Probably because CO2 is much heavier than air so it is more abundant in the lower layers of the atmosphere, and more rare in the higher layers...

To the OP: The problem with this question is that it is very much ideologically charged (probably as much as the MMJ debate) and so both sides simply ignore the facts the other side shows and cling to their positions. So i wont waste my time getting "facts" (or rather sites/videos/whatever on the internet), cause i know no amount of "facts" can change your (or anybody elses) mind if you dont want to. Also, nowadays its possible to back up almost anything with internet "facts", as the MMJ debate shows very well. Anyway, if you want internets "facts", look at Al Gores site, for example.

But, lets suppose for a moment that you are right, and the climate changes caused by humans are still too small. If the worlds industrialization keep its pace, how long it will take until all the things that the environmentalists claim now became actually true? How it will be when every inhabitant of the 3rd world were able to drive its car? How it will be when all the forests were turned into farms/fields/whatever? If the world still wasnt messed up enough by society, is it an excuse to keep messing it up?

If you want to know, i actually think the environmentalists are a bit exagerate (much like the defenders of MMJ that says its a completly harmless thing), but i think its needed. Maybe mankind still can revert (or at least diminish) the impacts of its society on the environment, but for do this it must start to act NOW. This things takes a very long time to change. If we keep living as if there werent tomorrow and wait until the problems knock on our doors to think about them, then surely it will be too late to do anything.
