Antarctica has lost 10 times the size of Greater Los Angeles in ice over 30 years, satellite data reveal
A 30-year satellite radar study reveals Antarctica lost about 12,800 sq km of grounded ice, with 77% of the coastline stable but rapid retreat in key vulnerable sectors.
- A study found Antarctica lost 12,820 square kilometers of grounded ice over 30 years, equivalent to 10 cities the size of Greater Los Angeles.
- While 77% of Antarctica's coastline experienced no grounding line migration since 1996, concentrated retreat occurred in West Antarctica, the Antarctic Peninsula, and parts of East Antarctica.
- The study provides crucial benchmarks for projecting future sea level rise and offers context for reconciling divergent mass balance assessments in East Antarctica.

Antarctica Has Lost Ice Equal to 10 Los Angeles–Sized Cities in 30 Years
After analyzing three decades of satellite radar data, scientists have created the first continent-wide record of Antarctic grounding line migration. A sweeping 30-year investigation led by glaciologists at the University of California, Irvine has delivered the first continent-wide map showing how Antarctica’s grounding line has shifted over time. By examining three decades of satellite observations, [...]
New 30-year Antarctic study reveals massive ice loss, uncovered by commercial satellite radar
/PRNewswire/ -- Nearly a quarter of Antarctica's coast-reaching glaciers are in retreat, shedding the equivalent of one Greater Los Angeles every three years,...
Antarctica lost 12,800 kilometres of coastline in just three decades in the critical zone that separates the land-based ice from that that floats over the sea. The retreat has not been uniform, but where it has occurred, the response has been swift and forceful. An international team led by the University of California has prepared the most complete map to date on the migration of the Antarctic support line between 1992 and 2025, confirming that…
