Models warn Thwaites Glacier could rival entire Antarctic ice loss by 2067

The future of one of Antarctica's most iconic glaciers could be far more dramatic than scientists previously thought. Using satellite calibrated ice sheet models, a team of researchers from the University of Edinburgh found that the Thwaites Glacier in West Antarctica could be shedding 180–200 gigatonnes of ice per year by 2067—a rate roughly comparable to the entire Antarctic ice sheet's current mass loss. That would represent a stunning acceleration in ice loss from a single glacier and underlines urgent concerns about future contributions to sea level rise.
