The specter of global planning

Vaclav Klaus writes,
As someone who lived under communism for most of his life, I feel obliged to say that I see the biggest threat to freedom, democracy, the market economy and prosperity now in ambitious environmentalism, not in communism. This ideology wants to replace the free and spontaneous evolution of mankind by a sort of central (now global) planning.

The environmentalists ask for immediate political action because they do not believe in the long-term positive impact of economic growth and ignore both the technological progress that future generations will undoubtedly enjoy, and the proven fact that the higher the wealth of society, the higher is the quality of the environment. They are Malthusian pessimists.

...

Due to advances in technology, increases in disposable wealth, the rationality of institutions and the ability of countries to organise themselves, the adaptability of human society has been radically increased. It will continue to increase and will solve any potential consequences of mild climate changes...

As a witness to today's worldwide debate on climate change, I suggest the following:
  • Small climate changes do not demand far-reaching restrictive measures
  • Any suppression of freedom and democracy should be avoided
  • Instead of organising people from above, let us allow everyone to live as he wants
  • Let us resist the politicisation of science and oppose the term "scientific consensus", which is always achieved only by a loud minority, never by a silent majority
  • Instead of speaking about "the environment", let us be attentive to it in our personal behaviour
  • Let us be humble but confident in the spontaneous evolution of human society. Let us trust its rationality and not try to slow it down or divert it in any direction
  • Let us not scare ourselves with catastrophic forecasts, or use them to defend and promote irrational interventions in human lives.

Global warming is our Cold War

Josie Appleton notes that in the early twenty-first century,

...the political climate colours models of nature. We can see how social anxieties – a fear of change, a sense of the fragility of things – guide the questions that scientists ask, and the kinds of theories that ring true.

That doesn’t mean, of course, that these theories are incorrect. Every theory of nature to some extent draws its metaphors from the society of the time...

As a rule of thumb, the more self-critical the science, and the more it tests itself against reality, the more accurate it will be. If all theories draw their metaphors from society, some do so justifiably – in a way that grasps nature’s real operation – and some do in a way that merely distorts and mystifies...

The less self-reflective the science, and the more it is founded on political and moral campaigns, the less reliable it is likely to be. And in [Mark Lynas' Six Degrees: Our Future on a Hotter Planet], we see how global warming science has become a foil for a whole series of political and moral agendas, a way of discussing everything from the sins of consumerism to human arrogance. Outlining the effects of a four degrees rise in temperature, Lynas writes: ‘Poseidon [God of the sea] is angered by arrogant affronts from mere mortals like us. We have woken him from a thousand-year slumber, and this time his wrath will know no bounds.’ Not only Poseidon and Gaia but also terms such as ‘Mother Nature’ and ‘nature’s revenge’ have slipped into everyday discussion about climate change. Darwin did not, so far as we know, give names of Gods to his finches. When scientific concepts start to be discussed in such emotional terms, it suggests that they say more about wish than reality.

The scope for climatology to slip into fantasy is heightened by the fact that it is a relatively open and uncertain field. Time and again in the twentieth century, climate scientists noted how shaky their art was. It was a case of one man, one model, and everybody thought that theirs was the right one. Today’s models include many interacting factors that are incompletely understood, and different models can produce drastically different results...

That doesn’t mean that global warming doesn’t exist, but it does mean that many of these predictive models currently being produced are likely to be extremely inaccurate, verging on total fantasy. Any form of science that is morally and politically loaded, and involves putting large numbers of variables into a computer to predict changes for 50 years hence that cannot be tested, is going to be distorted. While the world’s climate does appear to have warmed - the earth is on average 0.7 degrees warmer than it was 150 years ago, before large-scale industrialisation – it’s a fair leap from 0.7 degrees to apocalypse...

Today’s preoccupation with fragility and collapse means that models take a one-sided view of nature...

To recap, it is perhaps political rather than scientific analysis that can help us to understand the bias that underlies today’s climate science. The notion of nature as fragile and subject to collapse is a relatively recent one, which is likely to owe more to the anxious zeitgeist than to climate realities. There are two more aspects of Six Degrees that are worth discussing. First, its notion that tackling climate change is an historic challenge; and second, its idea that global warming holds within it moral lessons, for humanity and for individuals. These help to explain why the idea of global warming is now so compelling and has come to dominate public life. For it provides, not just an expression of anxiety, but also a way out of that anxiety: a way of reframing the big issues of historical purpose and personal morality.

Lynas is an historian by training, and in his book we can see how global warming provides a way to frame the past and the future. He presents climate change as the great causal factor of history...

As historical analysis, this is cruder than the crudest Marxism...

Carbon dioxide becomes the invisible hand behind events, the determining element underlying possible future outcomes for humanity. We make global warming and then it will make us.

...global warming also plays a teleological role: it provides a decisive point towards which history is heading, and provides an overall meaning for events. A decade-and-a-half after Francis Fukuyama announced the ‘end of history’, environmentalists have apparently found an occasion to which we must rise. The impending ‘climate crisis’, and our need to respond, is the first post-political narrative that has aroused significant passion or conviction. It is the first post-political notion of an historic task, a decisive future event that will determine humanity’s fate. It is perhaps the only way in which today’s society can discuss the idea of the judgement of the future, or the condition of life for our children. Hence, the dramatic sweep of the campaign against global warming throughout the elite – especially members of the political elite who spent periods in the cold. This is Al Gore on what global warming means to him:

‘The climate crisis also offers us the chance to experience what very few generations in history have had the privilege of knowing: a generational mission; the exhilaration of a compelling moral purpose; a shared and unifying cause; the thrill of being forced by circumstances to put aside the pettiness and conflict that so often stifle the restless human need for transcendence; the opportunity to rise…. When we do rise, it will fill out spirits and bind us together. Those who are now suffocating in cynicism and despair will be able to breathe freely. Those who are now suffering from a loss of meaning in their lives will find hope.’ (7) (His italics.)

The notion of teleology that appeared first in Christianity (Christ’s birth, death and return), then liberalism (progress towards a state of perfect liberty), and then certain brands of Marxism (the development of productive forces, leading towards revolution), appears now in the form of climatology. The progress of civilisation is re-read in terms of the accumulation of carbon dioxide, which will eventually – and as a result of feedback that occurs independently of human will – lead to a dramatic transformation in the planet’s climate...

While revolution was a vast collective effort, raising human energy and consciousness to a pitch, the fight against climate change is about a vast collective restraint, a pulling back on the reins. We must cut back, and learn to live humbler and slower lives. In Carbon Counter: Easy Ways to Reduce Your Carbon Footprint, published around the same time as Six Degrees, Lynas describes his ‘visions of a sustainable Britain’, which includes a ‘quieter, slower life, where people take more time when travelling and travel less’. In Six Degrees, he says that in the low-carbon society we would finally realise that ‘our planet is a unique gift…which we are indescribably privileged to be born into’.

The low-carbon society is above all calm. According to Lynas, the battle against global warming will allow us to cure the problem of human hubris, which has been the defining feature of what he calls the ‘Anthropocene’. In the low-carbon society, human beings’ restless desire to improve themselves will be gone. We will live locally, we will be thankful, we will make do. Children would be able to play in the street again; airports would be converted back into forests... In the post-Anthroprocene, or perhaps we should call it the Ecocene, we are appointed ‘de facto guardians of the planet’s climate stability’; our mission is regulating the thermostat. In a currently popular phrase, we will become ‘caretakers of the planet’.

Life beyond consumerism would be a fine thing, but this is life without a pulse. Every dream of the destiny of history has been one in which human wishes were fulfilled, where people were free to follow their desires, released from the fetters that hold them back. It is this same theme that runs through imagined post-revolutionary societies, and promised lands flowing with milk and honey. The low-carbon society, by contrast, is one in which fetters are strengthened: our trouble is that we have ‘broken out of the ecological straightjacket’, Lynas says disapprovingly. It is difficult to see how this vision of the future will play. Fight to put the ecological straightjacket back on! Vote to manage the planet’s climate stability!...

The campaign against global warming provides answers so that we no longer have to think about the questions. In Gore’s words, this is ‘the thrill of being forced by circumstances’. The certainty of planetary emergency seems to provide a cause that is solid, a cause that is not chosen and therefore beyond dispute and doubt. It is this relief of finding a point of ideological certainty that explains the grip of global warming on the contemporary imagination. Hence the missionary zeal of believers, and the fact that people now discover global warming in periods of doubt, just as they once used to find God in prison... To understand, we must look not to science but to politics, to the existential needs that mean that the notion of global warming ‘feels right’.

Lynas’ Carbon Calculator shows the way in which global warming also provides a new structure for personal life...

Carbon becomes the universal moral measure, a stick that can be applied to pretty much every activity and possession...

Carbon dioxide becomes the nexus between individuals, the thing that connects us to other people and to the future of the planet. This infuses the most banal acts with a deep moral meaning... In the main, that effect is negative: by seeking to fulfil our own wants and pursue our own goals, we are condemning other people to death. The way we help the whole is by reining in our wants, for example by buying strawberries in summer only.

The carbon calculator involves an almost pathological indifference towards the significance of the things we do. Plane journeys to see sick relatives or to visit prostitutes are weighed the same, in parts per million. The ways in which human beings judge whether something was worthwhile – Did it have a useful result? Did it bring joy or pain? – are suspended. The planet doesn’t care either way. The planet’s indifference to the passions and trials of human life becomes the worldview we ourselves assume. Again, we see how global warming appears to provide the answer to a dilemma – how we live, and how we should structure and judge our lives – but that it does that by abolishing the question. It solves the dilemma of moral meaning by abolishing all meaning...

When global warming becomes so laden with moral meaning, it becomes difficult to approach it as an environmental problem – to work out to what degree it is a problem, and what would be the most appropriate response...

... Lynas criticises the notion that ‘the white knight of technology will come riding to the rescue’ – this is in fact ‘the most pervasive and enduring form of denial’. There is no ‘miracle energy cure’, says Lynas. Indeed, you often hear environmentalists say that the hopes of a ‘silver bullet’ to solve global warming is merely ‘avoiding’ the question. Avoiding how? What they mean is that it is not energy production that must change; it is us. Global warming is not a problem to be solved; it is a lesson to be lived. Lynas writes: ‘The faith in a “techno-fix” evades the need for any serious behavioural change.’

Global warming is so often talked about as a result of our selfishness that we do not see quite how absurd this is. Imagine telling 1950s Londoners that there is no techno-fix to the problem of air pollution, and that they need to monitor and cut their coal use. Smokeless fuels would just allow them to continue in their destructive behaviour, without reflecting on the harm caused by their actions. Their warm sitting room is killing children, and they must take responsibility for that.

Think about that quote from Gore: ‘The climate crisis also offers us the chance to experience what very few generations in history have had the privilege of knowing: a generational mission; the exhilaration of a compelling moral purpose; a shared and unifying cause; the thrill of being forced by circumstances to put aside the pettiness and conflict that so often stifle the restless human need for transcendence….’ Global warming offers us the chance to experience what few generations have had the privilege of knowing. It is a thrill, no less. Global warming is our Cold War. And just as American strategists worried at the end of the Cold War about the loss of the Red opposition, so environmentalists have a kind of attachment to global warming.

Of course, they talk about it being ‘inconvenient’, and they wouldn’t have wished it upon the world... Global warming is now not so much a problem to solve, as an issue around which to reorganise society. This is more Noah’s flood than Clean Air Act, and the lesson is in the sins of hubris and consumerism. Global warming is sent to show people that (in Lynas’ words) they are ‘wasting their lives commuting to work in cars’. His proposed solution – to ‘cut our need for energy by living less consumptive lifestyles’ – will apparently form the basis of a new and happier society.

All the arm-twisting in the world is not going to stop India and China flying, a fact shown by recent figures showing a massive boom in air travel. Daily media guilt-mongering has not stopped British people from enjoying weekends in Budapest or Prague, and nor should it. Governments, we can hope, will still be elected in 2050, and while that is the case carbon rations would still be ‘politically unrealistic’. Unless we live under a dictatorship of some Global Commission for the Environment then energy use will continue to rise dramatically; the only question is whether this energy comes from fossil fuels or some other source. And if it needs to come from some other source, we need a techno-fix.

Techno-fixes are not some airy-fairy notion, some leap of faith. This is otherwise known as innovation, the only way that environmental problems have ever been solved or new energy systems produced. I am not aware of a major environmental problem successfully tackled by the mass of people consciously and systematically abstaining from some or other desirable activity. The lesson of history is that techno-fixes happen, and they happen fast in societies that are looking for solutions...

Livestock generates more greenhouse gas than transport

Which causes more greenhouse gas emissions, rearing cattle or driving cars?

Surprise!

According to a new report published by the United Nations Food and Agriculture Organization, the livestock sector generates more greenhouse gas emissions as measured in CO2 equivalent – 18 percent – than transport. It is also a major source of land and water degradation.
I missed that one.

old news on global warming

...many environmental campaigners, including the former U.S. vice president, Al Gore, and some scientists have portrayed the growing human influence on the climate as an unfolding disaster that is already measurably strengthening hurricanes, spreading diseases and amplifying recent droughts and deluges.

Conservative politicians and a few scientists, many with ties to energy companies, have variously countered that human-driven warming is inconsequential, unproved or a manufactured crisis.

A third stance is now emerging, espoused by many experts who challenge both poles of the debate.

They agree that accumulating carbon dioxide and other heat-trapping smokestack and tailpipe gases probably pose a momentous environmental challenge, but say the appropriate response is more akin to buying fire insurance and installing sprinklers and new wiring in an old, irreplaceable house (the home planet) than to fighting a fire already raging.
So far, so good. But then,
"Climate change presents a very real risk," said Carl Wunsch, a climate expert at the Massachusetts Institute of Technology. "It seems worth a very large premium to insure ourselves against the most catastrophic scenarios."
How large?
"Claiming we can calculate the probabilities with any degree of skill seems equally stupid," he said.
So again, how large the premium?

Statistically undetectable

...you might want to read the December issue of the Journal Of Atmospheric And Solar-Terrestrial Physics in which Cornelis de Jager of the Royal Netherlands Institute for Sea Research and Ilya Usoskin of the Sodankyla Geophysical Observatory in Finland test the validity of two current hypotheses on the dependence of climate change on solar energy -- the first being that variations in the tropospheric temperature are caused directly by changes of the solar radiance (total or spectral), the other that cosmic ray fluctuations, caused by the solar/heliospheric modulation, affect the climate via cloud formation. The Finn and the Dutch guy from the A-list institutions with the fancypants monikers writing in the peer-reviewed journal conclude that the former is more likely -- that tropospheric temperatures are more likely affected by variations in the UV radiation flux rather than by those in the CR flux.
...when you do read the actual science, you quickly appreciate that it's not by any means "settled" -- that there all kinds of variables. To quote the Finnish-Dutch bigshots:
"There is general agreement that variations in the global (or hemispheric) tropospheric temperature are, at least partly, related to those in solar activity (e.g., Bond et al., 2001; Solanki and Krikova, 2003; Usoskin et al., 2005; Kilcik, 2005)." Therefore: "Variations of the mean tropospheric temperature must include stratosphere-troposphere interaction."
However: "A detailed mechanism effectively transferring stratospheric heating into the troposphere is yet not clear."
...In the course of the 20th century, the planet's temperature supposedly increased by 0.7 degrees Celsius, which (for those of you who want it to sound scarier) is a smidgeonette over 1 degree Fahrenheit. Is that kinda sorta staying the same, or is it a dramatic warming trend?
And is nought-point-seven of an uptick worth wrecking the global economy over? Sure, say John Kerry and Al Gore, suddenly retrospectively hot for Kyoto ratification. But, had America and Australia signed on to Kyoto, and had Canada and Europe complied with it instead of just pretending to, by 2050 the treaty would have reduced global warming by 0.07C -- a figure that would be statistically undetectable within annual climate variation. And, in return for this meaningless gesture, American GDP in 2010 would be lower by between $97 billion and $397 billion -- and those are the U.S. Energy Information Administration's somewhat optimistic models.
And now Jerry Mahlman of the National Center for Atmospheric Research says "it might take another 30 Kyotos" to halt global warming. Thirty times $397 billion is... er, too many zeroes for my calculator.
So, faced with a degree rise in temperature, we could destroy the planet's economy, technology, communications and prosperity. And ruin the lives of millions of people.
Or we could do what man does best: adapt. You do the math.
