If warming exceeds 2°C, Antarctica’s melting ice sheets could raise seas 20 metres in coming centuries

New research shows that warming by more than 2°C could be a tipping point for Antarctica’s ice sheets, resulting in widespread meltdown and changes to the world’s shorelines for centuries to come.
