London, April 2 : Pine Island Glacier a region of fast-flowing ice draining in West Antarctica may cross tipping points, which can lead to future global sea-level rise, researchers have found.
Pine Island Glacier is losing more ice than any other glacier in Antarctica and has been a cause of concern. Along with neighbouring Thwaites glacier, the region is responsible for about 10 per cent of the ongoing increase in global sea level.

Researchers have confirmed for the first time that Pine Island Glacier in West Antarctica could cross tipping points, leading to a rapid and irreversible retreat which would have significant consequences for global sea level.
Pine Island Glacier is a region of fast-flowing ice draining an area of West Antarctica approximately two thirds the size of the UK. The glacier is a particular cause for concern as it is losing more ice than any other glacier in Antarctica.
Currently, Pine Island Glacier together with its neighbouring Thwaites glacier are responsible for about 10% of the ongoing increase in global sea level.
