Hot off the press: Dessler's record turnaround time GRL rebuttal paper to Spencer and Braswell

UPDATE: Dr. Roger Pielke Sr. has a comment on the paper here: Comments On The Dessler 2011 GRL Paper “Cloud Variations And The Earth’s Energy Budget also, physicist Lubos Motl has an analysis here. The press release from TAMU/Dessler has been pushed to media outlets on Eurekalert, see update below.

UPDATE2: Dessler has made a video on the paper see it here And Steve McIntyre has his take on it with The stone in Trenberth’s shoe

I’ve been given an advance copy, for which I’ve posted excerpts below. This paper appears to have been made ready in record time, with a turnaround from submission to acceptance and publication of about six weeks based on the July 26th publication date of the original Spencer and Braswell paper. We should all be so lucky to have expedited peer review service. PeerEx maybe, something like FedEx? Compare that to the two years it took to get Lindzen and Choi out the door. Or how about the WUWT story: Science has been sitting on his [Spencer’s] critique of Dessler’s paper for months”.

If anyone needs a clear, concise, and irrefutable example of how peer review in climate science is biased for the consensus and against skeptics, this is it.

I’m sure some thorough examination will determine if the maxim “haste makes waste” applies here for Dessler’s turbo treatise.

Cloud variations and the Earth’s energy budget

Abstract: The question of whether clouds are the cause of surface temperature changes, rather than acting as a feedback in response to those temperature changes, is explored using data obtained between 2000 and 2010. An energy budget calculation shows that the energy trapped by clouds accounts for little of the observed climate variations. And observations of the lagged response of top-of-atmosphere (TOA) energy fluxes to surface temperature variations are not evidence that clouds are causing climate change.

Introduction

The usual way to think about clouds in the climate system is that they are a feedback — as the climate warms, clouds change in response and either amplify (positive cloud feedback) or ameliorate (negative cloud feedback) the initial change [e.g., Stephens, 2005]. In recent papers, Lindzen and Choi [2011, hereafter LC11] and Spencer and Braswell [2011, hereafter SB11] have argued that reality is reversed: clouds are the cause of, and not a feedback on, changes in surface temperature. If this claim is correct, then significant revisions to climate science may be required.

Conclusions

These calculations show that clouds did not cause significant climate change over the last decade (over the decades or centuries relevant for long-term climate change, on the other hand, clouds can indeed cause significant warming). Rather, the evolution of the surface and atmosphere during ENSO variations are dominated by oceanic heat transport. This means in turn that regressions of TOA fluxes vs. ΔTs can be used to accurately estimate climate sensitivity or the magnitude of climate feedbacks. In addition, observations presented by LC11 and SB11 are not in fundamental disagreement with mainstream climate models, nor do they provide evidence that clouds are causing climate change. Suggestions that significant revisions to mainstream climate science are required are therefore not supported.

UPDATE: Here is the press release from Texas A&M via Eurekalert:

Texas A&M University

Texas A&M prof says study shows that clouds don’t cause climate change

COLLEGE STATION, Sept. 6, 2011 — Clouds only amplify climate change, says a Texas A&M University professor in a study that rebuts recent claims that clouds are actually the root cause of climate change.

Andrew Dessler, a Texas A&M atmospheric sciences professor considered one of the nation’s experts on climate variations, says decades of data support the mainstream and long-held view that clouds are primarily acting as a so-called “feedback” that amplifies warming from human activity. His work is published today in the American Geophysical Union’s peer-reviewed journal Geophysical Research Letters.

Dessler studied El Niño and La Niña cycles over the past 10 years and calculated the Earth’s “energy budget” over this time. El Nino and La Nina are cyclical events, roughly every five years, when waters in the central Pacific Ocean tend to get warmer or colder. These changes have a huge impact on much of the world’s weather systems for months or even years.

Dessler found that clouds played a very small role in initiating these climate variations — in agreement, he says, with mainstream climate science and in direct opposition to some previous claims.

“The bottom line is that clouds have not replaced humans as the cause of the recent warming the Earth is experiencing,” Dessler says.

Texas is currently in one of the worst droughts in the state’s history, and most scientists believe it is a direct result of La Niña conditions that have lingered in the Pacific Ocean for many months.

Dessler adds, “Over a century, however, clouds can indeed play an important role amplifying climate change.”

“I hope my analysis puts an end to this claim that clouds are causing climate change,” he adds.

Now that Wagner has seen Dessler’s paper, I bet he asks for reinstatement to his (honorary) editor’s job. I hope he does it with real panache, the way he resigned.

It’s funny, it’s struck me today more than ever – as Europe is collapsing, as the US markets are collapsing, as the economy is collapsing, as the entire concept of efficient government contol of anything worldwide is collapsing…
this entire argument is such an ingrown, overhyped screamfest of nonsense! Not that Anthony’s doing anything wrong in opposing the lies, far from it! The lies must be opposed. But all in all, this issue is just kabuki theatre, full of sound and fury, Signifying Nothing.
It’s like watching WOW players argue about which magical attribute is more powerful. To the wide world at large, the answer is; Who could possibly care anymore? These scientific journals? I expect almost all of them to be gone in 10 years, or less. None of this will even be remembered.
And for those who would argue that well, it’s because of where government funding will go, that could be a point; except that we have now reached a state where there is going to be NO new government funding for anything, for any of us, for a very long time.

I have stated before that IF the next decade is cooler than 2000-2010 then I would at least doubt AGW theory, or be looking for negative factors impacting the extra thermal energy retained by the additional CO2.
What pattern of global temperature change would cause ypou to doubt your position ???

My position is that the world has been coming out of a Little Ice Age and is following a cooling pattern as the ice core records of the holocene show . Actually the whole series of plots are sobering, showing that the world has been hotter and cooler many times than our small time interval in our small lifetimes would let us think.
My position on anthropogenic warming is that it is hyped beyond recognition of the real physics behind it . Btw I am a physicist, and have really delved into the physics of the IPCC AR4 claims, and know that physics has been abused in a cavalier fashion by the GCModels used to predict catastrophic heating. In addition since the past ten years the temperature is in stasis while CO2 is merrily growing apace, the naive correlation=causation of the IPCC climatologists has been refuted by the data, as have another six or seven projections of their model. Even one wrong prediction sends an analysis back to the drawing board. Instead climatologists torture the data to try and fit their models willy nilly, which is another ridiculous use of “science”.
I cannot see my position changing on this, as I have spent enough time thinking about it and checking the claims.

Whilst it does appear that Dessler has made a total pratt of himself it is entirely irrelevant. He could have written the story of the three bears in the paper. The fact is that the Journal Editors will now close ranks to prevent any riposte from Dr Spencer, the MSM will shout “SB11 destroyed, move along now, nothing to see here.” The gatekeepers will breath a sigh of relief. The BBC pension fund will be saved. The IPCC will carry on as normal. All will be well with the world until the next sneaky underhand attempt to promulgate truth as opposed to doctrine slips past the teams goalkeeper.

Here is the two-year NSF grant Dessler has also exploited for this research:

Check the number, AGS-1012665, that it agrees with the acknowledgements in the paper. Aside from those $150,000 for less than two years (bad luck, dear U.S. taxpayer: you were not carefully watching your wallet!), he is probably getting a similarly large extra salary from Texas A&M University, too.

“So, why did the Warmista give up incrementalism? And please do not trot out that tired old menagerie of excuses about climate being chaotic, holistic, or enlightened.”
“For the same reason we don’t expect incrementalism in the seasonal changes. The solar energy arriving at the surface may be changing incrementally as axial tilt and orbital position cause seasonal change, but the actual temperature does NOT change incrementally. It can be warmer in April than in May, or colder in October than November. Only by taking the average over 10 days or so can you find the incremental seasonal change buried in the daily variation.”
Aha, you have been totally and successfully trapped. You responded by creating an analogy that tells the story of the seasons, some physical facts on Earth. Notice that you cannot do the same thing by reference to CO2 concentration and temperature alone. You cannot because there is no consistent interpretation of Warmista claims about CO2 concentrations and temperature in terms of actual observable events on Earth. In sum, Warmista claims about CO2 concentration and temperature have no connection to observable reality whatsoever.

“I know causation can become a slightly problematical concept in QM, but unless you are going to invoke temporal loops around singularities there is no logical possibility that if A causes B then B also causes A. It would require a causal influence to travel BACK in time.”
When Spencer says “clouds influence temperature AND temperature influences cloudiness” he does NOT imply that a particular cloud traveled back in time, izen. Rather, it’s different clouds at different times. Get the concept?
==================================================
Dirk, I think he’s being intentionally obtuse. Anyone suggesting clouds operate unidirectional and only work to increase the temps denies evidence that anyone can observe, and is perilously close to being delusional.

Studying an isolated natural event of a still uknown cause, than claiming clouds only partly cause it, does not mean that global increases in temperature will cause a positive cloud feedback – its like studying a single rock in a river and concluding what the river will do over its length based on the shape of the rock. Observation actually proves the opposite from what I have seen.

Anthony,
Les Johnson did us all a great service by summarizing the sequence of events (to that point in time) which you then posted as the “Journal Deliverance” thread. I’d like to see that approach continue. This thread for example has plenty of good information in it, but unless one has followed ALL the details from beginning to end, much of it is out of context. Some readers have the big picture, but I suspect many are drowining in details and losing site of it. I haven’t them time to give credit where credit is due, nor research the exact dates of each event (perhaps Les would continue his yeoman’s work in that regard?) but here is my summary:
Some of the following is conjecture based on circumstancial evidence, but in my mind, no other logical explanation has arisen:
o Spencer and Braswell published a paper (SB11) which looked at satellite measurements of the earth’s radiative balance and concluded that the climate models were under estimating, to a significant degree, the amount of heat energy being lost to space.
o The paper was properly peer reviewed, flaws discovered in the peer review process which were corrected, and the paper was published in Remote Sensing.
o A few weeks later, the Editor-In-Chief of Remote Sensing, one Wolfgang Wagner, resigned, citing his objections to SB11 as the reason. Upon review, the reasons detailed in his resignation article on the Remote Sensing web site made little or no sense. Not one single fact presented in the SB11 paper was refuted, Wagner confirmed that the reviewers were qualified and from prestigious universities, speculating only that they “may” have held skeptical positions. The wording of the resignation, and the surrounding circumstances, suggest that Wagner attempted to have the SB11 paper retracted, failed to do so, and being unable to impose his will on Remote Sensing, resigned his position as Editor-In-Chief.
o The only portion of Wagner’s resignation that appears to be genuine is his claim that SB11 was not credible because the modeling community was not consulted about the results. While this appears to be a genuine statement on his part, the logic suggested is a fallacy. SB11 was the result of actual measurements. Models are beholden to actual measurements, not the other way around. Models are simulations of the real world, and when measurements of the real world are made, they stand on their own, because they are, in fact, measurments of the real world, not computer simulations of how some scientists think the world really works.
o Upon further investigation, it became apparent that Wagner’s position at Remote Sensing was largely that of figure head. His full time employment and day to day job is with the Vienna University of Technology, where he holds a position that stands at the cross roads of two important disciplines. These are listed on the VUoT web site as “remote sensing” and “environmental modeling and 3D modeling”. Wagner is listed as “physical modeling” and is depicted as the centre piece by which the three disciplines are integrated with each other.
o This makes the following logic chain plausible, and in the absence of any other logical explanation, likely. The SB11 paper presents actual measured data showing that the models are over estimating global warming, discrediting much of the CAGW propoganda in the process. Beholden to the modeling “camp” upon which cooperation with for his day to day job depends, Wagner was pressured into attempting to have the SB11 paper blocked or retracted. Having failed to do so, Wagner resigned, and his resignation article reads far more as an apology to the climate modeling community than as a professional resignation, and is clearly meant as an attempt to appease the climate modeling community which SB11 so clearly destroys the credibility of.
o Not long after Wagner’s resignation, Kevin Trenberth, a leading light in the climate modeling community, initiated a smear campaign against Dr Roy Spencer. The smear campaign included any number of criticisms of Spencer, Braswell, and (for some unknwon reason as he was not involved in SB11) Dr Christie. But astoundingly, not a single word about the science itself in SB11. More astoundingly still, Trenberth was not content to simply smear Spencer, Braswell, and Christie. He went on to brag about having recieved a personal apology from the Editor-In-Chief and the Publisher of Remote Sensing.
o Kevin Trenberth is, amongst other things, the chair (by acclamation, which shows his clout in the modeling community) of the prestigious GEWEX intitiative which seeks to model moisture levels on a global basis. Wagner in turn heads the soil moisture global modeling initiative at VUoT, which is directly beholden to GEWEX for day to day cooperation and integration of data with modeling, and without GEWEX support, Wagner’s soil moisture database would be in jeapourdy from a credibility stand point, if not from a fudning stand point.
o Logic dictates that this chain of events supports still more conclusions for which there is no alternative explanation that reasonably fits the facts and sequence of events. For starters, the wording of Trenberth’s smear campaign suggests that the Editor-In-Chief and the Publisher are two different people, when in fact, they are one and the same. Only a single apology was recieved, and it was from Wagner and only Wagner. The editorial board of Remote Sensing has clearly decided to stand behind their publication in general, and SB11 in particular. TRenberth in the meanwhile gloats that he has recieved and apology from Wagner, implies that it is from more than just Wagner when it clearly isn’t, and through his various comments, seems to be taking pride in destroying both SB11 and Wagner without raising a single solitary scientific fact in the process. Wagner’s resignation and apology are both panic stricken attempts to appease someone with more power than himself and regain that person’s favour.
o Trenberth’s one and only sop to actual science is to claim that the forthcoming paper from Dresller would eviscerate SB11. So now, here in this thread, we have excerpts from the paper, and the weight of many extremely qualified researchers to rely upon for analysis. The short version? Dressler’s paper makes a mockery of science, the scientific process, and flies in the face of the facts themselves.
o The Dressler paper is founded upon criticism of statements and claims never made by SB11. In some places it actually refutes itself. The analysis is restricted to a time period in which almost no measurable change in temperature has occurred, and concludes that SB11 is wrong as a result, and the models right. the simplest of persons should be able to see straight through this concoction of misrepresented facts and logic. The models have all predicted massive temperature increases over that exact time period, and have ALL BEEN WRONG. To suggest that measurements showing WHY they are wrong can be negated by the fact that the time period in question exhibted no significant change IN DIRECT OPPOSITION TO WHAT THE MODELS PREDICTED is repugnant beyond words. They may as well have told a man dying of thirst in the middle of the Sahara that it is pouring rain, and when he gasps that he sees no rain, just blue sky and sand, respond back that his perception of the real world must be wrong, and had he bothered to consult with the models, he would be able to understand, silly fool that he is, that it is in fact pouring rain.
o WaterGate was a cover up which lent its name to many cover ups since then, possibly the most notable being the ClimateGate emails. But this entire affair goes well beyond a cover up. Wagner’s resignation and his apology to Trenberth are clearly the results of a cowardly attempt to appease the climate modeling community in general, and Trenberth in particular. In doing so, Wagner has destroyed his own credibility as a scientist, and exposed the power that Trenberth and his allies are prepared to wield in order that their climate models be accepted as reality, while reality itself is discredited. In neither WaterGate nor ClimateGate however, did the authors of the dirty deeds gloat, in fact brag, publicly, about what they did. Trenberth’s smear campaign, and Dressler’s idiotic attack on things that SB11 never said, while strictly avoiding what SB11 DID say, are not a cover up. They are a demand that the man dying of thirst in the Sahara believe that it is raining because their computer models say it is, and that he should apologise to them for both dying and being thirsty.
o Trenberth has publicly admitted that his models cannot account for “the missing heat”, a matter which he dubbed a “travesty”. Faced with clear measurements of exactly where the missing heat is going, the one option that Trenberth refuses to consider, that the heat is escaping to space instead of being retained as his models claim, Trenberth has stooped low enough to scratch the belly of a snake. He, along with Dressler, have proclaimed the very lack of warming that disproves their dearly beloved models is at the same time proof that their models are right in the face of actual measurements showing not only that they are wrong, but where the “missing heat” they themselves admit has gone. Nixon had the guts to proclaim on national television that he wasn’t a crook. Not even Nixon would have had the guts to proclaim himself a crook, and innocent as a consequence of being a crook.
o This is no “gate” nor “travesty”. Stronger words than that are needed.

Perhaps the devotion to computer climate models is what makes the climate boffins view the real climate as a digital system. The real world climate is analog not digital.

Maybe the most relevant and important observation of all “.. the real world climate is analog not digital” … these modelers try to force an analog system with all the “chaos” involved into a black and white “digital” form … all but impossible when there is no clear understanding of even all the underlying processes and relationships
Which is clearly shown by the fact that every model requires a significantly different number for anthropogenic effect to “match” the real world

This makes absolutely no sense!
summarizing what each said:
Spencer and Braswell: Clouds are both, a feedback but also a driver of long term and short term climate change.
Dessler: Cloud-cover affects short term climate change less than, ocean currents. Because the effect is smaller, it is not a driver and only a feedback. Therefore humans cause climate change.
S. and B. never denied that ocean currents affect the short term climate.
Dessler made these 3 errors:
1. The magnitude of the short term influence of cloud-cover is no indicator of weather or not it is a driver or only a feedback.
2. Effects with large short term amplitudes do not necessarily have large long term amplitudes. (oszillations such as seasons, El Ninio, etc.)
3. His conclusion, that humans cause climate change has no base in his argument. He did not show, how humans changed the ocean currents.

We live on a street corner in San Diego. In order to save water, the border between the sidewalk and curb on one of the streets is not irrigated. We had a very rainy winter, and grass/weeds grew long, lush and green in the border. One short stretch along the border is shaded by a huge ficus all the way to the curb. At this point, all the border vegetation is dead (and mowed) except for that in the shaded area, which is still somewhat green, and growing.
I’m curious as to the role atmospheric CO2 plays in the varying states of vegetation vitality in my border.

Like Fred Haynie, I am excited about the papers by Spencer and Braswell because they bring this issue to the fore, though they might not do it directly. I am more excited because revealing the Warmista ontology reveals that they will never have physical hypotheses about cloud behavior.

Yes, finally the skeptics are forcing their opponents to engage in a back-and-forth, full-fleshed debate about their arguments, instead of being able to get away with a dismissive once-over. I hope that S&B will call for an evaluation of the arguments by a panel of distinguished retired scientists in related disciplines. That would stop current gatekeepers from being able to keep a lid on debate and implicitly declare victors. The battle should be taken to another level.

nope! consider your classic introductory diffi-Q predator-prey model.
The predator population affects the rate of predation which affects the prey population which in turn affects growth rate of the predator population.
So over time (going forward only, no sigularities needed!) the predator population affects the prey population and vice versa. Though not a climate scientist (obviously, or I would be denial of this effect… hehe), I believe that this predator/prey model is likely not a bad analogue (grossly simplified) to the interaction between clouds and climate.
