Peter Brannen is an award-winning science journalist and the author of The Story of CO₂ Is the Story of Everything — a mind-bending journey through deep time that reveals how a single molecule shaped life, climate, intelligence, and mass extinction.Carbon dioxide isn’t just a climate statistic. It’s the raw material of all biology, the original building block of your brain, and the molecule that has repeatedly rebooted life on Earth. Understanding it means rethinking everything from the origin of life to the future of civilization.Expect to learn how CO₂ helped spark the first cells at the bottom of ancient oceans, why hydrothermal vents may hold the key to alien life, how volcanoes rewrote evolution, the truth about the most catastrophic extinction in Earth’s history, how CO₂ shaped your metabolism, brain and the rise of humans, why mass extinctions can reboot evolution, why today’s climate experiment is unlike anything in the fossil record, why the planet has a natural thermostat — and how we’re breaking it, why life might be a universal process of energy dissipation, how the story of Earth challenges our ideas of uniqueness, and much moreTimestamps: 02:14 How CO₂ Became the Most Misunderstood Molecule on Earth07:31 Life as a Carbon-Fueled Energy Dissipation Machine12:45 The Origins of Life and the Vents That May Have Sparked It19:08 Why Mass Extinctions Keep Rewriting Life’s Blueprint26:27 CO₂ as Climate Stabilizer — Until It Isn’t35:40 What the Permian Extinction Tells Us About the Future42:55 Deep Time and the Psychology of Geological Thinking49:18 Why the Anthropocene Might Be a Cosmic Joke55:36 How Life Changes the Planet — And Gets Changed in Return01:04:02 The Story of CO₂ as the Story of Everything01:10:15 Is Earth’s Climate Crisis a Rehearsal of Past Catastrophes?01:15:49 Carbon, Consciousness, and Why We’re Here to Begin With01:22:06 What Would a Geologist See If They Dug Up 2024?01:27:31 Hope, Humility, and What Deep Time Teaches Us...Email for sponsorship enquiries: [email protected] ❤️ Subscribe to our main channel - https://www.youtube.com/@thegiantsshoulder?sub_confirmation=1💚 Follow on Spotify - https://open.spotify.com/show/5m3Gta5MtIYdk59pb2GJ7M?si=Ka2rAQv7TyqiC9wvGwERpA💜 Follow on Apple Podcasts - https://podcasts.apple.com/ie/podcast/the-giants-shoulder/id1752486249Download my FREE EBook 26 Neuroscience Books for 2026 HERE: https://thegiantsshoulder.com/
