Which consequence results when glacial melt destabilizes permafrost earthflows bordering thermokarst lakes?

💡 Explanation

Increased methane ebullition occurs because permafrost thaw allows decomposition; the mechanism is microbial methanogenesis; therefore more methane is released from the lake sediment rather than less heat flux occurring.
