The snow cover and the length it lies on the ground is important to monitor for a number of elements that affect terrestrial ecosystems. The albedo is reduced when the period of snow-covered ground is shortened, creating a positive feedback mechanism for the climate, one of the main reasons for monitoring it. Reduced snow cover during spring ...
Snow cover has decreased in most populated areas due to winter warming; days/year with 25 cm snow cover in 1991-2020 is 26 days in Oslo (94 m), 2 days in Bergen, 8 days in Trondheim/Værnes and 144 days in Tromsø. The strongest warming has been observed on Svalbard.
Environmental monitoring - recording of selected climatic features and conducting analyses of chemical buildup of air and water pollution and the isotopic content of the snow cover. In summers and winters, the station functions as a base for research on geology, geodesics, geomorphology, glaciology, oceanology and biology.
The Arctic desert ecoregion (WWF ID: PA1101) is a terrestrial ecoregion that covers the island groups of Svalbard, Franz Josef Land, Severny Island and Severnaya Zemlya in the Arctic Ocean, above 75 degrees north latitude. The region is covered with glaciers, snow, and bare rock in a harshly cold environment.
Snow cover has also decreased in most populated areas due to winter warming. The strongest warming has been observed on Svalbard. In addition to warming, precipitation has increased in most areas, especially in winter, increasing erosion and the risk of landslides.
Two songbirds migrate to Svalbard to breed: the snow bunting and the northern wheatear. Rock ptarmigan is the only bird to overwinter. [178] Remains of Predator X (Pliosaurus funkei) from the Jurassic period were discovered here. It is one of the largest dinosaur-era marine reptiles ever found.

Although Svalbard is in Norwegian territory, and its government controls 99.5% of its land, there’s a sizable Russian presence in the archipelago, thanks to a treaty dating back to 1920 that ...
Snow typically covers the town from November to March. The warmest temperature ever recorded in Longyearbyen was 21.7 °C (71.1 °F) in July 2020 and the coldest was −46.3 °C (−51.3 °F) in March 1986. Svalbard and Longyearbyen are among the places in the world that have warmed fastest in the latest decades. The 1991–2020 averages show ...
