Climate change on the Rhine: water temperature expected to rise by up to 4.2 °C by the end of the century

The water temperatures of the Rhine are rising. This is shown by an analysis carried out in 2024 by the German Federal Institute of Hydrology (BfG) and the Dutch research institute Deltares as part of their work for the International Commission for the Protec-tion of the Rhine (ICPR). Effects on ecology and the economy are already being ob-served and will intensify in the future.
