Permafrost carbon cycle to the atmosphere. Carbon stored within arctic soils and permafrost is susceptible to release due to several different mechanisms. Carbon that is stored in permafrost is released back into the atmosphere as either carbon dioxide (CO) or methane (CH). Aerobic respiration releases carbon dioxide, while anaerobic respiration releases methane. Carbon is continually cycling between soils, vegetation, and the atmosphere. Currently, carbon flux from permafrost soils is minimal, however studies suggest that future warming and permafrost degradation will increase the CO flux from the soils. Thaw deepens the active layer, exposing old carbon that has been in storage for decades, to
