A crack in the Antarctic ice shelf, now more than 100 miles long and two miles wide, may soon break off, creating one of the largest icebergs ever recorded. And it is growing quickly, increasing 17 miles in the last two months, and the length of five football fields a day.
Since the ice is already floating, its separation won’t raise sea levels. But the glaciers behind it will then melt more quickly, and that will add to a rise in global sea level. And because of warming temperatures, other large amounts of ice in West Antarctica could be vulnerable as well.
Here’s a great story about the ice shelf, with great graphics, from The New York Times:
