Global warming and our urban future

ghg-tables1Worldchanging reports on yet more evidence of urban living being less carbon-intensive than suburban living:

The authors of this study, published in The Journal of Urban Planning and Development, quantified the emissions from building materials and construction, home heating and power demands, and transportation energy, in both urban suburban neighborhoods in the Toronto metro area. And they found that downtown residents use radically less energy, and consequently emit about two-thirds less climate-warming CO2 than their suburban counterparts.

I had been vaguely aware that the suburban lifestyle produced more greenhouse gases, but the extent is surprising.

Upsides to the downturn – work less, die later

Chinese card playersPeriods of economic recession are bound to affect your health negatively, right? Well, not according to Christopher Ruhm, economics professor, whose research suggests that health actually improves in recessions:

In studies over the past 10 years, Ruhm has consistently found death rates decline during recessions and rise when the economy expands. If unemployment rises 1 percent, he estimates the death rate will fall by about half a percent.

“I tracked things like unemployment and mortality and found that they were almost a mirror image of each other,” Ruhm said.

Other researchers have found evidence of improved health during economic downturns in Cuba, Germany, Japan and Spain. Think of it as a silver lining — and perhaps a measure of how much our unhealthy lifestyles and workaholic tendencies can get the best of us during boom times.

[…]

Some experts remain skeptical, in part because of overwhelming evidence that people who lose jobs suffer poor health because of it. Depression, anxiety, drug and alcohol abuse, and anti-social behavior become significantly more likely after a person gets laid off.

As with so many articles of this type, there’s actually no conclusive proof either way. The causality of changes in the death rates is going to be affected by a multitude of interdependent factors, of which the state of the economy is just one (albeit a fairly significant and influential one).

That said, there’s a nugget of appealing logic at the core of Ruhm’s research. How much does the amount we work (and what we get paid for that work) really compensate us for the loss of what might be a somewhat spartan but more leisurely lifestyle? If the link was found to be explicit, what trappings of your current life would you be willing to sacrifice in exchange for a happier, healthier life? Or is this just another rehashing of Walden Pond for the modern age, a desperate grab for a silver lining in a cloudy sky?

Singularity school with Vernor Vinge

Puzzled by posthumanism? Looking for an entry-level introduction to this thing that people call the Singularity? Well, sometimes it’s best to go straight to the source – sf novelist and computer scientist Vernor Vinge coined the concept of the Technological Singularity in 1993, so who better to explain the basics, as in this brisk interview at H+ Magazine:

Some folks will say there have been singularities before — for instance, the printing press. but before Gutenberg, you could have explained to somebody what a printing press would be and you could have explained the consequences. Even though those consequences might not have been believed, the listener would have understood what you were saying. But you could not explain a printing press to a goldfish or a flat worm. And having the post-Singularity explained to us now is qualitatively different from explaining past breakthroughs in the same way. So all these extreme events like the invention of fire, the invention of the printing press, and the evolution of cities and agriculture are not the right analogy. The technological Singularity is more akin to the rise of humankind within the animal kingdom, or perhaps to the rise of multi-cellular life.

It’s tricky trying to explain something which, by definition, is inexplicable – which is probably why the Technological Singularity is as hard to pitch at the average layman as at an industry expert. I’m still not sure I “believe” in it as anything more than a convenient metaphor for a world that changes fast enough to alienate people within their natural lifespans, but on that level alone it’s hard for me to think about the passing of the next thirty years – which would see my lifespan little less than doubled – without realising I’m going to feel like a stranger in a strange land on an hourly basis. Hell, it already happens at least once a day.

So, what do you lot make of the Singularity – inevitable geek rapture? Metaphor for an accelerating culture? Or just the sound of comp-sci lips flapping in the breeze at sf conventions?

Mobile Massively Multiplayer – Warcraft on the iPhoe

Here’s some big news for the gamers among you (provided it’s not an elaborate and well-produced hoax) – a World of Warcraft client that runs on the iPhone.

Found via The Guardian, where Greg Howson asks whether the cramped screen real-estate and network lag would make it worth bothering. I figure that’s an academic question, really; I imagine if I (a) played WoW and (b) had an iPhone, I’d be mad keen for a mobile version; I mean, who wouldn’t be, right? If you’re an iPhone and MMO geek, you’re going to go mad for the idea of getting the best of both at once…

But more to the point (and the main reason I called it out), it’s another SF Prophecy Point on the leaderboard for Charlie Stross, who included mobile MMO gaming as a core trope in his 2007 novel Halting State. Two years from science fiction to reality – things move fast, don’t they?

The Red Dragon has no head – China’s citizen hackers

Chinese flagsThere’s been plenty of press recently about the threat of Chinese hackers undermining infrastructure in the West, and about the GhostNet network, which may or may not be a covert espionage tool of China’s government.

The trouble is that the line between state-sponsored or military hackers and young patriots with time and talent isn’t clear; it may be that the bulk of the “red hackers” aren’t employed by their government, and are just hobbyists with a convenient target. Some folk do it “for the lulz”; these people are allegedly doing it for their nation. [image by parrhesiastes]

From China, where I’ve lived for four years, this assessment looks spot-on. Hackers are pervasive, their imprint inescapable. There are hacker magazines, hacker clubs and hacker online serials. A 2005 Shanghai Academy of Social Sciences survey equates hackers and rock stars, with nearly 43 percent of elementary-school students saying they “adore” China’s hackers. One third say they want to be one. This culture thrives on a viral, Internet-driven nationalism. The post-Tiananmen generation has known little hardship, so rather than pushing for democracy, many young people define themselves in opposition to the West. China’s Internet patriots, who call themselves “red hackers,” may not be acting on direct behalf of their government, but the effect is much the same.

Is this, perhaps, the new emergent youth politics? Going out and fighting for what you believe in out in the digital trenches – even if the thing you’re fighting for isn’t quite what you think it is. And hey – if you get powerful enough, maybe it’ll start changing to be more like what you want to keep you sweet, as it becomes increasingly dependent on your leverage beyond the border. Talk about grass-roots change, right? [via Bruce Sterling]

What’s interesting to me is that patriotism can motivate these kids to hacking. Here in the UK, the most that nationalist sentiment can seem to stir up in young folk is the desire to thump brown people, and those easily swayed by such desires aren’t often in the possession of a mentality that would lend itself to 00b3r-1337 computer skillzorz; as a general rule, Western hackers tend to work against governments and authority (how much is that due to the influence of cyberpunk literature?), so it’s a cognitive dissonance moment for me to read about kids voluntarily furthering the cause of their nation rather than their own interests.

Which is one of the things that makes me wonder just how true all of these stories are. As a general trend, the last twelve months have seen a big increase in news stories that give us reason to fear an amorphous and distant conceptual bundle labelled “China”, in inverse proportion to coverage of the previous faceless multiplex global enemy, namely Muslim extremism. The economic crisis has made this particularly easy (China is buying up western debt! China is stockpiling commodities!), and climate change is a nice lever too (China won’t stop polluting, so why should we?).

While I understand the need for political rhetoric (and the media that feed from it, remora-like) to set up ideological opponents against which to rally the diminishing regiments of Western patriots, I sincerely hope we’re not headed for some sort of Cold War re-run. We’ve enough problems on our plate as it is.
