  • On the edge of the ice
    Oct 15 2025

    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.

    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 Brick Lady of St. Louis
    Oct 8 2025

    Ever since a tornado tore through one of St. Louis, Missouri’s poorest neighborhoods, there are piles of bricks all over the place.

    It’s not just a debris problem. Bricks in St. Louis have a long and complicated history here – the darling of many historic preservationists and a good source of profit to just as many demolition crews.

    Producer Marina Henke spent a week in North City, tagging along with a brick layer who’s racing against the clock to build back homes. Can North City keep its bricks? Should they even try?

    Featuring Natalie Hughes, RJ Koscielniak, and Rasheen Aldridge.

    Produced by Marina Henke. For full credits and transcript, visit outsideinradio.org.

  • O/I Trivia: Natural Selection
    Oct 1 2025

    What do pastries have to do with environmental justice? Cat butts with the climate crisis? And what US president ate a half-chewed piece of salmon leftover from a bear on reality TV?

    Grab a pencil (and maybe a pint?) and get ready for the inaugural Outside/In trivia episode we’re calling “Natural Selection.” We’ve got a game called “Guess That Animal!” We’re testing our panel’s knowledge on the environment in movies and music. And, maybe, we’ll learn a thing or two along the way about environmental policy, past and present.

  • How to solve the climate crisis in 60-90 minutes
    Sep 24 2025

    When designer Matt Leacock decided to make a board game about climate action, he knew he wanted to make it – first and foremost – fun to play. “If we sold anything as an educational game… people would run screaming and running for the hills,” he told us.

    But can simulating the climate crisis really make for a good Friday night with your friends? What are the limits to gamifying social issues as complex as global warming?

    In this episode, we speak with Matt about what it took to design an entertaining game about one of the most challenging topics of our time, and enlist a few friends to playtest his game: “Daybreak.”

    Featuring Matt Leacock, with appearances from NHPR’s Marina Henke, Nick Capodice and Hannah McCarthy. This episode was produced by Taylor Quimby. For a full list of credits and transcript, visit outsideinradio.org

  • Why is there so much roadkill?
    Sep 17 2025

    For humans, roads epitomize freedom. For wildlife, it’s a different story: a million animals are killed by cars every day in the US alone. How did our infrastructure turn so deadly? And what are people trying to do about it?

    In this episode, we look at how two very different species are impacted by roads. Along the way, we visit a turtle rescue clinic, and hear about a celebrity cougar that was trapped in the Hollywood Hills.

    This episode was first produced in 2023.

    Right now, the Trump administration is planning to rescind the Roadless Rule – a regulation that restricts the building of new roads in nearly 60 million acres of US forests. Conservationists warn that this will fragment forests and threaten endangered species. A public comment period on the plan is open until September 19th.

    Featuring Ben Goldfarb, Alexxia Bell, Natasha Nowick, and Michaela Conder.

  • The cold truth about refrigeration
    Sep 10 2025

    In the early 1900s, people didn’t trust refrigerated food. Fruits and vegetables, cuts of meat… these things are supposed to decay, right? As Nicola Twilley writes, “What kind of unnatural technology could deliver a two-year old chicken carcass that still looked as though it was slaughtered yesterday?”

    But just a few decades later, Americans have done a full one-eighty. Livestock can be slaughtered thousands of miles away, and taste just as good (or better) by the time it hits your plate. Apples can be stored for over a year without any noticeable change. A network called the “cold-chain” criss-crosses the country, and at home our refrigerators are fooling us into thinking we waste less food than we actually do.

    Today, refrigeration has reshaped what we eat, how we cook it, and even warped our very definition of what is and isn’t “fresh.”

    Featuring Nicola Twilley.

  • All Wings Considered
    Sep 3 2025

    We’re catching some air this week, and talking things with wings!

    Quandaries range from the practical (how do different animal and insect wings differ?) to the ethereal (this includes dragons). Here’s the questions we’ll be answering…

    1. What makes wings different?
    2. How have wings in nature inspired human flight?
    3. Did we ever solve the colony collapse problem with bees?
    4. Why do so many cultures have dragon myths?

    Featuring Jonathan Rader, Tim Burbery, Lauren Ponisio, and Andrew Howley.

  • Saving the shipwrecks of Stellwagen Bank
    Aug 27 2025

    Shipwrecks captivate our imagination, and are the subject of many books, academic papers, and movies—from the world-famous Titanic, to sunken World War II warships, to ancient fishing canoes. Some describe them as time capsules of our maritime history, waiting to be discovered and opened.

    But there’s a group of people who are drawn to shipwrecks for very different reasons, and it sometimes leads to the demise of the wrecks themselves: fishermen.

    In this episode, why archaeologists and fishermen have sometimes been at odds over shipwrecks, and the federal government program that’s bringing them together under one common cause.

    Featuring Ben Roberts, Mike Bailey, Tom Hill, Calvin Meyers, and Ben Haskell.
