One catastrophic impact of changing vegetation on permafrost is likely to be an increased frequency of fires. Wildfire is a major disturbance in the Arctic tundra and boreal forests, which has a significant impact on soil hydrology, carbon cycling, and permafrost dynamics. Thawing permafrost is ...

As the frozen ground warms much faster than expected, it’s reshaping the landscape—and releasing carbon gases that fuel global warming.
Major themes of the volume, which includes 15 contributions, include spatiotemporal dynamics of permafrost and the active layer, soil genesis and classification, hydrology, soil and vegetation succession, and elemental movement and nutrient cycling. Suggested major future directions are that a regional ...
Arctic warming is affecting snow cover and soil hydrology, with consequences for carbon sequestration in tundra ecosystems. The scarcity of observations in the Arctic has limited our understanding of the impact of covarying environmental drivers on the c

Furthermore, tundra ecosystems are leaky with respect to nutrients, which may have ramifications well beyond the disturbance both with respect to time and space, and bears attention in assessing the future response of tundra ecosystems.doi:10.2307/1552113Giles M. Marion...
Report presenting the findings of the Snow, Water, Ice and Permafrost in the Arctic (SWIPA): Climate Change and the Cryosphere assessment performed by the Arctic Monitoring and Assessment Programme (AMAP) in close cooperation with the International Arctic Science Committee (IASC), the World Climate...
Increasing trends in cold-season minimum flow is also observed in most of the Arctic, suggesting widespread changes in subsurface hydrology (Rennermalm and Wood, 2010). Furthermore, thermokarst lakes depend on permafrost, with lakes forming where melting of ground-ice and surface settlement initiate...
Experience with using permafrost for disposal of various toxic industrialwaste products and for storage of oils and petroleum products shows that underground disposal is preferable in terms of ecology and economy. However, account must be taken of possible interaction (heat, mechanical, chemical, and ...
