There is something about a Huskie that takes one’s breath away. Not only because of the grace and wit with which they conduct their lives but also because the majority of them are working dogs.
So it was with interest that I read recently about the Huskies and wanted to share it with you all.

A dog DNA startup company called Embark, based out of Boston, Massachusetts, and Ithaca, New York, appears to have finally solved the mystery as to why huskies sport their beautiful blue eyes. The study is the first consumer genomics study ever conducted in a non-human model, as well as the largest canine genome-wide association study to date, reports Phys.org.
The key, it turns out, lies in the dogs’ 18th chromosome. A duplication on chromosome 18, near the ALX4 gene, was found to be strongly associated with blue eye color. The ALX4 gene plays an important role in mammalian eye development, so this association is not entirely out of left field. And interestingly, the study also found this same genetic quirk in non-merle Australian shepherds, which also tend to have blue eyes.
This flies in the face of how eye color is usually thought to be determined in dogs. For instance, two genetic variants are known to underlie blue eye color in many dogs, but scientists have long known that these variants do not explain the blue eyes of huskies, thus the mystery.
In fact, even though we’re seemingly in a genomic scientific age, the genetic underpinnings of many traits in non-human animals are still largely unknown, even for humans’ best friends. Embark aims to change that.
For the study, which was performed in partnership with Cornell University College of Veterinary Medicine, researchers used a diverse panel of 6,070 genetically tested dogs, with owners who contributed phenotype data — physical traits of the dogs — via web-based surveys and photo uploads. A comprehensive, consumer-driven survey of this size is largely unprecedented.
“Using genetic data from the pets of our customers, combined with eye colors reported by customers for those same animals, we have discovered a genetic duplication that is strongly associated with blue eye color. This study demonstrates the power of the approach that Embark is taking towards improving canine health,” explained Aaron J. Sams of Embark. “In a single year, we collected enough data to conduct the largest canine study of its kind. Embark is currently pursuing similar research projects in a range of morphological and health-related traits and we hope to continue to use our platform to move canine genetics and health forward in a very real way.”
It’s all in the name of improved health care options for our canine companions, as well as helping curious human owners better understand the origins of their pets. Answering why huskies have blue eyes is just the first such mystery they hope to solve.
If you can, please support this PDX event coming up on the 5th.
In my post that was my letter to Mr. Neptune, Colette left a reply that was a ‘heads up’ to an event being held in Portland, Oregon on October 5th. Ergo, this coming Friday.
Now the odds are that very few of you dear readers will be within reach of that event.
But that doesn’t stop me from promoting the event so that the details may be shared as far and wide as possible.
Join us October 5th for a peaceful Demonstration to help endangered Southern Resident Killer Whales. There are only 74 left after the loss of 2 baby Orcas this Summer. You may have seen the dead newborn Orca carried “Save our Orcas”. Meet promptly at Holladay Park at 3:00pm.
ooOOoo
Here’s a news item taken from CBS News.
Then for those that would like more background on the Orca whale, let me republish the opening paragraphs of an item from Wikipedia.
The killer whale or orca (Orcinus orca) is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins. They have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as no animal preys on them. A cosmopolitan species, they can be found in each of the world’s oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas, absent only from the Baltic and Black seas, and some areas of the Arctic Ocean.
Killer whales are highly social; some populations are composed of matrilineal family groups (pods) which are the most stable of any animal species. Their sophisticated hunting techniques and vocal behaviours, which are often specific to a particular group and passed across generations, have been described as manifestations of animal culture.
Wild killer whales are not considered a threat to humans,[6] but there have been cases of captive orcas killing or injuring their handlers at marine theme parks. Killer whales feature strongly in the mythologies of indigenous cultures, with their reputation ranging from being the souls of humans to merciless killers.

Just the view at night from one small planet, the one that I happen to live on, Planet Earth, reveals millions upon millions of stars. It is then beyond inconceivable that there are not, in turn, countless numbers of other planets.
Extending this line of thought and recognising that a ‘mere’ billion years after the formation of our solar system and Planet Earth, some 4.54 billion years ago, the earliest life appeared, we can’t surely be alone!
Granted it was only cyanobacteria, as in blue-green algae, but, but, but ……… that this evolution of life on Planet Earth, and that evolution eventually leading to intelligent life, including the gift to us humans of the genetic separation of the dog from the wolf some 100,000 years ago, has not occurred on other planets is also totally inconceivable.
So, dear Mr. Cosmos, why have we not detected any signs of that intelligent life. Where are they?
Are we alone in the universe? New Drake equation suggests yes
A fresh take on the decades-old Drake equation incorporates new factors and greater uncertainty, suggesting a high likelihood that humanity is alone in the universe.
At the Los Alamos National Laboratory in 1950, physicist Enrico Fermi famously posed to his colleagues a simple question borne of complex math: ‘Where are they?’
He was asking about aliens—intelligent ones, specifically. The Italian-American scientist was puzzled as to why mankind hasn’t detected any signs of intelligent life beyond our planet. He reasoned that even if life is extremely rare, you’d still expect there to be many alien civilizations given the sheer size of the universe. After all, some estimates indicate that there is one septillion, or 1,000,000,000,000,000,000,000,000, stars in the universe, some of which are surrounded by planets that could probably support life.
So, where are they, and why aren’t they talking to us?
Now, as the article reveals, there is a lot to tackling this question, much of it involving statistics and mathematics, but it does prove one very important fact: Finding another planet as good for life and humanity as this one is just about impossible.
This is our only home!!
My wish, dear Mr. Cosmos, to you is this: That before I die it becomes clear beyond question that the peoples of this sweet Planet, from the lone individual living on some island out in the wilderness to the Governments of the most powerful nations on Earth, understand that nothing is more important than loving, caring for and looking after Planet Earth.
I remain, dear Mr. Cosmos, your respectful servant.
The last in this recent series on me examining my navel!
Dear Mr. Cosmos,
Clearly, I have no idea how many letters you receive from us funny inhabitants on Planet Earth. Can’t imagine you get floods of them but then neither can I imagine that this is the first one you have ever received.
Why can I not imagine this is to be your first? Simply, because us funny folk on this incredible planet of yours have been around for quite a while. I mean that over in that country we folk call Israel there has been found evidence of “control of fire by humans nearly 790,000 years ago.”
Whoops!
Just realised that me saying “quite a while” and writing of “790,000 years ago” will be utterly meaningless, in terms of scale, to how you describe your past. Just as it is utterly meaningless for me to contemplate that in cosmological terms the ‘Big Bang”, generally recognised as the start of your Universe, was, give or take, some 13.8 billion years ago.
I wish I could really get an idea of what a million years feels like, let alone a billion years. Ah well!
Let me stay with this notion of stuff being meaningless.
My dear, long-time friend Dan Gomez sent me a link to an item that had been published on the Science Alert website. It was about how the NASA Hubble space telescope had recently embarked on a new mission. Or in the words of that article:
Hubble Just Revealed Thousands of Hidden Galaxies in This Jaw-Dropping Photo
By Michelle Starr, September 13th, 2018
Hubble has embarked on a new observation mission: to study the farthest reaches of the Universe, using some of the most massive objects in the Universe – galaxy clusters.
And this newly released picture shows how.
At the centre is Abell 370, a cluster of a few hundred galaxies located around 4 billion light-years from Earth. And arrayed around it, never seen before, are thousands of galaxies, out even farther in the depths of space.
The reason we can see them now is because of Abell 370. All those hundreds of galaxies, clustered so close together, and the associated dark matter, create an immense field of gravity.
When the light behind that field passes through it, the gravitational force is so strong that it bends the path of the light. This creates a magnifying effect called gravitational lensing, allowing us to see objects we usually can’t.
Abell 370 is the first of these clusters.
Here is one of those photographs,
(NASA, ESA, A. Koekemoer, M. Jauzac, C. Steinhardt, and the BUFFALO team)
And an explanation of what we are looking at:
In the image, you can see the galaxies in Abell 370. The brightest yellowish white ones are huge, containing hundreds of billions of stars. The bluer ones are smaller, spiral galaxies, like the Milky Way, with younger populations of stars. And the dimmer, yellower galaxies are older, with ageing star populations.
The galaxies behind Abell 370 appear as smeared lines of light. The most spectacular, to the lower left of the centre, is nicknamed the Dragon (possibly for its resemblance to a Chinese dragon), with its head to the left. It’s made up of five images of the same spiral galaxy, magnified and stretched by the gravitational lens.
Mr. Cosmos, you know a little earlier I was remarking about how it is impossible to comprehend the age of the Universe. Well, dear Sir, it’s just as impossible to comprehend your distances.
Take Abell 370 out there some 4 billion light years from Planet Earth! I really wanted to have a go at understanding that distance.
First, I looked up the distance in miles that is represented by one light-year. Answer: one light year is a tad under six trillion miles.
Just one, let alone some 4 billion of them!
Next, I looked up the distance of our very familiar Big Dipper constellation. You must have heard of it? This one!
The Big Dipper. Image Credit & Copyright: Jerry Lodriguss
Turns out that even this very familiar sight in our night sky ranges from 78 to 123 light years away. Average that as 100 light years and, bingo, you are looking at this familiar cluster of stars that is 590 trillion miles away!
So, dear Mr. Cosmos, that puts your Abell 370 constellation about a distance that is 10 million times more distant than our Big Dipper!
I wrote above that “I really wanted to understand that distance.” In reference to how far that Abell 370 constellation truly was. My conclusion is that I will never, ever understand that distance.
Anyone able to help?
Tomorrow, Mr. Cosmos, the closing page two of my letter to you.
To be honest, dear friends, I really agonised over whether or not to republish an item that I saw on The Conversation blogsite last Friday. For it has nothing to do with dogs, nothing to do with learning from dogs, and everything to do with being the ‘wrong’ side of 65 years old.
But then one day last week I was out watching some tree cutting being undertaken by Jimmy Gonzales and his crew and heard the phoning ringing in the house.
I ran for the steps leading up to the deck and missed the bottom step.
I fell but luckily managed to grab the handrails seconds before I could have smacked my head into the steps. However, it did scare me especially when I reflected that it wasn’t even 9 months since my medical emergency following my fall from my bicycle.
It confirmed the sense in republishing the item. Republished within the terms of The Conversation site.

Before the fall: How oldsters can avoid one of old age’s most dangerous events
September 21, 2018
By four authors:
Matthew Lee SmithCo-Director of Texas A&M Center for Population Health and Aging, Texas A&M University
Ellen SchneiderResearch Scientist, University of North Carolina at Chapel Hill
Marcia G. OryRegents and Distinguished Professor, Associate Vice President for Strategic Partnerships and Initiatives, Texas A&M University
Tiffany ShubertAdjunct Assistant Professor, Public Health, University of North Carolina at Chapel Hill
Baby boomers, who once viewed themselves as the coolest generation in history, are now turning their thoughts away from such things as partying and touring alongside rock bands to how to they can stay healthy as they age. And, one of the most important parts of healthy aging is avoiding a fall, the number one cause of accidental death among people 65 and older.
The issue is growing more pressing each day. More adults than ever – 46 million – are 65 and older, and their numbers are increasing rapidly.
People who fall can lose their physical mobility for life, go into a hospital never to be discharged, require skilled nursing or other caregiver support, or become so fearful about falling again that they dramatically limit their daily activities.
The good news is that most falls are preventable, research has identified many modifiable risk factors for falls, and older adults can empower themselves to reduce their falls risks. This means there are opportunities to intervene in clinical and community settings to promote protective behaviors and improve safety.
A life-changing event
Falls can cause fractures, traumatic brain injuries and other conditions that require an emergency room visit or hospitalization. An older adult dies from a fall every 19 minutes, and every 11 seconds an older adult is treated in an emergency room for a fall-related injury. About one in four falls results in needed medical attention, and falls are responsible for about 95 percent of all hip fractures. In addition to the physical and mental trauma associated with the fall itself, falls often result in fear of falling, reduced quality of life, loss of independence and social isolation.

There is no single cause for falling. Falls can result from issues related to biological aging, such as balance problems, loss of muscle strength, changes in vision, arthritis or diabetes. Taking a combination of several prescription drugs can also contribute to falls. Lifestyle behaviors such as physical inactivity, poor nutrition and poor sleep quality can also increase the risk for falling. Environmental hazards inside the home, such as poor lighting and throw rugs, and outside, such as bad weather, standing water and uneven sidewalks, can create situations where falls are more likely to occur.
It takes a careful village
Because falls can be caused by many things, the solutions must also include a diverse set of systems, organizations and professionals. Toward that end, 42 active or developing state fall prevention coalitions, which coordinate initiatives and serve as advocates for policy development and community action, are in place. Their activities foster collaboration across the aging services network, public health and health care system. They do such things as host health fairs and fall risk screening events, fall prevention programs, and awareness-raising events to inform decision-makers and legislators about ways to make communities safer for older adults.
Here are some of the key objectives that the coalitions are working on to reduce hazards from falling:
Enhance clinical-community collaboration for programming.
There are many fall prevention programs offered in communities to promote healthful behaviors and to reinforce positive mental perspectives about falls being preventable.
People concerned about falling should contact their local Area Agency on Aging to find out where these programs are offered and which can be most beneficial. Also, seniors should ask their doctors about fall-related risk factors and what they can do to reduce risk. Communicate your concerns about falls with your health care team and social network, tell them about what you learn during your fall prevention programs, and report back about how they are making a difference in your life.
Manage chronic conditions.
About 70 percent of older adults have one or more chronic conditions, many of which can increase the risk for falling. For example, people with diabetes may have vision problems and problems with sensation in their feet. Also, the medications used to treat these conditions can increase fall risk. And, taking five or more medications has been identified with increased frailty and higher risk for falling.
Being physically active can help seniors have better balance and reduce the risk of falls. wavebreakmedia/Shutterstock.com
While health care access and utilization are important for chronic disease diagnosis and management, 90 percent of health care happens outside the health care setting. Therefore, older adults need to manage their diseases better. To do this, however, they often need help. For starters, they should discuss the side effects of all medications with their doctors and also how best to adhere to prescribed treatment regimens, such as when to take medications, whether to take with food and whether there are possible interactions of one medication with another. Seniors also can consider enrolling in evidence-based disease self-management programs to improve their knowledge and confidence to manage their conditions as well as enhance lasting skills for goal setting and action planning, such as being physically active for 30 minutes a day for five days a week.
Alter the physical environment.
About 44 percent of falls occur inside the home. In-home risk factors for falls can include dim lighting, clutter on floors, throw rugs and ottomans, missing railings, uncovered wires and extension cords, children and pets underfoot and unsafe bathrooms. A unsafe bathroom is one with an inappropriate toilet height, high shower or bathtub walls and no grab rails.
To identify possible risks in the home, the CDC created a user-friendly safety checklist that can safeguard older adults by eliminating environmental hazards.
Maintain healthful behaviors.
Daily lifestyle behaviors such as physical activity, nutrition and sleep quality can influence fall risk, and these are never too late to change. Interventions can be successful for people of all ages. Among the most important is physical activity, namely safely performing lower-body exercises to increase strength, balance and flexibility. Additionally, seniors should work with their health care team to have medications reviewed and eyes checked regularly. Also, they should ask about their vitamin D levels and possible nutritional supplementation.

Yes, when it comes to being more careful on our feet once again our dear dogs offer us a much better way: Have four of them!!
Just look at the ease of our dear Brandy scampering through the woods yesterday morning!
Our dear, sorely-missed Pharaoh demonstrating the advantages of four feet!
I closed yesterday’s Letter to the Moon with the last sentence from a recent essay from George Monbiot: “Defending the planet means changing the world.”
Shortly, I will be republishing, with Mr. Monbiot’s generous permission, the whole of that essay.
But first I am going to reproduce in full what arrived via email from George in the early hours of yesterday morning.
I’m contacting you because you’re one of the people who emailed me as part of the overwhelming response to my columns In Memoriam, and Incompetence By Design, where I mentioned that ‘some of us are now mobilising to turn the great enthusiasm for wildlife and natural beauty in this country into political action, and to fight the dismantling of the laws that protect our precious wild places’.
Many of you asked what I meant by ‘Watch this space’. The mobilisation starts next Saturday, in London, with The People’s Walk for Wildlife. It’s not a demonstration, nor a rally – it’s a gentle, family-friendly day. The only kind of strength we need is strength in numbers – to show that many thousands of us care deeply about the vanishing of wild mammals, butterflies, mayflies, songbirds and fish, and that we want the Government to commit properly to protecting those that remain.
On Saturday 22nd September, we’ll gather at Reformers Tree, Hyde Park at 10.00am; entertainment will start at 12 noon. At 1pm we’ll walk from Hyde Park Corner, via Piccadilly, St James, Pall Mall, and Cockspur St, to Whitehall. Please come along if you can. Download the birdsong app to play as we go. Bring friends, dress up as your favourite plant or animal or just come as yourself!
I’m looking forward to walking for the missing millions – I hope you can join me!
George
P.S. If you can’t make it, you can still contribute by adding your message of support to the Walk’s Wonder Wall – every post is valuable proof that you care.
Now on to that post.

Plastic Soup
The problem is not plastic. It is consumerism.
By George Monbiot, published in the Guardian 5th September 2018
Do you believe in miracles? If so, please form an orderly queue. Plenty of people imagine we can carry on as we are, as long as we substitute one material for another. Last month, a request to Starbucks and Costa to replace their plastic coffee cups with cups made from corn starch was retweeted 60,000 times, before it was deleted.
Those who supported this call failed to ask themselves where the corn starch would come from, how much land is needed to grow it or how much food production it will displace. They overlooked the damage this cultivation would inflict: growing corn (maize) is notorious for causing soil erosion, and often requires heavy doses of pesticides and fertilisers.
The problem is not just plastic. The problem is mass disposability. Or, to put it another way, the problem is pursuing, on the one planet known to harbour life, a four-planet lifestyle. Regardless of what we consume, the sheer volume of consumption is overwhelming the Earth’s living systems.
Don’t get me wrong. Our greed for plastic is a major environmental blight, and the campaigns to limit its use are well-motivated and sometimes effective. But we cannot address our environmental crisis by swapping one over-used resource for another. When I challenged that call, some people asked me, “so what should we use instead?”. The right question is “how should we live?”. But systemic thinking is an endangered species.
Part of the problem is the source of the plastic campaigns: David Attenborough’s Blue Planet II series. The first six episodes had strong, coherent narratives. But the seventh episode, which sought to explain the threats facing the wonderful creatures the series revealed, darted from one issue to another. We were told we could “do something” about the destruction of ocean life. We were not told what. There was no explanation of why the problems are happening, what forces are responsible and how they can be engaged.
Amid the general incoherence, one contributor stated “It comes down, I think, to us each taking responsibility for the personal choices in our everyday lives. That’s all any of us can be expected to do.” This perfectly represents the mistaken belief that a better form of consumerism will save the planet. The problems we face are structural: a political system captured by commercial interests and an economic system that seeks endless growth. Of course we should try to minimise our own impacts, but we cannot confront these forces merely by “taking responsibility” for what we consume.
Unfortunately, these are issues that the BBC in general, and David Attenborough in particular, avoid. I admire Attenborough in many ways, but I am no fan of his environmentalism. For many years, it was almost undetectable. When he did at last speak out, he consistently avoided challenging power, either speaking in vague terms or focusing on problems for which powerful interests are not responsible. I believe this tendency may explain Blue Planet’s skirting of the obvious issues.
The most obvious is the fishing industry, that turns the astonishing lifeforms the rest of the series depicted into seafood. Throughout the oceans, this industry, driven by our appetites and protected by governments, is causing cascading ecological collapse. Yet the only fishery the programme featured was among the 1% that are in recovery. It was charming to see how Norwegian herring boats seek to avoid killing orcas, but we were given no idea of how unusual it is.
Even marine plastics is in large part a fishing issue. It turns out that 46% of the Great Pacific Garbage Patch, that has come to symbolise our throwaway society, is composed of discarded nets, and much of the rest consists of other kinds of fishing gear. Abandoned fishing materials tend to be far more dangerous to marine life than other forms of waste. As for the bags and bottles contributing to the disaster, the great majority arise in poorer nations, without good disposal systems. But because this point was not made, we look to the wrong places for solutions.
From this misdirection arise a thousand perversities. One prominent environmentalist posted a picture of the king prawns she had just bought, celebrating the fact that she had persuaded the supermarket to put them in her own container, rather than a plastic bag, and linking this to the protection of the seas. But buying prawns causes many times more damage to marine life than any plastic in which they are wrapped. Prawn fishing has the highest rates of bycatch of any fishery: scooping up vast numbers of turtles and other threatened species. Prawn farming is just as bad, eliminating great tracts of mangrove forests, crucial nurseries for thousands of species.
We are kept remarkably ignorant of such issues. As consumers, we are confused, bamboozled and almost powerless. This is why corporate power has gone to such lengths to persuade us to see ourselves this way. The BBC’s approach to environmental issues is highly partisan, siding with a system that has sought to transfer responsibility for structural forces to individual shoppers. It is only as citizens, taking political action, that we can promote meaningful change.
The answer to the question “how should we live?” is “simply”. But living simply is highly complicated. In Aldous Huxley’s Brave New World, the government massacred the Simple Lifers. This is generally unnecessary: today they can be safely marginalised, insulted and dismissed. The ideology of consumption is so prevalent that it has become invisible: it is the plastic soup in which we swim.
One-planet living means not only seeking to reduce our own consumption, but also mobilising against the system that promotes the great tide of junk. This means fighting corporate power, changing political outcomes and challenging the growth-based, world-consuming system we call capitalism.
As the famous Hothouse Earth paper published last month, that warned of the danger of flipping the planet into a new, irreversible climatic state, concluded, “incremental linear changes … are not enough to stabilize the Earth system. Widespread, rapid, and fundamental transformations will likely be required to reduce the risk of crossing the threshold”. Disposable coffee cups made from new materials are not just a non-solution. They are a perpetuation of the problem. Defending the planet means changing the world.
The idea of writing a letter to the moon is not a new one and it came to me when listening to an item yesterday morning, Pacific Time, broadcast by the BBC on Radio 4. The item was the news that Elon Musk has announced that:
Elon Musk’s company SpaceX has unveiled the first private passenger it plans to fly around the Moon.
Japanese billionaire and online fashion tycoon Yusaku Maezawa, 42, announced: “I choose to go to the Moon.”
The mission is planned for 2023, and would be the first lunar journey by humans since 1972.
On September 18, 1977, as it headed toward the outer solar system, Voyager 1 looked back and acquired a stunning image of our Earth and moon.
You will surely remember that first image taken of the Planet Earth and your good self in the same frame.
Here is the 1st-ever photo of the Earth and moon in a single frame. Voyager 1 took the photo on September 18, 1977, when it was 7.25 million miles (11.66 million km) from Earth. Image Number: PIA00013 via NASA/JPL.
Now here we are some 41 years later and, my, how things have changed.
But something, dear Mr. Moon, has never changed for you. That is the sight of our most beautiful planet. Plus, I would go so far as to venture that what makes our planet such a beautiful sight, one that has captivated us humans when we have gone into space and looked back at home, is the magic of our atmosphere.
Picture taken by a NASA satellite orbiting the earth some 200 miles above the planet’s surface.
So, so thin …. and so, so fragile.
It is akin to the thinness of the skin of an onion.
In fact, Mr. Moon, that layer that we earthlings call the troposphere, the layer closest to Earth’s surface varies from just 4 miles to 12 miles (7 to 20 km) thick. It contains half of our planet’s atmosphere!
Everything that sustains the life of air-breathing creatures, human and otherwise, depends on the health of this narrow layer of atmosphere above our heads. Now the thickness of that layer varies depending on the season and the temperature of the air. But let’s use an average thickness of 8 miles (say, 13 km) because I want to explore in my letter to you some comparisons.
In your infinite gaze down upon your mother planet you will have seen the arrival of H. sapiens, out of ancestral H. erectus, that took place roughly 315,000 years ago.
You will also have seen from your lofty vantage point the growth of both CO2 levels in the planet’s atmosphere and the average land-ocean temperature. Forgive me quoting something at you, but:
OBSERVABLE CHANGES IN THE EARTH
SINCE THE INDUSTRIAL REVOLUTION
While politicians have been busy debating the merits of climate science, the physical symptoms of climate change have become increasingly apparent: since the industrial revolution, sea level has grown by 0.9 inches, the atmospheric concentration of carbon dioxide has risen to unprecedented levels, average global temperatures have increased by about 1.0 degree Celsius and, to top it off, the global population has jumped by nearly 600 percent; 15 of the 16 hottest years on record occurred in the 21st century, and 2016 is likely to be the warmest year ever recorded.
Now the Industrial Revolution was all but over back in 1840 and the last 178 years have seen an explosion in the way we use energy, in all its forms. Plus we have to accept that back then the global population was around 1 billion persons. It is now over 7 billion.
Between 1900 and 2000, the increase in world population was three times greater than during the entire previous history of humanity—an increase from 1.5 to 6.1 billion in just 100 years.
So on to my comparisons.
The radius of our beautiful planet is about 3,959 miles (6,371 km). The average thickness of the troposphere is 8 miles (13 km).
Thus the ratio of thickness of our liveable atmosphere to the radius of the planet is 8 divided by 3,959. That is a figure of 0.002! Our atmosphere is 1/1000th of the size of the radius of our planet.
Hang on that figure for a moment.
In the last 178 years humanity has transformed our consumption of energy and especially carbon-based fuels. H. sapiens has been around for 315,000 years.
Thus the ratio of these present ‘modern’ times (the last 178 years) to the arrival of us back then (315,000 years ago) is 178 divided by 315,000. That is a (rounded) figure of 0.0006. Our modern times are just 1/10,000th of the time that so-called modern man has been on this planet.
So, dear Mr. Moon, you must despair that in so short a number of years, proportionally ten times smaller than the ratio of the troposphere to the radius of our planet, we funny creatures have done so much damage to what we all depend on to stay alive – clean air!
Or maybe, my dear companion of the night sky, because you are celebrating your 4.1 billionth year of existence, what we humans are doing is all a bit of a yawn.
Sincerely,
This old Brit living in Oregon.
ooOOoo
My dear friends (and I’m now speaking to you dear reader, not the moon!) when you reflect on the fragility of our atmosphere, well the layer we depend on for life, you realise without doubt that each and every one of us must make this pledge.
“I promise to do everything possible to reduce my own personal CO2 output and to ensure that both to my near friends and my political representatives I make it clear that we must turn back – and turn back now!”
Or, as George Monbiot writes in closing a recent essay (that I am republishing tomorrow): “Defending the planet means changing the world.”
Venturing into strange lands.
A collection of items has been crossing my ‘in-box’ in recent weeks and while many of the topics are, on the face it, not connected, for reasons I am not entirely sure about they seem to fall under the same umbrella; as in being of the same coherent theme.
Let me list some of these topics: the age of the universe; climate change; CO2 levels; the certainty of death; the history of the last half-million years; what our dogs teach us; and more!
Naturally, Jeannie and I have been kicking around these topics, aided and abetted by Dan Gomez, my Californian friend of some 40 years (and my ‘Best Man’ when Jean and I were married in 2010 and, more or less directly, the catalyst of me and Jean meeting in 2007!)
But I get the sense that many of you wonderful people that follow this place also scratch your head not infrequently and ponder on these ‘interesting’ times.
I don’t have any answers. But I do want to share how, over the last few weeks, I have been seeking some meaning, some peace, to the big issues that have the potential to make these times pretty uncomfortable if not a tad scary.
I shall not be extending this introspection each day but probably ( and I’m guessing) a couple of times a week I shall be dipping into the barrel!
Starting off with climate change, maybe tomorrow or Wednesday.
But what of today!
Today I am publishing another Dog Food Recall alert that came out late last week!
ooOOoo
Performance Dog Pet Food Recall
September 12, 2018 — Bravo Packing, Inc. of Carneys Point, New Jersey, is recalling all Performance Dog products, a frozen raw pet food, because they have the potential to be contaminated with Salmonella.
What’s Recalled?

About Salmonella
Salmonella can cause illness in animals eating the products, as well as people who handle contaminated pet products, especially if they have not thoroughly washed their hands after having contact with the products, infected animals or any surfaces exposed to these products.
Healthy people infected with Salmonella should monitor themselves for some or all of the following symptoms: nausea, vomiting, diarrhea or bloody diarrhea, abdominal cramping and fever.
Rarely, Salmonella can result in more serious ailments, including arterial infections, endocarditis (an infection of the heart muscle), arthritis, muscle pain, eye irritation and urinary tract symptoms.
People who have these symptoms after having contact with this product or an animal that has eaten this product should contact their healthcare providers.
Pets with Salmonella infections may be lethargic and have diarrhea or bloody diarrhea, fever, and vomiting.
Some pets will have decreased appetite, fever and abdominal pain.
Pets exposed to contaminated food can be infected without showing symptoms.
If your pet has consumed the recalled product and has these symptoms, please contact your veterinarian.
Infected animals can also shed Salmonella through their feces and saliva, spreading pathogens into the home environment and to humans and other animals in the household.
No human or animal illnesses have been reported to date.

In the past, studies have disagreed on whether forests with lower or higher canopies will be more likely to make it through prolonged spells of hot, dry weather. The discrepancy has made it difficult for forest managers, who need to know which tree heights to encourage to ensure the highest growth and survival rates during extreme drought.
Study leader Peipei Xu at Beijing Normal University in China and her colleagues believe the issue is increasingly pressing. “Climate data indicate that warm areas of land are increasing, and the warmed areas are also drying,” says Chuixiang Yi at the City University of New York, US. “Hot-dry-induced forest mortality poses a significant global concern for the future as carbon dioxide continues to rise and the climate continues to warm.”
Xu, Yi and the rest of the team aimed to quantify the relationships between canopy height, growth and survival rates during drought accurately for the first time. They analysed data gathered during a severe drought in the southwestern US in 2002 that showed the effect on the ring widths of tree trunks, a useful indicator of their yearly growth. In addition, satellite data revealed how the density of vegetation changed over the course of the drought; the team used this to calculate both leaf growth and tree mortality rates.
The results revealed that trunk and leaf growth under drought conditions increased with canopy height for trees shorter than 18 metres but decreased with height for trees taller than 18 metres. “Our results indicate that both high and small trees have relatively low drought resistance,” says Yi.
After establishing these relationships, the researchers could determine the biological mechanisms governing tree growth and survival during drought.
“All organic matter in a tree is formed on the leaves at the top of the tree by photosynthesis,” Yi explains. “Tall trees have a longer water transport path from roots to leaves and [it’s] more difficult to overcome tissue resistance and … gravity, particularly under dry conditions. The roots of small trees are short, and their abilities to access water and nutrient supplies unavailable to the surface soil layer are extremely limited.”
The researchers believe that using their results to inform the active management of canopy structure could safeguard vulnerable forests. As climate models predict hotter, drier droughts becoming more commonplace, this could be essential to combat forest dieback – a phenomenon that will also drive climate change.
“Our findings provide insights into how to manage forests or plant what trees to increase forest drought resistance in facing hot-dry climate conditions to mitigate climate change,” says Yi.
