A look back at economic pessimism

In comments in a post here yesterday, I was arguing that those economists who are optimistic on the cost of taking serious action on CO2 emissions probably have history on their side, in that there are clear examples of where government mandated changes for environmental reasons did not have the terrible economic costs that the industry initially claimed.   The examples I gave were the introduction of unleaded petrol, removing CFCs, and catalytic converters in cars.

Now, I was  really just going by memory on these, but I've looked up what was said about catalytic converters in the 1970's, and it's very interesting to read in retrospect.  These extracts are from a Thomas Friedman book:

From one extreme to another

Hello, Kurdistan :: Daniel Pipes

Gawd.  Daniel Pipes in this column notes that he used to oppose an independent Kurdistan in Iraq; now he thinks it would be a good idea for a transnational independent Kurdistan to be created in the region, looking something like this:



That'll go over well with Turkey and Iran.   Talk about your one extreme to another.

So which Australian politician is quoting this column with implicit approval?   Senator Blofeld Leyonhjelm.  (See his twitter feed.)   Along with his (apparent) view that cannabis should be sold from the supermarket, the government take over supply of ecstasy, gun laws be relaxed, and fixing the budget by a slash in both welfare and the top tax rate, he's a "big ideas" man with the luxury of not having to deal with the practicalities of ever putting them into effect.

An optimistic take on China and renewable energy

Economics: Manufacture renewables to build energy security

Quite a lot of surprisingly optimistic news on China and its rapid growth in renewable energy to be found in this article.  For example:
China generates more than 5 trillion kilowatt-hours (kWh) of electricity, about 1 trillion kWh more than the United States. China's rapid economic expansion since it joined the World Trade Organization (WTO) in 2001 has been based on fossil fuels: it consumes around 23% of the world's coal production for electricity. But fossil fuels alone cannot power the industrial growth the country needs to keep up with the West.

Since the mid-2000s, China has also pursued a low-carbon energy strategy. Investment in hydroelectric, wind, solar and nuclear-power generating facilities increased by 40% between 2008 and 2012 — from 138 billion renminbi (US$22 billion) to about 200 billion renminbi. The share of investment in fossil-fuel power facilities in China, meanwhile, fell from around 50% to 25% over the same period.
And for the big, big picture:
Our critics will counter that technology-based solutions raise concerns over the availability of industrial materials and land for building solar and wind devices and farms. But our calculations suggest6 that a global renewables push for an extra 10 terawatts of power-generation capacity could be achieved on current industrial scales over the next 20 years, by which time the world energy system would be well on the way to total conversion. Producing the extra 10 terawatts from renewables needed to transform global electric power would require more than 5 million square kilometres (about twice the size of Kazakhstan) filled with around 3 million wind turbines, 14,000 concentrated solar-power installations and 12,500 solar-photovoltaic farms. These technologies could perhaps be accommodated in the world's desert and semi-desert regions. The targets are large — but they are manageable compared with current world production levels of 1.75 billion mobile phones per year or 84 million vehicles per year6.


Yet more illustrations for the Right

Boy, isn't the increase in Antarctic sea ice getting a run for the money from the Right wing ignorance machine?

Looking around the web, here's a couple of comparisons for illustration:

The Arctic, today, at the end of summer, showing the extent of ice compared to a longer term average, compared to Antarctica with a similar comparison.



I'm not sure why even the likes of Andrew Bolt can't understand the point that loss of sea ice in summer in the Arctic is a much more significant issue for warming compared to an increase in sea ice in Antarctica in winter (because there is little sun in winter to have any effect anyway), but insist on adding up total sea ice and saying "Ha!" is what they do.

This recent paper also illustrates the complexity of the Antarctic situation, where there is the issue of the ozone hole and its contribution to circulating winds.   It appears that increasing winds have led to a decreasing or flat lining of sea surface temperatures much around the continent; and interestingly, a significant change in trend happened around 1980.

Climate change isn't simple, and not every effect at every part of the globe has been perfectly foreseen.

But it is clear to anyone who reads on the topic that the current Antarctic sea ice situation does not mean that global warming is not happening.

Even shorter version: they all hate each other?

The Christian Science Monitor has a short-ish guide to why the Islamic nations around Iraq and Syria are reluctant to be seen to be too involved in attacking ISIL, or whatever we're supposed to call it today.

Actually, I'm a bit worried that I found myself nearly agreeing with Rand Paul on something this morning, when I heard him on the radio saying this:
“I think the first 10,000 soldiers marching into battle need to be from Iraq, live in Iraq and need to be fighting for their homeland. The second 10,000 need to be from Saudi Arabia,” Paul said on Monday in explaining his support for the president’s plan. 
I feel rather ambivalent about  Australia's involvement.  Certainly, Abbott has had a "pick me! pick me!" enthusiasm about it that smells of seeking political advantage here.   On the other hand, actually using our Hornets for something useful is something that we probably should do every 15 years or so.  But overall, it still has an unpleasant feeling of an attempt to fix up what is essentially someone else's mess because we accidentally made it worse.

The big picture missing from The Australian

Doesn't the Australian today have yet another article promoting the Jennifer Marohasy screams of "Fraud!" against the entire Bureau of Meteorology?  Oh yes, it does, again smearing the Bureau on the basis of the claims of a biologist funded by a climate change denying fund.

I'm a little puzzled why the BOM doesn't come out and simply put these graphs more prominently on its website:


Here's the Bureau's explanation of the above graph:
Both adjusted and unadjusted temperatures show that Australia's climate has warmed. Since 1955 adjusted and unadjusted data are virtually identical. It is during this time that most of the warming has occurred in Australia.
The graph below shows temperature trends since 1910 from the unadjusted temperatures (AWAP), together with those that have been carefully curated, quality controlled and corrected for artificially induced biases (ACORN-SAT). Carefully curating and correcting records is global best practice for analysing temperature data.
 And the ocean temperature record around Australia follows a similar pattern:


 Again, why has the Right become so insistently dumb and gullible on matters of science?

Andrew Bolt, nuclear expert

Interesting to note that in Japan, some investigation statements relating to the Fukushima nuclear disaster have been released by the government, from which we learn this:
Plant manager Masao Yoshida envisioned catastrophe for eastern Japan in the days following the outbreak of the Fukushima nuclear disaster, according to his testimony, one of 19 released by the government on Sept. 11....

In his testimony, Yoshida described the condition of the No. 2 reactor at the Fukushima plant between the evening of March 14, 2011, and the next morning: “Despite the nuclear fuel being completely exposed, we’re unable to reduce pressure. Water can’t get in either.”

Yoshida recalled the severity of the situation. “If we continue to be unable to get water in, all of the nuclear fuel will melt and escape from the containment vessel, and radioactive substances from the fuel will spread to the outside,” he said.

Fearing a worst-case scenario at the time, Yoshida said, “What we envisioned was that the entire eastern part of Japan would be annihilated.”
In Australia, local nuclear expert Andrew Bolt was writing this:
No, there won’t be a nuclear explosion, “China syndrome” or “another Chernobyl”. The situation today is better than yesterday, and as each day goes by the chances of a big accident lesson. The nuclear fuel remains contained.

This scaremongering over the crippled Fukushima nuclear complex is extraordinary. 
So while the actual plant manager was freaking out about rendering a huge slab of his country uninhabitable, Andrew Bolt was writing "stop your stupid panicking, environmentalists." I think I know which person to trust more in terms of the seriousness of what was going on.

Why has the Right become so insistently dumb on matters relating to science, technology and risk?

Drink your lithium and be happy

Should We All Take a Bit of Lithium? - NYTimes.com

Here's a fascinating article about whether or not lithium in "natural" quantities in drinking water has a significant health benefit.
The scientific story of lithium’s role in normal development and health began unfolding in the 1970s. Studies at that time foundthat animals that consumed diets with minimal lithium had highermortality rates, as well as abnormalities of reproduction and behavior.
Researchers began to ask whether low levels of lithium might correlate with poor behavioral outcomes in humans. In 1990, a study was published looking at 27 Texas counties with a variety of lithium levels in their water. The authors discovered that people whose water had the least amount of lithium had significantly greater levels of suicide, homicide and rape than the people whose water had the higher levels of lithium. The group whose water had the highest lithium level had nearly 40 percent fewer suicides than that with the lowest lithium level.
Almost 20 years later, a Japanese study that looked at 18 municipalities with more than a million inhabitants over a five-year period confirmed the earlier study’s finding: Suicide rates were inversely correlated with the lithium content in the local water supply.
More recently, there have been corroborating studies in Greece and Austria.
Not all the research has come to the same conclusion.
Even allowing for that last sentence, why haven't I heard about this before?

Or maybe I have, but just don't have enough lithium in my diet.  (The article suggests it may help prevent dementia.) 

An innovative place to go looking for a new antibiotic...

Late movie review

I never got around to seeing Prometheus when it was at the cinema, and wasn't especially concerned because of the so-so reviews, but it turned up on commercial television last night and I did that rare thing that used to be common place - watch a Sunday night first release to free TV (I think) movie.

Well, what a complete and utter mess of a film.

It looks impressive for about the first 15 to 20 minutes or so, but my God does it go rapidly downhill in all respects after that.   As with Sunshine, this is a science fiction film in which it seems very big space ships are crewed by people who appear to be picked out of a hat, such that no one seems to know anyone else, everyone starts making stupid decisions and ignores anyone who says it's not a good idea, and the science of just about everything is dubious if not silly.  

It's a really awful script full of improbabilities, and the "big picture" of what's going on remains rather opaque all the way through.  Yet there is a sequel being made!   Why?

The only positive thing I can say is that it seemed surprisingly low on swearing.  But apart from that....

Update:   Unbelievably, I see from checking on Rottentomatoes that Prometheus got 73% approval rating; Sunshine, which I also disliked, got 75%.   But Oblivion, which I watched at home this last weekend on DVD (after seeing it at the cinema last year) got only 54%.    What gives?   Oblivion was about twice as enjoyable as those awful films. 

Technology news

Yessss!  Two months of insisting on staring at the glowing screens of the new Samsung Tab S every time I've been with anyone from my family anywhere near a shop that stocks them paid off!

I was given one (the smaller version) for my birthday last week, and it is awesome, especially if you're upgrading from one of the early Samsung Tab models, which now appears extremely underpowered as well as having a screen that looks like sandpaper.   (It never used to be a noticeably poor screen, but after looking at the ultrafine, colourful, better-than-real-life, screen that I've been using for a few days, I laugh at its primitive resolution.  [Insert mocking laugh.])

But apart from the screen, which I'll try to not mention another 5 times, what I thought on the old tablet was a slow wi-fi connection at the far end of the house turned out to just be slow processing speed.   The Tab S works likes lightning in comparison.

So, I'm very happy, and am currently on a new Tablet honeymoon that may see me posting less frequently.  The screen, the screen, the screen....I must look at it again...

Priorities of a pathetic government

May this year:
...this government has slashed more than $450 million from key science agencies that have all suffered substantial losses, including:
Today:
A controversial tourism facility at a Cadbury factory partly funded by taxpayer dollars looks set to go ahead, with the chocolate maker announcing the "globally relevant chocolate experience" should be signed off within weeks.
Tony Abbott promised a $16 million grant to the Hobart project during last year's federal election, however questions have since been raised about the generous pledge given the Coalition government's refusal to provide taxpayer assistance to fruit cannery SPC Ardmona.

The Julia show

There are quite a few humorous tweets going down about the Gillard appearance at the Union corruption royal commission, but this one is perhaps my favourite:

Senator Blofeld is a bit of a nut...

Libertarian Senator David Leyonhjelm, pictured here:
















sorry, I meant here:

is in the news today for having appointed Helen Dale, famous for getting into heaps of trouble for pretending to have a family background that was useful for promoting her novel. Well, she does have umpteen law degrees, seems to do nothing useful with them, and her blog is a bore, so she's qualified, but listen to what Leyonhjelm says about the fraudulent episode in Dale's past:
“I was impressed that she extended a work of fiction into the authorship, which I thought was entirely appropriate,” Senator Leyonhjelm told The Australian. “I regarded the controversy at the time as both absurd and amusing.”
 He's a nut.

Update:  more "fraudulently passing yourself off as someone you're not for notoriety and financial gain is hilarious"  analysis from Senator L:
"I recall at the time thinking it was hilarious, it was a big joke and she kept up the fiction for quite a while. Then, when they realised she was pulling their leg they turned on her, which I thought was very unkind."
 Update 2:   I'll make a prediction:  she will not be in the job for more than a year or two.

Update 3:  David Crowe does some sort of sucking up today for having released the story early, or something like that?  

Yesterday we learned that Paul "magic water" Sheehan has been to a libertarian conference, and also seems to think Ms Dale is the bees knees?    He notes this about a paper she gave:
Dale's presentation focused on social changes caused by technology, not expensive social engineering. Among many examples was a correlation between the removal of lead from petrol, paint and cosmetics and a decline in crime.        Practising law, she saw government regulation and compulsion as frequently having both adverse and unintended consequences.
Well, I hope her paper then went on to note that it was government regulation that forced the move to unleaded petrol, as I have the distinct recollection that there was resistance to the policy from motoring associations and oil companies.   I would like to see what the IPA was saying about it at the time, although, to be honest, I don't know that was as intensely ideological then as it is now.

Update 4:   Hey, I find something good to say - sort of - about Helen Dale's views as a libertarian.   She wrote only late last year:
5. Libertarians in particular need to drop their widespread refusal to accept the reality of climate change. It makes us look like wingnuts and diverts attention from the larger number of greenies who spew pseudoscience on a daily basis. That said, don’t confuse real science with greenie catastrophizing. When Matt Ridley pointed out (a) that climate change is real, (b) it is currently having beneficial effects, and (c) is likely to continue to do so for some time, he got a bucket of turds dumped on his head by both sides. Don’t do that. 
So, on the "up" side she should be off side with everyone who posts at Catallaxy then, her very very very good friend (he keeps telling us) Sinclair Davidson, Judith Sloan (who takes every opportunity to ridicule scientists and bodies pushing for a serious response to climate change), Kates, Moran, etc etc.

On the downside - one of the main figures she should be skeptical of is Matt Ridley, but she appears not to be.

And more downside - she's still happy to take a job with a Senator for a party whose official policy is to sit on the fence and do nothing because, you know, it kinda hates government doing things anyway...

I've read Andrew Bolt's blog today so that you don't have to.....

Tony's persistent woman problem

Tony Abbott was long said to have a "woman problem", which I am sure Andrew Bolt and his  acolytes who have migrated to Catallaxy have ridiculed as a bit of Leftist smear and imaginings.   (Obviously, though, Abbott or his minders knew it was true, given the way they made his daughters stick by his side every single minute of the election campaign.)

Today's Essential poll (indicating a government pretty firmly stuck at 48/52 TPP with Labor in the lead) also notes about Abbott's approval:
52% of respondents disapprove of the job Tony Abbott is doing as Prime Minister – down 2% since the last time this question was asked in August – and 35% approve of the job Tony Abbott is doing (down 2%). This represents no change in net rating  at -17.

84% (up 4%) of Liberal/National voters approve of Tony Abbott’s performance, with 9% (down 3%)
disapproving. 87% of Labor voters and 79% of Greens voters disapprove of Tony Abbott’s performance.

By gender men were 42% approve/48% disapprove and women 29% approve/56% disapprove.
Well, I'm gobsmacked that 84% of LNP voters approve of him; but still, the main point is that Tony has a persistent woman problem.

Hydrogen power cycle into the future

Australia's first fuel cell bicycle

This sounds like really clever technology:

UNSW researchers have built an Australian-first bicycle that can take riders up to 125 kilometres on a single battery charge and $2 of hydrogen.

One kilogram of the standard metal hybride is capable of storing 100 litres of hydrogen, but Aguey-Zinsou and colleagues at the Material Energy Research Laboratory in nanoscale (MERLin) at UNSW are now developing borohydrides that could
store the same amount of hydrogen using just 50 grams of storage material.

Hydrogen for the Hy-Cycle can be produced with as little as 100 millilitres of water. The water is split into its elements – oxygen and hydrogen – and the fuel cell recombines the hydrogen with oxygen to produce electricity.

However, Aguey-Zinsou envisions a future where riders could purchase
replacement canisters from a network of distribution points, rather than
needing to produce hydrogen.
But does it come in different colours*, and what will it cost?
