What On Earth

Can Canada have it all when it comes to fighting climate change and fossil fuel extraction? That appears to be the goal in Prime Minister Mark Carney's first budget. But Climate Minister Julie Dabrusin says Canada still has cred in the fight to lower emissions, as she heads to the UN's climate conference in Brazil. Then, we hear what's at stake as the world gathers in the Amazon rainforest for COP30, and what climate leadership looks like in 2025.

When Rick and Lori Findlay decided to divest from fossil fuels, their advisor told them they couldn't get the returns they wanted. The Toronto-based couple wants their money choices to both reflect their values and ensure financial stability. Producer Molly Segal follows their story and gets tips on how to make your money work for you and the climate.

As Jamaica moves to rebuild after the storm, the world prepares to gather for its annual climate conference. And amid the stories of death and destruction, Caribbean nations are urging richer countries to help them adapt to climate change. We hear from climate leaders in the Caribbean about what Jamaica is doing to safeguard itself against hurricanes, and why more is needed from world leaders at COP30.

Wasted food has a climate cost bigger than the aviation industry. So how can we toss less – and feed hungry people at the same time? We meet someone who's made it a mission to eat everything she buys, including scraps you might not have ever considered saving for later. Then, we head out with a charity that collects leftover food from grocery stores and passes it along to people in need. And, we hear what's needed for Canada to meet its promise to cut food waste in half by 2030.

You might have heard that using a chatbot to write an email can use a cup of water. So how much water do the new AI data centres being built in Canada use? CBC's Jonathan Montpetit wanted to find out. Instead, he found a murky business with little oversight. But there's also growing opposition to big tech companies using public drinking water, just as climate change makes water more precious than ever.

For the past decade, Canadians have been split 50/50 on new pipelines — that has changed. Two recent opinion polls found roughly three quarters of eligible voters in Canada want at least one new pipeline built to export more fossil fuels. Yet, 70 per cent of people consider climate change a serious threat. IDEAS producer Tom Howell explores the incompatibilities and future scenarios. Fill out the IDEAS listener survey here.

Work is underway to pump seawater onto ice in Nunavut as a way to thicken it in the face of climate change. The experiment is showing some promising results but there are also concerns about its impact on ecosystems. Journalist Alec Luhn travelled onto the ice to see what was happening and to listen to local Indigenous elders about what the ice means to them. He also considers the moral hazard of trying to geoengineer a solution and whether it distracts from the real work needed to cut emissions.

Severe drought and a record-breaking wildfire season have left some remote First Nations in Manitoba cut off from the rest of the province. Planes were grounded by wildfire smoke, and in one boat-access community, the lake was so low the ferry couldn't run. Now, demands from Indigenous leaders are growing for better all-season roads, so the next time climate-fuelled disasters hit, they can get their people out.

The Biljik First Nation in New Brunswick is growing food aplenty thanks to a geodesic dome, community gardens and traditional knowledge. We pay them a visit during pumpkin harvest, to find out how they're winning the fight for food security even as drought threatens the region. Then we cross the country to find out why one bumper crop season is worth celebrating , but also why it's not enough in a changing climate.

If you drove by recent rallies across Canada, you might've wondered: what are they protesting? War? Fossil fuels? Discrimination? There were placards about all of it. Our youth climate action columnist Aishwarya Puttur says banding together could strengthen, not dilute, activists' messages. Then, we hear a similar call to action from renowned primatologist Jane Goodall, who died a few days ago at the age of 91.

Carter Vigh died when wildfire smoke brought on a severe asthma attack. Now his mom is part of an effort to teach other kids about the risks of smoky days and poor air quality. We hear the case for having these kinds of lessons in classrooms everywhere, as the planet warms, creating the hot, dry conditions that lead to longer lasting and more intense fires. And – we meet Roland, another nine-year-old kid with asthma, to find out how climate change is changing his life.

Cori Lausen remembers the first time she saw a bat killed by a wind turbine. It looked like a “black banana peel.” That unlocked a years-long search to understand what was happening and how to fix it. Decades later, Cori says not enough has been done to keep those bat species, which act as natural pest control, from becoming endangered. As wind energy developments continue to pop up in a rush to add renewables to the grid, the question looms: will we be able to do enough to keep both climate solutions on the landscape?

Here's a pitch for a national project that could bring cheaper power to Canadians, reduce emissions, protect our energy sovereignty and promote Indigenous reconciliation. How about a cross-Canada electricity grid powered by wind and solar? What On Earth's Indigenous climate solutions columnist, Melina Laboucan-Massimo, is with a delegation in Ottawa making the case for why this project should be a priority for Mark Carney's government.

The Yukon government is betting on a first-in-Canada solution to help protect Whitehorse from wildfire: a permanent fuel break made of trees. Replacing conifers with the more fire-resistant, deciduous aspen trees, the community hopes it will keep fire from encroaching on the city. But, the process takes a lot of work, starting with harvesting tiny seeds.

Bike lanes equals “bikelash” in parts of Canada. Why? And what is Paris doing right? We travel the path to the heart of the debate about making cities more bicycle friendly, finding out what difference they make to cutting emissions. Then we'll hear about one Calgary man's cycling adventure in Paris (croissants by the Seine anyone?) and what he learned about the city's campaign to build better routes for bikes. We'll also head to a neighborhood meet-up where one enthusiast is trying to teach the youngest to safely ride on Vancouver city streets in hopes of building a stronger cycling culture and community.

They're popping up on balconies across Europe. You can even buy them at IKEA in Germany. Solar panels designed to hang over a railing and plug into your wall. We hear about what's driving the trend, and what's standing in the way of bringing balcony solar to Canada.

The debate over EV adoption reached its peak after the PM put the mandate on ice. Now auto industry leaders want to scrap the rules altogether, while advocates say Canada risks falling behind if it doesn't aggressively pursue electrification. We trace the politicization of EVs over the years with an industry reporter, and ask Electric Mobility Canada whether their goal of more EVs on highways is falling by the roadside.

For more than 35 years, the outspoken American environmentalist has been raising the alarm about the climate crisis, starting with his groundbreaking book The End of Nature. Now Bill McKibben says, for once in his life, he is spreading good news. In his latest book, Here Comes the Sun, Bill explains why the recent boom in solar and wind power has given him hope for the planet's future, and he implores everyone to buy in.

For over a decade, Alberta's capital has been building a groundbreaking sustainable neighbourhood, right in the middle of the city. But some say the development has moved too slowly and is costing too much. With a municipal election looming, one mayoral candidate says the city needs to change course with this prime piece of real estate.

From the Best of What On Earth – They can be noisy. And smelly. And, as Cate Blanchett (yes, Cate Blanchett!) complains, don't they just move “leaves from one place to another, only for them to be blown back again"? Gas-powered leaf blowers create a lot of opinions and a lot of emissions. Molly Segal takes us through why they're so particularly polluting and unhealthy. And, she explores the solutions underway — from political bans to incentives for switching to electric.

A hiking ban in Nova Scotia is getting lots of attention this summer, from Joe Rogan to former Freedom Convoy supporters. Although the ban has now been lifted for parts of the province, the rules have ignited an international debate about government overreach during fire season. Some Nova Scotians are calling the criticism fearmongering and want outsiders to butt out of the province's affairs. We hear from an emergency management expert who says governments should prepare for more backlash against wildfire rules as the climate changes and summers become potentially more restricted.

From the Best of What On Earth - A tale of two First Nations pushed to live on lands that face increasing flooding risks as the climate changes. We hear their stories of survival and their fight for justice and a safe place to live. Also, want to travel cargo? As in cruising onboard a cargo ship? It may just make for a greener vacation.

Communities on Reddit and elsewhere are crowdsourcing reviews and recommendations in an effort to find the “best” version of, well, everything. It's partly an ode to items that have withstood the test of time, and partly a quest for durability, longevity and repairability – all in an effort to save money, and the environment.

From the Best of What On Earth – The coastal city of Aberdeen, Scotland, has long made its living off the North Sea, first from fishing then oil and gas. Now, a new transition is underway: offshore wind. But who wins and who loses? Laura Lynch has some surprising conversations on the windy shores.

Shutting off the electricity to prevent wildfires is becoming the new normal in some west coast states, leaving thousands living through extreme heat without air conditioning or medical devices. Now, policies allowing this to happen are coming to B.C., Alberta and possibly other parts of Canada. We hear from people who say this could put their lives at risk, and get some advice on how to cope.

From the Best of What On Earth - A CBC News investigation found unsafe temperatures in homes across Canada during the summer, with people often living in dangerous heat for long stretches of time with no relief. Reporter Tara Carman shares stories of people who suffered, including a man who died after his home was close to 30 degrees for several weeks.

Polar bears, bowhead whales, melting sea ice – the students on these ships see it all. We hear from two students sailing across the Davis Strait from Nunavut to Greenland about what life is like onboard the Students On Ice ships. We also hear from a former student about how her trip sparked her career in climate solutions, and from the founder of the program about how the polar regions have changed since he started the expeditions 25 years ago.

From cuts to U.S. weather agencies, to the rise of AI predictions, there are big changes in the world of extreme weather forecasting. We talk with the former head of the Canadian Hurricane Centre, about what it all means for our ability to warn Canadians before hurricanes hit. Then we hear how well the current AI forecasting models can predict these weather events — and how the technology needs to improve.

In 2023 Nova Scotia pledged to investigate how Black and Indigenous people in the province are disproportionately affected by pollution and environmental hazards, including climate change. As part of our "Best of What On Earth" series, we revisit our interview with the chair of the panel tasked with that work. Then we hear an update from one of the people who took part, who says the province is now withholding crucial information.

From the Best of What On Earth – 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.

Move the propane tank, clear the toys, replace the deck. When guest host Johanna Wagstaffe asks a FireSmart assessor for advice on safeguarding her home from wildfires, she's left with a long to-do list – from simple to pricey. Then, we visit Canada's first FireSmart community, Logan Lake, to hear how those efforts helped protect it from a mega fire. And we ask whether funding for wildfire prevention is keeping up with the growing risk.

After more than four decades of activism and advocacy, Suzuki is one of the most renowned and respected voices in the environmental movement. So when he says it's too late to stop climate change, people take notice. And that's now exactly what he's saying.He's delivering this message as Prime Minister Mark Carney's government focuses on fast-tracking major projects it deems to be of national interest, which could include a new pipeline for fossil fuels from Alberta. Suzuki says that, despite his understanding of the climate crisis, Carney — like all of us — is trapped by the economic and political systems we've created. And for Suzuki, our only hope for survival is to scrap those systems entirely.In this special episode from our colleagues at Front Burner, David Suzuki joins Jayme Poisson for a wide-ranging discussion from what a world of irreversible climate change looks like, to what he describes as the "madness" of continued investment in fossil fuels, to the lessons environmentalists of the future can take from the past.Front Burner is CBC's daily news podcast that takes listeners deep into the stories shaping Canada and the world.

From the Best of What On Earth – Wildland firefighters say working conditions threaten the safety of crew and the public in Alberta. People on the front lines say they're losing team members to other employers that offer better pay, benefits and long-term opportunities – leaving what they call a gap in experience on the crews. In the midst of what is shaping up to be Canada's second-worst wildfire season, we revisit our conversation.

Planning to hit the road this summer? How about travelling 8,500 kilometres in an EV? That's what Carl Duivenvoorden is doing on his zero emissions journey across Canada. He shares some of the tips he's learned along the way, including the best and worst places for charging, and explains why EV road tripping is an efficient — and cheaper — option for the adventurous. After that, we'll take a trip down the EV misinformation highway, in search of answers to common claims that electric vehicles aren't really that green.

From the Best of What On Earth – Warming waters are threatening an irreplaceable species for Indigenous people in Canada's north. But First Nations leaders in Yukon have become leaders in protecting and demanding better care for the Chinook salmon – a vital part of their traditional diets and culture. This story is a part of the Overheated series, put together with CBC Radio's Quirks & Quarks and White Coat, Black Art to examine how heat is changing lives.

The Salinas Grandes in northern Argentina is home to large deposits of lithium, a key mineral in the fight against climate change. But Indigenous leaders in the region say mining the mineral could harm their water supply. We hear how communities are pushing back against potential lithium extraction. And, how new methods of mining are being tested - ways of extracting lithium that aren't so damaging to the local environment.

In the thick of the deadly flooding along the Guadalupe River, questions emerged about what could have been done differently. Republican politicians are pushing back vigorously, calling accountability questions “partisan games.” But one climate expert in the state says Texas needs to ask the tough questions right now before the next natural disaster hits – questions about the political power of fossil fuel industries and what that means for how politicians talk about, and prepare for climate change.

From the Best of What On Earth – Will your carbon footprint follow you to your grave? Not if you have a green burial. Environmentally friendly funeral options are growing in popularity. In our Atlantic Journalism Award-winning documentary, we hear why some Canadians are choosing eco-conscious interments, and how you can arrange to be laid to rest naturally.

To mark the show's anniversary, we ask what Canada has learned about tackling climate change since our debut in 2020, starting with lessons from the Covid-19 pandemic. And, we discuss what climate action could look like over the next five years.

From the Best of What On Earth — Glaciers are rapidly retreating in Canada's Rockies and that's making it more hazardous to navigate some alpine routes. In this documentary, we visit Banff National Park to meet guides who are adapting to the different ways climate change is altering a once familiar landscape. Plus, what you need to know about how older people can stay safe in extreme heat.

If Canada wants to be net zero by 2050, more than a million small businesses will have to make the green transition. And while some intrepid business owners are already trying their best to navigate a more eco-friendly path, others say it's a big ask, especially when many are already struggling to balance the needs of price-wary shoppers with a thin bottom line. We'll dive into their journey, and learn more about the supports that could change the game.

A year and a half ago, Adrienne Crowder caught an episode we did about a free university course on climate change. She took it, she loved it, and she wanted more. So, she started a network amongst her classmates: ordinary Canadians who support each other to make change in their lives. We hear from many of them, as we kick off special coverage to mark five years of What On Earth.
