As the winter chill sets in, throngs of Europeans are heading each week to the nearest pond, lake or coastline to dunk themselves voluntarily in freezing cold water. Cold swimming has centuries of history on this continent, but why do it? This week we're delving into the science of why it makes us feel good — but also why it helps so many people through difficult times, with the help of Katharina Smets, audio maker and proud member of Antwerp's biggest cold plunge club. We're also talking about the Vatican's Christmas tree drama and a festive inflation-busting policy in Greece.

We all know this continent has major issues with social mobility. But having a rich ancestor from *six centuries ago* shouldn't make it more likely that you're rich today... should it? This week we speak to Guglielmo Barone, one of the economists behind some fascinating research into this question in Florence. We're also talking about Ursula von der Leyen's 'jobs for the boys' scandal and the road to a shared European cycling policy.

The Swedish oat milk brand Oatly has taken on some eyebrow-raising investments over the past few years. It insists those investments haven’t changed its proud identity as a climate-saving company – but is that really true? In the third and final episode of ‘The Oatly Chronicles’, we investigate a piggy controversy, why oat milk is so damn expensive, and whether Oatly is acting like a big, bad oat milk monopoly. And we ask: what *should* we be eating, to save the planet?

Swedish oat milk company Oatly says it's on a mission to defeat the almighty dairy industry and save the planet. To do that, it claims it needs to grow into a massive corporate success — and it’s willing to take on controversial investments to get there.

In 1994, the world’s first oat milk company was born in Sweden. Three decades later, Oatly is on a high-stakes mission to defeat the dairy industry – by growing into the biggest plant-based brand the world has ever seen.

Can a start-up from Malmö save us all through capitalism? This is the first episode in a three-part series, ‘The Oatly Chronicles’. This week we’re asking: just how much damage is our dairy addiction doing to the planet?

It's easy to feel doomed when it comes to climate change. In her latest book, the Italian political scientist Nathalie Tocci makes the case for cautious optimism about Europe's climate and energy policies. We chat to her this week about the opportunities and challenges of the European Green Deal, as well as how to interpret the death last week of Silvio Berlusconi. We're also talking about a push to ban unpaid internships across the EU, and whether or not we should be blaming Beyoncé for stubbornly high inflation in Sweden.
