Close neighbour, Dordie, sent me an email with a link to a recent item that was broadcast on CBS.

For thousands of blind athletes across the country, just setting foot out the door can be a huge challenge. Now one special dog is helping his owner not just walk out the door, but run. Only on “CBS This Morning,” Barry Petersen reports on the extraordinary story of one man’s journey to find the perfect running mate.
Richard and Klinger, and all those who made it happen, Jean and I salute you!
The vastness of the seas and the immensity of their influence over all of us.
This is an introduction, a rather long one I’m warning, to a republication of a recent post by Patrice Ayme. An introduction that offers a deeply personal memory of the Atlantic ocean.
Many years ago, I spent 5 years living on a boat; a wonderful heavy-displacement ocean-going yacht of a type known as a Tradewind 33.
My home for five years – Tradewind 33: Songbird of Kent.
There is a place in my mind to which I can so easily travel; a memory of a dark night out in the Atlantic ocean one time in the Autumn of 1969. But first let me set the scene from almost fifty years ago.
The call of the open ocean
Those first few hours were utterly absorbing as I went through the whole business of clearing the yacht harbour at Gibraltar and heading out to the South-West hugging this unfamiliar coastline of Southern Spain. It was tempting to move out to deeper waters but the almost constant flow of large ships through the Straights of Gibraltar soon quashed that idea. Thankfully, the coastal winds were favourable for me and my single-masted sailing yacht.
After such a long time sailing in the relatively confined waters of the Mediterranean, it was difficult for me to imagine that in a few hours time the southern-most point of Spain would pass me by and the vastness of the Atlantic ocean would be my home for the next few weeks.
Soon the city of Tarifa was past my starboard beam and the Spanish coastline was rapidly disappearing away to the North-West. The horizon ahead of me was already approaching 180 degrees of raw, open ocean. There was just a flicker of a thought that whispered across my mind: “Oh Paul, what have you gone and done” as slowly but persistently the coastlines of Spain to the North and of Africa to the South became more and more distant and fuzzy. It was at 15:30 that I made an entry in my yacht’s log: “No land in sight in any direction!”
Now was the time to make sure that my bunk was made up, flashlights to hand, and my alarm clock ready and set. Alarm clock? Set to go off every twenty minutes during the night! For this was the only way to protect me and my yacht from being hit by one of those gigantic container ships that seemed to be everywhere. It took at least twenty minutes from the moment a ship’s steaming lights appeared above the horizon to crossing one’s path!
It was in the early hours of my first morning alone at sea, when once again the alarm clock had woken me and I was looking around an ocean without a single ship’s light to be seen that more of Les’ words (see footnote) came to me. I remembered asking Les: “What’s the appeal of sailing?” Les replied without a moment’s hesitation: “It’s the solitude. When you’re out at sea on your own, there’s no government or bankers to worry about. You’re not responsible to anyone but yourself.”
Yes, I could sense the solitude that was all around me but it was an intellectual sense not an emotional one. That would come later. Inside, I was still afraid of what I had let myself in for.
Remarkably quickly however, the pattern of solo life aboard a thirty-three-foot yacht became my world. Frankly, it staggered me as to how busy were my days. Feeding myself, navigating, trying to forecast the winds, staying in touch with other yachties via the short-wave radio, keeping the boat tidy and a zillion other tasks meant the first few days and nights just slipped by.
But it was a sight on my fourth night at sea that created the memory that would turn out to remain with me for all my life. The memory that I can go to anytime in my mind.
That fourth night I was already well into the routine of waking to the alarm clock, clipping on my harness as I climbed up the three steps that took me from my cabin into the cockpit, scanning the horizon with my eyes, checking that the self-steering had the boat at the correct angle to the wind and then, if no ships’ lights had been seen, slipping back down into my bunk and sleeping for another twenty minutes. Remarkably, I was not suffering from any long-term tiredness during the day.
It was a little after 3am that fourth night when the alarm clock had me back up in the cockpit once again. Then it struck me.
Songbird was sailing beautifully. There was a steady wind of around ten knots from the south-east, almost a swell-free ocean, and everything set perfectly. Not a sign of any ship in any direction.
Then I lifted my eyes upwards. There was not a cloud in the night sky, not a single wisp of mist to dim a single one of the million or more stars that were above my head. For on this dark, moonless night, so far removed from any shore-based light pollution, the vastness, yet closeness of the heavens above was simply breath-taking. I was transfixed. Utterly unable to make any rational sense of this night splendour that glittered in every direction in which I gazed. This dome that represented a vastness beyond any meaning other than a reminder of the magic of the universe.
This magic of the heavens above me that came down to touch the horizon in all directions. Such a rare sight to see the twinkling of stars almost touching the starkness of the ocean’s horizon at night. A total marriage of this one planet with the vastness of outer space.
I heard the alarm clock go off again and again next to my bunk down below. But I remained transfixed until there was a very soft lightening of the skyline to the east that announced that another dawn was on its way.
I would never again look up at the stars in a night sky without being transported back to that wonderful night and the memory of a lonely sea and sky.
I did warn you it would be a long introduction!

Non-Linear Cold Blob Rising Over North Atlantic
The reason life survived on Earth for so long, and blossomed into animals, and now mind, is that the planet is equipped with homeostatic mechanisms (homeo means similar in Greek, and stasis, standing still). However, those mechanisms tend to be geological.
Human civilization is now having an impact on the biosphere of a violence probably never seen before. The changes are faster than what geology, or even life, can accommodate.
Some will brandish the impact of the Yucatan asteroid, and claim that was worse; however that’s just a theory: the biosphere was clearly under stress at the time from the Deccan Traps eruptions, and had been under that stress for hundreds of thousands of years, if not millions. At its worst, the Asteroid was just the straw which broke the Camel’s back.
2015 will be the warmest year since the end of the Eemian, 115,000 years ago. So why are record low temperatures appearing just south of Iceland? Yes, record lows, lower than ever recorded.
While The Rest Of Planet Is At Record Warmth, Off Iceland, Record Colds Are Achieved!
That was fully expected, and a demonstration of Non-Linearity of the incipient global warming. A phenomenon is linear when it looks like a line. Global warming is not going up like a line, as some places are warming at a rate ten times higher than the average, and some regions are cooling (and some are cooling spectacularly, off Iceland and some seas around Antarctica, for reasons related to warming).
The Dryas events were extremely fast and pronounced cooling events which happened several times during the period 10,000 years to 15,000 Before Present. Some lasted around a millennium, others, just a century. They vanished as fast as they came. They are named after a tundra flower, the Dryas. In Scandinavia forests were replaced by tundra graced with Dryas (hence the name). In Britain, average temperature collapsed to minus 5 degree Celsius, and glaciers formed at elevation.
These spastic events of drastic cooling, while, overall, de-glaciation was going on, long remained a mystery. Overall, the great glaciation which had brought glaciers down to New York, was on its way out, the planet was globally, irresistibly warming. So why would temperatures collapse in some places around Greenland by 15 degrees Celsius? The solution to the Dryas events’ spastic glaciation riddle? The same as always! Warming is non-linear.
What’s the theory? The details are uncertain, but we know that the Gulf Stream (aka the North Atlantic “Conveyor”) shorted, literally: analyses of deep sea sediments have shown this. The conveyor sends an enormous current of warm tropical waters northward.
When the warm tropical waters become very cold between Iceland and Spitzbergen, they sink to the bottom of the sea, and head south. This sinking, plus the pushing by trade winds in the tropics, is what provides the energy of the Gulf Stream.
However, if the warm tropical waters are capped by a very cold, but light sweet(er) water lid, they will get cold early, and sink before Iceland. This is what happened in the Dryas events.
And It Is Happening Again, Albeit On A Smaller Scale.
Was it in response to a sudden influx of fresh water from Lake Agassiz and deglaciation in North America, and Greenland? Sudden freezing there would have removed the freshwater lid, hence the brutal switchback to warming after the brutal cooling. By the way, the sea level rising speed responded quickly, by a factor of three. After the typical Dryas cooling, oceanic rise rebounded to 18 millimeter per year right away (this shows that those who expect a slow rise of sea level rise are deluding themselves, or, more to the point, are trying to delude us!)
Nowadays a Dryas-like mechanism would have to rest on the melting of Greenland alone (that’s the only place with significant ice). This is, of course, insufficient, but summer 2015, cool and rainy over the northern North Atlantic is evidence that the effect is on. Scientific analysis confirms it. See: “Exceptional Twentieth Century Slow Down of Atlantic Ocean Overturning Circulation” (Nature, 23 March, 2015).
The exact nature of what is going on at this point is a matter of debate among experts. What is sure is that something is going on.
The Atlantic Conveyor Is A Subtle Thing, Yet Dominates Glaciation In The Arctic.
A similar situation beckons in Antarctica, where ice shield melting creates a freshwater lid all around which in turn freeze, extending the ice cap in the Austral winter.
When considering nonlinearity, subtlety and surprises are of the essence. This is true in physics, as it is in psychology, history, or politics.
And the morality in all this? The USA has played god. The European Union made a honest to goodness effort to reduce CO2 emission, while the USA, paying lip service to the opposite of what it was doing went right ahead, with its factory, the Plutocratic Republic of China, to use and abuse fossil fuels as never before.
So now what? Is god still American, as usual? At first it seems so: the USA started to frack massively and massive amounts of fossil fuels were extracted from the USA’s generous soil. When American companies tried the same in Poland, it failed: the underground god (Pluto?) did not cooperate: Polish soil is adverse to fracking.
Here comes the punchline: sea level has been rising fast along the Eastern seashore of the USA. Actually, three to four times faster than the world average. That’s more than one centimeter per year.
Why? Imagine a traffic jam. Or rather a crash ahead: things come to a halt, cars, water piles up behind. Maybe the Washington politicians will soon have to learn to swim, and not just against the tide of world public opinion.
The USA is going to be punished with its own instruments. Meanwhile 20 countries formed the V20, a group of twenty countries whose existence is immediately threatened by global warming, although they caused it not.
Footnote: The Les referred to is Les Powells, the yachtsman who sailed solo three times around the world. He and I became good friends when we met up at Larnaca Marina in Cyprus.
Last Monday, Jean and I had been living here in Merlin, Oregon for three years.
Why I am explaining this is because my day yesterday ended up being so busy that I ran out of time to focus on writing a fresh new post for you good people.
Thus, I decided to repost something that I published that first week we moved in to our Merlin home. Namely, a post published on the 16th October, 2012 under the heading of The death of the USA?.
So my apologies for you dear readers that recall this from three years ago, and welcome to the many new followers of this place that have signed up since then.

“The reports of my death are greatly exaggerated!”Mark Twain.
Mark Twain
The Mark Twain quotation after hearing that his obituary had been published in the New York Journal.
Mistaken publications of obituaries aren’t as rare as you might expect. A recent example is of Dave Swarbrick, the British folk/rock violinist, who was killed off mistakenly by the Daily Telegraph in April 1999 when they reported that his visit to hospital in Coventry had resulted in his death. He did at least get the opportunity to read a rather favourable account of his life, not something we all get to do, and to deliver the gag “It’s not the first time I have died in Coventry”.
So why have I opened with this quote from Mark Twain? Read on and I hope all will be clear.
A little under a week ago, I published a couple of posts that proposed that the United States of America is an empire in decline. The first was What goes up? and the second Might just come down! As a Brit, I well know that aspect of British history!
However a recent conversation with a friend of many years back in England, who has also been a shrewd and wise entrepreneur for longer than I care to remember, argued that the evidence for the ‘end of the USA’ could be challenged.
He cited five reasons why he thought the USA would remain, more or less, in its dominant position. They were:
Spirit of innovation
Relaxed labour laws
The importance of Mexico
The uncertainty of China in terms of the next ’empire’
The likely energy self-sufficiency for the USA in the near-term.
So let me expand on each of those points.
Spirit of innovation
Let me quote from an article in TIME Magazine of the 5th June, 2011,
Innovation is as American as apple pie. It seems to accord with so many elements of our national character — ingenuity, freedom, flexibility, the willingness to question conventional wisdom and defy authority. But politicians are pinning their hopes on innovation for more urgent reasons. America’s future growth will have to come from new industries that create new products and processes. Older industries are under tremendous pressure. Technological change is making factories and offices far more efficient. The rise of low-wage manufacturing in China and low-wage services in India is moving jobs overseas. The only durable strength we have — the only one that can withstand these gale winds — is innovation.
Now there are plenty who would argue both ways in terms of the future innovation potential for the USA, as a recent article in The Atlantic does, see American Innovation: It’s the Best of Times and the Worst of Times. But the spirit of innovation will, nonetheless, be a powerful economic potential for the USA for many years to come.
Relaxed labour laws.
Definitely an area that I have little knowledge of except for the subjective notion that compared to many other nations, the laws in the USA are much less of a restraint on economic productivity than elsewhere.
The importance of Mexico.
The importance in the context of providing the USA with a source of cheaper manufacturing facilities. My English friend thought that this was a significant competitive advantage for the USA. Now, as it happens, we had a couple staying with us over the week-end of the 6th/7th October. The husband is a senior manager of Horst Engineering, an American firm based in Guaymas, Sonora County, Mexico. Here’s a picture from their website,
We are a contract manufacturer of precision machined components and assemblies for aerospace, medical, and other high technology industries. Our core processes include Swiss screw machining, turning, milling, thread rolling, centerless grinding, and assembly. Our extensive supply chain offers our customers a full service logistics solution for managing their precision product requirements. We are ISO9001:2008 and AS9100 registered and proud of our 66 year, three-generation legacy of quality and performance.
I was told that many American and British firms were using Mexico rather than China for a number of reasons. Not least because Chinese suppliers require full payment before shipment. Plus that taking into account that financial aspect together with shipping costs and other logistical issues, China wasn’t as ‘cheap’ over all. Here’s a recent announcement from Rolls Royce,
Rolls-Royce plans new Sonora hub
The burgeoning aerospace industry in Guaymas had its efforts validated recently when the venerable Rolls-Royce chose it as the site for its newest global purchasing office.
Surrounded by several of its aerospace manufacturing suppliers, London-based Rolls-Royce will move into a Guaymas industrial park owned by Tucson-based The Offshore Group to develop a supply hub for commercial jets and military aircraft around the globe.
“Rolls-Royce has very robust booking orders for the next 10 years,” said Joel Reuter, director of communications for Rolls-Royce in North America. “We need to double our production.”
Because a number of Rolls-Royce suppliers already operate in Guaymas, the city was a logical choice, Reuter said.
The uncertainty of China in terms of the next ’empire’
The point made in terms of China taking over ’empire’ status from the USA, as Simon Johnson argues over at Baseline Scenario, is countered by the fact that politically China is an unknown quantity. Until China endorses some form of democratic process, that unknowingness is not going to disappear.
The likely energy self-sufficiency for the USA in the near-term.
I can’t do better than to ask you to watch this video! Just 27-minutes long, it is a very interesting review of the energy future of the USA.
As the TED website suggests in terms of why you should listen to Amory Lovins,
Amory Lovins was worried (and writing) about energy long before global warming was making the front — or even back — page of newspapers. Since studying at Harvard and Oxford in the 1960s, he’s written dozens of books, and initiated ambitious projects — cofounding the influential, environment-focused Rocky Mountain Institute; prototyping the ultra-efficient Hypercar — to focus the world’s attention on alternative approaches to energy and transportation.
His critical thinking has driven people around the globe — from world leaders to the average Joe — to think differently about energy and its role in some of our biggest problems: climate change, oil dependency, national security, economic health, and depletion of natural resources.
So, don’t know about you, but I found those five points deeply convincing. How about you? Are the reports of the death of the USA greatly exaggerated? Do leave a comment.
ooOOoo
Now some three years later on, these five factors still seem to be valid.
Exploring the range of emotions felt and displayed by our dogs.
Like so many bloggers, I subscribe to the writings of many others. Indeed, it’s a rare day when I don’t read something that touches me, stirring up emotions across the whole range of feelings that we funny humans are capable of.
Such was the case with a recent essay published on Mother Nature Network. It was about dogs and whether they are capable of complex emotions. Better than that, MNN allow their essays to be republished elsewhere so long as they are fully and properly credited.
Exactly what emotions do dogs feel, and are they capable of all the same emotions as humans? (Photo: Pressmaster/Shutterstock)
Joy, fear, surprise, disgust, sadness. These are the basic emotions dogs feel that are also easy enough for humans to identify. But what about more complex emotions?
Many dog owners are convinced their dogs feel guilty when they’re caught misbehaving. In the same way, many owners are sure their dogs feel pride at having a new toy or bone. But it gets tricky when you assign these sorts of emotions to a dog. These are definitely emotions felt by humans, but are they also felt by dogs?
(see footnote)
Why we question the presence of complex emotions is wrapped up in the way we get to those emotions. The American Psychological Association explains, “Embarrassment is what’s known as a self-conscious emotion. While basic emotions such as anger, surprise or fear tend to happen automatically, without much cognitive processing, the self-conscious emotions, including shame, guilt and pride, are more complex. They require self-reflection and self-evaluation.”
Essentially we’re comparing our behavior or situation to a social expectation. For instance, guilt comes when we reflect on the fact that we’ve violated a social rule. We need to be aware of the rule and what it means to break it. So, can dogs feel guilt? Well, exactly how self-reflective and self-evaluative are dogs?
Among humans, children begin to experience empathy and what are called secondary emotions when they are around 2 years old. Researchers estimate that the mental ability of a dog is roughly equal to that of an 18-month-old human. “This conclusion holds for most mental abilities as well as emotions,” says Stanley Coren in an article in Modern Dog Magazine. “Thus, we can look to the human research to see what we might expect of our dogs. Just like a two-year-old child, our dogs clearly have emotions, but many fewer kinds of emotions than found in adult humans.”
In other words, if 18-month-old children can’t yet experience these emotions, and dogs are roughly equal to them in cognitive and emotional ability, then dogs can’t feel these self-reflective emotions either. At least, that’s what researchers have concluded so far.
Is that guilt or fear?
This little puppy might feel guilty for chewing on clothes, or he could just be worried about getting in trouble. The two aren’t the same emotion. (Photo: InBetweentheBlinks/Shutterstock)
The evidence for primary emotions like love and happiness in dogs abounds, but empirical evidence for secondary emotions like jealousy and guilt is sparse. And this is partially because it’s difficult to create tests that provide clear-cut answers. When it comes to guilt, does a dog act guilty because she knows she did something wrong, or because she’s expecting a scolding? The same expression can come across as guilt or fear. How do we know which it is?
“In wolves, it is thought that guilt-related behaviors serve to reinforce social bonds, as in primates, by reducing conflict and eliciting tolerance from other members of the social group. The same could be true of dogs, though their social groups would primarily include humans. The problem is that the display of the associated behaviors of guilt are not, themselves, evidence of the capacity to emotionally experience guilt… It may still be some time before we can know for certain whether dogs can experience guilt, or whether people can determine if a dog has violated a rule prior to finding concrete evidence of it.”
Guilt, and other secondary emotions, are complicated. That’s exactly why cognitive awareness and emotional capacity in dogs is still a topic under study. In fact, it’s an area that has grown significantly in recent years. We may discover that dogs have a more complex range of emotions than we’re aware of today.
Dogs are highly social animals, and social animals are required to navigate a range of emotions in themselves and those around them to maintain social bonds. It wasn’t so long ago that scientists thought that dogs (and other non-human animals) didn’t have any feelings at all. Perhaps our understanding of dog emotions is simply limited by the types of tests we’ve devised to understand their emotions. After all, we’re trying to detect a sophisticated emotional state in a species that doesn’t speak the same language.
There’s a lot we don’t know
Dogs experience a range of emotions, but researchers are still trying to figure out exactly what those emotions are. (Photo: Hysteria/Shutterstock)
Marc Bekoff makes the argument for leaving the possibility open. In an article in Psychology Today he writes, “[B]ecause it’s been claimed that other mammals with whom dogs share the same neural bases for emotions do experience guilt, pride, and shame and other complex emotions, there’s no reason why dogs cannot.”
Keeping the possibility open is more than just an emotional animal rights issue. There is a scientific basis for continuing the research. A recent study showed that the brains of dogs and humans function in a more similar way than we previously thought.
Scientific American reports that “dog brains have voice-sensitive regions and that these neurological areas resemble those of humans. Sharing similar locations in both species, they process voices and emotions of other individuals similarly. Both groups respond with greater neural activity when they listen to voices reflecting positive emotions such as laughing than to negative sounds that include crying or whining. Dogs and people, however, respond more strongly to the sounds made by their own species.”
Until recently, we had no idea of the similar ways human and dog brains process social information.
So do dogs feel shame, guilt and pride? Maybe. Possibly. It’s still controversial, but for now, there seems to be no harm in assuming they do unless proven otherwise.

Footnote: At this point in the MNN article there was a link to a series of gorgeous photographs of dogs. If you dear readers can wait, then I will publish them this coming Sunday. If you can’t wait, then go here!
It really is about good people refusing to let evil dominate our world.
The response to yesterday’s post was incredible and very gratifying.
For I was conscious that many would simply reject the proposition that I saw in John Zande’s book, namely that, “there was an evil origin to the universe and, more directly, that the deep, and growing, suffering of the pinnacle of evolution, us humans, can be traced back to that evil origin.”
The emotional challenge, of which I am acutely aware, is recognising that core proposition, that as we humans evolve so too does the capacity for human suffering, yet not wanting to give up on my personal core belief that better times ahead are possible, given sufficient people sharing that power of hope. Echoing what Sue wrote as a response to yesterday’s post that motivated me to reply, in part, thus:
If there was one sentence of yours that struck me as spot on, it was your declaration that what we think is what we create. Or as I often reflect, we are what we think.
Jean and I last night watched the latest BBC Panorama report about the migrant/refugee crisis in Europe. It was profoundly upsetting for reasons that many will understand.
George Monbiot’s essay that follows shortly is also profoundly upsetting.
But if hope is to be translated into a determination to make a difference, then it demands that we don’t ignore the pain but use our anger to fuel our passion to behave appropriately: We are what we think! Or in the much more eloquent words of Albert Einstein:
Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.
George Monbiot is to be saluted for his commitment to questioning and I am privileged to have his permission to republish the following.
There may be water on Mars. But is there intelligent life on Earth?
By George Monbiot, published in the Guardian 30th September 2015
Evidence for flowing water on Mars – this opens up the possibility of life; of wonders we cannot begin to imagine. Its discovery is an astonishing achievement. Meanwhile, Martian scientists continue their search for intelligent life on Earth.
We might be captivated by the thought of organisms on another planet, but we seem to have lost interest in our own. The Oxford Junior Dictionary has been excising the waymarks of the living world. Adders, blackberries, bluebells, conkers, holly, magpies, minnows, otters, primroses, thrushes, weasels and wrens are now surplus to requirements.
In the past four decades, the world has lost 50% of its vertebrate wildlife. But across the latter half of this period, there has been a steep decline in coverage. In 2014, according to a study at Cardiff University, there were as many news stories broadcast by the BBC and ITV about Madeline McCann (who went missing in 2007) as there were about the entire range of environmental issues.
Think of what would change if we valued terrestrial water as much as we value the possibility of water on Mars. Only three percent of the water on this planet is fresh, and of that two-thirds is frozen. Yet we lay waste to the accessible portion. Sixty percent of the water used in farming is needlessly piddled away by careless irrigation. Rivers, lakes and aquifers are sucked dry, while what remains is often so contaminated that it threatens the lives of those who drink it. In the UK, domestic demand is such that the upper reaches of many rivers disappear during the summer. Yet still we install clunky old toilets and showers that gush like waterfalls.
As for salty water of the kind that enthralls us when apparently detected on Mars, on Earth we express our appreciation with a frenzy of destruction. A new report suggests that fish numbers have halved since 1970. Pacific bluefin tuna, that once roamed the seas in untold millions, have been reduced to an estimated 40,000, yet still they are pursued. Coral reefs are under such pressure that most could be gone by 2050. And in our own deep space, our desire for exotic fish rips through a world scarcely better known to us than the red planet’s surface. Trawlers are now working at depths of 2000 metres. We can only guess at what they might be destroying.
A few hours before the Martian discovery was announced, Shell terminated its Arctic oil prospecting in the Chukchi Sea. For the company’s shareholders, it’s a minor disaster: the loss of $4 billion. For those who love the planet and the life it sustains, it is a stroke of great fortune: it happened only because the company failed to find sufficient reserves. Had Shell succeeded, it would have exposed one of the most vulnerable places on Earth to spills that are almost inevitable, where containment is almost impossible. Are we to leave such matters to chance?
At the beginning of September, two weeks after he granted Shell permission to drill in the Chukchi Sea, Barack Obama travelled to Alaska to warn Americans about the devastating effects that climate change, caused by the burning of fossil fuels, might catalyse in the Arctic. “It’s not enough just to talk the talk”, he told them. “We’ve got to walk the walk.” We should “embrace the human ingenuity that can do something about it.” Human ingenuity is on abundant display at Nasa, which released those astounding images. But when it comes to policy, the search for intelligent life goes on.
Let the market decide: this is the way in which governments seek to resolve planetary destruction. Leave it to the conscience of consumers, while that conscience is muted and confused by advertising and corporate lies. In a near-vacuum of information, we are each left to decide what we should take from other species and other people; what we should allocate to ourselves or leave to succeeding generations. Surely there are some resources and some places – such as the Arctic and the deep sea – whose exploitation should simply stop?
All this drilling and digging and trawling and dumping and poisoning – what is it for anyway? Does it enrich human experience, or stifle it? A couple of weeks ago, I launched the hashtag #extremecivilisation, and invited suggestions. They have flooded in. Here are just a few of the products my correspondents have found. All of them, as far as I can tell, are real.
An egg tray for your fridge, that syncs with your phone to let you know how many eggs are left. A gadget for scrambling them – inside the shell. Wigs for babies, to allow “baby girls with little or no hair at all the opportunity to have a beautifully realistic hair style”. The iPotty, that permits toddlers to keep playing on their iPads while toilet training. A £2000 spider-proof shed. A snow sauna, on sale in the United Arab Emirates, in which you can create a winter wonderland with the flick of a switch. A refrigerated watermelon case on wheels: indispensable for picnics. Or perhaps not, as it weighs more than the melon. Anal bleaching cream, for … to be honest, I don’t want to know. An “automatic watch rotator” that saves you the bother of winding your luxury wrist candy. A smart phone for dogs, with which they can take pictures of themselves. Pre-peeled bananas, in polystyrene trays covered in clingfilm. Just peel back the packaging …
Every year, clever new ways of wasting stuff are devised, and every year we become more inured to the pointless consumption of the world’s precious resources. With each subtle intensification, the baseline of normality shifts. It should not be surprising to discover that the richer a country becomes, the less its people care about their impacts on the living planet.
Our alienation from the world of wonders with which we evolved has only intensified since David Bowie described a girl stumbling through a “sunken dream”, on her way to be “hooked to the silver screen”, where a long series of distractions diverts her from life’s great questions. The song, of course, was Life on Mars.
The interconnectedness of everything – even beyond our wildest imagination.
A while ago John Zande signed up to follow Learning from Dogs. Naturally, I went across to John’s blog to thank him. There I discovered that John is an animal lover and an author. For he states, referring to his book, that, “BUY IT. ALL PROCEEDS GO TO ANIMAL RESCUE AND SHELTER IN BRAZIL”. Fabulous!
(I did buy the book, am about 20% through it and finding it very stimulating, – if you would like to buy it then click the image of the book on John’s home page.)
Anyway, a few days later we watched the BBC Horizon programme on multiple universes. Here’s how the BBC introduced the programme:
Which Universe Are We In?
Horizon, 2014-2015 Episode 17 of 19
Imagine a world where dinosaurs still walk the earth. A world where the Germans won World War II and you are president of the United States. Imagine a world where the laws of physics no longer apply and where infinite copies of you are playing out every storyline of your life.
It sounds like a plot stolen straight from Hollywood, but far from it. This is the multiverse.
Until very recently the whole idea of the multiverse was dismissed as a fantasy, but now this strangest of ideas is at the cutting edge of science.
And for a growing number of scientists, the multiverse is the only way we will ever truly make sense of the world we are in.
Horizon asks the question: Do multiple universes exist? And if so, which one are we actually in?
Horizon is always great to watch but this episode was incredibly stimulating and interesting. Later, in a exchange of comments to one of John’s posts, where I referred to that programme, John wrote:
The mulitverse is actually the more reasonable explanation for why there is something, and although I don’t understand the maths, the people who do say its simplistically beautiful. Matt Rave is an associate professor of physics and comments here regularly. He has a great book on it all, Why is There Anything?
That lead me to purchasing Matthew Rave’s book that, likewise, is a most fascinating and unusual approach to this topic. His Amazon author’s page reveals that, “Dr. Matthew Rave is an assistant professor of physics at Western Carolina University, in the mountains of North Carolina. His research interests include interpretations of quantum mechanics, the geometric phase, solid state physics, and physics education.” Matthew Rave’s blogsite is here.
Matthew Rave’s book further illustrates the paradox, to my mind, that comes from thinking about why are we here, are we here and, if so, how do we know we are here?
So if that isn’t enough for you and me, then very recently The Conversation blogsite published the following from Geraint Lewis who is Professor of Astrophysics at the University of Sydney. It is republished here within the terms of The Conversation. Did I mention paradoxes and headaches!
To a human, the universe might seem like a very inhospitable place. In the vacuum of space, you would rapidly suffocate, while on the surface of a star you would be burnt to a crisp. As far as we know, all life is confined to a sliver of an atmosphere surrounding the rocky planet we inhabit.
But while the origin of life on Earth remains mysterious, there are bigger questions to answer. Namely: why do the laws of physics permit any life at all?
Hang on, the laws of physics? Surely they are a universal given and life just gets on with it?
But remember that the universe is built of fundamental pieces, particles and forces, which are the building blocks of everything we see around us. And we simply don’t know why these pieces have the properties they do.
There are many observational facts about our universe, such as electrons weighing almost nothing, while some of their quark cousins are thousands of times more massive. And gravity being incredibly weak compared to the immense forces that hold atomic nuclei together.
Why is our universe built this way? We just don’t know.
But what if…?
This means we can ask “what if” questions. What if the electron was massive and quarks were fleeting? What if electromagnetism was stronger than the nuclear strong force? If so, what would that universe be like?
Let’s consider carbon, an element forged in the hearts of massive stars, and an element essential to life as we know it.
Initial calculations of such stellar furnaces showed that they were apparently inefficient in making carbon. Then the British astronomer Fred Hoyle realised the carbon nucleus possesses a special property, a resonance, that enhanced the efficiency.
But if the strength of the strong nuclear force was only fractionally different, it would wipe out this property and leave the universe relatively devoid of carbon – and, thus, life.
The story doesn’t end there. Once carbon is made, it is ripe to be transmuted into heavier elements, particularly oxygen. It turns out that oxygen, due to the strength of the strong nuclear force, lacks the particular resonance properties that enhanced the efficiency of carbon creation.
This prevents all of the carbon being quickly consumed. The specific strength of the strong force has thus resulted in a universe with an almost equal mix of carbon and oxygen, a bonus for life on Earth.
Death of a universe
This is but a single example. We can play “what if” games with the properties of all of the fundamental bits of the universe. With each change we can ask, “What would the universe be like?”
The answers are quite stark. Straying just a little from the convivial conditions that we experience in our universe typically leads to a sterile cosmos.
This might be a bland universe, without the complexity required to store and process the information central to life. Or a universe that expands too quickly for matter to condense into stars, galaxies and planets. Or one that completely re-collapses again in a matter of moments after being born. Any complex life would be impossible!
The questions do not end there. In our universe, we live with the comfort of a certain mix of space and time, and a seemingly understandable mathematical framework that underpins science as we know it. Why is the universe so predictable and understandable? Would we be able to ask such a question if it wasn’t?
Our universe appears to balance on a knife-edge of stability. But why?

One of a multiverse
To some, science will simply fix it all. Perhaps, if we discover the “Theory of Everything”, uniting quantum mechanics with Einstein’s relativity, all of the relative masses and strengths of the fundamental pieces will be absolutely defined, with no mysteries remaining. To others, this is little more than wishful thinking.
Some seek solace in a creator, an omnipotent being that finely-tuned the properties of the universe to allow us to be here. But the move from the scientific into the supernatural leaves many uncomfortable.
There is, however, another possible solution, one guided by the murky and confused musings at the edge of science. Super-strings or M-theory (or whatever these will evolve into) suggest that the fundamental properties of the universe are not unique, but are somehow chosen by some cosmic roll of the dice when it was born.
This gives us a possible explanation of the seemingly special properties of the universe in which we live.
We are not the only universe, but just one in a semi-infinite sea of universes, each with their own peculiar set of physical properties, laws and particles, lifetimes and ultimately mathematical frameworks. As we have seen, the vast majority of these other universes in the overall multiverse are dead and sterile.
They only way we can exist to ask the question “why are we here?” is that we happen to find ourselves in a universe conducive to our very existence. In any other universe, we simply wouldn’t be around to wonder why we didn’t exist.
If the multiverse picture is correct, we have to accept that the fundamental properties of the universe were ultimately dished out in a game of cosmic roulette, a spin of the wheel that we appear to have won.
A very interesting report that recently appeared on Mother Nature Network (MNN).
We live in Josephine County here in Southern Oregon. Our next door neighbours to the East are Jackson County. Josephine and Jackson Counties share one very noble attribute: each is only one of just nine GMO-free counties in the entire United States of America. Plus, as evidenced at our local Grants Pass Farmers’ Market every Saturday, the growing of organic fruit and vegetables is widespread in our county. We feel very happy to have ended up in this part of America.
All of which makes a logical introduction to a report that appeared on MNN on September, 1st. It is republished below.

For safer, cheaper pest control, just add ants
Ants offer a surprisingly effective alternative to synthetic pesticides on crops ranging from cashews to sugar cane, according to a new review of more than 70 scientific studies.

Sometimes ants are pests, marching through our kitchens on an industrious quest for crumbs. But when faced with more serious pests — namely those that destroy crops on which people’s livelihoods depend — we can also use ants to our advantage.
Published in the Journal of Applied Ecology, a new research review suggests ants can control agricultural pests as efficiently as synthetic pesticides, with the bonus of being more cost-effective and generally safer. And since many pesticides pose a danger to helpful wildlife like birds, bees and spiders — not to mention humans — ants might be a key ally in feeding the planet’s booming human population.
The review covers more than 70 scientific studies on dozens of pest species that plague nine crop varieties in Africa, Southeast Asia and Australia. Because ants are organized as “superorganisms” — meaning the colony itself is like an organism, with individual ants acting as “cells” that can move around independently — they are uniquely capable of hunting down pests and then overwhelming them.
“Ants are great hunters and they work cooperatively,” says author Joachim Offenberg, a biologist at Aarhus University in Denmark, in a press release about the research. “When an ant finds its prey, it uses pheromones to summon help from other ants in the nest. By working together, they can subdue even large pests.”
Most studies in the review focused on weaver ants, a tropical genus of tree-dwelling ants that weave ball-shaped nests using leaves and larval silk. Since they live in the canopy of their host trees, near the fruit and flowers that need protection, weaver ants have a natural tendency to control pest populations in orchards.

In one three-year study, Australian cashew growers recorded yields 49 percent higher in trees guarded by weaver ants versus trees treated with synthetic chemicals. But higher yields were only part of the prize: The farmers also got higher-quality cashews from the trees with ants, resulting in a 71 percent higher net income.
Similar results were reported in mango orchards. While mango trees with ants had roughly the same yields as those with synthetic chemicals, the ants were cheaper — and the trees they inhabited grew higher-quality fruit. That led to a 73 percent higher net income compared with pesticide-treated trees. Not all crops had such dramatic results, but studies on more than 50 pests showed that ants can protect crops including cocoa, citrus and palm oil at least as effectively as pesticides.
“Although these are rare cases where the ants were superior to chemicals, many studies show that ants are just as efficient as chemical controls,” Offenberg says. “And of course ant technology is much cheaper than chemical pest control.”
To recruit weaver ants in their orchards, farmers just collect nests from the wild, hang them in plastic bags from tree branches and feed them a sugar solution while they build new nests. Once the ants establish their colony, farmers can help them expand by connecting target trees with aerial walkways made from string or vines.
The ants are mostly self-sufficient from there, needing only some water during the dry season — provided via plastic bottles in the trees — and pruning of non-target trees that host different ant colonies to prevent fights. Farmers can also help their ants by avoiding broad-spectrum insecticide sprays, researchers say.

It’s worth noting that ants can also be detrimental to some plants, such as when they herd sap-feeding insects like aphids and leafhoppers. But if they still fend off fruit-ruining flies and beetles, their net impact may be positive nonetheless. Not only do weaver ants kill pest insects on their trees, but their presence alone is reportedly enough to scare away marauders as large as snakes and fruit bats. And research suggests their urine even contains important plant nutrients.
The use of ants for pest control isn’t new. As early as 300 B.C., Chinese farmers could buy weaver ants in markets to release in their citrus groves, a practice that has faded over time, especially after the advent of chemical pesticides. But it may be coming back, both because ants are cheaper than pesticides and because certified organic produce can fetch higher prices, due to concerns that broad-spectrum pesticides harm more than just pests. Aarhus University is studying the use of weaver ants as pest control in Benin and Tanzania, for example, where the insects could lead to increased export revenue of $120 million and $65 million, respectively.
“To kill the flies with pesticides, you have to make the mango so poisonous that it can kill the maggot,” Aarhus University biologist Mogens Gissel Nielsen told China’s Xinhua news agency in 2010. “But when it is too poisoned for the maggot to eat, it might not be good for us to eat either.”
While the research in Offenberg’s review focused largely on weaver ants, he points out they “share beneficial traits with almost 13,000 other ant species, and are unlikely to be unique in their properties as control agents.” Lots of ants nest in the ground, and while it may be a challenge to relocate them, they too have shown promise in protecting a variety of commercially important crops.
“Weaver ants need a canopy for their nests, so they are limited to plantations and forestry in the tropics,” Offenberg says. “But ground-living ants can be used in crops such as maize and sugar cane. European wood ants are renowned for controlling pests in forestry, and new projects are trying to use wood ants to control winter moths in apple orchards. Ants could even be used to fight plant pathogens because they produce antibiotics to combat diseases in their dense societies.”

As with many of the other fine articles that appear on Mother Nature Network, this report by Russell McLendon has many links to other information sources, too many for me to set up. So if this report ‘speaks’ to you and you want to look up the background information then please go here and read it over on MNN.
Say the word ‘dog’ to me and my immediate thought would be of the domesticated animal, as I’m sure would be the first thought of thousands of others.
But our wonderful doggie companions came from the wild and in some countries wild dogs still are widely found. There was an article on the Mokolodi Nature Reserve blogsite in November, 2009 specifically about wild dogs, that included the following picture:
Wild hunting dogs drinking.
All of which is a wonderful reminder that wilderness is a critical and essential element in the overall health of our planet, and by extension, of ourselves.
The academic blogsite The Conversation yesterday published an article by William Lynn who is a Research Scientist in Ethics and Public Policy at Clark University. It proposes a wonderful way of keeping our populations of wild animals healthy and vibrant through rewilding. It is republished here within the terms of The Conversation.

Setting aside half the Earth for ‘rewilding’: the ethical dimension
August 26, 2015 5.50am EDT

The famous biologist and naturalist would do this by establishing huge biodiversity parks to protect, restore and connect habitats at a continental scale. Local people would be integrated into these parks as environmental educators, managers and rangers – a model drawn from existing large-scale conservation projects such as Area de Conservación Guanacaste (ACG) in northwestern Costa Rica.
The backdrop for this discussion is that we are in the sixth great extinction event in earth’s history. More species are being lost today than at any time since the end of the dinosaurs. There is no mystery as to why this is happening: it is a direct result of human depredations, habitat destruction, overpopulation, resource depletion, urban sprawl and climate change.
Wilson is one of the world’s premier natural scientists – an expert on ants, the father of island biogeography, apostle of the notion that humans share a bond with other species (biophilia) and a herald about the danger posed by extinction. On these and other matters he is also an eloquent writer, having written numerous books on biodiversity, science, and society. So when Wilson started to talk about half-Earth several years ago, people started to listen.
As a scholar of ethics and public policy with an interest in animals and the environment, I have been following the discussion of half-Earth for some time. I like the idea and think it is feasible. Yet it suffers from a major blind spot: a human-centric view on the value of life. Wilson’s entry into this debate, and his seeming evolution on matters of ethics, is an invitation to explore how people ought to live with each other, other animals and the natural world, particularly if vast tracts are set aside for wildlife.
The ethics of Wilson’s volte-face
I heard Wilson speak for the first time in Washington, DC in the early 2000s. At that talk, Wilson was resigned to the inevitable loss of much of the world’s biodiversity. So he advocated a global biodiversity survey that would sample and store the world’s biotic heritage. In this way, we might still benefit from biodiversity’s genetic information in terms of biomedical research, and perhaps, someday, revive an extinct species or two.
Not a bad idea in and of itself. Still, it was a drearily fatalistic speech, and one entirely devoid of any sense of moral responsibility to the world of nonhuman animals and nature.
What is striking about Wilson’s argument for half-Earth is not the apparent about-face from cataloging biodiversity to restoring it. It is the moral dimension he attaches to it. In several interviews, he references the need for humanity to develop an ethic that cares about planetary life, and does not place the wants and needs of a single species (Homo sapiens sapiens) above the well-being of all other species.

To my ear, this sounds great, but I am not exactly sure how far it goes. In the past, Wilson’s discussions of conservation ethics appear to me clearly anthropocentric. They espouse the notion that we are exceptional creatures at the apex of evolution, the sole species that has intrinsic value in and of ourselves, and thus we are to be privileged above all other species.
In this view, we care about nature and biodiversity only because we care about ourselves. Nature is useful for us in the sense of resources and ecological services, but it has no value in and of itself. In ethics talk, people have intrinsic value while nature’s only value is what it can do for people – extrinsic value.
For example, in his 1993 book The Biophilia Hypothesis, Wilson argues for “the necessity of a robust and richly textured anthropocentric ethics apart from the issues of rights [for other animals or ecosystems] – one based on the hereditary needs of our own species. In addition to the well-documented utilitarian potential of wild species, the diversity of life has immense aesthetic and spiritual value.”
The passage indicates Wilson’s long-held view that biodiversity is important because of what it does for humanity, including the resources, beauty and spirituality people find in nature. It sidesteps questions of whether animals and the rest of nature have intrinsic value apart from human use.
His evolving position, as reflected in the half-Earth proposal, seems much more in tune with what ethicist call non-anthropocentrism – that humanity is simply one marvelous but no more special outcome of evolution; that other beings, species and/or ecosystems also have intrinsic value; and that there is no reason to automatically privilege us over the rest of life.
What kind of a species are we that we treat the rest of life so cheaply? There are those who think that’s the destiny of Earth: we arrived, we’re humanizing the Earth, and it will be the destiny of Earth for us to wipe humans out and most of the rest of biodiversity. But I think the great majority of thoughtful people consider that a morally wrong position to take, and a very dangerous one.
The non-anthropocentric view does not deny that biodiversity and nature provide material, aesthetic and spiritual “resources.” Rather, it holds there is something more – that the community of life has value independent of the resources it provides humanity. Non-anthropocentric ethics requires, therefore, a more caring approach to people’s impact on the planet. Whether Wilson is really leaving anthropocentrism behind, time will tell. But for my part, I at least welcome his opening up possibilities to discuss less prejudicial views of animals and the rest of nature.
The 50% solution
It is interesting to note that half-Earth is not a new idea. In North America, the half-Earth concept first arose in the 1990s as a discussion about wilderness in the deep ecology movement. Various nonprofits that arose out of that movement continued to develop the idea, in particular the Wildlands Network, the Rewilding Institute and the Wild Foundation.
These organizations use a mix of conservation science, education and public policy initiatives to promote protecting and restoring continental-scale habitats and corridors, all with an eye to preserving the native flora and fauna of North America. One example is ongoing work to connect the Yellowstone to Yukon ecosystems along the spine of the Rocky Mountains.
Take it up a notch? The British Columbia Ministry of Transportation recently started to add signs warning motorists when they are likely to encounter wildlife. British Columbia Ministry of Transportation, CC BY-NC-ND
When I was a graduate student, the term half-Earth had not yet been used, but the idea was in the air. My classmates and I referred to it as the “50% solution.” We chose this term because of the work of Reed Noss and Allen Cooperrider’s 1994 book, Savings Nature’s Legacy. Amongst other things, the book documents that, depending on the species and ecosystems in question, approximately 30% to 70% of the original habitats of the Earth would be necessary to sustain our planet’s biodiversity. So splitting the difference, we discussed the 50% solution to describe this need.
This leads directly into my third point. The engagement of Wilson and others with the idea of half-Earth and rewilding presupposes but does not fully articulate the need for an urban vision, one where cities are ecological, sustainable and resilient. Indeed, Wilson has yet to spell out what we do with the people and infrastructure that are not devoted to maintaining and teaching about his proposed biodiversity parks. This is not a criticism, but an urgent question for ongoing and creative thinking.
Humans are urbanizing like never before. Today, the majority of people live in cities, and by the end of the 21st century, over 90% of people will live in a metropolitan area. If we are to meet the compelling needs of human beings, we have to remake cities into sustainable and resilient “humanitats” that produce a good life.
Such a good life is not to be measured in simple gross domestic product or consumption, but rather in well-being – freedom, true equality, housing, health, education, recreation, meaningful work, community, sustainable energy, urban farming, green infrastructure, open space in the form of parks and refuges, contact with companion and wild animals, and a culture that values and respects the natural world.
To do all this in the context of saving half the Earth for its own sake is a tall order. Yet it is a challenge that we are up to if we have the will and ethical vision to value and coexist in a more-than-human world.

I am sure many will agree that this is a very interesting idea and one that I hope is eventually adopted. For the sake of all our wild animals, including our dogs.
This is a TED video presented by Will Marshall. A quick web search reveals that Will Marshall is:
Co-founder & CEO of Planet Labs.
Planet Labs is helping share near-real-time images of our planet, from a constellation of earth-observing satellites.
In his Twitter bio, William Marshall calls himself a “quantum physicist cum space scientist in search of world peace and harmony.” And when you hear about his job, it falls into place: he and his cofounders at Planet Labs want to show the earth what it looks like, almost real time, via a new network of compact, capable satellites. They hope that up-to-date images will inform future humanitarian and commercial projects all over our planet; it will enable people to make decisions that enable us to take care of our dearest spaceship, spaceship earth.
Before co-founding Planet Labs, Marshall was a scientist at NASA/USRA, where he helped to formulate the Small Spacecraft Office at NASA Ames Research Center. He worked on lunar orbiter mission LADEE, lunar impactor mission LCROSS and the groundbreaking PhoneSat project, building satellites out of consumer parts.
It was only a couple of mouse clicks to find the website for Planet Labs.
All of which is my way of introducing the TED video but not before thanking next door neighbour Larry Little who emailed me the link to the video.

But Planet Labs’ Will Marshall says we can do better and go faster — by getting smaller. He introduces his tiny satellites — no bigger than 10 by 10 by 30 centimeters — that, when launched in a cluster, provide high-res images of the entire planet, updated daily.

STUDY REVEALS SCIENTIFIC REASON YOUR DOG IS HAPPY TO SEE YOU
A new study explains why your dog gets so happy to see you. (Shutterstock)
Tuesday, August 11, 2015 11:04AM
Is your dog overwhelmed with joy anytime you walk through the door? There’s a scientific reason behind their excitement, a new study shows, and it’s not just because you feed them.
Researchers at Emory University used functional magnetic resonance imaging (fMRI) to scan dogs’ brains for activity when they were shown images of dog faces, human faces and ordinary objects.
The dogs’ temporal lobes lit up “significantly more” when presented with the faces than with the objects. These findings suggest that dogs may recognize both human and dog faces.
Facial recognition causes dog brains to activate in the same areas as in monkey and human brains, the study found. This is separate from the “reward areas” that would be triggered by anticipation of food.
“What we’re finding with the imaging work is that dogs love their humans-and not just for food,” researcher Gregory Berns told io9. “They love the company of humans simply for its own sake.”
“The existence of a face-selective region in the temporal dog cortex opens up a whole range of new questions to be answered about their social intelligence,” the researchers explained, such as whether dogs can understand different facial expressions and whether they can read body language.
This isn’t the first time scientists have explored what makes dogs’ tails wag with excitement when reunited with their owners. A January study that Berns was also involved in found that dogs have a positive reaction to the scent of familiar humans compared with other smells, even those of other dogs.
The results of that study “suggested that not only did the dogs discriminate that scent [of familiar humans] from the others, they had a positive association with it.”
A 2013 behavioral study found that dogs can show when they’re happy to see their owners by lifting their eyebrows. Their left eyebrow went up when they saw their respective owners, the study found. They didn’t have this reaction for other things that may excite them, such as attractive toys.
