According to an international report, climate change in the Arctic could raise world sea levels to 5 feet by 2100. A rise like this would threaten the coasts from Bangladesh to Florida, low-lying Pacific islands and cities from London to Shanghai.  It would also raise costs of building tsunami barriers in Japan. "The past six years (until 2010) have been the warmest period ever recorded in the Arctic," according to the Oslo-based Arctic Monitoring and Assessment Programme (AMAP). "In...

According to a new study, melting glaciers and ice caps on Canadian Arctic islands play a much greater role in sea level rise than scientists previously thought. There are bout 30,000 islands within the 550,000-square-mile Canadian Arctic Archipelago.  The study found that between 2004 and 2009, the region lost the equivalent of three-quarters of the water in Lake Erie. Alex Gardner, a research fellow in the Department of Atmospheric, Oceanic and Space Sciences at the University of...

The Antarctic Peninsula has warmed rapidly for the last half-century or more, and recent studies have shown that an adjacent area, continental West Antarctica, has steadily warmed for at least 30 years, but scientists haven't been sure why. New University of Washington research shows that rising sea surface temperatures in the area of the Pacific Ocean along the equator and near the International Date Line drive atmospheric circulation that has caused some of the largest shifts in Antarctic...

New forecasts on rising sea levels suggest that New York will be a big loser, while some regions, including those closer to polar regions, will win big, reports BBC News.. A 2007 report from the Intergovernmental Panel on Climate Change forecast sea levels to rise by as much as 1 foot by 2100. But that forecast was a global average. A Dutch team has now made an attempt to model all the factors leading to regional variations. And whatever the global figure turns out to be, there will be...

Ice sheets have been losing mass at an accelerated rate over the past two decades, and these changes could soon become the dominant contributor to rising global sea levels, a NASA-funded study has discovered. The results of the nearly 20-year satellite research project--the longest study ever to track changes in polar ice sheet mass--showed that ice sheets in Greenland and the Antarctic lost an average of 475 gigatons of combined mass annually. Each gigaton is roughly equal to 2.2 trillion...

An international team of scientists working in the most remote parts of Antarctica have discovered that masses of ice form underneath the ice sheet instead of on top, according to a study published Thursday in the journal Science.Liquid water locked deep under Antarctica's coat of ice regularly thaws, and then refreezes to the bottom, creating as much as half the thickness of the ice in some places, the researchers said. "We usually think of ice sheets like cakes -- one layer at a time added...

Research project completes drilling for the year, reaching two miles below West Antarctic Ice SheetOn Friday, Jan. 28 in Antarctica, a research team investigating the last 100,000 years of Earth's climate history reached an important milestone completing the main ice core to a depth of 3,331 meters (10,928 feet) at West Antarctic Ice Sheet Divide (WAIS). The project will be completed over the next two years with some additional coring and borehole logging to obtain additional information and...

High-Resolution Video, Photos Available Upon Request New York (Vocus/PRWEB) January 20, 2011 New research shows that 2010 set new records for the melting of the Greenland Ice Sheet, expected to be a major contributor to projected sea level rises in coming decades. "This past melt season was exceptional, with melting in some areas stretching up to 50 days longer than average," said Dr. Marco Tedesco, Director of the Cryosphere Processes Laboratory at the City College of New York (CCNY...

Scientists have previously shown that West Antarctica is losing ice, but how that ice is lost remained unclear. Now, using data from Earth observing satellites and airborne science missions, scientists are closing in on ice loss culprits above and below the ice. The findings, presented Dec. 15 at the fall meeting of the American Geophysical Union (AGU) in San Francisco, Calif., are expected to improve predictions of sea level rise.

Southampton researchers have estimated that  sea-level rose by an average of about 1 meter per century at the end of the last Ice Age, interrupted by rapid "Ëœjumps' during which it rose by up to 2.5 meters per century. The findings, published in Global and Planetary Change, will help unravel the responses of ocean circulation and climate to large inputs of ice-sheet meltwater to the world ocean. Global sea level rose by a total of more than 120 meters as the vast ice sheets of...

omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
