If the steel industry were a country, it would be the world's third-largest emitter. So to prevent a climate catastrophe, this industry has to change. And not just a little bit: we have to fundamentally transform how we make one of the most versatile, durable, widely used materials human beings have ever created. That's exactly what a group of companies in northern Sweden is aiming to do. This is Threshold Season 4: “Time to 1.5” In this episode we travel to northern Sweden to explore how a gree...

For centuries, we have been willing to sacrifice places, ecosystems, and entire species for industries like steel. While steel is one of the most useful materials humans have ever created, it’s also one of the most damaging to the climate and to the people who work in and live near these mills. These conditions help explain why the workers in the steel mills of Gary in the first half of the 20th century came from two main groups: newly arrived immigrants and African Americans who had moved up fr...

Steel is the signature material of the Industrial Revolution. It’s also an essential component of the wind turbines, electric cars, and climate-friendly buildings we’ll need in a decarbonized world. But making steel requires mountains of coal. So we both really need steel and really need to stop making it the way we’re doing now. This is Threshold Season 4: “Time to 1.5.” In this episode, we explore the costs and benefits of our industrial processes on people, communities, and the climate throug...

One of the most challenging aspects of the climate crisis is that we have to do everything at once - transition the entire global economy away from fossil fuels AND deal with the warming that’s already happening. In climate-speak, these two things are called mitigation and adaptation, and one of the places where you can see this playing out is Lagos, the largest city in Nigeria and one of the most important ports in Africa. It’s a city that’s flourishing and also one that is facing a huge proble...

A lot of the changes needed to keep global heating below 1.5 degrees have to occur at a huge, international level. But nearly a fifth of carbon emissions in the U.S. come from our homes. Are there things we can do at home to help the climate crisis? And just how effective are individual actions? This is Threshold Season 4: “Time to 1.5.” In this episode, we zoom in to look at what individuals can do to decarbonize their homes, from small town Livingston, Montana, to New York City. This work depe...

We keep hearing (and saying) that solving climate change is really hard. But we actually know what we need to do - and have the technology to do it - right now. It’s more a question of what happens if we don’t act fast enough. This is Threshold Season 4: “Time to 1.5.” In this episode, we look at some models for how we can realistically meet the 1.5C goal and get to net zero by 2050. There is hope and there are also challenges, but the biggest barriers and our most promising tools are our imperf...

The number of things at stake in the climate crisis do not fit inside one episode. It's hard to even fit them inside your mind. Part of what makes the potential losses so hard to grasp is that they're happening at lots of different scales, all at the same time. And as we move back and forth between what's happening out our own backdoors with what we know is happening all around the globe, one thing becomes very clear: there's no separating what we're doing to nature from what we're doing to ours...

Britain was the first place in the world to go through what we now call the Industrial Revolution, a transformation of an agricultural, rural society into a manufacturing powerhouse that kicked off the mass migration of ancient carbon from the ground to the atmosphere. This is Threshold Season 4: “Time to 1.5.” In this episode, we explore the mass acceleration of nearly every process on earth that began in Britain in the 1700s and continues to this day, a multi-century fossil-fuel binge that kno...

There are quite a few things working against us when it comes to understanding how urgently we need to act on climate change. But there's also the simple fact that we can't literally see how we're changing the atmosphere. It’s time to give the atmosphere its due. This is Threshold Season 4: “Time to 1.5.” In this episode, we go straight up, into our atmosphere. This work depends on people who believe in it and choose to support it. People like you.

After decades of scientific study and political wrangling the world has agreed—at least on paper—that 1.5C of heating must be the upper limit of our impact on the climate system. How could something that sounds so small matter so much? This is Threshold Season 4: “Time to 1.5.” In this episode, we take you inside the scientific and political origin story of 1.5C, from the holocene to the halls of COP26 in Glasgow.

Humanity has a mission right now: to keep global heating to no more than 1.5 degrees Celsius over pre-industrial levels. Science tells us that we have less than a decade to do it, and that if we don't, the consequences will be dire. That's humanity's mission, and that's what season 4 of Threshold is about. It’s called “Time to 1.5.” In this season, we’re going to grapple with what it means to be living through this pivotal moment, when what we do and don't do will have impacts that ricochet out ...

For the last few months now, we’ve been telling you that we’re working on season four of Threshold. But we haven't told you what it's about. We're going to fix that now...sort of. We're going to tell you a story of something Amy did several years ago—something that very nearly had disastrous consequences—which is kind of a metaphor for what season four is all about. Consider this a strong hint about what's to come in just a few weeks. In-depth reporting on climate change, environmental justice, ...

We’re inviting you to join us in a new experiment we’re calling the Audio Mosaic Project. The sound of place has always been an important part of our show — think the chirps of crickets, the flow of water, the crunch of boots on snow. Using the noises we take for granted in the backgrounds of our lives, we bring listeners right there with us, to the places we report. For over a year now, we haven’t been able to travel and get out into the world to collect sound. So as we work on season four of o...

After four decades of fighting, the lease sale for drilling rights in the Arctic National Wildlife Refuge was held on January 6, 2021. Amy sat down with David Aaronovitch of The Times of London to talk about what happened at the lease sale for their podcast, “Stories of our Times.” Amy and David talk about what the outcome means for the future of the refuge, and also revisit some of the central questions of season three of Threshold: Why drill in the refuge?

Last week, the National Bison Range in northwest Montana was returned to the people of Confederated Salish and Kootenai Tribes. As part of the COVID relief bill signed into law at the end of December, the lands of the bison range were returned to the Flathead Reservation. There will be a two-year transition period as the management duties are passed off from the US Fish and Wildlife Service, and after that, the CSKT will be the exclusive manager of the National Bison Range and this herd. To make...

The controversy over oil drilling in the Arctic National Wildlife Refuge is at a critical point: a lease sale may be just days away, but lawsuits have piled up that could put a stop to that sale and put a wrench in the federal government’s efforts to open the refuge to drilling. In this update to our Peabody Award-winning series The Refuge, we dive into this moment through conversations with three lawyers and Vebjørn Aishana Reitan, a polar bear guide in Kaktovik, the only village within the ref...

The Greenland ice sheet is the second largest body of frozen water in the world, with the potential to raise sea levels by 23 feet if it melts. In this Threshold extra, we’re talking with leading climate scientists and glaciologists about the cryosphere—all the things that are frozen in the Earth’s system: permafrost, sea ice, land ice, and snow. We take a close look at how two of its key elements have fared in 2020: the Greenland ice sheet and Arctic sea ice. Each of these components of the cry...
