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.

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:

Additional posts definitely worth reading as we enter 2013 are below.

"Why Smart People Are Stupid" and Other Revelations About the Brain

UPDATE 6/24: I cited Jonah Lehrer below. This has to be read to be believed - Lehrer might as well have titled his article about himself.

One of the best books that I read recently is Nobel Prize winner Daniel Kahneman's "Thinking, Fast and Slow". You'll find a lot of reviews of the book online (e.g., Jim Holt at the NYT), but the best thing to do would be to pick up a copy of the book and read it (Sci Am has reprinted a portion recently). As one of the reviewers in Amazon.com, Adam Smythe, wrote [all bold text in this post is my emphasis]:

Daniel Kahneman, the author of this exceptional book, and Amos Tversky (who died in 1996) made economics and other disciplines a lot more realistic--and tougher--for economists, researchers and students. Prior to their work, economists and others maintained classical theories and explanations that relied on certain seemingly logical assumptions about human behavior. However, people don't always behave the way logic might suggest, for a variety of reasons that Kahneman (and Tversky) explained, starting in the 1970s. Today, the subject of behavioral decision-making is one of the more exciting ones in fields like economics, finance, medicine and even law, thanks to their pioneering work. In recognition of the impact of his work in economics, Kahneman, a cognitive psychologist and professor emeritus at Princeton, won the Nobel Prize in Economics in 2002, specifically for his work on prospect theory.

The title of this book comes from Kahneman's discussion of two simple models of how people think. "System 1" thinking corresponds to fast, intuitive, emotional and almost automatic decisions, though it sometimes leaves us at the mercy of our human biases. "System 2" thinking is more slow-going and requires more intellectual effort. To nobody's surprise, we humans are more likely to rely on System 1 thinking, because it saves us effort, even if it can lead to flawed thinking.

Andrew Revkin at Dot Earth (NYT) posted the video a recent talk by Kahneman and added:

As I noted via Twitter during the meeting, this talk and many other engaging presentations at the event illustrate the importance of adding a fresh facet to the popular notion that today’s citizens, and particularly students, would do well to improve their capacity for critical thinking:

“Critical thinking has to include assessing one’s own thinking.”

Last week, Jonah Lehrer at The New Yorker, mentioned Kahneman's work and wrote about another recent study whose implications are important in a post titled "Why Smart People are Stupid". Here are some relevant extracts from Lehrer's piece, but go read his entire post:

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.

Age, Entrepreneurship and Success

Vivek Wadhwa is an Indian-American entrepreneur and academic who writes frequently, and often brashly, on the topic of innovation. I've always found his observations to be thought-provoking. His latest piece in the Washington Post is particularly so:

The case for old entrepreneurs

His article challenges an observation by well-known venture capitalist Vinod Khosla (of Khosla Ventures) on some of Khosla's comments at NASSCOM (see video). Here is the introductory portion of Wadhwa's article [all use of bold text in this post is mine - it's used for emphasis]:

“People under 35 are the people who make change happen,” said venture capitalist Vinod Khosla, “People over 45 basically die in terms of new ideas.”

Khosla, who believes that old entrepreneurs can’t innovate because they keep “falling back on old habits,” said this at the NASSCOM Product Enclave in Bangalore, on Nov. 9.

He isn’t alone in his views.

Silicon Valley VCs talk openly about their bias toward young entrepreneurs. Some argue that Internet entrepreneurs peak at the age of 25.

Khosla and those who think like him are wrong.

This topic is of great interest to me - not so much the question of age of entrepreneurs, but the question of what it takes to build companies that have exemplary long-term success. So, I'll use Wadhwa's article as a pivot to explore a few related aspects and then cite specific examples from the history of companies like Microsoft, Google, Apple and Sun Microsystems to make my case that long-term success takes a lot more than youth or ideas - it requires a level of experience and discipline that understands how to translate ideas into sustainable and lasting success.

1) Wadhwa's observations

Wadhwa cites various studies and data sets that make his case - i.e., older people are not only more likely to start new companies than younger people, they are more likely to be part of successful companies. One of the research papers he cites from his own team is this one: "Education and Tech Entrepreneurship". Here is the abstract of that study:

Together, these strategies could double food production while greatly reducing the environmental impacts of agriculture."
