The global temperature estimates made by the ECMWFECMWF The European Centre for Medium-Range Weather Forecasts is an independent intergovernmental organisation supported by most of the nations of Europe. It is based at three sites: Shinfield Park, Reading, United Kingdom; Bologna, Italy; and Bonn, Germany. It operates one of the largest supercomputer complexes in Europe and the world's largest archive of numerical weather prediction data. in the ERA5ERA ERA stands for 'ECMWF Re-Analysis' and refers to a series of research projects at ECMWF which produced various datasets (ERA-Interim, ERA-40, etcetera). series show that October 2024 was the second warmest in the short series back to 1948. I’m quite glad about that, because my DIYDIY Do It Yourself reanalysis series which I maintain showed the same thing. What is more astounding about October’s temperatures though, is that a 30 year linear trend on the ERA5 data shows a whopping 0.313°C decadal rise in global temperatures. If this were typical for all months of the year you can forget about limiting the increase in warming to only 1.5°C, it would be more like 3°C.😮
