The global average temperature anomaly for August 2022 was 0.93C which is a slight rise of 0.07C from July. The annual temperature anomaly for the first 8 months remains unchanged at 0.85C using a standard 1961-1990 baseline. So 2022 looks set to be cooler than 2016, 2019 and 2020.
La Nina is still dominating the southern pacific.
The full temperature data back to 1850 is available here.
Gut feel: Your global triangulation method should be used by all. However, I’m not sure what the results mean.
I think it is the most natural way to perform a spatial average. Each station contributes individually. An alternative 3D method is to use Icosahedral binning see – https://clivebest.com/blog/?p=8119
Some are commenting on similarities between the current prolonged La Niña and a comparable event in the early 1950’s, which preceded a period of global cooling. Is this comparison meaningful? Thanks
