Conference on a world more than four degrees warmer

Given our increasingly slim chances of avoiding more than 2˚C of global warming, it makes sense to start thinking about what a world hotter than that could be like.

The University of Oxford recently hosted a conference on the subject: 4degrees International Climate Change Conference: Implications of a Global Climate Change of 4 plus Degrees for People, Ecosystems, and Earth Systems.

32 of the short lectures are available free, via iTunes.

As an aside, posts might be thin here for the next while. Work is busy, and I am concentrating efforts on BuryCoal. If you haven’t had a look at that site yet, please do. Some good discussions on the posts people have already written would be just the thing.

After the Ice

Having already read a great deal about climate change and the Arctic, I expected Alun Anderson’s After the Ice: Life, Death, and Geopolitics in the New Arctic to provide only a moderate quantity of new information. I was quite surprised by just how much novel, relevant, and important content he was able to fit into the 263 pages. The book discusses the historical and current relations between governments and Arctic indigenous peoples; ice flow dynamics and exploration; the changing nature of Arctic ecosystems and species, along with information on what climate change may do to them; international law and the geopolitical implications of a melting Arctic; oil, gas, and other natural resources, and how their availability is likely and unlikely to change in coming decades; the rising tide of Arctic shipping, and the special safety and environmental considerations that accompany it; and the feedback effects that exist between a changing Arctic and a changing climate.

Ecosystems

Some of the best information on the book is about biology and Arctic ecosystems. It describes them from the level of microscopic photosynthetic organisms up to the level of the megafauna that gets so much attention. Anderson argues that most of the large marine mammals (seals, walruses, whales, etc) are threatened to some extent or another by the loss of sea ice. This is for several reasons. First, it could disrupt the lowest levels of the food web they rely upon. Second, it could permit the influx of invasive species that could out-compete, starve, or attack existing Arctic species. Third, the lifecycles of Arctic animals are slow and deliberate, and thus liable to disruption from faster-breeding competitors. Disappearing sea ice off Svalbard has already completely wiped out what was once “one of the best areas for ringed seal reproduction.” Arctic species, argues Anderson, will need to “move, adapt, or die.” Generalists like beluga whales have promise, while the narwhal and polar bear may be the most vulnerable large creature in the ecosystem.

One consequence of the loss of multi-year sea ice that I had not anticipated is the potential for a massive migration of species between the Pacific and Atlantic oceans, with invasive species potentially seriously altering the composition of ecosystems on both sides. Melting ice could therefore produce major changes in much of the world’s ocean. Even before that, expanded range for orcas could have a significant effect on life in northern waters. Where ice used to provide safety, by obstructing their pectoral fins, these powerful predators increasingly have free reign.

Resources, shipping, and tourism

Anderson makes an effective argument that most of the oil, gas, and resources in the Arctic will be effectively locked away for some time yet. There will always be ice in the winters, glacial ice calving off Greenland and other Arctic islands poses a significant risk due to its extreme hardness, and very high commodity prices are necessary to justify the risk and capital investment required to operate in the region. (See this post on the the Shtokman gas field.) He expects that, even if there is a boom, it will be short-lived and of limited benefit to those living in the region. In particular, he cautions people living in the north not to abandon traditional ways of life sustained by things other than oil and gas. Living for a couple of rich decades and then being left with nothing would be a tragic outcome.

The book also downplays fears about a scramble for resources and sovereign control. Anderson argues that the United Nations Convention on the Law of the Sea (UNCLOS) already provides a clear legal framework and that negotiated outcomes are probable. That should provide some comfort to those concerned about diplomatic or even armed conflicts in the changing north. One danger Anderson does highlight is how the risk of collision with ice, increasing shipping and tourist traffic, and the absence of emergency response capabilities could combine. He describes plausible scenarios where major oil spills or massive loss of life could result, due to a problem with a tanker or a cruise ship (disproportionately full of elderly people susceptible to cold, as they are).

While Anderson does an excellent job of explaining some of the risks to species and human beings from a changing Arctic, he doesn’t take seriously the possibility of truly radical or catastrophic change, of the kind highlighted as possible by James Hansen. Anderson also completely fails to describe how the incremental emissions from burning oil and gas in the Arctic would inevitably increase the degree of climate change experienced by humans and natural systems. It is cumulative emissions that matter most, and extracting hydrocarbons from the far north can only increase those.

For anyone with an interest in what is happening to the Arctic and what the medium- and long-term implications of that might be, this book is enthusiastically recommended.

Best books of 2009

Back in 2007, I put up a post listing my five favourite books of the year. Somehow, I missed 2008. Despite that, I am still happy to assert that the 2007 list includes some of the best books I have ever read.

Among the books I read in 2009, these are the five I most emphatically recommend:

It was a tough choice.

Margaret Atwood’s The Year of the Flood would be a natural successor to Oryx and Crake back in 2008. Unfortunately, the better book of the two remains the original.

If I had read Jared Diamond’s Collapse: How Societies Choose to Fail or Succeed soon after it had come out, it might have been one of my choices. That said, it is a compelling and important book.

Richard Dawkins’ The Greatest Show on Earth: The Evidence for Evolution certainly deserves a nod. For anyone who wants a comprehensible account of why we know as much about evolution as we do, this is the book to read.

You can read all my book reviews here.

I may eventually cook up a retroactive 2008 list.

Obama’s nuclear loan guarantees

President Obama has announced that the federal government will provide $8 billion in loan guarantees for two new reactors: the first to be built in the United States since 1979. The guarantees mean that, in the event that plant owners cannot ultimately pay their bills, the government will step in with the promised funds.

There are many reasons to be wary of nuclear power as a climate change solution, with cost and deployment times perhaps the most important (climate change is more threatening than waste, accidents, and proliferation). That said, we need to nearly phase out fossil fuel emissions by the middle of the century. Despite the thirty-year gap in construction, nuclear is still the most important zero-carbon source of electricity in the United States.

It remains impossible to know the true cost of nuclear power, once all the explicit and implicit subsidies are taken into account, as well as connections between military and civilian programs. That said, it looks like we need every low-carbon energy option available.

Hacking Chip-and-PIN

Apparently, the authentication system on Chip-and-PIN bank cards is fundamentally flawed. You can manipulate the system to accept any PIN, by taking advantage of the negotiation system used between the merchant and the bank’s authorisation system. This post and this technical paper provide more details on the vulnerability. These cards are common in Europe, and being increasingly rolled out in North America for security reasons. Perhaps the banks doing so should rethink that.

This seems like another example of how serious breaches in electronic security systems are rarely caused by attacks against encryption algorithms directly. Much more often, it is some other component of the system that is weak.

The Invention of Lying

The film Ricky Gervais film The Invention of Lying is based around a fascinating central conceit, but ultimately fails to explore it in an interesting way. The film imagines a world in which people are simply incapable of telling falsehoods, and in which they automatically accept any statement from another person as true. While bits of the film are very funny, it is disappointing that the protagonist who learns how to lie uses it for such uninspired things as cheating at casinos and manipulating the affections of the pretty but dull female lead. Indeed, beyond her appearance there is never any indication of why she is an especially desirable partner. You would think someone with truly awesome powers to manipulate all of humanity might dream up some grander projects than getting rich and rearing children with the woman he happened to meet just before his discovery.

One awkward issue is that people frequently provide bad information for reasons other than deceit. They provide old information, misunderstand things, get bad readings from equipment, and so on. In any functional world, people would need to be able to realize that these sorts of errors occur. Furthermore, this kind of basic scrutiny seems absolutely necessary for the development of science and technology. It is hard to see how people could be capable of parsing out bad information that others provide by accident, while simultaneously being unable to imagine that someone might intentionally tell them something incorrect. As such, Gervais’ world would either be seriously lacking in scientific or technological sophistication or simply be very improbable.

I also think a world without lying would be dramatically different from ours in ways that go beyond dialogue, the procedures at banks, and the kind of films that are made. I doubt that the basic political and social structures in such a world would so closely resemble ours, given the extent to which falsehood and misinformation are fundamental to our political and economic systems, and even our day-to-day interactions. The film never shows much of the world beyond the first world town in which it is set. You have to wonder what the world at large would resemble. For instance, it seems unlikely that dictators could emerge or endure in a world where they needed to be entirely truthful. It is also interesting to imagine what the world of international relations and diplomacy would look like.

The actual invention of lying is what security researchers would call a ‘class break’ – a discovery that renders an entire system vulnerable by creating new sorts of attacks. For instance, while learning the combination to one lock could permit a security breach, realizing that all padlocks of a certain type can be opened with a shim is a class break. Being able to lie to people who would automatically accept anything you claimed as true would be an overwhelming instance of this effect. Indeed, it seems impossible that in a world governed by natural selection, the ability to be deceitful would not spread rapidly, completely eliminating the trusting world that existed before, and which was in an unstable state as soon as lying became possible. You would eventually expect a new equilibrium to arise with key features present in our own world: from mental scrutiny to background checks to legal systems designed to minimize the damage caused by malicious individuals.

In any event, the film prompts some interesting thinking, even if it sticks to a rather conventional romantic comedy structure (complete with the nasty bad guy competing for the trophy woman in question). I suppose the film’s value lies more in the comedy than in really exploring the central concept. Some of the explicitly truthful dialogue is certainly quite amusing, particularly when it occurs in places where we expect white lies, rather than malicious falsehoods, to be told. For instance, the first date between the male and female lead, set in a somewhat fancy restaurant, is perhaps the best part of the film. It is when the most trivial lies are avoided that the most amusement results.

Bright-Sided

From Oprah to New Age philosophy, ‘positive thinking’ has become a hugely influential movement in business circles, the religious sphere, in pop medicine, and elsewhere. In Bright-Sided: How the Relentless Promotion of Positive Thinking Has Undermined America, Barbara Ehrenreich makes the case that the movement is poorly thought out and damaging. Her arguments are convincing, especially when it comes to situations where positive thinking is used to blame the victim when they suffer as the result of developments beyond their control: be it the movement towards corporate downsizing (which corresponded with the rise of motivational speakers in the workplace) or the unjustified assertion that cancer patients are responsible for their own worsening or recovery, on the basis of the mental attitudes they maintain.

Ehrenreich highlights how relentless optimism leads to dangerous groupthink, in which risks are downplayed and those who raise legitimate worries are sidelined. She provides ample evidence that these factors played a role in the inflation of the global house price bubble, and have continued to have important economic and political effects. These include the weird state of deluded isolation in which society’s richest people now reside. She also spends considerable time discussing the warped theology in which god is seen as a sort of mail-order service, happy to send you whatever good things (houses, cars, promotions) you are able to ‘manifest’ for yourself, simply by fervently desiring them.

Positive thinking involves a weird reversal, when it comes to dealing with risks. They cease to be external (concern that your company might fire you to improve their short-term profitability) and become entirely internal (fears about what your state of mind might do to you). It is also tied fundamentally to the notion that happiness is not most important in itself, but rather insofar as it influences events: “Nothing underscores the lingering Calvinism of positive psychology more than this need to put happiness to work – as a means to health and achievement, or what the positive thinkers call ‘success.'” The former tendency puts people in danger of worrying about the wrong things, while the latter strategy puts them at risk of seeking to achieve particular outcomes in nonsensical ways. That is especially dangerous when it comes to making big purchases on credit, firm in your belief that the universe will provide you with the means of dealing with it later.

Ehrenreich’s points are well-taken, though the book can be a bit tedious to read at times. There are also some partial contradictions. It is repeatedly asserted that there is no medical evidence that thinking positively improves health outcomes, yet it is taken as plausible that George Beecher was able to speed his demise through negative thinking. In the course of her analysis on the medical evidence, Ehrenreich claims to be “not in a position to evaluate” evidence that those with a positive outlook may have some protection against heart disease, but is seemingly happy to evaluate research on other illnesses that confirms her hypothesis.

All told, Ehrenreich makes important points about the poisonous institutional culture that accompanies an excessive focus on positivism – and the view that individuals are almost entirely responsible for what happens to them. Her concluding call for ‘realistic’ thinking is certainly appropriate enough, though perhaps she does not go far enough in suggesting how the empire of positive thinking she has mapped the outlines of might be deconstructed. As the world continues to grapple with real problems, magical thinking cannot be a substitute for dispassionate analysis, risk management, and contingency planning. How we get from our world to one more like that, however, remains mysterious.

Overreacting to fears of terrorism

Writing for Salon.com, pilot Patrick Smith makes some excellent points about the breathless paranoia we now display about terrorism:

What has become of us? Are we really in such a confused and panicked state that a person haplessly walking through the wrong door can disrupt air travel nationwide, resulting in mass evacuations and long delays? “The terrorists have won” is one of those waggish catch-alls that normally annoy me, but all too often it seems that way. Our reactionary, self-defeating behavior has put much at stake — our time, our tax dollars and our liberties.

In fact, over the five-year span between 1985 and 1989 we can count at least six high-profile terrorist attacks against commercial planes or airports. In addition to those above were the horrific bombings of Pan Am 103 and UTA 772, the bombing of an Air India 747 over the North Atlantic that killed 329 people, and the saga of TWA Flight 847.

Here in this proclaimed new “age of terrorism,” we act as if the clock began ticking on Sept. 11, 2001. In truth we’ve been dealing with this stuff for decades. Not only in the 1980s, but throughout the ’60s and ’70s as well. Acts of piracy and sabotage are far fewer today.

Imagine the Karachi attack happening tomorrow. Imagine TWA 847 happening tomorrow. Imagine six successful terror attacks against commercial aviation in a five-year span. The airline industry would be paralyzed, the populace frozen in abject fear. It would be a catastrophe of epic proportion — of wall-to-wall coverage and, dare I suggest, the summary surrender of important civil liberties.

What is it about us, as a nation, that has made us so unable to remember, and unable to cope?

The message is similar to that of the excellent essay “Milksop Nation,” which won an Economist essay contest in 2002. Namely, that we do a poor job individually of assessing risks. We obsess over rare risks in which malicious actors want to do us harm, and we downplay common risks that are enormously more likely to injure or kill us. Worse, our political systems amplify our fears to the point of absurdity.

One thing we certainly need are people with the clear-sightedness and bravery to point out that we are fearful about the wrong things, and that we have real, pressing problems that we ought to be concentrating on instead.

Fight censorship, join TOR

Google’s decision to challenge the Chinese government on their censorship policy is a bold one. It remains to be seen whether it will end up doing more harm or good. In the mean time, there is at least one thing that ordinary computer users can do in order to fight censorship around the world: set up a TOR relay. TOR is a project that allows for anonymous internet browsing through a system called onion routing. It is maintained by the Electronic Frontier Foundation.

By setting up a relay, you allow people whose internet access is censored by their governments to access sites that would otherwise be blocked; you also facilitate important democratic processes, such as the actions of whistleblowers. The process of installation is relatively simple, and you can easily cap how much of your bandwidth is given over to the TOR network. By sharing a bit of your bandwidth, you could be helping out human rights activists in China or Myanmar, or just helping some ordinary computer user circumvent annoying restrictions imposed from above. Systems like TOR help the internet to retain some of its vast potential, even in the face of fearful governments that want to control it or shut it down.

One thing to watch out for is that acting as a webserver may be forbidden by your internet service provider (ISP). I checked with mine (TekSavvy), and they have no objections to customers running any kind of webserver, provided they stay within their bandwidth limits.

People interested in this sort of thing may also want to learn about Project Honeypot – a distributed mechanism for fighting spammers.

Pro-photography protest in London

Yesterday’s pro-photography protest in London was rather encouraging. Amateur and professional photographers came together to protest the restrictions and harassment of photographers that has developed in response to concerns about terrorism. The protest follows a European Court of Human Rights ruling that police don’t have the right to indiscriminately search people, just because they are taking photos. The “I’m a photographer, not a terrorist” campaign has objected specifically to police using Section 44 of the UK’s Terrorism Act to harass photographers. High-profile recent incidents include “7 armed police detaining an award winning architectural photographer in the City of London, the arrest of a press photographer covering campaigning santas at City Airport and the stop and search of a BBC photographer at St Paul’s Cathedral and many others.”

In addition to creating art and a historical record, photography has an important role to play in keeping security entities accountable for their actions. As I have said before, photography is an important mechanism for maintaining oversight over the police and private security forces. Restrictions on photograpy allow for power to be used with less oversight, probably leading to more incidents of abuse and fewer cases in which abusers are punished. Indeed, it has been shown repeatedly that only photo or video evidence is sufficient to produce convictions for police brutality. In short, restricting photography makes us less safe.

Both casual photographers and those with a more substantial connection to the practice should be aware of their rights as photographers, and be willing to stand up when people try to bully them out of taking pictures. The British campaign has produced a pocket sized card outlining what rights individuals have when stopped by a police officer. I have been meaning to print off and laminate a card with the relevant sections of Canadian law, for use next time someone insists that taking photos in public spaces is forbidden.
