Arctic sea ice - a disappearing phenomenon
Since 1978 Arctic sea ice (ASI) is monitored via satellite-borne multichannel passive microwave radiometers, which provide generally consistent estimates of long term trends. Earlier records are based on proxies. It becomes evident that now ASI-loss is highest in summer and the sustained declining trend is unprecedented in the last 1,450 years. Because of natural variability and a complex feedback system, predictions of when the Arctic will be ice free should be taken with little confidence. Yet ASI seems to respond roughly linear to temperature and models display the possibility of ice free summers by the end of the century.
