El Niño set to be 'strongest in living memory,' scientists warn of 'unprecedented event'

The UK Met Office has issued a stark warning that the developing El Niño weather pattern is anticipated to be the strongest in living memory, with predictions suggesting it could be the most significant such event since the 19th century. Forecasters indicate that sea surface temperatures in the equatorial Pacific are projected to rise by more than 3°C, a level described as "unprecedented" in modern climate records.

Scientists at the Met Office have stated that they have never observed an El Niño signal of such intensity in their forecasts, emphasizing the potential for widespread global climate impacts. This powerful natural phenomenon is expected to drive up global temperatures, making 2027 "very likely" to surpass 2024 as the warmest year on record, especially when combined with ongoing human-induced climate change.

The effects of this intense El Niño are projected to include a heightened risk of drought in tropical regions, southern Africa, and northeast Australia. Conversely, northwestern Europe, including the UK, is warned to expect a wetter and stormier autumn and early winter due to the changing weather patterns.
