Scary Sea Levels

"About 20 percent of the ice in glaciers, on islands such as Ellesmere or Devon off northern Canada, could vanish by the end of the 21st century in a melt that would add 3.5 cm (1.4 inch) to global sea levels, they said."  Canadian glaciers are going, and scientists say that it is irreversible.  Now all we can do is plan how low lying cities and areas will cope with the rising sea levels.  The dark tundra that will be exposed from melting ice caps will then further the melting.  This is scary for cities such as Bangladesh, Shanghai, and even New York.  We have to start planning for this melt off now before it's too late.
