GISS October global temperature down by 0.13°C from September.

The GISS V4 land/ocean temperature anomaly was 1.34°C in October 2023, down from 1.47°C in September. This fall is similar to the 0.1°C fall reported for TempLS.

As with TempLS, October was by a large margin the warmest October in the record - next was 1.02°C in 2016. It was nearly the second warmest month of all kinds; just pipped by Feb/Mar of 2016.

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

October global surface TempLS down 0.102°C from September.,still second warmest month.

The TempLS FEM anomaly (1961-90 base) was 1.182°C in October, down from 1.284°C in September. It was still the warmest October in the record by 0.26°C well ahead of 0924°C in 2015, and it wass till, after September, the warmest month of any kind. The NCEP/NCAR reanalysis base index fell by 0.069°C.

The average for 2023 to date is 0.966°C, well ahead of 2016 at 0,855°C. I'll show again the table of months in descending order of warmth:





Here is the corresponding stacked graph, showing how much hotter recent months have been

Most of the world was warm, with the only cool spots being Scandinavia and areas of Antarctica. Very warm in central Siberia.

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.
