In August 2026, a glacier on Greenland's northwest coast released a slab of ice larger than a small island — the Arctic's most significant calving event in six years — and the berg survived a collision that many expected would destroy it. The event reminds us that ice, like history, does not always break where we anticipate. Scientists watch these departures not merely as spectacle, but as slow dispatches from a changing planet, carrying freshwater and hazard southward into waters shared by ships, ecosystems, and the long arithmetic of rising seas.
