Central England Temperatures

As we all know, the Central England Temperature (CET) record is the world's oldest continuous surface temperature record, going back to 1659, although to put it mildly the early data has a number of defects. It can be downloaded from the Met Office here.

In an idle moment and as I live in central England, I downloaded the data  aiming to play around with various ways of presenting it. For example, the Met Office shows each monthly mean temperature as a difference from the 1961-1990 mean (fig 1) which brings out the recent warm spell very well.

fig 1
Only data from 1772 is used by the Met Office, as in Parker et al. (1992). By the way, the Parker paper highlights rather well the complexities and the adjustments made in compiling a long historical temperature record. It certainly isn't a list of thermometer readings.

However, if you simply plot the temperatures rather than the 1961-1990 differences (fig 2), the graph is rather more innocuous. After all, it's worth remembering that we experience daily and seasonal temperature changes far larger than those we are supposed to be alarmed about. 

fig 2
I see nothing wrong with either format. I'd use the Met Office approach if I had a reason to emphasise the recent warming spell. However, if I was wondering whether to move north to escape catastrophic warming, then I might use the simple temperature graph in fig 2.

fig 3
The graph above (fig 3) is the CET data from 1979 - the satellite era. Just for fun I've fitted a second order polynomial which appears to show that the CET temperature has peaked, albeit a very shallow peak. I don't yet see it as a trend though, but it is worth noting how easy it is to present the data in many different ways depending at least in part on your agenda. 

fig 4

For example,  the temperature record from 2006 plotted the Met Office way (fig 4) seems to show a rapid cooling trend. Maybe so, but as nobody knows where it will go in 2014, let alone the longer term, what conclusion do we draw from that? Don't try to build an agenda on temporary trends in cyclic phenomena is my conclusion - at the moment.

Finally, the month of June from 1659 to 2013 (fig 5) shows a flat linear trend over the entire three and a half centuries - h/t to sunshinehours for that oddity.

Rubbish! Incompetent UK Government blames EU

Pics: Guardian, Telegraph
"When rubbish piled up for weeks in 1979, it was a crisis; now it's an EU policy." That was my starting thought, after all the MSM (and Conservative Home) complaints about fortnightly municipal waste collections.

Not so. EU regulation in this area is about reducing landfill and packaging waste, especially rotting organic waste. To incentivise change, a landfill tax was introduced by the Conservatives in 1996, at two different rates. Currently the standard rate is £2.50 per tonne, but "active" (organic) waste is charged at £72 per tonne, rising this April to at least £80.

Local authorities' failure to meet recycling targets results in heavy expenditure on landfill tax, so to save money they have threatened to cut down on household collection frequency, and the Government compensated them to maintain the weekly service.

Germany and Austria manage recycling rates of over 60%, compared with the UK's 39% so it can be done; our national government is paying councils not to pull their finger out. Unless we want to disappear under a swelling mountain of garbage, we need to do something, whether or not we're told to do so by some supranational body.

I'm agin our membership of the EU because, among other reasons, I believe in democracy - and on constitutional grounds, I say we're not in the EU anyway, since we never gave our informed consent. But in the case under discussion, it suits Parliament to blame the EU for its own weakness in dealing with recalcitrant councils, whereas in other cases our Government pretends to make decisions that have already been handed down to them by Europe.

Getting out of - or as I'd prefer to say, confirming that we're not in - the EU is only the first step. The next is to clear out the Augean stables in Westminster and institute more open, responsive, responsible and competent government.

Freedom and survival

This week saw the death of Hiroo Onada, a WWII Japanese soldier who continued his guerilla war in the Philippines until 1974. Although he killed 30 indigenous people over these years, most of us must have respect for a man fighting on alone for so long.

Except he wasn't on his own for most of that time, as the Daily Mail reveals: "Three other soldiers were with him at the end of the war. One emerged from the jungle in 1950 and the other two died, one in a 1972 clash with local troops."

Lone survival is a familiar motif in films, not so much in real life. In some tribal cultures, the punishment for major crimes such as murder was not execution, but simply shunning. Without the material and psychological support of their community, most individuals would die. Even Alexander Selkirk, the inspiration for Defoe's Robinson Crusoe, nearly broke his back hunting game.

The multiple challenges facing us - economic, environmental etc - feed the fantasies of doomsters and individualists. But if and when a whole society collapses, the disaster crushes all, not just the weak and ill-prepared - where were the rich Mayans to be found after their civilisation fell? Not drinking chocolate in some comfortable enclave among the ruins.

However, apocalypse is another hackneyed cinematic motif. As energy resources dwindle and become more expensive, it's more likely, argues John Michael Greer, that we shall see a series of economic resets, rather in the way that the coals burning in a hearth fire suddenly shuffle a bit closer together from time to time. That's something for which we can prepare, he says, and lists a number of technologies that would go towards making a sustainable local economy.

So far, so good. Yet even a cooperating community has to consider external threats. Aldous Huxley's 1962 novel "Island" depicts a society that is orderly and designed for the happiness of all, using a combination of accommodative social mores, neo-Buddhist wisdom and side-effect-free psychotropic drugs. It is overthrown when foreign oil companies move in...

"Island" is an imagined resolution of the potential disharmonies at two of what I have called the "Three Levels Of Freedom" - the conflicting or self-destructive drives within the individual, and the relationship of the individual with the group. The tragic ending is caused by a conflict at the third level, one group (the islanders) versus another (the greedy and powerful outsiders).

Worries about various potential dislocations in the global trading system are leading commentators such as Charles Hugh Smith to consider how to increase local resilience, as for example in Thursday's post, "A Thought Experiment In American Autarky". Here he is thinking on a national level, but the deeper the crisis, the greater the possibility that even countrywide arrangements could break down. Empires and nations have fractured before, as Germany did in the Middle Ages.

Most likely to survive, perhaps, are communities large enough to provide themselves with all the necessities of life (and sufficient diversity to stave off the problems of inbreeding), but protected from outside disruption by remoteness or difficult terrain. That reduces the threat of Level Three conflict, especially as technological deterioration in the long term makes it harder to wage war over long distances and great obstacles.

But material goods are not enough. There is also what one might term social wealth - shared ethical and cultural values that promote harmony and mutual support. Otherwise there will be unnecessary suffering and tensions that could tear the community apart - as Norman Cohn demonstrates with multiple horrific examples in his famous work about medieval uprisings, "The Pursuit Of The Millennium". Cohn's thesis is that the ground for revolution was prepared by want and insecurity, especially among the growing proletariat in urban areas.

Ironically, the trigger for insurrection was often an individual who had overcome his internal conflicts - achieving Level One freedom - and so could act without moral inhibitions. If one accepts the Freudian tripartite division of the psyche, such people had extinguished their superego and as full-blown psychopaths could lead their fellows in a merry, lethal dance toward ultimate calamity. (A major modern example would be Chairman Mao who, we see in a chilling 2005 biography, defeated his father's authority when a boy by threatening suicide, and one of whose early poems looked within himself and saw a mighty rushing power like a great storm, unstoppable.) So society has a stake in the mental and spiritual health of all its members, as well as their material well-being.

The long-term survival of humanity, and its prospects for reasonable contentment, requires vigilant and equitable balancing at all levels, from the mental stability of individuals, to whatever is the accepted "social contract" in society, to careful international diplomacy and robust economic arrangements. The struggle for freedom and happiness is not a solitary quest but a multi-player, multi-dimensional one; none of the Three Levels can be ignored.

Disconnect

(Click to achieve enlightenment)
The image of Tianmen Square's giant TVs broadcasting the sunrise to relieve the smoggy gloom struck me as a metaphor for much more than China's industry and environment.

If we tore our eyes and ears away from the agenda-infested media, what conclusions would we draw from our own experience? What plans of action would we form?

Curry on climate

Worth reading  is Judith Curry's statement to the Committee on Environment and Public Works of the United States Senate - Hearing on “Review of the President’s Climate Action Plan” 16 January 2014.

For example :-

The premise of President Obama’s Climate Action Plan is that there is an overwhelming judgment of science that anthropogenic global warming is already producing devastating impacts, which is summarized by this statement from the President’s Second Inaugural Address:

Some may still deny the overwhelming judgment of science, but none can avoid the devastating impact of raging fires and crippling drought and more powerful storms.

This premise is not strongly supported by the scientific evidence:

• the science of climate change is not settled, and evidence reported by the IPCC AR5 weakens the case for human factors dominating climate change in the 20th and early 21st centuries 

• with the 15+ year hiatus in global warming, there is growing appreciation for the importance of natural climate variability 

• the IPCC AR5 and SREX find little evidence that supports an increase in most extreme weather events that can be attributed to humans, and weather extremes in the U.S. were generally worse in the 1930’s and 1950’s than in recent decades.

Not only is more research needed to clarify the sensitivity of climate to carbon dioxide and understand the limitations of climate models, but more research is needed on solar variability, sun-climate connections, natural internal climate variability and the climate dynamics of extreme weather events.

Alice puts her foot down

From Wikipedia

Alice is driving along the main road through the Derbyshire village of Wessington. It is a quiet time of day and she notices that she is well above the speed limit. Alice slows down and luckily there are no unwelcome consequences such as a speeding ticket.

Fragmented reality is the reality we live in, a world where most common events are left unexplained because life moves on and we have no time to work out the explanation. Even so, is it possible for Alice to explain why she broke the speed limit in a pleasant little place like Wessington?

Where should she begin? Should she begin with a sociological, psychological, political, legal, modern or old-fashioned view about motorists who break speed limits?

Presumably she will not favour all these points of view – but is there a leading candidate? To make Alice’s problem a little more difficult, let us concoct a list of ideas she might consider if she decides to look at this question from every possible point of view she can think of.

  • Alice may get an emotional buzz from driving fast.
  • Her psychological state – she may be anxious to get home.
  • Her knowledge of Wessington – it may be a place she doesn’t know.
  • Road layout and road sign visibility. Alice may not see the speed limit signs.
  • Body maps and memories located in specific areas of her brain and specific neurological events may explain her behaviour in broad neurological terms.
  • Complex biochemical processes in Alice’s brain may explain her speeding in terms of the molecular structure of her central nervous system.
  • Alice's actions may involve trillions of electrons in the relevant areas of her brain.

Obviously as we go down this list, we soon leave behind the real world of Wessington, motorists and common sense.

There are some broadly usable ideas at the top of the list and scientific theory lurks at the bottom, but we do not have a way to knit them together and it seems unlikely that we ever could. Real life is left behind well before we reach ludicrous notions of electrons in Alice’s brain.

So which is best – top down or bottom up? Rigid determinism seems to suggest that everything from electrons in Alice's brain to her foot on the accelerator are all part of a coherent whole.

Rigid determinism is impossible to prove in real life situations though. So does anyone actually believe it?

Sherlock

Sherlock and Watson - from the BBC

Last night we watched an episode of Sherlock. If you haven’t seen the show, it’s a BBC version of Sherlock Holmes set in the bonkers world of TV drama and a magically deluded version of the present. Not a hansom cab to be seen.

Sherlock is played by Benedict Cumberbatch who makes a good Holmes at times, but is wasted here. Dr Watson is played a rather wooden chap I’ve seen somewhere before and Moriarty by a guy who comes across as a little boy pretending to be insane.

Last night’s plot was something to do with an all-powerful blackmailer who supposedly has the dirt on every important person in the country. Which rather confirms something we all know anyway, but that's by the by. The blackmailer was played by a neatly bearded chap with rimless spectacles and the subtle, spine-tingling menace of a meringue.

At one point, Dr Watson’s wife Mary is dressed in paramilitary black and about to shoot the blackmailing villain with her silenced pistol, but Sherlock intervenes so she shoots him instead. As you do. In a lucid moment she appears to know Holmes is the good guy but shoots him anyway.

The reason why Mary might make this superficially lamentable error was too boring and improbable to follow. She turns out to be some kind of ex-CIA assassin so my theory is this: Mary is very short-sighted and forgetful, so at the critical moment she simply loses her bearings and shoots the wrong fellow. Happens all the time.

At least it explains why the CIA might have wished to get rid of her. Judging by her performance last night, even St Obama would be in considerable danger with her around.

How Mary gains entrance to the blackmailer's almost impregnable hi-tech lair is a minor mystery too. Sherlock goes to all the trouble and incongruity of seducing the blackmailer's assistant, while Mary apparently uses the tradesman’s entrance which Sherlock overlooks in the sheer complexity of his thinking.

Sherlock’s delightfully aloof brother Mycroft appears, sneers and disappears throughout. He's rather good at sneering too – it's almost worth watching for that alone.

Mycroft Holmes - from the BBC
In my view, the BBC should go the whole hog and give Sherlock the ability to fly like Superman. Maybe a bionic eye and a bionic ear would add to the drama. The eye and ear could be designed and fitted by Dr Watson and Mary at a top secret MI5 research lab in Hinckley.

Mary would need a quick visit to Specsavers first though. Maybe the gun could be put in a safe place too.

This would bring Sherlock closer to his real mentors such as Batman and Superman. After all, right at the end we are told that boy wonder Moriarty has taken control of all electronic displays in order to broadcast his evil leer to the whole country. Petrifying stuff, but didn’t Lex Luthor try that?
