Video: Consequences of 1,000 billion tons of icebergs separated from Antarctica

1,000 billion tons of icebergs separating from the Larsen C ice shelf in Antarctica can boost the ice crack, causing many other icebergs to fall into the sea.

When ice shelves 'give birth' to icebergs, the ocean will be disturbed.

When ice shelves 'give birth' to icebergs, the ocean will be disturbed, icebergs and its fragments can 'wander' in the ocean for many years.

Ice shelves play a role in preventing glaciers from flowing straight into the sea. Therefore, scientists said that if Antarctic glaciers were controlled by Larsen C ice shelves directly into the ocean, the global sea level would rise about 10cm.
