Odd. Niether is this one...
Actually, our atmosphere used to be mostly CO2. Then some pesky little organisms evolved that converted it to O2, and the oxygen poisoned all the other little organisms.
The existance of global warming is not in dispute. However, wether or not it's caused by pollution is. There is no doubt that pollution isn't helping, but its quite likely it's a natural cycle. We're probably just speeding it up a bit.
It's still not as warm now as it was 2000 years ago. We've had TWO short 'ice ages' since then, the first dropped europe into the dark ages, and the second is responsible for those famouse new england winters in the 17 and 18 hundreds.
