If you live in New York, London or any other major settlement close to the coast, you might want to start teaching your grandchildren how to build an ark.
Scientists have warned that a major flood will render several of the world’s greatest cities uninhabitable within a century.
Researchers claimed the West Antarctic Ice Sheet is “breaking apart from the inside out,” meaning that the sea will definitely rise by up to 10 feet.
“We may see a significant collapse of West Antarctica in our lifetimes.”
In 2013, a gigantic rift began forming within a valley in the ice of the Pine Island Glacier.
Then, in 2015, a 225-square-mile iceberg broke off and floated away.
Howat said this could indicate that the massive slab of ice was being eaten away from the inside out.
“Rifts usually form at the margins of an ice shelf, where the ice is thin and subject to shearing that rips it apart,” he added.
“However, this latest event in the Pine Island Glacier was due to a rift that originated from the center of the ice shelf and propagated out to the margins.”
“This implies that something weakened the center of the ice shelf, with the most likely explanation being a crevasse melted out at the bedrock level by a warming ocean.”
The ice sheet has previously been described as an “awakened giant” and is mostly made up of glaciers sitting on top of a layer of bedrock.
If it melts, it would add vast amounts of water into the oceans, sending sea levels rocketing to dangerous heights.
“The really troubling thing is that there are many of these valleys further up-glacier,” Howat added. “If they are actually sites of weakness that are prone to rifting, we could potentially see more accelerated ice loss in Antarctica.”
