That's why The Day After Tomorrow bugged me. I mean, it was a great set-up for a movie, but I think it totally destroyed the credibility of the reality of global warming. FYI, for those unaware, when the climate does change, it's not going to happen with fuel in people's tanks freezing in ten seconds and walls of ice chasing people down corridors.
That, and the ending sucked. It's like "Oh, it was just a really, really, really bad storm...?"
