The permafrost zone is expected to be a substantial carbon source to the atmosphere, yet
large-scale models currently only simulate gradual changes in seasonally thawed soil …

Permafrost carbon feedback (PCF) modeling has focused on gradual thaw of near-surface
permafrost leading to enhanced carbon dioxide and methane emissions that accelerate …

Increasing temperatures in northern high latitudes are causing permafrost to thaw, making
large amounts of previously frozen organic matter vulnerable to microbial decomposition …

The fate of currently frozen permafrost carbon as high-latitude climate warms remains highly
uncertain and existing models give widely varying estimates of the permafrost carbon …

Abstract Models predict that thaw of permafrost soils at northern high latitudes will release
tens of billions of tonnes of carbon (C) to the atmosphere by 2100 (refs,,). The effect on the …

Permafrost soils contain an estimated 1,700 Pg of carbon, almost twice the present
atmospheric carbon pool. As permafrost soils thaw owing to climate warming, respiration of …

Methane emissions regulate the near‐term global warming potential of permafrost thaw,
particularly where loss of ice‐rich permafrost converts forest and tundra into wetlands …

Permafrost thaw can accelerate climate warming by releasing carbon from previously frozen
soil in the form of greenhouse gases. Rainfall extremes have been proposed to increase …

Thawing of permafrost and the associated release of carbon constitutes a positive feedback
in the climate system, elevating the effect of anthropogenic GHG emissions on global-mean …
