Climate Science Gets Serious

FOR YEARS, I’ve scoffed at the Al Gores of the world and their bribed apologists in the science community. Time after time, they have presented single point departures from an assumed eternal climate equilibrium and forecast imminent disaster unless we did something. And that something usually involved giving them emergency powers to change the world.

I’ve always said that the big climate issue for mankind is ice ages. What’s the point of reducing greenhouse gases in a heroic renunciation of SUVs if it just brings on the next ice age?

But now comes Bill Ruddiman from the University of Virginia in Climatic Change with the news that climate change didn’t start in 1800 with James Watt and the steam engine. It started about 8,000 BP with the invention of agriculture. And it looks like we have already managed to stave off the next ice age with our evil deforestation of the planet.

Ruddiman’s theory is pretty simple. About 8,000 years ago, mankind started clearing forests for agriculture. This released lots of carbon dioxide into the atmosphere. About 5,000 years ago we started flood rice cultivation. That increased the release of methane into the atmosphere. This combination of greenhouse gases arrested a global cooling trend that had started about 10,000 years ago.

Ruddiman accepts as established fact that the ice age cycle is driven by cyclical fluctuations in energy received from the sun that seem to exhibit a cycle of about 20,000 years. The last peak in “insolation” occurred just about 10,000 years ago, when the sun delivered in midsummer about 505 watts of energy per square meter . Right now, according to the natural fluctuation in the solar energy, we should be receiving insolation at about 475 watts per square meter and plunging into an ice age. Only we aren’t in an ice age. Ruddiman says you can thank the family farmer for that.

Of course, since the industrial revolution, we moderns have added about 150 billion tons of carbon to the atmosphere to the 300 billion tons previously put there by the world’s farmers during the age of agriculture. Our human activities are placing a bigger and bigger bet on the world’s future. But the date of the Fall into environmental sin must now be pushed back from 200 years in the past to 8,000 years in the past. It puts a different aspect on things.

It is one thing to say that we have suddenly polluted an innocent world with our industrial filth; it is another thing to say that our current industrial age intensifies trends initiated 8,000 years ago by the first farmers. Especially if it seems likely that man-made climate change has staved off a plunge into a new ice age.

The presumption at the core of the environmental movement is that the planet enjoyed a “natural” environment until the dawn of the industrial age, and that if we act now we can restore its natural state before it is too late. But Ruddiman shows that we have been influencing the climate much longer than that. It is already too late to return to an environmental Eden.

But if it is no longer possible to return to Eden, then life becomes more complex. We must like Adam and Eve look forward not back. If we humans are going to influencing the global climate, for good or ill, what do we want to do with it? Would we like to move the temperate zones north or south? Would we like the ocean level higher or lower? What would be the ideal monsoon for South Asia and its 1.5 billion people? And who is “we?” So far, the climate debate has been shockingly Eurocentric. What will global warming do to the Chinese? What will it do for South Asia? For Africa?

The answer is probably close to the advice tendered by ecologist Daniel Botkin in Discordant Harmonies. Nature fluctuates in all time scales, but it cannot respond to change too fast. For instance, the North American forests have migrated north and south across the continent many times in response to climate change. They will do so again, but they would prefer that the change weren’t too sudden. Likewise, humans have migrated across the world for millennia in search of better living conditions, and will continue to do so. Intelligent and adaptable, we will continue to respond and to migrate. But we would prefer if the change weren’t too sudden. We must decide what we want to grow in our garden and face the consequences of our decisions.

We can no longer return to the Garden of Eden. We never could. We must go on, and not look back. But that is nothing new for humans, for the biosphere, or indeed, for the entire universe.

Responsibility

Seeckt: "to make of each individual member of the army a soldier who, in character, capability, and knowledge, is self-reliant, self-confident, dedicated, and joyful in taking responsibility [verantwortungsfreudig] as a man and a soldier."
MacGregor Knox et. al., The dynamics of military revolution, 1300-2050

Living the Virtues

When recurrently the tradition of the virtues is regenerated, it is always in everyday life, it is always through the engagement by plain persons in a variety of practices, including those of making and sustaining families and households, schools, clinics, and local forms of political community.
Alasdair MacIntyre, After Virtue

Moral Imperatives of Modern Culture

These emerge out of long-standing moral notions of freedom, benevolence, and the affirmation of ordinary life... I have been sketching a schematic map... [of] the moral sources [of these notions]... the original theistic grounding for these standards... a naturalism of disengaged reason, which in our day takes scientistic forms, and a third family of views which finds its sources in Romantic expressivism, or in one of the modernist successor visions.
Charles Taylor, Sources of the Self

US Life in 1842

Families helped each other putting up homes and barns. Together, they built churches, schools, and common civic buildings. They collaborated to build roads and bridges. They took pride in being free persons, independent, and self-reliant; but the texture of their lives was cooperative and fraternal.
Michael Novak, The Spirit of Democratic Capitalism

Society and State

For [the left] there is only the state and the individual, nothing in between. No family to rely on, no friend to depend on, no community to call on. No neighbourhood to grow in, no faith to share in, no charities to work in. No-one but the Minister, nowhere but Whitehall, no such thing as society - just them, and their laws, and their rules, and their arrogance.
David Cameron, Conference Speech 2008

Faith and Politics

As far as the Catholic Church is concerned, the principal focus of her interventions in the public arena is the protection and promotion of the dignity of the person, and she is thereby consciously drawing particular attention to principles which are not negotiable... [1.] protection of life in all its stages, from the first moment of conception until natural death; [2.] recognition and promotion of the natural structure of the family... [3.] the protection of the right of parents to educate their children.
Pope Benedict XVI, Speech to European Peoples Party, 2006

Never Trust Experts

No lesson seems to be so deeply inculcated by the experience of life as that you should never trust experts. If you believe doctors, nothing is wholesome: if you believe the theologians, nothing is innocent: if you believe the soldiers, nothing is safe. They all require their strong wine diluted by a very large admixture of insipid common sense.
Lord Salisbury, “Letter to Lord Lytton”

Conservatism's Holy Grail

What distinguishes true Conservatism from the rest, and from the Blair project, is the belief in more personal freedom and more market freedom, along with less state intervention... The true Third Way is the Holy Grail of Tory politics today - compassion and community without compulsion.
Minette Marrin, The Daily Telegraph

Class War

In England there were always two sharply opposed middle classes, the academic middle class and the commercial middle class. In the nineteenth century, the academic middle class won the battle for power and status... Then came the triumph of Margaret Thatcher... The academics lost their power and prestige and... have been gloomy ever since.
Freeman Dyson, “The Scientist as Rebel”

Government Expenditure

The Union publishes an exact return of the amount of its taxes; I can get copies of the budgets of the four and twenty component states; but who can tell me what the citizens spend in the administration of county and township?
Alexis de Tocqueville, Democracy in America

Conservatism

Conservatism is the philosophy of society. Its ethic is fraternity and its characteristic is authority — the non-coercive social persuasion which operates in a family or a community. It says ‘we should...’.
Danny Kruger, On Fraternity

Postmodernism

A writer who says that there are no truths, or that all truth is ’merely relative’, is asking you not to believe him. So don’t.
Roger Scruton, Modern Philosophy
