Why Thermokarst Lakes Accelerate Permafrost Carbon Release
Quick fact
Thermokarst lakes can increase permafrost carbon release by 2-3 times compared to gradual thawing alone, primarily by rapidly exposing deep organic soils to microbial decomposition.
Why this is interesting
Imagine a frozen vault holding ancient carbon for thousands of years. What happens when the vault not only defrosts but unexpectedly collapses into a pool of water—and then starts emitting greenhouse gases at an alarming rate?
