GISS February global temperature down by 0.01°C from January.

The GISS V4 land/ocean temperature anomaly was 0.9°C in February 2022, down from 0.91°C in January. This small drop is very similar to the 0.017°C decrease (now 0.022°C) reported for TempLS.

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

February global surface TempLS down 0.017°C from January.

The TempLS mesh anomaly (1961-90 base) was 0.704°C in February, down from 0.721°C in January. That makes it the seventh warmest February in the record. The NCEP/NCAR reanalysis base index fell by 0.025°C.

The most prominent feature is the cold in N America and China, and the warmth almost everywhere else in Eurasia. The Eastern Sahara and Australia were also cool.

Here is the temperature map, using the LOESS-based map of anomalies.

GISS January global temperature up by 0.07°C from December.

The GISS V4 land/ocean temperature anomaly was 0.93°C in January 2022, up from 0.86°C in December. This rise is similar to the 0.08°C increase (now 0.068°C) reported for TempLS.

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

January global surface TempLS up 0.08°C from December.

The TempLS mesh anomaly (1961-90 base) was 0.724°C in January, up from 0.644°C in December. That makes it the fifth warmest January in the record. The NCEP/NCAR reanalysis base index fell by 0.06°C.

The most prominent feature is the cold in NE N America, and the warmth almost everywhere in Eurasia. In fact most of the land area was warm, except for the Sahara and Antarctica.

You may notice that Moyhu had another hiatus in December/January, which caused me to miss the annual summary. I won't try to catch up there at this stage. There may be other gaps during the year, but Moyhu will return.

GISS October global temperature up by 0.07°C from September.

The GISS V4 land/ocean temperature anomaly was 0.99°C in October 2021, up from 0.92°C in September. This rise is less than the 0.114°C increase (now 0.13°C) reported for TempLS.

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

October global surface TempLS up 0.114°C from September.

The TempLS mesh anomaly (1961-90 base) was 0.903°C in October, up from 0.789°C in September. It was the second warmest October in the record, just ahead of 2019 and just behind 2015. Either of those rankings could change with further data. The NCEP/NCAR reanalysis base index rose by 0.064°C.

The most prominent feature is the warmth in N Canada and adjacent Arctic.
There was a cool band from Central Europe through to central Asia, and Antarctica and W USA were also also cool.

NCEP/NCAR global temperature index up 0.064°C in October

I no longer post regular reports on my NCEP/NCAR reanalysis index, but since Moyhu is in catch up mode, it seems a good time to note the significant rise that has happened in the three months that I have been away:



This is more marked than what is shown by the surface measures, and makes October comparable with the warm months of 2020.

I should also note that, possibly since Feb 2020 (leap year), there has been an error in the dating of my published results here; the dates shown were a day behind. The fault sometimes became obvious as when July 1 became June 31. Anyway I think it is fixed now.
