Scientists pinpoint polar catastrophe

They say Antarctica was hit by meltdown about 12 million years ago

SYRACUSE, N.Y. - A 30-mile maze of canyons in Antarctica was carved out of bedrock by the catastrophic draining of subglacial lakes during global warming 12 million to 14 million years ago, according to university researchers who warn that a similar event today could have serious environmental consequences.

Although scientists have previously theorized that the Labyrinth region in southern Victoria Land was created by water released from lakes that had formed under glaciers, researchers at Syracuse University and Boston University say they found geological evidence to bracket the timing of the last major flooding and link it to a global warming trend at the time.

The Labyrinth is a network of ice-free bedrock channels and scoured terrain emerging from beneath the East Antarctic Ice Sheet. Researchers say the terrain was carved by the catastrophic draining of subglacial lakes during global warming between 12 million and 14 million years ago.
