Doomsday Glacier (West Antarctica's Thwaites Glacier)

Doomsday Glacier

The glacier is roughly 80 miles across, the widest on Earth. It packs so much ice that if it were to completely collapse, it could singlehandedly cause global sea levels to rise by more than two feet, according to the International Thwaites Glacier Collaboration, prompting its moniker as the “Doomsday Glacier.”
