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 co

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 ...

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.

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 and

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?

Landscape partitioning and burial processes of soil organic carbon in contrasting areas of continuous permafrost

Recent studies have shown that permafrost soils in the northern circumpolar region store almost twice as much carbon as the atmosphere. Since soil organic carbon (SOC) pools have large regional and

A permafrost glacial hypothesis to explain atmospheric CO 2 and the ice ages during the Pleistocene

tion of increased oceanic carbon storage during glacials. Here we present results from the first permafrost loess sequence in Siberia spanning two glacial cycles (∼240 ka), which reveal that

Palaeoclimate: Enigmatic Earth

Global warming 55 million years ago was accompanied by a massive injection of carbon into the ocean-atmosphere system, but the resulting climatic warming was much greater than expected from the

Geomorphological controls over carbon distribution in permafrost soils: the case of the Narsajuaq river valley, Nunavik (Canada)

Soils in the northern circumpolar region play a central role in the global carbon cycle because the release of carbon through permafrost thaw and geomorphological disturbances can potentially cause...



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 to

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, the

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 present

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/16O

A projection of severe near‐surface permafrost degradation during the 21st century

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 treatment of
