Threshold Podcast

A Peabody Award-winning podcast about our place in the natural world. Listen to our latest season: Hark.

Threshold is a public radio show and podcast that tackles one pressing environmental issue each season. We report the story where it's happening through a range of voices and perspectives. Our goal is to be a home for nuanced journalism about human relationships with the natural world.

All over the world, small groups of complete strangers are getting together to share their feelings about climate. These gatherings are called Climate Cafes, and they’re carving out space for some big emotions we might prefer to avoid.

On this episode of Threshold Conversations, we’re joined by Audrey Martin, a Bay Area psychotherapist and one of the leaders of to unpack some of our complicated, scary emotions around climate, and to make the case for why this kind of self-reflection isn’t just comforting—it’s crucial.

We need more than AI to really understand what dolphins are saying, says Dr. Stephanie King, a Professor of Animal Behaviour at the University of Bristol, U.K., and co-director of Shark Bay Dolphin Research in Australia. After decades of studying dolphins, there’s so much we still don’t know, and she says that there’s still no substitute for quietly watching—and listening.

Our Behind the Scenes episode of Season 5 is out now.

In this special episode, you’ll hear not only from Amy, but also Erika, our managing editor, and Sam, our associate producer and fact-checker extraordinaire. They discuss why we decided to make this season of the show, how listening makes us feel vulnerable, and a surprisingly fun get-to-you question you didn’t know you needed.

We're often awed by the generosity of the Threshold listener community, but you blew us away this year. Our 2024 year-end campaign raised $100,269 from 281 donors, making it one of the most generous giving periods in the history of our show. Thank you so much.

As we head into a new year, we're excited to bring you new episodes of Season 5. Before we do, we're taking a brief pause. During this time, we encourage you to embark on your own journey of listening, whether to the voices of others or the quiet rhythms of the natural world.

Thank you, and happy New Year,
Team Threshold

Threshold, Season 5, Episode 1: “The Slime of Life” is out now.

For most of our planet’s existence, the Earth was quiet. The boisterous sounds of life we know today are a recent development, one that the growing field of bioacoustics is helping us understand and interpret. In this episode, we travel to Australia to listen to dolphins and meet the microbes that helped usher in life on the planet.
