I would point out that I've always believed the climate changes. It's been doing so for millions of years and will continue well after humanity's demise.
I'm still not sure (1) how much of that (as a % of total) is "our" fault and (2) how much of the climate we can "control"
My contribution to the green movement is primarily through conservation. Because I'm too much of a cheapskate to pay for wasted energy (like leaving the lights on, driving a gas guzzler, etc)
X2, I believe things change in cycles and I am not sure humans can contribute much towards the change in either direction. Plenty of instances in recorded history where places were once warmer (and cooler) than they are now.
