New Tide Gauge Measures Sea Level Change Using GPS Signals

2014-05-22 01:18:00| Climate Ark Climate Change & Global Warming Newsfeed

RedOrbit: A new way of measuring sea level using satellite navigation system signals, for instance GPS, has been implemented by scientists at Chalmers University of Technology in Sweden. Sea level and its variation can easily be monitored using existing coastal GPS stations, the scientists have shown. ?Measuring sea level is an increasingly important part of climate research, and a rising mean sea level is one of the most tangible consequences of climate change. Researchers at Chalmers University of Technology...

Greenland Could Become Greater Contributor To Sea Level Rise Than Previously Expected

2014-05-19 13:18:00| Climate Ark Climate Change & Global Warming Newsfeed

RedOrbit: Greenland`s icy reaches are far more vulnerable to warm ocean waters from climate change than had been thought, according to new research by UC Irvine and NASA glaciologists. The work, published May 18 in Nature Geoscience, shows previously uncharted deep valleys stretching for dozens of miles under the Greenland Ice Sheet. The bedrock canyons sit well below sea level, meaning that as subtropical Atlantic waters hit the fronts of hundreds of glaciers, those edges will erode much further than had...

Antarctica Glacier Collapsing, Adding to Sea Level Rise

2014-05-12 20:31:00| Climate Ark Climate Change & Global Warming Newsfeed

National Geographic: A massive glacier system in West Antarctica has started collapsing because of global warming and will contribute to significant worldwide sea-level rise, two teams of scientists warn in a pair of major studies released Monday. Scientists had previously thought the two-mile-thick (3.2 kilometers) glacier system would remain stable for thousands of years, but new research suggests a faster time frame for melting. A rapidly melting section of the West Antarctic Ice Sheet appears to be in irreversible...

Glaciers draining Antarctic basin destabilized, big sea level rise all but certain

2014-05-12 14:16:00| Climate Ark Climate Change & Global Warming Newsfeed

Ars Technica: Today, researchers at UC Irvine and the Jet Propulsion Laboratory have announced results indicating that glaciers across a large area of West Antarctica have been destabilized and that there is little that will stop their continuing retreat. These glaciers are all that stand between the ocean and a massive basin of ice that sits below sea level. Should the sea invade this basin, we'd be committed to several meters of sea level rise. Even in the short term, the new findings should increase our...

Not Just Sea Level Rise: Northeast Faces Flooding From The Skies

2014-05-08 14:56:00| Climate Ark Climate Change & Global Warming Newsfeed

ThinkProgress: The nation`s capital and financial center, not to mention other major metropolitan areas in the Northeast, are going to get soggy. And not just because of dramatic sea level rise and storm surge. The third National Climate Assessment, released Tuesday, stresses that the onslaught of water will come from the skies as well as the oceans. In the aftermath of Superstorm Sandy, which slammed into the East Coast in October 2012, causing up to $80 billion in damage, most people in the Northeast quickly...
