Book review – A Wilder Time: Notes from a Geologist at the Edge of the Greenland Ice

I have only ever seen Greenland once while flying over it on my way to a conference in Alaska. But geologist William E. Glassley has spent several field seasons together with two fellow geologists working in this rugged landscape, uncovering its geological secrets. This slim volume describes their work, but more prominently, it is a rhapsodic tribute to Earth’s wild places and the transformative experience of finding yourself far away from civilisation. I had not heard of Bellevue Literary Press before, but they aim to publish books at the intersection of art and science, and I would argue this book fits the bill well.

Book review – The Spinning Magnet: The Force That Created the Modern World – and Could Destroy It

If you have used a compass, you will know our planet has a magnetic North and South pole. You might even be aware that the geographical and magnetic poles are not exactly in the same location. The magnetic poles have a tendency to wander with time. They can even swap places, and we have evidence of a long history of such geomagnetic reversals in the rock record. But how does this happen? And what would the consequences be if this happened today? Earth’s magnetic field offers protection against radiation from outer space, primarily from the sun, so if this field weakens or changes, what will happen to us and our electrical infrastructure? Join science journalist Alanna Mitchell as she explores this topic and delves into the history of electromagnetism.

Book review – Four Revolutions in the Earth Sciences: From Heresy to Truth

Try as we might, science is very much the work of human beings with all their foibles. As such, scientific advances aren’t always straightforward and can run into opposition within scientific circles when new ideas run counter to currently established ones. In Four Revolutions in the Earth Sciences, American geologist James Lawrence Powell demonstrates this by taking the reader through the history of four ideas in the earth sciences that initially weren’t accepted. This was a book I very much wanted to read.

Book review – Cataclysms: A New Geology for the Twenty-First Century

Was the asteroid impact that caused the extinction of the dinosaurs a one-off? Or are other mass extinctions in earth’s deep history perhaps also linked to impacts of extraterrestrial bodies? Many scientists are reluctant to accept this idea. In Cataclysms, Rampino argues that it is high time to cast off the spirit of Lyell that continues to haunt geological thinking and embrace a new era of catastrophism.

Book review – The Ends of the World: Volcanic Apocalypses, Lethal Oceans and Our Quest to Understand Earth’s Past Mass Extinctions

Aaaah… the Apocalypse. Who doesn’t love Hollywood’s favourite movie trope? The spectacle, the drama, and the foreboding knowledge that – oh, spoilers – everyone dies at the end. There has been no shortage of good eschatological writing in recent years. Some books to come to mind are Erwin’s imaginatively titled Extinction, Wignall’s recent The Worst of Times, or Alvarez’s T. rex and the Crater of Doom – those pesky dinosaurs remain a popular subject. Do we really need another popular science book about mass extinctions? Given the continued developments in our understanding, and given that you get not one, not two, but all five for the price of one, I’d say yes. As far as I can tell the last comparable book was Hallam & Wignall’s 1997 Mass Extinctions and their Aftermath, published by Oxford University Press, which was a more academic treatise. So, get your bucket of popcorn ready and roll on the Apocalypse!
