One of the World's Longest Living Icebergs Isn't Just Melting; It's Turning Blue

Iceberg A-23A, one of the longest-lived icebergs ever tracked, is rapidly melting and turning blue as it drifts through the Southern Ocean. Originating from Antarctica's Filchner Ice Shelf in 1986, it has shrunk from 1,500 square miles to 456 square miles. Scientists predict its collapse within days or weeks due to warmer waters and seasonal conditions.
