ESA/Earth Observation An iceberg bigger than Majorca that calved off an Antarctic ice shelf has been spotted by satellites, and declared the world’s largest iceberg. The finger-shaped iceberg, which is about 4320 square kilometres in size, isn’t thought to have been caused by anthropogenic climate change. Advertisement Named A-76, the iceberg broke off the Ronne ice shelf into the Weddell Sea in recent days, according to the European Space Agency. The area has been spared an influx of warm ocean water affecting other parts of western Antarctica, which is threatening to release huge glaciers such as one called Thwaites.
