    Antarctic ice is melting, adding to the inexorable rise in global sea levels, endangering millions of lives and whole economies, leading British scientists said on Monday. But while the effect is well known after years of monitoring from land and space, the reasons for the sea warming are not. There has been a net loss of mass in Antarctic ice as the gain in landmass was more than offset by loss on the coasts.

  • February 7, 2005 - Antarctica's Ice Seems To Be Safe ... - USA Today
    Chilean glaciologists using radar developed at the University of Kansas have found that the West Antarctic Ice Sheet may be thicker than previously thought. In fact it may be hundreds of feet thicker in some areas. They warn that the deeper the ice, the more potential impact on sea level rise should it melt. They say there is some instability in West Antarctica though the temperature seems to be holding steady or cooling in other parts of the continent. Radar developed by the PRISM scientists and the Remote Sensing Lab at the University of Kansas was involved in this study!

    Scientists from the British Antarctic Survey report that over 13,000 sq. kilometers of sea ice has been lost around the Antarctic peninsula over the past 50 years. This loss is allowing the glaciers to flow into the ocean many times faster than was estimated in most sea-level rise models. PRISM Principal Investigator, Dr. Prasad Gogineni, was invited to give a talk to the British Antarctic Survey on the KU radar work. See similar story from TimesOnline - Britain.
