Not exact matches

Its goal is to find out where and how fast seawater is melting the glacial ice.

She recently worked with a biologist in Washington, for example, on a paper about how narwhals use glacial fronts in summertime — the tusked marine mammals appear to be attracted to glaciers with thick ice fronts and freshwater melt that's low in silt, though it's not yet clear why.

The abstract doesn't have the room to provide more information on how the melting of glacial ice has weakened part of the volcano, leading to an increased potential for a landslide.

As glacial geologists, some of the biggest questions that we'd like to answer are not only how large former ice sheets were, but also how fast did the recede and how quickly did they thin?

The point of the mission, which involves researchers from the National Oceanography Centre (NOC), the British Antarctic Survey, Oxford University, and other UK - based institutions, is to determine how much glacial ice is drifting into the ocean, and to gain a better understanding of how water is mixing and behaving across the front of the shelf.

How many locations on the planet can you crawl into bright blue glacial ice caves, fly over an erupting volcano bubbling with lava, AND stay up all night transfixed by magical Northern Lights?

Which leads me to another question — the melting glacial / Greenland / Antarctic ice water is depleted in CO2 (check out the bubbles in your ice cubes)-- how much additional CO2 is being sequestered by this runoff into the oceans, and what happens to CO2 increase when we run out of glaciers?

I'm not sure you want to go there... Remember the glacial maximum in North America was only 18,000 years ago and you could make some simple calculation about the volume of ice involved and how quickly it vanished.

The Vice news program on HBO had an interesting story of how the Glacial land ice is melting in Greenland at a rapid rate.

How, for example, does this incident cast doubt on the findings from satellite data, radiosondes, borehole analysis, glacial melt observations, sea ice melt, sea level rise, proxy reconstructions, permafrost melt and such like, gathered completely independently of the CRU?

The aim of the C - SIDE working group is to reconstruct changes in sea - ice extent in the Southern Ocean for the past 130,000 years, reconstruct how sea - ice cover responded to global cooling as the Earth entered a glacial cycle, and to better understand how sea - ice cover may have influenced nutrient cycling, ocean productivity, air - sea gas exchange, and circulation dynamics.

Gore introduces the concept of abledo and shows how feedback loops could lead to dramatic reductions in ice, especially in the Arctic, and he mentions glacial earthquakes in Greenland, but he doesn't put a timeline on the melting of the ice sheets.

But much stronger albedo effects (a measure of how much sunlight is simply reflected back out into space) might be generated by the high winds of the glacial era, giving 10 °C temperature changes rather than the 1 °C excursion of the Little Ice Age.

In fact, they can't explain how the North American continent covered in a mile thick crust of glacial ice could melt so fast and NO EXPLANATION as to where the Heat came from to melt thousands and thousands of miles of one mile thick ice.

Please liberal climate change scientists, how do you melt tens of thousands of miles of mile thick glacial ice with 144 BTU's per cubic foot of ice.

This ice sheet melted long time ago, but left behind geological evidence of sub glacial processes that now can be put in numerical models, to test hypotheses of how they may work in modern environment.

There are numerous other problems — warm water some how flows preferentially toward glacial grounding lines and stays there to melt the ice.

First let's look at how ice ages — the cold phases of glacial cycles — work on Earth.

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).

The researchers do not yet know whether the draining water is increasing glacial flow, and nor can they be sure how many such depressions in the Greenland ice mask buried meltwater storage tanks.

You have not answered how the ice could accumulate around Northern Europe and America during glacials.
