Combating Global Warming Needs U.S. Participation

"The best that can be said of the recently concluded meeting on climate change in Montreal is that the countries that care about global warming did not allow the United States delegation to blow the whole conference to smithereens. Washington was intent on making sure that the conferees required no more of the United States than what it is already doing to restrain greenhouse gas emissions, which amounts to virtually nothing...Why should India and China make major sacrifices while the United States, in effect, gets a free ride? The battle against global warming will never be won unless America joins it, urgently and enthusiastically."
