My DIYDIY Do It Yourself global temperature series was wrong once again in April. It predicted a tie in global temperatures with April 2016, but shock horror, 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). reports an anomaly of +0.67°C, which is well above the +0.529°C of 2016 making it the eleventh consecutive warmest month. 😲
Below is a graph of 12 month moving average global temperature anomalies since April 1994 from seven of the world’s leading global temperature series. None of them are as quick of the mark at reporting their results like 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., but all show the recent surge that started at the beginning of 2023. The 30 year linear trend on the ERA5 series shows an increase of +0.24°C per decade over that time, and the warming trend that started in 1970 is starting to accelerate.
