Dhaka, March 5 -- year study by glaciologists from the University of California, Irvine has produced the first comprehensive map showing how Antarctica's grounding line - the point where land ice meets the ocean - has shifted over time.

Using three decades of satellite data, researchers found that while most of the continent has remained relatively stable, several vulnerable regions are losing large amounts of grounded ice. The total loss between 1996 and 2026 reached about 12,820 square kilometers, an area roughly equal to 10 cities the size of Greater Los Angeles.

The research, published in the Proceedings of the National Academy of Sciences, shows that 77 percent of Antarctica's coastline has experienced no grounding line movement si...
