NSF-funded study: Global warming rate less than IPCC estimates?

AFP: Global warming rate less than feared: study

High levels of carbon dioxide in the atmosphere may have less of an impact on the rate of global warming than feared, a study said Thursday.

The authors of the study funded by the US National Science Foundation stressed that global warming is real, and that increases in atmospheric CO2, which has doubled from pre-industrial standards, will have multiple serious impacts.

But the more severe estimates, such as those put forth by the United Nations' Intergovernmental Panel on Climate Change, are unlikely, the researchers found in their study published in the journal Science.
