I would not advice anyone to watch Al Gore's power point talk on global warming. He gets both Hollywood award as well as the Nobel prize for his show. Al Gore is a phony- he lives in a 10,000 sq. ft house, rides big vans, and talks big about global warming. Global warming may be a fact, but Al Gore is the wrong person to talk about it- he is barely educated failed politician who is full of hot air- that contributes to global warming.
