Global Warming: a contrarian view

Here are some contrarian thoughts:

Considering the persistence of carbon dioxide in the atmosphere (centuries), it could be that the warming we have seen through the 20th century is the accumulated effect of increased coal use in the 19th century to power the "industrial revolution". And the slowing down of warming seen in the past decade or so could be due to the move from coal to oil in the transition from the 19th to the 20th century a hundred years ago. And with increasing efficiency and use of natural gas instead of oil over the latter half of the 20th century, along with the curbing of ozone-destroying CFCs and powerfully warming HFCs, we should continue to see a moderation of the warming trend (at least of what can be attributable to anthropogenic carbon dioxide). However, that moderation would be threatened by continued renewed growth of coal use in China and India (to cheaply power their "development") and the continued burgeoning of animal agriculture (which, among other things, emits methane, a greenhouse gas with 20 times the warming effect of carbon dioxide, and drives the clearance of carbon-capturing forests), not to mention of the human population itself.

Ozymandias, the Wind Power King

I met a traveller from an antique land
Who said: “A vast and headless trunk of steel
Stands in the desert. Near it on the sands,
Half sunk, the shattered arms doth lie and peel
A twisted skin from antinatural bands
That tell its sculptor well those passions read
Which yet survive, stamped in this lifeless thing—
The hands that fed it and the hearts that bled.
And on the pedestal in letters spare:
‘My name is Ozymandias, wind power king:
Look on my work, ye mighty . . . and despair!’
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare,
The lone and level sands stretch far away.”

(with profuse apologies to Percy Bysshe Shelley)

Melatonin in autism spectrum disorders: a systematic review and meta-analysis

Aim  The aim of this study was to investigate melatonin-related findings in autism spectrum disorders (ASD), including autistic disorder, Asperger syndrome, Rett syndrome, and pervasive developmental disorders, not otherwise specified.

Method  Comprehensive searches were conducted in the PubMed, Google Scholar, CINAHL, EMBASE, Scopus, and ERIC databases from their inception to October 2010. Two reviewers independently assessed 35 studies that met the inclusion criteria. Of these, meta-analysis was performed on five randomized double-blind, placebo-controlled studies, and the quality of these trials was assessed using the Downs and Black checklist.

Results  Nine studies measured melatonin or melatonin metabolites in ASD and all reported at least one abnormality, including an abnormal melatonin circadian rhythm in four studies, below average physiological levels of melatonin and/or melatonin derivates in seven studies, and a positive correlation between these levels and autistic behaviors in four studies. Five studies reported gene abnormalities that could contribute to decreased melatonin production or adversely affect melatonin receptor function in a small percentage of children with ASD. Six studies reported improved daytime behavior with melatonin use. Eighteen studies on melatonin treatment in ASD were identified; these studies reported improvements in sleep duration, sleep onset latency, and night-time awakenings. Five of these studies were randomized double-blind, placebo-controlled crossover studies; two of the studies contained blended samples of children with ASD and other developmental disorders, but only data for children with ASD were used in the meta-analysis. The meta-analysis found significant improvements with large effect sizes in sleep duration (73min compared with baseline, Hedge’s g 1.97 [95% confidence interval {CI} CI 1.10–2.84], Glass’s Δ 1.54 [95% CI 0.64–2.44]; 44min compared with placebo, Hedge’s g 1.07 [95% CI 0.49–1.65], Glass’s Δ 0.93 [95% CI 0.33–1.53]) and sleep onset latency (66min compared with baseline, Hedge’s g −2.42 [95% CI −1.67 to −3.17], Glass’s Δ −2.18 [95% CI −1.58 to −2.76]; 39min compared with placebo, Hedge’s g −2.46 [95% CI −1.96 to −2.98], Glass’s Δ −1.28 [95% CI −0.67 to −1.89]) but not in night-time awakenings. The effect size varied significantly across studies but funnel plots did not indicate publication bias. The reported side effects of melatonin were minimal to none. Some studies were affected by limitations, including small sample sizes and variability in the protocols that measured changes in sleep parameters.

Interpretation  Melatonin administration in ASD is associated with improved sleep parameters, better daytime behavior, and minimal side effects. Additional studies of melatonin would be helpful to confirm and expand on these findings.

The output of this master clock is synchronized to 24 hours by the prevailing light-dark cycle. ... The cyclic levels of melatonin in the blood pass through the placenta and aid in the organization of the fetal SCN. In the absence of this synchronizing effect, the offspring exhibit neurobehavioral deficits. Melatonin protects the developing fetus from oxidative stress.” DOI: 10.1016/j.fertnstert.2014.06.014

Why Not Wind: an open letter

To whom it may concern:

This is a brief representation of the reasons industrial-scale wind is a destructive boondoggle that only fools – or worse – would approve.

Unlike “conventional” power sources, wind does not follow demand. As the Bonneville Power Authority in the Pacific Northwest of the USA has shown (www.wind-watch.org/pix/493), the relationship between load and wind generation is essentially random. That means that wind can never replace dispatchable sources that are needed to meet actual demand.

The contribution of wind generation is therefore an illusion, because the grid has to supply steady power in response to demand, and as the wind rises and falls, the grid maintains supply by relying on its already built-in excess capacity.

That is also why meaningful reductions in carbon emissions are not seen: because fuel continues to be burned in “spinning reserve” plants which are kept active to kick into electricity production when needed for meeting surges in demand or, now, drops in the wind. Denmark’s famously high wind penetration is possible only because it is connected to the large Nordic and German grids – so that Denmark’s wind power actually constitutes a very small fraction of that total system capacity. To make further wind capacity possible (despite a public backlash that has essentially stopped onshore wind development since 2003), Denmark is now building a connection to the Dutch grid.

Another reason that meaningful reductions in carbon emissions are not seen is that the first source to be modulated to balance wind is usually hydro. This is seen quite clearly in Spain, another country with high wind penetration: The changes in electricity from hydro are an almost exact inverse of those from wind (https://demanda.ree.es/generacion_acumulada.html). This is also seen in the USA’s Pacific Northwest (http://transmission.bpa.gov/business/operations/Wind/baltwg.aspx).

Finally, on systems with sufficient natural gas–powered generators, which can ramp on and off quickly enough to balance wind’s highly variable infeed, wind forces those generators to operate far less efficiently than they would otherwise. It is like stop-and-go city versus steady highway driving. According to several analyses (e.g., www.wind-watch.org/doc/?p=1568), the carbon emissions from gas + wind are not significantly different from gas alone and in some cases may be more.

And again, whatever the effect, wind is always an add-on. The grid must be able to operate reliably without it, because very often, and often for very long stretches of time, wind is indeed in the doldrums: It is not there.

And beware the illusion of “average” output. The fact is that any wind turbine or group of turbines generates at or above its average rate (which is typically 20%–30% of the nameplate capacity, depending on the site) only about 40% of the time. Because of the physics of extracting energy from wind, the rest of the time production approaches zero.

As an add-on, therefore, its costs are completely unnecessary and wasteful. And even if, by some miracle, it were a reliable, dispatchable, reasonably continuous source, its costs would still be enormous – not only economically, but also environmentally. Wind is a very diffuse resource and therefore requires a massive mechanical system to catch any useful amount. That means ever larger blades on ever taller towers in ever larger groupings. And the only places where that is feasible are the very places we need to preserve as useful agricultural land, scenic landscapes that are so important to our souls (and to tourism), and wild land where the natural world can thrive.

Besides the obvious damage to the land of heavy-duty roads for construction and continued maintenance, huge concrete platforms, new powerlines, and substations (while making no meaningful contribution to the actual operation of the grid) and the visual intrusion of 150-metre (500-ft) structures with strobe lights and rotating blades, there are serious adverse impacts from the giant airplane-like blades cutting through 6,000–8,000 square metres (1.5–2 acres) of vertical airspace both day and night: pulsating noise (including infrasound which is felt more than heard) that carries great distances and disturbs nearby residents (especially at night, when there is a greater expectation of – and need for – quiet and atmospheric conditions often augment the noise), even threatening their physical health, pressure vortices that kill bats by destroying their lungs, blade tip speeds of 300 km/h that also kill bats as well as birds, particularly raptors, many of which are already endangered, and vibration that carries through the tower into the ground with effects on soil integrity and flora and fauna that have yet to be studied.

In short, the benefits of industrial-scale wind are minuscule (if that), while its adverse impacts and costs are great. Its only effect is to provide greenwashing (and tax avoidance) for business-as-usual energy producers and lip-service politicians, while opening up to vast industrial development land that has been otherwise fiercely protected – most disturbingly by many of the same groups now clamoring for wind.

Industrial-scale wind is all the more outrageous for the massive flow of public money into the private bank accounts of developers. It is not surprising to learn that Enron established the package of subsidies and regulatory “innovations” that made the modern wind industry possible. Or that in Italy, the Mafia was an early backer of developers. It is indeed a criminal enterprise: crony capitalism, anti-environment rapaciousness, and hucksterism at its most duplicitous.

After decades of recorded experience, there is no longer any excuse to fall for it.

Betraying the Environment

Suzanna Jones writes at Vt. Digger:

There is a painful rift among self-described environmentalists in Vermont, a divide that is particularly evident in the debate on industrial wind. In the past, battle lines were usually drawn between business interests wanting to “develop” the land, and environmentalists seeking to protect it. Today, however, the most ardent advocates of industrial buildout in Vermont’s most fragile ecosystems are environmental organizations. So what is happening?

According to former New York Times foreign correspondent Chris Hedges, this change is symptomatic of a broader shift that has taken shape over many years. In his book “Death of the Liberal Class,” Hedges looks at the failure of the Left to defend the values it espouses – a fundamental disconnect between belief and action that has been corrupting to the Left and disastrous for society as a whole. Among other things, he argues, it has turned liberal establishments into mouthpieces for the power elite.

Historically, the liberal class acted as watchdog against the abuses of capitalism and its elites. But over the last century, Hedges claims, it has traded that role for a comfortable “seat at the table” and inclusion in “the club.” This Faustian bargain has created a power vacuum – one that has often been filled by right-wing totalitarian elements (think Nazi Germany and fascist Italy) that rise to prominence by ridiculing and betraying the values that liberals claim to champion.

Caving in to the seduction of careerism, prestige and comforts, the liberal class curtailed its critique of unfettered capitalism, globalization and educational institutions, and silenced the radicals and iconoclasts that gave it moral guidance – “the roots of creative and bold thought that would keep it from being subsumed completely by the power elite.” In other words, “the liberal class sold its soul.”

From education to labor to agriculture and environmentalism, this moral vacuum continues to grow because the public sphere has been abandoned by those who fear being labeled pariahs. Among the consequences, Hedges says, is an inability to take effective action on climate change. This is because few environmentalists are willing to step out of the mainstream to challenge its root causes – economic growth, the profit system, and the market-driven treadmill of consumption.

Hedges’ perspective clarifies a lot. It explains why so many environmental organizations push for “renewable” additions to the nation’s energy supply, rather than a reduction of energy use. It explains why they rant and rail against fossil fuel companies, while studiously averting their eyes from the corporate growth machine as a whole. In their thrall to wealthy donors and “green” developers (some of whom sit on their boards), they’ve traded their concern about the natural world for something called “sustainability” – which means keeping the current exploitive system going.

It also makes clear why Vermont environmental organizations like the Vermont Public Interest Research Group and the Vermont Natural Resources Council – as well as the state’s political leadership – have lobbied so aggressively to prevent residents from having a say regarding energy development in their towns. By denying citizens the ability to defend the ecosystems in which they live, these groups are betraying not only the public, but the natural world they claim to represent. Meanwhile, these purported champions of social justice turn their backs as corporations like Green Mountain Power make Vermonters’ homes unlivable for the sake of “green” energy.

Hedges’ perspective also explains why environmental celebrity Bill McKibben advocates the buildout of industrial wind in our last natural spaces – energy development that would feed the very economy he once exposed as the source of our environmental problems. Behind the green curtain are what McKibben calls his “friends on Wall Street,” whom he consults for advice on largely empty PR stunts designed to convince the public that something is being accomplished, while leaving the engines of economic “progress” intact. Lauded as the world’s “Most Important Environmental Writer” by Time magazine, McKibben’s seat at the table of the elites is secured.

In this way the “watchdogs” have been effectively muzzled: now they actually help the powerful maintain control, by blocking the possibility for systemic solutions to emerge.

Environmentalism has suffered dearly at the hand of this disabled Left. It is no longer about the protection of our wild places from the voracious appetite of industrial capitalism: it is instead about maintaining the comfort levels that Americans feel entitled to without completely devouring the resources needed (at least for now). Based on image, fakery and betrayal, it supports the profit system while allowing those in power to appear “green.” This myopic, empty endeavor may be profitable for a few, but its consequences for the planet as a whole are fatal.

Despite the platitudes of its corporate and government backers, industrial wind has not reduced Vermont’s carbon emissions. Its intermittent nature makes it dependent on gas-fired power plants that inefficiently ramp up and down with the vicissitudes of the wind. Worse, it has been exposed as a Renewable Energy Credit shell game that disguises and enables the burning of fossil fuels elsewhere. It also destroys the healthy natural places we need as carbon “sinks,” degrades wildlife habitat, kills bats and eagles, pollutes headwaters, fills valuable wetlands, polarizes communities, and makes people sick­ – all so we can continue the meaningless acts of consumption that feed our economic system.

Advocates for industrial wind say we need to make sacrifices. True enough. But where those sacrifices come from is at the heart of our dilemma. The sacrifices need to come from the bloated human economy and those that profit from it, not from the land base.

We are often told that we must be “realistic.” In other words, we should accept that the artificial construct of industrial capitalism – with its cars, gadgets, mobility and financial imperatives – is reality. But this, too, is a Faustian bargain: in exchange we lose our ability to experience the sacred in the natural world, and put ourselves on the path to extinction.

Preemptive Tu Quoque: a new rhetorical fallacy

A combination of the complex question (in which the question imputes an answer to another question that was not asked (“When will you stop being such a bully?”)) and projection (in which one thinks that everyone is just like oneself), the preemptive tu quoque asserts the imputed accusation, which is one the speaker is himself guilty of, i.e., the speaker projects his own sins onto his opponent, both forcing the opponent to defend himself and innoculating the speaker against the same charge because “Tu Quoque”, or “No: You are”, has even less force of argument.

Preemptive Tu Quoque is similar to simple Hypocrisy. It reveals more about the speaker than about the speaker’s subject.
