The Day After Tomorrow (2004)

As Paleoclimatologist Jack Hall is in Antartica, he discovers that a huge ice sheet has sheared off. But what he does not know is that this event will trigger a massive climate shift that will affect the world population. Meanwhile, his son Sam is with friends in New York City to attend an event. There, they discover that it has been raining non-stop for the past three days, and after a series of weather-related disasters begin to occur all over the world, everybody realizes the world is about to enter a new Ice Age and the world population begins trying to evacuate to the warmer climates of the south. Jack makes a daring attempt to rescue his son and his friends who are stuck in New York City and who have managed to survive not only a massive wave but also freezing cold temperatures that could possibly kill them.—John Wiggins
