Antarctic ice-shelf basal melt shaped by competing feedbacks (opens in new tab)

Antarctic ice-shelf melt constitutes a major source of epistemic uncertainty in future sea level rise, yet the interplay between melt and ocean circulation is not captured in climate model projections. Consequently, the relative importance of feedbacks from increased ice-shelf melting versus directly forced ocean change is poorly understood. Here we examine how externally forced changes and melt-driven feedbacks each influence the continental-shelf response to future climate change, using a c...
