Onboard an expedition to study a massive, melting glacier
Some call it the ‘Doomsday Glacier,’ a vast expanse of Antarctic ice roughly the size of Florida. As temperatures rise, the Thwaites Glacier is melting fast and threatens to raise global sea levels. That’s why a team of nearly 40 researchers is embarking on a two-month journey to study it. Science correspondent Miles O’Brien is with the expedition and reports.
