already past that for much less than a doubling.

          • bill hunter says:

            Well Svante if we use your new super study and compare it to the Michael Mann hockey stick we are about 3tenths of a degree warmer than the MWP and a blistering 5 hundredths of a degree warmer than the Holocene Maximum. Expand that 5 hundreths to 100 hundredths and you will have my attention.

          • Svante says:

            We are 0.8 C above the MWP if you measure from the edge of the error margin, and 1 C over the average estimate.

            So this is not a LIA recovery.

            By the most generous reading we are just passing through the Holocene max. The Paris agreement attempts to stop it before your “100 hundredths”, but look at the rate of warming:

            ==================================

            so you ascribe to the rot that your mates Nate and Barry just disavowed?

            http://www.drroyspencer.com/2020/10/uah-global-temperature-update-for-september-2020-0-57-deg-c/#comment-532926

            Natural climate does indeed go up and down.

            You do have to realize though that during the Holocene max the arctic was indeed ice free. And since the official line is that entails positive feedbacks it looks like we aren’t really there yet.

            Looking at the ice core temperature record for interglacials I am seeing double and even triple peaks. Also interglacials lasting up to near 50,000 years. You have to be a moron to rule all that out as a possibility. And thats not to speak of .3 tenths of a degree in the long term instrument record trend coincides with the recent El Nino cycle. That needs to play out for maybe another couple of decades.

            I think its at least equally reasonable to conclude we could be in the ballpark of the Holocene max entirely due to natural variation. . . .because we do actually have a track record of that. . . .which of course CO2 theory doesn’t. The CO2 theory remains deficient in both inductive and deductive worlds of logic. Can we solve that problem? I tend to think we can but via an approach that doesn’t depend upon model predictions, historical proxies or any such stuff as that. Over funding all that stuff is just for political reasons not scientific ones.

          • Svante says:

            What do you suggest if it’s not models or proxies?

            http://railsback.org/FQS/FQS800katoFutureTemps01.jpg

            I didn’t know the Arctic was ice free in the mid Holocene.
            Do you have a scientific citation for that?

            I guess there must have been less ice than today, because feedbacks had more time to settle.

          • bill hunter says:

            Yes there are number of geologic studies that establish the arctic was ice free or virtually ice free. Among the most compelling are beaches on the shores of far northern shores that show the type of wave action erosion that can only be accomplished through wave actions generated over ranges of miles that overlap the central arctic. Others include bottom deposit studies which are less conclusive but universal in showing open ice free water during the Holocene. Those aren’t conclusive quite simply because the arctic is not yet ice free and thus there are areas yet to be sampled.

          • Svante says:

            It says:
            “Further north, ridges are short and sporadic, restricted to mouths of embayments and valleys, which suggests that permanent sea ice persisted throughout the Holocene at the northernmost stretch of the coast”.

          • bill hunter says:

            You are right Svante. When I pointed that out about 10 years ago in a discussion as I recall about Mark Serreze prediction of an ice free arctic back from 2007 as occurring in about a decade; I was informed and subsequently confirmed that in climate science – ice free is determined to be less than one million square kilometers of of persistent ice.

            You see the problem is these thick layers of bottom fixed ice that you find around glaciers and shorelines aren’t expected to go away in order to declare the arctic ice free so they allow for the ice extent to remain at one million square kilometers. You need to read up primarily on shoreline geologic studies to determine if the arctic ocean was, as defined, ice free. Those studies rely upon wave power. Large waves need long distances to build up to gain enough power to move big boulders and such. These event occur rarely even in open oceans because it requires massive storms and long distances for big waves to form. Its certainly not an exact science like all proxies but one should look at the data, especially data that isn’t politically controversial, though that process itself brings controversy when it rubs against political narratives. Usually it spawns a host of political science robots to search out contrary information. So keep this low profile, we don’t need more government corruption than we already have.

      The data indicate that the temperature of the planets’ troposphere, with an atmosphere with a mean surface pressure well above 0.1 bar, is dependent on distance from the Sun and pressure at a certain atmosphere level.

          • bill hunter says:

            Svante I have no idea what you are talking about. Your link says this in the conclusion i.e. cooling on the antarctic plateau:

            Our findings cannot be understood as explanation of this phenomena but show remarkable similarities with the observations. . . .
            Yet we showed that for the cold Antarctic continent some care needs to be taken when discussing the direct warming effect of CO2.
            ==================================

            One might not be able to say it more delicately than that.

          • Svante says:

            Your quote is taken out of context. They are talking about earlier work.

            I was wondering if you were happy with their validation of radiative transfer calculations with GHE measurements by satellite?

          • bill hunter says:

            Nice try Svante. I said it was in the conclusion and its in the first person plural.

            Go ahead and don that tin foil hat with the spinner on top again.

          • Svante says:

            Here’s quote with more context:

            The analysis carried out by Chapman and Walsh [2007] and Steig et al. [2009] did not result in any statistically significant surface temperature trend on the East Antarctic Plateau during the last decades. They even found a slight (but statistically not significant) cooling trend for the centre of Antarctica. Our findings cannot be understood as explanation of this phenomena but show remarkable similarities with the observations.

            Are they talking about earlier work maybe?

          • bill hunter says:

            No!

          • Svante says:

            What do you think the word “this” refers to then, if it’s not the findings by the 3rd person plural?

          • bill hunter says:

            Svante says:
            October 13, 2020 at 4:22 PM
            What do you think the word this refers to then, if its not the findings by the 3rd person plural?
            =========================
            By pronoun reference rules it refers to: ” slight (but statistically not significant) cooling trend for the centre of Antarctica.” found in the preceding sentence.

            Instead of getting so worked up over it and playing quiz games why not just come out and say what you think>

          • Svante says:

            I think it refers to the preceding sentence:
            “They even found a slight (but statistically not significant) cooling trend for the centre of Antarctica.”

            And “They” refers to “Chapman and Walsh [2007] and Steig et al. [2009]” in the sentence before.

            Which is earlier work like I said.

            Now the question I asked was if you were happy with their satellite validation method when you analyzed their paper.

          • bill hunter says:

            I haven’t read their paper. I read the conclusion to see if it was something I should read.

          • bill hunter says:

            this is pretty serious stuff Svante. Think seriously about it for a moment.

            Your kindergarten model proposes a forcing on the surface based upon CO2 evenly distributed in the atmosphere.

            Thus the forcing should be the same everywhere according to the kindergarten model. Yet you have two studies that show that the Antarctic has no warming and in fact cooling with increased CO2.

            All you have do now is do what climate scientists do routinely and just extrapolate your arse off. that means there is no greenhouse effect above the Antarctic. Is that a violation of physics laws Svante?

            Obviously there must be something else about this greenhouse effect we haven’t figured yet.

            So you link to a study to explain this and the authors themselves disclaim it as an adequate explanation. And further add a warning to assume that the ghe is as simple as advertised.

            Now I could take the time to read their study but why? I am only interested in answers with high levels of certainty. I am not interested in the study for the purpose of what most are interested in such studies that work in climate science, namely figure out how it does actually work. For somebody trying to do that that might be useful. For somebody like you what is it? Some way to feel better that there might be an explanation?

            I guess that figures that if you need 3 variable that need to come together and each is about 1 chance in 3, then you add all that up and get 100%?

          • bill hunter says:

            what it really adds up to is one chance in 27.

          • Svante says:

            It’s kindergarten simple, why can you not understand?
            There is no GHE without a positive lapse rate.
            There is a negative GHE with a negative lapse rate.

            That is because higher temperature means more radiation.
            What matters is the temperature where radiation leaves for space, the temperature that you see (in IR) from space.
            Higher temperature, more IR loss to space, and vice versa.

            Fig. 4 gives you the global picture of the varying GHE.

            Thats really interesting Svante. So the colder the atmosphere the greater the backradiation?

            I will have to plug that idea into the kindergarten climate model.

          • Svante says:

            That’s right, if the space interface cools everything inside of it will warm up. Back radiation is only part of the story.

            There must be equilibrium at the surface, at TOA, and everywhere in between. Until we have that, temperatures will go up.

          • bill hunter says:

            Correction: Until we have that temperatures will go up or down as they always have and always will. Fact is the problem, if its a problem, will only ever cease after we are all dead and fully rotted away.

            Pretty compelling argument that you have your head in the clouds.

          • Svante says:

            Yes, temperatures have always changed.
            Always changed for a reason.
            Today it’s a very strong reason: GHGs.
            You don’t care because you are dead soon.
            That’s inconsiderate and impolite.

          • bill hunter says:

            Svante I agree temperatures change for a reason.

            As we continue to work on understanding how climate changes we will get better at predicting it. We aren’t very good now when we have to after the warming has occurred go down range and move the target into the spot the bullets hit. That’s the Texas Sharpshooter fallacy.

          • Svante says:

            We were good enough at prediction fifty years ago, and 150 years of history is telling us how it works:

            Some hope that though it might not take as long if you look at ice core records recoveries from glacial periods take a lot less time than the plunge into the glacial takes. It would be good to have a hypothesis that produces that pattern, but alas we don’t.

            Remember Dr Pierrehumbert said energy input so not heat, so I don’t see what laws of physics would be violated.

            Other than the ones already violated by his statement of if the earth couldn’t get rid of the heat.

            It’s been long enough. If any of the idiots could recognize the problem with the bogus 800,000K, they would have said something by now.

            A “thought experiment” is used frequently to make a point. It’s usually easy to understand, and has a valid purpose. The problem arises when it is used to pervert science. A thought experiment can NOT violate the laws of physics. If it does, it is invalid, bogus, and corrupt.

            Pierrehumbert’s “800,000K” nonsense is an example of perverted science. He allows no energy to escape Earth. That’s impossible.

            Pierrehumbert then goes on to require Earth to continue warming even after it has reached the maximum temperature for the incoming flux. That’s not how it works, and violates the 2nd Law of Thermodynamics.

            The concept of a perfectly insulated containers that allow no heat to escape is hardly more extreme or perverted that any of the other idealizations listed. Pretty much every calorimetry problem in freshman physics, engineering, or chemistry makes this assumption.

            “Pierrehumbert then goes on to require Earth to continue warming even after it has reached the maximum temperature for the incoming flux. “

            That is actually not 100% clear in original article. (https://geosci.uchicago.edu/~rtp1/papers/PhysTodayRT2011.pdf)
            In one interpretation, the energy is sunlight. In another interpretation, the energy merely needs to be 1.22 x 10^17 J. It is perfectly possible to interpret the sentence to merely mean an amount of energy, in which case there is no ‘temperature for the incoming flux’ to compare with.

            Look, I agree it is a kind of silly calculation, taken to a silly extreme. I would have preferred 800K in 1 million years to 800,000K in 1 billion years. That would have side-stepped issues like “hotter then the incoming sunlight” or “any mirror would melt” while still making the point that the earth would quickly become uninhabitable.

            I made my first post then noticed he had the emissivity factor in the equation so I made a second post that said:

            “One correction to the above. The Stefan Boltzmann law does not include the emissivity variable because of the difficulties of properly presenting that variable in a simple manner.”

            Not only is that the Stefan Boltzmann law without the emissivity factor but it would indeed be a blackbody calculation because blackbody emissivity is 1.0

            The emissivity factor should always be used in a real world problem because there is no such thing at least in our part of the universe of something being a perfect blackbody.

      Gordo never offers an basis from physics to explain how his atmosphere “dissipates” it’s thermal energy at night. The only mode of “dissipation” for the atmosphere is radiation heat transfer to deep space because there’s no convection or conduction possible in a vacuum. And, the outgoing thermal radiation also happens during daylight hours as well.

      Gordo needs to learn some physics, or quit trolling a science oriented group. That’s not likely, as he’s been so wrong for so long that he must have some ulterior motive for his moronic posts.

        As a result of convection, warm air rises, where the pressure drops and the gas increases in volume. The temperature must drop. Atmospheric layers above the globe increase the volume of air with increasing .

          Yes, the atmosphere is a mixture of gasses which expands when it is warmed and contracts as it cools. The cooling is the cause of the contraction. In your delusional physics, you have got the cause and effect backwards and are ignoring the process of cooling, i.e., the loss of energy to deep space. And, the fact is, that energy loss can only occur via thermal radiation heat transfer.

          To reiterate what E. Swanson said, these sentences muddle cause and effect. It ought read:

          During the day the atmosphere absorbs more energy than it emits, causing it to warm and therefore expand.
          During the night the atmosphere emits more energy than it absorbs, causing it to cool and therefore contract.

          It is always energy change -> temperature change -> volume change for earth’s atmosphere.

          The atmosphere absorbs energy from sunlight and from the warmer surface.
          The atmosphere emits energy to deep space. (And occasionally a bit the surface when there is a temperature inversion).

          Without the emission to space, there is no energy loss, there is no cooling, and there is no subsequent contraction at night.

        We all know that TOA radiation is in part how the earth cools. The question at hand isn’t that its how those free floating gases at TOA actually exact a rigid insulation like forcing all the way back down to the surface.

        We are already to hear the take on that that convinced you. So prove right now you aren’t a total boob.

          It’s not a ‘rigid’ forcing, but there is a simple-to-explain connection.
          * The CO2 at the TOA is what emits IR in the 15 um band to space.
          * The more CO2, the higher the altitude of the TOA.
          * The higher the TOA, the cooler it is.
          * The cooler it is, the less IR energy emitted to space in the 15 um band.
          * The less emitted @ 15 um, the more must be emitted at other wavelengths to achieve a steady-state.
          * the more emitted at other wavelengths, the warmer those surface would have to be.

          It’s all related to that most fundamental of principles, Conservation of Energy.

            I have no problem with that simple explanation of a steady state lapse rate.

            That’s the basis of insulated window physics.

            So the theory is that CO2 raises the height of the troposphere in order to insert additional layers is that correct?

          • Swenson says:

            Tim,

            There is no forcing, rigid or flexible. You are confusing fantasy with forcing.

            So –

            Anything at about 193 K radiates IR in the 15 um band. Doesnt matter if its on the surface or elsewhere.

            The height of the top of the atmosphere does not depend on CO2 in the atmosphere. Please dont tell me that TOA really means something else than Top Of Atmosphere! The alarmist use of redefinitions gets more bizarre each day.

            You are talking gibberish as usual. CO2, like anything else, radiates photons whose wavelengths are proportional to its temperature. No spectrometry or excitation involved here.

            Go away, learn some real science, and come back.

          • Tim Folkerts says:

            Swenson says: “Please don’t tell me that TOA really means something else than Top Of Atmosphere! ”

            Let me clarify. I should have said something more like “the CO2 that is detected when we look down from above the atmosphere”. So let me try again, with slightly different wording (but the same conclusion).

            * When looking down from outside the atmosphere, the 15 um IR that is observed comes from CO2.
            * The more CO2, the higher the altitude from which that 15 um IR comes.
            * The higher the altitude, the cooler that CO2 is.
            * The cooler it is, the less IR energy emitted to space in the 15 um band.
            * The less emitted @ 15 um, the more must be emitted at other wavelengths to achieve a steady-state.

            ******************************************

            “Anything at about 193 K radiates IR in the 15 um band. “

            This hints at some serious misconceptions. What you seem to be referring to is the fact that a blackbody at about 193 K radiates most strongly in the 15 um band. This is knows as “Wien’s Law”.

            But …
            1) Objects at other temperatures (both warmer and cooler) also radiate in this band. In fact, a blackbody at higher temperatures will radiate MORE in this band than a 193 K object.
            2) Non-black bodies radiate differently. For example, a ball of CO2 at any 193 K radiates a lot of IR near 15 um, as does a ball of ice. However, a ball of N2 at 193 K radiates essentially zero IR in the 15 um band, and a ball of polished silver also would radiate poorly near 15 um.

          You missed the point I made about Gordo’s delusional physics. Read back up the thread. He clearly doesn’t understand that the Earth emits thermal IR radiation to deep space.

          What convinced me you ask? How about reading several texts on atmospheric radiation heat transfer, and that after earning 2 degrees in ME. The atmosphere tends to be stratified in layers and I think models built using multiple layers should do a good job of representing reality. Then, one must understand that the GHG molecules radiate in all directions and emissions within a layer would tend to be absorbed again within that layer, so the net effect is that the IR in each layer at any GHG wavelength emits with the same intensity downward as upward. Compounded over many layers and the surface would be warmer than without those GHG’s.

          Sorry, I see no need to “prove” anything for you. You gotta figure it out for yourself.

          • bill hunter says:

            OK so lets assume thats correct. So in effect the ”convection adjustment” is a slowing of convection by slowing TOA cooling.

            We also have a more rapidly warming polar region (eventually for antarctica too) that reduces the movement of polar to equator convection loops.

            thus things like wind shear are also reduced. Now how do we end up with more hurricanes? Tornadoes? etc.

          • E. Swanson says:

            B Hunter, I think it’s more complicated than you suggest.

            Warming in the tropics appears as a measured increase in the pressure height of the tropopause, since there’s more convection as the radiation energy loss from the surface to to deep space is reduced. The vertical convection would be strengthened as the surface layers would become less dense due to the addition of more water vapor, which has a lower density than the N2+O2 mixture.

            I expect that the stronger vertical convection would result in stronger storm systems, both in the tropics and the mid-latitudes. Winter air mass movement from the tropics to the polar regions would also strengthen, leading to more intense weather at the boundaries between the warm and cold air masses. Remember that the tropics are in surplus, i.e., more solar energy arrives than thermal IR leaves above TOA and the poles are in deficit, the deficit being satisfied by tropic to pole energy movement via convective mass transfer. This may explain the data which shows greater warming during the polar winter than summer, even though the snow/sea-ice/ocean albedo feedback is strongest in summer.

            Or, as I’ve pointed out, this difference between polar seasonal temperature change, particularly that reported by the UAH data, may be incorrect due to the influence of the reported decline in melt season sea-ice area.

            But, hey, what do I know, I’m no professional PhD career guy.

            ==============================
            I haven’t suggested a mechanism. I was pointing out claimed effects of upper layers reducing radiation to space and the observed and warmist explained more rapid warming of the colder regions of the earth relative to the warmer ones. And both of those suggest less convection.

            And yes to correct for it there would need to be more convection at least at TOA, but not necessarily cross latitude.

            In fact while typing that the actual melting of the arctic allowing more heat from the oceans into the atmosphere via stripping of the ice insulation barrier between the atmosphere and the ocean, would suppress equatorial convection also perhaps accounting for the entire globe warming. Said to be a feedback but is it?

            But thats a distraction. Something to keep in mind.

            E. Swanson says: (parens my comments)
            ”Warming in the tropics appears as a measured increase in the pressure height of the tropopause, (wouldn’t that be expected in a warming world?).”

            ”since theres more convection as the radiation energy loss from the surface to to deep space is reduced. (my current understanding is that convection is restricted leading to surface warming and to correct convection will return to its original value)”

            ”The vertical convection would be strengthened as the surface layers would become less dense due to the addition of more water vapor, which has a lower density than the N2+O2 mixture.(isn’t this the hypothesized return of convection that was restricted by a lack of cooling at TOA?)”

            ”I expect that the stronger vertical convection would result in stronger storm systems, both in the tropics and the mid-latitudes. (stronger than the suppressed convection value? Yes! stronger than the original value, no!)”

            ”Winter air mass movement from the tropics to the polar regions would also strengthen, leading to more intense weather at the boundaries between the warm and cold air masses. (huh? storms come out of the arctic, not vice versa because the big convection loops deliver high level air above the poles that then cool and descend to the surface pushing surface air south. The restriction of convection at TOA is slowing that process down not speeding it up, you need another mechanism)”

            ”Remember that the tropics are in surplus, i.e., more solar energy arrives than thermal IR leaves above TOA and the poles are in deficit, the deficit being satisfied by tropic to pole energy movement via convective mass transfer. This may explain the data which shows greater warming during the polar winter than summer, even though the snow/sea-ice/ocean albedo feedback is strongest in summer. (this fact tells me that since emissivity equals absorp-tion per Kirschoff’s law that if the polar region is default a heat loser that when you lower the emissivity it becomes a bigger heat loser via heat loss being proportionally bigger than heat gain. This seems to be potentially part of an iris-like effect of warming)”

            ”Or, as Ive pointed out, this difference between polar seasonal temperature change, particularly that reported by the UAH data, may be incorrect due to the influence of the reported decline in melt season sea-ice area.

          • E. Swanson says:

            b hunter, there’s much in your post to which I disagree. To begin with, you mention”TOA”, but you appear to be thinking about the tropopause, which is a way below TOA, i.e., outside most of the atmosphere where satellites operate.

            Then you write: “.. my current understanding is that convection is restricted leading to surface warming..”, which I’ve not heard of. It should be obvious that increasing the water vapor content at the bottom of the atmosphere would result in stronger vertical convection. Perhaps you could provide a reference?

            Continuing, you wrote: “huh? storms come out of the arctic, not vice versa because the big convection loops deliver high level air above the poles that then cool and descend to the surface pushing surface air south.”. In the mid-latitudes, such as the US, the storms form along the boundaries between the polar flowing warm air masses and the returning cold air. The cold, dense air flows below the warmer air, forcing the warm air to rise resulting in precipitation as the moisture condenses. Both air masses exhibit rotation in a clockwise direction due to the Coriolis Effect and at the frontal boundaries, there’s a change in wind direction, which tends to spin up storms. In Winter, the storms which form in the North Pacific roll onto the west coast and progress across the US.

            Then you wrote: “this fact tells me that since emissivity equals absorp-tion per Kirschoff’s law that if the polar region is default a heat loser that when you lower the emissivity it becomes a bigger heat loser via heat loss being proportionally bigger than heat gain.” You are focusing only on surface emissions while ignoring the atmospheric emissions. And, the snow/ice albedo effect applies only to solar energy, not thermal IR emissions. Besides, over the Arctic Ocean in the summer melt season, there is frequent cloud cover and thus the out going emissions tend to originate from the clouds, not the surface.

            Regarding the UAH data over the Arctic, they are useful for short term weather forecasts, but may not provide an accurate picture of the longer term trends, in which is what we are most interested.

            Mental models are fun, but, as we all know, they aren’t worth the paper they are written on.

            All I am doing here is using the only reference so far supplied to me by Nate for evidence that convection didn’t override the forcing of new undescribed layers at the top of the troposphere.

            You are jumping ahead of the discussion Swanson to a surface forcing.

            It gets a bit confusing because I can acknowledge continued leakage of CO2 bandwidth to space on the shoulders of a single layer near TOA single layer model that additional CO2 could fill.

            The only thing I am issuing challenges for evidence is that the idea of multiple radiation exchanges in the atmosphere results in a greater forcing at the surface.

            You previously wrote: “And yes to correct for it there would need to be more convection at least at TOA, but not necessarily cross latitude.” Most of the vertical convection is in the troposphere and there’s little in the stratosphere above, which is the reason I mentioned TOA.

            But when it comes to explaining it its all mental models.

            And I don’t see how that relates to UAH temperature record. Reading temperatures with IR equipment is a well documented and correlated process. Not sure what the mental model part is.

            The MSU/AMSU instruments don’t measure IR “temperature”, like that from a hand held IR thermometer. They measure microwave intensity in a narrow bandwidth, which is the result of emission/absorp_tion from the ground to the instrument orbiting above TOA, then compare that measurement to that from a heated target at known temperature and a scan of deep space. The instruments scan side-to-side across the ground track, with the middle being downward at nadir and the end scan positions viewing near the “limb” of the Earth. Each scan position “sees” a different peak emission altitude, but all are weighted averages over a range of pressure altitudes. S&C take these measurements from each scan swath and combine them using a theoretical math model to create their MT, TP and LS data series. They then combine these three using another theoretical model to create the LT product which we all enjoy each month.

            All you are saying there Swanson is climate varies and people pretend to have mathematical models to explain it all. . . .except that those models don’t explain it. Perhaps you need a few lessons in the scientific method, control of experiments, statistics, and the validity of apriori assumptions such as is there really a GHE. Its easy to beg the question in an argument and its far too much easier to do it in a mathematical model than it is in a philosophical model, and that’s because philosophical models inspect all the various assumptions in a language everybody can understand. . . .whereas highly trained numerically focused determinists often fail to do.

            ===================

            Yes but in an atmosphere I think backradiation doesn’t matter.

            Backradiation in window technology is routinely ignored and test results show it doesn’t matter. If those tests are too inaccurate is a possibility but thats why I would like to see a bigger test that demonstrates that fact. It seems to me the null hypothesis should be no, backradiation does not matter.

            Intuitively I think it does matter in a vacuum but actually I would like to see that established via carefully measured testing in a vacuum environment. . . which may have already been done just that I haven’t seen the tests. Shouldn’t be a hard test to do getting good vacuums at sea level is a challenging job but perfect isn’t all that necessary.

            ===========================

            LMAO, Ol William Happer. Come on Swanson Happer is incredibly well qualified to talk about those matters. You are embarrassingly wrong in criticizing his use of IR. Here is the key definition:
            ”The infrared part of the electromagnetic spectrum covers the range from roughly 300 GHz to 400 THz (1 mm 750 nm). It can be divided into three parts: Far-infrared, from 300 GHz to 30 THz (1 mm 10 μm). The lower part of this range may also be called microwaves or terahertz waves.”

            Beyond that weirdo criticism, which actually is a big negative to your case; the UAH methodology is so superior from a sampling point of view to the surface record its almost a joke. From an accuracy point of view the surface record is constantly undergoing adjustments for non-heterogeneous sampling techniques – – -using not a whole lot more than a divining rod with the assumption that station managers are morons as a guide. I could go on and on about problems with assumptions about buckets, engine intakes (actually have worked on a few boats), XBTs, ARGO corrections, time of day, and probably a few more I have forgotten. I have years of sample design experience that is connected to the kind of industries I have worked in over the past 35 years as a consultant. Give me any sampling design and its like the doctor hit my knee reflex muscle and I have a list of items to look more closely at. This is the entire problem with proxies, especially in the area of bias which is endemic to everything political. Microwave scanning of the surface I am sure has a few flaws in coverage of spherical object but they are teensy weensy compared to surface temperature station coverage.

            Its actually ridiculous to consider anything but, IMO. But we are stuck with surface station data before 1980 and I love for archaic projects to continue to provide coverage for the sake of consistency even if I really can’t make a really good argument for why. I use satellite data regularly both professionally and recreationally. It is ridiculously superior to what I used when I first started with such data some 50 years ago.

            I suspect that if you personally had a real world application for the use of the data you would quickly grow to understand that.

            BTW, speaking of where you get your scientific information, you still havent given your reference to Nates source.

            I’ve worked with dynamic models on several occasions and found them very useful for, example, in satellite control systems design and railroad accident reconstruction. Other engineering applications for models, such as finite element models for load calculations, are common. AIUI, the models used for climate projections are similar to weather models, except that they must be run with longer time steps because of computational constraints. The climate models don’t “explain” anything, they just simulate things, given a set of assumptions.

            Nobody said they can’t be useful Swanson. Its just their use in trying to figure out how the greenhouse effect exacts a surface forcing to create a greenhouse effect isn’t like to succeed for at least two reasons, one of which might doom it to failure and the other all but certain to doom it to failure.

            There only use is to try to scare people. Dr. Lindzen knows it and has called them out on it. I know it because I have worked with sophisticated models where you can’t test outcomes or control variables. The models I have worked on are much more complicated, namely natural systems as opposed to engineered systems you have worked on.

            I glanced at your paper and it seems interesting. In fact part of your key finding was on the emissivity of water. I actually posed that question to Dr. Trenberth because he uses an emissivity 1.0 for the entire earth’s surface for his radiation budget. I understand that to be impossible having a few years seatime under by belt and have had to deal with water reflectivity constantly. Dr Trenbert provided me with some papers to support his position. After reading them they strongly supported a lower emissivity for water than 1.0 some significantly lower (I didn’t inquire about ice though). So rather amazed that Trenberth gave me supporting science contrary to what he was using I got back in touch with him and he merely said he didn’t believe the papers he gave me.
            Go figure!

      • bill hunter says:

        Let me take a shot at this.

        OK, this concept of work being employed from rising air is a bit of a misnomer. The reason is the total potential energy in the atmosphere never changes. And since it never changes there is zero work for convection to occur, instead convection is simply a process of diffusion that is always unstable (from the standpoint as a mean value) because of TOA cooling.

        And since no work has to occur this diffusion has no limits on how rapidly it will overturn air and via this overturning of air evaporation is accelerated creating an additional greenhouse effect over land and accounting for feedback.

        So really the only issue is the additional layering of CO2 within the troposphere having an effect. But thats where I become skeptical because the top of the troposphere seems defined by the upper limit of condensable water and with no work involved in potential energy the lapse rate won’t additionally destabilize.

        So the problem seems to be evidence that CO2 can cause water to rise into colder zones of the atmosphere and what does it look like up there in regards to saturation in the CO2 bands.

        It must not be too good or folks wouldn’t be talking about multi-layered gas insulation models, but it seems rather complicated how that kind of model would fit into a diffusing gas environment. All I know is such an environment in the study of insulating windows one can completely ignore radiation effects and simply calculate the gas diffusion effects.

        Please if you have comments stay on topic and avoid all the haranguing and heartburn the discussion might cause. I am just an amateur at this and would like to learn more.

          • bill hunter says:

            Well what I am saying isn’t inconsistent. If the gas laws are correct and indeed they are for ideal gases. And total potential energy is locked to the mass of the atmosphere, where does the energy for the work come from? I am an amateur at this. I just like to hear logical explanations. Not one that it must come from somewhere.

        That’s a tough one. Obviously Schmidt and Mann are dumber than Pierrehumbert because they run realclimate and have installed him as their climate science authority. Schmidt also used to be a subordinate to Hansen and Hansen taught him all he knows. Not sure how Trenberth fits into things but after his energy budget sci-fi and accepting Phil Jones of Had-crut as his Coordinating Lead Author partner at IPCC reviews, he’s questionable.

        Hansen, however, was a disciple of Carl Sagan, an absolute fool of a man who talked a bit like Elmer Fudd. That wouldn’t be bad in itself but he looked like Elmer and thought like him. Hansen, a physicist, spent much of his career following Sagan in astronomy, before dabbling in climate modelling.

        • Ramona Rivelino says:

          • ClintR says:

            Unfortunately you can’t “see”, Snape/Doris/Ramona. You’re “blind”. Your submission to a false religion has made you that way. You can’t see reality.

            A blackbody surface absorbing 960 Watts/m^2 could only achieve a maximum temperature of 391K. That’s it. For your “high priest” to claim otherwise indicates he is either incompetent or dishonest, or both.

            For you to continue to swallow such nonsense, while blaming others, makes you an idiot.

          • Tim Folkerts says:

            “A blackbody surface absorbing 960 Watts/m^2 could only achieve a maximum temperature of 391K. ”

            Clint, you have this all backwards! The article claims a perfect “silverbody” which emits nothing, not a blackbody, which emits perfectly. Your appeal to blackbodies shows you missed the point completely.

            You did get the calculation correct for a blackbody, with emissivity = 1. But what objects objects with about other emissivities that absorb 960 W/m^2?

            1.0 –> 361 K
            0.95 –> 365 K
            0.80 –> 381 K
            0.50 –> 429 K
            0.20 –> 539 K
            0.05 –> 762 K
            0.01 –> 1141 K

            There is, in fact, no theoretical maximum temperature for an object absorbing 960 W/m^2. The lower the emissivity of the surface, the hotter it could be. Its easy to get materials with emissivity = 0.05, so it would be easy to get the temperatures over 700K. In the theoretical limit of emissivity =0, the temperature goes to infinity!

          • ClintR says:

            Tim, upthread you were rambling in an effort to defend the nonsense. Now you are being either incompetent, dishonest, or both.

            The nonsense was CLEARLY about Earth, not some “silver body”. Here’s the text:

            “In a single second, Earth absorbs 1.22 10^17 joules of energy from the Sun. Distributed uniformly over the mass of the planet, the absorbed energy would raise Earths temperature to nearly 800 000 K after a billion years, if Earth had no way of getting rid of it.”

            Why are you discrediting yourself by trying to save this absolute crap from the toilet?

            And you don’t understand “emissivity”.

          • Swenson says:

            Tim,

            So how hot could an object get absorbing 300 W/m2?

            The 300 W/m2 is being emitted by ice.

          • Tim Folkerts says:

            Clint,

            Those two sentences are clearly NOT about earth. The hint is the two words “would” and “if”. The sentences are about some object with the same mass and same energy input as earth, but this object is different in that it is hypothesized not to be able to radiate away energy.

            To prevent thermal radiation from leaving, the object must have emissivity equal to zero. This means the object must be perfectly reflective (or perfectly transparent). A perfectly reflective object is perfectly shiny = perfectly silver.

            **************************

            Clearly those sentence were designed as a “hook” to catch attention. The article is a general interest article in a physics magazine, not a scholarly research paper in a journal. As such, it can be written in a little more flamboyant style.

            Those sentences are not a step within a developing argument. Those couple sentences could be deleted without affecting anything in the rest of the article. Those sentences are not the style I would have chosen, but they are not intrinsically false. (They are certainly able to mislead, especially with people who want to be misled.)

          • Tim Folkerts says:

            So how hot could an object get absorbing 300 W/m2?

            The 300 W/m2 is being emitted by ice.”

            Ah! This old nugget. This is a different situation than we have been discussing, in that now we are assuming the only input is uniform thermal radiation (Rather than a generic 300 W from any sort of source — say an electric heater embedded in the object).

            Given walls of ice at 273 K and emissivity = 0.95 emitting 300 W/m^2 as the only energy arriving at the object, the object could only get to the exact same 273 K.

          • ClintR says:

            TimF provides a perfect example of his devotion to the cult.

            Here’s the text, with bold my emphasis:

            “In a single second, Earth absorbs 1.22 10^17 joules of energy from the Sun. Distributed uniformly over the mass of the planet, the absorbed energy would raise Earth’s temperature to nearly 800 000 K after a billion years, if Earth had no way of getting rid of it.”

            The example is clearly talking about Earth.

            Here’s how TimF tries to deny reality:

            “Those two sentences are clearly NOT about earth. The hint is the two words “would” and “if”. The sentences are about some object with the same mass and same energy input as earth, but this object is different in that it is hypothesized not to be able to radiate away energy.”

            See how they do it? They just make up stuff to support their nonsense. They have no problem rejecting “truth” and “reality”. They much prefer perversion and corruption.

          • Swenson says:

            Tim,

            Ah, the magic embedded electric heater! At least you admit that an object receiving LWIR radiation from ice cannot become hotter than the source of the radiation.

            So how hot would an object get receiving 960 W/m2 from the sun? Assume the Suns temperature is 5800 K.

            You and Pierrehumbert are as thick as each other.

          • Swenson says:

            RR,

            How hot can something get if the heat source is 5800 K.

            The maximum is 5800 K, donkey! Not 800,000 K.

          • Svante says:

            If you ignore Pierrehumbert’s premise.

          • ClintR says:

            Silly Svante. your “priest’s” premise makes it even worse. He uses 960 W/m^2. That means the maximum temperature would only be 361K.

          • Tim Folkerts says:

            “At least you admit that an object receiving LWIR radiation from ice cannot become hotter than the source of the radiation.”

            I think everyone everywhere (who has even a basic understanding of the physics involved) ‘admits’ that an object whose only source of energy is radiation from an object at temperature T cannot get warmer than T.

            If you can find anyone who actually claims that radiation from 273 K ice (without any other source of energy) can make an object warmer than 273 K, I would be fascinated to see it. Otherwise, give up on this strawman already!

          • Tim Folkerts says:

            “They just make up stuff to support their nonsense. ”
            I didn’t “make up” the words “would” or “if”.

            There are two choices.
            1) The object being described IS the earth, and the earth cannot radiate away thermal energy.
            2) The object being described IS NOT the earth, but is a similar object that cannot radiate away thermal energy.

            There is really no other choice.

            ===================================

            this is brings up another troublesome question for me.

            The sun is 5800k. The radiation arriving from the sun is capable of warming something like the earth’s shape to ~278.5k based upon 341 watts being received.

            Yet the thermosphere is estimated to be a couple thousand k. reading a bit on it, it seems that this temperature isn’t actually measured but in some way deduced. Suggesting that via certain frequencies and the inability of monatomic oxygen and nitrogen can only absorb high frequencies and thus only emit high frequencies the atoms up there get hotter than what the earth is capable of by a long shot. Perhaps only limited to the 5800k.

            but now we have a different radiation theory based upon the energy of vibrating light frequency waves which raises the question of how CO2 with its low frequency band could produce a greenhouse effect.

            While this might not apply to the method described that slows convection by warming the upper atmosphere it does begin to debunk a lot of nonsense about backradiation.

            Tim Folkerts crickets on my question suggests he sees may possible ways that the GHE could work and isn’t sure which one it is.

            thats not exactly the kind of comforting professional advice about my investment strategy. Its about that point that uncertainty begins to demand a whole lot of additional potential rewards – pushing that return on investment well up into the double figures.

            It has that sound of investment advice that sounds like advice to lay on the couch more because you might break a leg at work. . . .or even possibly. . . .gasp. . . .die!

            And all this advice has actually largely arisen via a guy that thinks coal miners are better off without a job. Of course Joe Biden doesn’t see it that way. After all they could all become programmers.

            Of course nobody wants to talk about any of those details and thus. . . .crickets!

            Hotter deeper

            Hotter further out

            the thermosphere is very thin and is heated by UV. The thermosphere absorbs almost all the extreme ultraviolet that it receives.

            The extreme ultraviolet comes from the corona, not the surface.

            Is it a different theory, or the same one, that matter absorbs and emits radiation based on the energy levels available in the individual atoms and molecules?

        By the rules of the scientific community, peer-reviewed literature from establishment journals represents the frontier of knowledge. It is the foundation of knowledge on which your work should build; other research literature (technical reports, conference proceedings, web sites, submitted papers) is called “gray”. You may find it useful and it may give you advance notice of new work, but it is not considered “knowledge.”

        How to read papers

        1. Begin with the abstract (of course). Is it useful? If no, you don’t need to read further. If yes, you do.

        2. Read the intro. A good intro is designed to motivate the paper in the context of previous literature. It often gives you a useful perspective on how others look at the research problem.

        3. Read the conclusions. They expand on the abstract and often present broader perspectives that may be useful to your work.

        4. Read the sections that are of specific interest to you or for which you have specific responsibility. You may be most interested in the model description, a data table, a piece of analysis…you shouldn’t feel obligated to read the whole paper. If you’ve read the abstract and conclusions you have done your duty as far as staying on top of the literature. The rest is to serve your practical needs.

        5. If there are fundamental things that you don’t understand in the paper, don’t be complacent. Go to the textbooks and learn about them. There is no excuse for ignorance.

The “if it could not radiate” is merely a lead-in showing what would happen if the laws of physics WERE violated in a specific way.
