Lessons learned from Canada’s gnarliest wildfires 11.07.2026 26:29
Jesse Winter became a photojournalist so he could see wildfires firsthand. He got more than he bargained for, including documenting the aftermath of a young firefighter’s death. His new book, Wildfire: Dispatches from a Country Ablaze details how climate change, along with decades of poor forest practices, has set the table for devastating fires. We hear about the challenges for Canada’s wildland...
Why your flight feels more like a rollercoaster these days 08.07.2026 25:24
From the Best of What On Earth – If you're a frequent flier, you may have noticed flights have been getting rockier lately. The potential culprit? Climate change. CBC producer Julia Pagel finds out how warming temperatures are making air turbulence worse, and what can be done about it. But first, she takes us back to 2019, when dozens of passengers were injured after an Air Canada flight bound for...
Heat is killing us. Is air conditioning the only fix? 04.07.2026 24:16
As Europe tallies thousands of deaths, there are calls for way more AC. In North America, where a heat dome is disrupting holidays, air conditioning is common — but it can also contribute to inequity and emissions. As a Chief Heat Ambassador, Jane Gilbert is grappling with this paradox. She shares ways to protect lives as climate change heats our world.
Farewell to Laura Lynch, who’s had one helluva career 01.07.2026 27:39
What On Earth will continue, but host Laura Lynch is moving on. For the last six years, Laura has brought you climate solutions stories, and before that she covered world events for decades, including the 9/11 attacks and the Arab Spring. Now, Laura is retiring (although she prefers to say heading off to new adventures). Today we celebrate her career through the stories she’s covered and the peopl...
Face to face with the disappearing whales 27.06.2026 25:29
Laura heads out on a boat, searching for grey whales. Plot twist: they find her. We hear why scientists are sounding the alarm about the fate of these massive mammals, and why they think climate change is part of the problem. But researchers and communities on Canada’s west coast have solutions to protect the populations that remain.
Five years after the deadly heat dome, are we any safer? 24.06.2026 32:41
Cindy MacDougall calls herself a climate change casualty. If it wasn’t for her husband’s quick action during the 2021 Western Canada heat dome, she might not have survived the disaster. Still, her heart is permanently damaged. We hear what happened, and how she’s working to share the stories of others who suffered. Then, we hear about the progress in British Columbia on the “right to cool” for tho...
How to protect wildland firefighters from cancer risk 20.06.2026 22:02
Years after working in smoky, sooty conditions controlling fires, workers can experience the adverse health effects of the job. Proving the link can be difficult. But now in British Columbia, wildland firefighters are getting early cancer screening and expanded workers compensation coverage for cancer. With climate change contributing to the hot, dry conditions that lead to longer, more intense fi...
Can movie magic move the needle on climate change? 17.06.2026 25:45
Our youth climate action columnist Aishwarya Puttur says yes it can. She’s seen young people in the entertainment industry taking up the climate cause lately – from local film festivals to the United Nations – and shares stories about how she’s seen this type of storytelling make a difference.
Should you tattle on your neighbour in the name of climate? 13.06.2026 27:51
As Vancouverites see people watering their lawns during a drought, it’s a question they’re asking themselves. While cities in British Columbia take drastic measures to limit water use, Laura heads to the watershed to learn how conservation can help keep the taps on. But it’s not the only approach that Canadians are using to tackle water shortages. In south central Manitoba, a modified wetland is f...
This footballer wants fossil fuels out of the World Cup 10.06.2026 27:31
Tessel Middag wants her sport to be a force for good. But she says that’s hard to imagine when FIFA’s “Major Worldwide Partner” for the 2026 World Cup is Saudi state oil company, Aramco. And it’s not just Tessel. Advocates like Frank Huisingh feel uneasy watching athletes compete in extreme heat while flanked by advertisements for the globe's leading oil corporation. But as the world continues to...
Here’s your fire season forecast 06.06.2026 24:06
Can a weekly fire weather outlook help Canadian communities learn to live with fire? Mike Flannigan, wildfire forecaster and professor at Thompson Rivers University, thinks so. A weekly forecast is one of the things that gives him hope that people across Canada can be better prepared to respond to wildfire risk this summer as conditions start to look like “Dante’s circles of hell.” Then – we hear...
Is lightning in a box a climate solution for farmers? 03.06.2026 27:58
Farmers are using an old trick as a new way to grow food and reduce emissions. Lightning sparked inside a box helps create fertilizer with less cost to the planet. But it’s controversial, with critics calling it “snake oil.” Those who love it say the proof is in the plants they harvest. Story producer Jennifer Wilson digs into whether lightning in a box is the real thing.
Is Ottawa backsliding on Indigenous clean energy promises? 30.05.2026 25:21

Who killed the 21st century milkman? 27.05.2026 28:04
A system from another era was the inspiration for a modern-day solution to the pileup of plastic in the world. The milkman once delivered cold bottles of milk to the doorsteps of homes and took the empty ones away. So what happened to the idea? CBC producer Peter Mitton delivers the (non-plastic) goods in his feature documentary.
Trump is wrong. Climate action is working 23.05.2026 25:10
Donald Trump claimed on social media that climate scientists were “WRONG! WRONG! WRONG!” about their global warming projections. But climate scientist Zeke Hausfather says the experts were not wrong, and the new projections are not entirely bad news. The world has made some progress in reducing emissions, though he says we still have a long way to go when it comes to stabilizing the climate. Then,...
How kids can save themselves from climate anxiety 20.05.2026 25:23
Twelve-year-old Kiké Dueck once had such bad climate anxiety that they didn’t want to eat or go to school. But then they found a solution. Kiké got involved in lobbying Regina city hall for greener transit and even joined a legal case to try to stop Saskatchewan’s support of coal plants. Kiké is not the only child taking the government to task - and to court. In fact, Kiké is part of a group led b...
Why more trees - not fewer - could save a city from fire 16.05.2026 29:06
Ten years ago this month the Horse River Wildfire burned through Fort McMurray and into the Canadian consciousness. We hear why experts say it’s the fire that taught us nowhere is safe, even busy urban centres. And, from the best of What On Earth: The Yukon government is betting on a first-in-Canada solution to help protect Whitehorse from wildfire: a permanent fuel break made of trees. But, the p...
Why can’t more Canadian kids ride electric school buses? 13.05.2026 27:47
Hop on board an electric school bus in Richmond B.C. and meet a driver who says “once you start driving them, you don’t want to go back.” So why aren’t more kids across Canada riding to school on these quieter and cleaner buses? Producer Nick Logan takes a spin through the successes and ongoing challenges with electrifying Canada’s school bus fleets. Then, we hear from an EV advocate about the pol...
Here’s how it feels to get caught in an avalanche 09.05.2026 25:44
Backcountry skier Hannah Hughes realized she couldn’t fight the wall of snow when it hit her. She survived but the experience has her rethinking her relationship with risk, and she isn’t alone. The 2025-2026 ski season has been a brutal year for avalanche-related deaths in parts of the world. Some scientists say climate change is now one more factor to consider when heading out into the backcountr...
Goodbye, dystopia. Hello, 'thrutopia' 06.05.2026 25:51
Tired of stories about bleak, hopeless futures? You’re not alone. Writers are ditching dystopian narratives for a fresh take on climate fiction. Enter ‘thrutopia,’ a new genre that aims to chart a middle path through the worst impacts of climate change. And maybe even envision a future where humanity both survives and thrives. Climate writer Sanjana Sekhar and media watcher Lucy Stone talk about g...
A ‘breath of hope’ in the climate fight 02.05.2026 24:44
Nations gathered in Colombia to chart a path to a cleaner future. Many say this ‘coalition of the willing’ could speed the transition away from fossil fuels. But there are those who say that Canada’s lack of ambition will mean we’re left behind in the switch to renewables. And others who say global Indigenous voices still don’t have enough sway in the climate fight.
Suzanne Simard says it’s time for a fresh look at forestry 29.04.2026 27:27

Not only is she defending her work as a scientist, she’s back with a new book expanding on it. Together with Tsimshian scientist Teresa Ryan, Kwakwaka’wakw artist and hereditary chief Rande Cook, and lawyer Chris Rusnak, she takes to the stage at UBC with our own Laur...
Critics say the math isn’t mathing on Ottawa’s climate plans 25.04.2026 26:38
After a year in office, climate minister Julie Dabrusin says she’s proud of her record. But critics say more pipelines, less progress on emissions cuts and other moves overshadow efforts to protect nature and boost renewable energy. We challenge the minister’s claims that her government is making Canada “climate competitive.”
Can baby coral nurseries rescue reefs from climate change? 22.04.2026 23:49
Coral reefs support marine life — and livelihoods. But bleaching caused by warming oceans is putting both under threat. Fishing communities in Mauritius and Seychelles are feeling it more than almost anywhere else. But there are ambitious efforts underway in these island nations to restore some of what’s been lost, to protect the health of the ecosystems and the local economies.
Outdoor skating rinks are on thin ice 18.04.2026 25:58
Climate change is melting away winter, but a new documentary summons the magic of the most Canadian of frozen delights: the outdoor skating rink. For Earth Day, we speak with the filmmaker behind Icemakers about why he was driven to share stories about the people who spend hours each winter making ice for their families and communities – a job that’s getting harder with warmer winters. And we meet...
