On the edge of the ice

Thwaites Glacier in Antarctica is massive, bigger than the state of Florida. If it collapses, it could reshape every coast on this planet during this century. That’s why it’s sometimes known as “the Doomsday Glacier.” And yet, until recently, we knew very little about it. Because Thwaites is extremely remote, reachable only by crossing the wildest ocean on the planet, scientists had never observed its calving edge firsthand. In 2019, a ground-breaking international mission set out to change that, and writer Elizabeth Rush was on board to document the voyage. We caught up with her to learn about life on an Antarctic icebreaker, how she grappled with classic Antarctic narratives about exploration (and domination), and how she summons hope even after coming face-to-face with Thwaites. This episode was first published in early 2024. Featuring Elizabeth Rush. SUPPORT Outside/In is made possible with listener support. Click here to become a sustaining member.

A paper published in Nature with some of the findings from Elizabeth's voyage, showing that Thwaites has historically retreated two to three times faster than we’ve ever observed. Here’s the one detailing findings about Thwaites’ past extent, extrapolated from their study of ancient penguin bones, and another sharing observations about water currents beneath its ice shelf. The Trump administration has pulled funding for the US’s only Antarctic icebreaker dedicated to scientific research. Read about the fate of the RV Nathaniel B. Palmer in Scientific American.
