Civilisation

How Civilisations Die

Mervyn F. Bendle

Is demography destiny? And does drastic demographic decline entail the death of civilisations? Iranian President Mahmoud Ahmadinejad believes it does, and that the plummeting fertility rates in his country foretell the inevitable doom of his Muslim theocratic tyranny. “Negative population growth will cause the extinction of our identity and culture,” he rages. He views it as a self-inflicted “act of genocide” by the young women of Iran.

Demographic decline is, of course, a dread future that has confronted the West for some time. As Mark Steyn observes in America Alone: The End of the World as We Know It (2006), Europe faces the “Four Horsemen of the Eurocalypse”:

Death—the demise of European races too self-absorbed to breed; Famine—the end of the lavishly-funded statist good times; War—the decline into bloody civil unrest that these economic and demographic factors will bring; and Conquest—the re-colonization of Europe by Islam.

However, the Muslim world faces a similar demographic calamity, as David Goldman explains in How Civilizations Die (And Why Islam is Dying Too) (2011). In his view the approaching disaster will indeed engulf Europe and other developed economies but then, after some decades, it will also devastate the Muslim world. The key difference will be that Europe possesses considerable economic, cultural and institutional resources to draw upon to alleviate the impact; Islam, on the other hand, will not be so fortunate, and when the blow comes, in the latter half of this century, it will devastate what remains of that civilisation.

This calamity, Goldman argues, betrays a terminal malady, a debilitating cultural despair—a nihilism—that is rapidly corroding the finely knit cultural and social fabric that sustains all civilisations—although, as the parenthetical subtitle suggests, he doubts that contemporary Islam actually constitutes a coherent civilisation. (Indeed, the image of a coherent and benign “Islam” that we are presented with in the West is largely a confection of public relations firms, compliant politicians and media, and academics funded by copious amounts of petro-dollars.) Nevertheless, Islam confronts a catastrophe that may easily dwarf that facing Europe and other advanced societies.

The implications of this are profound. As Goldman observes about the decline of civilisations in general: “the death of a culture is an uncanny event, for it erases not only the future but also the past, that is, the hopes and fears, the sweat and sacrifice of countless generations whose lives no longer can be remembered”. Goldman believes that there is a civilisational tipping point, a moment when the spiritual and cultural resources of a people or a nation are exhausted or destroyed and it is no longer possible for them to attain or retain a sense of immortality through participation in a great chain of generations stretching from the past into the future. At this point some nations “fight to the death. Others cease to breed. Some do both.” Global politics over the next half-century will be determined largely by which countries choose which of these paths.

The nature and scale of the global demographic future are becoming ominously clear. As Goldman points out, on present trends, “in the second half of this century most of the great powers of the past—Germany, Spain, Italy, Russia, and Japan, among others—will cease to function. A century later they will have ceased to exist.” In Western Europe, by 2100 the working-age population will have fallen by about 40 per cent, and in Eastern Europe, Russia, and East Asia by some 66 per cent. The least fertile European nations face a population decline of 40 to 60 per cent, with Germany’s population projected to decline by 98 per cent over the next 200 years if present trends continue.

Simultaneously, in all these countries the old-age dependency ratio (the ratio of people aged sixty-five and over to those of working age, fifteen to sixty-four years) will increase significantly, especially over the next few decades, placing huge burdens on the economic systems and social structures of these countries. Locked in a “demographic death spiral … Economies and tax revenues across Europe and East Asia will implode while pension and health care costs skyrocket”, according to Goldman.

Goldman doesn’t mention Australia, but our overall demographic profile is similar to Europe’s although our situation is nowhere near as grave. Our population is projected to grow to 36 million by 2056 and 45 million by 2101, on the most likely trends, according to the Australian Bureau of Statistics (ABS). On these trends, the proportion of people aged sixty-five years and over will increase from 13 per cent in 2007 to 23 per cent in 2056, while the working-age population will decline from 67 per cent in 2007 to 60 per cent in 2056. As a result, the old-age dependency ratio will increasing from 1:5 to more than 1:3, a challenging but manageable situation, certainly in comparison to Europe, and one largely managed by continuing high levels of immigration.

In comparison, Islam faces a catastrophe. In Goldman’s view:

if demographic winter is encroaching slowly on the West, a snap frost has overtaken the Muslim world. Europe has had two hundred years to make the transition from the high fertility rates of rural life to the low fertility rates of the industrial world. Iran, Turkey, Tunisia and Algeria are attempting it in twenty.

These and other Muslim countries presently have disproportionately large populations of teenagers and young adults, trapped in long-term unemployment and under-employment, or wasting their time at sub-standard universities that produce hundreds of thousands of unwanted graduates who are presently being radicalised in the “Arab Spring”. They are the progeny of previous generations where the average family had six or seven children, but will themselves have only one or two children on average. The result will be an eventual demographic “train wreck”, according to the scenario described by Goldman, as this huge cohort ages amid economic stagnation and political chaos and comes to depend on the next generation for support that will not be there.

For example, at present there is only one elderly dependant for every nine working-age Iranians—producing an old-age dependency ratio of 1:9; but in 2050 that ratio will be 7:10, meaning that the economic burden of the elderly on working-age Iranians will be over six times greater than at present. The Iranian economy is already in a parlous state, with a 50 per cent inflation rate, and the output from its declining oil reserves is projected to halve by 2050. And Iran is a benighted, corrupt, theocratic state that has resolutely turned its back on almost all aspects of modern culture, alienating a vast proportion of its population. Prospects are unremittingly bleak and people are acting accordingly in the one area of their lives where the state cannot (yet!) intrude. Unsurprisingly, in 2010 Ahmadinejad denounced the increasingly prevalent “two children per woman” attitude amongst Iranians as “a formula for the extinction” of Iran.

The Iranian leadership has only slowly become aware of the approaching demographic disaster. In 2006 Ahmadinejad had declared that Iranian girls should marry at the age of sixteen and commit themselves to producing the six or seven children necessary to avoid the looming depopulation of their country. The women of Iran responded by dropping the average fertility rate even further, to 1.7 in only four years. Moreover, the situation is worse amongst the dominant Persian population, which constitutes a slim majority in Iran and is confronted with eventual engulfment by a range of sizeable and more fecund minorities, including the increasingly restless Kurds, Azeris, Arabs and Baluchis. Already, in the capital, Tehran, the rate is only 1.5, emphasising the extent to which urban women are recoiling from the grim future that is unfolding in Iran.

Ahmadinejad believes the drop in fertility in Iran is part of a Western plot to seduce Iranian women into a life of consumerism rather than reproduction, ignoring the fact that the decline started in 1980, immediately after the Islamic Revolution that brought the present regime to power. This conspiracy theory is shared by another Islamist national leader, Tayyip Erdogan, the Prime Minister of Turkey. “They want to eradicate the Turkish nation,” he declared in 2008, and called upon Turkish women to have at least three children each. The reaction was negative, and the demand for contraceptives apparently rose.

A similar situation confronts most of the Muslim world, which is shadowing the depopulation of the West but with about a half-century time-lag. As Goldman points out:

a good deal of the world seems to have lost the taste for life … The world’s population will fall by as much as a fifth between the middle and the end of the twenty-first century, by far the worst decline in human history.

While there has been recognition in the West that plummeting fertility will create enormous problems, especially in Europe where some countries have already passed the demographic point of no return, the fate facing the Muslim world is even bleaker.

Even though its population profile is presently much younger than the West, the fall in Muslim fertility rates is precipitant—indeed, it is “the fastest demographic decline ever registered in recorded history”, as Goldman notes. “World fertility has fallen by about two children per woman in the past half century [but] fertility in the Muslim world has fallen two or three times faster”, especially amongst Arab, Persian, Turkish, Malay and South Asian Muslims. For example, fertility in Iran has fallen phenomenally, by nearly six children per woman, closely followed by Turkey (by five), Egypt and Indonesia (four), and Pakistan (three).

But while the West probably possesses the economic resources and political infrastructure necessary to manage an unprecedented transition to smaller, older populations—albeit with considerable dislocation and turmoil—the Muslim world has nothing comparable. “As Muslim fertility shrinks at a rate demographers have never seen before”, it is closing quickly on the ageing West so that “by the middle of this century, the belt of Muslim countries from Morocco to Iran will become as gray as depopulating Europe”, but with as little as one tenth of Europe’s economic capacity to deal with the problem.

The political implications of this situation are ominous: “the sense of impending doom that pervades much of the Muslim world makes these countries dangerous and unstable”. As far as militant Islamism is concerned, Goldman entertains no illusions. History shows that people entombed in a dying culture “live in a twilight world. They embrace death through infertility, concupiscence, and war.” Consequently:

imminent population collapse makes radical Islam more dangerous, not less so. For in their despair, radical Muslims who can already taste the ruin of their culture believe that they have nothing to lose … Nations confronting their own mortality may choose to go down in a blaze of glory … Radical Muslims will fight to the death

—in accordance with the frequent boast of the fanatical Islamist: “You love life, we love death”—an assertion that now seems only half right, and it’s the wrong half.

Obviously, this apocalyptic prospect has immense implications for legal and illegal immigration into Europe and elsewhere, particularly as the situation in Iran deteriorates and the violent and authoritarian nature of the forces contesting the “Arab Spring” become more obvious. Increasingly large masses of Muslims are gazing longingly across the Mediterranean at the affluent but vulnerable welfare states that beckon, and beginning what many see as the “re-colonisation” of Europe by Islam. Smaller but increasingly significant numbers are also casting a covetous gaze in the opposite direction, to the southern outposts of European civilisation in Australia and New Zealand.

The spectre of Eurabia, with the continent dominated by a Muslim majority by century’s end, has long haunted vigilant scholars and commentators, such as Bat Ye’or (Eurabia: The Euro-Arab Axis, 2005); Tony Blankley (The West’s Last Chance: Will We Win the Clash of Civilizations?, 2005); Walter Laqueur, (The Last Days of Europe, 2007); and Christopher Caldwell (Reflections on the Revolution in Europe: Immigration, Islam, and the West, 2009). According to these analyses, we are living through the self-extinction of the European civilisation that shaped the world we live in.

Caldwell points out that nearly 11 per cent of the European population was born overseas, most of whom are Muslims who are successfully resisting integration into their host societies. In Civilization: The West and the Rest (2011), Niall Ferguson observed:

if the Muslim population of the UK were to continue growing at an annual rate of 6.7 per cent (as it did between 2004 and 2008), its share of the total UK population would rise from just under 4 percent in 2008 … to 28 per cent in 2040, finally passing 50 per cent in 2050.

Various other demographic projections indicate that the Muslim communities in Italy and Sweden will more than double over the next twenty years; France will be an Islamic republic by 2048; Muslims will form a majority in Holland by 2030; and Germany will follow suit shortly after that. The late Libyan President Gaddafi boasted in 2006 that “the 50 million Muslims of Europe will turn it into a Muslim continent within a few decades”.

The threat of Eurabia, it now seems, is much closer than this vision of a stealthy takeover implies, as the Arab countries in North Africa and the Middle East slip further into crisis. In Goldman’s view:

we may not have the opportunity to observe at leisure how demographic trends in the Muslim world play out. The childless twenty-somethings of Islam’s Generation X do not have to wait another forty or fifty years until they face starvation upon retirement. They are hungry now.

Consequently, it is not a protracted process of demographic conquest that faces Europe in the near future but “inundation by Muslim refugees fleeing the chaos” unfolding in their homelands.

The 16 million people of Tunisia and Libya are already one source of increasingly desperate illegal immigrants as their nations disintegrate and fall under the domination of the Muslim Brotherhood or similar Islamist regimes. Egypt, however, has 82 million people and is also on the verge or political and economic collapse as the Muslim Brotherhood and Salafist groups tighten their grip. As Goldman points out, this is a land where (according to World Health Organisation estimates) 97 per cent of married women have suffered genital mutilation, 40 per cent are functionally illiterate, and half the population lives on about $2 a day. It also has a dysfunctional political system, a corrupt military, a failing economy, a disappearing tourism industry, fleeing capital and shrinking foreign reserves, and needs to import half its wheat and other foodstuffs in volatile markets if its people are not to starve.

Unsurprisingly, Goldman foresees a catastrophe of “biblical proportions” unfolding in Egypt, sending a massive wave of refugees across the Mediterranean. “The simultaneous demographic decline of Europe and the adjacent Muslim countries may bring about mass starvation, political instability, and an unmanageable refugee crisis—and common ruin—before the end of the present century.”

How and why has this situation arisen? Demographers and other social scientists have identified a range of factors that help explain this historically unprecedented event, which is affecting most of the world. Chief amongst these are the profoundly transformative effects of modernisation on feudal, traditional and tribal societies, including urbanisation, industrialisation, education and literacy, greater female workforce participation, improved health care, family planning, higher ages at marriage, and more frequent divorce.

The ultimate demographic effect of these multiple factors was obscured by the moral panic generated around the spectre of “the population bomb” that became widespread in the latter half of the twentieth century. People focused only on the sudden growth of the global population. Various alarmists, such as Paul Ehrlich, insisted in the 1960s that this was out of control, demanded “zero population growth”, and ignored countervailing forces that are now becoming obvious. Indeed, according to Goldman’s analysis, the long-term demographic projections now reveal that the “bulge in world population” that excited Ehrlich and many others was “a one-off event in human history, not the harbinger of environmental doom”. It was an effect produced by the fact that death rates declined rapidly under the impact of modernisation, while birth rates fell much more gradually, causing “a blip in the statistics [that] is about to fade in the rearview mirror”. While global population is set to peak at about 8 billion around 2050 it will then decline precipitously by perhaps 2 billion over the following fifty years, leaving behind a smaller, much older global population, the effects of which will reverberate over the following century.

However, by themselves, Goldman insists, these factors fail to tell the whole story. To the processes of modernisation just noted must be added the profound impact of religion and secularisation, interacting in complex and previously misunderstood ways within societies. Secularisation, it appears, promotes infertility. As secularisation promotes and facilitates the supremacy of individual choice regarding reproduction within previously traditional societies it activates a “demographic contradiction—individualism leading to the choice not to reproduce—[that] may well be the agent that destroys” those societies, as the sociologist Eric Kaufmann suggests in Shall the Religious Inherit the Earth? (2010).

This is not an argument against the liberalisation of tradition-bound societies or for the artificial preservation of obviously non-viable tribal communities. Rather, it is part of Goldman’s case that such liberalisation can have devastating demographic effects that can only be comprehended if adequate attention is given to the spiritual dimensions of human reproduction, and such attention has not been paid by most of the prominent commentators in the field. He believes that “secularism in all its forms fails to address the most fundamental human need”—the deeply embedded human desire to achieve some form of immortality for themselves and their loved ones. The world that secularism offers is a purely immanent world of the here-and-now, stripped of any sense of the transcendent or the eternal. It appears that people are increasingly choosing not to bring new life into such a world.

Religions, on the other hand, in their different ways, “offer the individual the means to transcend mortality, to survive the fragility of a mortal existence”. Life is experienced as a journey full of challenges, joys and disappointments, and new life is embraced as part of a shared voyage through various stages that ultimately stretch beyond this world. Goldman recognises that such claims will mean little to convinced secularists, and that communicating the existential force of religious faith to such persons would be akin to “describing being in love to someone who never has been in love”.

For example, traditional political science, Goldman points out, regards religion as just another belief system, an ideology like communism or fascism, and is therefore unable fully to comprehend the existential grip that the longing for some form of immortality has on human consciousness. Nonetheless, without a comprehension of the power of this spiritual force in human societies, Goldman believes it will be impossible to understand how entire societies can lose faith in the future, turn away from having children and choose instead to accept oblivion. For example, across a range of modern societies the lowest fertility rates in the industrial world are now found in the atheistic former Iron Curtain states of Eastern Europe, while the highest rates are registered in America and Israel, where religion continues to play a major role in people’s lives.

This is not because Americans in general have more children, but because Americans of faith continue to have many children and they constitute a much larger proportion of the overall American population than in any other society that has passed through the processes of modernisation. For example, Goldman cites a 2002 survey that showed that 59 per cent of Americans claimed that religion was important to them, compared to 11 per cent in France, 21 per cent in Germany, 27 per cent in Italy, and 36 per cent in Poland. Another showed that one in two American women of child-bearing age said that religion is “very important” to them, compared with less than one in six European women. Ultimately, religious adherents have more children than others, and far more Americans adhere to their faith than Europeans, Japanese or Russians, among others, including Australia.

Islam is not immune to this process of waxing secularity and waning religiosity. Contrary to the impression confected in the West, Islam is not at all a monolithic edifice of the faithful. Indeed, fundamentalism, with its frenzied re-assertion of archaic religious dogmas, has been only the most recent ideology adopted over the past century as Muslims search for a viable perspective on the processes of modernisation that are engulfing their traditional social structures. In Goldman’s view:

demographic winter arises from a crisis of faith, in the West as well as the Islamic world. In many respects the demographic tailspin of Muslim countries repeats a well-studied pattern in the West: as traditional society gives way to modernity, faith and fertility vanish together.

Consequently, the so-called “Islamic Reformation” being promoted by Tariq Ramadan, other Islamist ideologues, and Western academics, with its alleged return to traditional Muslim faithfulness, is being exposed as a mirage by the actual behaviour of the masses of young Muslims of child-bearing age: “the vast majority of educated young Muslims are alienated from the traditional Islamic culture of previous generations and rebel quietly against the Islamists’ attempt to re-impose it by force. They have voted with their wombs”, Goldman observes.

According to this analysis, the recent recrudescence of medieval Muslim fundamentalism is a desperate and increasingly hysterical response to the demographic threat, obscuring the spiritual collapse of contemporary Islam that is actually under way. The violent aggression of Islamist and Salafist groups, their fanatical self-assertiveness, their primitive attitudes towards women, and their xenophobic behaviour towards all other faiths and cultures have conjured up a “facade of religious authority [that] seems unbroken in most of the Muslim world”, when in fact, “behind the facade … the deterioration of traditional society hollows out religious faith”.

Therefore, despite Iran’s pretensions to being an observant Islamic theocracy, surveys indicate that there are lower rates of mosque attendance there than in any other Muslim country except Turkey, which has been a militantly secular state for most of the past ninety years. Only around 2 per cent of Iranian adults regularly attend Friday prayers. Meanwhile, as Goldman points out, “under the facade of radical Islam, Iran suffers from an eruption of social pathologies such as drug addiction and prostitution on a scale much worse than anything observed in the West”. There may be as many as 5 million hard-drug users, while in Tehran alone there are some 300,000 prostitutes, and this figure doesn’t include women engaging regularly in “temporary marriages”, which conveniently last from five to twenty-four hours and are legally sanctioned by Shi’ite Islam. There is also a flourishing international trade in Iranian women, who find themselves being trafficked to the Gulf States, Europe and Japan. “It appears that Islamic theocracy promotes rather than represses social decay,” Goldman points out. The Islamo-fascist facade serves to hide a disintegrating civil society.

Civil society is a central concept in Goldman’s analysis, as it is within this realm that family life unfolds and is sustained. It is also a realm whose historical vibrancy characterises Western societies, while its absence or rudimentary level of development is a central feature of Muslim societies. Here he derives insights from St Augustine in The City of God, which, he emphasises, was written as the Roman empire collapsed through demographic decline, and the author awaited the rampaging barbarians that would soon lay waste to his civilisation. Goldman contrasts Augustine’s recognition of the role of civil society with the focus on the state by the Roman philosopher Cicero: Augustine “looked through the state to the underlying civil society, and understood civil society as a congregation—a body bound together by common loves, as opposed to Cicero’s state founded only on common interests”.

It is the strength and vibrancy of civil society, bound together at the most intimate personal levels, that ensure the continuity of a civilisation, and not the exercise of power by the state in the pursuit of its own interests, whatever they might be and however much it may claim to rule on behalf of the people. A theocracy such as that of Iran, despite its pretensions to be implementing traditional religious values, actually operates like any other totalitarian or statist regime, destroying civil society by its domineering presence in the life of the people, and suppressing, suffocating and dissipating the very social and cultural dynamism that any civilisation depends upon if it is going to survive and flourish. (An excellent description of how this process destroyed civil society under the highly intrusive rule of the Soviet communist state is contained in Orlando Figes, The Whisperers: Private Life in Stalin’s Russia, 2007.)

Goldman’s analysis leads to what he calls a position of “Augustinian realism” in foreign policy, which focuses on those societies that both preserve civil society and nurture within it the values that resonate within American civil society. The calculation here is simple: the principle that “civil society precedes the character of a nation [means that while America] can ally with, cajole, or even crush other states … it cannot change the character of their civil society”, and consequently it is a chimerical pursuit to attempt to do so by military intervention or massive amounts of foreign aid.

It follows therefore that America should not waste its time seeking to democratically transform intrinsically ruinous states, but should focus instead on pursuing and nurturing alliances with “people who are linked to [American] civil society—our mother country England, for example, as well as the Christians in the global South”, including Australia. This approach also entails a continuing alliance with Israel, which, along with America, possesses both a dynamic civil society and a substantial fertility rate—indeed it exceeds that of America a time at a time when the Israeli people face a continuing and escalating threat to their very existence.

Australia is in a unique position in this scenario. As a Western society we possess not only a dynamic civil society like that of America but also share similar political, economic, cultural and social institutions and values. On the other hand, Australia is a far more secular society than America (and indeed much of its political, cultural and academic elites are militantly secularist), and it exhibits some of the demographic dynamics that will lead soon to the perhaps terminal decline of Europe. These tendencies have been partially offset by a sustained program of immigration from many parts of the world, but we are also in close proximity to populous Muslim countries and are vulnerable to uncontrolled and illegal immigration from that region. This could easily undermine the success of our immigration program, especially if separatist Muslim ghettoes and “no-go areas” are tolerated, as they have been in Europe and especially in Britain.

According to standard ABS projections, Australia’s population will increase to between 31 million and 43 million by mid-century, depending on assumptions relating to fertility rates, life expectancy and net immigration. In the second half of the century the types of dynamics highlighted by Goldman increasingly take effect and the projections diverge, varying between 34 million and 64 million people. The lower projections are those preferred by much of the Labor Party, the Greens, the environmental movement, and urban and academic elites who are obsessed with “sustainability” and apparently comfortable with an Australia sparsely populated by an aged, enfeebled and increasingly vulnerable population sustained by a failing welfare state, and facing a world in demographic crisis and economic and political turmoil.

The alternative is to embrace very high levels of population growth and the economic dynamism that goes with it. Quite apart from the resources boom and the need to upgrade Australia’s infrastructure on a national scale, there are also major opportunities for development in northern Australia, capitalising on its vast fertile lands and the gigantic rainfall that the region enjoys but which remains largely unharvested, for consumption, irrigation, and diversion into the Murray-Darling system, and for other purposes including hydro-electricity. Visions of Australia serving as the “food bowl of Asia” have a great deal to commend them, especially while the world passes through the demographic catastrophe that appears certain to occur later this century.

It is a point not made by Goldman, but Australia shares with America one other vital characteristic—both nations have been frontier societies, surging ahead over the past two centuries with economic and social development on a continental scale. For generations both countries have been able to attract settlers and immigrants who have built their lives in our respective societies through determination and perseverance, and a desire to hand something on to their children.

This frontier ethos and nation-building spirit—“the Australian Legend”—remains a dynamic force in our country and explains the ease with which our society remains cohesive despite the fact that some 24 per cent of its population is overseas-born (a far greater proportion than any other country, and twice that of Europe, which is imploding as we have seen). Now, perhaps more than ever, it is the time to re-activate, re-embrace and promote that spirit, as we confront the colossal challenges that the demographic revolution of the twenty-first century will place before us.

The Skeptic’s Case

The Skeptic’s Case

By David Evans

We check the main predictions of the climate models against the best and latest data. Fortunately the climate models got all their major predictions wrong. Why? Every serious skeptical scientist has been consistently saying essentially the same thing for over 20 years, yet most people have never heard the message. Here it is, put simply enough for any lay reader willing to pay attention.

What the Government Climate Scientists Say

image

The climate models. If the CO2 level doubles (as it is on course to do by about 2070 to 2100), the climate models estimate the temperature increase due to that extra CO2 will be about 1.1C � 3 = 3.3C.[1]

The direct effect of CO2 is well-established physics, based on laboratory results, and known for over a century.[2]

Feedbacks are due to the ways the Earth reacts to the direct warming effect of the CO2. The threefold amplification by feedbacks is based on the assumption, or guess, made around 1980, that more warming due to CO2 will cause more evaporation from the oceans and that this extra water vapor will in turn lead to even more heat trapping because water vapor is the main greenhouse gas. And extra heat will cause even more evaporation, and so on. This amplification is built into all the climate models.[3] The amount of amplification is estimated by assuming that nearly all the industrial-age warming is due to our CO2.

The government climate scientists and the media often tell us about the direct effect of the CO2, but rarely admit that two-thirds of their projected temperature increases are due to amplification by feedbacks.

What the Skeptics Say

image
Figure 2

The skeptic’s view. If the CO2 level doubles, skeptics estimates that the temperature increase due to that extra CO2 will be about 1.1C � 0.5 ≈ 0.6C.[4]

The serious skeptical scientists have always agreed with the government climate scientists about the direct effect of CO2. The argument is entirely about the feedbacks.

The feedbacks dampen or reduce the direct effect of the extra CO2, cutting it roughly in half.[5] The main feedbacks involve evaporation, water vapor, and clouds. In particular, water vapor condenses into clouds, so extra water vapor due to the direct warming effect of extra CO2 will cause extra clouds, which reflect sunlight back out to space and cool the earth, thereby reducing the overall warming.

There are literally thousands of feedbacks, each of which either reinforces or opposes the direct-warming effect of the extra CO2. Almost every long-lived system is governed by net feedback that dampens its response to a perturbation. If a system instead reacts to a perturbation by amplifying it, the system is likely to reach a tipping point and become unstable (like the electronic squeal that erupts when a microphone gets too close to its speakers). The earth’s climate is long-lived and stable - it has never gone into runaway greenhouse, unlike Venus - which strongly suggests that the feedbacks dampen temperature perturbations such as that from extra CO2.

What the Data Says

The climate models have been essentially the same for 30 years now, maintaining roughly the same sensitivity to extra CO2 even while they got more detailed with more computer power.

� How well have the climate models predicted the temperature?

� Does the data better support the climate models or the skeptic’s view?
Air Temperatures

One of the earliest and most important predictions was presented to the US Congress in 1988 by Dr James Hansen, the “father of global warming”:

image
Figure 3. Hansen’s predictions to the US Congress in 1988,[6] compared to the subsequent temperatures as measured by NASA satellites.[7]

Hansen’s climate model clearly exaggerated future temperature rises.

In particular, his climate model predicted that if human CO2 emissions were cut back drastically starting in 1988, such that by year 2000 the CO2 level was not rising at all, we would get his scenario C. But in reality the temperature did not even rise this much, even though our CO2 emissions strongly increased � which suggests that the climate models greatly overestimate the effect of CO2 emissions.

A more considered prediction by the climate models was made in 1990 in the IPCC’s First Assessment Report:[8]

image
Figure 4 Predictions of the IPCC’s First Assessment Report in 1990, compared to the subsequent temperatures as measured by NASA satellites.

It’s 20 years now, and the average rate of increase in reality is below the lowest trend in the range predicted by the IPCC.
Ocean Temperatures

The oceans hold the vast bulk of the heat in the climate system. We’ve only been measuring ocean temperature properly since mid-2003, when the Argo system became operational.[9][10] In Argo, a buoy duck dives down to a depth of 2,000 meters, measures temperatures as it very slowly ascends, then radios the results back to headquarters via satellite. Over 3,000 Argo buoys constantly patrol all the oceans of the world.

image
Figure 5. Climate model predictions of ocean temperature,[11] versus the measurements by Argo.[12] The unit of the vertical axis is 10^22 Joules (about 0.01C).

The ocean temperature has been basically flat since we started measuring it properly, and not warming as quickly as the climate models predict.
Atmospheric Hotspot

The climate models predict a particular pattern of atmospheric warming during periods of global warming; the most prominent change they predict is a warming in the tropics about 10 km up, the “hotspot.”

The hotspot is the sign of the amplification in their theory (see figure 1). The theory says the hotspot is caused by extra evaporation, and by extra water vapor pushing the warmer, wetter lower troposphere up into volume previously occupied by cool dry air. The presence of a hotspot would indicate amplification is occurring, and vice versa.

We have been measuring atmospheric temperatures with weather balloons since the 1960s. Millions of weather balloons have built up a good picture of atmospheric temperatures over the last few decades, including the warming period from the late 1970s to the late ‘90s. This important and pivotal data was not released publicly by the climate establishment until 2006, and then in an obscure place.[13] Here it is:

image
Figure 6. On the left is the data collected by millions of weather balloons.[14] On the right is what the climate models say was happening.[15] The theory (as per the climate models) is incompatible with the observations. In both diagrams the horizontal axis shows latitude, and the right vertical axis shows height in kilometers.

In reality there was no hotspot, not even a small one. So in reality there is no amplification - the amplification shown in figure 1 does not exist.[16]

Outgoing Radiation

image

The climate models predict that when the surface of the earth warms, less heat is radiated from the earth into space (on a weekly or monthly time scale). This is because, according to the theory, the warmer surface causes more evaporation and thus there is more heat-trapping water vapor. This is the heat-trapping mechanism that is responsible for the assumed amplification in figure 1.

Satellites have been measuring the radiation emitted from the earth for the last two decades. A major study has linked the changes in temperature on the earth’s surface with the changes in the outgoing radiation. Here are the results:

Outgoing radiation from earth (vertical axis) against sea-surface temperature (horizontal), as measured by the ERBE satellites (upper-left graph) and as “predicted” by 11 climate models (the other graphs).[17] Notice that the slopes of the graphs for the climate models are opposite to the slope of the graph for the observed data.

This shows that in reality the earth gives off more heat when its surface is warmer. This is the opposite of what the climate models predict. This shows that the climate models trap heat too aggressively, and that their assumed amplification shown in figure 1 does not exist.

Conclusions

All the data here is impeccably sourced - satellites, Argo, and weather balloons.[18]

The air and ocean temperature data shows that the climate models overestimate temperature rises. The climate establishment suggest that cooling due to undetected aerosols might be responsible for the failure of the models to date, but this excuse is wearing thin - it continues not to warm as much as they said it would, or in the way they said it would. On the other hand, the rise in air temperature has been greater than the skeptics say could be due to CO2. The skeptic’s excuse is that the rise is mainly due to other forces - and they point out that the world has been in a fairly steady warming trend of 0.5C per century since 1680 (with alternating ~30 year periods of warming and mild cooling) where as the vast bulk of all human CO2 emissions have been after 1945.

We’ve checked all the main predictions of the climate models against the best data:

Test

Climate Models

Air temperatures from 1988:

Overestimated rise, even if CO2 is drastically cut

Air temperatures from 1990

Overestimated trend rise

Ocean temperatures from 2003

Overestimated trend rise greatly

Atmospheric hotspot

Completely missing → no amplification

Outgoing radiation

Opposite to reality → no amplification

The climate models get them all wrong. The missing hotspot and outgoing radiation data both, independently, prove that the amplification in the climate models is not present. Without the amplification, the climate model temperature predictions would be cut by at least two-thirds, which would explain why they overestimated the recent air and ocean temperature increases. Therefore,

* The climate models are fundamentally flawed. Their assumed threefold amplification by feedbacks does not in fact exist.

* The climate models overestimate temperature rises due to CO2 by at least a factor of three.

* The skeptical view is compatible with the data.

Some Political Points

The data presented here is impeccably sourced, very relevant, publicly available, and from our best instruments. Yet it never appears in the mainstream media � have you ever seen anything like any of the figures here in the mainstream media? That alone tells you that the “debate” is about politics and power, and not about science or truth.

This is an unusual political issue, because there is a right and a wrong answer, and everyone will know which it is eventually. People are going ahead and emitting CO2 anyway, so we are doing the experiment: either the world heats up by several degrees by 2050 or so, or it doesn’t.

Notice that the skeptics agree with the government climate scientists about the direct effect of CO2; they just disagree about the feedbacks. The climate debate is all about the feedbacks; everything else is merely a sideshow. Yet hardly anyone knows that. The government climate scientists and the mainstream media have framed the debate in terms of the direct effect of CO2 and sideshows such as arctic ice, bad weather, or psychology. They almost never mention the feedbacks. Why is that? Who has the power to make that happen?

Dr. David M.W. Evans consulted full time for the Australian Greenhouse Office (now the Department of Climate Change) from 1999 to 2005, and part time 2008 to 2010, modeling Australia�s carbon in plants, debris, mulch, soils, and forestry and agricultural products. Evans is a mathematician and engineer, with six university degrees including a PhD from Stanford University in electrical engineering. The area of human endeavor with the most experience and sophistication in dealing with feedbacks and analyzing complex systems is electrical engineering, and the most crucial and disputed aspects of understanding the climate system are the feedbacks. The evidence supporting the idea that CO2 emissions were the main cause of global warming reversed itself from 1998 to 2006, causing Evans to move from being a warmist to a skeptic.

Same Sex Marriage

Towards the end of all wedlock

IF you are fed up with hearing about gay marriage, then join the club.

The results of the most recent poll about this contentious and important issue shows that while a slim majority of Australians support the concept, nobody rates it very highly as an issue. Even Get Up!, the main flag waver for gay marriage, says it is at the bottom of the list of concerns for Australians already burdened with a failing health system, a carbon tax and a rash of industrial action. By taking on this issue at the behest of the Greens, the Labor Party has not only made life difficult for Julia Gillard. It has betrayed its promise to the electorate not to introduce gay marriage, the declaration Nicola Roxon, as opposition legal affairs spokeswoman, made in 2003 at the national marriage forum at Parliament House.

The Prime Minister has decided on a conscience vote, a clever move. It puts Tony Abbott on the spot. There could well be enough wet Liberals voting for gay marriage to get it through in the lower house, although whether it would pass the Senate, which is more conservative, is uncertain.

These questions are the kinds of things that we normally do regard as conscience issues. And eventually, if it is put enough times and enough people change their vote, it would probably get through. It is called legislation by fatigue.

One element of this issue that has been touched on only lightly is the so-called slippery slope. There usually is one on these matters, and fatigue with the issue often leads directly down the slope. So abortion as last resort has turned into abortion on demand and to term, and in-vitro fertilisation as an aid for infertile married couples has become IVF for any geriatric mother or her surrogate.

So it is with same-sex unions. Abolition of the punitive legal barriers that dogged homosexuals' lives in my youth has morphed into a general acceptance of homosexuality as no more than a type of sexual left-handedness. This has allowed homosexuals to manufacture families whose children have birth certificates that lie about their parentage, which in turn has become a push to legalise and give the same status to homosexual unions as marriages - even though legal heterosexual marriage exists and has status because only heterosexual relationships can produce children.

This incremental deconstruction of the natural, social norms of sexual relations is the stated gender policy of the Greens. They have all but succeeded. The public may be apathetic, but in the long run Australians should be aware of the dangerous implications that could limit our basic freedoms.

Where Canada goes we tend to follow. This week in that hotbed of gender deconstruction, where kids can have three parents and gender-neutral means just that, an attempt to overturn that country's laws against polygamy have been challenged. Ironically, for something that is very regressive, punitive for women and children, and generally regarded as heralding the acceptance of sharia to govern family law, an unsuccessful move to introduce polygamy in Canada has come directly because of the legislation on same-sex marriage. In same-sex marriage the argument was based on discrimination on the basis of sexual orientation; with polygamy it's based on breach of freedom of religion, which is an even more protected right.

At the heart of the legal arguments was the slippery-slope argument that Canadians (and Americans) opposed to same-sex marriage have long asserted. The polygamists argued Canadian law condoned "casual group sex, but criminalises committed, group relationships . . . marriage is no longer only between a man and a woman, adultery has never been a criminal offence and group sex and partner-swapping were legalised in 2005 following a Supreme Court of Canada ruling".

If polygamy is ever introduced it could affect pension law, survivor rights to pensions and health benefits. It could also affect immigration policies on family reunification if a person has more than one spouse. This time Canada recognised that just as the 2004 same-sex marriage law resulted in a move away from the traditional definition of marriage, striking down the law also could significantly further affect the way Canadians define the institution of marriage as monogamous, because polygamy could lead to polyamory or no legal marriage.

And the beginning of the end of marriage is a situation that would further harm children. That is one reason this move did not succeed. In his opening statement, the lawyer for the polygamists boldly stated that "polygamy is not inherently harmful to children", but he cited no evidence to support that. Interestingly, homosexual activists routinely declare that same-sex partnerships are not harmful to children, even though there is plenty of evidence to the contrary.

Same-sex marriage is a deconstruction of the natural heterosexual family structure; hence it is dangerous in itself.

But for those opposed to gay marriage the real line in the sand is that gay marriage is being pushed as a way of thought control. By legally normalising homosexuality beyond mere social acceptance, many groups, including Catholic educators, worry that acceptance of homosexual partnerships will be reinforced by punitive legal sanctions, which would shut off all debate on homosexuality as a moral issue and effectively limit our already limited freedom of speech on the issue.

Witness what happened to general practitioner David van Gend, who was dragged before the anti-discrimination police when he argued against homosexual families bringing up children.

If you don't believe me, look at what has happened in Massachusetts in the US since gay marriage became legal there. It has to be reinforced in schools and it has put Catholic schools in a particular bind. In this country, Green pro-gay lobbyists make no secret of the fact they would like to overturn exceptions to the anti-discrimination laws to target the Catholic school system and what is taught about human sexuality. This threat to freedom of speech is the real dangerous end of the slippery slope. One would hope those wrestling with their consciences would give pause to consider this.

There is a veritable Luna Park, or lunatic park, of slippery slopes out there.

Optimism and doomsayers


Why rational optimism beats ephemeral happiness

Janet Albrechtson
The Australian

FASHIONABLE academics, activists and politicians presume to tell us how miserable we are to justify their notions about the sunny path to human happiness.

The British Office for National Statistics now asks people whether they are happy. British Prime Minister David Cameron wants to draw up a happiness index to govern policy, while a group called the Action for Happiness, launched in April by the Dalai Lama, has set down its own rules for riding the road to happiness. Bhutan, we are told, is the happiest place on earth, which is curious given that hordes of refugees are not crossing the borders into the small landlocked kingdom. These clever chaps promise to make us happy if only we would follow their clever ideas

Here's a better idea. Rational optimism beats ephemeral happiness. While there is something familiarly depressing about a grand leader promising to make us happy - Stalin did it, so did Hitler - the best form of contentment comes from learning some history.

Enter Matt Ridley. On a grey, wintry Sydney morning last week, the author of The Rational Optimist: How Prosperity Evolves delivered a fast-paced, fact-laden history lesson about the extraordinary trajectory of mankind.

Speaking at the Centre for Independent Studies, Ridley quoted British historian Thomas Babington Macaulay, who once asked: "On what principle is it that when we see nothing but improvement behind us, we are to expect nothing but deterioration before us?" That was in 1830, even before the industrial revolution delivered vast improvements to the way we live. Two centuries later, after even greater innovation and progress, it is passing strange that rational optimism remains such a rarity.

Asked about this conundrum, Ridley points to the intelligentsia. Calamitous predictions about the future, not calm reasoning about the past, sell books and sustain careers. And "there's more of the intelligentsia around now so you hear more from them". The "apocaholics" predict doom and gloom from Malthusian population explosions, AIDS epidemics, bird flu pandemics, peak oil problems, depleting ozone layers, acid rains, deforestation, urbanisation, and over-consumption. The list is long.

By contrast, Ridley, a lanky, dry-witted Brit, an Oxford-educated scientist, former editor at The Economist, author of a string of books about evolution and all-round polymath, takes the rational road. Looking at the past to predict the future, he finds a rising line of glorious human triumph.

Start with one simple measurement. Appropriately fitted out with a CIS tie covered in small light bulbs, Ridley asks how long you have to work today to earn an hour of reading light. On an average wage today, half a second of work will pay for an hour of light. In 1950, the average wage earner worked eight seconds to run a conventional filament lamp; in 1880, 15 seconds of work was needed for a kerosene lamp; and more than six hours of work for an hour of light by tallow candle in the 1800s. In 1750BC, your average ancient Babylonian needed to work more than 50 hours to get an hour of light from a sesame oil lamp. That 43,200-fold improvement, says Ridley, signifies "the currency that counts, your time".

By any other measure, too, we are also better off. The world population has multiplied six times since 1800, yet on average we live twice as long and, in real terms, earn nine times more money.

Even in the space of 50 years, from 1955 to 2005, as Ridley writes in his book, "the average human being on Planet Earth earned nearly three times as much money (corrected for inflation), ate one-third more calories and could expect to live one-third longer. She was less likely to die as a result of war, murder, childbirth, accidents, tornadoes, flooding, famine, whooping cough, tuberculosis, malaria, diphtheria, typhus, typhoid, measles, smallpox, scurvy or polio. She was less likely, at any given age, to get cancer, heart disease or a stroke.

"She was more likely to be literate . . . to have finished school . . . own a telephone, a flush toilet, a refrigerator" and so on and so forth.

All this when the world population more than doubled. As Ridley notes, the UN estimates that poverty was reduced more in the past 50 years than in the previous five centuries.

Anyone can recount the facts of human progress, even the doomsayers were they more curious. What marks out Ridley is his explanation of our success. After looking back at thousands of years of evolution, natural selection and culture, he finds that we started to prosper not when our individual brains grew in size - Neanderthals had bigger brains that we do - but when our collective brain grew. Ridley traces the start of our extraordinary cultural revolution to a time, about 100,000 years ago, when, unlike other species, we started to exchange goods and ideas with people beyond our own communities.

"At some point in human history, ideas began to meet and mate, and to have sex with each other." Culture quickly became cumulative. "Exchange is to cultural evolution as sex is to biological evolution," writes Ridley.

By a process similar to natural selection, sound ideas triumphed and will continue to triumph so long as we enable them to "meet and mate". Looking back on history, Ridley rediscovers the ideas of Adam Smith and Friedrich von Hayek, and adds evolutionary biology to explain why homo sapiens progresses at a much faster rate than any other species. Constant innovation comes from a free market for ideas - not to mention goods and services.

Look at your computer mouse, says Ridley. No single person knows how to make one. The factory worker who assembled it didn't drill for oil to make the plastic. "At some point, human intelligence became collective and cumulative in a way that happened to no other species."

That's Ridley's reason for being a rational optimist. At every juncture, humans have adapted, innovated and changed in the face of dire predictions. Prosperity depends on a bottom-up process from people learning from and sharing with others.

No wonder the happiness gurus, eager to impose their idea of happiness upon us, eschew history. As Ridley explores in his 400-page plus race through history from the Stone Age to the 21st century, government departments and bureaucracies, whether we're talking Egyptian pharaohs or British Rail, didn't drive innovation. People do.

And consider how technology has ramped up the pace at which people can share with and learn from others. Ridley, the rational optimist, predicts innovation will accelerate at a much faster pace than ever. Which is happy news if only we can steer clear of the Scylla and Charybdis of modernity, the imposers of happiness who favour top-down diktats about happiness and the apocaholics who shudder at technology, scoff at globalisation and regard free trade in anything - even ideas - as an abomination.

The Truth About Greenhouse Gases

Article in First things http://www.firstthings.com/article/2011/05/the-truth-about-greenhouse-gases

The Truth About Greenhouse Gases
The dubious science of the climate crusaders.

The object of the Author in the following pages has been to collect the most remarkable instances of those moral epidemics which have been excited, sometimes by one cause and sometimes by another, and to show how easily the masses have been led astray, and how imitative and gregarious men are, even in their infatuations and crimes,” wrote Charles Mackay in the preface to the first edition of his Extraordinary Popular Delusions and the Madness of Crowds. I want to discuss a contemporary moral epidemic: the notion that increasing atmospheric concentrations of greenhouse gases, notably carbon dioxide, will have disastrous consequences for mankind and for the planet. The “climate crusade” is one characterized by true believers, opportunists, cynics, money-hungry governments, manipulators of various types—even children’s crusades—all based on contested science and dubious claims.

I am a strong supporter of a clean environment. We need to be vigilant to keep our land, air, and waters free of real pollution, particulates, heavy metals, and pathogens, but carbon dioxide (CO2 ) is not one of these pollutants. Carbon is the stuff of life. Our bodies are made of carbon. A normal human exhales around 1 kg of CO2 (the simplest chemically stable molecule of carbon in the earth’s atmosphere) per day. Before the industrial period, the concentration of CO2 in the atmosphere was 270 ppm. At the present time, the concentration is about 390 ppm, 0.039 percent of all atmospheric molecules and less than 1 percent of that in our breath. About fifty million years ago, a brief moment in the long history of life on earth, geological evidence indicates, CO2 levels were several thousand ppm, much higher than now. And life flourished abundantly.

Now the Environmental Protection Agency wants to regulate atmospheric CO2 as a “pollutant.” According to my Webster’s New Collegiate Dictionary, to pollute is “to make or render unclean, to defile, to desecrate, to profane.” By breathing are we rendering the air unclean, defiling or desecrating it? Efforts are underway to remedy the old-fashioned, restrictive definition of pollution. The current Wikipedia entry on air pollution, for example, now asserts that pollution includes: “carbon dioxide (CO2)—a colorless, odorless, non-toxic greenhouse gas associated with ocean acidification, emitted from sources such as combustion, cement production, and respiration.”

As far as green plants are concerned, CO2 is not a pollutant, but part of their daily bread—like water, sunlight, nitrogen, and other essential elements. Most green plants evolved at CO2 levels of several thousand ppm, many times higher than now. Plants grow better and have better flowers and fruit at higher levels. Commercial greenhouse operators recognize this when they artificially increase the concentrations inside their greenhouses to over 1000 ppm.

Wallis Simpson, the woman for whom King Edward VIII renounced the British throne, supposedly said, “A woman can’t be too rich or too thin.” But in reality, you can get too much or too little of a good thing. Whether we should be glad or worried about increasing levels of CO2 depends on quantitative numbers, not just qualitative considerations.

How close is the current atmosphere to the upper or lower limit for CO2? Did we have just the right concentration at the preindustrial level of 270 ppm? Reading breathless media reports about CO2 “pollution” and about minimizing our carbon footprints, one might think that the earth cannot have too little CO2, as Simpson thought one couldn’t be too thin—a view which was also overstated, as we have seen from the sad effects of anorexia in so many young women. Various geo-engineering schemes are being discussed for scrubbing CO2 from the air and cleansing the atmosphere of the “pollutant.” There is no lower limit for human beings, but there is for human life. We would be perfectly healthy in a world with little or no atmospheric CO2—except that we would have nothing to eat and a few other minor inconveniences, because most plants stop growing if the levels drop much below 150 ppm. If we want to continue to be fed and clothed by the products of green plants, we can have too little CO2.

The minimum acceptable value for plants is not that much below the 270 ppm preindustrial value. It is possible that this is not enough, that we are better off with our current level, and would be better off with more still. There is evidence that California orange groves are about 30 percent more productive today than they were 150 years ago because of the increase of atmospheric CO2.

Although human beings and many other animals would do well with no CO2 at all in the air, there is an upper limit that we can tolerate. Inhaling air with a concentration of a few percent, similar to the concentration of the air we exhale, hinders the diffusional exchange of CO2 between the blood and gas in the lung. Both the United States Navy (for submariners) and nasa (for astronauts) have performed extensive studies of human tolerance to CO2. As a result of these studies, the Navy recommends an upper limit of about 8000 ppm for cruises of ninety days, and nasa recommends an upper limit of 5000 ppm for missions of one thousand days, both assuming a total pressure of one atmosphere. Higher levels are acceptable for missions of only a few days.

We conclude that atmospheric CO2 levels should be above 150 ppm to avoid harming green plants and below about 5000 ppm to avoid harming people. That is a very wide range, and our atmosphere is much closer to the lower end than to the upper end. The current rate of burning fossil fuels adds about 2 ppm per year to the atmosphere, so that getting from the current level to 1000 ppm would take about 300 years—and 1000 ppm is still less than what most plants would prefer, and much less than either the nasa or the Navy limit for human beings.

Yet there are strident calls for immediately stopping further increases in CO2 levels and reducing the current level. As we have discussed, animals would not even notice a doubling of CO2 and plants would love it. The supposed reason for limiting it is to stop global warming—or, since the predicted warming has failed to be nearly as large as computer models forecast, to stop climate change. Climate change itself has been embarrassingly uneventful, so another rationale for reducing CO2 is now promoted: to stop the hypothetical increase of extreme climate events like hurricanes or tornados. But this does not necessarily follow. The frequency of extreme events has either not changed or has decreased in the 150 years that CO2 levels have increased from 270 to 390 ppm.

Let me turn to some of the problems the non-pollutant CO2 is supposed to cause. More CO2 is supposed to cause flooded cities, parched agriculture, tropical diseases in Alaska, etc., and even an epidemic of kidney stones. It does indeed cause some warming of our planet, and we should thank Providence for that, because without the greenhouse warming of CO2 and its more potent partners, water vapor and clouds, the earth would be too cold to sustain its current abundance of life.

Other things being equal, more CO2 will cause more warming. The question is how much warming, and whether the increased CO2 and the warming it causes will be good or bad for the planet.

The argument starts something like this. CO2 levels have increased from about 280 ppm to 390 ppm over the past 150 years or so, and the earth has warmed by about 0.8 degree Celsius during that time. Therefore the warming is due to CO2. But correlation is not causation. Roosters crow every morning at sunrise, but that does not mean the rooster caused the sun to rise. The sun will still rise on Monday if you decide to have the rooster for Sunday dinner.

There have been many warmings and coolings in the past when the CO2 levels did not change. A well-known example is the medieval warming, about the year 1000, when the Vikings settled Greenland (when it was green) and wine was exported from England. This warm period was followed by the “little ice age” when the Thames would frequently freeze over during the winter. There is no evidence for significant increase of CO2 in the medieval warm period, nor for a significant decrease at the time of the subsequent little ice age. Documented famines with millions of deaths occurred during the little ice age because the cold weather killed the crops. Since the end of the little ice age, the earth has been warming in fits and starts, and humanity’s quality of life has improved accordingly.

A rare case of good correlation between CO2 levels and temperature is provided by ice-core records of the cycles of glacial and interglacial periods of the last million years of so. But these records show that changes in temperature preceded changes in CO2 levels, so that the levels were an effect of temperature changes. This was probably due to outgassing of CO2 from the warming oceans and the reverse effect when they cooled.

The most recent continental ice sheets began to melt some twenty thousand years ago. During the “Younger Dryas” some 12,000 years ago, the earth very dramatically cooled and warmed by as much as 10 degrees Celsius in fifty years.

The earth’s climate has always been changing. Our present global warming is not at all unusual by the standards of geological history, and it is probably benefiting the biosphere. Indeed, there is very little correlation between the estimates of CO2 and of the earth’s temperature over the past 550 million years (the “Phanerozoic” period). The message is clear that several factors must influence the earth’s temperature, and that while CO2 is one of these factors, it is seldom the dominant one. The other factors are not well understood. Plausible candidates are spontaneous variations of the complicated fluid flow patterns in the oceans and atmosphere of the earth—perhaps influenced by continental drift, volcanoes, variations of the earth’s orbital parameters (ellipticity, spin-axis orientation, etc.), asteroid and comet impacts, variations in the sun’s output (not only the visible radiation but the amount of ultraviolet light, and the solar wind with its magnetic field), variations in cosmic rays leading to variations in cloud cover, and other causes.

The existence of the little ice age and the medieval warm period were an embarrassment to the global-warming establishment, because they showed that the current warming is almost indistinguishable from previous warmings and coolings that had nothing to do with burning fossil fuel. The organization charged with producing scientific support for the climate change crusade, the Intergovernmental Panel on Climate Change (IPCC), finally found a solution. They rewrote the climate history of the past 1000 years with the celebrated “hockey stick” temperature record.

The first IPCC report, issued in 1990, showed both the medieval warm period and the little ice age very clearly. In the IPCC’s 2001 report was a graph that purported to show the earth’s mean temperature since the year 1000. A yet more extreme version of the hockey stick graph made the cover of the Fiftieth Anniversary Report of the United Nation’s World Meteorological Organization. To the surprise of everyone who knew about the strong evidence for the little ice age and the medieval climate optimum, the graph showed a nearly constant temperature from the year 1000 until about 150 years ago, when the temperature began to rise abruptly like the blade of a hockey stick. The inference was that this was due to the anthropogenic “pollutant” CO2.

This damnatia memoriae of inconvenient facts was simply expunged from the 2001 IPCC report, much as Trotsky and Yezhov were removed from Stalin’s photographs by dark-room specialists in the later years of the dictator’s reign. There was no explanation of why both the medieval warm period and the little ice age, very clearly shown in the 1990 report, had simply disappeared eleven years later.

The IPCC and its worshipful supporters did their best to promote the hockey-stick temperature curve. But as John Adams remarked, “Facts are stubborn things, and whatever may be our wishes, our inclinations, or the dictates of our passion, they cannot alter the state of facts and evidence.” The hockey-stick curve caught the attention of two Canadians, Steve McIntyre, a mining consultant, and an academic statistician, Ross McKitrick. As they began to look more carefully at the original data—much of it from tree rings—and at the analysis that led to the hockey stick, they became more and more puzzled. By hard, remarkably detailed, and persistent work over many years, consistently frustrated in their efforts to obtain original data and data-analysis methods, they showed that the hockey stick was not supported by observational data. An excellent, recent history of this episode is A. W. Montford’s The Hockey Stick Illusion.

About the time of the Copenhagen Climate Conference in the fall of 2009, another nasty thing happened to the global-warming establishment. A Russian server released large numbers of e-mails and other files from computers of the Climate Research Unit (CRU) of the University of East Anglia. Among the files released were e-mails between members of the power structure of the climate crusade, “the team.” These files were, or should have been, very embarrassing to their senders and recipients. A senior scientist from CRU wrote, for example: “PS, I’m getting hassled by a couple of people to release the CRU station temperature data. Don’t any of you three tell anybody that the UK has a freedom of information act.”

A traditional way to maintain integrity in science is through peer review, the anonymous examination of a scientific paper by qualified, competing scientists before publication. In a responsible peer review, the authors may be required to make substantial revisions to correct any flaws in the science or methodology before their paper is published. But peer review has largely failed in climate science. Global warming alarmists have something like Gadaffi’s initial air superiority over rag-tag opponents in Libya.

Consider this comment from one of the most respected IPCC leaders, as revealed in the CRU e-mails: “I can’t see either of these papers being in the next IPCC report. Kevin and I will keep them out somehow—even if we have to define what the peer-review literature is.” And consider the CRU e-mail comment on a journal that committed the mortal sin of publishing one of the heretical papers: “I think we have to stop considering Climate Research as a legitimate peer-reviewed journal. Perhaps we should encourage our colleagues in the climate research community to no longer submit to, or cite papers in, this journal.” Peer review in climate science means that the “team” recommends publication of each other’s work, and tries to keep any off-message paper from being accepted for publication.

James Madison reminds us in The Federalist Papers that “no man is allowed to be a judge in his own cause, because his interest would certainly bias his judgment, and, not improbably, corrupt his integrity. With equal, nay with greater reason, a body of men are unfit to be both judges and parties at the same time.” Madison goes on to observe that the smaller the community, the more likely that parties and judges will be one and the same.

Let me summarize how the key issues appear to me, a working scientist with a better background than most in the physics of climate. CO2 really is a greenhouse gas and other things being equal, adding the gas to the atmosphere by burning coal, oil, and natural gas will modestly increase the surface temperature of the earth. Other things being equal, doubling the CO2 concentration, from our current 390 ppm to 780 ppm will directly cause about 1 degree Celsius in warming. At the current rate of CO2 increase in the atmosphere—about 2 ppm per year—it would take about 195 years to achieve this doubling. The combination of a slightly warmer earth and more CO2 will greatly increase the production of food, wood, fiber, and other products by green plants, so the increase will be good for the planet, and will easily outweigh any negative effects. Supposed calamities like the accelerated rise of sea level, ocean acidification, more extreme climate, tropical diseases near the poles, and so on are greatly exaggerated.

“Mitigation” and control efforts that have been proposed will enrich a favored few with good political ties—at the expense of the great majority of mankind, including especially the poor and the citizens of developing nations. These efforts will make almost no change in earth’s temperature. Spain’s recent experiment with green energy destroyed several pre-existing jobs for every green job it created, and it nearly brought the country to bankruptcy.

The frightening warnings that alarmists offer about the effects of doubling CO2 are based on computer models that assume that the direct warming effect of CO2 is multiplied by a large “feedback factor” from CO2-induced changes in water vapor and clouds, which supposedly contribute much more to the greenhouse warming of the earth than CO2. But there is observational evidence that the feedback factor is small and may even be negative. The models are not in good agreement with observations—even if they appear to fit the temperature rise over the last 150 years very well.

Indeed, the computer programs that produce climate change models have been “tuned” to get the desired answer. The values of various parameters like clouds and the concentrations of anthropogenic aerosols are adjusted to get the best fit to observations. And—perhaps partly because of that—they have been unsuccessful in predicting future climate, even over periods as short as fifteen years. In fact, the real values of most parameters, and the physics of how they affect the earth’s climate, are in most cases only roughly known, too roughly to supply accurate enough data for computer predictions. In my judgment, and in that of many other scientists familiar with the issues, the main problem with models has been their treatment of clouds, changes of which probably have a much bigger effect on the temperature of the earth than changing levels of CO2.

What, besides the bias toward a particular result, is wrong with the science? Scientific progress proceeds by the interplay of theory and observation. Theory explains observations and makes predictions about what will be observed in the future. Observations anchor our understanding and weed out the theories that don’t work. This has been the scientific method for more than three hundred years. Recently, the advent of the computer has made possible another branch of inquiry: computer simulation models. Properly used, computer models can enhance and speed up scientific progress. But they are not meant to replace theory and observation and to serve as an authority of their own. We know they fail in economics. All of the proposed controls that would have such a significant impact on the world’s economic future are based on computer models that are so complex and chaotic that many runs are needed before we can get an “average” answer. Yet the models have failed the simple scientific test of prediction. We don’t even have a theory for how accurate the models should be.

There are many honest, hardworking climate scientists who are trying to understand the effects of CO2 on climate, but their work has fallen under suspicion because of the hockey-stick scandal and many other exaggerations about the dangers of increasing CO2. What has transformed climate science from a normal intellectual discipline to a matter of so much controversy?

A major problem has been the co-opting of climate science by politics, ambition, greed, and what seems to be a hereditary human need for a righteous cause. What better cause than saving the planet? Especially if one can get ample, secure funding at the same time? Huge amounts of money are available from governments and wealthy foundations for climate institutes and for climate-related research.

Funding for climate studies is second only to funding for biological sciences. Large academic empires, prizes, elections to honorary societies, fellowships, and other perquisites go to those researchers whose results may help “save the planet.” Every day we read about some real or contrived environmental or ecological effect “proven” to arise from global warming. The total of such claimed effects now runs in the hundreds, all the alleged result of an unexceptional century-long warming of less than 1 degree Celsius. Government subsidies, loan guarantees, and captive customers go to green companies. Carbon-tax revenues flow to governments. As the great Russian poet Pushkin said in his novella Dubrovsky, “If there happens to be a trough, there will be pigs.” Any doubt about apocalyptic climate scenarios could remove many troughs.

What about those who doubt the scientific basis of these claims, or who simply don’t like what is being done to the scientific method they were taught to apply and uphold? Publications of contrary research results in mainstream journals are rare. The occasional heretical article is the result of an inevitable, protracted battle with those who support the dogma and who have their hands on the scales of peer review. As mentioned above, we know from the Climategate emails that the team conspired to prevent contrary publications from seeing the light of day and even discussed getting rid of an editor who seemed to be inclined to admit such contentious material.

Skeptics’ motives are publicly impugned; denigrating names are used routinely in media reports and the blogosphere; and we now see attempts to use the same tactics that Big Brother applied to the skeptical hero, Winston Smith, in Orwell’s 1984. In 2009 a conference of “ecopsychologists” was held at the University of West England to discuss the obvious psychological problems resident in those who do not adhere to the global warming dogma. The premise of these psychologists was that scientists and members of the general population who express objective doubt about the propagated view of global warming are suffering from a kind of mental illness. We know from the Soviet experience that a society can find it easy to consider dissidents to be mentally deranged and act accordingly.

The management of most scientific societies has enthusiastically signed on to the global warming bandwagon. This is not surprising, since governments, as well as many states and foundations, generously fund those who reinforce their desired outcomes under the cover of saving the planet. Certain private industries are also involved: those positioned to profit from enacted controls as well as financial institutions heavily invested in “green technologies” whose rationale disappears the moment global warming is widely understood to be a non-problem. There are known connections and movements of people involved in government policy, scientific societies, and private industry, all with the common thread of influencing the outcome of a set of programs and investments underpinned by the supposed threat of global warming.

My own trade union, the American Physical Society (APS), is a good example, but hardly the worst. An APS Council statement issued on November 18, 2007 states: “The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security, and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now.” This is pretty strong language for physicists, for whom skepticism about evidence was once considered a virtue, and nothing was incontrovertible.

In the fall of 2009 a petition, organized by Fellow of the American Physical Society, Roger Cohen, and containing the signatures of hundreds of distinguished APS members was presented to the APS management with a request that at least the truly embarrassing word “incontrovertible” be taken out of the statement. The APS management’s response was to threaten the petitioners, while grudgingly appointing a committee to consider the request. It was exactly what James Madison warned against. The committee included members whose careers depended on global warming alarmism, and the predictable result was that not one word was changed. Bad as the actions of the APS were, they were far better than those of most other scientific societies, which refused to even reconsider extreme statements on climate.

The situation is even more lamentable for the general public, which is fed a constant stream of propaganda by specialists in environmental issues from the mainstream media and well-funded alarmist blogs. Not unlike functionaries of Orwell’s Ministry of Truth in 1984, with its motto “Ignorance is Strength,” many members of the environmental news media dutifully and uncritically promote the party line of the climate crusade.

However, the situation is slowly getting better. Skeptics are more numerous and better organized than before. In a few cases, leading former adherents have publicly and courageously spoken out against the dogma and its core of establishment promoters. The IPCC itself has come under severe criticism by the international scientific establishment for its series of bizarre errors and organizational failings. Under pressure from a dissident group of Fellows, the Royal Society moved to meaningfully moderate its former radically alarmist position on global warming. And perhaps most important of all, public skepticism has increased significantly, and with it has come a major drop in support of the climate crusade’s attempt to seize control of the “pollutant,” CO2.

I began with a quotation from the preface of the first edition of Mackay’s Extraordinary Popular Delusions and the Madness of Crowds, and it is worth recalling now a quotation from the preface of the second edition: “Men, it has been well said, think in herds; it will be seen that they go mad in herds, while they only recover their senses slowly, one by one.”

In our efforts to conserve the created world, we should not concentrate our efforts on CO2. We should instead focus on issues like damage to local landscapes and waterways by strip mining, inadequate cleanup, hazards to miners, and the release of real pollutants and poisons like mercury, other heavy metals, and organic carcinogens. Much of the potential harm from coal mining can be eliminated, for example, by requirements that land be restored to a condition that is at least as good as, and preferably better than, when the mining began.

Life is about making decisions, and decisions are about trade-offs. We can choose to promote investment in technology that addresses real problems and scientific research that will let us cope with real problems more efficiently. Or we can be caught up in a crusade that seeks to suppress energy use, economic growth, and the benefits that come from the creation of national wealth.

Nuclear Hazards?

Radiation, activists and other hazards


ONE day in 2001, when I was working in the communications department of the Australian Nuclear Science and Technology Organisation, some anti-nuclear activists dropped by for a visit

It was a group of exuberant drama students from Western Australia who had been touring universities, performing a melodramatic play about the horrors of radiation. On this day, they joined one of the free tours of Lucas Heights, including the outdated little research reactor that had been safely fulfilling Australia's nuclear medicine requirements for more than 40 years.

A representative of one of many environmental organisations opposing the construction of a new reactor was accompanying them. When the tour finished, I recall, the ANSTO tour guides were astonished about how little the man who was supposed to be one of Australia's anti-nuclear experts knew about nuclear science.

All of this might now be forgotten except that some days later, the students returned to Lucas Heights. They frolicked for the cameras around the entrance to the site dressed in barrels and handcuffed themselves to the gates, while others climbed the containment building and unfurled a Greenpeace banner.

The media were invited along, and the pictures were splashed across the television news. It was a public relations triumph for Greenpeace.

What failed to make the news is that over the next few days, reports began to filter back to ANSTO about the disruption the protest caused to medical procedures across Australia and overseas. Scores of important diagnostic and other medical procedures were postponed or missed altogether. Some people in the final stages of bone cancer missed out on receiving sophisticated pain relief medication. I started to take phone calls from worried local residents.

In the intervening years, anti-nuclear activism in Australia has not improved. Take Chernobyl for example. Tomorrow is the 25th anniversary of the world's worst nuclear accident, and opinions of the same anti-nuclear experts I encountered 10 years ago can be found in newspapers and on websites.

These opinions always involve outlandish figures of casualties derived from theoretical extrapolations; they argue that if so much radiation was released, then so many people -- always a large number -- must have died. Happily, these arguments are not supported by experience.

The definitive study, described by the International Atomic Energy Agency as the "most comprehensive analysis on human exposures and health consequences of the Chernobyl accident" was produced by the UN Scientific Committee on the Effects of Atomic Radiation.

The UNSCEAR report was assembled by the world's top scientists, epidemiologists and medical professionals after producing and examining hundreds of studies. It was presented to the UN General Assembly in 2000 and has been regularly updated ever since.

The report found that 134 plant staff and emergency workers at Chernobyl suffered acute radiation syndrome. In the first few months after the accident 28 of them died and, by 2006, another 19 died of causes not usually associated with radiation exposure.

The experts were surprised they could not find the diseases they expected to find in populations of people exposed to significant doses of radiation. The prevalence of birth defects and cancers such as leukaemia were no higher than were being experienced before the accident, even among the 600 surviving workers, many of whom received large radiation doses.

The singular exception to this was the incidence of thyroid cancer in local children. A large increase in cases is now thought to be the result of authorities allowing milk from contaminated areas to continue to be sold.

By 2005, about 6000 cases of thyroid cancer in children had been recorded in neighbouring areas, many more than would be otherwise expected. This was a terrible outcome, but since thyroid cancer is treatable, only 15 people had died by 2005.

Further casualties cannot be ruled out but astonishingly, to this day, the deaths that can be attributed to the worst nuclear accident in history are fewer than 100, and are probably closer to 50.

While direct casualties were surprisingly low, the UNSCEAR authors were disturbed to find numerous studies showing that fear of radiation had caused significant increases in the numbers of abortions and suicides, even in regions far removed from Chernobyl. They concluded the mental health impact of Chernobyl was "the largest public health problem unleashed by the accident to date".

Without doubt, Fukushima will also rate as one of the world's worst nuclear accidents, but all indications are that it is not nearly as severe as Chernobyl. The radiation emanating from Fukushima has been considerably lower, while exposures to emergency workers and local populations have been far better managed.

Amazingly, despite the devastation of the site, there have been no radiation-related deaths at Fukushima so far, and only two workers have been hospitalised as a precaution.

The only people to have perished at Fukushima were a man who became trapped in the console of a crane during the earthquake and two who were swept away by the tsunami. The entire toll from the earthquake, remember, is estimated at about 25,000.

While it is not yet over, and radioactivity continues to come out of the devastated plant, the good news is that there are still precisely zero deaths attributable to the release of radiation at the plant, and on the basis of doses received, zero are expected.

No effects on health or significant contamination cases have been identified among the general public evacuated from the area, despite the fact the accident has devastated the plant, and involved fires, explosions, and releases of radioactivity. If there is a single lesson from Chernobyl for the Japanese, it's that in the years to come misinformation is likely to be more dangerous than radiation. To this end, there is nothing harmless about anti-nuclear activists.

WesternsDownfall??

American Thinker article

The Writing On The (Great) Wall

By John Droz, Jr.
It should be no surprise that there are other large countries who don't like the fact that the U.S. is the world's dominant power -- and they would like to take over our position.

Since we are aware of this friction, we tend to think that our biggest threat is from some other country's military. But clearly a direct war would be foolhardy, as there would be no winner from such a conflict.

Our opponents are well aware of this, and have embarked on another scheme. The reality is that we are already under a full assault, but very few are paying attention. Think about it: what would be their best strategy to dethrone us?

A very powerful game plan would consist of a two-part strategy:

1) bankrupting the US; and

2) getting the US to voluntarily slow down its rate of industrialization, giving an opponent the time to overtake us.

Is the (CFL) light bulb going on?

By any financial measure we are in extremely dire circumstances. Unfunded liabilities are in the trillions of dollars. Additionally our society has evolved away from being producers of hard products to providers of soft services. Essentially all levels of public sector employment (government) are at record highs.

Periodically someone gets arrested for promoting a Ponzi scheme, but a critical look would conclude that a lot of how our government works seems disturbingly similar to such charades. For instance, how long can we continue to just print colored water-marked paper to cover our debts? How long can one branch of the government keep writing IOUs to another branch?

A direct consequence of our past success is that we are evolving into a more pampered entitlement society, focused on short term thinking. Delayed gratification is as common a concept as is darning socks. We want it, and want it now!

A corollary to this is that few people really work for rewards anymore. Just showing up and going through the motions for a piddling 20 years now entitles many government employees to lifelong pensions at 80% pay (with medical benefits, of course).

Where did all these materialistic ideas and values come from? Read our history. The US was founded by people with strong religious beliefs. Our competitors are promoting communism and socialism. Which direction are we going now?

"Wait!" some might object. "I don't see any advertisements (on TV, billboards, etc.) for communism and socialism, so how is this being promoted?"

If you really want the answer, look no further than our education system. There are experts who believe that our system is deliberately dumbing us down. The details of that are too long for this overview article, but the answer is there. Amazingly, the undermining of our education system has only taken some 40± years, partly due to a UNESCO-inspired curriculum and reform measures that are replacing excellence with functionality.

"All right," you might say, "it's undeniable that we're in a financial mess, but how can our opponents actually get us, the world leader in developing innovative solutions to numerous issues, to go backwards?"

Hard as it may be to believe, our education system is doing exactly that. Let's look at a prime example: energy -- because plentiful, reliable, affordable energy is the cornerstone for the U.S.'s success as an industrialized society. Put another way, a fundamental difference between developed and third world countries is the latter's lack of reliable and affordable energy (especially electricity).

Today our education system is aggressively promoting all things "renewable." Most citizens will probably say: "So, what's the matter with that?"

Exactly. The fact that this appears to be a reasonable path to take, is indisputable evidence as to how far this regressive propaganda has become embedded into our thinking. The invasion has already taken place and our defenses have been breached!

The reality is that this focus on "renewable" energy is completely devoid of a scientific basis. We have been so successfully indoctrinated that many of us now believe that a wide scale adapting of a fifteenth century technology (wind energy) is a necessary and progressive way forward!

Even the promoters acknowledge wind's limitations (cost, reliability, transmission, etc., etc.), but their answer is always the same: spend more money, as the solution is just over the horizon. (In this light, please reconsider point #1.)

Getting the Big Picture here is critically important, so I'm not going to get into the details, as too many readers' eyes will probably just glaze over.

In simplified terms, every billion dollars the U.S. spends on wind energy development: increases our national debt; is money borrowed from China (our main competitor); and is squandering time, dollars, and effort, the effect of which is putting the brakes on our national progress forward.

So, back to the beginning. The forces that want world domination, have now:

1) led the U.S. to put itself on the brink of bankruptcy; and

2) gotten the US to voluntarily slow down on its industrialization.

So, are we going to fight this insidious and persistent assault on our country, or will we dispute the obvious, throw in the towel, and accept internment (with a promised posh pension, of course)?
