New Study Finds Computer Models Predict Too Much Warming

Published August 17, 2011

A doubling of atmospheric carbon dioxide concentrations will likely cause roughly 1 degree Celsius of global warming, as opposed to United Nations computer model predictions of 1.5 to 5 degrees of warming, concludes a new peer-reviewed study authored by MIT atmospheric science professor Richard Lindzen and South Korean environmental science professor Yong-Sang Choi. 

Lindzen and Choi analyzed radiation escaping into space as measured by NASA satellite instruments, sea surface temperatures, air temperatures, humidity, and other factors to produce a temperature sensitivity model that better replicates real-world conditions than United Nations computer models and indicates less future warming than UN computer models.

Meteorologist Anthony Watts presents a good summary of the Lindzen-Choi paper here, and the full text of the study is available here.
