Story summary
- The Pine Island Glacier in West Antarctica now flows about 5 km per year, up 20% since 2017.
- This acceleration follows the disintegration of the ice shelf that previously supported the glacier.
- Researchers from the University of Chicago report the grounding line has retreated by more than 30 kilometers as warmer ocean water undermined the ice shelf.
- This ongoing instability threatens future global sea level rise.
