THIS year’s El Nino is on track to be the strongest on record, threatening to unleash extreme weather across the globe and make 2027 the hottest recorded year by far.
It is expected to be the most “intense” El Nino in more than a century, the head of longrange forecasting at the UK’s Met Office warned on Friday.
Stacked on top of long-term human-caused climate change, the temporary jolt will offer a glimpse of the heat the world can expect by the late 2030s, experts say. Here’s what to know. • What is El Nino? • El Nino is the warming phase of a natural cycle in the tropical Pacific known as the El Nino-Southern Oscillation (ENSO).
It sets in when trade winds that blow from east to west temporarily ease up, allowing warm water which normally piles up in the western Pacific Ocean to slide back east and rise to the surface.
When those warmer-than-average surface temperatures last for a few months, they cause more storms and clouds over the region, “which cause ripple effects through the entire global atmosphere”, explained Emily Becker, a climate scientist at the University of Miami.
