What On Earth

Pope Francis established himself as a leading voice on climate action, but it’s not yet clear how that legacy will be preserved once a new pope is in place. Katharine Hayhoe, Global Chief Scientist of Nature United and Distinguished Professor at Texas Tech, weighs in on Pope Francis’s legacy. Then, we talk to Molly Burhans, cartographer and founder of GoodLands, who is mapping the vast swathes of Catholic Church-owned land around the world to help protect the climate. 

In remote northern communities, diesel is king. But breakthrough solar energy projects are underway that could begin to reduce fossil fuel reliance. This year, the theme of Earth Day is renewable energy, so we’re taking you to Nunavut where people are adding solar panels to small off-grid cabins and others are working on community-scale solar projects — so the diesel generators can finally be turned off and communities can hear silence once again, like their ancestors did.

Climate hasn’t been a hot topic on the campaign trail, but did it come up in the debates? We hear about that from CBC’s Aaron Wherry. Then, we talk climate policy with NDP candidate Samantha Green. And, we hear what the Conservatives have been saying about climate and energy in this election.

The Green Party aims to be the environmental conscience of parliament. But its popularity has waned as people consider strategic voting in the face of other concerns – and as climate change slips as a priority for voters. We speak to Green Party advisor Daniel Green about how the party is balancing its climate policy with other issues in this election and whether co-leaders Jonathan Pedneault and Elizabeth May can overcome their low poll numbers. We also hear from voters on whether climate is a ballot box priority.

The parties aren’t talking climate much on the campaign trail. But we are - we’ve got tough questions for all of them. First up, Jonathan Wilkinson of the Liberal party. We also talk to voters about why the warming planet isn’t a top priority for them this time.

Japan’s burgeoning wind energy sector is turning to robots to keep the industry moving. They can do work that is trickier and riskier for their human counterparts. CBC’s Cathy Senay takes us on a journey across Japan to find out how.

Students at some of Canada’s top universities are demanding banks stop funding fossil fuel projects and are calling on their schools to cut ties with major financial institutions. What On Earth’s youth climate action columnist Aishwarya Puttur explains the lengths that students are going to – from confronting bank executives to picking up protest signs – to support the cause, racking up some wins in their campaign along the way.

Climate-friendly menstrual products come with a lot of complex considerations, like personal preferences, stigma and cost. We visit a start-up in Nova Scotia that’s making compostable pads. Then – we hear about the policy and social changes that could help make sustainable options more accessible.

How do you include more voices in the climate change conversation? In a diverse country like Canada, there’s a growing need to have a wider variety of languages in the discussion. Climate justice columnist Chúk Odenigbo takes us through the concept of linguistic justice and why it matters.

Carbon pricing is a climate solution, but also a political football. Now that an election is underway and the consumer carbon tax has been scrapped, could the federal industrial price on carbon be the next wedge issue? Kate Ervine from Halifax’s Saint Mary’s University helps us go beyond slogans like “axe the tax” to understand what you should know about the industrial price on carbon.

Kids and veggies don’t always go hand in hand, but this after-school workshop is introducing plant-based cooking to children as a climate solution. It’s called EcoCooks. Producer Nick Logan stopped by a session to meet the kids 9-12 who are learning to make, and appreciate, tasty, vegetable-forward food that also cuts emissions. Then, we learn about other community efforts across Canada to put more veggies in the spotlight and onto plates.  

Peace and neutrality offer the best chance for future climate research in Antarctica. That’s what CBC’s international climate correspondent Susan Ormiston learned aboard HMCS Margaret Brooke – a Canadian naval ship carrying 15 Canadian scientists to the South Pole to learn about the southern ocean’s capacity to continue regulating Earth’s climate. Their research is taking place as growing geopolitical tensions threaten to upset the Antarctic Treaty and hamper future conservation efforts on the continent.

It might not sound like a climate job, but mechanical insulators help make buildings more energy efficient. We head out to meet a young woman who trained in the trade through a program set up by the Youth Climate Corps BC. The group is training young people around British Columbia for a wide variety of good, green jobs and hopes to expand across the country.

Fired climate scientist Tom Di Liberto says lives are at risk from extreme weather as more cuts loom over the U.S. government agency responsible for forecasting and much more. Di Liberto lost his job as part of a massive purge by the Trump administration, and worries the layoffs will not only cost the U.S. more money, but will cripple weather forecasting across the continent, leaving many people vulnerable to natural hazards. 

Canada's oil and gas companies are hoping carbon capture and storage will be a big part of the country’s net zero plans. But shipping CO2 through pipelines to storage facilities can come with risks. We go to rural Mississippi to hear about a rare carbon dioxide pipeline breach that was nearly deadly – and find out what Canada can learn from the incident.

There’s a push to see those responsible for intentional destruction of the environment tried in the International Criminal Court, just like war criminals. Three small island nations have proposed making ecocide a crime like genocide and crimes against humanity. But what would that take – and is there a better way to hold people to account for harming the planet and our climate?

With a looming trade war, local fruits and vegetables are attractive. But at what price? Some consumers are suddenly seeing prices skyrocket. Fruit and vegetable farmers are struggling with climate linked extreme weather events. That’s wrecking harvests and driving up production costs all over the world. But customers can help.

A new space race may affect Earth’s climate. As rocket companies, owned by billionaires like Jeff Bezos and Elon Musk, drive the pursuit of energy resources in space, sustainability experts are scrambling to understand the carbon footprint of a quickly ramped up space industry. At the same time, they’re also considering the potential for climate solutions that may exist beyond our planet. It’s a quandary Scottish researcher Andrew Ross Wilson dubs ‘the space sustainability paradox.’

The climate solution that’s heating up across Canada has become an important part of food security and sovereignty. But many are powered by fossil fuels. The City of Fredericton has created a zero emissions greenhouse to grow saplings, and researchers at the University of Windsor are finding more sustainable ways to power them.

People in social housing aren’t always included in conversations about climate solutions. That’s why Zamani Ra is finding ways to draw people from those communities into the environmental movement. The founder of the Toronto-based not-for-profit CEED Canada shares how workshops that start with recycling can make climate action relevant for all.

Sociologist Dana Fisher says disasters like the Los Angeles wildfires and Hurricane Helene can spur community action in the face of the climate crisis. The author of Saving Ourselves: From Climate Shock to Climate Action says individuals coming up with solutions for resilient communities are what give her “apocalyptic optimism.” She shares how we can use the idea in our own personal fight against the climate crisis.

Warmer winters and weird weather have forced organizers of this classic sled dog race to change the route to stay safe in rapidly changing conditions.

Meet the people using TikTok to break up with shopping, and learn why they say affordability is propelling them toward more climate-friendly habits, as they take on the social media challenge of a 'No Buy' year. And author Aja Barber shares stories of her own shopping addiction, how she “saw the light” and what happens when a 'No Buy' year turns into a lifestyle.

Millions of new homes may help the housing crisis. But climate change means reconsidering just where all those new developments should go. Waterfront? Maybe not. Nestled up against the forest? Think again. How to build for our climate future. We hear why to build where and a New Brunswick real estate agent shares what clients need to know about buying and selling safely.

It helps farmers and protects against wildfire. “The world needs to know about biochar,” says one scientist. So, what the heck is this charcoal-like, carbon-storing material? We meet a man on Vancouver Island who’s spending his retirement years making it for his neighbours. Then, producer Rachel Sanders finds out what potential this climate solution holds, what the pitfalls may be and what the challenges are with scaling it up.

From hurricanes to wildfires, extreme weather whips up false and misleading information. When people are left vulnerable after a disaster strikes, they may be more susceptible to being misled about the cause of their strife. And that often means pointing fingers at anything but climate change. We’re delving into the murky world of misinformation and disinformation – and looking for ways to separate climate facts from fiction.

What if we told you there’s a way to lower your food costs while also reducing emissions? Apps that connect shoppers with stores and restaurants selling edible food that would otherwise go to waste offer a climate solution that also makes daily life a little more affordable. We’re testing three popular apps to see how they may help combat the problem of food waste and the harmful greenhouse gas emissions it creates.

We used to take insurance for granted. Climate change is upending that. The L.A. wildfires have people talking about the future of home insurance in the face of more climate-charged disasters. We hear from a woman in Nova Scotia who worries about the future of her current home. And, Canada’s once stable insurance sector is facing uncertainty.

Donald Trump wants more oil and less climate action. But can he really turn back the clean energy transition? CBC climate reporter Inayat Singh breaks down Trump's climate policy changes.

Rural Canada wants in on climate change solutions, but big city ideas don’t always work. A listener in Manitoba knows it takes a village, so he wants ideas tailored for smaller communities. Then we talk to people in three towns that are big on climate action and hear their lessons for others.

There are always a few comments on Instagram telling Corb Lund to ‘stick to music.’ But he finds himself, reluctantly, donning his activist cap. The reason? Water quality near his home in Southwest Alberta, which he says is threatened by coal development.

Come along to Tunisia where climate change is forcing fishers to adapt their livelihoods. We hear how the warming waters of the Mediterranean Sea have meant an influx of invasive species and the loss of old ways of life. A Tunisian-Canadian scientist shares stories from a project that's helping communities organize into cooperatives and find new ways to survive.

Some of Ottawa’s signature climate actions could disappear amidst all the political change ahead. We’ll hear what’s at risk – and why – after the Prime Minister’s decision to step aside. Then, what the fires in Los Angeles can teach Canadians about disasters, climate change and insuring their homes.

Sometimes the truth hurts. And when it comes to fighting climate change, we have obstacles ahead – including the likely reality that global temperatures in 2024 will hit 1.5 C above pre-industrial levels. That’s even before Donald Trump’s return to the White House could bring a big shift in climate policies. But that doesn’t mean the fight is over. David Ho, a professor at the University of Hawaii, explains what the next goal should be and how we could get there.

Will the International Court of Justice’s climate ruling be as influential as Beyoncé? Our youth columnist, Aishwarya Puttur thinks so. She joins guest host Michelle Eliot with her outlook for 2025. Then – story producer Dannielle Piper shares feedback from listeners who weighed in about tiny homes.

They’re on billboards, front pages, TV… but do they pass the sniff test? We dig into the facts behind Alberta’s “Scrap the Cap” campaign. Then, heat and drought could be the Grinch that stole one of New Brunswick’s beloved Christmas tree species. CBC Fredericton journalist Danielle McCreadie shares some solutions farmers and industry are eyeing to climate-proof the balsam fir.

Mining projects in northwestern British Columbia are causing tension downstream in Alaska, where three rivers are home to salmon species and eulachon. Southeast Alaskan tribes are fighting to have a say across the border in Canada when it comes to the environmental assessment of mines upstream. With these watersheds already facing climate impacts, and a rush for critical minerals heating up, is cooperating across borders a climate solution?

Home renos are super popular. That means more waste from old houses. But what if you could salvage that waste and turn it into something useful? That’s what one woman did and now other homeowners are doing it, too. CBC climate reporter Emily Chung shows us how old homes are now being deconstructed to dodge the dump and reduce emissions.

Plastic pollution is a climate issue but the world can’t seem to agree on how to deal with it. Those fighting for a global agreement say the longer we wait, the longer future generations will have plastics polluting their environment, their bodies and contributing to climate change. There are solutions, but people from Indigenous communities around the globe say a good deal needs to include their voices. Then, CBC’s International Climate Correspondent Susan Ormiston's conversation with venture capitalist and entrepreneur Tom Rand about the future of clean tech.

There are a lot of ways to travel long distances. You can carpool, take the bus, ride the train…but for international destinations, figuring out the most climate-friendly method can be tricky. After a listener asked for help, What On Earth’s Dannielle Piper goes cruising for answers.

When a deadly landslide hit Sitka, Alaska in 2015, it sparked conversations about safety and risk. The community has an early warning system for tsunamis. Could it work for landslides? Or would another solution have to be developed? Producer Molly Segal finds out. Then -- with climate change increasing the risk of landslides, we hear how sound waves imperceptible to the human ear can tip us off minutes before the hazard occurs in the Pemberton Valley, north of Whistler, B.C.

Come with us to California where entrepreneurs are sending balloons full of sulfur dioxide into the stratosphere. It’s a form of solar geoengineering known as stratospheric aerosol injection, and the company Make Sunsets isn’t waiting for scientific consensus before they launch. We hear about their business model, and then from the researchers who question both the science and ethics of the practice.

EV fires can be scary and challenging to fight. But they’re not as common as they may seem. Online misinformation and a lack of reliable data can contribute to misconceptions about what happens when an electric vehicle battery fire erupts – and even firefighters aren’t immune.

Have you heard of a 'bike bus'? It's just one of the answers Rachel Sanders found to a listener's concerns about the gridlock that can form around schools.
