Which feedback loop accelerates cirque erosion under increased warming?

A)Ice-albedo amplifying insolation absorption
B)Vegetation decreasing hillslope solifluction
C)Dust deposition raising glacial albedo
D)Permafrost impeding sediment evacuation

💡 Explanation

Ice-albedo feedback warms cirques because reduced ice area lowers albedo, amplifying insolation; positive feedback elevates erosion therefore, raising temperature rather than suppressed erosion through stabilizing permafrost behavior, given an alternative climate influence.
