I didn't catch it, but I'm sure it's the same as everything else. Global warming blah blah blah.....asteroids blah blah blah....It's all the same. The world will end eventually. No use worrying about it, the fact that we thin we might be able to stop or change the natural cycle just shows our arrogance. If I had to choose, I'd have to bet on either asteroids or gamma rays. Either way, I'll be dead before I know what happened. I just hope I'm gone before the next global climate shift (its gonna happen). FL won't be so much fun when its frozen over.
