Notes on T.W.E.D. – chapter 1
Monday, February 28th, 2011I’ve decided to write a bunch of notes on the books I read, right here on my blog. It’s important to note that whatever these notes contain, it’s nothing but notes. It might be reflections, it might be quotes, it might be right, it might be wrong. So, if you happen to read any of this, please do not take it too seriously. Then plan is to use these notes later, as the starting point for a book of mine. Now, after this initial warning, let me begin with my first comment on Stewart Brand’s book “Whole Earth Discipline” – “T.W.E.D” for short.
Scale, scope, stakes, speed
Climate change, urbanization and biotechnology are the three themes Brand thinks will dominate this century. He might be right. Further, he says that there are plenty of illusions about them, but that their true nature is knowable. He might be wrong. Being a hyper-skeptic, I cannot help doubting such a claim. Brand says he have to get discard ideology entirely and let pragmatism (“a practical way of thinking concerned with results rather than with theories and principles”) take its place. I tend to agree, but I think we need to let a vision of the world we want to live in steer our pragmatic decisions. Brand states – correctly – that “saving the planet” isn’t the challenge, Earth will be fine, it’s us, humans, who are in trouble. I agree. Then he says “but since we got ourselves into this fix, we should be able to get ourselves out.” I disagree, or I have my doubts. It’s like saying that a little boy who jumps in a rushing river, should be able to get himself out of there, simply because he choose to jump.
There’s no reason to think he will, or that he will not. Whether or not he gets himself out depends of his ability to swim, nothing else. Thinking that we can save ourselves, simply because we got ourselves into this mess is optimistic, but – unfortunately – not necessarily true. Time will tell. Like the boy in the rushing stream, the best we can do is do our best, and hope it will bring us ashore. But there are no guarantees.
The nature of the game
Brand refers to a book by Harvard archaeologist Steven LeBlanc, titled “Constant Battles (2003),” wherein the author tells how war is the norm, and peace is what – occasionally – breaks out. It has, according to LeBlanc, been like that ever since the times of hunter-gatherers, through agricultural times and until early complex civilizations. About a fourth of adult males routinely died during warfare. At least, that’s how to story, if we are to believe LeBlanc. The reason for the perpetual fights are a lack of resources, whenever our population size outstrips the carrying capacity of our natural environment.
From this perspective, one could say that everything that increase the carrying capacity is good (assuming we prefer peace over war), and that includes everything from agriculture, (some) technological breakthroughs and large-scale diebacks from plagues and other killer diseases. However, population quickly rises to the brim of the carrying capacity, and we’re back at business as usual: war.
This reminds me of my high school fling with chaos theory – just the name arouse me – chaos theory. Oh yeah. There is a term used in chaos theory; attractor. Certain recursive complex functions will, after a while, settle on the same number. This number is called an attractor. The results (x1, x2, x3… xn) might – more or less randomly – flicker up and down, all over the place, until suddenly it hits the attractor, where it will stay. If I remember correctly, the same kind of thing typically happens in a biological environment, like an aquarium.
If we add the same quantity of nutrients every day and measure the population size in the aquarium, sooner or later the population settles on a size in balance with the environment. The population might flicker up and down for a while until it settles. Let’s call the number it settles on the attractor value. Like the recursive complex functions mentioned above, it doesn’t matter what the initial value is, sooner or later we will arrive at the attractor value. Beginning with a handful of fish in the tank, or with a hundred, the system will settle on the attractor value. It’s simply the nature of the game, or the game of nature, if you like.
The game of nature
It seems like we, like goldfish, the long ago extinct dinosaurs, the not so long ago extinct jambato toad, and the poor numbers in the centrifuge of recursive equations, are inevitably playing the game of nature. It also seems like the game of nature - like I (admittedly) – have a thing for chaos theory and attractors. When we talk about goldfish, dinosaurs, jambato toads, and human beings, the attractor is what is also called the carrying capacity, and whenever the population size – for one reason or another – differs from the carrying capacity, the game of nature will play out in a way that brings the system back in balance. And like a casino is rigged in favor of the casino, so is nature rigged in favor of nature. When the dinosaur or the jambato toad played the roulette of life, they didn’t even know it, they didn’t even know they were walking around in a casino. Nor did they know the casino was rigged. The goldfish doesn’t know either. But we do, and that’s where we differ. And unlike Jerry, the compulsive gambler goldfish, we have a choice. We can choose to leave the rigged casino, we can refuse to play the game. So, while this game is set up to stabilize the size of the human population just around the carrying capacity, and make all of us keep playing – hoping to win another year of life – we can, with a conscious decision, stop playing and live a life of abstinence. However, this is easier said than done. First, we need to escape our ludomanic nature (our oddly luck based way of living), second, we need to all agree to leave Las Vegas.
Only in the last three decades the overall body count from warfare has dropped, so now only 3 percent of the world population die in combat. This seems to be a step in the right direction. From 25 percent down to 3 percent. I wonder what the warfare body count is for other species on Earth. How many chimps or chipmunks die fighting among themselves? More or less than 3 percent? In other words: How advanced are we really?
If climate change reduces the carrying capacity so maybe less than half the world population will be able to eat, it will be a battle royale and a huge-scale wars seems likely, huge-scale wars with weapons of mass destruction at the fingertips of the people in power – whoever they are? Riots are not unimaginable, neither are fights among neighbors in the no longer convenient convenience store. LeBlanc is, like Brand, an optimist. He thinks that we, for the first time, have an opportunity to live in long-term balance with nature, “a chance to break a million-year-old cycle of conflict and crisis.” He might be right that we have a chance, however I don’t think it’s the first time we have such a chance, and I don’t think the solution is the invention of renewable energy sources, but rather the invention – or reinvention – of human beings. Not in a sci-fi sense of the word, far from it. The solution seems, to me, to lie in the renewal of the core values and belief system that steer everyone of us. If we do not renew, or at least re-adjust our core values and belief systems, we will steer – or be steered – into a world, maybe pleasant for some, unpleasant for most.
Microwave oven or freezer world?
Brand mentions a report he and others wrote on request from the U.S. Secretary of Defense in 2003. It was titled “An Abrupt Climate Change Scenario and Its Implications for United States National Security”. Their scenario was inspired by the sudden 2.7 Celsius drop in temperature that took place 8,200 years ago – in less than a decade. Brand mentions a common explanation for this sudden temperature drop, an explanation that is said to also explain why the temperature abruptly dropped 15 Celsius, 12,700 years ago, and staying like that for a thousand years, during the Younger Dryas. The explanation given is that the Gulf Stream was slowed (or stopped) by an excess of fresh water in the North Atlantic – caused by global warming, and melting ice. The report Brand and co. wrote examined what would happen if the Arctic ice melting at the time would lead to a similar situation, with a suddenly cooler and dryer climate, with droughts and storms as a consequence – and Europe’s climate suddenly resembling that of Siberia.
It’s a nice tale, but I have my doubts about our ability to predict the future. My dabble with chaos theory and fractals have left me with a strong conviction that small changes in the starting conditions can alter later outcomes tremendously, especially in complex systems. And the Earth climate is certainly complex. So, just because melting ice cooled the climate abruptly 8,200 years ago doesn’t necessarily mean melting ice today will cool the climate. One or more other factors might be different now, so maybe the melting ice – combined with other factors – will lead to a radically different scenario, than the one we experienced 8,200 years ago, or during the Young Dryas. Please note, I’m not saying we will experience a radically different scenario this time, I’m only saying we might. It other words, I’m not saying the prediction based on the previous events are wrong, only that they might be worthless, in the sense that they are no more likely than a guess based on no data at all.
On a side note, please notice how it is said that global warming 8,200 and 12,700 years ago lead to a cooling of the climate. If the same happens again, we might have Siberian conditions in Europe, and not African, as some predict. The measures we take in the hope to prevent our planned extinction will be very different, depending on which of these – maybe equally likely scenario – we (choose to) subscribe to. If we choose to take steps to prepare for an African Europe, and we turn out to be right – which we will not know until the die has been rolled – all is good. If we are wrong, not so good. And visa versa. So, it’s quite obvious – to me – that placing our faith in one or the other “scientifically based guess” is like playing Russian roulette with half of the chambers filled with bullets. It’s a game I wouldn’t want to play. The solution is obvious: we need to prepare ourselves for our future, without knowing how it will be. We have to take measures that will be advantageous no matter what happens. We need to realize our own ignorance, our own lack of abilities, and we need to admit and accept them. We need to prepare without knowing what we are preparing for.
By the way, no one was burning fossil fuels before the Young Dryas, and still – some say – there was a global warming, that caused melting of the ice. So is our release of CO2 into the atmosphere really what causes the ice to melt now?
The plague, the… and the ….
I think it’s on page 18, Brand is saying something about the earlier periods where the temperature dropped significantly. He seems to be referring to someone else, I don’t remember his name. Anyhow, if Brand (or his source) is right, I have a question. But first let me explain what he says. He says that three times in the last couple of thousands of years there was a drop in temperature. In each and every case as a consequence of a wipe out of a large portion of human beings on the planet. First, around 300 to 600, if I remember correctly, the Roman’s suffered from a plague or something, and died. Later, around 1300-1400 plenty of Europeans died, also from disease. And later, I think from 1500 to 1750, many of the Native Americans were wiped out when they were infected with – to them – unknown diseases from the European settlers. In each of these three cases, the population decreased drastically, and as a consequence large areas of agricultural land was naturally overgrown by wild forest. The increase in forest led to a decrease in CO2 in the atmosphere, and the temperature dropped. This seems to be an indication that CO2 and temperature is related, one being a consequence of the other, and to Brand an argument why we need to do something to reduce the CO2 in the atmosphere. His solution is dense cities, nuclear power plants, transgenic crops, restored wildlands and geoengineering. And we might be able to decrease the atmospheric CO2 by his means, but why not do something that seems guaranteed to work: reduce the population – as happened before with good results. I’m not suggesting that we line people up and shot them, I’m simply suggesting we find a way to make sure people will get less than two children in average – and the problem might be solved, with little cost and little effort.
