Which consequence arises when construction destabilizes Arctic permafrost?

💡 Explanation

Increased thaw from construction induces solifluction: the gradual downslope movement of water-saturated soil, because the loss of ice-cement causes reduced shear strength and lubrication. Therefore, infrastructure buckles, rather than terrain becoming stabilizated by reduced erosion or increased albedo.
