Science fiction isn't fact, no matter what Big Tech tells you

Some of the biggest minds behind AI may have you thinking a Terminator-like robot is coming for us. But literature professor Teresa Heffernan says tech giants have taken their readings of science fiction plots too far, and failed to provide strong evidence for grandiose claims that originated on the pages of science fiction. She argues there are many reasons to fear AI, but an android uprising isn’t one of them. Heffernan is a professor of English language and literature at Saint Mary’s University in Halifax. She delivered the 2026 Wiegand Memorial Foundation Lecture at the Jackman Humanities Institute | University of Toronto.

A machine that could save us from war — and global warming

How? Some scientists believe in the power of nuclear fusion. Environmentally, these machines would have the potential to meet our energy needs with zero carbon cost. But the other advantage is removing a significant motivation behind war — the control of energy sources. Think about it. The Middle East would look a lot different today. This podcast explores what the transition to fusion energy would entail from the challenges, the rewards and the risks. Guest in this episode: Mustafa Bahran is a physics professor at Carleton University in Ottawa. He came to Canada after his life in Yemen became too dangerous. There he founded the Yemeni Scientific Research Foundation and National Atomic Energy Commission. Greg Twinney is the the CEO of General Fusion. Mike Donaldson is senior vice president in technology development at General Fusion. Michael Mann is a climate scientist and director at the Penn Center for Science, Sustainability and the Media. JC Btaiche is founder and CEO of a nuclear fusion company called Fuse.

Will smoky skies spur sharper climate action in Ottawa?

As Ottawa choked on wildfire smoke, climate was left off the agenda in the House of Commons. CBC’s Aaron Wherry explains why it might seem like Canada's climate debate is stuck in the past. We meet 17-year-old Aishwarya Puttur who is fighting for the planet and debuts as our new youth columnist. Producer Molly Segal finds out how to pack a “go bag” in case wildfires force you from your home. An international project out of the University of Victoria aims to share the stories of climate disaster survivors in ways that help them heal. And a boost from the federal government for fossil fuel workers looking to go green.

And the award goes to…

Spoiler alert: the Barbie movie is not about climate change. But it passes the "climate change reality check." We hear why Good Energy developed a climate test for films and find out which two other Oscar-nominated flicks are also winners in this category. Next, a former NASA scientist tells us why a satellite launched into space to detect global methane emissions is a huge deal for the climate. And – Italy's government has just approved an ingredient that could be better for the environment, but not everyone's keen on cricket pizza. Find out how one Quebec lender's decision not to offer mortgages in some high-risk flood zones is sparking calls for Ottawa to protect homeowners in climate-vulnerable places. Finally, we look for answers to your questions about hybrid cars.

We just had the hottest year ever. But is anyone listening?

2023 has broken records, but the warnings can sound like a “broken record.” Will the hottest year in recorded history light a fire under governments to act? And, why peace is on the agenda for the first time at this year’s COP28 talks. We learn how climate disasters breed conflict that hits women the most. In Pakistan the solution lies in education for girls.

Sneaking climate action into your summer block party

How can you talk to your neighbours about climate change and work on solutions together? We hear about a UBC program training people across the country to do just that. And we meet a few of them as they plot to plant “plainclothes environmentalists” at their next community gathering. Then we go back in time to the oil shocks of the 1970s and 1980s for clean energy lessons that have new relevance today. And we meet a community of people making home retrofits a neighbourhood effort.
