We usually bring you failures of the past, but today we're sharing an episode from someone who uncovers failures as they happen. Amy Westervelt is an award-winning investigative climate journalist and the host of Drilled, a true-crime climate change podcast exposing how corporate corruption and political operatives built decades of climate denial and delay. Each season unravels new evidence of deception, disinformation, and the power structures keeping real climate solutions out of reach.

Drilled's latest season, Carbon Cowboys, examines a group of people who've turned climate policy into a profit engine. In September 2025, a group of Brazilian government ministers flew to North Dakota to watch a presentation on a new type of clean energy project, one that promised to help them deliver Brazilian President Lula’s dream of turning Brazil into “the Saudi Arabia of sustainable aviation fuels.” It was the latest in a string of projects from Midwest Republican kingmaker and corn ethanol magnate Bruce Rastetter, whose investments in Brazil might just transform him into a global carbon czar, even as his Summit pipeline carbon project faces fierce opposition from Iowa to North Dakota.

In Tudor England, the line between mathematics and the mystic arts is vanishingly thin. Straddling both worlds is John Dee, a brilliant scholar and astrologer whose intellect grants him access to the highest circles of power. Dee navigates the politics of the court by making bold prophecies, which win him royal favour. But even correct predictions may come with a price - and laying claim to the future is a dangerous game.

Mike Lynch was often lauded as Britain's answer to Bill Gates. Born into a working-class family, Lynch's incredible intellect and passion for computers led him to become a billionaire tech entrepreneur. But behind the scenes, Lynch was a bully who couldn't bear criticism and was prone to creative accounting. When computer giant Hewlett Packard bought his company, Autonomy, it triggered one of the biggest fraud scandals in Silicon Valley history. Tim talks to Katie Prescott, Technology Business Editor at The Times and author of the book The Curious Case of Mike Lynch, about the lessons we can take from a story no one could have predicted.

Tim is running the London Marathon on the 26th of April. To give him a week off to finish training, we're playing this running-themed classic from the archives.

Until the 1960s, it was deemed too "dangerous" for women athletes to run distances longer than 200m - and a marathon would kill them, or leave them unable to have children. Rubbish, of course. But when Kathrine Switzer signed up for the 1967 Boston Marathon, it wasn't the distance that bothered her - it was the enraged race director trying to assault her.

Thanks to pioneers like Kathrine, women have made huge strides in long distance running - and are now challenging the times of men in the very races they were banned from for so very long.

Millionaire-making tech start-ups are most often associated with Silicon Valley. But this software revolution begins on a woman’s kitchen table in rural Britain in the 1960s. Steve Shirley faced extraordinary odds. After escaping Nazi Germany as a child, she later encountered workplace discrimination and endured deep personal tragedy. But she persevered to build a business decades ahead of its time, creating opportunities for hundreds of women.

Tim Harford is joined by Ben Walter, CEO of Chase for Business and host of The Unshakeables podcast, to explore the life, legacy and lessons of an overlooked titan of tech.
