How to create a multi-model of C3S Seasonal Forecasts with xarray and Python

Among the data products of the Copernicus Climate Change (C3S) available through the Climate Data Store, there is a collection of seasonal forecasts, from the 13th November consisting of five different models (ECMWF, UK Met Office, Meteo-France, DWD and CMCC). One of the interesting things you can do with multiple climate models is to combine them into a multi-model ensemble. With Python and xarray this is very simple. However, although the CDS has made the retrieval of climate data more user-friendly than in the past (nice web interface, API in Python, documentation, etc.

Temperature of European rivers and future climate in 50 lines of R code

During the last summer the water temperature in some important rivers (especially the Rhine and the Rhone) in central Europe was so high that some nuclear and coal power plants in Germany, France and Switzerland had to limit their generation or even shut down due to the regulations imposing them to do not discharge the warm water used for cooling the plant when the river temperature was too high. It was July, during a heatwave strong enough to deserve a Wikipedia page.
