Warming Oceans May Be Driving Sea-Ice Expansion In Antarctica
2013-04-01 07:07:28

Lawrence LeBlond for redOrbit.com - Your Universe Online A growing number of studies have pegged global warming and climate change as a cause of sea-ice decline in recent decades. However, a newly published study in the journal Nature Geoscience is showing a vastly different scenario. According to researchers at the Royal Netherlands Meteorological Institute (KNMI), ocean warming may actually be driving sea-ice expansion in the Antarctic. While sea ice at the North Pole has shrunk...

Greenland's Peripheral Glaciers Also Contribute Significantly To Sea-Level Rise
2013-03-18 13:39:33

Alan McStravick for redOrbit.com - Your Universe Online The oft-cliché idea behind the naming of Iceland and Greenland claims their names were derived in an attempt to fool would be sailing marauders, attracting them to the desolate but more hospitably named Greenland, leaving the citizens of Iceland to live upon their slightly more lush island without threat of invasion. In fact, Erik the Red, it is believed, gave the moniker to attract settlers to the ice covered island...

Global Sea-Level Rise Could Occur Unevenly Across Globe
2013-02-19 15:43:16

Peter Suciu for redOrbit.com — Your Universe Online The fact sea levels could rise if the polar ice caps melt has been long established, but according to new research some regions could see greater increases than others. According to research published in the journal Geophysical Research Letters, sophisticated computer modeling of sea-level rise over the coming century suggests parts of the Pacific could see the highest rates of rise while some polar regions will actually...

Sea Level Predictions Aided By New Antarctic Geological Timeline
2013-01-16 18:35:25

Alan McStravick for redOrbit.com — Your Universe Online The uncertainty of future sea level rise is getting a little clearer thanks to research being conducted by a team comprised of scientists from the British Antarctic Survey (BAS), the Alfred Wegner Institute for Polar and Marine Research (AWI) and the University of Tromsø. Their study, entitled ℠Grounding-line retreat of the West Antarctic Ice Sheet from inner Pine Island Bay´, is being published in this...

Warm Seas Melting Antarctic Ice Sheet Faster Than Expected
2012-12-07 13:15:29

April Flowers for redOrbit.com - Your Universe Online The West Antarctica ice sheet is melting faster than expected. An international group of oceanographers led by the University of Gothenburg has published new observations in the journal Nature Geoscience that may improve our ability to predict future changes in ice sheet mass. The water levels of the oceans would be affected globally by a reduction of the ice sheets in Antarctica and Greenland, making it problematic that...

Ice Sheet Loss At Both Poles Is Clearly Increasing
2012-11-30 08:10:18

April Flowers for redOrbit.com - Your Universe Online In a new study that ends 20 years of uncertainty, an international team of satellite experts have produced the most accurate assessment of ice losses from Antarctica and Greenland to date. Published in the journal Science, the landmark study shows that the melting of the Antarctic and Greenland ice sheets has contributed 11.1 millimeters to global sea levels since 1992, amounting to one fifth of all sea level rise over the survey...

An enhanced approach to capturing changes on the Earth's surface via satellite could provide a more accurate account of how ice sheets, river basins and other geographic areas are changing as a result of natural and human factors. In a first application, the technique revealed sharper-than-ever details about Greenland's massive ice sheet, including that the rate at which it is melting might be accelerating more slowly than predicted. Princeton University researchers developed a...

Anthropogenic Climate Change Leads To Melting Glaciers And Rising Sea Level
2012-11-14 15:22:41

University of Innsbruck Between 1902 and 2009, melting glaciers contributed 11 cm to sea level rise. They were therefore the most important cause of sea level rise. This is the result of a new assessment by scientists of the University of Innsbruck. They numerically modeled the changes of each of the world´s 300 000 glaciers. Until 2100, glaciers could lead to an additional 22 cm of sea level rise. Since 1900 the global sea level has risen by approximately 20 cm. Melting glaciers...

Antarctic Ice Facing Changes By Fast-Flowing Glaciers
2012-09-19 14:14:23

Lee Rannals for redOrbit.com — Your Universe Online A new study found that fast-flowing and narrow glaciers could trigger massive changes in the Antarctic ice sheet, inevitably adding sea-level rise and ice-sheet decay. The team tested high-resolution model simulations against reconstructions of the Antarctic ice sheet from 20,000 years ago. Writing in the journal Proceedings of the National Academy of Sciences (PNAS), they said they used a new model during their study, capable...


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
