Book review – Terrestrial Impact Structures: The TanDEM-X Atlas (2-Volume Set)

7-minute read

When Google Earth first launched in 2001, I, like many others, found myself poring over satellite imagery. Identifying familiar and unfamiliar landmarks always brought a certain thrill, and spotting craters was part of that. But to properly map impact structures, you need a better dataset. The stunningly produced Terrestrial Impact Structures is a large-format atlas that maps all currently accepted ones, plus some likely candidates, and makes for an instant must-have reference work for any geology or astronomy library.

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 – 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 – End Times: A Brief Guide to the End of the World

6-minute read

If the end of the world is something that keeps you up at night you might want to skip this book. Some might snigger at the “rogue robots” in the book’s subtitle, but End Times is a serious look at so-called existential risks. Former foreign correspondent, reporter, and editor with TIME magazine Bryan Walsh takes an unflinching look at the various disasters that could wipe out humanity, the people whose jobs it is to seriously think through catastrophic threats, and how, if at all, we can prepare ourselves.

Book review – Fire in the Sky: Cosmic Collisions, Killer Asteroids, and the Race to Defend Earth

6-minute read

Can you have too many books on the same topic? Not four months after the publication of Cosmic Impact in February 2019, which I reviewed earlier this year, Scribner books published Fire in the Sky in June. The former book was written by astrophysicist Andrew May, while Gordon L. Dillow is a newspaper reporter and war correspondent, coming at the subject from a different angle. Despite touching on many of the same events and topics, he provides a wealth of new information in what is a thoroughly researched work of popular science. But first, let’s go to Arizona and turn back our clocks some 50,000 years.

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 – Catching Stardust: Comets, Asteroids and the Birth of the Solar System

Asteroids and comets have a bad reputation. Looking back over the books I have reviewed, they usually come up in the context of impact and destruction. But there are other important reasons to study them and geologist and cosmochemist Natalie Starkey here steps up as their enthusiastic spokeswoman. Whether as frozen time capsules, possible vehicles dispersing the basic chemicals required for life, or even future mining quarries, Catching Stardust champions the importance of scientific research on these celestial objects.

Book review – Cosmic Impact: Understanding the Threat to Earth from Asteroids and Comets

The idea of an asteroid or comet impacting with planet Earth and causing a catastrophe for mankind has long been given a cold shoulder in scientific circles. But with the notion that the dinosaurs met their fate at the hand of a rather large space rock it does not seem so outlandish anymore. NASA has started monitoring near-earth objects, but is there really something we could do if one was heading our way? Astrophysicist and science writer Andrew May provides a delightful little primer on these questions with Cosmic Impact, injecting this oft-hyped topic with a healthy dose of realism.

Book review – The Dinosaurs Rediscovered: How a Scientific Revolution is Rewriting History

If you are interested in dinosaurs, the last two years have seen a slew of great books published, and there is more in the pipeline. The latest I am reviewing here is The Dinosaurs Rediscovered from the well-known British Professor of Vertebrate Palaeontology Michael J. Benton. With a huge number of possible topics you could write about, and an already saturated book market, Benton has set himself a very specific aim: to show how the science of palaeobiology has moved from a descriptive, speculative scientific discipline, to a hard, testable, rigorous one. In other words, given that palaeontologists nowadays regularly make some pretty amazing and precise claims about creatures long extinct, how, exactly, do they know that?

Book review – The Edge of Memory: Ancient Stories, Oral Tradition and the Post-Glacial World

When I read the brief for The Edge of Memory, my first thought was: “Really, Bloomsbury is publishing a book on flood geology?” This creationist take on geology tries to interpret geological features in accordance with the Biblical account of a worldwide flood described in Genesis. If you haven’t read your Bible verses today, don’t worry, if I say “Noah” and “ark”, you probably know which one I mean. My guess was close, but not quite on the ball. Patrick Nunn, a professor of Oceanic Geoscience, here argues that ancient stories and myths hold within them descriptions of geological catastrophes and climatic changes. Welcome to the obscure academic discipline of geomythology.
