Rising Sea Waters Threaten Hawaiian Shorelines
2013-08-31 08:19:16

April Flowers for redOrbit.com - Your Universe Online In Hawaii, sea-level rise (SLR) has been isolated as a principal cause of coastal erosion. After examining other influences on shoreline change including waves, sediment supply and littoral processes, and anthropogenic changes, the best explanation for the difference in island-wide shoreline trends, such as beach erosion or accretion, is the differing rates of relative sea-level rise on the islands of Oahu and Maui. A new study,...

Grand Canyon Found Lurking Beneath Greenland's Ice Sheet
2013-08-30 04:06:35

[ Watch the Video: Greenland’s Mega Canyon ] redOrbit Staff & Wire Reports - Your Universe Online One of the largest canyons in the world has been discovered beneath the Greenland ice sheet, according to new research appearing in the latest edition of the journal Science. Lead author Jonathan Bamber, a professor at the University of Bristol’s School of Geographical Sciences, and colleagues report the canyon is at least 460 miles (750km) long, up to 2,600 feet (800m) deep in...

Smallest Continent Had Biggest Role In Sea Level Drop
2013-08-20 08:53:03

NASA A unique and complex set of circumstances came together over Australia from 2010 to 2011 to cause Earth’s smallest continent to be the biggest contributor to the observed drop in global sea level rise during that time, finds a new study co-authored and co-funded by NASA. In 2011, scientists at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., and the University of Colorado at Boulder reported that between early 2010 and summer 2011, global sea level fell sharply, by about a...

When enough raindrops fall over land instead of the ocean, they begin to add up. New research led by NCAR shows that three atmospheric patterns drove so much precipitation over Australia in 2010 and 2011 that the world’s ocean levels dropped measurably. Boulder, CO (PRWEB) August 19, 2013 When enough raindrops fall over land instead of the ocean, they begin to add up. New research led by the National Center for Atmospheric Research (NCAR) shows that when three atmospheric patterns came...

Climate change combined with rapid population increases, economic growth and land subsidence could lead to a more than nine-fold increase in the global risk of floods in large port cities between now and 2050. 'Future Flood Losses in Major Coastal Cities', published in Nature Climate Change, is part of an ongoing project by the Organisation for Economic Co-operation and Development (OECD) to explore the policy implications of flood risks due to climate change and economic development. This...

Glacial Melt Minimal Effect On Sea Level
2013-08-13 09:47:09

Brett Smith for redOrbit.com - Your Universe Online Occasionally, melt water on top of a glacier will trickle down to the bedrock below and act as a lubricant for the glacier’s movements. Once thought to be a major contributor to sea-level rise, melt water was found to have only a minor effect on sea level in a new study from a team of European and American scientists. Using computer modeling based on observations of Greenland’s ice sheet, the research team concluded glacier...

Greenland Ice Sheet Is Melting From Below
2013-08-12 04:20:03

redOrbit Staff & Wire Reports - Your Universe Online High heat flow from the mantle into the lithosphere is causing the Greenland ice sheet to melt from below, according to new research published in Sunday’s online edition of the journal Nature Geoscience. This phenomenon, the researchers explain, is very variable spatially and originates in an exceptionally thin lithosphere (the Earth’s crust and upper mantle). As a result, they report there is an increase in the heat flow from...

Estuaries Feeling The Effects Of Climate Change
2013-08-08 04:36:02

April Flowers for redOrbit.com - Your Universe Online A new report from the National Oceanic and Atmospheric Administration's (NOAA) National Ocean Service reveals the nation's 28 National Estuarine Research Reserves (NERR) are experiencing the negative effects of human and climate-related stressors. The NERR System serves as a network of "living laboratories" around the country. Each represents a unique biogeographically diverse coastal ecosystem. The national study, Climate...

Coastal American Cities Threatened By Sea-Level Rise
2013-07-31 08:55:40

Michael Harper for redOrbit.com - Your Universe Online Boston, Miami, New York and more than 1,700 other coastal American cities are facing a greater risk from rising sea levels than had previously been estimated. A new study published in the Proceedings of the National Academy of Sciences (PNAS) claims at least 316 American cities will one day be overtaken by the sea if pollution continues to grow as it has been. More than 1,400 other cities will be "locked-in" by rising sea...

Study Explains Surprising Acceleration Of Greenland's Inland Ice
2013-07-24 14:49:30

NASA [ Watch The Video Greenland Ice Flow ] Surface meltwater draining through cracks in an ice sheet can warm the sheet from the inside, softening the ice and letting it flow faster, a new NASA-funded study finds. During the last decade, researchers have captured compelling evidence of accelerating ice flow at terminal regions, or "snouts," of Greenland glaciers as they flow into the ocean along the western coast. Now, the new research shows that the interior regions are also...

Current Sea Level Rise
2013-04-01 10:39:21

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...
