The theme of the book(film)'The day after tomorrow'?

The Day After Tomorrow is a 2004 apocalyptic science-fiction film that depicts catastrophic effects of global warming and boasts high-end special effects, bending the lines between science, reality and science fiction. Worldwide, it is the 38th top grossing film of all time, with total revenue of US$542,771,772. It is the second highest grossing movie not to be #1 in the US box office (behind My Big Fat Greek Wedding). Currently holds the record for biggest opening weekend gross for any movie not opening at #1 with $68.7 million. The movie was filmed mostly in Montreal, and, as of 2007, is the highest grossing Hollywood film in history to be filmed in Canada.

The Day After Tomorrow premiered in Mexico City on May 17, 2004 and was released worldwide from May 26 to May 28 except in South Korea and Japan where it was released June 4 and June 5, respectively. (It was originally planned for release in summer 2003.)

Background:
The movie was inspired by The Coming Global Superstorm, a book written by Art Bell & Whitley Strieber. (Strieber also wrote the film's novelization). The pair used to co-host a paranormal themed talk show. Bell appeared on the show throughout the week on his Art Bell Show (now Coast to Coast AM) while Strieber hosted the weekend segment of the show entitled Dreamland. On both shows, the co-authors/paranormal talk show hosts would delve into such topics with guesses as what life would be like after humans have depleted all of their natural resources and destroyed their environment. There are relatively subtle connections between the book and the film: one being that there is a scene depicting a rescue mission at the New York Public Library.

Shortly before and during the release of the movie, members of environmental groups and former Vice President Al Gore distributed pamphlets to moviegoers describing what they believe to be the possible effects of global warming. Although the film depicts some effects of global warming predicted by scientists, like rising sea levels, more destructive storms, and disruption of ocean currents and weather patterns, it depicts these events happening much more rapidly and severely than predicted by most scientists, and the theory that a "superstorm" will create rapid worldwide climate change is not widely accepted. When the film was playing in theaters, much criticism was directed at politicians concerning the Kyoto Protocol and climate change, and in the end the movie created quite a political stir.
