Deep soil profiles containing permafrost (Gelisols) were characterized for organic carbon (C) and total nitrogen (N) stocks to 3 m depths. Using the Community Climate System Model (CCSM4) we calculate cumulative distributions of active layer thickness (ALT) under current and future climates. The difference in cumulative ALT distributions over time was multiplied by C and N contents of soil horizons in Gelisol suborders to calculate newly thawed C and N. Thawing ranged from 147 PgC with 10 PgN…

Thawing Permafrost as a Nitrogen Fertiliser: Implications for Climate Feedbacks

Studies for the northern high latitudes suggest that, in the near term, increased vegetation uptake may offset permafrost carbon losses, but over longer time periods, permafrost carbon decomposition

Circumpolar assessment of permafrost C quality and its vulnerability over time using long‐term incubation data

Variation in the vulnerability of C stored in permafrost soils based on inherent differences in organic matter decomposability is demonstrated, and point toward C : N as an index of decomposable that has the potential to be used to scalepermafrost C loss across landscapes.

Permafrost Thaw and Liberation of Inorganic Nitrogen in Eastern Siberia

The currently observed climate warming will lead to widespread degradation of near‐surface permafrost, which may release substantial amounts of inorganic nitrogen (N) into arctic ecosystems. We

Characterisation of the Permafrost Carbon Pool

The current estimate of the soil organic carbon (SOC) pool in the northern permafrost region of 1672 Petagrams (Pg) C is much larger than previously reported and needs to be incorporated in global

The impacts of recent permafrost thaw on land–atmosphere greenhouse gas exchange

Permafrost thaw and the subsequent mobilization of carbon (C) stored in previously frozen soil organic matter (SOM) have the potential to be a strong positive feedback to climate. As the northern

Potential carbon emissions dominated by carbon dioxide from thawed permafrost soils

A meta-analysis of soil incubation studies from the permafrost zone suggests that thawing under aerobic conditions, which releases CO2, will strengthen the permafrost carbon feedback more than

Widespread capacity for denitrification across a boreal forest landscape

A warming climate combined with frequent and severe fires cause permafrost to thaw, especially in the region of discontinuous permafrost, where soil temperatures may only be a few degrees below 0 °C.

Permafrost thawing puts the frozen carbon at risk over the Tibetan Plateau

A comprehensive investigation on the spatiotemporal dynamics of SOC over the high-altitude Tibetan Plateau, which has received less attention compared with the circum-Arctic region, highlights the importance of deep permafrost thawing that is generally ignored in current Earth system models.

Observation-based modelling of permafrost carbon fluxes with accounting for deep carbon deposits and thermokarst activity

Abstract. 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 this carbon

Permafrost carbon in a changing Arctic

Organic matter (OM) in arctic permafrost ground contains about twice as much carbon (C) as is currently present in the atmosphere. Climate change is particularly strong in the Arctic, and could cause



Potential carbon release from permafrost soils of Northeastern Siberia

Permafrost soils are an important reservoir of carbon (C) in boreal and arctic ecosystems. Rising global temperature is expected to enhance decomposition of organic matter frozen in permafrost, and

Potential carbon release from permafrost soils of Northeastern Siberia

Permafrost soils are an important reservoir of carbon (C) in boreal and arctic ecosystems. Rising global temperature is expected to enhance decomposition of organic matter frozen in permafrost, and

Permafrost carbon-climate feedbacks accelerate global warming

A terrestrial ecosystem model that includespermafrost carbon dynamics, inhibition of respiration in frozen soil layers, vertical mixing of soil carbon from surface to permafrost layers, and CH4 emissions from flooded areas is used, to explore the potential for carbon-climate feedbacks at high latitudes.

Deep metagenomic sequencing is used to determine the impact of thaw on microbial phylogenetic and functional genes, and relate these data to measurements of methane emissions, and construct the first draft genome from a complex soil metagenome, which corresponds to a novel methanogen.
