Sentences with phrase «summer sea ice cover»

Reduced summer sea ice cover allows for greater warming of the upper ocean but atmospheric warming is modest.

Summer sea ice continues to decline — the 2009 - 2010 summer sea ice cover extent was the third lowest since satellite monitoring began in 1979, and sea ice thickness continues to thin.

The new studies, which are both published in Nature Climate Change, focus in on how efforts to curb climate change could affect summer sea ice cover in the Arctic.

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 projected reduction is accelerated in the Arctic, where some models project summer sea ice cover to disappear entirely in the high - emission A2 scenario in the latter part of the 21st century.

This novel study calculated that for every tonne of CO2 emitted into the atmosphere, summer sea ice cover in the Arctic shrinks by three square metres.

Key Points: Region Continues to Warm at Unprecedented Rate • Greenland is experiencing record - setting high temperatures, ice melt and glacier area loss; • Summer sea ice continues to decline — the 2009 - 2010 summer sea ice cover extent was the third lowest since satellite monitoring began in 1979, and sea ice thickness continues to thin.

Record temperatures across Canadian Arctic and Greenland, a reduced summer sea ice cover, record snow cover decreases and links to some Northern Hemisphere weather support this conclusion.»

We'll have ice, but we will lose the summer sea ice cover.

«An ongoing US Department of Energy - backed research project led by a US Navy scientist predicts that the Arctic could lose its summer sea ice cover as early as 2016 — 84 years ahead of conventional model projections.»

Ever since satellites allowed a detailed view of the Arctic and its ice, a pronounced decrease in summer sea ice cover has been observed (with this year setting a new record low).

Since the satellite record began in 1979, summer sea ice cover has fallen by around 13 % per decade, with rising temperatures playing a large role in the decline.

In September, National Snow and Ice Data Center's director Mark Serreze said, «The volume of ice left in the Arctic likely reached the lowest ever level this month» and «I stand by my previous statements that the Arctic summer sea ice cover is in a death spiral.
