Germany is one of the regions with the highest loss of water worldwide due to global warming. The annual losses amount to 2.5 cubic kilometers. By comparison, Lake Constance contains around 48 cubic kilometers of water. The new monitoring report on the „German Strategy for Adaptation to Climate Change“ (DAS) shows that the consequences are far-reaching. For example, the past few years have been marked by severe regional droughts. In many places, groundwater levels fell to record lows. This resulted in a 15 to 20 percent drop in wheat and silage maize harvests in some years. Forests, especially spruce stands, suffered from the drought stress and died in some areas. The drought caused major forest fires, particularly in the northeastern federal states. In addition, heatwaves with temperatures of over 40 degrees Celsius north of Hamburg occurred for the first time, as well as far-reaching changes in the ecosystems in the sea and on land.
