Ice shelf protecting Antarctic glacier is breaking up faster

 


A critical Antarctic glacier is looking more vulnerable as satellite images show the ice shelf that blocks it from collapsing into the sea is breaking up much faster than before and spawning huge icebergs, a new study says.

The Pine Island Glacier's ice shelf loss accelerated in 2017, causing scientists to worry that with climate change the glacier's collapse could happen quicker than the many centuries predicted. The floating ice shelf acts like a cork in a bottle for the fast-melting glacier and prevents its much larger ice mass from flowing into the ocean.

That ice shelf has retreated b...
