In Independence Day (1996), Roland Emmerich envisioned aliens to be mankind’s number-one enemy; in The Day After Tomorrow the director identified a much more realistic and terrifying enemy on Earth: the forces of Nature rebel against the senseless acts of man, provoking apocalyptic scenarios. Critics defined The Day After Tomorrow the first eco-catastrophic film. In the movie, temperatures at the Earth’s poles drastically increase in a matter of hours, causing glaciers to melt and an enormous mass of fresh water to flow into the ocean which alters the fragile system of sea currents that regulates the Earth’s climate. Temperatures in New York plummet, thick hailstorms devastate Tokyo and tornadoes sweep across Europe; the entire world is overturned by this global catastrophe. In just a few hours of this Apocalyptic disaster, meteorologist Jack Hall of NOOA witnesses climatic changes that he had not foreseen happening for hundreds of years. Hall sounds the alarm but it is too late. There is nothing left to do but attempt to save millions of people, including his son, who is trapped in the library of an ice-gripped New York. Initially hostile to this film, American scientists eventually supported it, convinced that pictures would have a much greater effect on the general public than written words. Climatologist Dan Scharg admitted that the movie disconcerted him. “It is so apocalyptic,” he stated “that you fear people might lose faith in science. On second thought, however, it will shake them from their apathy.” Environmentalists shared his opinion. Their view can be summed thus: “A film destroys the Earth. In this way, we save it!” An interesting note about The Day After Tomorrow: in March 2002, the Larsen B ice shelf in Antarctica plunged into the ocean, just a few weeks after the director had imagined a similar incident for the opening scene of his movie.
