US EditionForty percent of Antarctica’s ice shelves are shrinking, worrying scientists
- A new study reveals that 68 out of 162 Antarctic ice shelves have experienced significant shrinking since 1997, with four dozen of them losing at least 30% of their ice and 28 losing more than half of their ice.
- Concerns about climate change-triggered melt from Antarctica and Greenland causing dangerous and substantial sea rise arise from the melted ice from these ice shelves, which leads to larger glaciers flowing into the sea.
- The study provides crucial insight into the melting of fresh water into the Amundsen Sea, which contributes to sea level rise and affects the density and salinity of the ocean.

Scientists count huge melts in many protective Antarctic ice shelves, trillions of tons of ice lost
A new study finds that 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. These are the crucial “gatekeepers’’ between the frozen continent’s massive glaciers and the open ocean. Thursday's study finds that of the continent’s 162 ice shelves, 68 of them show significant shrinking trends between 1997 and 2021, while 29 grew, 62 didn’t change and three lost ma…
