The main purpose of this ongoing blog will be to track planetary extreme, or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉
Main Topic: Earth Has Its Hottest Summer on Record
Dear Diary. It’s early September so climatologists are busy assessing how hot the summer was globally and nationally. During 2023 we say the hottest summer (and winter if you live in the Southern Hemisphere) on record. Apparently looking at Copernicus data, 2024 now tops 2023, which should be alarming for everyone, not just us climate people.
Here are more details from Seth Borenstein writing for the Associated Press (for a video and chart that I did not repost, click the following link):
Earth breaks yet another record for hottest summer | AP News
Hottest summer on record could lead to the warmest year ever measured
By SETH BORENSTEIN Updated 8:15 AM EDT, September 6, 2024
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 dialing 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.
This summer was the hottest on record
The northern meteorological summer — June, July and August — averaged 16.8 degrees Celsius, 0.03 degrees Celsius warmer than the old record in 2023.
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 said.
“What those sober numbers indicate is how the climate crisis is tightening its grip on us,” said Stefan Rahmstorf, a climate scientist at the Potsdam Institute for Climate Research, who wasn’t part of the research.
It’s a sweaty grip because with the high temperatures, the dew point — one of several ways to measure the air’s humidity — probably was at or near record high this summer for much of the world, Buontempo said.

Until last month Buontempo, like some other climate scientists, was on the fence over whether 2024 would smash the hottest year record set last year, mostly because August 2023 was so enormously hotter than average. But then this August 2024 matched 2023, making Buontempo “pretty certain” that this year will end up hottest on record.
