The Education of a Scientist
h/t Azimuth. See also my previous post on this subject. This clip is lovely when the little bear compares scientific editors to the Sopranos. I signed the petition to boycott Elsevier and I already sent back to them the request for a review that they asked me to do for one of their journals with a note saying "sorry, will not do this because I am boycotting you". I don't know how happy they were about that. I was.

The tin miners
Tin Miners in England. A 1939 painting by Harold Harvey (1874-1941). Image from Bonhams art auctions.
There are very few paintings of miners at work. The dark and cramped world of mines was not accessible to painters and probably it wasn't even interesting for them. There are just a few exceptions; one is the painting above, made by Harold Harwey, a painter from Cornwall who was interested in the local life and the local characters.
The two miners in the painting have names: Sidney Angrove (left) and Nicholas Grenfell (right) (as reported by Bohhams). The painter shows the miners in a moment of relax; while one of the two smokes a pipe. There is no hint of the hard work in the tunnels, below, but the image is nevertheless permeated of a certain melancholy. It was a world that was already in decline when the painting was made, in 1939.
It is in Southern England that we can find the earliest mines in the world. 10,000 years ago there were already mines where ancient miners laboriously broke the fine limestone that we call chalk with deer antlers to seek for ochre and flint. Today, the ancient tunnels dug at that time still exist, we can still see the smoke left by the miners' oil lamps and find the tools left by them. In some tunnels, we can find human skeletons; perhaps miners surprised by a collapse or, maybe, sacrifices to the divinities of the depth.
Mining tin in Cornwall is somewhat more recent, but it still goes back to about 2000 BCE. It continued for millennia, throughout the 20th century. The last tin mine in Cornwall (also the last working tin mine in Europe), was closed in 1998. There is an old Cornish ballad, reported in wikipedia that goes "Cornish lads are fishermen and Cornish lads are miners too. / But when the fish and tin are gone, what are the Cornish boys to do?"
Slowly, we are emptying the Earth of its mineral treasures. Then, what will we do?
h/t to my wife Grazia for the image of the tin miners

Peak? What peak? King coal is coming back!
King Coal may be coming back to save us from peak oil, but condemning us to a worse fate in terms of global warming (image from the National Media Museum)
Recently, Rembrandt Koppelaar has published on the Oil Drum a summary of the world's trends in energy production. The report tells us that the oil industry is struggling to maintain the present levels of production. It may not have peaked yet, but clearly it can't resume the past trends of increase. That's not surprising, it had been foreseen already in 1998 by Colin Campbell and Jean Laherrere (link). What's striking, instead, is the leap forward of coal. The world's total energy production is not peaking and that's because of the rapid growth of coal, as you can see here, from Koppelaar's report:
Coal seemed to have peaked in 1990, but it was an illusion. The growth of coal production during the first decade of the 21st century has been impressive; never seen before in history. So, King Coal is coming back and he may soon reclaim the title of ruler of the energy world that it had lost to crude oil in the 1960s.
We are not seeing anything like a tendency to peak for coal and that, unfortunately, is not good for climate. We can see that from the "other side" of the chemical reaction that sees fossil fuels transformed into carbon dioxide, CO2, whose concentration in the atmosphere is increasing faster in recent times. (the figure below is from "think progress," see also this previous post).
We cannot say that the burst of carbon dioxide that we are seeing is due to coal alone, but it corresponds well to the spike in coal production and it is surely related to it. The global climate situation seems to be rapidly going out of control and this rapid increase in CO2 concentrations doesn't bode well for the future. Bowing down our heads again to King Coal may turn out to be the worst choice we ever made in history.

Defending good science: Michael Mann speaks out
Michael Mann is the author of the "hockey stick" reconstruction that shows how the past decades have been anomalously hot as the result of global warming. In this video, he tells us of his experience, of the ordeal he has gone through, and that he is still experiencing, attacked by professionals of public relations who have unleashed a full propaganda campaign against him. Mann has been harassed and denigrated in all possible ways, including death threats to him and to his family. We need to resist against the forces who are trying to destroy climate science and science in general. Michael Mann, defined "Battle Hardened" in this clip, is doing that, and he is succeeding, but he needs all the help and support we can give to him. We all need to speak out against the forces of anti-science!

"Peak Research:" Italian researchers do it doggy style, in a tunnel
Copy of an announcement in "Nature Jobs," as it appeared yesterday, for a research project managed by the University of Florence. This page has been subsequently removed, but the stain on the reputation of Italian research remains.
This story is doing the rounds in the Italian web. Our Ministry of research (MIUR) had published on their site the translation of the title of a European Research project dedicated to cheese. The cheese they study is called "pecorino" (literally "sheep-cheese") which has a certain assonance with the term used in Italian ("pecorina") for what in English is called "doggy style". Now, some idiot translated it exactly that way: "doggy style"! For a while, that translation was featured also on the "Nature" web site. Later on, it was removed from both pages, but you can still read it for your amusement in the picture above (see also below and here)
All that is on a par with the story of the "neutrino tunnel", also from our ministry of research where, among other idiocies, it was said that neutrinos generated in Switzerland would travel in a tunnel all the way to Italy. You can read about this story here.
This epic fail of MIUR may be a little off topic for the "Cassandra" blog, but perhaps not so much. If nothing else, it shows how rapidly a university system can decay when it is left with no attention and no money. Maybe Italy is on the forefront in the world in terms of decadence, but I am sure that all countries have the same problem: how to sustain their research and university teaching systems with declining resources. It is, in the end, another symptom of the effects of having overexploited our resources. We passed the peak in many areas, we should not be surprised to be seeing also "Peak Research"
Here is also, conserved for posterity, the announcement as it appeared on the Italian ministry of research (MIUR) web site
And also here on the site of the European Commission

The seekers effect: why we keep seeking growth at all costs
Already in 1972, the classic study "The Limits to Growth" had shown that economic growth could not last forever (above: the "base case" scenario from the study). Even without complex calculations, it should be clear from simple physics that infinite growth is not possible in a finite world. Yet, politicians, leaders, economists, decision makers and the like are all pushing for growth, growth, and more growth. In an earlier post, I tried to find rational reasons for this attitude, but I tend to think that it can be better explained in terms of the "Seekers effect." The term comes from the name of an esoteric sect, the "Seekers" active in the 1950s who believed to have been alerted by aliens of the incoming end of the world.
If you are trained in science or engineering, you probably think that your views should be based on the available data and that, if better data become available, then you should change your views. You may think that this is the obvious way to behave, but think twice. Most likely, you are part of a minority; possibly a tiny minority. By far, most people seem to act on a different set of principles. They will normally stick to their opinion no matter what the data say. And if new data contradict a previous held opinion, the hell with the new data. It is something that we could call the "Seekers effect."
The Seekers were an esoteric sect active in the 1950s. A summary of their story is told by Chris Money in an article titled "The science of why we don't believe in science." In short, the Seekers had gathered around a lady named Dorothy Martin who was claiming to be receiving telepathic messages from aliens. She had been told that a major cataclysmic event would take place on a specific date: December 21, 1954. Most of humankind would be destroyed; but the Seekers themselves would be taken to safety on an alien spaceship landing on that day.
The special element that makes the Seekers a paradigm in human behavior is that they had been infiltrated by a group of social psychologists, led by Leon Festinger, who watched them until and after the fated date when, obviously, no catastrophe occurred. In Festinger's 1956 book "When Prophecy Fails" we can read how the seekers reacted to the failure of their leader's prophecy. Their first reaction, of course, was of dismay. But that didn't last long. In a few days, the Seekers had closed ranks and restructured their beliefs: their prophet, ms. Martin had not been wrong at all; the aliens had decided to spare humankind as the result of the faith of the Seekers! The most interesting twist in this story is that not only the seekers didn't accept that their prophecies were wrong; they stepped up efforts to recruit new followers and to convince everyone of their ideas. Eventually, the were ridiculed so much that they disappeared, but that took a few years.
The story of the Seekers is one of the best studied of what is called "motivated reasoning"; that is the tendency of twisting facts and logic in order keep one's beloved worldview. Money says that:
We're not driven only by emotions, of course—we also reason, deliberate. But reasoning comes later, works slower—and even then, it doesn't take place in an emotional vacuum. Rather, our quick-fire emotions can set us on a course of thinking that's highly biased, especially on topics we care a great deal about... we have other important goals besides accuracy—including identity affirmation and protecting one's sense of self—and often those make us highly resistant to changing our beliefs when the facts say we should.
Motivated reasoning is very common. Today, you don't need to infiltrate any esoteric sect to see it at work: you can see dramas similar to the one of the Seekers unfolding on discussion sites and on Facebook. A recent case in point is that of the "E-Cat", the fabulous nuclear device that should have brought us eternal prosperity. Give a look to some of the sites of the believers and you'll see that, despite the accumulation of proof that the E-Cat is nothing but a glorified teapot, the believers are unmoved in their stance. Not just that, but are also doubling up their efforts to convince everyone that their teapot is, really, a nuclear reactor.
Most of the discussions that take place on the Web, say, on climate, energy, peak oil and the like, are not based on data or logic; have you ever seen anyone changing his/her opinion in one of these discussions? Maybe it happens, sometimes, but it is almost a miraculous event.
The same motivated reasoning seems to be at work on economic growth. It takes place mostly on the media, rather than on the web, but the psychological factors at play seem to be the same. So, it is growth, growth and more growth; it is always the same concept, repeated over and over in the media. Yet, there is no rational reason (even though I tried to find one) for choosing growth over every other possible strategy. It is our tendency to stick to our previous beliefs. In the past, we put so much effort in the belief that growth can cure all ills, that now we cannot back up without losing face. It is the Seekers effect.

Long live the hockey stick! Climate science fights back.
The new book by Michael Mann tells the story of the reconstruction of past temperatures called "the hockey stick" because of its characteristic shape. Despite the propaganda campaign against climate science, climate scientists are standing their ground and fighting back.
Repeat something a sufficient number of times and, eventually, people will believe it, no matter whether it is true or not. It is one of the most effective tricks of propaganda and it has been used more than once against science, for instance in the demonization of the "Limits to Growth" study. During the past few years, it has been applied repeatedly, even obsessively, against the "hockey stick," the reconstruction of past temperatures on which Michael Mann and coworkers had been working from the 1990s.
It is rare in the history of science that a single piece of experimental evidence has been the object of so many attempts of demolition. Yet, all the serious reviews of the original data have basically confirmed the initial results. Being unsuccessful in demolishing the science, the attacks have moved against the scientist, Michael Mann himself, who has been subjected to an unbelievable denigration campaign, defamed, insulted, and even physically threatened. Recently, the campaign against Mann has targeted his new book, "The Hockey Stick and the Climate Wars", with a large number of negative reviews and derogatory remarks which appeared in the reviews of the book on the Amazon site. Most of these seem to be the work of web identities created expressly for this purpose, i.e. "sock puppets".
What is amazing in this story is how people are fighting back! If you look at the comments on the Amazon site, you see how the derogatory comments have been overwhelmed by favorable comments written by real people who signed with their names. Climate science is still under heavy attack but, clearly, there is a core of concerned people who care about the future. Science is standing its ground and refuses to be overwhelmed by propaganda. It is a difficult battle but we need to fight it for everybody's future.
At this point, it seems appropriate to me to publish on this blog the interview that Michael Mann had granted to Italian version of the "Cassandra" blog in 2010. Here it is, in English.
From "Effetto Cassandra", Sep 05, 2010
1. First of all, can you tell us something of your scientific career? How did you arrive to study tree rings and paleoclimate?
It was a long and circuitous route. I started out as a physicist and had passed my exams and was ready to go on and do Ph.D. research in theoretical physics. But my heart was elsewhere. I wanted to work on something that had more obvious world-world implications. I saw that there were other faculty at the university I was studying at (Yale University) who worked on applications of physics to the geosciences. In particular, there was a professor (Barry Saltzman) who was working on the problem of modeling Earth's climate. that sounded fascinating to me. I went and talked with him, and he agreed to take my on as a student for the summer. That worked out well, and I ended up doing my Ph.D. with him, in the department of geology & geophysics. My Ph.D. involved studying the natural variability of the climate system (i.e. the natural long-term oscillations of the climate) using theoretical climate models and analysis of available observations. The historical record wasn't long enough to study possible century-scale oscillations. That's what originally led me to turn to climate proxy data, such as tree-rings, corals, ice cores, etc. they could provide a longer-term, if more uncertain, perspective on the evolution of Earth's climate over the centuries. Ironically, my original foray into climate proxy data had nothing to do with climate change per se!
2. At some point, you must have realized that the discussion about the validity of the paleoclimate studies had turned from a scientific one to a political one. Can you tell us how and when you discovered that the dispute had stepped outside the limits of the scientific debate?
Well, after our temperature reconstruction (the so-called "Hockey Stick") was featured in the very prominent IPCC summary for policy makers in 2001, we suspected we would be subject to attack by climate change deniers. And they haven't disappointed. Their strategy has always been to attack the messenger, discredit the science and scientists, and fool the public. We've seen this for decades. Its the same playbook that for example the tobacco industry, the chemical industry, and the pharmaceutical industry have all used to try to discredit science demonstrating potential adverse effects from the use of their product. The fossil fuel industry has taken it to a whole other level however. We literally have the most powerful industry that ever existed on earth using much of their resources to smear the science and confuse the public about the adverse effects to our world of fossil fuel burning. History will look back most unkindly on industry-funded individuals and groups who sought to intentionally mislead the public about the reality and threat of human-caused climate change.
3. With the great noise about the "hockey stick" and about "Climategate", many people became convinced - in many cases, I think, in good faith - that you are a liar, a criminal and worse. How does that affect your everyday life? For instance, how about your students?
Well, I like to think that individuals engaged in good faith would think no such thing, as even a cursory examination of the facts demonstrates otherwise. But I do think that there has been such a concerted, well-funded smear campaign against climate science and climate scientists by industry front groups and the far right, that even some reasonable people may be rather confused now about the facts. That of course is the intent of the industry-funded disinformation campaign. Fortunately, I have had much support from my students and colleagues at the University, and scientists around the world, who recognize the smear campaign against me and other climate scientists, for what it is. Of course, there are some ill-informed individuals out there who have engaged in some rather nasty activities, including hateful note and emails, and the like. Unfortunately, its now a fact of life if you're a prominent climate change researcher that you will be subject to these tactics.
4. I think that we - as scientists - must have made some serious mistakes in our communication strategy if deniers have been so successful in attacking climate science. Of course, one of the reasons is that they are led by professional PR people, very good at this kind of campaigns. Yet, I think that the scientific community has neglected communication - would you agree with me on this point? And what do you think we should do in the future to improve our strategy of communication and avoid seeing again such things as Climategate?
Well, I do agree that the scientific community at times has been slow to recognize the concerted, well-funded smear campaign against us and to do something to fight back. In the wake of the manufactured 'climategate' campaign and the attacks against the IPCC, many of my colleagues have now awakened to what we're up against. So perhaps that is the silver lining in all of this. I think in the future you will see far more resources devoted to outreach and communication, including a rapid response strategy to concerted efforts to smear our science and scientists.
5. Scientists often tend to seek public anonymity. They seem to believe that "facts should speak for themselves". Instead, deniers promote themselves as public figures. They may not be nice people, but they know that the message and the messenger cannot be separated and this tactic has been successful. Personally, I believe that this is one of the (very few) things we should learn from them. Do you agree with me? Do you think we should all acquire a better personal visibility?
I do agree. I think we need to humanize the image of the scientist to the public. Too often, scientists are viewed as cold, disconnected, antisocial beings. There are always a few bad apples. But in the vast majority of cases, nothing could be further from the truth. The professional climate change denial campaign has recruited and trained a cadre of charismatic individuals who, though thorough charlatans, are versed in presenting a public face of affability and are quite skilled rhetorically. Scientists are often out-matched when going up against them in debates and other public forums, even though we have objective reality and truthfulness on our side. This problem is now well recognized, and there are many individuals and groups that are trying to deal with it. So I expect much serious efforts to address this problem in the months ahead.
6. Paleoclimatology is a fascinating subject, too bad that it has been so clouded by silly controversies about the "hockey stick". Apart from that; paleoclimatology goes to explore a fundamental point: the relation of human beings with their environment. So, climate change affects humans but also humans change climate. We have plenty of examples in which the collapse of a civilization has been linked to climate change; from the Maya to the Romans, but we still are not able to establish a relation of cause and effect. According to Ruddiman, humans have been affecting climate from the starting of agriculture, but it is also possible that external factors have been at play as well, for instance small changes in the solar output. Of course, this is a field that is still in its infancy, but you are at the forefront of these studies and you could tell us - perhaps - your opinion: do we find a relation between human activity and climate change in the past? Are civilizations brought down by climate change, or do civilizations create the change that destroys them?
Great questions, and I wish I had all of the answers. I think Jared Diamond has perhaps addressed best some of the larger questions here in his book "Collapse". There are many examples we can look to in the past where human's had the ability to exploit and degrade their environment to the point of unsustainability. The destruction of Easter Island through uncontrolled deforestation is one of the great cautionary tales to humanity in this regard. Bill Ruddiman has made a compelling argument that human activity (e.g. rice cultivation and deforestation) might have begun to influence the concentrations of greenhouse gases to the point of having some climate impact several thousand years back. The claim remains rather controversial. What is not controversial is that only within the past century to we have the means at our disposal to change global climate in a dramatic fashion over such a short timescale. It is really the rate at which humans are influencing the climate which poses the greatest threat. Humans and natural ecosystems can adapt to slow change in climate. There is no analog we know of in the past where global climate has been altered as rapidly as we are changing it today. So we are in unchartered waters, engaged in an uncontrolled experiment with the future of civilization and the environment potentially hanging in the balance.
