Sea Level Rise (Page 2)
Experts fear 1m sea level rise by 2100New Zealand Herald | 08 Jan 2013
Glaciologists fear they may have seriously underestimated the potential for melting ice sheets to contribute to catastrophic sea-level rises which could see increases of a metre or more by 2100.
Antarctica warming at triple speedNew Zealand Herald | 27 Dec 2012
Temperatures in the western part of Antarctica are rising almost twice as fast as previously believed, adding to fears that continued thaws are causing sea levels to rise, according to comprehensive research published this week.
Antarctic warming concern risesBBC | 23 Dec 2012
A new analysis of temperature records indicates that the Western Antarctic Ice Sheet is warming far more rapidly than previously thought.
More ice loss through snowfall on AntarcticaEurekAlert | 12 Dec 2012
(Potsdam Institute for Climate Impact Research (PIK)) Stronger snowfall increases future ice discharge from Antarctica. Global warming leads to more precipitation as warmer air holds more moisture -- hence earlier research suggested the Antarctic ice sheet might grow under climate change. Now a study published in Nature shows that a lot of the ice gain due to increased snowfall is countered by an acceleration of ice-flow to the ocean.
Experts available to discuss new paper detailing global sea level rise scenarioEurekAlert | 05 Dec 2012
On Dec. 6, NOAA will release a technical report that estimates global mean sea level rise over the next century based on a comprehensive synthesis of existing scientific literature. The report finds that there is very high confidence (greater than 90 percent chance) that global mean sea level will rise at least 8 inches (0.2 meters) and no more than 6.6 feet (2 meters) by 2100, depending upon uncertainties associated with ice sheet loss and ocean warming.
Evaluating the risk to Ramsar Sites from climate change induced sea level riseRamsar Convention | 04 Dec 2012
This Briefing Note and the accompanying web map service and data sets, developed by the Center for International Earth Science Information Network (CIESIN) of Columbia University, provide a preliminary assessment of the risk to coastal wetlands designated as Wetlands of International Importance (Ramsar Sites) under the Ramsar Convention on Wetlands from rising sea levels due to climate change.
Sea-level rise finally quantifiedBBC | 29 Nov 2012
An international effort of more than 20 polar research groups finally settles the question of how much polar ice melting has added to global sea levels.
Greenland and Antarctica 'have lost 4tn tonnes of ice' in 20 yearsGuardian Unlimited | 29 Nov 2012
More than 4tn tonnes of ice from Greenland and Antarctica has melted in the past 20 years and flowed into the oceans, pushing up sea levels, according to a study that provides the best measure to date of the effect climate change is having on the earth's biggest ice sheets.
Researcher studies 'middle ground' of sea-level changeEurekAlert | 27 Nov 2012
The effects of storm surge and sea-level rise have become topics of everyday conversation in the days and weeks following Hurricane Sandy's catastrophic landfall along the mid-Atlantic coast. Research at the Virginia Institute of Marine Science is throwing light on another, less-familiar component...
Projected sea-level rise may be underestimatedEurekAlert | 27 Nov 2012
The rate of sea-level rise in the past decades is greater than projected by the latest assessments of the IPCC, while global temperature increases in good agreement with its best estimates. This is shown by a study now published in the journal Environmental Research Letters. Stefan Rahmstorf from the Potsdam Institute for Climate Impact Research and his colleagues compare climate projections to actual observations from 1990 up to 2011.
Sea-levels rising faster than IPCC projectionsEurekAlert | 27 Nov 2012
(Institute of Physics) Sea-levels are rising 60 per cent faster than the Intergovernmental Panel on Climate Change's central projections, new research suggests.
Warming temperatures will change Greenland's faceEurekAlert | 13 Nov 2012
(City College of New York) Global climate models abound. What is harder to pin down, is how a warmer global temperature might affect any specific region on Earth. Dr. Marco Tedesco, associate professor of earth and atmospheric sciences, and a colleague have made the global local. Using a combination of climate models, they predict how different greenhouse gas scenarios would change the face of Greenland and impact sea level rise.
Face-to-face with sustainable development challengesUN News Centre | 08 Nov 2012
Small Island Developing States (SIDS) around the world face unique challenges in the context of sustainable development, including vulnerabilities to climate change such as a rise in sea-levels. If we dont address climate change, islands may not exist, said the Foreign Minister of the Republic of Seychelles, Mr. Jean-Paul Adam, in an exclusive interview with DESAs Division for Sustainable Development.
Why seas are rising ahead of predictionsEurekAlert | 02 Nov 2012
(Geological Society of America) Sea levels are rising faster than expected from global warming, and University of Colorado geologist Bill Hay has a good idea why. The last official IPCC report in 2007 projected a global sea level rise between 0.2 and 0.5 meters by the year 2100. But current sea-level rise measurements meet or exceed the high end of that range and suggest a rise of one meter or more by the end of the century.
