Green Bootleggers and Baptists - Bjørn Lomborg - Project Syndicate

In May, the United Nations’ International Panel on Climate Change made media waves with a new report on renewable energy. As in the past, the IPCC first issued a short summary; only later would it reveal all of the data. So it was left up to the IPCC’s spin-doctors to present the take-home message for journalists.

The first line of the IPCC’s press release declared, “Close to 80% of the world‘s energy supply could be met by renewables by mid-century if backed by the right enabling public policies.” That story was repeated by media organizations worldwide.

Last month, the IPCC released the full report, together with the data behind this startlingly optimistic claim. Only then did it emerge that it was based solely on the most optimistic of 164 modeling scenarios that researchers investigated. And this single scenario stemmed from a single study that was traced back to a report by the environmental organization Greenpeace. The author of that report – a Greenpeace staff member – was one of the IPCC’s lead authors.

The claim rested on the assumption of a large reduction in global energy use. Given the number of people climbing out of poverty in China and India, that is a deeply implausible scenario.

Green Energy Assumption Model Optimism Poverty Economy

This sort of behavior – with activists and big energy companies uniting to applaud anything that suggests a need for increased subsidies to alternative energy – was famously captured by the so-called “bootleggers and Baptists” theory of politics.

The theory grew out of the experience of the southern United States, where many jurisdictions required stores to close on Sunday, thus preventing the sale of alcohol. The regulation was supported by religious groups for moral reasons, but also by bootleggers, because they had the market to themselves on Sundays. Politicians would adopt the Baptists’ pious rhetoric, while quietly taking campaign contributions from the criminals.
Of course, today’s climate-change “bootleggers” are not engaged in any illegal behavior. But the self-interest of energy companies, biofuel producers, insurance firms, lobbyists, and others in supporting “green” policies is a point that is often missed.

- Dubious claims by faithful activists gave rise to the biofuels industry (with supporting lobbyists). Biofuel production likely increases atmospheric carbon, owing to the massive deforestation that it requires, while crop diversion increases food prices and contributes to global hunger. While environmentalists have started to acknowledge this, the industry received a lot of activist support when it began – and neither agribusiness nor green-energy producers have any interest in changing course now.
- private firms are motivated by self-interest, and that is not necessarily a bad thing. But, too often, we hear commentators suggest that when Greenpeace and Big Business agree on something, it must be a sensible option. Business support for expensive policies such as the Kyoto Protocol – which would have done very little for climate change – indicate otherwise.
- Unfortunately, this convergence of interests can push us to focus on ineffective, expensive responses to climate change. Whenever opposite political forces attract, as activists and big business have in the case of global warming, there is a high risk that the public interest will be caught in the middle.

The Optimism Bias - TIME

Overly positive assumptions can lead to disastrous miscalculations — make us less likely to get health checkups, apply sunscreen or open a savings account, and more likely to bet the farm on a bad investment. But the bias also protects and inspires us: it keeps us moving forward rather than to the nearest high-rise ledge. Without optimism, our ancestors might never have ventured far from their tribes and we might all be cave dwellers, still huddled together and dreaming of light and heat.

Future Optimism Rationality

the key to rising prosperity over the course of human history has been the exchange of goods. This may not seem like a very original point, but Mr. Ridley takes the concept much further than previous writers. He argues that our success as a species, as opposed to earlier hominids, resulted from innate characteristics that allowed us to trade. Not long after Homo sapiens emerged, we were using rare objects, like obsidian blades, far away from the source materials needed to produce them. This suggests that large numbers of commercial links were established even at the hunter-gatherer stage of our development.
"rational optimism." As Mr. Ridley shows, there have been constant predictions of a bleak future throughout human history, but they haven't come true. Our lives have improved dramatically—in terms of lifespan, nutrition, literacy, wealth and other measures—and he believes that the trend will continue. Too often this overwhelming success has been ignored in favor of dire predictions about threats like overpopulation or cancer, and Mr. Ridley deserves credit for confronting this pessimistic outlook.

- Mr. Ridley spends 14 pages saying that everything will be just fine in Africa without our worrying about negative possibilities. This is unfortunate and misguided. Is his optimism justified because things always just happen to work out? Or do good results depend partly on our caring and taking action to prevent and solve problems? These are important questions, and he doesn't answer them.
- As John Stuart Mill said in 1828, in a quote from the book that I especially enjoyed: "I have observed that not the man who hopes when others despair, but the man who despairs when others hope, is admired by a large class of persons as a sage."
- The most obvious instance of excessive pessimism in Mill's era was the "Communist Manifesto." In one of history's great ironies, Karl Marx used the profits from the German textile mills of Friedrich Engels's father to support the writing and distribution of a political philosophy based on pessimism about capitalism.
- Pessimism is often wrong because people assume a world where there is no change or innovation. They simply extrapolate from what is going on today, failing to recognize the new developments and insights that might alter current trends. For too long, for instance, population forecasts have ignored the possibility that population growth would ease as the world became better off, because people who are wealthier and healthier do not feel the need to have so many children. (For more on this issue, see the excellent presentations on the "Gapminder" website of the development expert Hans Rosling.)
- A lot of the rhetoric about sustainability implicitly assumes that we will exhaust our natural resources, as though there will never be any substitution of one commodity for another in the future. But there has always been such substitution. The late economist Julian Simon made a famous wager with the biologist Paul Ehrlich, author of "The Population Bomb." In response to Mr. Ehrlich's prediction that population growth would lead to resource scarcity and mass starvation, Simon bet him that the cost of a basket of commodities, including copper, chromium and nickel, would actually decrease between 1980 and 1990. Mr. Simon won the bet because he believed that, despite increased demand, increased supply would win out. And in fact, to take one example, fiber optics soon took the place of copper wire in many communications technologies.
- Mr. Ridley suggests that all innovation comes from new companies, with no contribution from established companies. As you might expect, I disagree with this view. He also seems to think that innovation involves simply coming up with a new idea, when in fact the execution of the idea is critical
- Mr. Ridley describes the economy of the future as "post-corporatist and post-capitalist," a silly throwaway phrase. He never explains what will replace all the companies that figure out how to make microchips or fertilizer or engines or drugs. Of course, many companies will come and go—that is a key element of capitalism—but corporations will continue to drive most innovation.
- Mr. Ridley underplays the role of other institutions, including education, government, patents and science, all of which, especially since the 19th century, have played a central role in the improvements that humanity has experienced. Too often, when Mr. Ridley finds an example that minimizes the contributions of these institutions, he seems to think that he has validated the idea that exchange deserves all of the credit.
