Which risk increases on steep, saturated Arctic slopes undergoing seasonal thaw and solifluction?

A)Increased methane emissions from thaw

B)Enhanced carbon sequestration in soils

C)Reduced biodiversity from thermokarst lakes

D)Accelerated infrastructure damage from creep✓

💡 Explanation

When thaw occurs in permafrost regions experiencing solifluction, the active layer becomes saturated causing soil to slowly flow downslope deforming structures due to creep. Therefore infrastructure damage increases, rather than methane emissions, carbon sequestration, or thermokarst lake formation which are driven by different processes.
