claim: The acceleration is making some scientists fear that Antarctica’s ice sheet may have entered the early stages of an unstoppable disintegration.
evidence: Scientists have found that the flow of these ice streams has accelerated in recent years, and suggested that if they were to melt, global sea levels would rise by 1 to 2 m ( 3 ft 3 in to 6 ft 7 in ), destabilising the entire West Antarctic Ice Sheet and perhaps sections of the East Antarctic Ice Sheet.
