Earth sets new record for hottest summer, raising global heat concerns

Summer 2024 sweltered to Earth's hottest on record, making it even more likely that this year will end up as the warmest humanity has measured, European climate service Copernicus reported Friday.

And if this sounds familiar, that's because the records the globe shattered were set just last year as human-caused climate change, with a temporary boost from an El Nino, keeps dialling up temperatures and extreme weather, scientists said.

The northern meteorological summer June, July and August averaged 16.8 degrees Celsius (62.24 degrees Fahrenheit), according to Copernicus. That's 0.03 degrees Celsius (0.05 degrees Fahrenheit) warmer than the old record in 2023. Copernicus records go back to 1940, but American, British and Japanese records, which start in the mid-19th century, show the last decade has been the hottest since regular measurements were taken and likely in about 120,000 years, according to some scientists.
