GENEVA: Earth has sweltered through its hottest Northern Hemisphere summer ever measured, with a record warm August capping a season of brutal and deadly temperatures, the World Meteorological Organisation has stated.
Last month was not only the hottest August scientists ever recorded by far with modern equipment, it was also the second hottest month measured, behind only July 2023, WMO and the European climate service Copernicus announced on Wednesday.
August was about 1.5 degrees Celsius (2.7 degrees Fahrenheit) warmer than pre-industrial averages. That is the threshold that the world is trying not to pass, though scientists are more concerned about rises in temperatures over decades, not merely a blip over a month’s time.
The world’s oceans — more than 70 per cent of the Earth’s surface — were the hottest ever recorded, nearly 21 degrees Celsius (69.8 degrees Fahrenheit), and have set high temperature marks for three consecutive months, the WMO and Copernicus said.
“The dog days of summer are not just barking, they are biting,” United Nations Secretary-General Antonio Guterres said. “Climate breakdown has begun.”
So far, 2023 is the second hottest year on record, behind 2016, said Copernicus.
Scientists blame ever warming human-caused climate change from the burning of coal, oil and natural gas with an extra push from a natural El Nino, which is a temporary warming of parts of the Pacific Ocean that changes weather worldwide.
Usually an El Nino, which started earlier this year, adds extra heat to global temperatures but more so in its second year.
Climatologist Andrew Weaver said the WMO numbers and Copernicus come as no surprise, bemoaning how governments have not appeared to take global warming issue seriously enough.
“It’s time for global leaders to start telling the truth,” said Weaver, a professor at the School of Earth and Ocean Sciences at the University of Victoria in Canada. “It’s all hands on deck now to prevent 3.0 C global warming that will wreak havoc worldwide.”
