Ice melting in the western Antarctic at an 'unstoppable' pace, warn NASA scientists

Agence France-Presse: Ice is melting in the western Antarctic at an "unstoppable" pace, scientists said Monday, warning that the discovery holds major consequences for global sea level rise in the coming decades. The speedy melting means that prior calculations of sea level rise worldwide made by the Intergovernmental Panel on Climate Change will have to be adjusted upwards, scientists told reporters. "A large sector of the West Antarctic ice sheet has gone into a state of irreversible retreat. It has passed the...

NASA spots worrisome Antarctic ice sheet melt
2014-05-12 21:44:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: The huge West Antarctic ice sheet is starting a glacially slow collapse in an unstoppable way, two new studies show. Alarmed scientists say that means even more sea level rise than they figured. The worrisome outcomes won't be seen soon. Scientists are talking hundreds of years, but over that time the melt that has started could eventually add 4 to 12 feet to current sea levels. A NASA study looking at 40 years of ground, airplane and satellite data of what researchers call "the weak underbelly...
NASA spots worrisome Antarctic ice sheet melt
2014-05-12 21:40:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: It's likely because of man-made global warming and the ozone hole which have changed the Antarctic winds and warmed the water that eats away at the feet of the ice, researchers said at a NASA news conference Monday. "The system is in sort of a chain reaction that is unstoppable," said NASA glaciologist Eric Rignot, chief author of the NASA study in the journal Geophysical Research Letters. "Every process in this reaction is feeding the next one." Curbing emissions from fossil fuels to slow climate...
NASA creates star dust here on Earth for the first time: Carl Sagan would be proud
2014-05-12 20:52:56| Extremetech
Here on Earth, at NASA's Ames Research Center in California, scientists have created stardust -- or more accurately, they've recreated the dust that forms in the outer atmosphere of a dying red giant star. Out there in space, over millions of years, this interstellar dust gathers together into a nebula and goes on to coalesce into planets and other stars. Down here on Earth, of course, NASA isn't trying to create its own planets (not yet, anyway) -- no, they have the much more humble undertaking of trying to better understand how the universe and its trillions of planets and stars evolved over the last 14 billion years.
NASA Uses MicroTCA Architecture for Space Network Ground Segment Sustainment Project (SGSS)
2014-05-05 06:00:00| Industrial Newsroom - All News for Today
Henderson, NV — NASA is upgrading its ground terminals to modernize the communications infrastructure and provide new capabilities for their customers. The architecture chosen for the majority of their system is MicroTCA (ìTCA) for its high performance, system management and failover capabilities, and COTS module diversity. The ground terminals are used in conjunction with several satellites supporting over 20 spacecraft, including the International Space Station, the Hubble Space ...This story is related to the following:Communication Systems and EquipmentSearch for suppliers of: Telecommunications Equipment
