On September 21, 2007, Investor's Business Daily published an editorial that suggested that NASA's Dr. James Hansen previously supported a theory that a new ice age was fairly imminent. The newspaper wrote:

Did NASA scientist James Hansen, the global warming alarmist in chief, once believe we were headed for . . . an ice age? An old Washington Post story indicates he did...

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.

That account appears at odds with the story it cites. The Washington Post's article stated:

They [Dr. S.I. Rasool and Dr. S.H. Schneider] also had available a computer program developed by Dr. James Hansen there to study the optical properties of the clouds of Venus. They applied the same program to make what Rasool called the first sophisticated calculations of fuel dust's sunlight-scattering properties.

That's the only reference The Post made to Dr. Hansen. There is no mention that Dr. Hansen supported the ice age argument. Moreover, the scientists who reached that conclusion were using a program Dr. Hansen developed "to study the optical properties of the clouds of Venus," a qualification that Investor's Business Daily omitted.
