Sentences with phrase «moving ice streams»

Jakobshavn Glacier is one of the fastest moving ice streams in the world contributing massive amount of ice to the oceans.

Scientists discover an important clue in predicting future consequences of climate change: the mechanism that moves ice streams

Not exact matches

In comparison, it took the Jakobshavn Isbræ ice stream — a southwest Greenland region with a fast - moving glacier that has been a focal point of scientific examination of ice sheet melt — 150 years to retreat 35 kilometers, said Khan.

For comparison, one of the fastest moving glaciers, the Jakobshavn ice stream in southwest Greenland, has retreated 35 kilometers (21.7 miles) over the last 150 years.

The discovery is significant in relation to the mechanism for rapid movement of the ice streams, which are huge, fast - flowing ice currents within the slow - moving ice sheet that covers most of Antarctica.

Near the coast, most of the ice moves through relatively fast - moving outlets called ice streams, glaciers, and ice shelves.

HERE is a lecture by Dr. Jennifer Francis, Rutgers U. documenting the connection between the loss of Arctic ice due to global warming, slower moving jet streams with larger meandering amplitudes, and increases in extreme weather.

From what scientists have learned, this ice sheet is far from static: It has «streams» of fast - moving ice running toward the sea at a rate of several kilometers a year.

The thick and slow - moving interior ice reservoir is generally fixed to the underlying bedrock while the ice streams glide over lubricated beds at velocities of up to several hundred metres per year.

In an article on September 12, I reported on a 2012 paper by Jennifer Francis of Rutgers University and Stephen Vavrus of the University of Wisconsin, which showed that the loss of Arctic summer sea ice cover is adding enough heat to the ocean and atmosphere that it is helping to redirect the jet stream — the fast - moving high - altitude river of air that steers storm systems across the northern hemisphere.

The snow that falls around the Arctic does cause the jet stream to move more south and that does cause snow to fall more south, on the heads of glaciers and ice packs around the northern hemisphere.
