The World Meteorological Organization (WMO) has issued an urgent global warning regarding an exceptionally strong El Niño event that is expected to persist through early 2027. Driven by unprecedented ocean warming in the Pacific, the UN climate agency warns the phenomenon could intensify into one of the most powerful on record, heightening the risk of extreme heatwaves, catastrophic flooding, and prolonged droughts worldwide. UN officials are urging disaster management and humanitarian authorities to prepare immediately for widespread disruptions to agriculture, energy, and local economies.
