Four dozen Antarctic ice shelves have shrunk by at least 30% since 1997 and 28 of those have lost more than half of their ice in that time, reports a new study that surveyed these crucial "gatekeepers'' between the frozen ...

A team of environmental scientists from France, Tasmania, Canada, the U.S. and Australia has found evidence suggesting that emperor penguins may be more adaptable to a changing climate than previously thought. In their study, ...
Following the calving of the A-81 iceberg at the end of January 2023, the Brunt Ice Shelf is moving faster than before. It is currently moving approximately 4 meters a day towards the sea, whereas before the calving it moved ...
