April Flowers for redOrbit.com - Your Universe Online A research team led by professors at the University of California Santa Barbara (UCSB) has revealed that, contrary to popular belief, an ice sheet on West Antarctica existed 20 million years earlier than previously thought. These results, published in Geophysical Research Letters, mark a paradigm shift for our understanding of the Earth’s great global ice sheets. Ice sheets first grew on the West Antarctic subcontinent around 34...

The East Antarctic ice sheet, once unaltered by global warming, has swiftly melted since 2006 and could increase sea levels, says a new study. Available in a recent issue of Nature Geoscience, the same research indicates that the West Antarctic ice sheet is also melting rapidly. Scientists are concerned that higher global temperatures could cause a quick collapse of West Antarctica, which has enough frozen water to raise the global ocean watermark by 16 feet. In 2007 the UN Intergovernmental...

Lakes in Antarctica, concealed under miles of ice, require scientists to come up with creative ways to identify and analyze these hidden features. Now, researchers using space-based lasers on a NASA satellite have created the most comprehensive inventory of lakes that actively drain or fill under Antarctica's ice. They have revealed a continental plumbing system that is more dynamic than scientists thought."Even though Antarctica's ice sheet looks static, the more we watch it, the more we see...

New research by scientists in Britain and China reveals evidence of how the East Antarctic ice sheet initially formed. The work provides a snapshot of terrain that has lain hidden miles beneath the ice for millions of years, when rivers ran through mountain valleys that were oddly similar to the modern European Alps. The scientists used radar to map an area of the Gamburtsev mountains, believed to be where the ice originated. The region would have been cold enough to support the...

The potential contribution to sea level rise from a collapse of the West Antarctic Ice Sheet (WAIS) have been greatly overestimated, according to a new study published in the journal Science. Scientists estimate global sea level would rise 3.3 metres, not five or six, as previously thought. The Atlantic and Pacific seaboards of the US, even in the case of a partial collapse, would experience the largest increases, threatening cities such as New York, Washington DC and San Francisco.Long...

U.S. climatologists say they've determined the West Antarctic ice sheet changes rapidly over the eons, most influenced by ocean temperatures. Researchers at Pennsylvania State University and the University of Massachusetts said their findings were based on modeling 5 million years of changes in the ice sheet. We found that the West Antarctic ice sheet varied a lot, collapsed and regrew multiple times over that period, said Penn State senior scientist David Pollard. The ice sheets in our model...

Two new reports published in the journal Nature illustrate possible flooding due to climate change and a meltdown of the massive West Antarctic ice sheet. In one study, researchers used soil cores below the Ross ice shelf to show that the massive melt took place between 3 million and 5 million years ago. That collapse amounted to an increase of more than 16 feet to global sea level, researchers noted. "What we're seeing in the past would lead us to believe that we are on track for losing...

Scientists said on Tuesday that Antarctica's ice is covering up jagged mountains the size of the Alps, providing new clues about the vast ice sheet that will raise world sea levels if even a fraction of it melts, Reuters reported. First detected by Russian scientists 50 years ago at the heart of the East Antarctic ice sheet using radar and gravity sensors, the experts made the first detailed maps of the Gamburtsev subglacial mountains. Fausto Ferraccioli, a geophysicist at the British...

A group of environment ministers landed on a remote corner of Antarctica on Monday to learn more about how the melting continent may threaten the Earth. The parka-clad representatives from more than twelve nations, including the U.S., China, Britain and Russia, were to meet scientists from the U.S. and Norway who were arriving after the last leg of a two-month, 1,400-mile trip over the ice from the South Pole. The group will gain "hands-on experience of the colossal magnitude of the Antarctic...

Scientists from the U.S., U.K. and Australia have teamed up to explore two of the last uncharted regions of Earth, the Aurora and Wilkes Subglacial Basins, immense ice-buried lowlands in Antarctica with a combined area the size of Mexico. The research could show how Earth's climate changed in the past and how future climate change will affect global sea level. Scientists believe the barely observed Aurora Subglacial Basin, which lies in East Antarctica, could represent the weak underbelly of...
