Historical change of the sea ice cover


Since 1978 satellites are measuring the changes in sea ice cover in the Arctic and Antarctic. The long-term review shows a decline of the sea ice cover in the Arctic region. In the opposite case there is detectable an increase in sea ice covering the Antarctic region.
