El Niño 80% Likely, Extreme Weather

The World Meteorological Organization (WMO) has issued an urgent warning regarding an 80% probability of the El Niño phenomenon developing between June and August, with a 90% chance of it persisting until at least November. This natural climate pattern, characterized by warming sea surface temperatures in the central and eastern equatorial Pacific Ocean, is expected to significantly amplify global temperatures and rainfall patterns. UN Secretary-General António Guterres has called it an 'urgent climate warning,' emphasizing that El Niño conditions will 'pour fuel on the fire of a warming world,' exacerbating human-driven climate change. Forecasts indicate a nearly universal dominance of above-normal temperatures globally, increasing the risk of compounding hazards like severe heatwaves, prolonged agricultural droughts, and flash flooding. Regional impacts are predicted, including below-normal rainfall in the Horn of Africa and South Asia, and drier, warmer conditions in Central African Republic. Conversely, some regions like southern South America and parts of the United States may experience increased rainfall. The WMO and other climate agencies, including the European Centre for Medium-Range Weather Forecasts and the United States — National Oceanic and Atmospheric Administration, are closely monitoring the event, with some models suggesting it could be 'at least moderate and possibly strong,' potentially rivaling 'super El Niño' events of the past. Scientists warn that while climate change may not increase El Niño's frequency, it will intensify its associated impacts, making extreme weather events more severe and potentially leading to 2027 becoming the hottest year on record. The event is expected to have cascading impacts on global trade, economies, and human security, necessitating urgent climate action and preparedness in climate-sensitive sectors like agriculture, water management, energy, and health.
