Climate warming will thaw permafrost, releasing trapped carbon from this high-latitude reservoir and further exacerbating global warming. 
Economic impacts of carbon dioxide and methane released from thawing permafrost
The economic impact of carbon dioxide and methane release from thawing Arctic permafrost due to global warming could be enormous unless action is taken to minimize the scale of the release.
Cryogenic soil processes in a changing climate
A considerable part of the global pool of terrestrial carbon is stored in high latitude soils. In these soils, repeated cycles of freezing and thawing creates soil motion (cryoturbation) that in coExpand
Greenhouse gas production in low-latitude lake sediments responds strongly to warming
Inland water sediments receive large quantities of terrestrial organic matter and are globally important sites for organic carbon preservation. Sediment organic matter mineralization is positively ...
Hot trends and impact in permafrost science
An increased interest in Arctic environments, mainly due to climate change, has changed the conditions for permafrost research in recent years. This change has been accompanied by a global increaseExpand
High‐resolution mapping of ecosystem carbon storage and potential effects of permafrost thaw in periglacial terrain, European Russian Arctic
This study describes detailed partitioning of phytomass carbon (C) and soil organic carbon (SOC) for four study areas in discontinuous permafrost terrain, Northeast European Russia. The mean abovegExpand
Impacts of Global Warming on Biogeochemical Cycles in Natural Waters
The main source of energy that drives the dynamics of Earth’s outer spheres, including its climate, is unquestionably the Sun.
Long‐Term Measurements of Methane Ebullition From Thaw Ponds
Arctic regions are experiencing rapid warming, leading to permafrost thaw and formation of numerous water bodies. Although small ponds in particular are considered hot spots for methane (CH4) releaExpand
The role of inland waters in the carbon cycle at high latitudes
Understanding the drivers of climate change requires knowledge about the global carbon (C) cycle. Although inland waters play an important role in the C cycle by emitting and burying C, streams andExpand
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 ...
Carbon cycle: A warm response by soils
The flux of carbon from soils to the atmosphere has apparently increased with climate warming. But does this reflect a net loss of carbon to the atmosphere that could exacerbate climate change?


A projection of severe near‐surface permafrost degradation during the 21st century
[1] The current distribution and future projections of permafrost are examined in a fully coupled global climate model, the Community Climate System Model, version 3 (CCSM3) with explicit treatmentExpand
Carbon-biosphere-climate interactions in the last glacial maximum climate
The total carbon inventory in the terrestrial biosphere in the last glacial maximum (LGM), 18 kyr ago, is analyzed in a series of experiments that examine the sensitivity of the inventory toExpand
Glacial-interglacial atmospheric CO2 change —The glacial burial hypothesis

Organic carbon buried under the great ice sheets of the Northern Hemisphere is suggested to be the missing link in the atmospheric CO2 change over the glacial-interglacial cycles. At glaciation, theExpand
Increases in terrestrial carbon storage from the Last Glacial Maximum to the present
EVIDENCE from ice cores1 indicates that concentrations of atmospheric carbon dioxide were lower by about 75 p.p.m. during the Last Glacial Maximum (LGM; ∼18,000 years ago) than during the presentExpand
Effect of seawater carbonate concentration on foraminiferal carbon and oxygen isotopes
Stable oxygen and carbon isotope measurements on biogenic calcite and aragonite have become standard tools for reconstructing past oceanographic and climatic change. In aquatic organisms, 18O/16OExpand
New insights into the Weichselian environment and climate of the East Siberian Arctic, derived from fossil insects, plants, and mammals
Multidisciplinary study of a key section on the Laptev Sea Coast (Bykovsky Peninsula, east Lena Delta) in 1998–2001 provides the most complete record of Middle and Late Weichselian environments inExpand
