Simulated last deglaciation of the Barents Sea Ice Sheet primarily driven by oceanic conditions

“…Several recent studies show that over the last decades marine-terminating glaciers and ice shelves of the WAIS are rapidly retreating (Cook et al, 2016;Rignot et al, 2013) and thinning (Paolo et al, 2015), primarily due to the intrusion of relatively warm Circumpolar Deep Water in the cavities underneath the ice-shelves and close to the grounding zone (Rignot et al, 2013;Pritchard et al, 2012;Schmidtko et al, 2014;Khazendar et al, 2016), although there is also evidence in favor of surface warming (Rebesco et al, 2014a). However, to what extent ice-shelf thinning or collapse might trigger sustained grounded ice discharge into the ocean remains highly uncertain, precluding well-constrained future projections of the WAIS contribution to future global-mean sea level rise (Edwards et al, 2019;Colleoni et al, 2018).…”

“…However, the use of existing parametrisations to represent these feedbacks in ice sheet model simulations is still debated, as it might lead to an overestimated ice sheet response to ocean warming (Gudmundsson et al, 2012;Petrini et al, 2018;Edwards et al, 2019). Direct measurements of the dynamic response of the WAIS to ocean warming are difficult to acquire because of the large spatio-temporal scale of glaciological changes (Colleoni et al, 2018). A valid alternative to fulfil this knowledge gap is to look at evidence of past ice sheet retreats both in the Northern and Southern Hemisphere.…”
