Elderly Benefit Most from Air-Conditioning

(p. A18) The aging process makes older bodies generally less capable of withstanding extreme heat, doctors say.

“They’re at extremely high risk of heat stroke and death,” James H. Diaz, a professor of environmental and occupational health sciences at Louisiana State University’s School of Public Health, said of older people. “When we look at what happens with these heat waves, most of the deaths occur in the homebound elderly.”

In many communities, including in New Orleans and Houston, officials have opened cooling centers and shelters in recent weeks, with air-conditioned shuttle buses meandering through neighborhoods, picking people up. Programs are also in place to provide or repair air-conditioners or help people struggling to afford their electricity bills.

. . .

In . . . Orlando, Veronica King, 67, said she keeps her air-conditioner running even if she can’t afford to. “I have to figure out how to cover that bill,” she said, adding that she relies on machines that help her breathe. “When it’s hot, I can’t breathe.”

In Houston, where the heat index could reach 107 degrees on Sunday, Ms. Lowry and her husband, Jasper, 72, have come up with a compromise. They have two cars, neither with working air-conditioning. But they figured they could at least spare the money to repair it in one of them.

“Range Anxiety” Leads Chinese to Prefer Hybrids Over EVs

(p. B12) Don’t write off hybrid electric vehicles.

After Tesla, the most highly valued U.S.-listed EV company isn’t homegrown Rivian or Lucid but Li Auto, a Chinese manufacturer that went public in 2020 by listing American depositary receipts.

. . .

What is surprising is that Li has overtaken NIO to lead the new generation of Chinese startups. Li doesn’t make the purely electric vehicles that were popularized by Tesla and that have become the technological focus of other startups and most old-school car manufacturers. Instead, it specializes in extended-range EVs, which use a generator to power up the battery with gasoline if it runs out of juice.

. . .

The popularity of what is essentially a plug-in hybrid, albeit a cutting-edge one, is notable in the Chinese market, which has in many ways led the transition to EVs.

. . .

But Chinese charging infrastructure is patchy, leading to range anxiety. Brokerage Bernstein expects 65% growth in plug-in hybrid sales in China this year, versus 25% growth for pure EVs.

Is Leonardo’s Ferry Moored Due to Global Warming or Due to Bureaucratic Credentialism?

(p. 4) On a recent sunny morning on the banks of the Adda River in northern Italy, schoolchildren on a class trip to Imbersago — the “Town of the Ferry of Leonardo da Vinci” — gathered next to a moored boat and listened as a guide explained how the flights of the river’s birds, the formations of its rocks and the workings of its ships inspired Leonardo’s genius.

“Why doesn’t it move?” one of the students interrupted, pointing to the ferry, which sat behind a chain and a sign reading, “Service suspended.” It looked like a deserted summer deck atop two rowboats.

. . .

. . . some of the townspeople say an Italian problem more daunting than climate change is the real culprit for the ferry’s immobility since May [2023].

“Bureaucracy,” said John Codara, who owns the gelato shop next to the ferry.

. . .

“I mean Leonardo wasn’t a moron,” he said, under a framed picture of Leonardo. He demonstrated how the ferry worked on a small wooden model made by a local pensioner — “It’s to scale; it’s worth 500 euros,” or nearly $550, and argued that low water and weak currents meant operators required elbow grease to move it across the cable connecting the two banks.

“The force of the ferry is these,” Mr. Codara said, pointing at his biceps.

What they did not need was an advanced nautical degree, he said, as he marched out of his cafe and made a beeline for a sign honoring “The Human Face of the Ferry” and its pilots over the past century. “Harvard, Harvard, Harvard,” Mr. Codara said with derision as he pointed at the names. “They all went to Harvard.”

Roberto Spada, 75, whose father was one of those ferrymen, said he helped navigate the ferry as a 12-year-old and was interested in helping out the town by doing it again as a volunteer.

“I thought with my license I could do it,” Mr. Spada told the mayor as they leaned against other signs posted next to the ferry that featured both Leonardo’s sketch and an excerpt from Dante’s “Inferno” about Charon, “ferryman of the damned.”

A retired truck driver and president of the local fishing association — which has the ferry as its logo — Mr. Spada had a boating license but seemed bewildered as the mayor explained all of the certifications and bureaucratic hoops that needed to be jumped through to pilot the ferry.

“It’s a really long process,” said Mr. Vergani, the mayor.

Argentine Drought Research Shows That Not All Bad Weather Events Are Due to Global Warming

(p. A5) Lack of rainfall that caused severe drought in Argentina and Uruguay last year was not made more likely by climate change, scientists said Thursday [Feb. 16, 2023]. But global warming was a factor in extreme heat experienced in both countries that made the drought worse, they said.

The researchers, part of a loose-knit group called World Weather Attribution that studies recent extreme weather for signs of the influence of climate change, said that the rainfall shortage was a result of natural climate variability.

Specifically, they said, the presence of La Niña, a climate pattern linked to below-normal sea-surface temperatures in the Pacific that influences weather around the world, most likely affected precipitation.

. . .

Friederike Otto, a senior lecturer at Imperial College London who co-founded the group, said that the new research shows “that not every bad thing that is happening now is happening because of climate change.”

“It’s important to show what the realistic impacts of climate change are,” she said.

Did Feds Bail Out Silicon Valley Bank (SVB) Because It Was “a Climate Bank”?

After the article quoted below appeared, the Feds decided to bailout the Silicon Valley Bank. They claimed that this was a selective action–not one they would equally apply to all failed banks.

(p. B1) “Silicon Valley Bank was in many ways a climate bank,” said Kiran Bhatraju, chief executive of Arcadia, the largest community solar manager in the country. “When you have the majority of the market banking through one institution, there’s going to be a lot of collateral damage.”

Community solar projects appear to be especially hard hit. Silicon Valley Bank said that it led or participated in 62 percent of financing deals for community solar projects, which are smaller-scale solar projects that often serve lower-income residential areas.

. . .

The collapse of Silicon Valley Bank threatens to derail what was a fast and growing part of the venture capital sector. More than $28 billion was invested in climate technology start-ups last year, up sharply from the year before, according to HolonIQ, a data provider.

Feds Impose Tariffs on Imports of Paper-Thin Steel Needed to Make EV Engines

(p. A3) Large U.S. steelmakers are ramping up production of a hard-to-make, paper-thin steel to capture a fast-growing market for a material critical to powering electric vehicles.

. . .

Such electrical steel, which accounts for about 1% of all the steel produced annually in the world, already is in short supply for electric vehicles, executives said. Companies expect demand to accelerate faster than production as EV volumes expand in the coming years.

“It’s in limited supply and with very long lead times. Sometimes 50 or 52 weeks,” said Hale Foote, owner of Scandic Springs Inc., a San Leandro, Calif., company that uses high-grade electrical steel to make parts for scientific measurement devices.

. . .

More than 80% of the electrical steel produced comes from China, Japan and South Korea, all countries that are subject to U.S. tariffs or quotas on steel imports, industry analysts said.

. . .

(p. B2) “It takes intense focus. You have to have absolute consistency or you scrap the material,” said David Stickler, who led the investment group that built Big River Steel in Osceola, Ark., and then sold the mill to U.S. Steel in 2021. Mr. Stickler said he envisioned electrical steel being a core product at Big River when he started planning the mill nearly a decade ago.

. . .

Steel-industry executives said that creating more domestic capacity to make electrical steel for vehicles will likely take years, as steel companies acquire equipment and become proficient at the exacting production process.

“You can’t just buy the equipment and start making electrical steel. Those who’ve made the investment will have an advantage for the next five to 10 years,” Mr. Stickler said.

Innovative Farmers Can Adapt to Scarcer Water

(p. D4) The Colorado River, Arizona’s largest water source, is so low that last month, for the first time in history, the federal government proposed cutting water allotments to three states that rely on the river, including Arizona. Climate change is parching soil and depleting aquifers already taxed by corporate agriculture. Large swaths of Arizona farmland are devoted to water-hungry crops like lettuce and hay, grown to feed livestock as far away as Saudi Arabia.

. . .

Drawing on lessons she learned at the Urban Farm, a Phoenix-based business that teaches home gardeners how to grow food in a dry climate, Ms. Norton turned her backyard “from bare-bones, dead-ground scratch” into a lush mix of garden and orchard. She’d be open to raising chickens as well, if not for the presence of predators like coyotes, roadrunners and rattlesnakes.

What appears wild is the result of careful planning. A mulberry tree provides shade for the dragon fruit growing around its trunk. The drip tape that waters apricot, plum and apple trees also irrigates Mexican primrose flowers and sweet potato vines below.

“These grapes are strategically placed to keep the afternoon sun off these young trees,” Ms. Norton said. “I take the leaves and give them to a lady four doors down. She uses them to make dolmas.”

Ms. Norton is an ardent member of the Phoenix area’s sprawling gardening community. She is now general manager of the Urban Farm, and owns a seed business with its founder, Greg Peterson.

. . .

A primary goal of gardeners like Ms. Norton is to naturally rejuvenate soil degraded by synthetic fertilizers and neglect. Zach Brooks started the Arizona Worm Farm to help.

Nearly halfway into a 10-year plan to establish a fully sustainable, off-the-grid farm, Mr. Brooks sees his project as proof of how quickly damaged land can be restored using natural methods. It includes gardens and a food forest, a dense collection of plants that support one another, comprising mostly fruits and vegetables. Together, they provide produce for a small farm store and meals for his 20 employees.

. . .

As challenging as it is to farm and garden around Phoenix, Sterling Johnson said it’s (p. D5) even more so in Ajo, about 100 miles south, which is even hotter and dryer.

“If we can do it out here,” he said, “we think you can do it anywhere.”

“By Far the Biggest Risk to Global Climate Comes From Volcanoes”

(p. C9) What’s the connection between sugar and Xi Jinping? Why does the political turbulence in today’s Middle East trace back to the Cretaceous period? How did the humble potato revolutionize the world? Why did the great Mayan cities of the ninth century run out of potable water? What does the contemporary West African practice of polygyny—one man, many wives—have to do with the trans-Atlantic slave trade?

Peter Frankopan raises these beguiling questions—and many others, bless him—in “The Earth Transformed,” a book that examines the entire sweep of the relationship between humans and nature.

. . .

Whereas Mr. Frankopan never disguises the fact that he is on the greenish side of the climate-change conversation, he steers clear of enviro-preaching and finger-wagging.  . . .  In words that will startle many of us, he says that “by far the biggest risk to global climate comes from volcanoes.” He contrasts the “considerable thought and attention” that have gone into planning for a warming world with the almost complete absence of planning or funding on the likely implications of major volcanic eruptions. Estimates put the chances of a mega-eruption—one that could cost “hundreds of millions of lives”—at one in six before the year 2100.

. . .

The history of the Earth is a history of large-scale transformations that have wreaked havoc in some cases and blessed us with benign climatic eras in others (such as the Roman Warm Period from 300 B.C. to A.D. 500). The most famous instance of the former was the asteroid strike in the Yucatán Peninsula 66 million years ago in which our beloved dinosaurs were wiped out. The rise of humankind, Mr. Frankopan writes, was the result of an “extraordinary series of flukes, coincidences, long shots and serendipities” that made the planet hospitable to our existence. It was “geological chance” that gave the Middle East its oil reserves, the result of warming in Cretaceous times.

. . .

Mr. Frankopan’s thesis is that civilizations thrive best when they are resilient to shocks. Yet “hyperfragility,” he believes, is the name of the game in the 21st century—whether in response to warming, a rudderless U.S., Mr. Xi and Taiwan, Vladimir Putin’s war in Ukraine, or a nuclear Saudi Arabia and Iran. The march of history has left such places as Uruk, Nineveh, Harappa, Angkor and Tikal in ruins, not because of climate change but because of a lack of resilience to shocks, made worse by obtuse planning and even worse decision-making. That’s the lesson Mr. Frankopan is trying to teach us.

Even Environmentalists Face Trade-Offs: Plans to Refill the Salton Sea May Hasten an Overdue Large Earthquake

(p. A1) It has been about three centuries since the last great earthquake on the southern San Andreas Fault, the most treacherous seismic hazard in California. For decades researchers have puzzled over why it has been so long. The average interval of large earthquakes along that portion of the fault has been 180 years over the past 1,000 years.

While seismologists agree that Southern California is due for the Big One, a group of researchers published a paper on Wednesday [June 7, 2023] in the journal Nature that offers a reason for the period of seismic silence along the southern San Andreas, the tension-wracked meeting point of the North American and Pacific tectonic plates.

. . .

Mr. Hill and his co-authors found that major earthquakes along the southern San Andreas fault tended to happen when a large body of water, Lake Cahuilla, was filling or was full with water from the Colorado River in what are now the Coachella and Imperial valleys.

The lake has drained over the last three centuries and all that remains is the vestigial Salton Sea.

. . .

The research published in Nature, which builds on a paper on which Dr. Philibosian was a writer in 2011, raises questions about plans to rehabilitate parts of the Salton Sea, . . . .  . . .  As the sea dries out, toxic dust is left behind and blown into the air, posing a hazard for nearby residents.

. . .

Impounding more water in the Salton Sea could tamp down the dust.Impounding more water in the Salton Sea could tamp down the dust.  . . .  But a major change in the water level could also trigger seismic activity, according to Dr. Philibosian.

Environmentalists Now Worry We Will Run Low on Squirrels

Really? Our dachshund, Walter Disney Diamond, would be happy to ship a few squirrels to whoever is worried. (His main activity is to dash outside to angrily defend our property rights in our fence against constantly interloping squirrels.)

(p. A19) Male Arctic ground squirrels go through puberty every year. As if that wasn’t hard enough, now the females have a problem, too.

According to a paper published on Thursday [May 25, 2023] in the journal Science, climate change appears to be making them emerge from hibernation earlier. That matters, because it could throw off the timing of the animals’ mating cycle.

. . .

Any decline in squirrel populations could disrupt the local food web. Almost all Arctic predators, from wolves to eagles, rely on them as a food source.

Opponents of Geoengineering View Global Warming as Nature’s Just Punishment of Us for Our Indulging in Technology and Capitalism

(p. A13) Make no mistake—Mr. Myhrvold is concerned about climate change.  . . .

He laments that policy makers largely scorn geoengineering—human interventions in the Earth’s natural systems to thwart or neutralize climate change.

. . .

Geoengineering is about “deliberately trying to reduce climate change.” Excess CO2 traps a little less than 1% of heat from the sun, “so if we could make the sun 1% dimmer, we could shut off climate change.” When Mount Pinatubo, a volcano in the Philippines, erupted in 1991, it lowered world-wide temperatures by 1 degree Celsius for about 18 months. Human-emitted particulate pollution has historically offset about 20% of human-emitted CO2. “Ironically,” he says, “the Clean Air Act made our air better but hurt climate change.”

The simplest solar-radiation management scheme, Mr. Myhrvold says, “is to emit particles in the stratosphere to mimic Mount Pinatubo. We invented a particularly elegant way to do this with balloons and a pipe to the sky.” By “we,” he means Intellectual Ventures, the company Mr. Myhrvold founded in 2000 after leaving Microsoft, where he spent 13 years and rose to the position of chief technology officer. Intellectual Ventures “creates, incubates and commercializes” new inventions.

“Marine cloud brightening” is another solar-related intervention. “The idea is to increase the number and size of low clouds that form over the oceans so that more incoming sunlight bounces back into space instead of heating the ocean.” Scientists have proposed a variety of ways to do this. One, which Mr. Myhrvold’s company has explored, is to outfit ships with equipment to spray seawater into the air as they traverse the ocean. “The salt particles can serve as nuclei for water vapor to condense into droplets, thus forming clouds.”

. . .

“Opponents worry that once you have geoengineering, people won’t make sacrifices to cut emissions. They want a sword of Damocles hanging over humanity as a means to force us to follow their ideology.”

Mr. Myhrvold uses an analogy he describes as “horrible in some ways.” When the AIDS epidemic hit, some people saw it as punishment from God. “Their attitude was, ‘This is what you get if you indulge in the practices we don’t approve of.’ ” In climate change, he says, this moralistic attitude takes the following form: “I don’t like aspects of our society, I don’t like technology, I don’t like capitalism, and this is nature’s retribution. And so we have to change the way we live.” Such beliefs “have become a very powerful disincentive, particularly for academic researchers.”

. . .
