Edge of Pine Island Glacier’s Ice Shelf Is Ripping Apart, Causing Key Antarctic Glacier to Gain Speed
![Pine Island Glacier ends in an ice shelf that floats in the Amundsen Sea. These crevasses are near the grounding line, where the glacier makes contact with the Antarctic continent. The photo was taken in January 2010 from the east side of the glacier, looking westward. This ice shelf lost one-fifth of its area from 2017 to 2020, causing the inland glacier to speed up by 12%.Ian Joughin/University of Washington Edge of Pine Island Glacier’s Ice Shelf Is Ripping Apart, Causing Key Antarctic Glacier to Gain Speed](https://alaska-native-news.com/wp-content/uploads/image2021-06-18-701x453.jpg)
The ice shelf on Antarctica’s Pine Island Glacier lost about one-fifth of its area from 2017 to 2020, mostly in three dramatic breaks. The timelapse video incorporates satellite images from January 2015 to March 2020. For most of the first two years, the satellite took high-resolution images every 12 days; then for more than […]
