According to a report by PTI, over a third of the Antarctic's ice shelf area may be at risk of collapsing into the sea if global temperatures reach four degrees Celsius above pre-industrial levels, according to a study.

This discovery has raised an alarm about glacier collapse, which can lead to nearly three feet rise in the sea level.

The place where the glacier is in contact with the sea has been recorded as 2 degree celsius above the freezing temperature.

Reportedly, an underwater robot called Icefin made its way underneath the surface of the melting glacier and discovered the unusually warm temperature.

"Ice shelves are important buffers preventing glaciers on land from flowing freely into the ocean and contributing to sea level rise," said Ella Gilbert from the University of Reading in the UK.

The researchers noted that limiting temperature rise to two degrees Celsius rather than four degrees Celsius would halve the area at risk, and potentially avoid significant sea level rise

"The findings highlight the importance of limiting global temperature increases as set out in the Paris Agreement if we are to avoid the worst consequences of climate change, including sea level rise," said Gilbert
