More on the many and varied approaches to this complex subject. Again, a long piece which, dear reader, I hope you will stay with.
As I wrote in response to Per Kurowski’s comment on yesterday’s Part One of this article, ” I am reminded of the saying that in war the first casualty is truth. It ‘feels’a lot like that in this scenario.”
Part Two isn’t attempting to indicate the truth, just the many opinions out there.
First, let me quote an email that Patrice sent to me late last night,
Hi Paul!
I think that the propaganda from the fossil fuel and other feudal plutocracies have confused the issue. The primary problem is not “climate change” (aka planetary heating/broiling).I am not confused, because it’s NOT about climate change. Climate change is a second order effect. It may, or may not happen, short term.
The gist of my essay is that climate change will NOT happen, short term, if the sun cools down spectacularly, as it did TWICE in the last five centuries (~ Little Ice Age).
The way to look at things correctly, thus, is CO2 POISONING. Even if the sun cooled down spectacularly, as I emphasized, the ACIDIFICATION of the oceans would proceed unabated. After killing the oceans, if the sun goes back to normal, the greenhouse would rebound enormously.
Although I did not speak of it in that particular essay, we now know the rate of CO2 in the atmosphere, through shell formation in the ocean, for at least 20 million years (and soon at least 100 million; the method should work for half a billion years!). Thus we know the level of CO2 equivalent is the highest in 20 million years (although some have claimed that transitory fluxes much higher than that have occured, from volcanoes; that would not be a problem, as a high flux does not allow storage in the oceans!)
Feel free to quote from this, I just thought of this formulation now, and it may help clarify matters (and it is clearly the idea of the essay). BTW, let me emphasize that my essay explains why FLOODING, by no means certain on a proxymal massive scale, is, however a clear possibility. London under water seems even a near certainty on the scale of a century (but for enormous works, requiring huge energy!)
Patrice
OK, a useful footnote to yesterday’s piece. But then if one goes back to Patrice’s original article on his Blog on 31st May, 2009 and reads the comments, you find this, (and I’m going to quote entirely from Mr Day’s comments).
Barry Day says
(QUOTE)What does this mean? We should be cooling down, because the sun’s output has been going down as much as an astounding 6% in some frequencies. But, nevertheless, the lower troposphere has been warming up (END QUOTE)
Ever heard of lag?
“New data show that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed approximately constant since 1850, despite emissions of carbon dioxide having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now.”
“This suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected.” From Pysorg.com of November 10th, 2009.
“Apart from the “long-term” trends shown above, which show an ongoing persistent increase, it is perhaps more stark to record that earthquakes across the planet show a marked increase in activity since 1997. There are more major earthquakes occurring now, and this on an ever more frequent basis.”
“A total of 1,085 earthquakes measuring magnitude 6 or greater occurred between 1980 to 1989, averaging 109 per year over the decade. In the 1990s the decadal total increased to 1,492 averaging at 149 major earthquake per year over the period.
Since January 1, 2000 [ see table below for the date and time] a total of 1,438 major earthquakes have so far occurred worldwide raising the annual total over the last 9 years to 160 with more than 12 and a half months to go to the decade’s end.
The increase from 109 to 160 major earthquakes per year in the 1980 to 2008 period translates to a rise of 47 percent in just under three decades.” [This reference is dated December 13th, 2008, before the Japanese earthquake, Ed.]
The Barry Day goes on to highlight these references,
Abstract
The United Nations Intergovernmental Panel on Climate Change (IPCC) released its Fourth Assessment Report (AR4) in 2007. Here we show that the accurate value for climate sensitivity is 0.277 K/(W/m^2), which is 3 times smaller than the generally accepted value of 0.8 K/(W/m^2). Thus the climate change on doubling CO2 from 300 ppm to 600 ppm will be 1.0 degree, not 3 degrees. Because the IPCC data show that doubling CO2 will not double absorption of infrared radiation, the Beer-Lambert law is not being followed, because of diminishing returns after more-than-50% absorption.

Then Barry adds another comment,
We’ve forgotten that this isn’t the first time our seas have warmed. Sea temperatures also shot upward 10º to 18ºF just prior to the last ice age.
As the oceans warmed, evaporation increased. The excess moisture then fell to the ground as giant blizzards, giant storms and floods (Noah’s Deluge type floods), and a new ice age began.
The same thing is happening today.
It’s not global warming, it’s ocean warming, and humans have nothing to do with it. Our seas are being heated, I believe, by underwater volcanism. Here’s why:
We are living in a period of vastly increased volcanism, said Dixy Lee Ray in her 1993 book Environmental Overkill, the greatest in 500 years. Eighty percent of all volcanism (say experts at NOAA) occurs underwater. Therefore, underwater volcanism should also be the greatest in 500 years.
Our seas, heated by underwater volcanism, are leading us directly into the next ice age . . . and we don’t even know it.
That’s what El Niño is all about. Warmer seas send excess moisture into the sky, leading to increased precipitation.
Worldwide flood activity is the worst since before Christopher Columbus. In Poland, it’s the worst in several thousand years. In the U.S., precipitation has increased 20 percent just since 1970. This is no coincidence.
When that precipitation begins falling in the winter, you have the makings of an ice age.
South America’s oldest trees give up the ghost of climate past.
They’ve been dead for over 50,000 years, but South America’s longest-living trees still have a few tales to tell. A new study of the growth rings of partially fossilized trees in southern Chile hints that the global climate before the last ice age was rather like today’s.
Barry mentions Kavachi Island and I did a quick search and came up with this.
From Wikipedia,
Kavachi is one of the most active submarine volcanoes in the south-west Pacific Ocean.Located south of Vangunu Island in the Solomon Islands, it is named after a sea god of the New Georgia Group islanders, and is also referred to locally as Rejo te Kavachi (“Kavachi’s oven’). The volcano has become emergent and then been eroded back into the sea at least eight times since its first recorded eruption in 1939.
In May 2000, an international research team aboard the CSIRO research vessel FRANKLIN fixed the position of the volcano at 8° 59.65’S, 157° 58.23’E. At that time the vent of the volcano was below sea level, however frequent eruptions were ejecting molten lava up to 70m above sea level, and sulfurous steam plumes up to 500m. The team mapped a roughly conical feature rising from 1,100 m water depth, with the volcano having a basal diameter of about 8 km.
When the volcano erupted in 2003, a 15-meter-high island formed above the surface, but it disappeared soon after. Additional eruptive activity was observed and reported in March 2004 and April 2007.
Kavachi erupting May 14th, 2000.
Barry then looks as CO2 levels, he writes,
Carbon dioxide
If today’s rising carbon dioxide are caused by humans, what caused the dramatic rise in CO2 levels at the dinosaur extinction?
It was a matter of a moment’s search to find this, from Ice Age Now, Home Page here
If today’s rising carbon dioxide are caused by humans, then what caused the dramatic rise in CO2 levels at the dinosaur extinction?
Research shows that there was “a sudden and dramatic rise” in carbon dioxide in the Earth’s atmosphere at the dinosaur extinction of 65 million years ago. A recent report attributes the rise in CO2 levels to an asteroid impact.
See http://news.bbc.co.uk/1/hi/sci/tech/2038599.stm
I disagree. I think today’s rise in CO2 levels can be attributed to our warming oceans. After all, the oceans are known as a carbon dioxide “sink,” especially when the water is cold.
But as the water warms up, it releases CO2 into the atmosphere. This happens in much the same way that a warm bottle of home-brewed root beer will release CO2. And if you give that CO2 no way to escape, the bottle will explode.
We’ve got it backwards. We’ve got cause and effect in reverse.
The CO2 is not causing global warming. Instead, our warming oceans are releasing CO2 into the atmosphere.
It’s not global warming, it’s ocean warming, and it’s leading us into an ice age.
Finally, Barry offers this,
No Global Warming
“Even with needed corrections, data still don’t show the expected signature of global warming,” says Dr. Roy Spencer, Senior Scientist for Climate Studies NASA/Marshall Space Flight Center.
Unfortunately, the URL that Barry included didn’t function. But a quick search on the NASA website came up with this,
Scientists are working to understand why the lower atmosphere isn’t heating up as fast as some global warming models predict.
July 21, 2000 — The question sounds like a Zen koan: How could the globe be warming and not warming at the same time?
That’s the riddle posed to climatologists by satellite and radiosonde data which show that while the Earth’s surface has been warming over the past decades, the lowest layer of the atmosphere shows a weaker warming trend.
The measurements are surprising, because computer simulations of the world’s climate predict that the two lowest layers of the atmosphere — which together form the “troposphere” — should be warming faster than the Earth’s surface.
Read the full article here. It’s well worth reading and concludes with these closing paragraphs,
Current models suffer from several shortcomings.
For example, clouds are not well represented by the models. The resolution of current models is too coarse for features as small as clouds, Spencer said. Yet clouds clearly play a crucial role in climate due to their influence on humidity, precipitation and albedo (the percentage of solar energy reflected back into space as light).
“The role of clouds is still regarded as one of the biggest uncertainties in global warming predictions,” Spencer said.
The ability of plants to remove carbon dioxide from the atmosphere and the role of soils have only recently been added to the models, and scientists aren’t confident yet of how the models portray these factors, Spencer said.
“While we know that vegetation takes up some of the carbon dioxide we generate from burning of fossil fuels, how that sink of carbon will change in the future is still pretty uncertain,” Spencer said.
Climate models are also limited by the computing power available.
“The global models would be much better if computers were much faster,” Spencer said. “Instead, a lot of approximations are made to make the models simple enough to do climate simulations over the whole globe.
“Unfortunately,” Spencer continued, “we know that many of the processes that are crudely represented are quite non-linear, and so have the potential to respond in unexpected ways.”

OK, that’s enough from me for today. Clearly it would take a great time for a layman, such as yours truly, to go through all this material, and more, to determine the truth of it all, to the very best abilities of science. For the verdict on whether man’s increased generation of CO2 in the atmosphere is having a global effect on the global climate should be in the hands of scientists.
Once science has shown cause and effect then, and only then, should politicians endeavour to offer the way forward for society.
Having said that, there is no reason at all for mankind to maintain the present disconnect from Planet Earth. Even if the jury is still well and truly out in terms of the effect of CO2 on the atmosphere, the number of other issues that are just as important for our long-term survival are still prodigious. There’s an old saying in aviation, “If there’s any doubt, there’s no doubt.”

Or what about this?
To dare is to lose one’s footing momentarily. To not dare is to lose oneself. Soren Kierkegaard
Søren Aabye Kierkegaard (b. 1813, d. 1855) was a profound and prolific writer in the Danish “golden age” of intellectual and artistic activity. His work crosses the boundaries of philosophy, theology, psychology, literary criticism, devotional literature and fiction. Kierkegaard brought this potent mixture of discourses to bear as social critique and for the purpose of renewing Christian faith within Christendom. At the same time he made many original conceptual contributions to each of the disciplines he employed. He is known as the “father of existentialism”, but at least as important are his critiques of Hegel and of the German romantics, his contributions to the development of modernism, his literary experimentation, his vivid re-presentation of biblical figures to bring out their modern relevance, his invention of key concepts which have been explored and redeployed by thinkers ever since, his interventions in contemporary Danish church politics, and his fervent attempts to analyse and revitalise Christian faith.
OK, dear readers, from somewhere over who knows where!
We really may be on the verge of a new geological period.
Just a couple of weeks ago, on the 16th May, I wrote an article called The Anthropocene period. It was based on both a BBC radio programme and a conference called “The Anthropocene: A New Epoch of Geological Time?”
So imagine my surprise when I collected this week’s copy of The Economist from my mail-box last Saturday. The cover page boldly illustrated a lead article within, as this picture shows.
US edition, May 28th
The leader is headlined, ‘Humans have changed the way the world works. Now they have to change the way they think about it, too.’ The first two paragraphs of that leader explain,
THE Earth is a big thing; if you divided it up evenly among its 7 billion inhabitants, they would get almost 1 trillion tonnes each. To think that the workings of so vast an entity could be lastingly changed by a species that has been scampering across its surface for less than 1% of 1% of its history seems, on the face of it, absurd. But it is not. Humans have become a force of nature reshaping the planet on a geological scale—but at a far-faster-than-geological speed.
A single engineering project, the Syncrude mine in the Athabasca tar sands, involves moving 30 billion tonnes of earth—twice the amount of sediment that flows down all the rivers in the world in a year. That sediment flow itself, meanwhile, is shrinking; almost 50,000 large dams have over the past half- century cut the flow by nearly a fifth. That is one reason why the Earth’s deltas, home to hundreds of millions of people, are eroding away faster than they can be replenished.
There’s also a video on The Economist website of an interview with Dr. Erle Ellis, associate professor of geography and environmental systems at the University of Maryland. That video link is here.
That Economist lead article concludes,
Recycling the planet
How frightened should people be about this? It would be odd not to be worried. The planet’s history contains many less stable and clement eras than the Holocene. Who is to say that human action might not tip the planet into new instability?
Some will want simply to put the clock back. But returning to the way things were is neither realistic nor morally tenable. A planet that could soon be supporting as many as 10 billion human beings has to work differently from the one that held 1 billion people, mostly peasants, 200 years ago. The challenge of the Anthropocene is to use human ingenuity to set things up so that the planet can accomplish its 21st-century task.
Increasing the planet’s resilience will probably involve a few dramatic changes and a lot of fiddling. An example of the former could be geoengineering. Today the copious carbon dioxide emitted to the atmosphere is left for nature to pick up, which it cannot do fast enough. Although the technologies are still nascent, the idea that humans might help remove carbon from the skies as well as put it there is a reasonable Anthropocene expectation; it wouldn’t stop climate change any time soon, but it might shorten its lease, and reduce the changes in ocean chemistry that excess carbon brings about.
More often the answer will be fiddling—finding ways to apply human muscle with the grain of nature, rather than against it, and help it in its inbuilt tendency to recycle things. Human interference in the nitrogen cycle has made far more nitrogen available to plants and animals; it has done much less to help the planet deal with all that nitrogen when they have finished with it. Instead we suffer ever more coastal “dead zones” overrun by nitrogen-fed algal blooms. Quite small things, such as smarter farming and better sewage treatment, could help a lot.
For humans to be intimately involved in many interconnected processes at a planetary scale carries huge risks. But it is possible to add to the planet’s resilience, often through simple and piecemeal actions, if they are well thought through. And one of the messages of the Anthropocene is that piecemeal actions can quickly add up to planetary change.
We are living in interesting times!
Finally, more of Dr. Ellis may be watched on the following YouTube video.
President John F. Kennedy's May 25, 1961 Speech before a Joint Session of Congress
On the 25th May, 1961, President John Kennedy summoned a joint session of Congress and asked America to commit itself to a goal – that of landing a man on the moon and returning him safely to Earth before the decade was out.
There’s a good link on the NASA site to the speech.
MY print column this week notes that it is half a century next week since John Kennedy called for sending a man to the moon and returning him safely to Earth. The bottom line, I think:
If we can send a man to the moon, people ask, why can’t we [fill in the blank]? Lyndon Johnson tried to build a “great society”, but America is better at aeronautical engineering than social engineering. Mr Obama, pointing to competition from China, invokes a new “Sputnik moment” to justify bigger public investment in technology and infrastructure. It should not be a surprise that his appeals have gone unheeded. Putting a man on the moon was a brilliant achievement. But in some ways it was peculiarly un-American—almost, you might say, an aberration born out of the unique circumstances of the cold war. It is a reason to look back with pride, but not a pointer to the future.
Before moving to the thrust of this article, let me say that of the few things that I miss now living in Arizona, British draft beer and BBC Radio 4 are top of the list. Radio 4 have long broadcast a splendid 30-minute summary of science matters under the banner of Material World. It was the broadcast on May 12th that had a very powerful except that I will present here. The programme is available to listen online. This is how the BBC wrote up the summary,
Researchers from all over the world and various disciplines gathered together in London for a conference called “The Anthropocene: A New Epoch of Geological Time?” The term “Anthropocene” was coined by Professor Paul Crutzen of the Max Planck Institute in 2002 to suggest human activity has had such an irreversible affect on our planet, that we have entered into a new geological period, influenced by humans. The conference aimed to discuss the various research projects studying the Anthropocene, as well as to discuss whether or not it should be formalised as a geological “Epoch”. What actually is the Anthropocene, why are so many disciplines researching it and what difference will it make if it is formalized? Quentin finds out from Leicester University geologist Dr. Jan Zalasiewicz, and ecologist Professor Erle Ellis from the University of Maryland, Baltimore County.
Elsewhere on the BBC website, a fuller summary of the conference was written up by Howard Falcon-Lang, Royal Holloway, University of London. I have taken the liberty of publishing that summary, minus the photographs, below, simply because it’s so important a read.
Anthropocene: Have humans created a new geological age?
By Howard Falcon-Lang Royal Holloway, University of London, 10th May 2011
Human civilisation developed in a cosy cradle.
Over the last 11,700 years – an epoch that geologists call the Holocene – climate has remained remarkably stable. This allowed humans to plan ahead, inventing agriculture, cities, communication networks and new forms of energy.
Some geologists now believe that human activity has so irrevocably altered our planet that we have entered a new geological age.
This proposed new epoch – dubbed the Anthropocene – was discussed at a major conference held at the Geological Society in London on Wednesday. Yet some experts say that defining this “human age” is much more than about understanding our place in history. Instead, our whole future may depend on it.
The term, the Anthropocene, was coined over a decade ago by Nobel Laureate chemist, Paul Crutzen. Professor Crutzen recalls: “I was at a conference where someone said something about the Holocene. I suddenly thought this was wrong. The world has changed too much. No, we are in the Anthropocene. I just made up the word on the spur of the moment. Everyone was shocked. But it seems to have stuck.”
But is Professor Crutzen correct? Has the Earth really flipped into a new geological epoch – and if so, why is this important?
Back to the beginning
Dr Jan Zalasiewicz of the University of Leicester is one of the leading proponents of the Anthropocene theory. He told BBC News: “Simply put, our planet no longer functions in the way that it once did. Atmosphere, climate, oceans, ecosystems… they’re all now operating outside Holocene norms. This strongly suggests we’ve crossed an epoch boundary.” Dr Zalasiewicz added: “There are three ideas about when the Anthropocene began. Some people think it kicked off thousands of years ago with the rise of agriculture, but really those first farmers didn’t change the planet much. Others put the boundary around 1800. That was the year that human population hit one billion and carbon dioxide started to significantly rise due to the burning of fossil fuels in the Industrial Revolution,” he explained. Dr Zalasiewicz continued, “However, the really big changes didn’t get going until the end of the Second World War – and that’s another candidate for the boundary.”
To formally define a new epoch, geologists must show how it can be recognised in the layers of mud that will eventually form rocks. As it turns out, there is enormous practical advantage in fixing 1945 as the beginning of the Anthropocene.
“1945 was the dawn of the nuclear age,” explained Dr Zalasiewicz. “Sediments deposited worldwide that year contain a tell-tale radioactive signature from the first atom bomb tests in the States”. So, thousands of years from now, geologists (if any still exist) will be able to place their finger on that very layer of mud.
Extraordinary times?
Nonetheless, the choice of 1945 for start of the Anthropocene is much more than just convenient. It coincides with an event that Professor Will Steffen of the Australian National University describes as the “Great Acceleration”. Professor Steffen told the BBC: “A few years ago, I plotted graphs to track the growth of human society from 1800 to the present day. What I saw was quite unexpected – a remarkable speeding up after the Second World War”.
In that time, the human population has more than doubled to an astounding 6.9 billion. However, much more significantly, Professor Steffen believes, the global economy has increased ten-fold over the same period.
“Population growth is not the big issue here. The real problem is that we’re becoming wealthier and consuming exponentially more resources,” he explained.
This insatiable consumption has placed enormous stresses on our planet. Writing in the prestigious journal Nature, Professor Steffen and colleagues recently identified nine “life support systems” essential for human life on Earth. They warned that two of these – climate and the nitrogen cycle – are in danger of failing, while a third – biodiversity – is already in meltdown.
“One of the most worrying features of the Great Acceleration is biodiversity loss,” Professor Steffen said. “Species extinction is currently running 100 to 1000 times faster than background levels, and will increase further this century. When humans look back… the Anthropocene will probably represent one of the six biggest extinctions in our planet’s history.” This would put it on a par with the event that wiped out the dinosaurs.
But perhaps more alarming is the possibility that the pronounced global warming seen at the start of the proposed Anthropocene epoch could be irreversible. “Will climate change prove to be a short-term spike that quickly returns to normal, or are we seeing a long term move to a new stable state?” asked Professor Steffen. “That’s the million dollar question.”
If the Anthropocene does develop into a long-lived period of much warmer climate, then there may be one very small consolation: the fossil record of modern human society is likely to be preserved in amazing detail.
Dr Mike Ellis of the British Geological Survey told BBC News: “As a result of rising sea level, scientists of the future will be able to explore the relics of whole cities buried in mud”.
Preserved buildings
In New Orleans, large areas of the city are already below sea level. The disastrous combination of rising sea level and subsidence of the Mississippi Delta on which it is built suggest that it will succumb at some point in the future. Although the Intergovernmental Panel on Climate Change (IPCC) predicts less than a metre of sea level rise over the next 90 years, more than five metres of sea level rise is possible over the coming centuries as the Greenland and West Antarctic ice caps melt.
Sea level rise of this magnitude will mean that the lower storeys of buildings will be preserved intact. Such “urban strata will be a unique, widespread and easily recognisable feature of the sedimentary deposits of the human age”, Dr Ellis commented.
Geologists of the future may also hunt for other, more unusual, “markers” of the Anthropocene epoch, such as the traces of plastic packaging in sediments.
But geologists like Dr Mark Williams from the University of Leicester hold much more serious concerns: “One of the main reasons we developed the Anthropocene concept was to quantify present-day change and compare it with the geological record,” he explained. “Only when we do so, can we critically assess the pace and degree of change that we’re currently experiencing.”
Dr Williams added that while the Anthropocene has yet to run its course, “all the signs are that the human age will be a stand-out event in the 4.5 billion year history of the Earth”.
I’m taking a little gamble that the owners of the copyright in the following article will not mind the complete re-publishing of this piece.
While I have practically zero knowledge of the geology of much of the USA living here close to the Mogollon Rim makes it almost impossible not to sense the ageless beauty of the surrounding hills and mountains. Anyway, this article was found on the Arizona Geology website. It is called Putting Earth Science Back in its Place, written by STEVEN SEMKEN of ARIZONA STATE UNIVERSITY.
The ancient landscape of Arizona
One of the most universal and fundamental things that humans do is to make places. We do this by sensing and experiencing the space around us, and attaching meanings to parts of it: here is a beautiful mountain, here is where my house is, here is where we have found copper, here is where my ancestors lived. The meanings that we affix to places can be aesthetic, ceremonial, historic, practical, and mythical, as well as scientific. Humans develop emotional attachments to meaningful places, sometimes to the point of making significant personal sacrifices to preserve or protect them. The combination of meanings and attachments that connect us to places is called the sense of place.
We study and teach about Earth through its places. From Monument Valley to Organ Pipe, the landscapes of Arizona are set with places that are not only great geological exemplars, but meaningful to people for all kinds of reasons. It is only human for us to become interested in these diverse place meanings even as we explore our surroundings scientifically. Our students may also have, or can be encouraged to develop, rich senses of these places—particularly ones that are relevant to their personal interests, family experiences, or cultural backgrounds. This is the nature ofplace-based teaching, which encourages students to explore, and become involved in, local environments and communities. Urban places are just as meaningful, and can be just as instructive, as rural or remote places.
It is not simply teaching about the geology of a place such as Grand Canyon or the Río Salado Valley. It is finding ways for your students to experience the place: if possible by bringing them there, but alternatively by bringing them local rock specimens, images, maps, and readings to investigate, or enabling them to explore virtually using Google Earth. It is also helping them to become moreinvested in local places: by being able to explain how they get their weather, drinking water, fuel, and electrical power; by doing a community-service project; by creating art that celebrates the beauty of land and environment. And authentically place-based teaching and learning are as trans-disciplinary as place meanings themselves are. Here are reason and motivation for Earth science teachers to collaborate with their colleagues in life sciences, geography, history, language, literature, and so on, to develop ways to explore and understand the natural and cultural landscapes of Arizona across the curriculum.
Why is this important? On one hand, cultural forces such as the pervasiveness and popularity of digital entertainment and the homogenizing effects of global commerce conspire against student and community interest in local places and concerns. There is mounting research and anecdotal evidence that children and families spend less time outdoors. To be oblivious to the importance of local places is to forego opportunities to learn from them and protect them from environmental and cultural degradation. On the other hand, right here in Arizona we are already faced with a number of what many scientists and policymakers have labeled “grand challenges” to sustainability if not human existence, including depletion of water resources, lessened biodiversity, declining air quality, continued dependence on fossil energy, and climate change. Place-based teaching is an appropriate response. And it is intellectually and emotionally delightful to reacquaint yourself and your students with the places of home.

Last Wednesday, I set out to explain why the blog is called Learning from Dogs. If you missed that then it is here. The focus was on the very special relationship between man and dog that goes back thousands of years. It has been a critically important relationship for both species.
But there is another aspect to this Blog, as follows: The relationship between dogs and man goes back thousands of years. The theory is that dogs were domesticated between 15,000 and 40,000 years ago although DNA evidence suggests dogs split away from the grey wolf around 100,000 years ago. Certainly, the dog was the first animal to be domesticated by man. In fact, some archaeologists speculate that man could not have been a successful ‘hunter-gatherer’ without his relationship with the dog and thus been able to progress to farming the earth for food.
The relationship between Planet Earth and man, as in H. sapiens, goes back around 200,000 years. There is little doubt that most people, even with a minimum of awareness about the world that we live in, are deeply worried. On so many fronts there are forbidding and scary views. It feels as though all the certainty of past times has gone; as if all the trusted models of society are now broken. Whether we are talking politics, economics, employment or the environment, nothing seems to be working.
Why is this? What’s the cause?
It would be easy to condemn man’s drive for progress and an insatiable self-centredness as root causes. But it’s not the case.
The root cause is clear. It is this. How mankind has developed is the result of mankind’s behaviours. All of us behave in many ways that are hugely damaging to the survival of our species. It is likely that these behaviours are little unchanged over thousands of years.
But 2000 years ago, the global population of man was just 300 million.
Twelve-hundred years later, in 1800, it was 1 billion. In 1927, just 127 years later, the two-billionth baby was born. In 1960, only 33 years on, the three-billionth baby. (Remember the moon landing in 1969? Well, of course you do! There were about three and a half billion people on the planet!)
Just 16 years on, in 1974, the four-billionth baby was born. In 1987, 13 years later, five billion. Around October 1999, the sixth-billionth baby was born!
It’s trending to a billion every decade. 100 million population growth every year, or about 270,000 every single day!
Combine man’s behaviours with this growth of population and we have the present situation. A totally unsustainable situation disconnected from the planet that supports us.
The only viable solution is to amend our behaviours. To tap into the powers of integrity, self-awareness and mindfulness and change our game.
We all have to work with the fundamental, primary relationships we have with each other and with the planet upon which we all depend. We need a level of consciousness with each other and with the living, breathing planet that will empower change. We need spiritual enlightenment on a grand scale.
That’s why we have so much to learn from dogs. They are man’s best friend. They are man’s oldest friend. They have a relationship with us that is very special; almost certainly telepathic. They can show us how we need to live our lives.
Man's oldest, and wisest, friend.
That’s the real reason why this Blog gets written. Phew! Glad that’s off my chest!
It struck me recently that many of you readers that come to Learning from Dogs on a regular basis, say, over the last 18 months, may not be clear as to why it’s called what it is, and the deeper issues behind the name.
First, the name. Quite a few years ago I was sitting chatting with Jon Lavin, the co-founder of the Blog, in his home in South-West England. My German Shepherd, Pharaoh (that’s him on the home page) was sleeping on the floor while Jon and I were nattering about the works of Dr David Hawkins of Veritas Publishing. Jon mentioned that David Hawkins had measured the consciousness of dogs and that they came out about 205. In other words they were integrous creatures and firmly on the truthful side of the boundary between truth and falsehood.
I was fascinated by that idea. Later, back at my home, less than an hour away from Jon’s house, I was idly looking at domain names that were available, and imagine my glee when I discovered that learningfromdogs (dot) com was free. It was rapidly grabbed.
A rather chaotic period of my life descended upon me but the notion that we have much to learn from dogs stayed with me. Much later, when I was happily settled with Jean, the vision and purpose of the Blog got me under way. The first post was published on 15th July, 2009.
The ideas behind the theme that dogs have an extraordinary relationship with man is contained in a very early piece written for the Blog back in July 19th, 2009. That article is called Dogs and integrity. But nothings stays still. In that piece, I wrote,
Because of this closeness between dogs and man, we (as in man!) have the ability to observe the way they live. Now I’m sure that scientists would cringe with the idea that the way that a dog lives his life sets an example for us humans, well cringe in the scientific sense.
However, on Sunday evening we watched a video from PBS that showed that scientists are now taking a very close interest in dogs and why they have such a special relationship with man, perhaps even a critical part in enabling man to prosper as hunter-gatherers. Here’s a preview of that video programme.
Unfortunately, the video is not freely available from PBS. However, it was based on the BBC Horizon programme, The Secret Life of the Dog, which I wrote about back in the 25th January, 2011. (The YouTube link on that post appears to have been curtailed.)
Luckily there are a couple of options to watch this fascinating and very revealing documentary. You can either watch it in sections from YouTube, the first 10 minutes is below, or you can watch it in full, if you don’t mind some Chinese translations here. Your choice.
That’s enough for today, I shall return to this theme next week.
A wonderful tribute to Yuri Gagarin and all his team.
When I recently wrote of it being 41 years since Swigert on board Apollo 13 transmitted “Okay, Houston, we’ve had a problem here.” I also included a closing reflection as follows,
Finally, this Post is published, not only on the 41st anniversary of that memorable Apollo Flight but the day after the 50th anniversary of Yuri Gagarin’s first flight of a human into space, the 12th April, 1961.
Coincidentally, our favourite documentary film website, Top Documentary Films, featured on April 14th the new film First Orbit. We watched the film that night. It was a most unusual format for a film, yet a most haunting experience. Watching the credits, it then became clear that the film was a co-operative venture made especially for the 50th anniversary of that remarkable, historic flight.
Of course, had I previously been aware of the venture and this remarkable film then it would have been promoted on Learning from Dogs in good time before the anniversary date. However, better late than never!
Indeed, there is a dedicated website in recognition of this First Orbit. Here’s the background to the film,
April 12th 1961 – Yuri Gagarin is about to see what no other person has seen in the history of humanity – the Earth from space. In the next 108 minutes he’ll see more than most people do in a lifetime. What sights awaited the first cosmonaut silently gliding over the world below? What was it like to view the oceans and continents sailing by from such a height?
By matching the orbital path of the Space Station, as closely as possible, to that of Gagarin’s Vostok 1spaceship and filming the same vistas of the Earth through the new giant cupola window, astronaut Paolo Nespoli, and documentary film maker Christopher Riley, have captured a new digital high definition view of the Earth below, half a century after Gagarin first witnessed it.
Weaving these new views together with historic, recordings of Gagarin from the time, (subtitled in Englsih) and an original score by composer Philip Sheppard, we have created a spellbinding film to share with people around the world on this historic anniversary.
The music in the film is most beautiful, quite moving. Here’s the background to the music from the First Orbit website,
First Orbit’s producer Christopher Riley first worked with Philip in 2006 on the Sundance Award winning feature documentary film ‘In the Shadow of the Moon‘ and since then Philip had been working on a new suite of music inspired by spaceflight.
“We’d been working with some of these tracks on another project” says Chris, “and we suddenly realised how perfectly they could compliment ‘First Orbit’ as well. We contacted Philip to ask his permission to use them, only to find that his entire Cloud Song album was already in orbit onboard the International Space Station!”
“NASA astronaut Cady Coleman, had them on her iPod” says Philip. “Her husband Josh Simpson is a friend of mine and they’d listened to a lot of my music together before she left, so I made up a playlist for her!”
Quite by coincidence Cady had been listening to the music in ‘First Orbit’ at one end of the Space Station whilst European Space Agency astronaut Paolo Nespoli was shooting for the film at the other end, without either of them knowing the connection!
Back on Earth Chris and the film’s editor Stephen Slater took Philip’s tracks from Cloud Song and weaved them together with Paolo’s new views of the Earth to create the different moods of the film; from the first views of snowy Siberia to the darkness of night over the Pacific Ocean and the homecoming over Africa, as Gagarin starts to re-enter the atmosphere.
The result is a mesmerising combination of imagary and music which we hope convey the spectrum of emotions which no doubt went through Yuri’s mind as he gazed down upon the Earth.
Finally, here’s the film. It’s an hour and thirty-nine minutes and, as I said, an unconventional film experience. But if any part of you either remembers the event or wonders what it was like, those 50 years ago, then find somewhere out of reach of interruptions and watch the film.
On April 12th, I introduced to you, dear reader, the philosopher, Alain de Botton. I promised that I would soon give you more.
On Top Documentary Films, there are links to all six parts of a series on philosophy presented by this popular British philosopher featuring six thinkers who have influenced history, and their ideas about the pursuit of the happy life.
The first part is about Socrates; Socrates and self-confidence. But before linking to that specific programme, a little about this enigmatic man, Socrates, who lived about 2,500 years ago (469–399 B.C.E). Here’s an extract from the Stanford Encyclopaedia of Philosophy.
The philosopher Socrates remains, as he was in his lifetime (469–399 B.C.E.),an enigma, an inscrutable individual who, despite having written nothing, is considered one of the handful of philosophers who forever changed how philosophy itself was to be conceived. All our information about him is second-hand and most of it vigorously disputed, but his trial and death at the hands of the Athenian democracy is nevertheless the founding myth of the academic discipline of philosophy, and his influence has been felt far beyond philosophy itself, and in every age. Because his life is widely considered paradigmatic for the philosophic life and, more generally, for how anyone ought to live, Socrates has been encumbered with the admiration and emulation normally reserved for founders of religious sects—Jesus or Buddha—strange for someone who tried so hard to make others do their own thinking, and for someone convicted and executed on the charge of irreverence toward the gods. Certainly he was impressive, so impressive that many others were moved to write about him, all of whom found him strange by the conventions of fifth-century Athens: in his appearance, personality, and behavior, as well as in his views and methods.
Full entry may be read here, and very interesting it is, by the way.
Anyway, back to the programme from Alain de Botton. The part on Socrates is introduced thus,
Why do so many people go along with the crowd and fail to stand up for what they truly believe? Partly because they are too easily swayed by other people’s opinions and partly because they don’t know when to have confidence in their own.
