Global Warming Starts to Divide G.O.P. Contenders

"While many conservative commentators and editorialists have mocked concerns about climate change, a different reality is emerging among Republican presidential contenders. It is a near-unanimous recognition among the leaders of the threat posed by global warming.


Within that camp, however, sharp divisions are developing. Senator John McCain of Arizona is calling for capping gas emissions linked to warming and higher fuel economy standards. Others, including Rudolph W. Giuliani and Mitt Romney, are refraining from advocating such limits and are instead emphasizing a push toward clean coal and other alternative energy sources.

Mike Huckabee of Arkansas and Senator Sam Brownback of Kansas, call for strong actions to ease the effects of people on the climate, at times casting the effort in spiritual terms just as some evangelical groups have taken up the cause.

The emergence of climate change as an issue dividing Republicans shows just how far the discussion has shifted since 1997, when the Senate voted, 95 to 0, to oppose any international climate treaty that could hurt the American economy or excused China from responsibilities.
