Which risk increases when warming temperatures accelerate thermokarst formation in Arctic permafrost regions?

💡 Explanation

When thermokarst formation accelerates, the thawing of permafrost releases previously trapped organic matter which microbial decomposition can convert to methane because anaerobic conditions predominate in saturated thaw zones, increasing atmospheric methane. Therefore methane release is the key risk, rather than decreased albedo or stabilization which require different mechanisms and initial conditions.
