New Paper from Roy Spencer: PDO and Clouds « Watts Up With That?

The evidence continues to mount that the IPCC models are too sensitive (produce too much global warming). If climate sensitivity is indeed considerably less than the IPCC claims it to be, then increasing CO2 alone can not explain recent global warming. The evidence presented here suggests that most of that warming might well have been caused by cloud changes associated with a natural mode of climate variability: the Pacific Decadal Oscillation.

I am posting this information in advance of publication because of its potential importance to pending EPA regulations or congressional legislation which assume that carbon dioxide is a major driver of climate change. Since the news media now refuses to report on peer-reviewed scientific articles which contradict the views of the IPCC, Al Gore, and James Hansen, I am forced to bypass them entirely.

We need to consider the very real possibility that atmospheric carbon dioxide - which is necessary for life on Earth and of which there is precious little - might well be like the innocent bystander who has been unjustly accused of a crime based upon little more than circumstantial evidence.
