Read this carefully. No, not the "eat less meat" part. Ignore that for a minute, and take a look at the professional credentials of the chairman of the U.N.'s Intergovernmental Panel on Climate Change, Dr. Rajendra Pachauri. You would expect that such an elite position would be filled by an eminent climatologist with numerous citations in the literature, right?
Nope. He's an economist. While graduate level training is not always necessary to contribute in a certain area, the fact that the post is filled by an economist who wishes to reshape the world's economy ought to give us pause.
