Scientists Find “64,000 Square Miles of Climate Resilient Ocean” Where “Corals Are More Likely to Survive”

When environmentalists want to highlight the harm from global warming they frequently present the dire plight of the world’s coral reefs as a prime example. Now, in The New York Times Science section, Katharine Houreld reports that a new scientific study documents that the plight is far less dire than environmentalists had previously thought:

(p. D2) As spiking ocean temperatures are devastating reefs around the world, a handful of scientists have found a reason for cautious optimism. They’ve used artificial intelligence to detect sheltered pockets where cool currents, reduced exposure to sunlight and locations outside cyclone paths mean corals are more likely to survive.

The study, led by the Wildlife Conservation Society and presented at the Our Ocean Conference in Mombasa, Kenya, is currently undergoing peer review for publication in the journal Environmental Research Letters.

Five scientists identified 42 factors that create the conditions for the coral havens, called refugia, and then ran those through a program with nearly 38,000 human observations of coral cover and composition gathered over 65 years. The program identified more than 64,000 square miles of climate-resilient ocean in 72 countries.

The work found three times as many refugia as a landmark 2018 assessment known as the 50 Reefs Study, the first paper to systematically identify areas around the globe where coral might still be saved.

An Innovative Entrepreneur Respects Nozickian Moral Side-Constraints

In Openness to Creative Destruction, I distinguish the “innovative entrepreneur” from the “free-agent entrepreneur”: “a ‘free-agent entrepreneur’ is her own boss as she does something that has been done before; an ‘innovative entrepreneur’ is her own boss as she creates a new good or a new process” (Diamond 2019, 2). Here I add a qualification that an entrepreneur is only an innovative entrepreneur if she respects Nozickian moral side-constraints as she creates her new good or process. Libertarian philosopher Robert Nozick defended an individual’s right to seek their own goals, subject to the moral side-constraint (Nozick 1974, 33) that the seeker not make use of “force, theft, fraud” (Nozick 1974, ix). For instance when the executives at Purdue Pharma claimed that OxyContin was nonaddictive, they committed flagrant fraud, violating the Nozickian moral side-constraint, and so while they may have been exemplars of what William Baumol called “destructive entrepreneurship” (Baumol 1990), they have no claim to have been exemplars of “innovative entrepreneurship.”

How Regulations Harm the Worst Off

In my “Innovative Entrepreneurs Replace Despair with Hope” paper (currently undergoing a second round of revision in response to referee requests), I argue that the worst off will benefit if we strengthen a redundant labor market by unbinding innovative entrepreneurs.

Regulations harm the worst off in other ways besides fewer jobs for the worst off. They disproportionately increase consumer prices in the categories, like food, that are most heavily consumed by the worst off (Chambers et al. 2019). They reduce wage growth (Bailey et al. 2019), increase poverty rates (Chambers et al. 2019b), generally increase inequality (Choudhury 2023; Chambers and O’Reilly 2019, 2022), and specifically increase inequality by disproportionately increasing salaries of regulation compliance workers, such as accountants, lawyers, and managers (Bailey et al. 2019, 92-93; Chambers et al. 2019a; Mulholland 2019). Finally, regulations increase mortality (Broughel and Chambers 2022).

Satisfy the Nozick’s Lockean Proviso by Universal Basic Income (UBI) or by Unbinding Entrepreneurship?

The philosopher John Locke gave an account of how it could be just for a person to appropriate land as personal property, when the land previously was open to the common use of everyone. He said that this could be justly done if the appropriator had mixed their labor with the land, say by farming it, so long as there remained an equal amount and quality of land for others to likewise appropriate (Locke [1689] 1963, II sect. 33 p. 333). Many, including Robert Nozick, Matt Zwolinski, and me, find this a plausible account. The problem is how to satisfy what Nozick called “the Lockean proviso” (Nozick 1974, 178-182) that there be an equal amount and quality of land for others to likewise appropriate. Usually the best land will be acquired first, and what remains will be of lower quality. (For example, by the time the German Mennonites came to the U.S. from Russia, the only land left open for them to homestead (mix their labor with) was the prairie of Oklahoma that already was barren and was soon to turn into an unfarmable dust bowl (Egan 2006, 62-72).) So a conscientious political philosopher would seek to preserve the spirit of the Lockean proviso by saying that it could be met if the worst off had some other way, besides mixing their labor with good enough land, that would allow them to support their family and find a path to a better future. Zwolinski (2015) argues that the best other way to satisfy the Lockean proviso is by instituting Universal Basic Income (UBI). I argue that the best other way is for the worst off to have good enough job opportunities, what I call a “redundant labor market,” or else to have good enough free-agent entrepreneurship opportunities.

A Stable Macroeconomy, and the Agglomeration Benefits of Cities, Allow Redundant Labor Markets to Flourish

In my “Innovative Entrepreneurs Replace Despair with Hope” paper (currently undergoing a second round of revision in response to referee requests), I argue that the worst off will benefit if we strengthen a redundant labor market by unbinding innovative entrepreneurs.

Besides unbinding innovative entrepreneurs, two other conditions can strengthen redundant labor markets: a stable macroeconomy and the agglomeration benefits of urban areas.

Many believe that inevitable recessions must periodically undermine the first of these conditions, a stable macroeconomy, and thus threaten an otherwise redundant labor market. But a plausible contrarian view argues that recessions are not inevitable, since they usually are caused by policy mistakes that can be avoided (Furchtgott-Roth 2026; Glynn 2018; Goodspeed 2026; Irwin 2016, 2019a, 2019b; Rudebusch 2016).

For example, Australia achieved 29 years without a recession, allowing a flourishing redundant labor market to attract energetic, smart, young French citizens who could not find jobs in a sclerotic labor market in France (Rubin and Breeden 2015). Australian workers could often move seamlessly between entrepreneurship and jobs (Bradsher 2016). Australian lockdown policies during the Covid-19 pandemic may have contributed to Australia’s first recession in 29 years (Kwai 2020).

In the couple of years before the pandemic, the U.S. economy, though far from a perfect exemplar of a redundant labor market, was strong enough to allow more workers to quit their jobs to seek better jobs (Cutter 2018; Harrison and Morath 2018). The strong economy also allowed more low-skilled workers to find jobs (Ip 2019; Modestino et al. 2016, 2020).

A second condition that contributes to the flourishing of redundant labor markets consists of the agglomeration benefits of urban areas, where firms and workers are both numerous and diverse. The positive effects of this density and diversity are called “agglomeration forces” (Moretti 2013, 124). Unfortunately, these positive forces are weakened by regulations, including zoning and regulations that restrict the construction and development of housing, and thereby limit the extent to which low-skilled workers can move to, and benefit from, redundant labor markets (Herkenhoff et al. 2018; Hsieh and Moretti 2019).

For example, in New York City regulations limit the height of skyscrapers (Glaeser 2011) and require apartments to exceed a minimum size (Bertaud 2018, 11, 47, 231-234, and 258-259). When Alain Bertaud and his wife were young and poor, they were only able to move from Paris to Manhattan because they found a tiny apartment that they could afford. They were delighted because they valued all that Manhattan could offer. But today a Manhattan developer who built such tiny apartments would be violating the law (Bertaud 2019, about an hour into interview).

Some of those who are among the worst off might improve some of their circumstances by moving to one of the few cities (most notably Houston) that have better jobs and do not have zoning laws and other regulations that discourage newcomers (Gray 2022; Siegan 1972). But the increase in hope from a distant job is sometimes countered by the need to commute back to the home community where a spouse, children, or parents have deep roots. When the GM plant closed in Janesville, Wisconsin many of the workers could only find comparable jobs at GM plants hundreds of miles away. Many of them became “GM gypsies” commuting back and forth to Janesville on a weekend, when they could, to see their family (Goldstein 2017, 105). As Amy Goldstein describes them, they persevere less from any hope for a better life, than from a sense of pride, a work ethic.

Innovative New Goods Can Radically Improve Lives

In my Openness book I argue that the kind of economic growth that matters most is not the greater accumulation of old goods like shoes, but the creation of innovative new goods. The story quoted below gives a case-in-point, documenting how driverless cars radically improve the lives of blind passengers.

(p. A20) Mr. Brunt, 28, was born with a rare eye disorder. He can’t drive himself, and had never experienced the feeling of being alone in a car — until Waymo’s self-driving vehicles started navigating San Francisco’s hilly streets two years ago.

Now Mr. Brunt will occasionally make the hourlong journey across the bay from his home in Solano County, Calif., just to ride in one. “It’s that feeling of independence and actually having the control,” he said. “Being able to play whatever music you want, feeling like you’re in your own car.”

. . .

Claire Stanley, who is legally blind and uses a guide dog, said she had also had to “battle” for Uber and Lyft drivers to pick her up at home in Washington, D.C. When she travels to a city with autonomous ride shares, she and her dog, a yellow Labrador named Tulane, jump into them without a struggle.

“When you don’t have a driver, there’s no driver to say no,” she said.

. . .

On a drizzly day last month, Mr. Brunt was heading to the de Young Museum in Golden Gate Park. He had some trouble finding his Waymo’s precise location, so he pressed a button on the app to play a melody from the car and followed the noise.

He hopped into the passenger seat, and his Spotify account immediately connected to the car’s stereo system, blasting his electronic music.

As the steering wheel began to turn, moving the car onto the road, Mr. Brunt, ready to enjoy the ride, leaned his seat back and fiddled with the temperature until it was set to 70 degrees.

“That feeling of independence is amazing,” he said. “It’s something I never thought I would have growing up.”

Entrepreneurial Apple Finds Uses for “Defective” Chips “That Might Otherwise Be Thrown Out”

I am currently revising my “Innovative Entrepreneurs Replace Despair with Hope” paper in which I argue that if we unbind entrepreneurs from regulations they will be free to find new uses for labor that is currently unemployed or underemployed. In the paper I present as proof-of-concept, examples where entrepreneurs found uses for the previously useless, such as the startup that uses milkweed floss as insulation in parkas. I just ran across another example, in the passages quoted below, in which Apple has found uses for defective processor chips that previously would have been thrown out.

(p. A1) Apple, long revered for its premium-priced products, has managed to develop a booming business selling cheaper devices when most gadget makers are being hammered by rising costs.

One of its secrets: using chips with slight defects that might otherwise be thrown out.

The strategy is apparent in the technical minutiae of the newly released $599 MacBook Neo, which early data suggest is a hit with customers.

The chip powering the Neo is Apple’s A18 Pro, the same chip first used inside the iPhone 16 Pro two years ago, but with one key difference. The Neo version of the chip has a “5-core” graphics processor, one less than the version inside the 2024 iPhones, indicating that Apple was able to save some of the A18 Pro chips with a defective core for future use.

Defective cores can be disabled, leaving a chip that still functions perfectly well to power different, often cheaper devices—in this case an entry-level laptop instead of a top-of-the-line iPhone.

. . .

(p. A5) “If you can take the stuff that doesn’t meet highest level specs and still use it, you can save money, scrap and time,” says Tim Culpan, a supply-chain analyst who has written about Apple’s Neo chip orders. “Also you can reach a lot more customers you might not otherwise be able to sell to.”

Apple has used its flexibility with its own silicon to develop lower-priced iPhones and computers, many of which have sold well. The Neo is so popular that Apple is running low on leftover chips and has been forced to order new ones, according to people familiar with its supply chain.

. . .

Using chips in the Neo that might otherwise be tossed is one way Apple was able to deliver its first entry-level laptop.

Entrepreneurial Innovation Celebrated on Good Morning America!

Sunday morning, June 6, I was shocked to be impressed by a replay of a June 3 report on ABC’s Good Morning America, celebrating entrepreneurial perseverance and optimism. It appears that electric planes will receive regulatory approval to start operations in early fall. Maybe Trump’s deregulation push is allowing faster innovation; innovation that is starting to payoff?

Chicago City Council Ends Increases in Restaurant Worker Minimum Wage

The members of the Chicago city council Democrat “machine” might have ended their support for minimum wage increases because they had enrolled en masse in price theory classes at the University of Chicago. But they did not–they likely still are not able to distinguish a supply curve from a demand curve. But apparently a sufficient number of them are able to open their eyes and admit their mistake when their constituents suffer the negative job consequences of an increasing minimum wage.

(p. A15) Chicago’s distressed dining scene—recently described as “on the brink of collapse”—was bolstered by good news last week, as the City Council voted to halt future increases in the minimum wage for servers and bartenders.

. . .

In the first year after the mayor’s minimum wage hike, new restaurant and tavern licenses—a key indicator of industry health—dropped by more than 8%. The Illinois Restaurant Association reported that nearly 500 restaurants closed in the first half of 2025, and 70% of the restaurants that responded to the association’s poll reported cutting staff or reducing employee hours since the wage hike took effect.

. . . Alderwoman Samantha Nugent, who introduced a proposal to stop further increases in the wage, said her constituents were suffering from the mayor’s good intentions: “I’ve had several restaurants close down,” she said. “I’ve heard from servers, when the tip credit changed in Chicago, their hours were cut.”
