Summary

Story summary

A new study shows significant ice retreat along Antarctica's grounding lines from 1992 to 2025, with over 40 kilometers lost in vulnerable areas, especially West Antarctica.
About 77% of the coastline remained stable, but warming seas could drive future ice loss.
Researchers retrieved a 23-million-year sediment record indicating human-caused warming could cause irreversible melting.
The scenario indicates sea levels could rise five feet this century, underscoring satellite monitoring.

History

Historical Context

The 1992 signing of the United Nations Framework Convention on Climate Change marked a significant step in addressing global warming, which has since been linked to a 0.6°C rise in temperatures due to human activities. The Intergovernmental Panel on Climate Change warns that continued ice loss from Antarctica could raise sea levels by up to five feet this century, threatening coastal cities worldwide.
