"World Meteorological Organization warns of record temperatures and extreme heat in environmental ‘double whammy’."
"The arrival of a climate-heating El Niño event has been declared by the UN’s World Meteorological Organization (WMO), with officials warning that preparation for extreme weather events is vital to save lives and livelihoods.
The last major El Niño was in 2016, which remains the hottest year on record. 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 said 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 and its cooler opposite La Niña. It is the planet’s biggest natural climate phenomenon and affects billions of people."
