Aug 21, 2024 · They predicted that if tall ice cliffs become exposed in Antarctica or Greenland by the rapid disintegration of floating ice shelves, they could drive glacier retreat into the thicker …

May 11, 2021 · Marine ice-cliff instability could accelerate ice loss from Antarctica, and according to some model predictions could potentially contribute >1 m of global mean sea level rise by …

May 6, 2021 · Ice cliffs are exposed at marine-terminating glaciers (glaciers that meet the ocean) following the loss of ice shelves that extend over the adjacent ocean column. Crucially, ice …

Nov 16, 2022 · In Antarctica, these magnificent cliffs collar the edges of the ice sheet. Paired with floating ice shelves, they hold in all the ice sitting in the middle of the continent like a cork that …

Jun 18, 2021 · Here we use a model that resolves flow and failure of ice to show that dynamic thinning can slow or stabilize cliff retreat, but when ice thickness increases rapidly upstream …

May 13, 2021 · Ice cliffs are exposed at marine-terminating glaciers (glaciers that meet the ocean) following the loss of ice shelves that extend over the adjacent ocean column. Crucially, ice …

Oct 21, 2019 · The marine ice cliff instability hypothesis posits that cliffs taller than a critical height (~90 m) will undergo structural collapse, initiating runaway retreat in ice-sheet models. This …

May 25, 2021 · Direct observations at the grounding zone of a tidewater glacier ice cliff in the Weddell Sea, obtained by remotely operated vehicle, reveal evidence for a freeze-on of …

Aug 21, 2024 · For almost a decade, climate scientists have been trying to get their heads around a particularly disastrous scenario for how West Antarctica’s gigantic ice sheet might break …

Jun 18, 2021 · For the majority of thickness gradients considered, faster-flowing ice allows ice margins to advance, whereas slower-flowing ice produces cliff retreat. Where ice thickness …
