Beyond our beautiful planet.

Lifting one’s eyes to the far heavens.

Yesterday, I reposted 12 stunning photographs of the world we live on that had been published on Mother Nature Network on the 19th.

Coincidentally, I also saw something on the 19th that was just as breathtaking as those pictures of Planet Earth.  Here’s the picture that took my breath away.

HERSCHEL’S VIEW OF THE HORSEHEAD NEBULA
HERSCHEL’S VIEW OF THE HORSEHEAD NEBULA

That image comes from the ESA Space in Images website, from which one learns:

  • Copyright: ESA/Herschel/PACS, SPIRE/N. Schneider, Ph. André, V. Könyves (CEA Saclay, France) for the “Gould Belt survey” Key Programme
  • Description: Stunning new view from ESA’s Herschel space observatory of the iconic Horsehead Nebula in the context of its surroundings. The image is a composite of the wavelengths of 70 microns (blue), 160 microns (green) and 250 microns (red), and covers 4.5×1.5 degrees. The image is oriented with northeast towards the left of the image and southwest towards the right.The Horsehead Nebula resides in the constellation Orion, about 1300 light-years away, and is part of the vast Orion Molecular Cloud complex. The Horsehead appears to rise above the surrounding gas and dust in the far right-hand side of this scene, and points towards the bright Flame Nebula. Intense radiation streaming away from newborn stars heats up the surrounding dust and gas, making it shine brightly to Herschel’s infrared-sensitive eyes (shown in pink and white in this image).To the left, the panoramic view also covers two other prominent sites where massive stars are forming, NGC 2068 and NGC 2071.

    Extensive networks of cool gas and dust weave throughout the scene in the form of red and yellow filaments, some of which may host newly forming low-mass stars.

Don’t know about you but I found that description a little dry, so to speak.

The BBC had a much friendlier version:

By Jonathan Amos, Science correspondent, BBC News.

Europe’s Herschel space telescope has imaged one of the most popular subjects in the sky – the Horsehead Nebula – and its environs.

The distinctively shaped molecular gas cloud is sited some 1,300 light-years from Earth in the Constellation Orion.

It is in a region of space undergoing active star formation – something Herschel has been most keen to study.

The Hubble space observatory has also returned to the Horsehead scene, to celebrate 23 years in orbit.

Together, these two great facilities give scientists a much broader insight into what is taking place in this familiar patch of the heavens.

“You need images at all scales and at all wavelengths in astronomy in order to understand the big picture and the small detail,” said Prof Matt Griffin, the principal investigator on Herschel’s SPIRE instrument.

“In this new Herschel view, the Horsehead looks like a little feature – a pimple. In reality, of course, it is a very large entity in its own right, but in this great sweep of a picture from Herschel you can see that the nebula is set within an even larger, molecular-cloud complex where there is a huge amount of material and a great range of conditions,” the Cardiff University, UK, researcher told BBC News.

To provide a sense of scale, the Horsehead Nebula, also known in the catalogues as “Barnard 33”, is about five light-years “tall”.

Hubble sees the Horsehead in near-infrared light. Herschel, on the other hand, goes to much longer wavelengths. This allows it to see the glow coming directly from cold gas and dust – the material that will eventually collapse under gravity to form the next generation of stars.

Scientists are particularly keen to understand the mechanisms that drive the production of the biggest stars – objects much more massive than our own Sun that form relatively fast, burn bright but brief lives, and interact strongly with their environment, influencing the next round of star formation.

Anyway, that’s more than enough to copy directly from that BBC article.  Read the rest by going here.  All I will add is Jonathan’s last sentence, “A scholarly paper describing Herschel’s investigation of the Orion Molecular Cloud Complex has been published in the journal Astrophysical Journal Letters.

Oh, and ponder on how far away from Earth is that Constellation Orion.  Remember it was stated as 1,300 light-years.

Well, one light-year is just under 10 million, million kilometres (or about 6 million, million miles).  Apparently defined by the  IAU, or to give its the full name, the International Astronomical Union, a light-year is the distance that light travels in a vacuum in one Julian year.

So brace yourself!  1,300 light-years is just under 13,000,000,000,000,000 kilometres or in old money, 7,800,000,000,000,000 miles.

Rather puts pottering to the shops in Grants Pass into perspective!

The healing power of dogs.

How dogs offer us humans health and happiness.

Many months ago, I was contacted by a Peter Bloch offering to write a guest post on the subject of the healing power of dogs.  Peter had read a post that I had published in July last year which prompted the email dialogue between us.

Not going to say much more at this stage except that today I am republishing that post from last July.  On Monday, I will introduce Peter and his guest post.  Then on Tuesday, I will speak of my own experiences both as entrepreneurial mentor and as a ‘customer’ of a wonderful psychotherapist back in Devon during 2007.  Hope that works for you.

So here’s that Learning from Dogs post.

000OOOooo

The bond between dogs and humans

Such a beautiful and mutually-important relationship.

I didn’t plan to write more about this subject thinking that my last two posts, Woof at the Door and Prof. Pat Shipman, more than covered the theme; indeed much more.

But then a flurry of other articles conspired to pass my desk.

In no particular order there was an article on the Big Think website, Do Dogs Speak Human?  As the article opened,

What’s the Big Idea?

Perhaps the better question is, do humans speak dog? Either way, the debate over whether language is unique to humans, or a faculty also possessed by wild and domestic animals from dogs to apes to dolphins, is an interesting one. The answer depends on exactly how we define “language,” and who’s doing the talking, says David Bellos, the Booker prize-winning translator.

The article includes this three-minute video,

and concludes,

Broadly, a language is a mode of expression. “The argument that only human language is language and that animal communication systems, however sophisticated they are — and some of them are quite sophisticated — are not languages because they consist of discrete signals is a circular argument,” he argues. “It’s a self-fulfilling thing. And I think we should be a little bit more interested in the complexity and the variability of animal communication systems and less rigid about this distinction between what is a language and what is not a language.”

For now, we’re happy with this:

The June 30th edition of The Economist had an article entitled, Can dogs really show empathy towards humans? (You may have to register (free) to view this.)  That report ends, as follows,

As they report in Animal Cognition, “person-oriented behaviour” did sometimes take place when either the stranger or the owner hummed, but it was more than twice as likely to occur if someone was crying. This indicated that dogs were differentiating between odd behaviour and crying. And of the 15 dogs in the experiment that showed person-oriented responses when the stranger cried, all of them directed their attention towards the stranger rather than their owner.

These discoveries suggest that dogs do have the ability to express empathetic concern. But although the results are clear enough, Dr Custance argues that more work needs to be done to be sure that such behaviour is true empathy. It is possible, she points out, that the dogs were drawing on previous experiences in which they were rewarded for approaching distressed human companions. Dog-owners, however, are unlikely to need any more convincing.

It was then an easy follow-up to that Animal Cognition article which is available online here; here’s the abstract,

Empathy covers a range of phenomena from cognitive empathy involving metarepresentation to emotional contagion stemming from automatically triggered reflexes.

An experimental protocol first used with human infants was adapted to investigate empathy in domestic dogs. Dogs oriented toward their owner or a stranger more often when the person was pretending to cry than when they were talking or humming. Observers, unaware of experimental hypotheses and the condition under which dogs were responding, more often categorized dogs’ approaches as submissive as opposed to alert, playful or calm during the crying condition. When the stranger pretended to cry, rather than approaching their usual source of comfort, their owner, dogs sniffed, nuzzled and licked the stranger instead.

The dogs’ pattern of response was behaviorally consistent with an expression of empathic concern, but is most parsimoniously interpreted as emotional contagion coupled with a previous learning history in which they have been rewarded for approaching distressed human companions.

It doesn’t get closer than this.

The evolution of dogs

Not quite as obvious as it might seem.

Considering that this blog is called Learning from Dogs, there has been precious little published about the animal species known as Canis familiaris; the classification of the domestic dog.  Let me try to correct that.

So, this reference explains:

The subdivision of Canidae into “foxes” and “true dogs” may not be in accordance with the actual relations; also, the taxonomic classification of several canines is disputed. Recent DNA analysis shows that Canini (dogs) and Vulpini (foxes) are valid clades (see phylogeny below). Molecular data imply a North American origin of living Canidae and an African origin of wolf-like canines (CanisCuon, and Lycaon).

Currently, the domestic dog is listed as a subspecies of Canis lupusC. l. familiaris, and the dingo (also considered a domestic dog) as C. l. dingo, provisionally a separate subspecies from C. l. familiaris; the red wolfeastern Canadian wolf, and Indian wolf are recognized as subspecies. Many sources list the domestic dog as Canis familiaris, but others, including the Smithsonian Institution and the American Society of Mammalogists, more precisely list it as a subspecies of C. l. familiaris; the red wolf, eastern Canadian wolf, and Indian wolf may or may not be separate species; in the past, the dingo has been variously classified as Canis dingoCanis familiaris dingo and Canis lupus familiaris dingo.

However a recent paper published by Nature magazine throws some interesting light of the development on the domestic dog.  As the article preview explains:

The genomic signature of dog domestication reveals adaptation to a starch-rich diet

The domestication of dogs was an important episode in the development of human civilization. The precise timing and location of this event is debated and little is known about the genetic changes that accompanied the transformation of ancient wolves into domestic dogs. Here we conduct whole-genome resequencing of dogs and wolves to identify 3.8 million genetic variants used to identify 36 genomic regions that probably represent targets for selection during dog domestication.

Nineteen of these regions contain genes important in brain function, eight of which belong to nervous system development pathways and potentially underlie behavioural changes central to dog domestication. Ten genes with key roles in starch digestion and fat metabolism also show signals of selection. We identify candidate mutations in key genes and provide functional support for an increased starch digestion in dogs relative to wolves. Our results indicate that novel adaptations allowing the early ancestors of modern dogs to thrive on a diet rich in starch, relative to the carnivorous diet of wolves, constituted a crucial step in the early domestication of dogs.

The BBC News website picked up on this:

Dog evolved ‘on the waste dump’

Jonathan AmosBy Jonathan Amos Science correspondent, BBC News

Anyone who owns a dog knows that it will rummage around in the kitchen bin looking for food, given half a chance.

But this annoying behaviour may have a more profound undercurrent than we realise, according to scientists.

A new study of dog genetics reveals numerous genes involved in starch metabolism, compared with wolves.

It backs an idea that some dogs emerged from wolves that were able to scavenge and digest the food waste of early farmers, the team tells Nature journal.

No-one knows precisely when or how our ancestors became so intimately connected with dogs, but the archaeological evidence indicates it was many thousands of years ago.

One suggestion is that the modern mutt emerged from ancient hunter-gatherers’ use of wolves as hunting companions or guards.

But another opinion holds that domestication started with wolves that stole our food leftovers and eventually came to live permanently around humans as a result.

Anyone who owns or loves dogs will find this article fascinating.  Jonathan Amos goes on to say:

“This second hypothesis says that when we settled down, and in conjunction with the development of agriculture, we produced waste dumps around our settlements; and suddenly there was this new food resource, a new niche, for wolves to make use of, and the wolf that was best able to make use of it became the ancestor of the dog,” explained Erik Axelsson from Uppsala University.

“So, we think our findings fit well with this theory that the dog evolved on the waste dump,” he told BBC News.

Dr Axelsson and colleagues examined the DNA of more than 50 modern dogs from breeds as diverse as the cocker spaniel and the German shepherd. They then compared their generic genetic information with those of 12 wolves taken from across the world.

The Swedish-US team scanned the DNA sequences of the two types of canid for regions of major difference. These would be locations likely to contain genes important in the rise of the domesticated dog.

Axelsson’s group identified 36 such regions, carrying a little over a hundred genes. The analysis detected the presence of two major functional categories – genes involved in brain development and starch metabolism.

In the case of the latter, it seems dogs have many more genes that encode the enzymes needed to break down starch, something that would have been advantageous in an ancestor scavenging on the discarded wheat and other crop products of early farmers.

Do go across to that BBC item and read the rest of the article.

That article and the paper in Nature magazine resonate strongly with an article written on the Dr George Johnson on Science website.  In fact I referred to the George Johnson piece when I first published the Dogs and integrity side piece in July 2009. (My how time flies!)  As that George Johnson piece reveals:

This week I found myself wondering about Boswell’s origins. From what creature did the domestic dog arise? Darwin suggested that wolves, coyotes, and jackals — all of which can interbreed and produce fertile offspring– may all have played a role, producing a complex dog ancestry that would be impossible to unravel. In the 1950s, Nobel Prize-winning behaviorist Konrad Lorenz suggested some dog breeds derive from jackals, others from wolves.

Based on anatomy, most biologists have put their money on the wolf, but until recently there was little hard evidence, and, as you might expect if you know scientists, lots of opinions.

The issue was finally settled in 1997 by an international team of scientists led by Robert Wayne of the University of California, Los Angeles. To sort out the evolutionary origin of the family dog, Wayne and his colleagues used the techniques of molecular biology to compare the genes of dogs with those of wolves, coyotes and jackals.

Wayne’s team collected blood, tissue, or hair from 140 dogs of sixty-seven breeds, and 162 wolves from North America, Europe, Asia, and Arabia. From each sample they extracted DNA from the tiny organelles within cells called mitochondria.

While the chromosome DNA of an animal cell derives from both parents, the mitochondrial DNA comes entirely from the mother. Biologists love to study mitochondrial DNA because of this simple line of descent, female-to-female-to-female. As changes called mutations occur due to copying mistakes or DNA damage, the mitochondrial DNA of two diverging lines becomes more and more different. Ancestors can be clearly identified when you are studying mitochondrial DNA, because clusters of mutations are not shuffled into new combinations like the genes on chromosomes are. They remain together as a particular sequence, a signature of that line of descent.

Finally, just watch this short trailer for a BBC Horizon screened in early 2010.  (Wet eyes warning!)

So the next time you look a dog in the eyes or hug their lovely furry body, think how far back the relationship goes and marvel at how much we have learnt from them.

Man and dog.  Each loving and protecting the other!

Future uncertainties!

Prediction is very difficult, especially if it’s about the future. Niels Bohr

I love this saying from Mr. Bohr and often repeat it, albeit at times with my own twist to it.  I was reminded of this uncertainty of the future from some comments to a recent post over at Lack of Environment.  The particular post was called Can technology save us? and was a reflection of Martin Lack, the blog’s author, watching a recent BBC Horizon special called Tomorrow’s World.  (There’s the YouTube of the broadcast at the end of this post.) Martin opened his post by saying:

I happened to stumble across a BBC TV Horizon special, entitled ‘Tomorrow’s World’ last Thursday.  It begins with a fascinating review of humankind’s history of – and propensity for – invention. It also explains some truly fascinating – and inspiring – developments in the spheres of space exploration, nanotechnology, biotechnology, and power generation.

In the introduction, the programme presenter and narrator Liz Bronnin explains how, after 100’s of thousands of years of technological stagnation, the fast-moving world of technological innovation is very definitely a modern invention.

Then a little later Martin goes on to say:

After about 32 minutes, Bronnin introduces the power of the Internet to promote innovation – crowd-sourcing research funding and the concept of open-source technology – the complete abrogation of intellectual copyright… It is a fundamental challenge to globalised Capitalism; but it may well be the solution to many of our problems…

However, to me, the final third of the programme is by far the most fascinating… It looks at the challenges of finding a replacement for fossil fuels. It provides a very clear message that this is a technological challenge driven by the reality of physics – not by ideology.

But, overall, Martin lets us know his perspective with his final paragraphs:

Re-engineering nature for our benefit will, without doubt, be very very useful. However, I still think the optimism of the comment at the very end of the programme “…I never worry about the future of the human race, because I think we are totally capable of solving problems…” is very unwise. This is because anthropogenic climate disruption is a problem that is getting harder to solve the longer we fail to address it effectively.

Bronnin concludes by saying that, “it is an exciting time to be alive…” However, I remain very nervous. This is because, as Professor Peter Styles of Keele University – a strong supporter of the hydraulic fracturing industry – recently acknowledged, it will be impossible for carbon capture and storage to remove enough CO2 from the atmosphere to prevent very significant changes to our climate. This is because of the collective hypnosis that deludes most people into seeing perpetual economic growth as the solution to all our problems.

In short, I am certain that technology alone cannot save us. In order to avoid the ecological catastrophe that all but the most ideologically-prejudiced and wilfully-blind can see developing all around us… we need to modify our behaviour: This primarily means that we need to acknowledge the injustice of a “use it up and wear it out” mentality and, as individuals, all learn to use an awful lot less energy.

Climate change “sceptics” have picked a fight with history and science – primarily with the concept of Entropy – and they will lose. The only question that remains is this: Are we going to let them put us all in (what xraymike79 recently called) ‘the dustbin of failed evolutionary experiments’.

Now Jean and I also watched the Horizon special and, to be perfectly frank, found it both uplifting and inspiring.  It seemed a great counter to the overwhelming volume of commentary these days along the lines of ‘The end of the world is nigh!‘ some of that coming from yours truly! That’s not to make light of the huge hurdles ahead.

But it was a couple of comments on Martin’s post from Patrice Ayme that got me thinking.  Here’s the exchange that went between Patrice and Martin following on from a comment from Thomas Foster.

Considering that it is technology which has enabled us to “conquer” nature and thus the degradation of the environment which is a consequence of that it seems most unlikely to this writer that the cause will also bring about a cure. Thomas Foster

—–

The genus Homo has been technological for 5 million years. Give or take two million. Homo is the cure for life. Patrice Ayme

—-

If we Homo Sapiens have been technological for 5 million years, we have spent most of that time being very unsuccessful; and have spent the rest being far too successful. Is there no scope for just living in harmony with our environment (as opposed to being at war with it)? Martin Lack

—-

Hominids have been masters of the environment for at least three million years. By a million years ago, only Homo was left (but for places like Flores). Dozens of megafauna species got annihilated. Homo’s technology has extended to the entire Earth for at least a million years. The Earth itself was turned into a tool. A tool we are not at war with, but that we use. Patrice Ayme

—-

A utilitarian attitude to Nature is one that does not recognise its inherent value (i.e. which it would have even if we did not exist). Seeing ourselves as superior to Nature rather than as part of it has resulted in our not living in harmony with it. This is, by definition, equivalent to being at war with Nature. QED. Refer: Nature is not your enemyMartin Lack

—-

Call it what you want, Martin. Man manipulates nature, and that nature one calls nature has not been “natural” for more than a million years. Except if one views man as part of nature! Patrice Ayme

Patrice is a very clear thinker even if, at times, pretty hard-hitting.  But this exchange confirmed in my mind that clearly looking out to the future must always be hard.  Most certainly in this period of mankind’s evolution predicting the future is especially difficult.  Hence my contribution to Martin’s post:

Jean and I watched the Horizon special a couple of evenings ago. To be honest, I’m not entirely sure what my overall thoughts are in response to your post, Martin. What does come to mind is that old saying, “Never underestimate the power of unintended consequences.

So it may be that we are at a particular point in time, or more likely an era, where seeing clearly into the future is challenging.

The one aspect of modern life that is a game-changer is what we are doing now. Sharing ideas and thoughts across a far-flung net. Not only as the Horizon programme illustrated but as ordinary people trying to make sense of the world.

These are incredibly uncertain times.  Undoubtedly not the first in man’s long history as an historian will explain (cue to Alex!).   But to all of us alive today, these are the most uncertain times we have ever experienced!

No wonder so many of us feel lost at times in today’s world.

Here’s that BBC Horizon, courtesy of YouTube.

I will close with this thought from one masterly ‘wordsmith’, William Wordsworth.

“Life is divided into three terms – that which was, which is, and which will be. Let us learn from the past to profit by the present, and from the present, to live better in the future.”

Meet Molly.

A most heart-warming story! Beats the heck out of murders, politics and terrorists!

This was sent in by John Hurlburt for Jean who has been a bit of a ‘horse lady’ in her times and is devoted to the two miniature horses we have here in Oregon.

oooOOOooo

Meet Molly

molly1

Molly is a gray speckled pony who was abandoned by her owners when Hurricane Katrina hit southern Louisiana . She spent weeks on her own before finally being rescued and taken to a farm where abandoned animals were stockpiled. While there, she was attacked by a dog and almost died.  Her gnawed right front leg became infected and her vet went to Louisiana State University (LSU) for help.

However, LSU were overwhelmed and Molly became a ‘welfare’ case. You know where that goes, don’t you!

Then surgeon Rustin Moore met Molly and changed his mind. He saw how Molly was careful to lie down on different sides so she didn’t seem to get sores.  He saw how Molly allowed people to handle her. She protected her injured leg. She constantly shifted her weight and didn’t overload her good leg. She was a smart pony with a serious survival ethic.

Surgeon Moore agreed to remove her leg below the knee and a temporary artificial limb was built. Molly walked out of the clinic and, in a very real sense, that’s where her story really begins.

This was the right horse and the right owner!” Moore insisted.

Molly happened to be a one-in-a-million patient. She’s tough as nails, but sweet, and she was willing to cope with pain. She made it obvious she understood that she was in trouble. The other important factor, according to Moore , is having a truly committed and compliant owner who is dedicated to providing the daily care required over the lifetime of the horse.

Molly’s story turns into a parable for life in Post-Katrina Louisiana.  The little pony gained weight and her mane finally felt a comb.  Then, amazingly, a prosthesis designer built her a leg.

The prosthetic has given Molly a whole new life, Allison Barca DVM, Molly’s regular vet, reports:

And she asks for it. She will put her little limb out and come to you and let you know that she wants you to put it on. Sometimes she wants you to take it off too. And sometimes, Molly gets away from Barca. “It can be pretty bad when you can’t catch a three-legged horse,” she laughs.

Most important of all, Molly has a job now. Kay, the rescue farm owner, started taking Molly to shelters, hospitals, nursing homes, and rehabilitation centers. Anywhere she thought that people needed hope. Wherever Molly went, she showed people her pluck. She inspired people, and she had a good time doing it.

It’s obvious to me that Molly had a bigger role to play in life,” Kay said. “She survived the hurricane, she survived a horrible injury, and now she is giving hope to others.

Allison Barca concluded, “She’s not back to normal, but she’s going to be better. To me, she could be a symbol for New Orleans itself.”

This is Molly's most recent prosthesis.
This is Molly’s most recent prosthesis.

Wherever Molly goes, she leaves a smiley hoof print behind.  Literally as well as metaphorically.

The photo shows the ground surface that she stands on has a smiley face embossed in it!
The photo shows that the bottom flat surface of the prosthesis has a smiley face embossed in it!

Leave you with that wonderful feeling of love for Molly?  Feel free to share it with all the animal lovers that you know.

What part of the argument are you missing?

Sometimes one just scratches the head and wonders!

In yesterday’s post, I wrote, “strongly resonated with a recent item on Peter Sinclair’s excellent blog Climate Denial Crock of the Week …”

Global Warming Continues to Accelerate

March 25, 2013

slide12

Skeptical Science:

A new study of ocean warming has just been published in Geophysical Research Letters by Balmaseda, Trenberth, and Källén (2013).  There are several important conclusions which can be drawn from this paper.

  • Completely contrary to the popular contrarian myth, global warming has accelerated, with more overall global warming in the past 15 years than the prior 15 years.  This is because about 90% of overall global warming goes into heating the oceans, and the oceans have been warming dramatically.
  • Some recent studies have concluded based on the slowed global surface warming over the past decade that the sensitivity of the climate to the increased greenhouse effect is somewhat lower than the IPCC best estimate.  Those studies are fundamentally flawed because they do not account for the warming of the deep oceans.
  • The slowed surface air warming over the past decade has lulled many people into a false and unwarranted sense of security.

The main results of the study are illustrated in its Figure 1.

Figure 1: Ocean Heat Content from 0 to 300 meters (grey), 700 m (blue), and total depth (violet) from ORAS4, as represented by its 5 ensemble members. The time series show monthly anomalies smoothed with a 12-month running mean, with respect to the 1958–1965 base period. Hatching extends over the range of the ensemble members and hence the spread gives a measure of the uncertainty as represented by ORAS4 (which does not cover all sources of uncertainty). The vertical colored bars indicate a two year interval following the volcanic eruptions with a 6 month lead (owing to the 12-month running mean), and the 1997–98 El Niño event again with 6 months on either side. On lower right, the linear slope for a set of global heating rates (W/m2) is given.

On lower right, the linear slope for a set of global heating rates (W/m2) is given.

The Data

In this paper, the authors used ocean heat content data from the European Centre for Medium-Range Weather Forecasts’ Ocean Reanalysis System 4 (ORAS4).  A ‘reanalysis’ is a climate or weather model simulation of the past that incorporates data from historical observations.  In the case of ORAS4, this includes ocean temperature measurements from bathythermographs and the Argo buoys, and other types of data like sea level andsurface temperatures.  The ORAS4 data span from 1958 to the present, and have a high 1°x1° horizontal resolution, as well as 42 vertical layers.  As the authors describe the data set,

“ORAS4 has been produced by combining, every 10 days, the output of an ocean model forced by atmospheric reanalysis fluxes and quality controlled ocean observations.”

Accelerated Global Warming

As illustrated in Figure 1 above, the study divides ocean warming into three layers for comparison – the uppermost 300 meters (grey), 700 meters (blue), and the full ocean depth (violet).  After each of the Mt. Agung, Chichón, and Pinatubo volcanic eruptions (which cause short-term cooling by blocking sunlight), a distinct ocean cooling event is observed in the data.  Additionally, after the very strong El Niño event of 1998, a cooling of the upper 300 and 700 meters of oceans is visible as a result of heat being transfered from the surface ocean to the atmosphere.

One of the clearest features in Figure 1 is the rapid warming of the oceans over the past decade.  As we have previously discussed, the warming of the shallower oceans has slowed since around 2003, which certain climate contrarians have cherrypicked to try and argue that global warming has slowed.  However, more heat accumulated in the deeper oceans below 700 meters during this period.  The authors describe the ocean warming since 1999 as,

“the most sustained warming trend in this record of OHC.  Indeed, recent warming rates of the waters below 700m appear to be unprecedented.”

Their results in this respect are very similar the main conclusion of Nuccitelli et al. (2012), in which we noted that recently, warming of the oceans below 700 meters accounts for about 30% of overall ocean and global warming.  Likewise, this new study concludes,

“In the last decade, about 30% of the warming has occurred below 700 m, contributing significantly to an acceleration of the warming trend.”

The warming of the oceans below 700 meters has also been identified by Levitus et al. (2012) and Von Schuckmann & Le Traon (2011), for example.

Some ‘Missing Heat’ Found

Kevin Trenberth past comments about ‘missing heat’ drew considerable attention.  The phrase refers to the fact that the heat accumulation on Earth since about 2004 (e.g. from warming oceans, air, and land, and melting ice) that instruments were able to measure could not account for the amount of global heat accumulation we expected to see, based on the energy imbalance caused by the increased greenhouse effect, as measured by satellites at the top of the Earth’s atmosphere.

These new estimates of deeper ocean heat content go a long way towards resolving that ‘missing heat’ mystery.  There is still some discrepancy remaining, which could be due to errors in the satellite measurements, the ocean heat content measurements, or both.  But the discrepancy is now significantly smaller, and will be addressed in further detail in a follow-up paper by these scientists.

So what’s causing this transfer of heat to the deeper ocean layers?  The authors suggest that it is a result of changes in winds related to the negative phase of the Pacific Decadal Oscillation and more frequent La Niña events.

Good News for Climate Sensitivity?  Probably Not

Recently there have been some studies and comments by a few climate scientists that based on the slowed global surface warming over the past decade, estimates of the Earth’s overall equilibrium climate sensitivity may be a bit too high.  However, as we previously discussed, these studies and comments tend to neglect the warming of the deep oceans below 700 meters.

Does the warming of the deep ocean support these arguments for lower equilibrium climate sensitivity?  Probably not, as Trenberth explained (via personal communication),

“it contributes to the overall warming of the deep ocean that has to occur for the system to equilibrate.  It speeds that process up.  It means less short term warming at the surface but at the expense of a greater earlier long-term warming, and faster sea level rise.”

So the slowed warming at the surface is only temporary, and consistent with the ‘hiatus decades’ described by Meehl et al. (2011).  The global warming end result will be the same, but the pattern of surface warming over time may be different than we expect.

The real problem is that in the meantime, we have allowed the temporarily slowed surface warming to lull us into a false sense of security, with many people wrongly believing global warming has paused when in reality it has accelerated.

Global Warming Wake Up Call

Perhaps the most important result of this paper is the confirmation that while many people wrongly believe global warming has stalled over the past 10–15 years, in reality that period is “the most sustained warming trend” in the past half century.  Global warming has not paused, it has accelerated.

The paper is also a significant step in resolving the ‘missing heat’ issue, and is a good illustration why arguments for somewhat lower climate sensitivity are fundamentally flawed if they fail to account for the warming of the oceans below 700 meters.

Most importantly, everybody (climate scientists and contrarians included) must learn to stop equating surface and shallow ocean warming with global warming.  In fact, as Roger Pielke Sr. has pointed out, “ocean heat content change [is] the most appropriate metric to diagnose global warming.”  While he has focused on the shallow oceans, actually we need to measure global warming by accounting for all changes in global heat content, including the deeper oceans.  Otherwise we can easily fool ourselves into underestimating the danger of the climate problem we face.

oooOOOooo

“Global warming has not paused, it has accelerated.”

Now I should end it there.  But I can’t!

American readers worried about the drought? Do watch this short video from Paul Douglas. (Apologies for the ad. at the start.)

For worldwide readers who have seen the massive changes in ‘normal’ weather this winter, take a look at this, first published on the NASA Earth Observatory website:

arctic_oscillation_nasa_march_2013

arcticoscillation_2013

While a high-pressure weather system brought warmer than normal temperatures to Greenland and northern Canada in March 2013, much of North America, Europe, and Asia shivered through weeks of unseasonably cool temperatures. The contrasting temperatures are no coincidence: the same unusual pressure pattern in the upper atmosphere caused both events.

Atmospheric pressure patterns are constantly in flux, as air masses of differing temperatures and densities move around the skies. One key measure of pressure that meteorologists track closely is known as the Arctic Oscillation (AO) index, the difference in relative pressure between the Arctic and the mid-latitudes. Changes in the AO have can major impacts on weather patterns around the world.

When the AO index is in its “positive” phase, air pressure over the Arctic is low, pressure over the mid-latitudes is high, and prevailing winds confine extremely cold air to the Arctic. But when the AO is in its ”negative“ phase, the pressure gradient weakens. The pressure over the Arctic is not as low and pressure at mid-latitudes is not as high. In this negative phase, the AO enables Arctic air to flow to the south and warm air to move north.

In late March, the AO dropped as low as -5.6. (See this chart published by the Washington Post’s Capital Weather Gang to see how this compares with other periods when AO values reached record-low levels).

The temperature anomaly map above, based on data from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite, shows how this affected temperatures in the Northern Hemisphere. The map displays land surface temperature anomalies between March 14–20, 2013, compared to the same dates from 2005 to 2012. Areas with above-average temperatures appear in red and orange, and areas with below-average temperatures appear in shades of blue. Much of Europe, Russia, and the eastern United States saw unusually cool temperatures, while Greenland and Nunavut Territory were surprisingly warm for the time of year.

Many parts of the Northern Hemisphere saw near record-breaking cool temperatures as the value of the AO fell. The United Kingdom experienced its 4th coldest March since 1962. In late-March, two-thirds of weather stations in the Czech Republic broke records. Germany saw its coldest March since 1883. And Moscow had its coldest March since the 1950s.

Sorry, I know I went on a bit!

If only we had an alpha dog!

Yearnings for a new start!

You may wonder about the title of this post?  Stay with me for a moment.

As has been written before on Learning from Dogs, when dogs were living in the wild just three animals had pack roles.  The leader of the pack, always a female animal, was the alpha dog. Second in command was the beta dog, always a dominant male, and the third role was the omega or clown dog.  The wild dog pack was thought to have consisted, typically, of about 50 animals.

Pharaoh
The wisdom of thousands of years showing clearly in Pharaoh’s eyes, our very own beta dog.

As leader of her pack an alpha dog had two primary functions .  One was having first choice as to the male dog she was going to mate with – thus demonstrating how women always choose! 😉

Her second important duty was deciding that her pack’s home range was insufficient for the needs of her ‘family’.  As wolves still do, wild dogs lived within small, well-defined territories when food was abundant.  When food became less abundant then it was time to move to more fertile grounds.  As an aside, research in South Africa as to the area requirements for a small pack of African wild dogs (Lycaon pictus) shows they require from 65 square kilometers (25 square miles) to 150 sq. km. (58 sq. mi.). (See footnote.)

Dogs, like all wild animals, instinctively live in harmony with nature.  So the call from the alpha dog to find a new range didn’t mean they left their old one as a barren disaster area.  You can see where this is heading!

Wild dogs were in contact with early man at least 50,000 years ago. (Just reflect for a moment on the length of that relationship between man and dog.) So each specie has had plenty of time to learn from the other.

Thus, as mankind is on the verge of discovering that our existing ‘territory’ is becoming unsustainable for the healthy life of the species,  one fundamental learning point from dogs appears to have escaped us: Mankind doesn’t have a new range available to our species.

This preamble came to mind when I recently read a short but powerful essay on Alex Jones’ blog The Liberated Way.  The essay was called A global leaky bucket.  Alex has very kindly given me permission to republish it.

A global leaky bucket

Global weather extremes will force people to hard choices.

Nature will have the last word in the debate over sustainability.
Nature will have the last word in the debate over sustainability.

I write this in despair, it is snowing again here in Colchester UK.  I admit envy for those of you who live in California or Hong Kong area, I see your photographs where the seasons always seem to be warm and sunny.  The northern Jet Stream refuses to move, Greenland enjoys growing strawberries as the lambs die in the fields of Britain from the winter that refuses to let go.

The extremes of weather are noted in the South of the world as well as the North.  Argentina has had the worst floods in decades last week.  The cause is that the systems such as the Jet Stream are paralysed in one place, thus everyone suffers flood, drought or winter in excess.  Nobody is sure why this paralysis is going on with systems like the Jet Stream, some say it is climate change, the point is that we are experiencing this, and it appears to be more than a temporary issue.

My opinion is that these weather extremes are here to stay for the long duration.  One is then left with a harsh reality of does one seek to control the weather or adapt to the weather? How does one control the weather, a chaotic energy system where even a small change can have great consequences? Perhaps adaptation is the better option, but does one know how huge those adaptations will have to be where drought and flood could be lasting decades?

Lets say food, water and energy are all contained in a bucket.  We take a jug and scoop out from the bucket what we need.  There is a tap that is constantly running filling the bucket with the food, water and energy.  We waste those resources so the bucket leaks.  We disrupt or destroy the renewal systems in the ecosystems so the tap is no longer running as fast as it should.  We are greedy consumers so we take more than we need from the bucket with our jug.  How will the bucket look now? Is this a sustainable future to you?

If our global weather extremes continue as they are it will be like a storm rocking the bucket spilling its contents, will our bucket future look even less sustainable? Extreme weather destroys harvests, kills animals, sends already distressed ecosystems into the abyss.  What happens when the bucket is so empty that people can no longer enjoy their lifestyle of wasteful excess, or worse that people grow cold, hungry and thirsty? Do they sit there and do nothing but die? Will they fight? Who will fight who? As the bucket contents get ever smaller, who will win in the fighting for what is left?

Colchester has a place in my past as I started and ran a business there between the years of 1978 to 1986.  More about that some other day.

Back to Alex’s essay.  It strongly resonated with a recent item on Peter Sinclair’s excellent blog Climate Denial Crock of the Week which I will refer to tomorrow.

So I will leave you with this tragic, emotional thought – where, oh where, is our alpha dog?

Only outcomes matter!

The Resilience Imperative and Civil Disobedience

Introduction

I have long been a subscriber to CASSE, The Center for the Advancement of the Steady State Economy.  As Casse’s home page sets out, “Perpetual economic growth is neither possible nor desirable. Growth, especially in wealthy nations, is already causing more problems than it solves.  Recession isn’t sustainable or healthy either. The positive, sustainable alternative is a steady state economy.”  Do take a minute to see the sense and power of this fundamentally and obvious position by reading a little more here.

But as the title of today’s post sets out, all the ideas and actions and commitments come to naught if the outcomes aren’t delivered.  This recent essay by Michael Lewis on the CASSE website explores the issue of outcomes and I am very grateful for being granted permission to republish it here on Learning from Dogs.

The Resilience Imperative and Civil Disobedience

by Michael Lewis

As I was making a speech in Alberta, Canada, to a business audience, mainly from the finance and energy industries, a fully engaged participant in the front row caught my eye. He was the first to approach me after the question period and the first to get my autograph on The Resilience Imperative: Cooperative Transitions to a Steady-State Economy, the book that I co-authored with Pat Conaty.

During my talk, I had argued that economic growth and a casino-like financial system were taking us to the edge of a deadly precipice. I made the case that societies urgently need to navigate the turn to a steady-state economy, based on local and regional trade. I also offered suggestions on how we might accomplish this. The thesis has a bit of an edge to it, especially in a business crowd accustomed to globalization and growth, so I was anxious to learn more about the front-row enthusiast.

He turned out to be a warm, charming, and open senior manager at Cenovus Energy, a large player in the Athabasca Tar Sands. The corporation seems to be respected in Alberta and Saskatchewan because of its health and safety, community, and environmental initiatives. He rapidly brought the discussion to the issue of “social license,” a condition he acknowledged was a big problem for the tar sands operators. But his view, after many years around boardroom tables, is that the industry is becoming more transparent and responsible, and its performance is improving.

I believe this to be true; certainly Cenovus has been doing a lot of things right. However, I argued that he was missing the point; social license in this industry could only be understood in a global context, and it is not going to be forthcoming for two simple reasons: (1) economic growth produces carbon and (2) carbon is going to kill a lot of us and thousands of other creatures.

If the oil and gas sector wants to explore the potential for broadening its social license, it would have to stand shoulder to shoulder with scientists, governments, businesses, and civil society and argue for a stiff tax on carbon. Only by taking such responsibility can Cenovus and its fellow corporations expand their social license. At the same time they would be helping to set the stage for the transition to a steady-state economy.

“Nothing less would do,” I proclaimed.

“Well you know, Mike,” he replied, “I have not seen much evidence of such a move afoot.”

Why am I not surprised? “I know,” I said. “Shareholder interests are framed by the ideology of growth and profit maximization, and even when these interests are complemented by an ethic of corporate social responsibility, the ideology does not exactly encourage this vital and necessary conversation.”

A few days later I attended the launch conference of the New Economics Institute at Bard College in Upstate New York. It was a remarkable convergence of practitioners, researchers, and activists engaged in debates about economics, analysis of mindboggling challenges (both local and planetary in scale), and exploration of hopeful transformational pathways.

Bill McKibben delivered a Friday evening keynote speech to a packed audience. His laser focus on greenhouse gas emissions was at once absorbing, terrifying, and hopeful, precisely the kind of dynamic that is motivating more and more people to step up to the front lines of civil disobedience, including many scientists and even a few economists. Mark Jaccard, a well-known energy economist in Vancouver, is hardly considered to be a radical, but he joined the front-line battle as part of a 350.org action. He was arrested in May of this year [Ed: 2012] for blocking a coal train headed north to Vancouver’s coal port.

McKibben and Jaccard are picking up on the analysis of James Hansen et al. that oil and gas are a problem, but we do not have enough of it left to take us over 450 parts per million of carbon dioxide in the atmosphere. Coal is the real threat. Unless we phase out coal completely by 2050, we will blast beyond this concentration, and that’s an event that many climate scientists believe will trigger catastrophic consequences. What are we to do?

McKibben and Jaccard are showing us part of the answer. But to make real progress, we need to pay much more attention to Herman Daly, the outstanding chronicler of our economic and ecological lunacy. He concluded one recent essay with this strident statement befitting of our circumstances:

Even though the benefits of further growth are now less than the costs, our decision-making elites have figured out how to keep the dwindling extra benefits for themselves, while “sharing” the exploding extra costs with the poor, the future, and other species. The elite-owned media, the corporate-funded think tanks, the kept economists of high academia, and the World Bank — not to mention Gold Sacks and Wall Street — all sing hymns to growth in perfect unison, and bamboozle average citizens.

Dr. Daly has clarified and expanded the arguments for a steady-state economy that go back to John Stuart Mill, John Ruskin, Frederick Soddy, Kenneth Boulding, and Ghandi. In the same essay referenced above, Daly also noted that in spite of all the evidence of the growing crisis, “our economists, bankers, and politicians still have unrealistic expectations about growth. Like the losing gambler they try to get even by betting double or nothing on more growth.”

Well then, perhaps we need to follow the leads of McKibben, Jaccard, and Hansen, and go get arrested. Perhaps we need to breathe deeply and act courageously to make hope more concrete and despair less convincing. Perhaps those of us in the 50 to 90-year-old set need to commit to civil disobedience to honor our children, grandchildren and our hopes for their survival. The time has arrived for all of us, but especially the post-war “growth generation” to break out of our too-comfortable zones. Stopping carbon emissions is a pre-condition, but nothing will change unless we are prepared to put ourselves on the line.

Of course, this is not enough. We have many questions to answer. How are we going to meet basic needs for energy, food, and shelter? How are we going to finance the economic transition? How do we restructure property rights to overcome the pervasive me-first culture? How do we achieve more local and democratic ownership of the means of production? How do we share jobs and income in a transition that will require less stuff and thus less making of stuff?

These are the questions we concentrate on in The Resilience Imperative. Pat Conaty and I put 42 months of serious forehead pressing into the book, and the early results are gratifying. People as divergent as John Fullerton, former managing director of JP Morgan whose focus is now on resilience and transition (good-bye Wall Street), and Robin Murray from the London School of Economics have endorsed it — they believe we have presented hopeful ideas for getting the transition going.

After presenting numerous positive examples of how people are changing the economy today, we end the book on this note:

The tasks of transition are many. The challenges are daunting. The outcomes are uncertain. Our courage remains untested. But we are a resilient species. We are not alone; there is “blessed unrest” all about. If we but open our eyes, we will SEE change is possible. If we act in ways that recognize we are interdependent, we will continue to innovate co-operative transitions to a steady-state economy.

There is one key question we need to ask ourselves. What stories will we be able to tell our loved ones about what we did to advance the Great Transition?

oooOOOooo

One sentence really jumped out at me from Michael’s essay and it was this one, “Perhaps we need to breathe deeply and act courageously to make hope more concrete and despair less convincing.”  Reminds me of the quotation ascribed to Napoleon Bonaparte:

Courage isn’t having the strength to go on, it is going on when you don’t have strength.

It is all about outcomes.

2020 vision

A moving, sensitive video about the Arctic.

I won’t let on why I called this post ‘2020 vision’ but if you watch the video below to just before the 7-minute mark the use of the number 2020 will become clear.

This video came to my attention from a recent post on Climate Crocks.  It’s a strongly powerful message about the changes going on in Arctic region and the profound effect those changes will have on the rest of the planet.  Indeed, many experiencing the recent weather in North-West Europe will amend the future tense of my sentence to present tense!

You can read more here about Professor Ken Dunton at the University of Texas where he is Professor, Department of Marine Science.

He is the sort of person that we should be listening to very carefully as the world changes in ways not seen for tens of thousands of years.

Sceptical about global warming? Read this!

Learning from Dogs is not a blogsite about climate change!

Why, you may ask, do I start today’s post with that sub-heading?  Because, I am conscious that many of my posts do touch on this subject.  For example, just two days ago there was Breaking news.  Then there was the piece about the climate implications for Phoenix, Arizona.  Followed the next day by the changes in the flow of the jet stream across the North Atlantic with all the weather implications for North-West Europe.

Indeed, as the heading to today’s post makes clear, this is also about the changes going on to our planet.

Learning from Dogs is about a different way of living and behaving.  A campaign, if one wants to call it that, to show that the way that modern man is living is corrupt.  Not with a big ‘C’ but still in the sense of living a dishonest life.  Learning from Dogs attempts to show that our wonderful dogs, a source of so much love and pleasure for so many millions, offer us an example of a life in and of this planet.

If there was ever a time in the history of man when we needed being reminded of our frailty and vulnerability, it is now.  As the following so starkly illustrates.

Peter Sinclair of Climate Crocks recently republished an item from Skeptical Science that opened up as follows:

A new study of ocean warming has just been published in Geophysical Research Letters by Balmaseda, Trenberth, and Källén (2013).  There are several important conclusions which can be drawn from this paper.

  • Completely contrary to the popular contrarian myth, global warming has accelerated, with more overall global warming in the past 15 years than the prior 15 years.  This is because about 90% of overall global warming goes into heating the oceans, and the oceans have been warming dramatically.

But what really jumped off the page was this graph.  It is truly scary!

orasa4
Figure 1: Ocean Heat Content from 0 to 300 meters (grey), 700 m (blue), and total depth (violet) from ORAS4, as represented by its 5 ensemble members. The time series show monthly anomalies smoothed with a 12-month running mean, with respect to the 1958–1965 base period. Hatching extends over the range of the ensemble members and hence the spread gives a measure of the uncertainty as represented by ORAS4 (which does not cover all sources of uncertainty). The vertical colored bars indicate a two year interval following the volcanic eruptions with a 6 month lead (owing to the 12-month running mean), and the 1997–98 El Niño event again with 6 months on either side. On lower right, the linear slope for a set of global heating rates (W/m2) is given.

I’m not going to republish the whole piece, although Peter Sinclair kindly gave permission, because I want to move on.  But please do go to that article here and take in the conclusions; for all our sakes.  Conclusions such as:

Their results in this respect are very similar to the main conclusion of Nuccitelli et al. (2012), in which we noted that recently, warming of the oceans below 700 meters accounts for about 30% of overall ocean and global warming.  Likewise, this new study concludes,

“In the last decade, about 30% of the warming has occurred below 700 m, contributing significantly to an acceleration of the warming trend.”

and such as:

Most importantly, everybody (climate scientists and contrarians included) must learn to stop equating surface and shallow ocean warming with global warming.  In fact, as Roger Pielke Sr. has pointed out, “ocean heat content change [is] the most appropriate metric to diagnose global warming.”  While he has focused on the shallow oceans, actually we need to measure global warming by accounting for all changes in global heat content, including the deeper oceans.  Otherwise we can easily fool ourselves into underestimating the danger of the climate problem we face.

What I want to move on to is a recent item highlighted on Grist.  This was an essay by David Roberts under the heading of Two reasons climate change is not like other environmental problems.  David opens by saying:

If you’ll forgive me for stating the obvious: Most people don’t understand climate change very well. This includes a large proportion of the nation’s politicians, journalists, and pundits — even the pundits who write about it. (I’m looking at you, Joe Nocera.)

One reason for the widespread misunderstanding is that climate change has been culturally coded as an “environmental problem.” This has been, in all sorts of ways, a disaster. Lots of pundits, especially brain-dead “centrist” pundits, have simply transferred their framing and conception of environmental problems to climate. They approach it as just another air pollution problem.

David writes that firstly carbon dioxide is not like other pollutants, for example like air particulants.  Then later goes on to say:

The second difference is that climate change is irreversible.

As Joe Romm notes in a recent post, New York Times columnist Joe Nocera slipped up in his latest column and referred to technology that would “help reverse climate change.” I don’t know whether that reflects Nocera’s ignorance or just a slip of the pen, but I do think it captures the way many people subconsciously think about climate change. If we heat the planet up too much, we’ll just fix it! We’ll turn the temperature back down. We’ll get around to it once the market has delivered economically ideal solutions.

But as this 2009 paper in Nature (among many others) makes clear, it doesn’t work that way:

This paper shows that the climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop. Following cessation of emissions, removal of atmospheric carbon dioxide decreases radiative forcing, but is largely compensated by slower loss of heat to the ocean, so that atmospheric temperatures do not drop significantly for at least 1,000 years. [my emphasis]

The article is really best read in full. Because it’s a reminder that the way we presently behave is, in so many ways, a scary legacy for future generations.

So, back to dogs!

When dogs were living as wild dogs, thousands of years ago, a typical pack size was between 40 to 50 animals. The ‘head’ dog was the alpha dog, always a female.  Next in status was the beta dog, always a dominant male. The last one in terms of status was the omega dog, or clown dog.  Those genetic traits still survive in the domestic dog.

Pharaoh - still being an assertive beta dog; taken 22 days ago!
Pharaoh – still being an assertive beta dog; taken 22 days ago!

The alpha dog had two important roles as ‘leader of the pack’.  She had first pick of the male dogs, for obvious reasons. (Only much later in life do we human men come to understand that it’s always the woman who chooses!)

The second role was that she was the one who decided that their territory was unsustainable for her pack and signalled the need to find a new territory.

For man, there’s no other territory to move to.  So we will just have to clean up the only one we have!
