Laurie Laybourn on Overshooting 1.5°C
Bonus content at wickedproblems.earth Overshoot, a new four-part documentary series from climate strategist and Wicked Problems alum Laurie Laybourn—goes further than nearly anyone has before. And he came back to unpack some of the key ideas in Overshoot and what he hopes people will do with it.In Overshoot the story starts with the fact that we can no longer avoid the storm, we’ve enetered it. How to survive and steer through it—generation after generation—is the conversation we urgently need to have now. Drawing on interviews with diplomats, scientists, and communities on the frontlines, Laybourn dismantles the win/lose logic that has dominated climate politics since Paris and asks what it means to live in an age of overlapping crises and hard adaptation choices.Our conversation ranges from the myth of Easter Island to the politics of “carbon sucking,” from managed retreat in Wales to the legal aftershocks of 1.5°C’s failure. It’s a clear-eyed look at what comes next—and why, even at the moment of “net zero,” we’ll be living in the most dangerous period in human history. Hosted on Acast.

24/7/365 Dispatchable Solar Is Real. w/ EMBER's Kostantsa Rangelova & Dave Jones
For full show notes, bonus content, and ad-free listening, check out wickedproblems.earthIn this episode of Wicked Problems, host Richard Delevan welcomes Dave Jones and Kostantsa Rangelova from the energy think tank, EMBER. They've spent the past year spreading the good news about the impressive advancements in solar and battery technology, particularly focusing on global trends and potential game-changers in regions such as Africa and Mexico. Despite solar only contributing to 6.6% of Mexico’s electricity, EMBER simulations indicate it could rise to 90% with optimal efficiency. In some spots like Muscat, Las Vegas, or Mexico City, almost all their power, day and night, can now be generated from just solar + battery.The discussion covers the rapid progress and cost reductions in battery technology, the promising shift towards 24/7 solar power, the surge of solar adoption in Africa, and the significant untapped potential in Mexico. The episode highlights the transformative impact of solar and battery technologies on global energy landscapes and emphasizes the urgent need for effective policies to accelerate this transition.00:00 Introduction to Mexico's Solar Potential00:00 Global Governance Breakdown00:36 Welcome to Wicked Problems00:39 Introducing the Guests: Dave Jones and Constanza Rva01:05 The Rise of Solar and Battery Technology01:33 24/7 Solar Power: A Game Changer01:54 Advancements in Battery Technology02:51 Economic Competitiveness of Solar and Battery04:38 Challenges and Innovations in Battery Production08:17 Global Adoption and Market Dynamics15:20 Grid vs. Battery: The Trade-Offs21:05 Solar and Battery in Different Climates24:27 Implications for Policy and Future Outlook26:09 Evolution of Battery Storage27:29 Africa's Solar Boom27:59 Chinese Solar Exports to Africa28:52 Utility Scale Solar in Africa37:50 Challenges and Opportunities in Mexico's Solar Sector47:26 Global Solar Trends and Future Outlook Hosted on Acast.

Laudato Sì at 10, Pope Leo & COP30, w Dr Lorna Gold
Get bonus content at wickedproblems.earth Dr. Lorna Gold is the executive director of the Laudato Sì Movement, which was inspired by the late Pope Francis’ 2015 letter. That document, considered pretty radical for the leader of the Catholic Church to issue at the time, was credited by former Irish president Mary Robinson and others with influencing the Paris Agreement - and you can hear echoes of it as recently as the advisory opinion issued this summer by the International Court of Justice. On its 10th anniversary, Francis’ successor Pope Leo will lead the Raising Hope Conference, 1-3 October in Rome - but also available via livestream - talking about the relevance of its ideas for the situation we’re in now. More than a “Catholic” thing, it will feature people as diverse as Brazil’s climate minister Marina Silva (in the runup to COP30), climate scientist Dr. Katharine Hayhoe, Bill McKibben, Arnold Schwarzenegger, Tuvalu climate minister Dr Maina Talia, Bianca Pitt of SHE Changes Climate, Fossil Fuel Non-Proliferation Treaty president Kumi Naidoo, and more. Somehow, Lorna was able to take a break from organising the event to speak to us. Lorna earned a PhD in economic geography from Glasgow University and author of Climate Generation: Awakening to our Childrens’ Future.It’s a great chat and we think you’ll enjoy it.
