The comparison of the two extreme scenarios SSP1-2.6 ("2-degree target") and SSP 5-8.5 ("No further climate protection measures") with MPI-ESM LR shows for the sea ice cover in the Arctic that extent and concentration decrease in both cases and in both seasons compared to today. However, sea ice would also remain in summer with SSP1-2. 6 until the end of the century, while just the summer (September) sea ice for scenario SSP5-8.5 would completely disappear from 2070 on according to these calculations.
Video: Temporal evolution of Arctic sea ice cover in September (white) and in March (light blue) for scenarios SSP1-2.6 and SSP5-8.5 based on simulations with MPI-ESM LR (ensemble means, 10 realizations). For the time period from 1975 to 2014, the visualization shows the simulated historical past on both sides.
