Abrupt permafrost thaw mobilizes ancient organic matter, which could fuel further warming, yet its fate remains uncertain. We studied thaw slumps in Arctic Canada using thermal, radiocarbon, and molecular analyses.
Recently thawed debris and runoff exiting the slumps contained old, thermally stable organic matter, compositionally similar to surrounding permafrost. This suggests that much of the thaw-mobilised carbon survives initial transport and may be processed or sequestered downstream…
