The worldwide temperature numbers for September are in, and they don’t seem to be good. “This month was, in my skilled opinion as a local weather scientist—completely gobsmackingly bananas,” Zeke Hausfather posted Tuesday on X (previously often called Twitter).
Kristina Dahl, principal local weather scientist on the Union of Involved Scientists, learn that put up yesterday. “I have been sitting at my desk attempting to think about a greater technique to describe that, however I can not,” Dahl says. “It is simply stunning.”
“Regarding, worrying, wild—no matter superlative you need to use,” says Kate Marvel, senior scientist at Venture Drawdown, a nonprofit that fights local weather change. “That is what it’s.”
The graph under, created by Hausfather, a researcher on the local weather group Berkeley Earth, reveals temperature anomalies, that means how excessive every month was above a historic common baseline temperature. Every multicolored line represents a earlier 12 months, colour coded by decade. (The Nineteen Nineties, for instance, are the strains in yellow.) The stable black line is 2023, and it has been hovering above the others since Could. It stops within the month of September, which beat the prior month-to-month report by greater than 0.5 levels Celsius.
This September was on common 1.8 levels C hotter than preindustrial ranges, effectively above the Paris Settlement’s purpose of holding temperatures from rising greater than 1.5 C. (Essential caveats on that in a second.)

“We have already seen a summer time of utmost temperatures, so my threshold for being stunned was a bit increased,” Hausfather tells WIRED. “However simply how excessive September was, it is form of bananas; 0.5 C is simply off the charts. We’ve by no means seen a month with that stage of bounce earlier than.”
“It is astounding to see the earlier report damaged by a lot,” agrees Dahl. “And astounding to see that the worldwide temperature this September is on par with what we usually see in July—the most popular month of the 12 months, sometimes. So it actually simply illustrates how profoundly our local weather is shifting.”
What’s unfolded all summer time has been a combination of local weather science elements, a few of that are effectively understood and others which are extra unsure. It’s a certainty that the extra greenhouse gases we pump into the ambiance, the extra warming we get. “We must always anticipate not simply record-breaking extremes, however record-shattering extremes,” says Marvel. “Issues that break earlier data by unimaginable margins.”
