1000-year Antarctic Peninsula climate reconstruction A new 1000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost ten-fold, and mostly since the mid 20th Century. Summer ice melt affects the stability of Antarctic ice shelves and glaciers. The research, published this week in the journal Nature Geoscience, adds new knowledge to the international effort that is required to understand the causes of environmental change in Antarctica and...

Antarctic Glacial Melt May Be Natural
2013-04-15 11:05:27

Brett Smith for redOrbit.com - Your Universe Online As the debate over climate change continues, so does the publication of studies that support or challenge the notion that human activity is the main driver of rising temperatures. According to a new study in“¯Nature Geoscience, the dramatic thinning of glaciers in Western Antarctica is due to natural variation, and cannot be attributed directly to carbon emissions. "If we could look back at this region of Antarctica in...

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...

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...


Word of the Day
ween
  • To think; to imagine; to fancy.
  • To be of opinion; have the notion; think; imagine; suppose.
The word 'ween' comes from Middle English wene, from Old English wēn, wēna ("hope, weening, expectation"), from Proto-Germanic *wēniz, *wēnōn (“hope, expectation”), from Proto-Indo-European *wen- (“to strive, love, want, reach, win”).
