Which process accelerates when thawing permafrost destabilizes organic matter near Arctic coastlines?

💡 Explanation

When thawing permafrost releases previously frozen organic matter, anaerobic decomposition by microorganisms increases because oxygen becomes limited, leading to the production and release of methane, a potent greenhouse gas. Therefore methane production is accelerated, rather than the silicate weathering, ozone depletion, or albedo increase which involve different mechanisms.
