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

💡 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.
