Is Geoengineering Evil ?

According to biologist and science-fiction author Peter Watts, the dumping of a hundred tons of iron sulphate into the ocean off the islands of Haida Gwaii is a double edge sword and it could be working.

And most of all, nobody really cares.

[...]Proximately, the gambit seems to have paid off: the resulting bloom covered ten thousand square kilometers and greatly exceeds the penny-ante impact of more “legitimate” experiments. Whether it will actually increase salmon yield remains an open question, but it seems a reasonable expectation; the project was inspired by a paper in Fisheries Oceanography which connected the dots between volcanic ash-fall, diatom blooms, and record salmon catches. As to the potential long-term carbon-sequestration impact, nobody knows.

In fact, not only does nobody know, nobody even seems to give a shit. They’re too busy pointing fingers. Discovery News regards Russ George, the entrepreneur behind the project, as a “Geoengineering nut“. David Suzuki decries the effort as “stupid”. Scientists and lawyers fill endless column inches with quotes about bad experimental design and the breaking of international treaties. The UN is gravely concerned, and has granted the Harper governmentan actual award (“The Dodo”) for its role in this fiasco; the Harper government, those champions of the environment, has in turn condemned the entire affair and is “investigating” (although their misgivings have been a bit muted by credible reports that they knew about the project in advance and did nothing to stop it, which makes them complicit).

For my part, I’m not going to argue those who point out that the project was poorly planned, that phytoplankton blooms are often toxic, and that even when they aren’t local eutrophication often leads to anoxic “dead zones”. (Iwill observe that some of these charges tend to cancel each other out: you can’t both buy into Jay Cullen’s complaint that strong eddy circulation compromises experimental design while at the same time worrying aboutAlyssa Danigelis‘s specter of neurotoxic dead zones.) I have no trouble believing that Russ George isn’t interested in anything other than turning a fast buck (although if there are laws on the book that make it illegal to profit from climate-mitigation research, you have to wonder if its author had ever spent more than two minutes observing human behavior).

In terms of environmental damage, however, I can’t help noticing that right around the corner from Haida Gwaii, the city of Victoria BC flushes the raw sewage of eighty thousand people directly into the ocean. I can’t help noticing a thousand-square kilometer dead zone off the Oregon coast, or the seventeen-thousand-square-kilometer dead zone in the Gulf of Mexico, or the continent-long daisy-chain of dead zones skipping merrily up the eastern seaboard. If I squint hard enough I can just barely keep myself from noticing the salmon farms along our coasts that not only generate their own local anoxic zones but which also spread disease, parasites, and bad genes to wild populations. (I trust I don’t have to remind you all of past and ongoing oil spills.) All of these impacts arise directly from human activity — and while few would claim to like any of these things, I find it curious that the one-time dumping of a load of nutrients into the open ocean would provoke such outrage while all these other, vastly more severe impacts get off with a shrug and a what-are-you-gonna-do?

The fact is, the Haida-Gwaii patch is vastly bigger than any similar project heretofore attempted. It’s way out intoHere There Be Dragons territory, and you know what? It’s a fucking data point.

Bad experimental design? Let me remind you of another badly-designed experiment: that time about a decade back when a bunch of religious fanatics ploughed into the World Trade Center to prove that their invisible sky fairy was tougher than ours. Those guys didn’t check their flight plans with the research community at all, but that didn’t stop the scientists from making some serious inroads into the impact of jet contrails on climate change. (Granted, that particular inroad turned out to be a dead end. That’s science for you.)

This is nature, damn it. It’s a complex metasystem, if you think it’s ever going to let you run a “controlled experiment” in the laboratory sense then I’ve got some voting machines in Ohio to sell you. If you make the perfect into the enemy of the potentially-adequate you’ll never stop running simulations, because there is no perfect. Meanwhile, outside the window, Nature’s rolling her own D20. One day she’s going to kick over that anthill you’ve been too chickenshit to poke at all this time, and then where you gonna be?

This plankton stuff is small potatoes anyway; you want something to get scared about, stop looking out to sea and look up instead. Climate change is hitting the poles and the tropics especially hard — and the tropics are just chock full of small poor countries already sinking, increasingly impatient as the so-called developedworld sits on its ass and mumbles oxymoronically about clean coal. I wouldn’t blame them in the least if they got tired of waiting and started their own stratospheric geoengineering program out of self-defense — and it would be kind of nice if we had a bit of real-world data on that front, too, before it happened.

Make as many caveats as you like. Be cautious in your extrapolations, by all means. Remember that correlation is not causation, keep alternative hypotheses firmly in mind, scrawl Nature Is Not A Petri Dish onto a piece of duct tape and stick it over the Far Side cartoons yellowing on the wall. Be Adaptive in your “Management”. But use the goddamned data you’ve got. Don’t piss and moan because someone without all your degrees, someone more interested in bucks than biology, went out and took the first step when you were too fucking timid. Do it better.

Forget the world at large; Russ George’s sins pale into insignificance even set next the city of Victoria. The difference is, we can learn from his.

We’ve already kicked the whole world off-balance. We’re running out of time to figure out which way it’s falling.

Whether one adheres to the concept of the Kardashev Scale of Civilizations or not, of which becoming a Class 1 depends on human beings being able to control all processes of the planet; environmental and energy-wise, it doesn’t matter because we already have started down that road according to Watts.

It depends on us now to balance out these forces before Nature itself will surely balance things out.

And leave us in the dust-bin of planetary history.

Geoengineering and the Evils of Conservation

Geoengineering: Is it possible?

Global Warming, whether one considers it caused primarily by humans, or as a natural process determined by cyclical solar activity, is potentially a huge problem for the human race regardless of its cause.

One possible cure for GW is geoengineering. What is geoengineering you ask?

Well, read this post from The New Yorker:

Late in the afternoon on April 2, 1991, Mt. Pinatubo, a  volcano on the Philippine island of Luzon, began to rumble with a series of the  powerful steam explosions that typically precede an eruption. Pinatubo had been  dormant for more than four centuries, and in the volcanological world the  mountain had become little more than a footnote. The tremors continued in a  steady crescendo for the next two months, until June 15th, when the mountain  exploded with enough force to expel molten lava at the speed of six hundred  miles an hour. The lava flooded a two-hundred-and-fifty-square-mile area,  requiring the evacuation of two hundred thousand people.

Within hours, the plume of gas and ash had penetrated the stratosphere,  eventually reaching an altitude of twenty-one miles. Three weeks later, an  aerosol cloud had encircled the earth, and it remained for nearly two years.  Twenty million metric tons of sulfur dioxide mixed with droplets of water,  creating a kind of gaseous mirror, which reflected solar rays back into the sky.  Throughout 1992 and 1993, the amount of sunlight that reached the surface of the  earth was reduced by more than ten per cent.

The heavy industrial activity of the previous hundred years had caused the  earth’s climate to warm by roughly three-quarters of a degree Celsius, helping  to make the twentieth century the hottest in at least a thousand years. The  eruption of Mt. Pinatubo, however, reduced global temperatures by nearly that  much in a single year. It also disrupted patterns of precipitation throughout  the planet. It is believed to have influenced events as varied as floods along  the Mississippi River in 1993 and, later that year, the drought that devastated  the African Sahel. Most people considered the eruption a calamity.

For geophysical scientists, though, Mt. Pinatubo provided the best model in  at least a century to help us understand what might happen if humans attempted  to ameliorate global warming by deliberately altering the climate of the earth.

For years, even to entertain the possibility of human intervention on such a  scale—geoengineering, as the practice is known—has been denounced as hubris.  Predicting long-term climatic behavior by using computer models has proved  difficult, and the notion of fiddling with the planet’s climate based on the  results generated by those models worries even scientists who are fully engaged  in the research. “There will be no easy victories, but at some point we are  going to have to take the facts seriously,’’ David Keith, a professor of  engineering and public policy at Harvard and one of geoengineering’s most  thoughtful supporters, told me. “Nonetheless,’’ he added, “it is hyperbolic to  say this, but no less true: when you start to reflect light away from the  planet, you can easily imagine a chain of events that would extinguish life on  earth.”

There is only one reason to consider deploying a scheme with even a tiny  chance of causing such a catastrophe: if the risks of not deploying it were  clearly higher. No one is yet prepared to make such a calculation, but  researchers are moving in that direction. To offer guidance, the  Intergovernmental Panel on Climate Change (I.P.C.C.) has developed a series of  scenarios on global warming. The cheeriest assessment predicts that by the end  of the century the earth’s average temperature will rise between 1.1 and 2.9  degrees Celsius. A more pessimistic projection envisages a rise of between 2.4  and 6.4 degrees—far higher than at any time in recorded history. (There are  nearly two degrees Fahrenheit in one degree Celsius. A rise of 2.4 to 6.4  degrees Celsius would equal 4.3 to 11.5 degrees Fahrenheit.) Until recently,  climate scientists believed that a six-degree rise, the effects of which would  be an undeniable disaster, was unlikely. But new data have changed the minds of  many. Late last year, Fatih Birol, the chief economist for the International  Energy Agency, said that current levels of consumption “put the world perfectly  on track for a six-degree Celsius rise in temperature. . . . Everybody, even  schoolchildren, knows this will have catastrophic implications for all of us.”

The human race might have no choice but to try geoengineering by the end of the 21st Century if the prognosis of a six degree Celsius rise in temperature holds true.

But if we are to become a true Kardashev Level One civilization, humans must have total control of the energy outputs of the planet.

And that includes the climate.
