"Ice shelves provide a key source of stability to the Antarctic Ice Sheet by buttressing the flow of grounded ice. As ice shelves weaken and collapse due to rising temperatures, the glaciers buttressed by them speed up, increasing Antarctica’s contribution to sea level rise. Pine Island Glacier is the fastest flowing glacier in Antarctica and the ice shelf that buttresses it has undergone significant change in the last decade, resulting in a 20% increase in ice velocity. We compare observations to models to better understand the processes contributing to buttressing loss and conclude the Pine Island Ice Shelf has lost significant buttressing as the margins have deteriorated, destabilizing the grounding line and accelerating mass loss from West Antarctica."
