Iceberg A-76 is approximately 70 times the size of Manhattan and larger than the Spanish island of Majorca. It recently split from the Ronne ice shelf in the Weddell Sea. It's currently the largest iceberg in the world, measuring approx 105 miles in length and 15.5 miles in width. The iceberg's separation is part of the natural cycle of the ice shelf, as that area hasn't been affected by warming waters like other parts of Antarctica. Scientists don't expect A-76 to affect global sea level rise b
