In terms of areal extent, frozen ground is the largest component of the Earth cryosphere. It plays an important role in land surface energy and moisture balances, hydrologic and biochemical cycles, have profound effect on ecosystems and characterized by unique land surface and geomorphologic processes.  Frozen ground environments are also a home of substantial human population and the area of significant economic activity. A wide range of environmental changes occurring over the last few years to millennia significantly affect frozen ground regions.  Impacts of a recently warming climate are increasingly evident. These climatic trends are producing substantive impacts on ecosystems, social structures, geomorphology and other physical or biological processes of frozen ground environments.   This session seeks presentations from multiple disciplines that document and examine the nature of changes effecting frozen ground environments. Organizers invite presentations that use models, observations, historical and paleoclimate records, statistical inference, and process studies addressing past present and future of frozen ground environments. We also encourage presentations addressing effects of frozen ground changes on human population, economic activities as well as policy issues related to the need for multi-national collaborations in frozen ground research and to improve the public's awareness of climate processes and change.
