Antarctic glacier's rapid retreat sparks scientific 'whodunnit'

A recent study unravels the mystery behind the rapid retreat of the Hektoria Glacier in Antarctica, suggesting it might be due to a process where the glacier's front resting on the seabed destabilizes. This finding could have significant implications for sea-level rise if it occurs in other parts of Antarctica. However, some scientists are skeptical due to uncertainties about the glacier's grounding line. The study highlights the urgent need for further research to monitor and understand the impacts of rapid changes in Antarctica on global sea levels.
