Risks of historic El Niño persisting through spring 2027 rising, says NWS | US news
El Niño is getting stronger and risks of a historical event The power of extreme weather is increasing around the world, according to the latest analysis from the U.S. National Weather Service.
Models currently show an 81% chance of a very strong El Niño occurring, which would be among the largest El Niño events on Earth. Historical record dating back to 1950It will improve before the end of this year, forecasters said in an advisory report released Thursday. There is almost certainty (97% probability) that conditions will persist through spring 2027.
“The probabilities and magnitudes continue to increase,” climate scientist Daniel Swain said. in question In an on-air discussion Thursday, he explained that the observed conditions were already in record-breaking territory. “So far in calendar history, El Niño is as strong or stronger than what we have seen before, and that trend is expected to continue,” he added.
El Niño is a natural climate phenomenon characterized by warming sea surface temperatures in the central and eastern tropical Pacific Ocean and can create major atmospheric disruption. It alters jet streams and alters rainfall patterns, fueling more intense storms in some parts of the world and drying out others.
Each El Niño event is unique due to the significant variability between them, and many factors affect the weather. But climate scientists around the world are warning that a so-called “super El Niño” that raises sea surface temperatures by at least 2C (36F) above average could have tremendous power to wreak havoc and set the stage for record global heat. Its effects could be added to those already fueled by the climate crisis.
A super El Niño occurred in 2015 Severe drought in Ethiopia and water shortages in Puerto Rico set records after the start of a severe hurricane season in the north-central Pacific, according to an analysis by US federal scientists. The cycle tends to create drought and heat in Australia, around southern and central Africa, India, and parts of South America, including the Amazon rainforest. Meanwhile, heavy rains could hit the southern US, parts of the Middle East and south-central Asia.
Predictions that global temperatures are expected to rise even further next year come amid an already devastatingly hot spring and summer. Western Europe experienced its warmest June in history, with many countries breaking all-time records, according to the European Union’s Copernicus Climate Change Service (C3S).
“June 2026 highlighted how profoundly the climate has changed,” C3S deputy director Dr Samantha Burgess said in a statement. “The result is increasingly intense heatwaves, a persistently warm ocean, and increasing risks to people, ecosystems and infrastructure.”
more than that More than 3,700 deaths were recorded in France, the Netherlands and Belgium – probably an underestimated number. Twenty US states recorded temperatures above 100F (38C) during a punishing heat dome that marred Fourth of July celebrations last week. dozens of deaths and millions of emergency room visits.
A massive heat dome is also expected to expand into the western United States and central plains this week, threatening more sweltering conditions.
“On Sunday and Monday, we’re starting to see some eyebrow-raising temperatures,” Swain said, adding that temperature records could be broken in the interior west, with many states bracing for temperatures to exceed 100F. This may increase the risk of fire in the drought-affected area. As of Thursday, firefighters were battling 38 large fires across the country. More than 3.4 million acres (1.4 million hectares) have already burned in the United States this year.
