Hygiene Hypothesis Says Parasites Help the Immune System to Develop

(p. D6) The kakapo, a large flightless parrot that can live 95 years and perhaps longer, is dangerously close to extinction. Once found throughout New Zealand, the population has dwindled to fewer than 150.

Conservation biologists are doing everything they can to keep the kakapo from vanishing. And so, when they discovered a few years ago that a pair of captive kakapos were infected with tapeworms, they did the obvious thing: They dewormed the birds.

Hamish G. Spencer, a geneticist at the University of Otago in New Zealand, thinks that was unwise. If endangered species are going to escape extinction, he argues, they may need parasites to survive.

“Some of these parasites may turn out to be quite good for their hosts,” Dr. Spencer said.

. . .

Evidence accumulated over the decades for what came to be known as the hygiene hypothesis. Supporters argued that over the past two centuries, modern civilization has radically changed our relationship with our inner residents.

For millions of years, our evolving bodies had to strike a tricky balance. We depended on a powerful immune system to fend off deadly infections. But if the immune system were to attack indiscriminately, it could destroy the body’s beneficial bacteria, for example, or damage its tissues with relentless inflammation.

According to the hygiene hypothesis, our ancestors came to tolerate low levels of infection. They even came to depend on parasites to help the immune system develop properly.

. . .

It’s possible, Dr. Spencer said, that the lack of parasites may help explain why some species restoration projects have been disappointing. “There are a number of cases where reintroduced populations haven’t done very well,” he said. “It might be that their immune systems are not very good.”

. . .

A first step, Dr. Spencer said, would be to stop medicating captive animals so freely. “We are arguing against the idea that you just dose the hell out of everything before you put animals back in the wild,” he said.

Musk Will Downsize Government and “Remove Absurd Regulations”

(p. B4) If Elon Musk becomes chief red-tape cutter in a second Trump administration, he is already giving a taste of what’s to come.

. . .

. . ., he often talks about how regulations can be like little strings that collectively tie down a giant like Gulliver, and strip us of our freedoms.

. . .

A Trump victory could give the country, according to Musk, a rare opportunity to clean house unseen since the Reagan administration’s massive deregulation effort.

“It’s been a long time since there was a serious effort to reduce the size of government and to remove absurd regulations,” Musk said during an appearance this month at the “All-In Podcast” conference.

While he skirted what exactly he would do, Musk made it clear that the EPA was the kind of agency on his mind. He pointed to a proposed fine of about $148,000 by the EPA announced this month over claims of SpaceX improperly discharging deluge water and spilling liquid oxygen at its South Texas launchpad.

Musk called it an example of “irrational regulation” and compared the company’s actions to dumping drinking water on the ground. “There was no actual harm done,” he said. “It was just water to cool the launchpad during lift off.”

. . .

Neuralink announced a regulatory win this past week. Musk’s brain-implant company said the Food and Drug Administration had awarded its experimental Blindsight microchip, which aims to restore sight, a special designation intended for medical devices aimed at treating life-threatening or irreversible debilitating conditions.

If successful, it sounds like the stuff out of TV’s “Star Trek: The Next Generation.”

“Provided the visual cortex is intact, it will even enable those who have been blind from birth to see for the first time,” Musk said this past week.

It is those kinds of advancements that excite his fans and why it can be so hard to rein him in amid public support.

Volcanoes Release Enough Carbon Dioxide to Raise the Temperature by 60 Degrees

So an Oxford geologist finds that “volcanoes release vast amounts of carbon dioxide” and that release is mostly a good thing since without it the Earth “would chill by nearly 60 degrees.” Environmentalists are stressing that the temperature of the Earth may go up by a few degrees. Imagine how the environmentalists would stress if the volcanoes stopped releasing carbon dioxide and the temperature started going down by 60 degrees. That would indeed be something to stress about.

(p. 8) Tamsin Mather, a geologist at the University of Oxford, has no such difficulty. She has spent her career visiting volcanoes to understand how they work, and she has come to see Earth not as a peaceful world encased in a stable crust, but a globe of barely contained geological storms.

“Adventures in Volcanoland” is organized around trips Mather has taken throughout her career, starting with Vesuvius, which she first visited as a child on a family vacation. Next comes the Nicaraguan volcano Masaya, which she studied as a graduate student, and then volcanoes on other continents.

. . .

In her own research, Mather has specialized in measuring the gases that volcanoes emit. Even when they’re not erupting, volcanoes release vast amounts of carbon dioxide. Without that heat-trapping gas, an icehouse effect would replace the greenhouse effect, and the planet’s temperature would chill by nearly 60 degrees.

For the most part, Earth is able to keep its climate stable. While volcanoes warm the planet, chemical reactions draw off carbon dioxide from the air, ultimately delivering it deep underground.

This planetary thermostat is not enough to keep volcanoes from periodically unleashing hell, though. Vast eruptions may be responsible for most of the mass extinctions in life’s history.

Before Co-founding “Colossal” Private For-Profit Firm, George Church “Was Planning on Slogging Along at a Slow Pace” in Academia

Harvard Professor George Church chooses to pursue his bold dream of bringing wooly mammoths back to life through a private firm rather than through a nonprofit organization or an educational institution. Is that because nimble innovation is less constrained in a private for-profit firm?

(p. D3) A team of scientists and entrepreneurs announced on Monday that they have started a new company to genetically resurrect the woolly mammoth.

The company, named Colossal, aims to place thousands of these magnificent beasts back on the Siberian tundra, thousands of years after they went extinct.

“This is a major milestone for us,” said George Church, a biologist at Harvard Medical School, who for eight years has been leading a small team of moonlighting researchers developing the tools for reviving mammoths. “It’s going to make all the difference in the world.”

. . .

The idea behind Colossal first emerged into public view in 2013, when Dr. Church sketched it out in a talk at the National Geographic Society.

. . .

Russian ecologists have imported bison and other living species to a preserve in Siberia they’ve dubbed Pleistocene Park, in the hopes of turning the tundra back to grassland. Dr. Church argued that resurrected woolly mammoths would be able to do this more efficiently. The restored grassland would keep the soil from melting and eroding, he argued, and might even lock away heat-trapping carbon dioxide.

Dr. Church’s proposal attracted a lot of attention from the press but little funding beyond $100,000 from PayPal co-founder Peter Thiel.

. . .

“Frankly, I was planning on slogging along at a slow pace,” Dr. Church said. But in 2019, he was contacted by Ben Lamm, the founder of the Texas-based artificial intelligence company Hypergiant, who was intrigued by press reports of the de-extinction idea.

Mr. Lamm visited Dr. Church’s lab, and the two hit it off. “After about a day of being in the lab and spending a lot of time with George, we were pretty passionate on pursuing this,” Mr. Lamm said.

Mr. Lamm began setting up Colossal to support Dr. Church’s work, all the way from tinkering with DNA to eventually placing “a functional mammoth,” as Dr. Hysolli calls it, in the wild.

The company’s initial funding comes from investors ranging from Climate Capital Collective, an investment group that backs efforts to lower carbon emissions, to the Winklevoss twins, known for their battles over Facebook and investments in Bitcoin.

. . .

Heather Browning, a philosopher at the London School of Economics, said that whatever benefits mammoths might have to the tundra will need to be weighed against the possible suffering that they might experience in being brought into existence by scientists.

“You don’t have a mother for a species that — if they are anything like elephants — has extraordinarily strong mother-infant bonds that last for a very long time,” she said. “Once there is a little mammoth or two on the ground, who is making sure that they’re being looked after?”

And Colossal’s investors may have questions of their own: How will these mammoths make any money? Mr. Lamm predicted that the company would be able to spin off new forms of genetic engineering and reproductive technology.

“We are hopeful and confident that there will be technologies that come out of it that we can build individual business units out of,” Mr. Lamm said.

Cloud Brightening Could Counter Global Warming

If the costs of global warming become large enough, we can brighten clouds to reverse global warming.

(p. A1) A little before 9 a.m. on Tuesday [April 2, 2024], an engineer named Matthew Gallelli crouched on the deck of a decommissioned aircraft carrier in San Francisco Bay, pulled on a pair of ear protectors, and flipped a switch.

A few seconds later, a device resembling a snow maker began to rumble, then produced a great and deafening hiss. A fine mist of tiny aerosol particles shot from its mouth, traveling hundreds of feet through the air.

It was the first outdoor test in the United States of technology designed to brighten clouds and bounce some of the sun’s rays back into space, a way of temporarily cooling a planet that is now dangerously overheating. The scientists wanted to see whether the machine that took years to create could consistently spray the right size salt aerosols through the open air, outside of a lab.

If it works, the next stage would be to aim at the heavens and try to change the composition of clouds above the Earth’s oceans.

. . .

(p. A14) Brightening clouds is one of several ideas to push solar energy back into space — sometimes called solar radiation modification, solar geoengineering, or climate intervention. Compared with other options, such as injecting aerosols into the stratosphere, marine cloud brightening would be localized and use relatively benign sea salt aerosols as opposed to other chemicals.

. . .

“I hope, and I think all my colleagues hope, that we never use these things, that we never have to,” said Sarah Doherty, an atmospheric scientist at the University of Washington and the manager of its marine cloud brightening program.

. . .

But it’s vital to find out whether and how such technologies could work, Dr. Doherty said, in case society needs them. And no one can say when the world might reach that point.

In 1990, a British physicist named John Latham published a letter in the journal Nature, under the heading “Control of Global Warming?,” in which he introduced the idea that injecting tiny particles into clouds could offset rising temperatures.

Dr. Latham later attributed his idea to a hike with his son in Wales, where they paused to look at clouds over the Irish Sea.

“He asked why clouds were shiny at the top but dark at the bottom,” Dr. Latham told the BBC in 2007. “I explained how they were mirrors for incoming sunlight.”

Dr. Latham had a proposal that may have seemed bizarre: create a fleet of 1,000 unmanned, sail-powered vessels to traverse the world’s oceans and continuously spray tiny droplets of seawater into the air to deflect solar heat away from Earth.

The idea is built on a scientific concept (p. A15) called the Twomey effect: Large numbers of small droplets reflect more sunlight than small numbers of large droplets. Injecting vast quantities of minuscule aerosols, in turn forming many small droplets, could change the composition of clouds.

“If we can increase the reflectivity by about 3 percent, the cooling will balance the global warming caused by increased C02 in the atmosphere,” Dr. Latham, who died in 2021, told the BBC. “Our scheme offers the possibility that we could buy time.”

A version of marine cloud brightening already happens every day, according to Dr. Doherty.

As ships travel the seas, particles from their exhaust can brighten clouds, creating “ship tracks,” behind them. In fact, until recently, the cloud brightening associated with ship tracks offset about 5 percent of climate warming from greenhouse gases, Dr. Doherty said.

Ironically, as better technology and environmental regulations have reduced the pollution emitted by ships, that inadvertent cloud brightening is fading, as well as the cooling that goes along with it.

A deliberate program of marine cloud brightening could be done with sea salts, rather than pollution, Dr. Doherty said.

The Benefits of the “Energy Transition” Are Distant and Uncertain, While the Costs Are Immediate and Large

(p. A15) The 2015 Paris Agreement aspired to “reduce the risks and impacts of climate change” by eliminating greenhouse-gas emissions in the latter half of this century. The centerpiece of the strategy was a global transition to low-emission energy systems.

. . .

The energy transition’s purported climate benefits are distant, vague and uncertain while the costs and disruption of rapid decarbonization are immediate and substantial. The world has many more urgent needs, including the provision of reliable and affordable energy to all.  . . .

U.S. and European governments are trying to induce an energy transition by building or expanding organizations and programs favoring particular “clean” technologies, including wind and solar generation, carbon capture, hydrogen production and vehicle electrification. Promoting technological innovation is a worthy endeavor, but such efforts face serious challenges as costs and disruptions grow without tangible progress in reducing local, let alone global, emissions. Retreats from aggressive goals are already under way in Europe, with clear signs of mandate fatigue. The climbdown will be slower in the U.S., where subsidies create constituencies that make it more difficult to reverse course.

. . . today’s ineffective, inefficient, and ill-considered climate-mitigation strategies will be abandoned, making room for a more thoughtful and informed approach to responsibly providing for the world’s energy needs.

The New York Times Is Open to the Possibility and Desirability of Geoengineering

In the past, The New York Times either ignored, or was dismissive of, geoengineering to reverse or mitigate the alleged future effects of global warming. A few months ago, I was pleasantly surprised to see the paper publish a page one article, quoted below, that was open to the policy of geoengineering. This is progress because the left’s standard response to the alleged effects of global warming is to advocate reduced economic growth. Geoengineering would allow economic growth, and the human flourishing it allows, to continue, even if global warming becomes as severe as the pessimists fear.

(p. 1) On a windswept Icelandic plateau, an international team of engineers and executives is powering up an innovative machine designed to alter the very composition of Earth’s atmosphere.

If all goes as planned, the enormous vacuum will soon be sucking up vast quantities of air, stripping out carbon dioxide and then locking away those greenhouse gases deep underground in ancient stone — greenhouse gases that would otherwise continue heating up the globe.

Just a few years ago, technologies like these, that attempt to re-engineer the natural environment, were on the scientific fringe. They were too expensive, too impractical, too sci-fi. But with the dangers from climate change worsening, and the world failing to meet its goals of slashing greenhouse gas emissions, they are quickly moving to the mainstream among both scientists and investors, despite questions about their effectiveness and safety.

. . .  Once science fiction, today these ideas are becoming reality.

Researchers are studying ways to block some of the sun’s radiation. They are testing whether adding iron to the ocean could carry carbon dioxide to the sea floor. They are hatching plans to build giant parasols in space. And with massive facilities like the one in Iceland, they are seeking to reduce the concentration of carbon dioxide in the air.

. . .

(p. 12) A plant similar to the one in Iceland, but far larger, is being built in Texas by Occidental Petroleum, the giant oil company.

. . .

The Occidental plant, being built near Odessa, Texas, and known as Stratos, will be more than 10 times more powerful than Mammoth, powered by solar energy, and have the potential to capture and sequester 500,000 metric tons of carbon dioxide per year.

It uses a different process to extract carbon dioxide from the air, though the goal is the same: Most of it will be locked away deep underground. But at least some of the carbon dioxide, Occidental says, will also be used to extract more oil.

In that process, carbon dioxide is pumped into the ground to force out oil that might otherwise be too difficult to reach. Techniques like this have made Occidental a company worth more than $50 billion and helped send American crude production to a new high in recent years.

Of course, it is the world’s reliance on the burning of oil and other fossil fuels that has so dangerously sent carbon dioxide levels soaring. In the atmosphere, carbon dioxide acts as a blanket, trapping the sun’s heat and warming the world.

Today, Occidental says it is trying to become a “carbon management” company as well as an oil producer. Last year, it paid $1.1 billion for a start-up called Carbon Engineering that had developed a way to soak up carbon dioxide from the air, and began building the Stratos project. Today, what was a barren plot of dirt less than 12 months ago is a bustling construction site.

“It’s like the Apollo missions at NASA,” said Richard Jackson, who oversees carbon management and domestic oil operations at Occidental. “We’re trying to move as quickly as we can.”

“People Will Die” from Blackouts Caused by Walz’s Net-Zero Climate Policies

(p. A13) Minnesota Gov. Tim Walz last year signed one of America’s most aggressive climate laws, mandating that 100% of the state’s electricity come from carbon-free sources by 2040. Even if he doesn’t ascend to national office, he may end up leaving not only Minnesota but other states in the dark. As we show in a new paper, politicians like Mr. Walz are destroying the electricity markets that are essential to economic success and even individual survival.

We analyzed seven Great Lakes states with connected electricity grids—Illinois, Indiana, Minnesota, Michigan, Ohio, Pennsylvania and Wisconsin. For decades, these states have bought and sold electricity in regional markets, benefiting from the abundance of reliable power generated from sources like coal, natural gas and nuclear. But through a combination of state mandates and utility company decisions, all of them are moving away from those reliable sources toward unreliable wind and solar power, in pursuit of net-zero greenhouse gas emissions.

. . .

When subzero temperatures sweep across the Great Lakes every January, states will increasingly ask each other for power that doesn’t exist. Ditto when heat waves crest in July and August. Factories will lose power—a death knell for competitiveness—while families will lose air conditioning or heat. In Michigan, we estimate that a wind-, solar- and battery-based grid will cause blackouts lasting as long as three days during extreme winter weather. People will die.

Pious Climate “Scare Tactics” Lead to Despondency and Bad Policy

(p. A15) Whatever happened to polar bears? They used to be all climate campaigners could talk about, but now they’re essentially absent from headlines. Over the past 20 years, climate activists have elevated various stories of climate catastrophe, then quietly dropped them without apology when the opposing evidence becomes overwhelming. The only constant is the scare tactics.

. . .

After years of misrepresentation, it finally became impossible to ignore the mountain of evidence showing that the global polar-bear population has increased substantially.

. . .

For the past three years the Great Barrier Reef has had more coral cover than at any point since records began in 1986, with 2024 setting a new record.

. . .

Today, killer heat waves are the new climate horror story. In July President Biden claimed “extreme heat is the No. 1 weather-related killer in the United States.”

He is wrong by a factor of 25. While extreme heat kills nearly 6,000 Americans each year, cold kills 152,000, of which 12,000 die from extreme cold. Even including deaths from moderate heat, the toll comes to less than 10,000. Despite rising temperatures, age-standardized extreme-heat deaths have actually declined in the U.S. by almost 10% a decade and globally by even more, largely because the world is growing more prosperous. That allows more people to afford air-conditioners and other technology that protects them from the heat.

. . .

Scare tactics leave everyone—especially young people—distressed and despondent. Fear leads to poor policy choices that further frustrate the public. And the ever-changing narrative of disasters erodes public trust.

Telling half-truths while piously pretending to “follow the science” benefits activists with their fundraising, generates clicks for media outlets, and helps climate-concerned politicians rally their bases. But it leaves all of us poorly informed and worse off.

“Heavily Subsidized Renewables” Mostly Add to Total Energy Consumed Instead of Replacing Fossil Fuels

(p. A17) Despite extravagant hype, the green-energy transition from fossil fuels isn’t happening. Achieving a meaningful shift with current policies is too costly. We need to change policy direction entirely.

. . .

Studies show that when countries add more renewable energy, it does little to replace coal, gas or oil. It simply adds to energy consumption. Recent research shows that for every six units of green energy, less than one unit displaces fossil-fuel energy. The Biden administration finds that while renewable energy sources worldwide will dramatically increase up to 2050, that won’t be enough even to begin replacing fossil fuels—oil, gas and coal will all keep increasing, too.

. . .

The current plan underpinning the green-energy transition mostly insists that pushing heavily subsidized renewables will magically make fossil fuels disappear. But such expectations are “misleading,” as a 2019 academic study concluded. During past additions of a new energy source, the researchers found, it has been “entirely unprecedented for these additions to cause a sustained decline in the use of established energy sources.”

What causes us to change our relative use of energy? One study investigated 14 shifts that happened over the past five centuries, such as when farmers went from plowing fields with animals to tractors powered by fossil fuels. Invariably, the new energy source would be better or cheaper.

. . .

The way to achieve an eventual transition is to improve green-energy alternatives. That means investing much more in research and development. Innovation is needed in wind and solar, as well as storage, nuclear energy, and other possible solutions. Bringing the costs of low-CO2₂energy sources below those of fossil fuels is the only way that green solutions can be implemented globally, and not merely by a few wealthy countries.

When politicians say the green transition is here, they are really asking voters to support throwing more good money after bad. We need to be smarter.

Climate-Change-Induced Flooding Blamed for Hurting Tiny Flowers, Instead Helped Them “Flourish”

(p. A10) The whimsical image fit when the state of Vermont announced last month that a plant thought to be locally extinct — false mermaid-weed — had been found through a chain of events that seemed stolen from a fairy tale.

It began with a sharp-eyed turtle biologist for the state, Molly Parren. She had been out surveying the habitat of wood turtles in rural Addison County on May 7 [2024] when she spotted some wild meadow garlic, which is extremely rare, beside a stream. Ms. Parren snapped a photo and sent it to her colleague, Grace Glynn, Vermont’s state botanist.

But when Ms. Glynn opened the photo, another plant, visible in the foreground, seized her attention. She knew at once what it was: Floerkea proserpinacoides, or false mermaid-weed, an herb that had not been documented in Vermont for more than a century, and one that Ms. Glynn had sought in vain for years.

. . .

The day after the false mermaid-weed was spotted, Ms. Glynn rushed to the rural site to confirm its presence in person. She found a dense carpet — “so many plants, it was hard to imagine how they had been overlooked,” she said.

And yet her disbelief was familiar. “It happens a lot, people saying, ‘We couldn’t have missed that,’” she said. “But we do, and we’re humbled over and over — I love that.”

Far from an anomaly, rediscoveries of plants thought to be extinct are a relatively regular feature of field botany.

. . .

Tricky as it is to find elusive species, it is harder to pinpoint why they thrive or dwindle, and how such shifts might be related to a changing climate. Flooding is cited as one possible factor in the disappearance of false mermaid-weed from Vermont. And yet flooding in the state last summer may have helped it flourish by the stream where it was found, Ms. Glynn said, by depositing sediment and creating a more hospitable habitat.
