On Greta Thunberg: A Letter to my Non-Western Friends




Dear non-Western friends,

first of all, let me tell you that I understand your perplexity about Greta Thunberg. I understand how you see this latest stunt of the Western Media of naming her "Person of the Year." From your viewpoint, it looks just like another trick of the West, one among many. And I understand that it makes you even more suspicious that the whole story of climate change is nothing but a hoax created by the Western Empire to maintain its grip on the whole planet.

Yes, I understand. But I would like to ask you to make an effort to understand us, the Westerners. You see, sometimes I have a feeling that one of the characteristics of Hell could be that the people who are in it don't realize that they are in Hell. It would be truly wicked, but it was a Western poet, Baudelaire, who said that the best trick of the devil is to convince you that he doesn't exist. So, if Hell is a place where you are told lies about everything, including that you are not in it, then we Westerners are truly living in Hell, at least a certain kind of hell.

It is not just lies, it is the kind of lies. The Western media have evolved into a machine for manufacturing fear and hatred. Anyone, any group, any belief, can be destroyed by this machine. And you cannot do much to fight back. If you doubt the official narration, you are a conspiracy theorist. If you plead for peace, you are Putin's stooge. If you protest against your government, you are a terrorist. If you deny the role of the West in leading the world, you are a traitor. And, on top of that, most Westerners are convinced that propaganda is a thing of the non-Western world and that their media are free and independent. Indeed, Baudelaire was right.

Of course, don't make me say that the non-Western world is a Paradise of truth. All nations, all states, all cultures, have their biases, their filters, their entrenched beliefs, and, in many cases, their propaganda machines. Every one of us, Westerners and non-Westerners, sees the world through the filters that our culture, our traditions, and our media place in front of us.  But you, non-Westerners, have a possibility that's denied to us, Westerners. You can use English to peer into the Western media without being embedded in it. And, as I said, I understand that often you don't like what you see.

And so, we are back to Greta Thunberg. Of course, I understand that this girl is not a "grassroots" phenomenon as some might want to believe. She is supported by a top-class team of media experts, she couldn't possibly fight the Western Media Behemot alone. And I understand that her message may be misunderstood, mongrelized, and exploited for yet another round of greenwashing. I know that.

But that's not the point. It is how the appearance of Ms. Thunberg has been both amazing and unexpected. If she is a product of propaganda, then it an unusual kind of propaganda. It would be the first time in many decades that our media are presenting to us a message that's not based on the idea of something or someone evil to be destroyed. This girl crashed through all the media barriers with just a simple message: the truth about climate change. She wasn't telling us to kill or hate anyone, she was just telling us to work together to ensure that her generation could have a future. And she carried the message with an inner force, a way of posing herself, a capability of saying things straight that was nearly unbelievable. It is amazing how she attracted upon herself all kinds of insults, abuse, and curses, but nothing really stuck on her. You remember Ronald Reagan's "Teflon presidency"? Well, this girl is not just Teflon coated: she wears a Mythril armor like the heroes of the trilogy of the ring.

I understand that it is possible that this girl will disappear from the mediasphere in a short time, as it happens for most ideas over the Web, nowadays. But she may turn out to be something more, maybe not the specific person of Greta Thunberg, but in the message she represents. A strong message telling humankind to respect the things that make humankind live: our planet and all the living beings in it.

Let me tell you of something I learned not long ago when I was in Iran. It was the time of the Arbaeen, the commemoration of the martyrdom of Imam Husayn ibn Ali, forty days after the Day of the Ashura. Someone told me (or maybe I read somewhere) that "Imam Husayn is a figure that we Shi'ites offer as a gift to the whole humankind as an example of virtue and of justice." And that struck me as something worth remembering. In all cultures, we have something or someone we revere as a treasure: a person, a poem, a work of art, a way of seeing the world. And these treasures, I think, we should share with the rest of humankind as gifts.

Now, of course, I don't have the authority to say what the entity we call "The West" should or should not do. For sure, we shared with the world plenty of poisoned gifts in the past. But this girl, Greta Thunberg, might be a true treasure, a gift we could offer to the rest of the world. For once, there would come from the West a message of peace and harmony. Could that really happen? Maybe.

The Effect of the Sanctions: Is Iran Cracking Down Under the Strain?



I have to confess that the title of this post is a little of a clickbait. In reality, I will tell you more about Italy than about Iran. But, perhaps, from the story of how Italy reacted to the international economic sanctions imposed on the country in 1935, we can learn something about what could be the result of the current sanctions on Iran. Above, a photo from 1935, it shows a stone slab with the engraved words. "On 18 November 1935, the world besieged Italy. Perennial infamy on those who favored and consumed this absurd crime." Most of these slabs were destroyed after the defeat of Italy in WW2, but some can still be found.


In 1935, Italy invaded Ethiopia, at that time the only remaining free African country. Why exactly that happened is a long story. Let me just say that, in part, it was a revenge for a defeat suffered long before, when an early attempt at invading Ethiopia had failed. In part, it also had to do with reacting to the financial crash of 1929: governments often tend to seek for external enemies to distract people from internal troubles. Then, in part, it was seen as a way to displease the hated British, seen as guilty of not providing for Italy the coal that the Italian economy needed. And, finally, it had to do with some nebulous dreams about rebuilding the Roman Empire. It may sound silly, today, but if you read what people wrote at that time in Italy, that idea of creating a new Roman Empire was taken seriously.

Whatever the reasons, in 1935 the Ethiopian army was overwhelmed by the modern weaponry deployed by Italy, planes and tanks, with the added help of poison gas bombing, a military innovation for that time. The final result was that the King of Italy gained the dubious honor of taking for himself the title of "Emperor of Ethiopia" and that Italy gained "a place in the sun" in Africa, as the propaganda described the results of the campaign.

A victory, yes, but a hollow one. From the beginning, Ethiopia was only a burden for the Italian economy and the costs of the military occupation were just too much for the already strained Italian finances. The final result was perhaps the shortest-lived empire in history: it lasted just five years, collapsing in 1941 when the Italian forces in Ethiopia were quickly defeated by a coalition of Ethiopian and allied forces.

An interesting side effect of the invasion of Ethiopia was the story of the imposition of economic sanctions on Italy by the League of the Nations. It was a half-hearted effect to stop the invasion, but the war lasted just 8 months and the sanctions were dropped just two months afterward. Their effect was nearly zero in economic and military terms but, in political terms, it was a completely different story and the consequences reverberated for years. Here are some of these consequences:

1. The Italians were not only appalled at the sanctions, they were positively enraged. According to the international laws of the time, for a state to attack another was not in itself a crime (unlike the use of chemical weapons, but that came to be known only later). So, most Italians felt that they were punished for having done something -- annexing an African country -- that the other Western Powers had done before without anyone complaining. The result was a burst of national pride and a strong wave of popular support for the war. That generated also a wave of personal popularity for the Italian leader, Benito Mussolini, seen as the one who was making Italy great again (some things never change in politics).

2. The sanctions transformed a war waged on a poor and backward country into something epic and grandiose. Italians perceived the struggle against a coalition of the great powers of the world, Britain in particular. And, by defeating this coalition, Italy showed that it was a great power, too, on a par with the others. This idea had terrible consequences when it led the Duce, Benito Mussolini, to think that Italy could match the military capabilities of the major world powers in WW2.

3. The government propaganda in Italy used the sanctions to magnify the importance of the Ethiopian campaign, seen as a turning point in the quest for a new Italian Empire. As a result, Ethiopia became a national priority, to be kept at all costs. At the start of WW2, Italy had more than 100,000 fully equipped troops there. Without the possibility of being resupplied from Italy, these troops had no chances against the British and they were rapidly wiped out. What might have happened if they had been available in other war theaters? It is unlikely that the final outcome of WW2 would have changed, but, who knows? The battle for Egypt in 1942 could have had a different outcome if Italy had been able to field 100,000 more troops there and, maybe, taken the Suez canal.

This catalog of disasters is so impressive that we might wonder if the sanctions were not just the result of incompetence and idiocy, but of an evil machination. Could it be that the British had wanted Italy to engage in an adventure that was sure to lead the country to ruin, later? Of course, it is unlikely that the British had been planning for exactly what happened, but it is not impossible that they understood that the Italian military apparatus would be weakened by the task of keeping Ethiopia and that would make Italy a less dangerous adversary in case of an all-out military conflict. If the British had planned that, they truly deserved the reputation they had at the time (and that they still have) described with the name of the "Perfidious Albion."


That's the story of the sanctions against Italy, now let's go to the sanctions against Iran. First of all, a disclaimer: I don't claim to be an expert in Iranian matters and politics. I don't speak Persian and I visited Iran only once in my life. So, I can only claim to have read and studied about Iran for years and to have many Iranian friends and acquaintances. Yet, if I think of the idiocies that you can read on the Western Media about Iran, I feel I can do something better, maybe useful for the readers of this blog. So, let me take a look at the current sanctions on Iran on the basis of the assumption that Iranian and Italians are very similar people in terms of ideas, temperament, and beliefs -- which I think is true on the basis of my experience.

Then, we know that story rhimes, but never exactly repeats. So, there are many similarities in the story of the sanctions against Iran and those against Italy, but also considerable differences. The main similarity is, of course, that Iranians feel unjustly punished for doing something, starting a nuclear energy program, that other countries could do in the past without anyone punishing them. But note also that the current sanctions on Iran are harsher than anything that was imposed on Italy. When vice-president Pompeo said that the purpose of the sanctions is to starve the Iranians, you get a certain feeling that the matter is deadly serious in a literal sense.

So, what's happening in Iran and what might happen in the future? As I already discussed in a previous post, so far the effect of the sanctions has been limited. But inflation is biting hard the finances of the Iranian Middle Class and the government risks to be soon in trouble in maintaining the services that so far have been provided for free: instruction, health care, and more. In the long run, the cohesion of the Iranian society could be threatened and the recent street disorders could be a symptom of something like that.

The Iranian government is currently led by a moderate, President Rouhani, who stated more than once that he doesn't want to engage in any kind of retaliation. Some Iranians would want a more forceful reaction but, in general, they seem to recognize their weakness in front of the mighty US empire. Fortunately, nobody in Iran seems to be thinking of resurrecting the defunct Parthian Empire, unlike what Italians were trying to do with the Roman Empire in the 1930s. If Iran can hold on long enough, the storm may indeed end.

But what if the sanctions had a true evil purpose in the sense of having the task of pushing Iran to do something stupid, as it was the case with Italy, long ago? Under heavy strain, Iranians could decide that their best bet is for a strong leader who would "Make Iran Great Again." And what could happen if things really go from bad to worse? Iranians could go through the same chain of misperceptions that Italy followed, bolstered by some local success, becoming convinced to be a great power. Then, if an American president wants to obliterate Iran with a nuclear strike, who or what could stop her? Then, if evil has to be, could that be the real purpose of the sanctions?

Hopefully, these extreme scenarios will never take place but one thing is clear to me: sanctions are a bad idea. They are sold to the Western public as something "humane," actually designed to help the people they target to get rid of an evil and oppressive government. It is not like that. Maybe sanctions are not as bad as carpet bombing, but they are a tool to start wars.

RAMSES: The Electric Tractor is Alive and Well in Tehran



The RAMSES vehicle under development in Italy in 2011. In the photo, from the left, the developers: Toufic El Asmar, Paolo Pasquini, and Ugo Bardi.



Maybe you read my descriptions of the "RAMSES" electric tractor that I helped to develop some years ago with funding from the European Commission. It was an interesting project and the result was a practical multi-purpose vehicle for agricultural applications. It was not meant to be a heavy-duty tractor, it was something that could perform many different tasks, from transporting goods to spraying and irrigating. Above, you can see the vehicle in a photo of some years above. And you can read a complete description in a paper that we published in the "Journal of Cleaner Production" (authors U. Bardi. T. El Asmar and A. Lavacchi, vol. 19, pp. 2034-2048 - 203). See also a post on the Cassandra blog

So, I was very pleased last month when I saw a version of the same idea being developed in Teheran by Professor Hossein Mousazadeh at the faculty of Agricultural Engineering. Hossein had been working at the RAMSES project in Italy at the University of Florence and here is his brainchild, "RAMSES 2.0"


Below, another picture of the same tractor, driven by Hossein himself


In comparison with the Italian RAMSES, the Iranian version is similar. It uses lead batteries, too, for the lowest possible cost. But it has a few additional quirks: first of all, it is a hybrid vehicle that can recharge its batteries using a gas-powered, on-board engine. It can also recharge in an emergency using PV panels on top: Iran, just like Italy, is a sunny country. Note also the camera in front, the vehicle can be remote-controlled and it has a certain capability of autonomous motion. Apart from this, it follows the basic philosophy of what an electric agricultural vehicle should be: rugged, simple, as inexpensive as possible.

As you may have imagined, both the RAMSES and the Tehran tractor have remained at the stage of prototypes, so far. The market for electric vehicles seems to be moving from the top toward the bottom, with the great success of the Tesla cars so far not reaching the low-cost side of the transportation market. And, obviously, agriculture is a market where low-cost is a desperate necessity for cash-strapped farmers everywhere. It will take time before electrification reaches the agricultural world. But, eventually, even farmers will have to be weaned from their addiction to oil.

So we are moving slowly toward the energy transition. But, eventually, we'll get there!




Below, yours truly, Ugo Bardi, playing the farmer with the Iranian tractor.

What's wrong with the oil industry? Too many claims of abundance start sounding suspicious


Above: the Financial Times of Nov 29th, 2019. Has the US really become energy independent?


Peak oil theorists have always been the favorite punching ball of mainstream oil pundits but, recently, the attacks against the peak oil idea have started becoming so loud and widespread that I am starting to think that there has to be something wrong with the oil world nowadays. As an especially bad example, I may cite a recent article on Forbes by Michael Lynch. I understand that some people have a bone to pick and they want to pick it clean, but this is a little too much -- there are limits to how nasty one can be, even in a heated discussion. 

Yet, some claims of great oil abundance seem to be based not just on the pleasure of denigrating peak oil theorists but on data said to be real. Just as an example, see a recent article on the Financial Times where we can read that,
The US has cemented its status as a net exporter in world oil markets, a sharp reversal from past years that could affect its ties to foreign allies. 
You may wonder the logic of using the term "cemented," that carries the meaning of consolidating something already existing. Indeed, claims of the US having reached "energy independence" in terms of crude oil had become common after that the US production had exceeded imports -- that meant nothing, of course, it was pure dry-holing. At that time, the US had, and still has, a deficit of nearly 3 million barrels of oil in terms of import/export balance, as you can see in the figure below. (image from SeekingAlpha)

The EIA data for crude oil confirm that in November of this year the US had a DEFICIT of 2.7 million barrels per day in the import/export balance. So, how can the FT claim that the US is a net exporter, then? Simple: under the category of "oil" they sum crude oil and oil products. The latter include refinery products such as kerosene, diesel fuel, lubricants, etc. And, indeed, recently the sum of the exports of these two categories has touched and slightly exceeded the curve of the crude oil imports. 

Does that mean that the US is now "energy independent" in the sense that it exports more oil than it imports? Not at all. That would be true ONLY if the exported products were wholly made with US oil -- which obviously cannot be the case. The US production, nowadays, comes in large part from shale oil, which is light oil. But refineries prefer to use heavy oil, which is imported from Canada and other regions outside the US. The refined products made from this oil can be counted as "oil exports" but it is not oil that was produced in the US. If what counts is the US energy independence, then it is obvious that it is just a trick to make the US look like it is producing more than it does. 

It is true that the US oil production keeps increasing, so far, but for how long can it continue growing? Indeed, there seems to be a suspicious excess of glee in these claims of oil abundance. Could it be an attempt to cover some big problems? Hard to say, but one thing is impressive: 2019 should the first year in a decade -- since the great recession of 2009 -- when the world oil production declined (data by Ron Patterson).




The story of peak oil has been a war of opinions and we know that wars are won by those who win the last battle. Mr. Lynch is surely convinced that his opinions on peak oil have been vindicated, but it may be too early for him to take a victory lap. 

Are we looking at the other side of the growth curve

Like Stalingrad: Italy's Concrete Infrastructure is Melting in the Rain


The region of Liguria, within the red circle, is a narrow strip of land stuck between the Appennini Mountains and the Tyrrhenian Sea. It is also a critical element of the transportation system that connects France and the Po valley to the rest of Italy. As you may imagine, this heavily urbanized region is subjected to disastrous floods. The situation became so bad, recently, that the president of the Liguria region declared it was like the siege of Stalingrad, during WWII. The image above is from a presentation by Massimo Lanfranco, highly recommended!



When you have a fame of being a catastrophist or a Cassandra, reading that some of your prophecies turned out to be true may be a little unsettling. But it seems that I understood something correctly with the chapter of my recent book "Before the Collapse," where I described how the world's concrete infrastructure was getting old and decaying and how the situation was going to get worse with time.

In my take of the situation, I was inspired by the collapse of the Morandi Bridge in Genova, Italy, in 2018, but I was sure that worse things were going to happen. And it seems that I was right: the recent disasters in Southern Europe (France, Greece, and Italy) show how roads, railways, and buildings, are fragile, often on the edge of collapse. Rains heavier than usual are sufficient to create disasters, in part because of landslides and floods, in part because of the aged and weakened concrete structures. And, with climate change pressing forward, heavy rains are going to be more and more common.

In Italy, the situation is especially bad in Liguria, the crescent-shaped region that lies South of the Appennini mountains in North-Western Italy. It is a crucial region for the Italian economy: its ports are the gateway to the industrial areas of the Po valley, on the other side of the mountains. Roads and railroads connecting Italy to Southern France go through the narrow strip between the mountains and the sea in Liguria, an area that was heavily urbanized and impermeabilized. Today, it is prone to floods and to all the associated disasters. Almost every year, something horrible happens there -- the collapse of the Morandi bridge was just one case among many. Below, you can see the most recent case of a highway bridge having collapsed. It happened on Nov 24th, fortunately there were no victims (image from Vigili del Fuoco)


That the situation is dramatic starts being perceived. Here is what the President of the Liguria Region, Giovanni Toti, said after the latest bridge collapse.

Siamo in guerra. Siamo a Stalingrado ... La Liguria oggi è isolata come prima degli anni Trenta. Ogni minuto di chiusura sarà un danno incalcolabile per la città, la regione e l’economia del Nord Ovest. .. È come se fossimo in tempo di guerra. Non possiamo reggere oltre la settimana. Il Governo si deve fare carico di tutto ciò che serve. 
We are at war, we are at Stalingrad... Liguria is today isolated as it was in the 1930s... Every minute of closure of the highway is an incalculable damage for the city, the region, for the North-Western economy. It is like wartime. We can't hold more than a week. The Government must intervene with all that's needed. 
Maybe a little exaggerated, but not so much. Our whole civilization is built on concrete structures that may turn to be no more resilient than a sandcastle built on the beach at low tide. And those of us who are Cassandras had noted that before the emergency but, as usual, we were not heard. Here is a snapshot of the first page of the relevant chapter from my book "Before the Collapse"

Denigrating "The Limits to Growth" is Still a Popular Pastime. But can we Learn Something From it?



Many people seem to be surprised when I tell them that I follow the abominable science denial blog "Watts Up With That" kept by Alan Watts. Yes, it is abominable, sometimes, but it has one feature that makes it stand a couple of notches above the other science denial blogs: it is almost never boring, It has the same fascination that you can find in a well-done evil character of a literature piece, think of Shakespeare's Iago in Othello. And sometimes you can learn something even from WUWT: if nothing else about how your enemies think and behave.


The first report to the Club of Rome, the 1972 study titled "The Limits to Growth," is one of the typical bugaboos of those people we call "denialists," people who deny the main findings of climate science. The study didn't consider global warming explicitly, but its results relative to pollution could be seen as hinting at the problem. So, it is not surprising that the same attitude of denial embraces both studies on resource depletion and climate change. No surprise that, in the 1980s, "The Limits to Growth" started to be the target of a denigration campaign that's continuing nowadays in parallel with the one ongoing against climate science. I told the "Limits-Bashing" story in my 2011 book "The Limits to Growth Revisited."

The story is not over. Today, I found Limits-bashing alive and well in a post by Eric Worrall on "Watt's Up With That" (WUWT). The post starts with a citation from an article by Annabel Crabb on ABC news describing the split on climate change that took place 10 years ago in the Australian parliament. The story is not so easy to decipher for someone who is not Australian, but Ms. Crabb attributes the collapse of bipartisan policies on climate change on the actions of MP Andrew Robb who, apparently, had been an early supporter of the ideas of the Club of Rome but who later reversed his position.

Crabb reports:
He (Robb) mentions that when he was a much younger man, he was "a great student" of the Club of Rome, an association of scientists, bureaucrats, politicians and public thinkers who in 1972 published the book Limits To Growth, warning that the world's resources could not withstand the depredations of ceaseless economic growth indefinitely.

Limits To Growth is still the highest-selling environmental book in the history of the world, having sold 30 million copies in more than 30 languages.

But Robb's early fascination with the work gave way to distrust of its conclusions and primitive computer modelling; he says its warnings of resource exhaustion and economic collapse towards the end of the 20th century were overstated.

"The thing they didn't talk about was technology. That you could find gas 300 kilometres offshore, for example, and find a way to bring it onshore. Because of this, the Club of Rome — which was quite a reputable group of people — looked more and more ridiculous as the years rolled on."

The Club of Rome has its critics and its defenders; Limits To Growth was commonly derided by the 1990s as a misguided Doomsday scenario, but has enjoyed something of a renaissance lately. The CSIRO published a paper in 2008 finding that the book's 30-year modelling of consequences from a "business as usual" approach to economic growth was essentially sound.

But what's not deniable is that this work influenced one young man who grew up to be one member of a parliamentary party with a singular role to play in one vote on a policy that would either change or not change the course of a country.

In the end, Ms. Crabb arrives at the surprising conclusion that if the Australian parliament failed to adopt environmental policies it was a fault of a Club of Rome. A bit of a flight of fancy to say the least. It seems more likely that Mr. Robb just thought that a little "Limits-Bashing" was appropriate to justify his actions of 10 years ago. So, he engaged in a few remarkably statements for someone who claims to have been a "Great Student" of the Club of Rome. For instance, the Limits study never said that the collapse of the world's economy was expected "toward the end of the 20th century." (and, about one of Ms. Crabb's statements, 30 million copies sold for The Limits to Growth is a wildly exaggerated number).

More interesting than the somewhat convoluted Australian story is the reaction of Eric Worrall on WUWT. Apparently, he had never heard of the work of Graham Turner, so he engages in a somewhat rambling criticism of The Limits to Growth where he cites Turner more than once. The surprising thing is that Worrall doesn't engage in the usual sneers against the Club of Rome. No, Worrall makes several mistakes, evidently he doesn't know much about dynamic modeling nor about the specific study he is criticizing, but, considering the standards of the WUWT site, it is a reasonably balanced text.

But I said that you can often learn something from WUWT. What is that you can learn in this case? A typical trick they play: they publish a post that looks superficially balanced, but they know that it is a bait for their commenters who will then proceed to state what climate science deniers really think. With this post, as for many others on WUWT, the real learning experience is to read the rabid comments. Just as an example, about Turner's work, we read that "CSIRO is a cesspool of socialist academics including some IP theft specialist employees working for China; yes really!"

And we keep going and we keep learning

Climategate, 10 Years Later: What Can we Learn About it from Memetics?


Ten years ago, on November 20th, 2009, the "Climategate" story broke into the news, worldwide. At the beginning, it seemed to be just part of the heated debate on climate. Then, its true character appeared more clearly: it was a major demonstration of the power of the media to control the memesphere. Above, an image from The Telegraph of Nov 28th, 2009


You may think of "Climategate " as a scandal but, really, it was a startling demonstration of how propaganda can be effective. That dawned on me one day when I was having lunch at the university cafeteria with one of my former teachers. We were chatting of this and that when he came up with something like, "hey, Ugo, did you hear that they intercepted the phone calls of some climate scientists and they confessed that they had altered the data?" I remained frozen, holding my fork in mid-air. This scientist was like a child: outside his narrow field of study, he was unable to critically evaluate the news that he received from the media.

That was not the only experience that showed me that there is something deeply wrong in the way we manage knowledge, but surely it was a big push in that direction. As a scientist, I am trained in the scientific method, not a single rule but a general attitude that says, "verify everything before assuming it is true." Evidently, that doesn't apply to politics, not even to those issues that are important for the survival of humankind. But how is it that people are so easily swayed by propaganda?

As I discuss in my latest book, "Before the Collapse," believing in what looks true is a time-honored tradition. It is a quick and dirty epistemological trick that often works in situations where you have to take a rapid decision based on insufficient data. (say, you stumble into a sabertooth tiger that looks hungry -- it is safe to assume it is). It even has a name, the term "zetetics" is used sometimes, coming from a Greek word that means "I search." This approach is used also when you are overwhelmed by data and you have to simplify. The idea of zetetics is to avoid all kinds of theory or models: what you see is what is true. It is the attitude of flat-earthers: the Earth looks flat, then it has to be flat, and the hell with those "models" trying to show that it is round.

In the case of Climategate, the basis of the problem is that climate science is a complex story that proposes something that looks contrary to fact: that the Earth's climate changes. A good zeteticist would never accept that: climate looks stable, then it has to be stable. Then, why those scientists insist that it is not? Something smells bad, here. And there comes Climategate to confirm that there is something bad in the story, indeed. Of course, there was nothing in the mails that were released that could even vaguely indicate that climate scientists were conspiring in order to swindle humankind by tampering with their results. Out of 160 Mb of data, all that could be found were a couple of sentences taken out of context ("hide the decline" or "Mike's trick") and some legitimate personal opinions. But, apparently, if scientists could be made to look evil, then they had to be evil! Zetetics at work.

But it wasn't just that: Climategate was especially impressive not just for its rapid diffusion, but also for how resilient it was to all attempts to dislodge it from the public consciousness. Even today, 10 years later, you can read plenty of commentaries on the Web showing that many people are still convinced that the scientists involved with Climategate were doing something ugly and horrible, although it isn't clear to them exactly what. So, we can be easily swindled by this kind of hoaxes: Climategate is just one of them.  But can we at least learn something from these stories?

Yes, we can. For me, Climategate was the start of a research that went in some depth into understanding how the mechanisms of what we call "consensus" work. With some colleagues of mine, we discovered the existence of something called "memetics" and how memes diffuse through the "memesphere." Being good scientists, we even published papers in this subject, trying to define what pushes a meme to become "viral" as it is fashionable to say nowadays. In one of these papers, we observed that there is a difference between "bottom-up" memes (that is, the true viral memes) and memes diffused from above (we call them "fall-out" memes).

So, here are some data for "Climategate" obtained from Google trends. Note the abrupt "spike" in the signal: according to our models, it shows that the story was pushed into the public consciousness mainly by the media. What we see in the data is a reflection of how the public was driven to search more about what they had read in news sites or heard on TV,




Here are some more data on the peak of interest




Note also how the peak goes in bumps. It is another characteristic of fall-out memes. They are pushed from above by the timed release of new data that keep the interest of the public alive. A meme managed in this way is like a city attacked by successive waves of bombers.

The searches for the Climategate story rapidly abated, after about one month the "infective" phase of the meme was over. But the meme remains dormant like an encysted virus, you can see that from the fact that the "tail" never goes exactly to zero. It is remarkable how "Climategate" has a search volume comparable to that of "Russiagate" despite being ten years old -- an age that for news exceed that of the Biblical Methuselah.



So, did the Climategate meme have something special that made it so resilient? I'd say no: it was just one of those memes that live on pointing at an enemy of the people ("orange man bad"). These memes are extremely effective and long-lasting (see this post of mine for a series that includes Jews eating children and Marie Antoinette telling the hungry people of Paris to eat cake). There is very little that can be done to stop them once they start growing along their viral trajectory. Rational arguments against memes are not more effective than they would be with biological viruses. Just like a virus doesn't "see" the macroscopic world in which we live, a meme doesn't "see" the real world. The memesphere is another dimension.

Still, we are not completely defenseless against memetic attacks. We could say that the false information (aka fake news) that pervades the Web is a form of pollution. Then, it could be reduced by using the same methods used to reduce the real world's pollution. That is, forcing polluters to clean up their act and to pay for the damage they caused. That could be applied also to the people who spread fake news on the Web but, unfortunately, right now, those who claim to be fighting fake news are also the main producers of fake news, so it is hard to think that they would act against their own interests. But, in the long run, something good could be done using this approach.

Then, at the individual level, we can learn from biology how to fight back against memetic attacks. For instance:
  1. Avoid contact with contaminated areas: That means mainly avoiding the mainstream media (MSM), but also social media can be highly toxic. They are carpet bombing your brain with destructive memes every day: if you don't dodge them, eventually they'll destroy your defenses and with that your brain.
  2. Avoid contact with infected people. Don't debate with people who have bought into some especially malign meme: it is like thinking that you can cure someone from aids by sleeping with him or her. It is much more likely that you will be infected yourself.
  3. Build up your immune system. Create a meme filter: any and every meme that arrives to you, especially if it is from the MSM, has to be considered false unless proven to be true.
  4. Reinforce your defenses. Counter the MSM and social media with other sources of information. Blogs are an especially effective way, not for nothing they are under continuous attack, nowadays. But as long as you have access to independent information (we don't know for how long that will be possible), use it. Just don't forget that even what you learn from blogs has to be considered false unless proven true. Otherwise, you risk being infected by opposed but just as malign memes.

Of course, that's hardly sufficient to stop the diffusion of evil memes but, at least, it will help you maintain a certain degree of mental sanity. And that's the best we can do for now.

Before The Collapse: The New Book by Ugo Bardi



My new book on collapse is out, published by Springer. You can find it at the Springer site at this link (priced in Euro) and at this link (priced in dollars). You can find it also on most Web sites that sell books.



Collapse is a popular subject nowadays, so I thought I could add some more confusion to the already ongoing mess by publishing this new book "Before the Collapse: A Guide to the Other Side of Growth."

If you follow the "Cassandra's Legacy" blog, you know that collapse is a subject that I touch frequently and that two years ago I published a book titled "The Seneca Effect," that made an explicit reference to the Roman philosopher Lucius Annaeus Seneca, whose work I took as the first mention in history of collapse as a normal feature of the universe. "The Seneca Effect" was not a difficult book to read but it was a technical book, dedicated to people interested in subjects such as system dynamics. It was also priced accordingly.

So, the second book was thought at the beginning as a simplified version of the first to be placed in the category of "trade books" destined to the general public (also at a lower price). But, eventually, as the text grew, it became a different book. It maintained some elements of the first, but it included new examples, new ideas, new subjects, and a new slant. It became a practical manual on how to deal with collapse, although it does not neglect some scientific elements of the story (and for this I have to thank my unicellular assistant, Amelia the Amoeba. You see her in the picture on the right, as she appears in the book. She is a nice girl except for her habit of eating human brains, but - hey! - nobody's perfect!)

So, the choice of the title, "Before the Collapse," to emphasize that we still have time to prepare for "The Other Side of Growth," the dreaded social and climatic collapse that, by now, appears unavoidable. Yes, but that doesn't mean we have to fall into the doom and gloom attitude that seems to be spreading among those who take the time to examine the situation. The gist of the book is that collapse is not an exceptional event, it is the way the universe works (collapse is not a bug, it is a feature). It is the way the universe uses to get rid of the old to make space for the new. And we badly need to get rid of the old things and ideas that have led us to where we are. As someone said, "collapse early and avoid the rush!" So, sometimes you can't avoid collapse, but you can always be prepared for it.

But "BTC" is not just about the "big one," the civilization collapse that we are fearing so much and for good reasons. Collapse, it seems, has a certain fractal character. There are big and small collapses and the small ones are more frequent and can affect anyone. So, BTC tries to help the reader to navigate among the perilous cliffs of life that involve such things as bankruptcy, natural disasters, structural collapses, wars (large and small), social unrest, business competition, zombie apocalypses and more. It is a sort of a smorgasbord of collapses: there is something for everyone.

Writing a book is a big effort and once you have a printed copy in your hand you always feel like you would have written it in a different way if you were to start anew. But books are books, this one is written and I hope you'll like it. I dedicated it to my two granddaughters, Aurora and Beatrice, who were both born while it was being written. While writing, I couldn't' avoid realizing that their life will be most likely way more "bumpy" than ours, but I don't despair for their future. Humans are an adaptable species and our descendants will adapt to the mess their ancestors created and, I hope, will find ways to clean it up.

And so, onward, fellow humans!

What Future for Africa? A Report from the Meeting of the Club of Rome in Cape Town





Manphela Ramphele (*) and Sandrine Dixon-Decleve, the co-presidents of the Club of Rome, at the start of the meeting of the Club in Cape Town on 5 November 2019 (**). These are somewhat rambling and incomplete notes written immediately after the end of the meeting.


Africa? What is Africa, exactly? A continent? A nation? A world in itself? Surely, it is enormous, variegated and complex. Personally, I had never crossed the equator in my life but these few days in Cape Town were enough to give me a new perspective of the world. It started with a small epiphany received from a Kenyan lady at the meeting of the Club of Rome who told me, "things are happening here."

Indeed, things are happening in Africa. You can see it from the data and the statistics but, perhaps, it is more a sensation. It is like a humming, a buzz, the feeling that something gigantic is stirring down below in the bowels of the continent. Something is happening, here.

When you land in Cape Town, you are struck first by the landscape: enormous rocky mountains all over the horizon -- remnants of the immense geological forces that shaped this section of the continent. Then, you move along the townships of Khayelitsha ("new home"), a seemingly infinite expanse of wood and iron shacks. Think of a European Gipsy camp multiplied by a factor 1,000 or more: the contrast with the skyscrapers, downtown, couldn't be starker. Not as grandiose as the mountains, nevertheless these settlements give you a sensation of human resilience, of the willingness to endure and survive, no matter how hard the conditions are.

And then you start getting a feeling of the place. It takes some time but, eventually, the pieces of the puzzle start coming together. Well beyond the trinkets for tourists and the cheap folklore, there are such things as an African vision, an African way, an African logic, and a certain feeling of being African. Of course, Africa is not a nation and it may never be one. Besides, it is sharply separated in two parts by the Sahara desert. But there is a certain continuity, a certain degree of shared beliefs that pervades the continent.

For instance, an African participant to the meeting generated another small epiphany for me when he said, "when we Africans disagree, we don't vote like you Westerners do. We discuss until we find an agreement and then there are no more contrasts." My first reaction as a Westerner was that it would never work in the West, but maybe that's because we have never been educated to believe that it is always possible to find an agreement when we need one. Then, of course, it may not work so perfectly even in Africa but, at least, if you start with the idea that you should strive to reduce contrasts, at least you won't exacerbate them. On this point, I had another epiphany from the words of a Chinese member of the Club who, in debating with someone else, said, "I am against you, but only 90%. I am with you 10%, and that may change to 90% with you: it is the principle of the Yin and the Yang, things always change and then become the same again." Maybe the Chinese and the Africans have something in common, for sure there is some wisdom, here.

So, there is such a thing as "Africa" that goes beyond the name of a continental plate. And there are people who define themselves as "Africans," a term that goes beyond the fact that they live on a certain portion of the Earth's continental plates. For sure, both Africa and the Africans have been badly misunderstood. If you live in Europe, and in Italy in particular, you can't avoid noting that Africans are seen as somewhat less than human, bands of renegades who land on our shores to steal our jobs and rape our women, people who can't keep themselves from breeding like rabbits. I am shocked myself at what I just write, but if you live in Italy that's what many people seem to think. The outburst of racism, there, has been simply unbelievable, but we have to believe it because it has happened.

Africa and the Africans have been invaded, enslaved, insulted, exploited, exterminated, misunderstood, slighted, despised, and much more. And yet, they are here. Despite all the problems: crime, corruption, violence, poverty, inequality, and what you have, Africa is here and Africans have something to say to the rest of the world. Will they be able to do that?

The challenges for Africa are enormous although, perhaps, not harder than for the rest of the world. One of these challenges is that the economic powerhouse of the sub-Saharan region, South Africa, is an economy that was built on coal, just like the European economies. And as all economies built on fossil fuels, the problem is how to move away from the original source of power. Clearly, South Africa is in big trouble, here. Apart from the need for phasing out coal, it is also a problem of supply, as it seems clear from the production data which indicate a peak in 2014.


In addition, the South African coal-fired power plants are obsolete and need to be phased out within the next two decades. South Africa also has a modest nuclear power production, but it doesn't seem to have the resources to increase it -- perhaps not even to maintain it. Then, there would be good chances for increased production of renewable energy but it seems that the South-African government suffers from the same failure of imagination as most Western governments: they can't imagine that energy can be produced without burning something, so they aren't encouraging renewable energy as much as it would be possible and advisable. And that's especially bad because South Africa provides energy for several other African countries and it is probably the only country of the region having sufficient resources for an energy transition. A decline in the South African production would reverberate all over the Southern African region.

Then, there is the enormous question of climate change: what's going to happen to Africa as we climb the temperature ladder? We don't really know: some regions of the continent may become too hot for human habitation. The precipitation patterns might change: Cape Town had already a close call with a climate-related disaster with the drought that lasted until 2018.

Fortunately, the abundant rains of 2018 staved off the crisis, but Cape Town went close to be the first modern city in the world that could literally run out of water: it would have been the event known as "day zero,"  the day when nothing would come out of the taps anymore. Was it a problem related to climate change? And will the problem return in the future? We don't know and we can't know, but a future "water apocalypse" for Cape Town cannot be ruled out.

And finally, there is the question of population. In South Africa, the growth rate is slowing down, but the population curve shows no evidence of a flattening trend. At nearly 60 million people, today, it maintains a rate of increase of about 1.5% yearly. It is the inertia of a young population, compounded with legal and illegal immigration. And the economy is not expanding to match the trend: there are ominous signs not only of decline but of a much worse outcome that could include a social collapse undermining the reconciliation policies that had been successful in the 1990s.

Facing these enormous problems, it is no wonder that the Club of Rome has no miracle solution. Perhaps no solution whatsoever. Perhaps nobody in the world has solutions. What the Club could do was to state with the maximum possible force that we are in a climate emergency and that we need to go ahead with a climate emergency plan. Yet, at the meeting in Cape Town, some talks were so removed with the reality of the emergency situation to make one feel like screaming in rage. It takes time for some concepts to penetrate into people's consciousness. Climate change is such a gigantic thing that many people simply can't perceive it. It takes time. Likely, more time than we have.

One thing is clear, anyway, that whatever it is going to happen, we have no hope to do anything unless we do it together as that nebulous entity we call "humankind." We have created the problem, we are the only entity that (perhaps) can solve it. In this sense, the Cape Town meeting was in the best tradition of the Club of Rome as it was established by its founder, Aurelio Peccei. A truly international encounter of people who came from all over the world to bring their contribution and their ideas for the benefit of all humankind. Alone, the Club can't do that much but ideas can grow and spread and there is still hope. In this, Africans could give a major contribution.

So, where are we going? Onward, fellow humans!




(*) I am saddened to have to report that Manphela Raphele received the news of the death of a close family member just at the beginning of the meeting, so that she had to leave. Her presence was sorely missed and I can only offer my sincere condolences to her. Hopefully, she'll be soon active again with the many activities of the Club. 

(**) Greta Thunberg has been able to popularize the concept that flying on a plane is inherently something evil. She is probably right and I have been thinking of that when I considered whether it was a good idea for me to fly to Cape Town. In the end, I decided to do that and I'll see to explain the reasons in a future post.

"The Limits to Growth" continues to make waves



The Club of Rome is holding its annual meeting in Cape Town, South Africa. In the image, you see the co-president, Sandrine Dixon-Decleve, speaking
Now heading toward its 50th anniversary, "The Limits to Growth," the 1972 study sponsored by the Club of Rome, continues to generate interest. Past is the time of the "Limits-Bashing" fashion, when no one would dream to cite the study except to say that it was wrong. But there are still plenty of people who blindly repeat the legend that the study had predicted shortages that never occurred. As Daniel Dennett said, we are apes infested with memes and the Limits to Growth is an especially virulent one. 

Here, Marc Cirigliano writes a balanced review of the story, citing my book on the subject and giving some credit to one of the main critics of the study, Julian Simon, who in my opinion would deserve some more bashing but I admit that he may have been, at least, well-intentioned. 


 

By Marc A. Cirigliano

Popular journalism seems to have finally caught up with what the scientists have been telling us for well over five decades about the environment. You really can’t read anything in mainstream news or commentary without coming across articles about such ecological matters as overpopulation, pollution, resource use and climate change. The main topics related to these stresses include human excesses, noticeable changes that affect the day-to-day well-functioning of a society somewhere on the planet or the long-term viability of human life as we now know it.

It has not been an easy matter for science to get to the point where environmental problems are part of the grist of everyday reporting and opinion pieces. The opposition has been fierce, well funded and plays upon people’s primal fears.

Science discovers new ways of thinking about the world. Often, this is unsettling because with a new way of thinking, there comes change, and, with change, comes the possibility of loss. Sometimes the threat of loss may seem monumental, overwhelming, and, perhaps, even apocalyptic.

Change may portend personal dislocation, social change and economic upheaval. No wonder, then, that some people may see some aspects of scientific advancement as a threat. Further, people in authority may feel that a new scientific discovery threatens their very position of power within society.

One historic centuries old example is religion’s well-known and consistent opposition to a scientific explanation for the universe that upended the Christian one. Science told us the Earth was no longer the center of a God-designed universe. To threaten religion’s primacy even more, evolution upended the hexplanation that humans descended from Adam and Eve. In place of that, science said we descended from other life forms.

Religion freaked out even as the evidence mounted that science was correct.

Still today some clerics defend their authority over parishioners by still insisting the Bible is the undeniable authority in understanding the functioning of the universe, the origin of humans and the motive of humans in living on the planet. Some use it as a reason to oppose environmental reforms all together. Looking at the idea that informs the Abrahamic religions of Judaism, Christianity and Islam, Genesis 1:26 (NIV) gives use the dominion argument:

Then God said, “Let us make mankind in our image, in our likeness, so that they may rule over the fish in the sea and the birds in the sky, over the livestock and all the wild animals, and over all the creatures that move along the ground.”

Yes, the dominion argument is that God sanctioned humanity with using the earth as we see fit. Enironmental science puts forth a different view.We will come back to science as a threat to the authority of the status quo later.

A Major Environmental Warning from 1972


By the 1960s, science had established, or more precisely, environmental science had developed a proven explanation for the complex way ecosystem earth functioned. This explanation used the idea of population dynamics. Here, population growth, carrying capacity, overpopulation and population collapse—also referred to as a die-off or crash—were part of a pattern of life both in a segment of the environment or even on the planet as a whole. Bear in mind that as science developed its ideas on population dynamics, earth was in the midst of a population explosion never before seen.

In 1972, the Club of Rome received a report they had commissioned from four MIT researchers— Donella H. Meadows, Dennis L. Meadows, Jørgen Randers and William W. Behrens III—to study what they called the predicament of mankind. This team published The Limits to Growth (LTG), subtitled A Report for the Club of Rome’s Project on the Predicament of Mankind.

The researchers described their goal and the predicament they were proposing we fix:
The intent of the project is to examine the complex of problems troubling men of all nations: poverty in the midst of plenty; degradation of the environment; loss of faith in institutions; uncontrolled urban spread; insecurity of employment; alienation of youth; rejection of traditional values; and inflation and other monetary and economic disruptions. (10)
The LTG supplied a new way of looking at these problems, problems they labeled as the world problematique:

It is the predicament of mankind that man can perceive the problematique, yet, despite his considerable knowledge and skills, he does not understand the origins, significance, and interrelationships of its many components and thus is unable to devise effective responses. This failure occurs in large part because we continue to examine single items in the problematique without understanding that the whole is more than the sum of its parts, that change in one element means change in the others. (11)
In other words, each of these elements—poverty, environmental loss, social mistrust, overpopulation, job loss, alienated youth, etc.—is part of a system, with system defined as “a regularly interacting or interdependent group of items forming a unified whole.”

Consequently, instead of studying each of these problems separately from the system, the LTG proposed to study them as part of an environmental system. The way they examined this as a system was to develop a model, which they clarified as “simply an ordered set of assumptions about a complex system.” (20)

This was a new approach at that time in 1972.

Let us look at some of the specifics. TLG clarifies:

Our world model was built specifically to investigate five major trends of global concern-accelerating industrialization, rapid population growth, widespread malnutrition, depletion of nonrenewable resources, and a deteriorating environment. (21

The TLG draws a distinction between their approach and more traditional ones:

The model we have constructed is, like every other model, imperfect, oversimplified, and unfinished. We are well aware of its shortcomings, but we believe that it is the most useful model now available for dealing with problems far out on the space-time graph. To our knowledge it is the only formal model in existence that is truly global in scope, that has a time horizon longer than thirty years, and that includes important variables such as population, food production, and pollution, not as independent entities, but as dynamically interacting elements, as they are in the real world. (21-22)

TLG gives us three observations on how we may address these problems:

The present growth trends in world population, industrialization, pollution, food production, and resource depletion continue unchanged, the limits to growth on this planet will be reached sometime within the next one hundred years. The most probable result will be a rather sudden and uncontrollable decline inf both population and industrial capacity.  t is possible to alter these growth trends and to establish a condition of ecological and economic stability that is sustainable far into the future. The state of global equilibrium could be designed so that the basic material needs of each person on earth are satisfied and each person has an equal opportunity to realize his individual human potential. If the world's people decide to strive for this second outcome rather than the first, the sooner they begin working to attain it, the greater will be their chances of success. (23-24) TLG also acknowledges:
These conclusions are so far-reaching and raise so many questions for further study that we are quite frankly overwhelmed by the enormity of the job that must be done. (24)Addressing population growth, TLG zeroes in one of the reasons for the exponential population explosion in the 20th century:
With the spread of modern medicine, public health techniques, and new methods of growing and distributing foods, death rates have fallen around the world. World average life expectancy is currently about 53 years and still rising. On a world average the gain around the positive feedback loop (fertility) has decreased only slightly while the gain around the negative feedback. loop (mortality) is decreasing. The result is an increasing dominance of the positive feedback loop … (37)

In other words, several elements of the world system have enabled the population to grow exponentially. LTG explains further:

The exponential growth of demand for food results directly from the positive feedback loop that is now determining the growth of human population. The supply of food to be expected in the future is dependent on land and fresh water and also on agricultural capital, which depends in turn on the other dominant positive feedback loop in the system-the capital investment loop. Opening new land, farming the sea, or expanding use of fertilizers and pesticides will require an increase of the capital stock devoted to food production. The resources that permit growth of that capital stock tend not to be renewable resources, like land or water, but nonrenewable resources, like fuels or metals. Thus the expansion of food production in the future is very much dependent on the availability of nonrenewable resources. Are there limits to the earth's supply of these resources? (54)

One of the results of population growth caused by resource us is pollution. LTG points out:

Man's concern for the effect of his activities on the natural environment is only very recent. Scientific attempts to measure this effect are even more recent and still very incomplete. We are certainly not able, at this time, to come to any final conclusion about the earth's capacity to absorb pollution. We can, however, make four basic points in this section, which illustrate, from a dynamic, global perspective, how difficult it will be to understand and control the future state of our ecological systems. These points are: 1. The few kinds of pollution that actually have been measured over time seem to be increasing exponentially. 2. We have almost no knowledge about where the upper limits to these pollution growth curves might be. 3. The presence of natural delays in ecological processes increases the probability of underestimating the control measures necessary, and therefore of inadvertently reaching those upper limits. 4. Many pollutants are globally distributed; their harmful effects appear long distances from their points of generation. (69)

There is no doubt today that the deleterious effects of pollution are everywhere: the air, the water and the soil, all in the form of billions of tons of solid waste. All this not only affects people, but also animals, plants and, on a microscopic level, bacteria and viruses. In a simple overview of the systemic nature of the problematique, TLG links these issues together:
Of course, none of the five factors we are examining here is independent. Each interacts constantly with all the others. We have already mentioned some of these interactions. Population cannot grow without food, food production is increased by growth of capital, more capital requires more resources, discarded resources become pollution, pollution interferes with the growth of both population and food. (89)


The Crux of the Matter: “A Choice of Limits”

The heart of the problem has to do with the way that we solve social problems:

But the relationship between the earth's limits and man's activities is changing. The exponential growth curves are adding millions of people and billions of tons of pollutants to the ecosystem each year. Even the ocean, which once appeared virtually inexhaustible, is losing species after species of its commercially useful animals. (151)

After demonstrating the crisis facing the whaling industry around 1972, TLG points out that there were agreed upon limits to whaling to preserve the whale population. By extension, then, the report argues:

The basic choice that faces the whaling industry is the same one that faces any society trying to overcome a natural limit with a new technology. Is it better to try to live within that limit by accepting a self-imposed restriction on growth? Or is it preferable to go on growing until some other natural limit arises, in the hope that at that time another technological leap will allow growth to continue still longer? For the last several hundred years human society has followed the second course so consistently and successfully that the first choice has been all but forgotten. (151-153)

TLG make a point that they:

… are searching for a model output that represents a world system that is: 1. sustainable without sudden and uncontrollable collapse; and 2. capable of satisfying the basic material requirements of all of its people. (158)

To achieve a stable population, the number of births would more or less have to equal the number of deaths. TLG states:
Such a requirement, which is as mathematically simple as it is socially complicated, is for our purposes an experimental device, not necessarily a political recommendation. (159-160)

At the same that TLG discusses socially complicated limits, they acknowledge that:

Technological advance would be both necessary and welcome in the equilibrium state. A few obvious examples of the kinds of practical discoveries that would enhance the workings of a steady state society include:
  • new methods of waste collection, to decrease pollution and make discarded material available for recycling;
  • more efficient techniques of recycling, to reduce rates of resource depletion;
  • better product design to increase product lifetime and promote easy repair, so that the capital depreciation rate would be minimized;
  • harnessing of incident solar energy, the most pollution-free power source;
  • methods of natural pest control, based on more complete understanding of ecological interrelationships;
  • medical advances that would decrease the death rate;
  • contraceptive advances that would facilitate the equalization of the birth rate with the decreasing death rate.

TLG continues:

As for the incentive that would encourage men to produce such technological advances, what better incentive could there be than the knowledge that a new idea would be translated into a visible improvement in the quality of life?

They clarify the social reality of new inventions through history:

Historically mankind's long record of new inventions has resulted in crowding, deterioration of the environment, and greater social inequality because greater productivity has been absorbed by population and capital growth. There is no reason why higher productivity could not be translated into a higher standard of living or more leisure or more pleasant surroundings for everyone, if these goals replace growth as the primary value of society. (177-178)

TLG concludes:

If there is cause for deep concern, there is also cause for hope. Deliberately limiting growth would be difficult, but not impossible. The way to proceed is clear, and the necessary steps, although they are new ones for human society, are well within human capabilities. Man possesses, for a small moment in his history, the most powerful combination of knowledge, tools, and resources the world has ever known. He has all that is physically necessary to create a totally new form of human society-one that would be built to last for generations. The two missing ingredients are a realistic, long-term goal that can guide mankind to the equilibrium society and the human will to achieve that goal. Without such a goal and a commitment to it, short-term concerns will generate the exponential growth that drives the world system toward the limits of the earth and ultimate collapse. With that goal and that commitment, mankind would be ready now to begin a controlled, orderly transition from growth to global equilibrium. (183-184)


Why the Attacks on Limits in Particular and Environmentalism in General?


The Limits to Growth received strong criticism after its publication. It came in many forms. The Limits to Growth threatened specific groups. As Ugo Bardi explains:

In 1997, the Italian economist Giorgio Nebbia, noted that the reaction against the LTG study had arrived from at least four different fronts. One was from those who saw the book as a threat to the growth of their businesses and industries. A second set was that of professional economists, who saw LTG as a threat to their dominance in advising on economic matters. The Catholic world provided further ammunition for the critics, being piqued at the suggestion that overpopulation was one of the major causes of the problems. Then, the political left in the Western World saw the LTG study as a scam of the ruling class, designed to trick workers into believing that the proletarian paradise was not a practical goal. And this by Nebbia is a clearly incomplete list; forgetting religious fundamentalists, the political right, the believers in infinite growth, politicians seeking for easy solutions to all problems and many others.

So, when Limits came out, no doubt that business, industry, economists, religion, politicians, true believers in capitalism, and even workers thought that limiting growth would diminish their respective claims to authority and, most certainly, their lifestyle. This certainly fits, as asserted earlier in this article, that science is a threat to the authority of the status quo.


One Persistent Critic


Although there were many critics and criticisms, one of the most cogent and insistent came from economist Julian Simon. For example, Simon, in his 1995 Cato Policy Report “The State of Humanity: Steadily Improving,” continued his by then multi-decade rejection of the idea of limits to growth by asserting that [Italics added]:

We have seen extraordinary progress for the human enterprise, especially in the past two centuries. Yet many people believe that conditions of life are generally worse than in the past, rather than better.

I must say that nowhere in any environmental studies have I found that assertion, that “conditions of life are generally worse than in the past, rather than better.” Simon is setting this up as a straw man argument, which he easily demolishes with evidence on the improved living conditions of millions, if not billions, of people in our modern age.


In point of fact, these are ideas that TLG agrees with:

With the spread of modern medicine, public health techniques, and new methods of growing and distributing foods, death rates have fallen around the world. World average life expectancy is currently about 53 years and still rising. (37)

Hence, no sensible person, scientist or not, would assert what Simon claims they are asserting. In point of fact, the LTG was quite clear in stating that problems from overpopulation and pollution, plus potential shortfalls of resources, would become paramount well into the future:

…the limits to growth on this planet will be reached sometime within the next one hundred years. (23)
So, LTG is talking about 100 years from 1972, not as Simon claims. And, LTG does not assert, as Simon says they do, that that life is worse now than in the past. However, this is not to entirely dismiss what Simon says. He does develop a provocative thesis when he writes:

The most extraordinary part of the resource-creation process is that temporary or expected shortages -- whether due to population growth, income growth, or other causes -- tend to leave us even better off than if the shortages had never arisen, because of the continuing benefit of the intellectual and physical capital created to meet the shortage. It has been true in the past, and therefore it is likely to be true in the future, that we not only need to solve our problems, but we need the problems imposed upon us by the growth of population and income.

Simon clarifies why he thinks increased population is a benefit to mankind:

The most important benefit of population size and growth is the increase it brings to the stock of useful knowledge. Minds matter economically as much as, or more than, hands or mouths. Progress is limited largely by the availability of trained workers. The main fuel to speed the world's progress is the stock of human knowledge. And the ultimate resource is skilled, spirited, hopeful people, exerting their wills and imaginations to provide for themselves and their families, thereby inevitably contributing to the benefit of everyone.

Simon argues that over the long haul things would continue to get better just as they had been doing for the past two centuries:

The process operates as follows: More people and increased income cause problems in the short run--shortages and pollutions. Short-run scarcity raises prices and pollution causes outcries. Those problems present opportunity and prompt the search for solutions. In a free society solutions are eventually found, though many people seek and fail to find solutions at cost to themselves. In the long run the new developments leave us better off than if the problems had not arisen. This theory fits the facts of history.

This is actually fascinating, because when Simon writes that when things go bad, “those problems present opportunity and prompt the search for solutions,” he actually sounds like an environmentalist. And, he would seem to agree with LTG which says “technological advance would be both necessary and welcome...”


On another point, Simon misses the mark when he claims “there is little scientific literature on the relation of population to war.” Actually, according to Steven A. LeBlanc, there is sound evidence that “ecology and warfare intertwined today, just as they have been for millions of years.” LeBlanc explains:

The consequences of environmental stress will be scarce resources, and the consequences of scarce resources will be warfare. (Constant Battles, 12)

Simon, though, seems to go off his rocker in further explaining the need for and the capacity to invent solutions:

We have in our hands now--actually, in our libraries--the technology to feed, clothe, and supply energy to an ever-growing population for the next 7 billion years.
No doubt we do have the technology through knowledge in our libraries, but, 7 billion years? A bit of an exaggeration, perhaps.


Simon presents his argument as a universal for the ages, that we could apply his assertions to when he was writing, to 7 billion years in the future and to our now of 2019. As such, he would, at least up to now, be wrong. There is no indication that we have policy solutions to our current woes of overpopulation, seemingly insidious pollution (such as Roundup causing cancer, CO2 driving global warming or plastic refuse overwhelming both land and sea), and stresses over resource shortages, such as a lack of arable land and lack of water from droughts.


In fact, the very business and technical community that is creating the progress supporting our modern lifestyle is actually doing the opposite of Simon’s prediction that environmental problems would “prompt the search for solutions.” Business, in general, consistently lobbies against environmental action that effectively stops our politicians from taking any meaningful action. As we see today, President Trump is actually repealing environmental regulations.


Conclusion


The Limits to Growth raised key environmental concerns about population growth, pollution, depletion of resources and a deteriorating environment. These were ideas new to the public and new to policy makers in 1972. Today in 2019 they are foundational concepts in biology, ecology and environmental studies. The MIT researchers who wrote TLG studied these problems as part of an ecological system, not, in the then traditional way as isolated events. To top it off, we were given sound policy advice fifty years ago. Instead of listening, we tried to kill the messenger. To this day, it is advice ignored by policy makers.
