"The Day After Tomorrow"

Credibility rating: 2

As nice as it is to encounter a blockbuster-sized movie dealing overtly with global warming, it would be nicer still if that film was directed by someone other than Roland Emmerich, the mayhem maven behind “10,000 B.C.,” “Godzilla” and “Independence Day.” Emmerich speeds up cataclysmic events leading to a second Ice Age that would occur at a more gradual rate in reality, in the interest of delivering spectacular CGI money shots of tornadoes decimating the Hollywood sign and an icicle-covered New York. It’s about as believable as aliens blowing up the White House.
