West Antarctic Ice Sheet ‘Could Be More Stable than Thought’
Whether global warming may cause the giant West Antarctic Ice Sheet to melt and raise sea-levels by several metres is one of the most contested debates in climate science. (more…)

Greenland’s Glaciers Double in Speed
The contribution of Greenland to global sea level change and the mapping of previously unknown basins and mountains beneath the Antarctic Ice Sheet are highlighted in a new film released by Cambridge University this morning.
The work of glaciologist Professor Julian Dowdeswell, Director of Cambridge University’s Scott Polar Research Institute, is the focus of This Icy World, the latest film in the University’s Cambridge Ideas series. (more…)
NSF Signs $34.5-million Operating Agreement With University Of Wisconsin as Antarctic Neutrino Detector Nears Completion
The National Science Foundation has signed a five-year, $34.5-million agreement with the University of Wisconsin-Madison to operate a unique telescope–a cubic kilometer in volume–buried in the Antarctic ice sheet between 1,400 meters and 2,400 meters deep.
The collaborative agreement covers the cost of operating the IceCube Neutrino Observatory, located in the ice under the U.S. Amundsen-Scott South Pole Station. The observatory records the rare collisions of neutrinos, elusive sub-atomic particles, with the atomic nuclei of the water frozen into ice. Neutrinos come from the sun, cosmic rays interacting with the Earth’s atmosphere, and dramatic astronomical sources such as exploding stars in the Milky Way and other distant galaxies. Trillions of neutrinos stream through the human body at any given moment, but they rarely interact with regular matter, and researchers want to know more about them and where they come from. (more…)
