These changes destroy habitats for plants and animals adapted to the frozen conditions. The sudden collapse of ground surfaces can also create vents, releasing concentrated plumes of the gas.
Organic Carbon Storage and Methane Release in Permafrost Regions
This geological trapping mechanism has kept the gas contained for thousands of years. The ground loses its structural integrity, leading to erosion, landslides, and the formation of thermokarst lakes.
As the gas enters the atmosphere, it exacerbates the greenhouse effect, leading to further global warming, which in turn causes more permafrost to thaw. Plant and animal matter falls to the ground in cold regions where decomposition is slow.
Organic Carbon Storage and Methane Release in Permafrost Regions
Formation and Storage Mechanisms The accumulation of methane in permafrost occurs over millennia. As the ground becomes saturated and unfrozen, microbial activity surges, accelerating the conversion of organic carbon into methane and carbon dioxide.
