“[W]henever I visit a newsroom these days, I instinctively feel unhealthy, like a 19th-century Lake Poet visiting an especially polluted part of London”

Colby Cosh goes well out of his way to rub salt in the wounds of daily commuters, while basking in the glories of working from home:

When Statistics Canada puts its big brains to work on measuring the time devoted to commuting, and the various ways in which people drag their butts to work, I always read the results with the particular interest-fascination-horror of a permanent non-commuter. I am well into my second decade of working full-time, pretty much exclusively, from home. I’m dragged out of the house very occasionally for assignments and broadcast appearances, but most of what I do for a living happens a few feet from my bed.

None of it, I should specify, actually happens in bed (and relatively little of it involves actual writing). As most people who have to physically travel to a job seem to suspect, working remotely gives you a scary, even nauseating freedom to customize your working arrangements. I suppose most of us professional shut-ins find that we have to establish arbitrary rules and mini-disciplines to prevent our lives from becoming totally unstructured and unhealthy. “Bed is for sleep” is one of mine.

All of my conscious writing and research is done strictly at a desk, whether or not I happen to be wearing pants. With that said, as I get older, I do find sleep to be a more important component of my overall work process. Naps can be magical, and the ability to get around a writing difficulty by means of one is something I would immediately miss if I became a miserable corporate prisoner/drone again.

This kind of consideration deepens the psychic divide between commuters and remote workers: we have trouble understanding one another’s worlds even when we have switched between them. Commuters shudder at the thought of an amorphous life with less social contact and minimal formal barriers between work and non-work. Indeed, I think working at home does make one a little dottier (note: this is not necessarily a practical disadvantage for a newspaper columnist). I suspect it may also discourage groupthink. It definitely cuts down on pointless meetings; and whenever I visit a newsroom these days, I instinctively feel unhealthy, like a 19th-century Lake Poet visiting an especially polluted part of London.

I’ve spent more of my time working from home over the last decade than sitting in the office (and therefore also needing to drag my carcass to and from said office), and I really do understand his viewpoint. It’s one of the things I anticipate with no joy at all, as any new job I’m likely to land will probably require a daily commute. On a good day, it’s about an hour’s drive to downtown Toronto, but there aren’t enough good travel days and taking public transit literally doubles that time. Spending four hours per day to get to work and back feels very wasteful, even when I can get in some reading on the way.

Bitcoin

Charles Stross explains why he’s not a fan of Bitcoin (and I do agree with him that the hard limit to the total number of Bitcoins sounded like a bad idea to me the first time I ever heard of them):

So: me and bitcoin, you already knew I disliked it, right?

(Let’s discriminate between Blockchain and Bitcoin for a moment. Blockchain: a cryptographically secured distributed database, useful for numerous purposes. Bitcoin: a particularly pernicious cryptocurrency implemented using blockchain.) What makes Bitcoin (hereafter BTC) pernicious in the first instance is the mining process, in combination with the hard upper limit on the number of BTC: it becomes increasingly computationally expensive over time. Per this article, Bitcoin mining is now consuming 30.23 TWh of electricity per year, or rather more electricity than Ireland; it’s outrageously more energy-intensive than the Visa or Mastercard networks, all in the name of delivering a decentralized currency rather than one with individual choke-points. (Here’s a semi-log plot of relative mining difficulty over time.)

Credit card and banking settlement is vulnerable to government pressure, so it’s no surprise that BTC is a libertarian shibboleth. (Per a demographic survey of BTC users compiled by a UCL researcher and no longer on the web, the typical BTC user in 2013 was a 32 year old male libertarian.)

Times change, and so, I think, do the people behind the ongoing BTC commodity bubble. (Which is still inflating because around 30% of BTC remain to be mined, so conditions of artificial scarcity and a commodity bubble coincide). Last night I tweeted an intemperate opinion—that’s about all twitter is good for, plus the odd bon mot and cat jpeg—that we need to ban Bitcoin because it’s fucking our carbon emissions. It’s up to 0.12% of global energy consumption and rising rapidly: the implication is that it has the potential to outstrip more useful and productive computational uses of energy (like, oh, kitten jpegs) and to rival other major power-hogging industries without providing anything we actually need. And boy did I get some interesting random replies!

QotD: Nuclear winter

In 1975, the National Academy of Sciences reported on “Long-Term Worldwide Effects of Multiple Nuclear Weapons Detonations” but the report estimated the effect of dust from nuclear blasts to be relatively minor. In 1979, the Office of Technology Assessment issued a report on “The Effects of Nuclear War” and stated that nuclear war could perhaps produce irreversible adverse consequences on the environment. However, because the scientific processes involved were poorly understood, the report stated it was not possible to estimate the probable magnitude of such damage.

Three years later, in 1982, the Swedish Academy of Sciences commissioned a report entitled “The Atmosphere after a Nuclear War: Twilight at Noon,” which attempted to quantify the effect of smoke from burning forests and cities. The authors speculated that there would be so much smoke that a large cloud over the northern hemisphere would reduce incoming sunlight below the level required for photosynthesis, and that this would last for weeks or even longer.

The following year, five scientists including Richard Turco and Carl Sagan published a paper in Science called “Nuclear Winter: Global Consequences of Multiple Nuclear Explosions.” This was the so-called TTAPS report, which attempted to quantify more rigorously the atmospheric effects, with the added credibility to be gained from an actual computer model of climate. At the heart of the TTAPS undertaking was another equation, never specifically expressed, but one that could be paraphrased as follows:

Ds = Wn Ws Wh Tf Tb Pt Pr Pe etc

(The amount of tropospheric dust = # warheads × size warheads × warhead detonation height × flammability of targets × Target burn duration × Particles entering the Troposphere × Particle reflectivity × Particle endurance, and so on.)

The similarity to the Drake equation is striking. As with the Drake equation, none of the variables can be determined. None at all. The TTAPS study addressed this problem in part by mapping out different wartime scenarios and assigning numbers to some of the variables, but even so, the remaining variables were — and are — simply unknowable. Nobody knows how much smoke will be generated when cities burn, creating particles of what kind, and for how long. No one knows the effect of local weather conditions on the amount of particles that will be injected into the troposphere. No one knows how long the particles will remain in the troposphere. And so on.

And remember, this is only four years after the OTA study concluded that the underlying scientific processes were so poorly known that no estimates could be reliably made. Nevertheless, the TTAPS study not only made those estimates, but concluded they were catastrophic.

According to Sagan and his coworkers, even a limited 5,000 megaton nuclear exchange would cause a global temperature drop of more than 35 degrees Centigrade, and this change would last for three months. The greatest volcanic eruptions that we know of changed world temperatures somewhere between 0.5 and 2 degrees Centigrade. Ice ages changed global temperatures by 10 degrees. Here we have an estimated change three times greater than any ice age. One might expect it to be the subject of some dispute.

But Sagan and his coworkers were prepared, for nuclear winter was from the outset the subject of a well-orchestrated media campaign. The first announcement of nuclear winter appeared in an article by Sagan in the Sunday supplement, Parade. The very next day, a highly-publicized, high-profile conference on the long-term consequences of nuclear war was held in Washington, chaired by Carl Sagan and Paul Ehrlich, the most famous and media-savvy scientists of their generation. Sagan appeared on the Johnny Carson show 40 times. Ehrlich was on 25 times. Following the conference, there were press conferences, meetings with congressmen, and so on. The formal papers in Science came months later.

This is not the way science is done, it is the way products are sold.
