This is the conclusion of the Copernicus Climate Change Service (C3S). This reports the recorded variations in surface air temperature and sea ice coverage. They confirm that November 2023 was the warmest November on record worldwide. The average surface air temperature is 14.22°C.

Phenomena that come together

The average sea surface temperature for November 2023 was also the highest on record. That is, all records point to record temperatures. As if that were not enough, the El Niño phenomenon continued in the equatorial Pacific. These anomalies converge with all the other factors studied.
