WHAT WE KNOW
A 110-mile-long rift in an Antarctic ice shelf will break-off and create a massive iceberg larger than Rhode Island.
As to when the part of the Larsen C ice shelf will finally break off is unknown. It would definitely change the landscape of the Antarctic Peninsula.
Experts say it could take days to years. Many suspect it would happen within the next few months because of the overwhelming weight the 110 miles of already separated ice is placing on the 12 miles that remains connected to the shelf. MORE AT USA TODAY
