Wait, what?!: Revkin wrote in Aug. 2000 that James Hansen fingered other emissions, NOT CO2, for the warming seen in recent decades

Study Proposes New Strategy to Stem Global Warming - New York Times
An influential expert on global warming who for nearly 20 years has pressed countries to cut emissions of carbon dioxide and other heat-trapping gases now says the emphasis on carbon dioxide may be misplaced. Instead, he and a team of scientists have concluded that the quickest way to slow warming is to cut other such greenhouse gases first.
The expert, Dr. James E. Hansen, and his colleagues conclude in a new analysis that the warming seen in recent decades has been caused mainly by other heat-trapping emissions -- methane, chlorofluorocarbons, black particles of diesel and coal soot and compounds that create the ozone in smog -- which are easier to control than carbon dioxide, with many of them already on the decline.
''The prospects for having a modest climate impact instead of a disastrous one are quite good, I think,'' Dr. Hansen said in an interview.
