Past Big Melts in Antarctic May Provide Glimpse into Future

icebergNew studies on past melts in the Antarctic may help scientists predict future melting patterns.  Based on an examination of soil cores far below the surface of the Ross ice shelf, one study suggests that the West Antarctic ice sheet collapsed periodically between 3 and 5 million years ago, adding more than 16 feet to global sea level. Also, a second study using new computer models suggests that warmer waters nearby attacked the ice from below, triggering those collapses. 

“What we’re seeing in the past would lead us to believe that we are on track for losing parts of the West Antarctic ice sheet,” said Tim Naish, director of the Antarctic Research Centre at Victoria University in New Zealand.  For more information, see the Associated Press article here.
