I would not be too sure how quick it can or has changed in the past. Check the geological record.
I will agree that man can and has changed the planet a lot and quickly. Lowering the impact is always a good idea.
However as for man made global warming, it is more of faith than proven science. You can look at whatever data you want to cherry pick and say there's your proof, but this is like one side saying the glass is half empty. Yes it is, but then what about the part that is half full? I am only saying you need to see it is half empty and half full.
What I am saying is there is evidence to both support the global warming theory and disprove it. So really the verdict is still out.
Some time back they were saying we were headed for another ice age. I guess you at least believe they were wrong. Then hind sight is 20/20.
I just think people need to take a step back and look some more at all of the data before they put faith in it one way or another.
