Everybody is talking about climate change in the arctic, but what is actually going on? The Norwegian Polar Institute, through its MOSJ-project (environmental monitoring of Svalbard and Jan Mayen), has gathered a range of data that make it quite clear that accelerating climate change is a measurable fact: the temperature has a tendency to increase during most of the 20th century, with a marked and still increasing acceleration in recent years. Precipitation is following, although the trend is less pronounced and clear here.
The sea ice has decreased by 35-40 % (area; referring to maximum distribution in April) from 1979 to 2009, and it is getting thinner: from 1.20 meters (1966) to 0,80 meters (2006) around Hopen island. Temperatures at the top level of the permafrost are by now increasing as fast as 1°C per decade, and glaciers around Ny Ålesund have lost 15 meters of average thickness, also here with a strongly accelerating tendency in recent years.
