When is plastic better for the environment than paper?

Filed under: Environment, Technology — Tags: , — Nicholas @ 12:29

The answer: when the product gets dumped in a landfill.

Stateside boffins say that, contrary to popular perception, it would often be better for the planet if people avoided using biodegradable products compliant with the recommended US government guidelines.

This is because biodegradable wastes — for instance cardboard cups, “eco friendly” disposable nappies, various kinds of shopping and rubbish bags etc — often wind up in landfill, where they will degrade and emit methane. Methane is, of course, a vastly more powerful greenhouse gas than CO2, so it is seen as important to prevent it getting into the atmosphere.

[. . .]

The answer, according to Barlaz, is to get away from the idea that rapid decomposition is always a good idea — especially on things which won’t be recycled much but will probably wind up in landfill, for instance disposable nappies, fast-food packaging etc.

“If we want to maximize the environmental benefit of biodegradable products in landfills,” Barlaz says, “we need to both expand methane collection at landfills and design these products to degrade more slowly — in contrast to FTC guidance.”

More on the Greenland settlements

Filed under: Americas, Environment, History — Tags: , , , — Nicholas @ 12:08

In a follow-up to yesterday’s post on the end of the Viking settlements in Greenland, Sonya Porter provides more historical background:

In 891 AD. Eric The Red set off from Iceland with a few followers to explore a land to the west which they had probably spotted some time before while sailing out in their longboats, and then returned three years later with about 500 fellow Vikings. At first they settled on the south-east coast, close to the tip of this new land and then, as the population grew, created a further settlement to the south-west. They called their new home ‘Greenland’.

It has been said that this name was a ‘spin’, a publicity stunt to entice more Vikings to come to join the new settlers, but this would have been pointless if it had been impossible for them to survive. They must at least have been able to create their own dwellings, build their own fires, make their own clothes and above all, grow their own food. The settlers might have been able to trade such things as polar bear-skins and fox furs for iron and other necessities on occasional trips to Europe, but their compatriots in Denmark and Iceland would have been neither able nor willing to row their longboats out each month with groceries.

At present, the temperatures in Greenland range from a maximum of 7C in July to -9C in January. This is too cold for grain such as wheat and even rye to grow and ripen in the short summer of such northern latitudes. Nor are sheep and cattle happy at those temperatures. Hill sheep might be able to nibble away at moss and short grass, but cattle need lush meadows and hay to fatten and live through a winter. Solid wood is needed for building, boat building and warmth, but only bushes and such weak trees as birch now grow in Greenland.

In 1991, two caribou hunters stumbled over a log on a snowy Greenland riverbank, an unusual event because Greenland is now above the treeline. (1) Over the past century, further archaeological investigations found frozen sheep droppings, a cow barn, bones from pigs, sheep and goats and remains of rye, barley and wheat all of which indicate that the Vikings had large farmsteads with ample pastures. The Greenlanders obviously prospered, because from the number of farms in both settlements, whose 400 or so stone ruins still dot the landscape, archaeologists guess that the population may have risen to a peak of about five thousand. They also built a cathedral and churches with graves which means that the soil must have been soft enough to dig, but these graves are now well below the permafrost (2).

A bit of climate-change panic juxtaposition

Filed under: Americas, Environment, History — Tags: , , , , , — Nicholas @ 17:26

First, the panic:

In a world of climate change, freak storms are the new normal. Newsweek‘s Sharon Begley on why we’re unprepared for the harrowing future, and how adapting to the inevitable might be our only option.
[. . .]
From these and other extreme-weather events, one lesson is sinking in with terrifying certainty. The stable climate of the last 12,000 years is gone. Which means you haven’t seen anything yet. And we are not prepared.

And, in the interests of balance, the eeeevil climate change denier:

Greenland’s early Viking settlers were subjected to rapidly changing climate. Temperatures plunged several degrees in a span of decades, according to research from Brown University. A reconstruction of 5,600 years of climate history from lakes near the Norse settlement in western Greenland also shows how climate affected the Dorset and Saqqaq cultures. Results appear in Proceedings of the National Academy of Sciences.

PROVIDENCE, R.I. [from Brown University] — The end of the Norse settlements on Greenland likely will remain shrouded in mystery. While there is scant written evidence of the colony’s demise in the 14th and early 15th centuries, archaeological remains can fill some of the blanks, but not all.

What climate scientists have been able to ascertain is that an extended cold snap, called the Little Ice Age, gripped Greenland beginning in the 1400s. This has been cited as a major cause of the Norse’s disappearance. Now researchers led by Brown University show the climate turned colder in an earlier span of several decades, setting in motion the end of the Greenland Norse.
[. . .]
The researchers also examined how climate affected the Saqqaq and Dorset peoples. The Saqqaq arrived in Greenland around 2500 B.C. While there were warm and cold swings in temperature for centuries after their arrival, the climate took a turn for the bitter beginning roughly 850 B.C., the scientists found. “There is a major climate shift at this time,” D’Andrea said. “It seems that it’s not as much the speed of the cooling as the amplitude of the cooling. It gets much colder.”

The Saqqaq exit coincides with the arrival of the Dorset people, who were more accustomed to hunting from the sea ice that would have accumulated with the colder climate at the time. Yet by around 50 B.C., the Dorset culture was waning in western Greenland, despite its affinity for cold weather. “It is possible that it got so cold they left, but there has to be more to it than that,” D’Andrea said.

NASA’s changing goals for Orion

Filed under: Politics, Space, USA — Tags: , , , , — Nicholas @ 09:56

The ever-sarcastic Lewis Page looks at how NASA has been trying to reposition their planned Orion spaceship:

NASA has declared that its pork-tastic Orion moonship — whose primary mission disappeared with President Obama’s decision that there will be no manned US return to the Moon — is now to be a “deep space transportation system”, suggesting that the agency plans to send it on missions beyond Earth orbit.

It remains unclear how the newly-renamed Multi Purpose Crew Vehicle (MPCV) will travel into space, when it will do so and what its destination might be — though a near-Earth asteroid is a likely possibility. A major reason for Orion’s continued survival appears to be ignoble porkbarrel politics — but there is a tantalising possibility that it might fly beyond Earth orbit in the relatively near future.

What Page calls NASA’s “pork map” shows why the MPCV has strong, bi-partisan political support regardless of its actual utility for the space program:

Regardless of the political support, however, the most likely view of US federal government finances indicates that Orion/MPCV won’t be viable in the proposed timeframe. There’s a non-governmental choice, however:

Famous geekbiz-kingpin Elon Musk and his upstart rocket company SpaceX have come from nowhere in just eight years to successfully test-fly their brand new and very cheap Falcon 9 rocket and Dragon capsule, already apparently quite capable of performing the ISS supply mission. Only a few years ago, many in NASA and the established industry were arguing that this would never happen.

It’s also no secret that Musk and SpaceX are working on a new Merlin 2 rocket engine, much bigger than the current Merlin 1 which propels the Falcon 9. A multicore heavy lifter based on Merlin 2 would be in the 100-tonne-plus realm required to mount a Mars mission, and will surely be the cheapest offering competing at the 2015 heavy lift Mars-rocket decision.

More on the Anglo-Danish Marmite affair

Filed under: Britain, Bureaucracy, Europe, Food, Health — Tags: , , , , — Nicholas @ 10:34

Colby Cosh rounds up the details on the Marmite affair:

Nothing stirs the blood of the British like a nice slapfight over European regulation, and this goes double when food is involved. The UK press has found its latest excuse for tut-tutting and finger-waggling in the unlikeliest of places: at the bottom of the squat, distinctive little jar in which the vile breakfast spread Marmite is sold. This week, English-language journals in Denmark reported that the Scandinavian kingdom’s food regulator was having the dark brown yeast extract cleared from the shelves of shops which serve Brit expatriates.

The British reared up as one, displaying a spirit of indignant unity. “What have the Danes ever done for global cuisine?” thundered the Belfast Telegraph, breaking Godwin’s Law into splinters over its knurled Ultonian knee. (Unfortunately, a good answer might be “Not given it Marmite, at any rate.”) Fans of the quasi-foodstuff gathered on Facebook to form a “Marmite army”. Social campaigners used the ban to call attention to dubious patches in Denmark’s record on human rights and environmentalism.

As he points out, nobody at the Danish food nanny office suddenly issued a ban: technically Marmite had never been cleared for import at all. So it’s just a matter of filling in a form or two and Bob’s your uncle? Not quite:

Marmite’s status as a “fortified food” has apparently only just been noticed, and the DVFA says that “it has not received an application for marketing in Denmark of Marmite or similar products with added vitamins or minerals.” A glance at the DVFA’s procedure for obtaining approval to market these foods reveals why brand owner Unilever might not be in such a hurry to file. (And it also reveals that free-trade fanatics like me should probably rein in their admiration for the EU’s trade barriers just a little.) The agency not only requires compliance with EU-wide regulations, but insists that each product pass an “individual risk assessment” performed using a made-in-Denmark scientific procedure.

More on resveratrol in red wine

Filed under: Health, Science, Wine — Tags: — Nicholas @ 15:04

Every few weeks, there’s another study result published (or, in some cases, mangled in the publishing) about the benefits to human health from the resveratrol in red wine, but few of them will go this far:

Drink 8 bottles of wine, you’ll be unharmed if hit by Mike Tyson
True medical fact: Trials with boxers underway

Top boffins in Texas believe they will soon provide solid proof of an astonishingly useful biological fact: that if you drink eight bottles of red wine you can be punched in the head by a professional heavyweight boxer and it will do you no harm at all.

We’re paraphrasing slightly, of course.

The Danish Marmite affair thickens

Filed under: Britain, Bureaucracy, Europe, Food, Health — Tags: , , , — Nicholas @ 09:50

Lester Haines has the latest on the plight of ex-pat Brits suffering under a dictatorial food regime in Denmark:

According to this official statement, neither Marmite nor its Oz rival Vegemite are banned in Denmark, because they’ve never actually been approved for sale.

A 2004 law controls the distribution of products with “added vitamins, minerals or other substances”, and in order to punt such foodstuffs, they “need to be approved by the Danish Veterinary and Food Administration before the product can be marketed”.

[. . .]

In effect, then, those shops selling Marmite are dealing in unauthorised enhanced substances.

We and the Daily Mail have no doubt that any attempt to legalise Marmite would be met with a swift rejection, in defiance of EU directives on free trade. As Copenhagen-based expat Lyndsay Jensen put it: “They don’t like it because it’s foreign. But if they want to take my Marmite off me, they’ll have to wrench it from my cold dead hands.”

It’s been said that Marmite is an “acquired taste”, but Denmark’s health regulators are moving quickly to ensure that Danes never have the opportunity to develop that taste. Of course, like most other forms of prohibition, it might actually increase the attractiveness of the “forbidden fruit”.

Denmark has a long coastline, so smuggling in the little black jars across the North Sea would be quite possible . . .

Here’s a different way to pay for socialized medicine

Filed under: Economics, Government, Health, USA — Tags: , , — Nicholas @ 09:35

Kevin Drum has an interesting proposal in Mother Jones:

So here’s an idea: why not reform Medicare by means testing it? Conservatives should love this idea.

Here’s how it works. Basically, we leave Medicare alone. Oh, we can still go ahead with some of the obvious reforms. Comparative effectiveness research is a no-brainer for anyone who’s not part of the Republican leadership. Ditto for some of the delivery reforms on the table. Or allowing Medicare to negotiate for lower prices. It would be great if that stuff works. But if it doesn’t, then people will need to pay more for their care. So why not have dead people pay? They don’t need the money any more, after all.

So Medicare stays roughly the same, but every time you receive medical care you also get a bill. You don’t have to pay it, though. It’s just there for accounting purposes. When you die, the bill gets paid out of your estate. If your estate is small or nonexistent, you’ve gotten lots of free medical care. If it’s large, you’ll pay for it all. If you’re somewhere in between, you’ll end up paying for part of the care you’ve received.

Obviously this gives people incentives to spend all their money before they die. That’s fine. I suspect they wouldn’t end up spending as much as you’d think. What it does mean, though, is that Medicare has first claim on their estate, not their kids. But that seems fair, doesn’t it?

It has the virtue of acknowledging that free healthcare isn’t actually “free” at all.

Australia: leading the charge to our over-Nannied future

Filed under: Australia, Bureaucracy, Health, Liberty — Tags: , , , — Nicholas @ 12:31

There once was a time when the popular image of Australia celebrated its rugged, independent, free-spirited approach to life. It’s hard to recognize that in today’s Nanny State paradise:

Last week, the Preventative Health Taskforce published a report which, in its words, launched a ‘crackdown’ on drinking, smoking and the eating of ‘energy-dense, nutrient-poor’ food. This report made 122 recommendations, called for 26 new laws and proposed establishing seven new agencies to change the behaviour of Australians. To take just a few examples related to tobacco, the Taskforce called for the price of 30 cigarettes to rise to ‘at least $20’ (£13) by 2013, for a ban on duty-free sales, a ban on vending machines and a ban on smoking in a host of places including multi-unit apartments, private vehicles and ‘outdoors where people gather or move in close proximity’. They even contemplate a ban on filters and the prohibition of additives that enhance the palatability of cigarettes.

As in so many countries, Australia’s anti-smoking campaign has acted as a Trojan horse in the effort to fundamentally change the relationship between citizen and state. By no means does it end with tobacco. The Taskforce also wants to ban drinks advertising during programmes that are watched by people under 25 — a category so broad as to include virtually every programme — and calls for graphic warnings similar to those now found on cigarette packs to be put on bottles of beer. It also wants the government to establish ‘appropriate portion sizes’ for meals, to tax food that is deemed unhealthy and to hand out cash bonuses to those who meet the state’s criteria of a healthy lifestyle.

And it’s not just the booze and ciggies getting the full Nanny treatment, either. Australia is very concerned about the internet browsing and video game habits of the citizens:

It is the professed concern for the well-being of children that props up so much authoritarian legislation in both hemispheres. This does not just apply to smoking, nor even health issues in general. Australia has a unenviable record of internet censorship, for example, and a national website filter has been proposed to protect children from pornography and gambling. It also has a longer list of banned video games than any other Western democracy. And so if you, as an Australian adult, want to exercise your right to gamble and play violent video games, that’s just too bad. The rights of some hypothetical teenager to enjoy freedom from grown-up pursuits trump your own rights to pursue them.

Denmark moves to save its citizens from Marmite

Filed under: Bureaucracy, Europe, Food, Health — Tags: , , — Nicholas @ 07:22

Danish diners will no longer be subject to the horrors of Marmite, thanks to swift and decisive action by the country’s Veterinary and Food Administration:

According to the advert, you either love it or hate it. As far as Marmite goes, the Danish government hates the stuff. That at least is the conclusion that many foreigners have drawn following a ban on the sticky brown yeast extract.

The sales ban enforces a law restricting products fortified with added vitamins. Food giant Kellogg’s withdrew some brands of breakfast cereal from Denmark when the legislation passed in 2004, but until now Marmite had escaped the attention of Danish authorities.

“What am I supposed to put on my toast now?” asked British advertising executive Colin Smith, who has lived in the country for six years. “I still have a bit left in the cupboard, but it’s not going to last long.”

I celebrated the decision by having some Marmite on crackers for lunch yesterday. More for me!

Update: “Let the rise of the Marmite Army begin!”:

“Spread the word, but most importantly spread the Marmite,” wrote Kelly. “On every street in good old Denmark, show ’em what they’re missing after they’ve banned this iconic product from our supermarket shelves! Make it a Marmite day everyday folks! Let the rise of the Marmite army begin!”

But even on the page, opinion remained divided. A perplexed Ray Weaver wrote: “but… it’s horrible…”

On the page calling for a boycott of Danish goods, fan Joe Figg feared the ban could have far-reaching consequences. “This dastardly move could bring about global warming of toast,” he wrote. While Mark Salisbury wrote: “Down with spread fascism!”

“Why does dubious social science keep showing up in medical journals?”

Filed under: Economics, Media, Science — Tags: , , , , — Nicholas @ 10:08

William Easterly and Laura Freschi have determined the decision tree for publishing crappy social science research:

Aid Watch has complained before about shaky social science analysis or shaky numbers published in medical journals, which were then featured in major news stories. We questioned creative data on stillbirths, a study on health aid, and another on maternal mortality.

Just this week, yet another medical journal article got headlines for giving us the number of women raped in the DR Congo (standard headline: a rape a minute). The study applied country-wide a 2007 estimate of the rate of sexual violence in a small sample (of unknown and undiscussed bias). It did this using female population by province and age-cohort — in a country whose last census was in 1984.

We are starting to wonder, why does dubious social science keep showing up in medical journals?

The medical journals may not have as much capacity to catch flaws in social science as in medicine. They may desire to advocate for more action on tragic social problems. The news media understably assume the medical journals ARE vetting the research.

Britain’s entry in the new race to space

Filed under: Britain, Space, Technology — Tags: , , — Nicholas @ 09:12

Jonathan Amos reports on the UK Space Agency (UKSA) long-simmered design/proposal called Skylon:

Skylon has been in development in the UK in various guises for nearly 30 years.

It is an evolution of an idea first pursued by British Aerospace and Rolls Royce in the 1980s.

That concept, known as Hotol, did have technical weaknesses that eventually led the aerospace companies to end their involvement.

But the engineers behind the project continued to refine their thinking and they are now working independently on a much-updated vehicle in a company called Reaction Engines Limited (REL).

Realising the Sabre propulsion system is essential to the success of the project.

The engine would burn hydrogen and oxygen to provide thrust — but in the lower atmosphere this oxygen would be taken directly from the air.

This means the 84m-long spaceplane can fly lighter from the outset with a higher thrust-to-weight ratio, enabling it to make a single leap to orbit, rather than using and dumping propellant stages on the ascent — as is the case with current expendable rockets.

Update: Lewis Page has more on the Skylon project.

President of TEPCO falls on his sword a few months late

Filed under: Environment, Health, Japan, Media, Technology — Tags: , , , , — Nicholas @ 11:04

The president of the Tokyo Electric Power Co. (TEPCO) has resigned:

In a business practice that recalled the ritual seppuku suicides of samurai warriors, the president of Japan’s largest power company resigned Friday to assume responsibility for the world’s worst nuclear disaster since Chernobyl.

At a nationally televised news conference, Masataka Shimizu bowed deeply in an exhibition of remorse and declared, “I am resigning for having shattered public trust about nuclear power and for having caused so many problems and fears for the people.

“I want to take managerial responsibility and bring a symbolic close.”

Whether it’s a hearkening-back to Samurai ethos or not, he should have resigned long ago, as soon as it became clear that the company he headed was doing everything it could to conceal the extent of the actual damage both from the media and from the government.

There is a widespread feeling the government and TEPCO officials did not disclose all they knew during the early days of the crisis and have been less than forthcoming since.

In the first weeks after the earthquake, TEPCO officials received 40,000 complaints a day about the lack of information. Police had to be assigned to guard the company’s offices from anti-nuclear protesters.

This week, TEPCO released documents showing it was dealing with three simultaneous nuclear meltdowns, while reassuring people the fuel rods were safely intact in all the reactors.

“Why did it take two months to get to this point?” demanded a Wednesday editorial in the Nikkei business newspaper.

“Even a rough calculation of conditions inside the reactors would have helped in choosing the best response.”

Public confidence was shaken further when it emerged engineers at Fukushima were so unprepared for the disaster, they had to scavenge flashlights from nearby homes and used car batteries to try to reactivate damaged reactor gauges.

Nobody with an ounce of sense is criticizing the workers at the plant for their reaction to an earthquake that was far in excess of the design for the reactors, or a tsunami that was much higher than anything the designers had foreseen. Shit happens, and it was the daily double of fantastically unlikely natural disasters that struck the plant.

The company, however, deserves more than just a light dusting of shame for the way they appear to have been actively preventing the real state of the plant becoming known to the international nuclear community and the national government. A nuclear disaster is everyone’s business, and there were resources available to TEPCO that they signally failed to draw upon. Saving face is not an acceptable reaction to this kind of catastrophe.

“Brave stuff indeed, mocking a man of God who is clearly a few clowns short of a circus”

Filed under: Environment, Media — Tags: , , — Nicholas @ 13:37

Brendan O’Neill wonders why we are all happy to pour scorn on Christian predictions of the end of the world, yet treat similarly apocalyptic Green claims seriously:

The eccentric Californian preacher Harold Camping, who claims that Jesus will return this Saturday and bring the world as we know it to an end, has been the subject of much Twitter-teasing and ridicule. “The Rapture? If it comes near me this Saturday I’ll kick its arse through its neck”, says Charlie Brooker. “I expect everyone who thinks so-called Judgement Day is on May 21st to support science and reason from the 22nd onwards”, says Professor Brian Cox. Brave stuff indeed, mocking a man of God who is clearly a few clowns short of a circus. But what I want to know is this: why don’t these Camping critics, these alleged challengers of bunkum and defenders of reason, also stand up to the far more mainstream yet equally batty predictions of End Times emanating from the environmentalist lobby?

Perhaps Camping’s real crime is that he has got the date of the Rapture wrong. After all, according to the green writer Andrew Simms’ countdown to doom, which is published monthly in Brooker’s own newspaper the Guardian, we have 67 months left to save the world. Camping you idiot! The world’s not going to end this Saturday – it’s going to end in December 2016!

Of course Simms, who runs the ominous One Hundred Months project, is not so crude as to talk about Apocalypse or Judgement Day or Rapture. No, he simply says: “We have 70 months to save our climate. When the clock stops ticking, we could be beyond our climate’s tipping point, the point of no return.” Which of course is just a more PC, more sciencey, less instantly insane-sounding way of saying exactly what Camping has said: that there is an endpoint to the world, it is arriving soon, and it will involve some judgement of mankind for his sins against God/overuse of carbon. Where Camping says our sinful behaviour has precipitated Saturday’s rapturous showdown, Simms says it is the “global suicide pact” of human greed and nature-wrecking that gives us only another 70 months. Both of them sound mental.

The Freakonomics approach to sexual research

Filed under: Economics, Randomness, Science — Tags: , , , , , — Nicholas @ 11:56

Inspired by the Freakonomics team and their “let the data lead the way” methods, Ogi Ogas and Sai Gaddam talk about their new book A Billion Wicked Thoughts: What the World’s Largest Experiment Reveals About Human Desire:

Since we’ve written a book offering new ideas about a very intimate and politicized subject — sexual desire — you may be wondering about our identities and ideologies. We’re both heterosexual males. Ogi is 40 and half-Latino, Sai is 30 and all Indian. We kicked off our controversial research project with one overriding principle partially inspired by Freakonomics: no agenda, no ideology, just follow the data wherever it leads.

And the data led us to some very strange places. Here are some of our findings: heterosexual men like shemale porn, large-penis porn, and fantasies of their wives sleeping with other men. Gay male sexuality is almost identical to straight male sexuality. Women prefer stories to visuals, though women who do prefer visuals tend to have a higher sex drive, exhibit greater social aggression, and are more comfortable taking risks. Men prefer overweight women to underweight women. Heterosexual women like stories about two masculine men sharing their tender side and having sex. Porn featuring women in their 40s, 50s, and 60s is popular among men both young and old. For women, online erotica is often a social enterprise, while for men it’s almost always a solitary one. Most men are wired to be aroused by sexual dominance and most women are wired to be aroused by sexual submission, though a large minority of straight men (and a majority of gay men) prefer the sexually submissive role, and a small minority of women prefer the sexually dominant role.

They then answer a series of questions posed by Freakonomics readers, some of which are quite hostile in tone.
