TL;DR: In this article, the authors reported a new estimate of the carbon pools in soils of the northern permafrost region, including deeper layers and pools not accounted for in previous analyses.

TL;DR: In this article, the authors present an overview of the global permafrost C pool and of the processes that might transfer this C into the atmosphere, as well as the associated ecosystem changes that occur with thawing.

TL;DR: In this article, the authors used a terrestrial ecosystem model that includes permafrost carbon dynamics, inhibition of respiration in frozen soil layers, vertical mixing of soil carbon from surface-to-perfrost layers, and CH4 emissions from flooded areas, to explore the potential for carbon-climate feedbacks at high latitudes.

TL;DR: In this article, the authors compared 11 Earth System Models (ESMs) to empirical data from the Harmonized World Soil Database (HWSD) and the Northern Circumpolar Soil Carbon Database (NCSCD).

TL;DR: In this article, the vulnerability of the North American high-latitude soil organic carbon (SOC) pool to climate change has been discussed, where the authors divide the current northern highlatitude organic carbon pools into near-surface soils where SOC is affected by seasonal freeze-thaw processes and changes in moisture status, and deeper permafrost and peatland strata down to several tens of meters depth where organic carbon is usually not affected by short-term changes.
