Oops: Modeling error due to ignoring cloud effects may be 216 times larger than the alleged effect of doubling CO2 concentrations

THE HOCKEY SCHTICK: Settled science update: Climate models make 'very large' errors in determining solar radiation at Earth's surface, 'ignore the effect of clouds'

A paper published today in the Journal of Geophysical Research finds that current global climate models make "very large" errors in determining solar radiation at the surface of the Earth "due to ignoring the effects of clouds." According to the authors, these very large errors can exceed 800 Watts per meter squared, which by comparison is about 216 times more than the alleged effect of doubling CO2 concentrations [3.7 W m-2].
