Working Group I of the Intergovernmental Panel on Climate Change (IPCC) released the summary of its report on the physical basis of climate change on 2 February. The report arrives at a time when the debate in U.S. political circles has shifted from the existence of climate change to methods of mitigation and adaptation.
Much of the past debate among U.S. politicians had focused on whether climate change exists and whether humans are responsible. But even some politicians who once were skeptical now find themselves believers. “It is hard not to be persuaded by the evidence,” said Rep. Bob Inglis (R-S.C), who credited his change of heart on the growing body of scientific evidence and a recent trip to Antarctica. Inglis spoke at an 8 February hearing of the U.S. House of Representatives Committee on Science and Technology.
