Welcome to Matt Ridley's Blog

My column in last week's Times was on the rise in employment, reforms to welfare and the productivity puzzle in Britain:

Successful innovations are sometimes low-tech: corrugated iron, for example, or the word “OK”. In this vein, as Iain Duncan Smith will say in a speech today in South London, a single piece of paper seems to be making quite a difference to Britain’s unemployment problem. It’s called the “claimant commitment” and it has been rolling out to job centres since October last year; by the end of this month it will be universal.

My review for The Times of James Lovelock's new book, A Rough Ride to the Future.

This book reveals that James Lovelock, at 94, has not lost his sparkling intelligence, his lucid prose style, or his cheerful humanity. May Gaia grant that we all have such talents in our tenth decades, because the inventor of gadgets and eco-visionary has lived long enough to recant some of the less sensible views he espoused in his eighties.

My review of William Easterly's book The Tyranny of Experts for The Times:

Imagine, writes the economist William Easterly, that in 2010 more than 20,000 farmers in rural Ohio had been forced from their land by soldiers, their cows slaughtered, their harvest torched and one of their sons killed — all to make way for a British forestry project, financed and promoted by the World Bank. Imagine that when the story broke, the World Bank promised an investigation that never happened.

My Times column is on the missing airliner and Occam's razor.

The tragic disappearance of all 239 people on board flight MH370 in the Indian Ocean has one really peculiar feature to it: none of the possible explanations is remotely plausible, yet one of them must be true.

My Times column is on technology and jobs:

Bill Gates voiced a thought in a speech last week that is increasingly troubling America’s technical elite — that technology is about to make many, many people redundant. Advances in software, he said, will reduce demand for jobs, substituting robots for drivers, waiters or nurses.

The last time that I was in Silicon Valley I found the tech-heads fretting about this in direct proportion to their optimism about technology. That is to say, the more excited they are that the “singularity” is near — the moment when computers become so clever at making themselves even cleverer that the process accelerates to infinity — the more worried they are that there will be mass unemployment as a result.

My Times column is on malaria, TB and Aids -- all in steady decline, a fact that officials and journalists seem reluctant to report:

There’s a tendency among public officials and journalists, when they discuss disease, to dress good news up as bad. My favourite example was a BBC website headline from 2004 when mortality from the human form of mad-cow disease, which had been falling for two years, rose from 16 to 17 cases: “Figures show rise in vCJD deaths” wailed the headline. (The incidence fell to eight the next year and zero by 2012, unreported.) Talk about grasping at straws of pessimism.

My Times column is on harm reduction, Swedish snus and e-cigarettes:

Is this the end of smoking? Not if the bureaucrats can help it.

Sweden’s reputation for solving policy problems, from education to banking, is all the rage. The Swedes are also ahead of the rest of Europe in tackling smoking. They have by far the fewest smokers per head of population of all EU countries. Lung cancer mortality in Swedish men over 35 is less than half the British rate.

This is my column in the Times this week. I have added some updates in the text and below.

In the old days we would have drowned a witch to stop the floods. These days the Green Party, Greenpeace and Ed Miliband demand we purge the climate sceptics. No insult is too strong for sceptics these days: they are “wilfully ignorant” (Ed Davey), “headless chickens” (the Prince of Wales) or “flat-earthers” (Lord Krebs), with “diplomas in idiocy” (one of my fellow Times columnists).

My recent Times column on new discoveries in the history of our species:

It is somehow appropriate that the 850,000-year-old footprints found on a beach in Norfolk last May, and announced last week, have since been washed away. Why? Because the ephemeral nature of that extraordinary discovery underlines the ever-changing nature of scientific knowledge. Science is not a catalogue of known facts; it is the discovery of new forms of ignorance.

For those who thought they knew the history of the human species, the past few years have been especially humbling. There has been a torrent of surprising discoveries that has washed away an awful lot of what we thought we knew, leaving behind both much more knowledge and many more questions.

My Times column this week was on the facts behind the inequality debate:

The Swedish data impresario Hans Rosling recently asked some British people to estimate the average number of births per woman in Bangladesh and gave them four possible answers. Just 12 per cent got the right answer (2.5), whereas 25 per cent of chimpanzees would have got it right if the answers had been written on four bananas from which they could choose one at random. Remarkably, university-educated Britons did worse, not better, than non-graduates. It is not so much what you don’t know as what you know that isn’t so.

Hold that thought while I introduce you to Tom Perkins, the Silicon Valley venture capitalist and former husband of the crime writer Danielle Steel, who stirred up fury in America when he wrote to The Wall Street Journal last month complaining about a rising tide of hatred against the very rich, and indirectly but crassly comparing it to Kristallnacht. A few days later President Obama used his State of the Union speech to take aim at inequality. In this country, too, inequality is one thing that much rankles with most people, as the 50 per cent tax rate row reveals.

This is Stephen McIntyre’s response to me, commenting on the letters from Professor Keith Briffa to the Times in response to my column on the widespread problem of withheld adverse data. It makes very clear that my account was accurate, that my account was mischaracterized by Professor Briffa in serious ways, and that nothing in his letters refutes my original claim that had a key dataset not been ignored, a very much less striking result would have been published. Professor Briffa now says he was reprocessing the data, but in 2009 he said “we simply did not consider these data at this time”. Neither explanation fits the known facts well.

I therefore stand by my story.

My original intention in mentioning this example, chosen from many in climate science of the same phenomenon, was to draw attention to the fact that non-publication of adverse data is not a problem confined to the pharmaceutical industry, but also occurs in government-funded, policy-relevant areas of academic science.

My recent Times column was on human monogamy:

The tragic death of an Indian minister’s wife and the overdose of a French president’s “wife” give a startling insight into the misery that infidelity causes in a monogamous society. In cultures like India and France, it is just not possible for men to reap the sexual rewards that usually attend arrival at the top of society. President Zuma of South Africa has four wives and 20 children, while one Nigerian preacher is said to have 86 wives. Chinese emperors used to complain of their relentless sexual duties. Why the difference?

As China’s one-child policy comes officially to an end, it is time to write the epitaph on this horrible experiment — part of the blame for which lies, surprisingly, in the West and with green, rather than red, philosophy. The policy has left China with a demographic headache: in the mid-2020s its workforce will plummet by 10 million a year, while the number of the elderly rises at a similar rate.

The difficulty and cruelty of enforcing a one-child policy was borne out by two stories last week. The Chinese film director Zhang Yimou, who directed the Beijing Olympics’ opening ceremony in 2008, has been fined more than £700,000 for having three children, while another young woman has come forward with her story (from only two years ago) of being held down and forced to have an abortion at seven months when her second pregnancy was detected by the authorities.

It has been a crime in China to remove an intra-uterine device inserted at the behest of the authorities, and a village can be punished for not reporting an illegally pregnant inhabitant.

My Times column, December 23, 2013:

There is a common thread running through many recent stories: paedophilia at Caldicott prep school and in modern Rochdale, the murders of Lee Rigby in Woolwich and by Sergeant Alexander Blackman in Afghanistan, perhaps even segregation of student audiences and opposition to the badger cull. The link is that people are left stranded by changing moral standards, because morality is always evolving.

My Times column on how earthlings communicate with life in space:

The Hubble telescope has revealed that Europa, a moon of Jupiter, has fountains of water vapour near one of its poles, which means its ocean might not always be hermetically sealed by miles-thick ice, as previously assumed.

Europa’s huge ocean, being probably liquid beneath the ice, has long been the place in space thought most favourable to life, so the prospect of sampling this Jovian pond for bugs comes a little closer. My concern is a touch more mundane. Who’s in charge of the response down here when we do find life in space?

My fellow Times writer the cricketer Ed Smith posed me a very good question the other day. How many of the people born in the world in 1756 could have become Mozart? (My answer, by the way, was four.) So here’s a similar question: how many Britons born in 1964, if educated at Eton and Balliol, could have achieved what Boris Johnson has achieved? It’s clearly not all of them; it’s probably not one; but it’s not a big number.

My point? There is little doubt that Boris Johnson is a highly intelligent man, notwithstanding his inability to cope with a radio ambush of IQ test questions, and that he would be a highly intelligent man even if he had not gone to Eton and Balliol — barring extreme deprivation or injury.

The recent burst of interest in IQ, sparked first by Dominic Cummings (Michael Gove’s adviser), and then by Boris, has been encouraging in one sense. As Robert Plomin, probably the world’s leading expert on the genetics of intelligence, put it to me, there used to be a kneejerk reaction along the lines of “you can’t measure intelligence”, or “it couldn’t possibly be genetic”. This time the tone is more like: “Of course, there is some genetic influence on intelligence but . . .”

My Times column was on the likely effect of weaker oil and gas prices on competitiveness:

The Chancellor is to knock £50 off the average energy bill by replacing some green levies with general taxation and extending the timescale for rolling out others. On the face of it, the possibility that global energy prices may start to fall over the next few years might seem like good political news for him, and some of the chicken entrails do seem to be pointing in that direction. There is, however, a political danger to George Osborne in such trends .

For Government strategists reeling from the twin blows of Ed Miliband’s economically illiterate but politically astute promise of an energy bill freeze and the energy companies’ price hikes, the prospect of lower wholesale energy prices might seem heaven sent. But in many ways it only exacerbates their problems, for the Government is right now fixing the prices we will have to pay for nuclear, wind and biomass power for decades to come. And it is fixing those prices at quite a high level.

My Times column is on immigration:

It looks as if David Cameron is determined not to emulate Tony Blair over European immigration. Faced with opinion polls showing that tightening immigration is top of the list of concerns that voters want the Prime Minister to negotiate with Europe, he is going to fight to keep a Romanian and Bulgarian influx out as Mr Blair did not for Poles in 2004. It is the ideal ground for him to pick a fight with Brussels.

One reason is that he now has more political cover on the issue of immigration. It is no longer nearly as “right wing” an issue as it once was, though popular enough with UKIP voters. Migration as a political issue seems itself to be migrating across the political spectrum from right to centre, if not left. Where once any kind of opposition to immigration was seen by left-wing parties and the BBC as just a proxy for racism, increasingly it is now a subject for real debate.

My review of Gregory Zuckerman's book The Frackers appeared in The Times on 23 November.

In the long tradition of serendipitous mistakes that led to great discoveries, we can now add a key moment in 1997. Nick Steinsberger, an engineer with Mitchell Energy, was supervising the hydraulic fracturing of a gas well near Fort Worth, Texas, when he noticed that the gel and chemicals in the “fracking fluid” were not mixing properly. So the stuff being pumped underground to crack the rock was too watery, not as gel-like as it should be.

Steinsberger noticed something else, though. Despite the mistake in mixing the fracking fluid, the well was producing a respectable amount of gas. Over a beer at a baseball game a few weeks later he mentioned it to a friend from a rival company who said they had had good results with watery fracks elsewhere. Steinsberger attempted to persuade his bosses to try removing nearly all the chemicals from the fluid and using mostly water. They thought he was mad since everybody knew that, while water might open cracks in sandstone, in clay-containing shale it would seal them shut as the clay swelled.

I know very little about what is being discussed inside the Third Plenum of the 18th Central Committee of the Chinese Communist party, which started at the weekend. The meeting is being held in secret — although one of the subjects to be discussed is said to be greater government transparency. About all we know is that “unprecedented” economic and social reforms are being discussed, including such things as rural property rights. But, to judge by a new wave of Mao worship, persecution of dissidents and reinforced censorship, political reform is less likely than economic.

In other words, the Chinese Communist Party is trying to continue pulling off the trick that has served it ever since Deng Xiaoping defeated the Gang of Four: more economic freedom combined with less political freedom. The people can choose any good or service they want — except their government. In many ways it has worked extremely well. In 1978 Maoism had left the country horribly poor: more than half the people of China tried to live on less than a dollar a day. Over the next nine years per capita income doubled, then doubled again over the nine years after that.

Many a left-leaning Western politician has been heard to muse about how much better we would grow if only we directed the market economy with the single-mindedness of the Chinese Communist Party. In the same way many a right-leaning Western politician has long admired the Singapore of Lee Kwan Yew on the same grounds. See, they mutter, a paternalistic government is best at generating economic prosperity.

This morning’s brief strike by the Fire Brigades Union, like the one last Friday evening, will, I suspect, mostly serve to remind those who work in the private sector just how well remunerated many in the public sector still are. The union objects to the raising of the retirement age from 55 to 60, on a generous final-salary pension scheme, with good job security. These are conditions few of those who work for private firms or for themselves can even dream of.

In my case, as somebody always on the look-out for under-reported good news stories, it also served to alert me to just how dramatic the fall in “demand” for firefighters has been. Intrigued by the strike, I looked up the numbers and found to my amazement that in 2011, compared with just a decade before, firefighters attended 48 per cent fewer fires overall; 39 per cent fewer building fires; 44 per cent fewer minor outdoor fires; 24 per cent fewer road-traffic collisions; 8 per cent fewer floods — and 40 per cent fewer incidents overall. The decline has if anything accelerated since 2011.

That is to say, during a period when the population and the number of buildings grew, we needed to call the fire brigade much, much less. Most important of all, the number of people dying in fires in the home has fallen by 60 per cent compared with the 1980s. The credit for these benign changes goes at least partly to technology — fire-retardant materials, self-extinguishing cigarettes, smoke alarms, sprinklers, alarms on cookers — much of which was driven by sensible regulation. Fewer open fires and fewer people smoking, especially indoors, must have helped too. There is little doubt that rules about such things have saved lives, as even most libertarians must concede.

My Times article on the storm that was to hit Britain on 28 October. In the event, four or five people died. Disruption to transport lasted only a few days.

If you are reading this with the hatches battened down, it may not be much comfort to know that 2013 has been an unusually quiet year for big storms. For the first time in 45 years no hurricane above Category 1 has made landfall from the Atlantic by this date, and only two in that category, confounding an official US government forecast of six to nine hurricanes in the Atlantic, three to five of which would be big. Even if the last month of the hurricane season is bad, it will have been a quiet year.

My Times article:

The real problem with nuclear power is the scale of it. After decades of cost inflation, driven mostly by regulations to redouble safety, 1600 megawatt monsters cost so much and take so long to build that only governments can afford to borrow the money to build them. Since Britain borrowing £14 billion extra is not really an option, then we have to find somebody else’s nationalized industry to do it, and guarantee high returns, as if it were a big PFI contract.

My Times column tackles an egregious example of regulation doing more harm than good:

Should shampoo be classified as a medicine and prescribed by doctors? It can, after all, cause harm: it can sting your eyes and a recent study found traces of carcinogens in 98 shampoo products. Sure, shampoo can clean hair if used responsibly. But what’s to stop cowboy shampoo makers selling dangerous shampoo to the young? Far too many shampoo manufacturers try to glamorize their product. Time for the state to step in.

My recent Times column on Moore's Law, technological progress and economic growth:

The law that has changed our lives most in the past 50 years may be about to be repealed, even though it was never even on the statute book. I am referring to Moore’s Law, which decrees — well, observes — that a given amount of computing power halves in cost every two years.

Robert Colwell, the former chief architect at Intel and head of something with a very long name in the US Government (honestly, you’d turn the page if I spelt it out, though now I’ve taken up even more space not telling you; maybe I will put it at the end), made a speech recently saying that in less than a decade, Moore’s Law will come to a halt.

My regular Times column from 26th September 2013:

Hypocrisy can be a beautiful thing when done well. To go, as Ed Miliband has done, within four years, from being the minister insisting that energy prices must rise — so uncompetitive green energy producers can be enticed to supply power — to being the opposition leader calling for energy prices to be frozen is a breathtaking double axel that would make Torvill and Dean envious.

Remember this is the very architect of our current energy policy, the man who steered the suicidally expensive Climate Change Act through Parliament; the man who even this week pledged to decarbonise the entire British economy (not just the electricity sector) by 2030, meaning that nobody will be permitted to heat their house with gas.

My review in The Times of Bill Bryson's fine book, "One Summer".

The summer of 1927 in the United States seems at first glance an odd subject for a book. We all know what happened in 1914, or 1929, but what’s so special about the 86th anniversary of one summer in one country? You can see the London publishers scratching their heads when Bill Bryson’s pitch arrived. Who was Jack Dempsey anyway? Is Babe Ruth a woman or a child? Isn’t Calvin Coolidge a cartoon character? Did Herbert Hoover invent the vacuum cleaner? Is Sacco and Vanzetti a department store? Charles Lindbergh: ah, we know who he is.

Actually, it’s a brilliant idea for a book, because Bryson now had the excuse to do what he does best: tell little biographies of historical figures, recount stories, paint word pictures and make witty asides. The result is a gripping slice of history with all sorts of reverberant echoes of today.

My Times column on how the world's oldest people are getting younger:

The two oldest men in the world died recently. Jiroemon Kimura, a 116-year-old, died in June in Japan after becoming the oldest man yet recorded. His successor Salustiano Sanchez, aged 112 and born in Spain, died last week in New York State. That leaves just two men in the world known to be over 110, compared with 58 women (19 of whom are Japanese, 20 American). By contrast there are now half a million people over 100, and the number is growing at 7 per cent a year.

For all the continuing improvements in average life expectancy, the maximum age of human beings seems to be stuck. It’s still very difficult even for women to get to 110 and the number of people who reach 115 seems if anything to be falling. According to Professor Stephen Coles, of the Gerontology Research Group at University of California, Los Angeles, your probability of dying each year shoots up to 50 per cent once you reach 110 and 70 per cent at 115.

My tribute to Ronald Coase, who has died aged 102, in The Times:

It’s not often that the ideas of a 102-year-old have as much relevance to the future as the past. But the death this week of Ronald Coase, one of the world’s most cited economists, comes at a time when there is lively debate about the very issue he raised: why neither markets nor government are panaceas.

Belatedly, here is my Times column from last week on the case of David Miranda's detention at Heathrow airport:

I am not usually an indecisive person who sees both sides of a question. But the case of Edward Snowden, Glenn Greenwald and David Miranda versus the British and US governments has me swinging like a weathervane in a squall between liberty and security. I can persuade myself one minute that a despicable tyranny is being gradually visited upon us by a self-serving nomenclatura and the next that proportionate measures were taken by the authorities to protect British citizens from irresponsible crimes perpetrated by self-appointed publicity seekers.

Such indecisiveness does not seem to afflict most of my fellow columnists elsewhere in the media. Sometimes, however, it is necessary to stick up for indecision. On behalf of those of us struggling to decide where justice lies, let me follow Boswell and “throw our conversation into [this] journal in the form of a dialogue”:

My Times column on the environmental effects of fracking and wind power:

It was the American senator Daniel Patrick Moynihan who once said: “You are entitled to your opinions, but not to your own facts.” In the debate over shale gas – I refuse to call it the fracking debate since fracking has been happening in this country for decades – the opponents do seem to be astonishingly cavalier with the facts.

Here are five things that they keep saying which are just not true. First, that shale gas production has polluted aquifers in the United States. Second, that it releases more methane than other forms of gas production. Third, that it uses a worryingly large amount of water. Fourth, that it uses hundreds of toxic chemicals. Fifth, that it causes damaging earthquakes.

Belated posting of my recent Times column on golden rice with links:

It was over harlequin ducks that we bonded. Ten years ago, at a meeting in Monterey, California, to celebrate the 50th anniversary of the discovery of the structure of DNA, I bumped into the German biologist Ingo Potrykus watching harlequin ducks in the harbour before breakfast. Shared enthusiasm for bird watching broke the ice.

I knew of him, of course. He had been on the cover of Time magazine for potentially solving one of the world’s great humanitarian challenges. Four years before, with his colleague Peter Beyer, he had added three genes to the 30,000 in rice to help to prevent vitamin A deficiency, one of the most preventable causes of morbidity and mortality in poor countries with rice-dominated diets. They had done it for nothing, persuading companies to waive their patents, so that they could give the rice seeds away free. It was a purely humanitarian impulse.

My latest column in The Times:

This is an article about a railway, but it begins with a wall; bear with me. I live not far from the line of Hadrian’s Wall and I often take visitors to marvel at its almost 1,900-year-old stones. That the Romans could build 80 miles of dressed stone fortification, 15ft high and 9ft wide, over crags and bogs with a small fort every mile, is indeed a marvel. It was one of Rome’s most expensive projects.

Yet I often ask visitors as they marvel: did it work? The answer is no. The Roman garrison was too strung out to defend the whole thing at once. Within 30 years it had been successfully attacked by the barbarians; within 40 it had been abandoned for a new wall in Scotland; when that did not work and Hadrian’s Wall became the boundary again, it was overrun by barbarians several times. Did it exclude or pacify the tribes of northern Britain? I doubt it.

My column in The Times on healthcare costs:

Babies got cheaper this week. Twice. First, Belgian scientists announced that their new method has the potential to cut the costs of some in-vitro fertilisation treatments from £5,000 to below £200. Their cut-price recipe requires little more than baking soda and lemon juice in place of purified carbon dioxide gas to maintain acidity when growing an embryo in a lab before implanting it.

Second, a baby called Connor was born after 13 of his parents’ embryos had their genomes analysed using next-generation DNA-sequencing techniques in an Oxford laboratory. Only three of the embryos were found to have the right chromosome number, and one of these “normal” embryos was then implanted in his mother. This new approach, made possible by the rapidly falling cost of DNA sequencing, promises to cut the number of failures during IVF, reducing both cost and heartache.

My Times column:

Exciting as Britain’s latest shale gas estimate is — 47 years’ supply or more — it pales beside what is happening in the United States. There shale gas is old hat; the shale oil revolution is proving a world changer, promising not just lower oil prices worldwide, but geopolitical ripples as America weans itself off oil imports and perhaps loses interest in the Middle East.

One of the pioneers of the shale gas revolution, Chris Wright, of Liberty Resources, was in Britain last month. It was he and his colleagues at Pinnacle Technologies who reinvented hydraulic fracturing in the late 1990s in a way that unlocked the vast petroleum resources in shale. Within seven years the Barnett shale, in and around Forth Worth, Texas, was producing half as much gas as the whole of Britain consumes. And the Barnett proved to be a baby compared with other shales.

My column in The Times:

Preventing cancer is proving a lot easier than curing it. The announcement that the NHS will fund five-year courses of the drugs tamoxifen or raloxifene for healthy women who are genetically predisposed to get breast and ovarian cancer is overdue. The US has been doing “chemo-prevention” for some time and clinical trials have confirmed that the benefits comfortably outweigh the side-effects. Tens of thousands of deaths a year could be averted.

This is another incremental advance in the prevention of cancer that began with the gradual recognition (resisted, ironically, by some of those fighting pesticides in the late 1950s) that tobacco smoke was a chief cause of lung cancer. Mainly thanks to such prevention, along with early diagnosis, surgery and some treatments, deaths from cancer, adjusted for age, are falling.

My column in the Times on 20 June 2013:

In the Energy Bill going through Parliament there is allowance for generous subsidy for a huge push towards burning wood to produce electricity. It’s already happening. Drax power station in Yorkshire has converted one of its boilers to burn wood pellets instead of coal; soon three of its six boilers will be doing this and the power station will then be receiving north of half a billion pounds a year in subsidy. By 2020, the Government estimates, up to 11 per cent of our generating capacity will be from burning wood.

My article in the Times on 13 June 2013

‘We are as gods and have to get good at it,” the Californian ecologist and writer Stewart Brand said recently. Worldwide there has been a sea change in the ecological profession. These days most ecologists recognise that there is no such thing as a pristine wilderness and that the best biodiversity is produced by active management to control some species and encourage others.

My Times column here.

I have a confession to make. Last week I held a meeting with representatives of three organisations and offered to raise an issue for them in the House of Lords. They claimed they were charities seeking a smidgin of funding to push forward promising research on a squirrel-pox vaccine, which might help to save the red squirrel from extinction in this country.

Now I begin to wonder if these three charming people were actually disguised investigative reporters who were trying to add my name to that of my three fellow peers who were splashed over the front page of The Sunday Times. Or perhaps they were from a front for the Chinese People’s Liberation Army. (Tony Blair apparently spoke at an event hosted by a front for the latter.) I never checked their credentials or frisked them for hidden cameras.

Update: I have added a reply to a critic of the article below.

I have an article in the Times on the implications of a new estimate of climate sensitivity:

There is little doubt that the damage being done by climate-change policies currently exceeds the damage being done by climate change, and will for several decades yet. Hunger, rainforest destruction, excess cold-weather deaths and reduced economic growth are all exacerbated by the rush to biomass and wind. These dwarf any possible effects of worse weather, for which there is still no actual evidence anyway: recent droughts, floods and storms are within historic variability.

I have a column in the Times on bitcoins and their implications for private money

Bitcoins — a form of digital private money — shot up in value from $90 to $260 each after Cypriot bank accounts were raided by the State, then plunged last week before recovering some of their value. These gyrations are symptoms of a bubble. Just as with tulip bulbs or dotcom shares, there will probably be a bursting. All markets in assets that can be hoarded and resold — as opposed to those in goods for consumption — suffer from bubbles. Money is no different; and a new currency is rather like a new tulip breed.

Yet it would be a mistake to write off Bitcoins as just another bubble. People are clearly keen on new forms of money safe from the confiscation and inflation that looks increasingly inevitable as governments try to escape their debts. Bitcoins pose a fundamental question: will some form of private money replace the kind minted and printed by governments?

This is a version of an article I published in The Times on 27 March:

The east wind could cut tungsten; the daffodils are weeks behind; the first chiffchaffs are late. It’s a cold spring and the two things everybody seems to agree upon are that there’s something weird about the weather, and it’s our fault. Both are almost certainly wrong.

I have the following article in the Times on 15 March:

Move over shale gas, here comes methane hydrate. (Perhaps.) On Tuesday the Japanese government’s drilling ship Chikyu started flaring off gas from a hole drilled into a solid deposit of methane and ice, 300 metres beneath the seabed under 1000 metres of water, 30 miles off the Japanese coast.

I have an op-ed in the Times on how even a global optimist can foresee absolute as well as relative decline for Europe if it continues to emulate the Ming Empire:

A "rational optimist" like me thinks the world will go on getting better for most people at a record rate, not because I have a temperamental or ideological bent to good cheer but because of the data. Poverty, hunger, population growth rates, inequality, and mortality from violence, disease and weather - all continue to plummet on a global scale.

But a global optimist can still be a regional pessimist. When asked what I am pessimistic about, I usually reply: bureaucracy and superstition. Using those two tools, we Europeans seem intent on making our future as bad as we can. Like mandarins at the court of the Ming emperors or viziers at the court of Abbasid caliphs, our masters seem determined to turn relative into absolute decline. It is entirely possible that ten years from now the world as a whole will be 50 per cent richer, but Europeans will be 50 per cent poorer.

I have an opinion article in The Times today:

Never has an undercover video sting delighted its victims more. A Greenpeace investigation has caught some Tory MPs scheming to save the countryside from wind farms and cut ordinary people's energy bills while Lib Dems, Guardian writers and Greenpeace activists defend subsidies for fat-cat capitalists and rich landowners with their snouts in the wind-farm trough. Said Tories will be inundated with fan mail.

Yet, for all the furore wind power generates, the bald truth is that it is an irrelevance. Its contribution to cutting carbon dioxide emissions is at best a statistical asterisk. As Professor Gordon Hughes, of the University of Edinburgh, has shown, if wind ever does make a significant contribution to energy capacity its intermittent nature would require a wasteful "spinning" back-up of gas-fired power stations, so it would still make no difference to emissions or might make them worse.

The Times has published my article on Northumberlandia today.

The Times published my op-ed on banking reform:

It is not yet clear whether the current rage against the banks will do more harm than good: whether we are about to throw the baby of banking as a vital utility out with the bathwater of banking as a wasteful casino. But what is clear is that the current mood of Bankerdämmerung is an opportunity as well as a danger. The fact that so many people agree that some kind of drastic reform is needed, all the way along a spectrum from Milibands to mega-Tories, might just open the window through which far-reaching reform of the financial system enters.

All the actors involved bear some blame. First, investment bankers and the principals in financial companies that cluster around them have trousered an increasing share of the returns from the financial markets, leaving less for their customers and shareholders, while getting "too big to fail", so passing their risks to taxpayers.

I wrote the following op-ed in The Times (behind a paywall) on 2 July.

As I cowered in my parked car in a street in Newcastle last Thursday, nearly deafened by hail on the roof of the car, thunder from the black sky and shrieking girls from the doorway of a school, a dim recollection swam into my mind. After inching back home slowly, through the flooded streets, I googled to refresh the memory. On 23 March this year, the Meteorological Office issued the following prediction:

"The forecast for average UK rainfall slightly favours drier-than-average conditions for April-May-June as a whole, and also slightly favours April being the driest of the 3 months. With this forecast, the water resources situation in southern, eastern and central England is likely to deteriorate further during the April-May-June period."

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.
