"Stunning Footage Reveals Caves and Arches in World's Largest Iceberg"

New footage and photos reveal the erosion of the world's largest iceberg, A23a, as it drifts away from Antarctica, forming caves and arches due to waves and warmer waters. The colossal iceberg, four times the size of Greater London, is gradually being eroded and is now traveling north at a rate of about 30 miles per day. The iceberg, which had been grounded for 30 years, is now likely to be swept along into 'iceberg alley' and could potentially disrupt the feeding routines of wildlife. Additionally, a glacier in the Western Antarctic, called the Cadman Glacier, is losing mass at an alarming level due to climate change, releasing 2.16 billion tonnes of ice into the ocean every year.
