Sweltering temperatures mean Earth breaks yet another record for hottest summer

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 reports.

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 dialing up temperatures and extreme weather, scientists say.

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.

The Augusts of both 2024 and 2023 tied for the hottest Augusts globally at 16.82 degrees Celsius (62.27 degrees Fahrenheit).

July was the first time in more than a year that the world did not set a record, a tad behind 2023, but because June 2024 was so much hotter than June 2023, this summer as a whole was the hottest, Copernicus Director Carlo Buontempo says.
