The day an asteroid slammed into the Yucatán Peninsula some 66 million years ago is a strong contender for “the worst day in history”. The K–Pg extinction ended the long evolutionary success story of the dinosaurs and a host of other creatures, and has lodged itself firmly in our collective imagination. But what happened next? The fact that a primate is tapping away at a keyboard writing this review gives you part of the answer. The rise of mammals was not a given, though, and the details have been hard to get by. Here, science writer Riley Black examines and imagines the aftermath of the extinction at various times post-impact. The Last Days of the Dinosaurs ends up being a fine piece of narrative non-fiction with thoughtful observations on the role of evolution in ecosystem recovery.
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.
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.
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.
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.
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.
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.
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!
