World's Largest Iceberg A23a Begins Drift After Three Decades

Concerns arise over potential disruption to wildlife and shipping lanes as the iceberg moves towards South Georgia and possibly South Africa.

World's largest iceberg, A23a, has started moving after being grounded for more than 30 years in the Weddell Sea.
The iceberg, which is more than twice the size of Greater London, is currently passing the northern tip of the Antarctic Peninsula.
Scientists speculate that the iceberg has started to move due to a decrease in size, allowing it to lose grip and start moving.
There are concerns that the iceberg could disrupt the feeding grounds of seals, penguins and seabirds if it runs aground at South Georgia, a British Overseas Territory.
If the iceberg continues its trajectory, it could potentially disrupt shipping lanes near South Africa.
