Widespread permafrost degradatation is expected by the end of the century across Alaska.

Models of annual mean ground temperature at 1 meter depth project the area of above-freezing ground will expend dramatically during the 21st century under all climate scenarios. This warming is especially pronounced in the second half of the century, covering much of interior Alaska in the higher climate scenarios. By the end of the century, stable permafrost may only exist in the northern third of the state.
