World's largest iceberg A23a drifts towards South Georgia Island

The world's largest iceberg, A23a, is drifting towards South Georgia Island after being grounded for 37 years. It broke off from Antarctica's Filchner Ice Shelf in 1986 and is currently moving northeast at about half a mile per hour. A23a could reach South Georgia in two to four weeks. If it grounds near the island, it may disrupt feeding routes for local wildlife, including penguins and seals. The iceberg's future path remains uncertain, as it may break up or ground. While shipping operators can avoid the large iceberg, smaller pieces that may break off could pose navigational hazards. The area is known as "Iceberg Alley," where icebergs frequently drift.
