The Permafrost Timebomb?
June 13, 2013 | NASA
Over hundreds of thousands of years the Arctic permafrost has accumulated an enormous store of organic carbon. As it thaws from climate change the plant debris will decay and carbon dioxide and methane will be release into the atmosphere. Permafrost contains at least 4x more carbon than fossil fuel burning has produced since 1850.
Topography Below Antarctic Ice
June 10, 2013 | British Antarctic Survey
"Scientists at the British Antarctic Survey have been working with a host of international collaborators to present the most detailed map yet of Antarctica’s landmass. [...] The map allows scientists to analyse, in much greater detail, the bed below the Antarctic ice sheet." Quoted from the British Antarctic Survey press release.
Plumbing Under the Greenland Ice Sheet
August 27, 2013 | National Science Foundation
"Scientists' understanding of how Greenland Ice Sheet melt water travels in passages along the bedrock below fails to account for some key processes. This, in turn may be affecting their assessment of how ice sheets respond to climate change." Quoted from the National Science Foundation press release.
