'Unprecedented,' 'Gobsmacked', 'Unbelievable': Changes in Antarctica's sea ice could have dramatic impacts, says climate scientist Edward DoddridgeIn 1898, the crew of the first scientific expedition to Antarctica became trapped inside sea ice around the southernmost continent. Much of that once thick ice is dwindling, says polar researcher Edward Doddridge.
