"Disturbing" discovery: Giant hole found under Antarctica glacier

JANUARY 31, 2019

Researchers say a massive cavity the size of two-thirds of Manhattan was found under a glacier in Antarctica. The pocket is a sign of "rapid decay" and just one of "several disturbing discoveries" made recently regarding the glacier, NASA's Jet Propulsion Laboratory said in a news release Wednesday.

"[The size of] a cavity under a glacier plays an important role in melting," said Pietro Milillo of the Jet Propulsion Laboratory. "As more heat and water get under the glacier, it melts faster."

The growing cavity sits in West Antarctica at the bottom of Thwaites Glacier, which is about as big as Florida and contains enough ice to contribute more than 2 feet to sea level rise, NASA said. It is growing at an "explosive" rate that surprised researchers conducting a study the agency led on the glacier.

rate then anyone ever imagined. We should be much more concerned about how we are going to keep the seas from advancing on our borders.

when sea level is two feet higher.

even a modest cat 1 or 2 hurricane could cause catastrophic destruction to populated coastal areas.
