Antarctic ice loss triples, boosting sea levels

Antarctica has lost a staggering three trillion tonnes of ice since 1992, according to a landmark study published Wednesday that suggests the frozen continent could redraw Earth’s coastlines if global warming continues unchecked.

Two-fifths of that ice loss occurred in the last five years, a three-fold increase in the pace at which Antarctica is shedding its kilometres-thick casing, a consortium of 84 scientists reported in the journal Nature.
