A giant iceberg the size of Greater London broke off from Antarctica’s Brunt Ice Shelf in 2023 — and now, scientists believe tides may be the surprising trigger. New research reveals how spring tides, high winds, and ice stress combined to cause the dramatic calving of iceberg A81. Glaciologist Oliver Marsh had predicted the event, marking a breakthrough in understanding how and why these massive icebergs break free.
This short video explains what happened, what it means for global sea levels, and why future iceberg breakups may be even more unpredictable. As climate change accelerates the melting of Antarctica’s ice, scientists warn we are entering uncharted territory.
