El Niño planet-warming weather phase has begun

A natural weather event known as El Niño has begun in the Pacific Ocean, likely adding heat to a planet already warming under climate change. US scientists confirmed that El Niño had started. Experts say it will likely make 2024 the world’s hottest year. They fear it will help push the world past a key 1.5C warming milestone.

It will also affect world weather, potentially bringing drought to Australia, more rain to the southern US, and weakening India’s monsoon.

The event will likely last until next spring, after which its impacts will recede.

For months, researchers have been increasingly confident that an El Niño event was set to emerge in the Pacific Ocean. 

“It’s ramping up now, there have been signs in our predictions for several months, but it’s really looking like i...

The World Meteorological Organization says there’s a 75-80% chance of a weak El Niño forming within three months. The naturally occurring event causes changes in the temperature of the Pacific Ocean and has a major influence on weather patterns around the world. It is linked to floods in South America and droughts in Africa and Asia.

El Niño events often lead to record temperatures as heat rises from the Pacific.

According to the WMO update, sea surface temperatures in the east-central tropical Pacific have been at weak El Niño levels since October. However the atmosphere has not yet responded to the extra warmth that’s produced by the upwelling seas.

Scientists have been predicting the likelihood of a new event since May this year, with confidence increasing.

The Australian Bureau of...
