Cold weather due to global warming

Economist Paul Krugman, writing in the New York Times, has a bizarre position on the recent cold weather around the world.

[B]ad weather, especially the Australian drought, is probably related to climate change. So politicians and governments that have stood in the way of action on greenhouse gases bear some responsibility for food shortages.

Except that a lot of the crop failures have been due to cold weather. And anybody who has looked at the climate change issue for longer than thirty seconds knows you can't blame short-term weather fluctuations on climate change anyway. He's really just showing that he's a talking head rather than someone who has looked at the issues.

Jeepers. This is supposed to be one of the great American eminences grises.
