The Big Melt accelerates

New York Times: Centuries from now, a large swath of the West Antarctic ice sheet is likely to be gone, its hundreds of trillions of tons of ice melted, causing a four-foot rise in already swollen seas. Scientists reported last week that the scenario may be inevitable, with new research concluding that some giant glaciers had passed the point of no return, possibly setting off a chain reaction that could doom the rest of the ice sheet. For many, the research signaled that changes in the earths climate have already...

Greenland Glaciers More Susceptible to Melt Than Thought
2014-05-18 19:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Greenland's glaciers are more vulnerable to melting by warm ocean waters than previously thought, a new study of the topography of the bedrock under the ice finds. This clearer picture of the underpinnings of the miles-thick ice sheet, along with other recent studies that suggest parts of Earth's polar regions are not as stable as once thought, could mean that current projections of future sea level rise are too low. On April 8, 2011, NASA's Operation IceBridge flew a mission to coastal areas...

Greenland glacial melt is growing factor rising sea levels

Al Jazeera: Greenlands glaciers are far more vulnerable to climate change-induced warming oceans than previously thought, a report released Sunday by UC- Irvine and NASA glaciologists said. The study, published in the journal Nature Geoscience, reveals previously uncharted deep valleys stretching for dozens of miles under the Greenland Ice Sheet -- showing that there are no natural barriers to stop the melting. The findings echo a report released last week showing that glacial melting in West Antarctica...

Unprecedented BC glacier melt seeps into US climate change concerns
2014-05-18 15:24:00| Climate Ark Climate Change & Global Warming Newsfeed
CBC: The mountains of British Columbia cradle glaciers that have scored the landscape over millennia, shaping the rugged West Coast since long before it was the West Coast. But they're in rapid retreat, and an American state-of-the-union report on climate change has singled out the rapid melt in British Columbia and Alaska as a major climate change issue. "Most glaciers in Alaska and British Columbia are shrinking substantially," said the U.S. National Climate Assessment, released last week to much...

Future Ice Melt Patterns In Antarctica
2014-05-16 21:50:00| Climate Ark Climate Change & Global Warming Newsfeed
Planetsave: One of the main impacts of climate change is sea level rise, brought about through melting of the worlds ice sheets and glaciers, as well as through thermal expansion of the oceans. The vast majority of worlds fresh water is locked up in the massive ice sheets covering Antarctica and Greenland. Of the two, Antarctica is by far the larger, holding about twelve times as much ice as Greenland. While the antarctic continent has not yet contributed a great deal to rising sea levels, it has the potential...
