Which risk increases when a warming climate thaws discontinuous permafrost beneath taiga forest?

💡 Explanation

When discontinuous permafrost thaws, microbial decomposition of previously frozen organic matter accelerates because anaerobic conditions prevail in newly formed thermokarst lakes, releasing significant methane. Therefore increased methane release develops, rather than cooling, weathering, or reduced erosion, which involve alternative climate processes acting under different conditions.
