As of Jan. 16, the megaberg, known as A23a, is roughly 180 miles (290 kilometers) away from South Georgia and the South Sandwich Islands, according to location coordinates from the U.S. National Ice Center. A collision with these islands could be catastrophic for the large colonies of penguins, seals, and other wildlife that live there.
The world's largest iceberg is on a collision course with a remote British island, potentially putting penguins and seals in danger. The iceberg is spinning northwards from Antarctica towards South Georgia, a rugged British territory and wildlife haven, where it could ground and smash into pieces. It is currently 173 miles (280km) away.
If it gets stuck near South Georgia Island, that could make it hard for penguin parents to feed their babies and some young could starve.
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 slab of ice — named A23a — weighs almost one trillion tonnes and could slam into South Georgia Island before either getting stuck or being guided around the land by currents.
The A23a iceberg broke away from Antarctica nearly 40 years ago and is now en route to smash into British territory South Georgia - posing a serious threat to penguins and seals
It’s also a natural process happening more frequently because of human-caused climate change, said British Antarctic Survey physical oceanographer Andrew Meijers, who examined the iceberg up close in December 2023 when it drifted past the research ship RRS Sir David Attenborough.
More than twice the size of greater London, the expanse of ice is unpredictable and dangerous.
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.
