#106 The Story Of How CO₂ Created ALL Life, Intelligence and Consciousness

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 more
