New Model Assesses Extent Of Sea Level Rise By 2100
2013-01-07 09:01:17

Lawrence LeBlond for redOrbit.com - Your Universe Online Two professors with the Intergovernmental Panel on Climate Change (IPCC) have taken on a new approach to assess future sea level rise due to the world´s melting ice sheets. Their study, published this week in Nature Climate Change, is the first of its kind to use structured expert elicitation (EE) along with an approach that mathematically pools other experts´ opinions to gain a clear picture on ice sheet melting....

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...

Significant Technological Milestones Reached By Trio of Complex Antarctic Science Projects
2012-12-21 13:38:46

National Science Foundation Drilling-related breakthroughs funded by NSF expected to advance "frontier science" in a variety of disciplines Three very large-scale, National Science Foundation-funded Antarctic science projects--investigating scientifically significant subjects as varied as life in extreme ecosystems, the fate of one of the world's largest ice sheets and the nature of abrupt global climate-change events--have recently each reached important technological milestones that...

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...

Lee Rannals for redOrbit.com - Your Universe Online Scientists believe they have discovered a hidden rift valley that may be contributing to ice loss in West Antarctica. University of Aberdeen and British Antarctic Survey (BAS) experts made the discovery below Ferrigno Ice Stream, which is a very remote region that has only been visited once before. The team has reveled that the ice-filled ancient rift basin is connected to the warming ocean, which impacts ice flow and loss. The...

Antarctic Octopus Provides Clues To Ice Sheet Collapse
2012-05-10 08:34:34

Brett Smith for Redorbit.com A joint team of UK and Australian researchers has found that two separate groups of Antarctic octopuses, from the Ross and Weddell seas on different sides of the continent, are almost genetically identical. This suggests that the two seas, which are now separated by the West Antarctic Ice Sheet, were once joined together, possibly a result of the partial collapse of the continental ice sheet. Researchers analyzed the genes of 450 Turquet's octopuses...

Novel Method To Identify Sources Of Global Sea Level Rise
2012-04-24 11:08:34

As the Earth's climate warms, a melting ice sheet produces a distinct and highly non-uniform pattern of sea-level change, with sea level falling close to the melting ice sheet and rising progressively farther away. The pattern for each ice sheet is unique and is known as its sea level fingerprint. Now, a group of geophysicists from the University of Toronto, Harvard and Rutgers Universities have found a way to identify the sea level fingerprint left by a particular ice sheet, and possibly...

Today the U.S. National Research Council released a synthesis of reports from thousands of scientists in 60 countries who took part in the International Polar Year (IPY) 2007-08, the first in over 50 years to offer a benchmark for environmental conditions and new discoveries in the polar regions. University of Massachusetts Amherst geosciences researcher and expert in the paleoclimate of the Arctic, Julie Brigham-Grette, co-chaired the NRC report, "Lessons and Legacies of the IPY 2007-08"...

But projections for increase today still loom large The seas are creeping higher as the planet warms. But how high will they go? Projections for the year 2100 range from inches to several feet, or more. The sub-tropical islands of Bermuda and the Bahamas contain important sites where researchers have gone looking for answers; by pinpointing where shorelines stood on cliffs and reefs there during an extremely warm period 400,000 years ago, they hope to narrow the range of global sea-level...

Ambitious Antarctic Expedition In The 'Deep-field' Complete
2012-01-16 04:23:28

A team of four British Antarctic Survey (BAS) engineers has returned to the UK after completing a grueling journey to one of the most remote and hostile locations on the planet to put in place equipment and supplies for an ambitious project later this year. Enduring temperatures of minus 35°C the Subglacial Lake Ellsworth ℠Advance Party´ has successfully paved the way to explore an ancient lake buried beneath 3 km of Antarctic ice. A powerful ℠tractor-train´ towed...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
