The problems of conducting science-by-press-release

Filed under: Environment, Media, Politics, Science — Tags: , , , — Nicholas @ 09:10

At sp!ked, Ben Pile explains why the first casualties in the climate change debate are usually the facts:

In plain sight of the fact that the melting was neither unexpected nor unprecedented, environmental journalists the world over picked up the story and ran with it. In the Guardian, Suzanne Goldenberg, wrote: ‘The Greenland ice sheet melted at a faster rate this month than at any other time in recorded history, with virtually the entire ice sheet showing signs of thaw.’

As I have noted elsewhere, Guardian journalists have a fetish for stories about melting ice. In September last year, following an unusually low measurement of Arctic sea-ice extent, Damian Carrington wrote: ‘Ice is the white flag being waved by our planet, under fire from the atmospheric attack being mounted by humanity.’ But the low measurement of sea ice that Carrington pointed to disagreed with at least five other continuous measurements of the Arctic, and was thus unreliable. This kind of over-reaction to scientific developments are facile attempts to turn science into stories of political intrigue. When images of the Arctic taken by US spy satellites were declassified in 2009, the headline of an article by Goldenberg and Carrington proclaimed that ‘the secret evidence of global warming Bush tried to hide’ had been ‘revealed’.

The rash of excited articles about the dying cryosphere caused some surprising corrective responses from voices within climate research. Malte Humpert from the Arctic Institute Centre wrote a stinging response to the headline histrionics. ‘The Greenland ice sheet, which is up to 3000+ metres thick, is not “melting away”, did not “melt in four days”, it is not “melting fast”, and Greenland did not “lose 97 per cent of its surface ice layer”.’ Humpert continued: ‘Most articles also exaggerated the importance of the melt event on global sea levels by explaining how sea levels would rise by up to 7.2 metres if the ice sheet were to melt.’

Similarly, Mark Brandon, a sea-ice scientist at the Open University, reproduced an interesting series of tweets and links to articles that showed the development of the current panic about ice, beginning with (alleged) comedian Marcus Brigstocke’s misconception of the story. To Brigstocke, an ‘unprecedented’ melt was the proverbial canary in the coal mine — a harbinger of doom. But as Brandon and his colleagues pointed out, it was a bit soon to be calling time on the human race. This was just weather.

Did China peak in 2008?

Filed under: China, Economics, Environment — Tags: , , , , , , — Nicholas @ 07:53

Walter Russell Mead wonders if the Chinese economy actually hit its peak in 2008 and will not be able to get back to that level of performance:

According to The Diplomat, the long term outlook is even more depressing. China will have to confront a series of structural challenges if it is to continue to achieve the kind of dynamic growth that lifted the country from economic backwater to emerging great power in just three decades.

The most obvious challenge is demographics. A RAND study observed that the proportion of the Chinese population of working age peaked in 2011 and began slowing this year. The share of the elderly population is rising. Healthcare and pension costs will soar as a result. So will labor costs. Investment and savings will diminish. In short, China may face the prospect, unknown in human history, of growing old before it gets rich.

The environment presents another dilemma. Like many rapidly industrializing economies, China sacrificed environmental protection at the altar of economic growth. But the effects of this approach have taken a toll: already, argues The Diplomat, ”Water and air pollution today cause 750,000 premature deaths and around 8 percent of GDP.” And as Via Meadia recently pointed out, the political costs of this approach are starting to mount as well. An outbreak of NIMBYism has forced many local officials to cancel major industrial projects as ordinary Chinese citizens demand an end to environmentally unsound development.

Of greater concern is that China has backed away from market reforms in the last decade and embraced a version of “state capitalism” that emphasizes the state far more than it does capitalism. But as state-run entities have become more powerful, their political backers — and financial beneficiaries — have an even greater stake in blocking attempts at reform.

Environmentalism versus ecology

Filed under: Environment, Politics — Tags: , , — Nicholas @ 10:09

An interesting interview with Dr. Patrick Moore:

Cotto: One of the gravest concerns you have cited with the modern environmentalist movement is its increasingly ideological nature. Some might say that this, in fact, is a positive development. How would you beg to differ?

Dr. Moore: Ideology is negative in so far as it tends to divide people into warring camps with no possible resolution. My late Greenpeace friend Bob Hunter suggested early on that in order for environmentalism to become a mass movement, it would have to be based on ideology, or as he called it “popular mythology,” because “not everybody can be a Ph.D. ecologist.” I have never accepted organized religion and note all the evils perpetuated in the name of “God is on our side” I do believe in just wars such as the armed struggle to end apartheid. But that was not based on religion but rather on human rights.

For example it has become part of environmental ideology, as stated by Bill McKibben in the current Rolling Stone, that the fossil fuel industries are “Public Enemy Number One.” Oil is particularly vilified as evidenced by high-profile campaigns to stop pipelines, drilling, tankers, oil sands, and anything else to do with producing or transporting oil. Oil is responsible for 36% of global energy and is therefore the most important source of energy to support our civilization. If it is the aim of “environmentalists” to stop fossil fuel production and use, end fracking, end coal mining, end the use of oil, then they are promoting a policy that would have disastrous consequences for human civilization and the environment. If we stopped using fossil fuel today, or by 2020 as Al Gore proposes, at least half the human population would perish and there wouldn’t be a tree left on the planet with a year, as people struggled to find enough energy to stay alive.

[. . .]

Cotto: In the past, you have said that human activity is not the only cause for climate change. What do you believe is the greatest contributing factor?

Dr. Moore: First, we don’t know precisely how the many factors affecting climate contribute and interact in producing the earth’s climate at any given time. The cause of the onset of Ice-Ages, one of which we are presently experiencing, is a puzzle we don’t fully understand. I explain in my presentations that as a scientist who is fully qualified to understand climate change, I seem dumber than the people who say they “know” the answers because I do not profess to know the future, especially of something so complicated as the global climate.

One thing is certain, there is no “scientific proof” as the term is generally understood, that human emissions are the main cause of climate change today. Even the IPCC only claims that it is “very likely” (a judgement, in their own words, not a proof) that human emissions are responsible for “most” of the warming “since the mid-20th century” (1950). Therefore they are not claiming that humans caused the 0.4C warming between 1910-1940, but they are claiming that we are the main cause of the 0.4C warming between 1970 and 2000. Yet they provide no opinion as to what did cause the warming between 1910-1940. There is a logical inconsistency here that has never been addressed. It is also important to note that the IPCC does not speak of “catastrophe”, that is left to the fanatics and perpetual doom-sayers.

Justification for Thomas Szasz?

Filed under: Health, Liberty, Science — Tags: , — Nicholas @ 13:54

An interesting post at the Hit and Run blog by Jacob Sullum:

Last year, I was surprised to see Allen Frances, who headed the panel that produced the current edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, tell Gary Greenberg: “There is no definition of a mental disorder. It’s bullshit. I mean, you just can’t define it.” This week Frances surprised me again, declaring in his contribution to a Cato Unbound debate about psychiatric coercion that “mental disorders most certainly are not diseases.” Rather, he says, they are “constructs” that may justify treating people against their will as “a last resort.” Go here for my response. But start with Jeffrey Schaler’s opening essay, where he lays out the Szaszian position on mental illness, which Frances, the lead editor of psychiatry’s bible, says he basically agrees with, although “Schaler and Szasz go way too far in their total rejection of any need ever for involuntary treatment.”

For you, is no Singularity

Filed under: Science, Technology — Tags: , , , , — Nicholas @ 11:25

Charles Stross linked to this article which points out that we’re not likely to experience the Singularity/Rapture of the Nerds/etc., and for good reasons:

Given that you are tech-savvy, by that point you have almost certainly come across the idea of the Singularity [1] as defended by futurists like Ray Kurzweil and Vernor Vinge. As a reminder, it is the notion that, when we are at last able to compile a smarter-than-human artificial intelligence, this AI will in turn manage to improve its own design, and so on, resulting in an out-of control loop of “intelligence explosion” [2] with unpredictable technological consequences. (singularists go on to predict that after this happens we will merge with machines, live forever, upload our minds into computers, etc).

What’s more, this seemingly far-future revolution would happen within just a few decades (2040 is often mentioned), due to the “exponential” rate of progress of science. That this deadline would arrive just in time to save the proponents of the Singularity from old age is just a weird coincidence that ought to be ignored.

Objection, your honor. As a scientist, I find the claim that scientific progress is exponential to be extremely dubious. If I look at my own field, or at any field that I am vaguely familiar with, I observe roughly linear progress — a rate that has typically been going on since as far back as the field’s foundation. “Exponential progress” claims are usually supported by the most bogus metrics, such as the number of US patents filled per year [3] (essentially a fashion utterly decorrelated from scientific progress).

And as somebody who does AI research, I find the notion of “intelligence explosion” to make exactly zero sense, for reasons reaching back to the very definition of intelligence. But I am not going to argue about that right now, as isn’t even necessary to invalidate the notion of the Singularity.

Drink some rainwater, go to jail

Filed under: Environment, Law, Liberty, USA — Tags: , , , — Nicholas @ 11:09

A 1925 law still applies in Oregon:

You just can’t make this stuff up. A man in Oregon is currently in jail serving a thirty day term – along with a $1500 fine – for collecting rainwater and snow melt on his own property for drinking and household use. You think I’m kidding? I’m not.

    Gary Harrington, the Oregon man convicted of collecting rainwater and snow runoff on his rural property surrendered Wednesday morning to begin serving his 30-day, jail sentence in Medford, Ore.

    “I’m sacrificing my liberty so we can stand up as a country and stand for our liberty,” Harrington told a small crowd of people gathered outside of the Jackson County (Ore.) Jail.

H/T to Jon, my former virtual landlord, who said “This is just a little weird […] But does the fact that I can see the point of the law — preventing people from messing with a watershed area, I guess — mean that I’ve consumed the nanny state kool-aid?”.

KittyCam project proves they are cute, cuddly … and deadly

Filed under: Environment, Randomness — Tags: , — Nicholas @ 08:40

Do you let your cat out into the great outdoors? If you’re fond of other small creatures, you may want to reconsider that policy:

Those cute kittens whose faces are peer from endless posts on Pinterest are actually predators, and a third of those trailed in a county in Georgia are wandering around outdoors capturing and killing other animals.

The army of assassins was discovered by folks from the University of Georgia and the National Geographic Society, who strapped video cameras around the necks of 60 cats to record their atrocities for a year in a project known as KittyCam.

[. . .]

“In Athens-Clarke County, we found that about 30 per cent of the sampled cats were successful in capturing and killing prey, and that those cats averaged about one kill for every 17 hours outdoors or 2.1 kills per week.

[. . .]

“If we extrapolate the results of this study across the country and include feral cats, we find that cats are likely killing more than four billion animals per year, including at least 500 million birds,” Dr George Fenwick, president of American Bird Conservancy, cried indignantly.

“Cat predation is one of the reasons why one in three American bird species are in decline.”

Overzealous copyright enforcement

Filed under: Law, Space, USA — Tags: , , , — Nicholas @ 09:36

Even copyright-free NASA footage can be taken down for copyright infringement. Brid-Aine Parnell at The Register explains the fast-trigger-finger-goof:

YouTube was a bit keen in the prosecution of copyright laws during NASA’s victorious Curiosity rover landing yesterday morning, booting the first video excerpt of the livestream off its site for infringing a news service.

NASA’s video coverage and pics are actually generally copyright-free, which made the overzealous bot takedown even more ironic as it pulled the video from the space agency’s channel for infringing on the rights of Scripps Local News.

The problem, which took a few hours to fix, was flagged by online magazine Motherboard, which spotted a message on the video declaring: “This video contains content from Scripps Local News, who has blocked it on copyright grounds”.

Reason.tv: What is an Astronaut’s Life Worth?

Filed under: Bureaucracy, Space, Technology, USA — Tags: , — Nicholas @ 10:28

“You’re saying that you’re going to give up four billion dollars to avoid a one in seven chance of killing an astronaut, you’re basically saying an astronaut’s life is worth twenty-eight billion dollars,” says astronautical engineer and author Dr. Robert Zubrin.

Zubrin, the author of a popular and controversial article in Reason‘s space-centric February 2012 Special Issue, argues that the risk of losing one of the seven astronauts who repaired and rescued the Hubble Space Telescope was well worth it. “If you put this extreme value on the life of an astronaut…then you never fly, and you get a space agency which costs seventeen billion dollars a year and accomplishes nothing.”

NASA’s role, according to Zubrin, should be in the pursuit of ambitious missions such as “opening Mars to humanity,” rather than a bloated, safety-obsessed bureaucracy. “The mission has to come first.”

Seeking Mars colonists for one way trip

Filed under: Space, Technology — Tags: , , , — Nicholas @ 09:00

Chris Brandrick on the first civilian recruitment drive for Martian colonization:

Just as NASA’s latest rover prepares to land on the surface of Mars, one Dutch company is looking to up the ante, with plans to send humans to the distant red planet. But before you sign up for travels to faraway lands, you may want to take note that the trip is a one-way deal, meaning you’ll never be able to return home to Earth.

Mars One, the ambitious company behind the planned mission, is hoping that a number of brave civilians will be willing to embark upon the mission to be the first to occupy the planet.

The company, founded by Bas Lansdorp, wants to send a number of humans to live on our neighboring planet indefinitely by 2023. The timeline for the mission will see Mars One send out a communications satellite in 2016, with a rover being sent in 2018 to find a suitable site for a settlement. Once the company finds a suitable location, it’ll send settlement units to Mars in 2020, which the existing rover will then set-up.

Once it gets the settlement established, Mars One hopes to send a small crew that would leave Earth in December of 2022, and arrive in April of 2023.

Visiting Mars would be fantastic, but I think I’ll wait until a return booking is possible.

Charles Stross: Where Moore’s Law and Koomey’s Law interact

Filed under: Science, Technology — Tags: , , — Nicholas @ 09:32

On his blog, Charles Stross explores the long-term implications of Moore’s Law (the doubling of computer circuits every two years) and Koomey’s Law (the energy efficiency of computers doubles every eighteen months):

A couple of basic physical rules underly the dizzying progress in electronics that we have seen over the past fifty years. Moore’s Law, attributed to Intel co-founder Gordon Moore, postulates that the number of transistors that can be placed on an integrated circuit of constant size doubles approximately every two years. Originally coined in 1965, Moore’s law has run more or less constantly ever since. It can’t continue indefinitely, if only because we’re getting close to the atomic scale; a silicon atom has a Van der Waals radius of around 200 picometres, and to build circuits that mediate electron transport we need discrete atomic-scale structures. It is not obvious that we can build electronics (or other molecular structures) with a resolution below one nanometre. So it’s possible that Moore’s law will expire within another decade.

Having said that, predictions of the imminent demise of Moore’s Law within a decade go back to the 1970s. And if we can’t increase the two-dimensional structure count on an integrated circuit, we may still be able to increase the number of structures by building vertically.

A newer, and more interesting formulation than mere circuit count is Koomey’s Law, proposed by Jonathan Koomey at Stanford University: that the energy efficiency of computers doubles every 18 months.

This efficiency improvement has held true for a long time; today’s high-end microprocessors require far less power per instruction than those of a decade ago, much less two or three decades ago. A regular ARM-powered smartphone, such as an iPhone 4S, is some 12-13 orders of magnitude more powerful as a computing device than a late 1970s-vintage Cray 1 supercomputer, but consumes milliwatts of power for computing (rather than radio) operations, rather than the 115 kilowatts of the Cray.

Taking them together, what do these two laws imply about the not-too-distant future?

US military faces recruiting nightmare

Filed under: Health, Military, USA — Tags: , , , , — Nicholas @ 09:17

Strategy Page outlines the most recent major problem the US military is facing: the bloat of potential recruits (not in numbers, but in individual mass). While the number of new recruits needed is declining, the pool of potential recruits to draw from has been declining even faster:

The problem is that Americans have, in the last two decades, become very fat and out-of-shape. There are 32 million male Americans of prime military age (17-24). But because of bad lifestyle choices, only 13 percent of them (4.2 million) are physically eligible for service. Each year, the armed forces have to recruit 150,000 new troops. The military is allowed to waive some physical or mental standards, and this means that only about 20 percent of those 32 million potential recruits qualify. Each year, recruiters have to convince about two percent of those eligible that they should join up. It’s a tough job, made worse by a generation that eats too much, exercises too little and doesn’t pay enough attention in school. You not only have to be physically fit enough to join, you also have to be smart enough and have no criminal record.

The enormous growth in computer entertainment, and subsequent massive reduction in exercise teenage boys get is the major reason for the body fat percentage crisis. As a result, one of the biggest problems American military recruiters have is unfit young Americans trying to enlist. Some 57 percent of potential recruits are not eligible because they do not score high enough on the aptitude test the military uses to see if people have enough education and mental skills to handle military life. Many of those who score too low do so because they did not do well at school. A lot of these folks have high IQs, but low motivation. Most of the remainder are not eligible for physical reasons. But get this; the most common physical disqualifier is being overweight. Nearly a third of the people of military age are considered obese. Many of these big folks are eager to join, and are told how much weight they have to lose before they can enlist. Few return light enough to sign up.

Computer gaming and other forms of indoor entertainment certainly bear some of the blame for the obesity problem, but other issues should also be included: helicopter parents who don’t dare let their kids go outside to play without full-time parental supervision, schools that have reduced or eliminated physical education for budget or liability reasons, and the huge increase in availability of low-priced, high-calorie fast foods.

The real reason behind the war on the humble plastic bag

Filed under: Environment, Liberty, Media, Politics — Tags: , , , , — Nicholas @ 08:54

Tom Bailey explains that the reasons we’ve been given for the renewed attacks on plastic bags are not the real reason for the ongoing struggle:

Individually, a plastic bag weighs about eight grams. In total, we use about 10 billion of them a year, adding up to around 80,000 tonnes of plastic bags. A large number, perhaps, but not when compared with total municipal waste. The total amount of household waste produced each year is 29.6million tonnes. This means that plastic bags make up a mere 0.27 per cent of what we all throw away every year. This percentage would become even smaller if we were to include commercial and industrial waste in our calculations.

The total amount of oil used to produce plastic bags is also exaggerated, considering that most plastic bags are made using naphtha, a part of crude oil that isn’t used for much else and would probably be burnt away otherwise.

So what’s going on here? Why the panic about a simple little bag? The assault on plastic bags is really an assault on consumerism. There is a prevailing view among the green and mighty that consumerism is bad. It is portrayed as being a modern-day vice, devoid of meaning, something which atomises society, corrupting us through crude materialism and distracting us from more important issues.

Plastic bags are an outward reflection of the ease with which people can buy goods and take them home. People now have the disposable income to enter a shop unexpectedly and buy a load of stuff, and plastic bags mean they can rest assured they they will have the means to carry their purchases. How often do people returning home from work decide, on a whim, to make a quick stop at Tesco Express to buy a few items of food? How frequently, perhaps on a journey past Oxford Street, are we drawn into a sale by a piece of attractive clobber? Such nonchalant consumption would be made more difficult, perhaps more expensive, without shops’ provision of handy, free plastic bags.

I guess I must be a puppet of “Big Plastic”, as I’ve posted about this issue a few times already.

Climate science as religion, complete with confession and absolution

Filed under: Environment, Media, Science — Tags: , , — Nicholas @ 08:41

In sp!ked, Rob Lyons explains why the “climate skeptic” credentials of Professor Richard A Muller don’t quite add up, and helpfully provides a guide to the larger skeptic community:

There has been much rejoicing among eco-commentators. Leo Hickman in the Guardian declared: ‘So, that’s it then. The climate wars are over. Climate sceptics have accepted the main tenets of climate science — that the world is warming and that humans are largely to blame — and we can all now get on to debating the real issue at hand: what, if anything, do we do about it?’ However, Hickman had to add ‘If only’. Apparently, while Muller is the right kind of sceptic, some pesky critics just won’t accept the ‘facts’. ‘The power of his findings lay in the journey he has undertaken to arrive at his conclusions’, suggests Hickman, but clearly some people don’t get it.

It sounds like a powerful argument: someone who has publicly taken a position for a few years, before putting up his hands and effectively saying: ‘You know what? I was wrong, and my fellow travellers were wrong, and we should just fall into line with the mainstream view.’ The conversion analogy is a good one. Here, instead of the unbeliever falling at the preacher’s feet and accepting Jesus into their lives, no longer able to resist the power of the Lord, we have the sceptic allowing the IPCC to drive out the devil of climate-change denial from within his soul.

Except, like many a modern faith healer’s performance, there’s something dodgy about this widespread interpretation. For starters, Muller was hardly what you would call a climate-change sceptic. By and large, he has been very accepting of the IPCC’s view of the problem of climate change. His claim to being a sceptic seems to relate to his acceptance that the famous ‘hockey stick’ graph, which was the centrepiece of the IPCC’s 2001 report and suggested that current temperatures are unprecedented, was simply the product of some sloppy science.

In spite of the media attempts to blacken the reputations of everyone who fails to fall into line with the IPCC’s orthodoxy, there are many different strains of disagreement with the official line:

But to a certain extent, this is all a false debate. There is no either/or. The leading climate sceptics all accept that humans have had some influence on the world’s climate. The argument is about how much human influence there is and what should be done about it.

Alarmists would argue that greenhouse-gas emissions are threatening to cook the planet and ultimately threaten humanity’s survival. At the very least, they see devastating destruction arising from global warming. For them, the only answer is the rapid decarbonisation of the world economy. Since the world is currently reliant on carbon-based fuels, this could mean an end to the drive for economic growth and the reorganisation of the economy and global politics. Anyone who disagrees is a ‘denier’. Some alarmists seriously suggest that debate should end now and anyone who continues to question the ‘consensus’ should be punished.

A few individuals aside, most climate sceptics think the world is moderately warmer than before, that humans have had some effect, but that most of the variation is natural and not particularly worrisome. Another band of sceptics — those who might be called ‘policy sceptics’, like Bjorn Lomborg and Roger Pielke Jr — broadly accept the IPCC’s view of temperature change and its causes. However, they think that the answer lies in devoting resources to technological development in the short term rather than a costly and probably futile attempt to decarbonise the world overnight. But even such policy disagreement is too much for the alarmists, who regularly pillory Lomborg in particular, yet it gets dressed up as ‘scientific fact’.

The BEST model: still science-by-press-release

Filed under: Environment, Media, Science — Tags: , , — Nicholas @ 09:02

Andrew Orlowski on the latest PR offensive by Dr Richard Muller of the Berkeley Earth Surface Temperature (BEST) project:

Richard Muller’s Berkeley Earth Surface Temperature (BEST) project, which began with goodwill from all corners of the climate debate, has made a series of bold announcements (without benefit of peer review) to the effect that global warming is definitely serious and definitely caused by humans. This has aroused derision among formerly supportive climate sceptics, caused an eminent climatologist to abandon the project, and even drawn criticism from generally alarmism-sympathetic media commentators.

Muller, professor of physics at UC Berkeley, is often regarded as a climate sceptic because he has frequently criticised the techniques used by climate scientists in the past and because he accepted funding for BEST from libertarian oil billionaire Charles Koch. When BEST launched in the wake of Climategate, it vowed to be “an independent, non-political, non-partisan group”, with Muller promising that “there will be no spin, whatever we find”. Critics of the existing temperature establishment, including well known sceptics Anthony Watts and Doug Keenan, welcomed it.

However each announcement has been aggressively trialled in the press not only before the peer review process had judged them ready for publication — which may not be a major issue — but also before anyone outside the BEST project could examine the papers at all. This requires the ordinary reader to take BEST’s accompanying press releases on blind faith — which is not a barrier for some journalists, but is far short of acceptable practice.
