Super-Duper El Nino pushes ocean temperatures to a 76-year high

Earth is facing a powerful El Nino event as sea surface temperatures in the central and eastern Pacific Ocean have risen to 3.4 degrees Celsius above normal, marking the most dangerous such cycle recorded since 1950. Weather experts are calling it a super-duper El Nino, which is expected to peak in December and could persist until February 2027 with a nearly one hundred percent probability according to the World Meteorological Organization. Researchers at the Climate Impact Lab at the University of Chicago estimate that this severe weather pattern could cause about 451,000 extra deaths worldwide between June 2026 and February 2027 due to extreme heat and changing disease risks. India has also felt the impact as its 2001-onward fourth driest southwest monsoon ended with 13 percent less rainfall than usual. In Europe, countries like France, Spain, and Britain faced record heatwaves that sharply lowered water levels in major rivers such as the Danube, Rhine, and Thames. Weather meteorologist Ryan Mau noted that climate maps show the planet glowing almost entirely red, while climate scientist Zeke Hausfather described the event as entering uncharted territory with Nino 3.4 surface temperatures reaching historic highs.

Context

El Nino is the warm phase of a natural climate cycle called the El Nino-Southern Oscillation that occurs every two to seven years when Pacific winds weaken and push warm water eastward. Scientists warn that this natural warming pattern is now combining with human-driven climate change to worsen extreme weather risks like droughts and floods globally.
