LA terminates luxury option for electric car owners

Filed under: Environment, Technology, USA — Tags: , , , , , — Nicholas @ 12:43

It’s telling that one of the folks quoted in this article clearly identified the free parking at the airport as a primary reason for buying an electric vehicle:

On a recent morning, Jack Luu parked his plug-in Toyota Prius in one of the most expensive lots at Los Angeles International Airport before flying off to a film shoot in Canada. The lot, where Mr. Luu leaves his car as many as 10 times a month for business trips, normally charges $30 a day.

But when Mr. Luu returned home three weeks later, he drove out, as usual, without paying a dime.

“That was a huge reason why I bought the car in the first place,” says the 35-year-old Santa Monica, Calif., postproduction company executive, whose car qualifies for free parking for up to a month at a time in two of LAX’s most convenient—and costly—short-term lots.

Other than that, he says his ride is “expensive, underpowered and not really all that green,” because it can run just 12 miles on electricity before switching to gas.

For years, LAX has offered electric-vehicle owners one of the most generous incentives of its kind in the country: free parking for 30 days in two of its terminal lots, which contain, altogether, 38 charging stations. The rule was meant to encourage people to buy greener cars, but lately it has turned the lots into a mob scene, with some electric-vehicle drivers circling the stations desperately for electricity or running extension cords while others hog the charging spaces for weeks at a time.

Using the term “Mother Gaia” unironically

Filed under: Environment, Media, Politics, Religion — Tags: , , , — Nicholas @ 13:07

In the Globe and Mail, Gordon Gibson discusses the “Church of Green”:

Religions have certain characteristics. They consist of a body of belief based on faith (as, for example, in God). This faith is not to be challenged, distinguishing religions from other belief sets. Scientific theories, for a counterexample, must always be questioned. Not so with religion. Unwavering faith is the hallmark.

Religions of the sort decried by Mr. Bouchard have high priests who can speak ex cathedra and gain immediate belief. David Suzuki, Al Gore and Amory Lovins, among others, have this otherworldly gravitas. They have their religious orders. Just as there are Jesuits and Benedictines, there are Greenpeace and the Sierra Club.

Religion has an enormous usefulness to many individuals. But there’s more. Religion is, by its nature, absolutist. Because it embodies the Truth, one should not deviate. Of course we all sin, but deliberate tradeoffs are not permissible. It’s not allowed to do a little bit of evil to become a little bit rich, and especially not great evil for great wealth.

Such absolute rules can work fine for individuals. They can do as they wish and take the consequences. It’s where religion is imported to govern the doings of the collective — of a society — that the trouble begins.

[. . .]

Now, no one could argue against the need for great weight to the natural environment. The difficulty comes in agreeing — or not — to tradeoffs. If we take an absolutist position, we humans are rather bad for the planet, so we should all do the decent thing and stop having children.

This was Mr. Bouchard’s point. His issue in Quebec was “fracking” to produce natural gas. The current “religion” in Quebec is that fracking is bad, just as in B.C. pipelines are bad. Among true believers in both cases, absolutism reigns. The badness is self-evident; the projects must not proceed. You can’t trade a little evil for a little wealth — there must be zero chance of harm.

We’re at “peak farmland”

Filed under: Economics, Environment, Food, Health, Technology — Tags: , — Nicholas @ 10:17

Matt Ridley on an interesting paper from Jesse Ausubel and Iddo Wernick of Rockefeller University, and Paul Waggoner of the Connecticut Agricultural Experiment Station:

Globally, the production of a given quantity of crop requires 65% less land than it did in 1961, thanks to fertilizers, tractors, pesticides, better varieties and other factors. Even corrected for different kinds of crops, the acreage required is falling at 2% a year.

In the U.S., the total corn yield and the total corn acreage tracked each other in lock step between 1870 and 1940-there was no change in average yield per acre. But between 1940 and 2010, corn production almost quintupled, while the acreage devoted to growing corn fell slightly. Similar divergences appeared later in other countries. Indian wheat production increased fivefold after 1970, while wheat acreage crept up by less than 1.5 times. Chinese corn production rose sevenfold over the same period while corn acreage merely doubled.

Yet the amount of farmland in the world was still rising until recently. The reason is that increased farm productivity has been matched by rising demand for food, driven by population growth and swelling affluence. But the effects of these trends are waning.

[. . .]

Even with these cautious assumptions, the researchers find that over the next 50 years people are likely to release from farming a land area “1½ times the size of Egypt, 2½ times the size of France, or 10 Iowas, and possibly multiples of this amount.”

Indeed, the authors find that this retreat from the land would have already begun but for one factor so lunatic that they cannot imagine it will not be reversed soon: biofuels. If the world had not decided to subsidize the growing of energy crops on 3.4% of arable land, then absolute declines in the acreage of arable land “would have begun during the last decade.” The prospect of “the restoration of vast acreages of Nature” is enticing for nature lovers.

Climatic witchcraft

Filed under: Environment, History, Media, Science — Tags: , , , , — Nicholas @ 10:23

No offense intended to practitioners of witchcraft intended:

Superstition about the weather in particular is hardly surprising, given the awesome power of nature. Witnessing storms, lightning and even the daily rising and setting of the sun surely induced fear and wonder in primitive cultures. The same fear and wonder are what warmists exploit today in linking weather extremes to global warming.

Scholars tell us that weather superstition often found expression in ritual human sacrifice. The Mayans, for instance, tossed victims into a limestone sinkhole to appease the rain god Chaac.

And it’s only a few centuries since superstition over the climate led to intensive witch hunts and widespread executions, usually by burning, for witchcraft.

University of Chicago economist Emily Oster demonstrated in 2004 that the most active era of witchcraft trials in Europe coincided with the Little Ice Age. Since then, other researchers have argued that chilly weather may have precipitated the Salem witch trials in the 1690s — one of the coldest periods of that epoch.

It was widely believed during the late Middle Ages that witches were capable of controlling the weather with their magic powers, and thus cause storms that could destroy harvests and hobble food production.

[. . .]

Our obsession with weather extremes has reached such heights that it has become a knee-jerk reaction for climate-change alarmists to ascribe any unusual weather event at all to global warming. So they tell us that heat waves, floods, harsh winters, dust storms — even wildfires — are all the result of man-made CO2. But a check of records from, say, the 1930s or the 1950s, when the CO2 level was much lower than now, reveals that such events are nothing new.

Climate-change skeptics might be regarded as modern-day witches because they think that global warming comes from natural forces. However, it’s superstitious alarmists, who believe that extreme weather originates in our CO2 emissions and who have a dread of impending disaster, who are really the witches.

No, we’re not running out of phosphorus (phosphate) and potassium (potash)

Filed under: Economics, Environment, Media — Tags: , , , — Nicholas @ 09:58

The most recent outbreak of the-sky-is-falling, we’re-at-peak-whatever panic mongering is debunked by Vaclav Smil:

Jeremy Grantham, a well-known presence in the financial world, recently published a World View column in the journal Nature in which he concludes that, “simply, we are running out” of almost all commodities whose consumption sustains modern civilization. There is nothing new about such claims, and since the emergence of a vocal global peak oil movement during the late 1990s, many other minerals have been added to the endangered list. Indeed, there is now a book called Peak Everything. What makes Grantham’s column – published under the alarmist headline “Be Persuasive. Be Brave. Be Arrested (If Necessary)” – worth noticing, and deconstructing, is that he puts his claims in terms more suitable for tabloids than for one of the world’s oldest and most prestigious scientific weekly magazines.

His direst example is “the impending shortage of two fertilizers: phosphorus (phosphate) and potassium (potash). These two elements cannot be made, cannot be substituted, are necessary to grow all life forms, and are mined and depleted. It’s a scary set of statements…. What happens when these fertilizers run out is a question I can’t get satisfactorily answered and, believe me, I have tried.” Well, he could have tried just a bit harder: an Internet search would have led him, in mere seconds, to “World Phosphate Rock Reserves and Resources,” a study published in 2010 by the International Fertilizer Development Center (IFDC) and funded by the U.S. Agency for International Development.

This detailed assessment of the world’s phosphate reserves (that are the part of a wider category of resources that is recoverable with existing techniques and at acceptable cost) concluded that they are adequate to produce fertilizer for the next 300 to 400 years. As with all mineral resource appraisals (be they of crude oil or rare earths), the study’s conclusions can be criticized and questioned, and the statement by the Global Phosphorus Research Initiative is perhaps the best document of that kind. But even the most conservative interpretation of IFDC’s assessment shows that phosphates have a reserve/production ratio well in excess of 100 years, higher than that of many other critical mineral resources.

The Doha climate change conference is “like an absurdist flash mob”

Filed under: Environment, Media, Middle East, Politics — Tags: , , , , — Nicholas @ 09:33

Rob Lyons explains why the current meeting in Doha isn’t getting the same media love that earlier conferences have been able to depend upon:

It’s like a fly banging its head against a window pane, desperately trying to get to the other side and uncomprehending as to why it never succeeds. Except this is a 17,000-strong swarm of flies taking part in its annual exercise in futility. Yes, there’s another UN climate conference going on, though you might well have missed it.

The eighteenth Conference of the Parties to the UN Framework Convention on Climate Change — there’s a good reason they call it COP18 — is taking place in Doha, the capital of Qatar. The small Arab state is, by some measures, the richest country in the world per head of population, a position built on the fact that it has the third-largest reserves of natural gas in the world. The conference has been running since 26 November and is due to end on Friday. But no one is predicting any kind of dramatic deal.

Which is a bit of a problem for those who run this peculiar show because another thing that ends soon is the Kyoto Protocol. Signed 15 years ago in Japan, the protocol aimed to reduce greenhouse gas emissions in 37 industrialised countries and the EU to a level five per cent below 1990 levels for the period from 2008 to 2012. There’s no sign of a replacement — which, to be meaningful, really needs to include big developing countries like China, India and Brazil — just endless talks about talks. At last year’s event — COP17 in Durban, South Africa — there was an agreement to negotiate a ‘protocol, legal instrument, or an agreed outcome with legal force applicable to all Parties’ by 2015, to take effect by 2020. As a Greenpeace representative bemoaned then: ‘Right now the global climate regime amounts to nothing more than a voluntary deal that’s put off for a decade.’

It’s all a far cry from the Copenhagen talks in 2009. US president Barack Obama agreed to attend, which meant that there was real anticipation of a major deal. Yet Obama came and Obama went, and nothing of substance was agreed. And so the process has trundled on in its own, other-worldly way. COP18 sees thousands of the kind of people who think we’re screwing up the planet by flying around the world, flying around the world in order achieve bugger all in a country, Qatar, made rich by the very fossil fuels the delegates want left in the ground. It’s like an absurdist flash mob.

The not-so-hidden Agenda 21

Filed under: Books, Bureaucracy, Environment, Government, Media — Tags: , , , , — Nicholas @ 09:07

In the Libertarian Enterprise, John Walker talks about the UN’s Agenda 21:

In 1992, at the United Nations Conference on Environment and Development (“Earth Summit”) in Rio de Janeiro, an action plan for “sustainable development” titled “Agenda 21” was adopted. It has since been endorsed by the governments of 178 countries, including the United States, where it was signed by president George H. W. Bush (not being a formal treaty, it was not submitted to the Senate for ratification). An organisation called Local Governments for Sustainability currently has more than 1200 member towns, cities, and counties in 70 countries, including more than 500 in the United States signed on to the program. Whenever you hear a politician talking about environmental “sustainability” or the “precautionary principle”, it’s a good bet the ideas they’re promoting can be traced back to Agenda 21 or its progenitors.

When you read the U.N. Agenda 21 document (which I highly encourage you to do—it is very likely your own national government has endorsed it), it comes across as the usual gassy international bureaucratese you expect from a U.N. commission, but if you read between the lines and project the goals and mechanisms advocated to their logical conclusions, the implications are very great indeed. What is envisioned is nothing less than the extinction of the developed world and the roll-back of the entire project of the enlightenment. While speaking of the lofty goal of lifting the standard of living of developing nations to that of the developed world in a manner that does not damage the environment, it is an inevitable consequence of the report’s assumption of finite resources and an environment already stressed beyond the point of sustainability that the inevitable outcome of achieving “equity” will be a global levelling of the standard of living to one well below the present-day mean, necessitating a catastrophic decrease in the quality of life in developed nations, which will almost certainly eliminate their ability to invest in the research and technological development which have been the engine of human advancement since the Renaissance. The implications of this are so dire that somebody ought to write a dystopian novel about the ultimate consequences of heading down this road.

Hurricane Sandy, storm surges, and superstition

Filed under: Environment, Media, Science — Tags: , , , , , — Nicholas @ 09:16

In sp!ked, Dominic Standish looks at how some recent extreme weather incidents are being attributed to climate change/global warming without sufficient scientific evidence:

Hurricane Sandy brought havoc in the Caribbean, especially Haiti, and caused approximately 60 deaths. Then the storm hit the US east coast; New York experienced exceptional floods and at least 40 people lost their lives. Next, Venice in Italy witnessed high flooding on 11 November, when the city’s tide measurements reached their sixth-highest level for 140 years. No one died from these floods in Venice, but — like Haiti and New York — the economic impact was significant.

Global warming was widely blamed for the flooding, yet in all three cases flooding was principally caused by storm surges. In the Caribbean and America, there was an unfortunate convergence of weather systems creating storm surges. As Hurricane Sandy swirled north in the Atlantic and towards land, a wintry storm headed towards it from the West and cold air was blowing south from the Arctic. After the hurricane devastated parts of the Caribbean, it moved towards the north-east of the US, pushing water up the estuaries of New York into the city. Venice’s floods were unconnected to Hurricane Sandy, but were also caused by high winds creating storm surges pushing water through the three inlets between the sea and the Venetian lagoon towards the city. Subsidence over the past century has made Venice more susceptible to storm surges. Nevertheless, after 70 per cent of Venice was under water on 11 November, Italy’s environment minister, Corrado Clini, insisted that global climate change was to blame.

Although storm surges were the cause of the floods in all three locations, global warming was widely identified as the culprit. Of course, we cannot ignore climate change. The Intergovernmental Panel on Climate Change (IPCC) established in 2007 that there was a global temperature rise of 0.74 degrees Celsius between 1906 and 2005, which added to global sea levels rising by an average rate of 1.8 millimetres per year from 1961. We need to have an open debate about climate change and its relationship with bad weather events. Some argue that climate change has increased hurricanes and storm surges, while others suggest there is insufficient evidence to prove this link. Whether climate change impacts on the frequency and strength of hurricanes remains uncertain, yet global warming has definitely been deployed as a superstitious narrative to close down discussion.

Update: Of course, the storm damage will eventually repaired and the federal government will pay the lion’s share of the costs. This is one of the bigger causes of rising costs due to storm damage along the US coastline: properties that are more exposed to damage keep getting rebuilt. Here’s an example from Dauphin Island, Alabama:

The western end of this Gulf Coast island has proved to be one of the most hazardous places in the country for waterfront property. Since 1979, nearly a dozen hurricanes and large storms have rolled in and knocked down houses, chewed up sewers and water pipes and hurled sand onto the roads.

Yet time and again, checks from Washington have allowed the town to put itself back together.

Across the nation, tens of billions of tax dollars have been spent on subsidizing coastal reconstruction in the aftermath of storms, usually with little consideration of whether it actually makes sense to keep rebuilding in disaster-prone areas. If history is any guide, a large fraction of the federal money allotted to New York, New Jersey and other states recovering from Hurricane Sandy — an amount that could exceed $30 billion — will be used the same way.

Tax money will go toward putting things back as they were, essentially duplicating the vulnerability that existed before the hurricane.

The BBC’s 28 secret climate change advisors

Filed under: Britain, Environment, Law, Media — Tags: , , , , — Nicholas @ 10:49

The BBC has been prominent among media outlets for their relentless proclamations on the dangers of climate change. Despite the BBC’s charter requiring them to provide balanced coverage, in this particular area they have been cheerleaders for one particular message: that climate change is DOOM!

In 2006, the BBC convened a panel of climate change experts to advise them on the topic, and the corporation took the advice of that panel to heart and has been pushing the climate change = disaster meme ever since. Blogger Tony Newbery submitted a FOI request to find out who had been on the panel which had swung the BBC so far away from their charter, but his request was denied. Not just denied, but fought out in court at an estimated cost of £40,000 per day.

The BBC won in court, but the information was released by someone else:

Sadly for the BBC, another enterprising blogger called Maurizio Morabito unearthed the details anyway and published them on Monday via the website Watts Up With That?

So who were all these ‘best scientific experts’ who did so much to shape the BBC’s climate policy (and by extension, one fears, government policy too…)? Well, two were from Greenpeace; one was from Stop Climate Chaos; one was a CO2 reduction expert from BP; one was from Npower Renewables; one came from the left-leaning New Economics Foundation… Only five of those present could, in any way, be considered scientists with disciplines even vaguely relevant to ‘climate change’. And of these, every one had a track record of climate alarmism. No wonder the BBC tried so hard to keep the list of 28 a secret. Its claim that its policy change was based on the ‘best scientific’ expertise turns out to have been a massive lie.

“Carbon sequestration in peatland may be one of the main reasons why ice age conditions have occurred time after time”

Filed under: Environment, Science — Tags: , , — Nicholas @ 00:01

Overall, global cooling is far more to be feared than global warming … and we may be seeing the conditions that would create a new ice age in the near future:

A group of Swedish scientists at the University of Gothenburg have published a paper in which they argue that spreading peatlands are inexorably driving planet Earth into its next ice age, and the only thing holding back catastrophe is humanity’s hotly debated atmospheric carbon emissions.

“We are probably entering a new ice age right now. However, we’re not noticing it due to the effects of carbon dioxide,” says Professor of Physical Geography Lars Franzén, from the Department of Earth Sciences at Gothenburg uni.

[. . .]

The scientists have calculated that the potential is there for Swedish peatlands to triple in extent, enormously increasing their carbon sink effect. By extrapolating to include the rest of the world’s high-latitude temperate areas – the parts of the globe where peatland can expand as it does in Sweden – they project the creation of an extremely powerful carbon sink. They theorise that this is the mechanism which tends to force the Earth back into prolonged ice ages after each relatively brief “interglacial” warm period.

“Carbon sequestration in peatland may be one of the main reasons why ice age conditions have occurred time after time,” says Franzén.

With no other factors in play, the time is about right for the present interglacial to end and the next ice age to come on. Indeed, Franzén and his crew think it has barely been staved off by human activity

Caution should be exercised with this as with all climate-model-based predictions: our models are still not good enough to be dependable, so this is no more something to panic about than the “global warming” scare of the last decade. It is something to consider and to try to develop better models and collect more data to support or contradict the findings.

The Swiss children of Malthus

Filed under: Environment, Europe, Politics — Tags: , , , , , — Nicholas @ 08:59

In sp!ked, Patrick Hayes points out the odd way that Malthusians and xenophobic far-right political groups converge:

For greens, the ends will always justify the means when it comes to saving the planet. In the UK, they have opportunistically latched themselves on to left-wing movements to try to gain purchase with a broader public. But, as Swiss campaign group Ecology and Population (EcoPop) has demonstrated, in an attempt to pursue their Malthusian goals, greens can be equally happy tapping into the anti-immigrant rhetoric of the far right.

In a stunt last week, members of EcoPop carried dozens of cardboard boxes into the Swiss chancellery which contained 120,700 certified signatures calling for immigration into Switzerland to be capped at 0.2 per cent of the resident population. Under Swiss law, this means that a referendum will now be held on the proposal. Such a move trumps even the efforts of the far-right Swiss People’s Party, which has long lobbied for greater immigration controls.

But these greens aren’t mobilising for an immigration clampdown with banners claiming ‘keep the darkies out’ as right-wing groups have done in the past. Nor are they using dodgy, discredited scientific arguments to justify racial superiority, wielding books like Madison Grant’s The Passing of The Great Race for evidence.

No, instead EcoPop delivers its demands for immigration curbs carrying a banner asking: ‘How many people can the Earth tolerate?’ The group’s members use the (equally dodgy and discredited) Malthusian science of population growth and babble on about our ‘finite planet’. And they have reportedly been strongly influenced by the theories of US Malthusian Paul Ehrlich, author of The Population Bomb.

EcoPop bends over backwards to claim that it is not singling out particular races when advocating its policies. According to the BBC, it claims to be ‘opposed to all forms of xenophobia and racism’. But, the group says, ‘Switzerland must limit immigration to avoid urbanisation and to preserve agricultural land’.

You could almost believe that EcoPop is just a bunch of backward-thinking NIMBYish Luddites wanting to stop a flood of immigrants from destroying what it sees as a rural idyll — until you see what the group has tacked on to its proposed referendum for immigration caps. EcoPop slipped an additional clause into the referendum calling for a tenth of all foreign aid to be used ‘for birth-control measures abroad’. (It’s highly questionable how many people would have signed a petition for that alone.)

So it’s not enough to keep foreigners out of Switzerland, then, it’s also necessary to keep them from breeding too much in their own countries as well. And the fact that most of the aid will go towards stopping poor black and brown families from breeding too much suggests that if they’re not intentionally being racist, then EcoPop’s members should really think very hard about how they come across.

Matt Ridley on the real threat to our ecology

Filed under: Britain, Bureaucracy, Environment — Tags: , , , — Nicholas @ 00:01

It’s not global warming:

I’m pessimistic about the ash trees. It seems unlikely that a fungus that killed 90 per cent of Denmark’s trees and spreads by air will not be devastating here, too. There is a glimmer of hope in the fact that ash, unlike elms, reproduce sexually so they are not clones — uniformly vulnerable to the pathogen. But it’s only a glimmer: tree parasites, from chestnut blight to pine beauty moth, have a habit of sweeping through species pretty rampantly, because trees are so long-lived they cannot evolve resistance in time.

The Forestry Commission’s apologists are pleading ‘cuts’ as an excuse for its failure to do anything more timely to get ahead of the threat, but as a woodland owner I am not convinced. An organisation that has the time and the budget to pore over my every felling or planting application in triplicate and come back with fussy and bossy comments could surely spare a smidgen of interest in looming threats from continental fungi that have been spreading out from Poland for 20 years. The commission was warned four years ago of the problem.

Here’s what the commission was up to instead. Just last year, I received a letter from the Forestry Commission demanding access to survey one of my woods to answer the question ‘what are the forecasts for timber, biomass and carbon?’ in order to ‘help the United Kingdom meet international commitments, such as reporting for the Global Forest Resources Assessment and the Ministerial Conference on the Protection of Forests in Europe (MCPFE)’.

Notice the Sir Humphrey-esque circular argument: surveys must be done so that the results can be reported to assessment meetings. In other words, as far as I can tell, the Forestry Commission’s priority has been, as in so many government bodies, to supply talking points for the international carbon-obsessed bureaucracy. The implicit assumption here, of course, is that climate change is the greatest threat to Britain’s trees, when in reality far greater threats come from diseases carried around by foresters themselves.

This is happening throughout the world of nature conservation. A climate fetish has sucked all the oxygen from the real threats to species and habitats — indeed it has actually begun to make those threats worse.

The economic problem with recycling is that it’s the inverse of retail value

Filed under: Economics, Environment, Technology — Tags: — Nicholas @ 00:01

Tim Worstall at Forbes:

We all understand how pricing in the retail chain goes. Each unit of something in a shipload of them is worth less than each unit when there’s only a container of them, and so it goes on. As we get closer to the retail point each unit rises in value. As we break down the shipment from tens of thousands of units, to a truckload, then a pallet load, finally to the one single item sitting on the store shelf. If you agree to purchase 5,000 iPads you’ll expect to pay less for each one than if you tried to buy just one.

We get that: the thing about recycling is that pricing works entirely the other way around. To a reasonable approximation the value of one unit of anything for recycling is worth nothing. The value of each of 1,000 units in the same place is higher than that solitary one. One scrap car in the middle of a field isn’t worth much if anything. 1,000 cars in a scrap yard might be worth $300 a tonne for the steel content (don’t take these numbers too seriously by the way, they’re examples only). Precious metals refining, scrap metal, recycling: they all share this same economic point. The more of something you have then the more each unit of that something is worth.

[. . .]

… the way we tend to look at the economics of recycling. We hear a great deal about how recycling plastics, or cooking oil, metals, electronics, you name it we hear the same thing, “saves resources”. Sometimes this is absolutely true. Other times however what we get shown is the value of the actual recycling being done. And we’re not told about the costs of collecting what is to be recycled. And as above it’s those costs of collection that are really the key to the whole enterprise.

Just as an example there’s value in 1,000 tonnes of used plastic bags. Among other things you can burn them in a power station and get some energy. Great: but what is the cost of collecting enough used plastic bags to make 1,000 tonnes? That’s the part that seems not to get into the calculations that our green friends present to us.

Cash4Gold seems to have gone under because the collection costs of the materials were higher than the value of recycling those materials. What’s really rather worrying about the larger recycling movement is that this can be/is often true of other materials. But because we don’t properly account for the collection costs we don’t see this as clearly as we do in the accounts of a (failed) for profit company (OK, would be for profit company).

Twenty million broken windows

Filed under: Economics, Environment, Media — Tags: , , — Nicholas @ 09:03

At Forbes, Tim Worstall patiently explains that the damage from Hurricane Sandy (or any major storm) will appear to boost GDP, because it only measures money spent to repair damage, not the costs incurred or the opportunities foregone because of the damage:

We know very well that Hurricane (or Frankenstorm as some are calling it) Sandy will leave a trail of destruction across parts of the US today. There will almost certainly be deaths, as there have been in the hurricane’s passage across the Caribbean. And there will also be a boost to the US economy. Which is really evidence of quite how wrong we are in the way that we measure the economy.

[. . .]

The problem with this is that it is only true because of the way that we calculate GDP. In our working of the numbers we assume that it’s final consumption at market prices: that is, the value that consumers put on everything. However, this is not true of government spending. It’s very difficult indeed to work out what government spending is actually worth: for as we’ve not a choice in it then there’s no market price nor accurate valuation from the people who actually get whatever is produced. Some government spending is most certainly worth more than the actual amount spent. The court system say: a pre-requisite of our having a complex society at all. Other parts not so much: what is the true value of a diversity adviser for example? So what we actually do is value all government spending, for GDP purposes, at the cost of that actual spending. Government spends $100, GDP goes up by $100. That’s just how we define it. This can cause amusement in measuring the success of welfare programs for example. Even Census admits that some of the people who receive Medicaid, or food stamps, value what they receive at less than the cost of providing it.

[. . .]

Now imagine that Hurricane Sandy does $10 billion of damage to that wealth (for our purposes it doesn’t matter whether it’s $100 billion or $1 trillion. Although this obviously matters to everyone except for the purposes of this example). The US is now worth $99.990 Trillion. GDP might rise to $15.1 trillion as we repair that damage. But we’re not in fact any richer at all: despite the fact that GDP has gone up. What has actually happened is that some of our stock of wealth has been destroyed and we’re having to do more work in order to rebuild it. This is exactly the same as our pollution example. We’re measuring what we produce but not the capital stock of what we have (or had).

Yes, the rebound from Sandy may well provide a boost to the economy. But that’s a function of the way that we measure that economy, not a real boost in our general wealth.

Got Milk (mutation)?

Filed under: Environment, Food, Health, History, Science — Tags: , — Nicholas @ 12:33

Lactose intolerance is part of humankind’s genetic inheritance, which is why the mutation that allowed (some) adult humans to digest milk is of great interest to geneticists:

A genetic mutation appeared, somewhere near modern-day Turkey, that jammed the lactase-production gene permanently in the “on” position. The original mutant was probably a male who passed the gene on to his children. People carrying the mutation could drink milk their entire lives. Genomic analyses have shown that within a few thousand years, at a rate that evolutionary biologists had thought impossibly rapid, this mutation spread throughout Eurasia, to Great Britain, Scandinavia, the Mediterranean, India and all points in between, stopping only at the Himalayas. Independently, other mutations for lactose tolerance arose in Africa and the Middle East, though not in the Americas, Australia, or the Far East.

In an evolutionary eye-blink, 80 percent of Europeans became milk-drinkers; in some populations, the proportion is close to 100 percent. (Though globally, lactose intolerance is the norm; around two-thirds of humans cannot drink milk in adulthood.) The speed of this transformation is one of the weirder mysteries in the story of human evolution, more so because it’s not clear why anybody needed the mutation to begin with. Through their cleverness, our lactose-intolerant forebears had already found a way to consume dairy without getting sick, irrespective of genetics.

A “high selection differential” is something of a Darwinian euphemism. It means that those who couldn’t drink milk were apt to die before they could reproduce. At best they were having fewer, sicklier children. That kind of life-or-death selection differential seems necessary to explain the speed with which the mutation swept across Eurasia and spread even faster in Africa. The unfit must have been taking their lactose-intolerant genomes to the grave.

Milk, by itself, somehow saved lives. This is odd, because milk is just food, just one source of nutrients and calories among many others. It’s not medicine. But there was a time in human history when our diet and environment conspired to create conditions that mimicked those of a disease epidemic. Milk, in such circumstances, may well have performed the function of a life-saving drug.
