Threshold

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.

Humans are born into a wondrous planetary chorus. But today, many of us rarely hear anything other than ourselves. In this season of Threshold, we explore a world teeming with sound and ask what happens when we tune into the life all around us. Season 5 of Threshold, Hark, is coming Tuesday, November 19th.

In June 2024, the planet hit a terrifying milestone: 12 straight months of global temperatures at or above 1.5 degrees over pre-industrial levels. But even as the impact of climate change becomes more visible and far-reaching, the opportunity to change the trajectory of this global crisis remains possible. Hope is possible. Today, we’re sharing a conversation with writer and activist Rebecca Solnit, a leading voice on the climate crisis and a dogged champion of possibility and promise.

In Season 1 of Threshold, we reported on the decades-long fight to get the federal government to transfer the National Bison Range, and the bison, back to the Confederated Salish and Kootenai Tribes. In 2020, it finally happened. Stewardship of the herd was returned to the people who had helped to save these animals from extinction more than a century before. It’s one of just a few cases where the U.S. government has actually returned a piece of land to the Native American people it was taken from. Earlier this year, we came back to the Bison Range to find out how things are going for the herd and what the restoration of this land has meant to the Tribes.

Yellowstone National Park recently released a new plan for managing the bison herd. It’s in draft form, and maps out three alternatives for how to manage the herd in the future. Before it gets finalized, the public has a chance to read it and weigh in on which path is best. We talked with Morgan Warthin, chief of public affairs at Yellowstone National Park, to learn what this could mean for the future of the bison.

What questions do you have about bison, bison science, bison history, and bison management? Send your questions to us at [email protected] and we’ll try to answer as many as we can in an upcoming dispatch.

A lyrical ode to our atmosphere: the invisible, underappreciated substance that makes all life on Earth possible. 

There are quite a few things working against us when it comes to acting on climate change—not least of them, the simple fact that we literally can’t see the atmosphere, or how we’re changing it. 

In this episode, we take a guided tour of the Earth’s atmosphere to understand the science, beauty, and wonder of our “magical safety blanket.” Our tour is led by a trio of scientists: astrophysicists Dr. Anjali Tripathi and Dr. Hannah Wakeford, and hydroclimatologist Dr. Francina Dominguez. 

Join us in giving the atmosphere its due.

This episode originally aired on February 8, 2022.

A few weeks ago, the Biden administration approved the Willow project. It’s a plan to extract 600 million barrels of oil from northern Alaska. There’s a lot of history and politics behind this story, things that tie to issues we’ve reported on in past seasons of Threshold. 

Amy Martin wrestles with this project and what it means for our netzero future in this month’s issue of our newsletter.

Representatives from nearly every country in the world are in Egypt right now for COP27, the annual climate conference hosted by the United Nations. The overall goal of each COP is to make progress on climate; to get all countries moving in the same direction, toward a decarbonized world, in an equitable way, based on the best scientific information available. But some are now saying that we should abandon hope of holding global average temperature rise to 1.5 degrees Celsius over pre-industrial temperatures.

But we don't think that. And here's why.

Threshold's year-end fundraiser is underway right now. Donate today to keep Threshold going strong. Our listeners make this work possible.
