The Arctic is warming three times as fast and the global average. This is mainly because melting of snow and ice exposes a darker surface and increases the amount of solar energy absorbed in these areas (albedo effect). This significant regional warming leads to continued loss of sea ice, melting of glaciers and of the Greenland ice cap.

Arctic ecosystems in fresh water

The lake ecosystems in Svalbard are largely characterised by low precipitation, thick, clear ice (1.5–2 m), a brief ice-free period (1–2 months), relatively low water temperatures in summer (up to 6–7°C), low nutrient input, low primary production, low biodiversity, with Arctic char as the only fish species.
