Ecosystems along the 0°C mean annual isotherm are arguably among the most sensitive to changing climate and mires in these regions emit significant amounts of the important greenhouse gas methane (CH4) to the atmosphere. These CH4 emissions are intimately related to temperature and hydrology, and alterations in permafrost coverage, which affect both of those, could have dramatic impacts on the emissions. Using a variety of data and information sources from the same region in subarctic Sweden we… 

The impact of permafrost degradation on methane fluxes : a field study in Abisko

All over the arctic and sub-arctic region global warming is affecting permafrost. When permafrost thaws, organic material becomes available for decomposition, hence an increase of greenhouse gas

Potential feedback of thawing permafrost to the global climate system through methane emission

Large amounts of soil carbon deposited in permafrost may be released due to deeper seasonal thawing under the climatic conditions projected for the future. An increase in the volume of the available

Year-round simulated methane emissions from a permafrost ecosystem in Northeast Siberia

Abstract. Wetlands of northern high latitudes are ecosystems highly vulnerable to climate change. Some degradation effects include soil hydrologic changes due to permafrost thaw, formation of deeper

Changing Lowland Permafrost in Northern Sweden: Multiple Drivers of Past and Future Trends

Climate warming is more pronounced in the Arctic than in other parts of the world. This warming affects the terrestrial cryosphere including permafrost with consequences ranging from societal impacts

Permafrost thaw driven changes in hydrology and vegetation cover increase trace gas emissions and climate forcing in Stordalen Mire from 1970 to 2014

Results indicate that discontinuous permafrost ecosystems, while still remaining a net overall sink of C, can become a positive feedback to climate change on decadal timescales.

Future vegetation changes in thawing subarctic mires and implications for greenhouse gas exchange—a regional assessment

One of the major concerns regarding climate change in high latitudes is the potential feedback from greenhouse gases (GHG) being released from thawing peat soils. In this paper we show how

Tundra permafrost thaw causes significant shifts in energy partitioning

Permafrost, a key component of the arctic and global climate system, is highly sensitive to climate change. Observed and ongoing permafrost degradation influences arctic hydrology, ecology and

Alterations To Permafrost Environments Induced By Climate Change

Permafrost environments currently cover approximately twenty-five percent of the Northern Hemisphere. However current empirical and theoretical evidence indicates that much of the existing permafrost

Global Warming and Carbon Dynamics in Permafrost Soils: Methane Production and Oxidation

The Arctic plays a key role in the Earths climate system, because global warming is predicted to be most pronounced at high latitudes, and one third of the global carbon pool is stored in ecosystems

Possible role of wetlands, permafrost, and methane hydrates in the methane cycle under future climate change: A review

We have reviewed the available scientific literature on how natural sources and the atmospheric fate of methane may be affected by future climate change. We discuss how processes governing methane

Factors controlling large scale variations in methane emissions from wetlands

Global wetlands are, at estimate ranging 115–237 Tg CH4/yr, the largest single atmospheric source of the greenhouse gas methane (CH4). We present a dataset on CH4 flux rates totaling 12 measurement

Rapid response of greenhouse gas emission to early spring thaw in a subarctic mire as shown by micrometeorological techniques

Most studies of soil/atmosphere greenhouse gas exchange in Arctic and Sub‐Arctic wetlands have been conducted by the use of small scale chamber techniques during the growing season. To improve the

Acclimation of ecosystem CO2 exchange in the Alaskan Arctic in response to decadal climate warming

Summer CO2 flux data for two Arctic ecosystems from 1960 to the end of 1998 shows that a return to summer sink activity has come during the warmest and driest period observed over the past four decades, and indicates a previously undemonstrated capacity for ecosystems to metabolically adjust to long-term changes in climate.

Siberian wetlands: Where a sink is a source

A greenhouse gas inventory can for some ecosystems be based solely on the net CO2 exchange with the atmosphere and the export of dissolved organic carbon. In contrast, the global warming effect may
