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...

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...

The Forming Of Antarctica's Hidden Fjords
2013-03-06 13:41:41

University of Arizona Antarctica's topography began changing from flat to fjord-filled starting about 34 million years ago, according to a new report from a University of Arizona-led team of geoscientists. Knowing when Antarctica's topography started shifting from a flat landscape to one with glaciers, fjords and mountains is important for modeling how the Antarctic ice sheet affects global climate and sea-level rise. Although radar surveys have revealed a rugged alpine landscape...

Algae Fossils Help Unlock Climate Change Secrets
2013-01-23 10:46:06

April Flowers for redOrbit.com - Your Universe Online One of the fastest warming regions on the planet — and the fastest warming part of the Southern Hemisphere — is the western Antarctic Peninsula. This warming has been the subject of scientific debate, especially in light of recent instrumental records of both atmospheric and oceanic warming from the region. Holding an equivalent of 5 meters of global sea level rise locked in ice, the Antarctic ice sheet is becoming...

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...

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...

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...

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...

Antarctica is the Earths southernmost continent; it contains the geographic South Pole. It’s situated in the Antarctic area of the Southern Hemisphere, almost completely south of the Antarctic Circle, and is bordered by the Southern Ocean. It’s the fifth-largest continent at 5.4 million sq miles. On average, it is the driest, coldest, and windiest continent as well as having the highest average elevation of all the continents. Considered a desert, the annual precipitation is only 8...
