The areal extent, concentration and thickness of sea ice in the Arctic Ocean and adjacent seas have strongly decreased during the recent decades, but cold, snow-rich winters have been common over mid-latitude land areas since 2005. The climate change in the Arctic has been at least twice as fast as the global everage. One of the most dramatic indicators of the Arctic warming has been the decline in the sea ice cover. This has been manifested as a decrease in the ice extent, ice thickness, and the length of the ice season. Due to the availability of satellite passive microwave remote sensing data, the changes in ice extent have been reasonably well documented since 1979. The change has been most dramatic in summer and autumn, with approximately 50 % decrease since the beginning of the satellite record. Related to the decreased ice extent, the period with sea ice cover has become remarkably shorter over large areas. Arctic sea ice also has strong feedback effects on the other components of the climate system. My presentation is about couses of arctic sea ice decline and it’s effects to the global climate.
