Engineering the earth’s climate is nothing new. Capitalists, in coalition with alien overlords from Andromeda, have been at it for years.

That is the backstory to John Carpenter’s 1988 sci-fi classic, They Live. An alien race colonises Earth. Disguised as humans they run the world, helped by accomplices among the native business community.

They manipulate the human drones through consumerism and subliminal injunctions: ‘Obey,’ ‘Marry and breed,’ and ‘Work!’ The dutiful masses produce, reproduce and consume, all for the benefit of the Andromedan/capitalist masters.

They Live is celebrated for its cartoonish representation of capitalist ideology: wear the special sunglasses and those ubiquitous injunctions are rendered visible.

But another plot thread is equally original. Andromedans require a hot, carbon-rich atmosphere. So they hacked ours, adapting it to their needs by constructing economic systems that rely on fossil fuels.

In this, They Live subverts the approach of so much “Fabian” sci-fi, with its engineer heroes wielding applied science for the betterment of the world. The Andromedans are malign terraformers, villainous geoengineers. And when they’ve exhausted this planet’s resources, they’ll set their locust eyes on the next.

The Holocene was Eden

Adding CO2 to the atmosphere as a form of “climate experiment”—the Andromedan mission, as it were—has been dated to 1663. Why that year? It marked the founding of the Royal Society. The Royal Society’s structure was modelled on a sci-fi/utopian novel, Francis Bacon’s New Atlantis, and its mission statement was taken from the Bible: to rebuild Eden.

The Society’s associates combed the world, assessing environmental risks and opportunities. They developed systematic meteorology, measured climates and their rates of change, and intervened to alter them. One of its founders, John Evelyn, advocated the deforestation of England’s temperate colonies—Ireland and North America—in order to make their “gloomy tracts” habitable.

He and his peers were at the centre of England’s colonial thrust, which generated unprecedentedly rapid and global ecological transformations. They carried new mentalities: the world belongs to the European bourgeoisie; natural resources are free gifts for capital; science and technology provide surefire methods of taming and controlling nature.

What Evelyn & company failed to realise was that Eden is the Holocene—those brief, lush, ten millennia in which the world’s climate was unusually stable and benign for Homo sapiens.

Far from creating a new paradise, the social revolution they were spearheading ushered in a new era, the Capitalocene. It guarantees that Eden will wither away, perhaps for ever.

Sulfurous schemes

In recent years the Royal Society has become the most prominent scientific organization encouraging governments to experiment with geoengineering. In 2011 it declared that planetary-scale engineering interventions could be “the only option” for tackling a climate emergency.

But geoengineering had entered the scene half a century earlier. Indeed, ever since governments were notified of the hazards of anthropogenic climate change, geoengineering was floated by generals and technocrats as a response.

Its first appearance was in 1965. US President Lyndon Johnson’s Science Advisory Committee issued a report that warned of the potentially harmful effects of fossil fuel emissions. Considered the first high-level government statement on global warming, the report raised the possibility of “deliberately bringing about countervailing climatic changes,” including by raising the Earth’s albedo.

The method was suggested nine years later by Soviet climatologist Mikhail Budyko. He proposed reversing global warming by burning sulfur in the stratosphere. And how might we do that? Call in the artillery! Blast a million tonnes of pulverized brimstone into the heavens.

This last was Lowell Wood’s proposal, to a NASA conference in Silicon Valley. Wood knew a thing or two about artillery. A former weapons designer at the Pentagon, he had worked on the Reagan-era Strategic Defense Initiative. His mentor, and fellow geoengineering pioneer, was Edward ‘Father of the H-bomb’ Teller. In his stated motivations, Teller lays bare the soul of the geoengineer. He was “pessimistic about human social capacities but optimistic about technology”.

Lacking any faith in humanity’s ability to reduce greenhouse gas emissions, he sought a technical fix that would require no radical political or economic change.

In promising a technofix, with no need for democratic engagement, geoengineering is music to the ears of authoritarians, magnates, and government agencies.

Alongside the Pentagon, Silicon Valley and the Royal Society, its boosters include the CIA and motley magnates, including Bill Gates, the co-founder of Skype, Niklas Zennström, and Richard Branson—who co-funded the Royal Society’s geoengineering programme.

The oil giants and tar sands tycoons are major backers, too. They have long seen carbon capture as a means of greenwashing “enhanced” oil extraction.

There is even talk of hooking geoengineering to carbon trading schemes. This was the plan of Planktos Inc., whose ocean fertilization experiments conjure up a dystopian future in which the global climate is manipulated for corporate profit.

Bombastic elitist bazooka projects backed by oligarchs and shot through with fetishistic and magical thinking—you’d think this would appeal to the Trump regime and you’d be right.

Since Trump entered the Oval Office, geoengineering boosters say the political climate for their agenda “has warmed.” Former Republican House Speaker and Trump confidant Newt Gingrich has hailed geoengineering for its “promise of addressing global warming concerns for just a few billion dollars a year.”

Gingrich was among the first senior political figures to publicly promote geoengineering, and helped launch a geoengineering unit at his think tank, American Economic Enterprise.

Seeds of war

The weaponization of weather has been a feature of warfare since 1947. Its heyday came during the US war on Vietnam. If major geoengineering projects go ahead, it will take another leap.

Their costs and benefits will be uneven. Attempts to reduce solar radiation in one region will likely have knock-on effects elsewhere, such as droughts and the devastation of crop yields.

Geoengineering raises questions of sovereignty. Who declares the climate emergency, who determines the geoengineering methods and locations, and how will other states react? Conflict is guaranteed.

A likely first-mover would be the US, whether through a state-backed entrepreneur or a government agency. A classic hegemonic stance would be adopted, with Washington presenting its acts as in the global interest while ensuring that the techniques chosen would favour its territories.

Let’s imagine the chosen method is ocean seeding. It leads to unforeseen consequences, shifting Arctic weather patterns which trigger savage droughts across Russia.

In response, Moscow considers torpedoing America’s ocean fertilization vessels but instead launches a cirrus cloud-seeding program.

It too brings devastating side-effects—to East Asian rice harvests. In its turn, Beijing pushes the button on sulphate-spraying, but this sends the monsoons haywire, imperilling the lives of hundreds of millions.

This trajectory, from geoengineering démarches to counter-geoengineering and international friction or conflagration, is far from implausible.

Crushing olivine

While the above scenario depicts the US as initiator, geoengineering boosters, such as Kim Stanley Robinson in ‘The Left’s Case For Geoengineering,’ envisage different actors.

“If a hundred million people die in a heat wave,” the sci-fi author argues, and the Indian government sprays sulphates into the stratosphere, “are we going to tell them they can’t?” In this we see a rhetorical occlusion.

Obscured is that geoengineers research is centred in the Global North, and China. Robinson also downplays or ignores the thunderous drawbacks of sulfur spraying.

It does nothing to reduce the CO2 build-up, or to mitigate its other consequences such as ocean acidification. And it must be permanent, or risk a ‘termination shock’ when switched off—whether by design, accident, or war. Robinson’s intervention follows a raft of pro-geoengineering articles in leftwing publications such as Jacobin and Grist.

In justification of schemes such as sulfur spraying, Jacobin editor Peter Frase argues that its origins should not deter the left. Geoengineering technologies are neutral. What matters is not the techniques but “how they are implemented, and by whom.” Sulfur’s associations with Lowell Wood and his satanic colleagues would, in a socialist system, be swiftly forgotten. Others have noted that in Frase’s essay his recourse to tropes from sci-fi novels and movies enables the “technological, ecological, or social feasibility” of his predictions to be passed over.

Similarly, in his Mars series, Robinson stages lengthy debates over terraforming, and he proposes that many challenges of geoengineering, “both technical and social,” are “much the same” as in the pages of his novels. But this is, at best, an exaggeration. Few of his fantastic scientists and terraforming projects would survive the leap from Martian fiction to material fact.

One can be a historical materialist novelist or philosopher with little knowledge of chalk, cheese or any empirical substance.

But materials cannot be ignored if, say, carbon sequestration is to be discussed effectively—and not as wishful thinking. If BECCS or charcoal-burying is your preferred technology, how much land will be appropriated, and whose? Will it result in a rise in emissions?

If CO2 is to be ‘scrubbed’ from thin air, will olivine be the elixir, or calcium oxide, or sodium hydroxide? How will it be produced? Out of rocks plucked from which mountains? pulverized and processed with energy from what sources? Scattered across which steppes?

In view of the colossal wattage required, what territories will be overlaid with solar panels and where will the aluminium and rare earths be extracted? Is the estimate of 0.55 kWh—at minimum!—to capture a single kilo of CO2 realistic?

Or do leftist geoengineering fans pray that, in a cunning of chemistry, the molecular forces that bind CO2 will weaken under a socialist order, easing its capture?

Corrupting the general intellect

Devotees of geoengineering accuse sceptics of a fear of ‘science,’ or of grand projects and decisive action. These charges are farcical.

It is geoengineering projects that are designed to avoid the grand and bold decisions based on proven science: to sequester carbon through afforestation, to ramp up renewable energy and agroecological farming, to weatherize buildings, forcefully regulate energy efficiency and materials use, reduce beef and dairy consumption, and re-engineer transport systems from aviation and cars to bicycles, public transport, and ride-sharing.

Scepticism towards geoengineering is itself scientific, not only in its critique of the techniques themselves and their propensity to backfire, but also in that it subjects science—as a social institution—to critical analysis.

The organisation of scientific knowledge (the ‘general intellect’) has become increasingly subsumed by big business, with all the corruption that entails. It is well-known that Big Oil and other vested interests manipulated the science of climate change. That they were found out has not given them pause. The same corporations that sponsored climate change denial are now lobbying for biochar (charcoal-burying).

We can go further. The geoengineering industry thrives on fetishistic thinking, in two related forms. One is the belief that the reigning social order, based on capital accumulation and profit maximization, is natural and unchallengeable. The other is technological fetishism, the endowing of technology with magical powers and the belief that it is neutral in relation to its uses and users, and not wrapped up in social relations, institutions and mentalités.

In the fetishist’s imagination, technology is a tool separable from society, a wand waved from on high by business and state elites. This holds for most of the kit in the geoengineers’ fantasy toolbox.

Highly unaccountable, it depends on hierarchically stratified expertise, the cult of the expert, and rigidly centralized decision-making.

political technology, geoengineering belongs to the institutional apparatus that is preventing effective climate action and reducing the urgency for structural change.

Against this, a politics capable of negotiating the rapids of environmental change will require democratic negotiation and collective action, with the exercise of “collective restraint where necessary” and mobilisation for “shared, sustainable abundance where possible.”

How these struggles play out in the coming decade will, given climate feedbacks and tipping points, powerfully affect human beings (if any exist) in half a million years.

Here the sci-fi imagination can be brought into play. Its sensibility of deep time. Of the geological scales of prehistory, in which the hydrocarbons were slowly compressed, and the swifter demolition of ‘Eden’ that their usage is causing, which will affect our descendants in 3018 or 30018.

If humans have not perished by then, how will they see us? Will they see that we overcame the Andromedans? That we found the sunglasses?


  • Nice sentiments, but an effective program to prevent catastrophic climate change should be based on science, especially climate science and the biogeochemistry of the carbon cycle. The latter takes the knowledges of Nature seriously.

  • Ge-oengineeing as currently envisaged springs from the same mindset that got us into the climate predicament in the first place. It is a mindset that does not accept the reality that we are a product of Nature NOT its overlord. Our only hope is to turn our minds to working with Nature as the senior partner in our collaboration. To do that effectively we need to understand Nature and the web age is a good place to start that process.

  • Correction to the following from my previous comment, I said “it [CO2 level in atmosphere) is now a bit over 400 ppm; it would continue to rise even with immediate shutdown of fossil fuel combustion and current modes of unsustainable agriculture because of release of the carbon pool in the ocean.” Incorrect! The atmospheric CO2 level would go down because of the continued ocean sink which would grow weaker as the climate temperature continues to rise because of the inertia of heat stored in the ocean. This assumes that the CO2 flux from already deforested land and other sinks reduced by land use such as destroyed wetlands would be smaller than the ocean sink. Nevertheless, negative C emission technology will still be imperative to bring the level down below 350 ppm and keep it there, this is a strong conclusion from climate scientists.

  • Kudos to Gareth Dale’s sharp critique of the geoengineering schemes. However, there is another approach, which is imperative to implement along with rapid and deep curbs on carbon and other GHG emissions and the rapid transition to 100% global wind/solar power supplies, it is sequestration of C from the atmosphere into the soil and crust, to bring and keep the CO2 level of the atmosphere below the safe limit of 350 ppm (it is now a bit over 400 ppm; it would continue to rise even with immediate shutdown of fossil fuel combustion and current modes of unsustainable agriculture because of release of the carbon pool in the ocean. Without negative carbon emissions humanity will face a climate hell future much worse than the horrors we now witness. The most promising C sequestration approach is a massive program for reacting carbon dioxide and water underground with mafic rock, basalt (a pilot project in Iceland. This is not the same as mining olivine, crushing it, spreading it on the land to weather. Promoting sequestration into the soil (e.g., agroecologies) will supplement this approach but cannot replace it because warming has already reduced the capacity of soil carbon storage. Success is contingent on radical changes in both the physical and political economies. See my article posted at; updated in our forthcoming book, (
