West Antarctic Ice Sheet Warming Faster
2012-12-24 05:32:08

redOrbit Staff & Wire Reports - Your Universe Online A portion of the Antarctic ice sheet is warming nearly twice as quickly as experts had previously believed, which could increase the region's future contribution to rising sea levels, a team of researchers from the Ohio State University (OSU) has discovered. According to BBC News Environmental Correspondent Matt McGrath, the study authors analyzed temperature records from Byrd Station, a scientific outpost in the center of the...

Ocean Currents Helps Predict Arctic Sea Ice
2012-11-21 15:07:41

Lee Rannals for redOrbit.com - Your Universe Online Researchers at MIT have developed a new method for optimally combining models and observations of the Arctic Ocean to accurately simulate the seasonal extent of the ice change and the ocean circulation beneath. The Arctic Ocean freezes each winter to form sheets of sea ice that spread over millions of square miles. This ice then acts as a massive sun visor for the Earth and helps to reflect solar radiation and shield the planet from...

Rising Temperatures Could Lead To Sea Levels Rising Three Feet Or More
2012-11-15 13:56:59

April Flowers for redOrbit.com - Your Universe Online A rapid response between global temperatures and ice volume/sea-level that could lead to sea-levels rising by over 3 feet have been revealed by a new study from the University of Southampton. Global ice-volume variability has been one of the main feedback mechanisms in climate change during the last few million years. This is because of the strong reflective properties of large ice sheets. Scientists reconstruct ice volume...

NASA Studies Antarctic Sea Ice
2012-11-14 19:43:13

Alan McStravick for redOrbit.com — Your Universe Online A new study by NASA and the British Antarctic Survey tries to explain the increase of ice cover in the Antarctic that is seemingly contrary to the effects of climate change that have been witnessed over the previous two decades. In their report, they purport they have the first direct evidence that this increase in sea ice cover is due to changing winds that have had an impact on the changes to Antarctic sea ice drift. The...

Greenland Could Be Affected By Warming Temperatures
2012-11-14 09:01:27

April Flowers for redOrbit.com - Your Universe Online There are almost as many global climate models as there are climate scientists. Even with all of these models, however, it's very difficult to pin down how warming temperatures globally will affect any specific region. A research team from The City College of New York and the University of Liege, Belgium, and supported by the National Science Foundation (NSF), have made the "global local" using the output of three global models and...

Understanding Antarctic Ice Loss
2012-10-22 19:44:40

Alan McStravick for redOrbit.com — Your Universe Online Amazing GRACE. Scientists and researchers have some interesting news out of Antarctica. The rate of global sea level change has been fairly well-established. The understanding for exactly why this is occurring got a new wrinkle this past week. Utilizing the Gravity Recovery and Climate Experiment (GRACE) satellite data, a team was able to more accurately calculate the ice sheet mass loss by mapping and removing the mass changes...

Polar Ice Sheet Melt Influenced By Underwater Landscape
2012-10-17 12:25:09

Brett Smith for redOrbit.com - Your Universe Online As average global temperatures rise, climatologists are scrambling to see how this development might affect polar ice sheet melt, which could potentially result in a dangerous rise in sea levels. In studying the polar ice sheets around Antarctica, a group of British researchers has found that the shape of water channels beneath the ice can have a strong effect on ice behavior, temporarily hiding indications of its retreat. A report...

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...

Baffin Island Provides Clues To Glacier Melt
2012-09-14 09:16:08

April Flowers for redOrbit.com - Your Universe Online New research, led by the University at Buffalo, is examining an important mystery surrounding climate change: How quickly do glaciers melt and grow in response to shifts in temperature. According to the study, published in Science, glaciers on Canada's Baffin Island expanded rapidly during a brief cold snap about 8,200 years ago. This discovery adds to a growing body of evidence that shows ice sheets reacted rapidly in the past to...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
