For those of you who didn't see AN Inconenient Truth - yes ... haha, it's Al Gore presenting this. Does that make it less true? No.
There's a particularly alarming piece of information in his presentation - a graph of C02 levels, for iirc the last 600,000 years. He shows how temperature trends follow C02 levels for all that time. He also shows that current C02 levels are about twice as high now as ANY TIME IN THE LAST 600,000 YEARS. I think that's extremely telling, that we are having a major impact on the world's environment - this is not just a natural cycle. Go see the movie.
