Which risk increases when thawing permafrost destabilizes infrastructure foundations?

💡 Explanation

When thawing permafrost underlies structures the freed organic material decomposition rates increase dramatically because microbial activity accelerates methane synthesis which then vents through the surface. Therefore methane release amplification through thermokarst lakes accelerates warming rather than reduced albedo, amplified oxidation, or volcanic related occurrences which result through related but distinct processes.
