GISS May global temperature down by 0.06°C from April.

The GISS V4 land/ocean temperature anomaly was 0.94°C in May 2023, down from 1.00°C in April. This fall is a little more than the 0.028°C fall reported for TempLS.

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

May global surface TempLS down 0.028°C from April.

The TempLS FEM anomaly (1961-90 base) was 0.829°C in May, down from 0.857°C in April. It was still the second warmest May in the record. The NCEP/NCAR reanalysis base index rose by 0.014°C. Both changes were very small

Almost all the world was warm, with a cold spot in India, north into central Asia, and also somewhat in Australia. Most of Canada was very warm. The Pacific W of Peru is starting to warm.

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.
