Study: Clouds' cooling role weakens in warmer world http://apocadocs.com/s.pl?1292005276
Until now one of the biggest uncertainties in climate change is whether a warming world will change how clouds regulate temperature. Will they trap more heat, or will they offer a net cooling by reflecting more of the sun's heat?
A Texas A&M University scientist, Andrew Dessler, has produced some of the first data to address this question, and his conclusion is that current climate models do a pretty good job of simulating the changing nature of clouds in a warmer world.
The new study, published Thursday in the journal Science, also appears to strike at a central tenet of some climate skeptics who believe clouds will offset much of the projected warming in a world with elevated greenhouse gases.
"Scientists are always thinking about where we could be wrong," Dessler said. "Clouds are one of the last places where scientists could really be wrong with respect to climate change. My work is really a first step toward removing this possibility.
"The opportunities for legitimate skepticism are drying up."

Those climate skeptics just have their heads in the clouds.
