The world's oldest and largest iceberg will soon be no more
Summary
The world's oldest and largest iceberg, named A23a, is breaking up in the warmer waters of the South Atlantic Ocean after nearly 40 years. The iceberg, which has been closely monitored since it broke off from Antarctica in 1986, is now rapidly disintegrating into large chunks. This process is part of the natural life cycle of icebergs and is not linked to climate change.Key Facts
