Above is a scan of a napkin I picked up at a tasty little pizza restaurant we stopped at in Brisbane, Australia this July.
Every time I see the napkin, I smile.

Preindustrial Icelanders Adapted to Adverse Global Cooling
(p. 254) We investigate the effect of climate on population levels in preindustrial Iceland. We find that short-term temperature changes affect the population growth rate. In particular, a 1ºC decrease in temperature causes about 0.57 percent decrease in the population growth rate for the two subsequent years, for a total effect of 1.14 percent. This effect appears to attenuate as the growth rate returns to trend in subsequent years. We also quantify the extent to which eighteenth- and nineteenth-century Icelanders adapt to long-run climate change. In particular, the data suggest that long-run adaptation to climate takes about 20 years and reduces the effect of cold shocks by about 60 percent. Our results also allow us to approximate the effect of permanent climate change on steady-state population levels. This approximation suggests that steady state population levels decrease by 10 percent to 26 percent for each 1ºC of sustained adverse temperature change.
(p. 255) . . .
If contemporary poor agricultural populations behave like their eighteenth- and nineteenth century Icelandic counterparts, then our results suggest that adverse climate change (which now refers to warming, not cooling) will have three effects. First, in the short run it will lead to a significant decrease in population growth rates. Second, over the course of a generation, adaptation will offset about 60 percent of the short run effects. Finally, in the long run, we expect a decrease in steady-state populations.

Government Disaster Relief Crowds Out Private Self-Protection
(p. 242) This paper has investigated the role of natural disaster shocks in determining gross migration flows, controlling for other place-based features. Using two micro datasets, we documented that in the 1920s and 1930s population was repelled from tornado-prone areas, with a larger effect on potential in-migrants than on existing residents, while flood events were associated with net inmigration. The differential migration responses by disaster type raises the question of whether public efforts at disaster mitigation counteract individual migration decisions. The nascent investment in rebuilding and protecting flood-prone areas could provide one example of public investment crowding out private self-protection (i.e., migration).
(p. 243) In future work, we plan to explore the role of New Deal disaster management more directly by exploiting variation across SEAs in federal expenditures and representation on key congressional committees. We predict that residents of areas that received federal largesse after a disaster in the 1930s will be less likely to move out and that new arrivals may be more likely to move in, while residents of areas that benefited less from New Deal spending will continue to use migration as a means of self-protection.

(p. D3) A freshwater snail has been rediscovered on the Cahaba River in Alabama, 12 years after it was declared extinct.
Nathan Whelan, a graduate student in biology at the University of Alabama, spotted the snail — called the oblong rocksnail, or Leptoxis compacta — on a small stretch of the river.

Ice Melts too Slowly for Obama Backed Arctic Oil Project
Source of map: online version of the WSJ article quoted and cited below.
(p. B1) Royal Dutch Shell . . . is spending billions of dollars to drill the first oil wells in U.S. Arctic waters in 20 years, backed by an Obama administration eager to show it wasn’t opposed to offshore exploration.
But the closely watched project isn’t going the way the company or the government hoped–illustrating the continuing challenge of plumbing for natural riches in one of the world’s most unforgiving locations.
Sea ice in the Chukchi and Beaufort seas off the northern Alaska coast was slow to break up this year, leaving the drilling areas inaccessible much later than anticipated.

Economists Optimistic that Economy Can Adapt to Climate Change
Source of book image: http://www.bibliovault.org/thumbs/978-0-226-47988-0-frontcover.jpg
(p. 222) Efficient policy decisions regarding climate change require credible estimates of the future costs of possible (in)action. The edited volume by Gary Libecap and Richard Steckel contributes to this important policy discussion by presenting work estimating the ability of economic actors to adapt to a changing climate. The eleven contributed research chapters primarily focus on the historical experience of the United States and largely on the agricultural sector. While the conclusions are not unanimous, on average, the authors tend to present an optimistic perspective on the ability of the economy to adapt to climate change.

Environmental “Witch-Hunt” Kills “Golden Rice”
(p. C4) Vitamin A deficiency affects the immune system, leading to illness and frequently to blindness. It probably causes more deaths than malaria, HIV or tuberculosis, killing as many people every single day as the Fukushima tsunami. It can be solved by eating green vegetables and meat, but for many poor Asians, who can afford only rice, that remains an impossible dream. To deal with the problem, “biofortification” with genetically modified food plants is 1/10th as costly as dietary supplements.
“Golden rice”–with two extra genes to make beta-carotene, the raw material for vitamin A–was a technical triumph, identical to ordinary rice except in color. Painstaking negotiations led to companies waiving their patent rights so the plant could be grown and regrown free by anybody.
Yet today, 14 years later, it still has not been licensed to growers anywhere in the world. The reason is regulatory red tape deliberately imposed to appease the opponents of genetic modification, which Adrian Dubock, head of the golden rice project, describes as “a witch-hunt for suspected theoretical environmental problems…[because] many activist NGOs thought that genetically engineered crops should be opposed as part of their anti-globalization agenda.”
It is surprising to find that an effective solution to the problem consistently rated by experts as the poor world’s highest priority has been stubbornly opposed by so many pressure groups supposedly acting on behalf of the poor.

Global Warming Heretic Svensmark May Be the Next Shechtman
(p. C) The list of scientific heretics who were persecuted for their radical ideas but eventually proved right keeps getting longer. Last month, Daniel Shechtman won the Nobel Prize for the discovery of quasicrystals, having spent much of his career being told he was wrong.
“I was thrown out of my research group. They said I brought shame on them with what I was saying,” he recalled, adding that the doyen of chemistry, the late Linus Pauling, had denounced the theory with the words: “There is no such thing as quasicrystals, only quasi-scientists.”
The Australian medical scientist Barry Marshall, who hypothesized that a bacterial infection causes stomach ulcers, received similar treatment and was taken seriously only when he deliberately infected himself, then cured himself with antibiotics in 1984. Eventually, he too won the Nobel Prize.
. . .
Perhaps it’s at least worth guessing which of today’s heretics will eventually win a Nobel Prize. How about the Dane Henrik Svensmark? In 1997, he suggested that the sun’s magnetic field affects the earth’s climate–by shielding the atmosphere against cosmic rays, which would otherwise create or thicken clouds and thereby cool the surface. So, he reasoned, a large part of the natural fluctuations in the climate over recent millennia might reflect variation in solar activity.
Dr. Svensmark is treated as a heretic mainly because his theory is thought to hinder the effort to convince people that recent climatic variation is largely manmade, not natural, so there is a bias toward resisting his idea. That does not make it right, but some promising recent experiments at CERN (the European Organization for Nuclear Research) raise the probability that Dr. Svensmark might yet prove to be a Shechtman.

Shedding Light, or “The Greatest Symbol of Modern Progress”
Source of book image: http://www.vtmagazine.vt.edu/fall06/news.html
(p. 5) IN the wake of widespread violence during the New York City blackout of 1977, a newspaper columnist quipped that just one flick of a light switch separated civilization from primordial chaos.
Leaving the hyperbole aside, artificial illumination has arguably been the greatest symbol of modern progress. By making nighttime infinitely more inviting, street lighting — gas lamps beginning in the early 1800s followed by electric lights toward the end of the century — drastically expanded the boundaries of everyday life to include hours once shrouded in darkness. Today, any number of metropolitan areas in the United States and abroad, bathed in the glare of neon and mercury vapor, bill themselves as 24-hour cities, open both for business and pleasure.
. . .
. . . there was never any question that 19th-century communities welcomed lamps, which in conjunction with police forces, posed a powerful deterrent to lawlessness. Another benefit lay in the numerous pedestrians drawn by their inviting glow, whose very presence helped to discourage crime.
“As safe and agreeable to walk out in the evening as by day-light,” pronounced a New Yorker in 1853.
Certainly, public anxiety over the recent removal of lamps should not be minimized. No longer are there witches and wolves to fear, but research strongly suggests, as one might expect, the critical value of street lighting as a hindrance to crime and serious accidents.
. . .
Financial costs and public safety, however, are not the only issues. Without the benefit of street lighting, towns and cities, after sunset, will be diminished as communities. Families will be more apt to “cocoon” at home, rather than visit friends or attend sporting and cultural events. And, too, our appreciation for night itself will suffer. Evenings can be best enjoyed if they remain inviting and safe, whether for neighborhood gatherings, walking Fido or gazing at the heavens — all with less chance of losing your wallet or stumbling into a ditch.

Love Canal as a “Pseudo-Event” Caused by an “Availability Cascade”
(p. 142) An availability cascade is a self-sustaining chain of events, which may start from media reports of a relatively minor event and lead up to public panic and large-scale government action. On some occasions, a media story about a risk catches the attention of a segment of the public, which becomes aroused and worried. This emotional reaction becomes a story in itself, prompting additional coverage in the media, which in turn produces greater concern and involvement. The cycle is sometimes sped along deliberately by “availability entrepreneurs,” individuals or organizations who work to ensure a continuous flow of worrying news. The danger is increasingly exaggerated as the media compete for attention-grabbing headlines. Scientists and others who try to dampen the increasing fear and revulsion attract little attention, most of it hostile: anyone who claims that the danger is overstated is suspected of association with a “heinous cover-up.” The issue becomes politically important because it is on everyone’s mind, and the response of the political system is guided by the intensity of public sentiment. The availability cascade has now reset priorities. Other risks, and other ways that resources could he applied for the public good, all have faded into the background.
Kuran and Sunstein focused on two examples that are still controversial: the Love Canal affair and the so-called Alar scare. In Love Canal, buried toxic waste was exposed during a rainy season in 1979, causing contamination of the water well beyond standard limits, as well as a foul smell. The residents of the community were angry and frightened, and one of them, (p. 143) Lois Gibbs, was particularly active in an attempt to sustain interest in the problem. The availability cascade unfolded according to the standard script. At its peak there were daily stories about Love Canal, scientists attempting to claim that the dangers were overstated were ignored or shouted down, ABC News aired a program titled The Killing Ground, and empty baby-size coffins were paraded in front of the legislature. A large number of residents were relocated at government expense, and the control of toxic waste became the major environmental issue of the 1980s. The legislation that mandated the cleanup of toxic sites, called CERCLA, established a Superfund and is considered a significant achievement of environmental legislation. It was also expensive, and some have claimed that the same amount of money could have saved many more lives if it had been directed to other priorities. Opinions about what actually happened at Love Canal are still sharply divided, and claims of actual damage to health appear not to have been substantiated. Kuran and Sunstein wrote up the Love Canal story almost as a pseudo-event, while on the other side of the debate, environmentalists still speak of the “Love Canal disaster.”

Bicyclists Create Negative Externalities for Pedestrians
“Bicyclists weave through pedestrians and motor traffic on Friday in San Francisco, where a fatal bike-pedestrian collision has sparked debate.” Source of caption and photo: online version of the WSJ article quoted and cited below.
(p. A3) SAN FRANCISCO–City prosecutors said they would file felony vehicular-manslaughter charges against a bicyclist who allegedly hit and killed a pedestrian, in a case that has become a flash point for debate over bicyclists’ rights in the city.
The manslaughter charges–unusually stiff for a bicycle accident–stem from a March 29 incident, when 36-year-old bicyclist Chris Bucchere allegedly ran a red traffic light and plowed into 71-year-old Sutchi Hui in a crosswalk. Mr. Hui died April 2 of injuries related to the collision.
. . .
The bicycle backlash has come to a head after a series of pedestrian deaths in the San Francisco Bay area. A 67-year-old woman died last August after a bicyclist allegedly hit her in a crosswalk after running a red light; the cyclist was convicted of a misdemeanor. Earlier this month, a cyclist allegedly struck and killed a 92-year-old woman in the suburb of El Cerrito while crossing a street; that case is under investigation.
