The comparison of the two extreme scenarios SSP1-2.6 ("2-degree target") and SSP 5-8.5 ("No further climate protection measures") 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 in SSP1-2.6 until the end of the century, while just the summer (September) sea ice in SSP5-8.5 would completely disappear from 2070 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 HR. With this model these two scenarios were calculated only once each, therefore the visualization shows a relatively high variability from year to year.
