One Antarctic glacier could soon lose mass at the same rate as the entire continent

Mass loss from the Thwaites Glacier in West Antarctica is already accelerating – and new simulations suggest that it could be shedding 180–200 billion tonnes of ice per year within 50 years. But the study points to something more consequential: the most severe future may depend not only on what the glacier does but on whether scientists train their models in ways that enable them to see it.
