Big thanks to John H. for forwarding this to me.

Sit back and relax.

Nothing more except to wish everyone, wherever you are, a peaceful week-end, above or below the surface of the ocean!

Please indulge me with this purely personal reflection.

My Uncle Peter died in his sleep at 1.30am UK time on Monday, the 21st May, 2012.  He was 91 and had been suffering from declining health for a while.

As my parting gift from across the seas, I just wanted to record the great inspiration that he was to both me and my son, Alex.

Peter was a great gliding fan (sailplane in American speak!).  He must have started gliding not many years after the end of the war in 1945.  Anyway, when I was a young lad, back in the mists of time, my Uncle Peter took me for a glider flight.  That left a memory in me that lay dormant for many years until the late 1970s when a colleague, Roger Davis, introduced me to the Rattlesden Gliding Club and that started a 25-year interest in gliding and later power flying.

My son, Alex, also when he was a young boy was taken up for his first flight in a glider by Uncle Peter and later flew with me many times both in gliders and power aircraft.  Today he is a Senior Captain with a British airline.

So, dear Uncle Peter, what an aviation inspiration you have been for two generations.

Uncle Peter and two generations of pilots.

As it happens, 1.30 am UK time on Monday the 21st was 5.30pm Arizonan time on Sunday the 20th.  At that very moment, well 5.26pm to be precise, Jean and I were watching the solar eclipse and I took the photograph below of what was the partial eclipse here in Payson.

A tribute to a wonderful family man with a great sense of humour.

Center for American Progress Action Fund plea to all Americans

Friends,

For the first time in history, the Environmental Protection Agency has proposed to limit industrial carbon pollution from new power plants. This important action will slow the growth of the major pollutant responsible for global climate change. These new limits will have far-reaching public health impacts.

It’s up to all of us to demonstrate strong public demand for clean air: Make your voice heard now in support of carbon pollution limits for new and existing power plants. 

Power plants dump more than two billion tons of carbon and other toxic pollutants into the air each year—nearly 13,000 pounds for every man, woman, and child in the United States. With the proposed standard, though, a typical new coal-fired power plant would have to reduce its carbon pollution by 40 percent to 60 percent. Natural gas power plants should be able to comply with this standard without additional controls.

President Barack Obama has endorsed limits on carbon pollution from motor vehicles, which will ultimately reduce tailpipe emissions by six billion metric tons over the life of the program.

More than 120 health organizations have urged the government to reduce “the threat to public health posed by climate change and to support measures that will reduce these risks.” These health groups include the American Lung Association, American Public Health Association, American Thoracic Society, and others.

I proudly served as the administrator of the Environmental Protection Agency for eight years, and I know from experience how vitally important it is that citizens who support proposed public health standards that reduce pollution make their voices heard. Certainly, many of the companies emitting the pollution and other interests that oppose clean air standards will do so.

During the first month available for public comments, more than one million Americans took action to express their support for cleaner air, but we need your voice today!

Will you join us and more than one million Americans calling for cleaner air? Make your voice heard—click here to submit a favorable comment to the Environmental Protection Agency today! Thanks again! 

Sincerely,

Carol M. Browner
Distinguished Senior Fellow, Center for American Progress Action Fund

Coal-fired power damages health and the environment

Coal-fired power generation damages people’s health and contributes to climate change, according to a new study by academics at the University of Pretoria.

The study shows how coal-fired power stations run up large costs as a result of coincidental but often unavoidable side-effects electricity generation.

These ‘externalities’ include the creation of carbon dioxide, carbon monoxide, methane, oxides of nitrogen, sulphur oxide, mercury and a wide range of carcinogenic radio-nuclides and heavy metals during the combustion process.

The Business Enterprises department of the University of Pretoria conducted the study for Greenpeace Africa and Greenpeace International at Kusile power station in Emalahleni in September 2011.

According to the report: “In the generation of coal-fire power, the objective is electricity production, yet, as a side effect, emissions are also produced.

“Various epidemiological studies found that the mentioned pollutants contribute to the incidence of mortality.”

The study also measures the cost to the environment by determining the amount of potentially damaging emissions from a power station.

According to the report, Kusile power station emits 30m tons of carbon dioxide per year, on an annual consumption of 17m tons of coal.

The analysis provides strong evidence of the need for Eskom, the largest energy provider in Africa, to invest in alternative renewable energy sources and for the government to support such investment initiatives.

But Eskom is building more coal-fired power stations to add to new power stations in Kusile and Medupi in Lephalale, Limpopo, with the support of the Department of Energy.

Building new power plants also requires the construction of new coal mines and the expansion of existing coal mines.

There are fears that coal fired power plants like Kusile in South could severely contribute to climate change.

Just re-read that sentence above that spoke of Kusile power station, “Kusile power station emits 30m tons of carbon dioxide per year, on an annual consumption of 17m tons of coal.“

So, please, if you are an American who cares for the future of your children and grandchildren, take action.

Our fate is also wrapped up in the ocean – another cause for tears.

In a very real sense, this Post continues from my writings of yesterday concerning James Hansen.

A year ago, the BBC reported the shocking state of our oceans.  It included this:

“The rate of change is vastly exceeding what we were expecting even a couple of years ago,” said Ove Hoegh-Guldberg, a coral specialist from the University of Queensland in Australia.

“So if you look at almost everything, whether it’s fisheries in temperate zones or coral reefs or Arctic sea ice, all of this is undergoing changes, but at a much faster rate than we had thought.”

But more worrying than this, the team noted, are the ways in which different issues act synergistically to increase threats to marine life.

Some pollutants, for example, stick to the surfaces of tiny plastic particles that are now found in the ocean bed.

This increases the amounts of these pollutants that are consumed by bottom-feeding fish.

Plastic particles also assist the transport of algae from place to place, increasing the occurrence of toxic algal blooms – which are also caused by the influx of nutrient-rich pollution from agricultural land.

In a wider sense, ocean acidification, warming, local pollution and overfishing are acting together to increase the threat to coral reefs – so much so that three-quarters of the world’s reefs are at risk of severe decline.

As Callum Roberts explains in a forthcoming book The Ocean of Life,

Prof. Callum Roberts

We have always been fish eaters, from the dawn of civilization, but in the last twenty years we have transformed the oceans beyond recognition. Putting our exploitation of the seas into historical context, Roberts offers a devastating account of the impact of modern fishing techniques, pollution, and climate change, and reveals what it would take to steer the right course while there is still time. Like Four Fish and The Omnivore’s Dilemma, The Ocean of Life takes a long view to tell a story in which each one of us has a role to play.

That book was recently reviewed in The Economist, from which I reproduce the following extracts,

The Ocean of Life: The Fate of Man and the Sea. By Callum Roberts.

Traditional attitudes towards the sea, as something immutable and distant to humanity, are hugely out of date. The temperature change that harmed the corals was not caused by human activity; yet it was a foretaste of what man is now doing to the sea. The effects of overfishing, agricultural pollution and anthropogenic climate change, acting in concert, are devastating marine ecosystems. Though corals are returning to many reefs, there is a fair chance that in just a few decades they will all be destroyed, as ocean temperatures rise owing to global warming. The industrial pollution that is cooking the climate could also cause another problem: carbon dioxide, absorbed by the sea from the atmosphere, turns to carbonic acid, which is a threat to coral, mussels, oysters and any creature with a shell of calcium carbonate.

The reviewer explains that, “The enormity of the sea’s troubles, and their implications for mankind, are mind-boggling. Yet it is equally remarkable how little this is recognised by policymakers—let alone the general public.” and then adds, to the author’s credit, ” There is also a dearth of good and comprehensive books on a subject that can seem too complicated and depressing for any single tome. Callum Roberts, a conservation biologist, has now provided one.”

The book review then continues,

He [Callum Roberts] starts with a bold claim: that anthropogenic stresses are changing the oceans faster than at almost any time in the planet’s history. That may be putting it too strongly. Yet there is no quibbling with the evidence of marine horrors that Mr Roberts presents.

Take overfishing. The industrialisation of fishing fleets has massively increased man’s capability to scoop protein from the deep. An estimated area equivalent to half the world’s continental shelves is trawled every year, including by vast factory ships able to put to sea for weeks on end. Yet what they are scraping is the bottom of the barrel: most commercial species have been reduced by over 75% and some, like whitetip sharks and common skate, by 99%. For all the marvellous improvements in technology, British fishermen, mostly using sail-power, caught more than twice as much cod, haddock and plaice in the 1880s as they do today. By one estimate, for every hour of fishing, with electronic sonar fish finders and industrial winches, dredges and nets, they catch 6% of what their forebears caught 120 year ago.

Overfishing is eradicating the primary protein source of one in five people, many of them poor. It also weakens marine ecosystems, making them even more vulnerable to big changes coming downstream.

For example, there is the matter of chemical pollution, mostly from agricultural run-off. This has created over 400 dead-zones, where algal tides turn the sea anoxic for all or part of the year. One of the biggest, at the mouth of the Mississippi Delta in the Gulf of Mexico, covers 20,000 square km (7,700 square miles) of ocean. An annual event, mainly caused by the run-off of agricultural fertilisers from 40% of America’s lower 48 states, it makes the one-off Deepwater Horizon oil-spill look modest by comparison.

Global warming is another problem. Hitherto, the sea has been a buffer against it: because the heat capacity of water is several times that of air, the oceans have sucked up most of the additional heat, sparing the continents further warming. Yet this is now starting to change—faster than almost anyone had dared imagine.

One effect of the warming ocean, for example, is to increase the density difference between the surface and the chilly deep, which in turn decreases mixing of them. That means less oxygen is making it down to the depths, reducing the liveability of the oceans. Off America’s west coast, the upper limit of low-oxygen water is thought to have risen by 100 metres. Where strong winds bring this water nearer to the surface, there are mass die-offs of marine life. Such events will proliferate as the climate warms.

This is a poor lookout for already put-upon fish. “Fish under temperature and oxygen stress will reach smaller sizes, live less long and will have to devote a bigger fraction of their energy to survival at the cost of growth and reproduction,” writes Mr Roberts. And that is before he gets to the effects of ocean acidification, which could be very bad indeed. Without dramatic action to reverse these processes, he predicts a catastrophe comparable to the mass extinctions of the Palaeocene-Eocene Thermal Maximum, when carbon-dioxide levels, temperature and ocean acidity all rocketed. He writes: “Not for 55m years has there been oceanic disruption of comparable severity to the calamity that lies just a hundred years ahead.” That would be hard to prove; it would be better not to try.

So what is to be done? Mr Roberts provides a hundred pages of answers, occupying roughly a third of the book. They range from the obvious—curbing carbon emissions—to technical fixes, like genetic improvements to aquaculture stocks. None is impossible; and Mr Roberts, almost incredibly, describes himself as an optimist. He writes, “We can change. We can turn around our impacts on the biosphere.” We had better do so.

Amen to that!

So want to know where to start?  Here’s a snippet of advice in terms of protecting our fish stocks,

Free speech isn’t always free!

Recently over at the Blog Climate Sight, Kate wrote a Post about the antics of the group known as the  Heartland Institute, a Chicago-based PR group that denies the existence of human-caused climate change. Kate has given me permission to reproduce her post in full.

Stalin believed in gravity. Do you?

May 9, 2012 by climatesight

Here’s a classy way to slam people you disagree with: compare them to terrorists, dictators, and mass murderers.

Such was the focus of a recent billboard campaign by the Chicago-based Heartland Institute, a PR group that denies the existence of human-caused climate change. The only billboard that was actually displayed featured Ted Kaczynski (the Unabomber) and read, “I still believe in global warming. Do you?”

The message is clear: if a monster believes something, citizens of good moral standing should believe exactly the opposite. The Internet was quick to ridicule this philosophy, with parodies such as the following:

Similar billboards featuring Charles Manson and Fidel Castro were planned, but never publicly displayed. Heartland also considered putting Osama bin Laden on a future billboard. On their website, they attempted to justify this campaign:

The people who still believe in man-made global warming are mostly on the radical fringe of society. This is why the most prominent advocates of global warming aren’t scientists. They are murderers, tyrants, and madmen.

Given that a majority of Americans accept global warming, people did not take kindly to this campaign. Public outcry and negative media coverage led Heartland to cancel the project after 24 hours. However, their statementshowed little remorse:

We do not apologize for running the ad, and we will continue to experiment with ways to communicate the ‘realist’ message on the climate.

Even though the campaign has been cancelled, the Heartland Institute continues to suffer financial repercussions. Dozens of corporate donors, including State Farm Insurance and drinks firm Diego (which owns Guiness and Smirnoff) have ended their support as a direct result of this campaign. Earlier in the year, Heartland lost financial backing from General Motors after internal documents exposed some of the group’s projects, particularly the development of an alternative curriculum to teach K-12 students that global warming is fake.

Will they recover from this failed campaign? Given Heartland’s reliance on donations, their prospects look poor. It seems that the Heartland Institute, previously one of the most influential mouthpieces for climate change denial, is going out with a bang.

My prayer is that the aforementioned institute goes out, not with a bang, but with the sound of whimpering!  Because the right of free speech is abused and shamed by such disgraceful actions.  Well done, Kate.

Some of life’s lessons are easy to learn – once we have been taught!

Readers be warned!  This is one of my more subjective posts written in the hope that many will ‘connect’ with the emotions expressed.

Learning touch from Casey

I want to explore the power of touch.

Not just in a direct manner such as a hug or an arm around the shoulder but also the way that love can reach out and ‘touch’ us from afar.  I’m going to do that by recounting something that Jean and I have experienced over the last couple of weeks.  Here we go!

A while after we had moved to Payson in February, 2010 both Jean and I noticed that I was getting forgetful. Initially we thought it was just a characteristic of the vestibular migraine that I was diagnosed with in 2009 but eventually it seemed a good idea to have a local doctor here in Payson check me out.  That examination took place last April 24th., a little over two weeks ago.  The doctor dropped a huge bombshell in our laps by saying that she thought that I was exhibiting signs of early-onset Alzheimer’s Disease!

To say that I was shocked was an understatement.  Jean was beside herself with worry as her late American husband, who had died in 2005, had suffered badly from Alzheimer’s Disease for his last two years.  We had 48-hours of wall-to-wall worry!

A few days later, I was getting very angry at the lack of gentleness in the way that the doctor had spoken to me.  Jean had the brilliant idea of contacting a retired doctor friend.  His response was loud and clear; he advised me to get a second opinion and continued by recommending a neurologist that he knew well.  That appointment was held this last Tuesday, May 8th, down in Phoenix.

The neurologist asked me many questions, including such verbal tests as how many animals can you name in a minute, spell the word ‘world’ backwards, deduct 7 from 95 (and then keep deducting 7 from the resultant answer!!), and then undertook a physical examination including co-ordination skills, blood flow in the neck and other relevant aspects.

All of which lead him to the conclusion that I was not showing any signs of dementia.  My forgetfulness was normal for someone of my age (67 last birthday) especially taking into account all the life changes of the past few years.

Then the neurologist went on to warn me about anxiety.  He said it was a ‘killer’ of healthy bodies and healthy minds, especially as we got older.  So my anxiety over my sister’s dementia, my half-sister living in Devon, England, whom I am very close to, is now badly affected by vascular dementia and got me thinking I might be following in her path, and my anxiety over thinking my life now was ‘too good to be true’, was getting in the way of me being a relaxed, ‘go with the flow’ individual.

Thus a couple of extremely stressful and worrying weeks came to a most wonderful conclusion; an outcome that couldn’t have been better.  The degree of emotional and psychological disruption that Jean and I have been through was not however without some major lessons being learnt.

Being scared – I’ve always taken for granted that I would have good health throughout my life, aided and abetted by the fact that I have never been admitted to hospital and have avoided serious illnesses.  The first doctor’s so-called diagnosis was one giant slap-in-the-face especially realising that the future in store could be a steady decline in my cognitive skills.

For the first time in my life I was truly scared and last Monday, the day before the visit to the neurologist, I broke down in Jean’s arms saying how scared I was.  Revealing such vulnerability was not easy for me but being held by Jean under those circumstances was deep and pure bliss.  As the saying goes, ‘If one doesn’t run the risk of being lost, then one can never be found.’

Love and friendship – The number of people that came up to Jean and me, gave us big hugs and said that they would be thinking of us during our trip down to Phoenix last Tuesday was indescribably beautiful.  So many showed such a depth of feeling for what Jean and I were going through.  Many others from distant places sent encouraging emails or telephoned.  It all amounted to preventing us from feeling alone and reinforced our determination that whatever the medical outcome, we would find a way of handling it.

The power of the mind – my brother-in-law, in a recent telephone call, said that once the mind latches on to an idea, it does everything it can to reinforce that idea, however illogical it may be.  Thus over the last couple of weeks, every time I dropped something, or forgot where I had put my glasses, or wasn’t clear which day of the week it was, and on and on, I used that as ‘proof’ that I was rapidly losing my mind.  It should serve as a strong warning that we can literally think ourselves into a crisis!

The love between a dog and a human – hugging a dog when one is feeling emotionally vulnerable is beyond measure.  Dogs always sense when we humans are feeling fragile and they offer their uncomplicated hearts to us without any condition or need for return.  That selfless love is an inspiring example of what we all need to learn to give one another.

Touch and social intimacy – we have so much to learn from dogs when it comes to touch and social intimacy.   We are all needy for touch.

Which leads me providentially to a recent item from Terry Hershey.  Terry came to Payson in March, 2011 and he was a most inspirational speaker.  I have followed him ever since.

Last Monday’s Sabbath Moment included the following story, republished with Terry’s kind permission – the story is all about touch!

Caroline was very sad. Caroline was only six years old and her father had just died. In fact, her father had been assassinated.

Sitting in the back of big black limousine, Caroline Kennedy didn’t quite know what to do with her sadness. On the seat next to her sat her nanny, Maud Shaw, and next to Maud, Caroline’s younger brother John.

Through the windshield Caroline could see her mother, Jackie, and her uncles, Robert and Ted, walking in front of the limousine as it slowly made it’s way down the Boulevard to St. Matthew’s Cathedral.  Looking out of her side of the car, Caroline recognized the friendly face of Secret Service agent, Robert Foster. She liked and trusted Robert Foster.

Not knowing what to do with her sadness, and on impulse, she rolled down the window and stuck out her six-year old hand. Agent Foster had a choice to make. Secret Service agents are not allowed to have their hands occupied, needing to be ready for any emergency. But Robert Foster didn’t even think twice. He held Caroline’s hand tightly the entire way to the cathedral.

Later, Agent Foster said it was all he could do to “fight back his own tears of sadness, for little Caroline Kennedy.” When asked about his kindness, he seemed surprised, “All I did was hold a hand,” he answered.

Terry then goes on to say,

We all know sadness. Life breaks for each one of us in different ways and in different places. And sometimes the sadness seems too much to carry.

It requires courage to roll down the window, to connect or ask or invite. For whatever reason, there is a knee-jerk need to deny any sadness, or dismiss it, or apologize for it. “I’m sorry,” people will say, wiping away their tears, as if their sadness is a violation of some tenet of propriety. Heaven forbid if any humanity is exposed.

So sometimes I am afraid to ask. Not sometimes; most times. I don’t want to appear weak. Asking for help is a hard pill to swallow.

I spent Saturday in Clearwater, Florida, with a group talking about intimacy and communication. (Yes, it is easier to talk about than to practice.)  Here’s what I told the group.

If we don’t bring it with us, we’re not going to find it there.  Which means intimacy–trust, vulnerability, authenticity, honesty–begins here.

With me. With this me.

I was raised in a religious environment that taught me to eradicate my messiness (to quash my sadness or grief or untidiness).

I now believe differently. I now know that we find and express acceptance, love and grace (the place where we can be fully human), in our messy, imperfect, and fully thorny selves. In other words: We can embrace this life–without any need to photoshop it.

To be human is to be vulnerable.  I am capable of being wounded and cut and sad… which also means that I am capable of being kind and generous and present.

In such moments of heartache, I can have the courage to ask for a hand to hold.

In such moments of heartache, I can have the courage to hold a hand the needs to be held.

Robert Foster didn’t think twice about holding a hand that needed to be held. And he wasn’t posturing or amassing heavenly brownie points. He was doing what needed to be done.

Here’s the deal: we don’t need more remedies or advice. We need more touch. We become more human when we touch. Why? Because when we touch, we are seen.  And when we are seen, we recognize that our value is not tied solely to our sorrow.

And we, you and I, will find no better lesson to learn from our beautiful canine friends, than this lesson of touch.

The loving touch of a dog.

Biggest full moon of 2012 occurs today!*

There are a number of news stories about this extra-special full moon but I’ve chosen to republish some of what appeared on the Mother Nature Network website.

In terms of the timing of this full moon, rather than give you times for various places around the world, as this website does, I will simply offer the UTC/GMT time:

Sunday 6th May 2012 at 03:35:06 am

If you want to covert that to your local time wherever you are on this beautiful planet The World Time Server is as good a website as any.

BIGGER THAN YOUR AVERAGE MOON: Skywatcher Tim McCord of Entiat, Washington caught this amazing view of the March 19, 2011 supermoon. (Photo: Tim McCord)

Skywatchers take note: The biggest full moon of the year is due to arrive this weekend.  And because this month’s full moon coincides with the moon’s perigee — its closest approach to Earth — it will also be the year’s biggest.

The moon will swing in 221,802 miles (356,955 kilometers) from our planet, offering skywatchers a spectacular view of an extra-big, extra-bright moon, nicknamed a supermoon.

And not only does the moon’s perigee coincide with full moon this month, but this perigee will be the nearest to Earth of any this year, as the distance of the moon’s close approach varies by about 3 percent, according to meteorologist Joe Rao, SPACE.com’s skywatching columnist. This happens because the moon’s orbit is not perfectly circular.

The full Moon will be up to 14% larger and 30% brighter than others during the year. The reason for this phenomenon is that the Moon becomes full on its closest approach to Earth on May 5, 2012, also known as the perigee full Moon.

So enjoy this most beautiful sight if you are somewhere on this planet where the moon will be visible at night.  And double-check the time and the day so you don’t miss it!  Finally, let me close by ‘spoiling’ my many readers in Arizona, and to serve as a good reminder for yours truly by saying that anyone on US Mountain Standard Time will see this moon at:

“Aim for the moon. If you miss, you may hit a star.” W. Clement Stone.

“Exact knowledge is the enemy of vitalism.” Francis Crick.

On the face of it, I’m going to write about two totally disparate aspects of the brain.  Or are they?

I subscribe to Naked Capitalism and one of my favourite aspects of Yves’s daily email presentation are the Links.  They cover an incredibly broad range of news items.

So it was perhaps a week ago or thereabouts that one of those links was to an item in the British newspaper, The Daily Mail.  Here’s how the article started,

Power really does corrupt as scientists claim it’s as addictive as cocaine

More than a hundred years after noted historian Baron John Acton coined the phrase ‘power tends to corrupt, and absolute power corrupts absolutely’ scientists claim the saying is biologically true.

The feeling of power has been found to have a similar effect on the brain to cocaine by increasing the levels of testosterone and its by-product 3-androstanediol in both men and women.

This in turn leads to raised levels of dopamine, the brain’s reward system called the nucleus accumbens, which can be very addictive.

Across in the English paper The Daily Telegraph, Dr Ian Robertson writes on this subject and says,

Unfettered power has almost identical effects, but in the light of yesterday’s Leveson Inquiry interchanges in London, there seems to be less chance of British government ministers becoming addicted to power. Why? Because, as it appears from the emails released by James Murdoch yesterday, they appeared to be submissive to the all-powerful Murdoch empire, hugely dependent on the support of this organization for their jobs and status, who could swing hundreds of thousands of votes for or against them.

Submissiveness and dominance have their effects on the same reward circuits of the brain as power and cocaine. Baboons low down in the dominance hierarchy have lower levels of dopamine in key brain areas, but if they get ‘promoted’ to a higher position, then dopamine rises accordingly. This makes them more aggressive and sexually active, and in humans similar changes happen when people are given power. What’s more, power also makes people smarter, because dopamine improves the functioning of the brain’s frontal lobes. Conversely, demotion in a hierarchy decreases dopamine levels, increases stress and reduces cognitive function.

OK, moving on.  On April 29th., there was an article on the Big Think website with the intriguing title of You Are Not Your Brain! 

What’s the Big Idea?

“Contemporary research on consciousness in neuroscience rests on unquestioned but highly questionable foundations. Human nature is no less mysterious now than it was a hundred years ago,” writes philosopher Alva Noë in his book Out of Our Heads.

It’s a bold assertion in an age when fMRI has enabled us to see images of the brain functioning in real time, and when many prominent public intellectuals (Stephen Hawking, Eric Kandel) have argued, either implicitly or vociferously, in favor of reductionism. The “brain-as-calculating machine” analogy assumes that human thought, personality, memory, and emotion are located somewhere in the gray matter protected by the skull. In other words, you – at least, the waking you who gets out of bed in the morning – are your brain.

But you’re not, says Noë. Just as love does not live inside the heart, consciousness is not contained in a finite space — it’s something that arises, something that occurs: a verb rather than a noun. And since the publication of Francis Crick’s influential The Astonishing Hypothesis: The Scientific Search for the Soul, scientists have been looking for it in all the wrong places.

That’s enough of me republishing the article – if it grabs your interest, do go and read it in full here.

And here’s Francis Crick with an extract from his DVD on the Scientific Search for the Soul

NOTE: This is an excerpt from the two-part, 60-minute DVD.
http://www.thinkingallowed.com/2fcrick.html

A noted scientist discusses free will, consciousness, attention and memory and their relationship to the human nervous system. In a wide ranging discussion, Crick points out that the hypothesis that the brain is the seat of consciousness has not yet been proven.

Francis Crick, Ph.D., received the Nobel Prize in 1962 for the discovery of DNA’s central role in the process of genetic reproduction. He is author of Life Itself, What Mad Pursuit and The Astonishing Hypothesis.

“Chance is the only source of true novelty.” Francis Crick

Sometimes one wonders what happened to common sense!

Today’s Post is motivated by a number of items that have crossed my screen over the last few days which when looked at collectively might remind one of the old saw, “You don’t have to be mad to work here, but it does help!“

Sit with me, metaphorically, and allow me to muse.

First was a recent Post on 350 or bust that included the March 2012 TED Conference in Long Beach, California where NASA climate scientist Dr. James Hansen explains why he must speak out about climate change. (See the video later on.)  That Post refers to an item on Martin Lack’s Blog, Lack of Environment, where Martin as well as including the video below also lists the challenges that we on this single, finite planet face.  Here is that list,

1. The Earth’s current energy imbalance is 0.6 Watts per sq.m.; a rate of energy input 20 times greater than the energy output of all human activity; and equivalent to the detonation of 400,000 Hiroshima-type atomic bombs every day.
2. Since measurements began in 2003, there has been a noticeable acceleration in the annual rate of mass loss from both the Greenland and Antarctica ice caps.
3. The last time atmospheric CO2 was 390 ppm, sea levels were 15 m higher than they are today, which implies even if we stopped burning all fossil fuels tomorrow, this is where they would end up several centuries from now because the warming “is already in the pipeline” (i.e. because the Earth must warm-up in order to restore its energy balance).
4. Unless we stop burning fossil fuels soon, sea level rise will continue to accelerate, which is likely to cause between 1 and 5 metre rise by 2100AD (depending on how quickly we now decide to stop burning them).
5. Palaeoclimatology tells us that 350 ppm is the safe limit for avoiding significant disruption to the planet’s ecological carrying capacity (i.e. in terms of both populations of individual species and overall biodivesity); and it now seems likely that between 20%-50% of all species will be “ticketed for extinction” by the end of the century.
6. If we push the Earth beyond it’s “tipping point” (i.e. allow all the emerging positive feedback mechanisms to take hold); ACD will become unstoppable; and the ensuing socio-economic damage will be almost unimaginable. The total global cost of mitigation is already put at somewhere between 35 and 70 Trillion US Dollars depending on how soon we choose to act.
7. If we had started to get off fossil fuels in 2005, it would have required 3% reduction per year in order to restore energy imbalance by 2100AD. If we start next year, it will require 6% p.a. If we wait 10 years it will require 15% p.a.
8. Recent droughts in Texas, Oklahoma and New Mexico were 3 Standard Deviations outside the norm. Events such as these cannot therefore be ascribed to natural variability; anthropogenic climate disruption (ACD) is happening just as Hansen said it would 24 years ago (if we did not change course – which we haven’t).
9. Pursuing emissions limits (i.e. Cap and Trade) will not work because there is no actual incentive to reduce emissions without any self-imposed restraint being to the advantage of others who do not do the same (i.e. the Tragedy of the Commons problem).
10. Hansen uses the analogy of an approaching asteroid – the longer we wait to prevent it hitting us the harder it becomes to do so.

Do watch that Hansen video,

Second is that yesterday Martin Lack published an item that really does seem to endorse the view that there is no sign of intelligent life living on Planet Earth (not counting dogs!).

Think about it.  The planet is warming up.  The use of carbon-based fuels is a strong suspect, putting it mildly, of the rising levels of CO2 in our atmosphere, 394.45 on April 5th, so rather than change the incentives for using such fuels, we are taking advantage of  this warming planet causing the melt of the Arctic ice cap by allowing Shell to drill for oil in the Arctic.  But even crazier than that, Shell have contracted for a Finnish icebreaker to assist them in breaking up the ice!  (I really do feel a headache coming on!)

Greenpeace in the UK are running a campaign to stop this.

Sign up to save the Arctic

Let Shell know your feelings.

The pristine and beautiful Arctic: Shell wants to exploit it for oil. We want it protected.

Dozens of Greenpeace Nordic activists have boarded and occupied a Shell-contracted icebreaker in Helsinki harbour as it prepares to leave for the Alaskan Arctic.

Drilling in this fragile ecosystem – home to the polar bear, narwhal, Arctic fox and other iconic species – is unacceptable. A spill or accident in these waters would be disastrous and the harsh conditions would make responding to such a disaster almost impossible.

Demand Shell stop their plans to put the fragile Arctic and its biodiversity at risk.  We’ll keep you updated on our campaigns.

Write to Mr. Peter Voser.

Mr Peter Voser, Shell

The Arctic isn’t a place you can exploit, it’s a place we have to protect. Time and time again, experts have expressed serious doubts about the possibility of cleaning up an oil spill in the Arctic. The technical challenges posed by drilling there are obvious and no matter how much you try to convince people that your company can operate safely in such a harsh environment, we know the truth.

Because of this, I demand that you scrap your Arctic plans immediately.

Yours sincerely,

By the end of this week we want 500,000 people shouting at Shell that it must end its campaign of Arctic destruction. Click here now. [N.B. This is a time-sensitive campaign response - please visit Greenpeace website and enter your name and email address and they will email Shell on your behalf.]

We can change things! Together we can stop Shell and other oil companies from destroying the Arctic. Not everyone can board a ship to demand that change. But today, you can email Shell and ask them to stop drilling for oil and ask 10 of your friends to do the same. Together, we can save the Arctic!

It’s not just an isolated instance of madness! Just a little over 10 days ago, I reported on President Obama’s support for the oil companies that threatens the polar bears, see “President Obama’s proposal for these magnificent and imperiled animals is a gift to Big Oil”

In closing, luckily there are many voices being raised about putting an end to this madness; see the recent item from Patrice Ayme.  Hopefully, all these voices will bring about the changes to the way so many of us are governed.  As Patrice commented recently on Learning from Dogs, “Hope is the breathing of the planet“.  Maybe, just maybe, hope will win through.  No better put than by James Hansen,

Most impressive is the work of the Citizens Climate Lobby, a relatively new, fastgrowing, nonpartisan, nonprofit group with 46 chapters across the United States and Canada. If you want to join the fight to save the planet, to save creation for your grandchildren, there is no more effective step you could take than becoming an active member of this group.”

Oh, and before I forget, a tornado touched down in Southern France!  Not common and not making sense!

Some milestones on the age of the solar system.

Forgive me, dear readers, but something light and simple for today.  I don’t mean in the sense of the content, far from it, just easy for me to put the post together as it is from a presentation that I gave a year ago.

Here’s a picture of our solar system.

Most of us are reasonably familiar with this visual concept of our solar system, but what of it’s age?  That’s much more difficult to embrace in a way that we can relate to.

So let’s use something to represent the age of our solar system, the distance from Phoenix to Payson.

In round terms, Payson is 80 miles North-East from Phoenix.  Put another way, that’s 422,400 feet!

So if those 80 miles represented the age of our solar system, what would be the significant milestones on this metaphorical journey?

Phoenix represents the start, the ‘start’ of our solar system some 4.54 billion years ago

It was 1,075,000,000 years before Blue-green algae appeared.  That is the equivalent of travelling 18.94 miles from Phoenix North-East along Highway 87.  Or looking back, those algae appeared some 3.465 billion years ago.

But on we travel, metaphorically an unimaginable 3,459,800,000 years after the arrival of Blue-green algae until the next milestone; the earliest hominids.  In terms of our Highway that’s a further 60.97 miles.  Again, looking back that was 5,200,000 years ago.

The sharp-eyed among you will see that 18.94 miles added to 60.97 miles is 79.91 miles.  Goodness that’s awfully close to the total distance of 80 miles between Phoenix and Payson!  In fact, the 0.09 miles to run is the equivalent of 484 feet!

So let’s look at those last 484 feet.

The first 465.20 feet represents the approximately 5 million years after the earliest hominids appeared before H. sapiens arrived, some 200,000 years ago.

The appearance of Homo sapiens brings us to just 18.6 feet from Payson.

But first, we travel 9.3 feet and see the arrival of dogs, generally regarded to have separated, in DNA terms, from the Grey Wolf 100,000 years ago.

And are you 60 years old?  You were born just 0.0669 inches or 7/100ths of an inch from Payson!  If my maths is correct (someone please check!) 0.0669 inches is about 34 times the thickness of the human hair!  That’s very close to Payson!

Don’t know about you but it puts the age of our solar system into a perspective one might be able to get one’s arms around.

On the scale used above, one inch represents 895.68 years, one foot the equivalent of 10,748.11 years and a mile represents 56,750,000 years.

Anybody want to hazard a guess as to the state of our planet in one further inch?

The difference an inch makes! 895.68 years!

OK, let me stay more or less on topic and just round things off.

EarthSky website seems to have some great items, including this one.

Ten things you may not know about the solar system

9 ) Pluto is smaller than the USA
The greatest distance across the contiguous United States is nearly 2,900 miles (from Northern California to Maine). By the best current estimates, Pluto is just over 1400 miles across, less than half the width of the U.S. Certainly in size it is much smaller than any major planet, perhaps making it a bit easier to understand why a few years ago it was “demoted” from full planet status. It is now known as a “dwarf planet.”

Go here for the full list of ten items.

Finally, just how far does it all go?

How far do the stars stretch out into space? And what’s beyond them? In modern times, we built giant telescopes that have allowed us to cast our gaze deep into the universe. Astronomers have been able to look back to near the time of its birth. They’ve reconstructed the course of cosmic history in astonishing detail.

From intensive computer modeling, and myriad close observations, they’ve uncovered important clues to its ongoing evolution. Many now conclude that what we can see, the stars and galaxies that stretch out to the limits of our vision, represent only a small fraction of all there is.

Does the universe go on forever? Where do we fit within it? And how would the great thinkers have wrapped their brains around the far-out ideas on today’s cutting edge?

For those who find infinity hard to grasp, even troubling, you’re not alone. It’s a concept that has long tormented even the best minds.

Over two thousand years ago, the Greek mathematician Pythagoras and his followers saw numerical relationships as the key to understanding the world around them.

But in their investigation of geometric shapes, they discovered that some important ratios could not be expressed in simple numbers.

Take the circumference of a circle to its diameter, called Pi.

Computer scientists recently calculated Pi to 5 trillion digits, confirming what the Greeks learned: there are no repeating patterns and no ending in sight.

The discovery of the so-called irrational numbers like Pi was so disturbing, legend has it, that one member of the Pythagorian cult, Hippassus, was drowned at sea for divulging their existence.

A century later, the philosopher Zeno brought infinity into the open with a series of paradoxes: situations that are true, but strongly counter-intuitive.

In this modern update of one of Zeno’s paradoxes, say you have arrived at an intersection. But you are only allowed to cross the street in increments of half the distance to the other side. So to cross this finite distance, you must take an infinite number of steps.

In math today, it’s a given that you can subdivide any length an infinite number of times, or find an infinity of points along a line.

What made the idea of infinity so troubling to the Greeks is that it clashed with their goal of using numbers to explain the workings of the real world.

To the philosopher Aristotle, a century after Zeno, infinity evoked the formless chaos from which the world was thought to have emerged: a primordial state with no natural laws or limits, devoid of all form and content.

But if the universe is finite, what would happen if a warrior traveled to the edge and tossed a spear? Where would it go?

It would not fly off on an infinite journey, Aristotle said. Rather, it would join the motion of the stars in a crystalline sphere that encircled the Earth. To preserve the idea of a limited universe, Aristotle would craft an historic distinction.

On the one hand, Aristotle pointed to the irrational numbers such as Pi. Each new calculation results in an additional digit, but the final, final number in the string can never be specified. So Aristotle called it “potentially” infinite.

Then there’s the “actually infinite,” like the total number of points or subdivisions along a line. It’s literally uncountable. Aristotle reserved the status of “actually infinite” for the so-called “prime mover” that created the world and is beyond our capacity to understand. This became the basis for what’s called the Cosmological, or First Cause, argument for the existence of God.

Think I need to lie down now!
