The team's next steps include looking more closely at specific ocean swell events and sea ice conditions during known ice shelf collapses and large iceberg calving events.

Scientists have spotted the mortal wound that could prompt the collapse of Antarctica's fourth - largest ice shelf.

Two years ago, Antarctica's Larsen B ice shelf collapsed over the course of 35 days; 3,250 square kilometers of shelf area — an area larger than that of Rhode Island — disintegrated.

After large icebergs broke away from nearby ice shelves in recent decades, they collapsed and the land ice they were buttressing tumbled into the sea.

Larsen B collapsed shortly after its major calving event while the Wilkins ice shelf has continued to shed large chunks of ice since 2008.

Ice shelf collapse and glacier recession here, in front of the large ice streams such as Pine Island Glacier and Thwaites Glacier, would have potential to raise sea levels by tens of centimetres to a metre, through the process of marine ice sheet instabilityIce shelf collapse and glacier recession here, in front of the large ice streams such as Pine Island Glacier and Thwaites Glacier, would have potential to raise sea levels by tens of centimetres to a metre, through the process of marine ice sheet instabilityice streams such as Pine Island Glacier and Thwaites Glacier, would have potential to raise sea levels by tens of centimetres to a metre, through the process of marine ice sheet instabilityice sheet instability23.

Sea level rise due to ice shelf collapse is as yet limited, but large ice shelves surrounding some of the major Antarctic glaciers could be at risk, and their collapse would result in a significant sea level rise contribution [22].

It is well known that ice shelves on the Antarctic Peninsula have collapsed on several occasions in the last couple of decades, that ice shelves in West Antarctica are thinning rapidly, and that the large outlet glaciers that drain the West Antarctic ice sheet (WAIS) are accelerating.

Large floating ice shelves had formed in the Ross Sea and Weddell Sea marine embayments after WAIS had collapsed in those sectors after the LGM, and I had concluded that these ice shelves, being confined and pinned at places to the sea floor, were now buttressing these sectors of WAIS, preventing further collapse.

Some mechanisms for that are hypothesized, e.g. methane release from polar regions, increased melting of Greenland leading to stopping the Gulf Stream, rapid reduction of Arctic sea - ice and its positive feedback, collapse of Antarctic ice shelves, loss of the Amazon, large volcanoes, asteroid impacts, unexpected solar variation.

The regional climate change now occurring in West Antarctica is a pressing concern as collapsing ice shelves, like those on the Antarctic Peninsula, could lead to a larger rise of several tens of centimeters in this century [IPCC, 2013].

What's wrong with the Filchner Shelf largest ever measured 331 km by 97 km 31,000 km2 ice shelf collapse «The largest iceberg ever spotted was sighted by the USS Glacier on November 12, 1956 ″.

In 2002, the Larsen B ice shelf collapsed; in 2003, the World Glacial Monitoring Service reported that «The recent increase in the rates of ice loss over reduced glacier surface areas as compared with earlier losses related to larger surface areas (cf. the thorough revision of available data by Dyurgerov, 2002) becomes even more pronounced and leaves no doubt about the accelerating change in climatic conditions.»

A larger part of Antarctica appears to be warming than was apparent at the time of the AR4 report (10) and, while not necessarily indicative of destabilization of grounded ice, the Wilkins ice shelf now appears ready to collapse in entirety (11).»
