Since so much of the ice sheet is grounded underwater, rising sea levels may have the effect of lifting the sheets, allowing more - and increasingly warmer - water underneath it, leading to further bottom melting, more ice shelf disintegration, accelerated glacial flow, and further sea level rise, and so on and on, another vicious cycle.
During the last glacial maximum, Wiens explained, the weight of the ice bent the Earth's crust, forcing the plastic rock in the upper layer of the Earth's mantle to flow away from the loaded region.
The causes of ice ages remain controversial for both the large - scale ice age periods and the smaller ebb and flow of glacial — interglacial periods within an ice age.

Also, there is some evidence that what happens at the front of such glaciers can affect the «back» (inland) parts of the glaciers increasing glacial flow toward the ocean.
This accelerates the glacial flow and the calving of icebergs into the surrounding ocean.
But without the ice shelves to impede the flow of glacial ice, typically moving 400 — 900 meters a year, the flow of ice from the continent could accelerate, leading to a thinning of the ice sheet on the edges of the Antarctic continent.
In the Andes, glacial melt water supports river flow and water supply for tens of millions of people during the long dry season.
Any precipitation or glacial meltwater flowing into an endorheic basin could require centuries to thousands of years to flow back to the oceans.
Looking at these glacial flows individual contributions to overall mean sea level rise (MSLR) and talking in terms of decades to centuries for their collapse makes the problem seem very far off in human terms.
Since glacial ice deforms like very slow putty, the steepening of the glacier would have caused the more mobile, middle section to flow pick up speed.
And study authors found that 2 C to 5 C warming of local ocean waters with somewhat greater local air temperature increases was capable of flooding these basins in stages — forcing Totten's glacial ice to flow out into the Southern Ocean and provide significant contributions to sea level rise.

Climate News Network: Researchers in the US have identified a new reason for the acceleration in the melting of Greenland's icecap − the ice underneath, as it melts and then refreezes, appears to speed up glacial flow.
Glacial melt contributes as much as half of the region's flow (41, 42).
Part of the water flow in these river basins depends on snow and glacial melt to perennial rivers, such as the Ganges, Indus, Brahmaputra, Mekong and Yangtze (9).

The glaciers flowing from the steep mountains on the tip of the South American continent, have been one of the most visible of global glacial retreats.
So, I'm not extremely versed with glacial ice, but what we're talking about is sheathing of ice because of ice flow, not melting, correct?
But a new discussion paper, «The role of glaciers in stream flow from the Nepal Himalaya,» (Alford and Armstrong, The Cryosphere Discuss., 4, 469 - 494, 2010) concludes that glacial runoff contributes only about 4 % to the total annual stream flow of the Ganges system; the great majority is contributed by monsoon rains.
Higher elevation areas could experience altered water flow in some river basins if current rates of glacial retreat continue, but shifts in the location, intensity, and variability of rain and snow due to climate change will likely have a greater impact on regional water supplies.
The observed effects of cryosphere reduction include modification of river regimes due to enhanced glacial melt, snowmelt advance and enhanced winter base flow; formation of thermokarst terrain and disappearance of surface lakes in thawing permafrost; decrease in potential travel days of vehicles over frozen roads in the Arctic; enhanced potential for glacier hazards and slope instability due to mechanical weakening driven by ice and permafrost melting; regional ocean freshening; sea - level rise due to glacier and ice sheet shrinkage; biotic colonisation and faunal changes in deglaciated terrain; changes in freshwater and marine ecosystems affected by lake - ice and sea - ice reduction; changes in livelihoods; reduced tourism activities related to skiing, ice climbing and scenic activities in cryospheric areas affected by degradation; and increased ease of ship transportation in the Arctic.
Other factors being investigated are the impact of lakes on Greenland's glacial surfaces, the effect of dust and soot on the ice sheet (which have been shown to have a major impact in accelerating melting in Himalayan glaciers), and how surface meltwater affects ice flow into the ocean (previous research has shown that is speeds it and is increased by short term weather extremes).
This means that atmospheric warming can reach thousands of metres below the ice sheet − warming the glacial base and potentially increasing its rate of flow.
