Cacophony

This morning, Emily, my mother, and I all woke to what sounded like somebody upstairs using a jackhammer on a hardwood floor. The whole house was vibrating, saturated with squealing and rattling noises.

A few minutes of pyjama-clad inquiries led me to the neighbour involved with the noise: “Oh, we’re just cutting some beams in the basement.”

Brain-thoughts, at that moment: “First thing in the morning? On a Saturday? With what sounds like an misfiring chainsaw?”

Promises of ‘just a few more minutes’ secured, back-to-bed trundling.

Brain-thoughts, just before returning to sleep: “Those aren’t the beams holding up this building, are they?”

Oh, it is too hot here…

Is it ethical to fly?

Continuing our long debate, here is another entry.

It seems to me that there are four possible long-term outcomes of the conflict between preventing climate change and travelling long distances quickly:

  1. We come up with a way to keep flying without doing too much climatic harm. This could be sequestration of carbon from biomass, it could be carbon neutral fuels, it could be something unanticipated.
  2. We come up with another transport technology that is carbon neutral and just as good or almost as good as flying, such as very high speed trains.
  3. We cannot reconcile long-distance high-speed travel with the need to mitigate, so we essentially stop doing it. A few people are still able to get from New York to London in a day, but it becomes out of almost everyone’s reach.
  4. We cannot reconcile long-distance high-speed travel with the need to mitigate, so we choose not to mitigate and wreck the planet.

How does the choice to fly look, in relation to each possibility?

  1. It’s not your fault you lived in the era before green flying was possible. That said, it may have been immoral to choose a mode of transport you knew to be (a) unsustainable and (b) harmful to others. It may be laudable or morally necessary to minimize flying and/or compensate for your impact by purchasing offsets.
  2. It’s not your fault you lived in the era before non-flight green travel was possible. That said, it may have been immoral to choose a mode of transport you knew to be (a) unsustainable and (b) harmful to others. It may be laudable or morally necessary to minimize flying and/or compensate for your impact by purchasing offsets.
  3. Again, you are on the hook for choosing an unsustainable option – specifically, one that had to be harshly curtailed in the future. Of course, if you are (a) selfish and (b) desirous of seeing the world, the danger that flying will be either restricted or far more expensive in the future creates an incentive to do a lot of it now.
  4. Flying was hardly a laudable thing to do, but it probably didn’t affect the outcome. Once we get into a runway climate change situation, it doesn’t matter much whether emissions in year X were Y megatonnes or 1.5Y megatonnes.

The larger question of whether future outcomes affects the morality of present decisions must also be contemplated. It does seem a bit odd to say that an action in 2007 was right or wrong as a consequence of technologies developed later. This post really cannot provide any answers to these questions – though my position remains that virtually all flying taking place at present is immoral – but perhaps it will provide a new way to consider things.

Fishing and restraint

Colourful leaves, botanical garden

Research being done off Lundy Island, in the United Kingdom, shows how quickly some marine ecosystems can begin to recover when fishing is discontinued. A five year old marine protected zone has resulted in the lobster population increasing sevenfold, as well as benefits to other species. This is consistent with the kind of larger scale recoveries that took place during the world wars, when the need for merchant ships and the dangers of war prevented most fishing fleets from operating.

It makes a person wonder what would be involved in producing a genuinely sustainable national fishery (trying to do the same in the open ocean is probably impossible for the foreseeable future, given the sheer number of unapologetically rapacious national fleets). One idea that comes to mind is this:

  1. Ban all imports. This will ensure that all fish being sold were caught under the sustainable approach.
  2. Restrict all fishing equipment (except safety equipment) to that which was available at the height of the age of sail. That means no diesel engines, no fish aggregating buoys, no satellite navigation, etc.
  3. Set catch quotas at a level where marine ecosystems as a whole remains vibrant and robust.

This would make fish dramatically more expensive, probably reducing consumption considerably. Arguably, it would actually increase employment in the industry. It would also make the industry rather more interesting to those both within and without it. Fishing from wooden tall ships has a lot more aesthetic appeal and romance than smashing the ocean floor and stripping the sea with freezer trawlers.

Of course, the above is supremely unlikely to ever happen. The question, then, is whether we will ever be able to come up with a mechanism that provides society with fish in an ethical and sustainable way, or whether we will keep plundering the resource, earning poorer and poorer catches, until we must be satisfied with whatever worms and jellyfish remain.

How politicians think

The Oil Drum has an interesting post on the psychology of leaders, arguing that their mindset has important consequences in relation to how they evaluate long-term questions like the future of hydrocarbon resources. The argument there is being made about Peak Oil, but it could just as well be applied to climate change:

Our leaders base decisions on lawyer thinking.

The outcome of a trial is not based on the facts; it is based on what they can convince the jury the facts might be. Likewise the outcome of an election is not based on facts; it is based on what they can convince the electorate the relevant facts, issues and threats might be.

Politicians do not deal in facts. They deal in perception. After years of working this way it becomes a framework in which they think.

The basic point is similar to the old joke about how public figures use statistics rather as drunkards use lamp posts: for support rather than illumination. Furthermore, the awareness that other politicians and politically active groups and individuals will use statistics in this way somewhat debases numerical evidence as a form or empirical awareness about the world.

Another important point is made about the differences between political and objective reality:

Politicians tend to inherently believe that the outcome of an event will depend on people’s perceptions and beliefs about that event. Politicians have very little experience with situations where objective reality is more important to outcome than the subjective perception of the reality.

This tendency is especially damaging when it comes to climate change. Because it progresses at an uncertain rate, it may well be that climate changes slowly while the perceptions of most people remain fairly stable, then changes too quickly for anything low-cost and effective to be done. On a problem characterized by uncertain time frames and potentially strong feedback effects, we need to get out in front of the issue, rather than being led by public or elite political opinion.

Pigs eat more fish than all of Japan

Apparently, 17% of wild-caught fish ends up getting fed to livestock. That’s pretty astonishing, given the increasingly dire state of global fish stocks, and it underscores the way in which most modern agriculture is fundamentally unsustainable.

As long as it is dependent on outside inputs where the supply is growing scarcer, it won’t be a mechanism for feeding humanity indefinitely.

Much better to leave those fish in the sea or, failing that, at least feed them to people.

US solar moratorium

What is to be done when people are plowing ahead with new coal power plants, despite the threat of climate change, and people are simultaneously forgetting about the expense, risk, and contamination associated with nuclear power? Impose a two-year moratorium on new solar projects, clearly. This at a time when we have eight years or so to stabilize total global emissions, before starting a long and deep decline – from over thirty gigatonnes per year to under five, within the lifetime of those now starting to ponder retirement.

Clearly, environmental issues relating to solar power stations need to be considered – just as bird strikes as so forth must be considered in relation to wind. That being said, a moratorium on the technology at the same time as oil sands and shale oil production are ramping up seems like hypocrisy.

Summer streets

For three Saturdays in August, New York City will be making six miles worth of city streets exclusively the domain of bikes and pedestrians. It’s an impressive undertaking, and a good method for making people think twice about their assumption that streets exist for the sake of drivers. For a long time, city dwellers have mostly assumed the roadways to be the exclusive territory of two-ton steel beasts. Taking them back is a step towards more cohesive communities, as well as a lower-carbon future.

If feasible, I would love to take the train down and have a look.

Overfishing and the EU

Long-time readers will remember the saga of the ‘fish paper’ – my research piece on the sustainability and legality of European Union fisheries policy in West Africa, eventually published in the MIT International Review.

Fisheries being an area of acute concern for me, I was gratified to see an unusually hard-hitting column in this week’s Economist about fish and the EU. It argues that EU goverments have shown “abject cowardice” in relation to their fishers for years. Meanwhile, overcapacity and unsustainable quotas have put the industry into a “suicidal spiral.” The article reports straightforwardly that: “More subsidies would reduce the already slim chance that Europe will ever have a sustainable fishing industry.”

I have argued previously that fishing should never be subsidized. There are far too many dangers of people selfishly exploiting a common good even without them. Indeed, I don’t have much hope when it comes to the long-term viability of world fisheries. That being said, if more people develop the understanding and candour displayed in this article, perhaps the madness can eventually be brought to heel.

Fuel cells are a pipe dream

Seven reasons why hydrogen fuel cell cars will never be a commonly deployed technology:

  1. You get hydrogen by cracking hydrocarbons or electrolyzing water. In either case, you are better off cutting out the hydrogen production step. You can burn the hydrocarbons directly (or make liquids from solid ones) and you can use the electricity to drive electric vehicles. Pretty much any time you make hydrogen, you are using up a better fuel.
  2. Cooling and compressing hydrogen for storage takes a lot of energy. Even liquid hydrogen has less energy per litre than gasoline.
  3. We would need to build an infrastructure of hydrogen liquification stations and pipelines.
  4. Storing enough hydrogen to travel a decent distance is difficult.
  5. Arguably, storing that quantity of hydrogen in a car is quite dangerous.
  6. Fuel cells are very expensive, partly because they require platinum catalysts. They are also relatively fragile.
  7. Fuel cells that produce water as a by-product might have trouble in freezing cold conditions.

Granted, a few of these factors might change. We might develop an ideal system for storing hydrogen or develop fuel cells with cheaper catalysts. Even so, the number of objections is large. Forced to bet, my guess for the ground transport of the future is electric vehicles and plug-in hybrids for urban areas and biofuel or coal-to-liquid powered vehicles for long-distance travel.

On evolution

The other day, I was reading about how flowers have evolved to attract the right sort of pollinators and encourage those creatures to carry their gametes to other flowers. They thereby attain the benefits of sexual reproduction (primarily the generation of novelty) without the need for locomotive capabilities. Other plants manipulate animals into disperse their seeds, as well as not eating their vital components, at least before the plants have had the chance to reproduce. Sometimes it is extremely intricate: peppers that want their seeds being eaten by birds (who will not digest them) rather than mammals (who will) have developed sophisticated chemical deterrents, specially shaped to bond to only the right sort of receptors.

Thinking back on it today, I was struck by just how impoverished any understanding of biology prior to understanding evolution must have been. It is rather saddening that some people have missed the boat, and tragic that some are trying to put others in the same position. Evolution isn’t something you ‘believe in’ or not; it is something you understand to a greater or lesser degree.
