World’s Former Largest Iceberg A23a Disintegrates After Losing 99% of Its Mass

The Antarctic iceberg A23a, once considered the largest in the world, has lost 99% of its original area and is now "coming to the end of its story,” according to the press service of the Arctic and Antarctic Research Institute. The Rapid Collapse of Iceberg A23a Scientists report that A23a now covers less than 50 square kilometers. As recently as January, its area measured around 1,300 square kilometers, highlighting a dramatic and accelerating decline. Researchers say the iceberg continues to drift while visibly breaking apart into smaller fragments. This rapid disintegration reflects the combined impact of ocean currents, rising temperatures, and structural weakening within the ice mass.
