North Korean follies
Somehow, the fact that Pyongyang has an unfinished 105 story pyramid-shaped hotel had escaped my attention, until now. Interesting.

Another little, tiny cause for optimism
According to the article:
"When the cost of a white LED lamp comes down to about $5, LEDs will be in widespread use for general illumination," Sands said. "LEDs are still improving in efficiency, so they will surpass fluorescents. Everything looks favorable for LEDs, except for that initial cost, a problem that is likely to be solved soon."
He expects affordable LED lights to be on the market within two years.
A little, tiny bit of optimism
Despite the title, it is basically about the importance of (and relative ease) of saving rain forests to reduce CO2 emissions.
It even ends with this surprising claim:
Bush already has approved several significant tropical forest conservation projects in Guatemala, Costa Rica, Panama and elsewhere. With this deal, Bush could legitimately claim that he'd done far more, far sooner, for far less money to stop global warming than either the Kyoto Protocol or the failed congressional climate bill would have.
The Carbon Wars
So, this has got me thinking: what would it take to reduce CO2 if you were going to let warfare be part of the cure? Some immediate thoughts: submarines take out coal-exporting ships; cruise missiles for coal fired power stations; electro magnetic pulse weapons to take out power infrastructure. Encourage an insurgency by those hoards of young, sexually frustrated Chinese men who can't find a wife to overthrow the government. (They'll be so crazy they'll want to turn the country back into an agrarian society that does not have access to abortion or birth control, just so there can be women again!)
Of course, the other way of dealing with this is to let a mad ex-military character with a Captain Nemo complex run a private navy of nuclear submarines to do the West's dirty work for them. Just have to leave the gates of a nuclear submarine base open, with a little sign on the front "gone to lunch, please do not steal the submarines."
Ah, I'm amusing myself too much. Must go do some work before the tax office drags me away.
News Limited and global warming
I suppose it can be seen as confirmation that Rupert is more hands off than most people on the Left have previously assumed.
[Speaking of the Green Paper and the Left, it's been an odd sensation to be posting comments at Larvatus Prodeo on side with the lefty idealists in criticising Rudd for wimping out and not coming up with effective plans, instead of the political pragmatists who are simply happy that the fact that an ETS, any ETS, is coming. As I said at LP, the problem with schemes that are all spin and no substance is that they lull people into thinking a problem is being tackled, when in fact it continues to get worse, and the political cause of getting more serious action can be made all the more difficult.]
As for Brisbane, this winter has been quite damp and not terribly cold, and I note that quite a few spring flowering plants are starting their bloom already. (Azaleas, some peach tree the neighbour has.) The forecast temperature for the weekend is mid-20's, which is quite warm for July. Not sure how its going down south, but it seems an early spring here.
The Quiggin mystery
I suspect that operatives for Kevin Rudd and Penny Wong have been holding him captive in a basement somewhere in a Commonwealth owned building in Brisbane, threatening to never let him grow a beard again unless he comes out strongly in support of their plans.
Just a theory.

Garden project of the future
Geez, one of these would really impress my son. Pity it seems you can't buy them off the shelf.
Louvre goes Islam
Interesting story on the Louvre's new section for Islamic art.
More disaster talk
The suggestion is that it was massive underwater volcanism that led to the anoxic oceans and mass extinctions of 95 million years ago.
If true, I suppose it is half-way encouraging that high levels of atmospheric CO2 alone might not lead to anoxic oceans. But, this is not something I feel particularly inclined to run the risk on.
The Nature article I linked to a couple of posts back argued that the world could reach 1000 ppm pretty easily. Here's the relevant section (if you are really lazy, just read the parts I have put in bold):
The goal of climate mitigation is to avoid dangerous human-caused impacts, which science suggests would mean limiting total warming to 2 °C above preindustrial temperatures. In turn, this would require keeping atmospheric concentrations of carbon dioxide below 450 parts per million (p.p.m.). According to the IPCC's Fourth Assessment Report in 2007, model studies based on our current understanding of climate–carbon-cycle feedbacks suggest that to stabilize carbon dioxide levels at 450 p.p.m. could require that cumulative emissions over the twenty-first century reach only about 490 gigatonnes of carbon (GtC), which equates to less than 5 GtC per year1.
Similarly, stabilizing atmospheric carbon dioxide levels at 1,000 p.p.m. would require cumulative emissions this century of only about 1,100 GtC. In other words, if annual emissions average 11 GtC this century, we risk the real, terrifying prospect of seeing 1,000 p.p.m. carbon dioxide in the atmosphere and a 'best estimate' warming of a staggering 5.5 °C by the end of the century.
Carbon emissions from the global consumption of fossil fuels are currently above 8 GtC per year and rising faster than the most pessimistic economic model considered by the IPCC2. Yet even if the high price of energy from fossil fuels and power plants combines with regional climate initiatives to slow the current rate of growth somewhat, we will probably hit 11 gigatonnes of carbon emissions per year by 2020.
Lomborg on emissions trading
Doesn't sound particularly controversial, what Lomborg has to say about cap and trade schemes. (They are - relatively - politically palatable but aren't at all likely to do enough to make a significant difference.)
Lomborg suggests a much more serious commitment to R&D to get solar power costs down.

Emissions trading already too late?
For anyone out there (if there is anyone) who thinks emissions trading schemes are likely to do enough to limit CO2 fast enough, have a read of the above detailed opinion piece that was in Nature in June 2008.
It argues:
The limits of a strategy built around carbon pricing can be seen in the European Union's Emissions Trading Scheme, the world's largest system for pricing carbon and trading permits. A full decade after signing the Kyoto Protocol, European nations finally have in place a cap-and-trade system with a significant price for allowances, namely US$40 per metric ton of carbon dioxide. Yet utilities in Italy, Great Britain, the Czech Republic and Germany are reported to still be pursuing new coal-fired plants4, so we must clearly go beyond pricing carbon.The whole scenario set out in the article about how difficult it will be to achieve stabilisation at 550 ppm is pretty depressing, really. But the author argues that:
...such is the urgent need to reverse emissions trends by deploying a multitude of low-carbon technologies that we must rely on technologies that either are already commercial or will very shortly be so. Fortunately, venture capitalists and public companies have begun to inject many billions of dollars into the development and short-term commercialization of most plausible low-carbon technologies. Governments should now focus their R&D spending on a longer-term effort aimed at a new generation of technologies for the emissions reduction effort after 2040, but the notion that we need a Manhattan Project or Apollo programme for technology development is mistaken. Instead, what is urgently needed is an effort of that scale focused on the deployment of technology.It's all interesting, and well worth reading.
This is serious, but still...
Descent into tabloid
The Times has entered well and truly into tabloid territory by running this strange piece which paints sister/brother incest in a soft-porn, soft-focus, filtered glowing light sort of way.
Given the number of comments, many have taken offence, although quite a few have been overcome by the faux romanticism of it.
I have been meaning to write something of sex, emotion and morality, in light of the Anglicans fight over homosexuality, and this article might just prompt me to do it. Someday.
Meanwhile, I'll just take it as another sign that Great Britain is indeed in a weird downwards spiral of decay.
Poorly chosen words
Rowan Williams invites criticism again:
Discussing differences between the religions, Dr Williams acknowledges that Christian belief in the Trinity is "difficult, sometimes offensive, to Muslims".More to the point is why it should be considered "offensive," by anyone.
Or alternatively, if you allow that people can be justifiably "offended" by members of other faiths believing that they are wrong, then Christians should be allowed to find Islam offensive too. But if everyone can claim offence, there is hardly any point in raising the issue.
Great moments in science
The first line from the above report:
AUSSIES who find themselves under threat are more likely to shoot at Muslims, especially if they're in a good mood, a study claims.Just how many people find themselves both under threat from Muslims and in a good mood, I wonder.
How helpful
It's not often that I link to anything at LP with approval, but yesterday I was quoting Greenpeace, so I may as well continue my out-of-character run.
I mean, it is pretty ridiculous to be fretting about reducing our relatively tiny emissions while shipping millions of tonnes of coal to countries to burn or use in whatever manner they like.
The ALP thinks you should not sell uranium to countries that don't sign up to obligations to use it properly, yet when it comes to coal anything goes. (Has there been some talk of helping China build efficient power plants?; I can't recall. But there is certainly no legal tying of coal exports to any such efficiencies in its use.)
If you want to get top marks for idealism, and leading by example, then you would not cite the response "well if we don't sell it to them, they'll just buy it elsewhere."
UPDATE: those LP-er's are not taking the government's greenhouse plans at all well. Yep, it was a pretty good election for the Liberals to lose.
I think somewhere here before I have suggested the best answer to global warming may be for the US to wage war on China. (Well, if you must, just a limited war on their coal-burning facilities. Cruise missiles could be very handy that way. If the Chinese want to retaliate against US coal power stations, so much the better!) I work on the theory that there are very few problems in the world that can't be solved with high explosives.
Don't say I am not trying to be helpful.

Local problems with CO2 sequestration
See the link for a short but interesting story on plans (and the initial pilot project) for CO2 sequestration in Australia.
Apparently, the current cost problem is more in the CO2 capture technology, not the storage.
I'll take their word for it, but I still assume that a major cost in the future will be getting the CO2 to the sequestration site. In this article they talk of using the Moomba area, which already has pipe in place which could be used for transporting the CO2. But for other areas, surely the transport costs are going to be huge.
I see that the trial Otway project will pump 100,000 tonnes of CO2 into the ground. Sounds quite a lot, but how much CO2 does Australian power generation generate each year? According to this BBC site: 205,000,000 tonnes. So the total Otway project (I am not sure over what period it runs) will remove about .048% of annual emissions.
See why I remain deeply sceptical about this as a concept?
UPDATE: here's a generally sceptical look at CO2 sequestration from the 7.30 Report earlier this year. (I missed it at the time.) I see that the 200 millions tonnes a year figure seems correct, but it will rise to perhaps 300 million by 2030. (!)
It just seems a hopeless task. Surely you would be better off giving high priority to decommissioning coal powered stations and replacing them with, well, virtually anything. (Natural gas as an interim, it emits much less. Then nuclear and solar.)
UPDATE 2: apparently, the government (and Martin Ferguson in particular) is a believer in sequestration. All to be revealed tomorrow, perhaps.
I also wonder how hard the government is looking at the possibility of using "algae reactors" to scrub CO2 from power stations? Here's an article from a 2006 CSIRO publication in which an American company argues that it has many advantages over sequestration.
The company is GreenFuel Technologies, and its FAQ section is worth reading. They estimate that, for an average American coal fired power station, you would need 3400 hectares of algal farms to get a 40% reduction in CO2. Sounds a hell of a lot, doesn't it? (A square kilometre is 100 hectares.) But then solar farms are not exactly small either. Maybe I would be aiming for less than 40% reduction....
Still, sequestration is not a walk in the park either, and at least algal farms have a potential product at the end which may help offset the cost. (It is also less energy intensive. You have to remember with CO2 sequestration, you have to use more energy just to get the CO2 out of the exhaust.)
UPDATE 3: Greenpeace put out a paper in May 2008 detailing why it is against sequestration. In the section on Australia, it says:
In Australia, CCS would lead, at best, to a 9% emissions reduction in 2030 and a cumulative emissions reduction from 2005 to 2030 of only 2.4%.[88] This is partly due to the lack of suitable storage locations. For example, in the Newcastle-Sydney-Wollongong area of New South Wales and at Port Augusta in South Australia, which together produce about 39% of Australia’s current net CO2 emissions from electricity generation, there are no identified storage sites within 500 km of the coal-fired power stations.[89] In comparison, a modest improvement in energy efficiency could – at zero or even negative cost – decrease emissions in 2030 by about the same amount, and cumulative emissions by twice as much.[90]Well, they might just have a point.
Henderson and the Pope
Gerard Henderson's take on the current round of Catholic bashing is spot on.

Joe's pain
Joe Queenan writes a very funny column that confirms all my suspicions about what passes for modern classical music and opera. (The stuff that seems to appear once and is rarely heard of again.)
His contention: it is not popular because it is generally awful. Queenan says he has tried, really tried, to get into it, but failed:
When I was 18, I bought a record called The New Music. It featured Kontra-Punkte by Karlheinz Stockhausen and Threnody for the Victims of Hiroshima by Krzysztof Penderecki. I was incredibly proud of myself for giving this music a try, even though the Stockhausen sounded like a cat running up and down the piano, and the Penderecki was that reliable old post-Schoenberg standby: belligerent bees buzzing in the basement. I did not really like these pieces, but I would put them on the turntable every few months to see if the bizarre might one day morph into the familiar. I've been doing that for 40 years now, and both compositions continue to sound harsh, unpleasant, gloomy, post-nuclear. It is not the composers' fault that they wrote uncompromising music that was a direct response to the violence and stupidity of the 20th century; but it is not my fault that I would rather listen to Bach. That's my way of responding to the violence and stupidity of the 20th century, and the 21st century as well.Queenan writes that this year when he did see an audience respond reasonably well to a new composition, the explanation is that:
...nothing thrills a classical music crowd more than a new piece of music that doesn't make them physically ill.Quite the wit, is Joe.
