What if we could not only listen to the rest of nature, but actually understand it?

From decoding whale songs to giving nature a legal voice, the possibilities are tantalising - and they may not be as far-fetched as they sound. That’s why the Earth Species Project (ESP) is racing to use artificial intelligence to translate the communication of other species before they fall silent.

How can this cutting edge technology analyse data that would take human researchers a lifetime? And how might findings feed into emerging ideas about ecocentric governance and earth law? We hear from ESP’s Aza Raskin (Co-founder), Jane Lawton (Managing Director) and Olivier Pietquin (Chief Scientist) about this extraordinary mission, and the tools they’re using to achieve the previously unimaginable.

Plus, Christiana Figueres, Tom Rivett-Carnac, and Paul Dickinson explore the promises and pitfalls of AI: its energy demands, its unpredictable impacts on democracy and capitalism, and its potential to become a ‘Galileo moment’ in how humans relate to the living world.

This episode features recordings of animal species - some of which were used in the training of ESP’s NatureLM-Audio model.

What’s really in the food on our plates? The journey to our supermarket shelves is one of broken economics, environmental destruction, and social injustice.

But what if agriculture could look completely different?

This week, Christiana Figueres and Paul Dickinson travel to Umbria, Italy, to visit QuintoSapore, a farm founded by twin brothers Nicola and Alessandro. After leaving city careers, they set out to reinvent farming: growing food in a way that respects living things, restores soil, and values the people who work the land.

Instead of short-term, precarious labour, they offer full-time contracts, living wages, and community. Instead of chemical fertilisers and pesticides, they look to biomimicry, biochar, and heirloom seeds - not discovering, but remembering the old ways and learning from nature.

From a revelation in a drought-stricken woodland, to redefining what it means to “grow” rather than “produce” food, this episode is a reminder that the path to climate resilience runs straight through our fields.

As global temperatures continue to skyrocket, the once unthinkable is now within view: overshooting 1.5°C of warming. This limit, set out in the Paris Agreement, has defined a decade of climate action, but is fast approaching. So what happens next?

This week, Tom, Christiana and Paul grapple with the latest science, the looming risks of climate tipping points, and the urgent need to prepare for the worst - even while hoping and working for the best. They’re joined by Ricken Patel, former Founding CEO of global activism nonprofit Avaaz, who is now calling us to take the possibility of overshoot seriously, and to build the political, technological and social capacity to bring temperatures back down.

From nature-based solutions to novel carbon dioxide removal and solar radiation management, this episode considers the broad spectrum of options on the table, and the challenges they present. Why has climate contingency planning been missing from the political debate? And does simply talking about it risk slowing climate action?

These aren’t just questions of what we might do in the future - but of what we’re prepared to act on now.

Isn’t climate change just part of a natural cycle? Weren’t CO2 levels much higher in the past? And, even if we should be worried, can one person really make a difference?

Lies travel faster than facts. We’ve all been confronted by someone who doesn’t ‘believe the science’ and asks questions like these - but how do we change their minds?

A powerful report from the International Panel on the Information Environment (IPIE) warns how coordinated misinformation campaigns are eroding public understanding and slowing climate progress around the world. And as anyone working in or advocating for climate action knows, persistent myths and misunderstandings continue to thrive - even as the science gets clearer, the stakes get higher, and the crisis becomes more urgent. What’s clear is that disinformation is a weapon, and it’s being targeted at climate action. 

So this week, Christiana Figueres and Paul Dickinson tackle some of the most common (and frustrating) climate myths - where do they come from, why are they misleading, and how can we win the battle against them?

As record heat scorches the US, Trump’s government is making things dramatically worse. We break down the devastating implications of the One Big Beautiful Bill, the reversal of the Environmental Protection Agency’s endangerment finding, and a potential US withdrawal from all UN agencies. It’s a full-blown climate backslide with global consequences.

Then, we bring you a conversation with the brilliant Maggie Baird - actor, producer, climate activist, and mother of Billie Eilish and Finneas. Maggie joins us backstage at the Co-op Live Arena in Manchester, where Billie’s shows are going plant-based, thanks to Maggie’s food justice initiative Support + Feed. We talk food, parenting, the power of culture to shift climate narratives, and how to stay hopeful - even when it feels like the world is falling apart.

“An Existential Problem of Planetary Proportions”

International Court of Justice President Yuji Iwasawa just delivered a landmark advisory opinion on climate change and human rights - one that could transform global climate action and accountability.

A dancing and crying Christiana Figueres is joined by Tom Rivett-Carnac and Paul Dickinson, to react in real-time, and speak with two of the lawyers who helped make it happen. 

Fresh from the courtroom, Julian Aguon, the indigenous human rights lawyer who represented Pacific nations, and Jennifer Robinson, barrister for Vanuatu and the Marshall Islands, bring their raw, unfiltered reactions to this history-making ruling (before heading off to celebrate).

As governments, legal teams, and corporate leaders worldwide scramble to interpret its implications, we have everything you need to know about what just happened in The Hague.

The ICJ’s unanimous opinion states:

• Climate action is now a legal duty: States are obligated under international law to prevent dangerous climate change.
• 1.5°C has legal weight: States must pursue their “highest possible ambition” in their Nationally Determined Contributions and ensure collective measures can limit warming to 1.5°C.
• Failure to act is unlawful: Granting fossil fuel licenses, providing subsidies, or failing to regulate emissions may constitute an internationally wrongful act.
• Reparations are possible: Countries could be required to compensate or remedy the damage caused by their emissions - anywhere in the world.

Could this be the legal tipping point that forces governments to act? Across capitals and boardrooms, the conversations have already started - and what happens next could reshape how nations and companies are held to account. Listen in and join us as this story unfolds.

Can a pilot really be the change-maker who helps us to holiday nearer home? Why aren’t governments and institutions doing more to help climate activists? And can climate progress happen without sacrificing prosperity, especially in countries like Brazil?

Christiana Figueres, Paul Dickinson and guest host Fiona McRaith (Director of The Climate Pledge at Global Optimism) are back with more of the knottiest and most urgent questions you’ve ever sent us.

Plus: are the world’s biggest financial institutions abandoning climate action? Sue Reid (Climate Finance Advisor at Global Optimism) explains how banks and insurers are reacting to political pressure, why some net zero alliances appear to be fracturing, and why “green hushing” doesn’t mean giving up entirely.

And: from climate visas to sponge cities, adaptation is finally rising on the global agenda - but is it fast or fair enough? Irene Suárez Pérez (Senior Advisor to Groundswell) walks us through some of the global hotspots of climate resilience, and why adaptation isn’t a consolation prize.

We’re handing the mic over to you on this week’s Outrage + Optimism: The Climate Podcast.

In this special Q&A episode, Christiana Figueres, Paul Dickinson and guest host Fiona McRaith (Director of The Climate Pledge at Global Optimism) respond to thought-provoking questions from listeners around the world. They consider the future of the COP model, whether the Pacific concept of vā may offer a better way to think about our local and global relationships, what a multipolar world might mean for climate diplomacy, and much more. Plus, friend of the show Nigel Topping (Founder of Ambition Loop) helps to explain why UK electricity prices are tied to gas - and how we can fix it.

From the philosophical to the practical, this is a wide-ranging conversation about where climate progress is stalling, where it’s surging forward, and how global cooperation might evolve in the years ahead.

In a world-first, the International Court of Justice is preparing to deliver an advisory opinion on climate change and human rights - all thanks to a youth-led campaign that began thousands of miles from The Hague, in the Pacific Islands.

This week, we look inside that extraordinary campaign, and hear the story of Cynthia Houniuhi, who - as a young law student from the Solomon Islands - helped launch the movement that would ultimately unite over 130 countries behind a single goal. Now, six years after this idea began in a law classroom, the world’s highest court is set to weigh in on the responsibility of states to protect current and future generations from climate harm.

Christiana Figueres, Tom Rivett-Carnac, and Paul Dickinson reflect on the power of legal activism, the role of youth leadership, and what this landmark case could mean for the future of international climate law.
