El Niño Hits 2.0C Super Threshold as NOAA Sees 75% Odds of a Record Peak
3 articles · Updated · CNN · Sep 14
Summary
NOAA’s weekly Niño 3.4 RONI just reached 2.0 degrees Celsius above average, pushing El Niño into the unofficial “super” category and making it the strongest event ever recorded for this date.
That rapid rise since June has put the climate pattern on an unprecedented track, with NOAA saying it has a 75% chance of becoming the strongest El Niño since records began in 1950 by late 2026 or early winter.
The warming is already reshaping weather worldwide: the Atlantic has yet to produce a hurricane amid intense wind shear, while the eastern and central Pacific have generated 16 storms, including two Category 5 hurricanes.
Indonesia’s wildfires and this summer’s extreme global heat have also been linked to the event, whose effects are amplified by a hotter climate even after NOAA’s newer RONI metric adjusts for long-term ocean warming.
Winter is still expected to be El Niño’s peak influence period, setting up the phenomenon to play a major role in U.S. winter weather and potentially extend record global warmth into 2027.
With a rare 'super' El Niño rewriting climate records, which regions will face unprecedented winter extremes in 2026?
How will NOAA's new climate-adjusted tracking system fundamentally change our preparation for this rapidly intensifying weather phenomenon?
Could interacting climate anomalies trigger unforeseen global disasters that even the most advanced forecasting models missed this year?
The 2026–2027 Super El Niño: Record-Breaking Climate Disruption, Global Risks, and Adaptation in a Warming World
Overview
The 2026 Super El Niño began when easterly trade winds weakened and reversed, causing warm water to build up in the western Pacific and trigger powerful Kelvin waves. These waves traveled east, deepening the warm surface layer and suppressing cold-water upwelling near South America, which rapidly intensified the warming trend. As a result, massive thermal energy was released into the atmosphere, making August 2026 the hottest month ever recorded. This extreme event disrupted global weather, fueled marine heatwaves, and led to severe droughts, floods, and economic shocks, including energy crises and record-high food prices, highlighting the urgent need for anticipatory action and adaptation.
