Antarctic Melt And Calls For Action (Tom Ashbrook, On Point)

The latest news from Antarctica is deeply sobering, and will be for a long time.  A great ice sheet there, melting.  That melt, unstoppable.  Painful sea rise will follow.  Climate change is deeply implicated.  And there are more dominoes poised to fall.  More glaciers and ice sheets poised to melt on a warming planet.  Climate scientist James Hansen says if we ever needed an urgent prompt to action, this is it.  He wants a carbon tax, that would kick up the price of fossil fuels, discourage their use, encourage alternatives.  This hour On Point:  a hellish melt, and the fresh call for a carbon tax.
