The climate crisis is affecting glaciers across the world in myriad ways. Dramatic melting, steep declines, and overall reduction in mass are some of the changes seen in both polar glaciers and the mountainous peaks of every continent. Understanding these changes requires understanding how we monitor these enormous ice masses. The health of glaciers affects the well-being of the populations living near them, but they have far-reaching consequences, such as global sea level rise.

Host Dr Alfredo Carpineti spoke with Dr Peter Davis from the British Antarctic Survey about Thwaites Glacier in Antarctica, otherwise known as the "Doomsday Glacier". Thwaites is Antarctica's most endangered glacier and studying it is of global importance.
