![]() According to the BAS in the same statement, there is "no evidence that climate change has played a significant role" in this specific event. The giant iceberg thats been drifting through the South Atlantic looks to have experienced a major break-up. A giant slab of ice recently sheared off from Antarctica, and scientists are calling it the largest iceberg in the world. The Brunt Ice Shelf, which typically flows west at about 1.2 miles (2 kilometers) per year, routinely experiences calving events. Concerns were that the berg would run aground in the shallow waters offshore. Three and a half years later, the main part of iceberg, A-68A, drifted worryingly close to South Georgia. The team working at the BAS Halley Research Station say that the station is unlikely to be affected by the recent calving event, according to the same BAS statement. In July 2017, a giant iceberg, named A-68, snapped off Antarctica’s Larsen-C ice shelf and began an epic journey across the Southern Ocean. Ice calving, or iceberg or glacier calving, occurs when large pieces of ice break off of a glacier. One of the planets most closely observed ice shelves just had a major change. These scientists have been expecting a large "calving event" for at least a decade, according to the BAS. Giant iceberg breaks away from the Brunt Ice Shelf in Antarctica 00:59.
