Researchers say a massive two-thirds sized Manhattan void was found under a glacier in the Antarctic. The bag is a sign of "rapid decline" and just one of "some disturbing discoveries" made recently with respect to the glacier, NASA's Jet Propulsion Laboratory said in a Wednesday press release, "An important role in smelting." Pietro Milillo of the Jet Propulsion Laboratory, says, "As more heat and water gets under the glacier, it melts faster."
The growing cavity is in West Antarctica, at the foot of the Thwaites Glacier, which is about the size of Florida and has enough ice NASA is growing at an "explosive" rate, surprising researchers who had conducted a study that led the authority on the glacier.
"Underline the findings The need for more detailed observations of the undersides of the Antarctic glaciers when calculating how fast the global sea level in response to climate change will increase, "said NASA's Jet Propulsion Laboratory.
Jeff Berardelli, CBS News reports that the cavity is likely to be a significant finding as the West Antarctic ice sheet is considered one of the most unstable and vulnerable. Not only does it seem to melt at the edges of the ocean, it also infiltrates from below and warmer seawater.
NASA said the hole was large enough to hold 14 billion tons of ice, most of it melted in the last three years. Scientists say the glacier accounts for around four percent of global sea-level rise.
