David Beerling - Four Way Interview

David Beerling is the Sorby Professor of Natural Sciences, and Director of the Leverhulme Centre for Climate Change Mitigation at the University of Sheffield. His book The Emerald Planet (OUP, 2007) formed the basis of a major 3-part BBC TV series ‘How to Grow a Planet’. His latest title is Making Eden.

Why science?


I come from a non-academic background. None of my family, past or present, went to university, which may explain the following. In the final year of my degree in biological sciences at the University of Wales, Cardiff (around 1986), we all participated in a field course in mid-Wales, and I experienced an epiphany. I was undertaking a small research project on the population dynamics of bullheads (Cotus gobio), a common small freshwater fish, with a charismatic distinguished professor, and Fellow of the Royal Society in London. Under his guidance, I discovered the process of learning how nature works through the application of the scientific method. It was the most exciting thing I’d ever encountered and kept me awake at night. I realised without doubt that from then on, I wanted to pursue the scientific understanding of nature as a career: academia beckoned. 

Why this book?

At one level, the answer is straightforward. The story of how plants won the land and diversified to ‘green the continents’ is central to our own existence and the millions of diverse species of animals we are fortunate to share the planet with. Everybody loves plants. Why wouldn’t you want to write a book explaining how it happened? At another level, I thought there was a problem. There are coffee table books documenting the diverse floras of the world with wonderful photographs, and there are worthy textbooks giving you the standard treatment of how trees evolved from algae. But it seemed obvious to me that we lacked a popular science account of how fast-moving exciting scientific discoveries are contributing to a new and deeply satisfying picture. The puzzle that confounded botanists for nearly a century has been (largely) solved. Yet at the same time our diverse floras, the legacy of those distant evolutionary events, are under threat from humans and human-made climate change. In writing Making Eden, I tried to give the big picture covering these issues too.

What’s next?

Climate change is one of the gravest threats facing society. It is increasingly obvious that urgent and drastic phase-down of our carbon dioxide emissions from burning fossil fuels for energy will be insufficient to avoid seeding catastrophic climate change. We will also have to figure out cheap, effective, scalable strategies for removing carbon dioxide from the atmosphere with well-understood environmental and social consequences. I am the founder and Director of the Leverhulme Centre for Climate Change Mitigation, which aims to develop the science and social science for one such strategy involving biogeochemical improvement of agricultural lands with natural and artificial silicates. In other words, looking at how we can harness the activities of plants to make them part of the solution to carbon removal. This work builds on fundamental advances I made earlier in my career and the translation of knowledge in this way perhaps helps reassure the public that scientists are not navel gazing 24/7.

What’s exciting you at the moment?

For many reasons, you need a gigatonne scale industry (1 gigatonne is a billion tonnes) to address the carbon dioxide removal problem. The same is true of the urgent problem of rebuilding our rapidly disappearing top soils that underpin food security for billions of people. The FAO estimates our agricultural top soil might be gone in 70-80 years – how can this problem not be headline news? Apart from the fossil fuel industries (coal, oil and gas), the only industries on the gigatonne scale today are steel and concrete (i.e. producers of bulk silicate waste), and agriculture. Why not think creatively about how we can link these industries together to remove carbon dioxide from the atmosphere, rebuild soils, and increase food security? It seems to me this a grand challenge we can address with a decent prospect of success that also represents fundamental and exciting opportunity for building a more sustainable economy and reducing waste, especially in developing nations, such as China. Our centre is actively thinking about the feasibility of joining the dots in this way.

It's On You - Nick Chater and George Loewenstein *****

Going on the cover you might think this was a political polemic - and admittedly there's an element of that - but the reason it's so good is quite different. It shows how behavioural economics and social psychology have led us astray by putting the focus way too much on individuals. A particular target is the concept of nudges which (as described in Brainjacking ) have been hugely over-rated. But overall the key problem ties to another psychological concept: framing. Huge kudos to both Nick Chater and George Loewenstein - a behavioural scientist and an economics and psychology professor - for having the guts to take on the flaws in their own earlier work and that of colleagues, because they make clear just how limited and potentially dangerous is the belief that individuals changing their behaviour can solve large-scale problems. The main thesis of the book is that there are two ways to approach the major problems we face - an 'i-frame' where we focus on the individual ...

Introducing Artificial Intelligence – Henry Brighton & Howard Selina ****

It is almost impossible to rate these relentlessly hip books – they are pure marmite*. The huge  Introducing  … series (a vast range of books covering everything from Quantum Theory to Islam), previously known as …  for Beginners , puts across the message in a style that owes as much to Terry Gilliam and pop art as it does to popular science. Pretty well every page features large graphics with speech bubbles that are supposed to emphasise the point. Funnily,  Introducing Artificial Intelligence  is both a good and bad example of the series. Let’s get the bad bits out of the way first. The illustrators of these books are very variable, and I didn’t particularly like the pictures here. They did add something – the illustrations in these books always have a lot of information content, rather than being window dressing – but they seemed more detached from the text and rather lacking in the oomph the best versions have. The other real problem is that...

The Laws of Thought - Tom Griffiths *****

In giving us a history of attempts to explain our thinking abilities, Tom Griffiths demonstrates an excellent ability to pitch information just right for the informed general reader.  We begin with Aristotelian logic and the way Boole and others transformed it into a kind of arithmetic before a first introduction of computing and theories of language. Griffiths covers a surprising amount of ground - we don't just get, for instance, the obvious figures of Turing, von Neumann and Shannon, but the interaction between the computing pioneers and those concerned with trying to understand the way we think - for example in the work of Jerome Bruner, of whom I confess I'd never heard.  This would prove to be the case with a whole host of people who have made interesting contributions to the understanding of human thought processes. Sometimes their theories were contradictory - this isn't an easy field to successfully observe - but always they were interesting. But for me, at least, ...
