A huge amount of carbon (C) is stored in permafrost regions. Climate warming and
permafrost degradation induce gradual and abrupt carbon emissions into both the …

Permafrost soils in the high northern latitudes contain a substantial amount of carbon which
is not decomposed due to frozen conditions. Climate change will lead to a thawing of at least …

Thawing permafrost and the resulting microbial decomposition of previously frozen organic
carbon (C) is one of the most significant potential feedbacks from terrestrial ecosystems to …

• Northern permafrost region soils contain 1,460-1,600 billion metric tons of organic carbon,
about twice as much as currently contained in the atmosphere.• This pool of organic carbon …

Permafrost soils contain enormous amounts of organic carbon, which could act as a positive
feedback to global climate change due to enhanced respiration rates with warming. We …

Recent observations suggest that permafrost thaw may create two completely different soil
environments: aerobic in relatively well‐drained uplands and anaerobic in poorly drained …

Climate warming affects permafrost soil carbon pools in two opposing ways: enhanced
vegetation growth leads to higher carbon inputs to the soil, whereas permafrost melting …

The thawand release of carbon currently frozen in permafrost will increase atmospheric CO2
concentrations and amplify surface warming to initiate a positive permafrost carbon …

Large quantities of organic carbon are stored in frozen soils (permafrost) within Arctic and
sub-Arctic regions. A warming climate can induce environmental changes that accelerate …

Significant progress in permafrost carbon science made over the past decades include the
identification of vast permafrost carbon stocks, the development of new pan‐Arctic …
