Antarctic Glacier's 'Irreversible' Melting Threatens 'Considerable Increase' to Sea Level Rise
New study on Pine Island Glacier shows 'striking vision of the near future,' says co-author
- Andrea Germanos, staff writer
An Antarctic glacier is melting "irreversibly," offering "a striking vision of the near future," a new study shows.
The study published Sunday in the journal Nature Climate Change looked at Pine Island Glacier, the largest single contributor to sea-level rise in the Antarctic.
The team of scientists used three ice flow models to look at the glacier's grounding line, which separates the grounded ice sheet from the floating ice shelf.
The grounding line, which has already retreated by about 10 kilometers in the last decade, "is probably engaged in an unstable 40 kilometer retreat," the study finds.
