'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.

'2023 just blew everything off the charts': Antarctic sea ice hits troubling low for third consecutive yearSea ice extent in Antarctica is vital for keeping ice on the continent and sea levels low. But its dwindling extent could mean the continent has shifted to a new regime, with global ramifications.

Collapse of the West Antarctic ice sheet is 'unavoidable,' study findsBritish Antarctic Survey researchers have found that the rate at which ice is melting and contributing to sea level rise will accelerate in the next century, regardless of actions to limit greenhouse gas emissions.
