Manhattan-Sized Ice Island Breaks Free from Greenland's Petermann Glacier

A massive section of Greenland's Petermann Glacier, approximately the size of Manhattan (76 square kilometers), calved off on August 4, 2026. This event, the largest loss of floating ice from Petermann Glacier since 2012, was observed by Europe's Copernicus Sentinel-1 mission. Scientists will track the rare Arctic iceberg as it drifts, breaks apart, and potentially impacts shipping routes.
