Sentences with phrase «as ice shelf collapse»

As ice shelves collapse the glaciers behind them retreat more quickly, causing further sea - level rise.

Not exact matches

Just as Larsen A underwent its now notorious collapse, the Prince Gustav ice shelf, 60 kilometers to the north, also vanished.

But as the chain of ice shelf collapse pushes farther south from the peninsula's tip toward the mainland, to Larsen B and Scar Inlet, it is now entering the ominous realm of historical anomaly.

All told, as warm summers have reached farther down from the bottom of South America into the northernmost section of the Antarctic Peninsula, four ice shelves on the eastern side of the peninsula, including Larsen A, have collapsed in a striking pattern from the northern tip southward toward the Antarctic mainland.

The AMIGOS on Flask and Leppard will show how the glaciers speed up as the ice shelf holding them back collapses.

As part of her doctorate research, she has developed mathematical models to calculate when and where the ice shelf may collapse.

All told, if the eastern and western Antarctic ice shelves were to melt completely, they would raise sea levels by as much as 230 feet (70 meters); the collapse of smaller shelves like Larsen B has sped up the flow of glaciers behind them into the sea, contributing to the creeping up of high tide levels around the world.

When these ice shelves suddenly splinter and weaken or even collapse entirely, as has been observed in Antarctica, the glaciers that feed them speed up, dumping more ice into the ocean and raising global sea levels.

The data they gather will set scientists up with a solid baseline to monitor future changes and predict what comes next as Antarctica's floating ice shelves retreat and even collapse due to climate change.

Scientists recognized that climate change is rapidly altering the landscape in Antarctica, particularly when it comes to glacier retreat and ice shelf collapse, so they made a pact for how they would approach research as huge chunks of ice broke off.

For example, some exciting work being done by David Pollard and Rob DeConto suggests that processes such as ice - cliff collapse and ice - shelf hydrofracturing may play important roles in future ice sheet behavior that have not been well incorporated into most ice sheet models.

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].

The planet as a whole has heated up by about 1.3 °F since 1900, but on the peninsula, it has shot up by a whopping 5 ° in just 50 years, forcing massive ice shelves to disintegrate and penguin colonies to collapse.

Kuipers Munneke, P., Ligtenberg, S. R. M., Van den Broeke, M. R. & Vaughan, D. G. Firn air depletion as a precursor of Antarctic ice - shelf collapse.

Increased delivery of warm ocean water into the sub-ice shelf cavity may therefore cause not only thinning but also structural weakening of the ice shelf, perhaps, as a prelude to eventual collapse.»

These approaches, however, haven't taken into account some physical processes that can quickly increase ice sheet discharge, such as the collapse of terminal ice cliffs and the breakup of floating ice shelves caused by a process known as hydrofracturing.

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].

By examining past ice shelf collapse and projecting the next century of temperature change onto current ice shelves, Trusel and his fellow researchers found a huge difference between a business - as - usual fossil fuel emission scenario, in which ice melt may increase eight-fold, and a scenario where emissions are stabilized relatively rapidly and ice melt remains relatively linear.

Climate change signals are amplified in polar regions and indicators, such as the collapse of ice shelves and melting of sea ice, have raised public awareness of the consequences of a warming world.

Climate scientists study icebergs as they break up for clues to the processes that cause ice shelf collapse.

When the ice shelf Larsen B collapsed in 2002, the speed at which the on - land glaciers connected to it moved to the sea increased by as much as a factor of eight.

Where the ice shelves have collapsed some of the glaciers have apparently tripled their speed so on the edges there is a downward grade in spots (as evidenced from the topology map...

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.»
