What Can We Expect From El Niño? Scientists Say Brace for the Worst.
The World Meteorological Organization says the event could drive above-average temperatures and shift rainfall patterns worldwide.
September sea surface temperatures in the Niño3.4 Pacific region reached an all-time high of 29.70°C, the European Union's Copernicus Climate Change Service reported, while global average sea surface temperatures also hit a September record of 21.05°C.
El Niño is a natural climate cycle that warms tropical Pacific temperatures, typically recurring every two to seven years, and the current event is an 'exceptionally strong El Niño' that has not yet peaked, Copernicus stated.
On Friday, Japan's weather agency declared this El Niño the 'strongest intensity on record' with temperatures 4°C above normal, although Copernicus maintained it 'cannot yet say that the current El Niño is the strongest ever recorded.'
Widespread drought and flood risks are expected, the World Meteorological Organization warned, as the event shifts rainfall patterns, while the UN Development Programme warned of a 'perfect storm' potentially pushing millions into poverty.
Copernicus director Carlo Buontempo warned that the new run of months above 1.5°C is likely to last into 2027, and experts have warned this El Niño could push global temperatures to a new record in 2027.
