Antarctic Megaberg Turns Blue, Signals Rapid Collapse
TL;DR Summary
Satellite imagery shows the megaberg A-23A, once a stable Antarctic giant, turning blue as meltwater ponds proliferate on its surface and edge melting accelerates. By January 2026 its area has shrunk to about 1,182 sq km as warmer waters and sunlight drive rapid disintegration, with scientists cautioning it may not survive the austral summer and highlighting potential implications for ocean circulation and marine ecosystems.
