  HOT TAKE: "A Captain never leaves his ship." 20.08.2026 20min

  When the full-scale Russian invasion of Ukraine began in February 2022, local leaders found themselves thrust onto the frontlines of both military defense and environmental catastrophe. Coupled with untold amounts of human suffering, the war has inflicted deep environmental scars - from the destruction of the Kakhovka Dam to the corrosion of municipal water pipes - which many Ukrainian officials refer to as "ecocide." Yet, amidst daily bombardment, energy blackouts, and severed water su...

  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 winds of change are blowing through the world’s maritime hubs…despite some national governments’ efforts to the contrary.

  Creating ecosystems of climate truth: How can cities defend information integrity? 05.05.2026 32min

  From fossil fuel lobbying to coordinated political disinformation campaigns, vested interests have built a profitable disinformation infrastructure designed to spread confusion, polarize debate, and exhaust the public.

  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? These massive facilities are the backbone of everything from streaming to AI, yet they consume staggering amounts of electricity and water, often straining local grids and and in some cases, threatening to derail decarbonisation efforts. 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...

  Whose Streets? Our Streets: Curbing Fossil Fuel Industry Disinformation 24.02.2026 27min

  Mayoral Deep Dive: US cities as climate first responders 27.01.2026 30min
