Richard Dadd: Caravan Halted By The Sea Shore (1843)


Pounding up the packed M5 yesterday, I noticed that caravans are like a red rag to a bull for the rest of us drivers, even if they're doing a good speed. But I also used one or two in the middle lane as markers to see if staying in the outside lane is better than switching to whichever queue seems to be making better progress; it is.

And as I drove, I wondered whether there is a Best Place. Cornwall and Devon are so lovely, so do the people who live there go elsewhere on their holidays, and if so, why and where? You could do an experiment, perhaps using information from travel agents: find out where the majority in one location take their breaks, then go to that place and see where the locals take theirs, and so on. Would you end up somewhere that is perfect, or simply so poor that the natives don't go abroad? Would you end up back where you started? Would the trek never end?

Perhaps it is not so much about venturing into the unknown, as escape from the known. Gertrude Stein: "What was the use of my having come from Oakland it was not natural to have come from there yes write about it if I like or anything if I like but not there, there is no there there."

Richard Dadd: Artist's Halt In The Desert By Moonlight

Arabs - the Bedouin kind - have long caught the British imagination. Like birds, they seem free. Some of the happiest-looking photographs of the SAS are taken when they're wearing their shemaghs, and the first couple of lines of the following quote from James Elroy Flecker's "Hassan" appear on the memorial Clock Tower at 22 SAS' Stirling Lines base in Hereford:

We are the Pilgrims, master; we shall go
          Always a little further; it may be
        Beyond that last blue mountain barred with snow
          Across that angry or that glimmering sea,
        White on a throne or guarded in a cave
          There lies a prophet who can understand
        Why men were born: but surely we are brave,
          Who take the Golden Road to Samarkand.

I suspect that Flecker originally wrote the scene as a stand-alone tribute to the heart's desire for the journey without end or final purpose, like Tennyson's Ulysses, and only afterwards turned it into a drama (all the rest is in prose).

And so, with regret, passing Gormley's awful Willow Man at Bridgwater (now thankfully dwarfed by the massive, gaudy-green decorated shed of the Morrisons depot) we took the Golden Road back to Birmingham, intending to return to the West Country as soon as possible.

CORRECTION: Not Gormley - Serena de la Hey. Apologies to both.

Polluting the climate

There are a number of more or less feasible ways in which humans may influence climate, both locally and globally.

An interesting theory published by Professor Qing-Bin Lu back in May makes the claim that chlorofluorocarbons (CFCs) once widely used as refrigerants, cleansers, aerosol propellants and foam-blowing agents may have affected the climate as greenhouse gases as well as damaging the ozone layer.

The chemistry and physics behind CFC-induced ozone layer damage are fairly well established, although Professor Lu thinks the ozone-destroying reactions are initiated by cosmic rays rather than the usual explanation based on solar uv photolysis.

Whatever the initiating pathway to ozone damage, the Montreal Protocolcame into being in 1989 and appears to have been successful in controlling and reducing the use of CFCs linked to that damage.

However, Professor Lu claims that those same CFCs also warmed our climate because they happen to be powerful greenhouse gases.

Chlorofluorocarbons (CFCs) are to blame for global warming since the 1970s and not carbon dioxide, according to new research from the University of Waterloo published in the International Journal of Modern Physics B.

CFCs are already known to deplete ozone, but in-depth statistical analysis now shows that CFCs are also the key driver in global climate change, rather than carbon dioxide (CO2) emissions.

So we have yet another climate theory, but an interesting one because it seeks to account for both the late twentieth century warming from about 1970 to 2002 and also the recent warming hiatus from about 2002 to the present, data which the CO2 theory fails to explain. According to Professor Lu, as we phased out those CFCs, the warming stalled in spite of a continued rise in atmospheric CO2 concentrations.

Although the paper received some publicity at the time, such as here, here, here and here, it now appears to have sunk below the mainstream horizon. Which is a pity, because if nothing else Professor Lu’s work suggests we are some way from understanding basic climate drivers, let alone classifying them in order of importance.

In climate science, the elephant in the room is surely uncertainty.

Would you notice?

From Bloomberg Businessweek

Xerox is now saying that some of its scanners can alter numbers in documents, even at the highest resolution setting. It blames a software bug for which it does not yet have a fix. “We continue to work tirelessly and diligently to develop a software patch to address the problem,” the company said in an Aug. 11 statement.

The problem came to light when German computer scientist David Kriesel scanned a construction plan on a Xerox machine and noticed that it changed numbers on some of the room measurements.


Would you notice such a thing? I'm not sure I would.

UK carbon capture

Click Green reports:-
 
National Grid has successfully completed test drilling of a carbon dioxide storage site in the North Sea – a major milestone in delivering a storage solution for Carbon Capture and Storage (CCS).

Early indications are that the undersea site 65 kilometres off the Yorkshire coast is viable for carbon dioxide storage and will be able to hold around 200 million tonnes permanently. This is equivalent to taking ten million cars off the road for 10 years.

The drilling is a major milestone in its Don Valley storage work programme funded by an EU grant to advance CCS in Europe. The findings are significant as this type of storage site is common in Europe.

If we take that figure of 200 million tonnes of CO2 and compare it to a reported 35.6 billion tonnes of CO2 emitted globally in 2012, we may easily calculate that the National Grid CO2 storage project would accommodate global CO2 emissions for about two days. So after two days it would be full.
One might ask if that two days respite represents good value for money in terms of CO2-induced global temperature changes. Good value for the well owners no doubt, but good value for us?

Re cycling

We’ve just returned from a week in the caravan at Minehead, Somerset. We use Minehead as a base for walking in Exmoor and the surrounding area. Not quite as rugged as Derbyshire, but a most attractive area for walking.

Withypool to Tarr Steps and back via Knaplock is a fine circular walk if you are ever in the area.

One thing we notice about these caravan jaunts is how many caravans and motorhomes have a couple of bikes stowed somewhere conspicuous.

Another thing we notice is how rarely we see any of these cycle owners actually cycle off somewhere. The cycles are unloaded from the car roof or the back of the motorhome right enough, but after that brief burst of activity they seem to lie around as a mute sign of good intentions.

Can’t do that with walking boots I suppose.

Polkerris

We were lucky: a young couple having an in-car heart-to-heart vacated their space for us at the Rashleigh Inn. We'd gone there to catch the westward view over the bay, where the BBC Weather site had forecast a clear sunset.

It was a gray evening and the tide was out. Adults and children wandered over the harbour beach and wall. A wraith of mist stood on the sea over by Charlestown, as though someone had lit a bonfire on the water.

 
In we went and ordered a pasty, which turned out to be locally made and excellent. I nicked chips from my wife's plate. We sat at a long table under a large portrait of a sixteenth century Spaniard in his fine clothes and chain of authority, his gilded helmet beside him. A shih tzu and a Jack Russell-terrier cross fidgeted at our feet, while their middle-aged owners examined a property online and discussed ideas for refurbishment and building a new house on the back lot. At the bar counter, an old man with a bent back sat open-eyed and unmoving, while the evening swirled about him.

NS&I to hit pensioners on Armistice Day

"Tens of thousands [of] customers with old National Savings & Investment savings accounts will see returns cut in November, it emerged today.

"The changes affect savers who took out an NS&I Savings Certificate before 1996.

Roughly £745m is held across 967,000 of these accounts, according to NS&I. The government's savings arm told The Telegraph that the return on 89,057 accounts, typically held by older savers, will fall from November 11, 2013."
 
http://www.telegraph.co.uk/finance/personalfinance/10233444/NSandI-reduces-rates-again-hitting-90000.html

The Telegraph also says:

"NS&I was created in 1961 as the Post Office Savings Bank to encourage saving and attract deposits for the Treasury to use running the country. These two tenets remain today. The simplest way to raise money is to offer alluring rates to savers. However, NS&I is bound by rules that force it to balance the interests of three parties: the Government, savers, and the banking industry.

"A flood of money going into NS&I coffers has upset this balance and the Government has ordered NS&I to stop taking so much money. As a result it has cut rates and accounts to dissuade savers. The latest version of NS&I Savings Certificates is no longer on sale."

Yet again, the Treasury shows that it has forgotten its own history, or feigns to have done so. As I have shown here and to my MP, both the Government and the Opposition expressly recognised a social obligation to pensioners to protect them from inflation, when Index-Linked Savings Certificates were first introduced in 1975. This was made clear in exchanges in both the Commons and the Lords (please see the link just given, for details).

I don't know whether the choice of Armistice Day for these new changes to take effect, is a deliberate insult to the elderly, some of whom may still recall the last World War, or simply another example of the crass, oblivious obtuseness that I am coming to expect from the finely-honed minds of the Treasury.

At least there is the option for existing holders to switch to new index-linked certificates - but the rest of us are excluded from making fresh purchases. And this still leaves open the question of how RPI may be manipulated in future to minimise returns to savers.

I read some general trends here: the Government is quietly abandoning its duty to keep inflation down, its grip on the public finances is slipping, and the public (rushing to NS&I for safety) can see that the Emperor has no clothes.

One commentator on the Telegraph article (1066goldberg) says buy physical silver; another (oldkingkole) says he doesn't understand the logic; I think I do.
