Antarctica's Doomsday Glacier is hanging

Thwaites Glacier, also known as "Doomsday Glacier" due to its ability to raise sea level by several feet, is said to be hanging "by its fingernails."

According to a study published in Nature Geoscience, scientists discovered that the base of the underwater glacier is eroding as a result of global warming.

"Thwaites is really biting its nails today," said co-author and marine geophysicist Robert Larter.

once the glacier retreats beyond a shallow rim at its bottom, we should expect to see big changes on small time scales in the future - even from year to year."

The Thwaites glacier in West Antarctica is roughly the size of Florida and could raise sea levels by about 16 feet if it melted and fell into the sea, which scientists believe is likely.

According to a new study published on Monday, Antarctica's "Doomsday Glacier" is hanging "by its fingernails."

According to lead author Alistair Graham, researchers have been tracking glacier stagnation since "as recently as the mid-twentieth century."
