The Story of CO2 is the Story of Everything

A Planetary Experiment





An epic biography of the molecule that made – and could now break – everything we know

All life is made from CO2 . It was there at earth’s birth, and throughout evolution. It has kept our planet habitable for hundreds of millions of years. It has given us all the splendours of the world we know today. And yet it also holds the potential for life's destruction.

In this gripping adventure through eras and places, award-winning science journalist Peter Brannen tells the story of the world’s most important molecule. We travel from the beginning of time all the way up to our present reality, witnessing the staggering journey that CO2 has undertaken.

As we watch its movements through the rocks, the air, the oceans and living beings over four billion years, we come to see more clearly what it means for us to be churning through ancient life – in the form of fossil fuels – as we power our industrial world. We are, Brannen shows, performing an unprecedented experiment on our planet. If we are to avoid its catastrophic consequences, we must all begin to deepen our understanding of this curious substance, which has given us everything from the very first life forms on earth to the business titans reshaping our planet today.

Praise for The Story of CO2 is the Story of Everything

In The Story of CO2 Is the Story of Everything, Peter Brannen delivers a moving and magisterial tribute to the magic-seeming chemical interplay of air and rock, plant kingdom and ocean expanse, which scientists dryly call the 'carbon cycle.' Upon it, he shows, absolutely all life rests—with growing, and unnerving, precarity

David Wallace-Wells, author of The Uninhabitable Earth

Peter Brannen is spot on: Everything about life, our Earth, and our history is dictated by carbon, and even if we deny it, our future will hinge on carbon too. As climate changes so quickly around us, it is essential that we understand the power of this humble element, both in giving life and taking it away. In this urgent and astounding book, Brannen weaves together the entire history of Earth, and the origins and tribulations of life over billions of years, with the predicament we find ourselves in today. With the lyricism of John McPhee and scientific bona fides rivalling any academic geologist, Brannen is in a class of his own as the preeminent scribe of Earth science today. This is the book that I want all of my earth science students to read, and every policymaker and politician too

Steve Brusatte, University of Edinburgh paleontologist and New York Times/Sunday Times bestselling author of The Rise and Fall of the Dinosaurs

What a brilliant and epic book this is! From the magical transformation of CO2 into the first life to our current flailing attempts to pump less of it into our atmosphere, Brannen gives us a sweeping history of the planet in a single molecule. I study this stuff for a living and still learned so much—how coal nearly froze the planet, why the rocks beneath our feet allow us to breathe, and the origins of our modern industrial world. This book is a collection of wonderful things woven together into a fascinating, terrifying whole

Kate Marvel, PhD, climate scientist and author of All We Can Save and Human Nature

As with everything Peter Brannen writes, this is fascinating; deep history brought vividly to life. But it's also crucial--our ability to understand and act on it will determine how the next period in earth's history unfolds

Bill McKibben, author Here Comes the Sun

Peter Brannen offers a completely new vision of Earth and human history that will change your perspective forever. One vital, misunderstood molecule is revealed as the animating force behind everything that has ever happened on this planet—from the assembly of microscopic plankton seashells to the rise and fall of human empires. If we are smart, this impressive, beautifully written book will be a lodestar for the current generation’s most important decisions
