UN warns to prepare for potentially strongest El Niño yet, fearing climate change impacts

The United Nations and the World Meteorological Organization (WMO) have issued a recent warning to prepare for the imminent return of El Niño, with an 80% probability of its development between June and August 2026, and a 90% likelihood of it persisting until November. Most forecast models suggest this upcoming event will be at least moderate, and potentially strong, although there remains some uncertainty regarding its peak intensity.

This natural climate phenomenon is expected to heighten global temperatures and exacerbate extreme weather conditions, including severe droughts, heavy rainfall, and intense heatwaves across various regions. UN Secretary-General António Guterres emphasized that while climate change may not directly increase El Niño's frequency or intensity, a warmer planet will amplify its effects, declaring that "El Niño conditions will pour fuel on the fire of a warming world."

The warning follows the 2023-2024 El Niño, which was among the strongest on record and contributed to 2024 being the hottest year globally. In response, the UN is urging nations to enhance early warning systems, transition to renewable energy sources, and safeguard vulnerable communities to mitigate the widespread humanitarian and economic impacts.
