Bumpy flight? Climate change may be to blame

If you're a frequent flier, you may have noticed flights have been getting bumpier lately. A 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 Australia hit severe turbulence and had to make an emergency landing. 

Even as the world warms, oil attracts conflict. Just look to Venezuela and Donald Trump’s moves to control the country’s vast reserves. We delve into the history of "petro-imperialism” and ask whether a planet powered by renewables would be any more peaceful.

From the Best of What On Earth – in remote northern communities, diesel is king. But breakthrough solar energy projects are underway that could begin to reduce fossil fuel reliance. 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.

From the Best of What On Earth – 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.

From the Best of What On Earth – Better transit service could help lower Canada’s emissions. But can more people get on board with buses, trains and subways? We hear how policy changes and behaviour “nudges” can make it happen.

Power is pricey in the Yukon, and solar panels help some homeowners keep costs down. But two years ago, the government paused a program that allowed people to install solar on their roofs, use the electricity they generate and sell some of it back to the electrical grid. We find out what the roadblocks to renewables are in places like Whitehorse, and what the Yukon’s struggle tells us about the challenges of transitioning to clean energy across the country.

In a year-end interview with the CBC’s Rosemary Barton, the prime minister talks about why his plan for more pipelines will help the climate. He also gives his version of what happened behind the scenes when former minister Steven Guilbeaut quit cabinet over the new energy agreement with Alberta.

Why did Volkswagen employees keep mum about the Dieselgate emissions scandal? That’s one of six crimes author Julia Shaw dives into in her latest book, Green Crime: Inside the minds of the people destroying the planet, and how to stop them. She asks, can environmental laws hold criminals accountable or do we need to get tougher?

They popularized, "OK, boomer" but when it comes to climate action, some Gen Z activists find they actually have much in common with their baby boomer counterparts. What On Earth columnist Aishwarya Puttur recently joined the Sue Big Oil campaign. While on the journey to get local governments to file lawsuits against big polluters, Aishwarya met fellow activist and retired journalist Erin Ellis. We get advice from both about overcoming generational stereotypes and uniting for change.

Ferocious fires, monster storms and epic floods. But there were some climate bright spots in 2025 as well. CBC meteorologists Johanna Wagstaffe and Ryan Snoddon break down the impacts of human-caused climate change and how it affected our weather this year. From the rapid intensification of hurricanes and typhoons to rivers and wells running dry in places not accustomed to drought, they explain how climate-charged extreme weather events are reshaping the world along with the way they talk about their forecasts.
