Oh, another two points I was going to briefly bring up:
One, I am ABSOLUTELY in favour of renewable energy sources, however not because I believe co2 is causing global warming, but because we are on the verge (if we haven't already) reached peak oil, and that, my friends, is going to be a much more devastating event than a few celcius increase in tempurature, both for modern society and global economics. Also, I think burning fossil fuels is smelly and creates much worse pollution than some co2.
Second...I can't remember second anymore.
