Update: I failed to make clear that negative numbers in the drought severity index implies worse droughts. The two findings below contradict each other. Here is another "greening", of the Sahel:
Here's (belatedly) a piece I published in the Times last week.
British Gas is putting up the cost of heating and lighting the average home by up to 18 per cent, or about £200 a year. Indignation at its profiteering is understandable. But that can only be a part of the story: the combined profits of the big six energy supply companies amount to less than 1.5 per cent of your energy bill, according to the regulator, Ofgem.
My l atest Mind and Matter column in the Wall Street Journal is on 3D printing:
Serendipity works in curious ways. Earlier this month, on the day before I read news of the successful implanting of a synthetic windpipe grown with a patient's own cells, I happened to have lunch with a civil engineer who told me about the first use of a 3-D printer to print structures in concrete. The two technologies are very different, but as I read more about each, I soon found an eerie convergence.
Mark Lynas's new book The God Species contains a few pages that dispute my account of ocean acidification in particular. Mark kindly alerted me to this and asked for my reaction. The result was an exchange, which Mark has put up on his blog here, which I mirror here. I thank Mark for taking my arguments seriously and suggesting an exchange of ideas.
Lynas: In my book The God Species I take science writer Matt Ridley to task for downplaying the dangers of ocean acidification. He responded via email, and I to him. Here is the exchange. Matt's final short responses are also included, indented as 'Ridley2′. Square brackets are mine, for clarification.
Ridley: You say [in The God Species]: "Why not just admit candidly that whilst the human advance has been amazing and hugely beneficial, it has also had serious environmental impacts?" Answer: I do. Human beings have serious environmental impacts. I say so and I do not deny them. For example: "Take coral reefs, which are suffering horribly from pollution, silt, nutrient runoff and fishing - especially the harvesting of herbivorous fishes that otherwise keep reefs clean of algae." From megafaunal extinction to alteration of the composition of the atmosphere, I detail lots of changes wrought by humans. On both climate change and ocean acidification, I accept a human alteration of the environment as real. What I argue with is whether the negative impacts are always as great as claimed or the positive ones always as small as claimed. That's quite different from not admitting that there are impacts, serious and otherwise.
Brian Eno, the musician and writer, is more positive as a result of reading The Rational Optimist:
"That kind of marks the change I've felt in the past year or two. I wouldn't end an album like that now," he says. Drums Between the Bells has a loose, funky feel; it ends with the words, "Everything will be all right". Eno's new-found positivity - partly sparked by eco-thinker and Eno friend Stewart Brand's book Whole Earth Discipline and popular science writer Matt Ridley's The Rational Optimist - boils down to a belief that we've never had it so good.
"Cultures have a tendency to be pessimistic. The whole of the history of humanity is people going, 'It's all going to fall apart, my God it's looking terrible, we're not going to survive for another 20 years.' But, in fact, on average things have actually been getting better for thousands of years. It's like you're playing roulette in the casino and you keep winning and you think I've got to stop, this is not going to carry on. Well, it has been carrying on, by and large. Most of us in this country live a hundred times better lives than we would have done 100 years ago. So things are getting exponentially better for us, and we can't believe our luck, so there's a tendency to say, 'It can't go on'."
My latest Mind and Matter column for the Wall Street Journal is on the strange phenomenon of contagious cancer in dogs and Tasmanian devils, and whether it could happen to us. Elizabeth Murchison is speaking about this at the TED Global meeting in Edinburgh next week.
Frank Dikotter's fine -- and vital -- book on Mao's Great famine won the Samuel Johnson prize. But you can see a short film and a discussion about my book on the BBC Culture showhere(from minute 17.17 onwards). It's an honour to have made it to the shortlist.
Nic Lewis's discovery of a statistical alteration applied by the IPCC lends strong support to lukwarming
As most people know, I am a lukewarmer -- somebody who accepts carbon dioxide's full greenhouse potential, but does not accept the much more dubious evidence for net positive feedbacks on top, and who therefore thinks that a temperatuire rise of more than 2C in this century is unlikely.
My latest Mind and Matter column in the Wall Street Journal:
Driving home the other day it occurred to me that almost none of the greenery I could see-trees, garden shrubs, grass shoulders on the highway-was going to be used by humans for food, fuel, clothing or shelter.
New evidence has been published that the Great Barrier Reef is not in trouble from climate change. The effects of bleaching are short-lived and reversible. When I said this in my book, I was patronised from a great height by a bunch of marine biologists in New Scientist. Will they, and New Scientist, now apologise? As I keep saying, coral reefs are indeed under threat from man-made problems -- pollution, overfishing, run-off, but climate change is the least of their worries. Here's the abstract of Osborne et al's paper in PLOS One:
Coral reef ecosystems worldwide are under pressure from chronic and acute stressors that threaten their continued existence. Most obvious among changes to reefs is loss of hard coral cover, but a precise multi-scale estimate of coral cover dynamics for the Great Barrier Reef (GBR) is currently lacking. Monitoring data collected annually from fixed sites at 47 reefs across 1300 km of the GBR indicate that overall regional coral cover was stable (averaging 29% and ranging from 23% to 33% cover across years) with no net decline between 1995 and 2009. Subregional trends (10-100 km) in hard coral were diverse with some being very dynamic and others changing little. Coral cover increased in six subregions and decreased in seven subregions. Persistent decline of corals occurred in one subregion for hard coral and Acroporidae and in four subregions in non-Acroporidae families. Change in Acroporidae accounted for 68% of change in hard coral. Crown-of-thorns starfish (Acanthaster planci) outbreaks and storm damage were responsible for more coral loss during this period than either bleaching or disease despite two mass bleaching events and an increase in the incidence of coral disease. While the limited data for the GBR prior to the 1980's suggests that coral cover was higher than in our survey, we found no evidence of consistent, system-wide decline in coral cover since 1995. Instead, fluctuations in coral cover at subregional scales (10-100 km), driven mostly by changes in fast-growing Acroporidae, occurred as a result of localized disturbance events and subsequent recovery.
Here's what i wrote in my book.
Walter Russell Mead is always worth reading. Now he has written a two-part essay on Al Gore and the climate debate (part one; part two) that is, I think, very perceptive. It is angry, hard-hitting, and I don't agree with everything in it, but it somehow gets to to the core of the issue in a way that so much other commentary has not. This is the sort of old-fashioned polemic from somebody with historical perspective that has been lacking on this subject. Here's his conclusion:
The green movement's core tactic is not to "hide the decline" or otherwise to cook the books of science. Its core tactic to cloak a comically absurd, impossibly complex and obviously impractical political program in the authority of science. Let anyone attack the cretinous and rickety construct of policies, trade-offs, offsets and bribes by which the greens plan to govern the world economy in the twenty first century, and they attack you as an anti-science bigot.
The Rational Optimist is one of 13 books long-listed for the Royal Society Book prize for science books. If I make it to the shortlist, this will be my fifth time on this shortlist. (I have yet to win, though!)
My latest Mind and Matter column in the Wall Street Journal is on cancer and evolution by natural selection:
Last week the American Cancer Society reported that death rates from cancer are falling steadily, at an annual rate of about 1.9% in men and 1.5% in women. A study published this week by the University of Colorado found that most seniors who died after being diagnosed with breast cancer actually lived long enough to have died of something else.
Prevention explains much of the decline in cancer fatalities, especially the drop in smoking. As for treatment, the most promising new options harness the very force that makes cancer so stubbornly virulent in the first place: evolution.
Here is an op-ed I wrote for today's Australian newspaper:
POLLYANNA is a fool; Cassandra was wise. As a self-proclaimed "rational optimist" who argues that the world has been getting better for most people and that the future is likely to be better still, I am up against a deep prejudice towards pessimism that dominates the intelligentsia. As John Stuart Mill put it, "not the man who hopes when others despair, but the man who despairs when others hope, is admired by a large class of persons as a sage".
What is more, pessimism has become a hallmark of the Left, chiefly because it justifies activism. Once upon a time conservatives lamented the way the world had gone to the dogs since the golden age (and some still do), while socialists championed growth, technology and innovation to liberate the working class.
My latest Mind and Matter column for the Wall Street Journal is on how the future turns out:
Last month a crash dummy flew to 5,000 feet above ground level in a personal jet pack. The inventor, New Zealander Glenn Martin, has spent decades on the project and is ready to start selling the device for $100,000 each next year. The gasoline-driven machine can stay aloft for 30 minutes, thanks to what is, in effect, a pair of large leaf-blowers. A parachute provides partial reassurance if something should go wrong.
Mr. Martin's achievement is a reminder that, though we often underestimate the progress of a technology, sometimes we overestimate it. Back in the 1950s it seemed almost obvious that by the 21st century jet packs would be ubiquitous and routine aids to travel. They featured in sci-fi novels and comics and television series like "Lost in Space." A time-traveler who arrived from that era might be impressed by our Internet and mobile phones but amazed at our lack of working jet packs.
The Rational Optimist has been short-listed for the Samuel Johnson prize for the best non-fiction book of 2010.
From Andrew Bolt:
One German organic farm has killed twice as many people as the Fukushima nuclear disaster and the Gulf Oil spill combined.
My latest Mind and Matter column at the Wall Street Journal is about the precautionary principle as exemplified by the German e coli outbreak, which has now killed 29. Less precaution about new technology might have meant fewer deaths:
A technology that might have prevented contaminated produce from infecting thousands of Germans with E. coli was vetoed-by Germany-11 years ago for use in the European Union. Irradiating food with high-voltage electrons is a process that can kill bacteria on or in solid objects, just as pasteurization can kill them in liquid foods.
I have an article in The Conversation, an Australian idea forum:
I missed this news last month. For the second time in history, human beings have eradicated a disease altogether. This time it is rinderpest, which people cannot get, only cattle so it's not such big news as smallpox or (soon?) polio.
My latest Mind and Matter column in the Wall Street Journal is about what happens when hoaxers own up and nobody believes them. In the interest of space, I had to leave on the cutting room floor my favourite, though fictional, example. In The Life of Brian, Brian insists he is not the Messiah. A woman in the crowd then shouts: ``Only the true Messiah denies his divinity!''
Here's the column:
I have written the following review of Tim Harford's book Adapt, for Nature magazine:
Charles Darwin's big idea - that blind trial and error can progressively build a powerful simulacrum of purposeful design - got pigeonholed under biology. Yet it always had wider implications in economics, technology and culture. Darwin probably drew some elements of his bottom-up thinking from the political philosophers of the Scottish enlightenment, notably Adam Smith and Adam Ferguson. Biology is now returning the favour.
Books such as Steven Johnson's Where Good Ideas Come From (Allen Lane, 2010), Kevin Kelly's What Technology Wants (Viking Books, 2010) and Brian Arthur's The Nature of Technology (Free Press, 2009) are suffused with concepts from natural selection, as is my own, The Rational Optimist (Fourth Estate, 2010). Tim Harford's Adapt follows this tradition, focusing on the key role of failure - the 'error' in trial and error - in economic and social progress.
I have the following op-ed in today's Times:
Oxfam's chief executive, Dame Barbara Stocking, claimed this week in a BBC interview that there will "absolutely not be enough food" to feed the world's population in a few decades' time.
Such certainty about the future is remarkable, so I downloaded Oxfam's new "report" with interest. Once I got past the fundraising banners, I found a series of assertions that there is a food crisis caused by failures of government "to regulate, to correct, to protect, to resist, to invest, which means that companies, interest groups and elites are able to plunder resources and to redirect flows of finance, knowledge, and food". Oxfam is calling for "a new global governance" - effectively the nationalisation of the world food system.
A recent paper in the journal Nature concluded that species extinction caused by habitat loss is happening less than half as fast as usually estimated. The normal method for calculating rates of extinction assumes that doomed species merely cling temporarily to a shrunken patch of habitat, on their way to disappearing (an idea called "extinction debt"). Apparently, this isn't the case: Although a larger patch of habitat has more species in it, shrinking a patch does not lead to a proportional rate of species loss.
According to the authors of the study, the biologists Stephen Hubbell and Fangliang He, estimates of extinction rates based on the usual method are "almost always much higher than those actually observed." Though you need a big patch of forest to attract a rare species, you do not need such a big patch to retain it once it is there. Mr. Hubbell added: "The method has got to be revised. It is not right."
I sent this letter to the Financial Times:
Sir, Gideon Rachman ("In defence of gloomy columnists", May 24) is right to point out that terrible blips will still happen in an improving world. Another way of making the same point is that good news tends to be gradual, incremental and barely visible, while bad news almost by definition comes in sudden, newsworthy lumps: wars, crashes, disasters, epidemics. It is impossible to see a field of wheat growing, but easy to see it washed away by a flood.
My latest Mind and Matter column from the Wall Street Journal:
It turns out I was right to be sceptical about the Howarth study claiming that shale gas production produces more greenhouse gases than coal.
Ther's now a definitive study here thoroughly debunking Howarth and showing that shale gas results in 54% less GHG production. Howarth claimed that the gap between gas produced and gas sold indicated leakage. Instead it indicates usage in powering equipment.
This is Howarth's second big mistake. His first last year was to assume that coal mining produced no methane.
`Greener food and greener fuel' is the promise of Ensus, a firm that opened Europe's largest (£250 million) bio-ethanol plant at Wilton on Teesside last year - and has now shut it down for lack of profitable customers. This is actually the second shut-down at the plant - which takes subsidies and turns them into motor fuel - the first being a three-week refit to try to stop the stench bothering the neighbours.
Welcome to the neo-medieval world of Britain's energy policy. It is a world in which Highland glens are buzzing with bulldozers damming streams for miniature hydro plants, in which the Dogger Bank is to be dotted with windmills at Brobdingnagian expense, in which Heathrow is to burn wood trucked in from Surrey, and Yorkshire wheat is being turned into motor fuel. We are going back to using the landscape to generate our energy. Bad news for the landscape.
Now this is what I call magnificent writing in the sprit of Swift: Sean Corrigan riffs on peak oil, finite resources and the planet's carrying capacity:
It is much better to forget all that Sierra Club/WWF elitist, anti-mankind, horse manure about 'the call on the planet' exerted by us members of the 'plague species' and to take a little Bjorn Lomberg, a smattering of Julian Simon, and a riffle-through of Matt Ridley, regarding the minuscule size of the impact which our tiny little ilk - unimaginably outweighed by living forms we cannot even see - can really expect to exert on the vast, negatively-feedbacked rock which we inhabit-and to glory in the sustained quality of our response to the challenges which confront us, even under the far-from-ideal conditions under which we are usually asked to make it.
For example, just as an exercise in contextualisation, consider the following:-
Here's a piece I wrote for a Times supplement published yesterday in print, not available online.
In the twentieth century, the world population quadrupled. By the 1960s, it was growing at 2% a year. Yet, unlike the nineteenth century when the prairies, pampas and steppes had been brought under the plough, little new land was available to grow human food. Some in the western world began to suggest that food aid to the poor was only making the population problem worse. The ecologist Paul Ehrlich forecast famines `of unbelievable proportions' by 1975; the chief organizer of Earth Day, 1970, said it was `already too late to avoid mass starvation'; a professor in Texas said that by 1990 famines would be devastating `all of India, Pakistan, China and the Near East, Africa'.
Why did this not happen? Why was India a net exporter of food by the mid 1970s? Why did China never revisit the horrors of Mao's famines? Why has famine virtually disappeared from Africa except where foolish dictators cause it? Why has the growth rate of the world population halved to 1%?
