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.
