Antarctic High Ridge Gets Distinction As Coldest Place On Earth
2013-12-10 09:03:50

[ Watch the Video: Coldest Place On Earth Is The East Antarctic Plateau ] redOrbit Staff & Wire Reports - Your Universe Online If you think it’s cold where you live, consider this: NASA satellites have just discovered the chilliest place on Earth, where temperatures can plummet to minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius). This “glad I don’t live there” location is a high ridge in Antarctica on the East Antarctic Plateau, where temperatures in several...

Global Warming Could Explain Exponential Sea Ice Growth
2013-09-18 12:28:55

Michael Harper for redOrbit.com - Your Universe Online In a bit of strange and unprecedented good news, it was recently discovered Antarctic sea ice is growing at record rates. This is definitely odd, of course, because the air and the oceans have been getting warmer in the area. There is now more sea ice in Antarctica than there had been in the 1970s, a data point which University of Washington (UW) researcher Jinlun Zhang wanted to unpack and investigate. According to his National...

West Antarctica Deglaciation Began Much Earlier Than Thought

Lawrence LeBlond for redOrbit.com - Your Universe Online One of the deepest ice cores ever drilled in Antarctica is revealing some interesting evidence about the southern continent’s turbulent past and the role Earth’s orbit played in the history of the ice ages. Scientists have known for more than a century that ice ages come and go due to the wobbling of the Earth as it orbits the sun. Increases in the intensity of summer sunlight in the Northern Hemisphere melted the ice sheets...

Antarctic Ice Shelf Collapse Has Been Occurring For 600 Years, Manmade Climate Change Is Now Adding To Problem
2012-08-23 10:53:35

Lawrence LeBlond for redOrbit.com - Your Universe Online The Antarctic Peninsula has been continually shrinking for centuries, since long before the Industrial Revolution, according to an international team of researchers. However, rapid warming over the past 100 years has been unusual and, if it continues, the ice shelf could be on par for a complete collapse. Temperatures in the Antarctic Peninsula began rising around 600 years ago, occurring naturally. This was long before manmade...

Scientists have created a detailed map called BEDMAP of Antarctica's rock bed that lies underneath its icy surface. The map gives a view of the landscape beneath the ice, and incorporates decades of survey data acquired by planes, satellites, ships and even people on dogsleds. In the map, the highest elevations are marked in red/black, while the light blue color shows the extent of the continental shelf.  The lowest elevations are dark blue, some of which lie below today's seal...

Rutgers' Oscar Schofield and five colleagues from other institutions have published in Science, calling for expanded ocean-observing in the Antarctic, particularly in the Western Antarctic Peninsula, or WAP. This mountainous arm of the continent stretches north toward South America. In their review paper, the co-authors, who have done research in the Antarctic, often together, argue that research in this region is imperative: The WAP's climate, they say, is changing faster than the climate...

Marco Tedesco Says Record Low Resulted From Simultaneous Positive Phases for Two Climate Drivers The 30-year record low in Antarctic snowmelt that occurred during the 2008-09 austral summer was likely due to concurrent strong positive phases for two main climate drivers, ENSO (El Niño - Southern Oscillation) and SAM (Southern Hemisphere Annular Mode), according to Dr. Marco Tedesco, Assistant Professor of Earth & Atmospheric Sciences at The City College of New...

A major scientific report released on Tuesday showed that rapid ice loss in West Antarctica will likely contribute heavily to a projected sea level rise of up to 4.5 feet by 2100, AFP reported. For years scientists believed that most of Antarctica's continent-sized ice sheet was highly resistant to global warming, and that the more vulnerable West Antarctic ice block would remain intact for thousands of years to come. But according to the review by more than 100 experts on the Scientific...

Most comprehensive seabed image of Amundsen Sea Embayment Motorway-sized troughs and channels carved into Antarctica's continental shelves by glaciers thousands of years ago could help scientists to predict future sea-level rise according to a report in the journal Geology this month (May). Using sonar technology from onboard ships, scientists from British Antarctic Survey (BAS) and the German Alfred Wegener Institute (AWI) captured the most extensive, continuous set of images of the seafloor...

A hole in the ozone has resulted in a growth of Antarctic sea ice over the past 30 years, according to a report released on Tuesday. Scientists from the British Antarctic Survey (BAS) and NASA reported the ozone hole has resulted in changing weather patterns that have caused a small rise in the amount of Antarctic sea ice, while Arctic sea ice has seen a dramatic loss. Sea ice is a crucial part of the Earth's ecosystems. It acts as a reflector against the sun's heat, and provides a habitat...
