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 feedback to atmospheric CO2 and CH4 concentrations and accelerates climate change1,2. Current studies report a minor importance of CH4 production in water-saturated (anoxic) permafrost soils3–6 and a stronger permafrost carbon–climate feedback from drained (oxic) soils1,7. Here we show through seven-year laboratory… 

Carbon Dioxide and Methane Release Following Abrupt Thaw of Pleistocene Permafrost Deposits in Arctic Siberia

The decomposition of thawing permafrost organic matter (OM) to the greenhouse gases (GHG) carbon dioxide (CO2) and methane forms a positive feedback to global climate change. Data on in situ GHG

Ecosystem carbon response of an Arctic peatland to simulated permafrost thaw

It is shown here that, under dry conditions, peatlands strengthen the permafrost-carbon feedback by adding to the atmospheric CO2 burden post-thaw, with the potential to compensate part of thepermafrost CO2 losses over longer timescales.

A synthesis of methane dynamics in thermokarst lake environments

Relationships between greenhouse gas production and landscape position during short-term permafrost thaw under anaerobic conditions in the Lena Delta

. Soils in the permafrost region have acted as carbon sinks for thousands of years. However, as a result of global warming, permafrost soils are thawing and will potentially release more greenhouse

Greenhouse gas production in degrading ice-rich permafrost deposits in northeastern Siberia

Abstract. Permafrost deposits have been a sink for atmospheric carbon for millennia. Thaw-erosional processes, however, can lead to rapid degradation of ice-rich permafrost and the release of

Increasing Organic Carbon Biolability With Depth in Yedoma Permafrost: Ramifications for Future Climate Change

Permafrost thaw subjects previously frozen organic carbon (OC) to microbial decomposition, generating the greenhouse gases (GHG) carbon dioxide (CO2) and methane (CH4) and fueling a positive climate

Experimental Soil Warming and Permafrost Thaw Increase CH4 Emissions in an Upland Tundra Ecosystem

Rapid Arctic warming is causing permafrost to thaw and exposing large quantities of soil organic carbon (C) to potential decomposition. In dry upland tundra systems, subsidence from thawing

Microbial Greenhouse Gas Dynamics Associated With Warming Coastal Permafrost, Western Canadian Arctic

Permafrost sediments contain one of the largest reservoirs of organic carbon on Earth that is relatively stable when it remains frozen. As air temperatures increase, the shallow permafrost thaws



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

Changes in peat chemistry associated with permafrost thaw increase greenhouse gas production

The results imply that subsidence and thermokarst-associated increases in organic matter lability cause shifts in biogeochemical processes toward faster decomposition with an increasing proportion of carbon released as CH4.

Predicting long-term carbon mineralization and trace gas production from thawing permafrost of Northeast Siberia.

The objective of the current study is to quantify the potential long-term release of trace gases from permafrost organic matter and to more reliably constrain projections of future trace gas fluxes from thawingpermafrost landscapes.

Temperature and peat type control CO2 and CH4 production in Alaskan permafrost peats

Temperature, moisture, organic matter, and microbial controls on soil organic carbon (SOC) losses following permafrost thaw in peat soils across Alaska, and carbon dioxide and methane emissions varied depending on the peat type and peat decomposition stage rather than thermal state.

Limited contribution of permafrost carbon to methane release from thawing peatlands

Methane fluxes from thawing peatlands in northern Canada were derived predominantly from anaerobic decomposition of recent vegetation rather than from previously frozen material — as is typically

The rate of permafrost carbon release under aerobic and anaerobic conditions and its potential effects on climate

Recent observations suggest that permafrost thaw may create two completely different soil environments: aerobic in relatively well‐drained uplands and anaerobic in poorly drained wetlands. The soil

Methane emissions proportional to permafrost carbon thawed in Arctic lakes since the 1950s

Warming thaws permafrost, releasing carbon that can cause more warming. Radiocarbon, soil carbon, and remote sensing data suggest that 0.2–2.5 Pg of carbon has been emitted from permafrost as CO2 and

Warming of subarctic tundra increases emissions of all three important greenhouse gases – carbon dioxide, methane, and nitrous oxide

Experimental air warming increased emissions of all three greenhouse gases (GHGs), including the highly understudied N2O, clearly demonstrating the need to include N1O in future Arctic GHG budgets.

Effect of permafrost thaw on CO2 and CH4 exchange in a western Alaska peatland chronosequence

Permafrost soils store over half of global soil carbon (C), and northern frozen peatlands store about 10% of global permafrost C. With thaw, inundation of high latitude lowland peatlands typically

A pan-Arctic synthesis of CH4 and CO2 production from anoxic soil incubations.

The results demonstrate that as climate warms in arctic and boreal regions, rates of anaerobic CO2 and CH4 production will increase, not only as a result of increased temperature, but also from shifts in vegetation and increased ground saturation that will accompany permafrost thaw.
