Here's a column in The Times, imagining what the world might look like if the UN's low-fertilty scenario comes true.
The peak is in sight. Even as the population passes seven billion, the growth rate of the world population has halved since the 1960s. The United Nations Population Division issues high, medium and low forecasts. Inevitably the high one (fifteen billion people by 2100) gets more attention than the low one (six billion and falling). But given that the forecasts have generally proved too high for the past few decades, let us imagine for a moment what might happen if that proves true again.
Africa is currently the continent with the highest birth rates, but it also has the fastest economic growth. The past decade has seen Asian-tiger-style growth all across Africa. HIV is in retreat, malaria in decline. When child mortality fell and economic growth boomed like this in Europe, Latin America and Asia, the result was a rapid fall in the birth rate. For fertility to fall, contraception provides the means, but economic growth and public health provide the motive. So the current slow decline in Africa's birth rate may turn into a plummet.
As a science communicator, I found this fascinating.
The following is an email that was sent in 2003 by a very senior scientist, Stephen Schneider, to a long list of other senior scientists about an article in a newspaper by an economist. Read it and see what you think of the economist, Ross McKitrick at the end. Hello all. Ah ha-the latest idiot-McKitrick-reenters the scene. He and another incompetent had a book signing party at the US Capitol-Mike MacCracken went and he can tell you about it-last summer. McKitrick also had an article-oped, highly refereed of course-in the Canadian National Post on June 4 this year. Here is the URL that worked back then: http://www.nationalpost.com/search/site/story.asp?id=045D5241-FD00-4773-B816-76222A771778
It was a scream. He argued there is no such thing as global temperature change, just local-all natural variablity mostly. To prove this he had a graph of temperature trends in Erie Pennsylvania for the past 50 years (this is from memory) which showed a cooling. THat alone proves nothing, but when reading the caption I noticed the trend was for temperature in October and November!! So one station for two months consitituted his "refutation" of global warming-another even dumber than Lomborg economist way out of depth and polemicizing. I showed it to a class of Stanford freshman, and one of them said: "I wonder how many records for various combinations of months they had to run through to find one with a cooling trend?" THe freshman was smarter than this bozo. It is improtant to get that op-ed to simply tell all reporters how unbelievably incompetent he is, and should not even be given the time of day over climate issues, for which his one "contribution" is laughably incompetent. By the way, the Henderson/Castles stuff he mentions is also mostly absurd, but that is a longer discussion you all don't need to get into-check it out in the UCS response to earlier Inhofe polemics with answers I gave them on Henderson/Castles if you want to know more about their bad economics on top of their bad climate science
My latest Mind and Matter column for the Wall Street Journal is about the possibility that big meteorites can trigger volcanic activity:
About 65 million years ago, the dinosaurs and maybe two-thirds of all other species suddenly died out. For three decades, the dominant explanation for this mass extinction has been that it was probably caused by the impact of a large meteorite.
A layer of iridium-rich rock from roughly the right date is the fingerprint that convicted this extraterrestrial killer (iridium is more common in space than in the Earth's crust). Even the bullet hole has apparently been found in the shape of a 110-mile-diameter crater called Chicxulub off the coast of Mexico. The explosion would have been the equivalent of two million hydrogen bombs.
My latest Mind and Matter column from the Wall Street Journal: Earthquakes are natural disasters. However much culpability there is afterward about the building standards that may have worsened the death toll or the response of the emergency authorities, nobody is to blame for the actual shock.
At least, not normally. An exception is the phenomenon of "induced seismicity," whereby human activity such as geothermal energy projects, mining, gas drilling or the filling of reservoirs apparently sets off swarms of very small earthquakes where there are susceptible geological faults and in certain kinds of underlying rock.
A recent report from the U.S. Geological Survey concludes, for example, that a nearby shale gas well probably caused a swarm of 43 very small earthquakes (largest magnitude, 2.8) in Garvin County, Okla., last January. A few hours before the quakes began, the well had ceased hydraulic fracturing or "fracking": that is, injecting high-pressure water into the ground to crack deep rocks.
Here's an interview I did for the Globe and Mail in Toronto during my recent visit to Canada.
Joanne Nova has a really fine essay on Naomi Klein. This is great writing, easily as fluent as Klein herself, only rational. An excerpt:
By building her whole argument on un-scientific quicksand, Klein makes mindless statements that unwittingly apply more to her own arguments than anyone elses. She explores "how the right has systematically used crises-real and trumped up-to push through a brutal ideological agenda designed not to solve the problems that created the crises but rather to enrich elites."
No one uses trumped-up-crises better than the left: Which team is demanding billions to "stop the storms"? And which elites will be enriched? The carbon traders and financiers.
My latest Wall Street Journal Mind and Matter column:
The list of scientific heretics who were persecuted for their radical ideas but eventually proved right keeps getting longer. Last month, Daniel Shechtman won the Nobel Prize for the discovery of quasicrystals, having spent much of his career being told he was wrong.
"I was thrown out of my research group. They said I brought shame on them with what I was saying," he recalled, adding that the doyen of chemistry, the late Linus Pauling, had denounced the theory with the words: "There is no such thing as quasicrystals, only quasi-scientists."
Latest Mind and Matter column in the Wall Street Journal:
"You can't change human nature." The old cliché draws support from the persistence of human behavior in new circumstances. Shakespeare's plays reveal that no matter how much language, technology and mores have changed in the past 400 years, human nature is largely undisturbed. Macbeth's ambition, Hamlet's indecision, Iago's jealousy, Kate's feistiness and Juliet's love are all instantly understandable.
Recently, however, geneticists have surprised themselves by finding evidence of recent and rapid changes in human genomes in response to the pressures of civilization. For example, fair skin allows more absorption of the sun's ultraviolet rays necessary for the skin to make vitamin D. So when the northern Europeans, living in a climate with little sunshine, started to farm wheat, a food low in vitamin D, they evolved fair skin to compensate and get more of the vitamin.
There's a fine article at Spiked by Tim Black exposing what Robert* Malthus actually said. Malthus was a reactionary nostalgic pessimist who was not just wrong about population growth outstripping food supply. He was also wrong in his cynicism about helping the poor lest they breed more.
(*Everybody calls him Thomas these days, whereas his contemporaries all called him Robert, which was his second name. Calling him Thomas is like calling the first director of the FBI John Hoover.)
Mylecture on scientific heresyto the RSA this week has been reprinted onbishop-hill.netandwattsupwiththat.com, where it has generated much discussion. Thanks to Andrew Montford and Antony Watts for their interest.
My latest Mind and Matter column in the Wall Street Journal:
This Halloween, the United Nations declared over the summer, a baby will be born somewhere on Earth who will tip the world's population over seven billion for the first time. Truly do international bureaucrats have the power of prophecy!
The precision is bunk, of course, or rather a public-relations gimmick. According to demographers, nobody knows the exact population of the world to within 100 million. (Incidentally, the record-setting baby will not be the seven billionth human being to have existed, as some press reports have implied-more like the 108 billionth.)
Sad news of the death of John McCarthy, former professor of Computer Science at Stanford University, who coined the very term "artificial intelligence" in 1955 and invented the LISP programming language in 1958.
McCarthy was a true "progressive" in that he appreciated the rapid and dramatic improvements in human living standards brought about by innovation. It was from McCarthy's website that I first learned of Thomas Babington Macaulay's remarks, in the Edinburgh Review, that I often quote -- "We cannot absolutely prove that those are in error who tell us that society has reached a turning point, that we have seen our best days. But so said all before us, and with just as much apparent reason ... On what principle is it that, when we see nothing but improvement behind us, we are to expect nothing but deterioration before us".
This alerted me to the startling fact that even 200 years ago, when human living standards had barely begun to improve, intellectuals were already lamenting the imminent and inevitable end of that improvement. They were wrong then and they are wrong now.
Bronwen Maddox, editor of Prospect, has a long article entitled "Just Too Many?", arguing that the world needs to end its taboo on discussing population and population control. This is of course pegged on the United Nations' somewhat gimmicky announcement that the world will pass seven billion people on 31st October. Thugh it is generally a good essay, like so much of the coverage, Maddox's article fails sufficiently to distinguish the top-down approach to population, which did indeed become taboo after 1994, and the bottom-up one, which did not. The bottom up one focuses on economic development and public health, which together drive down birth rates by enabling women to plan smaller families rather than keep breeding heirs and spares. The top-down approach targets birth rates themselves. I would argue that its cruelties should make us cautious before returning to it. I have sent the following letter to the editor at Prospect:
Your population cover story makes a good case that public-sector experts effectively turned their backs on the issue following the intervention of an unusual mixture of conservatives and feminists at the Cairo conference in 1994. Was this silence entirely a bad thing? Do not underestimate the harm done by the coercion recommended in the 1970s by western intellectuals -- and implemented. Egged on by Western governments and pressure groups, coerced sterilisation became a pattern all across Asia in the 1970s. Chinese women were forcibly taken from their homes to be sterilised. Cheered on by Robert McNamara's World Bank, Sanjay Gandhi ran a vast campaign of rewards and coercion to force 8 million poor Indians to accept vasectomies. Yet we now know that bottom-up forces, chiefly public health improvements and economic growth, generally reduce birth rates even faster than top-down coercion (which bodes well for Africa with its recent rapid economic growth). The availability of contraception is necessary but not sufficient. Maybe the inattention of the international quangocracy is not always a bad thing.
After writing this I came across an unusually (for the BBC) well-researched and well-informed essay on this subject by Mike Gallagher on the BBC, which makes the same point in greater detail. Some extracts:
he Australian has published my review of Donna Laframboise's book here.
The review prompted a tweet from Michael Mann that I was wrong to say the IPCC had dropped the hockey stick. Here's a source: judge for yourself.
Here's the text of the review:
Chris Huhne, the UK energy secretary, boasts that wind farms and other renewable energy schemes will create 9,000 jobs this year. Since they are all subsidised, each one is in effect sponsored by a newly unemployed person elsewhere in the economy. Shale gas already supports 140,000 jobs in Pennsylvania alone, up from about zero in 2007. This is without subsidy; in fact, the reverse -- hefty tax revenue. Pennsylvania's population is one-fifth of Britain's.
From The Economist comes news that does not surprise me and reinforces my view, aired in mydebate with Bill Gates, that pessimism about Africa is overdone and trade is transforming Africa for the better:
AFRICA has made a phenomenal leap in the last decade. Its economy is growing faster than that of any other continent. Foreign investment is at an all-time high; Senegal has lower borrowing costs than Ireland. The idea of a black African billionaire-once outlandish except for kleptocratic dictators-is commonplace now. At the same time an expanding African middle class (similar in size to those in India and China) is sucking in consumer goods. Poverty, famine and disease are still a problem but less so than in the late 20th century, not least thanks to advances in combating HIV and malaria.
Africa's mood is more optimistic than at any time since the independence era of the 1960s. This appears to be a real turning point for the continent. About a third of its growth is due to the (probably temporary) rise in commodity prices. Some countries have been clever enough to use profits to build new infrastructure. The arrival of China on the scene-as investor and a low-cost builder-has accelerated this trend. Other Asian economies are following its lead, from Korea to Turkey.
Nicely put by Michael Barone:
...A similar but more peaceable fate is befalling believers in what I think can be called the religion of the global warming alarmists.
They have an unshakeable faith that manmade carbon emissions will produce a hotter climate, causing multiple natural disasters. Their insistence that we can be absolutely certain this will come to pass is based not on science -- which is never fully settled, witness the recent experiments that may undermine Albert Einstein's theory of relativity -- but on something very much like religious faith.
Here is a letter I sent to the editor and deputy editor of The Economist.
A comment on the piece by James Astill about the Berkeley temperature study. Most of the article is a sensible discussion of a deadly dull piece of statistics that changes nothing. But it's topped and tailed with claims that this leaves little room for doubters, and that the warming is "fast". Both these conclusions are badly wrong.
Latest Mind and Matter column in the Wall Street Journal is the extraordinary story of modern chicken genetics.
Of all the amphibians, reptiles, birds and mammals in the world, the most abundant species is probably the chicken. At any one time, approximately 20 billion cocks and hens are alive on the planet (though never for long).
Donna Laframboise is a journalist and civil libertarian in Toronto, who made her name as a fearless investigative reporter in the 1990s. She has recently been investigating the Intergovernmental Panel on Climate Change and has come up with startling results about how its reports are compiled. For those of us who took the IPCC's evaluations of climate at face value when they came out -- I know I did -- and thought that they were based on an impartial and careful process that relied on peer reviewed evidence, these revelations are shocking. Her book The Delinquent Teenager is now available on kindle and will shortly be in paperback. It is one of the most important pieces of investigative journalism in recent years. It demolishes the argument that we need the mainstream media because the blogosphere will never do the hard work of investigative journalism. The opposite is true.
Here I take the liberty of extracting one fairly lengthy tale from the book, but there are many more:
The IPCC's transparency shortcomings have been obvious for some time. In 2005 Steve McIntyre, a Canadian with a PhD Masters degree in mathematics and a flair for statistics, was invited by the IPCC to be an expert reviewer for what would become the 2007 edition of the Climate Bible. McIntyre, who writes theClimateAudit.org blog, was by then a well-known IPCC critic, so this invitation was a promising sign. But it didn't take long for matters to go off the rails.
Here's my latest Mind and Matter column from the Wall Street Journal:
Writing about science carries the risk of embarrassment. If you champion a theory and it gets disproved, you have some explaining to do. So it is nice when a theory you choose does win the race.
Here's an article I wrote for this week's Spectator about UK energy policy. Wind must give way to gas before it ruins us all, and our landscapes.
Which would you rather have in the view from your house? A thing about the size of a domestic garage, or eight towers twice the height of Nelson's column with blades noisily thrumming the air. The energy they can produce over ten years is similar: eight wind turbines of 2.5-megawatts (working at roughly 25% capacity) roughly equal the output of an average Pennsylvania shale gas well (converted to electricity at 50% efficiency) in its first ten years.
Difficult choice? Let's make it easier. The gas well can be hidden in a hollow, behind a hedge. The eight wind turbines must be on top of hills, because that is where the wind blows, visible for up to 40 miles. And they require the construction of new pylons marching to the towns; the gas well is connected by an underground pipe.
Fenbeagle has done a cartoon featuring a rational optimist...
From My latest Mind and Matter Column at he Wall Street Journal:
The science of evolutionary psychology has flourished in recent years by asking "why" as well as "how" questions about animal and human behavior, and answering them with historical explanations.
I have a book review in the Wall Street Journal of Robert Laughlin's book Powering the Future.
These are the first two paragraphs:
Many environmentalists believe that carbon dioxide from the burning of fossil fuels will cause a climate crisis toward the end of this century. Environmentalists also raise the alarm that we have reached "peak oil" and that fossil fuels will run out by the middle of the century. That both views cannot be true rarely seems to bother those who hold them. Either consequence, we're told, makes the world's conversion to a low-carbon energy system an urgent matter.
My latest Mind and Matter column for the Wall Street Journal is on metaphors and analogies:
Monkeys can reason by using analogy, it seems. In an experiment recently reported in the journal Psychological Science, baboons in a lab proved capable of realizing that a pair of oval shapes is "like" a pair of square shapes and "unlike" a pair made of two different shapes. This finding suggests that you can have analogy without language.
Fascinating interview with the founder of Continental Resources Harold Hamm in the Wall Street Journal.
Harold Hamm calculates that if Washington would allow more drilling permits for oil and natural gas on federal lands and federal waters, the government could over time raise $18 trillion in royalties. That's more than the U.S. national debt.
The Bakken oil fields of North Dakota are proving to be huge. possibly 24 billion barrels.
I have an op-ed article in the Times today, arguing that there is light at the end of the tunnel for the world's and the British economy: the long-term gains from living within our means are huge:
Matthew Parris hit a nerve last Saturday with his argument that we have lived beyond our means and must now expect to have to work harder and be 25 per cent poorer. It resonated with me as well as many readers. He cut through all the detail of debt, default and deficits to extract an essential truth. The West has run a pyramid scheme, spending borrowed capital to boost current living standards. From pensions to mortgages, from public spending to consumer extravagance, the reckoning has arrived.
Here is my latest Mind and Matter column in the Wall Street Journal
There are many mysteries about Ray, the 17-year-old English-speaking "forest boy" who walked into the city hall in Berlin on Sept. 5, claiming to have lived wild in the woods for five years with his father-until his father recently died in a fall. Judging by his rucksack and his speech, he was not a fully feral child, reared by wild animals and unacquainted with language.
I have the following opinion piece in today's Wall Street Journal, adapted from my forthcoming Hayek lecture.
The crowd-sourced, wikinomic cloud is the new, new thing that all management consultants are now telling their clients to embrace. Yet the cloud is not a new thing at all. It has been the source of human invention all along. Human technological advancement depends not on individual intelligence but on collective idea sharing, and it has done so for tens of thousands of years. Human progress waxes and wanes according to how much people connect and exchange.
