Climate Change Impacts to Water Availability in Alaska Summary

Created: 10/20/2009 - Updated: 9/24/2019


Alaska is already showing evidence of climate change. Increases in temperature and changes in precipitation have had profound effects on regional hydrology, including shrinking wetlands, glacier and polar sea ice recession, permafrost melting, and an increase in fire frequency and intensity across the landscape as a result of increased drought and thunderstorms. Continuation of these trends will likely lead to further changes in the hydrologic cycle, with significant implications for the people, places, and wildlife that depend on Alaska’s water resources.
