Holding Off the Next Ice Age

Steven Hayward of Power Line quotes Obama science advisor John Holden from a Q and A session Holden did at the White House. Power Line also has a link to the video if you'd like to watch it.

While the climate of the earth has changed over the millennia as a result of natural factors – principally changes in the tilt and orientation of the earth’s axis and rotation, and in the shape of its orbit around the sun – those changes occur far too gradually to have noticeable effects over a period of mere decades. In their current phases, moreover, they would be gradually cooling the earth – taking us to another ice age – if they weren’t being more than offset by human-caused warming.

Translation: I'm doing y'all a favor by driving a big, ol' 1 ton pickup truck and two SUVs. I'm keeping the glaciers and the polar bears away from your door. Your thanks are gratefully noted.
