El Niño has officially begun, and it is forecast to intensify into a very strong or “Super” El Niño with major shifts in global weather patterns and an even hotter climate, according to a new report released Thursday morning by the National Oceanic and Atmospheric Administration (NOAA).

New predictions from the European Centre for Medium-Range Weather Forecasts (ECMWF) indicate sea surface temperatures in the central equatorial Pacific Ocean will climb 5.47.2° F (3 degrees Celsius) above average by December 2026. The scariest predict a spike above 7.2° F (4 C).

El Niño is a periodic weather pattern in the tropical Pacific Ocean that alters winds and features unusually hot waters in the central and eastern Pacific. These changes in winds and ocean temperatures have knock-on effects on weather patterns worldwide.

NOAA’s Climate Prediction Center is giving this El Niño a 63% chance of becoming a “very strong” event (a Super El Niño) and one of the “largest El Niño events in the historical record. The Center is giving 100% odds of El Niño continuing through the fall and extremely high odds continuing into the winter.

WHAT WILL HAPPEN: Super El Niños transfer large amounts of heat from the ocean to the atmosphere, which is highly likely to mean another record setting year will follow in terms of global heat.

Effects to expect: Increase in heat waves | increased wildfire risk | greater stress on agriculture | extreme rainfall and flooding | increased drought especially in Australia, Indonesia, South Africa and rainforests | marine ecosystem disruption and extensive coral bleaching.
