I’m not sure how to write about An Inconvenient Truth without descending into a stormy, tearful rant, but I’m going to try not to do that. First, I don’t like the cynical, bitter, occasionally paranoid side of my personality that I’ve developed over the past six years. Second, I think such a response does a disservice to the movie and its subject, Al Gore. Yes, the documentary about Gore’s effort to educate people about the danger of global warning has moments of quiet anger, but it is no diatribe. In fact, one of the most inspiring aspects of the movie is that Gore — after winning the popular vote but losing the presidency to an unprecedented, party-line Supreme Court ruling — refused to become cynical, bitter, and occasionally paranoid; he decided to do something.
