I'm still a skeptic of human driven global warming. Yes, carbon dioxide levels are going up but I'm not convinced that it is entirely due to fossil fuel combustion. Yes, I am aware of the isotopic carbon argument C12 and C13 enrichment relative to C14 because fossil fuels are old carbon and the C14 has decayed out. The problem I have with that is the assumption that fossil fuels are the only source of old carbon entering in the atmosphere.
These climate treaties and whatnot have always been about the transfer of wealth from rich to poor nations.
