Book review – On Gaia: A Critical Investigation of the Relationship between Life and Earth

10-minute read
keywords: earth sciences, ecology

The scientist, environmentalist, and futurist James Lovelock is probably best remembered for the Gaia hypothesis: the notion that the Earth is a giant self-regulating system that maintains conditions suitable for life on the planet. It has gained a certain respectability in academic circles over the decades, but how justified is this? In my previous reviews of Lovelock’s original 1979 book Gaia: A New Look at Life on Earth and the 1995 follow-up The Ages of Gaia, I was critical of various assumptions and claims expressed therein. At the same time, I am aware that other, more knowledgeable people have worked on this idea for years, so what do I know? In On Gaia, Earth system scientist Toby Tyrrell gives a thorough and dispassionate overview of the scientific evidence and whether it supports Gaia. This, then, is the third of a four-part review series that explores the Gaia hypothesis in greater detail (see also part 1, part 2, and part 4).

Book review – Gaia: A New Look at Life on Earth

One year ago today, the famous scientist, environmentalist, and futurist James Lovelock passed away at the age of 103. Amongst his many achievements, he is best known for formulating the Gaia hypothesis: the notion that the Earth is a giant self-regulating system that maintains conditions suitable for life on the planet. I have always been somewhat suspicious of this idea but have simply never gotten around to properly reading up on it. High time to inform myself better and substantiate my so-far thinly-held opinion. Join me for a four-part series of book reviews in which I delve into Lovelock’s classic Gaia; his follow-up The Ages of Gaia; Toby Tyrrell’s critical investigation of its scientific underpinnings, On Gaia; and Michael Ruse’s wider analysis of its reception and historical antecedents, The Gaia Hypothesis.

Book review – Hurricane Lizards and Plastic Squid: How the Natural World is Adapting to Climate Change

7-minute read
keywords: climate change, ecology, popular science

If you had asked me last week how animals and plants will respond to climate change, I probably would have told you that they are expected to move towards the poles, shifting their home ranges as temperatures rise. This is indeed one possible response, but the challenges and opportunities for organisms are far more diverse and unpredictable. Biologist Thor Hanson has previously written much-praised books on feathers, seeds, and bees. Here, he gives a well-structured and terribly interesting whistle-stop tour of the nascent field of climate change biology and some of the fascinating research that is underway.

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 – Ocean Worlds: The Story of Seas on Earth and Other Planets

7-minute read

Life most likely originated in the oceans, and it is to oceans that astronomers are looking to find life elsewhere in the universe. With the publication last year of Kevin Peter Hand’s Alien Oceans, I decided this was the right time to finally review Ocean Worlds, a book that I have been very keen to read ever since buying it some years ago. This, then, is the first of a two-part dive into the story of oceans on Earth and elsewhere.

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.
