Permafrost is a distinct feature of the terrestrial Arctic and is vulnerable to climate warming.
Permafrost degrades in different ways, including deepening of a seasonally unfrozen …

The paradigm that permafrost-affected soils show restricted mineral nitrogen (N) cycling in
favor of organic N compounds is based on the observation that net N mineralization rates in …

Northern permafrost soils store a vast reservoir of carbon, nearly twice that of the present
atmosphere. Current and projected climate warming threatens widespread thaw of these …

The permafrost organic carbon (OC) stock is of global significance because of its large pool
size and the potential positive feedback to climate warming. However, due to the lack of …

The sign and magnitude of permafrost carbon (C)-climate feedback are highly uncertain due
to the limited understanding of the decomposability of thawing permafrost and relevant …

We present an approach to estimate the feedback from large-scale thawing of permafrost
soils using a simplified, data-constrained model that combines three elements: soil carbon …

In contrast to the well-recognized permafrost carbon (C) feedback to climate change, the fate
of permafrost nitrogen (N) after thaw is poorly understood. According to mounting evidence …

The large amounts of soil organic matter (SOM) in permafrost-affected soils are prone to
increased microbial decomposition in a warming climate. The environmental parameters …

High-latitude soils store vast amounts of perennially frozen and therefore inert organic
matter. With rising global temperatures and consequent permafrost degradation, a part of …

Ice-rich Pleistocene-age permafrost is particularly vulnerable to rapid thaw, which may
quickly expose a large pool of sedimentary organic matter (OM) to microbial degradation …
