Book review – London Clay: Journeys in the Deep City

6-minute read
keywords: archeology, earth sciences, geography

We walk on layered history. The ground beneath our feet is shot through with traces of our past, some in plain sight, many buried and badly eroded. Writer and artist Tom Chivers will concur that nowhere is this more true than in cities. London Clay is the result of a decade of exploration on foot, tracing vanished rivers, lost islands, and geological strata hiding under the concrete bedlam of modern London. The city’s untidy edges, its brownfields and derelict buildings, the very lay of the land—in Chivers’s hands all of these become cracks through which the past oozes back in. An unlikely chimaera of nature writing and urban exploration, this lyrical book offers a fresh way of looking at the built environment.

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 – Disaster by Choice: How Our Actions Turn Natural Hazards into Catastrophes

6-minute read

There is no such thing as a natural disaster. This is the provocative statement that Professor of Disasters and Health Ilan Kelman makes with Disaster by Choice. The title pretty much sums it up: Earth can be a violent place alright, but our actions, or lack thereof, turn these hazards into catastrophes that cause unnecessary death, damage, and destruction. So, what are we to do?

Book review – An Atlas of Geographical Wonders: From Mountaintops to Riverbeds

6-minute read

The 19th century was, for Europe and the United States in particular, a time of exploration and scientific study. Large parts of the world were still little explored and poorly mapped. Concurrent with the production of improved maps and atlases, there was a craze for a unique kind of infographic that has long since fallen by the wayside: the comparative tableau, showing the world’s highest mountains and longest rivers. This lush coffee table book sifts through the David Rumsey Historical Map Collection, one of the most renowned collections of its kind, to give readers a glimpse into the development and history of these unique images.

Book review – Cold Rush: The Astonishing True Story of the New Quest for the Polar North

Cold Rush is one of those books that invites a facepalm and a groan of: “humans… sigh”. The Arctic turns out to be particularly sensitive to climate change – the extent of sea ice cover has been hitting record-lows in the last decade, polar bears are moving into new areas as their habitat disappears, Greenland’s glaciers are melting in record-tempo, and scientists are publicly worrying we will see the North Pole free of ice within decades. You would think that we would be concerned. Instead, the nations around the Arctic rub their hands in glee: “Look at all these business opportunities: new shipping routes, newly accessible oil, gas, and mineral reserves… oh boy, we are going to make so much money!”

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 – Underground: A Human History of the Worlds Beneath Our Feet

Underground spaces exert a strong pull on the imagination of most people, although for some this morphs into a fascination bordering on the obsessive. American author Will Hunt is one such person, part of a worldwide community of urban explorers who infiltrate into “the city’s obscure layers”. Though this encompasses more than underground spaces, they are a big part of it, and this book is Hunt’s story of how he fell in love with them. It is one of two big books published only five months apart on the subterranean realm, and I previously reviewed Robert Macfarlane’s Underland: A Deep Time Journey. Here I will turn my attention to Underground.

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 – Land Bridges: Ancient Environments, Plant Migrations, and New World Connections

Before plate tectonics became an accepted idea in geology, Lyell’s doctrine of uniformitarianism still ruled supreme (see my review of Cataclysms: A New Geology for the Twenty-First Century for a short introduction). A corollary was that the continents supposedly had always been where they are now. One observation scholars had to explain away was that the same fossils occur on both sides of the various oceans. Looking at maps, some people noticed the thin strip of land connecting North and South America and concluded that land bridges must have formed and sunk beneath the waves at just the right times in history to enable migrations (see Four Revolutions in the Earth Sciences: From Heresy to Truth for more details). As explained in The Tectonic Plates are Moving!, we know better nowadays. Nevertheless, the concept of land bridges is still alive and well today, and palaeobotanist Alan Graham here introduces five of them, exploring their effects on biogeography, climate, and human history.

Book review – Earth History and Palaeogeography

This book is an example of what happens when you go down rabbit holes. I have been reading several books on the subject of palaeontology and geology lately, and I know that the face of the earth has shifted over the hundreds of millions of years of deep history covered in these books. But where were all the continents at different times? Many will have seen the iconic maps of the supercontinent Pangaea. But I want to know more. What happened in between? And before? As Nield tells in Supercontinent: 10 Billion Years in the Life of Our Planet, Pangaea was only one of several such supercontinents in Earth’s history. But I want to know more still. Where exactly were the continents located? And how did they move? Several accessible books have provided snapshots of iconic moments, such as the formation of the Himalayas (Mike Searle’s Colliding Continents: A Geological Exploration of the Himalaya, Karakoram, & Tibet) or the disappearance of the Tethys ocean (Dorrik Stow’s Vanished Ocean: How Tethys Reshaped the World). But I want to know more! This technical reference work contains lots of fantastic palaeogeographical maps that answered all my questions.
