There’s a giant crack in an Antarctic ice shelf. Should we be worried?

We asked Northeastern’s Daniel Douglass, lecturer in the Department of Marine and Environmental Sciences and an expert in glacial geography, to explain why ice shelves form, what causes them to crack, and how they affect the environment.
Scientists with Project Midas, the British research team that has been monitoring the rift since 2014, warn that a giant iceberg measuring up to 2,000 square miles—approximately the size of Delaware—may soon break away, or “calve,” from the shelf. “[T]his event will fundamentally change the landscape of the Antarctic Peninsula,” wrote the Project Midas team.
