Sentences with phrase «huge ice sheets»

At the height of the last Ice Age huge ice sheets covered the northern continents.

The results of such a new ice age would be catastrophic to humans and other life on Earth, including the southward advance of huge ice sheets in the Northern Hemisphere.

The basic reason for this is that there are no proxy data available in the areas which were covered by huge ice sheets back then but which are now bare (particularly North America and Scandinavia), and it is these regions which exhibit the largest anomalies for the LGM.

Imagine huge ice sheets covering North America and northern Europe, glaciers in the Alps and other mountain regions descending much further down the valleys into the low lands, Europe was essentially without forests and tundra covered much of the northern Hemisphere land masses.

H2O is a bigger culprit in the long run, snowing and glaciating the way he does, ever so slowly making himself into huge ice sheets.

The icebergs that find their way into the paths of transatlantic liners come down from the coast of Greenland; for the interior of Greenland is a huge ice sheet fringed by mountains and promontories.

The Arctic took another 3,000 - 4,000 years to warm this much, primarily because of the fact that the Northern Hemisphere had huge ice sheets to buffer warming, and the fact that changes in ocean currents and Earth's orbital configuration accelerated warming in the south.

That's because people have never seen the collapse of a huge ice sheet and therefore don't have good models of the effects, Rignot said.

On the Antarctic Peninsula and in West Antarctica, warming waters are eroding the floating ice shelves that scientists say have impeded the seaward flow of the huge ice sheets of the interior.

Global sea ice cover reached a record low, and mountain glaciers and the huge ice sheets in Greenland and Antarctica are on a trajectory of accelerating mass loss.

West Antarctica has warmed much more than scientists had thought over the last half century, new research suggests, an ominous finding given that the huge ice sheet there may be vulnerable to long - term collapse, with potentially drastic effects on sea levels.

There is no gap between two huge ice sheets, which is very favourable for a quick refreeze.

As Paleoclimatologist named Jack Hall is in Antartica, he discovers that a huge ice sheet has sheared off.

One tricky aspect of measuring the rate of melting of Greenland and Antarctica's huge ice sheets has been accounting for an effect known as «post-glacial rebound» of the Earth's crust.

The scientists used satellite monitoring to determine the contribution of all land - based ice (except for Greenland and Antarctica's huge ice sheets) to rising sea levels and found that the volume of ice melting into the sea each year from ice caps and glaciers was 100 cubic miles (or 417 cubic km).

The melting characteristics of such a huge ice sheet — spanning 656,000 square miles (1.7 million square kilometers)-- is important for various reasons, particularly its potential effect on sea levels.
