New Map of Antarctica Provides Clearest Glimpse of Subglacial Continent
2013-06-07 16:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: NASA Goddard Space Flight Center Antarctica's subglacial terrain British scientists have unveiled the most detailed topographical map available yet of Antarctica, a vast dataset that provides a penetrating 3-D view of the frozen continent down to the bedrock level and could offer key insights into how it will respond to climate change. Based on millions of measurements collected over several decades, the British Antarctic Surveys Bedmap2 project illustrates the continent with a level of clarity...

This is what an ice-free Antarctica looks like
2013-06-06 12:13:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: Check out the most detailed map of a continent never truly seen by human eyes: the de-iced surface of Antarctica. By virtually peeling back the frozen ice sheet and studying the land beneath, researchers can get a better sense of how the southern pole of our planet could react to climate change. Bedmap2 was created by the British Antarctic Survey, and used decades of data to produce this detailed view of the frozen continent. NASAs contribution to the dataset includes surface measurements from...

Why Canada should back Antarctica North
2013-05-18 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Globe and Mail: Another kind of Canadian government would take this opportunity as Arctic Council chair to lead a diplomatic effort to demilitarize the region, to make it a northern Antarctica where, by international treaty, military activities are banned. Of course, the Arctic Council alone couldn't bring about demilitarization since it has no such power, but it could become an important place to put the issue on the international agenda. Canada should borrow a slogan from someone Americans love - Ronald Reagan,...

Antarctica Peninsula Climate Reconstruction
2013-04-19 13:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: The Antarctic Peninsula is the northernmost part of the mainland of Antarctica. It is the section closest to another continent (South America). A new 1000-year Antarctic Peninsula climate reconstruction shows that summer ice melting has intensified almost ten-fold, and mostly since the mid 20th Century. Summer ice melt affects the stability of Antarctic ice shelves and glaciers. The research, published in the journal Nature Geoscience, adds new knowledge to the international effort that is required...
