What the Hell?

Can anyone give me the ten-second elevator speech about this latest climate controversy--the one involving Eric Steig and Ryan O'Donnell? That would be the speech going up. Then on the way down, can anyone give me another primer on why this dust-up matters? I'm serious. When even this guy calls it an "incredibly complicated story" then I know it must be complicated. For bonus points, please direct me to any sites that you think present this "incredibly complicated story" in a fair and evenhanded manner. UPDATE: Steig responds in full to the controversy over at RC. Will it quiet the mob? I'm sure we'll find out in no time. UPDATE: Andrew Revkin has a nice meta overview post at Dot Earth.
