Climate science from the climate scientists at NOAA:
The Decmeber global surface temperature was 1.43°C (2.57°F) above the 20th-century average of 12.2°C (54.0°F), making it the warmest December on record. This was 0.30°C (0.54°F) above the previous record from December 2015. December 2023 marked the 48th-consecutive December and the 538th-consecutive month with temperatures at least nominally above the 20th-century average.
And of course, the chart:
