The Story of CO2 Is the Story of Everything

In short, it is the most important substance on Earth. But how is it that CO2 is as essential to life on Earth as it is capable of destroying it? In The Story of CO2 Is the Story of Everything, award- winning science journalist Peter Brannen reveals how carbon dioxide’s movement through rocks, air, water, and life has kept our planet’s climate livable, its air breathable, and its oceans hospitable to complex life. Starting at the dawn of life almost 4 billion years ago, and working all the way up through today’s global climate crisis and beyond, he illuminates how CO2 has been responsible for the planet’s many deaths and rebirths, for shaping the evolution of life, and for the development of modern human society. And he argues that it’s only by reckoning with this planetary-scale history that we can understand the cosmic stakes of our current moment on Earth—and how dangerous our experiment with the climate really is. Drawing on groundbreaking research and with a clear- eyed perspective, Brannen shows how a deep exploration of the carbon cycle can shed light on the way forward for humanity as we try to avert environmental catastrophe in the future. And it all begins with a richer understanding of the critical role of CO2 in our world.
