Outline for the first chapter of an unwritten book on approaches to disorder

May 9, 2019

Classical Chinese thought tended to treat the world as process rather than as fixed thing. Taosim, for example, constantly suggests that there are at least two orders: the flow of tao, and the order that humans create through effort. The second order can always be disrupted by the first, and by the unintended consequences of human effort.

Humans are themselves part of this flow of the world, and human conception which feeds into action is, in many ways, a distortion of the world, as the flow is not easily broken into discrete categories, or ‘things’. Therefore, taoists suggest that right action, either ecological or political, involves learning to live and work with the flow of tao moving with constant correction, towards an ‘acceptable’ or ‘close to desired’ result. The main technique is encapsulated in the idea of wu wei, often translated as ‘action without doing’ or ‘action without exertion’. It points to a gentle action, which allows the flow of reality to manifest itself without being blocked. It is sensitive to, and accepting of, what might appear to be disorder.

Taoist action does not have to be peaceable. Sun tzu in his Bīngfǎ (Art of War) suggests many ways of increasing disorder in the enemy, allowing their deliberations and actions to disrupt their own tao, while taking advantage of this process of disruption. Again the principle is to be guided by actions without exertion, deceive the enemy, and to take advantage of the situation as it arises.

While Confucius seems devoted to creating a rigorous order, the book usually given the title Doctrine of the Mean strongly implies that the best the sage can do is, by constant attention, create islands of order in the flow, through attention to ritual and the right behaviour and right speech for that situation. While Confucian thought, does not completely oppose violent imposition of order, the wise leader should primarily lead by example. The leader will be emulated, and if the leader is virtuous then the populace will tend that way. Imposition of general order is not the first step, but the last.

While it seems clear that Taoism is not suggesting the world is without order, Taoists imply that this is not a static order; it has patterns but they change, human’s cannot conceive correct order and human action easily disrupts the most powerful and stable flow. Classical Chinese thought suggests that working gently with the flow of reality with attention to the unintended consequences of our actions should be normal. It suggests that if disorder appears we are not working with the real flow of things, or we have mistaken ambitions. It implies real knowledge is tacit, rather than explicit, and comes from careful and attentive interaction with the world.

However, this rather obvious practice and understanding is not common in the contemporary world.

A good idea is not enough….

April 9, 2019

Thinking about the way that things could go wrong is useful when we start thinking ecologically in terms of systems and complexity; unsuspected connections and feedbacks, interaction of supposedly separate systems, and so on.

Linear thinking, with understood and simple causal connections, is helpful but its not always enough. In recognizing complexity, we can recognize that ‘things’ frequently get out of control.

So let us suppose we have a solution to a problem. This is a list to point us to what may happen, if we don’t think about it. The list is almost certainly incomplete.

“that something is a good idea is not enough…”

  • It can be feasible, but we don’t put enough energy into it to do it in time needed or avaiable.
  • It can be feasible but it’s much harder than we think.
  • It may be feasible and succeeds, but it does not do enough.
  • It may be feasible and succeeds, but disrupts other systems we think are not connected to it
  • It can be feasible but powerful people and institutions attempt to undermine its possibility, so we have a political problem as well as an ‘engineering’ problem.
  • It can be feasible but normally non-powerful people unite against it as it disturbs them, or they have not been consulted, or they face problems you are ignoring.
  • It may be feasible, but fighting for it distracts our attention from significant problems, either to do with it, or to do with the rest of the world. (As when fighting against climate change distracts us from other ecological challenges.)
  • It could be feasible if we knew about, or involved, other factors that we currently either don’t know or think are irrelevant.
  • It could be feasible but the way we are organising it’s implementation is not helpful or destructive to its aims.
  • It can be infeasible to begin with.
  • It may not be compatible with our expectations of what it will do.
  • It can have unintended effects which make the situation worse, but we don’t know about them until its deployed.
  • It can be successful at first and then fail.
  • It can succeed.
  • Questions about ‘nature’ and geological time

    April 6, 2019

    A friend responded to the last post on nature. I understood them to be essentially making three points:

    Point one: The division between human and nature is similar to the division between body and soul, essentially ficticious.

    Point two: As Humans are natural phenomena, everything they have done is natural. So nature is damaging itself.

    Point three: Any act has unforeseen consequences and the world exists in geological time, consequently we have no hope of a political solution to climate change or ecological degradation.

    This is my attempt to deal with these issues.

    Point 1: The idea of ‘nature’ is a human construct. Like Bateson and others I prefer to think of ecologies and systems. These ideas do challenge ideas of separation, but I’d also like to suggest that the conceptual differences between ‘mind and body’ and ‘human and nature’ are different. The degrees of separation and independence are not the same.

    Firstly, there is a non-human world which has, in many senses, little to do with me. I am not it, and it is not me. It has gone on for billions of years without me. It will go on, hopefully for more billions of years, without me. Currently, humans cannot survive without the non-human, and they have emerged out of it – yet once emerged, humans are no longer just a non-reflective part of the rest of the ecology. They are never the whole of the system, and could even be thought of as having a potential to differ from the rest of the system.

    However, my body and me do not exist separately in this sense. I can only learn and act with this body. If one dies the other dies. My body is not non-human. It is what makes me human. There is no sense of independence of one side from the other, unless you believe in immortal souls – and that is probably the basis of the idea of separation. There is nothing obvious in the idea of the two being potentially separate or independent.

    This takes us to point 2.

    Point 2: This potential to be different may not be unique to humans, but there are human constructions which would not exist without humans. Just as there are destructions of ecological systems which would not happen without humans.

    It seems to me, there is a problem with dismissing the term ‘nature’ and then keeping the word ‘natural’ to apply to everything which happens on earth and take a position in which human acts and decision become irrelevant, or perfectly in keeping with the rest of the eco-systems. Without this somewhat indiscriminate application of the idea of ‘natural’, there is a sense that humans are ‘extra’ to nature, despite emerging from nature.

    Paving a forest is not ‘natural’, as in the world without humans, or human equivalents, this could not occur. Again it emerges out of an ecology, but is destructive of the ecology in a way that the ecology could not achieve without humans. Humans are special, but they are not so special they are above nature. This seems hard for people in the west to grasp. People seem to want humans to be either above nature, or just another bacteria of no real consequence.

    To restate: while humans emerge from an ecology of ecologies, the consequences of their acts and decisions can be destructive to the rest of the ecology, and they can be aware of this. In that sense they can be contra-‘natural’ or contra-ecological. This is not a purely human phenomena, other organisms have changed the world’s ecology, but those organisms do not appear to have decided to do this, and have done it slowly enough for other life forms to evolve to deal with, and take advantage of, the transformation. The change has been ecological. Again this is not saying humans will destroy the world, eventually new life will arise, but possibly human life will not survive the rapid changes we are inducing in our ecology, and I personally would find that sad.

    Point 3: While it is true that many other creatures seem intelligent or self-aware, it also seems that humans are both intelligent and self-aware to an extent which is unusual. This does not mean that humans are intelligent or self-aware without limits, but it does mean that we have a greater degree of responsibility for our actions. If a bacteria developed which ate everything in its path, then we would probably try and defeat it, but we would not hold it morally culpable. If humans destroy everything in their path then, most humans in their path would say the destroyers should, and perhaps could, have made a different decision. Indeed it appears to be the case that humans, and many creatures, can make decisions.

    Finding the right time scale on which to live and make decisions, is likely to be vitally important for life in general. Some decisions or reactions have to be made immediately if you are to survive. Some decisions reflective creatures have more time to make, and for some decisions the creatures may need to think about the time frame for the effects of that decision, whether it is hours, days, months, years, centuries and so on. Thinking either in too long time frames or too short time frames can be deleterious to effectiveness.

    Looking at making political or ethical decisions within a time frame of geological time is a good way to achieve demotivation. This is probably why many of the people who embrace climate do-nothingness, or those few non worried scientists, appear to prefer thinking in geological time frames. In terms of geological time, human lives do not matter, creatural lives do not matter, even species survival does not matter. The rocks go on. Life goes on, and it is way outside our sphere of activity.

    Nothing matters so we don’t have to make decisions, we don’t have to struggle, we don’t have to worry, we do not have to take any responsibility for any of our own actions in geological times. We can, inadvertently, just let powerful people get on with destroying life chances for everyone, for their temporary benefit – because you can be sure the rulers of the world are not thinking in geological terms. Indeed it seems a common complaint that business does not think beyond the next quarter, which is probably too short a time frame for long term social survival, and increases the risks of any climate change….

    One thing that seems to happen regularly when people discover complexity theory, is the assertion that because you cannot control everything in fine detail, you cannot influence anything, or make any decision that is wiser or better than any other. As a consequence, some people argue that complexity theory is wrong, while others argue that politics is wrong. In both cases people seem to be saying that because we cannot do everything perfectly, we can do nothing. This seems silly, and we make decisions and act in our lives all the time despite the fact that these decisions don’t always have the expected consequences. Indeed, most of us might be bored if they did.

    It then seems strange to argue that human oppression of other humans is nothing new, and that some humans suffer disastrously because of this. This again seems an abdication, a demand for perfection of complete non-oppression, or a refusal to deal with difficulty. We may not remove hierarchies completely, but that does not mean that some hierarchies are not better than others, and we should not strive for better hierarchies. It also seems odd to tie this in with geological time, as in geological time, these kinds of destructive human hierarchies are extremely new. They are probably at most 10,000 years old, which is nothing.

    As a side note, it seems to me, that the so-called hierarchies found in ecological systems are not the same as hierarchies in human systems, it is just a metaphor being taken for reality; ecological hierarchies don’t deliberately oppress in an attempt to generate their own benefit.

    Humans are capable of living without mass destruction of global ecological systems, if they learn to adapt to systems or discover how change those systems in beneficial ways, that continue in human time frames. We know this. Some complex civilisations have lasted for considerable periods of time. This means that it is possible to live with ecologies. Difficult, but possible. It is partly a matter of choosing the right frameworks.

    Making all human behavior ‘natural’ and thinking in geological time frames are probably not the right frameworks.

    Sea level rise and Climate change

    March 31, 2019

    We all know the threat that coastal cities will likely be inundated by rising seas. Indeed in some parts of Australia, Local Councils are apparently declaring that some low lying residential areas are to be abandoned. Residents are, I’m told, even being forbidden from raising their houses higher or otherwise attempting to protect them. This is, in my opinion, crazy. It seems to be a way of trying to pretend that we should not act, or that everything will be ok.

    Other people point out that certain cities, such as New Orleans, or even countries such as Holland, are already beneath sea level, and its all ok. Of course in New Orleans this was one reason why Katrina was so disastrous. However, when things, like being beneath sea level are normal, and have been normal for a long time, they can be generally be dealt with, no question. Levee and dyke walls already exist and perhaps it will be feasible to expand them to cope with the extra pressure of more water.

    Some problems here stem from the nature of the cities themselves. Some cities are built on relatively porous rock, or even on sand (think of the Queensland Gold Coast) and, in that case, waters may flow under levy walls, and rise up to sea level. New sea walls are also likely to have to extend either for large distances inland or along the coast and change the coastal ecology and erosion patterns – although those will also be changed by climate change. Relatively close to the surface water tables could also be contaminated. It is complicated.

    Other people can argue that the current rate of sea level rise is so slow that we have nothing to worry about at all. For example we can quote the Royal society, the “best estimates of the global-average rise over the last two decades centred on 3.2 mm per year (0.12 inches per year).” At this rate it would take over 600 years to get a rise of 2 metres. We could probably deal with this quite easily.

    However, there are lots of problems with accurate prediction of such things as sea level rise.

    The first is that the rate of rise is not going to be linear. The more land ice melts, the less radiation reflected into space and the more land ice will melt. The more greenhouse gases we keep emitting then the faster the melting will happen, and if we reach the tipping points at which methane starts rising from the deep ocean and the tundras, then it could start happening very rapidly.

    People keep talking as if climate change and its problems expressed a nice gentle and smooth process, but it is not going to be that way. It is turbulent and chaotic. The climate system is what is known as “complex”, and turbulent change, once it is thrown out of equilibrium, is its nature. It will be hard to deal with, once things really start shifting, and they could shift rapidly.

    That is why we need to act now while the situation is not too bad. That is why we keep being told that we have to reach greenhouse gas targets by 2030, and that it is better to come in even lower. If we don’t reach those targets then the probability of great turbulence is very high.

    Anyone who tells you there is nothing to worry about, is assuming that they can predict a nice transition or control that transition. This position is extremely unlikely.

    It is best to agitate for action to reduce greenhouse gas emissions and reduce the possibility of chaos, now.

    Further reflections on energy and entropy in economics – Jancovici again

    February 25, 2019

    In the previous post, I suggested that Jean-Marc Jancovici insists that economists ignore problems of energy availability, and this distorts their (and our) economic expectations.

    As previously implied, we can add that life and economics exist on this planet because of the slow self-destruction of our Sun. If the Sun emitted too much radiation (or the planet received too much radiation) it is doubtful that sophisticated life could exist anywhere on the planet – although possibly some life could survive deep underground or near vents in the deep oceans. If we received too little radiation, life might be similarly constrained. Eventually in the far distant future the sun will die, but this is way too far in the future for us to bother about at the moment.

    In this sense solar energy is fundamental to life and society. Manual labour (the basis of many economic theories) and human thought, experiment or design only exist because of the energy humans and creatures extract from food, and that ultimately depends upon the Sun’s radiation and self-destruction. Energy from the sun is stored by, amongst other things, coal and oil, and is released in fire.

    As we know, forms of organisation can massively magnify the power of human thought and labour (and massively disorganise them, or waste then, as well). Putting these points together, Jancovici’s argument declares that the energy we can extract through the ways we organise burning fossil fuels massively overshadows the power of human labour in creating social ‘value’ and material goods.

    To restate:
    Energy consumption and its organisation and implementation through social organisations and other technologies (the social aspects) is fundamental for the kind of economies we have today.

    We should note that we also adapt our economies to the kinds of availabilities of energy that we have to deal with. Power is currently cheap at night because coal fueled electricity has not been ‘dispatchable,’ or particularly variable, and much energy is wasted.

    Changes in energy supply and availability will have economic and organisational consequences, and we currently need to change energy supplies because an unintended consequence of fossil fuel based energy supplies is climate change. There are other forms of ecological destruction happening which are as important, and which reinforce climate change, but I’m currently putting them to onside – not, I hope, ignoring them. The prime cause of climate change reintroduces the importance of entropy.

    Entropy is one of those scientific concepts over which there seems a fair bit of dispute, and a relative ease of misunderstanding. I’m warning any readers that this may be all be wrong. Please let me know if you know better. ‘Entropy’ is a description of a process, rather than a thing, so it is possibly better to talk about ‘entropic processes’ rather than ‘entropy’. The point of entropy is that any use of energy, any ‘work,’ engages entropic processes alongside that usage. These entropic processes are usually dissipated as heat (random molecular movement) and/or through reduction of what appears to be constructive order or demarcation.

    It is often postulated that entropic processes will lead to “universal heat death.” This is a state in which there is no more energy in one part of the universe than in another. Particles are completely randomly distributed. Whether this state is a state of total order or total disorder is up to you – the paradox is obvious and implies life is a ‘mess’ (or ‘balance’ if you prefer) of order and disorder.

    At the extreme, this idea also implies that too much work will generate too many entropic processes and the planet will warm independently of what precautions we take. The use of air-conditioners in some Cities is supposed to increase the heat of those cities (as the heat involved in producing the cooling dissipates outside the area of cooling), and thus encourages more air-conditioning and more heating. The same may be true of automobiles (engines moving people around get hot, and dissipate that heat). An economy necessarily produces (semi-organized forms of?) dissipated heat.

    We all hope that this extreme fate is ultimately avoidable or far off, or avoidable because we have spare energy to do something about it. We could develop more efficient engines or ways of cooling, or better ways of organising those processes (but this can never stop excess heat being dissipated). Ordering processes can always create disordering processes – and we should not ignore the disordering, or entropic, processes simply because we like, or are impressed by, the order. What we define as order and disorder come together. Another problem here is that the more complex the processes we use to prevent the entropy we generate from overwhelming our order, then the more energy the order may take to keep going, and the more prone the system may be to accident or collapse.

    Entropy also suggests that, while we use energy to produce useful transformations, we also produce waste or pollution by breaking things down. This is furthered by forms of social organisation which make it acceptable to create waste, or allow waste and poisons to be allocated to ‘unimportant’ areas, and onto relatively powerless people, where the effects can be ignored. If you like, blockage of information (in this case about pollution) is as important a part of current economic life as is accurate and resolvable transmission of information.

    Just as wealth gets allocated by patterns and processes of ‘social class’, so does waste, probably in an inverse form; waste and risk of harm gets distributed away from wealth. However, as waste tends to randomness, this distribution may not be quite as rigorous. Few will totally escape climate change.

    So we may say that the implications of Jancovici’s argument suggests orthodox economists not only ignore the availability and organisation of energy as important to economy (other than as labour), they also ignore entropic processes and waste and their forms of organisation and disorganistion.

    It therefore appears we need a new orthodox economics which deal with these things. So part of the next stage is to look at some criticisms of Jancovici and the work that has been done to factor energy and entropy into economics.

    To restate, yet again:

    Energy availability, its capacities, organisation, distribution, implementation and consumption through social organisations and other technologies, and the effects (both intended and unintended, such as entropy waste and pollutions etc) of its production and organisation (etc.) is fundamental for understanding the kind of economies we have today.

    Energy cannot be ignored

    IPCC, complexity and climate

    February 8, 2019

    There seems to be a meme going around that the IPCC disproved climate change in one sentence and removed that sentence from reports. The sentence is:

    “The climate system is a coupled non-linear chaotic system, and therefore the long-term prediction of future exact climate states is not possible.”

    The sentence is found in the “Climate Change 2001: Synthesis Report” edited by Robert T. Watson and the ‘Core Writing Team’, Published by Cambridge University Press, and recently available on the IPCC website.
    here https://www.ipcc.ch/site/assets/uploads/2018/05/SYR_TAR_full_report.pdf

    (The IPCC website is being reorganized and hence stuff can be difficult to find – google does not appear to have caught up yet)

    It is in the Technical Summary Section, p.58. or page 215 of the full report
    According to Archive.org the text version of this was available between at least August 4 2009 until at least November 4 2018.

    There is no particular evidence that they hid this sentence.

    The sentence is included on a section entitled “Advancing Understanding” and is about further research into uncertainties. It is prefixed by the requirement that we need to “Explore more fully the probabilistic character of future climate states by developing multiple ensembles of model calculations.” I’d add that, it seems nowadays more generally realized that we cannot understand ecological, climate and social systems without an understanding of complexity theory.

    By my understandings of complex systems, this apparently unsuppressed sentence is entirely true: we cannot predict exact weather, or climate states, within any accuracy in the relatively distant future for a particular date or year. That is the nature of complex systems. However that does not mean we cannot predict trends, or that any result at all is possible.

    The sentence is not embarrassing, or disproving of climate science, it is, however, easily misunderstood.

    People do not understand the limits on chaos and complexity. Because we cannot predict exactly what will happen does not mean that anything can happen, or that any predictable event has equal probability, which is what ‘deniers’ seem to argue.

    It is, for example, if you will pardon the political implications, possible, but exceedingly improbable that President Trump will stop making things up, and everyone will agree that he is constantly telling the truth – at least I cannot predict the exact circumstances under which this would happen, and when it will happen. It is not an impossible event, but it is highly improbable based on the trends. Similarly, because I do not know where an ant will be on a moated table top in exactly quarter of an hour (assuming I have not placed some kind of sticky substance on the table on one spot etc.), does not mean it will start flying, or that it will talk to me. It is, likewise, extremely improbable that despite lack of certainty, and assuming weather stays stable, that it will snow in Sydney Australia in January or February.

    The point is that the inability to predict an exact climate or weather state, does not mean we cannot make informed predictions based on the trends, provided we correct for further information as it arises.

    The trends so far suggest, and seem confirmed by observation, that sea ice and land ice is thinning near the poles. Likewise glaciers seem to have been getting smaller over the last 30 years. There is no indication that these trends are reversing, and some that they are speeding up. The rate of disappearance appeared to slow down for a while, but it continued and never reversed. This in all probability means that sea levels will increase – it may mean water shortages in some places that depend on glaciation for water supply.

    It is possible that as the gulf stream shuts down, some parts of Northern Europe (especially the UK) will freeze up and ice will accumulate there. But this probably will not help that much, and is no evidence that climate change is not happening or not going to have disruptive effects.

    Similarly, if the average temperature keeps increasing elsewhere then weather patterns will be disrupted. Disruptions of the standard patterns of complex systems are nearly always fierce as the system ‘seeks’ a new equilibrium. This is especially so, if the pressures towards change continue or increase (ie if we keep emitting greenhouse gasses). It is a good prediction that we can expect more extreme weather (which is what we seem to be observing). We cannot pinpoint exactly when and where that weather will happen, but it would be foolish to pretend that this pattern is extremely unlikely to happen anywhere, or that it will discontinue in the near future. We can also expect it to become increasingly difficult to get insurance, or to find the money to rebuild cities wrecked by these storms.

    Likewise increased heat in places which are already difficult for agriculture or prolonged human labour, will probably mean that these areas become increasingly uninhabitable and production will be lowered. If people try to air condition fields with fossil fuel power (or something), that will in the long term increase pressures. This trend probably means population movements as people try to move somewhere more habitable with better food supplies. That probably means national boundary defense issues will increase. Again there is nothing, at present, to suggest that these currently existing trends will not continue.

    To encapsulate: While we cannot predict exact events, the trends are clear. If we keep emitting greenhouse gasses then the global average temperature will continue to rise. What we consider normal climate/weather will end. Sea levels will rise. Extreme weather events will become more frequent as the climate system destabilizes – the cost of repairing devastated cities may become prohibitive because there are so many crises happening simultaneously. Agricultural systems are highly likely to break down. People movement will intensify as people can no longer live in the areas they have lived recently. This may mean increased armed conflict, which is one reason why the Pentagon would be interested in climate change.

    This does not mean that people should not struggle to change the trends and therefore change the likely course of climate disruption, but those actions are likely to have unintended consequences (which are almost inevitable in complex systems), and we need to be aware of this.

    However there is almost no sign of such action happening, as people would rather pretend the unlikely is equally probable to the disastrous.

    Complexity and social life again

    January 5, 2019

    Another attempt to summarise the relations between complexity theory and social life.

    i. Complex systems are nearly always in flux and prone to changes. They can be in dynamic equilibrium (although not in stasis), but are not necessarily so. They are subject to accident, either external or internal. Modes of analysis which work at one time may not at another, because of subtle differences in the system, there is always some ongoing variation.

    ii. Complex systems can be ‘maladaptive’ as well as adaptive and their adaptation need not be beneficial for humans.

    iii. Complex systems interact and have fuzzy boundaries. Social, political, economic, technical and environmental processes are frequently isolated from each other for analytical purposes, but in reality they often interact. These systems do not need to interact harmoniously. For example, the economic system can disrupt the ecological system (which in turn disrupts the economic system), the technical system can change economics and so on.

    iv. Systems (particularly biological ones) can seem complex all the way down. For example, humans are colonies of creatures both at the cellular level and in the amount of non-genetically related life that lives in them, and soils can differ in creatural content (micro-ecologies) over quite small distances.

    v. Complex systems and their subsystems are unpredictable in specific. As they interact with other systems they are always being affected by apparent ‘externalities’ as well as internal complications and variations. Assuming no major change of equilibrium, trends may sometimes be predicted. For example, we can predict that global warming will produce wilder weather, but we cannot predict uniform heat increases everywhere, and we cannot predict the weather in a particular place in exactly three years’ time.

    vi. Small changes can make big differences in system behaviour; as with relatively small changes of temperature. Complex systems can be disrupted by the accumulation of stress which produces ‘tipping points’, after which the system may make an irreversible change into a new form of dynamic equilibrium with only marginal connections to previous states. Tipping points may not always be perceptible beforehand. Changes of system state may also be relatively quick, and if the pressures continue, more changes can follow – this is not necessarily a transition between two stable states (start and end). This possibility of rapid system change increases general unpredictability.

    vii. In complex systems, all human (and other) acts/events have the possibility of being followed by unpredictable, disruptive and disorderly-appearing consequences, no matter how good we think the act. In complex systems, it may also be hard to tell which, of all the events that chronologically succeed the human acts, result from those acts. We are not always able to control the results of even a simple interaction between two people.

    viii. Technologies may be implemented or designed to increase control or extend a group’s power. As the technologies tend to add or change links between parts of the system, and change relative influence, the results of the technology may be disruptive in all kinds of spheres. At least they may have unintended results and open up unimagined courses of action – as when the automobile changed the patterns of people lives, their accident patterns and the layout of cities.

    ix. Unpredictability of specific events, implies that both politics, trading and implementing new technologies, are ‘arts’ involving uncertainty and unintended consequences. This seems more realistic than most views of economics and social action in which uncertainty and unintended consequences are seen as secondary. There is no correct program as such, only a feeling towards a useful direction.

    x. Complexity means that analysis/perception of the system (even the perceived borders of the system) will always vary given a person’s position in that system. Therefore there is rarely much unity as to how the systems work, what should be done or a good guides to political action.

    xi. Partial and incomplete understanding is normal. With no complete understanding, politics (and planning) is an art of attention to what is happening, together with an ability to try out actions and change them as feedback emerges.

    xii. Markets do not give out or represent perfect information, partly because markets are not bounded, but because distortion of information and production of misinformation is a normal political/persuasive tool of marketing and profit and an integral part of capitalist markets and politics, not an aberration.

    xiii. Some highly important complex systems can excluded from consideration by, or become invisible to, members of other systems, because of a history of power relations.
    For example, environments are largely invisible in classical economics, as sacrificing ecologies has so far made money, with the costs of that sacrifice not counting to the companies involved, even if it counts to the other people and beings living in that ecology. If profit is the ultimate value (or trait of survival) and profit is cut by environmental care, then there is always an incentive not to care, to distort information about that lack of care, or suppress those who do care. Environmental destruction is boosted because environment cannot be valued in the neoclassical frameworks which have grown around this despoilation (other than in an arbitrary, gameable, monetary sense). However, on a finite planet, economics is eventually disrupted by an environmental destruction which cannot be left behind. Environment or natural ecologies are not subordinate to economics. Economies are part of ecologies.
    Political decisions and systems affect economics and vice versa, but this is frequently denied. Politics forms the context of economic acts and the rewards available, and economic actors compete within the State for market influence and suppression of other actors, as much as they compete in the market. Unequal wealth allows more political distortion of markets. There is no one set of politics in play at any one time. On the other hand economics forms the context of politics can limit what is possible within the systems.

    xiv. As complex systems flux, decisions and procedures which work well in one series of situations are not necessarily very good in another, or if they are applied more rigorously than previously. They can be ‘extended’ to systems or subsystems where they are inappropriate, or ‘intensified’ so that they become disruptive. Systems tend to produce self-disruptive results as their order is intensified.

    xv. Sustainability, in the sense of preserving a system in a particular state without change, may be impossible, but systems can be maintained in better or worse states for humans.

    xvi. As flux is normal, the results of policies and acts are unpredictable and unclear, and views of the systems partial, politics is always argumentative.

    xvii. Humans have complex needs that depend on the systems they participate in. Utility arises within fluxing systems (cultural, technical, power relations), it is not priori, or ‘natural.’ Consequently value is never fixed. For example, what the powerful do, is nearly always considered to be of greater utility and value than what less powerful people do (and this may change as power relations change). Various materials may only have value if the technical, or other, systems require them, etc.

    xviii. Humans also have non-economic needs, such as a sense of, or relationship to, the place/ecology they live within, health, companionship, trust, stories and so on. Welfare cannot be completely accounted for by money and goods.

    xix. Money may not reflect all human needs, and attempting to reduce needs to money may disrupt awareness of what people need.

    xx. Money has utility and is complex like other utilities, becoming a commodity of variable worth, on the market. Putting a monetary value on one’s child’s life, for example, is difficult. Limiting ideas of welfare to what can be bought and what it is bought with, automatically produces bad conditions for poorer people and disrupts the economy.

    xxi. In the production of ‘goods,’ economies produce waste and potential harms. If the byproducts of production cannot be processed by the ecology it is dumped in, or the waste is poisonous to humans or other creatures and plants then it can be called ‘pollution’.

    xxii. The question arises: ‘is it possible to have an economy without pollution? The distribution of waste and harm, might be as fundamental to political economy as production, exchange or distribution. Waste is dumped on those who lose power battles, or who have already been despoiled. Pollution requires particular relations of power, responsibility and allocation.

    xxiii. What is defined as private property, or public waste, can appear to depend on power relations. This power can be expressed as, issued regulations, the use or threat of violence to exclude others, or exclude other items, from being valued, and the ways of determining and enforcing who or what can be sacrificed for ‘success’ (as well as what counts as success). What counts as commons, also depends on power and defense against appropriation.

    xxiv. ‘Development’ is often seen in terms of increasing total levels of wealth and military security, with some people being marginalised and sacrificed for that aim. It is another example of the interaction of politics and economy. As development is emulative and competitive, it often aims to emulate the prosperity of capitalism.

    xxv. Development can often produce destruction, when wedded to fixed procedures, as when it is seen as tied to coal power. Then it creates coal power interests who fight to stop other forms of power and spread coal elsewhere.

    CO2 and non-linear systems

    December 19, 2018

    The amount of CO2 in the air has dramatic effects out of all proportion to the amount of the gas in the air or in proportion to the amount emitted by humans. It produces a non-linear effect.

    Concentrations of CO2 have been much greater than they are now, in times when there were no humans around. Nobody is arguing that the world would end with much higher CO2 levels, just that relative climate stability would end, as the climate system shifts into new patterns, and human civilization would be extremely likely to suffer significant disruption and possibly destruction depending on how bad it gets.

    As far as we can tell for the last half million years or so CO2 levels have remained between 180 and 300 parts per million (again, that’s pretty low compared to some other geological periods). In the last 100 years or so, this has risen to about to 410 parts per million (people were hoping the rise would stop at 350 parts per million, but it hasn’t).

    There is no indication that this increase in CO2 concentration is slowing. That is a pretty rapid and significant change and most of it seems to have come from human emissions. The theory of greenhouse gases which has been around for well over 100 years would lead us to expect a rise in global average temperatures as a result, and this is happening – and it is happening pretty much as predicted (although a bit higher and more rapid than some official predictions).

    Again it needs to be said that the average temperature rises are relatively small, but these small rises appear to be disrupting climate stability already. What seems small to us can have large effects on the system as a whole.

    Now natural emissions of CO2 are huge – figures usually suggest around 800 giga tonnes per year. Natural ‘carbon sinks’ and conversion processes handle these emissions quite well. Human emissions are much, much, less than that, even now about 30 giga tonnes per year but increasing.

    You might think its a matter of common sense that this little overshoot would not make that much of a difference, but we are not dealing with a simple linear system here. Small changes (in CO2 levels and temperature) can make large differences, due to the way feedback loops work and trigger, or disrupt, other systems.

    For some while these emissions made little difference because natural carbon sinks could deal with the extra burdens – these sinks produced the well known pause in the rate of increase of average temperature (not a decrease in temperature or even a stabilizing of temperature, but a decrease in acceleration of temperature increase). These now seem to have been used up. The more we destroy the ecology and engage in deforestation etc. then the worse the accumulation gets and the higher the temperature increases. The rapidity of the change together with environmental destruction renders natural evolutionary or adaptational processes irrelevant – natural sinks do not appear to be able to handle the increase any more.

    The more that the average temperature increases, the more that some natural sinks will start releasing CO2, methane and other greenhouse gases. For example the Russian Steppes might already be releasing previously frozen methane for more green house emissions.

    This makes the situation even worse; it compounds the problems and shifts them into a whole other realm. We have to stop temperature increases now, if we don’t want extreme weather events to become more and more common, and remediation to become more difficult than it already is. Also as you probably know, land ice is melting and glaciers are disappearing and this will also likely lead to temperature increases and to rising sea levels. Neither of which is good for coastal cities or for human water supplies.

    So if we continue with our current patterns of CO2 emissions we are heading for likely catastrophe – we are certainly not heading for good times.

    This whole process is difficult to predict in its entirety, because of the way local conditions act with global conditions. For example, higher average temperatures could disrupt the patterns of the Gulf Stream which has kept the UK relatively warm. If the Gulf stream moves southward, then parts of Europe could heat up while the UK’s average temperature lowers. Whatever, happens the weather will change and probably change violently. If we do not stabilize CO2 emissions then the system fluctuations will get wilder, as it is subject to greater stress.

    We need to stop CO2 emissions as quickly as possible, and start protecting the rest of the environment to allow its resilience to function. So we have to stop massive deforestation and other forms of pollution as well as stop CO2 emissions.

    Human CO2 emissions largely come from burning fossil fuels, some forms of agriculture, and with some from building (concrete use). For some reason official figures for fossil fuel emissions often split the burning into electricity production, transport, industry, domestic and so on, but they all have the same cause.

    We can pretty much end coal fired power for electricity now if we put money into it and impose regulations bringing coal burning to an end. We are helped in this as building new coal fired power stations is becoming more expensive than renewables, even with all the subsidies that fossil fuel mining and power receives. Ending coal burning won’t necessarily be pretty, but it can be done. Coal is poisonous during the mining and during the burning, and devastates fertile land during mining, so its a good thing on the whole. Petrol/oil burning may be a bit more difficult. We need an excess of renewable power and storage to allow transport to work like it does now. Possibly generating hydrogen from water is one way around that, but we need heaps of excess renewables to do that and that may then come up against material limits. Changing agriculture will be more difficult still, but people are claiming low emissions concrete is becoming available (I’m not sure).

    However, there is a problem, even if we could stop tomorrow. The natural carbon sinks are over-stretched and unlikely to recover quickly. They will not remove the “excess” CO2 from the atmosphere quickly enough to prevent already dangerous average temperature increases. We may need to research Carbon dioxide removal techniques as well. These are being developed, but more money for research is needed, and we need to find some way to dispose of the extracted CO2, so it is not returned to the atmosphere in a couple of years. This is a massive technical problem, which is not really close to being solved (that is a matter of argument, but that is my opinion). Hopefully the problem can be solved.

    We need to cut back emissions quickly. We will then almost certainly need to develop an extraction technology. If we can’t do either of these, then we face truly massive disruption: more extreme weather, flooding, city destruction, people movements, food shortages, and warfare.

    Complexity again

    November 27, 2018

    Another summary

    A complex system is a system in which ‘participants’ and their contexts are either modified by other participants and events in the system or self-modify in response to those participants and events. All living ecologies are complex systems, including social systems. Complexity has several important, and routine, implications including:

  • Complex systems are dynamic and fluxing, producing patterns rather than lasting structures.
  • Systems are rarely lone systems. Patterns tend to overlap having fuzzy boundaries with other systems. This can involve nesting and hierarchies, which may provide temporary limits on variation, but also makes ‘interference’ (both within the system and from ‘external’ systems) normal.
  • Actions taken will frequently produce unintended consequences. Even simple conversations may go in completely unexpected directions with lasting unintended consequences.
  • We cannot understand the world completely due to the numbers of linkages, the variety of effects and the possible changes in participants. Consequently, there will always be gaps in knowledge and expectation, which add to uncertainties and unexpectedness. We can call this unknown a social ‘unconscious’, and explore its dynamics and effects.
  • Large-scale transitions can arise from quite small events. Greater accuracy of measurement may not give greater certainty, but give completely different predictions, as actions do not always cancel each other out statistically. Similarly, statistical ‘long tails’ can have large effects.
  • While systems are unpredictable in specific, they can sometimes be predictable by trend and pattern. For example, we can predict a continuing rise in global temperature and climate turmoil if we do not change various activities, but we cannot predict weather patterns at a particular time, and our accuracy decreases the further into the future we go.
  • Despite this variability, there seem to be patterns of transition which can be used to postulate, or interpret, the type of course events may take.
  • Vague thoughts about economics

    November 2, 2018

    1) Producing goods involves waste and environmental destruction. This cost can be counted or not, depending on the power of the destroyer and the convenience of destruction. It still has an effect. How do we make sure that the waste an destruction can be processed by the Systems involved? If economics and waste breaks the boundaries of the earth system, then we are all under considerable pressure, if not dead. We are not yet able to treat the planet as if it was not a closed set of systems.

    2) Wealth equals power in the market and in society. Power can be used to alter the structures of markets to prevent innovation and the distribution of goods to people who need them. This may not always have the effects intended, by those powerful. Hence a functional economics which is not just about protecting the wealthy, has to recognise politics and power inequalities and seek to subvert them.

    3) Markets do not always work to maximise social benefits for everyone (through the “invisible hand” or otherwise, so it is probably false to claim that as a principle of economics. Perhaps we should more realistically start economics with looking at how markets do not achieve this, and are not intended to achieve this?

    4) When dealing with climate change we should probably think about the general disorganisation, disruptions and costs that come from not doing anything. This is the base cost of action.

    5) There is no reason to assume the least cost intervention will be the best, although it is, by definition, probably least costly to the powerful wealthy and therefore to be favoured.

    6) We may need to identify those people who will resist any intervention, and why. This takes us out of economics.
