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.
