World’s Largest Iceberg Broke Free and Drifted Toward the Atlantic

Did you know the biggest iceberg in the world is cruising through the ocean right now? It’s called A23a, and it first broke off the Filchner Ice Shelf way back in 1986! For decades, it was just chilling (literally) in the Weddell Sea, stuck on the seabed. Then it started moving again in 2020, only to get trapped in this oceanic vortex called the Taylor Column. But in December 2024, it finally broke free and is now heading toward South Georgia Island. Oh, and get this — it’s over 4,300 square kilometers in size, which makes it more than three times bigger than New York City! Learn more about your ad choices. Visit megaphone.fm/adchoices
