I think it's interesting that a New Mexico Senator would think that it is in his state's interest to curb CO2 emissions because of drought. Actually, because of the impact of air conditioning, population growth, illegal immigration, and the housing boom, New Mexico needs increased energy use more than most states. Other states might have to subsidize his anxiety. A Kyoto treaty type solution will have no impact on New Mexico droughts:
1. It won't have an affect for decades until the adaptive tech will have improved dramatically (assuming continued economic growth)
2. Kyoto and US emissions have no effect on the Third World. In fact, any oil we don't use will be used there.
It is also possible, however, that Domenici favor nuclear power, which has promoted at times in the past.
