  • It is about 210 metres thick and contains 315 billion tonnes of ice.
  • The east of Antarctica — where D28 broke off — is different from the west of the continent and Greenland, which are rapidly warming due to climate change.

Not related to Climate Change

  • Scientists found that the event is part of a normal cycle and is not related to climate change.
  • The figures are huge, but iceberg production is part of the normal cycle of ice shelves, which are an extension of the ice cap.
  • Ice shelves have to lose mass because they gain mass.
  • The gain in mass comes from snow falling on the continent and glaciers that move slowly toward the shore.
