Antarctica's A-23a Iceberg, Twice Mumbai's Size, Nears Disintegration

• Antarctica's A-23a, one of the largest icebergs ever recorded, is rapidly melting in warmer ocean waters.
• Originally 4000 sq km (twice Mumbai's size), it has shrunk to 1182 sq km by early January 2026.
• Satellite images from NASA's Terra and ISS show large blue meltwater ponds on its surface, indicating advanced disintegration.
• Experts attribute the blue color to accumulated meltwater, which accelerates the breakup process by widening cracks.
• Located between South America and South Georgia Island, its complete disintegration is considered inevitable due to warm waters and rising air temperatures.
