The head of the U.N.'s Intergovernmental Panel on Climate Change says he hopes last week's Nobel Peace Prize award will help put an end to the debate over whether human activity is causing global warming. Rajendra Pachauri spoke Tuesday at the panel’s headquarters in Geneva.

Rajendra Pachauri: “Adaptation requires resources, both technical, human and, of course, most importantly, financial. And since the poor countries of the world really don’t have the means on any of these three aspects, we are imposing a further burden on them, which I suppose as is implied in the Nobel Peace Prize, can threaten peace and security across the globe.”
