Fallacies Galore in Ridley's Scarcity Fallacy

A weekend ago, Matt Ridley wrote an engaging piece for the Wall Street Journal that was originally titled "The Scarcity Fallacy" - the title has since changed to "The World's Resources Aren't Running Out". The basic thesis of his essay is this:

Ecologists worry that the world's resources come in fixed amounts that will run out, but we have broken through such limits again and again

In the body of his essay, Ridley says:

Ecologists call this "niche construction"—that people (and indeed some other animals) can create new opportunities for themselves by making their habitats more productive in some way. Agriculture is the classic example of niche construction: We stopped relying on nature's bounty and substituted an artificial and much larger bounty.

Economists call the same phenomenon innovation. What frustrates them about ecologists is the latter's tendency to think in terms of static limits. Ecologists can't seem to see that when whale oil starts to run out, petroleum is discovered, or that when farm yields flatten, fertilizer comes along, or that when glass fiber is invented, demand for copper falls.

...and adds:

I nowadays lean to the view that there are no limits because we can invent new ways of doing more with less.

I tend to generally agree with Ridley's premise that innovation of various kinds has allowed us to extend the use of resources or find alternate ways to meet our needs. I very much share this optimistic view of humanity and future possibilities.

That said, some of the claims in his essay made me wonder how well researched the essay is and how accurately it represents the facts or mainstream views on some of the areas of discussion. Since I write now and then on climate change, I figured I'd pick that as an example to discuss Ridley's essay - sure enough, a quick read of Ridley's claims makes it evident his discussion is amazingly superficial and creates many fallacies of its own in terms of how it represents the scientific/economic thinking on this subject. In fact, I would not be surprised if his discussion of topics other than climate change were likely as superficial and fallacy-ridden, because the last time he wrote on similar subjects in 2012, the claims were problematic to say the least.

Let's start with these two passages in his current essay (I've highlighted some portions in bold text):

This disagreement goes to the heart of many current political issues and explains much about why people disagree about environmental policy. In the climate debate, for example, pessimists see a limit to the atmosphere's capacity to cope with extra carbon dioxide without rapid warming. So a continuing increase in emissions if economic growth continues will eventually accelerate warming to dangerous rates. But optimists see economic growth leading to technological change that would result in the use of lower-carbon energy. That would allow warming to level off long before it does much harm.

It is striking, for example, that the Intergovernmental Panel on Climate Change's recent forecast that temperatures would rise by 3.7 to 4.8 degrees Celsius compared with preindustrial levels by 2100 was based on several assumptions: little technological change, an end to the 50-year fall in population growth rates, a tripling (only) of per capita income and not much improvement in the energy efficiency of the economy. Basically, that would mean a world much like today's but with lots more people burning lots more coal and oil, leading to an increase in emissions. Most economists expect a five- or tenfold increase in income, huge changes in technology and an end to population growth by 2100: not so many more people needing much less carbon.

Dictionary.com defines "fallacy" as follows:

Disaster Costs, GDP and Climate Change

Roger Pielke Jr. recently published an article in Nate Silver's new 538 website titled Disasters Cost More Than Ever But Not Because of Climate Change. You should click the link and read his entire piece but, his thesis is essentially the following:

1. The cost of disasters tied to extreme events is indeed rising rapidly - but once you normalize this to the increase in the wealth of the world as represented by global GDP (we own a lot more "stuff" now than before) - the trend basically vanishes
2. Disasters lead to high loss of life where property damage is the lowest and highest property damage in places with lowest loss of life. As examples he cites the following: "U.S. hurricanes, for example, are responsible for 58 percent of the increase in the property losses in the Munich Re global dataset" and "Consider that since 1940 in the United States 3,322 people have died in 118 hurricanes that made landfall. Last year in a poor region of the Philippines, a single storm, Typhoon Hayain, killed twice as many people."
3. Richer countries are in a better position to protect people's lives in times of disasters at the expense of higher property losses. He says: "As countries become richer, they are better able to deal with disasters — meaning more people are protected and fewer lose their lives. Increased property losses, it turns out, are a price worth paying"

His article was roundly criticized by some well known climate scientists, as summarized by Emily Atkin at Think Progress (additional discussion in this post by Laurence Lewis at Daily Kos). The crux of the criticism as I see it:

1. Improvements to deal with disasters (e.g., newer building codes and improved construction, better forecasting, better preparedness and responses) over the years reduces disaster damages/costs (lives and property) and this is not properly reflected in Pielke's assertions - this has been pointed out to him before, yet he continues to publish his misleading claim
2. Unlike Pielke's claims that somehow climate change is not causing an increasing frequency of extreme events, there are several situations where this is in fact the case

Pielke responded to these critiques in an email to Think Progress (same link as above):

The Hockey Stick and The Climate Wars: A Brief Review and Climate Change Discussion

I recently read Professor Michael Mann's book "The Hockey Stick and The Climate Wars". There are several reviews of the book online, a couple of examples being Shawn Lawrence Otto's review at The Huffington Post and Jeff Masters' review at Wunderground. However, I found the book compelling, engaging and valuable on several fronts and felt it was worth making a few observations here. If you are a person who is not entirely familiar with the recent history and politics of climate science, it offers a highly readable and informative summary that captures some of the progress and setbacks over the last two decades or so. Mann's passion for climate science comes through very well in the book and in the process he also addresses in some detail the following aspects of climate change.

I. Scientific Process, Climate Politics & Denialism

1) The IPCC scientific process and rigor which is quite substantial to the point of making the reports somewhat conservative - despite the seepage of occasional errors into IPCC reports

2) The right role of true skepticism in scientific inquiry - and how this differs from the practice of climate change denial (or climate denial) that uses a combination of (a) a veneer of skepticism, (b) often incompetence in basic statistics and (c) the use of deliberately misleading data

• Mann cites several examples in his book; a perusal of blogs like Deltoid, Skeptical Science, Open Mind and others provides interminable, yet dark, amusement on this front

3) The slow but gradual evolution of scientific knowledge, a process that is self-correcting and generates better understanding over time

• Mann offers many interesting examples from the climate change field contrasting them with the typical demands of the blog/media/news cycle that might immediately trumpet a new research paper as if it almost single-handedly destroyed the scientific consensus, without waiting for the time-intensive scientific process to peer assessment, correction and learning

4) The role of the key players in the fossil-fuels sector - whose future assets, fuel reserves and stock prices are at significant risk if meaningful climate change policy actions are taken - and that of other ideologically aligned wealthy donors in funding climate denialism

5) The deplorable, often personal attacks on climate scientists who publicly speak or write about the serious manifestations and consequences of climate change through willful misrepresentation of their or others' work and/or false accusations of fraud or misconduct

• As Mann shows, these attacks are usually fronted by certain politicians (usually Republicans close to the fossil fuel industry), a handful of scientists who are typically not climate science experts, and often by denialist writers, bloggers and pseudo-scientists. Mann also suggests that the manufactured controversy has often coincided with time periods when the U.S. Congress was poised to pass climate change legislation - thereby making it easier to kill such legislation.
• The attacks and their consequences are examined in much detail given Mann's personal experience and the character assassination campaign he and some of his peers have faced over the years; he particularly explores the controversy over the "hockey stick" and the Climategate episode
• Mann makes reference to another excellent, must-read book on this particular topic - "Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming" by Naomi Oreskes and Eric Conway

6) The increasing use of blogs (e.g., RealClimate) by climate scientists to communicate the science to the public and media, and push back in real time on false, distorted or misleading presentations of climate data

II. Science of Climate Change

7) The role that various natural (e.g., solar activity, volcanoes, various oceanic oscillations that operate over multi-year, decadal, multi-decadal or multi-century periods - such as the multi-year oscillation called ENSO or El-Nino/La Nina) and human-induced/anthropogenic factors (CO₂, sulfur dioxide - SO₂, etc.) play in influencing global warming and climate change

• Mann walks readers through how different factors can affect climate and temperature in different ways, thereby providing a nuanced discussion of climate change and warming, which is often missing or understated in websites arguing against the evidence for anthropogenic global warming

8) The role of temperature proxies - such as tree rings, ice cores, lake sediments, etc. - in the estimation of local, regional and global average temperatures in past centuries and millennia when accurate temperature measurements were not available

• In particular, Mann devotes considerable effort to explain the famous "hockey stick" graph (which has since been independently validated by both the National Academy of Sciences as well as recent work by NOAA's NCDC) and discusses topics such as the so-called Medieval Warm Period, urban-heat island (UHI) effect, and others which play an important role in climate change debates

9) The use of statistical frameworks such as principal component analysis (PCA) in the understanding of underlying phenomena and variables driving temperature changes

Mann's book tries to cover all that and more and does a really nice job overall in giving the reader an expansive view of the nuanced subject of climate change, while passionately conveying the real urgency of acknowledging the dangers of ongoing and future warming and the need for immediate action. I highly recommend this book.

In terms of where the book could have been improved, I would suggest the following thoughts for Mann and other climate scientists to consider. Unless someone is an avid follower of the field of climate change and global warming, it is difficult to grasp the nuances and subtleties inherent in understanding climate, weather and the variables that can cause them to shift. I think Mann's book can be further improved, perhaps in his next edition, by more explicitly delving into common points of confusion for people I have talked to, such as:

• Dueling reports of record heat and record cold (recent examples): This confusion might persist because typical discussions on global warming, even by scientists, fail to adequately inform people that warming refers only to averages and that record heat and cold can co-exist in a warming world as long as record heat events significantly outnumber record cold events as the average temperature rises
• Reports attributing certain seemingly contradictory climatic and meteorological events to global warming (e.g., less snow v. blizzards, flooding v. drought, etc.): It's important that scientists invest more time in developing communication to explain how both droughts and severe flooding could result from warming, that both blizzards and reduced snow can be a consequence of warming, etc.
• Why seemingly modest increases in global temperature (e.g., 0.8 degrees C) should result in significant increases in extreme events: It wasn't until the excellent work of Hansen et al. in 2012 did a clear framework become available to average readers like me to explain to others that a small shift in averages can lead to a large increase in probability of 3-sigma, 4-sigma and beyond temperatures, which in turn can lead to more extreme events over time, relative to past experience
• Lack of clear understanding of the role of additional factors that cause otherwise CO₂-influenced temperature changes to be non-monotonic: The recent work by Skeptical Science is very welcome in this context but it is rare to see scientists use simplified means of communication on such an important topic

Additionally, I would like to urge Mann and his colleagues/peers to invest more time in discussing & explaining the role of the potent greenhouse gas methane (CH₄) and the pros and cons of migrating our energy use from fuels like coal to natural gas, especially given the increasing concerns of methane leakage during natural gas extraction.

Finally, while I very much like blogs like Real Climate, climate scientists need to do a better job of communicating their findings and implications in plain English. Again, Skeptical Science is doing a fantastic job on this and newer initiatives like Climate Communication are welcome and overdue but scientists need to be more tuned to this need going forward.

The Latest on Global Warming and Climate Change

Updated 1/20/13

Here are two new, excellent short videos (about a couple of minutes or so each) that explain (a) how global warming due to anthropogenic greenhouse gases is happening in parallel with natural variability of temperature due to factors such as volcanic eruptions (e.g., El Chichon and Pinatubo) and oceanic oscillations (e.g., El Nino and La Nina) and (b) how the average temperature derived from various paleoclimatic temperature proxies (e.g., ice cores, corals, etc.) are positively correlated with thermometer-based temperature records.

The video explaining natural versus human contributions to climate change is the one below from the outstanding blog Skeptical Science, and discussed in posts such as this one "16 More Years of Global Warming". Also worth reading are related posts from the last couple of years:

• "Why Wasn't The Hottest Decade Hotter?" by Rob Painting at Skeptical Science
• "Resolving Confusion Over the Met Office Statement and Continued Global Warming" by Dana Nuccitelli at Skeptical Science
• "Did global warming stop in 1998, 1995, 2002, 2007, 2010?" at Skeptical Science
• "Video And Charts Make Clear The Planet Is Still Warming — And There’s Only One Way To Stop It" by Joe Romm at Climate Progress

A broad team including several universities and NOAA's National Climatic Data Center (NCDC) just published this paper - Global warming in an independent record of the last 130 years (David Anderson et al.) - in Geophysical Research Letters and a discussion of their paper at the NOAA website - "Independent Evidence Confirms Global Warming in Instrument Record". Skeptical Science also has some analysis and discussion of this paper at "Nature Confirms Global Warming and Temperature Record Accuracy". An additional resource worth reading is this 2006 report by The National Research Council of the National Academies - "Surface Temperature Reconstructions for the Last 2,000 Years".

Here is a short video summarizing the results:

Average Scaling Behavior in Biology, Cities and Corporations

I recently started reading some research from Geoffrey West, Luis Bettencourt and others on scaling phenomena relating to averages (there are always deviations). This is an incredibly rich topic and one cannot possibly do justice to it in a single post, so I'll merely highlight one or two findings from the research and provide links for further reading.

A good place to start is this article on biological organisms in Physics Today from 2004, by Geoffrey West and James Brown - "Life's Universal Scaling Laws". A couple of key passages (all bold text corresponds to my emphasis):

In marked contrast to the amazing diversity and complexity of living organisms is the remarkable simplicity of the scaling behavior of key biological processes over a broad spectrum of phenomena and an immense range of energy and mass. Scaling as a manifestation of underlying dynamics and geometry is familiar throughout physics. It has been instrumental in helping scientists gain deeper insights into problems ranging across the entire spectrum of science and technology, because scaling laws typically reflect underlying generic features and physical principles that are independent of detailed dynamics or specific characteristics of particular models. Phase transitions, chaos, the unification of the fundamental forces of nature, and the discovery of quarks are a few of the more significant examples in which scaling has illuminated important universal principles or structure.

In biology, the observed scaling is typically a simple power law: Y = Y₀M^b, where Y is some observable, Y₀ a constant, and M the mass of the organism.^1-3 Perhaps of even greater significance, the exponent b almost invariably approximates a simple multiple of 1/4. Among the many fundamental variables that obey such scaling laws - termed "allometric" by Julian Huxley⁴ - are metabolic rate, life span, growth rate, heart rate, DNA nucleotide substitution rate, lengths of aortas and genomes, tree height, mass of cerebral grey matter, density of mitochondria, and concentration of RNA.

[...]

An intriguing consequence of these "quarter-power" scaling laws is the emergence of invariant quantities,⁷ which physicists recognize as usually reflecting fundamental underlying constraints. For example, mammalian life span increases as approximately M^1/4,  whereas heart rate decreases as M^-1/4, so the number of heartbeats per lifetime is approximately invariant (about 1.5 x 10⁹), independent of size...

Bettencourt and West discussed cities and their economics and laws of scaling in their article in Scientific American last year titled "Bigger Cities Do More With Less". Here are some notable points:

By sifting through this flood of data, covering thousands of cities around the world, we have unveiled several mathematical “laws” that explain how concentrating people in one place affects economic activity, return on infrastructure investment and social vitality. Despite the rich diversity of metropolitan regions across the U.S., China, Brazil and other nations, we found a remarkable universality in the way that socioeconomic characteristics increase with a city’s population. For example, if the population of a city is doubled, whether from 40,000 to 80,000 or from four million to eight million, we systematically see an average increase of around 15 percent in measures such as wages and patents produced per capita. If eight million people all live in one city, their economic output will typically be about 15 percent greater than if the same eight million people lived in two cities of half the size. We call this effect “superlinear scaling”: the socioeconomic properties of cities increase faster than a direct (or linear) relation to their population would predict.

The data also reveal that cities’ use of resources follows a similar, though inverted, law. When the size of a city doubles, its material infrastructure—anything from the number of gas stations to the total length of its pipes, roads or electrical wires—does not. Instead these quantities rise more slowly than population size: a city of eight million typically needs 15 percent less of the same infrastructure than do two cities of four million each. This pattern is referred to as sublinear scaling. On average, the bigger the city, the more efficient its use of infrastructure, leading to important savings in materials, energy and emissions.

Our findings also show that these patterns of increased productivity and decreased costs hold true across nations with very different levels of development, technology and wealth. Although we have much more information for cities in richer parts of the world, we are beginning to obtain good data from rapidly developing countries as well, and they seem to fit the same mold. The gross domestic product for cities in Brazil and China, for instance, closely follows the same superlinear curve that western European and North American cities exhibit, though starting from a lower baseline. We believe that the pattern holds true because the same basic social and economic processes are at work, whether in São Paulo’s favelas, under Beijing’s smog-filled skies or along Copenhagen’s tidy streets.

Although urban superlinear scaling, which represents the average, idealized behavior of a city of a given size, prevails around the globe, actual cities deviate to varying degrees from the roughly 15 percent enhancements that come with size. Detailed data covering 40 years show, for example, that San Francisco and Boston are richer than their size would indicate, whereas Phoenix or Riverside, Calif., are somewhat poorer. Curiously, these deviations persist for decades: cities tend to stay remarkably close to their overperforming or underperforming histories. For example, cities that have attempted to improve their lot by creating conditions for the “next Silicon Valley” have often had disappointing results. Our research suggests that certain intangible qualities of social dynamics—more than the development of material infrastructure—hold the key to generating virtuous cycles of innovation and creation of wealth. These processes, such as the development of a spirit of local entrepreneurship, a reputation for cutting-edge novelty, and a culture of excellence and competitiveness, are difficult to design through policy because they rely on the dynamics of a city’s social fabric across many dimensions. We expect the results of this exciting area of research will lead to better “recipes” for sustainable socioeconomic development.

See the Physics Today article as well this article for some discussion of West's work, including some of the criticisms of the averages and how they miss various deviations from the averages. A recent paper that critiques the Bettencourt/West research on cities is this one by Cosma Shalizi, who says:

• Mike Konczal at Rortybomb: Comparing the Federal Reserve's Reaction to the Financial Crisis Versus the Unemployment Crisis [Wow!]
  • Konczal says: "To recap: Lehman Brothers goes worse than the Federal Reserve’s projection and the Fed goes to the most extreme lengths it can find to extend emergency lending. Every single unemployment number turns out to be worse than all of the Federal Reserve’s projections, and the Federal Reserve finds every excuse to look the other way. Only Charles Evans has the courage to say that we should let inflation go to 3% while unemployment is over 7% to catch up to trend growth. Amazing."

• Vivek Wadhwa in the Washington Post: Why silicon valley should fear India

On that last article....I agree with much of Wadhwa's observations about India based on my experience - in particular, these passages:

India’s information technology sector may have started by running call centers and maintaining old computer code for American companies. But, today, instead of starting more I.T. services companies, a new breed of Indian entrepreneurs are developing high-value technology products based on intellectual property.

[...]

But something is missing in India: The angel investors, venture capitalists, and, most critically, experienced mentors. This problem will fix itself as more companies achieve success and seasoned entrepreneurs decide to give back to the next generation. When that happens, Silicon Valley better watch out. It is in for some very real competition.
