🔍 Episode Summary:What if Earth came with a dashboard warning light — and it just started flashing red?In this pivotal episode, Mark Lynas sits down with Johan Rockström, one of the world’s leading Earth system scientists and co-architect of the planetary boundaries framework — the closest thing we have to that planetary dashboard.Together, they retrace the origin story of one of the most important scientific ideas of our time: that there are nine critical systems holding Earth in a stable, livable state… and that we’ve already pushed several of them past their limits.From tipping points to nitrogen overshoot, and from nuclear war scenarios to political pushback, Johan offers a bracing but hopeful overview of where we stand — and what it will take to keep our only home within its safe operating space. This isn't just an academic discussion. It's a user's manual for the future of civilization.🧠 Topics Discussed:🌍 What the nine planetary boundaries are — and why they matter🧪 How Rockström and Will Steffen integrated Earth systems, tipping points, and Holocene stability into a new framework🌡️ Why climate is just one boundary — and not even the most urgent🧬 Why the framework avoids assumptions about human needs or technology📉 The accelerating collapse of planetary resilience🧭 The boundaries as a “safe operating space” — not a call for de-growth🧱 Why sustainability constraints can drive innovation and prosperity☣️ How nuclear war would break multiple boundaries at once📊 The objective, precautionary science behind the threshold levels🛑 Johan’s critique of the Breakthrough Institute’s pushback — and what’s changed since👨‍🏫 Guest Bio:Johan Rockström is Director of the Potsdam Institute for Climate Impact Research and Professor of Earth System Science at the University of Potsdam. He is a globally recognised expert in resilience, tipping points, and sustainability, and co-originated the planetary boundaries framework — a cornerstone of Earth system science used by scientists, policymakers, and businesses around the world.📚 Recommended Reading & Resources:Planetary Boundaries: Exploring the Safe Operating Space for Humanity (2009)Breaking Boundaries: The Science of Our Planet – Netflix & BookThe God Species – Mark Lynas (2011)Potsdam Institute for Climate Impact Research (PIK)Stockholm Resilience Centre – Planetary Boundaries PortalGlobal Commons Alliance – Earth Commission💬 Quote Highlights:“If you breach a boundary, you enter the danger zone. Cross too far, and you risk irreversible Earth system change.” — Johan Rockström“We don’t set boundaries based on what humans need — we set them based on what the planet can tolerate.” — Johan Rockström“The real tipping point is when Earth stops being our best friend — and starts amplifying the damage we’ve done.” — Johan Rockström“We’ve made no progress. Zero. Halfway through the decisive decade, the curves are still heading in the wrong direction.” — Johan Rockström“This isn’t about constraint vs growth — it’s about whether the playing field still exists for us to grow on.” — Mark Lynas🌐 About WePlanet:WePlanet is a global citizen and science movement promoting bold, science-based solutions for climate, nature, and human prosperity.
