Which risk increases when thermal erosion degrades permafrost?

💡 Explanation

Methane release increases because thermal erosion causes permafrost thaw, leading to clathrate destabilization which contains significant methane reserves. Therefore methane is emitted, rather than bedrock increase albedo which would imply different surface changes.
