The Doomsday Glacier

There is a massive glacier in Antarctica that’s roughly the size of Florida. It’s one of the Earth’s largest, and there have been predictions that warming temperatures might cause a catastrophic collapse, sheering off huge chunks of ice into the water and causing sea levels to rise nearly three feet. Just imagine how much of the world would suddenly be underwater if that happened. That’s why this particular Antarctic ice sheet is sometimes called the Doomsday Glacier. Some analysis out of the University of Michigan offers hopeful scenarios that suggest the glacier is not approaching complete collapse. Jeremy Basis is a geophysicist at the University of Michigan.
