Several large glaciers in the West Antarctic are thinning at a dramatic rate and one of them could disappear in as little as 150 years if the current trend continues, according to new findings announced at a briefing at the AGU Fall Meeting in December in San Francisco. California

Using satellite radar altimetry and satellite radar interferometry, Andrew Shepherd, a research fellow at the Centre for Polar Observation and Modeling at University College London, studied the Pine Island,Thwaites, and Smith glaciers, which are the principal ice drainage channels for the Amundsen Sea sector of the West Antarctic Ice Sheet.
