For the first time, the “German Weather Service”: http: //www.dwd.de/DE/Home/home_node.html (DWD) has forecasted the climate development of Hamburg and its metropolitan region for the year 2050. According to the survey, the average city temperature will be 1.2 degrees warmer than today. More “critical” is according to DWD Vice President Dr. Paul Becker “the near doubling of hot days with a maximum temperature of around 30 degrees.” Precipitation, thus theeclimatologists, will also continue to grow, especially in winter. Hamburg will have to adapt to heavy rainfall. “But it is possible to respond to the impact of climate change by targeted urban planning”, said Becker.
More City Trees
Jens Kerstan, Hamburg Minister of the Environment, calls the climate simulation of the German Weather Service as a clear sign for Hamburg to intelligently respond to the challenges of climate change, even though the need for densification is felt. Of particular importance is thus the preservation of Hamburg’s green landscape with parks and tree-lined streets. “City trees and green spaces provide shade and cooler areas on hot days. We are planting tree species that are suitable for the changing climate”, Kerstan stated.
Adjustments in Infrastructure
Green facades and roofs can protect the interior from heating up in poorly insulated buildings. The “Hamburg Green Roof Campaign”: http: //www.hamburg.de/gruendach/ offer builders financial incentives. Another important response to changing climatic conditions is the Rain infrastructure adaptation (RISA) project with its solutions to prevent flooding and additional water pollution. At some schools and residential construction projects, special features have been integrated to make use of rainwater.
The study of the DWD on the changing climate of Hamburg and its metropolitan region analyses the climatic correlation between the City of Hamburg, its surroundings and its proximity to the coast. For Hamburg, a special climate model has been developed that take into consideration the different city structures, i.e. sealed surfaces, green land, water, and wetlands.
