Global methane emissions from natural wetlands and carbon release from permafrost thaw have a positive feedback on climate, yet are not represented in most state-of-the-art climate models. Furthermore, a fraction of the thawed permafrost carbon is released as methane, enhancing the combined feedback strength. We present simulations with an inverted intermediate complexity climate model, which follows prescribed global warming pathways to stabilization at 1.5 or 2.0 °C above pre-industrial… 

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

WETMETH 1.0: A new wetland methane model for implementation in Earth system models

Abstract. Wetlands are the single largest natural source of methane (CH4), a powerful greenhouse gas affecting the global climate. In turn, wetland CH4 emissions are sensitive to changes in climate

Timescales of the permafrost carbon cycle and legacy effects of temperature overshoot scenarios

It is shown that feedbacks between water-, energy- and carbon cycles allow for multiple steady-states in permafrost regions, which differ with respect to the physical state of the soil, the soil carbon concentrations and the terrestrial carbon uptake and -release.

Significant feedbacks of wetland methane release on climate change and the causes of their uncertainty

Emissions from wetlands are the single largest source of the atmospheric greenhouse gas (GHG) methane (CH4). This may increase in a warming climate, leading to a positive feedback on climate change.

Mitigation of Arctic permafrost carbon loss through stratospheric aerosol geoengineering

It is shown that stratospheric sulfate aerosol injection geoengineering can help to avoid about 14 gigatons of carbon release and US$8.4 trillion in economic losses by 2070 compared to RCP4.5 emissions.

Permafrost carbon emissions in a changing Arctic

Arctic permafrost stores nearly 1,700 billion metric tons of frozen and thawing carbon. Anthropogenic warming threatens to release an unknown quantity of this carbon to the atmosphere, influencing

Diverging responses of high-latitude CO2 and CH4 emissions in idealized climate change scenarios

Abstract. The present study investigates the response of the high-latitude carbon cycle to changes in atmospheric greenhouse gas (GHG) concentrations in idealized climate change scenarios. To this

Permafrost and Climate Change: Carbon Cycle Feedbacks From the Warming Arctic

Rapid Arctic environmental change affects the entire Earth system as thawing permafrost ecosystems release greenhouse gases to the atmosphere. Understanding how much permafrost carbon will be

Evidence for ecosystem state shifts in Alaskan continuous permafrost peatlands in response to recent warming

Regional variation in the effectiveness of methane-based and land-based climate mitigation options

Abstract. Scenarios avoiding global warming greater than 1.5 or 2 ∘C, as stipulated in the Paris Agreement, may require the combined mitigation of anthropogenic greenhouse gas emissions alongside



CO2 loss by permafrost thawing implies additional emissions reductions to limit warming to 1.5 or 2 °C

Large amounts of carbon are stored in the permafrost of the northern high latitude land. As permafrost degrades under a warming climate, some of this carbon will decompose and be released to the

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

Quantifying uncertainties of permafrost carbon–climate feedbacks

Abstract. The land surface models JULES (Joint UK Land Environment Simulator, two versions) and ORCHIDEE-MICT (Organizing Carbon and Hydrology in Dynamic Ecosystems), each with a revised

Cumulative carbon emissions budgets consistent with 1.5 °C global warming

The Paris Agreement1 commits ratifying parties to pursue efforts to limit the global temperature increase to 1.5 °C relative to pre-industrial levels. Carbon budgets2–5 consistent with remaining

Acceleration of global warming due to carbon-cycle feedbacks in a coupled climate model

Results from a fully coupled, three-dimensional carbon–climate model are presented, indicating that carbon-cycle feedbacks could significantly accelerate climate change over the twenty-first century.

Emission budgets and pathways consistent with limiting warming to 1.5 °C

The Paris Agreement has opened debate on whether limiting warming to 1.5 °C is compatible with current emission pledges and warming of about 0.9 °C from the mid-nineteenth century to the present

Variability in the sensitivity among model simulations of permafrost and carbon dynamics in the permafrost region between 1960 and 2009

A significant portion of the large amount of carbon (C) currently stored in soils of the permafrost region in the Northern Hemisphere has the potential to be emitted as the greenhouse gases CO2 and

Climate change and the permafrost carbon feedback

It is found that current evidence suggests a gradual and prolonged release of greenhouse gas emissions in a warming climate and a research strategy with which to target poorly understood aspects of permafrost carbon dynamics is presented.

Climate feedback from wetland methane emissions

The potential for wetland emissions to feedback on climate change has been previously hypothesised [ Houghton et al., 2001 ]. We assess this hypothesis using an interactive wetlands scheme

Radiative forcing of carbon dioxide, methane, and nitrous oxide: A significant revision of the methane radiative forcing

New calculations of the radiative forcing (RF) are presented for the three main well‐mixed greenhouse gases, methane, nitrous oxide, and carbon dioxide. Methane's RF is particularly impacted because
