A recent satellite analysis has revealed a concerning trend in Antarctica, with approximately 5,000 square miles (12,950 square kilometers) of grounded ice lost over the past three decades. Conducted by scientists at the University of California, Irvine, the study highlights the significant impact of warming ocean waters eroding the continent's edges, particularly affecting the grounding line, which marks the boundary where ice transitions from resting on bedrock to floating on the ocean. The research utilized radar satellite observations from various international space agencies between 1992 and 2025 to map changes in grounding lines across Antarctica.
