Which outcome results when subsurface permafrost undergoes thawing?

💡 Explanation

Thawing permafrost releases trapped organic matter. Microbial decomposition via methanogenesis generates methane; because methane is a potent greenhouse gas, radiative forcing increases, therefore global warming accelerates rather than being mitigated by vegetation changes or albedo effects.
