I have done a lot of research over time on global warming.
Do I think mankind has contributed to greenhouse gas buildup? Certainly. Do I think the natural processes of the planet - such as volcanic eruptions - do far more? Absolutely. Do I know that huge climate shifts have occurred un the past without anything mankind has done to contribute to it? Of course.
Climate change happens. Ice ages. Periods of warming. I honestly do not think that there is anything man can do to prevent it.
Kyoto has always bothered me in a few ways - developing nations, such as India and China, huge polluters in that they primarily get all their power from coal burning, are exempt. Also, I have read that Europe, in attempting to comply with Kyoto goals, actually increased their production of greenhouse gasses by 1.1 percent over the last few years, a far cry from any reduction.
Here is a link that I find interesting, from a source that I find it odd to be citing based on my politics, but it is certainly a different idea and seemingly feasible. The idea is to extract excess carbon dioxide from the air and sotre it.

The only chance we have of reducing emissions is to go nuclear. If we powered as much of our eletrical needs from nuclear power as France does (79%), that would drastically reduce emissions from coal burning.
Anyway.....like I said, climate change happens, and I don't think man did anything to cause it before, and I don't think we could ever do anything to stop it. It's the way good old earth has worked for a long time.
