After breaking off from the Antarctic ice shelf nearly 40 years ago, the iceberg codenamed "A23a" has long ranked first among the world's "giant" icebergs. However, relevant information shows that the iceberg is rapidly disintegrating, and researchers predict that it may not survive until the end of November 2025.

Since the crash of the A23a ice sheet from Antarctica in 1986, the A23a ice sheet has been laying on the seabed for more than 30 years in the Wedel Sea, and then began to move north after 2020 due to melting ice sheet. With the "A23a" disintegration, the ice sheet "D15a" with an area of about 3,000 square kilometers jumped into the world's largest ice sheet.

Previously, researchers predicted that with the arrival of the spring in the southern hemisphere, the sea will continue to warm, "A23a" could quickly break down into several smaller and smaller pieces.
