Fox News has dug up some remarkable botched predictions about the environment. Most are familar but three were new to me:
Happy New Year.
I mean it. 2011 will see horrible things, no doubt, but it will also see a continuing incremental reduction in poverty, hunger, illness and suffering, plus a continuing incremental rise in most measures of human and planetary wellbeing.
Here's a fine blast of optimism from John Tierney in the New York Times. He took a bet with a peak-oiler and won hands down.

Don't look for the soul in the language of DNA
Back in the genomic bronze age-the 1990s-scientists used to think that there would prove to be lots of unique human genes found in no other animal. They assumed that different species would have many different genes. One of the big shocks of sequencing genomes was not just the humiliating news that human beings have the same number of genes as a mouse, but that we have the same genes, give or take a handful.
Rachel Carson, in her hugely influential book Silent Spring, wrote that she expected an epidemic of cancer caused by chemicals in the environment, especially DDT, indeed she thought it had already begun in the early 1960s:
``No longer are exposures to dangerous chemicals occupational alone; they have entered the environment of everyone-even of children as yet unborn. It is hardly surprising, therefore, that we are now aware of an alarming increase in malignant disease.
The increase itself is no mere matter of subjective impressions. The monthly report of the Office of Vital Statistics for July 1959 states that malignant growths, including those of the lymphatic and blood-forming tissues, accounted for 15 per cent of the deaths in 1958 compared with only 4 per cent in 1900. Judging by the present incidence of the disease, the American Cancer Society estimates that 45,000,000 Americans now living will eventually develop cancer. This means that malignant disease will strike two out of three families. The situation with respect to children is even more deeply disturbing. A quarter century ago, cancer in children was considered a medical rarity. Today, more American school children die of cancer than from any other disease. So serious has this situation become that Boston has established the first hospital in the United States devoted exclusively to the treatment of children with cancer. Twelve per cent of all deaths in children between the ages of one and fourteen are caused by cancer. Large numbers of malignant tumors are discovered clinically in children under the age of five, but it is an even grimmer fact that significant numbers of such growths are present at or before birth. Dr. W. C. Hueper of the National Cancer Institute, a foremost authority on environmental cancer, has suggested that congenital cancers and cancers in infants may be related to the action of cancer-producing agents to which the mother has been exposed during pregnancy and which penetrate the placenta to act on the rapidly developing fetal tissues.''
My latest Mind and Matter column in the Wall Street Journal is about how the human brain deals with the future. Here it is with added links.
I recently came across the phrase "remembering the future." Rather than some empty poetic paradox, it appeared in an article about a neuroscientific experiment that tested a hypothesis of Karl Friston of University College, London, that the brain is more active when it is surprised.
In the study, volunteers watched patterns of moving dots while having their brains scanned. Occasionally, a dot would appear out of step. Although there was the same number of dots, the visual part of the subjects' brains was more active when the dots broke step. According to Arjen Alink of the Max Planck Institute in Frankfurt, Germany, who did the experiment, the brains were predicting what would happen next and having to work harder when their predictions failed. They were "remembering the future."
Bishop Hill has a review of Tim Worstall's book Chasing Rainbows, which reminds me that I meant to write about this book. I wrote a cover quote for it that described it `fearless, fresh, forensic and funny'.
What is particularly clever about the book is the way that Worstall makes economic theory so digestible, even delicious. He refutes the dreary cliche so popular among environmentalists that economics just `does not get' the environment (by which they usually mean that they would like to do the equivalent of repeal the laws of gravity and make things to happen even if they make no sense for people: like getting people to give up cheap forms of energy to take up expensive ones). Quite the reverse is true: environmentalists all too often just don't get what economists are trying to tell them.
I especially liked this little section which so neatly eviscerates the Stern Report:
(picture from Eden's Path)
Here's a letter I sent to the editor of The Economist:
Sir,
Last winter, we were told by scientists that it was `stupid' to take the cold weather as evidence against global warming. Yet this winter you are quite happy to speculate, entirely against the consensus view, that the cold weather is evidence for global warming (`A Cold Warming', Dec 4th). In support of this fancy, you cite `some' evidence that summer heat `may' induce shifts in atmospheric circulation that `might' encourage seasonal patterns that would `probably' mean more cold winters in Britain. Spare us the astrology, please.
There is a big new report on shale gas from the No Hot Air website. It is far too expensive for me, but here is a summary of what it supposedly concludes:
The key issue going forward for natural gas is not managing supply, but creating demand.
The US success in shale gas technology can be replicated in multiple locations world-wide.
My latest Wall Street Journal column is on the work of Sugata Mitra, who is turning education upside down with the help of the internet:
For some time now I have been aware of environmentalists who dislike the way their agendas have been hijacked by climate change. The orthodox view is that climate change is raising the profile of all environmental issues, but is it?
Can it really be easier to raise money for a wildlife conservation project in Madagascar or Galapagos when everybody is saying that the major threat is not habitat loss or invasive species, but slow warming?
Can it really be helpful for bird conservation when green groups take money from wind companies which kill golden eagles?
Update: I have misled the reader about the quantity of neodymium in a wind turbine magnet. The magnet is not pure neodymium, but an alloy of Nd, iron and Boron. So there's a lot less than 2.5 tonnes of Nd itself in a 2.5MW turbine magnet. There's still plenty of it, though. Hat tip Tim Worstall.
2nd Update: I am told 270kg of Nd per megawatt is about right, though it will vary with different kinds of magnet. That means about 675kg of Nd in a 2.5MW turbine. Hat tip Alan Bates.
"The broad generalisations that label Africa a continent of failure and business losses are plain wrong. They are part of that same pessimism that insists the only products worth investing in are misery and minerals."
We are getting somewhere. There is a long response to my Times article from ocean acidification scientists here. This makes me rather happy. The response confirms the accuracy of my main points. I have sent the following response to Nature's website, which carried a report on this matter:
I am glad to have my main point confirmed by the reply: that there is in fact no evidence for net biological harm likely as a result of realistic changes in ocean pH. This is a huge and welcome change from the exaggerated rhetoric that has been used on this topic.
The reply also confirms the accuracy of virtually all of my factual assertions about the likely change in pH, the natural variation in pH and other issues, including the involvement of a Greenpeace ship in a research project. Only my interpretation is challenged.
On his blog, A Very Remote Period Indeed, Julien Riel-Salvatore discusses his recent paper about Neanderthals and innovation:
I'm quoted [in the press release] as saying, among other things, that this study helps 'rehabilitate' Neanderthals by showing that they were able to develop some of the accoutrements of behavioral modernity independent of any contact with modern humans. While I've caught a bit of flak from some friends and colleagues for that turn of phrase, I stand by my statement -this study helps to cast Neanderthals in a much more positive light than they have been for a long while now.
In my book, I argue that Neanderthals --though highly intelligent -- did not show a tendency to innovate, because they did not show a tendency to exchange (their artefacts never come from far away), and this kept their toolkit much the same till the end. The discovery of Neanderthals innovating would therefore be a blow to my argument.
I have just found at Spiked Online Brendan O'Neill's superb recent essay on whether the earth is finite, and I heartily recommend it. Here's a sample:
Over the past 200 years, Malthusians have tended to look at people as simply the users-up of scarce resources. They have tended to view nature as the producer of things and mankind as the consumer of things. And their view of people as little more than consumers - almost as parasites - inevitably leads to them seeing human beings as the cause of every modern ill, and therefore reducing the number of human beings as the solution to every modern ill. Their focus on finiteness means they conceive of humanity as a kind of bovine force, hoovering up everything that it comes across.
I read this while sitting in a hotel room at San Francisco airport. Huge jets queue for take off in full view of my window. I am in the middle of a great conurbation. But between me and the jets lies a stretch of water, an arm of the Bay itself. And the water is a bird watcher's paradise. There are rafts of ducks such as buffleheads and wigeon. There are pelicans, grebes and two speces of gull. Along the shore there are great white and little egrets, willets, whimbrels, grey plovers, stints, dowitchers, avocets, yellow-legs and tight flocks of sandpipers. Sea lions cruise a litle further out, and an osprey has just plunged into the water after a fish.
Here is my latest Wall Street Journal column. It led me into the etymology of the word `optimism' and the realisation that at first it meant almost the opposite of what we now mean by it, namely that the world was at its `optimum' and could not improve.
A Haitian who survived the January earthquake and has so far escaped cholera recently told a reporter that this month's Hurricane Tomas wasn't as bad as he thought it would be, "thank God." I know it's often just a verbal tic, but it has always struck me as odd that people who survive natural disasters thank God for saving them but rarely blame Him for the disaster.
It has been quite a decade for natural disasters: the Indian Ocean tsunami, Hurricane Katrina, Burma's cyclone, Pakistan's floods, China's quake. Only once to my knowledge has there been much media debate about whether these disasters were "acts of God"-after the Indian Ocean tsunami of 2004, perhaps because it happened on the day after Christmas. In any case, I always felt the phrase applied better to 9/11, considering the motivation of the terrorists.
A new paper in Science casts further doubt on the usefulness of the Paleocene-Eocene Thermal Maximum (PETM) as a warning of what we face from man-made carbon emissions. Tropical rain forests became more diverse, not less, during the warm spell.
The paleontologist who made this discovery told Science News:
"We were expecting to find rapid extinction, a total change in the forest," says study leader Carlos Jaramillo, a biologist at the Smithsonian Tropical Research Institute in Balboa, Panama. "What we found was just the opposite - a very fast addition of many new species, and a huge spike in the diversity of tropical plants."
Here is the letter that David MacKay sent me following my article in The Times and to which I replied.
(I have gone to weblinks for his charts and in one case come up with a slightly different version -- the sea ice graph I could not find the exact one he included so I have found another from the same source which has more years on it than his version, but it's the same data and the same source.) Update: all graphs now correct!
Don Boudreaux has a lovely essay in the Christian Science Monitor (interest declaration: he mentions my book) in which he makes the point people often miss about markets, that they encourage diversity rather than one-size-fits-all solutions:
Contrast the multitude of different market-generated and voluntarily adopted ideas with the ideas of progressives - for example, progressives' idea thatgovernment must regulate the fatcontent of foods.
Each of us can decide how much we value, say,juicy burgersand double-dark chocolate ice cream compared to how much we value a trim waistline and longer life expectancy. And each of us values these benefits differently. The dietary choices that I make for myself are right for me, but I cannot know if they are right for anyone else. Progressives, in contrast, falsely assume there's a single correct metric, for the whole country, that determines for everyone how to trade off the satisfaction of eatingtasty but fatty foodsfor the benefit of being healthier.
There is a hilarious letter in today's Times from three FRS professors about my recent artilce on ocean acidification.
Despite conceding the factual truth of my article in detail, they tell me to brush up on chemistry then give no examples of me getting anything wrong.
They concede my point that any shift of acidity will be within natural ranges. Thanks. But say it could be much larger `in the future'. No numbers, note. They mean in several centuries.
UPDATE: David MacKay's letter is now up in a separate post here
Some weeks ago I wrote an article for The Times about why I no longer find persuasive the IPCC's arguments that today's climate change is unprecedented, fast and dangerous.
