Out of the frying planet and into the fire: Stories from the frontlines of climate-driven migration
As global temperatures and sea-levels rise, so to does the frequency of climate-driven migration. The search for a safe, healthy, and prosperous place to live has been a feature of humanity since time immemorial...but an increasingly polarized and toxic global discourse sees migrants being increasingly demonized, which makes it hard to have much-needed conversations around the issue. For many migrants of the climate crisis, cities are the end destination, which means that our urban centres need to be prepared for these new realities by adapting infrastructure, services, and policies to create healthy and resilient environments for all residents - old, and new. It’s way past time to open up the conversation.Image credit: Jody FosterFeatured guests:Spencer Coyne, Mayor of Princeton, BC, Canada.Jazmin Burgess, Director, Inclusive Climate Action; Giovanni Pagani, Senior Manager, Climate and Migration; and Claudia Huerta, Senior Manager for City Diplomacy and Campaigns, Climate and Migration.Links: Simon Kofe’s speech to COP26 - New Scientist (Video)Why cities must prepare for climate migration - C40 Knowledge HubThe far right is weaponizing climate change to argue against immigration - VoxFlooded Princeton, B.C., faces days without heat, says mayor - CBC News (Video)$1.7 billion flood projects still stalled in Abbotsford, Princeton and Merritt - Vancouver SunFuture urban landscapes: Climate migration projections in cities - C40 Knowledge HubC40-MMC Global Mayors Task Force on Climate and Migration - C40The ‘Climate Migration’ Narrative Is Inaccurate, Harmful, and Pervasive.

The Fate of the Inflation Reduction Act in the Second Era of Trump
The United States of America’s second withdrawal from the Paris Climate Accord under the Trump administration has enormous implications for both international and local climate efforts - and the Inflation Reduction Act is also potentially under threat. If the IRA is even partially repealed, it would be a huge step backwards in the fight against the climate crisis. But all is not lost - engaged individuals and organizations are striving to ensure the it stays and place, and more broadly, cities, mayors, and subnational entities are playing a critical role in continuing climate action amidst federal challenges. This coalition of actors are leading the growing resistance movement stateside and globally, proving the importance of local level engagement in the bid to halt climate breakdown.Image credit: Chelsea Matson PhotographyFeatured guests: Kate Johnson, C40 Regional Director for North AmericaAmy Turner, Director of the City's Climate Law Initiative at the Sabin Center, Columbia UniversityLinks:Trump signs order to withdraw US from Paris climate agreement for second time - The GuardianElon Musk Says DOGE Aims to Finish $1 Trillion in Cuts by End of May - BloombergThe Data Hoarders Resisting Trump’s Purge - The New YorkerInflation Reduction Act Archives C40 websiteClimate action and the Inflation Reduction Act: A guide for local government leaders - C40 Knowledge HubOne Year After Trump Decision to Withdraw from Paris Agreement, U.S. Cities Carry Climate Action Forward - C40 websiteAppeals Court Keeps Order Barring Federal Funding Freezes in Place - New York TimesIf 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.

Risky business: How disinformation fanned the flames of the LA wildfires...and why insurance could help mitigate future climate impacts
Risk is an integral part of the human experience…but risk also needs to be managed if we are to live safe, healthy and happy lives. The recent wildfires in Los Angeles were a tragic reminder of the risks that the climate crisis poses to health, homes, habitats, and the lives of human beings. But the risks posed by extreme weather events are also multi-faceted: disinformation in the wake of hurricanes and wildfires can lead to chaos, with online hate transforming into real-life violence. The insurance industry is based on mitigating risk - but for cities with high probabilities of climate impacts such as wildfires, the risk is becoming too great and financially unviable. There is hope, though: insurance can be used as a climate adaptation tool, reducing risk, to better protect people, cities and the planet.

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.

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.
