I feel that as a citizen of the Earth, it is my responsibility to pass this on. If you haven't seen this video already, watch it. This man gives fair arguments for both sides (for/against global warming) and he does it all withough giving any specific details, and he makes a very good point.

If you have any opinion on global warming, be sure to watch it to the end.

Edit: Also, I did not see anything to argue or anything false that he said. If you feel something that is arguable please share.
