IMPACTS OF CLIMATE CHANGE ON TRANSPORTATION INFRASTRUCTURE IN ALASKA

The economy of Alaska is extraordinarily dependent on the efficiency of its limited transportation infrastructure for mineral exports, fisheries, and tourism. Gravel airstrips, many built on permafrost, tenuously uphold the standard of living of the hundreds of Alaskan communities without road connections. Global warming is projected to bring more erratic winter weather, increasing the frequency of freeze-thaw cycles. As this occurs, Alaskan roads, railways, and airport runways will suffer attendant problems and maintenance costs are likely to increase. This paper is intended to open discussion of these and other potential impacts of global warming in Alaska.
