![]() ![]() Green roofs can provide part of a solution to these projected climate change impacts by mitigating increased temperature and extreme rainfall events. In addition, available at the national level indicate an increased potential for severe storms and floods with associated risks and increased pressure on urban drainage systems. In comparison to the reference period (1971 – 2000), most simulations for the 21 st century show an increase in precipitation during winter with a range for the moderate scenario of -3 to +17 %, and from +8 to +32 % for a scenario with unabated greenhouse gas emissions. Under unabated greenhouse gas emissions, considerable intensification of temperature extremes and summer heat waves is challenging the whole Western Europe, including Germany. A stronger increase is expected in summer, with temperatures projected to increase up to 4.8° C by the end of the century. ![]() According to the National Assessment on Climate Change for Germany (2017), projections up to the end of the 21 st century compared to the reference period (1971 – 2000) show an increase of near-surface average air temperature in Germany of 1.2 to 3.2° C (considering a moderate and intermediate scenario respectively) or of 3.2 to 4.6° C (considering the continuation of the current high emissions). ![]()
