Breaking news!

Recent news items reinforce messages from yesterday’s book review.

In my review published yesterday of Martin Lack’s book Denial of Science, I wrote, “the continuing and accelerating loss of the Arctic ice-cap“.  Back on the 22nd in More new tomorrows, I included:

A study published in 2012 showed that by changing the temperature balance between the Arctic and mid-latitudes, rapid Arctic warming is altering the course of the jet stream, which steers weather systems from west to east around the northern hemisphere. The Arctic has been warming about twice as fast as the rest of the Northern Hemisphere, due to a combination of human emissions of greenhouse gases and unique feedbacks built into the Arctic climate system. The jet stream, the study said, is becoming “wavier,” with steeper troughs and higher ridges.

A new study published in the journal Environmental Research Letters shows that reduced sea ice cover can favor colder and stormier winters in the northern midlatitudes. [my emphasis – UK readers will need no reminding of this!]

So bear those references in mind as you read:

Breaking News (Literally): NOAA Video Confirms Early Breakup

March 23, 2013

Compare to our recent discussion of these developments in the Beaufort Sea.

NOAA Visualizations:

Published on Mar 22, 2013

A series of intense storms in the Arctic has caused fracturing of the sea ice around the Beaufort Sea along the northern coasts of Alaska and Canada. High-resolution imagery from the Suomi NPP satellite shows the evolution of the cracks forming in the ice, called leads, from February 17 — March 18 2013. The general circulation of the area is seen moving the ice westward along the Alaskan coast

“Intense storms” are not an unheard of thing in the arctic. What’s new is that the ice is so fragile that normal storm activity is breaking it up much earlier than has been seen in the past.

Arctic Sea Ice Blog:

To recapitulate: It is normal for the ice to crack and for leads to occur. However, this is very extensive cracking and there are some very big leads, and all of it seems to come earlier than expected. Given last year’s melting mayhem and the low amount of multi-year ice, it makes one wonder whether this early cracking will have any effect in the melting season to come.

There are still several weeks to go before this part of the Arctic is going to start melting, up till then the ice will actually thicken some more, even when the Sun’s rays start to reach the ice. But the ice is already getting broken up in smaller pieces, which means that 1) the pack becomes more mobile (like we saw last year), and 2) the thin ice that now grows to fill up the leads will go first when the melting starts, potentially leading to more open water between floes to absorb solar energy and convert it to heat.

But maybe not. Maybe this will have zero influence. We don’t know. That’s why we watch.

Nothing more to add except to ponder on what strange weather we will be experiencing this year!  Actually, no need to ponder.  The UK Met Office issued a weather warning last Sunday that included this sentence, “Cold easterly winds will persist through the coming week with bitterly cold conditions.”  That came on the back of a blog entry from the Met Office that same day that included:

Many areas also saw strong winds, with a gust of 61 mph recorded at Shap, Cumbria and 48 mph recorded at Machrihanish, Argyll . These winds have caused even deeper drifts of snow in some areas. [my emphasis].

61mph?  That’s Storm Force 10 under the Beaufort scale and 3mph under the lower boundary of a Violent Storm; Beaufort Force 11!

oooOOOooo

The next item that caught my eye was some ‘goodish’ news from the US Senate via a recent post on 350.org.

Bill’s Response to the Senate Vote Today

Posted by Duncan Meisel – 03/22/13, 4:51pm

Friends,

After a very chaotic week on Capitol Hill, I wanted to write you with an update on what just happened in the Senate today.

First and foremost: the oil industry’s Senators did not manage to pass legislation that would force President Obama to build Keystone XL.

Because you — and people like you, all across the country — jumped into action this week, they backtracked and instead held a vote on a nonbinding resolution that says it would be nice to build the pipeline, but doesn’t actually do much about it. For that vote, they got the stomach-churning number of 62 Senators to vote with them. As usual, the ones who had taken the most money from the fossil fuel industry lined up to cast their votes—the cosponsors of the bill, on average, had taken $807,000 in dirty energy money.

Now, this amounts to symbolic chest thumping by the oil industry: showing just how many Senators they can get to jump when told to. It’s not the worst thing that could have happened, but it reminds everyone why, in one recent poll, congress had approval ratings lower than head lice and colonoscopies — even on the symbolic stuff, they can’t get it together to stand up to the oil industry guys cutting them checks.

In a certain way though, this vote couldn’t come at a better time. Congress is going on break, and for the next two weeks, these 62 Senators will be back in their home states, doing things like meeting with constituents — people like you.

Home states are where some of the most heroic work took place the last week — in Minneapolis, say, where 150 350MN.org activists showed up on very short notice at Sen. Klobuchar’s office in a snowstorm to tell her to vote no on Keystone (and she did, it should be added).

If you’re interested in following in the fine example of those leaders who held actions at their senators offices, you have a chance in the next two weeks.

We’re looking for people who can step up to lead, and then we’ll put the 350 network into action to get people to join you. If you want to lead an action, just click here to tell us when you’d like to do so: act.350.org/survey/kxl-senate-accountability-2013/

Look, there are two ways to react to a democracy for sale. One is to walk away in disgust, which is what the Koch Brothers count on. The other is to stand up and say: no more. If you visit your Senator, take some pictures or some video so we can share them around. It’s time to build this broader fossil fuel resistance.

And remember, Capitol Hill is not the center of the world. Around the country this week our friends at Tar Sands Blockade have been actively targeting Keystone investors; faith groups have been hauled off to jail in front of the White House to protest the pipeline; and the divestment campaign has expanded off college campuses and into municipal and state governments.

The movement is doing amazing stuff — we just need more of it. We can’t outspend the oil industry, but we can out-organize them. In fact, we have to.

Forward,

Bill McKibben

oooOOOooo

“the cosponsors of the bill, on average, had taken $807,000 in dirty energy money.”  Words utterly fail me!

Funny old world!

The Denial of Science: A review.

A review of the recently published book by Martin Lack.

denial of science

In many ways it would be terribly easy to find fault with this book. If it had been written as a book, been through the edits that a new book requires, then published, those faults would be a significant criticism.

But it was not written as a book! It was originally written as an academic text.  As Martin explains in the Preface:

This book is based on research originally undertaken – and a dissertation written – as part of my MA in Environmental Politics from Keele University in Staffordshire (in 2010-2011).

Then in the following paragraph goes on to say:

Academics generally disapprove of the publication of academic research via non-academic, non-peer-reviewed routes.  However, I am trying to reach more than just an academic audience.

Three sentences later:

However, this book retains many of the features of a piece of academic research, …. (All quotes from page viii of the preface)

To a person unaccustomed to reading academic research, as is this reader, the structural and presentational differences between a ‘normal’ non-fiction book and a dissertation are significant.  That needs to be borne in mind as you turn to page one.

OK, now that I have got that off my chest, on to the substance of the review.

Turning to the outside back cover, one sees Martin clearly explaining that the book is not about climate science, rather an analysis of why some people dispute “the reality, reliability and reasonableness of this science.”

That alone justifies the work that Martin put into his research and dissertation and his subsequent decision to adapt his findings into a book.

The pace and scale of the changes that are being visited on Planet Earth is truly frightening.  The number of feedback loops that we are locked into now don’t even bear thinking about.  Just take the continuing and accelerating loss of the Arctic ice-cap and extrapolate that for a couple of decades (touched on in my recent post More new tomorrows and see footnote.)

We are not talking of subtle changes over many generations. We are talking about irreversible and irrevocably massive changes to our environment within the lifetimes of just about every living person on this planet.  (I’m 70 next year and while I have no idea how many years I have left, I rate it as at least 50:50 that before I take my last breath, the coming destruction of biosphere will be blindingly obvious to me, Jean and 99.9% of the world’s population.)

Makes me want to shout out ……

There is not much time left to leave a sustainable world for future generations.  Come on politicians and power-brokers; start acting as though you truly understand the urgency of the situation!

Ah, that feels much better!

Back to the book!

Martin examines 5 categories that display denial behaviours, to a greater or lesser extent.  These categories are: Organisations; Scientists, Economists, Journalists and Politicians. Oh, and a 6th catch-all category: Others.

Each section dealing with a category is structured in the same way: Preliminary Research; Key Findings and Summary.  Tables are used extensively to allow easy review of the findings.

Again, what needs to be hammered out is that this format is very unlike a typical non-fiction book.  Because it’s fundamentally an academic dissertation!  But, so what!

What is important is for the widest possible audience to understand the breadth and extent of the denial going on.  Denial that is, literally, playing with the future of humanity on this planet; the only home we have.

Let me reinforce that last sentence by picking up on what Martin writes on his closing page (p.76):

Furthermore, there is strong circumstantial evidence to suggest that this scepticism is being fuelled by those with a vested interest in the continuance of “business as usual” by seeking to downplay, deny or dismiss the scientific consensus on the extent of ACD.

Martin Lack’s book may be unconventional in many ways.  But as a tool to show how those who deny the science of climate change deny the right of future millions to live in a sustainable manner, it is most powerful.  It is a valuable reference book that should be in every library and every secondary school across the globe!

The Denial of Science is published by AuthorHouse 02/23/2013

More new tomorrows.

New world order goes to ramming speed!

We spent some enjoyable time with neighbours Dordie and Bill yesterday afternoon from where my sub-heading quote comes.  Perhaps, a tad tongue-in-cheek, but only a tad!

Yesterday, the bulk of my post The new tomorrows consisted of a powerful essay from William deBuys ‘Phoenix in the Climate Crosshairs‘, courtesy of TomDispatch.  It painted in very stark terms the impact of climate change on the metropolitan city of Phoenix in Arizona; a city of over 4 million people, indeed home to more than two-thirds of Arizona’s population.

So, today, I wanted to wander through some other aspects of this new world order.

Here’s a recent item on Climate Crocks examining the changes in March’s weather, 2013 vs 2012.  From which I quote:

Much Different March. Same Reason?

Dittohead reasoning: “So when it’s warm, you blame it on climate change. When its cold, you blame it on climate change. It can’t be both.”

Well, yeah, it can, kinda.

Meteo people weigh in.

7Weather Blog WHDH-TV:

I think we’ve passed the point of tolerance with these ceaseless storms. Gone are the days when viewers would flood our inboxes with pretty pictures of their pets and kids frolicing in the snow. Constant cleanup has made us snippy and short – even a few plow guys have hoisted the white flag. The holidays are long past, the winter is stale, and the people just want spring…

…and accountability.  Instead of pictures, I get questions in my inbox. “Why are we getting so much snow? Why did it turn on a dime? And when will it stop?”

Those are fair questions. But with the limits of the long range (10-14 day) forecasts, I’m not ready to answer the last question. We may sail out of this in April, but so far the first week of the month isn’t looking much different from the first week in March. The ultimate question is why.

The jetstream has taken on an odd path. [my emphasis]

Now just look at this:

Later on that article says:

Recent research suggests that rapid Arctic climate change, namely the loss of sea ice cover, may be contributing to blocking patterns like we’re seeing right now. That rapid decline in Arctic sea ice since the beginning of the satellite record in 1979 may be altering weather patterns both in the Far North and across the U.S.. Some studies have shown that sea ice loss favors atmospheric blocking patterns such as the pattern currently in place, while others have not shown statistically significant changes in blocking patterns across the Northern Hemisphere, at least not yet. Arctic sea ice extent declined to a record low during the 2012 melt season.

The last Winter in North-West Europe has been ‘interesting’, to say the least!  A follow-up to that Climate Crock’s essay reports:

A study published in 2012 showed that by changing the temperature balance between the Arctic and mid-latitudes, rapid Arctic warming is altering the course of the jet stream, which steers weather systems from west to east around the northern hemisphere. The Arctic has been warming about twice as fast as the rest of the Northern Hemisphere, due to a combination of human emissions of greenhouse gases and unique feedbacks built into the Arctic climate system. The jet stream, the study said, is becoming “wavier,” with steeper troughs and higher ridges.

A new study published in the journal Environmental Research Letters shows that reduced sea ice cover can favor colder and stormier winters in the northern midlatitudes

Did you fully take in that paragraph?  The one about “The Arctic has been warming about twice as fast as the rest of the Northern Hemisphere …“?

The other great ‘river’ in the North Atlantic is the thermohaline circulation or to put it in more familiar terms: The Gulf Stream.  Has that been changing?  You bet! In more ways than one might expect.

Here’s a snippet from an item from last October’s issue of Nature journal:

Recent changes to the Gulf Stream causing widespread gas hydrate destabilization

The Gulf Stream is an ocean current that modulates climate in the Northern Hemisphere by transporting warm waters from the Gulf of Mexico into the North Atlantic and Arctic oceans. A changing Gulf Stream has the potential to thaw and convert hundreds of gigatonnes of frozen methane hydrate trapped below the sea floor into methane gas, increasing the risk of slope failure and methane release.

How the Gulf Stream changes with time and what effect these changes have on methane hydrate stability is unclear. Here, using seismic data combined with thermal models, we show that recent changes in intermediate-depth ocean temperature associated with the Gulf Stream are rapidly destabilizing methane hydrate along a broad swathe of the North American margin.

As the diagram below shows all too clearly, the cold waters from above the Arctic circle directly affect the Gulf Stream.

gulfstream

From the website of the National Snow & Ice Data Center:

Average sea ice extent for February 2013 was 14.66 million square kilometers (5.66 million square miles). This is 980,000 square kilometers (378,000 square miles) below the 1979 to 2000 average for the month, and is the seventh-lowest February extent in the satellite record.

Less ice means more cold water. QED!

OK, moving on.

We met recently with Wayne over at Rogue Valley Firewood here in Merlin.  Not to buy more firewood but because Wayne has started into hugelkultur.  Jean and I hadn’t heard of the term before.  Come back to that in a moment.

In musing with Wayne about how rapidly life is changing for us all, he spoke of the consequence of rising fuel prices and the rising costs of putting petrol (OK, he used the word ‘gas’!) in one’s car.  Wayne pointed out the obvious.  That the inevitable effect of those rising costs would be to steadily reduce one’s range for ‘affordable’ car journeys.  Many people will no longer be able to afford to drive longer distances.

In other words, local will increasingly become more relevant to daily life.  Or to use a better word than local, community will return to the centre stage of our world.  And of all the things important to a community, none is more so than access to food.

Back to Hugelkultur. Watch this video:

Wayne is committed to seeing just what can be grown for the local community of Merlin using this form of raised garden bed.  You can read more here.

Is this just a piece of fun?  Most definitely not!

Here’s a recent item from Grist.

This sobering map shows you all of America’s food deserts

By Sarah Laskow

The USDA’s new Food Access Research Atlas is a map of all the places in the country where people live in food deserts — places where it’s difficult to access fresh food.

food-deserts1

More details here.

The message that hits me from that map is the consequence for millions of people, especially those in rural areas or unable to afford a car, when it comes to getting hold of fresh food.  Another reason why community food programs are going to be a feature of the new tomorrows.

Finally, take a look at a recent item on Paul Gilding’s blogsite.

paulgildingportrait
Paul Gilding

Paul is an independent writer, advisor and advocate for action on climate change and sustainability. He recently published Victory at Hand for the Climate Movement? From which I offer:

There are signs the climate movement could be on the verge of a remarkable and surprising victory. If we read the current context correctly, and if the movement can adjust its strategy to capture the opportunity presented, it could usher in the fastest and most dramatic economic transformation in history. This would include the removal of the oil, coal and gas industries from the economy in just a few decades and their replacement with new industries and, for the most part, entirely new companies. It would be the greatest transfer of wealth and power between industries and countries the world has ever seen.

To understand this incredible potential we first have to step back and understand the unique structure of this social change movement, which may rank among the most influential in history. It is simplistic to characterise it as an alliance of grass roots organisations and activists pitched against a rich and well connected adversary. While that is part of the story, it is more accurately understood as an idea whose tentacles reach into every tier of government, the world’s largest companies and financial institutions, and throughout the academic and science communities.

Because of this, it is winning the battle from within: Its core arguments and ideas are clearly right; being endorsed by the world’s top science bodies and any significant organisation that has examined them.

Strikes me that in one very important way, we will be reverting to how our ancient hunter-gatherer ancestors lived.  I mean reverting to living our lives as relatively small interdependent communities almost exclusively at the local level.

Guess what!  Yet another aspect of learning from dogs.  In the wild, dogs live in groups of about 50 animals with clear boundaries to their territory.  Just like the ancestors of the domesticated dog and the wild dog: The grey wolf Canis Lupus.

A mathematical approach to the demise of the Neanderthals.

Pure mathematics is, in its way, the poetry of logical ideas. Albert Einstein.

I have never been proficient at mathematics. But that doesn’t mean that I am not fascinated by the field of maths.

Hold that in your thoughts as I mention the name of blogger: Patrice Ayme.  It’s a non-de-plume but so what!  What blows me away, to use the vernacular, is the depth of thought expressed through the keyboard of Mr. Ayme (even the gender is an assumption).  The sub-heading on the home page of his blog is “Intelligence at the core of humanism“.  Just run your eye down the list of Recent Posts to the right-hand side of the home page to get a feel for the topics covered in the last few months.  Impressive is an understatement!

Anyway, five days ago Patrice published a post proposing how the Neanderthals were outbred, under the title of Math Extinguished Neanderthals.  It fascinated me and Patrice was gracious in allowing me permission to republish it on Learning from Dogs.

oooOOOooo

Math Extinguished Neanderthals

HOW NEANDERTHALS WERE OUTBRED:

Zillions of theories about the “disappearance” of Neanderthals. The latest one, from Oxford University, claims that Neanderthals’ big, beautiful eyes, and their big muscles caused their demise. They were too busy looking at things, and flexing their muscles. The idea is that significantly larger eyes would have crowded the Neanderthal brain out, making them relatively stupid. In particular it made them incapable of having social groups as large as those of Homo Sapiens Sapiens.

Big Eyes Do Not Kill

Big Eyes Do Not Kill

Sapiens girl on the left, Neanderthal girl on the right (reconstitution published in Science Magazine a few years ago).

I have long argued that the strength of democracy came from having many brains working in parallel. There is little doubt that larger social groups bring a higher cultural intelligence, hence higher individual intelligence. So I agree about that bit of logic. Yet, ironically, to reach the conclusion that Neanderthals’ social group were less numerous, the simple fact that Neanderthals were bigger, is enough. There is no need for hazardous demeaning allegations about Neanderthals’ brains.

That big eyes made Neanderthals stupid contradicts some facts that were thought to be established:

1) Sapiens Neanderthalis’ brains were significantly larger to start with. See Wikipedia.

2) Many very clever Homo Sapiens Sapiens have small brains. Famously Anatole France, an intellectual, had only a 1,000 cubic centimeters brain. Homo Floresiensis, the “hobbit” species living on the island of Flores, Indonesia, until it was wiped out recently, was extremely intellectually capable, although it had really small (and completely different) brains.

3) In the Middle East, Neanderthals and Sapiens went back and forth through the same large caves over 50,000 years. So whatever happened, it was not in evidence for 50,000 years.

So, of course, I have my own theory. That’s what philosophy is all about: trying to guess what really matters most, and how that most significant data logically articulate. Then scientists, politicians and writers can swoop, figure out the details, and attribute themselves the glory.

What could have happened by around 28,000 years ago that caused the demise of Neanderthals? At the time, the last fierce glaciation was gaining ground. (It reached its maximum 25,000 years ago.) Some have argued, absurdly, that the Neanderthals could not take it. That’s beyond silly, as Neanderthals had evolved, from half a million years ago, precisely to handle extreme cold.

Neanderthals were stocky, powerful, and they had thrived through hundreds thousands years of glaciation, mostly on a meat diet, hunting big game. But they also knew how to cook plants, and eat them.

50,000 years ago, Neanderthals exterminated Cave Bears, a huge animal who lived in caves, prime real estate Neanderthals craved for. Could the disappearance of Cave Bears be logically linked to the disappearance of Neanderthals? Yes. That’s a consequence of my theory. More advanced technology played a direct role.

How did Neanderthals kill Cave Bears? With technology. We do not know exactly what weapons Neanderthals had at their disposal. However, technology had improved, and kept improving. Recently it was found that Sapiens Sapiens (Homo SS; I hope one gets the joke) in Africa had invented bows and arrows 80,000 Before Present (BP).  (About 60,000 years earlier than previously thought!) Before bows and arrows, the propeller had been invented, and was used in Europe. The propeller took advantage of angular momentum to send a sort of mini lance further and stronger than by hand.

Why did the Neanderthals and Denisovans (another human species from Central Eurasia) lose their edge? Advancing technology is the obvious answer. When technology of clothing and weapons was sufficiently advanced, the physiological advantage that the Neanderthals genetically had, disappeared. Homo Sapiens Sapiens could thrive just as well through winter.

At that point, Homo Sapiens Sapiens from Africa could be as successful as the Neanderthals through the freezing wastelands of Europe. OK.

But the Homo SS outbred the Neanderthals, so they became genetically more successful. How do I explain that?

Simple. However, the explanation involves the exponential function, the same function found all over, and that the mathematician Rudin called “the most important function in mathematics”. The exponential also explains the plutocratic phenomenon, and that is why it’s so dangerous. The exponential always rules extinction events, that’s why one day a species is all over, like the American Pigeon, or the Tasmanian Tiger, and the next day, it’s gone.

So visualize this. Neanderthals were bigger than Homo SS, just like the Polar Bear is bigger than the Black Bear. Bigness is an adaptation to cold. Southern Europe’s Brown Bears are smaller than those found in Kamchatka, or Alaska (also known as Grizzlies: the Grizzly is an emigrated European Brown Bear!) Bigger makes warmer inside. That’s why the most massive animal that ever was, the Blue Rorqual, at up to 180 tons, is nearly twice the mass of the largest dinosaur (it’s not just that it’s floating, but also that water is cooler than Jurassic air, I hold).

To simplify, let’s use a bit of exaggeration (that’s reasoning by exaggeration, one of my preferred tactic of thought; the one humor exploits, and why joking helps thinking). Let’s assume Neanderthals were twice more massive than Homo SS.

Now let’s consider an habitat where Homo SS and Neanderthal bands roamed. They will tend not to mix, for obvious racist reasons. The racial hatred between Neanderthals and Homo SS has got to have been colossal. People who look too different are not even sexually attracted to each other (and where Neanderthals and Homo SS were in contact in the Middle East, for 50,000 years, there is no evolution of an interbred species, an indirect proof that there was no love lost there!)

The density of human mass is going to be roughly the same all over, because that density depends only upon the resources available (mostly meat on the hoof, and fur in burrows in glaciating conditions).

Thus, there would have been apartheid. But the Homo SS would have been twice more numerous, where they reigned (from my assumption of twice the mass). So now graft on this a catastrophe; a drought, a flood, a very tough winter, a volcanic super disaster, whatever. The climate was highly variable, starting about 40,000 years ago, just when Homo SS appeared. Some have stupidly argued that Neanderthals were too stupid to adapt to this changing circumstances. Like this paralyzing stupidity struck them just when Homo SS were around. My explanation is more subtle.

After a catastrophe in said habitat, say one of these numerous habitat in Europe isolated by glacial mountain ranges, or seas and lakes, most of the human population would be wiped out, Homo SS, just as Neanderthals. There would tend to be always a small remaining population, because the greatest limit on man is man himself: as a population gets wiped out, resources rebound, and life of the survivors tend to get much easier (that’s what happened in Europe after the Black Death of 1348 CE; if nothing else, survivors could ask for higher salaries from their plutocratic masters, and they did).

So say 90% of the population of the habitat was wiped out. As suddenly resources are now not limited, the human population will rebound exponentially. The equation is: N(t) = N(0) exp(Rt). “R” is the “Malthusian” parameter, the rate of growth. Now it’s going to require twice the resources to feed a Neanderthal to sexual maturation (under our outrageously simplifying assumption that Neanderthals are twice the mass). Thus one may assume that R(Homo SS)/R(Neanderthal) is 2. The end result is that the quotient:

Number Homo SS/ Number Neanderthal = A exp(2t). (Where A is the ratio of the populations H SS/Neanderthal after the catastrophe.)

Thus the population of H SS would exponentially grow relative to that of the Neanderthals, resulting in a quick extinction. And in no way this is happening because Homo SS were superior. Just because they were more gracile.

Hence the mystery of the evolution of contemporary man is smoothly explained. Just a bit of math. QED.

Note 1: what of the mentally deliquescent and racist article in the Proceedings of the Royal Society? First, they sank so low as to“using orbit size as a proxy, that Neanderthals had larger visual systems than contemporary AMH [Anatomically Modern Humans]“. That’s about as intelligent as saying that, because special forces use night vision goggles, they have got to have bigger visual systems.

The main woman author also found the same physiological feature, bigger eyes, in the past, about people presently living at high latitude. She contentedly asserted that, because light levels are lower in the north, people living in the north (40,000 years at least for Homo SS) have bigger eyes. Amusingly, she did not draw, in that case the conclusion that Norwegians and the English are therefore more stupid. Somehow, though, in her lack of smarts, she applies that controversial reasoning to Neanderthals. Does she have giant eyes?

Seriously the Oxford study rests on a central fact that contradicts one of established facts about Neanderthals. Indeed it claims Neanderthals’ brains were not any larger than Homo SS.

***

Note 2; what catastrophes am I talking about? Well the climate fluctuated wildly, to start with. Second, A Campanian ignimbritevolcanic super-eruption around 40,000 years ago, followed by a second one a few thousand years later, certainly crashed Neanderthal populations (based on logic, and evidence fromMezmaiskaya cave in the Caucasus. Mitochondrial DNA analysis of a specimen there is C14 dated 29,000 years BP, one of the latest living pure Neanderthals). After such a catastrophe, the exponential rebounds of populations would have advantaged Homo SS, as explained above.

***

Note 3: OK, I exaggerated with the mass ratio. (Mathematicians often do this, considering an exaggerated case to understand the mean, through the tails.) But the real mass ratio would be aggravated because, Neanderthal was built in such a way, relative to gracile Homo SS, that they consumed more calories per day (some paleontologists have come up with 300). So there is no doubt that the effect above will play a role, even if the mass ratios were not as bad. Notice the mechanism above would tend to extinguish the Neanderthal traits that were most characteristic of the subspecies.

***

Note 4: A preferred trick of Neanderthals’ haters is to exhibitArchaic Neanderthals‘skulls, and compare them to those of modern men. The skull of an Archaic Neanderthal of 400,000 years ago should not be compared to a modern human, less than 40,000 year old! All the more since Neanderthals’ brain size augmented faster than the brain size of Homo Sapiens Sapiens.

***

Note 5: Part of the mechanism above generalizes for other species in competition. It provides with a disappearance mechanism after ecological turbulence, according to species’ ecological footprint.

oooOOOooo

So hope that others shared my pleasure at reading the essay.

Going to close with another quotation from Mr. Albert Einstein: “As far as the laws of mathematics refer to reality, they are not certain, and as far as they are certain, they do not refer to reality.”

What on Earth to do?

Prediction is very difficult, especially if it involves the future. Niels Bohr

I have seen a number of versions of this quotation from Niels Bohr but no matter the inference is clear.  My way of putting it is that the future has a habit of observing the law of unintended consequences!

This gentle immersion into today’s muse is on the back of two events.  The first was the reading of Guy McPherson’s book, Walking Away from Empire, that I reviewed last week.  The second was watching a fascinating presentation about reversing climate change.

Just stay with Guy McPherson for a moment longer.  He is of the very firm opinion that we face imminent environmental collapse and the collapse of the industrial economy.  His bet is that the environment is already in the grip of ten feedback loops that guarantee making the environment unsustainable for the majority of species on this planet within a couple of decades.  If you want more then take a mouse click across the Guy’s blog Nature Bats Last.

So, given that one embraces this prediction, free of the clouds of delusion that it couldn’t possibly come to that, then what?  (I’m assuming that you have the basic motivation to get out of bed in the morning!)

The natural response is what on earth to do?

That’s where Allan Savory comes in!

WikiPedia introduces him as follows:

OLYMPUS DIGITAL CAMERA

(Clifford) Allan Redin Savory (born September 15, 1935) is a Zimbabwean biologist, farmer, soldier, exile, environmentalist, and winner of the 2003 Banksia International Award and the 2010 Buckminster Fuller Challenge. He is the originator of holistic management.

Savory had begun working on the ancient problem of land degradation (desertification) in 1955 in Northern Rhodesia, where he served in the Colonial Service as Provincial Game Officer, Northern and Luapula Provinces. He subsequently continued this work in Southern Rhodesia first as a research officer in the Game Department, then as an independent scientist and international consultant. When in exile, Savory worked from the Cayman Islands into the Americas introducing his new discoveries about both the cause of desertification and how to reverse it using increased numbers of livestock.

He subsequently wrote up this work in the book Holistic Management: A New Decision Making Framework, written with his wife Jody Butterfield and published by Island Press (1989; 1999 2nd edition).

In 1992, he co-founded the Africa Center for Holistic Management with his wife Jody Butterfield and, in 2009, the Savory Institute, headquartered in Boulder, Colorado, which he currently heads. The Savory Institute works globally with individuals, government agencies, NGOs, and corporations to restore the vast grasslands of the world through the teaching and practice of holistic management and decision making.

The institute’s consulting and training activities are turning deserts into thriving grasslands, restoring biodiversity, bringing streams, rivers, and water sources back to life, combating poverty and hunger, and increasing sustainable food production, all mitigating global climate change through carbon sequestration. In 2010, Savory and the Africa Center for Holistic Management won The Buckminster Fuller Challenge.

In a 2012 address to the International Union for Conservation of Nature World Conservation Congress, on the urgent need to bring agriculture and conservation back together, Prince Charles lauded Savory’s nature based approach.

OK, enough from me. Watch Allan Savory’s fascinating and potentially life-saving idea, as presented to the TED2013 conference.

Walking Away from Empire; a book review

“Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth.” Arthur Conan Doyle.

Ten days ago, I finished reading the book Walking Away from Empire: A Personal Journey. It had been sent to me by the author.

Let me explain how this came about.

A few weeks ago, I published an item under the title of Doggedly seeking the truth.  I included the video “The Twin Sides of the Fossil-Fuel Coin: Developing Durable Living Arrangements in Light of Climate Change and Energy Decline.“  That video was a presentation by Prof. Guy McPherson.

Subsequently, during an exchange of emails with Prof. McPherson there was an offer to receive a free copy of his book, Walking Away from Empire: A Personal Journey.  Naturally, I accepted.

Having finished reading the book it seemed only fair to write a review.

So far, so good!

I tried to marshal my thoughts for well over a week.   Couldn’t get started.  Strange, because when immersed in the book the messages were crystal clear.

Why the struggle to embrace Guy McPherson’s messages?  Then in a moment of insight I realised that I was struggling to understand why I was struggling!

walkingaway
Published by PublishAmerica, LLLP

Because the blunt truth of the matter is that this book spells out the bleedin’ obvious.  Humanity is between a rock and a hard place!

Look no further than the very first paragraph of the first chapter, Reason,:

At this late juncture in the era of industry, it seems safe to assume we face one of two futures. If we continue to burn fossil fuels, we face imminent environmental collapse. If we cease burning fossil fuels, the industrial economy will collapse. Industrial humans express these futures as a choice between your money or your life, and tell you that, without money, life isn’t worth living. As should be clear by now, industrial humans — or at least our “leaders” — have chosen not door number one (environmental collapse) and not door number two (economic collapse), but both of the above.

Sandy Krolick of Transition Voice wrote a review of Guy McPherson’s book in September, 2011.  His last sentence was, “This is a book you will not put down; and having read it, you’ll no longer be able to ignore its conclusions.”

Again, what Sandy Krolick writes is perfectly correct. No argument.  Yet …. something about that sentence from Sandy doesn’t speak to me.  That struggle again.

Then I got it!

Let me go straight to page 177 of Prof. McPherson’s book and quote this:

It’s no longer just the living planet we should be concerned about. It’s us. The moral question, then: What are you going to do about it?

Then one paragraph later, come this:

There is simply no feeding the hollow spot in my gut and my psyche, as there was when I replaced my invisible, omnipotent friend in the sky with reason. Instead of abandoning the mirage of eternal life, I’m abandoning the mirage of globalization. Instead of giving up an everloving god, I’m giving up a comfortable life spent with my best friend. I’m taking yet another step in the path from make-believe to reality. And, as we all know, reality is a harsh, dispassionate mistress who doesn’t give a damn about the emptiness in my fragile little psyche. Fortunately, I still have the amusing memories of the absurdity of my former life, in which I believed I was saving the world by conducting and publishing mundane research and teaching irrelevant concepts to a largely disinterested audience.

I found the first step to be the most difficult. Simply recognizing the industrial economy as an omnicidal imperial beast forced me to cross a threshold most people find far too formidable to attempt.

Just reflect on those key words, “a threshold most people find far too formidable to attempt.”

Keep those words in mind as I quote the next paragraph from the book.

We’ve never been here as a species, much less as individuals. And every cultural message tells us we’re wrong, that the industrial age will last forever, that justice and goodness will prevail over every enemy (i.e., terrorist), that progress is a one-way street to industrial nirvana, that the harbinger of hope will keep the oil coming and the cars running and the planes flying so we can all soak up the sun on a sandy beach any time we need a break from our tumultuous lives in the cube farms of empire.

This, then, was the result of reading the book.  The realisation of the reality of our existence.  The immensity of the truth of where mankind is.  The here and NOW!

Sorry, let me amend those last sentences.  My realisation of the reality of my existence.  The immensity of the truth of where I am.  My here and NOW!

No wonder I struggled.

So not much of a book review, more a review of yours truly!  That is the power of this book.  Sandy Krolick was right; “This is a book you will not put down; and having read it, you’ll no longer be able to ignore its conclusions.”

Be warned.  When you read this book brace yourself for what you see staring out of the mirror back at you. There will be no room left for delusion.

As Carl Sagan said, “It is far  better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring.“

Carl Sagan

How very precious, vulnerable and fragile is this precious place we call home.

Today’s consciousness perambulation is the fault of Mr. P., as I like to call him. I refer to Pendantry as he is on his blog, Wibble.

You see on Sunday he added a comment to my post Just a small, white dot! that included the beautiful and awe-inspiring film made by the late Carl Sagan called Pale Blue Dot.

carl-sagan

Like millions of others, I came to admire Carl Sagan through watching the fabulous, the truly fabulous, television series Cosmos: A Personal Voyage. (NB. All the episodes are on YouTube, Episode One is at the end of this Post, Ed.)  Here’s how WikiPedia opens their reference to Carl.

Carl Edward Sagan (November 9, 1934 – December 20, 1996) was an American astronomer, astrophysicist, cosmologist, author, science popularizer and science communicator in astronomy and natural sciences. He spent most of his career as a professor of astronomy at Cornell University where he directed the Laboratory for Planetary Studies.

He published more than 600 scientific papers and articles and was author, co-author or editor of more than 20 books. He advocated scientifically skeptical inquiry and the scientific method, pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI).

Sagan is known for his popular science books and for the award-winning 1980 television series Cosmos: A Personal Voyage, which he narrated and co-wrote.  The book Cosmos was published to accompany the series. Sagan wrote the novel Contact, the basis for a 1997 film of the same name.

He died far too young and was a tragic loss to humanity.  The Carl Sagan web portal is here.

That 3:30 minute video Pale Blue Dot has, likewise, been seen by millions.  If you or someone you know hasn’t seen it, then you must pause now …

It’s practically impossible to watch that video and not embrace the central message from Mr. Sagan.  Here’s the transcript:

Our home from 6 billion kilometres. A very tiny dot against the vastness of space.

From this distant vantage point, the Earth might not seem of any particular interest. But for us, it’s different.

Consider again that dot. That’s here. That’s home. That’s us.

On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.

The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena.

Think of the rivers of blood spilled by all those generals and emperors so that in glory and triumph they could become the momentary masters of a fraction of a dot.

Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.

Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity – in all this vastness – there is no hint that help will come from elsewhere to save us from ourselves.

The Earth is the only world known, so far, to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment, the Earth is where we make our stand.

It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another and to preserve and cherish the pale blue dot, the only home we’ve ever known.

Tomorrow, I will stay with the theme of our beautiful planet. Hope you can join me.

Now spoil yourself and watch Episode One of Cosmos.

Just a small, white dot!

Does rather serve to remind us of our place in the scheme of things.

This stunning image was taken by the Cassini-Huygens probe.  Many of the images taken by NASA are available for download from the DVIDS website, which is where this one was found. (But also do visit the Ciclops website.)

The title of the photograph is:

A View of Earth from Saturn

A View of Earth from Saturn: Image of the Day

Although the Earth Observatory typically reserves ”Image of the Day” space for publishing data and images acquired by Earth-observing satellites, we are sometimes so enthralled by the spectacular images acquired by spacecraft observing other parts of the solar system that we want to share these ‘otherworldy’ views with our visitors. And if you are looking for remotely sensed images of the Earth, this view is the most remotely sensed image we have ever published!

This beautiful image of Saturn and its rings looks more like an artist’s creation than a real image, but in fact, the image is a composite (layered image) made from 165 images taken by the wide-angle camera on the Cassini spacecraft over nearly three hours on September 15, 2006.

Scientists created the color in the image by digitally compositing ultraviolet, infrared, and clear-filter images and then adjusting the final image to resemble natural color. (A clear filter is one that allows in all the wavelengths of light the sensor is capable of detecting.) The bottom image [the one above. Ed.] is a closeup view of the upper left quadrant of the rings, through which Earth is visible in the far, far distance.

On this day, Saturn interceded between the Sun and Cassini, shielding Cassini from the Sun’s glare. As the spacecraft lingered in Saturn’s shadow, it viewed the planet’s rings as never before, revealing previously unknown faint rings and even glimpsing its home world. Seen from more than a billion kilometers (almost a billion miles) away, through the ice and dust particles of Saturn’s rings, Earth appears as a tiny, bright dot to the left and slightly behind Saturn.

Although it might appear that Earth is located within Saturn’s outermost rings, that positioning is just an illusion created by the enormous distance between Cassini and Earth. When Cassini took this image, the spacecraft was looking back at Saturn from a distance of about 2.2.million kilometers (about 1.3 million miles). The Sun was millions of additional miles beyond, hidden behind Saturn. On September 15, Earth’s orbit had brought our home planet to a location slightly behind and to the left of the Sun from Cassini’s perspective. The Website of the Cassini Imaging Central Laboratory for Operations (CICLOPS) provides more detailed information about this image. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency, and the Italian Space Agency.

Trying to find that faint image of Planet Earth in the above photograph is a challenge, even for those with much younger eyes than mine.

However, with a little bit of jiggery-pokery I was able to crop and enlarge the photograph, see below:

saturn

Planet Earth is in the ’10 o’clock’ position in the photograph, about half-way from the centre of the enlarged segment towards the top-left corner of the picture, just outside the outer white ring.

That’s us. All that we have ever been. All that we ever will be. Just that small white dot.

Reflections on Integrity.

Going back to basics.

Many will know the origins of this blog; a chance comment by Jon Lavin back in England in early 2007 that dogs were integrous,  (a score of 210 as defined by Dr David Hawkins).

Way back in 2009, I wrote this:

“There is nothing to fear except the persistent refusal to find out the truth, the persistent refusal to analyse the causes of happenings.” Dorothy Thompson.

When I started Learning from Dogs I was initially rather vague but knew that the Blog should reflect the growing need for greater integrity and mindfulness in our planetary civilisation.  Here are some early musings,

Show that integrity delivers better results … integrity doesn’t require force … networking power of a group … demonstrate the power of intention … cut through the power of propaganda and media distortion …

Promulgate the idea that integrity is the glue that holds a just society together … urgent need as society under huge pressures …. want a decent world for my grandchildren … for all our grandchildren …. feels like the 11th hour….

But as the initial, rather hesitant, start to the Blog settled into a reliable, daily posting, and as the minuscule number of readers steadily grew to the present level of many hundreds each day, the clarity of the purpose of Learning from Dogs also improved.

Because, while it may sound a tad grandiose and pompous, if society doesn’t eschew the games, half-truths and selfish attitudes of the last, say, 30 years or more, then civilisation, as we know it, could be under threat.

Or, possibly, it’s more accurate to say that our civilisation is under threat and the time left to change our ways, to embrace those qualities of integrity, truth and consciousness for the very planet we all live on, is running out.

“Time left to change our ways is running out.”

So what’s rattled my cage, so to speak, that prompted today’s reflection?  I’ll tell you! (You knew I was going to anyway, didn’t you!)

I’m drafting these thoughts around noon Pacific Standard Time on Sunday, 17th.  At the same time, tens of thousands of ordinary good folk (40,000 plus at the latest estimate) are gathering by the Washington Monument ready to march past the White House demanding that President Obama block the Keystone XL pipeline and move forward toward climate action.

Do I trust the US Government to take this action?  On balance, no!  That hurts me terribly to write that. I really want to trust and believe what the President of my new home country says.

State of the Union speech 2013. AP photo.
State of the Union speech 2013. AP photo.

Here’s a snippet of what the President did say in his State of the Union speech on February 12th.

Now, it’s true that no single event makes a trend. But the fact is, the 12 hottest years on record have all come in the last 15. Heat waves, droughts, wildfires, floods, all are now more frequent and more intense.

We can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence. Or we can choose to believe in the overwhelming judgment of science and act before it’s too late.

A frank admission that the climate is changing in dramatic ways; the overwhelming judgment of science – fantastic!

The evidence that burning carbon-based fuels (coal, oil, gas) is the primary cause of today’s high CO2 levels is overwhelming. As a recent BBC radio programme reveals (being featured tomorrow) huge climate changes going back millions of years are a natural part of Earth’s history.  However, as one of the scientists explains at the end of that radio programme, the present CO2 level, 395.55 ppm as of January, is now way above the safe, stable limit for the majority of life species on the planet.

But say you are reading this and are not yet convinced?

Let me borrow an old pilot’s saying from the world of aviation: If there’s any doubt, there’s no doubt!

That embracing, cautious attitude is part of the reason why commercial air transport is among the most safest forms of transport.  If you had the slightest doubt about the safety of a flight, you wouldn’t board the aircraft.

If you had the slightest doubt about the future for civilisation on this planet likewise you would do something!  Remember, that dry word civilisation means family, children, grandchildren, friends and loved ones.  The last thing you would do is to carry on as before!

Which is where my lack of trust of leaders comes from!

Back to that State of the Union speech.  Just 210 words after the spoken words “act before it’s too late”  (I counted them!) Pres. Obama says, “That’s why my administration will keep cutting red tape and speeding up new oil and gas permits.”

Here’s the relevant section:

I will direct my cabinet to come up with executive actions we can take, now and in the future, to reduce pollution, prepare our communities for the consequences of climate change, and speed the transition to more sustainable sources of energy.

Now, four years ago, other countries dominated the clean-energy market and the jobs that came with it. And we’ve begun to change that. Last year, wind energy added nearly half of all new power capacity in America. So let’s generate even more. Solar energy gets cheaper by the year. Let’s drive down costs even further. As long as countries like China keep going all-in on clean energy, so must we.

Now, in the meantime, the natural gas boom has led to cleaner power and greater energy independence. We need to encourage that. That’s why my administration will keep cutting red tape and speeding up new oil and gas permits.

We don’t require any more oil to be used.  We are already using a staggering amount of it. Let me refer you to an essay on Nature Bats Last called Math. The scary kind, not the fuzzy kind.  Prof. McPherson wrote:

I performed a little rudimentary math last week. A little because even a little pushes my limit for math, these days. And rudimentary for the same reason. The outcome was staggering: We’re using oil at the rate of 5,500 cubic feet per second (cfs).

“5,500 cubic feet per second” Don’t know about you but I have some trouble in visualising that flow rate.  Try this from later in the essay:

Here’s another shot of perspective: We burn a cubic mile of crude oil every year. The Empire State Building, the world’s ninth-tallest building, towers above New York at 1,250 feet. The world’s tallest building, Taipei 101, is 1,667 feet from ground to tip.

Put those buildings together, end to end, and you have one side of a cube. Do it again, and you have the second side. Once more, but this time straight up, and you have one big cube. Filling that cube with oil takes nearly 200 billion gallons … which is about one-sixth the size of the cube of oil we’re burning every year.

Burning a cubic mile every year!  Yes, Mr. President, more oil permits is a wonderful way of taking action before it’s too late!

cubic mile

So let’s see what transpires?  Let’s see if integrity is given the highest political focus.  As in “adherence to moral and ethical principles; soundness of moral character; honesty.”  Because if there’s ever been a time when all of us, from every spectrum of society need honesty about what we are doing to the planet, it’s now!

As the tag on the home page of this blog says, “Dogs are integrous animals.  We have much to learn from them.“

Do you or I really know who we are?

The strangeness of this species Homo sapiens.

My writings of the previous three days have explored the nature of man.  The many ways that we struggle to understand so many issues in our lives. In particular the biggest issue of them all since we abandoned the life of the hunter-gatherer.  Our very survival.

It would be so easy to beat oneself up.  To stare in the mirror and despair at all the unfinished ideas that one has about being ‘sustainable’ shortly before jumping on one’s shiny new tractor, yet another symbol of our industrial civilisation.  The hypocrisy, the double standards!

New tractor being delivered last December.
New tractor delivered last December.

But the mistake in any attempt at self-awareness is the assumption that you know who you are!  Therein lays the problem.!

Marcus Peter Francis du Sautoy is a very smart person.  This is how WikiPedia describes him.

sautoy
Prof. Marcus Sautoy

Marcus Peter Francis du Sautoy, OBE (born in London, 26 August 1965)[3] is the Simonyi Professor for the Public Understanding of Science and a Professor of Mathematics at the University of Oxford. Formerly a Fellow of All Souls College, and Wadham College, he is now a Fellow of New College. He is President of the Mathematical Association.

Prof. Sautoy came to the realisation that the thoughts that make us feel as though we know ourselves are easy to experience.  But where do those thoughts come from? Marcus Sautoy acknowledged that they are notoriously difficult to explain.

So, in order to find out where they come from Marcus subjects himself to a series of probing experiments.  With the help of a hammer-wielding scientist, Jennifer Aniston and a general anaesthetic, Professor Marcus du Sautoy goes in search of answers to one of science’s greatest mysteries: how do we know who we are? ,

He learns at what age our self-awareness emerges and whether other species share this trait.

Next, he has his mind scrambled by a cutting-edge experiment in anaesthesia. Having survived that ordeal, Marcus is given an out-of-body experience in a bid to locate his true self. And in Hollywood, he learns how celebrities are helping scientists understand the microscopic activities of our brain.

Finally, he takes part in a mind-reading experiment that both helps explain and radically alters his understanding of who he is.

All of this is covered in a fabulously interesting episode from Horizon, the excellent and long-running  BBC TV science and philosophy series.  Thankfully, it made its way onto YouTube.

It is just under an hour long but I promise you it will capture you from the very first moment.

Enjoy.  Even if you end up realising, as I did, what a strange person you are!

As Confucius reportedly wrote: Real knowledge is to know the extent of one’s ignorance.
