World's biggest iceberg could be on collision course with Antarctic penguin island: "Game of Thrones-esque"

The world's biggest iceberg -- three time the size of New York City -- could drift towards a remote island where a scientist warns it risks disrupting feeding for baby penguins and seals.

The gigantic wall of ice is moving slowly from Antarctica on a potential collision course with South Georgia, a crucial wildlife breeding ground in the South Atlantic.

Satellite imagery suggested that unlike previous "megabergs," this rogue was not crumbling into smaller chunks as it plodded through the Southern Ocean, Andrew Meijers, a physical oceanographer at the British Antarctic Survey, told AFP on Friday.
