Journey to the Doomsday Glacier (2020x4)

Air date: Feb 07, 2020

Glaciologists have described Thwaites Glacier as the "most important" glacier in the world, the "riskiest" glacier, even the "doomsday" glacier. Scientists from the UK and US are studying the glacier's changes as part of the International Thwaites Glacier Collaboration. The BBC's chief environment correspondent Justin Rowlatt visited the project.
