WELLINGTON, New Zealand (AP) - An ice sheet in Antarctica that is the world's largest — with enough water to raise global sea levels by 200 feet — is relatively stable and poses no immediate threat, according to new research.
While studies of the Greenland and West Antarctic ice sheets show they are both at risk from global warming, the East Antarctic ice sheet will "need quite a bit of warming" to be affected, Andrew Mackintosh, a senior lecturer at Victoria University, said Wednesday.
The air over the East Antarctic ice sheet, an ice mass more than 1,875 miles across and up to 2.5 miles thick centered on the South Pole, will remain cold enough to prevent significant melting in the near future, the New Zealand-led research shows.
