(PhysOrg.com) -- Diverting sediment-rich water from the Mississippi River below New Orleans could generate new land in the river's delta in the next century. http://www.physorg.com/news175276001.html Space & Earth Tue, 20 Oct 2009 17:10:01 EST news175276001 New ground measurements made by the West Antarctic GPS Network (WAGN) project, composed of researchers from The University of Texas at Austin, The Ohio State University, and The University of Memphis, suggest the rate of ice loss of the West Antarctic ice sheet has been slightly overestimated. http://www.physorg.com/news175172992.html Space & Earth Mon, 19 Oct 2009 12:10:33 EST news175172992 (PhysOrg.com) -- CSIRO scientists have produced the first preliminary predictions of the potential impact of climate change on the Australian seabed. http://www.physorg.com/news174826577.html Space & Earth Thu, 15 Oct 2009 11:56:48 EST news174826577 A new study by researchers at the University of Southampton has found that sea levels have been rising across the south coast of England over the past century, substantially increasing the risk of flooding during storms. http://www.physorg.com/news174302326.html Space & Earth Fri, 09 Oct 2009 10:30:03 EST news174302326 NASA begins a series of flights Oct. 15 to study changes to Antarctica's sea ice, glaciers and ice sheets. The flights are part of Operation Ice Bridge, a six-year campaign that is the largest airborne survey ever made of ice at Earth's polar regions. http://www.physorg.com/news174245200.html Space & Earth Thu, 08 Oct 2009 19:10:02 EST news174245200 The 'Coastland Map' produced by scientists from Durham University and published in the Journal GSA Today, charts the post Ice-Age tilt of the UK and Ireland and current relative sea-level changes. According to the map, the sinking effect in the south could add between 10 and 33 per cent to the projected sea-level rises caused by global warming over the next century. http://www.physorg.com/news174078072.html Space & Earth Tue, 06 Oct 2009 20:50:02 EST news174078072 (PhysOrg.com) -- A new analysis of climate risk, published by researchers at MIT and elsewhere, shows that even moderate carbon-reduction policies now can substantially lower the risk of future climate change. It also shows that quick, global emissions reductions would be required in order to provide a good chance of avoiding a temperature increase of more than 2 degrees Celsius above the pre-industrial level - a widely discussed target. But without prompt action, they found, extreme changes could soon become much more difficult, if not impossible, to control. http://www.physorg.com/news173697789.html Space & Earth Fri, 02 Oct 2009 11:30:01 EST news173697789 (PhysOrg.com) -- A leading climate scientist has presented new research findings on the increasing potential for a 4 degrees Celsius rise in global temperatures if the current high emissions of greenhouse gases continue. http://www.physorg.com/news173368462.html Space & Earth Mon, 28 Sep 2009 15:30:17 EST news173368462 The most comprehensive picture of the rapidly thinning glaciers along the coastline of both the Antarctic and Greenland ice sheets has been created using satellite lasers. The findings are an important step forward in the quest to make more accurate predictions for future sea level rise. http://www.physorg.com/news172931543.html Space & Earth Wed, 23 Sep 2009 13:50:01 EST news172931543 (AP) -- With whale fins splashing in the distance, Ruth Curry hauls up her catch from the blustery deck of an icebreaker. http://www.physorg.com/news172917431.html Space & Earth Wed, 23 Sep 2009 09:50:02 EST news172917431 How to plan for sea level rise, a still-abstract concept for many Californians, drew serious consideration from engineers, designers and urban planners from Holland and the U.S. at a symposium held on Monday. http://www.physorg.com/news172861583.html Space & Earth Tue, 22 Sep 2009 18:07:59 EST news172861583 A new study led by the University of Colorado at Boulder indicates most of the world's low-lying river deltas are sinking from human activity, making them increasingly vulnerable to flooding from rivers and ocean storms and putting tens of millions of people at risk. http://www.physorg.com/news172672245.html Space & Earth Sun, 20 Sep 2009 13:32:12 EST news172672245 (AP) -- Suddenly and without warning, the gigantic river of ice sped up, causing it to spit icebergs ever faster into the ocean off southeastern Greenland. http://www.physorg.com/news171821271.html Space & Earth Thu, 10 Sep 2009 17:39:32 EST news171821271 NOAA, along with the Environmental Protection Agency, the International City/County Management Association and Rhode Island Sea Grant, has released a guide to bring smart growth to coastal and waterfront communities. http://www.physorg.com/news171802223.html Space & Earth Thu, 10 Sep 2009 12:00:01 EST news171802223 Persistent winds and a weakened current in the Mid-Atlantic contributed to higher than normal sea levels along the Eastern Seaboard in June and July, according to a new NOAA technical report. http://www.physorg.com/news171124260.html Space & Earth Wed, 02 Sep 2009 17:40:04 EST news171124260 (AP) -- Folks living along the East Coast were in higher water early this summer thanks to a change in the wind and current flow. http://www.physorg.com/news170943211.html Space & Earth Mon, 31 Aug 2009 13:50:10 EST news170943211 (PhysOrg.com) -- The thinning of a gigantic glacier in Antarctica is accelerating, scientists warned today. http://www.physorg.com/news169471914.html Space & Earth Fri, 14 Aug 2009 13:00:01 EST news169471914 Climate change is shrinking three of the nation's most studied glaciers at an accelerated rate, and government scientists say that finding bolsters global concerns about rising sea levels and the availability of fresh drinking water. http://www.physorg.com/news168849624.html Space & Earth Fri, 07 Aug 2009 08:20:13 EST news168849624 Fossil coral data and temperature records derived from ice-core measurements have been used to place better constraints on future sea level rise, and to test sea level projections. http://www.physorg.com/news167906285.html Space & Earth Mon, 27 Jul 2009 09:40:05 EST news167906285 The oil and gas that fuels our homes and cars started out as living organisms that died, were compressed, and heated under heavy layers of sediments in the Earth's crust. Scientists have debated for years whether some of these hydrocarbons could also have been created deeper in the Earth and formed without organic matter. Now for the first time, scientists have found that ethane and heavier hydrocarbons can be synthesized under the pressure-temperature conditions of the upper mantle -the layer of Earth under the crust and on top of the core. The research was conducted by scientists at the Carnegie Institution's Geophysical Laboratory, with colleagues from Russia and Sweden, and is published in the July 26, advanced on-line issue of Nature Geoscience. http://www.physorg.com/news167835116.html Space & Earth Sun, 26 Jul 2009 14:10:01 EST news167835116 Forty miles off the Jersey Shore, an international team of scientists is grappling with a worrisome phenomenon: The oceans are slowly rising. The researchers are not studying the sea itself. Living for weeks at a time on this drilling platform, they are burrowing down into the past, pulling up cores of prehistoric sediment from nearly half a mile below the ocean floor. http://www.physorg.com/news167211051.html Space & Earth Sun, 19 Jul 2009 08:31:32 EST news167211051 Scientists from the National Oceanography Centre, Southampton, along with colleagues from Tuebingen and Bristol have reconstructed sea-level fluctuations over the last 520,000 years. Comparison of this record with data on global climate and CO2 levels from Antarctic ice cores suggests that even stabilization at today's CO2 levels may commit us to much greater sea-level rise over the next couple of millennia than previously thought. http://www.physorg.com/news164891348.html Space & Earth Mon, 22 Jun 2009 12:09:35 EST news164891348 The Greenland ice sheet is melting faster than expected according to a new study led by a University of Alaska Fairbanks researcher and published in the journal Hydrological Processes. http://www.physorg.com/news164034080.html Space & Earth Fri, 12 Jun 2009 14:01:53 EST news164034080 Melting of the Greenland ice sheet this century may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax, and other cities in the northeastern United States and in Canada, according to new research led by the National Center for Atmospheric Research (NCAR). http://www.physorg.com/news162647903.html Space & Earth Wed, 27 May 2009 12:58:48 EST news162647903 (PhysOrg.com) -- While a total or partial collapse of the West Antarctic Ice Sheet as a result of warming would not raise global sea levels as high as some predict, levels on the U.S. seaboards would rise 25 percent more than the global average and threaten cities like New York, Washington, D.C., and San Francisco, according to a new study. http://www.physorg.com/news161530106.html Space & Earth Thu, 14 May 2009 14:28:52 EST news161530106 (PhysOrg.com) -- We know that average sea levels have risen over the past century, and that global warming is to blame. But what is climate change doing to the saltiness, or salinity, of our oceans? http://www.physorg.com/news160410249.html Space & Earth Fri, 01 May 2009 15:24:41 EST news160410249 A breakthrough study of fluctuations in sea levels the last time Earth was between ice ages, as it is now, shows that oceans rose some three meters in only decades due to collapsing ice sheets. http://www.physorg.com/news159025292.html Space & Earth Wed, 15 Apr 2009 14:42:03 EST news159025292 The threat of global warming can still be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70 percent this century, according to a new analysis. While global temperatures would rise, the most dangerous potential aspects of climate change, including massive losses of Arctic sea ice and permafrost and significant sea level rise, could be partially avoided. http://www.physorg.com/news158929344.html Space & Earth Tue, 14 Apr 2009 12:03:30 EST news158929344 Rising atmospheric carbon dioxide is largely responsible for recent global warming and the rise in sea levels. However, a team of scientists, including two Smithsonian ecologists, have found that this same increase in CO2 may ironically counterbalance some of its negative effects on one of the planet's most valuable ecosystems -wetlands. The team's findings are being published in the Proceedings of the National Academy of Sciences the week of March 23. http://www.physorg.com/news157050125.html Space & Earth Mon, 23 Mar 2009 18:05:38 EST news157050125 (PhysOrg.com) -- Urban areas around the world are places of hidden biodiversity that need to be protected and encouraged through smart urban design, said an authority in green city design. http://www.physorg.com/news157042906.html Biology Mon, 23 Mar 2009 16:03:00 EST news157042906
