https://en.wikipedia.org/wiki/The_Day_After_TomorrowPaleoclimatologist Jack Hall and his colleagues, Frank and Jason, are drilling for ice-core samples on the Larsen Ice Shelf for NOAA when the shelf breaks apart. When Jack later presents his findings on global warming at a United Nations conference in New Delhi, he fails to convince diplomats or U.S. Vice President Raymond Becker. However, Professor Terry Rapson of the Hedland Climate Research Centre in Scotland believes in Jack's theories. Shortly after, several buoys in the North Atlantic simultaneously register a sharp drop in ocean temperature and Rapson concludes that melting polar ice has begun to disrupt the North Atlantic Current. He contacts Jack, whose paleoclimatologic weather model demonstrates how climate changes caused the first ice age.
