If you spend enough time learning about climate change, you come to regard the molecule carbon dioxide—abbreivated to CO2—with fear and frustration. After all, the long accumulation of CO2 is behind roughly 75% of Earth’s warming. Leaving aside the fact that we’re the species that put all that CO2 in the air, we’re also not viewing the bigger picture. That bigger picture is the subject of today's guest's modestly titled new book, The Story of CO2 is the Story of Everything. Read on...

Don’t get the wrong idea: Story of CO2 is not a starry eyed greenwashing affair. If anything, the book is asking us to approach the subject with humility. The carbon cycle may be miraculous, and a driving part of why life emerged on Earth, but that doesn’t mean it’s unchangeable. In continuing to burn fossil fuels, we’re tampering with that system, and at an alarming rate. Insofar as we’re already witnessing some of the consequences, we also have no way of knowing the full regimen of changes that might be occurring across the Earth system. To that, Peter employs some of the same time travel he used in The Ends of the World—which we discussed in an earlier episode—taking us on a journey through deep time to understand how the story of CO2 really did become the story of everything—at least as we understand it on our one precious planet.
