Sentences with phrase «sea ice coverage which»

Not exact matches

Last Friday afternoon, on a conference call hosted by the National Research Council to present a recent report on the Arctic region, Stephanie Pfirman, an environmental science professor at Barnard College, said Arctic ice coverage is shrinking and that thicker sea ice blocks, which anchor much of the landscape, are rapidly melting.

During the so - called Holocene Climate Optimum, from approximately 8000 to 5000 years ago, when the temperatures were somewhat warmer than today, there was significantly less sea ice in the Arctic Ocean, probably less than 50 % of the summer 2007 coverage, which is absolutely lowest on record.

It is not that the polar regions are amplifying the warming «going on» at lower latitudes, it is that any warming going on AT THE POLES is amplified through inherent positive feedback processes AT THE POLES, and specifically this is primarily the ice - albedo positive feedback process whereby more open water leads to more warming leads to more open water, etc. *** «Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...»

«Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...»

By contrast atmospheric temperature amplification is not evident in the Antarctic which is insulated by relatively stable circumpolar winds, persistent sea - ice coverage and the loss of tropospheric ozone.

Some have claimed it was complete global coverage of sea, though it seems me more would claim there remained corridor of tropical ocean which remain ice free.

Slate's Phil Plait was responsibly reserved in his coverage, emphasizing that although one of the press releases used the word «collapse,» the melting of this particular glacier — which by itself contains enough ice to raise global seas by three feet — is a process that will take centuries, if not longer, to play out.

Sea ice coverage is particularly low in the Barents and Kara seas, which sit north of Scandinavia and Russia and have been in the path of those incoming storms.

Albedo should increase in response to very low solar conditions which should result in an increase in major volcanic activity, increase in global cloud coverage and sea ice / snow coverage.
