Our Bipolar Icecap

Bring on the befuddlement:

On July 9, 1971, the Washington) Post published a story headlined "U.S. Scientist Sees New Ice Age Coming." It told of a prediction by NASA and Columbia University scientist S.I. Rasool. The culprit: man's use of fossil fuels. Sustained emissions over five to 10 years, Rasool claimed, "could be sufficient to trigger an ice age."

Aiding Rasool's research, the Post reported, was a "computer program developed by Dr. James Hansen," who was, according to his resume, a Columbia University research associate at the time. Hansen has some explaining to do. The public deserves to know how he was converted from an apparent believer in a coming ice age who had no worries about greenhouse gas emissions to a global warming fear monger.

My head hurts.
