[IPRNmail] Old ice in Arctic vanishingly rare

The animation of the National Oceanic and Atmospheric Administration (NOAA) in shows remarkably as the thickness of the Arctic sea ice has changed since 1987.

Decades ago, the majority of the Arctic's winter ice pack was made up of thick, perennial ice. Today, very old ice is extremely rare. WATCH this animation tracking the relative amount of ice of different ages from 1987 through early November 2014. Read a more detailed description at http://1.usa.gov/1ymZhuK.
