The most powerful El Nino in a century could be on its way

A powerful El Nino event may develop in 2026, with forecasters warning it could become one of the strongest on record, potentially reshaping global weather patterns. The World Meteorological Organization (WMO) expects El Nino conditions to emerge soon and persist through winter, leading to extreme droughts in Central America, Asia, Africa, and Australia, while South America’s Pacific coast faces torrential rains and flooding. Paul Roundy, a professor of atmospheric and environmental sciences at the State University of New York at Albany, called this a "real potential for the strongest El Nino event in 140 years." The phenomenon occurs when trade winds weaken over the tropical Pacific, allowing warm water to accumulate—an area roughly the size of the United States—and disrupting atmospheric patterns worldwide. In Honduras, authorities estimate 75 municipalities could face severe drought, with Tegucigalpa already declaring a water emergency. El Nino’s impacts extend beyond drought, including increased wildfire risks in Australia, Canada, the U.S., and the Amazon rainforest due to heat and drought conditions. Economic losses from crop failures during past events, like the 2015-2016 El Nino, have reached trillions, leaving millions needing food assistance. The Atlantic hurricane season may also see reduced activity, as El Nino typically increases wind shear, suppressing storm formation. United Nations Secretary-General Antonio Guterres urged treating the event as an urgent climate warning, stating it will worsen global warming effects. Scientists emphasize El Nino’s role as a 'first atmospheric domino,' triggering cascading climate disruptions across continents.
