This summer's record-breaking heat has extended to September. A new report from the National Oceanic and Atmospheric Administration, or NOAA, found that September 2023 was the hottest in its 174 years of climate records.

The striking thing was just how abnormally hot September was, says Ellen Bartow-Gillies, a NOAA climatologist and the lead author of the report.

"This was the warmest September on record, but it also beat out the previous record September, which was in 2020, by 0.46 degrees Celsius, or 0.83 degrees Fahrenheit," Bartow-Gillies says. "A pretty significant jump."

She said another way to think about it is that compared to the average July from 2001-2010, "September 2023 was actually warmer than that."
