This raster, created in 2010, is output from the Geophysical Institute Permafrost Lab (GIPL) model and represents simulated mean annual ground temperature (MAGT) in Celsius, averaged across a decade, at the base of active layer or at the base of the seasonally frozen soil column. The file name specifies the decade the raster represents. For example, a file named MAGT_1980_1989.tif represents the decade spanning 1980-1989. Cell values represent simulated mean annual ground temperature (degree C) at the base of the active layer (for areas with permafrost) or at the base of the soil column that is seasonally frozen (for areas without permafrost). If the value of the cell is negative,the area has permafrost and the...
Results indicate that the regions most vulnerable to ecological shifts under the influence of climate change are likely to be the interior and northern mountainous portions of Alaska; the northern Yukon; and much of the Northwest Territories. Although the A1B and A2 emissions scenarios predict more cliome shift overall, as compared to the more conservative B1 scenario, the patterns hold true across all three. Notably, there are no areas of the NWT predicted to retain their current cliomes.
