Book review – When the Sahara Was Green: How Our Greatest Desert Came to Be

7-minute read
keywords: environmental history, geomorphology, paleoclimatology

When seeing the world through a deep-time lens, no landscape feature is permanent. The Sahara, for example, “only” came into existence some 7 million years ago. In that time, it has not always been the parched desert it is now but has been green and verdant numerous times, crisscrossed by rivers and home to hippos, turtles, fish and other animals and plants typical of wetter climes. In this book, retired earth scientist Martin Williams draws on a long lifetime of research and desert expeditions to give a very accessible introduction to the surprisingly complex geography of the Sahara, answering some very basic questions.

Book review – The Science of Middle-Earth: A New Understanding of Tolkien and His World

7-minute read

I will make no secret of my love of J.R.R. Tolkien’s works. Equally, I am always entertained by books looking at the science behind fictional worlds depicted in books, movies, and TV series. The Science of Middle Earth is a remarkable undertaking, with three editors bringing together contributions on a wide range of topics, from humanities such as sociology and philosophy, to natural sciences such as geomorphology, chemistry, and evolutionary biology. Tying it together are Arnaud Rafaelian’s beautiful drawings that immediately draw your attention. Both a serious appreciation of Tolkien’s world and an entertaining work of popular science, this book hit the sweet spot.

Book review – Rivers of Power: How a Natural Force Raised Kingdoms, Destroyed Civilizations, and Shapes Our World

“There is a vast, arterial power humming all around us, hiding in plain sight” (p. 320). With these words, geographer Laurence C. Smith concludes his engaging and impressive book on the environmental history of rivers. Touching on a multitude of topics, some of which I did not even know I cared about, I found my jaw dropping more than once.

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 – Eager: The Surprising, Secret Life of Beavers and Why They Matter

When you think beavers, you think dams creating a safe microcosm in which they can thrive. But the effect of such dams ripples out well beyond that. In Eager, environmental journalist Ben Goldfarb presents a serious, incisive book that shows just how important beavers and their dams are for biodiversity, ecosystem health, and hydrology. If humans are now said to be a geological force to be reckoned with, birthing the term Anthropocene, our persecution of beavers led to the loss of another geological force.
