Evolution of the arctic sea ice

The evolution of sea ice and snow is an important climate indicator. Due to the reduction of ice and snow cover in a warmer climate, more solar radiation is turned to heat on the Earth’s surface, which promotes further melting (ice-albedo feedback). The animation simultaneously shows the temporal development of the mean sea ice cover in September (sea ice minimum) and in March (sea ice maximum) for the Northern Hemisphere.

Scenario RCP2.6: Sea ice cover decreases, but until 2300, both summer sea ice and winter sea ice exist.

Scenario RCP8.5: The sea ice cover decreases most extensively; the summer sea ice disappears the fastest (approximately until 2060). The winter sea ice cover also decreases strongly; as of 2150-2180, sea ice is only present at the rim of the Arctic and disappears completely from about 2200.

Scenarios: RCP 2.6 and RCP 8.5 for the period 1975-2300
