Recent warming in the Arctic, which has been amplified during the winter1–3, greatly enhances microbial decomposition of soil organic matter and subsequent release of carbon dioxide (CO2)4. However, the amount of CO2 released in winter is not known and has not been well represented by ecosystem models or empirically based estimates5,6. Here we synthesize regional in situ observations of CO2 flux from Arctic and boreal soils to assess current and future winter carbon losses from the northern… 

Tundra Underlain By Thawing Permafrost Persistently Emits Carbon to the Atmosphere Over 15 Years of Measurements

Warming of the Arctic can stimulate microbial decomposition and release of permafrost soil carbon (C) as greenhouse gases, and thus has the potential to influence climate change. At the same time,

Closing the Winter Gap—Year‐Round Measurements of Soil CO2 Emission Sources in Arctic Tundra

Non‐growing season CO2 emissions from Arctic tundra remain a major uncertainty in forecasting climate change consequences of permafrost thaw. We present the first time series of soil and microbial

Ecosystem Scale Implication of Soil CO2 Concentration Dynamics During Soil Freezing in Alaskan Arctic Tundra Ecosystems

The rates, processes, and controls on Arctic cold period soil carbon loss are still poorly understood. To understand one component of winter CO2 loss in the atmosphere, continuous measurements of

Wildfire exacerbates high-latitude soil carbon losses from climate warming

Arctic and boreal permafrost soil organic carbon (SOC) decomposition has been slower than carbon inputs from plant growth since the last glaciation. Anthropogenic climate warming has threatened this

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.

The Impacts of Climate and Wildfire on Ecosystem Gross Primary Productivity in Alaska

The increase in wildfire occurrence and severity seen over the past decades in the boreal and Arctic biomes is expected to continue in the future in response to rapid climate change in this region.

Interannual Variability of Summer Net Ecosystem CO2 Exchange in High Arctic Tundra

Arctic terrestrial ecosystems may be contributing to increasing atmospheric carbon dioxide (CO2) concentrations under amplified climate change at high‐latitudes. This research investigates how summer

Warm-season net CO2 uptake outweighs cold-season emissions over Alaskan North Slope tundra under current and RCP8.5 climate

Arctic warming has increased vegetation growth and soil respiration during recent decades. The rate of Arctic warming will likely amplify over the 21st century. Previous studies have revealed that

Pronounced and unavoidable impacts of low-end global warming on northern high-latitude land ecosystems

Arctic ecosystems are particularly vulnerable to climate change because of Arctic amplification. Here, we assessed the climatic impacts of low-end, 1.5 °C, and 2.0 °C global temperature increases

Addressing biases in Arctic–boreal carbon cycling in the Community Land Model Version 5

Abstract. The Arctic–boreal zone (ABZ) is experiencing amplified warming, actively changing biogeochemical cycling of vegetation and soils. The land-to-atmosphere fluxes of CO2 in the ABZ have the



Increased wintertime CO2 loss as a result of sustained tundra warming

Permafrost soils currently store approximately 1672 Pg of carbon (C), but as high latitudes warm, this temperature‐protected C reservoir will become vulnerable to higher rates of decomposition. In

Carbon dioxide sources from Alaska driven by increasing early winter respiration from Arctic tundra

It is found that tundra ecosystems were a net source of CO2 to the atmosphere annually, with especially high rates of respiration during early winter (October through December), providing evidence that the decadal-scale increase in the amplitude of the CO2 seasonal cycle may be linked with increasing biogenic emissions in the Arctic, following the growing season.

Cold season CO2 emission from Arctic soils

Recent evidence indicates that significant amounts of C may be lost as CO2 to the atmosphere from tundra ecosystems during the fall, winter and spring months. Because high latitude ecosystems are

Permafrost degradation stimulates carbon loss from experimentally warmed tundra.

The results highlight the importance of winter processes in determining whether tundra acts as a C source or sink, and demonstrate the potential magnitude of C release from the permafrost zone that might be expected in a warmer climate.

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.

A comparison of annual and seasonal carbon dioxide effluxes between sub-Arctic Sweden and High-Arctic Svalbard

Recent climate change predictions suggest altered patterns of winter precipitation across the Arctic. It has been suggested that the presence, timing and quantity of snow all affect microbial

High Arctic Dry Heath CO2 Exchange During the Early Cold Season

Climate change may alter the terrestrial ecosystem carbon balance in the Arctic, and previous studies have emphasized the importance of cold season gas exchange when considering the annual carbon

Annual CO2 balance of a subarctic fen in northern Europe: Importance of the wintertime efflux

[1] The annual balance of CO2 was measured on a subarctic flark fen located in northern Finland (69°08′N, 27°17′E). Measurements were conducted using the micrometeorological eddy covariance method

Seasonal patterns of carbon dioxide and water fluxes in three representative tundra ecosystems in northern Alaska

Understanding the carbon dioxide and water fluxes in the Arctic is essential for accurate assessment and prediction of the responses of these ecosystems to climate change. In the Arctic, there have

Tundra ecosystems observed to be CO2 sources due to differential amplification of the carbon cycle.

40 years of CO2 flux observations from 54 studies spanning 32 sites across northern high latitudes suggest that despite increases in growing season uptake, tundra ecosystems are currently CO2 sources on an annual basis.
