Warmer Arctic with Less Ice Increases Storm Surge
2013-03-06 03:08:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Rising temperatures are shrinking Arctic sea ice, and in Canada's Northwest Territories, that means more and stronger storm surges, according to a new study. An analysis of lakebed sediments from one section of the outer Mackenzie Delta shows surges have become more intense and frequent over the past 150 years as the region has warmed and ice has retreated. The sharpest increase in surge activity came after 1980, in concert with the steepest declines in Arctic sea ice cover, concludes the research,...

More storms like Sandy? Arctic ice loss amplified Superstorm Sandy violence

ScienceDaily: If you believe that last October's Superstorm Sandy was a freak of nature -- the confluence of unusual meteorological, atmospheric and celestial events -- think again. Cornell and Rutgers researchers report in the March issue of Oceanography that the severe loss of summertime Arctic sea ice -- attributed to greenhouse warming -- appears to enhance Northern Hemisphere jet stream meandering, intensify Arctic air mass invasions toward middle latitudes, and increase the frequency of atmospheric blocking...
Climate change will open up surprising new Arctic shipping routes
2013-03-05 21:38:00| Climate Ark Climate Change & Global Warming Newsfeed
Washington Post: Right now, the Arctic Ocean is still too icy and treacherous for open-water ships to traverse with any regularity. The Northwest Passage is only navigable during the summer months once every seven years or so. Too unreliable for commercial shipping. This will all get a lot easier. But that will soon change. As the planet keeps warming, the Arctic`s summer sea ice is vanishing at a stunning pace. That rapid melt is expected to have all sorts of sweeping impacts, from speeding up climate change...

As Arctic ice melts, full steam ahead for shipping
2013-03-05 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
USA Today: There will certainly be more negative than positive effects from climate change. But shipping routes across the Arctic Ocean -- which have been ice-covered and impassable since humans invented ships millenniums ago -- could be open for the first time by midcentury because of climate change, a study suggests. This includes shipping directly across the North Pole and through the famed Northwest Passage, a sea route from Newfoundland toward the Bering Strait, neither of which has ever been done....
Study: Global warming could help Arctic shipping
2013-03-05 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
USA Today: A study suggests that global warming is opening up a first-time chance to cruise through the Northwest Passage, which could translate into big savings in time and money for shippers. Who said global warming is all bad? There will certainly be many more negative effects than positive ones from climate change. But shipping routes across the Arctic Ocean which have been ice-covered and impassable since humans invented ships millenniums ago could be open to ships for the first time by midcentury,...
