Dark Machines: AI, Climate Action, and the Future of Our Cities
We live in the age of technology…in the blink of an eye, the Internet and social media have created new opportunities, jobs, and possibilities for connection. But they have also fuelled polarization, persecution, and real-world violence. Artificial intelligence, or AI, promises to turbocharge this revolution. But many questions remain unanswered by the advocates of these new technologies. Can we afford to let AI use infinite amounts of energy? Is it possible to create planetary responsible AI, or is that just a pipe dream? And if the need arises, how can we resist these dark machines?Image credit: This image was AI-generated and does not depict real events.Featured guest:Victor Galaz is an academic and author whose expertise lies at the intersection of governance, climate and technology.

Economic Power, Urban Change: Women who are leading the way forward
In times of uncertainty, leadership is key...but so is vision. As the climate crisis deepens, and people across the world are facing economic hardship and experiencing the increasing impacts of the climate crisis, mapping out an alternative to neoliberal economics, inequality and unmitigated climate breakdown has never been more vital. In our season opener, we speak to two women who are doing just that. Mayor Yvonne Aki-Sawyerr of Freetown is using an innovative, inclusive and data-driven approach to addressing the challenges her city faces, and is a powerful advocate for unlocking urban climate finance. Gaya Herrington is one of the world’s leading voices in the wellbeing economics space, using her platform to argue for the transformation of our economic system away from unsustainable growth to one that prioritizes human and planetary wellbeing. Featured guests:Mayor Yvonne Aki-Sawyerr has served as the Mayor of Freetown, Sierra Leone, since 2018. She is also the Co-Chair of C40 Cities. Gaya Herrington is sustainability researcher, wellbeing economist, thought leader and author of “Five Insights for Avoiding Global Collapse”.Links:What happened at the U20 Summit in Rio?

TRAILER - Cities 1.5: It’s Time to Speak Truth to Power
The world is standing on the brink…the deepening impacts of the climate crisis, rising inequality and increasing levels of economic turmoil are affecting us all. But we now face a new threat: a powerful network of autocrats, billionaires. and demagogues and fossil fuel industry leaders has emerged. This climate crisis denying coalition is weaponising disinformation and manipulating societal distress and uncertainty in a bid to steer us into the arms of far-right populism and away from the global systems change we need. Mayors, cities, academics, scientists, economists, activists and civil society must step up and form a global axis of resistance to challenge those who threaten our way of life…and ultimately, the very survival of our world.Season 5 of Cities 1.5 returns March 11th, with a new episode every Tuesday after that.

How to protect people and planetary health: Lessons from the Peruvian Andes and New Orleans
In this final episode of Season 4 of Cities 1.5, David has conversations with two formidable and inspiring women who are fighting to protect the health of people and the planet from Lima, Peru and New Orleans, USA. As the impacts of the climate crisis hit harder and more frequently, the effects this has on human health also multiply. It is key that urban areas plan and adapt to meet the growing challenges of temperature rise, food insecurity, migration, and more. Of course, extreme weather events often have the most catastrophic consequences for humanity, leading to mass displacement, injury, disease and death. But if the worst happens, it is possible for cities and their residents to unite and rebuild to create a more resilient future…and other communities can learn lessons from their leadership.

How to protect people and planet from misinfluencers in the Age of Disinformation
In this episode of Cities 1.5, David Miller speaks with Pragyna Senapati of Ripple Research about the pervasive impact of climate-related dis- and misinformation. In the past few years, false narratives have been pushed around climate issues in an attempt to derail the policies the world needs to protect the health of people and planet. Ripple has carried out extensive research of these misleading narratives and tactics at the nexus of climate and health and their investigations show clear and actionable strategies and pathways for combating false information through proactive policymaking and climate literacy. The recommendations Ripple and Pragnya offer are key for mayors and city governments to strengthen community resilience and push back on the false claims wielded by climate misinfluencers.

The pan-African transition from fossil fuels to clean energy
In this episode of Cities 1.5, David speaks with two urban climate leaders about the critical issue of energy access in Africa. Despite Africa's low contribution to global emissions, the continent faces a rising energy demand that necessitates a transition to renewable energy in order to ensure its accessibility for all. The fossil fuel industry has a devastating legacy across the African continent, leaving a trail of destruction in its polluting wake...and the oil lobby often presents pipelines to local communities as the only path forward - without disclosing the fact that they’re more unstable, dangerous and expensive than green alternatives. City leaders from diverse communities across this part of the world are fighting to facilitate energy access through innovative local policies to achieve a healthy, sustainable, equitable, future for all residents.Image Credit: Photo by Aaron Jones @ UnsplashFeatured guests:Hilda Flavia Nakabuye is a youth climate, gender and environmental rights activist and founder of the Uganda chapter of Fridays for Future, who is fighting to stop the development of the East African Crude Oil Pipeline.Dorah Modise is the Regional Director for Africa at C40 and is a sustainability enthusiast and expert.LINKS:Access to electricity - International Energy Agency Fridays for Future: UgandaStop the East Africa Crude Oil PipelineGlobal Witness condemns escalating arrests of climate campaigners in Uganda - Global Witness Decarbonising the city’s grid through solar farming and efficiency measures - South Africa, Cape Town, C40 Cities Finance FacilityA renewable energy roadmap for African cities - C40 Knowledge HubC40 Cities launches research on South Africa green jobsCities forge connections with private sector at Africa’s Green Economy Summit - C40 Empowering African youth for a sustaIf you want to learn more about the Journal of City Climate Policy and Economy, please visit our website: https://jccpe.utpjournals.press/ Cities 1.5 is produced by the University of Toronto Press and Cities 1.5 is supported by C40 Cities and the C40 Centre for City Climate Policy and Economy.

Extreme Heat: The Silent Killer
Extreme heat has a profound impact on human health - and the health of the planet, and all who live on it. In this episode, we hear firsthand accounts of extreme heat impacts from Cities 1.5 listeners around the world in Calgary, Canada, Athens, Greece and Rio de Janeiro, Brazil and delve into the terrifying effects of rising temperatures on daily life - such as disease outbreaks and threats to vulnerable residents - especially in cities in the Global South, which face disproportionate risks with only limited resources. We are joined by experts working on the frontlines of resilience and adaptation, from Buenos Aires and Toronto, who share critical insights on how cities are safeguarding vulnerable communities amidst record-breaking heat, and the deadly health consequences that flow from it.Image Credit: Photo by T.H.

In this episode of Cities 1.5, David Miller and his expert guests explore the multifaceted global housing crisis, as well as its ties to the climate crisis and the health of people and planet.
