Massive iceberg breaks from Eastern Antarctica

The video discusses the calving of iceberg D28 from the Amory Ice Shelf in Eastern Antarctica. The iceberg, larger than Greater London, was first observed in the early 2000s. Scientists note that the calving is part of a natural cycle and not due to atmospheric warming, which affects only Western Antarctica. The calving does not impact sea levels directly but may influence melting under the remaining ice shelf. Maritime authorities are tracking the iceberg for potential shipping hazards.
