Study Raises New Concern About Global Warming
A study published in Nature says global warming could disintegrate the vast ice Antarctic ice sheet sooner than originally thought. That would mean a 3-foot sea level rise by the year 2100 and a 50-foot rise by the year 2500, something that would endanger coastal cities. Here & Now’s Jeremy Hobson speaks with Richard Alley, a professor at Pennsylvania State University and one of the study’s co-authors.
