Torture, psychology, and the law

Morty wants a treat

For the darkest day of the year, a couple of torture-related items seem appropriate. Firstly, there is this New York Times piece, which argues that senior officials from the Bush administration should be charged with war crimes, for authorizing and enabling torture. The editorial argues that there is no chance that prosecutions will be sought under an Obama administration, but that he ought to clarify the obligation of the United States and its agents to uphold the Geneva Conventions, as well as reverse executive orders that “eroded civil liberties and the rule of law.”

The prospect of high-level American decision-makers being put on trial for authorizing torture is so unlikely that it is a bit difficult to even form an opinion about it. At the same time, it is likely that nobody thirty years ago would have anticipated the trials at the International Criminal Tribunal for Rwanda (ICTR), International Criminal Tribunal for the former Yugoslavia (ICTY), or International Criminal Court (ICC). There is no clear reason for which high political office should be any impediment to being tried for war crimes, but it is very unclear how any such prosecutions would fare in the United States. It would certainly be seen as a ‘political’ act, and any connections with international law would likely be the targets for special criticism and scorn from some quarters.

The other story worth mentioning is an experiment conducted by Dr Jerry Burger, of Santa Clara University. It was a less intense re-creation of Milgram’s famous experiment on obedience to authority. Like Milgram, Burger found that a startling proportion of the population is willing to torture a fellow human being as part of a scientific experiment. This is when the only pressure placed upon the subject of the experiment is the authority of the actor pretending to conduct it. That naturally makes one nervous about what people would be willing to do when they felt an urgent and important issue justified it, as well as when far stronger sanctions could be brought against them if they did not proceed.

The nature and future of wind power

This Economist article discusses the history, technology, and future of wind power. It includes a fair bit of useful information, particularly about integrating wind into the broader energy system:

In addition, the power grid must become more flexible, though some progress has already been made. “Although wind is variable, it is also very predictable,” explains Andrew Garrad, the boss of Garrad Hassan, a consultancy in Bristol, England. Wind availability can now be forecast over a 24-hour period with a reasonable degree of accuracy, making it possible to schedule wind power, much like conventional power sources.

Still, unlike electricity from traditional sources, wind power is not always available on demand. As a result, grid operators must ensure that reserve sources are available in case the wind refuses to blow. But because wind-power generation and electricity demand both vary, the extra power reserves needed for a 20% share of wind are actually fairly small—and would equal only a few percent of the installed wind capacity, says Edgar DeMeo, co-chair of the 20% wind advisory group for America’s Department of Energy. These reserves could come from existing power stations, and perhaps some extra gas-fired plants, which can quickly ramp up or down as needed, he says. A 20% share of wind power is expected to raise costs for America’s power industry by 2%, or 50 cents per household per month, from now until 2030.

In 2007, 34% of the new electricity generation capacity that came online in the United States was in the form of wind turbines; China has doubled its capacity every year since 2004. 20% of Danish electricity already comes from wind, along with 10% in Spain and 7% in Germany. Given aggressive construction plans in Asia, North America, and Europe, wind power definitely looks like a technology with a big future.

Vaclav Klaus on climate change

Cars parked in Gatineau

Recently, Czech President Vaclav Klaus demonstrated the degree to which he deeply misunderstands the issue of climate change:

“Environmental issues are a luxury good,” Klaus added. “Now we have to tighten our belt and to cut the luxury.”

Global climate issues “are a silly luxury good,” he repeated.

Not only is maintaining a stable climate a fundamental requirement for human life and civilization, but it will be future generations who bear the majority of the pain if we fail to reduce emissions quickly. Far from being some unnecessary luxury, cutting greenhouse gas emissions is a vital moral requirement.

In Poznan, Al Gore did a much better job of explaining the ethical situation appropriately:

Very simply put, it is wrong for this generation to destroy the habitability of our planet and ruin the prospects of every future generation. That realization — that realization must carry us forward. Our children have a right to hold us to a higher standard when the future of all human civilization is hanging in the balance. They deserve better, and politicians who sit on their hands and do nothing to confront the greatest challenge humankind has ever faced.

Hopefully, that is a position that will rapidly becomore more widely held among politicians and the population at large.

Energy usage and the US Department of Defence

This article on space solar power (collecting energy from sunlight using one or more satellites in geostationary orbit, then beaming it down to Earth using microwaves) contains some interesting information on American military logistics in Iraq:

The armed forces are America’s single greatest consumer of oil. The Department of Defence delivers 1.6m gallons (7.3m litres) of fuel a day—accounting for 70% by weight of all supplies delivered—to its forces in Iraq alone, at a delivered cost per gallon of $5-20. It also spends over $1 per kWh on electric power (ten times the domestic civilian price) in battle zones, because electricity must often be provided using generators that run on fossil fuels.

This helps explain why militaries have such a keen interest in new energy generation and efficiency technologies.

The information on space solar power is also quite interesting. It actually seems to be a bit less infeasible than I thought, though the launching costs remain a very significant barrier.

Ottawan photographic evening

Police car in front of Parliament

Last night, I was at a photography book launch / fundraiser at the Ottawa School of Art. The event was a lot of fun, and I met some interesting people. I am considering taking a photography course there in January.

In any event, on account of spending half my evening enjoying the company of photographers and half my evening taking solitary photos of national monuments in the cold, I don’t have anything to say about climate change, cryptography, international relations, copyright law, or nuclear weapons right now.

Strangers and street photography

I have never been fond of photographing strangers, and my natural reticence has been enhanced as a result of a few people who responded badly. As a consequence, my photos generally include either friends, people who aren’t prominent in the image, or nobody at all. I make a bit of an exception for situations where people are clearly making a display of themselves (in costume, for instance), but generally avoid pointing my lenses at people I don’t know, even in public.

While I recognize the sense of this approach, it does make me feel as though my photos lack something that most street photographers manage to capture: specifically, the various moments that make up city life. Should I try to be bolder and produce some images like those in the photo.net ‘Street Photography’ tutorial?

Evidence of a positive climate change feedback in the Arctic

Piano at Raw Sugar

A study being presented at the annual meeting of the American Geophysical Union claims to have found the first concrete evidence of ‘arctic amplification’ – the phenomenon in which the loss of sea ice exposes water that reflects less sunlight than the ice did, thus causing further warming:

Climate-change researchers have found that air temperatures in the region are higher than would be normally expected during the autumn because the increased melting of the summer Arctic sea ice is accumulating heat in the ocean. The phenomenon, known as Arctic amplification, was not expected to be seen for at least another 10 or 15 years and the findings will further raise concerns that the Arctic has already passed the climatic tipping-point towards ice-free summers, beyond which it may not recover.

As with many of the other things happening in the Arctic, the phenomenon is not unexpected but the timing is. Partly, that reflects the imperfect (or totally absent) integration of feedback effects into climatic models.

As with so much other Arctic news, one can only hope that this will be a reminder of the urgency of mitigating greenhouse gas emissions. It is possible that doing so is more urgent than addressing the ongoing financial crisis and, from a long-term perspective, it is certainly a lot more important.

Carbon pricing and economic freedom

Post-Dion, it will take a bold politician to revive the idea of a carbon tax in Canada. One ironic consequence of that is that it is likely to produce more ‘command and control’ style environmental policies. Whereas an economy-wide carbon tax (or cap-and-trade scheme with auctioning) would encourage every individual decision-maker to examine the cost of reducing their greenhouse gas emissions, trying to achieve those reductions based on targetted government initiatives requires that political and bureaucratic decision-makers try to perform that analysis: trying to identify low-cost potential emissions reductions, as well as instruments through which they can be encouraged.

I have argued previously that just putting a price on greenhouse gas emissions is not sufficient to drive the change we need, because other market failures and economic structures need to be overcome. With that caveat expressed, it is more than a touch ironic that an anti-tax ‘free market’ ideology that rejects carbon pricing may lead to centrally planned solutions emerging, as opposed to market-directed ones.

A related irony concerns the timing of mitigation. As Joseph Romm has repeatedly pointed out, we have the opportunity today to begin the transition towards a low-carbon economy in a relatively voluntary way. Nobody needs to be banned from doing essential; rationing is not required. All we need are sensible economic instruments and accompanying policies, provided we get started right away. By contrast, if we squander the opportunity we have now, achieving the stabilization of the atmospheric concentration of greenhouse gasses will require that far more onerous burdens be placed on individuals. In short, today’s unhampered freedom to emit greenhouse gasses is inexorably linked to the necessity of sharply dimininished freedoms in the future.

Fatih Birol on peak oil

In an interview with British journalist George Monbiot, Fatih Birol, the chief economist of the International Energy Agency made the following predictions about when peak oil output for non-OPEC and OPEC states would be reached:

“In terms of non-OPEC [countries outside the big oil producers’ cartel]”, he replied, “we are expecting that in three, four years’ time the production of conventional oil will come to a plateau, and start to decline. … In terms of the global picture, assuming that OPEC will invest in a timely manner, global conventional oil can still continue, but we still expect that it will come around 2020 to a plateau as well, which is of course not good news from a global oil supply point of view.”

Coming from a representative of this particular organization, that is quite a surprising statement. Traditionally, the IEA has downplayed any suggestion that global oil output could peak before 2030. A peak in 2020 suggests that we have a lot less time than most firms and governments have been expecting to transition to a post-oil, post-gasoline, post-jet fuel future.

An early peak in oil output could have an enormous effect on both the development of the global economy and climate change. What effect it will have depends on many factors: three crucial ones being the timing of the peak, the severity of the drop-off in output afterwards, and the investment decisions made by states and firms. If we want to continue to produce enough energy to run a global industrialized society, and we also want to avoid the worst effects of climate change, we need to ensure that renewables (and perhaps nuclear) are the energy sources of the future, and that efficient means of energy storage are developed for vehicles.

Winter moods

Today’s sharp, dry cold makes for a nice contrast to yesterday’s Slowly Melting City. As much as you might think a brief return to fall weather, in the midst of winter, might be pleasant, it seems to be the case that once this city is well frozen, it does best to remain that way.

The special hazards of the melting city are the combination of speeding cars with deep, slush-filled pools, as well as wind-blown tiny droplets of water that threaten any lenses or electronic equipment not well stowed in bags. Taking photos in wind-blasted rain or wet snow is nearly impossible, provided you don’t have an assistant to carry around a beach umbrella for you. Walking to work yesterday, there were three points where I had to choose between wading through a sidewalk submerged in ten centimetres of muddy slush water, or jumping the barrier onto the roadway and making a mad dash around the pool while the flow of cars was interrupted by a red light. Each time, I decided to take the rapid roadway approach – a series of decisions which left me with dry feet and a bit more aerobic exercise.

One effect of the bus strike has been to make me much more aware of the weather. Essentially, that is on account of having to spend longer spans outside, and having no transport alternatives to walking when the weather suddenly changes. As such, I have been lugging around enough wool at most points in time that, should the need arise to re-clothe a sheared sheep, I would probably be able to do so.
