Polar Science Center investigator Ian Joughin and Richard B. Alley of the Department of Geosciences at Pennsylvania State University were recently published in the journal Nature Geoscience.  Their article discusses the possibility of a large contribution to rising sea levels due to the melting of the West Antarctic Ice Sheet by global warming.  The full article is available here.
