Antarctica melting: Doomsday Glacier

Glaciologists have described Thwaites Glacier as the “most important” glacier in the world, the “riskiest” glacier, even the “doomsday” glacier. A team of 40 or so scientists are part of the International Thwaites Glacier Collaboration, a five-year, $50m (£38m) joint UK-US effort to understand why it is changing so rapidly.

The project represents the biggest and most complex scientific field programme in Antarctic history. {BBC}
