Which landscape change accelerates when permafrost thaw increases earthworm bioturbation?

💡 Explanation

Increased bioturbation from earthworms mixes newly thawed, previously frozen organic matter, promoting methanogenesis because anaerobic decomposition is enhanced under saturated conditions; therefore methane release increases, rather than cryoturbation, albedo changes, or glacial abrasion dominating.
