Perhaps ancient man is still alive and well in all of us.
Two delightful events have provided the fuel for today’s post which, I warn you, is much more the personal mental ramble than the usual daily post on Learning from Dogs. So, health warning, continue reading at your own risk, or be safe and switch off now!
Before getting in to my perambulations, just a word of thanks to you for your support. Last month, there were 31,291 viewers of Learning from Dogs and 71 of you have chosen to subscribe. I am humbled by your interest. Don’t ever hesitate to give me feedback or, if you prefer, comment to a specific post.
OK, to the theme of today.
On Wednesday I had an enjoyable lunch with a friend from here in Payson, Dennis L. Sitting in the Crosswinds restaurant at Payson airport is one of the most beautiful eating spots in terms of the view from the window. So it’s a very conducive place to relax and try put the world to rights! Conversation ranged across a variety of topics but frequently touched on the lunacy of so many things to do with man, especially when it comes to the government of peoples.
Dennis and I also acknowledged that entering politics with a set of passionate ideals, as we were sure many persons did, would quickly run up against the skein of vested interests that must permeate governments from top to bottom.
Yes Minister was a satirical comedy written by Antony Jay and Jonathan Lynn that ran for many years. It was extraordinarily funny, here’s a 3-minute clip,
That programme underlined, far better than anything else, how governments most probably work in reality.
Dennis and I were clear, as so many millions of other global citizens must be, that the complexity of commerce, politics, national interests, global finance, and more, had created ‘systems’ of decision making that were utterly disconnected with the needs of mankind having a long and stable future on the only finite home around, Planet Earth.
Then today (Thursday), Jean and I attended our regular weekly gardening course at the local college in Payson. Today’s subject was Arizona’s Climate and the tutor, Mike C., was a professional climatologist and meteorologist. It was fascinating, indeed, totally absorbing. Mike’s graphs and slides about the climate, some showing data for the last 1,000 years, underlined the incredible complexity and interconnectedness of the processes that made up the global climate system.
Once again that use of the word ‘complexity’. He confirmed that there was no scientific doubt that the world was warming as a result of changes to the Earth’s atmosphere, science certain most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and burning fossil fuels.
Mike closed the session with an interesting reflection. He reminded the audience that mankind is still essentially wired, in evolutionary terms, to know how to react to an attacking tiger or similar wild beast, as in the fight or flee response, than know how to deal with such complex, despite intellectually obvious, threats as global climate change, rising sea levels and many other totally unsustainable practices. Mike held the view that only when man had the threat in his face equivalent to that of the attacking tiger would there be a wholesale change.
On the home page of this blog, I write,
As man’s companion, protector and helper, history suggests that dogs were critically important in man achieving success as a hunter-gatherer. Dogs ‘teaching’ man to be so successful a hunter enabled evolution, some 20,000 years later, to farming, thence the long journey to modern man. But in the last, say 100 years, that farming spirit has become corrupted to the point where we see the planet’s plant and mineral resources as infinite. Mankind is close to the edge of extinction, literally and spiritually.
In the context of homo sapiens, Latin for “wise man” or “knowing man”, then we know that modern man, anatomically, originated in Africa about 200,000 years ago. Modern man only evolved from hunter/gatherer to farmer around 10,000 years ago, a tiny proportion of H. sapiens existence and, in evolutionary terms, no time at all.
The DNA of the domesticated dog separated from that of the wolf around 100,000 years ago. No one knows for sure when man and dog came together but there is archaeological evidence of dogs being buried in mens’ graves around 30,000 years ago. That’s an association over a huge time period.
Dennis and Mike, between them, triggered in my mind something fundamental. Perhaps modern society, with all it’s bizarre behaviours and so many totally illogical practises (especially, in terms of a long-term relationship with our planet), could be understood. Understood from the perspective of our social behaviours, built so much on technology, having raced far on to the point where they are now practically out of sight of our instinctive evolutionary behaviours. We really don’t know how to change those core behaviours.
In contrast, dogs have remained much more stable with regard to their evolutionary progress and their external world. Consider that the last big change for the domesticated dog was the association with man and that is at least three times as long ago as man becoming farming man. No wonder when we curl up with our dog it has echoes of a time thousands of years before we could even spell the word, ‘politician’. Echoes of a stability that seems now so way beyond reach.
“Have the courage to say no. Have the courage to face the truth. Do the right thing because it is right. These are the magic keys to living your life with integrity.”
The above is attributed to W. Clement Stone, a businessman, philanthropist and author who died in 2002, aged 100. It seemed an appropriate quotation with which to introduce a recent article by Bill McKibben, on the Grist blog, about the proposed Keystone XL pipeline.
Bill McKibben
Keystone pipeline’s last defense: Cold, hard cash
What do you do if you’ve lost an argument?
Say you really really want to build a big pipeline from the tar sands of Alberta so that you can sell your bitumen to the world
But 20 of the nation’s top scientists have written to the president to say it’s a terrible idea — and the planet’s leading climatologist says burning the tar sands would be “game over for the climate.” And nine recent winners of the Nobel Peace Prize have condemned the plan. And Robert Redford has just made a video explaining why the plan is an attack on the nation’s heartland. Then, if you’re a poor forlorn oil industry feeling unloved and under assault, what do you do?
There’s really only one answer: Flash your wad.
As we get to the final chapters of the Keystone pipeline saga (the president has said he’ll make his decision by year’s end), money’s the only argument these guys have left.
They managed to buy a favorable environmental review from the U.S. State Department, which helpfully outsourced the job to a company that was a “major client” of TransCanada, the pipeline builder.
And yesterday, they proposed a $100 million “performance bond” to the state of Nebraska, whose Republican governor and senator have come out against the pipeline. The money is apparently designed to pay for damage to the Ogallala Aquifer if the pipeline starts to leak.
Meanwhile, when 33 Democratic representatives sent a letter to the White House demanding a rejection of the plan, lobbyists for TransCanada rounded up their own list of lawmakers from the president’s party to issue a rejoinder. But they only found 22. And what do you know — they included nine of the top 10 Democratic recipients of oil money in the House. On average the signatories received over 4.25 times more oil money than the average House Democrat in the 112th Congress. That would be 325 percent more. That would be how the game is played.
The other side — that is, scientists, Nobelists, and the kind of average people who went to jail in record numbers this summer to block the plan — doesn’t have that kind of money. We’ve had to figure out other currencies to work in: spirit, passion, creativity. We’ve spent our bodies, putting them on the line. The odds are still against us, but the odds are changing; we’re on a roll as we head toward Nov. 6, when we’ll ring the White House with people, exactly one year before the election. (You can sign up here.)
But every once in a while we get to play the money game too! While TransCanada was out there setting the $100 million price on the Ogallala Aquifer, this news story rolled across my screen. It described a big Democratic giver, Barbarina Heyerdahl. She gave 120 grand to Obama and the Democratic National Committee over the last three years, not to mention knocking on doors for the 2008 campaign. But she said Keystone is a bridge too far, that “she won’t be writing any more checks to Obama if he approves the carbon conduit that’s become the focus of the climate-change movement. ‘It’s a baseline issue,’ she says.”
I have no doubt that, even with Heyerdahl and other donors accounted for, the oil industry has all the money they need to win this fight. The Koch brothers are the third and fourth richest men in America, and they filed papers in Canada declaring their “direct and substantial” interest in the project. If money’s the only thing that matters, they’ll carry the day.
But if money’s the only thing that matters, we’re done for anyway. So we’ll keep using science and art and courage. And we’ll hope that Barack Obama hasn’t sold his soul. We’re going to find out in the next few weeks.

Possibly the start of the end of traditional means of generating electricity
A recent item by David Roberts on the Grist website/Blog caught my eye,
Solar is getting cheap fast—pay attention, Very Serious People
That was the headline to the opening, thus,
I hope everyone has read Kees Van Der Leun’s post about the rapidly falling cost of solar PV. I want to draw out one quick point that Kees leaves implicit.
He argues that PV will be the cheapest source of electricity for most of the world some time around 2018, and for the rest of the world soon after. That could be off by a few years in either direction. It depends on whether the cost curve for silicon solar cells continues as it has the past and, as Alan says in his comment, whether the cost curve for “balance of system” costs (steel, glass, installation, etc.) declines as well. Let’s say it could be off by five years either way. Let’s just assume it’s 2023 before solar PV crosses grid parity and becomes cheaper than coal.
The Kees Van Der Leun post, referred to, points out that,
For a long time, the holy grail of solar photovoltaics (PV) has been “grid parity,” the point at which it would be as cheap to generate one’s own solar electricity as it is to buy electricity from the grid. And that is indeed an important market milestone, being achieved now in many places around the world. But recently it has become clear that PV is set to go beyond grid parity and become the cheapest way to generate electricity.

Whenever I say this I encounter incredulity, even vehement opposition, from friends and foes of renewable energy alike. Apparently, knowledge of the rapid developments of the last few years has not been widely disseminated. But it’s happening, right under our noses! It is essential to understand this so that we can leverage it to rapidly switch to a global energy system fully based on renewable energy.
Working on solar PV energy at Ecofys since 1986, I have seen steady progression: efficiency goes up, cost goes down. But it was only on a 2004 visit to Q-Cells‘ solar cell factory in Thalheim, Germany, that it dawned on me that PV could become very cheap indeed. They gave me a stack of 100 silicon solar cells, each capable of producing 3.8 watts of power in full sunshine. I still have it in the office; it’s only an inch high!
That’s when I realized how little silicon was needed to supply the annual electricity consumption of an average European family (4,000 kWh). Under European solar radiation, it would take 1,400 cells, totaling less than 30 pounds of silicon.
Of course, you need to cover the cells with some glass and add a frame, a support structure, some cables, and an inverter. But the fact that 30 pounds of silicon, an amount that costs $700 to produce, is enough to generate a lifetime of household electricity baffled me. Over 25 years, the family would pay at least $25,000 for the same 100,000 kilowatt-hours (kWh) of electricity from fossil fuels — and its generation cost alone would total over $6,000!
He argues that PV will be the cheapest source of electricity for most of the world some time around 2018, and for the rest of the world soon after. That could be off by a few years in either direction. It depends on whether the cost curve for silicon solar cells continues as it has the past and, as Alan says in his comment, whether the cost curve for “balance of system” costs (steel, glass, installation, etc.) declines as well. Let’s say it could be off by five years either way. Let’s just assume it’s 2023 before solar PV crosses grid parity and becomes cheaper than coal.
Here’s the thing: 2023 isn’t that far off. It feels distant to us in a lot of ways. My kids will be out of college. Fifty versions of the iPhone will have come and gone. We might finally have the jetpacks we were promised.
But in terms of energy infrastructure, 12 years is nothing. It can take half that long or longer to permit and build big coal and nuclear plants, and they are meant to last a long-ass time. The Perry K Steam Plant, which serves downtown Indianapolis, was built in 1938. They didn’t have color TV then. Thirty-six coal plants in the U.S. were built before 1950. If a coal plant built today lasts that long, it will still be belching all over the atmosphere in 2072. My kids will be in their 60s.
This is also true of nuclear plants (the oldest is 42 years) and to a lesser extent natural-gas plants. It’s even true of transmission lines. These are large, long-term investments.
So if solar PV is going to be cheaper than coal in the next decade or so, that seems like the kind of thing utilities, regulators, investors, and political leaders would want to, I don’t know, talk over. Grapple with. Mull. It certainly seems relevant to the investment thesis for large, centralized power infrastructure. Yet it’s all but invisible in the elite U.S. energy conversation, outside of a few voices like FERC Chair Jon Wellinghoff. Very Serious People still see solar PV as an affectation, a kind of charity project.
Hope you are still with me, because this is really an incredibly positive message. By the time children born today are becoming teenagers, the means of harnessing the sun to deliver clean energy cheaper than carbon-based and nuclear generation will be a reality. In a little over a decade from now!
It is so easy to see doom and gloom wherever we look. For good reasons; these are very difficult times as societies pull back from the greed and materialism of recent times to a better, sustainable relationship with our planet, the only one we have. But technology and innovation are quietly creating the opportunities for a new future for humanity.
Let me finish with an email received recently from good friend, John H., up here in Payson, Arizona.
Greetings from a Mountain Top,
It has been another bright and peaceful day of Indian summer in the Ponderosa pine forests of the Arizona Rocky Mountains. Our annual state-wide church convention last weekend was a metaphorical breath of fresh air. It was an opportunity to realize where we’ve been and consider how far we have to go.
From the early evening vantage point of an upper porch with a vista of forest, mountains and sky, it appears that we’re facing spiritual, environmental, human and economic bankruptcy caused by top down idolatry, arrogance and ignorance.
It’s deeply disturbing to watch our human heritage destroyed by a corporate-government-military-industrial-intelligence complex with a clear plan to control the world through oppression. This systemic machine continues to increase the drain on the earth’s severely depleted resources.
Our present energy sources can no longer sustain exponential human population growth. The industrial use of fossil fuels is destroying the earth which sustains us. It’s time for us to wake up and read the book of life. It’s time to lighten the human footprint upon the earth while we still have a choice. Nature doesn’t care about human ambition.
Regular readers of Learning from Dogs know that my pattern is to write a single article each day with a focus on something light and airy over the week-end. But I’m making an exception this Sunday, for two reasons. The first was that I spent a couple of hours yesterday catching up on this week’s The Economist and especially liked the tribute to Steve Jobs; a small extract is below with a link to the full article. The second reason was that friend, Neil K. in South Devon, sent me a lovely graphical tribute that I wanted so much to share with you.
So, first to The Economist article,
Steve Jobs
The magician
The revolution that Steve Jobs led is only just beginning
Oct 8th 2011 | from the print edition
Steve Jobs
WHEN it came to putting on a show, nobody else in the computer industry, or any other industry for that matter, could match Steve Jobs. His product launches, at which he would stand alone on a black stage and conjure up an “incredible” new electronic gadget in front of an awed crowd, were the performances of a master showman. All computers do is fetch and shuffle numbers, he once explained, but do it fast enough and “the results appear to be magic”. Mr Jobs, who died this week aged 56, spent his life packaging that magic into elegantly designed, easy-to-use products.
Read the full article on The Economist website. The article finishes, thus,
Mr Jobs was said by an engineer in the early years of Apple to emit a “reality distortion field”, such were his powers of persuasion. But in the end he conjured up a reality of his own, channelling the magic of computing into products that reshaped entire industries. The man who said in his youth that he wanted to “put a ding in the universe” did just that.
A fascinating point of view of the relationship between humans and animals.
Jean and I were at our regular gardening college class yesterday. It was all about the growing of vegetables. OK, I can hear you thinking, what on earth does that have to do with today’s topic? Simply because the tutor, Cayci V., mused at the start of her lesson how gardeners were great animal lovers and then proceeded to list all the animals she and her husband kept at their home in Globe, about an hour from Payson, Arizona. Cayci admitted to having 5 dogs, 15 cats, 2 emus, 2 llamas, numerous chickens. She also had 2 bison that recently died having been poisoned by Oleander cuttings. Anyway, to the article.
A recent article on the BBC News Magazine was about the need for humans to have contact with animals. It was presented by John Gray who is a political philosopher and author of the book False Dawn: The Delusions of Global Capitalism which argues that free market globalization is unstable and is in the process of collapsing! H’mmm. John is also the author of the book Straw Dogs: Thoughts on Humans and Other Animals, a book that was described by the British Observer newspaper thus,
There is unlikely to be a more provocative or more compelling book published this year than Straw Dogs. A long-time scourge of the delusions of global capitalism, John Gray is one of the most consistently interesting and unpredictable thinkers in Britain. He is unpredictable because, unlike most political commentators, he never ceases to question the underlying assumptions of his own beliefs and prejudices.
Anyway, I’m at risk of digressing, as many of you will regularly notice! The article by John Gray on the BBC News website was published over a couple of weeks ago and, therefore, I feel it not too great a copyright sin to reproduce it in full on Learning from Dogs. It’s a fascinating article.
Why does the human animal need contact with something other than itself, asks John Gray.
Many years ago an eminent philosopher told me he’d persuaded his cat to become a vegan. To begin with I thought he was joking. Knowing a bit about cats, I couldn’t take seriously the idea that they’d give up their predatory ways.
“You must have provided the cat with some pretty powerful arguments,” I said jokingly. “It wasn’t as difficult as you may think,” he replied rather sternly.
He never explained exactly how the transformation was achieved. Was his cat presented with other cats that had converted to veganism – feline role models, so to speak? Had he prepared special delicacies for his cat – snacks that looked like mice but were made of soya, perhaps?
Beginning to suspect that the philosopher might after all be serious, I asked if the cat went out. He told me it did. That answered a part of my puzzlement. Evidently the cat was supplementing its vegan diet by hunting, natural behaviour for cats after all.
I was still a little perplexed though. Cats tend to bring their hunting trophies back home and I wondered how the philosopher had missed seeing them. Had the cat hidden them out of sight? Or were the cat’s trophies prominently displayed but disregarded by the philosopher, marks of atavistic feline behaviour that would eventually disappear as the cat progressed towards a new kind of meat-free life?
The conversation tapered off and I never did get to the bottom of the mystery. The dialogue did set me thinking. Evidently the philosopher thought of the cat as a less evolved version of himself that, with a lot of help, could eventually share his values. But the idea that animals are inferior versions of humans is fundamentally misguided.
Each of the millions of species that evolution has thrown up is different and particular, and the animals with which we share the planet aren’t stages on the way to something else – ourselves. There’s no evolutionary hierarchy with humans perched at the top. The value of animals – or as I’d prefer to say other animals – comes from being what they are. And it’s the fact that they are so different from humans that makes contact with them so valuable to us.
Human qualities
Some philosophers – not many it must be admitted – have in the past understood this. The 16th Century French essayist, Michel de Montaigne, loved cats because he knew he would never be able to enter their minds. “When I play with my cat,” he asked, “how do I know she is not amusing herself with me rather than I with her?”
Montaigne didn’t want his animal companions to be mirrors of himself, he wanted them to be a window from which he could look out from himself and from the human world.
Never more than partly domesticated, cats are never fundamentally humanised. Montaigne found them lovable for precisely this reason, it wasn’t that he was suggesting we should emulate cats. Wiser than the philosopher who believed he’d converted his cat to veganism, he understood that the good life means different things for animals with different natures. What he questioned was the idea that one kind of life, the kind humans alone can live, is always best.
It’s true that cats don’t have some of the capacities we associate with morality. They seem to lack empathy, the capacity of identifying with the emotions of others. This may explain what has often been described as cruelty in their behaviour, toying with captured mice for example. Attributing cruelty to cats seems a clear case of anthropomorphism – the error of projecting distinctively human qualities onto other species.
Cats are not known to display compassion, but neither do they inflict pain and death on each other in order to gratify some impulse or ideal of their own. There are no feline inquisitors or suicide bombers. Pedants will say that this is because cats lack the intellectual equipment that is required to formulate an idea of truth or justice. I prefer to think that they simply decline to be enrolled in fanaticism, another peculiarly human trait.
Dogs seem to be capable of showing human-like emotions of shame, but though they are more domesticated they still remain different from us. And I think it’s their differences from us, as much as their similarities, that makes them such good companions.
Whatever you feel about cats and dogs, it seems clear that the human animal needs contact with something other than itself. For religious people this need may be satisfied by God, even if the God with whom they commune seems too often all-too-human. For many landscape gives a sense of release from the human world, even if the land has been groomed and combed by humans for generations, as it has in England.
The contemplation of field, wood and water intermingling with wind and sky still has the power to liberate the spirit from an unhealthy obsession with human affairs. Poets such as Edward Thomas and Ted Hughes have turned to the natural world in an attempt to escape a purely human view of things. Since they remained human and used human language in the attempt, it’s obvious that they couldn’t altogether succeed. It’s also obvious that searching for a way of looking at the world that’s not simply human expresses a powerful human impulse.
The most intense example of this search I know is that recorded by John Baker in his book The Peregrine. First published in 1967 and recently reissued, the book is seemingly a piece of nature writing which slowly reveals itself as the testament of someone struggling to shed the point of view of a human observer.
Renewed humanity
Baker records his pursuit of two pairs of peregrines, which had arrived to hunt in the part of East Anglia where he lived. Alone he followed the birds for over 10 years. Concentrating the decade-long quest into a single year in order to recount it in the book, he writes of the peregrine: “Wherever he goes, this winter, I will follow him. I will share the fear, and the exaltation, and the boredom of the hunting life.”
He tells us that he came late to the love of birds. “For years I saw them only as a tremor on the edge of vision. They know suffering and joy in simple states not possible for us. Their lives quicken and warm to a pulse our hearts can never reach. They race to oblivion.”
In time the human observer seemed to be transmuted into the inhuman hawk. “In a lair of shadow,” Baker writes, “the peregrine was crouching, watching me… We live, in these days in the open, the same ecstatic fearful life. We shun men.”
Note how Baker switches suddenly from describing the hawk watching him to describing how “we” flee from humans. Baker found a sensation of freedom in the feeling that he and the hawk were fused into one. Sharing in the “exaltation and serenity” of the birds’ life he could imagine that he’d shed his human identity, at least for a time, and could view the world through hawks’ eyes.
Of course he didn’t take this to be literal truth. He knew he couldn’t in the end be anything other than human. Yet he still found the pursuit of the peregrine deeply rewarding, for it opened up a temporary exit from the introspective human world.
John Baker’s devotion to the peregrine hadn’t enabled him to see things as birds see them. What it had done was to enable him to see the world through his own eyes, but in a different way. His descriptions of the landscape of East Anglia are exact and faithful to fact. But they reveal that long-familiar countryside in a light in which it looks as strange and exotically beautiful as anything in Africa or the Himalayas. The pursuit of a bird had revitalised his human perceptions.
What birds and animals offer us is not confirmation of our sense of having an exalted place in some sort of cosmic hierarchy, it’s admission into a larger scheme of things, where our minds are no longer turned in on themselves. Unless it has contact with something other than itself, the human animal soon becomes stale and mad. By giving us the freedom to see the world afresh, birds and animals renew our humanity.
A fascinating, beautiful and incredibly thought-provoking essay.
With great thanks to Dan G. for sending me the link.
Science educator James Drake built this amazing timelapse video from the perspective of the International Space Station as it flew over North and South America. He created this video by downloading a series of 600 photographs that were available online at theGateway to Astronomy Photograph of Earth, and then stitching them together into a complete video. You can see more of James work at his blog: infinity imagined.
Those who read yesterday’s part one will undoubtedly have seen the added comment from long-time friend of Learning from Dogs, Patrice Ayme. Yesterday, I promised to conclude Dan’s sceptical approach to climate warming with three articles that he had sent me. Here they are,
Global Warming
“Global warming” refers to the global-average temperature increase that has been observed over the last one hundred years or more. But to many politicians and the public, the term carries the implication that mankind is responsible for that warming. This website describes evidence from my group’s government-funded research that suggests global warming is mostly natural, and that the climate system is quite insensitive to humanity’s greenhouse gas emissions and aerosol pollution.
Believe it or not, very little research has ever been funded to search for natural mechanisms of warming…it has simply been assumed that global warming is manmade. This assumption is rather easy for scientists since we do not have enough accurate global data for a long enough period of time to see whether there are natural warming mechanisms at work.
The United Nation’s Intergovernmental Panel on Climate Change (IPCC) claims that the only way they can get their computerized climate models to produce the observed warming is with anthropogenic (human-caused) pollution. But they’re not going to find something if they don’t search for it. More than one scientist has asked me, “What else COULD it be?” Well, the answer to that takes a little digging… and as I show, one doesn’t have to dig very far.
But first let’s examine the basics of why so many scientists think global warming is manmade. Earth’s atmosphere contains natural greenhouse gases (mostly water vapor, carbon dioxide, and methane) which act to keep the lower layers of the atmosphere warmer than they otherwise would be without those gases. Greenhouse gases trap infrared radiation — the radiant heat energy that the Earth naturally emits to outer space in response to solar heating. Mankind’s burning of fossil fuels (mostly coal, petroleum, and natural gas) releases carbon dioxide into the atmosphere and this is believed to be enhancing the Earth’s natural greenhouse effect. As of 2008, the concentration of carbon dioxide in the atmosphere was about 40% to 45% higher than it was before the start of the industrial revolution in the 1800’s.
It is interesting to note that, even though carbon dioxide is necessary for life on Earth to exist, there is precious little of it in Earth’s atmosphere. As of 2008, only 39 out of every 100,000 molecules of air were CO2, and it will take mankind’s CO2 emissions 5 more years to increase that number by 1, to 40.
Earth's atmosphere
The “Holy Grail”: Climate Sensitivity Figuring out how much past warming is due to mankind, and how much more we can expect in the future, depends upon something called “climate sensitivity”. This is the temperature response of the Earth to a given amount of ‘radiative forcing’, of which there are two kinds: a change in either the amount of sunlight absorbed by the Earth, or in the infrared energy the Earth emits to outer space.
The ‘consensus’ of opinion is that the Earth’s climate sensitivity is quite high, and so warming of about 0.25 deg. C to 0.5 deg. C (about 0.5 deg. F to 0.9 deg. F) every 10 years can be expected for as long as mankind continues to use fossil fuels as our primary source of energy. NASA’s James Hansen claims that climate sensitivity is very high, and that we have already put too much extra CO2 in the atmosphere. Presumably this is why he and Al Gore are campaigning for a moratorium on the construction of any more coal-fired power plants in the U.S.
You would think that we’d know the Earth’s ‘climate sensitivity’ by now, but it has been surprisingly difficult to determine. How atmospheric processes like clouds and precipitation systems respond to warming is critical, as they are either amplifying the warming, or reducing it. This website currently concentrates on the response of clouds to warming, an issue which I am now convinced the scientific community has totally misinterpreted when they have measured natural, year-to-year fluctuations in the climate system. As a result of that confusion, they have the mistaken belief that climate sensitivity is high, when in fact the satellite evidence suggests climate sensitivity is low.
The case for natural climate change I also present an analysis of the Pacific Decadal Oscillation which shows that most climate change might well be the result of….the climate system itself! Because small, chaotic fluctuations in atmospheric and oceanic circulation systems can cause small changes in global average cloudiness, this is all that is necessary to cause climate change. You don’t need the sun, or any other ‘external’ influence (although these are also possible…but for now I’ll let others work on that). It is simply what the climate system does. This is actually quite easy for meteorologists to believe, since we understand how complex weather processes are. Your local TV meteorologist is probably a closet ’skeptic’ regarding mankind’s influence on climate.
Climate change — it happens, with or without our help.
And the next one,
Earth may be headed into a mini Ice Age within a decade
Physicists say sunspot cycle is ‘going into hibernation’
What may be the science story of the century is breaking this evening, as heavyweight US solar physicists announce that the Sun appears to be headed into a lengthy spell of low activity, which could mean that the Earth – far from facing a global warming problem– is actually headed into a mini Ice Age.
Ice skating on the Thames by 2025?
The announcement made on 14 June (18:00 UK time) comes from scientists at the US National Solar Observatory (NSO) and US Air Force Research Laboratory. Three different analyses of the Sun’s recent behaviour all indicate that a period of unusually low solar activity may be about to begin.
The Sun normally follows an 11-year cycle of activity. The current cycle, Cycle 24, is now supposed to be ramping up towards maximum strength. Increased numbers of sunspots and other indications ought to be happening: but in fact results so far are most disappointing. Scientists at the NSO now suspect, based on data showing decades-long trends leading to this point, that Cycle 25 may not happen at all.
This could have major implications for the Earth’s climate. According to a statement issued by the NSO, announcing the research:
An immediate question is whether this slowdown presages a second Maunder Minimum, a 70-year period with virtually no sunspots [which occurred] during 1645-1715.
As NASA notes [1]:
Early records of sunspots indicate that the Sun went through a period of inactivity in the late 17th century. Very few sunspots were seen on the Sun from about 1645 to 1715. Although the observations were not as extensive as in later years, the Sun was in fact well observed during this time and this lack of sunspots is well documented. This period of solar inactivity also corresponds to a climatic period called the “Little Ice Age” when rivers that are normally ice-free froze and snow fields remained year-round at lower altitudes. There is evidence that the Sun has had similar periods of inactivity in the more distant past.
During the Maunder Minimum and for periods either side of it, many European rivers which are ice-free today – including the Thames – routinely froze over, allowing ice skating and even for armies to march across them in some cases.
“This is highly unusual and unexpected,” says Dr Frank Hill of the NSO. “But the fact that three completely different views of the Sun point in the same direction is a powerful indicator that the sunspot cycle may be going into hibernation.”
Hill’s own research focuses on surface pulsations of the Sun and their relationship with sunspots, and his team has already used their methods to successfully predict the late onset of Cycle 24.
“We expected to see the start of the zonal flow for Cycle 25 by now,” Hill explained, “but we see no sign of it. This indicates that the start of Cycle 25 may be delayed to 2021 or 2022, or may not happen at all.”
Hill’s results match those from physicists Matt Penn and William Livingston, who have gone over 13 years of sunspot data from the McMath-Pierce Telescope at Kitt Peak in Arizona. They have seen the strength of the magnetic fields which create sunspots declining steadily. According to the NSO:
Penn and Livingston observed that the average field strength declined about 50 gauss per year during Cycle 23 and now in Cycle 24. They also observed that spot temperatures have risen exactly as expected for such changes in the magnetic field. If the trend continues, the field strength will drop below the 1,500 gauss threshold and spots will largely disappear as the magnetic field is no longer strong enough to overcome convective forces on the solar surface.
In parallel with this comes research from the US Air Force’s studies of the solar corona. Richard Altrock, in charge of this, has found a 40-year decline in the “rush to the poles” – the poleward surge of magnetic activity in the corona.
“Those wonderful, delicate coronal features are actually powerful, robust magnetic structures rooted in the interior of the Sun,” Altrock says. “Changes we see in the corona reflect changes deep inside the Sun …
“Cycle 24 started out late and slow and may not be strong enough to create a rush to the poles, indicating we’ll see a very weak solar maximum in 2013, if at all. If the rush to the poles fails to complete, this creates a tremendous dilemma for the theorists … No one knows what the Sun will do in that case.”
According to the collective wisdom of the NSO, another Maunder Minimum may very well be on the cards.
“If we are right,” summarises Hill, “this could be the last solar maximum we’ll see for a few decades. That would affect everything from space exploration to Earth’s climate.”
The effects on space exploration would be benign, as fewer or no solar storms would make space a much less hostile environment for human beings. At the moment, anyone venturing beyond the Earth’s protective magnetic field (the only people to have done so were the Apollo moon astronauts of the 1960s and ’70s) runs a severe risk of dangerous or fatal radiation exposure during a solar storm.
Manned missions beyond low Earth orbit, a stated aspiration of the USA and other nations, might become significantly safer and cheaper to mount (cheaper as there would be no requirement for possibly very heavy shielding to protect astronauts, so reducing launch costs).
The big consequences of a major solar calm spell, however, would be climatic. The next few generations of humanity might not find themselves trying to cope with global warming but rather with a significant cooling. This could overturn decades of received wisdom on such things as CO2 emissions, and lead to radical shifts in government policy worldwide.

On the Misdiagnosis of Surface Temperature Feedbacks from Variations in Earth’s Radiant Energy Balance

Abstract: The sensitivity of the climate system to an imposed radiative imbalance remains the largest source of uncertainty in projections of future anthropogenic climate change. Here we present further evidence that this uncertainty from an observational perspective is largely due to the masking of the radiative feedback signal by internal radiative forcing, probably due to natural cloud variations. That these internal radiative forcings exist and likely corrupt feedback diagnosis is demonstrated with lag regression analysis of satellite and coupled climate model data, interpreted with a simple forcing-feedback model. While the satellite-based metrics for the period 2000–2010 depart substantially in the direction of lower climate sensitivity from those similarly computed from coupled climate models, we find that, with traditional methods, it is not possible to accurately quantify this discrepancy in terms of the feedbacks which determine climate sensitivity. It is concluded that atmospheric feedback diagnosis of the climate system remains an unsolved problem, due primarily to the inability to distinguish between radiative forcing and radiative feedback in satellite radiative budget observations.
So back to me!
As you can see there is every opportunity to be confused. Not embracing contrary views to the ones that you believe, however, is not the way to determine the truth.
So let me close with a couple of my own contrary views.
We have a tiny window of opportunity to save something of the magnificence of the Earth so let’s all grab it, writes Bill McKibben, founder of 350.org
Asked to name the biggest thing that’s happened over Resurgence’s 45-year career, I think I’d have to say the melt of the Arctic. When this magazine began publishing, there was 40% more summer sea ice in the Arctic. Viewed from space, in those first pictures from the Apollo spacecraft, the planet looked very different than it does now. In recent summers both the north-west and the north-east passages have opened, allowing sailors to circumnavigate the Arctic through waters that no one thought, even a decade ago, humans would ever navigate.
Or maybe I would pick the rapid acidification of the planet’s seas – they’re 30% more acid than they were in 1966. Which means that the small creatures at the base of the marine food chain are having more trouble forming their shells, and that coral reefs – already stressed by warming waters – have a new trauma to deal with.
Another possibility: the Earth’s atmosphere is about 4% moister than it was 45 years ago, simply because warm air holds more water vapour than cold. This loads the dice for deluge, downpour, flood – it’s not surprising that we’re seeing record rainfall and unprecedented floods. Nor, since that water has to come from somewhere, should increasing drought and desertification come as much of a shock.
Here’s what I’m trying to say: when Resurgence began its run, we were still in the Holocene. Humans had altered much of the planet’s natural environment. We had dirty rivers and dirty air, spreading toxins and endangered species. But the basic operating system of the planet was running pretty much the same as it had for the 10,000 years of human civilisation.
Sometime in the intervening decades we moved out of that comfortable and remarkably stable world, and began the transition to What Comes Next?
Any date would be arbitrary, but if you wanted to pick one, you could say 1988. That was the year NASA scientist Jim Hansen warned the US Congress that global warming was indeed real – and it was the year that we passed the benchmark of 350 parts per million (ppm) of CO2 in the atmosphere. At the time we didn’t know it was a benchmark – it was 20 years later that scientists, again led by Hansen, declared that 350ppm was the absolute upper limit if we wanted a planet “similar to the one on which civilisation developed and to which life is adapted”. If we wanted, in other words, that older world we were born onto.
I could list at some length the various woes this new world is already causing: we see rising sea levels displacing farmers across the deltas of Bangladesh, and Aedes aegypti expanding its boundary and spreading dengue fever like wildfire. Speaking of wildfire, we see record amounts, in part because of more heat and drought, and in part because insects (once kept in check by cold weather) are now spreading.
We see millions still homeless from last year’s flood in Pakistan, and billions struggling to pay for food because a string of crop failures that began with last summer’s Russian drought have increased grain prices by 70–80%.
And I could list at even greater length the woes we expect as the century grinds on. After all, we’ve only raised the temperature about a degree so far, and the climatologists tell us to expect four or five unless we stop burning coal and oil and gas much faster than any government currently plans. Temperatures like that will guarantee the melt of Greenland; according to the agronomists they will cut grain harvests by a third or more; they’ll make current shortages of water seem barely worth mentioning.
But for the moment don’t think about consequences, current or future. Just think about the enormity of what we’ve managed to do: we’ve altered the most basic operations of the one planet we’ve got.
The air is profoundly different, the heat balance with our sun profoundly altered. It’s by far the biggest thing humans have ever done or ever contemplated doing, and were some alien watching from a great distance she’d be scratching her head-like appendage. It’s our head-like appendage that’s responsible, of course. That big brain turned out to be incredibly clever, and its cleverest trick was to figure out that buried carbon could make life easy. Everything that we know around us – the whole modern world – derives from that discovery. Much of it is good. But now we’re threatening to take down the good, and much else with it.
So here’s the question for the next 45 years of Resurgence: can the big brain bail us out?
It’s already provided us with the warnings we need, warnings that would not have been available at any other moment in human history. The scientific method, one of the greatest achievements of our civilisation, has produced a robust consensus on this difficult problem in chemistry and physics: since the mid-1990s the Intergovernmental Panel on Climate Change (IPCC) has said in unmistakably plain language that there is no doubt: we have to cut carbon, and quickly.
But so far that warning has had little or no effect: our national governments, with a few noble exceptions, have paid scant attention; our attempts at global governance have been pathetic failures. The chief reason, I think, is the remarkable power of the fossil-fuel industry to stifle change; for 200 years it has grown bigger and richer and more than able to deal with the threat that science now poses to its reign. It literally makes us stupid: earlier this winter the US House of Representatives, by a 60-vote margin, defeated a resolution that merely stated that global warming was real. Exxon has promoted its own version of physics and chemistry, and they’ve managed to fool a good many too.
The real question, then, is going to be: is there a big enough heart connected to that big brain? Will we be able to heed not only the warnings of science but those of our conscience? Will we, gazing out at the growing array of ‘natural disasters’, figure out that we’ve got to make change? Change in our personal lives, yes, but even more change in our political arrangements, since that’s the only chance that actual physics and chemistry really give us for meeting the deadlines they’ve set.
I think the answer is yes – a tentative and uncertain yes, but one based on just enough real-world data to give me hope.
Three years ago we founded 350.org, the first big global grassroots climate campaign. Rooted in science but expressed in imagination, it has grown to pretty mammoth size. Our first two big global days of action, in the waning months of 2009 and 2010, were what CNN called “the most widespread days of political action in the planet’s history”, with nearly 15,000 demonstrations in every country on Earth but North Korea.
And the good news is we didn’t really ‘organise’ it – our tiny staff worked feverishly, but ultimately it was like a potluck supper. People in every corner of the Earth heard the call and did the work, figuring out what would work in their place. (An underwater demonstration on the dying coral reefs of the Maldives; a giant image of King Canute, composed of thousands of volunteers, trying to hold the sea back on the Brighton seashore!)
It’s not enough yet to beat the fossil-fuel industry – our bodies don’t yet add up to their money. But we’re growing constantly (the next big chance to join us: 24 September 2011, a day we’re calling Moving Planet). And – sad, but true – the natural world is going to continue to give us openings to make the case more strongly. Sooner or later our leaders will listen – and we’re committed to making it sooner.
We’re not going to stop global warming: it’s already warmed and it will warm some more. Those Apollo images of our planet are forever sepia-toned. But we’ve got a tiny window left to save something of the Earth we were born onto – its beauty, its bounty, its safety.
That’s our task, and the next 45 years will tell the tale.
Bill McKibben wrote the first book for a general audience on climate change, The End of Nature, in 1989. He is a scholar in residence at Middlebury College in Vermont.
That value is 36% lower than the average minimum for 1979-2000.
NSIDC said the figure was preliminary, and that “changing winds could still push the ice extent lower” before final numbers are published in early October.
The preliminary value is 160,000 sq km – or 4% – above the record minimum seen in 2007.
The minimum level of cover is far below the average of 1979-2000
“While the record low year of 2007 was marked by a combination of weather conditions that favoured ice loss – including clearer skies, favourable wind patterns and warm temperatures – this year has shown more typical weather patterns but continued warmth over the Arctic,” they wrote.
“This supports the idea that the Arctic sea ice cover is continuing to thin.”
NSIDC director Mark Serreze said: “Every summer that we see a very low ice extent in September sets us up for a similar situation the following year.
“The Arctic sea ice cover is so thin now compared to 30 years ago that it just can’t take a hit any more. This overall pattern of thinning ice in the Arctic in recent decades is really starting to catch up with us.”
In fact, an analysis released last week by researchers at the University of Bremen in Germany, who use a different satellite to assess ice cover, indicated that 2011’s minimum was the lowest on record.
However, there is some controversy surrounding the result; the Bremen team’s higher-resolution data can detect small patches of water where the NSIDC team would not, but the Bremen record goes back only to 2003.
These analyses are for the extent, or area, of Arctic ice, but recent estimates released by the University of Washington’s Polar Science Center give an indication of the total amount of sea ice.
Their data indicate that the ice volume is at an all-time low for the second year in a row.
Analyses of Arctic ice in recent years consistently indicate a change in the nature of the ice itself – from one solid mass that melts and freezes at its edges towards more dispersed, piecemeal ice cover, and from robust “multi-year” ice toward seasonal floes that melt more easily.
The NSIDC data show ice cover extents consistently below earlier averages
You may want to refer to the worrying images of the Petermann Glacier that I published on the 14th September.

I hope this article, split over two days, has been useful. Hopefully, they underline the need to work it out for yourself and remain open-minded at all times.
Musings about the importance of challenging accepted wisdoms
Life is full of traps. In that sense our lives are little different to our ancient days of cavemen. But the traps are very different. They have changed from pits embedded with sharp sticks, covered with vegetation, to an avalanche of information, news and media output from which determining truth is challenging. The modern equivalent of the ancient pit trap.
My sense is that one way we embrace what we perceive as truthful is through pattern matching, a powerful aspect of the human brain. By pattern matching, I mean the tendency to place greater emphasis on information that matches our view of the world, that accords with our core beliefs, than that which doesn’t.
Thus if one is a liberal with leanings towards social engineering as a means of improving society then news and information that supports that philosophy will be accepted as validation of that view. Then again, if one is strong on the need for the individual to be independent and responsible for their own lives then the validation of that philosophy will be supported by a completely different stream of information.
A prologue to what follows.
Regular readers of Learning from Dogs will be clear that my view is that mankind is responsible for a range of issues that, if not resolved, will threaten the very ecology of Planet Earth that allows mankind to survive. My dear Californian friend of over 40 years, Dan, thinks otherwise. Let me add, Dan is not a mental slouch.
I wanted to share some articles that Dan recently sent me, not to prove who is right or wrong, but to underline the critical importance of never ceasing to question the truth of everything that is fundamental to our knowledge of the world, in the broadest sense, upon which we live.
New NASA Data Blow Gaping Hole In Global Warming Alarmism
NASA satellite data from the years 2000 through 2011 show the Earth’s atmosphere is allowing far more heat to be released into space than alarmist computer models have predicted, reports a new study in the peer-reviewed science journal Remote Sensing. The study indicates far less future global warming will occur than United Nations computer models have predicted, and supports prior studies indicating increases in atmospheric carbon dioxidetrap far less heat than alarmists have claimed.
Study co-author Dr. Roy Spencer, a principal research scientist at the University of Alabama in Huntsville and U.S. Science Team Leader for the Advanced Microwave Scanning Radiometer flying on NASA’s Aqua satellite, reports that real-world data from NASA’s Terra satellite contradict multiple assumptions fed into alarmist computer models.
“The satellite observations suggest there is much more energy lost to space during and after warming than the climate models show,” Spencer said in a July 26 University of Alabama press release. “There is a huge discrepancy between the data and the forecasts that is especially big over the oceans.”
In addition to finding that far less heat is being trapped than alarmist computer models have predicted, the NASA satellite data show the atmosphere begins shedding heat into space long before United Nations computer models predicted.
The new findings are extremely important and should dramatically alter the global warming debate.
This is not the full article, which may be read here.
I was interested in what had been published by Yahoo News and sought to verify it directly on NASA’s web site. I was unable to do so, and replied with links to two findings by NASA that man, indeed, was affecting global climate. One of those NASA links was here,
A new NASA-led study shows that human-caused climate change has impacted a wide range of Earth’s natural systems, from permafrost thawing to plants blooming earlier across Europe to lakes declining in productivity in Africa.
Cynthia Rosenzweig of NASA’s Goddard Institute for Space Science in New York and scientists at 10 other institutions have linked physical and biological impacts since 1970 with rises in temperatures during that period. The study, published May 15 in the journal Nature, concludes that human-caused warming is resulting in a broad range of impacts across the globe.
adding my own view that “There isn’t a serious scientist in the world who has published a peer-reviewed paper that disagrees with the core notion that man has affected the planet. ”
Dan responded thus,
Paul – This will be a good one.
The point I always try to make is that good science is always subject to change as new evidence is discovered. I believe that science is by nature, controversial; plus ça change and all that….
To state as a “Hard-Core Ideological Truth” that Anthropogenic Global Warming (now known as more PC “Climate Change”) is a fact is self-serving. To deny the disputative work of many highly regarded scientists and climatologists who challenge this construct, can only result in a politically charged and alarmist position serving, in the end, special-interests.
Being skeptical is a healthy process. This process should be followed in the “Climate Change” debate. Especially in the face of today’s political reality and the funding that special interest groups need to survive. Regarding the proclamations of “Man-Induced Global Warming/Climate Change Proponents” that Man is and will be single-handedly responsible for the global flooding of most of the world’s coastal cities, is arrogant, absurd and unprovable.
Moreover, to ask world governments to take billions and billions of dollars out of their economies to fund nutty programs like “Cap and Trade” in order to ostensibly “contradict” something that has been happening on its own for millions of years, is pretty much over the top.
For the last 2 million years, Earth cycles in and out of ice ages. It happens whether the planet supports 20 million people or 20 million dinosaurs. Glaciers grow and recede. Polar ice increases and decreases. The planet shifts its axis a few degrees and it gets cold. It shifts back, it gets hotter. Ocean currents change based on God’s unpredictable timetable causing local droughts and floods. A few volcanoes erupt and we get instant cloud cover drifting over the planet changing climatology drastically. The Sun, its relative position to Earth and its sunspot cycles adds a little flavor. How about putting the Earth’s wobble in the mix? Or, for that matter, without the Moon we would have no seasons?
Greenhouse gases are mostly water vapor. After that, CO2 and methane. All together, very small components of the Earth’s atmosphere. That should tell us something.
If you go to NASA scientist, Dr. Spencer’s website – http://www.drroyspencer.com -, you may find some interesting data from his studies that suggest that man-made caused CO2 entering the atmosphere is not all that important. At the very least, this is a controversial subject that should be treated that way and not as fact. And please, don’t tax me more to pay for unsubstantiated programs to make it snow more in the Arctic. What if it snows too much or get’s too cold and Hudson and the Thames freeze again. Rather be warm than cold.
And by “peel-back-the-onion”, I mean that any ardent, independent researcher should publish both sides of the story as a matter of course. Especially in regards to global warming.
For what it is worth, I personally believe that the “Anthropogenic Global Warming Crisis” is an attempt by “Political Man” to assign full blame to the “Global Industrial Sector” for increased CO2 emissions which, in turn, will rapidly create an atmospheric, hydrospheric and lithospheric catastrophe beyond anything Man has every seen (Love that one!). Once that blame can become an incontrovertible truth and that Man is proven Responsible, then the Industrial Enterprises of the Advanced Nations (they have all the money, or they used to) will pay billions to Create Government Managed Programs to Decrease CO2 Emissions and Prevent this World-Ending Catastrophe from ever taking place. Wow.
Instead, what we should really be focused on is something a little more banal like Jobs, freeing up Global Enterprises from regulations and taxes, adjusting our Social Entitlement Programs to fit revenues and paying back Debt. That’s the Red Meat of this era, in my humble opinion.
Paul, I gotta say, this is fun! See more below…..
Dan then included more background articles that will be the subject of Sceptical Voices, Part Two. Hope you can stay with it.
I must immediately volunteer the fact that the thrust of this article is the result of a programme that we watched last Thursday night. It was a programme originally featured on the UK BBC 4 channel in 2008. Called High Anxieties, The Mathematics of Chaos, it is a fascinating examination into the way that mathematicians have fundamentally adjusted their views, from the certainty of Newtonian principles to the certain uncertainty offered by mathematicians such as Henri Poincare and Alexander Lyapunov. The 60-minute documentary, directed by David Malone, is wonderfully interesting and much more relevant to the uncertainty surrounding all our lives than one might anticipate from any references to mathematicians! It puts the collapse of Lehman Brothers, some 2 years ago, last Thursday, into an interesting perspective.
Here’s the first 9 minutes as offered on YouTube, introduced thus,
David Malone http://golemxiv-credo.blogspot.com author of The Debt Generation, directs and presents this film, It is the first part of a documentary first shown on BBC4 Television in the UK in September 2008. The film was first broadcast 2 days after the collapse of Lehman brothers at the start of the financial crisis. It looks at the discoveries in mathematics during the 20th Century which have challenged the view that the world is an essentially knowable and therefore controllable place. The film focuses on the economy and the environment and suggests that ideas about unpredictability, the butterfly effect and tipping points, stemming from mathematics, are part of what underlie some modern anxieties about the world we live in.
If this first part grabs your attention then finding the other 8 parts is easy on YouTube. Alternatively, the complete set of videos is linked together as one film on Top Documentary Films, click High Anxieties: The Mathematics of Chaos. where it is described as follows,
The documentary looks at the modern advances in mathematics and how they affect our understanding of physics, economics, environmental issues and human psychology.
The film looks at how developments in 20th Century mathematics have affected our view of the world, and particularly how the financial economy and earth’s environment are now seen as inherently unpredictable.
The film looks at the influence the work of Henri Poincare and Alexander Lyapunov had on later developments in mathematics. It includes interviews with David Ruelle, about chaos theory and turbulence, the economist Paul Ormerod about the unpredictability of economic systems, and James Lovelock the founder of Gaia theory about climate change and tipping points in the environment.
As we approach tipping points in both the economy and the climate, the film examines the mathematics we have been reluctant to face up to and asks if, even now, we would rather bury our heads in the sand rather than face harsh truths.
Very, very interesting and rather puts the pictures of the Petermann Glacier shown here into context.
We must never lose sight of the greater power of positive thoughts.
Indeed, who cannot look at a dog’s wagging tail and not feel better about life. There is so much doom and gloom around that we need constantly to remind ourselves that there is a brighter future ahead, there always is.
And to understand how little it takes for a positive difference to sweep through, take a look at this article from Science Daily,
Scientists at Rensselaer Polytechnic Institute have found that when just 10 percent of the population holds an unshakable belief, their belief will always be adopted by the majority of the society.
The implications of this are profound. Be sure that we are living through a transition period, a period necessary to find a better future. Find another nine people who agree with you, and there’s a hundred on their way! Back to the article,
“When the number of committed opinion holders is below 10 percent, there is no visible progress in the spread of ideas. It would literally take the amount of time comparable to the age of the universe for this size group to reach the majority,” said SCNARC Director Boleslaw Szymanski, the Claire and Roland Schmitt Distinguished Professor at Rensselaer. “Once that number grows above 10 percent, the idea spreads like flame.”
