2026 El Niño could become most powerful in 150 years

Climate models suggest the developing 2026-27 El Niño could become the strongest in nearly 150 years. Drawing on 667 ensemble forecasts from 14 leading seasonal climate models, climate scientist Zeke Hausfather said the event is not only expected to surpass the historic 1997-98 and 2015-16 El Niño episodes, but could exceed them by a margin that has "never been observed".
