El Niño is a weather pattern that recurs every two to seven years, and the 1997-98 event alone killed an estimated 24,000 people and caused $34 billion in economic damage worldwide. This film explains the ocean-atmosphere mechanics behind the phenomenon and tracks its damage across continents: hurricanes battering Mexico, floods in California running up half a billion dollars in losses, and Indonesia's worst drought on record. It follows the flooding that swept through Peru, the drought that gripped parts of Africa, and the unusually torrential rain that hit the UK in 2015 and 2016, using footage of the disasters alongside expert interviews to connect a single climate pattern to consequences on opposite sides of the planet. The documentary treats El Niño less as a single storm than as a global trigger, showing how a shift in Pacific Ocean temperatures can rewrite rainfall and drought patterns from South America to Southeast Asia within the same year, and asks what future cycles might still have in store.
