In a surprise U-turn, the Republican senator has put forward a bill to review the dangers of black carbon to health and the environment.
He has called global warming a hoax, compared the Environmental Protection Agency with the Gestapo, and over the years dismissed Al Gore as desperate and "full of crap". So it was startling when America's arch climate change denier came out ahead of the green curve in the fight to save the Arctic and other icy regions.
Could James Inhofe, a conservative Republican senator from Oklahoma, be the newest recruit to Barack Obama's green revolution?

Inhofe, in a surprise move, joined Democratic senators in putting forward a bill for an official review of the dangers of soot or "black carbon" to public health and the environment late last month.
