More than 2,000 years ago, someone sat down and wrote a travel bucket list for the ancient world — suggesting must-see places that we now call The Seven Wonders of the World. It was kind of a Lonely Planet guide of its time, and included the Pyramid of Giza, the Hanging Gardens of Babylon, the lighthouse of Alexandria, and the Temple of Artemis, among others. Historian Bettany Hughes brings monuments and archaeological discoveries back to life in her book,"The Seven Wonders of the Ancient World." *This episode originally aired on Nov. 6, 2024.
For the first two billion years, the Earth didn't have oxygen. That's just one of the many fascinating details Peter Frankopan reveals in his book, "Earth Transformed: An Untold History." The Oxford professor of global history takes us on a multi-million year tour, illustrating the breathtaking ways climate has shaped the Earth and human civilization. How the collapse of a sediment shelf 8,000 years ago isolated what's now Britain from Europe, and its potential influence on the Brexit vote in 2016. Or how climate fluctuations correlate to periods of antisemitic violence. There's a lot to learn in this podcast. Have a listen. *This episode originally aired on Feb. 9, 2026.

Authors Naomi Klein and Astra Taylor want to stop apocalyptic end-of-the-world thinking and its fantasies about colonizing other planets. “We love it here… we want to stay,” they say. They diagnose today's fascism as having an “Armageddon Industrial Complex,” whose main agents are apocalyptic fundamentalists, ethnonationalists, and tech billionaires fixated on creating a super-intelligence at any cost. In their book “End Times Fascism and the Fight for a Living World,” Klein and Taylor explore the convergent forces which not only welcome the end of the world, but seek to accelerate it.

If you ask security expert and author Patrick Lennox the answer is a resounding ‘yes.’ He argues Alberta separatism is less about Western alienation and more about a global effort to destroy liberal democracy. In his book, On Treason, Lennox says what’s unfolding in Alberta is part of a nefarious — and treasonous playbook that’s been used worldwide. To survive the threat, he suggests Canada must call out the traitors and arm ourselves against disinformation and deceit. *This is the final episode in our three-part series asking: what makes a nation?

It depends on who you ask. Until recently empathy was generally considered a positive thing. But a growing number of mostly conservative voices believe empathy can be extremely dangerous — even toxic. Their argument is that empathy can drive irrational thinking and behaviour in public life. The result is a growing battle over empathy in a world that has never seemed to need it more.
