Kieran Mulvaney on the battle for power at the top of the world

How does it feel to stay in a cabin in Alaska? How does one keep their wits about oneself in places like the Arctic when the sun doesn't rise for 65-70 days during polar nights? And before you know it, daylight is back for 24 hours. Kieran Mulvaney has traveled to these lands for over 25 years. His latest book, "Arctic Passages: Ice, Exploration, and the Battle for Power at the Top of the World" is a personal account flush with rich reporting from frigid climes. In this podcast he talks about his experiences of visiting these remote lands, some of the crucial geopolitical implications of melting ice, why global warming is real and how the glacial pace at which we are responding isn't doing us any favours. The Economist has named Kieran's book as among the best non-fiction reads of 2025.
