evidence: WASHINGTON (AP) — On Sunday, the Earth sizzled to the hottest day ever measured by humans, yet another heat record shattered in the past couple of years, according to the European climate service Copernicus Tuesday. Copernicus’ preliminary data shows that the global average temperature Sunday was 17.09 degrees Celsius (62.76 degrees Fahrenheit), beating the record set just last year on July 6, 2023 by .01 degrees Celsius (.02 degrees Fahrenheit). Both Sunday’s mark and last year’s record obliterate the previous record of 16.8 degrees Celsius (62.24 degrees Fahrenheit), which itself was only a few years old, set in 2016. Without human-caused climate change, records would be broken nowhere near as frequently, and new cold records would be set as often as hot ones.

"We are now in truly uncharted territory and as the climate keeps warming, we are bound to see new records being broken in future months and years."
