The decrease of Arctic sea ice, minimum extent in 1982 and 2007, and climate projections [Norwegian]
Sattelite observations of the september extent of sea ice in the Arctic shows in 2007 shows a 23% decrease from the previous minimum, in 2005, and 39% below the average minimum extent for the time period 1979-2000. The b...

Projected changes in Arctic pack ice (sea ice minimum extent)
The averages of the scenarios in the Arctic Climate Impact Assessment (ACIA) for the Arctic sea ice extent (the permanent ice) are presented in this map, with the successive decrease in the ice up to 2090. The projection...

Shift in climatic zones, Arctic scenario
The scenarios from the Arctic Climate Impact Assessment (ACIA) project that temperatures will increase dramatically in the Arctic, more than in many other parts of the world. This leads to effects, such as the decrease o...

Temperature increase in the Arctic, 2090 scenario
The averages of the scenarios in the Arctic Climate Impact Assessment (ACIA) are presented in this figure, for the year 2090. The Arctic is a place where the effects of climate change are already very visible, and scenar...
