Researchers studying ‘doomsday glacier’ make worrying discovery

(NEXSTAR) – Antarctica’s “doomsday glacier,” referred to as such for its potential to dramatically raise global sea levels, is melting faster than we thought thanks to warmer sea water passing below it, according to a new study.

The researchers, led by glaciologists with the University of California, Irvine (UCI), said in a study published Monday in the Proceedings of the National Academy of Sciences that the Thwaites Glacier may be breaking apart “much faster” than previously believed.

Using satellites and a technique called radar interferometry to track changes in surface elevation, the team found that the glacier appeared to be lifting several centimeters as pressurized tide water moved below the glacier across many miles, further inland than previously thought.

Warmer seawater working its way under the glacier may help explain the “rapid, past, and present changes in ice sheet mass and the slower changes replicated by ice sheet models,” the study noted, adding that the pressurized seawater will create a “vigorous melt” that will further imperil the glacier.
