You can only consume so much, but you can hedge against risk to an unlimited degree, and the ultra-wealthy do, suggests Interfluidity, and this makes a mess of a consumption-based economy when you get too much wealth concentrated in a few actors. It’s an interesting argument, but it does kind of hinge on a zero-sum game setting — insurance against risk going only to the highest of bidders (lifeboats on a libertarian Titanic). WWII as a giant re-set button, leading to a temporary age of prosperity. What’s the next re-set? Climate change seems like a good candidate…
Timelapse Arctic Icebound Eyes
The human timescale isn’t appropriate for climate change. We can’t see it minute to minute. Day to day. Year to year. Like watching an analog clock, you never see the hands move, and yet time passes. We need more time lapse eyes.
The National Snow and Ice Data Center (NSIDC) in Boulder automatically generates this plot of arctic sea ice extent (and many others) every day:
It’s probably not horrifying unless you’re a geoscientist.
Paris to return Seine to the people
After 45 years of motorway lining the Seine, Paris is starting to re-pedestrianize the riverside. They’ve been doing it for short periods during the summers with the Paris Plages, but now the plan is to make it permanent. It’s an irresistible destination (all the more so without the motorway), being made inconvenient for or inaccessible to cars. This is, I think, a winning strategy.
Sustainable Energy Without the Hot Air by David MacKay
What does a world without fossil fuels look like? There are lots of different options, but none of them look much like the rich developed nations of the world today. David MacKay’s approach in Sustainable Energy Without the Hot Air is to hold our rate of energy consumption constant, and explore the kinds of carbon-free energy systems that could satisfy that demand. The uncomfortable conclusion he comes to is that if we want to run our world on renewables, the energy farms have to be comparable in scale to nations. Comparable in scale to our agricultural systems. This is because all renewable energy is very diffuse, and we use a whole lot of energy.
Just as an example, of all the renewable power sources solar is the most concentrated, and PV farms like the ones cropping up in Bavaria because of Germany’s generous feed-in tariff average about 5W/m2. With better siting (the Sahara, Arizona) you can do a bit better, and there’s a little more efficiency to be eked out of the panels, but for large scale deployments, you’re not going to get above 10W/m2. If you’re an average citizen of the EU or Japan, your 5kW of power thus demands 500m2 of land. Multiply that by 700 million people in the EU, and you get the total area of Germany. An average North American’s 10kW requires 1000m2. Multiply that by 300 million people, and you get an the entire area of Arizona.

How far will we walk?
How far will we walk to go somewhere depends on the quality of the walking experience. An obvious conclusion maybe, but one that bears repeating. In central Paris or Rome, folks will regularly walk 5 miles a day, and enjoy it, because the cities are lively and interesting the whole way. I have an elderly friend in San Francisco who regularly walks all the way from the Presidio, where she lives, to downtown (and sometimes back again) for errands, but also for the people watching and joy of it. Density alone is not enough to make a place walkable, and lower density — if it’s interesting enough — can still entice people to wear their comfortable shoes. Good details in the original post.
Arizona Public Service Diversifies Generation Sources | Renewable Energy Project Finance
Arizona has decided to include externalized costs like water use and pollution in their utility resource planning process, with the predictable result that they’ve selected a resource portfolio heavy on renewables and energy efficiency, and light on coal. Hopefully other states will follow their lead!
Why climate change is a wicked moral problem
Dave Roberts at Grist picked over a recent Nature paper examining the fact that climate change doesn’t spark moral outrage, the same way terrorist attacks or even oil spills do. and the ways we might try and work around those cognitive issues if we’re going to get sustained political support for dealing with it seriously (original paper here).
In a related vein William Gibson recently commented:
I assume that we live in the first era in human history against which all posterity will have reason to hold a sad and bitter grudge.
Many people responded with things to the effect of “What about slavery?”, referring to past egregious social and economic injustices we’ve inflicted upon each other. I thought his response was poetic:
The difference between knowing murders were committed in your ancestral home and knowing fools let it burn to the ground. Hence your tent.
Thankfully that Nature paper also included potential cognitive and messaging work arounds, so we can hopefully get people to react, and then respond appropriately. Now if only we can bring ourselves to use them.
Like Water for Electricity
Union of Concerned Scientists gives an overview of how water is used in the generation of electricity. I came across this Op-Ed at the NYT that claimed more water is used for electricity than agriculture, and just could not believe it, but apparently if you look at surface water withdrawals, it’s true (power: 41%, ag: 37%). “Withdrawal” just means the water is taken from the river/lake/whatever. Usually most of it is put back (hotter), which means it can be used again for agriculture. In any case, the Texas grid came very close to shutting down 10% of its generation in 2011 because of the drought, right as it was experiencing its highest ever loads. Yet another fun climate-energy feedback.
A Little White Lie-Bor
Turns out the world’s megabanks have engaged in a rate-fixing fraud for years. The London InterBank Offered Rate (LIBOR) is an interest rate index that literally hundreds of trillions of dollars in financial instruments are pegged to. And how is it set? Well, someone phones up 18 duuudes around London every day and says “Yo, if you were gonna borrow money from some other bank right now, what rate would they charge you?” And they can answer with whatever wild-ass-guess they want. So they lied, in order to make themselves more money. Shocking, I know. Seems like the one thing you can trust banks to do is cheat when given the opportunity.
ITDP Releases BRT Standard
ITDP has released a standard by which to measure the quality of a BRT system (in PDF form). It also does a pretty good job of explaining (as a stand-alone document) what it is that makes BRT different from normal bus service.
