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

The GISS V4 land/ocean temperature anomaly was 0.80°C in December 2022, up from 0.73°C in November. This rise is very little more than the 0.065°C rise reported for TempLS.

Apologies for being a little late this month - I have been away from my computer.

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

December global surface TempLS up 0.065°C from November.

The TempLS FEM anomaly (1961-90 base) was 0.643°C in December, up from 0.578°C in November. This was only a partial recovery from the steep dro to November. The NCEP/NCAR reanalysis base index rose likewise by 0.105°C.

Continental Europe and N Africa were warm, as was Eastren N America. But there was a large cold region in the W of N America, especially Canada. Cold in central Asia, but warm in much of the Arctic..

Apologies for the lateness of this month's report; I have been away from my computer. But the scripts kept going, on the results page here.

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

As always, the 3D globe map gives better detail. There are more graphs and a station map in the ongoing report which is updated daily.
