ESA’s Copernicus Sentinel-1 captured a 29-square-mile (76-square-kilometer) section of Petermann Glacier’s floating ice tongue breaking away on Aug. 4, 2026—the Arctic’s largest ice-calving event since 2012—highlighting ongoing Greenland ice loss linked to warming oceans and climate change. Scientists say such observations help track glacier dynamics and their implications for sea-level rise and polar environments.
