Global heating

I recently came across an interesting graph on Carbon Brief (here). It shows the frequency of all-time hot records (dashed red line) and cold records (dashed blue line) over global land regions shown as a nine-year running average over 1950-2024, as represented by the Copernicus/ECMWF ERA5 surface temperature reanalysis. This is contrasted with the theoretical probability of new records expected in a stationary climate as the temperature measurement series expands (solid black line).

The graph shows a clear warming trend for global land masses.
