EventOn Aug. 4 2026 a Manhattan‑sized iceberg—76.4 km²—split from Greenland’s Petermann Glacier, its largest calving since 2020 and biggest floating‑ice loss since 2012. Satellite images show the detachment added fresh water to the Arctic Ocean, while scientists warn that up to two more icebergs could soon break off, posing shipping hazards.
Satellite images captured an ice island roughly the size of Manhattan separating from Petermann Glacier—its biggest floating-ice loss since 2012—highlighting rapid glacial calving that adds fresh water to the Arctic Ocean.
An August calving produced a Manhattan‑sized ice island from Greenland’s Petermann Glacier. Scientists are studying the event to learn about ice dynamics that could inform understanding of polar sea‑ice changes worldwide.
A 76.4‑km², Manhattan‑sized iceberg split from Greenland’s Petermann Glacier on Aug 4, 2026 – the largest Arctic calving event since 2020 – and scientists warn that two more large sections could soon break off, potentially removing roughly 22 % of the glacier’s floating tongue and posing drifting‑ice hazards to Arctic shipping.
A Manhattan‑sized iceberg broke free from a Greenland glacier—its largest calving event since 2012—and experts warn that up to two even larger icebergs may eventually break off.
A 76‑sq‑km ice island broke free from Greenland’s Petermann Glacier on August 4, 2026—its biggest Arctic calving event since 2020—and was tracked in real time by Copernicus’ Sentinel‑1 radar, underscoring rapid polar change and new risks for shipping.
A Manhattan‑sized ice island calved from Greenland’s Petermann Glacier after years of observation, underscoring continuing shifts in Arctic ice conditions.
