World's Largest Iceberg Crumbles! Trillion-Tonne Megaberg Shatters After Years of Stability
The Journey of the World’s Largest Iceberg At the start of this year, the world's largest iceberg, A23a, was more than twice the size of Greater London. As we enter September, scientists are watching with concern as this massive ice structure is nearing its end. Known as one of the oldest and largest megabergs ever recorded, A23a has been breaking apart in warmer waters and may disappear within weeks. Shaped like a tooth, A23a has been drifting north through the South Atlantic Ocean for months. Now exposed to increasingly warmer waters and large waves, the former 'king of the seas' has rapidly disintegrated. According to Mr. Andrew Meijers, a physical oceanographer at the British Antarctic Survey (BAS), A23a has been 'breaking up fairly dramatically' as it moves further north. He described the process as 'rotting underneath,' with the water being too warm for the iceberg to maintain its structure. In early 2024, A23a weighed around one trillion tonnes—abo...
