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.
