The decrease of Arctic sea ice, minimum extent in 1982 and 2007, and climate projections [Norwegian] 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 bottom part of this graphic shows the development according to the Arctic Climate Impact Assessment (ACIA) and the merging of five global climate models - the resultant projections shows sucessive decreases for this century. The Ar...

Projected changes in Arctic pack ice (sea ice minimum extent) 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 projections are based on the models of the IPCC Third Assessment Report (IPCC TAR).

Projected changes in the Arctic climate, 2090 - with shipping routes Projected changes in the Arctic climate, 2090 - with shipping routes
The averages of the scenarios in the Arctic Climate Impact Assessment (ACIA) are presented in this figure, for the year 2090, with the surface temperatures over land, the size of the polar ice cap, and the outer limits of permafrost. This map features shipping routes in addition - as the sea ice is decreasing, the potential for developing shipping in the Arctic increases.

Shift in climatic zones, Arctic scenario 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 of area (e.g. tundra) under continous permafrost, the northward move of the tree line and the decrease of Arctic Sea Ice. The synthesis is based on several different models and ensables and this map depicts the situation at the end...

Temperature increase in the Arctic, 2090 scenario 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 scenarios suggests that this will be one of the regions were the effects will be at its strongest.
