July 21 was the hottest day on record, European climate agency says
Preliminary data from Copernicus shows that the global average temperature Sunday was 17.09 C, beating the record set just last year on July 6, 2023 by 0.01 C. Both Sunday's mark and last year's record obliterate the previous record of 16.8 C, which itself was only a few years old, set in 2016.
