Science Advances, 17 April 24
Researchers have identified a new positive feedback loop that intensifies ice shelf loss, suggesting that the West Antarctic Ice Sheet is more vulnerable to temperature rise than previously expected. The feedback loop is self-reinforcing: increased ice shelf melting produces more freshwater, strengthening the undercurrent transporting warm water toward the ice shelves from further offshore. If current emissions continue, this cycle will grow stronger over time; and further destabilize West Antarctica as warm waters increasingly fill the cavities under ice shelves.
