A massive crack in one of Antarctica’s largest ice shelves has grown exponentially in recent months, and scientists worry a break-off could destabilize the entire structure.

For two years, United Kingdom-based Project MIDAS has been monitoring a large rift in the Larsen C ice shelf, located on the northern end of the Antarctic peninsula. And if the project’s latest findings are any indication, Larsen C could be headed for a similar fate as nearby Larsen A and Larsen B, which collapsed and disintegrated in 1995 and 2002, respectively.
