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 (拢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.

The 成人论坛's chief environment correspondent Justin Rowlatt went to meet the scientists behind the project.
