The ‘Doomsday Glacier’ Could Flood the Earth. Can a 50-Mile Wall Stop It?
This month, an international team of scientists has been trying to set up sensors on and around Thwaites Glacier, one of the most unstable in the world. It’s often called Antarctica’s “doomsday glacier” because, if it collapses, it would add two feet of sea-level rise to the world’s oceans. On Thwaites itself, part of the team will try today to drop a fiber-optic cable through a 3,200-foot borehole in the ice, near the glacier’s grounding line, where the ocean is eating away at it from below.
