Outrage + Optimism: The Climate Podcast

Can the rules keep up?: Lawsuits, LLMs and the looming oil recession

An unprecedented government move to outrun the courts. A country racing to write AI into its constitution. And a global energy crisis that's already moved faster than any possible fix. Are our institutions and the rules they rest on still fit for the world they're supposed to protect? This week, Tom Rivett-Carnac, Christiana Figueres, and Paul Dickinson look at three stories the headlines may be missing. In New Zealand, the government has moved to retroactively kill a landmark climate lawsuit -  before it even reaches trial. Tom shares a voice note from ClientEarth CEO Laura Clarke [https://www.clientearth.org/about/who-we-are/experts/laura-clarke/] who gives us the inside scoop on what is actually at stake. If this works, where does it end? Then Greece, which wants to write a legally binding obligation for human-centred AI into its constitution. But can a national document meaningfully govern a borderless technology? And as we increasingly rely on AI for our information, where do these large language models actually go for their climate science? Finally, the Strait of Hormuz. Financial markets think the situation is priced in. Geopolitical analysts disagree. We ask which sectors might unexpectedly accelerate the energy transition, why the climate movement seems frozen at exactly the moment it should be loudest, and whether this decade's decisive window is already starting to close.

The Jet Fuel Crisis: What’s next for aviation?

Are flights across the world about to be grounded? Is a terrible war about to create an unlikely good news story for the climate? As conflict in the Middle East threatens the Strait of Hormuz, jet fuel shortages are forcing aviation to confront a structural vulnerability it has spent decades avoiding. This week, Tom Rivett-Carnac, Christiana Figueres and Paul Dickinson examine what the shortage reveals: aviation's near-total dependence on fossil fuels, the structural reasons it has proved so hard to break, and whether it’s ever going to be possible to fix.  They speak with Karel Bockstael [https://nl.linkedin.com/in/karel-bockstael-034547171] and Roxanne van Rijn [https://www.linkedin.com/in/roxannevanrijn/?locale=nl], former aviation insiders who co-founded Call Aviation to Action, a movement designed to reach the industry’s senior leaders and push for much-needed change. They explain why kerosene remains the only viable option for long-haul flight, how thin margins trap airlines into opposing the very regulation they need, and why this fuel shock may be the scarcity event that finally forces the model to shift.  Could this crisis become aviation’s turning point? And in a world where up to 80% of people have never set foot on a plane - and 1% account for half of all aviation emissions - what would a truly fair future for flight actually look like?

David Attenborough at 100

Monarch butterflies crossing a continent. Peregrine falcons above Manhattan. A giant lemur most of the world had never heard of, until one man pointed a camera at it. For seventy years, Sir David Attenborough has been asking us to look - really look - at the world we share with three and a half billion years' worth of other life.  This week, Christiana Figueres, Tom Rivett-Carnac, and Paul Dickinson mark the 100th birthday of the world’s longest-serving television presenter. To celebrate, they're reaching into the archives to share the very first episode of the podcast - a conversation recorded in person with their friend Sir David himself, at the Attenborough Centre in Cambridge in 2019. They also take stock of seven years of Outrage + Optimism, and on a world that’s changed since that first episode dropped. What's moved faster than anyone expected, what's gone sideways, and what still keeps us at night? Then Sir David. On why young people's outrage is entirely justified. On what the natural world actually needs from us. On the rare moments in history when nations chose agreement over conflict. And on why understanding might be the thing that saves us.

“This is civilisation changing stuff”: Is AMOC the hardest climate story to tell?

Europe plunged into a deep freeze. Life as we know it upended. The 2004 film ‘The Day After Tomorrow’ gave a generation of terrified journalists an impossible task: how do you communicate the counter intuitive threat of dramatically colder winters caused by global warming? David Shukman [https://davidshukman.com/] was one of them. This week, Tom Rivett-Carnac is joined by the veteran BBC Science Editor and author of the upcoming ‘The Response’, to explore the Atlantic Meridional Overturning Circulation, or AMOC: the vast system of currents that helps regulate weather, rainfall and temperature across the Atlantic and far beyond. Recent research suggests it may be weakening faster than previously understood - with potentially profound consequences for food systems, ecosystems and global stability. They speak with Dr Willem Huiskamp [https://www.pik-potsdam.de/members/huiskamp] of the Potsdam Institute for Climate Impact Research, who explains what AMOC does, and what a much weaker system could mean in practice. Then Tom and David reflect on the harder questions. How do we communicate a risk this vast and uncertain without paralysing people or losing them entirely? Are we socially and politically prepared for -50C winters in parts of Europe? And are we even capable of responding to a threat that may unfold over decades rather than across news cycles and political terms?  Learn More: 🌊 Discover more about the Atlantic Meridional Overturning Circulation [https://oceanservice.noaa.gov/facts/amoc.html] and why scientists are watching it closely  🔎 Read the latest paper [https://www.science.org/doi/10.1126/sciadv.adx4298] referenced in this episode, which projects an approximate 50% weakening of AMOC by the end of the century 📘 Check out David’s book, The Response [https://www.penguin.co.uk/books/469146/the-response-by-shukman-david/9781529144284], which will be published by Witness Books on 7th May 🎤 Leave us your voice notes and questions for upcoming episodes on SpeakPipe [https://www.speakpipe.com/OutrageandOptimism] Join the conversation: Instagram @outrageoptimism [https://www.instagram.com/outrageoptimism/?hl=en] LinkedIn @outrageoptimism [https://uk.linkedin.com/company/outrageoptimism] Or get in touch with us via this form [https://www.globaloptimism.com/contact?hsLang=en].

Beyond the Oil Crisis: What’s actually blocking the transition?

The Iran crisis continues to prove how dangerously dependent the global economy is on fossil fuels. But what will it actually take to move beyond them? In this episode, Christiana Figueres, Tom Rivett-Carnac and Paul Dickinson look at what the latest oil shock continues to reveal. And they turn to the upcoming First Conference on the Transition Away from Fossil Fuels in Santa Marta, where governments, campaigners and other actors are gathering to build new relationships and explore new routes towards a just transition in an age of geopolitical instability. Christiana speaks with former President of Ireland Mary Robinson [https://theelders.org/profile/mary-robinson] and Ugandan climate activist Vanessa Nakate [https://www.unicef.org/goodwill-ambassadors/vanessa-nakate], who lay out the big structural barriers still slowing the shift. From debt traps that make fossil fuel extraction a financial necessity, to vested interests, and subsidies flowing in the wrong direction. The evidence is clear: the transition is happening. The question is, will it be political machinations or economic urgency that determines how fast?  Learn More: 🌍 Explore the official page [https://transitionawayconference.com/] for the First Conference on Transitioning Away from Fossil Fuels, including its aims, format and participants 🛢️ Understand why the Strait of Hormuz matters so much through the IEA’s Oil Market Report hub [https://www.iea.org/search?q=Oil+market+report] 📜 Read the UNFCCC summary of the 2023 COP28 agreement [https://unfccc.int/news/cop28-agreement-signals-beginning-of-the-end-of-the-fossil-fuel-era], which for the first time called for “transitioning away from fossil fuels in energy systems” ⚡ See the figures behind the boom in renewables in BloombergNEF’s latest Energy Transition Investment Trends [https://about.bnef.com/insights/clean-energy/bloombergnef-finds-global-energy-transition-investment-reached-record-2-3-trillion-in-2025-up-8-from-2024/] 🎤 Leave us your voice notes and questions for upcoming episodes on SpeakPipe [https://www.speakpipe.com/OutrageandOptimism] Join the conversation: Instagram @outrageoptimism [https://www.instagram.com/outrageoptimism/?hl=en] LinkedIn @outrageoptimism [https://uk.linkedin.com/company/outrageoptimism] Or get in touch with us via this form [https://www.globaloptimism.com/contact?hsLang=en].
