World’s Largest Iceberg Breaks Off of Antarctica

An enormous iceberg, a little bigger than the state of Rhode Island, has broken off of Antarctica. Because the ice shelf that this berg calved from was already floating on water, the event won't directly impact sea levels. “It's important to monitor the frequency of all iceberg calving, but these are all expected for now.”Satellites will continue to track the new iceberg, much as they did for A-68A, the previous title holder for the world's largest iceberg. After splitting from the Antarctic ice sheet in 2017, A-68A was set loose by ocean currents in 2020 and came perilously close to colliding with South Georgia Island, a breeding ground for seals and penguins. The Ronne Ice Shelf, which birthed the recent iceberg, is mostly spared from influxes of warm water that disrupt the Antarctic's natural cycle of ice calving and regrowth.
