Sea level rise is already happening and having an impact.  Look at Miami Beach and Key West at high tide on a full moon.  The potential changes to be wrought by rising waters affect our whole way of life.  It is not a new phenomenon but it hasn't occurred in recent times.  It will impact our fresh water supply, our solid waste disposal, sea level nuclear power plants, our flora and fauna.  Just start thinking about it.  What's the solution?  Do we rebuild on high ground?  Do we put our coastal cities on stilts?  What is your idea?  Google sea level rise and see what you find.  We need to address this now.
