Threshold

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.

Listening to Threshold is free, but creating it is not.

We have always been committed to making the best show we can—and making it available for free.

But that's not possible without financial support.

We’re a 501c3 nonprofit organization, and our work is funded entirely by gifts and grants. When you make a donation to Threshold, you’re directly supporting our independent nonprofit journalism...

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...

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.

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...

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?

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...

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...

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.

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.
