The breaking off of large chunks of ice from glaciers accelerates the melting of the Arctic ice sheet in Greenland... Greenland’s ice sheet is melting at an increasingly rapid pace ... Arctic ice sheet.
But the WestAntarctic Ice Sheet is on the verge of a 'catastrophic' collapse, scientists have warned ... If it did collapse, experts predict the West Antarctic Ice Sheet would raise sea levels by more than 9.8ft (three meters).

This Arctic expedition to the end of the earth takes months of training and could be a once-in-a-lifetime adventure, or the first of many extreme trails. So could SamanthaHerbert hack it? ... .
... the west Antarctic ice sheet is already undergoing rapid and potentially irreversible melting.The west Antarctic ice sheet contains enough ice to raise global sea levels by over three to five metres.
The event also defies our predictions of how the Greenland ice sheet evolves over time, even when taking climate change and the accelerating melting of ice sheets into consideration.
A hidden lake beneath the Greenland Ice Sheet unexpectedly drained more than a decade ago, fracturing the ice surface and forming a large crater — an event only recently uncovered by Earth-observing satellites ....
"The existence of subglacial lakes beneath the Greenland Ice Sheet is still a relatively recent discovery, and - as our study shows - there is still much we don't know about how they evolve and how they can impact on the ice sheet system.
