The Overpopulatiom Myth -- as published in Prospect magazine

15 March 2010

Many of today’s most-respected thinkers, from Stephen Hawking to David Attenborough, argue that our efforts to fight climate change and other environmental perils will all fail unless we “do something” about population growth. In the Universe in a Nutshell, Hawking declares that, “in the last 200 years, population growth has become exponential… The world population doubles every forty years.”

But this is nonsense. For a start, there is no exponential growth. In fact, population growth is slowing. For more than three decades now, the average number of babies being born to women in most of the world has been in decline. Globally, women today have half as many babies as their mothers did, mostly out of choice. They are doing it for their own good, the good of their families, and, if it helps the planet too, then so much the better.

Here are the numbers. Forty years ago, the average woman had between five and six kids. Now she has 2.6. This is getting close to the replacement level which, allowing for girls who don’t make it to adulthood, is around 2.3. As I show in my new book, Peoplequake, half the world already has a fertility rate below the long-term replacement level. That includes all of Europe, much of the Caribbean and the far east from Japan to Vietnam and Thailand, Australia, Canada, Sri Lanka, Turkey, Algeria, Kazakhstan, and Tunisia.

It also includes China, where the state decides how many children couples can have. This is brutal and repulsive. But the odd thing is that it may not make much difference any more: Chinese communities around the world have gone the same way without any compulsion—Taiwan, Singapore, and even Hong Kong. When Britain handed Hong Kong back to China in 1997, it had the lowest fertility rate in the world: below one child per woman.

So why is this happening? Demographers used to say that women only started having fewer children when they got educated and the economy got rich, as in Europe. But tell that to the women of Bangladesh, one of the world’s poorest nations, where girls are among the least educated in the world, and mostly marry in their mid-teens. They have just three children now, less than half the number their mothers had. India is even lower, at 2.8. Tell that also to the women of Brazil. In this hotbed of Catholicism, women have two children on average—and this is falling. Nothing the priests say can stop it.

Women are doing this because, for the first time in history, they can. Better healthcare and sanitation mean that most babies now live to grow up. It is no longer necessary to have five or six children to ensure the next generation—so they don’t.

There are holdouts, of course. In parts of rural Africa, women still have five or more children. But even here they are being rational. Women mostly run the farms, and they need the kids to mind the animals and work in the fields.

Then there is the middle east, where traditional patriarchy still rules. In remote villages in Yemen, girls as young as 11 are forced into marriage. They still have six babies on average. But even the middle east is changing. Take Iran. In the past 20 years, Iranian women have gone from having eight children to less than two—1.7 in fact—whatever the mullahs say.

The big story here is that rich or poor, socialist or capitalist, Muslim or Catholic, secular or devout, with or without tough government birth control policies in place, most countries tell the same tale of a reproductive revolution.

That doesn’t mean population growth has ceased. The world’s population is still rising by 70m a year. This is because there is a time lag: the huge numbers of young women born during the earlier baby boom may only have had two children each. That is still a lot of children. But within a generation, the world’s population will almost certainly be stable, and is very likely to be falling by mid-century. In the US they are calling my new book “The Coming Population Crash.”

Is this good news for the environment and for the planet’s resources? Clearly, other things being equal, fewer people will do less damage to the planet. But it won’t on its own do a lot to solve the world’s environmental problems, because the second myth about population growth is that it is the driving force behind our wrecking of the planet.

In fact, rising consumption today far outstrips the rising headcount as a threat to the planet. And most of the extra consumption has been in rich countries that have long since given up adding substantial numbers to their population, while most of the remaining population growth is in countries with a very small impact on the planet. By almost any measure you choose, a small proportion of the world’s people take the majority of the world’s resources and produce the majority of its pollution.

Let’s look at carbon dioxide emissions: the biggest current concern because of climate change. The world’s richest half billion people—that’s about 7 per cent of the global population—are responsible for half of the world’s carbon dioxide emissions. Meanwhile, the poorest 50 per cent of the population are responsible for just 7 per cent of emissions. Virtually all of the extra 2bn or so people expected on this planet in the coming 30 or 40 years will be in this poor half of the world. Stopping that, even if it were possible, would have only a minimal effect on global emissions, or other global threats.

Ah, you say, but what about future generations? All those big families in Africa will have yet bigger families. Well, that’s an issue of course. But let’s be clear about the scale of the difference involved. The carbon emissions of one American today are equivalent to those of around four Chinese, 20 Indians, 30 Pakistanis, 40 Nigerians or 250 Ethiopians. A woman in rural Ethiopia can have ten children and, in the unlikely event that those ten children all live to adulthood and have ten children of their own, the entire clan of more than a hundred will still be emitting less carbon dioxide than you or me. It is over-consumption, not over-population that matters.

Economists predict the world’s economy will grow by 400 per cent by 2050. If this does indeed happen, less than a tenth of that growth will be due to rising human numbers. True, some of those extra poor people might one day become rich. And if they do—and I hope they do—their impact on the planet will be greater. But it is the height of arrogance for us in the rich world to downplay the importance of our own environmental footprint because future generations of poor people might one day have the temerity to get as rich and destructive as us. How dare we?

Some green activists need to take a long hard look at themselves. We all like to think of ourselves as progressives. But Robert Malthus, the man who first warned 200 years ago that population growth would produce demographic armageddon, was in his time a favourite of capitalist mill owners. He opposed Victorian charities because he said they were only making matters worse for the poor, encouraging them to breed. He said the workhouses were too lenient. Progressives of the day hated him. Charles Dickens attacked him in several books: when Oliver Twist asked for more gruel in the workhouse, for instance, that was a satire on a newly introduced get-tough law on workhouses, known popularly as Malthus’s Law. In Hard Times, the headmaster obsessed with facts, Thomas Gradgrind, had a son called Malthus. In A Christmas Carol, Ebenezer Scrooge was also widely seen at the time as a caricature of Malthus.

Malthus, it should be remembered, spent many years teaching British colonial administrators before they went out to run the empire. They adopted his ideas that famine and disease were the result of overbreeding, so the victims should be allowed to die. It was Malthusian thinking that led to the huge and unnecessary death toll in the Irish potato famine.

We must not follow the lure of Malthus, and blame the world’s poor for the environmental damaged caused overwhelmingly by us: the rich. The truth is that the population bomb is being defused round the world. But the consumption bomb is still primed and ever more dangerous.

Climategate -- those emails explained

10 February 2010

I have been up to my ears in Climategate.  Last week the Guardian published extended extracts from my 28,000-word dossier examining the content and the context of the notorious leaked/hacked emails from the University of East Anglia's Climatic Research Unit.  Now the full text is online, and open for comments.  Read it here:  http://www.guardian.co.uk/environment/hacked-climate-science-emails

It begins like this:

"This story is dark; there are no heroes. Environmentalists will be distressed at what happens in the labs; many may think we should not publish for fear of wrecking the already battered cause of fighting climate change. But some of it, according to the British government's Information Commissioner, may have been illegal.

Remember two other things. First, this was war. The scientists were under intense and prolonged attack, they believed, from politically and commercially motivated people who wanted to prevent them from doing their science and trash their work. And they had, as their most vocal protagonist Professor Michael Mann puts it in one email, "dirty laundry one doesn't want to fall into the hands of those who might potentially try to distort things ..."

Meanwhile, their attackers came to believe that the scientists were fraudsters. In many ways, what follows is a Shakespearean tragedy of misunderstood motives.

I wrote the offending article. I stand by it

23 January 2010

From the Indepedent

 

Back in 1999, I wrote an article in New Scientist magazine quoting a leading Indian glaciologist that global warming was likely to melt all the Himalayan glaciers by 2035. Syed Hasnain told me that was his conclusion in an unpublished report to the International Commission on Snow and Ice. Eight years later, the same claim was repeated by the IPCC in a major report.

I write regularly about climate change. But I had stopped repeating the prediction years ago after British glaciologists warned me it was unreliable. So I was surprised when I saw it in the 2007 IPCC report, and defended late last year by the IPCC chairman. I figured it must have been fully authenticated, and mentioned it again myself, in an article before the Copenhagen climate conference.

So my jaw dropped when a Canadian glaciologist emailed me to say that not only was that 2035 date still nonsense, but that he had followed the trail of scientific references from the IPCC report and found it led to my old article. Moreover, Hasnain's report never contained what he had told me (and others) that it would.

I stand by my story. That's what Hasnain told me. He was the authority, I was the humble scribe. But my trust that scientists work to higher standards than journalists is dented. And perhaps our old stories should go back to wrapping fish and chips.

COPENHAGEN: Looking for a Silver Lining

16 January 2010

Much was left undone in Copenhagen, and the many loopholes in the climate accord could lead to rising emissions. But the conference averted disaster by keeping the UN climate negotiations alive, and some expressed hope that the growth of renewable energy technology may ultimately save the day.

CLIMATEGATE: Anatomy of a public relations disaster

16 January 2010

The way that climate scientists have handled the fallout from the leaking of hacked e-mails is a case study in how not to respond to a crisis. But it also points to the need for climate researchers to operate with greater transparency and to provide more open access to data.
