The world's largest iceberg is moving after 30 years
The world's largest iceberg has begun to move after more than 30 years.
Called A23a, the iceberg is close to 4,000 square meters.
Movement was observed last year and now appears to be moving beyond Antarctic waters.
A23a was part of a massive break of a giant ice sheet, the BBC wrote.
Global warming is leading to an irreversible process of melting large amounts of Antarctic ice, and reducing the amount of carbon from the atmosphere is the only solution to slow this process.
Big bergs release mineral dust they incorporated into their ice when they were part of glaciers scraping across Antarctic rock. They fertilize the ocean.
