Urgent Warning: El Niño Has Begun and Could Trigger the Hottest Year Ever

El Niño has officially developed in the tropical Pacific, marking a major shift in the global climate system after months of warnings from forecasters. The announcement came from the US National Oceanic and Atmospheric Administration on June 11, 2026, as ocean and atmospheric measurements confirmed that the warming pattern was fully established.

The event is expected to strengthen considerably through late 2026, potentially disrupting rainfall, storms and temperatures across several continents. Scientists are particularly concerned about what happens when a powerful natural warming cycle develops on top of already elevated global temperatures.
