So far, Al Gore has resisted the lure of presidency quite admirably (“Gore the Pure,” October 20, 2007). One can only hope that the Nobel peace prize will help him stay away from the race. Now that he has convinced so many Americans, as well as others around the globe, that climate change is a serious problem, his task must shift to something much more difficult: helping them figure out how best to tackle it. Although America has contributed to climate change more than any other nation, it is likely to contribute to the alleviation of climate change more than any other nation, as well. But that requires much knowledge and will. Without Gore’s help the difficult task of figuring out what works and what does not would be much more difficult. He is in a singular position to keep the entire effort on track. Once again, one can only hope the lure of presidency is already behind him, for his present job is almost certainly even more important than that of the president.
