Book review – Volcanotectonics: Understanding the Structure, Deformation and Dynamics of Volcanoes

7-minute read

We all have a pretty good idea of what a volcanic eruption looks like, but they are only the surface expression of a much larger and longer underground process that is hidden from view. The internal workings of a volcano, its plumbing if you will, are studied by the relatively new scientific discipline of volcanotectonics. Icelandic volcanologist Agust Gudmundsson has been researching and teaching this topic for two decades and here delivers the field’s first textbook. In preparation, I beefed up my knowledge base by first reviewing a introductory volcanology textbook, but it almost was not necessary – Volcanotectonics turned out to be exceptionally instructive and accessible.

Book review – Oceans of Kansas: A Natural History of the Western Interior Sea (Second Edition)

8-minute read

The deep past harbours many events, epochs, and places that are still a mystery to me. Case in point: once upon a time, North America was cut in half by an enormous ocean. Something I was only dimly aware of. Luckily, Indiana University Press’s flagship palaeontology series Life of the Past has just the book to remedy that. I may be three years late to the party, but this 2017 book provides all the details one could ask for, and then some.

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 Story of the Earth in 25 Rocks: Tales of Important Geological Puzzles and the People Who Solved Them

Judging by the title of this book, you might expect it to talk of 25 remarkable kinds of rocks and minerals. But in the preface, geologist and palaeontologist Donald R. Prothero makes clear that his book looks as much at famous outcrops and geological phenomena. Bringing together 25 readable and short chapters, he gives a wide-ranging tour through the history of geology, celebrating the many researchers who contributed to this discipline.

Book review – Underland: A Deep Time Journey

Shelter. Yield. Dispose.

These three tasks, so says nature writer Robert Macfarlane, signify our relationship with the world beneath our feet, both across time and across cultures. Underland is his lyrical exploration of underground spaces where people have sought shelter from warfare or hidden valuable treasures, are extracting minerals in mines or knowledge in research facilities, or are looking to dispose of waste. It is one of two big books published only five months apart on the subterranean realm, the other being Will Hunt’s Underground: A Human History of the Worlds Beneath Our Feet which I will be reviewing next. But first, Underland.

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 – King of the Dinosaur Hunters: The Life of John Bell Hatcher and the Discoveries that Shaped Paleontology

When I think of turn-of-the-20th-century palaeontology, names such as Othniel Charles Marsh and Edward Drinker Cope are the first to come to mind. Their infamous rivalry, known as the Bone Wars, relied heavily on field collectors who did the back-breaking labour of prospecting and quarrying for fossils. Most of these bone hunters are barely remembered, and John Bell Hatcher might very well have remained thus. This meticulous biography by American palaeontologist Lowell Dingus saves Hatcher from obscurity and documents both his hugely successful work as a bone hunter, as well as his later stellar but tragically short-lived career as a curator.

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.
