"Loss of Reflectivity in the Arctic Doubles Estimate of Climate Models"

Global warming is a bigger problem than we thought -- and it was already bigger than we seem to be able to handle:

Loss of reflectivity in the Arctic doubles estimate of climate models, EurekAlert: A new analysis of the Northern Hemisphere's "albedo feedback" over a 30-year period concludes that the region's loss of reflectivity due to snow and sea ice decline is more than double what state-of-the-art climate models estimate.

The findings are important, researchers say, because they suggest that Arctic warming amplified by the loss of reflectivity could be even more significant than previously thought. ...
