Volcanoes sometimes affect the climate severely by mechanisms other than carbon dioxide, but that's a story in itself.
A hell of a lot of carbon is moved around on this planet by natural processes other than volcanoes, and humans are a very small piece of the picture. I am in favor of alternatives to burning fossil fuels for energy, from the sheer waste of a valuable chemical resource if nothing else. I believe that nuclear power is an important part of this solution. I also believe that other alternatives will become available when the market is right for them and the technology is mature, and that the United States can handle this process on its own.
I am not in favor of putting the United Nations in charge of America's energy policy.
