The unconscious

A Biological Basis for the Unconscious? Surely not?

Ten days ago or thereabouts, I saw a piece on Big Think about the unconscious.  The title of the piece was as the sub-heading: A Biological Basis for the Unconscious?  I was intrigued, to say the least, and wanted to write about that on Learning from Dogs.

The article started thus:

What’s the Big Idea?

Eric Richard Kandel

Today, the question of how people make decisions is an animated and essential one, capturing the attention of everyone from neuroscientists to lawyers to artists. In 1956, there was one person in all of New York known for his work on the brain: Harry Grundfest. An aspiring psychiatrist who was born in Austria in the 1930’s, Eric Kandel took an elective in brain science during medical school and found himself studying alongside Grudfest at Columbia University.

“What is it you want to study?” Grundfest asked Kandel. “I want to know where the id, the ego, and the super-ego are located in the brain,” Kandel replied. Grundfest looked at him as if he was crazy. “I haven’t got the foggiest notion whether these constructs exist,” he said. “But the way to approach the brain is to study it one cell at a time. Why don’t you study how the cells work?”

Now it would be improper to republish the whole article, not having permission to so do, and I thoroughly recommend you going to the article here and reading it completely from the Big Think website.

But there are a number of interesting videos on YouTube and the one I have selected is a great example of Kandel’s power of mind.  As the short description of the video reveals, “A Conversation With Nobel Laureate Eric Kandel, Who Continues to Look Forward at 80.”

Having the dog of a day!

Maybe there’s a new twist to that rather derogatory phrase!

For the life of me, I can’t remember how this story came to my ‘in-box’ but most likely it was from my Big Think subscription.  But I do know that the story has spread like wild-fire (poor choice of simile for Arizona!) and not without good reason.

Here’s how it was promoted on Science Daily,

Benefits of Taking Your Dog to Work May Not Be Far-Fetched

Man’s best friend may make a positive difference in the workplace by reducing stress and making the job more satisfying for other employees, according to a Virginia Commonwealth University study.

Stress is a major contributor to employee absenteeism, morale and burnout and results in significant loss of productivity and resources. But a preliminary study, published in the March issue of the International Journal of Workplace Health Management, found that dogs in the workplace may buffer the impact of stress during the workday for their owners and make the job more satisfying for those with whom they come into contact.

The VCU researchers compared employees who bring their dogs to work, employees who do not bring their dogs to work and employees without pets in the areas of stress, job satisfaction, organizational commitment and support.

Then over at the New York Daily News, it was presented thus,

Bring your dog to work to lower stress; Companies that allow pooches have happier workers

Amazon, Ben & Jerry’s and Zynga all have pup-friendly policies

A new study supports the stress-reducing benefits of bringing your pooch to work — to play with, look at, and pet while working.

According to a Virginia Commonwealth University study, having a dog at work not only reduces the owners’ stress level but also increased the level of job satisfaction for other employees as well. The study, announced Thursday, was published in the International Journal of Workplace Health Management.

“Dogs in the workplace can make a positive difference,” said head researcher Randolph T. Barker. “The differences in perceived stress between days the dog was present and absent were significant. The employees as a whole had higher job satisfaction than industry norms.”

Here’s a great example.  The photograph below,

One hand for the desk and one for the dog!

comes from the website of Interior Design Hound (seriously) where the by-line is Good Design with a Canine Twist! (No, I’m not making it up!)

Anyway, back to that NY Daily News item,

The study took place at Replacements Ltd, a service-manufacturing-retail company located in North Carolina, which employs approximately 550 people. The company has a dog friendly policy, similar to other  companies such as Amazon, Ben & Jerry’s and Zynga, according to CBS News, with around 20 to 30 dogs romping through the office every day. The study took place over a period of one work week, and subjects completing both surveys and saliva samples to measure stress levels.

According to The Humane Society of the United States, there are numerous benefits to having dogs at work, including improved staff morale, worker productivity, and camaraderie among employees.

Numerous studies have shown that having a pet is a good investment for your health. One study found that having a pet lowered your risk factors for heart disease, and another found that dogs encourage more consistent walking and exercise.

Seems pretty obvious to me.

Another tough day at the office!

Mind you, going back to the metaphorical ‘having a dog of a day‘ here’s one woman who probably wished she hadn’t got out of bed that morning,

Woman has a dog of a day in court

Sydney – If you have a phobia about dogs and hurt yourself running away from one, is it your own fault or should the owner of the dog pay compensation?

An Australian judge on Wednesday ruled against a woman who had put that case to him and ordered her to pay substantial legal costs.

Mileva Novakovic took her brother, Michael Stekovic, and his wife to the New South Wales Court of Appeal to try to overturn a lower court verdict that found they were not liable for injuries she sustained at his house in 2008.

Novakovic slipped and fell in a panic over finding a dog in their lounge room. She admitted to a fear of dogs and said she was compelled to run despite Cougar, a mastiff, showing no aggression towards her.

 

Very scary!

Turning corners, en route to Plan B.

Nothing stays the same for very long!

I wanted to call this post Change out of hope but that title was used on March 17th so opted for Turning corners instead!

Either way, this Post is prompted by a recent item published on the Earth Policy Institute website.  While Lester Brown’s book World on the Edge is a tough read, Lester is President of the Earth Policy Institute, it’s all too easy to think that the future for humanity is wall-to-wall gloom.  So here’s the article that was recently published, reproduced here under the copyright terms of the Earth Policy Institute.

Hope turning on the wind!

Wind Tops 10 Percent Share of Electricity in Five U.S. States

by J. Matthew Roney

A new picture is emerging in the U.S. power sector. In 2007, electricity generation from coal peaked, dropping by close to 4 percent annually between 2007 and 2011. Over the same time period, nuclear generation fell slightly, while natural gas-fired electricity grew by some 3 percent annually and hydropower by 7 percent. Meanwhile, wind-generated electricity grew by a whopping 36 percent each year. Multiple factors underlie this nascent shift in U.S. electricity production, including the global recession, increasing energy efficiency, and more economically recoverable domestic natural gas. But ultimately it is the increasing attractiveness of wind as an energy source that will drive it into prominence.

Wind power accounted for just 2.9 percent of total electricity generation in the United States in 2011. In five U.S. states, however, 10 percent or more of electricity generation came from wind. South Dakota leads the states, with wind power making up 22 percent of its electricity generation in 2011, up from 14 percent in 2010. In 2011, Iowa generated 19 percent of its electricity with wind energy. And in North Dakota, wind’s share was 15 percent.

The two most populous U.S. states are also harnessing more of their wind resources. While adding more than 900 megawatts of new wind farms in 2011 to its existing 3,000-megawatt wind capacity, California was able to increase its wind electricity share from 3 to 4 percent. Texas has the most wind installations of all the states, with 10,400 megawatts. In fact, if Texas were a country, it would rank sixth in the world for total wind capacity. Figures from the Electric Reliability Council of Texas (ERCOT), the independent service operator that delivers 85 percent of the state’s electricity, show that wind’s share of electricity in the ERCOT region jumped from 2.9 percent in 2007 to 8.5 percent in 2011.

Even though the cost of generating electricity from the wind has fallen substantially, certain policies have been needed to help it compete with the longtime support and lack of full-cost accounting for fossil fuels. Through so-called renewable portfolio standards (RPS), 29 states now require a percentage of utilities’ electricity to come from renewables by a certain date. This includes 8 of the top 10 states in total installed wind power capacity. For example, California’s RPS requires one third of the state’s electricity to come from renewable sources by 2020. But the biggest policy driver of U.S. wind power growth thus far has been the federal production tax credit (PTC) for each kilowatt-hour of electricity a wind turbine generates. When Congress has allowed the PTC to expire, as it is scheduled to do again at the end of 2012, wind installations in the following year have plummeted.

In the short term, extending the PTC will be critical for the U.S. wind industry, which boasts more than 400 turbine component manufacturers and employs some 75,000 people. Ultimately, moving away from the recurring boom-bust threat by establishing a national RPS or a carbon tax would encourage even greater manufacturing growth and wind installations.

In a country where wind resources could power the entire economy, there is still great potential to be realized. Four states in northern Germany have set the mark, with each getting more than 40 percent of their electricity from the wind. Which U.S. state will get there first?

This video is well worth watching as well as going to that link at the end of the essay above.

Lester Brown, Thomas Friedman, and Paul Krugman discuss the need for a carbon tax in order to price carbon emissions at their true cost.

The “Journey to Planet Earth” series continues with a special program, hosted by Matt Damon, which features environmental visionary Lester Brown and author of “Plan B.” This documentary delivers a clear and unflinching message — either confront the realities of climate change or suffer the consequences of lost civilizations and failed political states.

I will see how much material there is available online with regard to that programme hosted by Matt Damon and, maybe, present some of it on Learning from Dogs.

Finally, the picture of the wind turbine at the head of this Post came from a website called www.windgeneratorblog.com.  Fancy a home wind generator?

Nature’s voice.

A republication of a recent Post from Kate of Climate Sight.

Introduction

My apologies for a second republication of another’s Post in two days, but a number of things today (Tuesday) have robbed me of the time I usually have for writing for Learning from Dogs.  So the Post from ClimateSight that I had planned to bring to you on Thursday has been brought forward.

To Kate’s Post on ClimateSight but first a little of Kate’s background,

Kate is a B.Sc. student and aspiring climatologist from the Canadian Prairies.

She became interested in climate science several years ago, and increasingly began to notice the discrepancies between scientific and public knowledge on climate change. She started writing this blog when she was sixteen years old, simply to keep herself sane, but she hopes she’ll be able to spread accurate information far and wide while she does so.

Kate is getting into climate modelling, and presented the results of her first research project at the 2011 AGU Fall Meeting.

I subscribe to ClimateSight and, thus, on the 1st April, I received the following.  I republish it in full with Kate’s written permission.

March Migration Data

In my life outside of climate science, I am an avid fan of birdwatching, and am always eager to connect the two. Today I’m going to share some citizen science data I collected.

Last year, I started taking notes during the spring migration. Every time I saw a species for the first time that year, I made a note of the date. I planned to repeat this process year after year, mainly so I would know when to expect new arrivals at our bird feeders, but also in an attempt to track changes in migration. Of course, this process is imperfect (it simply provides an upper bound for when the species arrives, because it’s unlikely that I witness the very first arrival in the city) but it’s better than nothing.

Like much of the Prairies and American Midwest, we’ve just had our warmest March on record, a whopping 8 C above normal. Additionally, every single bird arrival I recorded in March was earlier than last year, sometimes by over 30 days.

I don’t think this is a coincidence. I haven’t been any more observant than last year – I’ve spent roughly the same amount of time outside in roughly the same places. It also seems unlikely for such a systemic change to be a product of chance, although I would need much more data to figure that out for sure. Also, some birds migrate based on hours of daylight rather than temperature. However, I find it very interesting that, so far, not a single species has been late.

Because I feel compelled to graph everything, I typed all this data into Excel and made a little scatterplot. The mean arrival date was 20.6 days earlier than last year, with a standard deviation of 8.9 days.

Back to me.

What is equally interesting as Kate’s Post above are some of the comments.  Like this one,

Roger

Doesn’t always work…

Here in central Illinois the robins depart in the fall and arrive in the spring; that’s the way it’s always been and that’s the way it should be, right?

Not anymore. Some years recently we’ve seen robins nearly the entire winter, if we can still call it that.

Our Canadian Geese have forgotten how to migrate.

Questions are never stupid!

A powerful guest post from Patrice Ayme on where next for American energy.

Introduction.

I must have spent an age musing over what to call this Post.  Patrice called it simply ‘Energy Question For The USA’ and it’s a highly appropriate question.  But in the end I chose the title ‘Questions are never stupid’ because I was mindful of the well-known saying, “There is no such thing as a stupid question, only a stupid answer!

So the smart question raised by Patrice is not only very highly appropriate for 2012, it’s also a question that just has to have a smart answer.  Because we are on the brink of it being too late to be flirting with stupid answers.  What many scientists are saying, in one form or another, is that if we don’t embrace the journey of moving away from carbon-based sources of energy for society now and find those alternate sustainable sources by the end of this decade then the laws of unintended consequences will kick in with a vengeance.  The end of the decade is eight years away!

Here’s a picture of my grandson who was one-year-old just a week ago.

Trusting his elders!

That picture reminds me of the comment early on in James Hansen’s book, Storms of my Grandchildren, where he writes ‘I did not want my grandchildren, someday in the future, to look back and say, “Opa understood what was happening, but he did not make it clear.

So on to the Guest post from Patrice.  It’s not an easy, quick read but I’ll tell you what it is!  It’s the sort of ‘wake-up’ call this fine Nation and this even finer Planet should be getting from countless politicians and leaders.  So do read it and, even better, add your comments, and wonder why we seem so content on fiddling while Rome burns!

oooOOOooo

Energy Question For The USA

THE AGE OF OIL PRODUCED THE AMERICAN CENTURY. NOW WHAT?

No Vision, No Mission, No Energy

***

Another editorial of Paul Krugman firing volleys at republican “paranoia” for accusing Obama of driving up oil prices. As he observes in “Paranoia Strikes Deeper“: …“the president of the United States doesn’t control gasoline prices, or even have much influence over those prices. Oil prices are set in a world market, and America, which accounts for only about a tenth of world production, can’t move those prices much. Indeed, the recent rise in gas prices has taken place despite rising U.S. oil production and falling imports.”

American households tend to borrow as much as they can. Thus, when oil prices increase markedly, Americans have to cut in crucial budgets, such as house payments. I said at the time that it would lead to a peak in housing prices, and it did.

Why such a drastic influence of oil prices on the economy of the USA? Because Americans, except in a few places such as New York, commute by private car to work. So Americans have to feed the car, if they want to feed themselves.

It was not this way a century ago, or so. At the time public transportation systems using electric tramways and trains were found all over, even in Los Angeles. Car companies put an end to that outrage in the late fifties by buying, and then destroying, all the public transportation system they could put their greedy hands on.  Fossil fuel plutocrats were delighted.

But let’s set aside Krugman’s fake indignation. He is smart enough to know that Romney will do what Romney needs to do to win the Obama, I mean, the election. Waxing lyrical about Romney doing as Obama, does not beat going lyrical about sunrise.

Gasoline prices in the USA are way down in real dollars to what they used to be, decades ago. And so is the gas tax. This means that, far from adapting to the gathering multiply-pronged world ecological and energy crisis, the USA has gone the other way, denying there is any crisis. “What? Me worry?” That’s got to be anti-American indeed.  No, real blooded Americans are all into strip searches and the death panel at the White House.

In Europe, gas prices are more than twice that of the USA, thanks to heavy taxes (stations in France have sported two euros a liter, that is 8 euros per gallon, or more than $10.50). [UK unleaded petrol price, as of today, is the equivalent of $8.70 per gallon, Ed.]

This means that far from being down and out, Europe is efficient enough to operate at that high price level. It also means that Europe is much more motivated than the USA to get much more efficient. In other words, high gasoline prices in Europe are a safety margin. The high prices force the European free market to adapt to a situation that the free market of the USA will encounter someday. Adaptation takes decades: new energies take on the average, historically speaking, 50 years to become dominant. Same, one would guess, for energy efficiencies.

Basically, if oil prices doubled from here, gasoline prices would double in the USA. Whereas, even if the Europeans decided to keep the same high taxes, gasoline prices would only augment by 50%. And, in the much more efficient European economy, with plenty of public electric transportation available, the noxious effects on the European economy would be much less than one would expect from a 50% oil price rise.

The world gets 55 × 1018 joules of useful energy from 475 × 1018 joules of primary energy produced by fossil fuels, biomass and nuclear power plants. That tremendous inefficiency (less than 13%!)  needs to be corrected. It will be, if, and only if, prices are kept high. Thus energy taxes are necessary to adapt to the looming penury.

Why looming penury? Because the reserves of other fossil fuels may have been vastly overestimated (by a factor of 5 in the case of coal). Various fossil fuel lobbies have an interest to over-estimate the reserves (because it keeps the world addicted, as they present their industry as a long range solution, which it is not).

Looking at the raw production numbers, as exhibited below in the graphs, paints a completely different story: production from existing fields is going down dramatically (at 5% rate, per year).  In other words we are in the treachorous waters between the catastrophe of CO2 poisoning and the disaster of running out of energy to burn.

The unavoidable rise of fuel prices will be less grave in Europe than in the USA, because many Europeans would opt for the available electric-based public transportation system (the combination of much more efficient electric motors and central generation is much more efficient than distributing oil to put in SUVs all over, as done in the USA; SUVs, because there are too many holes in the asphalt. A problem partly related to high oil prices!).

Yet, the increase of the cost of imported oil corresponds exactly to the Italian deficit ($55 billion). Although that deficit increase had many causes, oil price increase was by far the most important. And the same for other Southern European countries. So the rise of oil prices was the barrel that broke the back of European debt.

In the USA, ten out of 11 post WWII recessions were followed by oil price spikes. Why are American minds so closed up to the looming strangulation of their economy by oil? Because the fossil fuel plutocracy is on a rampage in the USA. It uses a red hot propaganda to persuade the vast American public of undifferentiated sheep that there is no CO2 ecological crisis, and no energy crisis. (Although the latest polls indicate that two thirds of the public, in a splendid turn-around, believe that there is indeed a man-made climate change crisis; never mind that the New York Times had the latest tornado rampage, with 40 dead, presented as discreetly as possible.)

Why are the fossil plutocrats hysterical? Well we are past Peak Cheap Oil. Moreover, the “majors“, the world’s largest oil companies, have been pushed out of more and more countries, and replaced by national oil companies. Desperate, the majors have gone for riskier and riskier drilling in the deep ocean. Now Chevron, and Transocean, after a 4-day leak off Brazil, see prosecutors asking for lengthy prison sentences and enormous fines.

Most of these oil companies are American, so they have pushed forfracking (destroying the underground with poisons to extract fossil fuels). Superficially, it works: USA imports of fossil fuels went quickly from 60% down to 40%.

However, that did not make a dent in the world price situation, because the demand keeps rising, but the world, overall, is PAST PEAK OIL (as I have long argued and the Nature article alluded to below confirmed, using the obvious argument found in the graphs).

So, basically, American fracking finances Chinese oil consumption. Here are some graphs extracted from Nature and the USA government:

When the horrid sun of diminishing resources rises over the parched American oil desert, while fracking reveals itself to be an unfathomable catastrophe, the howling is going to be very great, and one more reason for a depression will blossom.

Much of the USA’s superiority, in the last 150 years, has come from abundant and cheap oil. First in the North-East, then down to Oklahoma, Texas, Colorado, California. Compare with Western Europe, which had basically no oil.

Oil was not just a question of cheap, convenient energy. Oil has, short of nuclear energy, the highest energy density of any material (OK, nuclear energy is millions of time more energy dense).

Oil gave the USA enormous diplomatic and conspiratorial leverage. American oil plutocrats helped Lenin and Stalin develop their colossal fields in the Caucasus and Caspian. One of those plutocrats, Harriman, son of a railroad magnate, and brother of another Harriman, was one of the main operators of the democratic party. Let alone banker to Hitler. He was decorated both by Stalin, and by Hitler. He then went on as U.S. ambassador to major European capitals, and stayed one the main operators of the government of the USA for decades. “Democrats” have long been impure.

Interestingly, I searched the Internet for a document mentioning Harriman’s Stalino-Hitlerian decorations, but could not find it (I have seen the pictures in the past). All I could read is how much Harriman resisted Stalin each time they met, and that was all the time (a total lie that Harriman resisted Hitler, or Stalin: Harriman was an accomplice of Stalin, and helped give him half of Europe, in exchange for manganese and other stuff. But now Internet agents are obviously paid to reconstruct a truth where American plutocrats look good,  knights in shining armor, fighting Stalin or Hitler, each time they met for tea, dinner, lunch, breakfast, and interminable conferences, for years on end, decade after decade).

A famous example of the clout oil provided the USA with: Texaco fueled Hitler’s conquest of the Spanish republic (this one is hard to hide, because the U.S. Congress slapped Texaco with a symbolic fine, well after the deed was done). That used to amuse Hitler a lot (Hitler gave elaborated reasons to his worried supporters for being in bed with American plutocrats; as the Nazi Party was officially socialist, and anti-plutocratic, that awkward situation may have led him to declare war to the USA on December 11, 1941, to ward off the German generals’ argument that he was just a little corporal in above his head).

Another example: Mussolini was hanged from an American gas station in Milan. Italian communists hanged him from his sponsors’ works.

The fueling of the fascists by American fossil fuel companies helped bring the American Century to the world in general, and Europe in particular. Without Stalin and American plutocratic oil, Hitler’s Panzers could not have moved in 1939 or 1940.

The dignified Elie Wiesel, instead of crying crocodiles tears, wondering how such a thing as Auschwitz was possible, should ask how and why the Nazi extermination machine was fuelled by American plutocrats, and how come he, himself, never talks about that.

Wiesel got the Nobel Peace Prize, just as Jimmy Carter (who launched the American attack on Afghanistan). Was it for disinformation? (And how come waging war in Afghanistan is a big plus for the Peace Prize? Is it related to the same mood which made Sweden help Hitler before and during WWII, and never having a serious look at that, ever since? I know the prize is ostensibly given by Norwegians.)

Wikipedia is big on the notion of “weasel words“, and rightly so. Deeper than that is what I would call weasel logic. And ever deeper, weasel worlds. To talk about Hitler without ever wondering who his sponsors were, and what they were after, is to live in a weasel world.

I like Elie Wiesel personally. Yet, just as I like Krugman, Obama, and countless others, such as the infamous Jean-Paul Sartre, he likes power even more than truth. OK, It is unfair to put Sartre, who really espoused the most abject terrorism, with the others… As long as individuals prefer power to truth, the spontaneous generation of infamy is insured.

Total oil sales, per day are about 100 million barrels (in truth the cap is lower, see graph above), at, say $100, so ten billion dollars a day, 3.6 trillion a year. The USA uses about 25% of that. Some have incorporated the price of the part of the gigantic American war machine and (what are truly) bribes to feudal warlords insuring Western access to the oil fields, and found a much higher cost up to $11 a gallon.

Ultimately, and pretty soon, in 2016, specialists expect oil prices to explode up, from the exhaustion of the existing oil fields. Then what?

Moreover, in 2016, the dependence upon OPEC, or, more exactly Arab regimes, is going to become much greater than now. What’s the plan of the USA? Extend ever more the security state, and go occupy the Middle East with a one million men army? To occupy, or not to occupy, that is the question.

Is it time for a better plan? And yes, any better plan will require consumers to pay higher energy prices. As consumers apparently want the army to procure the oil, they ought to pay for it.

Note 1: Flying cost at least ten times more in CO2 creation than taking a train. And jet fuel is not taxed, at least until the carbon plan of the European Union starts charging next year, in 2013. In spite of the screaming from the USA and its proxies: it’s funny how attached to subsidies American society can be.

Note 2: Refusing to pay for necessary military expenses through taxation and mobilization, was a big factor in the downfall of the Roman Principate.

The Principate then tried to accomplish defense on the cheap, by using more and more mercenaries. Many of these mercenaries or their children and descendants were poorly integrated in Roman republican culture (say emperors Diocletian or Constantine, let alone Stilicho the Vandal, a century later), so they established theDominate, itself a negation of the Roman republic. Amusingly the Western Franks, those salt water (“Salian“) Franks remembered the Roman republic better than all these imports from the savage East… who could not remember it, they, and their ancestors, having never known it.

Guess what? The USA’s army presently employs 300,000 “private contractors” (aka, mercenaries). Curiously, in that case, it’s not so much to save money, than to extract more money from the system (but that’s another story). Still, it will have the same effect.

oooOOOooo

Is it me? Or are we all truly insane?

At times it does seem as though we, as in mankind, are truly beyond help!

If you detect a note of frustration in the title of today’s Post and the sub-heading above, then you are not mistaken.  It comes from a series of communications that have impinged upon my consciousness over the last twelve hours or so.

This morning Rob I., from here in Payson, emailed me a scan of an article in today’s (Monday) The Arizona Republic newspaper, written by Doyle Rice.  It was entitled Study: Global temps may jump 5 degrees by 2050

I’m going to take the liberty of reproducing it in full.

As the U.S. simmers through its hottest March on record — with more than 6,000 record-high temperatures already set this month — a new study released Sunday shows that average global temperatures could climb 2.5 to 5.4 degrees by 2050 if greenhouse-gas emissions continue unabated.

The study findings are based on the results of 10,000 computer model simulations of future weather overseen by researchers at Oxford University in the United Kingdom.

“These are the first results to suggest that the higher warming scenario could be plausible,” said study lead author Dan Rowlands of Oxford.

It is a faster rate of warming than most other models predict.

Most scientists say that increasing amounts of carbon dioxide in the atmosphere from the burning of fossil fuels such as oil, gas and coal are causing the planet to warm to levels that cannot be explained by natural variability.

The study was published online Sunday in the journal Nature Geoscience and backs up similar predictions from the Intergovernmental Panel on Climate Change in 2007.

The climate models used in the study accurately reproduced actual, observed temperature changes over the last 50 years. Assuming that models that simulate past warming realistically are the best candidates for future warming predictions, the authors conclude in the study that a warming of 2.5 to 5.4 degrees by 2050, compared with the 1960-90 average, is in the “likely range” of climate warming.

The Earth’s average temperature during the decade of 2000-10 was almost a full degree higher than the average from 1960-90, Rowlands said.

I don’t feel too bad at ‘borrowing’ the story above because I also subscribe to the UK’s Met Office News Blog and, guess what, in my ‘in-box’ this morning were two news stories from the Met Office.  Let me take them in this order.

The first one I want to refer to here is this Citizen science looks at future warming uncertainty  and includes the link to the Nature Geoscience magazine article that prompted the story in The Arizona Republic.

This is how it develops,

A project running almost 10,000 climate simulations on volunteers’ home computers has found that a global warming of 3 degrees Celsius by 2050 is ‘equally plausible’ as a rise of 1.4 degrees.

The study addresses some of the uncertainties that previous forecasts, using simpler models or only a few dozen simulations, may have over-looked.

Importantly, the forecast range is derived from using a complex Met Office model that accurately reproduces observed temperature changes over the last 50 years.

The results suggest that the world is very likely to cross the ’2 degrees barrier’ at some point this century if emissions continue unabated.

It also suggests that those planning for the impacts of climate change need to consider the possibility of warming of up to 3 degrees (above the 1961-1990 average) by 2050, even on a mid-range emission scenario. This is a faster rate of warming than most other models predict.

Just go and read that last paragraph again: “This is a faster rate of warming than most other models predict.

Then the next item from the Met Office blog was this,  Why is it so warm?  It’s referring to the specific weather conditions in the UK at present:

The last few days have been unseasonably warm but why is this happening so early in the year? The answer lies largely in the air flow directly above the United Kingdom but more importantly where that air has come from.

Just a few paragraphs down we read, “we have seen a new record high for Scotland in March as the temperature reached 22.8 °C  [73.04 °F] at Fyvie Castle in Aberdeenshire on Sunday 25 March.”  So another temperature record!

I had a quick call with Martin Lack about an hour before starting this Post and he pointed me to the Australian website of CSIRO.  There we find the latest State of the Climate report, from which we read,

The previous State of the Climate, released in March 2010 highlighted a multi-decadal warming trend over Australia’s land and oceans, an increase in record hot days and decrease in record cold days across the country, a decrease in rainfall in southwest and southeast Australia, an increase in global sea level, and increases in global greenhouse gas concentrations.

Do read the full report starting here.  Or if you want a video to watch, then here it is:

Dr Karl Braganza from the Climate Monitoring Section of the Bureau of Meteorology discusses the State of the Climate in 2012.

Also on the CSIRO website is a small piece saying,

Planet Under Pressure 2012

Scientists from around the globe are meeting in London in March to discuss ‘solutions, at all scales, to move societies on to a sustainable pathway’. Planet Under Pressure 2012 is designed to bring together senior policymakers, industry leaders, NGOs, young scientists, the media, health specialists, and academics from many disciplines.
25 March 2012

Meeting to discuss ‘solutions, at all scales, to move societies on to a sustainable pathway’.  Any rational thinking person on this planet if given a chance to reflect on the science knows we have to change our ways.  And the means to do it are clear; we are not talking rocket-science here.

So when Martin Lack catches my attention with a recent piece entitled The seven woes of the Tea Party and I am linked to this article by Rick Santorum, I feel as though it must be me!  This is what Mr. Santorum writes:

The Elephant in the Room: Challenging science dogma

As with evolution, the ‘consensus’ on climate change has become an ideology.

Questioning the scientific consensus in pursuit of the truth is an important part of how science has advanced through the centuries. But what happens when the scientific consensus becomes an ideology that trumps the pursuit of truth? Answer: Those making legitimate inquiries are ostracized, the careers of dissenters are destroyed, and debate is stifled.

Unfortunately, I am referring not only to the current proponents of the theory of man-made global warming.

With the penultimate paragraph reading thus,

Why? Well, maybe because Americans don’t like being told what to believe. Maybe because we have learned to be skeptical of “scientific” claims, particularly those at war with our common sense – like the Darwinists’ telling us for decades that we are just a slightly higher form of life than a bacterium that is here purely by chance, or the Environmental Protection Agency’s informing us last week that man-made carbon dioxide – a gas that humans exhale and plants need to live, a gas that represents less than 0.1 percent of the atmosphere – is a dangerous pollutant threatening to overheat the world.

Frankly, I am lost for words and probably best that I am!  Lost because irrespective of political ‘left’ or ‘right’ the science of where this so-called intelligent species we call homo sapiens is heading, is beyond question.  I use the phrase ‘beyond question’ not as a statement of fact but as a statement of truth.  For science, as this non-scientist understands it, is about distinguishing the truth from ‘non-truth’.

Our beautiful companions for thousands of years truly do know better.  That’s the truth you see in those eyes below.

The truth is always clear, Mr. Man. Just open your eyes!

Meating climate change!

An interesting reflection on the rearing of cattle and an ‘Anti-Meat pill!  No kidding!

I was vaguely aware of the contribution of cattle towards the overall rise in greenhouse gases.  A very quick web search found this news item from the United Nations which included,

29 November 2006 – Cattle-rearing generates more global warming greenhouse gases, as measured in CO2 equivalent, than transportation, and smarter production methods, including improved animal diets to reduce enteric fermentation and consequent methane emissions, are urgently needed, according to a new United Nations report released today.

“Livestock are one of the most significant contributors to today’s most serious environmental problems,” senior UN Food and Agriculture Organization (FAO) official Henning Steinfeld said. “Urgent action is required to remedy the situation.”

But what prompted me to look a little closer at this was a recent article on the Big Think website that was entitled, The Anti-Meat Pill: Human Engineering to Combat Climate Change.

Let me quote a little from the article, presented on the Big Think website by Daniel Honan.

NYU Bio-ethicist Matthew Liao has caused a stir recently with a forthcoming paper that explores the biomedical modification of humans in order to stop us from consuming red meat.

and a paragraph later continued with,

In a forthcoming paper to be published in Ethics, Policy and the Environment, Liao suggests that humans might take pills to bring about mild nausea to rid ourselves of our appetite for red meat. This would have a mitigating effect on climate change, he argues.

Liao refers to studies such as a widely-sited UN report that estimates 18 percent of greenhouse emissions come from livestock, which is a higher share than transportation. Another report, from 2009, estimates livestock emissions are significantly higher, at 50 percent. Fact of life: cows fart. Other negative impacts of increased livestock farming includes deforestation and a drain on water supplies.

The Internet rapidly found Matthew Liao’s website and from there the paper referred to above, which is introduced thus,

Professor Matthew Liao of New York University

Anthropogenic climate change is arguably one of the biggest problems that confront us today. There is ample evidence that climate change is likely to affect adversely many aspects of life for all people around the world, and that existing solutions such as geoengineering might be too risky and ordinary behavioural and market solutions might not be sufficient to mitigate climate change. In this paper, we consider a new kind of solution to climate change, what we call human engineering, which involves biomedical modifications of humans so that they can mitigate and/or adapt to climate change. We argue that human engineering is potentially less risky than geoengineering and that it could help behavioural and market solutions succeed in mitigating climate change. We also consider some possible ethical concerns regarding human engineering such as its safety, the implications of human engineering for our children and for the society, and we argue that these concerns can be addressed. Our upshot is that human engineering deserves further consideration in the debate about climate change.

Now if we go back to that UN article, we can see that emissions from cattle and livestock in general is not a minor issue.

When emissions from land use and land use change are included, the livestock sector accounts for 9 per cent of CO2 deriving from human-related activities, but produces a much larger share of even more harmful greenhouse gases. It generates 65 per cent of human-related nitrous oxide, which has 296 times the Global Warming Potential (GWP) of CO2. Most of this comes from manure.

And it accounts for respectively 37 per cent of all human-induced methane (23 times as warming as CO2), which is largely produced by the digestive system of ruminants, and 64 per cent of ammonia, which contributes significantly to acid rain.

With increased prosperity, people are consuming more meat and dairy products every year, the report notes. Global meat production is projected to more than double from 229 million tonnes in 1999/2001 to 465 million tonnes in 2050, while milk output is set to climb from 580 to 1043 million tonnes.

But modifying humans, frankly, misses the point.

That is unless we wholeheartedly embrace the need to change, to sustain the only planet we can call home, and do it because we care, Planet Earth will do the bioengineering for us – engineering us into extinction.  For example, just cut back on eating meat!  And if you don’t want to do it for the planet, do it for the health of your children as this Health Petition underlines in spades.

So I’m sorry Professor Liao but this seems like a step too far – by a long way.

The governance of Planet Earth

How fundamental reforms of environmental governance are urgently needed.

I must admit that as Post titles go, the one above is about as ‘weighty’ as it comes!  But then again, one might argue as Ronald Firbank, a British novelist, was reputedly to have quoted, “The world is so dreadfully managed, one hardly knows to whom to complain!

One of the great assets of the part of the world where Jean and I live, namely Arizona, is the state university or to give it it’s proper title Arizona State University.  The university has an important School of Sustainability and I subscribe to their regular newsletter.  But it was Rob I. here in Payson who spotted a recent item and forwarded same to me.  Thank goodness because it covered something of supreme relevance to the future.

I’m taking the liberty of reproducing it in full, as follows;

Fundamental steps needed now in global redesign of Earth system governance

Leading experts from around the world, 4 from Pac-12 colleges, argue for immediate ambitious reforms

Some 32 social scientists and researchers from around the world, including Kenneth W. Abbott, a professor of international relations in ASU’s Sandra Day O’Connor College of Law and a Senior Sustainability Scholar in the Global Institute of Sustainability a Senior, are calling for fundamental reforms of global environmental governance to avoid dangerous changes in the Earth system.

Some 32 social scientists and researchers from around the world, including a senior sustainability scholar at Arizona State University, have concluded that fundamental reforms of global environmental governance are needed to avoid dangerous changes in the Earth system. The scientists argued in the March 16 edition of the journal Science that the time is now for a “constitutional moment” in world politics.

Research now indicates that the world is nearing critical tipping points in the Earth system, including on climate and biodiversity, which if not addressed through a new framework of governance could lead to rapid and irreversible change.

“Science assessments indicate that human activities are moving several of Earth’s sub-systems outside the range of natural variability typical for the previous 500,000 years,” wrote the authors in the opening of “Navigating the Anthropocene: Improving Earth System Governance.”

Reducing the risk of potential global environmental disaster requires the development of “a clear and ambitious roadmap for institutional change and effective sustainability governance within the next decade,” comparable in scale and importance to the reform of international governance that followed World War II, they wrote.

In particular, the group argued for the creation of a Sustainable Development Council that would better integrate sustainability concerns across the United Nations system. Giving a leading role to the 20 largest economies (G20) would help the council act effectively. The authors also suggested an upgrade of the UN Environment Program to a full-fledged international organization, a move that would give it greater authority and more secure funding

To keep these institutions accountable to the public, the scientists called for stronger consultative rights for representatives of civil society, including representatives from developing countries, NGOs, consumers and indigenous peoples.

“We should seek input from people closest to the ground, not just from the elites, not just at the 30,000-feet level,” noted Kenneth W. Abbott, a professor of international relations in ASU’s Sandra Day O’Connor College of Law. “Consultations should not take place only at the global scale, where the broadest policies are created, but also at local scales, smaller scales, all scales,” he said.

To improve the speed of decision-making in international negotiations, the authors called for stronger reliance on qualified majority voting. “There has to be a change in international negotiating procedures from the current situation, in which no action can be taken unless consensus is reached among all participating governments,” Abbott said.

The authors also called for governments “to close remaining regulatory gaps at the global level,” including the treatment of emerging technologies.

“A great deal of attention has been given to issues such as climate change, yet nanotechnology and other emerging technologies, which may bring significant benefits, also carry potential risks for sustainable development,” Abbott said.

Relying on research by Abbott and his colleagues at ASU’s College of Law, the authors wrote that emerging technologies “need an international institutional arrangement – such as one or several multilateral framework conventions” to support forecasting and transparency, and to ensure that environmental risks are taken into account.

“Working to make the world economy more green and to create an effective institutional framework for sustainable development will be the two main focal points at this summer’s United Nations Conference on Sustainable Development in Rio de Janeiro,” Abbott said. “This article was written to bring urgency to those discussions and to outline specific ‘building blocks’ for a more effective and sustainable Earth system governance system.”

The authors also argued for increased financial support for poorer nations. “More substantial financial resources could be made available through novel financial mechanisms, such as global emissions markets or air transportation levies for sustainability purposes,” they wrote.

Lead author Frank Biermann, of Free University Amsterdam and Lund University, Sweden, said, “Societies must change course to steer away from critical tipping points in the Earth system that could lead to rapid and irreversible change. Incremental change is no longer sufficient to bring about societal change at the level and with the speed needed to stop Earth system transformation.

“Structural change in global governance is needed, both inside and outside the UN system and involving both public and private actors,” said Biermann, who also is chair of the scientific steering committee of the Earth System Governance Project.

All 32 authors of the Science article are affiliated with the Earth System Governance Project, a global alliance of researchers and leading research institutions, specializing in the scientific study of international and national environmental governance. ASU’s Abbott is one of some 50 lead faculty of the Earth System Governance Project. Lead faculty are scientists of high international reputation who share responsibility for research on earth system governance. Additional information is at http://earthsystemgovernance.org.

In that first paragraph, it was reported that the March 16 edition of the journal Science carried the argument put forward by the scientists.  Here the link to that argument which also includes a link to the full text from which I quote the abstract,

Navigating the Anthropocene: Improving Earth System Governance

Science assessments indicate that human activities are moving several of Earth’s sub-systems outside the range of natural variability typical for the previous 500,000 years (12). Human societies must now change course and steer away from critical tipping points in the Earth system that might lead to rapid and irreversible change (3). This requires fundamental reorientation and restructuring of national and international institutions toward more effective Earth system governance and planetary stewardship.

Optimistically unrealistic!

A reflection of our unconscious minds – and the potential perils ahead.

Last Monday, March 12th, the BBC aired a programme under their excellent Horizon science series.  This programme was entitled, Out of Control?  Here’s how the programme was introduced,

We all like to think we are in control of our lives – of what we feel and what we think. But scientists are now discovering this is often simply an illusion.

Surprising experiments are revealing that what you think you do and what you actually do can be very different. Your unconscious mind is often calling the shots, influencing the decisions you make, from what you eat to who you fall in love with. If you think you are really in control of your life, you may have to think again.

The whole 60 minute programme was fascinating right from the start when Professor Nobre introduced the secret world of our unconscious mind.  Professor Anna Nobre heads The Brain & Cognition Laboratory, a cognitive neuroscience research group at the Department of Experimental Psychology in the University of Oxford.

For starters, how much of your mind do you think is your conscious mind as opposed to your unconscious mind?  Watch this clip and be amazed!

“Are you in control of your unconscious, or is it in control of you?”

So let me link how our mind works to something more relevant today than possibly any other aspect of life.

I’m thinking of the fundamental question that bothers me and, perhaps millions of others.  That question being: “Why, with the overwhelming scientific evidence that man is critically threatening the planet’s biosphere upon which we all depend, is there not an equally overwhelming global commitment for change to a sustainable way of life?

Take, for example, this compelling story.

Last Saturday the BBC News website published a report by Richard Black, the BBC’s Environment correspondent, that opened thus,

An eminent UK engineer is suggesting building cloud-whitening towers in the Faroe Islands as a “technical fix” for warming across the Arctic.

Scientists told UK MPs this week that the possibility of a major methane release triggered by melting Arctic ice constitutes a “planetary emergency“. [my emboldening]

The Arctic could be sea-ice free each September within a few years.

and later goes into this detail (do please read it all, it’s only a few minutes of quiet reading),

On melting ice

The area of Arctic Ocean covered by ice each summer has declined significantly over the last few decades as air and sea temperatures have risen.

For each of the last four years, the September minimum has seen about two-thirds of the average cover for the years 1979-2000, which is used a baseline. The extent covered at other times of the year has also been shrinking.

What more concerns some scientists is the falling volume of ice.

Analysis from the University of Washington, in Seattle, using ice thickness data from submarines and satellites, suggests that Septembers could be ice-free within just a few years.

Data for September suggests the Arctic Ocean could be free of sea ice in a few years

“In 2007, the water [off northern Siberia] warmed up to about 5C (41F) in summer, and this extends down to the sea bed, melting the offshore permafrost,” said Peter Wadhams, professor of ocean physics at Cambridge University.

Among the issues this raises is whether the ice-free conditions will quicken release of methane currently trapped in the sea bed, especially in the shallow waters along the northern coast of Siberia, Canada and Alaska.

Methane is a much more potent greenhouse gas than carbon dioxide, though it does not last as long in the atmosphere.

Several teams of scientists trying to measure how much methane is actually being released have reported seeing vast bubbles coming up through the water – although analysing how much this matters is complicated by the absence of similar measurements from previous decades.

Nevertheless, Prof Wadhams told MPs, the release could be expected to get stronger over time.  “With ‘business-as-usual’ greenhouse gas emissions, we might have warming of 9-10C in the Arctic.  That will cement in place the ice-free nature of the Arctic Ocean – it will release methane from offshore, and a lot of the methane on land as well.”

This would – in turn – exacerbate warming, across the Arctic and the rest of the world.

Abrupt methane releases from frozen regions may have played a major role in two events, 55 and 251 million years ago, that extinguished much of the life then on Earth.

Meteorologist Lord (Julian) Hunt, who chaired the meeting of the All Party Parliamentary Group on Climate Change, clarified that an abrupt methane release from the current warming was not inevitable, describing that as “an issue for scientific debate”.

But he also said that some in the scientific community had been reluctant to discuss the possibility.

“There is quite a lot of suppression and non-discussion of issues that are difficult, and one of those is in fact methane,” he said, recalling a reluctance on the part of at least one senior scientists involved in the Arctic Climate Impact Assessment to discuss the impact that a methane release might have.

Reams of other factual evidence shows that mankind may have only a few years left to stop the planet going into a runaway condition that would then extinguish much of the life on Earth!

So what’s stopping us?

Dr. Sharot

Well back to that Horizon programme.  In the programme, Dr. Tali Sharot of University College London explains how we are all optimists despite the risks.  I.e. our unconscious mind deliberately prevents negative information from affecting our conscious mind, our conscious judgment.

In an experiment, an individual is asked to guess the likelihood of a whole range of outcomes, 80 in all.  Ergo, you see a gentleman guessing the likelihood of cancer as 18%, of a bone fracture as 10%, of Alzheimer’s as 2%, and so on.

In some cases he guessed a pessimistic probability, in others an optimistic probability.  After each guess he was shown the correct probability.  E.g. cancer 30% vs his estimate of 18%, for a bone fracture 34% vs his guess of 10%, and the risk in reality of Alzheimer’s is 10% versus his instinct of just 2%.   I’ve just quoted his optimistic guesses, in many questions his guess was a pessimistic view, i.e. he guessed a higher likelihood than the statistical reality.

Then he was asked all 80 questions again, having seen the accurate probability compared to his intuitive guess.

So here’s the fascinating outcome.

Where his instinct was a negative guess versus the statistical probability then he adjusted his mind and was able to quote a more accurate figure the second time around.  But where the reality was more pessimistic than his first guess, then that adjusted knowledge wasn’t retained.  In other words, our beliefs only change when we can adjust to a more positive view of the future.

I just hope I have made that clear.  Readers may like to view an article written by Dr. Sharot published in TIME Magazine in May, 2011, called The Optimism Bias or read the introduction to a lecture given in Seattle in June, 2011;  “A sunny outlook doesn’t just make you a more pleasant companion: Tali Sharot argues that optimism is a tool for survival and happiness that gets us through hard times—even an economic recession. Sharot, author of The Optimism Bias, uncovers myths about optimism, illuminates the ways it can affect our lives, examines why optimism is necessary for us to function, and illustrates how the human brain is extremely adept at turning lead into gold.

A summary of a publication, Sharot, T. (2011). The optimism bias. Curr Biol 21(23), R941-R945, reads,

The ability to anticipate is a hallmark of cognition. Inferences about what will occur in the future are critical to decision making, enabling us to prepare our actions so as to avoid harm and gain reward. Given the importance of these future projections, one might expect the brain to possess accurate, unbiased foresight. Humans, however, exhibit a pervasive and surprising bias: when it comes to predicting what will happen to us tomorrow, next week, or fifty years from now, we overestimate the likelihood of positive events, and underestimate the likelihood of negative events. For example, we underrate our chances of getting divorced, being in a car accident, or suffering from cancer. We also expect to live longer than objective measures would warrant, overestimate our success in the job market, and believe that our children will be especially talented. This phenomenon is known as the optimism bias, and it is one of the most consistent, prevalent, and robust biases documented in psychology and behavioral economics.

More fascinating information can be found at the Affective Brain Lab.

So here’s the crunch!

Our bias towards an optimistic future is a “tool for survival and happiness that gets us through hard times.”  But if that ancient bias is preventing mankind from recognising just how close we may be to some form of ‘tipping point’ then this tool for survival may be our undoing.

But if on the other hand, we now unite in changing our ways, first by community then by town then by country our future is incredibly optimistic.

Reading Planet Earth, part Four

The final episode from the series of four 1-hour videos from National Geographic.

The first episode plus the introduction can be seen here, the second episode can be seen here while the third can be seen here.

I wasn’t quite sure what to expect from this last episode.  The third episode had shown how good science could determine the deadly cause and effect of past times and enact critically important solutions.  Well, the final episode had the same underlying theme.  That despite the huge scale of change and transformation required by millions of people to restore the planet to health, it’s not impossible, not by a long chalk.

So I will close these past four Posts by thanking Dogs of Doubt for first bringing these videos to light.  I truly hope that they have been for you as  Perfect Stranger described them in his Post, “they explained so much that it is impossible not to recognize the changes we have made to our environment.”  Nothing to add to that.
