Record-Breaking El Niño Expected to Unleash Extreme Weather
A super El Niño is developing in the tropical Pacific, with a 90% likelihood of becoming the strongest in 150 years, according to Berkeley Earth (New Scientist, 2026-07-23). Forecast models predict sea surface temperature anomalies peaking at 3.6°C (6.5°F) above average, surpassing the 2015-16 record of 2.75°C (4.95°F). This event is progressing faster than any previous El Niño, with central-eastern Pacific temperatures already 2.1°C (3.78°F) above average. The phenomenon, which peaks in late autumn or winter, is expected to drive global temperatures to unprecedented levels, potentially exceeding 1.7°C (3.06°F) above pre-industrial averages in 2027. The event is also likely to exacerbate extreme weather patterns worldwide, including droughts, floods, and wildfires.
