Not just my imagination

Let’s just say it: The Republicans are the problem. - The Washington Post

I had missed this article from April, in which, once again, it's pointed out that the Right has gone nutty in the US. 

A few things to keep you going

I'm busy with assorted stuff, but note the following:

*  Exactly as I guessed, it seems more scientist types are saying that making crops RoundUp resistant was and is a bad long term strategy.   It is short term gain for long term pain.  Common sense also suggests that making crops more and more resistant to more and more herbicides is not the healthiest thing for the environment.

*  Some talk about why universes might live inside black holes.

*  Real Climate talks about the paper I already noted regarding climate change and an increase in the water cycle.

*  Real Climate also talks about the Australian temperature reconstruction that shows an Australian "hockey stick"-ish rise in temperatures since about 1950.    

*  Media Watch on the appalling reporting of the "climate scientist death threats" story by the Australia was very good.  Andrew Bolt's attempted response was embarrassing. 

*  One thing that might have been thought to do better with more CO2 in the air, and oceans, was sea grass.  However, those in the Mediterranean are apparently sensitive to increasing warm water, and it might already be dying off in places because of that.   Another loser in the game of winners and losers.

"Summer" movie time

Hey, it's not just me who feels completely "over" superhero films.  Not that I was ever really into them, I suppose.    I unexpected enjoyed Spiderman 3, ever though most people seemed to think emo Parker just meant they couldn't take it seriously.  But really, comic book superheros on screen, from Batman to Superman to Captain America - just call me underwhelmed, generally.

As Charlie Brooker's acerbic column, written after seeing Avengers, notes:

Despite being almost completely incoherent, it's enjoyable bibble, and as good as superhero films are ever likely to get, which is excellent news because it means they can stop making them now. Seriously, they needn't bother releasing Batman Bum Attack or whatever the next one's called, because it won't be as good as Marvel Avengers Assemble 3D. Finally we can move on, as a species. 

Charlie even joins me in blaming spectacle done in the computer as part of the reason:

Finally – and this is an odd accusation to level at a superhero film – it didn't feel very real. I reckon only about 8% of what was on screen was actually there. The rest was imagined by computers. And please, leery tragi-men, don't dribble on about "Scarlett Johansson's arse in 3D" being "worth the price of admission". The film was shot in 2D and converted to 3D using software, which means you're actually drooling over a 2D image of Scarlett Johansson's arse wrapped around a wireframe model of an arse that isn't there.

So, I won't be off to see it.

But, I will be off to see Men in Black 3 next weekend (OK, I know it is originally based on a comic too, but the leads are not superheroes.)  Early reviews are not too bad:  most seem to think it better than 2, which really was not that bad when I watched it again on DVD recently.

I would also hope that Prometheus is good.  The David the Android promo clip is pretty creepily brilliant.

No Spielberg this summer, but you can't have everything.

Very late movie review

I think it was sometime in the last 12 months that I bought and re-watched the original The Day The Earth Stood Still.  It was, to be honest, rather slower than I remembered.  Certainly its most spectacularly anachronistic feature says more about us than aliens:  it was the way the widowed Mum immediately trusts a single male stranger who turns up at home to take her son on an outing in the city.   (Today, she would be arrested by social services for the alien failing to have a Blue Card.)    But still, it's a good film and a classic in serious 1950's moralistic science fiction.

Last night I caught up with the 2008 remake with Keanu Reeves.   As I think some reviewers noted at the time, Keanu does "alien" pretty well.   The film looks pretty good for the most part, and the switch to the aliens being concerned about the planet for environmental reasons rather than nuclear war is a good idea conceptually.    But I have 4 problems with it, which I will put in increasing order of severity:

1.  Kathy Bates as Secretary of Defence?   She just wasn't right for the role.  I kept expecting her to take a sledgehammer to Keanu's ankles for the sake of the planet.

2.  The black stepchild who wanted to blow up the aliens instead of befriending them.  This is rather against the tenor of modern children, isn't it, whether or not they have a dead father who in the military?   Besides, he wasn't a very good actor.

3.  Did it make any sense at all at the start that the government pulls a team of experts together to deal with a mystery, potentially destructive, object heading towards New York, only to put them in helicopters hovering above Manhattan while the unknown object hurtled towards Central Park?  That's a rhetorical question:  no, it made no sense at all.

4.  What happened at the end?   How did Keanu stop the nanobots?  Turned out to be pretty easy for him.  What did the alien clean up team think about this?   Was the Earth going to start again?  (Maybe it did - I was getting sleepy towards the end.)  Did the "ark" spheres still take the critters collected off the planet?  Why? 


It was the worst science fiction ending, in terms of ambiguity, I can remember, at least at the moment.  Just terrible.  This was, by far, the biggest downfall of the movie.

HDL ‘Good Cholesterol’ Found Not to Cut Heart Risk - NYTimes.com

This would upset the apple cart a bit.  Particularly given this:

Researchers not associated with the study, published online Wednesday in The Lancet, found the results compelling and disturbing. Companies are actively developing and testing drugs that raise HDL, although three recent studies of such treatments have failed.

Queensland floods: now with added warming

Soon after the Queensland floods of 2010/11, skeptics were quick to rush out and deny there could be any connection to global warming.

At the time, I thought "That's odd.  I'm sure I read that record sea temperatures - which, call me crazy, but just might have some connection with global warming - was one of the key reasons that led to the weather bureau giving a specific warning to the Queensland government in late 2010 that it was looking like a very high probability of big summer floods."

But there were some voices making a cautious connection between global warming possibly being responsible for making hot La Nina water temperatures even worse than they would otherwise be:

Professor Matthew England, co-director of University of New South Wales Climate Change Research Centre, is reluctant to explicitly apportion any of the flood crisis to climate change. But he stressed that “to exclude climate change would be premature”.

Earlier this week, he told Reuters news agency: “I think people will end up concluding that at least some of the intensity of the monsoon in Queensland can be attributed to climate change. The waters off Australia are the warmest ever measured and those waters provide moisture to the atmosphere for the Queensland and northern Australia monsoon.”

Professor England explained to me the waters to the north of Australia have warmed by about 0.5C over the last 50 years. Those waters are currently about 1.5C warmer than average, he said, so it’s likely that about a third of this warming is due to long-term ocean temperature increases, the remainder due to the normal La Nina cycle.

 (For anyone doubting the extent of the floods that came, and the high sea temperatures around Northern Australia that preceded it, you should have a look through the slides the BOM used at the flood enquiry earlier this year.)

And now, we have the first paper that does some detailed analysis.  The bottom line, as reported in the Sydney Morning Herald is this estimate:

 A Sydney researcher, Jason Evans, ran a series of climate models and found above average sea surface temperatures throughout December 2010 increased the amount of rainfall across the state by 25 per cent on average....

Between December 23 and 28 many places experienced up to 400 millimetres of rain in a few days. "That [means] 100 millimetres of rain was attributable to sea surface temperatures," said Dr Evans, a future fellow at the University of NSW's Climate Change Research Centre.

While the flooding occurred during one of the strongest La Nina events on record it was insufficient to produce the extreme rainfall recorded, he said.

The effect of the high sea surface temperatures coupled with the impact of a La Nina, both of which are associated with above average rainfall over eastern Australia, plus tropical cyclone Tasha, combined to create an extreme weather event, he said.

The resulting floods stretched across 1.3 million square kilometres all the way to Brisbane, caused billions of dollars in damage and killed 35 people.

Now, the study does not actually look at what caused the high temperatures, and as such you can't really call it an attribution study relating specifically to the role of AGW.   (I suppose it's like the first half an attribution study - first look at whether warmer waters did contribute to increased flooding, then look at how the water got warmer.)    Still, surely it's reasonable to strongly suspect, seeing the gradual rise in the relevant sea surface temperatures over the last 30 years, that AGW might just have something to do with it.  From the university press release:

And this:

Sea-surface temperatures off northern Australia in the Indian Ocean, Arafura Sea and Coral Sea  were unusually warm at the time, in places as much as 2 degrees C, the study notes: analysing 30 years of historic measurements, the study identified a general warming trend there of at least 0.2 degrees C per decade.

“If the observed warming trend in the sea-surface temperatures continues, this result suggests that future La Niña events are more likely to produce extreme precipitation and flooding than is present in the historical record,” says Dr Jason Evans, of the UNSW Climate Change Research Centre. Dr Evans led the study, to be published in the journal Geophysical Research Letters, with a French co-author, Dr Irène Boyer-Souchet.

A few posts back, I noted that some studies indicate a substantial warming of nearly 3 degrees in parts of the Pacific by the end of the Century.

Here's the thing:  if sea temperature rises that are already being observed can make floods substantially worse, what's the situation going to be like in 50 - 100 years with another 2 - 3 degree increase?

And what's the best the climate "fake skeptic" world can come up with in response to this?  Well, seeing the study doesn't look at what caused the high temperature water:

"abnormally high ocean temperatures" may have simply been natural variability at work. But according to England, climate change "could not be excluded". Similarly, therefore, we cannot exclude the possibility that the Flying Spaghetti Monster was behind it, sneakily raising sea temperatures with his noodly appendage…

It's a really pathetic and lame attempt to turn around (what I would say) is an overly cautious choice of words into an attempted bit of logical ridicule.  

As for those who argue for adaptation to climate change as opposed to seeking serious reduction to greenhouse gases:  tell me how well you think Queensland can adapt to a potential increased severity (and frequency?) of floods affecting a million or so square kilometres? 

My hunch formed during 2010 - 2011 that increased intensity of floods was soon going to be recognised as one of the most serious aspects of AGW is still probably right, I reckon.

Wes returns

I wouldn't say I'm the world's biggest Wes Anderson fan, but I really liked Fantastic Mr Fox.  I see that he has a new film out soon, with Bill Murray (again), Bruce Willis (!) and Tilda Swinton (!!), and it looks very eccentric indeed:

 

UPDATE: Surprise! It's getting good reviews.

Cat attack on your eyes

New funding for research on parasitic eye disease

People who read about science over the last few years would have heard about toxoplasma gondii (which you can catch from your cat's litter box, amongst other places) and its odd behavioural effects on rats and (possibly) humans.  I don't recall reading about this before, though:

Brooke Anderson-White, PhD, a postdoctoral scholar in pathology, has received a grant from the Knights Templar Eye Foundation Inc. for research to develop vitally needed new treatments for severe eye infections caused by the Toxoplasma gondii parasite.

The parasite infects as many as a billion people worldwide, many of whom have no symptoms. However, it can cause severe problems in those with weakened immune systems or in infants infected during pregnancy, leading to the condition toxoplasmic retinochoroiditis. Infected children can develop severe vision impairment and blindness as a result of retinal scarring caused by the disease. Toxoplasmic retinochoroiditis is a major source of visual impairment in the United States.

Not sure what it means

Once again, there is talk from scientists about whether a quantum wave function is itself  "real".

I'm not sure of the importance of the debate.   The brief discussion of it at the link above suggests it helps solve the Schrödinger’s cat thought experiment, and as we all like our pets to be either dead or alive (not in a fuzzy in between state) that could be a useful outcome.

Anyway, I need some better explanation of this...

Carbonara considered (more than you thought possible)

Steganography appears again

Al Qaeda suspect's porn film found to contain treasure trove of secret documents

Once again, the topic of steganogaphy (software that secretly hides information within what appears to be ordinary media files) being used by real life terrorists is in the news.  My interest in this is just an adult version of an interest in invisible ink, I guess, but we can all have our fun imagining being a spy (not so much a terrorist):

The researchers from the German Federal Criminal Police (BKA), spent many weeks examining the hidden pornographic video* found on suspected Al Qaeda member, the Austrian Maqsood Lodin, when he was arrested in Berlin after returning from Pakistan. The video, called “Kick Ass,” was stored in a password-protected folder and within the video they found a file called “Sexy Tanja.” Further analysis of this file eventually revealed that it contained more than 100 concealed unencrypted documents describing Al Qaeda plans and operations.

A video file has ample room for concealing documents, and would be relatively easy to distribute. In Maqsood Lodin’s memory stick, the porn video contained hidden terrorist training manuals in pdf form in English, German and Arabic, along with numerous documents detailing planned future Al Qaeda attacks, and lessons learned from previous operations.

Minimizing grid use

Novel battery system could reduce buildings' electric bills

I don't know what to make of this, but in some places (like all of Australia from about Sydney up), it's easy to imagine that domestic large scale batteries to store excess electricity generated by solar panels during the day could mean a house uses very little electricity off the grid.  If, say, an extra $10,000 on a new house build could give a very large saving on electricity use both during the day and night, would it make more sense to do that rather than having solar panels that feed back into the grid?  It would at least avoid the problems to the grid that feed in solar panels can cause.

Discouraging ocean predictions

Equatorial refuge amid tropical warming

From the link:

Upwelling across the tropical Pacific Ocean is projected to weaken in accordance with a reduction of the atmospheric overturning circulation¹, enhancing the increase in sea surface temperature relative to other regions in response to greenhouse-gas forcing. In the central Pacific, home to one of the largest marine protected areas and fishery regions in the global tropics, sea surface temperatures are projected to increase by 2.8 °C by the end of this century^{2, 3, 4}. Of critical concern is that marine protected areas may not provide refuge from the anticipated rate of large-scale warming, which could exceed the evolutionary capacity of coral and their symbionts to adapt⁵.

I am, like George Costanza, no marine biologist, but that does sound like a heck of an increase in sea surfaces temperatures in waters that are already pretty warm.

The article goes on to explain that there might be some compensating upwelling which will cool certain Pacific Islands, but even so the temperatures will be up.  Just not as much.

Sounds like a hot time for many coral reefs.

In another article in Nature Climate Change, some researchers think that increased CO2 will hurt, not help,  phytoplankton, contrary to what you might expect:

Carbon dioxide and light are two major prerequisites of photosynthesis. Rising CO₂ levels in oceanic surface waters in combination with ample light supply are therefore often considered stimulatory to marine primary production^{1, 2, 3}. Here we show that the combination of an increase in both CO₂ and light exposure negatively impacts photosynthesis and growth of marine primary producers. When exposed to CO₂ concentrations projected for the end of this century⁴, natural phytoplankton assemblages of the South China Sea responded with decreased primary production and increased light stress at light intensities representative of the upper surface layer. The phytoplankton community shifted away from diatoms, the dominant phytoplankton group during our field campaigns.

 So how does the increased light happen in future?  This seems to be explained in the last part of the abstract:

Future shoaling of upper-mixed-layer depths will expose phytoplankton to increased mean light intensities⁵. In combination with rising CO₂ levels, this may cause a widespread decline in marine primary production and a community shift away from diatoms, the main algal group that supports higher trophic levels and carbon export in the ocean.

Well, there you go.  More news of the giant climatological and ecological experiment that is underway, and that serious people should take seriously.  

Extremes

BBC News - Gaia creator rows back on climate

Climate change deniers (as they have adopted "alarmists" and "warmenists" as a matter of routine, I'm not going to worry about using "denier" any more, although I have a soft spot for "fake skeptics") were all excited about Lovelock's recent interview where he said he had been too alarmist in his previous talk about how climate change would only leave a handful of breeding humans in the Arctic, and that "no one knows" what the climate is doing.   

As I tried to tell the selectively stupid at another blog, it's not as if Lovelock was ever "mainstream" on the topic.  My sentiments were summarised by a climate scientist quoted at the BBC (link at the top):

 One IPCC scientist, who said he didn't want to be drawn into a personal argument with Dr Lovelock, said: "Jim exaggerated the certainties of climate change before, which wasn't helpful then. His recent comments aren't helpful now

"They will be seized on by people who argue that science is too uncertain to inform policy - and that's absolutely not the case. He's blown too hot, now he's blowing too cold."

Prof Hans von Storch of the Meteorological Institute at the University of Hamburg told BBC News: "Lovelock certainly exaggerated in 2006. It seems that the extreme position on both sides are losing ground, and that is good."

James Annan is also happy to point out that he and others called out Lovelock's extreme pessimism at the time, including Tim Lambert in Australia.

That said, nearly everyone still likes listening to Lovelock.   He is a very interesting character with lots of good work behind him.  It's just that he has been well out on his own in terms of pessimism on climate change.

But does this wash with the selectively stupid will take his current view as indicating that everything is so uncertain that nothing should be done about CO2 emissions?  No, of course not.

Dream knowledge

Shortly before I woke up, I was having a dream which was set in a sort of fantasy RNA Show (the Ekka, if you're from Brisbane.)  I think it was Dick Smith who was walking around with me.   (Don't ask me why - apart from the fact he was recently on some TV promo for a current affairs program giving away money to people.)

It ended up at a table where Bob Geldorf and, I think, some other famous person, were drinking with Dick Smith and me.  There were nuts on the table being eaten as a snack (I remember walnuts in particular - toasted walnuts are perhaps my favourite nut) and Bob made the comment that he used to lead an unhealthy lifestyle in which the only thing he ate was nuts.  I asked whether he knew that peanuts were not actually a nut.   Then the person sitting next to Geldorf said "that's right, they're a legume."

When I woke up, I couldn't quite recall whether that was right (the bit about being a legume, I mean.)  The Peanut Institute confirms it is.

Some people dream of winning lottery numbers, or solve scientific puzzles.  My subconscious is quite a bit more useless.

The dangerous tub

The Japan Times has an editorial on an unusual topic:

An investigation into one of Japan's favorite pastimes — bathing — has found a startling statistic: 14,000 people a year die during bath time. That's nearly three times more deaths than from car accidents, 4,612 people....

Bathing seems such a comforting and pleasant activity that it is hard to associate it with danger. However, the deaths come from several different problems. Some deaths resulted from drowning when bathers fell asleep. Other causes were heart attacks, subarachnoid hemorrhages or strokes from the sudden shift in temperatures. Dehydration and injuries resulting from slipping were also among the causes.

Researchers at Kyoto Prefectural University of Medicine found last year that the danger of heart attacks is nearly 10 times greater in winter than in summer — and much higher than the risk of cardiac arrest during exercise. The rapid blood pressure drop that happens when getting in the bath stresses the heart more on a cold day, which can lead to a number of complications.

An interesting analysis

We need to talk about energy, not rates - The Drum (Australian Broadcasting Corporation)

Alan Kohler is upset that badly needed investment in electricity in Australia is being stalled due to uncertainty, caused in large part by the Tony Abbott "must revoke the carbon tax" policy.

I'm sure Kohler is not alone in this view.   But where are the economists who feel this way?   Are they just going to sit on their hands, or wait until an election is looming and then say that dismantling the governments carbon pricing scheme, and replacing it with Abbott's second rate "direct action" really doesn't make sense?

Anyway, here is Kohler's depressing conclusion:

If they're all thrown out, as promised, then the new minister will have to start the process all over again. By the way, the shadow minister is Ian Macfarlane, who came within a bee's willy of negotiating an emissions trading scheme in 2009 with the then minister, Penny Wong.

Presumably he no longer believes in that crazy stuff.

Anyway, aside from whatever carbon abatement costs are imposed by either political party (they both have the same reduction target of 5 per cent by 2020), electricity prices are already set to double by 2017 because of chronic under-investment in east coast transmission and distribution over previous decades.

This price increase cannot be avoided – it is already locked in. In fact, it will be greater than that if the 20 per cent renewable energy target is to be met because renewable generation is always further away, so that transmission costs more.

The only antidote to the huge, looming increase in the price of electricity, not to mention the possibility of brownouts caused by the lack of investment in base load power, including nuclear, is energy efficiency.

Unless urgent action is taken, the rising price of power will destroy manufacturing and retail businesses far more effectively than the internet and the currency, which has a tendency to go down as well as up.

Japanese tornado

God really seems to have it in for Japan at the moment. 

A compilation video of yesterday's tornado, looking very much like footage we more commonly see from the middle of America, can be see here.

Of course, people interested in climate change will be curious as to how rare this is.  As the Wikipedia knows all, it indicates that tornadoes are indeed pretty rare, but not unknown, in Japan.  Other odd places that have had tornadoes on that list include Moscow in 1904.  I guess that wherever you can get a storm, a tornado may be possible.

Good movies

First, Addams Family Values. The original Addams Family movie was on TV a couple of weeks ago, and went over well with the kids, so I went looking for the second at the DVD rental place. (Does everyone feel a bit of melancholy like I do for this slowly dying line of business which will probably be gone completely in 5 years?)

Both Addams Family movies are based almost entirely on the funny one-liner, but so many of them are terrific. I think the best from the second movie would have to be when Joan Cusack, playing Uncle Fester's conniving love interest, says "Isn't he a ladykiller", to get the cheery response from Gomez "Acquitted!"

Watching these movies made me realize how much I like the sense of humour of director Barry Sonnenfeld. He did the Men in Black movies too, and has a third one coming out soon. I will be there early unless it has catastrophic reviews: even though the second MIB was not thought of highly by many, and I found it to be better than I remembered when I re-watched it recently.

Second movie from yesterday: Charade. I'm not sure, but I think I had only seen this once, as a teenager on TV. I remembered liking it very much, but only recalled a rooftop fight and the ending. Re-watching it 30 something years later therefore was a relatively fresh experience, and I have to say, the only wonder is why it isn't more often talked about as the classic bit of entertainment it truly is. In my books, it was Audrey Hepburn at her peak: a screen presence who (as we all know) was impossible to dislike in anything. But give her a script full of funny one-liners, and a role that let her do her vulnerable/playfully assertive act with Cary Grant as her love interest: well, what can go wrong? (Don't worry, nothing does.).

For those who don't know, it is like a funnier Hitchcock movie, and set in Paris in the early 1960's.  (JFK's photo is seen on the wall of the US Embassy, and the movie was released just a couple of weeks after his assassination.  I wonder if that unfortunate timing, when I imagine lots of Americans were too shell shocked to be seeking out lightweight entertainment, partly accounts for it not being as well known as it deserves.)  

 I see that Jonathan Demme did a remake which I have never heard of: why does anyone ever think it a good idea to remake movies which worked fantastically well in their first incarnation?

Anyway, a good viewing day was had by all.

Liking hospitals

I've been at hospitals on and off a fair bit in the last few years, but never for anything too dramatic - it's just what happens when you have kids and an elderly mother.  Getting my Mum to one over the last few days is why I haven't been posting much.

It almost feels like this is something that one shouldn't say - but I really like hospitals.   I like them architecturally - the way they grow and expand, usually with walkways joining different wings and buildings.  (Doesn't everyone like elevated walkways?)   I think being an architect working on a hospital re-vamp must be one of the most interesting jobs around.  I like the challenge of finding your way around these complexes. I like the way beds get pushed around and up and down different floors. 

I like buildings with helipads and red flashing lights on the roof.   I like high technology of all types, and x ray and medical imaging technology is some of the fanciest and cleverest stuff you are ever likely to see.

I usually like the staff:  working odd hours, usually with good cheer.  I like how hospitals are much more convenient places than they used to be - the car parks are usually not too expensive; there may be a Starbucks in the foyer, or a sushi place just outside, even in public hospitals.    During the day they'll probably be a volunteer at a desk to help find you something.  

I don't really care for waiting for 5 hours to see a doctor, but hey, it's a free service and I don't feel I can complain too much as long as the person I am with is not in pain.  Besides, waiting there is a bit like a free drama show - trying to overhear what the drug addicted or mentally ill person is complaining about at the admissions counter, or wondering what sort of illness the guy clutching his abdomen might be suffering.  It also gives me the opportunity to understand how boring and regrettably enduring is reality TV, because I will not sit at home to watch 4 couples arguing with each other about their designs and accidents while doing a renovation of a row of old terrace houses. 

I'm not sure how many people feel this way.  The Yahoo Questions page asking "Is it strange that I like hospitals"  has few responses.  Hospital fans need their own support group, perhaps.  I'm here to help.

Something you've never thought about before

YKK zippers: Why so many designers use them. - Slate Magazine

Exactly

What an excellent bit of video which was not shown on the ABC's fairly forgettable climate change documentary last week "I can change your mind about climate."



I think Nick Minchin (the skeptic ex-politician), obviously liked Anna Rose (the young climate change "believer"), so much so that by the end he tried to come up with a compromise, along the lines of saying that as all fossil fuel sources are finite, he could support a move towards renewable energy now.

It's a pity this position doesn't make much sense, as far as doing anything about emissions - especially in Australia, where we have enough coal to burn for hundreds of years.   There is no urgent imperative to implement clean electricity at all out of concern for running out of dirty ways to make it.  (The argument might have a chance of working if it restricted to finding a way to make good electric cars, given oil will presumably start running out sooner than coal.)

As someone wrote about Minchin:

In all, five of Minchin’s seven experts appeared in the documentary, but only three of Rose’s. While this might sound unfair to Rose, I think that Minchin’s experts did more harm to his cause than good.

That said, I was concerned to read Minchin being quoted in the Sydney Morning Herald yesterday as saying that the documentary was a “terrific opportunity to convey to an ABC audience that there remains a significant debate”. If Minchin had any insight he would realise that the documentary simply exposes his gullibility.

 Quite true, I think, and all the more galling that the documentary left out the video above.

Sounds like an important paper

From Science:

Fundamental thermodynamics and climate models suggest that dry regions will become drier and wet regions will become wetter in response to warming. Efforts to detect this long-term response in sparse surface observations of rainfall and evaporation remain ambiguous. We show that ocean salinity patterns express an identifiable fingerprint of an intensifying water cycle. Our 50-year observed global surface salinity changes, combined with changes from global climate models, present robust evidence of an intensified global water cycle at a rate of 8 ± 5% per degree of surface warming. This rate is double the response projected by current-generation climate models and suggests that a substantial (16 to 24%) intensification of the global water cycle will occur in a future 2° to 3° warmer world.

More Beard

Lucky me. Here's another, meatier, bit of writing by Mary Beard. She's reviewing a new book about Caligula.

While he was undoubtedly a terrible man, Beard notes that some of the stories about him are not quite what they seem. In fact, the worst thing he did in I Claudius (the TV series of which I have only seen, once, when it was first run on TV in the 1970's) was completely invented:

Much more shocking was the portrayal of Caligula in BBC Television’s 1976 adaptation of I, Claudius. In his novels, Robert Graves had exploited the ancient allegations that Caligula had a suspiciously close relationship with his sister Drusilla. The inventive Jack Pulman, author of the screenplay, went even further. In a terrifying scene that has no source either in ancient accounts or in Graves’s narrative, he has Caligula (John Hurt) take on the guise of Jupiter and cut the baby Drusilla is carrying from her belly and – on the model of some versions of divine gestation and paternity in Greco-Roman myth – eat the foetus. The ‘Caesarian’ itself was not shown on screen, but Caligula’s very bloody mouth was. Deemed too much for American audiences, the scene was cut out of the PBS version of the series.

Odd how we got the full scene on the ABC, but the Americans didn't.

Anyhow, there is lots more good stuff in the review, and as usual, Beard is a good read.

Revelation considered

A witty and informative review by Adam Gopnik in the New Yorker about a new book by Elaine Pagels on the Book of Revelation can be found here.

In my experience, Revelation has not been paid much attention in Catholic education or liturgy.  I think most see it as a bit of an oddball book full of obscure references and not really worth trying to decode in full.   Protestant evangelicals, on the other hand, do treat it as a big Hollywood movie, as Gopnik amusingly compares it to in his opening paragraphs:

That ending—the Book of Revelation—has every element that Michael Bay could want: dragons, seven-headed sea beasts, double-horned land beasts, huge C.G.I.-style battles involving hundreds of thousands of angels and demons, and even, in Jezebel the temptress, a part for Megan Fox. (“And I gave her space to repent of her fornication; and she repented not.”) Although Revelation got into the canonical Bible only by the skin of its teeth—it did poorly in previews, and was buried by the Apostolic suits until one key exec favored its release—it has always been a pop hit. Everybody reads Revelation; everybody gets excited about it; and generations of readers have insisted that it might even be telling the truth about what’s coming for Christmas.

Gopnik notes the unoriginal part of Pagel's book:

Pagels then shows that Revelation, far from being meant as a hallucinatory prophecy, is actually a coded account of events that were happening at the time John was writing. It’s essentially a political cartoon about the crisis in the Jesus movement in the late first century, with Jerusalem fallen and the Temple destroyed and the Saviour, despite his promises, still not back.

but goes on to point to the more novel argument put by her:

 Revelation is essentially an anti-Christian polemic. That is, it was written by an expatriate follower of Jesus who wanted the movement to remain within an entirely Jewish context, as opposed to the “Christianity” just then being invented by St. Paul, who welcomed uncircumcised and trayf-eating Gentiles into the sect. At a time when no one quite called himself “Christian,” in the modern sense, John is prophesying what would happen if people did. That’s the forward-looking worry in the book. “In retrospect, we can see that John stood on the cusp of an enormous change—one that eventually would transform the entire movement from a Jewish messianic sect into ‘Christianity,’ a new religion flooded with Gentiles,” Pagels writes. “But since this had not yet happened—not, at least, among the groups John addressed in Asia Minor—he took his stand as a Jewish prophet charged to keep God’s people holy, unpolluted by Roman culture. So, John says, Jesus twice warns his followers in Asia Minor to beware of ‘blasphemers’ among them, ‘who say they are Jews, and are not.’ They are, he says, a ‘synagogue of Satan.’ ” Balaam and Jezebel, named as satanic prophets in Revelation, are, in this view, caricatures of “Pauline” Christians, who blithely violated Jewish food and sexual laws while still claiming to be followers of the good rabbi Yeshua. Jezebel, in particular—the name that John assigns her is that of an infamous Canaanite queen, but she’s seen preaching in the nearby town of Thyatira—suggests the women evangelists who were central to Paul’s version of the movement and anathema to a pious Jew like John. (“When John accuses ‘Balaam’ and ‘Jezebel’ of inducing people to ‘eat food sacrificed to idols and practice fornication,’ he might have in mind anything from tolerating people who engage in incest to Jews who become sexually involved with Gentiles or, worse, who marry them,” Pagels notes.) The scarlet whores and mad beasts in Revelation are the Gentile followers of Paul—and so, in a neat irony, the spiritual ancestors of today’s Protestant evangelicals.

 All interesting stuff.

 

But, as a long time fan and promoter of the importance of gnostic writings (perhaps too much so), Pagel's book apparently goes on to talk about them, again, in the context of the times.  Gopnik quotes a "feminist" poem found at Nag Hammadi with this very funny line:

As an alternative revelation to John’s, she focusses on what must be the single most astonishing text of its time, the long feminist poem found at Nag Hammadi in 1945 and called “Thunder, Perfect Mind”—a poem so contemporary in feeling that one would swear it had been written by Ntozake Shange in a feminist collective in the nineteen-seventies, and then adapted as a Helen Reddy song.

As to how the book got into the Bible at all:

Pagels’s essential point is convincing and instructive: there were revelations all over Asia Minor and the Holy Land; John’s was just one of many, and we should read it as such. How is it, then, that this strange one became canonic, while those other, to us more appealing ones had to be buried in the desert for safekeeping, lest they be destroyed as heretical? Revelation very nearly did not make the cut. In the early second century, a majority of bishops in Asia Minor voted to condemn the text as blasphemous. It was only in the three-sixties that the church council, under the control of the fiery Athanasius, inserted Revelation as the climax of the entire New Testament. As a belligerent controversialist himself, Pagels suggests, Athanasius liked its belligerently controversial qualities. “Athanasius reinterpreted John’s vision of cosmic war to apply to the battle that he himself fought for more than forty-five years—the battle to establish what he regarded as ‘orthodox Christianity’ against heresy,” she writes.

That's probably about as much as I should fairly quote.  Go read the whole thing: it's great.

Credibility down

Roy Spencer, man of mystery | Open Mind

Roy Spencer, the satellite temperature lukewarmer climate scientist, has been fiddling with figures from the US Historical Climate Network (which is supposed to be accurate) and speculates that urban heat island type effects accounts for nearly all of recent US temperature increase.

As Tamino points out, this doesn't make sense when you consider Spencer's own satellite work contradicts this.

Spencer is firmly amongst the "skeptic" group that just spends all day speculating that something, anything, must be able to explain that temperature rises from increased CO2 will not be dangerous.

Believing, more or less

Belief in God strongest in US and Catholic countries, surveys find

According to this research looking at changes in belief in God internationally since 1991,  theism is gradually declining, but is increasing in a few places such as Russia, Slovenia and Israel.  (The last one is a bit of a surprise.  Maybe the Holocaust took its toll in that respect.)

But in an international survey that did not include China, one surely couldn't place too much  faith in the accuracy of the estimates.

The most curious part of the research is perhaps this:

Belief is highest among older adults. On average, 43 percent of those aged 68 and older are certain that God exists, compared with 23 percent of those 27 and younger, according to the report.

"Looking at differences among age groups, the largest increases in belief in God most often occur among those 58 years of age and older. This suggests that belief in God is especially likely to increase among the oldest groups, perhaps in response to the increasing anticipation of mortality," Smith said.

He noted that the higher level of belief was not simply a cohort effect, in which people carry forward attitudes shaped in younger years.

In the United States, for instance, 54 percent of people younger than 28 said they were certain of God's existence, compared with 66 percent of the people 68 and older.

In countries with low overall belief in God, the difference in belief between age groups is also strong. In France, for example, 8 percent of younger people said they were certain that God exists, compared with 26 percent of the people 68 and older. In Austria, 8 percent of the younger generation said they were certain in their belief, while 32 percent of people 68 and older were confident of God's existence.

I'm not sure if this is somehow related to decreasing belief in global warming amongst older people, which has often shown up in surveys. (I have long been maintaining that such denial is, essentially, a matter of faith in its own way.) It's worth remembering, though, in the US at least, all ages in the Evangelical churches are prominent disbelievers in AGW. On the other hand, I'm pretty sure Catholics in any country are more likely to not dispute it.

Someone else will have to work out what this all means.

Hopeless

A remarkable and sad article here on the incredibly high rate of suicide in aboriginal communities in the Kimberley region. Alcohol abuse, and (it seems) a sort of cultural hopelessness is at the heart of the problem, making it very hard to address adequately.

The not so secret life of Richard?

So, here's how it goes. A not very interesting article found via Arts and Letters Daily about Walt Whitman leads me to a page full of links to essays by a homosexual academic and author which are, actually, pretty interesting about the history of this activity, particularly in England; particularly in the Georgian period. Have a look at this page where he lists many primary sources about the situation in the 18th century London. I saw a bit of documentary on SBS about the somewhat strange "Molly" gay culture in England at the time, but this website provides a lot of detail.

With all the disproportionate media attention that is given to gay marriage and rights these days, it's odd to realise that even three hundred years ago in London, I might have still been cursing that the local paper was carrying on so much about the topic, albeit from a very different perspective.

I don't believe everything Norton says on the whole subject; as with other gay academics, he seems inordinately keen to claim anyone in history as homosexual. But somewhere in there he notes Richard the Lionheart as been suspected of having a relationship with (at least) King Philip II of France. I think I had seen this article in the Guardian a couple of years ago, but noted that some historians were keen to explain that the idea of two blokes sharing a bed back then, even if they later talked about how much they liked each other, didn't necessarily mean sexual contact of any kind had taken place. (And, in fact, if it was just one overnight bedsharing visit - a point I'm not entirely clear on - it does seem unlikely.)

Fair enough, but when I Google the topic of Richard, this link comes up. From a Jesuit university. And it notes that the contemporary chronicler Roger of Hovedon wrote, apart from the short passage usually quoted about Richard and Philip sharing a bed and plate and really, really liking each other's company, another story about Richard which seems to directly record that Richard did not have a problem with "illicit intercourse":

In the same year, there came a hermit to king Richard, and, preaching the words of eternal salvation to him, said: "Be thou mindful of the destruction of Sodom, and abstain from what is unlawful; for if thou dost not, a vengeance worthy of God shall overtake thee". The king, however, intent upon the things of this world, and not those that are of God, was not able so readily to withdraw his mind from what was unlawful, unless a revelation should come to him from above or he should behold a sign. For he despised the person of his advisor, not understanding that sometimes the Lord reveals to babes the things that are hidden from the wise; for the lepers announced the good tidings to Samaria [2 Kings 7], and the ass of Balaam recalled its master from the unlawful way. Wherefore, the hermit, leaving the king, went his way, and hid himself from before his face. In the process of time, however, although the before-named king despised the admonitions of the poor hermit, still, by inspiration of Divine grace, he retained some part of his warning in his memory, having faith in the Lord, that He who recalled the publicans and the Canaanitish woman to repentance, in his great mercy would give to him a penitent heart.

Hence it was, that on the Lord's day in Easter when the Lord visited him with a rod of iron, not that he might bruise him, but that he might receive the scourging to his advantage. For on that day the Lord scourged him with a severe attack of illness, so that calling before him religious men, he was not ashamed to confess the guiltiness of his life, and after receiving absolution, took back his wife, whom for along time he had not known, and putting away all illicit intercourse, he remained constant to his wife and the two become one flesh and Lord gave him health of both body and soul…"

It's hard to read that any other way, isn't it? Unless one assumes he liked "illicit intercourse" only with women other than his wife. That seems a bit unlikely when the hermit's warning was specifically about sodomy, though. (In fact, had someone close to the king arranged the visit to encourage him to stop embarrassing behaviour, I wonder.)

As I see now from the Wikipedia entry on Richard notes that the "gay" theory only started in 1948, and summarises the situation as follows:

Victorian and Edwardian historians had rarely addressed this question, but in 1948 historian John Harvey challenged what he perceived as "the conspiracy of silence" surrounding Richard's homosexuality.^[102] This argument drew primarily on available chronicler accounts of Richard's behaviour, chronicler records of Richard's two public confessions and penitences, and Richard's childless marriage.^[103] This material is complicated by accounts of Richard having had at least one illegitimate child (Philip of Cognac), and allegations that Richard had sexual relations with local women during his campaigns.^[104]

Leading historians remain divided on the question of Richard's sexuality.^[105] Harvey's argument has gained considerable support;^[106] However, this view has been disputed by other historians, most notably John Gillingham.^[107] Drawing on other chronicler accounts, he argues that Richard was probably heterosexual.^[108]

Historian Jean Flori states that contemporary historians quite generally accept that Richard was homosexual.^[106][109] Flori also analysed contemporaneous accounts; he refuted Gillingham's arguments and concluded that Richard's two public confessions and penitences (in 1191 and 1195) must have referred to the "sin of sodomy".^[110] Flori cites contemporaneous accounts of Richard taking women by force^[111] and concludes that Richard was probably bisexual.^[112]

Flori and Gillingham agree that the contemporaneous accounts do not support the allegation that Richard had a homosexual relation with King Philip II of France, as suggested by some modern authors.^[113]

So, there is more to this than I thought, and I find it rather odd to think that such a figure, more commonly thought of now for gallivanting around Europe on a Crusade, and turning up unexpectedly at the end of Robin Hood movies, was actually the subject of much speculation as to his sex life at the time.

Well, I found it interesting, anyway.

A minor lunar mystery

Scientists suggest evidence of recent lunar volcanism

The article notes:

A team of researchers at India’s Physical Research Laboratory (PRL) claims it has found evidence of relatively recent volcanic activity on the Moon, using data from NASA’s Lunar Reconnaissance Orbiter and the Chadrayaan-1 spacecraft. According to the findings the central peak of Tycho crater contains features that are volcanic in origin, indicating that the Moon was geologically active during the crater’s formation 110 million years ago.

But the more interesting bit:

In addition, large boulders ranging in size from 33 meters to hundreds of yards across have been spotted on Tycho’s central peaks by LRO, including one 400-foot (120-meter) -wide specimen nestled atop the highest summit. How did such large boulders get there and what are they made of?

The researchers hint that they may also be volcanic in origin.

“A surprise findings revealed the presence of large boulders–about 100 meter in size –on top of the peak. Nobody knew how did they reach the top,” said Prakash Chauhan, a PRL scientist.

Beard reappears

BBC News - The 'pushy parent' syndrome in ancient Rome

Mary Beard, the Professor of Classics whose blog at The Times used to be good value (I assume it is behind the paywall now) makes a welcome appearance at the BBC, talking about Roman families.  This bit about the useless nature of ancient doctors caught my attention:

There was no such thing in the ancient world as reliable family planning.

 Roman doctors recommended having sex in the middle of the woman's menstrual cycle if you wanted to avoid pregnancy (as we now know, precisely the time when you are most likely to get pregnant). Not to mention the range of almost completely useless contraceptive creams and potions they peddled.

The fact is there must have been vast numbers of unwanted babies. Many of them would have been literally thrown away - left out on a rubbish dump to be "rescued" maybe by a passer-by and turned into a slave.

Calculating your family size was made even more complicated by the terrifying rates of child mortality before modern medicine. In ancient Rome roughly half the kids born would have been dead by the time they were 10.

Three pieces of Slate

Three stories from Slate last week:

* Yay! A complaint about Word leads to hundreds of comments, amongst which, if you go down far enough, are ones by the hidden secret devotees (and users) of Wordperfect. This is a secret cabal to which I belong too; although I must say that I have found the latest version of Word to be much better than earlier versions for some things.

Many people in that thread mention the wonders of Reveal Codes - a Wordperfect feature that does often let you work out a formatting issue, and which Word has never implemented.

I am often amazed when I have had young people out of university, and who have never known anything other than Word, still can't solve some formatting mystery problem in the program that I assumed I couldn't fix simply due to lack of familiarity.

Long may Wordperfect live (it's still updated every 2nd year or so, you know.)

* A complaint about tattoos also makes claims close to my heart (and is rather brave. Mentioning strong dislike of this trend is usually met with some very rabid insults about how us clean skins just don't understand.)

But what is most interesting is that part - a link to an article about research on the possible health consequences of some of the stuff in tattoo inks. I mentioned this before here. Doesn't sound so hot.

* American teenage birthrate is down, and it seems due to increased use of contraception.

I put it down to the decline of the influence of Sex and the City too. Maybe the second movie was so bad that it convinced teenagers who saw it that the show never got sex and relationships right.

Digital cinema and what it means

Movie Studios Are Forcing Hollywood to Abandon 35mm Film. But the Consequences of Going Digital Are Vast, and Troubling 

A few months ago when I went to one of the big, refurbished, cinema complexes (which I usually avoid in favour of cheaper venues), it looked to me as if they must have gotten into digital projection.  The bright looking result looked pretty good to me, and I assumed that it must indicate that Australian cinemas were finally following the US trend I had been seen mentioned on the 'net over the last couple of years.

The big attraction for studios is that digital distribution saves an enormous amount of money in printing copies of movies on film and couriering them all over the country.

Yet, I had also read that Spielberg (amongst other directors) does not want to shoot on digital cameras.  His films are still shot on film and then converted to digital format.   But increasing, I think,  films (especially special effects heavy ones) are made with digital cameras too.

Anyway, the changes this all means to the movie making business are all set out in interesting detail in the above article.

One of the most surprising things is that, as with computer file format wars generally, the movie industry doesn't have its act together on this yet:

 And even after the films are converted to digital, Jan-Christopher Horak, director of the UCLA Film & Television Archive, calls the challenges of preserving them "monumental." Digital is lousy for long-term storage.

The main problem is format obsolescence. File formats can go obsolete in a matter of months. On this subject, Horak's every sentence requires an exclamation mark. "In the last 10 years of digitality, we've gone through 20 formats!" he says. "Every 18 months we're getting a new format!"

So every two years, data must be transferred, or "migrated," to a new device. If that doesn't happen, the data may never being accessible again. Technology can advance too far ahead.

Anyhow, I just found the whole article a good read.

Climate change, probabilities, etc

Well, the scientific debate about how to properly think about the effects of climate change continues.

John Nielsen-Gammon makes a point about the extraordinarily warm March in much of the US not being quite as extraordinary as it seems. But in doing so, he seems to play into the hands of skeptics whose inclination has long been to shrug shoulders and say things like "what, so global warming might only add 1 degree to what was already a heatwave? Big deal."

Michael Tobis has a problem with this approach, and has a post with a good analogy, and some important diagrams.

And over at AGW Observer, a whole batch of papers looking at the Russian heat wave of 2010. Even Nielsen-Gammon seems to like this paper in that list, which gives a good explanation of how you can reconcile apparently conflicting statements about climate change and the heatwave.

Update: and as if on cue, a person commenting at John N-G's blog takes exactly the wrong message in the way that I (and others in the thread) thought would happen. It should be obvious which one I mean.

Unhealthy expeditions

Mind Hacks notes an extract from a 2008 Lancet article on mental health issues that arose during polar expeditions. I don't recall hearing about the last one before:

Frequently, the entire crew of a polar expedition would experience melancholy and depression, as was the case of the Belgica expedition to Antarctica in 1898–99. As described by the great polar explorer and expedition physician, Frederick A Cook, “The curtain of blackness which has fallen over the outer world of icy desolation has descended upon the inner world of our souls. Around the tables, in the laboratory, and in the forecastle, men are sitting about sad and dejected, lost in dreams of melancholy from which, now and then, one arouses with an empty attempt at enthusiasm.”

Cook tried to treat these symptoms by having crew members sit in front of large blazing fires. This baking treatment, as he called it, could be the first recorded attempt to use light therapy to treat symptoms of winter depression or seasonal affective disorder. Other expeditions, such as the Greely expedition of 1881–84, met a far worse fate than the Belgica exploration. In their attempt to establish a scientific base on Ellsmere Island in the Arctic, the crew of the Greely expedition was driven to mutiny, madness, suicide, and cannibalism, leaving six survivors of a crew of 25 men.

This interesting looking site "Time to Eat the Dogs" (about science, history and exploration) does say that there were "rumours" of cannibalism on the Greely expedition that circulated in the press at the time. Certainly, one man was executed for stealing shrimp from the communal mess pot. Mind you, they were stuck in the Arctic for 3 years before rescue. No wonder they got stressed.

British humour

Well, that went against expectations.

Over Easter, I took the kids to see the latest Aardman film, Pirates! - Band of Misfits. It got a very high 91% approval rating at Rottentomatoes from British and Australian critics; I liked Wallace and Gromit in their movie and TV outings; what could go wrong?

I thought it was pretty awful. Somehow, the jokes were obvious but just not laugh-out-loud, or even charmingly witty. You virtually had to be an adult to get most of them, but even then, they just came across as a bit, I don't know, trying too hard? Certainly, you could tell from the increasing restlessness of the younger members of the audience that the film was just not hitting that target at all. My kids said afterwards that it was only so-so. At least it gave me an opportunity to talk about Charles Darwin and evolution, but a springboard for some mild education is not why one goes to see an Aardman film.

Then today, my wife had hired Johnny English Reborn on DVD for the night (it's school holidays still). I knew it got so-so reviews (38% on Rottentomatoes) and (I now know) made an embarrassing $8,000,000 at the US cinema. (It made more than that in Australia alone.)

Yet we enjoyed it a lot. It's a well crafted, good looking movie with just the right mix of witty satire of James Bond and outright silliness, all without the excessive crudeness of the Austin Powers movies.

Strange how expectations can be upended.

Drug reform and economics

A week or two ago, the issue of drug law reform was again in the news because some advocacy group no one had heard much of before put out a bit of PR stuff about how a panel had met (largely comprising retired politicians, it seems) and decided the "war on drugs" had failed and there should be reform.

When I actually looked at their glossy press release, I thought it was remarkably lightweight and hardly worth the attention. One prominent person on the panel, Dr Alex Wodak, has been calling for drug easing for decades, although how he expects it to help the already heavy drug using population of inner Sydney that he treats has never been clear to me.

Anyway, I was quite happy to see on the weekend that a sort of backlash against the wooliness of this exercise appeared in both Fairfax and News Limited.

Bruce Guthrie wrote:

I am still wondering how the release of their wafer-thin report got the whole country talking about surrendering to illicit drugs. I'm left to conclude that the one-day wonder - for it flamed, burned and went out in less than 24 hours - spoke more to the state of media malleability than it did to our drug laws.

The product of a think tank called Australia21, the basis for its call seemed to be little more than a round table at which a bunch of retirees talked about what they should have done about the drug problem when they had jobs that empowered them to do it - people such as former West Australian premier Geoff Gallop and former federal police commissioner Mick Palmer.

But for real detail on why drug law reform should not remove prohibition, have a look at Henry Ergas' column in the Australian, and (perhaps more importantly, since he links to his source material), his blog entry.

I had not realised that there were economists had considered the question in such detail. While I am generally suspicious of Ergas, as he appears to be climate change skeptic and has devoted much time to criticism of the Gillard carbon pricing scheme, his take on drugs is detailed and (it seems to me) well argued.

I would also point out that you can tell that the issue is a complicated one when you even get strong disagreement on the issue amongst the readers of soft Left blog Larvatus Prodeo.

[And here's news: when checking that LP link, I just saw that the blog is ceasing to exist. Quite a surprise, even though it had become pretty dull in the last couple of years.]

CO2 coming first and last

Shakun et al. Clarify the CO2-Temperature Lag

Skeptical Science has a good explanation here of the recent paper in Nature which looked afresh at the question of whether CO2 increases preceded or followed the start of the bout of global warming that ended the last glacial period 18,000 years ago.

Nothing coming from nothing critiqued

‘A Universe From Nothing,’ by Lawrence M. Krauss - NYTimes.com

Found via Not Even Wrong, this review attacking Krauss' key idea in his book ""Why There Is Something Rather Than Nothing" is well worth reading.   The key point:

Where, for starters, are the laws of quantum mechanics themselves supposed to have come from? Krauss is more or less upfront, as it turns out, about not having a clue about that. He acknowledges (albeit in a parenthesis, and just a few pages before the end of the book) that every­thing he has been talking about simply takes the basic principles of quantum mechanics for granted. “I have no idea if this notion can be usefully dispensed with,” he writes, “or at least I don’t know of any productive work in this regard.”

But you should read it all.

Snakes and spiders (or at least, snake and spider)

I got quite a surprise today when outside to see if the possum was home (in her hidey hole under the deck just outside the front door).    A rather large (well, about a metre, which is large enough) snake on the rocky garden bed spotted me before I spotted it, and shot off at high speed in front of my feet into the bushes.    Snakes going past me at a distance of 50 cm or less is too close for comfort, no matter what species they are.

The good thing, I suppose, is that  although it was out of sight very quickly, I did at least get to see that it was pretty much a uniform olive green colour, and looking at this website, I would be inclined to think it was a common green tree snake, which is non venomous.   Most of the dangerous snakes seem to have some pattern or banding on them, although the potentially dangerous yellow-faced whip snake seems devoid of pattern too.   In fact, now that I look at this other site, the whip snake seems a distinct possibility.  I mean, do green tree snakes end up on the ground very often? 

Despite living in this house for about 8 years now, with rather large bushes and trees in the front, and bushy neighbours’ gardens, as well as rats in the roof and (sometimes) seen in the back yard, this is the first snake of any kind I’ve ever encountered.  I’m sure they must be around, but out of sight out of mind is the best policy as far as snakes are concerned.

As for spiders, this one was sitting prominently in the sun this afternoon, and stayed still for a close up with my cheapish camera.  

The body colours remind me a bit of the patterns of Jupiter. (Just a little.):

It would appear to be a female St Andrews Cross spider.  Now you know.

Fear of white

A review of White Bread, a new book about our nation’s fear of flour. - Slate Magazine

What an interesting story told here about the history of white bread, and how it's been the subject of much condemnation well before my lifetime.  Some extracts:

 As Aaron Bobrow-Strain makes clear in his epically well-researched White Bread, our culture’s tendency to focus what we as individuals put in our mouths often goes along with classism and xenophobia. Just as whole wheat acolytes pity white-trash white-bread eaters, and gluten-free converts showcase their discipline through vegetables and lean proteins, so, too, did turn-of- the-century crusaders attempt to spread the gospel of good food to less enlightened masses.

Between 1890 and 1930, Bobrow-Strain writes, Americans transitioned almost completely from homemade bread to store bought bread—and specifically to bread made in large factories. Hygiene fears were a major reason. The emerging understanding of germ science led pure food crusaders to preach against the dangers of mother’s kitchen, which couldn’t hope to achieve the level of cleanliness of a large bread factory, nor the heat necessary to kill the “yeast germs.” “You and your little oven cannot compete,” one newspaper article informed women after the turn of the century. Scientists and food reformers also warned against mom-and-pop bakeries, whose reputation for substituting cheap substances like chalk and alum was further undermined by the presence of so many swarthy immigrant workers, whose hygiene was considered suspect.

White bread, untouched by human hands and carefully wrapped for hygienic transport, became a symbol of purity....

But during the '20s and '30s, the nation was gripped by panic over white bread. A wave of experts with questionable pedigrees began warning about white bread’s nutritional content, harkening back to the teachings of 19^th-century ascetic Sylvester Graham, who believed that refining wheat undermined God’s intent. (Graham had a number of interesting theories, including that consumption of meat, seasonings and rich foods lead to rampant masturbation.)

Dietician and radio show host Alfred W. McCann claimed that 400,000 children a year were sent to “little graves” because they were raised on white bread. Food pundits said that white bread could cause blindness and disfigurement. A 1912 article in a journal called “Life and Health” made the dubious claim that in countries where there was no white bread, there was no cancer. Bobrow-Strain writes that white bread was implicated in a slew of illnesses including “diabetes, criminal delinquency, tuberculosis … rheumatism, liver disease, kidney failure …” White bread’s fortunes sunk, and bakers, who preferred white flour in part because it was cheaper to mill and could be stored longer, were beside themselves.

The article goes on to explain that the food industry got pro-active, and by the 1940's, adding vitamins was one way they successfully fought against the anti-white cranks.   (Actually, as a child, I don't recall seeing any brand of bread advertising its additives, like they do now.  Maybe Australia never succumbed to fear of white bread?)

All very interesting.

More religion reading

I've been looking around for religious themed stuff for Easter.

Slate is having a hard time coming up with anything new. They have again posted a 2008 story on early Christian understanding of the resurrection, and I see that I linked to as a result of their 2010 re-posting of it.

I guess it is a bit of a challenge coming up with new ideas about it; unless, of course, you come up with something like the image on a cloth causing a whole misunderstanding. (See a few posts down below.)

In other religion stuff on the net, I see that Stephen Crittenden has been writing articles at the Global Mail website, and they are pretty good. One is a summary of the story about the forced resignation of Bishop Morris of Toowoomba (a story about which I have always had some trouble finding the details); and a somewhat more critical than I expected review of the troubled leadership of recently resigned Archbishop of Canterbury Rowan Williams. (Williams is only 61, I learned to my surprise. His eyebrows seem decades older than that.)

I only know of Crittenden because of his hosting the (now axed) Religion Report on ABC's Radio National, but I see from his Global Mail profile that his background is more in arts and culture generally. He's not snobbish about it, though, writing a piece about how much he likes the Simpsons. (He notes with approval some American analysis that points to the way it both satirises but re-affirms the nuclear family. As I have been watching it in re-runs a little more often lately, and catching up with episodes and evolving storylines over the years since I stopped regularly watching it, the number of times the show does this has been on my mind lately. I was also pretty surprised that the Simpson's Movie was so sympathetic to Flanders, given the degree to which he is routinely satirised for extreme religious conservatism.)

Anyway, I've strayed off religion haven't I...

How about this: a blog post from England about the question of why the Catholic Church still seems a little leery of cremation. However, given that, as with the writer of that post, I know of a Catholic Church with a newly installed columbarium (a place for keeping the ashes), it does seem that at the parish level, accommodation with cremation is being made (literally).
