    Rumble in the Jungle COP

    Full show notes, transcripts, and more at wickedproblems.earth Welcome to Belém, where the world (with some notable exceptions) has gathered to talk about saving the Amazon as if it weren’t already on fire.  Cataloguing the chaos leading up to COP30 Ben Cooke of The Times. His team’s reporting makes clear why the mood isn’t exactly jubilant: the clean-power alliance with zero members, the rainforest pledges with little progress, and the renewed swagger of fossil petrostates.  Even potential bright spots, like the Tropical Forest Forever Facility announced last week, were somewhat dimmed by the spectacle of UK prime minister Keir Starmer reversing an earlier decision not to go to COP, only to make the trip to then announce his government wouldn’t be part of the hoped-for signature initiative out of this event. We chat with Ben about all of that and more. Hosted on Acast. See acast.com/privacy for more information.

  2. Trump nukes Net Zero Shipping

    Trump nukes Net Zero Shipping

    Full show notes and ad-free listening at wickedproblems.earth Shipping is one of those things that’s just supposed to work. Post-Titanic, we created a set of rules that currently are looked after by the International Maritime Organization (IMO), which successfully removed much of the drama from shipping — so successful that Britain’s “Shipping Forecast” is now soothing ASMR for bedtime listening.  But last month at the IMO in London, what should have been a procedural meeting on decarbonising shipping turned into something far messier. According to a Financial Times investigation, U.S. officials didn’t just lobby against a global carbon levy on shipping — they allegedly threatened, intimidated and black-mailed delegates from smaller nations.  Developing-country delegates said they were warned their ships would face higher U.S. port fees, their officials denied visas, and their trade punished if they didn’t abandon support for the Net Zero Framework the IMO had endorsed only six months earlier. “It was like dealing with the Mob,” one diplomat told the FT.   In the end, it worked. The deal — the world’s first carbon-pricing mechanism for global shipping — was postponed for a year. The IMO, normally the most technocratic of international bodies, was left “in a state of complete shock.”  For the uninitiated this may sound arcane. But shipping matters. Roughly 90 % of global trade moves by sea; the sector accounts for about 3 % of global CO₂ emissions — more than Germany — and until now has been largely outside the reach of meaningful climate regulation.   The Net Zero Framework was meant to change that. It had already been provisionally agreed by a majority of countries in April. But by October, something changed. Countries like China, India, Panama, Liberia — and even Greece and Cyprus, who broke with the EU line — suddenly voted to adjourn. news.wickedproblems.uk And the shift didn’t come from nowhere: it came from pressure. From a U.S. administration that now treats climate policy as an existential threat to American interests. 🎧 Who we spoke to Carly Hicks (Chief Strategy & Impact Officer, Opportunity Green) explains how the IMO had once seemed one of the last genuinely global forums where climate ambition could meet technical reality — until the process was capsized by politics. Ariane Morrissey (Senior Editor, Ship.Energy) was in the building as the talks imploded, describing a surreal scene where delegates who came to discuss fuel standards found themselves under threats of sanctions and visa bans. Professor Tristan Smith (University College London) gave the longer-view: this is less a failure of climate tech than a warning shot about the fragility of multilateralism itself. He argues the US may have bought time — but may also have triggered the rise of regional regulation. The EU’s carbon-trading scheme now covers shipping; Singapore and Japan are exploring carbon levies. The patchwork world is arriving faster than the ships can adjust.   🎵 Outro music: “Sailing By” (1963) layered with a long-wave “Shipping Forecast” transmission — that calm voice reading “Viking, North Utsire, South Utsire…” Hosted on Acast.

  3. Laurie Laybourn on Overshooting 1.5°C

    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.earth In 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 Potential 00:00 Global Governance Breakdown 00:36 Welcome to Wicked Problems 00:39 Introducing the Guests: Dave Jones and Constanza Rva 01:05 The Rise of Solar and Battery Technology 01:33 24/7 Solar Power: A Game Changer 01:54 Advancements in Battery Technology 02:51 Economic Competitiveness of Solar and Battery 04:38 Challenges and Innovations in Battery Production 08:17 Global Adoption and Market Dynamics 15:20 Grid vs. Battery: The Trade-Offs 21:05 Solar and Battery in Different Climates 24:27 Implications for Policy and Future Outlook 26:09 Evolution of Battery Storage 27:29 Africa's Solar Boom 27:59 Chinese Solar Exports to Africa 28:52 Utility Scale Solar in Africa 37:50 Challenges and Opportunities in Mexico's Solar Sector 47:26 Global Solar Trends and Future Outlook Hosted on Acast.
