Arctic coasts are vulnerable to the effects of climate change, including rising sea levels and
the loss of permafrost, sea ice and glaciers. Assessing the influence of anthropogenic …

Where present, permafrost exerts a primary control on water fluxes, flowpaths, and
distribution. Climate warming and related drivers of soil thermal change are expected to …

Intensifying wildfire activity and climate change can drive rapid forest compositional shifts. In
boreal North America, black spruce shapes forest flammability and depends on fire for …

The cryosphere is defined by the presence of frozen water in its many forms: glaciers, ice
caps, ice sheets, snow, permafrost, and river and lake ice. In the extended Hindu Kush …

Permafrost thaw liberates frozen organic carbon, which is decomposed into carbon dioxide
(CO2) and methane (CH4). The release of these greenhouse gases (GHGs) forms a positive …

Permafrost degradation poses serious threats to both natural and human systems through its
influence on ecological–hydrological processes, infrastructure stability, and the climate …

Increasing temperatures in northern high latitudes are causing permafrost to thaw, making
large amounts of previously frozen organic matter vulnerable to microbial decomposition …

The boreal ecosystem is an important global reservoir of stored carbon and a haven for
diverse biological communities. The natural disturbance dynamics there have historically …

The physical and chemical changes that accompany permafrost thaw directly influence the
microbial communities that mediate the decomposition of formerly frozen organic matter …

Permafrost constitutes a major portion of the terrestrial cryosphere of the Earth and is a
unique ecological niche for cold-adapted microorganisms. There is a relatively high …
