World's largest iceberg, A23a, is drifting towards the British island of South Georgia. A23a has been monitored for 30 years, since it first calved from Filchner ice shelf in Antarctica.

The colossal iceberg A23a, towering at 40 meters and spanning an area greater than the Australian Capital Territory, is now advancing towards South Georgia Island, a remote British territory near Antarctica.

The world’s largest iceberg, A23a, is drifting northward from Antarctica, potentially threatening South Georgia, a British Overseas Territory in the South Atlantic. The massive iceberg, spanning 3,672 square kilometres (1,418 square miles), has raised fears of ecological disruption and risks to shipping routes.

The trillion-ton slab of ice named A23a could slam into South Georgia Island and get stuck or be guided around it by currents.

Millions of seals and penguins are threatened by a very large iceberg drifting toward their remote island in the South Atlantic. The giant iceberg, named A23a, is the world's largest iceberg ever to break loose from Antarctica.
