Antarctic meltwater lakes threaten sea levels: study

Antarctic meltwater lakes threaten sea levels: studyAntarctic meltwater lakes are far more common than once thought and could destabilise glaciers, potentially lifting sea levels by metres as global warming sets in, scientists said Wednesday. Most vulnerable are the massive, floating ice shelves that ring the Antarctic continent and help prevent inland glaciers from sliding toward the sea, they reported in the journal Nature. Antarctica holds enough frozen water to push up global oceans by tens of metres.
