Greenland’s Massive Iceberg Breaks Free | Science News

A massive 76-square-kilometer iceberg—larger than Manhattan—calved off Greenland’s Petermann Glacier on August 4, 2026, captured in stunning detail by the Sentinel-1 satellite. This event, the largest Arctic calving since 2020 and the biggest at Petermann since 2012, marks a dramatic acceleration in polar change. Scientists, who’ve been monitoring fractures since 2019, now have unprecedented radar data showing how the ice cracked and broke in near real-time. While Petermann has calved before, this latest break signals a return to instability after years of calm. The iceberg poses new risks for Arctic shipping and offers a rare window into how glaciers reshape sea levels—and our planet’s future.
