August was the joint-hottest month on record, as human-driven climate change and a strengthening El Niño combined to raise temperatures across the planet.
Dr Samantha Burgess, strategic lead for climate at the Copernicus Climate Change Service, called it “a remarkable month in the global climate record”. The consequences, she said, were increasingly affecting communities, economies and ecosystems worldwide. The thermometer, once again, declined to offer comforting news.
Why did August become so hot?
Copernicus pointed to a potent combination of unusually high air temperatures and record ocean heat. Europe’s exceptional summer added to the evidence that climate change is intensifying extremes in both major parts of the climate system.
“The combination of record air temperatures, record ocean heat and Europe’s exceptional summer” showed that climate change was driving extremes across “both the atmosphere and the oceans”, Burgess said.
United Nations climate chief Simon Stiell said the record made humanity’s role unmistakable.
