El Niño has begun and is likely the strongest on record, pushing 2027 toward the hottest year in modern history. Met Office and NOAA warn of extreme weather worldwide, with the UK facing a wetter autumn and drought risks elsewhere. The phenomenon interacts with human-caused climate change to amplify heat and disruption.
El Niño has formed in the Pacific and is expected to strengthen through late 2026, with a 63% chance of reaching a very strong level. Forecasts warn of hotter global temperatures and extreme weather, while impacts will vary by region. Scientists urge preparation and climate action as nations monitor evolving conditions.
