The United Nations has warned that the current El Niño event could be the most intense ever recorded, with sea surface temperatures in the Pacific potentially exceeding historical scales by late 2026. This "Super El Niño" is triggering a cascade of extreme weather events across multiple continents, ranging from torrential rains and flooding in South America to severe droughts in Central America and rising temperatures globally.
In Argentina, provinces like Corrientes, Misiones, and Neuquén are experiencing significant disruptions. Neuquén’s governor announced a six-month meteorological emergency due to unprecedented rainfall, while Cordoba experts predict above-normal precipitation. The phenomenon is also causing logistical and health challenges; in Peru, food prices for fish and citrus have surged due to supply chain issues, and dengue deaths have risen sharply. Meanwhile, in Venezuela, the event brings hotter, drier conditions, contrasting with the wet extremes elsewhere.
Health and social impacts are widespread. In Mexico, UNICEF reports that extreme weather reduces primary school enrollment, particularly among girls. In Colombia and Peru, heatwaves and humidity increase risks of dehydration and vector-borne diseases. Scientists warn that coral reefs face existential threats, with up to 50% of species potentially at high risk of extinction if bleaching accelerates.
Governments are responding with coordinated measures. Paraguay established a National Emergency Table, while Ecuador hosts a biodiversity summit to discuss water security. Australian researchers recently identified new methods to predict ENSO cycles up to a year in advance, offering hope for better preparedness against future shocks.
