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).
