A slab of ice the size of Manhattan, calved from Greenland's retreating glaciers, drifted across Arctic waters and struck Joe Island in September 2026—remaining intact despite the force of impact. The event is less a curiosity than a signal: Greenland's ice sheet is shedding mass at an accelerating pace, and the consequences are no longer abstract projections but physical objects moving through the world. What was once a rare spectacle is becoming a recurring feature of a warming Arctic, each iceberg a fragment of a larger story about what the Earth is releasing.
