Climate Audit: IPCC AR6 is Worse than you Thought

Guest essay by Eric Worrall

Steve McIntyre is at it again, dissecting questionable climate science. If you thought Michael Mann’s original climate hockeystick was interesting, with its intriguing apparent use of upside down proxies and apparent data deletions, check out McIntyre’s deep dive into the product of an entire team of climate scientists who think like Mann.

The IPCC AR6 Hockeystick

Although climate scientists keep telling that defects in their “hockey stick” proxy reconstructions don’t matter – that it doesn’t matter whether they use data upside down, that it doesn’t matter if they cherry pick individual series depending on whether they go up in the 20th century, that it doesn’t matter if they discard series that don’t go the “right” way (“hide the decline”), that it doesn’t matter if they used contaminated data or stripbark bristlecones, that such errors don’t matter because the hockey stick itself doesn’t matter – the IPCC remains addicted to hockey sticks: lo and behold, Figure 1a of its newly minted Summary for Policy-makers contains what else – a hockey stick diagram. If you thought Michael Mann’s hockey stick was bad, imagine a woke hockey stick by woke climate scientists. As the climate scientists say, it’s even worse that we thought.

It’s hard to know where to begin. 

The idea/definition of a temperature “proxy” is that it has some sort of linear or near-linear relationship to temperature with errors being white noise or low-order red noise. In other words, if you look at a panel of actual temperature “proxies”, you would expect to see series that look pretty similar and consistent

But that’s not what you see with the data used by the IPCC. You’d never know this from the IPCC report or even from the cited articles, since authors of these one- and two-millennium temperature reconstructions scrupulously avoid plotting any of the underlying data. It’s hard for readers unfamiliar with the topic to fully appreciate the extreme inconsistency of underlying “proxy” data, given the faux precision of the IPCC diagram.

Plenty more where that came from, well worth a few minutes read.

One of the most fascinating finds McIntyre interprets as a new attempt to “hide the decline”, though he has grave concerns about the entire reconstruction which was snipped. Read his full article to delve into the details of this latest episode of alarmist data torture.

What can I say, as long as we keep paying them, they will keep on producing.

… the faux precision of the IPCC diagram.

It’s the same with radiation budgets, carbon budgets, and temperatures. The public and policy makers are presented with data that is implausibly accurate/precise. Of course error bars aren’t presented on ‘their’ pretty diagrams.

The accuracy of a number is indicated by the number of significant digits. If you give a number as 147, that’s three significant digits, 150 is two significant digits and 147.0 is four. So, presenting a number with +/- 10% error bars as 147 is lying.

The graphical designers routinely (always) present imprecise data with a number of significant digits that imply accuracy that is not supported by research findings. The fact that those diagrams are published and not repudiated by the scientists who produced the underlying data means those scientists are OK with lying.

I am well aware that news reporters routinely misquote experts and it’s almost impossible to get a correction. Let’s just say, that when it comes to climate data presented to the public and policy makers, lying is a feature not a bug. ie. dishonesty is built in to the system.

Actually, the number of significant digits tells you the precision of a measurement. In other words, how well you can repeatedly obtain the same measurement. Accuracy is determined by how well an instrument’s measurements compare to an accepted standard. You may have a precise measurement but it may not be very accurate. To have a good measurement, it must first be precise as possible which then can determine how accurate it truly is.

In my last 5 years or so working as an R&D engineer at a major national laboratory, I used to tell colleagues in my times of cynicism, which was most of the time, “the only science that matters anymore is political science” and “integrity is a character flaw.” Sadly, in every single case, I got nods of agreement.

Over my many decades as a solar thermal R&D engineer, I was the focus of over a dozen press releases. In absolutely every single case, the reporters managed to twist my input to the point that it barely represented what I was doing, at best, or to the point that even I didn’t understand the article.

For the record, solar energy engineering is really really hard! I specialized in the thermochemical production of solar fuels and collaborated with nuclear engineers interested in similar approaches. Given the challenges for solar or nuclear fuels production, i.e. hydrogen, there is no one more grateful for the fracking revolution than me.

I have had the same experience when being interviewed on the topic of gun control. I don’t know whether reporters are intellectually incapable of remembering a few words, or if they purposely twist the meaning to conform to their belief set. Most of the time it didn’t even sound like the way I talk.

Isn’t that like saying that since one climate model, out of more than a hundred, produced semi-accurate predictions that that means that climate model predictions are accurate.

Just because a stopped clock is absolutely correct twice a day, you can’t claim that it is accurate.

Peak Oil, a Specimen Case of Apocalypic Thinking  (LINK) Prophets of doom held that looming shortages of oil would plunge us back into a Paleolithic standard of living. What’s interesting is why the prophecies were accepted—and whether we’ve learned anything at all from it

===

Peak oil alarums have been ongoing for over 100 years. We will not run out of oil, it will be the economics that dictate whether we can use it anymore profitably.

There will be no more off topic diversions for your pet topic, GO HERE to talk about peak oil as it IS part of the topic, I will start snipping out your off topic peak oil since you are diverting many here to get off topic following your false trail.

From the ever unreliable New Scientist:

…a 1971 paper by Stephen Schneider, then a climate researcher at NASA’s Goddard Space Flight Center in Maryland, US. Schneider’s paper suggested that the cooling effect of dirty air could outweigh the warming effect of carbon dioxide, potentially leading to an ice age if aerosol pollution quadrupled.

This scenario was seen as plausible by many other scientists, as at the time the planet had been cooling (see Global temperatures fell between 1940 and 1980). Furthermore, it had also become clear that the interglacial period we are in was lasting an unusually long time (see Record ice core gives fair forecast).

https://www.newscientist.com/article/dn11643-climate-myths-they-predicted-global-cooling-in-the-1970s/#ixzz73JvYb5BJ

Schneider featured in the documentary “In Search of the Coming Ice Age”, presented by Leonard Nimoy, in which he told us we were going to freeze to death. The documentary has been largely ‘disappeared’ by YouCensor etc

Then he popped up in the 90s saying….

“On one hand, as scientists we are ethically bound to the scientific method, in effect promising to tell the truth, the whole truth, and nothing but—which means that we must include all the doubts, the caveats, the ifs, ands, and buts. On the other hand, we are not just scientists but human beings as well. And like most people we’d like to see the world a better place, which in this context translates into our working to reduce the risk of potentially disastrous climatic change. To do that we need to get some broad-based support, to capture the public’s imagination. That, of course, entails getting loads of media coverage. So we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have. This ‘double ethical bind’ we frequently find ourselves in cannot be solved by any formula. Each of us has to decide what is the right balance between being effective and being honest.” – —Dr. Stephen Schneider, former IPCC Coordinating Lead Author, APS Online, Aug./Sep. 1996 

Who takes him seriously?

As I pointed out to you a few days ago, that is a selective quotation. Schneider actually wrote.

This ‘double ethical bind’ we frequently find ourselves in cannot be solved by any formula. Each of us has to decide what is the right balance between being effective and being honest. I hope that means being both.

Carefully removing the last sentence is highly dishonest in my view, as it shifts the whole meaning of the quotation. That you willingly repeat the dishonesty makes it hard to take you seriously.

Here is Schneider, with a little context:

Let’s turn to that other “oxymoron” problem: the role of the scientist as popularizer. In the real world, we want to make a lasting impression and ensure that our ideas are heard and our suggestions are followed, yet none of us is granted unlimited time to explain the nuances of complex issues. We are forced to be selective in our disclosure of facts, or we risk being ignored. However, intentionally distorting the likelihoods of certain outcomes is just dishonest. Balancing the need to be effective in sound-bite situations with the responsibility to be “honest” (i.e., fully disclosing complexities) is what I call the “double ethical bind.””

Reply to  fretslider
August 12, 2021 4:31 am

You also selectively quoted the NS piece

However, Schneider soon realised he had overestimated the cooling effect of aerosol pollution and underestimated the effect of CO2, meaning warming was more likely than cooling in the long run. In his review of a 1977 book called The Weather Conspiracy: The Coming of the New Ice Age, Schneider stated: “We just don’t know…at this stage whether we are in for warming or cooling – or when.” […]

The calls for action to prevent further human-induced global warming, by contrast, are based on an enormous body of research by thousands of scientists over more than a century that has been subjected to intense – and sometimes ferocious – scrutiny.

“When facts change, I change my mind,” – John Maynard Keynes.

A good scientist presents the facts honestly and effectively, even if new evidence falsifies an earlier hypothesis, as happened with aerosol cooling.

Fifty years ago he wrote a paper on aerosols that made a conditional prediction that a fourfold increase in such would lead to a 3.5C decrease in global temperatures. Completely plausible given the state of knowledge a half-century ago. But since then aerosols declined under various clean air legislation and the enhanced greenhouse effect – also discussed in the same paper – became the dominant climate driver.

In other words, the conditionas attached to the prediction never came to pass, instead the facts changed and Schneider changed his mind. To do otherwise would have been dishonest.

You still can’t quite seem to hit that nail on the head, try as you will. “Climate change” is a logical fallacy. Global warming is a condition of natural variation (as is cooling). There’s no evidence of human causation. Schneider was 100% a political animal, with a conditional understanding of climate. You’re an apologist for science illiteracy and need to start educating yourself with facts soon before your brain locks at permanent dysfunction.

To quote the wonderful New Zealand poet, ARD Fairbairn:
‘What a tangled web we weave
When first we practise to deceive.
And when the art we have perfected,

Definitely there is context to be considered, however, perusing the climategate emails, one gets the impression that Schneider would readily sacrifice honesty to make some point consistent with his beliefs. That’s consistent with fretslider’s sentiment.

Sadly, he died over 11 years ago, so any further explanation of his thinking is at least partially speculation on our part. There is prescience in his statement that none of us is granted unlimited time to explain complex issues.

In his later years, he suffered from cancer and ultimately succumbed to a heart attack during international travel to attend a global warming conference.

Being honest matters, being effective does not. If the data has been manipulated, if you mask opinion as fact or dishonestly represent guesses as honest data then you are not a scientist, your opinion and work is worthless and your effectiveness is zero as everything you have done is undermined by the lies and dishonesty. There is no ‘double ethical bind’ – promote honest scientific research or get the hell out and become a used car salesman.

Good point, BUT…

… the problem is the meaning of “being honest”. If we don’t know, being honest is to say “We don’t know”, NOT to say whatever is convenient, useful, appropriate, helpful, favouring, etc., for instance, that global warming is a problem, when we don’t know if it is or not, and if it is, how big it is.

“Being honest”: is it an absolute or a limited concept? The old joke applies, the advice of the father to his son: “My son, live your life with honesty, if you can. If you cannot, live your life!”

So, the question is: can you be scientificaly honest while asserting imminent catastrophes? Are you living your scientific life with honesty or are you simply living your scientific life?

But it didn’t used to be this way. There was a time when scientists were hired by universities to teach and do research.

The moment researchers got rich grants, they also got bosses deeply interested in those earnings whose own pay was dependent on their subordinates getting rich grants.
They also got teams of administrators and accountants to track the grant monies and manage the spending.

All of whom put pressure on researchers to get more grants.
Published research by researchers aid in them getting grants, which increased the pressure on researchers to publish and get grants.

The IPCC cites Kaufman et al. 2020 a and b for that graph (AR6 WG1 section 2.3.1.1.2). Bristlecone pines are not used as a proxy. The proxy types used are chironomid, pollen, biophysical, isotope, Mg/Ca, alkenone, biomarker, and microfossil. It does not look very scary to me, but that is subjective so to each his own.

I may be incorrect here. SPM.1 utilizes Kaufman et al. 2020b which incorporates PAGES 2K for the most recent 2000 years. That database does contain tree ring proxies. I’m not sure about Bristlecone pines though. I would assume they are used within the most recent 2000 year period unless someone knows specifically if PAGES 2K excludes them.

Ah, those Bristlecones again. One of McIntyres greatest hits, so good he brings them up and the fact that the NAS panel ‘advised against their use’ every chance he gets.

But wait, panel chairman Gerald North clarified in a followup interview that the problems with stripbark samples were confined to the last 150 years – a period for which we have a wealth of other proxies. And what’s this? Is it possible the problems with stripbarks are not even real?

” (i) The unique 20th-century increase in ring width is specific to the upper forest border and is not associated with a particular elevation. The link to upper treeline rather than to a specific elevation is not consistent with the WUE hypothesis of indirect fertilization by CO2 or fertilization by nitrogen deposition. (ii) The strong modern trend in growth observed at the upper forest border is not the product of any preprocessing or standardization of the data—there was none. (iii) The modern trend is not related to the difference between strip-bark and whole-bark growth forms.”

Recent unprecedented tree-ring growth in bristlecone pine at the highest elevations and possible causes.

Well, the source of that conclusion is Gerald North, head of the panel that McIntyre so frequently cites on this.

The strip-bark forms in the bristlecones do seem to be influenced by the recent rise in CO2 and are therefore not suitable for use in the reconstructions over the last 150 years. One reason we place much more reliance on our conclusions about the last 400 years is that we have several other proxies besides tree rings in this period.”

This is the ultimate cop-out. Relatively accurate thermometers were not invented till 1714, and weren’t very accurate for the first 100 years due to solubility of the glass of the day in mercury.
So he is basically saying that the reconstructions are “good” prior to scientists having measuring devices. But you can’t calibrate the proxies against the last couple of hundred years “Cuz antropo-effects”. Completely self validating tripe.

If they aren’t suitable over one time period, and especially if you don’t know why, then they aren’t useful over any other period.

Steve McIntyre is at it again, dissecting questionable climate science. If you thought Michael Mann’s original climate hockeystick was interesting, with its intriguing apparent use of upside down proxies,

You are getting your myths in a muddle, the ‘upside down’ Tiljander proxy was not included in the original 1998/99 MBH studies. 

It was indeed used in Mann et al 2008. My take on it is that the signal was probably contaminated in modern times which may have reversed the sign during the calibration period compared to earlier years. But you don’t get to change your method on a per-series basis, so the choice was to include proxy as it was or exclude it. In fact they did both, they noted potential problems with the data and did the reconstruction with and without Tiljander, and some other series with potential quality issues. Impact on conclusions? Negligible. 

we also examined whether or not potential problems noted for several records might compromise the reconstructions. These records include the four Tijander et al. (12) series used for which the original authors note that human effects over the past few centuries unrelated to climate might impact records (the original paper states ‘‘Natural variability in the sediment record was disrupted by increased human impact in the catchment area at A.D. 1720.’’ and later, ‘‘In the case of Lake Korttajarvi it is a demanding task to calibrate the physical varve data we have collected against meteorological data, because human impacts have distorted the natural signal to varying extents’’).

In addition there are three other records in our database with potential data quality problems, as noted in the database notes: 

Benson et al. (13) (Mono Lake): ‘‘Data after 1940 no good—water exported to CA;’’ Isdale (14) (fluorescence): ‘‘anthropogenic influence after 1870;’’ and McCulloch (15) (Ba/Ca):
‘‘anthropogenic influence after 1870’’.

We therefore performed additional analyses as in Fig. S7, but instead compaired the reconstructions both with and without the above seven potentially problematic series, as shown in Fig. S8.

John, if you have a source for those quotes I’ll consider them. As I recall, and after refreshing my memory at Climate Audit, the problems with Tiljander may have been noted in the SI, but for the study the Tiljander series were used upside down in their entirety:
https://climateaudit.org/2009/10/14/upside-side-down-mann-and-the-peerreviewedliterature/

“The SI to Mann et al 2008 conceded that there were problems with the recent portion of the Tiljander proxies (without mentioning that they were using them upside down from the interpretation of Tiljander and Finnish paleolimnologists), but argued that they could still “get ” a Stick without the Tiljander sediments. However, as I observed at the time, this case required the Graybill bristlecone chronology (where they failed to mention or cite Ababneh’s inability to replicate Graybill’s Sheep Mt results, even though Malcolm Hughes, a member of Ababneh’s thesis panel was a coauthor of Mann et al 2008). Thus their “robustness” analysis used either upside down Tiljander sediments or Graybill bristlecones.”

As for the results being negligible, maybe not:
https://climateaudit.org/2009/02/26/upside-down-tiljander-in-japan/

“At this point, there are also issues of whether the SI actually shows that “none of their central conclusions” relied on their use. One of their central conclusions was that they could “get” a stick without dendro proxies – but their non-dendro recon used upside-down Tiljander. Their SI showed that they could “get” a stick without Tiljander but, as far as I can tell, the non-Tiljander comparandum used dendro series and, in particular, relied heavily on a Graybill bristlecone. It’s a large job analyzing the impact of this sort of thing. At the time, I didn’t have a working version of Mannian EIV; one of the reasons for working through Steig RegEM in such detail was to get a handle on Mannian RegEM and I may well re-visit this matter in the near future.”

These newer “reconstructions” appear to deviated from recorded history & archeology. The graphs are probably more to do with programming than reliable facts. There are 100’s of samples around the world similar to the Roman & medieval warming periods so not just a small local area. There’s many studies of proxies to give 1000’s of data points around the world but they rely on relative changes not absolute so they’re hard to merge. Further back tends to average values over longer periods so they tend to hide actual variability.

The Norse were raising cattle and growing barley in Southern Greenland circa 1000, which would strongly imply that it was considerably warmer than the present. Old treelines in various other places also have the same indication.
Mann et al apparently thought the LIA was inconvenient for the “CO2 is the thermostat” model, so eliminating it served his purpose.

Hey Eric, has anyone done any work on estimating the real uncertainties of these reconstructions? It seems that yet again they’ve assumed each proxy has random errors and they can just use the standard deviation or something to get their fake 95% confidence interval.

August 12, 2021 6:19 am

The “hockey stick” curve obscures Earth’s CO2 history.  Dinosaurs that roamed the Earth 250 million years ago knew a world with five times more carbon dioxide than is present on Earth today.

Summary: Feeding the world’s hungry ranks among the greatest difficulties humankind has experienced. Greenhouse growers in America and China, are enhancing plant growth as they intentionally increase CO2 levels to around 1,500 ppm, or 4 times today’s CO2 levels to boost plant yield by 25 to 65 percent for the plants they are growing, to produce greater amounts of vegetables and crops for humanity.

There are two sources of uncertainty, the first as you mention is accuracy in the placement, maintenance and reading of actual thermometers.

The whole premise of the 95% confidence level of the proxies used before the invention of the mercury thermometer in 1714 is LUDICROUS…The graph shows it to be 0.5 C wide, when it is actually more likely 2 C wide. Take some pond pollen samples and tree trunk cores and have them analyzed by a local university for the last few decades. Results will more likely match rainfall records rather than temperature.
But if you make that graph gray zone 2C wide, our 1C over the last century doesn’t look very scary for climate caterwaulers.

Thanks. I appreciate that. Really. My biggest fear though is posting something incorrect and no one says anything and it sits there for all of eternity. Either way posting and engaging in debates on here is really good way to learn about the climate. Mistakes are par for the course.

Whatever happened to the Medieval Warm Period (circa AD 900-1100) in the AR6 hockey stick graph? Most of the more honest proxy reconstructions show the MWP as warmer than the present.

If the AR6 writers think it’s so much warmer now than during the MWP, why don’t they go live in Greenland to escape the heat, like the Vikings did? They could get beachfront property there for much cheaper than in Florida, which (according to them) will soon be underwater. Somehow, the real estate market, including former president Obama (who said he would stop the seas from rising), is ignoring their warnings!

The MWP isn’t especially discernable in SPM.1 because that is showing a global temperature reconstruction which includes the whole Earth; not just the land areas on the periphery of the North Atlantic. To analyze the MWP proper you need to switch back over to North Atlantic or with slightly less discernability NH reconstructions.

Funny, how a warm period that shows up in proxies from all over the planet, becomes a N. Atlantic only phenomena when that is what the warmunists need.

They needed to get rid of the MWP, and they worked hard until they did.

It was always a North Atlantic phenomenon. Hubert Lamb who pioneered the research and even coined the term (or more precisely the variation Medieval Warm Epoch) in 1965 said so. You can read about what Lamb actually said here. We now know that it was likely the result of the ebb and flow of the AMOC.

The MWP proper does not show up in proxies from all over the world. Different sites certainty have periods of higher temperatures, but they were not synchronous. When one region is cooling another is warming and vice versa. This is the effect of ENSO, SOI, ocean currents, and other cyclic processes in the climate system moving the heat around. When you composite the temperature into a global reconstruction like what Marcott et al. 2013, Kaufman et al. 2020, and others did you see that the global temperature does not exhibit the same bump during the MWP proper period as it evident in more localized reconstructions like for the NH or more specifically the North Atlantic region.The LIA is a bit different though. That was a global event though the magnitude was higher in the NH and especially the North Atlantic region. That’s why it shows up in the SPM.1 figure.

The resolution of the proxies is not high enough to catch those things as century spanning periods as they do with the MWP.

Therefore, this argument is not valid for the interpretation of MWP signals from the southern hemisphere as only local isolated phenomena.

You just have to ask the people who left the PAGES2K consortium after 2013.

Here’s a comparison of their recent temperature reconstruction of NH to the PAGES2K 2019 paper:

Obviously, they come to very different results.

If I have to believe somebody’s honesty than it is people who abandon their very good chance to keep publishing in high impact journals cause they are more about the data than their career.

The 1992 United Nations Framework Convention on Climate Change committed the nations of the earth to reducing CO2.

Here we are 29 years later and emissions have never been higher.

Climate Science in action. Their prescription hasnt worked in 29 years. So now it is code red and the solution proposed is to double up the medicine.

To fix what ails us, the very brightest climate scientists tell us the solution is to take even more of the medicine that hasnt worked for 29 years.

“as long as we keep paying them, they will keep on producing.”

Eric – it isn’t possible to stop their funding. But what about alternative funding? It would be interesting to crowd source funding for qualified scientists to start from scratch and do it properly.

August 12, 2021 9:55 am

The IPCC is a One Trick Pony. They know only one song. Can see only one solution. Their medicine bag contains 100 identical bottles of asprins and nothing more.

Emissions are going to keep rising. 29 years of failed international agreements confirm this. The solution is how to best take advantage. When life gives you Lemons learn to make Lemonade.

Years ago during the first Arab oil embargo the notion of “Peak Oil” was all the rage.

What quickly became apparent is that peak oil only affects cheap oil. Expensive oil is never in short supply for long.

I basically agree with you. However, it is the cheapness that provides the economic ability to improve the standard of living. Expensive energy doesn’t offer that ability.

Where is the Medieval Warm Period around A.D. 1000 in that graph?
Also, the error bars are laughable.

The bump in temperature around the North Atlantic isn’t discernable in the graph because that is a graph of the global temperature. To see the MWP you need to switch back to a graph focused on the North Atlantic or to a lesser degree the NH.

I’m just overjoyed to see Steve McIntyre writing about these things again.
I’ll enjoy reading his works at my leisure.

As Steve McIntyre writes

“””Precisely why local Cape Ghir (offshore Morocco) temperatures were going down is somewhat of a quandary. Rather than figuring out this quandary, Neukom and the woke just turn the series upside down, following the example of Upside Down Mann by orienting the series according to its correlation with target instrumental temperature, even in their “CPS” reconstruction – a technique that is normally resistant to opportunistic flipping of proxies to enhance HS-ness of a final reconstruction.”””

some methods flip data and uses downtrending data to reinforce a warming trend.
I keep wondering at what stage a scientific unethical behavior like this becomes criminal.
And what could be a likely procedure to stop it in a US court?

The ubiquitous K-T atmospheric heat budget shows 63 W/m^2 LWIR upwelling from the surface.
This value appears TWICE!
Once sourced from the net, net solar energy 161 that arrived from the sun. Since it is not shown it must have slipped behind the sofa.
Second as part of the theoretical, “what if?” calculation for a BB at the surface temperature of 16 C used to calculate emissivity, i.e. 63/396=0.16.
When the music stops the solar 66 has chair in which to sit.
The calc’d 66 does not.
The greenhouse effect is a fifth grade math error.

Nick, this has been gone over by a lot of people and is not easy.
Nonetheless the figures do sort of balance and not in the way you are looking at it?
absorbed at Earth’s surface 161 from sun
Absorbed in earths atmosphere and clouds 78.
Total in 239.
Loss by latent heat and thermals 97. to the atmosphere
Now contains 175 W.

Now 161- 97 leaves 63 W at the surface having to make its way back to space by eventual radiation
But the temperature of the earth surface is 15C which BY SB means it has to be 396 W of energy to be radiated.
This demands an estimated back radiation of some 333 W from the GHG. to warm it, not to radiate to space!!!
Of the 63 left to go back to space 40 goes out direct IR.
The last 23 W goes into the atmosphere to make its way back out from the surface via both clouds and atmosphere.
Altogether 198 W in the atmosphere [plus 40 direct out makes the outgoing 238]
This is not made out clearly in the diagram
Which shows 30 of the 198/199 going out from the clouds and the other 169 going from the atmosphere.
There is 396 surface radiation from the energy in the system leaving the earths system only 63 watts of this is going to go back into space.
There is no extra 333 W of energy created from nothing.
The surface has to reach this temperature to radiate enough of its energy to the higher CO2 and H2O which by the way are radiating the 239 W from molecules at much lower temperatures than a 239 W earth surface would reach as it is much higher up and spread out it is much colder.

The GHG effect is real.
The assumption that warming atmospheres mean more heat retention is wrong.
No 0.9 retention.

The heat comes in and goes out CO2/H2O determine which layer is hot.

I haven’t read the report yet (I did read much of the previous ones) but it sure sounds like the IPCC has decided to completely abandon reality. At least the previous ones acknowledged that things weren’t changing as rapidly as predicted, if at all.
