In Obama’s Team, 2 Camps on Climate

WASHINGTON - In the fall of 1997, when the Clinton administration was forming its position for the Kyoto climate treaty talks, Lawrence H. Summers argued that the United States would risk damaging the domestic economy if it set overly ambitious goals for reducing carbon emissions.

Mr. Summers, then the deputy Treasury secretary, said at the time that there was a compelling scientific case for action on global warming but that a too-rapid move against emissions of greenhouse gases risked dire and unknowable economic consequences.
