Tundra vegetation productivity and composition are responding rapidly to climatic changes
in the Arctic. These changes can, in turn, mitigate or amplify permafrost thaw. In this Review …

The formation, growth and drainage of lakes in Arctic and boreal lowland permafrost regions
influence landscape and ecosystem processes. These lake and drained lake basin (L-DLB) …

Permafrost carbon feedback (PCF) modeling has focused on gradual thaw of near-surface
permafrost leading to enhanced carbon dioxide and methane emissions that accelerate …

The term thermokarst describes the processes and landforms that involve collapse of the
land surface as a result of the melting of ground ice. We review the literature that has …

Knowledge of soils in the permafrost region has advanced immensely in recent decades,
despite the remoteness and inaccessibility of most of the region and the sampling limitations …

We develop a permafrost classification system to describe the complex interaction of climatic
and ecological processes in permafrost formation and degradation that differentiates five …

Thermokarst lakes and drained lake basins are widespread in Arctic and sub-Arctic
permafrost lowlands with ice-rich sediments. Thermokarst lake formation is a dominant …

Quantifying changes in thermokarst lake extent is of importance for understanding the
permafrost‐related carbon budget, including the potential release of carbon via lake …

Local observations indicate that climate change and shifting disturbance regimes are
causing permafrost degradation. However, the occurrence and distribution of permafrost …

Analysis of a 60 km segment of the Alaskan Beaufort Sea coast using a time‐series of aerial
photography revealed that mean annual erosion rates increased from 6.8 ma− 1 (1955 to …
