More storms like Sandy? Arctic ice loss amplified Superstorm Sandy violence
2013-03-05 21:45:00| Climate Ark Climate Change & Global Warming Newsfeed
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...
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....
Researchers find that life on Earth could have originated from space ice dust
2013-03-02 15:31:56| Extremetech
This week, researchers announced that they used a powerful telescope called the Green Bank Telescope to identify two of the most sought-after life-forming molecules -- and they've found them floating on ice grains near the center of the galaxy.
Ice Core Data Help Solve a Global Warming Mystery

Scientific American: Scientists can study Earth's climate as far back as 800,000 years by drilling core samples from deep underneath the ice sheets of Greenland and Antarctica. Detailed information on air temperature and CO2 levels is trapped in these specimens. Current polar records show an intimate connection between atmospheric carbon dioxide and temperature in the natural world. In essence, when one goes up, the other one follows. There is, however, still a degree of uncertainty about which came first--a spike...
Ice Bubbles May Solve Carbon-Temperature Paradox

Climate Central: Scientists may have resolved a long-standing puzzle in climate science by showing that ancient increases in atmospheric carbon dioxide came at the same time as rising temperatures, rather than hundreds of years afterward. In a new analysis of bubbles trapped in Antarctic ice, published Thursday in Science, lead author Frederic Parrenin of the Laboratory of Glaciology and Geophysics of the Environment, in Grenoble, France, and his colleagues write that at the end of the last ice age, about 20,000...
