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:

November global surface TempLS same as October, second warmest November in record.

The TempLS FEM anomaly (1961-90 base) was 1.157ºC in November, effectively same as 1.158ºC in October. The difference is small enough that it is about 50% likely to be reversed with late data.

November 2023 at 1.269ºC was the warmest November in the record; after 2024, next was 2015 at 0.927ºC. It looks as if 2024 will break the annual record (2023) by about 0.12ºC.

For about 13 years, I have posted a follow-up to these regular posts, in which I compare the monthly value and map with GISS. They general result is that they match very well, so I have decided to not keep doing that. I think the point is made. So this will be the only TempLS post for the month. All the data for comparison is available at the latest data page.

GISS October global temperature up by 0.09°C from September.

The GISS V4 land/ocean temperature anomaly was 1.32°C in October, up from 1.23°C in September. This rise was a little more than the 0.05°C rise reported here for TempLS.

October 2024 fell just short of the 2023 record (1.34°C) - next was 1.08°C in 2015.

As usual here, I will compare the GISS and earlier TempLS plots below the jump.

October global surface TempLS up 0.05°C from September,.

The TempLS FEM anomaly (1961-90 base) was 1.133°C in October, up from 1.083°C in September. It was not quite as warm as Oct 2023, but well clear of any earlier October (2015 0.922°C)

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


The main thing to note now is that Oct was close to the 2024 YTD average, making it even more certain that 2024 will be a record year.

GISS September global temperature down by 0.04°C from August.

The GISS V4 land/ocean temperature anomaly was 1.26°C in September, down from 1.3°C in August. This drop was similar to the 0.071°C fall reported here for TempLS.

As with TempLS, September broke a sequence of fifteen record months- September 2023 was 1.48°C, but next was 2020 at 0.96°C.

As usual here, I will compare the GISS and earlier TempLS plots below the jump.

September global surface TempLS down 0.071°C from August.

The TempLS FEM anomaly (1961-90 base) was 1.094°C in September, down from 1.165°C in August. It was a record in a way - it is the first month of the last 16 that was not a record warm. September 2023 was 1.21°C; however last month was warmer than any September before 2023.

This month's posting has been delayed by the late posting of results from NOAA, which was affected by the floods in Asheville.
