More than a third of the Antarctic ice shelf would collapse into the ocean if global temperatures
Scientists have conducted the most detailed research onpredicting how vulnerable the ice will become in the area. The researchers also modeled at what point part of the Antarctic will collapse into the ocean if the temperature continues to rise.
Researchers have found that 34% of the area of allthe Antarctic ice shelf (about half a million square kilometers) would be at risk of destabilization with 4 ° C warming. If the warming does not exceed 2 ° C, then this will avoid a significant rise in the ocean level.

The researchers also said that the Larsen Glacier, the largest remaining ice shelf on the peninsula, from which iceberg A68 broke in 2017, will collapse first.
“Glaciers are important buffers thatprevent uncontrolled sea level rise. When they break, it's like a giant cork being removed from a bottle, allowing a huge amount of water to flow into the sea, the scientists noted. “We know that when melted ice accumulates on the surface of ice shelves, it can cause them to crack and collapse spectacularly. Global warming plays a big role in this.”
