Morality of climate inaction

Happy Birthday Sasha W

One of the most interesting statements made at the climate change conference was Henry Shue’s moral categorization for inaction on climate change: he called it ‘the infliction of harm upon the defenceless.’ This, he said, is true independently from whether abrupt and harmful climate change scenarios arise. Given what we know, it is akin to forcing someone to play Russian Roulette: even if there is no bullet in the chamber, when the hammer falls, the imposition of the risk is immoral.

The idea of future generations being in a position of helplessness, relative to us, had not occurred to me before. Historical progress has generally involved increases in human capability. I suppose it is only now that we have the widescale ability to threaten vital biological systems that we stand to undermine whatever new capabilities our forebears will have, both technical and economic, by presenting problems insoluble even with future technology.

Scenarios like the disruption of the Thermohaline circulation circulation of the liberation of methane hydrate from the ocean floors definitely seem insoluble, even given vastly increased capability. Perhaps such arguments can help to generate the impetus in the minds of people and policymakers that will be required to move forward with GHG controls.

Climate conference concluded

Today’s climate change conference in Reading was most engaging. My notes on it are here. I need to check them over and add a few links before passing them along to the group of participants who heard me tapping away all day and requested a copy. Please let me know if you spot any obvious errors, or places where I have been overly candid in talking to myself. [Editorial comments are in square brackets.]

I skipped out on the conference dinner, as it was to be thirty Pounds. Now, I am off to Lee’s housewarming party.

Revitalized

Essentially back to back this evening, I had two of the best lectures since arriving in Oxford. It was a well-timed reminder of why it is so valuable to be here, and the kind of knowledge and people one can be exposed to in this environment.

The first speaker was Hilary Benn, appearing as part of the Global Economic Governance series. He is the Secretary of State for International Development in the current British Government. His speech took in everything from institutional reform at the World Bank to what should be done in Darfur. While he may have oversimplified a great deal at times, it was nonetheless refreshing to hear a government official saying some very sensible and progressive things about the role Britain should play in the world. During the question session, I asked him about his department’s policy position on West African fisheries. He advised me to write him a letter, and promised a detailed response. Thanks to an aid, I have the real email address of a British cabinet member in my pocket. I will come up with a cover letter that addresses the major points, then include a copy of the article in print in case he (or a staffer) wants more detail.

The second speaker, through the Strategic Studies Group, was Rear Admiral C.J. Parry. I spoke with him during dinner about his aviation experience (he actually flew a V-22 Osprey). His talk, in the capacity of Director General of Development, Concepts and Doctrine for the Ministry of Defence at Shrivenham, was a look forward into major strategic threats in the next thirty years or so. That said, it was a candid and engaging presentation that has sparked a lot of thought and debate – exactly what the mandate of OUSSG is to provide.

Sorry if this is all a bit breathless, but I suddenly feel as though I have a lot to do – and not just in terms of the thesis work I have been dreading.

PS. Both Kai and Alex are back, which adds to my sense of rejuvination. Likewise, the opportunity that has been afforded to see the friendly trio of Bryony, Claire, and Emily was most welcome. Indeed, seeing all members of the program has felt a bit like suddenly being surrounded by friends in Vancouver. Things with my new college advisor – Robert Shilliam – are also going well.

PPS. I have my first free Wadham high table dinner booked for tomorrow, as part of the Senior Scholarship.

Thin ozone year

One example that comes up again and again in the environmental literature is ozone depletion. It emerged as the unexpected effect of the use of a new class of chemicals. It required global regulation to check. And we seem to have succeeded in dealing with the problem, through the development of substitutes and the operation of the Montreal Protocol.

One flaw in this perspective: after a period of remission, the ozone hole seems to be back at its largest previous size: 29.5 million square kilometers in diameter, around the south pole. This was reported in a statement issued last Friday by the UN weather agency. All told, we still have about 39.8 million tons less stratospheric ozone than before Thomas Midgley invented chlorofluorocarbons (CFCs).

The point is not that the Montreal Protocol has failed (Kofi Annan called the latter “perhaps the single most successful international agreement to date”), but that the ozone layer has not yet recovered sufficiently to be able to deal with other adverse effects – such as an unusually cold and wet stratospheric winter. The general point is simply that, even when technical substitutes and international legal instruments are created, environmental issues can rarely be shelved on a permanent basis.

More on this from the International Herald Tribune.

The second political delegation

After a whole summer without Claire’s sterling conversation, I was glad to see her for a few hours. While energetically complaining about the grading of my research design essay, I had a thesis relevant idea. Perhaps, it could even be a way to introduce the topic. The idea is that science based policy making is a kind of second political delegation.

The founding myth of democracy tells of a participant democracy where citizens (with lots of wisdom and plenty of time on their hands), sit around and decide how the state should operate. Since citizens aren’t all slaveholders anymore, and have other things to do with their time, the myth goes that we delegated political authority to elected representatives. Now, the myth may be faulty and lacking in historical truth, but it is the essence of the argument for the legitimacy of democratic governments – at least, for those who believe in a hypothetical notion of consent, rather than using utilitarian justification.

All kinds of governments delegate areas of responsibility to experts, but the process is most interesting from a democratic perspective. Ancient examples are warfare and diplomacy. Each is critically concerned with information: both about tactics and about the world. Each is not particularly subject to outside scrutiny, both for reasons of secrecy and because expertise in the discipline is required to even understand it. More recently, there has been expert delegation in the economic realm; most notably, central banks have been made independent. Again, information control is important. Again, scrutiny comes from within structures developed and operated by the experts themselves.

When we come to science based environmental policy making, however, things get even more complex. Scientists are often envisioned as being like bridge designing engineers. Policy makers say: we want a bridge here, figure out how to build it and what it will cost. What happens in environmental policy, however, is a far broader delegation: a charge to identify which problems are important, how they work, what their severity will be, how they could be stopped or managed, and how they will interact with each other. Mixed into those calculations are all manner of issues that are not fundamentally technical, but rather ethical, political, or economic.

If the first delegation is defended on the one hand hand in terms of expediency and on the other hand in terms of electoral oversight, what is the equivalent for science based policy? Policy makers of all stripes have two claims to their power: a legitimacy derived from popular consent, and an expertise in governing. Without the first, and without a real ability to scrutinize the second (look at disagreements among economists about whether monetary policy under Alan Greenspan was well managed or not), what is left of the democratic basis of government?

Fish paper edited 62 times

It may be 10:44am. And I may still be awake from last night. But the fish paper is short enough for publication. 4999 words, compared to the original 6800.

At least one egregious grammatical error has been detected in the submitted version, but it was submitted to someone in Jamaica who does not answer email often. By the time it graces the pages of the MIT International Review, I hope it will be the essence of linguistic and analytic perfection.

[Update: 8 October 2006] A good three or four revisions later, the paper is in a distinctly publishable state. I continue to wait upon word of when it actually will be printed.

An Inconvenient Truth

All told, Al Gore’s film An Inconvenient Truth was quite impressive. The combination of factual information and moral or political argumentation was generally well done, though some of the personal asides about Gore’s life were somewhat tangential to the point being made. This is a film I would recommend to almost anyone: regardless of your level of knowledge or existing stance on climate change. It certainly helped to change my thinking on some of the issues.

Gore’s basic argument is really the only sane position on climate change right now: We know for sure that it is taking place. We know that human beings are causing it. Finally, we are not at all certain what the consequences will be, or even their magnitude, but there is reason to be concerned, on the basis both of evidence in the world as it is now and on the basis of reasonable projections. His massive chart showing world temperatures and CO2 concentrations over the past 650,000 years is an especially convincing element of the film. While natural cycles are certainly evident, we are already outside all previous ranges for CO2 and will go far, far beyond in the next fifty years if nothing is changed.

I am increasingly convinced that the potential consequences of global warming justify efforts to stabilize greenhouse gas levels in the atmosphere, ideally at a point lower than their present concentration. While doing so will certainly have costs, it is also likely to have considerable benefits. Products of greater energy efficiency and alternative energy sources could include reduced dependence on places like Venezuela, Russia, and Saudi Arabia. Likewise, improved urban design has the prospect of making our cities rather better places to live, undoing some of the enormous harm done to human population centres by the ready availability of automobiles.

By the end of the film, I had the unusual feeling that it just might be possible to do something effective about climate change in the decades immediately ahead. The barriers are arguably mostly in the form of entrenched interests, as is so often the case when big changes in policy are needed. Hopefully, at the very least, the Canadian government can be pressured into living up to the modest promises we made in Kyoto.

[Update: 3 October 2006] While I am unlikely to trek all the way to London for a lecture, those already there might find parts of this series interesting. My thanks to Ben for passing the information along.

The Economist on climate change

Catching up on the reading that accumulated in my absence, I have just gone through the Survey on Climate Change in the September 9-15 issue of The Economist. Their basic argument is that the possibility of catastrophic harm is sufficient to justify the costs of stabilizing the level of carbon in the atmosphere around 550 parts per million, compared with 280 ppm before the industrial revolution, 380 ppm now, and an estimated 800 ppm by 2100 is current policy goes unchanged. The most plausible dangers identified are disastrous shifts in ocean currents, dramatically cooling Europe, and the prospect of rising sea levels. Even modest amounts of the second could do enormous harm both in the coastal cities of the developed world and the lowlands of places like Bangladesh. Other problems include the possibility of an increase in the frequency and severity of extreme weather events, and large scale species migration or extinction.

Canada is singled out several times as unlikely to meet its Kyoto targets. We are committed to reduce emissions to 6% below 1990 levels by 2012, but seem likely to be 23% above. The survey quotes Environment Minister Rona Ambrose as saying: “it is impossible, impossible for Canada to reach its Kyoto targets.” The Economist had not previously been a supporter of Kyoto, though they surely support countries living up to commitments they have made. With this survey, the magazine seems to have changed tack from general opposition to the Kyoto Protocol to recognition that it may be a valid stepping stone towards a better organized and more all-encompassing climate change policy.

At the very least, the editorial change of heart signals strongly that climate change is no longer an issue whose reality is disputed, not suited to serious consideration by scientists, policy-makers, and the media. With my thesis in mind, it is largely the first group that I paid most attention to while reading this. At several points, the article asserts that it is at the 550ppm level that scientists in aggregate start to become seriously concerned about adverse and irreversible problems associated with climate change. That said, the survey also highlights a number of scientific disagreements and failed predictions. The interplay between science and politics is basically portrayed as a simple relationship between two internally complex dialogs. That is a model I certainly mean to unpack further in my thesis work.

As I didn’t actually manage to go see An Inconvenient Truth at the Phoenix yesterday, I am making another foray tonight for the 7:00pm show.

Britannia Mine copper leaching

A few years ago, I wrote a paper for an essay contest being run by the Fraser Institute, a notoriously right wing think tank in Vancouver. The assignment was to write about a free market solution to an environmental problem, and I suggested that a firm could extract and sell the 450kg of copper leaching out from the Britannia Mine into Howe Sound every day. Because of heavy metal pollution from that source, there is a large marine dead zone just offshore, along the road between the two venues where the 2010 Olympics will be held.

Today, while sitting in my dentist’s waiting room, I read in Time that a company called EPCOR has taken on the project I suggested. I didn’t win the contest, some paper about tradable carbon emissions did, but it’s nice to see that the idea was viable enough to implement in some form. It may be more about public relations than profit – especially since the company is advertising its benevolence – but I am glad to hear that one of the many scourges afflicting that particular marine ecosystem is to be somewhat abated.

North Vancouver hydrology

In the last few days, I have twice been up to the Capilano Reservoir. Located behind Cleveland Dam, it provides much of the drinking water for this part of the city, though it does not generate electricity. I don’t think I have ever seen it at low as it is now. At the top of the dam is a kind of huge rolling blockade that can be raised or lowered to adjust the water level in the dam across a particular range. At present, it is all the way down and there is no water flowing over it. Likewise, there is a larger section of the lake bed exposed than I have ever seen before.

Since the reservoir is normally fed by snowmelt and glacial runoff, every time there is a warm winter we start having water problems. It is even worse when what little snowpack there is is melted early in the summer by high temperatures. Since the dam is unable to hold more than a set amount, it can be necessary to vent a great deal of that excess flow – flow that would be much appreciated a few months later.

As far as I know, there are no rigorous water use restrictions in place, so the hydro engineers must be confident that this supply will see us out until Vancouver’s most rainy winter season begins. For the sake of water supplies next summer – and friends moving to Whistler to ski – I hope that most of that precipitation comes in a solid form, both above a certain altitude and in the area to the north of the city.
