World temperature records were shattered on Sunday on what may be the hottest day scientists have ever logged, data suggests.
Inflamed by the carbon pollution spewed from burning fossils and farming livestock, the average surface air temperature hit 17.09C (62.76F) on Sunday, according to preliminary data from the Copernicus Climate Change Service, which holds data that stretches back to 1940. The reading inched above the previous record of 17.08C (62.74F) set on 6 July last year, but the scientists cautioned that the difference was not statistically distinguishable.
“What is truly staggering is how large the difference is between the temperature of the last 13 months and the previous temperature records,” said the Copernicus director, Carlo Buontempo. “We are now in truly uncharted territory – and as the climate keeps warming, we are bound to see new records being broken in future months and years.”
The finding comes as large parts of the world roast in punishing heat. Hot weather fuels crackling wildfires that burn homes to a crisp, and triggers silent waves of mass mortality that spill through hospital wards and retirement homes.
