Permafrost has received much attention recently because surface temperatures are rising in most permafrost areas of the earth, bringing permafrost to the edge of widespread thawing and degradation. Furthermore, changing climate may cause a change in storm pathways, bringing more frequent or intense storms to some parts of Alaska. This web site is based upon work supported by the National Science Foundation under Cooperative Agreement No. Extreme precipitation events are also expected to increase and would enhance the risk of flooding and the possible impact on culverts and bridge supports and foundations. The potential active layer depth increase was calculated by subtracting current sediment active layer depths from future bedrock active layer depths. The three main variables are sediment or rock type, presence and amount of ground ice, and the ground thermal conditions.
