Climate - Surface Waters Change Middle Water Runoff (MQ)

Change in mean water runoff (MQ) in the future. The changes are expressed as percentage increases or decreases of a 30-year mean for the near future (2021-2050) or for the distant future (2071-2100) compared to a reference period (1971-2000). The database consists of simulated outflows from various hydrological or statistical models on a daily value basis, which were driven by data from an ensemble of eight regional climate models (from the EURO-CORDEX project) on the basis of a scenario without climate protection (RCP8.5). This scenario describes a future development of humanity, in which the energy supply is essentially based on the combustion of fossil fuels and the emission of greenhouse gases leads to a steady increase in radiative forcing until the year 2100. The median represents the mean trend from the range of the various change signals of the ensemble members, the maximum value represents the upper bandwidth, the minimum value the lower bandwidth.
