Scientists Drill through 2,400 Feet of Antarctic Ice for Climate Clues
2015-01-16 15:43:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: Scientists have drilled into one of the most isolated depths in all of the world's oceans: a hidden shore of Antarctica that sits under 740 meters of ice, hundreds of kilometers in from the sea edge of a major Antarctic ice shelf. Humans have never glimpsed this place; reaching it required seven years of planning and 450 tonnes of fuel and gear. But understanding what is happening down there, so far from human view, will be crucial for predicting the future fate of Antarctica's ice sheets amid rising...

BBC: Aerial photos from the 1940s and 1950s are being used to probe the climate history of the Antarctic Peninsula. UK scientists are comparing the images with newly acquired data sets to assess the changes that have occurred in some of the region's 400-plus glaciers. The old and modern information has to be very carefully aligned if it is to show up any differences reliably. And that is a big challenge when snow and ice obscure ground features that might otherwise act as visual anchors. But...

If global warming is reality why is Antarctic ice growing?

Business Times: It is one of the greatest puzzles in the science of climate change, and has been used by skeptics to cast doubt on global warming: Why, when the world is getting hotter, is the Antarctic getting colder? Now, a scientist thinks she may have uncovered the answer. Cecilia Bitz, an atmospheric scientist from the University of Washington in Seattle, believes that oceanic currents are taking heat away from Antarctica and carrying it north, reports the Sunday Times. As scientists predicted the Arctic,...

Antarctic ice shelf being eaten away by sea

Science: This year, scientists reported alarming news about the huge continental ice sheet covering the western portion of Antarctica: It's headed for collapse, due to rapid melting of some of its buttressing ice shelves. When it does, global sea levels will rise by several meters. It has long been suspected that warm ocean waters at the base of those floating ice shelves are responsible for hurrying things along. But with scant data from the waters around Antarctica, that has been difficult to prove. Now,...
Warmer seas could cause faster melting of Antarctic ice leading to rising sea levels, says study

Guardian: Warming water under Antarcticas ice shelves risks ice melting that could lead to a worrying rise in global sea levels, research has shown. Loss of the Antarctic ice shelves, which extend from the southern polar land mass over the underwater continental shelf, are likely to result in the glaciers behind them flowing more rapidly into the sea. That would feed more melting ice into the oceans, pushing up sea levels. Total melting of the West Antarctic ice sheet, which is close to the regions...
