The Day After Tomorrow

I don't honestly see how effective this movie could be in teaching people the possible consequences of global warming. Climate changes take place over hundreds of years, and sudden climate changes (the kind in this movie) take place over a period of decades. Global warming isn't going to cause buckets of hail to suddenly drop on Japan, and it's not going to cause New York to flash-freeze. Global warming will raise ocean levels, flooding coastal marshes, which in turn will only force those same marches to move further inland. Global warming will cause higher and lower temperatures in hotter and colder areas respectively because of droughts and the possible slowing or shutdown of the thermohaline ciculation.

I haven't seen this movie yet, but I intend to. I intend to watch it solely for the special effects, because the entire premise of the movie is just a bit too silly to take seriously.
