New peer reviewed paper: clouds have large negative cooling effect on Earth’s radiation budget (2011-09-20). Har, har. The word “feedback” is present in the URL of this post by Anthony, but no longer in the title… This is as close as Anthony gets to admitting he has once again jumped in with both feet, in haste and seeing only the conclusion that suited him.
Anthony’s certain that a new (peer-reviewed!!!!!!) paper by Richard Allan proves, once and for all, that clouds cause climate. So everyone can relax, those scientists were lying all along. Anthony claims that according to the paper:
a combination of satellite observations and models [show] that the cooling effect of clouds far outweighs the long-wave or “greenhouse” warming effect.
When the paper’s author, along with climatologist Bart Verheggen and even Roy Spencer point out that Anthony’s conclusion is not supported by anything in the paper, his fundamental response is a truculent “I saw things differently.” But why should he ‘fess up? Doctrinaire commenters such as ‘Roger Knights’, ‘Tall Bloke’, ‘RockyRoad’, etc will always praise his erroneous interpretation.
Could you please point out where in this paper it is mentioned that “clouds have large negative-*feedback* cooling effect on Earth’s radiation budget”?
Roy Spencer says, with what must be considerable pain given his ‘my science serves my [denialist] politics’ perspective:
Bart is correct. This paper is not about cloud feedback…it is about the average effect of clouds on the climate system, which the IPCC, Trenberth, Dessler, et al. will all agree is a cooling effect. It is an update of the early estimates from ERBE many years ago.
Richard Allan, the paper author, comments:
I was surprised that this paper was mis-interpreted as suggesting negative cloud feedback. This is a basic error by the author of the post that has been highlighted by many contributors including Roy Spencer.
Even the contrarian Steven Mosher had something interesting to say about the motives of Antony’s “skeptical” supporters (emphasis mine):
it is also fascinating because of what we dont see. usually you will see a whole crew of commeters pounce on the word “model”. This time they didnt.
They didnt because they thought the paper supported spencer. But it was on an entirely different topic. That misunderstanding kinda silenced the usual “models are bad” crew.
Thanks to my commenters for drawing this entertaining post to my attention. It’s a classic example of Anthony’s enthusiastic ignorance. I’ve been overloaded with work and with supporting the recently concluded Toronto International Film Festival and would have missed this…
