Global Temperature updated for July 2024
The global temperature anomaly for July was 1.27 deg.
C relative to a 1961-1990 baseline. These results use GCHN monthly land temperatures combined with HadSST4 ocean temperatures. I use a novel method to calculate this using a 3D spherical triangulation of the earth’s surface. This is shown below.
The monthly trends relative to the 1961-1990 baseline are shown below.
One of the problems with Global Warming is that the underlying temperature trends are superimposed on far larger but shorter natural variability cycles (El Nino).
Therefore it makes little sense to push for action based on just one month’s temperature. It may even take another decade to be certain that average temperatures really have exceeded 1.5 C.
A far better method to determine when this will happen is based on using Icosahedral grids with decadal averaging
The observed stable decadal trend shows that the Paris Agreement to limit warming to 1.5C since the preindustrial level will very likely be exceeded in 2032

What is the point of a decadal trend graph of global temperature, subtext supposed man-made global warming, when that graph includes natural events like El Ninos, which predominated over La Ninas in the 1980s and 90s due to reduced global cloud cover, and the verboten-to-mention massive Hunga Tonga undersea volcanic eruption which caused the 2023-24 spike (with a minor El Nino assist)?

1960 was probably the low point of a cooler period ending around the early 70s. It would be interesting to extend the graph back to 1930 or 1920. I’m always suspicious of these short term comparisons especially those beginning in 1960-1970.
