Fig. 2: Response of Petermann Glacier Ice Shelf to future climate warming and subsequent cooling pathways.
From: Petermann ice shelf may not recover after a future breakup
Evolution of Petermann’s a ice-shelf calving front, b grounding line and c grounding-line flux, for the forcings compared in Fig. 1 during the 2 °C ocean warming19 and recovery experiments. An ocean cooling alone does not lead to recovery, neither does ocean cooling + increased surface mass balance (SMB). In contrast, an ocean cooling and reduced calving allow the ice shelf to recover. In c, the dashed line represents the present-day observed flux36. The labels (1b–1f) refer to the panels in Fig. 1. Modelled glacier geometries and schematic ocean temperatures are shown in a for each associated state.
