Your weekly ocean acidification news

Comment on "Phytoplankton Calcification in a High-CO2 World" -- Riebesell et al. 322 (5907): 1466b -- Science

Readers interested in my ocean acidification posts* will recall that there was a big surprise earlier this year when one study suggested that one species of calcifying phytoplankton actually got substantially heavier with more CO2 in the water.

The suggestion was that this may work as an important new CO2 sink, and was quite contrary to previous studies which showed the coccolithophore shells getting smaller with increased ocean acidity.

There was some muttering at the time by other scientists that this study could have been flawed, and now, see the link for a detailed comment by a group of scientists who think they have the problems with the experiment.

The comment is worth reading as setting out the basic issues with acidification and calcification.

Basically, this group still sounds very pessimistic about the "winners" outweighing the "losers" in ocean acidification.

* and who knows if there are any? - no one ever comments on those posts, which just encourages me to continue grinding my teeth about how most of the world is ignoring this issue.

The big questions

Why it's not as simple as God vs the multiverse - New Scientist

How could you resist having a look at an article that covers God, the multiverse, and morality?

(You could? What are you doing here then?)

A novel idea

Seawater holds key to future food

Farm plants that grow in salt water (and not just seaweed.)

Plants such as sea kale and asparagus-like samphire, which grow along the coast in many countries have been eaten for thousands of years, but it is only recently that their potential has been seen as a substitute for more traditional commercial crops.

In The Netherlands sea kale is now farmed commercially and finds a ready market says Professor Rozema.

Miyazaki talks

An audience with Miyazaki, Japan's animation king | The Japan Times Online

For those who have seen any of Miyazaki's films, this interview is of interest.

(I'm not sure which of his films I would recommend to a new comer to his work. Spirited Away was good, but as with many of his later films, it does become a bit of a narrative jumble as it goes on. I think the simpler story lines of Totoro and Kiki's Delivery Service make for a better introduction.)

The problems of cap and trade

Carbon Trading: Environmental Godsend or Giant Shell Game? DISCOVER Magazine

A very easy to follow article here on the problems with emissions trading schemes.

Something Islamic and cool

Dezeen - Museum of Islamic Art by I.M. Pei

Mark it on your calendar: this blog today has a post about something Islamic that is also impressive and cool. (Well, at least it's something in an Islamic country, whether or not anyone Islamic can claim that much credit for it is debatable, but let's stop quibbling and get on with it.)

Qatar has a new Museum of Islamic Art, and the architecture, on display in the photos at the above link, looks very impressive.

And yes, I see the architect is I.M. Pei, a Chinese born American. Ha.

Bad news for Indonesia

Megathrust earthquake could hit Asia 'at any time' - environment - New Scientist
A devastating "megathrust" earthquake could occur at any time off the Indonesian island of Sumatra, according to new research. Previous quakes have failed to release all of the energy that has built up over hundreds of years, leaving the fault zone vulnerable to another large earthquake.

An unlikely prospect

12 years to halve UK CO2 - The Independent

Britain should adopt the world's toughest climate change target and slash nearly half of its greenhouse gas emissions in the next 12 years, the Government's new climate advisory committee said yesterday in its first report.

Emissions of carbon dioxide and other gases causing global warming should be cut by 42 per cent on 1990 levels by 2020, as long as there is a new global climate deal in a UN meeting in Copenhagen a year from now, said the Committee on Climate Change.

The recommendation for what is a massively ambitious and world-beating target – and a costly one for electricity consumers, who will face higher bills, perhaps of up to £500 a year

An active retirement

Two elderly men arrested for robbing supermarket in Sapporo

Akinori Kawamura, 55, a used goods recycler, and Masanori Hanakawa, 66, unemployed, are suspected of forcing their way into the supermarket after it closed, shooting the manager with a gun and fleeing in a car.

Police said the pair admit to the charge. They were quoted as saying they wanted money to get by and to enjoy a few other things. Police found a modified handgun, four iron bullets, and a large number of fireworks in Kawamura’s home. According to police, Kawamura said he put the gun together and made the bullets himself.

Nothing like taking personal responsibility

So, Andrew Sullivan says of George W Bush: "because he cannot address homophobia and cannot even say the word 'gay' in public or address this issue directly, his legacy in America is actually an increase in HIV transmission".

This is all a bit rich, isn't it, coming for a HIV positive man who, 7 years ago, was actively seeking "bareback" sex?

(Yes, I know, he claims he was only going to have unprotected sex with another HIV positive person, but even that is behaviour not entirely without sexual health consequences.)

What upsets Sullivan is that he (Bush) didn't use the word "gay" in a conversation about HIV. He then goes on about how homophobia amongst blacks being the biggest HIV problem in America.

Funny, I thought the issue was that black men do not identify readily as "gay," and wouldn't assume George was even talking about them if he used the word. How does Sullivan think using the word "gay" is going to work magic within the black community?

By the way, that story from The Nation about Sullivan's dating strategies notes that Sullivan's ad indicated he was also into "bi-scenes" (as well as orgies generally.) I will take this as adding credibility to my personal theory of why Sullivan hates Sarah Palin!

UPDATE: just stumbled across a recent, very detailed, and very explicit, article in Huffington Post which argues that "barebacking" between the HIV positive is almost certainly encouraging mutated, drug resistant strains of HIV. It is very critical of the way the gay community is, to a large extent, taking the view that HIV infection is not such a serious matter now.

Embed problem?

I'm told that this blog is sending off anti virus warnings for some, and it appears to be related to embedded Youtube. (I actually got a virus warning from a science blog that appears to have no videos on it.)

I use AVG (paid version) and am not having any problems, and it seems not entirely clear whether it is a "real" problem or not.

Still, in the interests of safety, and not annoying people, I'll delete the embeds in the last couple of posts. Maybe they can be re-instated later.

More anti-Dubai

Why I'd rather die than visit Dubai | Sathnam Sanghera - Times Online

Most remarkable from the above opinion piece:
According to the Lonely Planet guide to the city, one British tourist was arrested at Dubai airport and sentenced to four years in prison after 0.03g of cannabis - an amount “smaller than a grain of sugar and invisible to the human eye” - was found on the stub of a cigarette stuck to the sole of his shoe. Meanwhile, a Swiss man was reportedly imprisoned after customs officers found three poppy seeds on his clothes (they had fallen off a bread roll he had eaten at Heathrow), and a British woman was held in custody for two months before customs officers conceded that the codeine that she was using for her back problems had been prescribed by a doctor.

Clever bike

Sanyo to launch new electric hybrid bicycle
Equipped with a rechargeable lithium-ion battery, the "eneloop bike" takes the crossover between a normal bicycle and a moped one step further, aiming to tap growing interest in tackling global warming.

The system harnesses energy from braking when the bike goes downhill, and can add extra power equivalent to double the rider's pedal force for going uphill, in line with relaxed government restrictions on such systems.

The eneloop bike can travel 1.8 times faster than conventional bicycles thanks to the motor powering its front wheel, the company said.
They need to get rid of the Japanese style shopping basket on the front, though, for it to look cool enough in the West.

Doctors behaving badly

Arrogant, abusive and disruptive — and a doctor - International Herald Tribune
"About 3 to 4 percent of doctors are disruptive, but that's a big number, and they really gum up the works." Experts say the leading offenders are specialists in high-pressure fields like neurosurgery, orthopedics and cardiology.
...every nurse has a story about obnoxious doctors. A few say they have ducked scalpels thrown across the operating room by angry surgeons. More frequently, though, they are belittled, insulted or yelled at — often in front of patients and other staff members — and made to feel like the bottom of the food chain.
Interestingly, one researcher blames the way surgeons teach themselves:
Norcross blamed "the brutal training surgeons get, the long hours, being belittled and 'pimped' " — a term for being bombarded with questions to the point of looking stupid. "That whole structure teaches a disruptive behavior," he said.
Vast international readership: you can post anonymously here your true life experience with a "disruptive doctor". Everyone likes those stories, don't they?

Tracking down CO2

Carbon Detectives Are Tracking Gases in Colorado - NYTimes.com

Good article explaining the research underway to get a better understanding of where CO2 comes from and goes (otherwise known as the carbon budget):
...researchers think about half of the CO2 emitted into the atmosphere gets absorbed by oceans and land, but they do not know precisely where the gases come from and where they end up. This knowledge gap has serious policy implications; until it becomes clear where emissions are going, it will remain difficult to have verifiable credits for sequestering carbon.

“We need to make sure that carbon markets are affecting climate change, not just putting money in the hands of some companies and people,” said Lisa Dilling, an assistant professor of environmental science at the University of Colorado, Boulder.

A vexing challenge is that surface inventory assessments — based on measuring forests, agricultural fields and smokestack emissions, for instance — generally do not agree with atmospheric measurements.
This sounds like it may help a lot:

In January, the next frontier of atmospheric CO2 measuring instruments will begin when the National Aeronautics and Space Administration launches the first carbon-scanning satellite, called the Orbiting Carbon Observatory.

Each day, the satellite will orbit Earth 15 times, taking nearly 500,000 measurements of the “fingerprint” that CO2 leaves in the air between the satellite and Earth’s surface. The data will be used to create a map of CO2 concentrations that will help scientists determine precisely where the sources and sinks are — showing differences in trace gases down to a 1 part per million precision against a background of 380 parts per million CO2 equivalent.
Surprising they haven't had a satellite to do that before now.

Australia revisited

History in the Making: The Current Cinema: The New Yorker

Damn. The New Yorker had David Denby review "Australia" instead of Anthony Lane. Still, Denby took quite a strong and witty dislike to it, so the result is not too bad.

The previous post here said it was a "spoiler" for the movie, yet it didn't actually deal with how the movie ends. (Oddly enough, over the weekend many people were coming to the post via searches for the movie spoiler.)

For those still interested, the real movie ending appears to be explained here, but David Denby also appears to give it away to a significant degree (and with a killer final line):
At the end, King George summons Nullah to a rite of passage, a walkabout. Nullah’s disappearance into the desert, leaving the whites behind, is framed as a triumphant anti-colonial moment, but Luhrmann confuses the issue by accompanying the scene with, of all things, the stirring “Nimrod” passage from “Enigma Variations,” by Edward Elgar, the composer perhaps most closely associated with the glories of empire. With the same degree of appropriateness, Luhrmann might celebrate Barack Obama’s Inauguration with a thundering rendition of “Dixie.”
If it weren't 3 hours long, I would be tempted to see to confirm my suspicion as to how bad I would find it. But life is too short for that. And in any event, it can almost certainly be written off as a box office flop, and will be making an appearance in the DVD rental shop sooner than they expected.

Always their fault

The kindest cut: How circumcision is the secret weapon in the battle against HIV/Aids - The Independent

Here's a long article about the success of circumcision in Africa as a preventive step to dramatically reduce HIV transmission:
Flooding Africa with condoms and trying to change sexual behaviour has had little demonstrable impact. Research on an Aids vaccine has foundered and an effective microbicide is still not in sight.

The toll from the disease is staggering – an estimated 33 million people infected with HIV, and 25 million dead. Even more alarming, however, is that new infections are growing by 2.7 million a year, outnumbering the annual two million deaths. For every two people put on drug treatment, five more become infected.

Against this litany of despair there is now, for once, a message of hope – a chance of curbing, and even reversing, the epidemic. Circumcision, if rolled out across the continent, offers the first real prospect of saving lives by preventing infection on a significant scale. Estimates suggest that if universal circumcision were introduced across sub-Saharan Africa, it could prevent 300,000 deaths in the next 10 years and three million deaths over the next 20 years. It is sometimes described as a "surgical vaccine" – with good reason.

What's the bet that this will still not satisfy the very strange anti-circumcision movement, the believers in which will no doubt be writing letters to The Independent this very minute.
