This, along with melting glaciers and ice sheets in Greenland and Antarctica, drives sea levels higher over the long term. For the past 18 years, the U.S./French Jason-1, Jason-2 and Topex/Poseidon spacecraft have been monitoring the gradual rise of the world's ocean in response to global warming. http://phys.org/news233396609.html Space & Earth Wed, 24 Aug 2011 09:24:25 EST news233396609 (PhysOrg.com) -- A vast network of previously unmapped glaciers on the move from thousands of miles inland to the Antarctic coast has been charted for the first time by UC Irvine scientists. The findings will be critical to tracking future sea rise from climate change. http://phys.org/news232894541.html Space & Earth Thu, 18 Aug 2011 14:00:01 EST news232894541 During the last prolonged warm spell on Earth, the oceans were at least four meters – and possibly as much as 6.5 meters, or about 20 feet – higher than they are now. http://phys.org/news231082010.html Space & Earth Thu, 28 Jul 2011 14:40:01 EST news231082010 Stronger ocean currents beneath West Antarctica's Pine Island Glacier Ice Shelf are eroding the ice from below, speeding the melting of the glacier as a whole, according to a new study in Nature Geoscience. A growing cavity beneath the ice shelf has allowed more warm water to melt the ice, the researchers say—a process that feeds back into the ongoing rise in global sea levels. The glacier is currently sliding into the sea at a clip of four kilometers (2.5 miles) a year, while its ice shelf is melting at about 80 cubic kilometers a year - 50 percent faster than it was in the early 1990s - the paper estimates. http://phys.org/news228324328.html Space & Earth Sun, 26 Jun 2011 16:25:45 EST news228324328 In this field diary, Margarita Marinova takes us on a journey to Antarctica in order to test spacesuits Testing the suits in harsh environments on Earth can help future explorers, who will need protection when investigating Mars and other places in the Solar System. http://phys.org/news225366209.html Space & Earth Mon, 23 May 2011 10:43:44 EST news225366209 The Antarctic Peninsula has warmed rapidly for the last half-century or more, and recent studies have shown that an adjacent area, continental West Antarctica, has steadily warmed for at least 30 years, but scientists haven't been sure why. http://phys.org/news221659536.html Space & Earth Sun, 10 Apr 2011 13:05:58 EST news221659536 Researchers have teased ammonia of a carbon-containing meteorite from Antarctica, and propose that meteorites may have delivered that essential ingredient for life to an early Earth. http://phys.org/news218136978.html Space & Earth Mon, 28 Feb 2011 17:36:48 EST news218136978 Two Norwegian adventurers Monday said they held slim hopes of finding the three other members of their party alive, after their yacht went missing in a fierce Antarctic storm. http://phys.org/news218093972.html Space & Earth Mon, 28 Feb 2011 06:10:01 EST news218093972 Some scientists studying penguins may be inadvertently harming them with the metal bands they use to keep track of the tuxedo-clad seabirds, a new study says. http://phys.org/news214062593.html Biology Wed, 12 Jan 2011 14:20:01 EST news214062593 (PhysOrg.com) -- Lake Vostok, an untouched lake in Antarctica, is soon to be reached for the first time.
