The UN’s World Meteorological Organization (WMO) has declared the arrival of a climate-heating El Niño event, with officials warning that preparation for extreme weather events is vital to save lives and livelihoods.
According to available reports, the last major El Niño was in 2016 and it remains the hottest year on record. But the new El Niño comes on top of the increasing global heating driven by human-caused carbon emissions, an effect the WMO called a “double whammy”. This can supercharge extreme weather, and temperature records are already being broken on land and at sea across the globe.
The WMO was quoted as saying that there was now a 90% probability of the El Niño event continuing to the end of 2023 at a moderate strength or higher. The chance of a strong and even hotter El Niño at the year’s end was put at 56% by US authorities in an estimate in early June.
Natural variations in winds and ocean temperatures in the Pacific drive the irregular switches between El Niño-which is known to be It is the planet’s biggest natural climate phenomenon and affects billions of people- and its cooler opposite La Niña.

According to reports, El Niño usually brings more flooding in the south of the US, the south of South America, the Horn of Africa and central Asia, while severe heatwaves and droughts often strike eastern Australia, Indonesia, south Asia and Central America.
“The onset of El Niño will greatly increase the likelihood of breaking temperature records and triggering more extreme heat in many parts of the world and in the ocean,” said Petteri Taalas, the WMO secretary-general. “The declaration by WMO is the signal to governments around the world to mobilise preparations. Early warnings and anticipatory action of extreme weather events associated with this major climate phenomenon are vital to save lives and livelihoods.”
Record temperatures have been recorded in recent months. For instance, In the UK the average temperature record for June was beaten by nearly a degree and an unprecedented heatwave hit the country’s seas. Sea ice around Antarctica has also hit a record low.
