RT null T1 The shrinking Arctic Sea Ice - Foresight Brief T2 Le recul des glaces de mer arctiques - Note Perspective A1 United Nations Environment Programme, K1 ice K1 Arctic region K1 global warming K1 environmental monitoring YR 2022 FD 2022-02 LK https://wedocs.unep.org/handle/20.500.11822/38414 UL https://wedocs.unep.org/handle/20.500.11822/38414 NO The Arctic is a remote and sparsely inhabited area. It is connected to the rest of the world by our climate system, the atmosphere surrounding our Earth and by global ocean currents. Since satellite measurements started 40 years ago, about half of the sea ice area in the Arctic has been lost. The shrinking summer sea ice cover is a visible manifestation of global warming, and affects marine ecosystems, ocean circulation, and potentially weather events further south of the Arctic.
