China pours cash into melting Arctic in bid to win influence

2013-03-18 21:28:00| Climate Ark Climate Change & Global Warming Newsfeed

Guardian: At face value, it is not one of the world's most important relationships. When Norway and China fell out two years ago over a Nobel prize awarded to a Chinese dissident, the spat had little wider resonance. But diplomatic relations are thawing as quickly as Arctic ice and the upshot could be significant for the frigid northern wastes of the planet, which are thought to sit on formidable quantities of mineral reserves. China has been cosying up to Arctic countries as part of its effort to...

Arctic melting stacked weather deck in favor of Superstorm Sandy

2013-03-16 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed

ClimateWire: A number of unusual atmospheric phenomena combined to form the massive "Frankenstorm" that was Superstorm Sandy. While many have said global warming fueled the storm's strength, it is unclear exactly how it played a role. But scientists are starting to see evidence that warm weather in the Arctic led to conditions that made the hurricane so incredibly powerful. An article in the March issue of Oceanography, authored by scientists from Cornell and Rutgers universities, points to 2012's unprecedented...

The melting of Canada's glaciers is irreversible

2013-03-08 20:18:00| Climate Ark Climate Change & Global Warming Newsfeed

New Scientist: See Canada's glaciers while you still can. Their melting is irreversible, according to projections based on real-world data and validated by satellite images. By the end of the century, a fifth of the Canadian ice sheet - the world's third largest - could be gone for good, raising average global sea levels by 3.5 centimetres. If the whole ice sheet melts, it would raise the global sea level by about 20 centimetres, a fraction of the 70 and 7 metre rises expected respectively if Antarctica and...

Melting Arctic Ice Will Make Way for More Ships and More Species Invasions

2013-03-06 17:29:00| Climate Ark Climate Change & Global Warming Newsfeed

Scientific American: The rare ships that have ventured through the harsh, icebound Arctic Ocean require reinforced hulls and ice-breaking bows that allow them to plow through dense ice as much as two meters deep, and face hazardous conditions in remote locations for long periods of time. Arctic sea ice now is melting so rapidly each summer due to global warming, however, that ships without ice-breaking hulls will be able to cross previously inaccessible parts of the Arctic Ocean by 2050. And light-weight ships equipped...

Sunderland student plots the Arctic's melting ice

2013-02-27 17:17:00| Climate Ark Climate Change & Global Warming Newsfeed

Guardian: Sir Ranulph Fiennes' prudent withdrawal from Antarctica comes in the same week as the successful return from the Arctic of a student at Sunderland University, which has an interesting niche in Polar research. Matthew Ayre, who is 25 and from Tynemouth, has been working on ice melt, both contemporary and historical, on board the United States icebreaker Healy during a five week voyage in the Arctic Ocean. He got the billet because Sunderland has made a speciality of the study of captains' logs,...
