The loss of significant portions of the ice shelf that retarded the seaward movement seems to be absent in certain areas and that might presage a more rapid deterioration of the glaciers there.

However, the idea is simple, and I've talked about this much in many presentations this winter: Take the amount of ice you need to get rid of from Greenland to raise sea level 2 m in the next century, reduce it by your best estimate of the amount that would be removed by surface mass balance losses, and try to push the rest out of the aggregate cross-sectional area of Greenland's marine - based outlet glaciers.

That equation says that there is only ONE forest system in the North American continent that might be species - stable — the 4 - park Banff / Glacier National area — but that is suffering from serious glacier system loss from climate.

They found that while two of the largest glaciers in that area — Kangerdlugssuaq and Helheim — contribute more to the total ice loss than any other single glaciers, the 30 or so smaller glaciers there contributed 72 percent of the total ice lost.

One of the current consequences of the loss of glaciers in the Chicago area is the heat during the summer.

SLR by 2100 is more likely to come from ice mass loss from West Antarctica (WAIS) where warm ocean currents are already melting ice at glacier mouths and attacking areas of the WAIS resting on the seabed.

The northern melting will likely add to sea level rise explains lead author, Shfaqat Abbas Khan: «If this activity in northwest Greenland continues and really accelerates some of the major glaciers in the area — like the Humboldt Glacier and the Peterman Glacier — Greenland's total ice loss could easily be increased by an additional 50 to 100 cubic kilometers (12 to 24 cubic miles) within a few years.»

In 2009, using ICESat, measurements of both Greenland and Antarctica found that dynamic thinning (ice loss resulting from accelerated glacier flow) now reached all latitudes in Greenland, and had intensified at key areas of Antarctica's grounding line.

This retreat represents a loss in glacier area that will be mapped in 2001 and 2002.

Equilibrium line - The boundary between the region on a glacier where there is a net annual loss of ice mass (ablation area) and that where there is a net annual gain (accumulation area).

Mountainous areas will face glacier retreat, reduced snow cover and winter tourism, and extensive species losses (in some areas up to 60 % under high emission scenarios by 2080).

Because of expected increases in the loss of land - based glaciers in Greenland, Antarctica and other areas, Joughin says the end - of - century figure may be closer to three feet.

And with a new picture of which glaciers contribute most to mass loss, IceBridge will be able to more effectively target areas in future campaigns, promising more and better data to add to the research community's body of knowledge.

They find that all of the glaciers receded over the 1952 - 2005 period with an average loss in surface area of about 0.19 % per year.

In Glacier National Park, North Cascades, Helm Glacier and Place Glacier frequent loss of the entire snowcover by the end of the ablation season has become commonplace (WGMS, 2005 The result is in net ablation throughout the accumulation area causing thinning of the glacier in the accumulation zone.

The pollution of its inland rivers and waters; depleting fresh water sources through melting of Himalayan glaciers and depleting groundwater; land degradation estimated at 20 % of land area, and damage to coastal and marine ecosystems with loss of 34 % of mangroves between 1950 and 2000, are other India's challenges.

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.»

Record droughts in many areas of the world, the loss of arctic sea ice — what you see is an increasing trend that is superimposed on annual variablity (no bets on what happens next year, but the five - to - ten year average in global temperatures, sea surface temperatures, ocean heat content — those will increase — and ice sheet volumes, tropical glacier volumes, sea ice extent will decrease.
