Book review – The Journeys of Trees: A Story about Forests, People, and the Future

6-minute read

We tend to think of forests as static. Trees, after all, do not move. But that is a perspective foisted upon us by our limbed existence. Science reporter Zach St. George unmasks this illusion in plain terms: when trees die or new ones sprout, the forest has moved a bit. “The migration of a forest is just many trees sprouting in the same direction” (p. 2).

There is no shortage of books on trees, but this sounded like such an unusual take on the subject that I was utterly stoked when I learned of The Journeys of Trees. A journalist who delves into the palaeontological record to consider the slow-motion movement of forests over deep time? Get in here!

Book review – Tree Story: The History of the World Written in Rings

7-minute read

To figure out how old a tree is, all you have to do is count its rings, and some truly ancient trees grace the pages of this book. But, as tree-ring researcher Valerie Trouet shows, that is the least fascinating thing you can derive from wood. Revealing the inner workings of the academic field formally known as dendrochronology, Tree Story is an immersive jaunt through archaeology, palaeoclimatology, and environmental history. A beautifully written and designed book, it highlights the importance and usefulness of tree rings in reconstructing past climate and linking it to human history.

Book review – The Anthropocene as a Geological Time Unit: A Guide to the Scientific Evidence and Current Debate

7-minute read

Since it was coined in the year 2000 by Paul Crutzen and Eugene Stoermer, the term “Anthropocene” has taken the world by storm – pretty much in the same way as the phenomenon it describes. Humanity’s impact on the planet has become so all-encompassing that it warrants giving this period a new name. As a colloquial term that is all snazzy, but are we actually leaving a tangible trace in the rock record to signal a transition to a new period?

Book review – The Ice at the End of the World: An Epic Journey Into Greenland’s Buried Past and Our Perilous Future

6-minute read

Like Antarctica, Greenland is one of those places that exerts an irresistible pull on my imagination. As journalist, historian and The New York Times Magazine feature writer Jon Gertner makes clear in The Ice at the End of the World, I am not alone. This solidly researched reportage chronicles both the early explorers venturing onto Greenland’s ice sheet and shows the reasons it plays a starring role in research on climate change. Some books ought to come with a warning about how binge-read-worthy they are. This is one of them.

Book review – The Deep: The Hidden Wonders of Our Oceans and How We Can Protect Them

What does the deep ocean make you think of? An alien world right on our doorstep? The cradle of life? A global garbage dump? The lungs of the planet? Or the world’s most abused ecosystem? If I am to believe marine biologist Alex Rogers, the deep ocean is all of the above, and so much more. With three decades of research experience and scientific consultancy credits for the BBC series Blue Planet II under his belt, he knows what he is talking about and he knows how to talk about it. The Deep is an intensely captivating and urgent book that swings between wonder and horror.

Book review – Origins: How the Earth Made Us

Origins asks one question: how did the Earth make us? More accurately, like a six-year-old whose curiosity cannot be sated, there lies a series of recursive “why” questions at the heart of this book. Astrobiologist and science communicator Lewis Dartnell takes a big history look at human evolution and especially civilization, seeing how far down the explanatory rabbit hole he can go. Time and again, he grounds his answers in geology and geography. You would be forgiven for thinking this sounds like what Jared Diamond attempted more than two decades ago, but calling it Diamond-redux would not do it justice.

Book review – Carboniferous Giants and Mass Extinction: The Late Paleozoic Ice Age World

Not so long ago, the idea that giant reptiles once roamed the earth was novel, unbelievable to some, but their reign represents only one part of deep time. Go back further in time, to the Carboniferous (358.9 to 298.9 million years ago), and you will find a world of giants as bizarre and otherworldly as the dinosaurs must have once seemed to us. A world where clubmoss trees grew up to 50 metres tall, with scorpions as large as dogs and flying insects the size of seagulls. With Carboniferous Giants and Mass Extinction, palaeobiologist George McGhee, Jr. presents a scholarly but fascinating overview of the rise and fall of this lost world, and why it still matters to us.

Book review – Climate Change and the Health of Nations: Famines, Fevers, and the Fate of Populations

When a history book leaves you reeling, you know that it has done its job properly. Climate Change and the Health of Nations is a grand synthesis of environmental history, charting the fate of civilizations and the links between climatic changes and the health of people. It is also a book that almost wasn’t.

Book review – Timefulness: How Thinking Like a Geologist Can Help Save the World

At first blush, you might think this book is part of the ongoing craze of spiritual mindfulness books. But let me refrain from snarky comments. Geologist Marcia Bjornerud does indeed want to instil a sense of mindfulness about deep time, but one that is, pardon the pun, grounded in geology. In her opinion, most of us lack an awareness of durations of important chapters in our planet’s history and of rates of change of many natural processes. As a consequence, we fail to see just how rapidly we are altering our planet. In one of the first paragraphs she eloquently writes:

“Like inexperienced but overconfident drivers, we accelerate into landscapes and ecosystems with no sense of their long-established traffic patterns, and then react with surprise and indignation when we face the penalties for ignoring natural laws”.

And with that, she had me hooked.

Book review – Brave New Arctic: The Untold Story of the Melting North

You might think that with the constant presence of the subject of climate change in news stories there isn’t much left to tell. But just because a certain sense of climate-change-fatigue might have set in (which is worrying in itself), climate change has not stopped. In Brave New Arctic, geography professor Mark C. Serreze gives an eye-witness account of how the Arctic is rapidly changing, based on his more than 35 years of personal involvement. And as he shows, there certainly are stories left to tell.
