Icy moves

David Vaughan and Chris Doake, glaciologists with the Bristish Antarctic Survey have published a paper which states that atmospheric warming has caused the disintegration of five ice shelves in the Antarctic peninsula, over the last 60 years. The breaking down of the shelves has taken place in the warmest part of Antarctica where the temperature has gone up by 2.5C in the past 50 years. As a result, the shelves have weakened and the amount of summer melting has increased. The loss of a 8,000 sq km stretch of ice has resulted in a change in the map of Antarctica, separating several islands from the continent and giving birth to thousands of icebergs.
