This movie is watching just for the first half of it. It is about a catastrophic chain of weather events caused by global warming that plunges the Earth into another ice-age. There are hail storms in Tokyo, blizzards in New Delhi, twisters in Los Angeles, and a massive tidal wave in New York city. The only downside to the movie was a lack of character development. Other than that, I'd say rent or even buy this movie on DVD or video.
