Cloud study predicts more global warming

ScienceDaily (2010-11-23) -- Global climate models disagree widely in the magnitude of the warming we can expect with increasing carbon dioxide. This is mainly because the models represent clouds differently. A new modeling approach successfully simulates the observed cloud fields in a key region for climate. The study finds a greater tendency for clouds to thin with global warming than in any of the current climate models. This means the expected warming may be greater than currently anticipated.
