  HOT TAKE: Can Cities Clean Up the Cloud? 23.07.2026 23min

  As the AI boom drives an unprecedented rush for computing power, cities face a critical question: how do we support digital expansion, without derailing net-zero climate goals? Left unregulated, data centers can consume staggering amounts of energy and water, threaten to destabilise power grids, strain local resources, and alienate communities. But it doesn’t have to be like this: city leaders are stepping up to demand both climate-friendly solutions and accountability for big tech. In this H...

  The Shipping Forecast: Climate Edition 19.05.2026 36min

  The Cloud vs the Climate? Lessons from Ireland on the data centre debate 21.04.2026 32min

  As our lives become increasingly digital, the infrastructure powering them is sparking a global debate: we need data centres, but at what cost to the climate and our access to energy?

In this episode of Cities 1.5, we explore how Ireland became the "canary in...

  The Hidden Infrastructure of Urban Resilience 07.04.2026 31min

  Cities aren’t just structures. They’re people. In the rapidly urbanising cities of the global majority, many of those people are migrant workers.

In this week’s Cities 1.5 podcast episode, host David Miller speaks to Ritwika Basu, an environmental social scientist and urbanist who researches this invisible labour in small and...
