In the coming years, we'll need millions of batteries: batteries to store renewable electricity and power a massive fleet of electric vehicles. But those batteries will require certain metals, and those metals have to be mined. And the mining industry can be a mess, sometimes associated with deforestation, child labor, and deadly floods of toxic waste. Is there a better way? Today we journey to the bottom of the ocean to find out. Along the way, we discover a massive government conspiracy and me...

Today we’re sharing an episode of The Carbon Copy, a climate change podcast produced by Canary Media. The topic is extremely timely: heat waves.

In recent years more and more people from Central America have tried to emigrate north to Canada, Mexico, and the United States. Many leave home not because they want to, but because they have to: Droughts, brought on by climate change, have forced many to choose between staying home – and risking starvation – or migrating. But a different way of farming could change that calculus. We look at how climate change is driving immigration, and how climate smart agriculture could help families stay on...

Today we’re sharing an episode of Catalyst, a podcast hosted by Shayle Kann and produced by Canary Media. The topic is a controversial one: solar geoengineering — the idea that we can quickly cool the planet by blocking a small amount of sunlight from reaching Earth. Doing so could have uncertain ripple effects throughout the world’s ecosystems, so very few climate scientists advocate solar geoengineering. Still, learning about these ideas reminds us, for better or worse, how much power we human...

Work. School. The grocery store. We all need to get somewhere. But how we get there has huge implications for the climate. In the United States, transportation - mainly from cars - makes up roughly a quarter of greenhouse gas emissions. It's true, Electric vehicles help reduce emissions. But experts say that to truly give the climate (and humanity) a chance, we need fewer people reliant on cars of any kind. And that means using alternatives like mass transit, walking, and bicycles. But for a lon...

Well, wow. Congress is on the verge of passing the most ambitious climate legislation in U.S. history! Don’t be fooled by its name: the Inflation Reduction Act is a massive investment in clean energy and climate initiatives, aimed at boosting the transition to a low-carbon economy. It also includes some profound compromises. So we called up the smartest climate experts and activists we know to break down this plan – what’s good, what’s not and what’s next? Guests: Dr. Leah Stokes, Professor of E...

A listener called in with a dilemma: What's the most climate-friendly thing she can do with her family farm? Her family owns 126 acres of land in the Willamette Valley in Oregon, which she’s going to inherit one day. And she wondered…should I put up solar panels? Try climate-smart ag? Plant trees? So we flew out to investigate, and found people doing some amazing work – from a regenerative bee ranch to reforesting 400 acres of farmland.

More than a million soccer fans will travel to Qatar this fall for one of the biggest sporting events on Earth: The FIFA World Cup. The event sounds like it will be a climate nightmare, thanks to all the flights, air conditioned outdoor fields, docked cruise ships and brand new stadiums. But despite all this – the organizers claim this month-long event will be carbon neutral. How can they say that? Thanks to carbon offset credits. On this episode we dive deep into the murky world of carbon offse...

Storage! ...Exciting, right? Ok, we’ll prove it to you. Each day, more and more of our electricity comes from intermittent renewables like wind and solar. To balance out our electric grid in the future, we’ll need new ways of storing extra energy, so we can still turn on our lights when the wind isn’t blowing and the sun isn’t shining. This week, with help from Dr. Leah Stokes and Shayle Kann, we explore the wild world of energy storage, from a hidden underground lair to a piping hot thermos ful...

The podcast is about what farmers are doing – or could be doing – to take on climate change. In this episode, we’ll hear about the crops farmers actually grow. And we’ll explore the question, Can that change? Because as the world gets hotter and the weather more extreme, we’ll have to reimagine what we sow and harvest — and also what we eat.

In our episode Fast Fashion’s Dirty Little Secret (Hint: It’s Oil) , we made the call to action: buy less clothing, and keep your clothing for longer. Some of you may have heard that and thought – “ yeah, sure .” It sounds great, but it’s really hard to do, given the ecosystem of desire creation that is social media. How can you buy less when your feed is encouraging you to buy more, more, more? To find out, we talk to beauty influencer Hannah Louise Poston about how social media sucked her into...

Electronics — smartphones, computers, televisions — exact a hefty toll on the planet. One way to lighten their load? Use them for longer. And yet, for decades now, manufacturers have made replacing our gadgets easier than repairing them. But Kyle Wiens, co-founder of the repair website iFixit, has been working to reverse that. He talks to us about why repair matters, why our devices are so hard to repair, and the policies that could change that. Calls to Action Read up on the " Freedom to Repair...

A quarter of global greenhouse gas emissions come from agriculture and land use – and a big portion of those emissions come from producing meat. Adopting a plant-based diet is one of the biggest steps an individual can take to reduce their own carbon footprint. So, should we all stop eating meat? Or is it more complicated than that? This week, we take a tour through the bodily functions of cows, millions of acres of corn, and the hidden policy that shapes the American food system to answer that ...

What can you do if someone you know – or an entire town – isn’t on board with renewable energy? This was the dilemma facing The West Kootenay Eco Society in Trail, a small city in British Columbia. The Eco Society wanted to gain support for an energy pledge, but couldn’t gain traction within the community. Until the Eco Society’s Executive Director got the idea (from a podcast) to send volunteers door-to-door, to have personal conversations about climate solutions. To date, they’ve had over a th...

Militaries around the world emit a lot of carbon, but they aren’t required to report these emissions directly…plus they aren’t exactly known for prioritizing climate change in their projections. Still, if we want to lower emissions and limit global warming, we’re going to need their help. So how exactly do you get an institution whose focus is national protection, to care about climate protection? This week we spoke with retired general Richard Nugee about when he first realized the dangers of c...

Seaweed and giant kelp are sometimes called “the sequoias of the sea.” Yet at a time when so many people are talking about climate solutions and reforestation — there aren’t nearly enough people talking about how the ocean can be part of that. In part one of our two-part series, we go out on the water to see how seaweed can play a role in addressing climate change, and how a fisherman named Bren Smith became kelp’s unlikely evangelist.

To avoid the worst impacts of climate change, we need to stop digging up fossil fuels. But the switch to renewables doesn’t mean we stop digging altogether. Wind turbines contain literal tons of copper and iron. Batteries for electric vehicles contain lithium, cobalt and nickel. All those materials come out of the ground—and we need to dig up more of them to power the switch to renewables. In other words, we need more mining. But mines can wreak havoc on the environment and on communities living...
