For several years, Roy Spencer has been promoting some work he did which he claims shows that the feedback from clouds is negative. Spencer has been a vocal critic of the science of climate change and he works are frequently referenced by denialist, such as Rush Limbaugh. Here's a link to Spencer's 2010 paper:
http://www.drroyspencer.com/wp-content/uploads/Spencer-Braswell-JGR-2010.pdf Spencer has even written a book about his thinking, " The Great Global Warming Blunder: How Mother Nature Fooled the World’s Top Climate Scientists ". It now appears that Spencer's work is seriously flawed, according to an analysis by geologist Barry Bickmore, which he presents in three parts on his blog: http://bbickmore.wordpress.com/2011/02/25/roy-spencers-great-blunder-part-1/ Worse yet, another analysis by Arthur Smith goes to the heart of the situation with a detailed look at the math: http://arthur.shumwaysmith.com/life/content/mathematical_analysis_of_roy_spencers_climate_model For those in the US who might be interested, results from Spencer's analysis was just used by John Christy in his presentation before the US House Committee Energy and Commerce Committee. Here's a link, (see graph on page 17): http://republicans.energycommerce.house.gov/Media/file/Hearings/Energy/030811/Christy.pdf The hearing is about H.R. 910, which prohibits the EPA imposing any regulation of greenhouse gases. It would appear that the Republicans in the House are working with improper information as they set out to destroy the EPA's efforts to limit emissions of greenhouse gases. The bill just passed out of the committee and is headed to floor for a vote by the full house. The Republican War on Science continues and all humanity will all "enjoy" the results... E.
