CO2 Chronicles: A Compelling New Book Urging Action on Carbon Dioxide Narratives

A Shared Narrative₂: It’s Everything
Peter Brunnen (Allen Lane)

Carbon dioxide influences our perceptions. Emissions from power stations, vehicle exhausts, and the burning of natural habitats contribute to our planet’s increasing warmth. These realities are compelling lawmakers and decision-makers to confront climate change earnestly.

CO₂, comprised of one carbon atom bonded to two oxygen atoms, is essential for life on Earth. However, the escalating levels of CO₂ are now exacerbating global warming and threatening life itself. This contradiction is a central theme explored by Peter Brannen in A Shared Narrative₂: Planetary Experiments, a meticulously researched and persuasive read.

Brunnen, a science journalist known for his previous work on the extinction events of Earth’s history, now tackles a monumental task: elucidating the carbon cycle (CO₂) and its implications, a topic often overlooked in educational settings, while revealing the fascinating stories that span our planet’s history.

It’s easy to overlook the periodic table. It’s also simple to disengage readers with mundane discussions about air movement. Yet, Brunnen artfully revitalizes this narrative, emphasizing CO₂‘s significance for all living beings. He vividly depicts events from millions of years ago, like the “Snowball Earth,” and the 56 million-year phase when the planet was “held captive by ice,” compelling readers to visualize these extraordinary, yet unimaginable, realities.

We learn in school that wood consists of carbon. However, Brunnen expands on this, discussing elements such as “mushroom psychedelics, pepper spices, and coffee caffeine.” While many authors might stop there, Brunnen elaborates: Carbon exists in “your eyeball, bougainvillea petals… blue whale baleen, fat, and brain… your tub scum, lion’s mane.”

These rhetorical flourishes may risk overwhelming the reader, yet Brunnen delivers a cogent and artful case. The highest praise I can offer this book is that it frequently inspires a childlike awe—a feeling we often take for granted, much like the subjects that permeate our daily lives.

However, this isn’t merely a children’s book. In addition to the planet and its inhabitants, Brunnen draws on historical insights to urge immediate action, advocating for a transition away from fossil fuels.

His analysis draws careful parallels between our current CO₂ emissions and those that precipitated the last mass extinction, a theme he reiterates throughout his work, articulating a growing urgency as he approaches his conclusions. “We can’t escape this dilemma,” he asserts. He critiques the notion of carbon capture and storage as merely a stopgap, arguing that it serves only to mitigate our current lifestyle without addressing the root cause. “In summary, we’re in deep trouble,” he writes.

Assuming no actions are taken and trends continue, he warns that companies may only awaken to their environmental impact after it’s too late, likening such reactions to misguided efforts.

This prevailing attitude, he observes, is common in “some climate circles,” and demands correction. “Sticking to the current path will undoubtedly lead to severe climate disaster, and regardless of how successful changes may be, we must explore all options to avoid catastrophe,” he states.

Decision-makers aiming to steer society away from fossil fuels would benefit immensely from engaging with this book.
