An Initial Estimate of the Cost of Lost Climate Regulation Services Due to Changes in the Arctic Cryosphere [PDF]
, 2010 Outlines how arctic sea ice and snow cover help maintain the global climate and ecosystems, the impact of changes in sea and land reflectivity and methane emissions, research on the social cost of carbon, and the estimated economic cost of climate ...

Remote sensing of rapid permafrost landscape dynamics
, 2017 The global climate is warming and the northern high latitudes are affected particularly rapidly. Large areas of this region, or 24% of the northern hemisphere, are influenced by perennially frozen ground or permafrost. As permafrost is predominantly dependent on cold mean annual air temperatures, climate warming threatens the stability of permafrost ...

Origin and structure of Devensian depressions at Letton, Herefordshire [PDF]
, 2010 Groups of circular to oval enclosed depressions in soft sediments of Pleistocene age are relatively common in north-west Europe. These features are normally interpreted as being either glacial or periglacial in origin.

Climate and Hydrogeological Controls on Water Tracks in Permafrost Landscapes
Reviews of GeophysicsAbstractClimate change drives disturbance in hydrology and geomorphology in terrestrial polar landscapes underlain by permafrost, yet measurements of, and theories to understand, these changes are limited. Water flowing from permafrost hillslopes to channels is often modulated by water tracks, zones of enhanced soil moisture in unchannelized ...

Policy implications of warming permafrost [PDF]
Permafrost is perennially frozen ground occurring in about 24% of the exposed land surface in the Northern Hemisphere. The distribution of permafrost is controlled by air temperature and, to a lesser extent, by snow depth, vegetation, orientation to ...

The impact of lateral heat and water fluxes from thermokarst lakes on tundra landscape dynamics and permafrost degradation [PDF]
, 2018 Projected future warming of the Arctic will result in pronounced degradation of permafrost and thereby trigger large-scale landscape and ecosystem changes.
