DUBAI, United Arab Emirates — Thousands of miles from the U.N.’s climate summit in the Middle East, the world’s largest iceberg is on the move for the first time in more than 35 years.Scientists believe the juggernaut’s breakaway from Antarctica was a natural occurrence, but say it provides a stark reminder of the potentially disastrous implications as global sea levels rise.
The iceberg, known as A23a, is estimated to cover an expanse of almost 4,000 square kilometers (1,500 square miles), making it roughly three times the size of New York City.
