The Gaia guy: how James Lovelock struggled to be taken seriously

Nowadays, the area of study called “earth systems science” uses many ideas originally championed by Lovelock, though people are still allergic to the name Gaia.

It’s all William Golding’s fault. It was the author of Lord of the Flies who long ago suggested to James Lovelock, one evening in the pub, that the scientist use the name “Gaia” for his new vision of our planet. A nice literary idea, to borrow the name of the Greek goddess of the earth. The problem was that, to other scientists, “Gaia theory” sounded immediately like hippie earth-mother nonsense. And so began Lovelock’s decades-long struggle to be taken seriously.

In his revised and reissued autobiography, Homage to Gaia, Lovelock recounts with joy and wit an extraordinary life as an entrepreneurial scientist, inventor and gadfly. He claims to be not quite sure why “Gaia” got everyone’s back up so much, yet he gives sufficient reason later on, when he mentions that his American publishers retitled one of his books Healing Gaia, thus ensuring it would go on shelves in the New Age section of bookstores. I suspect that if Lovelock had deployed his alternative term, “geophysiology”, from the start, he wouldn’t have had so much trouble getting his ideas accepted.

For accepted many of them now are. And “geophysiology” is a clearer umbrella term to describe what Lovelock means by Gaia. The guiding concept is that the earth and all the life on it constitute a self-regulating system, which keeps itself in homoeostasis like a human body does. (Lovelock’s own training was in medicine and chemistry.) He first had the idea while working at Nasa’s Jet Propulsion Laboratory in the 1960s. Thinking about how the first Mars landers might test that planet for life, Lovelock realised that the presence of life changes the atmosphere of a planet to one of chemical disequilibrium. “If there were life on Mars,” he explained, “it would be obliged to use the atmosphere as a source of its raw materials and a place to deposit its waste products, just as we do.” (Our “waste products” in this sense include the carbon dioxide we exhale.) Lovelock’s experiment was used in the Viking landers, and his kind of atmospheric analysis is now a basic tool of astronomers.

This was the seed of the fundamental Gaian idea: that life and the planet exist in a feedback relationship that keeps the whole system at optimal levels for the continuation of life. Lovelock does not think the earth is actually alive like a goddess, but he will defend it as a metaphor. (Arguably it’s less iniquitous than the metaphor of the “selfish gene”.) “The deepest error of modern biology,” he writes, “is the entrenched belief that organisms interact only with other organisms and merely adapt to their material environment. This is as wrong as believing that the people of a village interact with their neighbours but merely adapt to the material conditions of their cottages.”

Nowadays, the area of study called “earth systems science” uses many ideas originally championed by Lovelock, though people are still allergic to the name Gaia, and so he doesn’t get as much credit as he should. But this splendid iconoclast is no friend to the green movement, either. Environmentalism – he says in his fascinatingly provocative new book, A Rough Ride to the Future, which shows, among other things, that even as a nonagenarian (he turns 95 in July), he hasn’t lost any of his appetite for a fight – has become as dogmatic as religion.

Lovelock particularly despises the species guilt some greens force on us for allegedly “trashing” the planet; it does, when you think about it, sound rather original sin-ish, with the steam engine as the new forbidden fruit. He calls Greenpeace a “great and powerful negative feedback on all that enlightened technical progress stands for”, and despairs of the popular fear of radiation. He makes the strong point, for instance, that the global media obsession with the story of the Fukushima plant flooding (which killed no one) in effect ignored the 27,000 people who had actually died because of the Japanese tsunami. That Germany and Italy subsequently shut down all their nuclear reactors he describes with simple outrage as “a wicked act”.

One of the main questions A Rough Ride addresses is what to do about global warming. Lovelock is no stranger to atmospheric threat (it was he who detected the atmospheric build-up of CFCs that were tearing a hole in the ozone layer) or simplified mathematical models (his Daisyworld model is a beautiful demonstration of how organisms can keep their environment at conditions ideal for life, with no planning or interplanetary competition required). He accepts that uncomfortable warming is probably inevitable, especially given that even if we stopped emitting all greenhouse gases tomorrow there would already be decades of warming to come because of the lag in the global climate system. The question, then, is what to do about it.

Lovelock finds the prospect of covering England with wind turbines as “satanic” as Blake found their ancestors. Geo-engineering he reckons beyond our capability and stupid anyway. Why try to control the whole climate artificially when we could accelerate the movement of the world’s population into cities and just regulate the city climates? (Perhaps, he suggests intriguingly, we are evolving into “superorganisms”: just as some biologists suppose that an ant’s nest is an aggregate organism unto itself, so a city full of human beings is one superorganism, too.) Gaia – who is under no such existential threat from global warming: she is, as one of Lovelock’s collaborators once put it vividly, “a tough bitch” – will take care of the rest of the world outside.

That essentially is his message: we can’t stop global warming (just look at energy politics since the Kyoto Protocol), so we’d better adapt to it with nuclear power and
urban air-conditioning. Would it be so bad, he wonders, if more cities were like Singapore, which is 12° Celsius hotter than the global average but still a highly desirable place to live?

The other future threat Lovelock considers is the rise of the machines, as in the Terminator films. He argues that since the beginning of the Industrial Revolution, we have, by human selection, inflated the speed of evolution of our technical artefacts by a factor of about a million compared to the lackadaisical pace of natural selection. Should we be worried that intelligent computers will take over? No, he says breezily. Either we’ll merge with them in a kind of cyborg utopia, or they will be so amazing as the next stage of planetary evolution that we should feel happy to have ushered them into existence.

It’s unfair to accuse Gaia-style thinking of being misanthropic, yet it does imply a benignly disinterested view of humanity – maybe, after all, something like a goddess’s-eye view. We are interesting, like ants, but just one component of what is most important: the whole system. Among the best things one can then say for humanity is that we are the crucial organisms that will construct the electronic creatures that succeed us, and that will be able to survive for longer and so keep Gaia going as the sun grows inexorably hotter. In other words, rejoice! We are nothing less than the John the Baptist species for the glorious robot future.

The fisher bird that unites levity with strength

We think the planet's fish are rightfully ours. But the brown pelican is known to snatch fish from other birds in mid-air.

If ever there was a time when I was unaccountably happy, it was the day I first saw the Pacific. I had just started working at an office near San Jose and, three days in to my first week, a colleague drove me south and west on a back road that seemed to run for hours through dense stands of Douglas fir and redwood, not stopping till we were just shy of the coast, the firs giving way to wind-sculpted specimens of California cypress and Monterey pine.

Here we parked and walked the rest of the way, coming over a rise and finally gazing out over the water. The Pacific. The idea of it had been part of my mental furniture since childhood, though I didn’t really know why, and what I saw both confirmed and confounded the image I had of that great ocean. But the thing that struck me most, the true source of my unaccountable happiness, was a long flight of brown pelicans drifting along the waterline, just ten yards from the shore, more elegant than I could have imagined from having seen pictures and captive specimens in zoos. This is not surprising, as what makes the brown pelican so elegant is how it moves, whether diving from astonishing heights in pursuit of fish or, as on this first encounter, hastening slowly along a beach in groups of thirty or forty, head back, wings tipped up slightly, with an air of ease that would give the term “laid back” a whole new definition.

The brown pelican: it’s a slightly misleading name, as the predominant colour varies from cocoa-brown to near-grey, while the breast is white and the head is brushed with a pale citrus tone, rather like the gannet, to which it is related. The birds breed on rocky islands off the Central American coast and travel north to hunt. In recent years, concern has been voiced for the species’ long-term safety: first, because of an observable thinning of the eggs, probably caused by pesticides, and second because, as recently as 2014, there was an alarming and inexplicable drop in the birthrate, which some observers attributed to huge fish-kills caused by Fukushima.

On an everyday level, though, pelicans, like cormorants and other coastal dwellers, have to be protected from those among the human population who think that all the fish in the ocean are, by some God-given right, unaccountably ours.

But none of this was in my mind that day, as I stood on that white beach and watched as flight after flight of pelicans sailed by. Out over the water, the sun sparkled yet the sea was almost still, in some places, so the bodies of the passing birds reflected in the water whenever they dipped low in their flight. What did come to mind was a phrase from Marianne Moore’s poem about another member of the Pelecaniformes family – the “frigate pelican”, or frigate bird, which she describes as “uniting levity with strength”. It’s as good a description of grace as I know.

Yet grace takes many forms, from the absolute economy with which an old tango dancer clothes her unquenched passion at a Buenos Aires milonga to Jürgen Schult’s world-record discus throw at Neubrandenburg in 1986, and we have to learn from birds such
as the pelican what we mean by “levity”, and “strength”.

How else to do that, other than by closely observing how the natural world really operates, rather than how we think it does? Later, in her poem about the frigate bird (an accomplished flier and an even more accomplished thief, known to pluck fish from another bird’s grasp in mid-air), Moore extends that notion of levity: “Festina lente. Be gay/civilly? How so?” and adds a quote from the Bhagavadgita that, to my mind, gets to the heart of the matter: “If I do well I am blessed/whether any bless me or not . . .” The lesson we learn from the noble order of Pelecaniformes is exactly this: of the many prizes we may try for, grace transcends all.
