This 2016 NASA image shows Getz Ice Shelf from 2016's Operation Icebridge in Antarctica. According to a new study published Monday, January 14, 2019, in the Proceedings of the National Academy of Sciences, Antarctica melts more than six times faster than it did in the 1980s.
SALT LAKE CITY – NASA says a double ash as New York City will break off an ice shelf in Antarctica, USA Today reports.
The researchers noticed a giant crack in the middle of the Brown Ice Shelf in Antarctica.
How it happens Two cracks in the shelf will lead to massive disruption. The Halloween crack, which was first shown in October 2016, will move east.
The other crack breaking north has been fine for 35 years according to CNN. But the second crack began to accelerate about 2.5 miles a year. When the cracks meet, the iceberg is born.
When the tap expands enough, it will create an iceberg measuring about 660 square kilometers, according to USA Today. New York City measures 302 square kilometers.
"We don't have a clear picture of what drives the shelf shifts and retreats through calving," said Chris Shuman, a glaciologist with NASA and the University of Maryland Baltimore County in a statement. "The likely future loss of ice on the other side of Halloween Crack suggests that there is more instability."
NASA did not confirm when it would happen. The agency said it is "ready" to do, CNN reports.
The Brown Ice Shelf is currently out of the Weddell Sea just south of South America, according to CNN.
