One of the Coolest Years for the Rest of Our Lives

NASA announces another record-breaking year.

Earth’s average surface temperature in 2023 was the warmest on record. Global temperatures last year were around 2.1 degrees Fahrenheit (1.2 degrees Celsius) above the average for NASA’s baseline period (1951-1980).

[This] was about 2.5 degrees Fahrenheit (or about 1.4 degrees Celsius) warmer in 2023 than the late 19th-century average, when modern record-keeping began.

The European climate agency Copernicus estimates that 2023 was 0.3 degrees Fahrenheit (0.17 degrees Celsius) above the previous record in 2016. 

Update (January 19):  Two views of the temperature anomalies (with different baselines):

Last year is exceptional--compared to the past.
