Why care about warming effects on soil respiration under permafrost collapse? Permafrost-affected regions stored large quantities of soil organic carbon (C), with an amount of 1014~1672 Pg C (1 Pg = 1015 g).

AbstractAs global temperatures continue to rise, a key uncertainty of terrestrial carbon (C)–climate feedback is the rate of C loss upon abrupt permafrost thaw. This type of thawing—termed thermokarst—may in turn accelerate or dampen the response of microbial degradation of soil organic matter and carbon dioxide (CO2) release to climate warming. However, such impacts have not yet been explored in experimental studies.
