I don't think Al Gore deserves the Prize and here's why:
He made a movie about Global Warming. Yippee. The movie was pointless: it didn't educate anyone or make a difference. People who know or are concerned about global warming were already concerned/knowledgeable about it before the movie came out. For everyone else, the movie was the beginning to a plethora of punchlines. He hasn't greatly spread awareness, and you know what? He hasn't FIXED it! So what's the point? The Prize should go to the person who actually fixes the gorram hole in the Ozone...or to the pharmaceutical companies, whose products keep the American public docile little zombies. THAT is a peace movement.
(In case you missed the sarcasm, let it be known that I think the Nobel Peace Prize is a complete sham to begin with...this Al Gore event is just the clincher)
Besides...we all know that he deserves to be recognized with the Prize for his REAL contribution to society: the internet.
