Antarctic ‘glue’ coming unstuck could be crucial in causing deterioration of ice shelves

The video discusses a study on the Larsen Sea Ice Shelf, highlighting the role of ice melange in stabilizing ice shelves. Thinning of the melange, rather than the ice shelf itself, can lead to increased rift widening and iceberg calving, as seen with the A68 iceberg. This challenges previous beliefs that hydrofracturing was the primary cause of such events. The study suggests that ice shelves may become unstable and retreat sooner than expected, impacting sea level rise predictions.
