Risks of historic El Niño persisting through spring 2027 rising, says NWS The National Weather Service warns that the chances of a historic El Niño event persisting through spring 2027 are increasing, with a staggering 97% probability.
This raises concerns about the already strained global climate. El Niño events can have devastating consequences, including severe droughts and record breaking heatwaves.
A "super El Niño" – one that drives sea surface temperatures at least 2C higher than average – would be catastrophic, amplifying the impacts of climate change and leading to new global heat records.
