Which outcome occurs when permafrost thaw accelerates due to increased global temperatures?

💡 Explanation

When permafrost thaws, the active layer above becomes saturated and unstable because the impermeable permafrost prevents drainage, promoting solifluction which involves slow downslope movement of saturated soil. Therefore lobe formation accelerates, rather than reduced erosion, increased albedo, or decreased methane, which would require reverse temperature effects.
