the earth's warming / cooling cycles, including effects of the sun, take centuries if not millennia to play out, with significant change taking vastly long times on a human timescale. the fact researchers are seeing RATES of temperature change never before seen over a half a million year time period points to some other factor at play other than natural cycles.[QUOTE="comp_atkins"]

There really isn't any way to prove that the Earth is warming only because of humans though. And if one believes in evolution, warming is an entirely natural effect since humans survive by depleting/modifying the environments around them.
If humans weren't present on planet Earth, there would still come a day when Earth could no longer be sustained.

I agree with what you're saying, but mankind's effect on the planet is part of that natural cycle. To think there is some way for humans to exist in any fashion even close to how we do now and for us to be completetly non-harmful to the environment is silly. It's one or the other; either humans go or they'll continue to be harmful. That's about as much of a fact as anything else spouted around in this thread.
Damage control is possible, but not an end-all answer.
agreed.. at best we can seek to mitigate the effects of our actions so that future generations don't, you know, inherit a s--thole :P
