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.
