The Arctic as an Indicator of World Climate Change
Sea ice and permafrost in the Arctic region recede at the rate of 1% annually.
In the foreseeable future, ice melting is unlikely to cause worldwide industrial disasters; however, it will be influencing climate conditions on the planet.
Main Issues Related to Climate Change in the Arctic, Based on the Report Published by the United Nations Intergovernmental Panel on Climate Change
№ Issue Scientific View 1 Global warming 0.6-0.8 °С over the last 50 years, with 1.3-1.5°С in the Arctic 2 Arctic ice shrinking Since 1978, the Arctic ice has shrunk, on average, by 2.7%, every 10 years (8% total) 3 Average temperature of the top layer of the permafrost Increased by 3 °C since 1980 4 Maximum area covered by seasonally-frozen ground Decreased in the Northern hemisphere by 7%, compared to 1950s 5 Reason of warming Global warming is likely to have been brought about by the increased volume of greenhouse gases 6 Further average climate warming Up to 0,2°C each 10 years 7 Maximum temperature increase – sea level rise by 2099 6,4 °C – 0,59 meters 8 Temperature increase in the Arctic latitudes (prognosis through 2039) 1-2 °C 9 Maximum temperature increase in the Arctic latitudes (prognosis through 2099) 5-7,5 °C 10 Arctic ice melting Gradual melting (especially during summers, possible total ice melting in summer by 2099)
