»Durch den Klimawandel sind hunderttausende Deutsche von Überflutungen bedroht«

Studie des Potsdam-Instituts für Klimafolgenforschung, 10.1.2018 (engl. Originalfassung)

Earth’s surface temperature will continue to rise for another 20 to 30 years even with the strongest carbon emission reduction currently considered. The associated changes in rainfall patterns can result in an increased flood risk worldwide. We compute the required increase in flood protection to keep high-end fluvial flood risk at present levels. The analysis is carried out worldwide for subnational administrative units. Most of the United States, Central Europe, and Northeast and West Africa, as well as large parts of India and Indonesia, require the strongest adaptation effort. Germany in total needs to adapt to an increase in flood risk with 710,000 people affected in the future period. More than half of the United States needs to at least double their protection within the next two decades. Thus, the need for adaptation to increased river flood is a global problem affecting industrialized regions as much as developing countries.
