Perhaps keeping the super alarmist/CAGW stuff in a separate thread would go a long way in helping tame the issues. I also have concerns about abrupt climate change, but the scientific evidence is thin (mostly because it's hard to gather evidence of such events on short time scales). Weatherguy, I agree that AGW will become catastrophic in a lot of ways, but it may not be for 30+ years.
That being said, the fact we are not moving to renewable fuels quicker as a globe is absurd.
