January global surface TempLS up 0.073°C from December, warmest January in record.

The TempLS FEM anomaly (1961-90 base) was 1.159°C in January, up from 1.086°C in December. It was, by a small margin, the warmest January in the record, ahead of 1.115°C in 2024. This is a surprise - the previous record month was August 2024. January was also warmer than the record annual average (2024).

Here is the corresponding stacked graph, showing how much hotter recent months have been:

December global surface TempLS down 0.09°C from November, but record warm 2024.

The TempLS FEM anomaly (1961-90 base) was 1.062°C in December, down from 1.153°C in November. It was,the second warmest December, after 2023.

As long expected, 2024 was the warmest year in the record, at 1.134°C, with 2023 next at 1.018°C. Here is a graph of the progress of the annual records. The colors change when there was a new record, shown by a subsequent horizontal line:
