Reframing the dangers Antarctica's meltwater ponds pose to ice shelves and sea level
dangers Antarctica meltwater ponds pose ice shelves sea level
2019/11/15
Dangers to ancient Antarctic ice portend a future of rapidly rising seas, but a new study, partially funded by NSF, may relieve one nagging fear. Meltwater ponds fracturing the ice below them may not ...

Instability Antarctic ice projected worst-case sea level rise
2019/10/23
Images of vanishing Arctic ice are jarring, but the region’s potential contributions to sea level rise are no match for Antarctica’s. Now, a study says that instability hidden in Antarctic ice increas...
