Ice Shelf Critical Glacier Protection Breaking Up Quickly

A critical Antarctic glacier is looking more vulnerable as satellite imagery blocks the ice shelf from collapsing into the ocean, giving giant icebergs waking up much faster than before laying eggs, a new study says.
The damage to the ice shelf of the Pine Island Glacier accelerated in 2017, causing scientists to think that with climate change the prediction of the glacier’s collapse could happen faster than many centuries. The floating ice shelf quickly melts and one bottle for glaciers acts like a cork and prevents its much larger ice mass from flowing into the ocean.

That ice shelf, which has been lagging behind by 12 miles (20 kilometers) between 2017 and 2020, according to a research progress on Friday, was caught in a time lapse video from a European satellite crumbling shelf that takes pictures every six days.
“You can just tear things up,” said Ian Zaffin, lead author of a study by a glycologist in Washington. “So it almost looks like speeding up is weakening the glacier itself and so far we’ve probably lost 20% of the original shelf.
There were three major holiday events between 2017 and 2020, more than 5 miles (8 kilometers) long and 22 miles (36 kilometers) wide, after which littler pieces made lots of split icebergs, Joughin said. There were also many small breakups
