Today, I was proud to contribute a guest post to the excellent Greenfyre’s environmental blog: The deniers are discrediting themselves.
The site features accessible information on climate science, as well as the differences between genuine skepticism and climate change denial.
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.
It’s nice to see the initiators of a frivolous or abusive lawsuit get their comeuppance. In this case, I am referring to the failed attempt by MagicJack to silence criticism through a strategic lawsuit against public participation (SLAPP) against BoingBoing and blogger Rob Beschizza. Too often, faced by the high costs of going to court and the danger of losing, people who had been legitimately expressing an honestly held opinion (often one protected by constitutional law) are bullied into withdrawing their statement, or even paying a settlement. This is a particular danger in states that have terrible libel laws, like the United Kingdom. It is sad but understandable when firms take the safe course – such as when SuicideGirls when through their bout of unprovoked self-censorship. When someone has the guts to fight back, they deserve public recognition and support.
As such, kudos to BoingBoing and Mr. Beschizza. The $50,000 in legal costs they recovered aren’t enough for them to break even, but their example may have public value in deterring some future SLAPPs. There are strong positive externalities that result when organizations like BoingBoing take the courageous course and succeed. Such outcomes help to remind others that free expression is a vital aspect of free and democratic societies, and that attempts to suppress it through legal threats are inappropriate and anti-democratic. They also make it clear to potential filers of SLAPPs that they may end up with even more public embarrassment at the end of the process than they started out with.
For practicality, you can’t beat the Celsius temperature scale. Were it not for the stubbornness of Americans, the weird Fahrenheit alternative (initially established with ice, brine, and an armpit) would be long-gone. For scientists, the Kelvin scale lets you represent temperature appropriately for thermodynamic calculations, and helpfully retains the same unit size as Celsius.
I would have thought the case would be closed there, but Bill Streever’s book made me aware of a more romantic-sounding alternative: degrees of frost. This temperature measure – a favourite of penguin-egg-gatherer and Antarctic explorer Apsley Cherry-Garrard – measures how many degrees it is below the freezing temperature of water.
Naturally, I prefer the Celsius version, though it sounds a bit less dramatic. Right now, it is a completely tolerable -4˚C in Ottawa. That’s just four degrees of frost – nothing to compared to the 60.8 degrees of frost experienced by Cherry-Garrard. The worst I’ve seen in Ottawa is about thirty degrees of frost, during my first frozen winter in Ottawa. Wind chill, incidentally, is not really a very scientific thing.
In brief, I am starting a new group blog at BuryCoal.com. It exists primarily to make the case for leaving coal and unconventional fuels underground, where they cannot harm the climate.
The reading I have done in the last year has highlighted a few important perspectives for me, when it comes to climate change. The most important thing is humanity’s total cumulative emissions. As such, it is not enough just to use fossil fuels more efficiently. We need to stop using them long before they run out: particularly, before the world’s massive reserves of coal and unconventional fossil fuels are tapped. The warming that would arise from burning all the coal, oil sands, shale oil, and methane clathrates would be far greater than that caused by burning conventional oil and gas.
Government plans that include serious restrictions on the use of coal and unconventional fossil fuels have a chance at being compatible with avoiding dangerous climate change, while those that treat this as a side issue do not.
In order to spread the word about the importance of leaving coal and unconventional fossil fuels in the ground, I have launched a new website at BuryCoal.com. It will be accepting submissions on all matters relating to coal and unconventional fossil fuels, including extraction, air and water pollution, climate change impacts, politics and activism, and more. I don’t think there is any other site out there with its main focus on the message that these fuels must be left in the ground, for the sake of improving our chances of experiencing catastrophic or runaway climate change, and on account of the other benefits that accompany moving beyond them. Those include reduced pollution and destruction of habitat, as well as reduced dependence on fossil fuels which will inevitably run out anyhow.
I would really appreciate if visitors to this site would do three things to help with the new project:
The kind of world our grandchildren and great grandchildren end up living in will depend a great deal on what proportion of these fuels we dig up and burn. BuryCoal.com has been established to be the antithesis to “Drill, Baby, Drill” and make a forceful and well-reasoned case for leaving all that carbon safely underground, while moving to a zero-carbon, renewable global energy system that can sustain human prosperity and civilization indefinitely.
Writer Robert Pool has defined a ‘witness’ as “someone who believes he has information so important that he cannot keep silent.” In the preface to his book, Storms of My Grandchildren, climatologist James Hansen identifies himself using the term. It is truly worrisome to be living in an age when such a prominent climate scientist sees his role in this way – and sees himself as having uncovered information of such importance that he cannot remain an adviser on the political sidelines. Storms of My Grandchildren is the most frightening thing I have ever read, and may end up being one of the most important.
James Hansen explains why we know as much as we do about the climate: not from computerized climate models, but from the evidence of climatic history laid down in ice cores and sediments. The story they tell is one of a dynamic system capable of amplifying small initial changes, and one in which rapid swings have taken place. Hansen identifies the greatest risks from climate change as the destabilization of ice sheets and the loss of biodiversity accompanying the many effects of climate change. On sea level rise, he explains:
If humanity burns most of the fossil fuels, doubling or tripling the preindustrial carbon dioxide level, Earth will surely head toward the ice-free condition, with sea level 75 meters (250 feet) higher than today. It is difficult to say how long it will take for the melting to be complete, but once ice sheet disintegration gets well under way, it will be impossible to stop. (p. 160 hardcover)
Hansen also highlights how positive feedback effects could lead to a runaway climate change scenario, and how the methane locked up in permafrost and methane clathrates has the potential to stack a second gigantic warming on top of the anthropogenic greenhouse gas warming, in the event they ever substantially melt:
[T]he world, humanity, has reached a fork in the road; we are faced with a choice of potential paths for the future. One path has global fossil fuel emissions declining at a pace, dictated by what the science is telling us, that defuses the amplifying feedbacks and stabilizes climate. The other path is more or less business as usual, in which case amplifying feedbacks are expected to come into play and climate change will begin to spin out of our control. (p. 120 hardcover)
In the most extreme case, in which all coal and unconventional oil and gas are burned, the stacked-up positive feedbacks could be sufficient to boil away the oceans, eventually leaving Earth in a state similar to that now inhabited by Venus, a planet formerly adorned with liquid water before a brightening sun induced runaway climate change there.
In addition to the scientific story, Hansen tells some of his own: about the censorship he witnessed at NASA, about his recent civil disobedience actions against mountaintop removal coal mining, about is perceptions of American politics, and about the grandchildren whose prospects have left him so concerned. Sometimes, these asides can seem secondary to the main thrust of the book, though they do underscore the extent to which this is an impassioned personal plea, not a technical scientific assessment. The insight into the scientific process and the operation of the Intergovernmental Panel on Climate Change (IPCC) are also interesting.
The most dubious part of the book may be Hansen’s optimism for fourth-generation fast breeder reactors. He highlights their possible advantages, namely in terms of stretching our uranium fuel supplies, but doesn’t give serious consideration to the practical and economic issues with a massive nuclear deployment. He is also overly pessimistic about renewable forms of energy. I would recommend that he take a look at David Mackay’s excellent book on different routes to a zero-carbon energy future. People who read Hansen’s book may also be well-advised to do so.
Hansen makes some key points about climate policy: notably, that emissions targets and cap-and-trade schemes are meaningless, if governments continue to allow coal use and the exploitation of unconventional oil and gas to continue. Those are the fuels that contain enough carbon to threaten all life on Earth; meaningful climate policy must, among other things, ensure that they remain underground. As an alternative to cap-and-trade schemes that are potentially open to manipulation and which offer no incentive to cut faster than prescribed by the cap, Hansen endorses a fee and dividend system where a tax is applied to all fossil fuels at the point of production or import. His overall view is not so different from the fantasy climate change policy I wrote earlier, though I hadn’t been fully aware of all the risks Hansen enumerates when I wrote it.
In the end, Hansen has provided as clear and compelling a warning as anybody could ask for. We are putting the planet in peril and endangering the lives and prospects of future generations in a deeply immoral way. Governments are misleading people with the sense that they are handling the problem when, in reality, even states taking climate change seriously are doing nowhere near enough to ensure that catastrophic or runaway climate change goes not occur. We need to change the energy basis of our society, and keep the carbon in coal and unconventional fossil fuels in the ground. In so doing, we may be able to stop the warming we are inducing, before it generates the devastating feedbacks that are the key message of Hansen’s book.
Those interested in reading this book should consider taking me up on my offer for a free copy. For those unwilling to commit the time to go through a 275-page book, Hansen has a more concise presentation online in PDF form.
Partly prompted by this book, I am in the middle of starting up a new personal project, intended to help with the planet-wide coal phaseout that is necessary. I will make more information on it public, once it is developed further.
[16 February 2010] Now that I have a fuller understanding of the importance of not burning coal and unconventional fossil fuels, because of their cumulative climatic impact, I have launched a group blog on the topic: BuryCoal.com. Please consider having a look or contributing.
Having personally populated a small library full of books on climate change, I can say with some authority that James Hansen’s book Storms Of My Grandchildren
As such, and in the interests of improving debate here, I am willing to make the following offer:
Basically, if you are an active member of this community and you will read the book, I will send you a copy.
More specifically:
People who can afford to are encouraged to buy the book themselves, rather than take advantage of this offer. Hardcover copies are on Amazon for $19.44 Canadian.
[Update: 5 February 2010] My review of Hansen’s book is online.
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.
In their attempt to express how important philosophical ideas relate to jokes, Thomas Cathcart and Daniel Klein are largely successful. Indeed, their hypothesis that there is a relationship between the philosophical and the joking mentality ends up seeming like a plausible one, as jokes are used to illustrate issues in metaphysics, logic, epistemology, ethics, the philosophy of religion, existentialism, the philosophy of language, social and political philosophy, relativity, and meta-philosophy.
Some of the jokes in Plato and a Platypus Walk into a Bar: Understanding Philosophy Through Jokes do feel a touch dated – with a strong emphasis on somewhat off-colour jokes based around traditional attitudes towards sexuality. Still, the book is a fun, quick read and worth a look if you are looking for some light-hearted yet academic contemplation.
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.
