Not exact matches

Also in the mid-1990s, another group of scientists proposed the now widely accepted mechanism for how lakes can form under glaciers: Heat radiating from Earth's interior is trapped under the thick, insulating ice sheet, and pressure from the weight of all the ice above it lowers the melting point of the ice at the bottom.

The glacier is currently experiencing significant acceleration, thinning and retreat that is thought to be caused by «ocean - driven» melting; an increase in warm ocean water finding its way under the ice shelf.

The climate change and melting [of glaciers and polar ice] issue is obviously something that's apparently under way and can not be turned on a dime.

These shifts may include rising sea levels, stronger tropical cyclones, the loss of soil moisture under higher temperatures, more intense precipitation and flooding, more frequent droughts, the melting of glaciers and the changing seasonality of snowmelt.

Understanding how layers of air insulate the surface of glaciers, for example, is vital to making accurate estimates of how fast they will melt — and sea levels will rise — as the Earth warms under its blanket of greenhouse gases.

I suppose that as the under side of the glacier melts, the resulting fresh water mixes with the adjacent salt water, making it lighter and causing it to flow upwards along the under side of the ice.

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

The estimates are quite variable because of the difficulty in measuring these things in a difficult part of the world and the complexity of the processes (ice berg calving; under ice shelve melting, snow blowing, under glacier melt etc.).

Under the right circumstances glaciers melt abruptly, regional forests and soil become carbon emitters abruptly, and oceanic / atmospheric currents shift abruptly, leading to rapid global warming.

A long terms study of a glacier draining the Grimsvotn volcano under the Vatnojokull Ice Cap indicate that there is an initial acceleration due to increased basal melt water pressure, as the flux increasing from the activity.

[Response: A little postscript: Glaciers reappearing where Amsterdam is now, or Greenland melting and Amsterdam disappearing under the sea, would actually be equally bad.

As glaciers in the Himalayas melt faster due to global warming, pollutants buried under them are finding their way down to the north Indian plains.

Warm ocean water plays a significant role in melting glacial ice from below, and a better mapping of Antarctica's and Greenland's landforms beneath the ice suggests that ocean melting of the glacier fronts may play a more significant role than previously thought as the ice sheets retreat (under a global warming scenario).

Shifting currents, increased freshwater input from melting sea ice and glaciers, and changes in upper and lower sea - level circulation patterns are already occurring, and they'll progress rapidly if anthropogenic greenhouse gas emission continues under a business - as - usual scenario.

The source document, the Intergovernmental Panel on Climate Change (IPCC) 2007 Fourth Assessment Report (AR4), has been under harsh scrutiny over the past weeks for a number of blunders, including the Climategate scandal, bogus claims about Himalayan glacier melt, false assertions The Netherlands are drowning, deceptive hysteria over conditions in the Amazon, exaggerations of vanishing polar ice caps, and fraudulent cover - up of Chinese temperature data.

It could take decades or centuries, but change will be locked in by a 3C temperature rise, which would extensively melt ice caps, shrink glaciers and thermally expand the oceans so many current coastlines and low - lying plains would be under sea level.

As much as 70 percent of the ice within the great Himalayan glaciers could melt out by 2100 under business as usual fossil fuel burning.

The Polar bears stubbornly refuse to go extinct, indeed the buggers are thriving, the glaciers don't appear to be disappearing, sea levels have stayed boringly level, we haven't been subsumed by hordes of desperate climate refugees, the polar ice caps haven't melted, the Great Barrier Reef is still with us, we haven't fought any resource wars, oil hasn't run out, the seas insist on not getting acidic, the rainforest is still around, islands have not sunk under the sea, the ozone holes haven't got bigger, the world hasn't entered a new ice age, acid rain appears to have fallen somewhere that can't quite be located, the Gulf Stream hasn't stopped, extreme weather events have been embarrassingly sparse in recent years and guess what?

The rise was caused partly by the simple thermal expansion of sea water under the influence of global warming, and increasingly by the melting of glaciers and ice sheets.

And all that time, the temperatures will rise, the glaciers will melt, the sea levels will rise, and we'll be that much deeper into a catastrophe that is already well under way.

Unprecedented melting of alpine glaciers has exposed bodies and huts under the postulated eternal, absent anthropogenic CO2, glaciers.

34 Temperatures Rising due to Global Warming Effects Glaciers melting Greenland — If all of the ice melts, oceans will rise 23 feet Antarctic — major reduction in ice coverage Permafrost in Tundra is releasing CO2 that is stored under the ice

Chloride = 31,000 p.p.m. (de-icing agents) trapped under the ice, is causing the bottom of the ice shelf to thaw, resulting in continuous thinning and acceleration of glacial melt (under water glacier cutting).
