Sentences with phrase «ice collapse processes»

Not exact matches

«Ice - cliff collapse has been debated as a theoretical process that might cause West Antarctic Ice Sheet retreat to accelerate in the future,» said co-author Dr Robert Larter, from the British Antarctic Survey.

His theoretical work focuses on the formation of binary and multiple stars, triggered collapse of the presolar cloud that eventually made the Solar System, mixing and transport processes in protoplanetary disks, and the formation of gas giant and ice giant protoplanets.

Because air motions in these clouds are driven primarily by processes tied to the presence of liquid, when water droplets competing for water vapor lose to ice crystals, an ensuing chain of events drives the cloud toward collapse.

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.

This process is difficult to accurately model, but rapid ice sheet collapse would certainly result in dramatically higher rates of sea level rise once this critical threshold is passed.

It's important to remember that the processes involved in coastal erosion and ice - shelf collapse are very different!

But it appears far more likely that a better understanding of these processes will act to revised our estimates of ice sheet collapse timescales downward, rather than upward.

, «CO2 as control knob», and opening paragraphs invoking CO2 indicate he's more concerned with CO2 than the actual processes of ice collapse.

More recent research, however, suggests that collapse could happen sooner; processes such as ice cliff failure and hydrofracture, omitted from most ice - flow models, might initiate a collapse of the Thwaites Glacier within a few decades (DeConto and Pollard 2016, Scambos et al. 2017).

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.

For example, a recent ice sheet model sensitivity study finds that incorporating the physical processes of hydrofracturing of ice and ice cliff failure increases their calculated sea level rise from 2 meters to 17 meters and reduces the potential time for West Antarctic collapse to decadal time scales.

Slate's Phil Plait was responsibly reserved in his coverage, emphasizing that although one of the press releases used the word «collapse,» the melting of this particular glacier — which by itself contains enough ice to raise global seas by three feet — is a process that will take centuries, if not longer, to play out.

The evolution of this drainage system almost certainly governs the process of ice - sheet collapse (2 - 5).

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

Among the global - scale tipping points identified by earth scientists are the collapse of large ice sheets in Greenland and Antarctica, changes in ocean circulation, feedback processes by which warming triggers more warming, and the acidification of the ocean.h

However, given the acknowledged (12) lack of processes that could accelerate collapse in current models, and their inability to simulate the rapid disappearance of continental ice at the end of the last ice age, a lower limit of 300 years is conceivable (34).

Two teams of scientists say the long - feared collapse of the West Antarctic Ice Sheet has begun, kicking off what they say will be a centuries - long, «unstoppable» process that could raise sea levels by as much as 15 feet.
