A study published in 2011 by Scambos, Truffer and Pettit found that one glacier continues to accelerate even 15 years after losing its ice shelf: Röhss Glacier (which used to flow into the Prince Gustav ice shelf) has now reached nine times its former speed.
Today, as warming waters caused by climate change flow underneath the floating ice shelves in Pine Island Bay, the Antarctic Ice Sheet is once again at risk of losing mass from rapidly retreating glaciers.

New data show ice shelves are collectively losing 100 billion tons of ice per year, and glaciers have accelerated by up to 70 percent.
And she describes sobering trends: The projection that Switzerland will lose more than half of its small glaciers in the next 25 years; the substantial retreat of glaciers from the Antarctic, Patagonia, the Himalayas, Greenland and the Arctic; the disappearance of iconic glaciers in Glacier National Park, Montana, or reduction to chunks of ice that no longer move (by definition, a glacier must be massive enough to move).
While the Alps could lose anything between 75 percent and 90 percent of their glacial ice by the end of the century, Greenland's glaciers — which have the potential to raise global sea levels by up to 20 feet — are expected to melt faster as their exposure to warm ocean water increases.
The Greenland, and possibly the Antarctic, ice sheets have been losing mass recently, because losses by ablation including outlet glaciers exceed accumulation of snowfall.
As glaciers and ice caps melt, Louisiana is losing land to the sea and barrier islands are gradually slipping beneath the watery surface, drowned by a slowly rising tide, a process suggested by the cover photo.
It is another «Lost City of the Incas» rediscovered officially late in 20th century located high on a ridge spur almost 1750 mts above the raging glacier - fed Apurimac River and surrounded by towering Salkantay and Humantay snow - capped peaks.
... the confusion came most likely from a confusion in definitions of what is the permanent ice sheet, and what are glaciers, with the «glaciers» being either dropped from the Atlas entirely or colored brown (instead of white)... there is simply no measure — neither thickness nor areal extent — by which Greenland can be said to have lost 15 % of its ice.
According to experts, the Jakobshavn glacier, one of Greenland's largest, is moving at a faster rate than ever before, losing 20 million tons of ice every day, equivalent to the amount of water used every year by the residents of New York City.
On average, the world's glaciers and ice caps lost enough water between 1961 and 1990 to raise global sea levels by 0.35 - 0.4 mm each year.
By early July snowpack beyond the glacier margins is limited, Snotel sites have lost their snowcover, and yet streamflow is still heavily dependent on snow and ice melt from glaciers (Fountain and Tangborn, 1985; Pelto, 1996).
The glaciers that formed the broad, flat valley surrounded by mountains — Flathead County's namesake — are losing mass and retreating as the region warms.
Just yesterday we had an example of a scientist who projected that Himalayan glaciers were losing ice at an an amazing rate correcting himself and cutting his own mass loss estimate by 30 %.
The ice sheet in West Antarctic is losing ice at a faster rate than any other part of the continent and some glaciers are receding annually by over one metre.
In the detached US state of Alaska, where climate change has propelled temperatures upwards by more than 3C in the last half century, the glaciers are melting at a staggering rate, some losing up to 1 km in thickness in the last 100 years.
If — or more likely when — Thwaites and its neighbour, the Pine Island glacier, ultimately lose all their ice, one estimate suggests that could raise global sea levels by about 3.4 m, enough to affect every coastal city on Earth.
An equilibrium response occurs when a new equilibrium is reached by a retreating glacier losing enough of its high ablating sections, usually at its lowest elevations, so that accumulation once again balances ablation.
Lost photos prove Greenland's ice was melting FASTER 80 years ago than today 80 - year - old photo plates from Danish polar explorerProve that Greenland's glaciers melted faster in 30s than they did todayBrief cooling period mid-century re-froze icePre - satellite images of ice shelves are extremely rare By Rob Waugh Published: 08:06 GMT, 30 May 2012 Updated: 11:54 GMT, 30 May 2012 The glacier named after Danish explorer Knud Rasmussen in Greenland A stash of 80 - year - old photo plates in a Danish basement has proved that Greenland's ice was melting even faster then that it is now.
Concern is raised by recent inferences from gravity measurements that the WAIS is losing mass (39), and observations that glaciers draining into the Amundsen Sea are losing 60 % more ice than they are gaining and hence contributing to sea - level rise (40).
By 2003, this glacier — already among the world's fastest - moving — reached speeds of more than 7.8 miles (12.6 kilometers) per year.2 In just one day — between July 6 and 7, 2010 — satellite images showed that Jakobshavn Isbrae lost approximately 2.7 square miles (7 square kilometers) of ice area.6
No, because in that case the glaciers currently supported by the ice shelf will lose that support and slide into the ocean.
Global mass balance data are transformed to sea - level equivalent by first multiplying the ice thickness (meters) lost to melting by the density of ice (about 900 kilograms per cubic meter), to obtain a water equivalent thickness, and then multiplying by the surface area of these «small» glaciers (about 760,000 square kilometers).
