UNL Ph.D. Studies Cow Manure and Burps “to Help Save the Planet”

(p. A1) ITHACA, Neb. — In what’s been dubbed the “methane barn” at a University of Nebraska-Lincoln agricultural research center near here, sensitive electronic equipment monitors and logs the amount of gas belched out by a herd of yearling steers.

Yes, Andrea Watson and her fellow UNL scientists are studying cow burps. She has already heard all the jokes.

“My brother especially thinks it’s funny I had to get a Ph.D. to study cow manure and cow burps,” she said.

But this work is really quite serious. If it can help reduce the beef industry’s global environmental hoofprint, it could one day help save the planet.

. . .

Consider that in a year, the average cow belches out 220 pounds of greenhouse gas. According to United Nations figures, if the world’s beef and dairy cattle were their own country, they would be the third-largest emitter, after only China and the United States.

. . .

(p. A9) “Trying to blame the cow industry for any of this is BS,” said Jay Wolf, an Albion, Nebraska, cattle rancher who definitely is familiar with real BS. “We have reduced the herd by one-third. When other sources reduce by one-third, come talk to me.”

. . .

Climate experts are increasingly recognizing that in the decades-long battle ahead, reducing methane emissions from all sources is crucial to helping the planet buy time and avoid catastrophe. Cattle can play a big role in that, said Joe Rudek, lead senior scientist with the Environmental Defense Fund.

. . .

(p. A11) In North America, livestock are responsible for 28% of all methane emissions, with an additional 41% from the oil and gas industry (mostly through leaks) and 21% from landfills. In all, a hefty 25% of today’s warming globally is driven by methane.

Rudek said if methane emissions across all industries worldwide can be cut by 30% by 2050, it would be enough to avoid a half degree of warming.

Many Plants and Animals Quickly Adapt to Global Warming

(p. A15) Amid the ice floes of the Arctic, tiny seabirds called dovekies feed in the plankton-rich waters, a survival strategy that worked well until the pack ice began to dwindle around the islands in Russia’s Franz Josef Land, where the dovekies breed. Like their Arctic neighbors the polar bears, often seen stranded on shrinking icebergs, it appeared that the dovekies faced an existential threat because of climate change. Scientists working in the region predicted that they would have to fly an hour or more to find food.

Instead, data from radio-tagged birds have revealed something entirely different: Faced with the prospect of extinction, the dovekies adapted. They were able to pivot to a new foraging opportunity a five-minute flight away, where water from melting glaciers slams into ocean currents just offshore, making plankton there easy pickings. For now, the dovekie population is thriving, producing just as many healthy chicks as before. Unfortunately, this tactic is not a permanent solution, as Arctic glaciers are dwindling too. But it could buy the birds another century to try to adjust their survival strategy again.

The Franz Josef dovekies remind us that nature is not a passive bystander to climate change. In some surprising cases, new conditions can trigger new behaviors.

. . .

When a group of biologists recently fanned out across the eastern Pacific to study aggression in butterfly fish, they expected to witness the constant territorial skirmishes for which these feisty coral reef dwellers are famous. Then a marine heat wave caused the corals to expel their algae, a damaging process called bleaching that leaves once-colorful reefs ghostly pale and lacking in nutrients for fish.

Suddenly without meals worth fighting for, the butterfly fish changed too. They transformed from aggressors into pacifists almost overnight, becoming docile to save energy and eke out an existence, albeit a subdued one, in a calorie-starved environment. If the corals ever recover, then the fish may regain their previous territorial vigor. If not, then they’ll no longer be famous for defending their food; they’ll be too busy trying to find enough of it.

Butterfly fish and dovekies both employ what biologists call “plasticity,” a natural ability to be flexible.

. . .

Warmer temperatures are forcing conifers to shift northward, while many hardwoods are moving north and west, chasing increases in rainfall. But the direction of these shifts isn’t nearly as surprising as their speed. Red oaks like those at Walden Pond are lumbering north by more than 10 miles every decade, which is nothing next to the 40-mile pace set by honey locusts. Both are shifting considerably faster than the range of the average bird: . . .

. . .

When back-to-back hurricanes Irma and Maria battered the Turks and Caicos Islands in 2017, they flattened buildings, uprooted trees and left the community reeling. They also created a rare scientific opportunity. Surveys of a local species of anole—a distant cousin of iguanas—had just been completed prior to the storms. The researchers had intended to show the effects of predation on the lizards by non-native rats. Instead, they turned their attention to the impact of the hurricanes and immediately repeated their field work. What they found was survival of the fittest in action: Lizards in the post-storm population all had larger toe pads and stronger front legs better suited to gripping trees in high winds. And those traits were being passed on to the next generation.

While scientists expected to eventually see evolution in reaction to extreme weather, many were stunned that it could happen so fast. Understanding how some species adapt in various ways, while others can’t, may help to inform our own responses to climate change. Plasticity may become an unavoidable priority in preparing for a warmer world.

Malnutrition of Poor Is Reduced More by Economic Growth Than by Ending Climate Change

Source of graph: online version of WSJ commentary quoted below.

(p. A17) The Paris climate agreement is projected to keep 11 million more people in poverty come 2030 than otherwise would be. If the Glasgow climate conference in November leads to the adoption of much stronger climate measures, policy makers will raise that total to 80 million additional people in poverty by 2030, which will inevitably cause even more malnutrition deaths.

Climate change deserves our attention, but policy makers need to be realistic. What really protects the world’s poor from malnutrition is getting out of poverty. It’s not expensive climate regulations.

$80 Billion in 200 Large Projects to Develop Hydrogen as Clean Energy Source

(p. B1) SHEFFIELD, England — Rachel Smith has lived through green hydrogen’s bumpy journey from scientists’ dream to an industry that may be on the verge of a commercial breakthrough. An engineer, she started out two decades ago working in a converted barn on early devices for making the clean-burning gas.

Now she is part of a team racing to build giant machines that will use electricity to separate hydrogen from water for major companies like Royal Dutch Shell and Orsted, the Danish offshore wind developer.

“We have gone through those toddler years,” said Ms. Smith, an executive director at ITM Power, which is run out of an expansive new factory in Sheffield, a faded center for steel mills and coal mining. “We are playing in the grown-up world rather than in research labs.”

A consensus is forming among governments, environmentalists and energy companies that deep cuts in carbon emissions will require large amounts of a clean fuel like hydrogen.

Proponents of hydrogen have identified more than a score of potential applications of the element for cutting carbon emissions. It could be used to power long-haul trucks and train and air travel. Energy companies are experimenting with blending hydrogen with natural gas for home heating and cooking.

All told, more than 200 large-scale projects are underway to produce or transport hydrogen, comprising investments of more than $80 billion. Daimler and Volvo, the world’s largest truck makers, plan in a few years to begin mass producing long-haul electric trucks that run on devices called fuel cells that convert hydrogen to electricity. Water will be the trucks’ only emission.

“You could imagine an economy that is supported almost entirely by very clean electricity and very clean hydrogen,” said Ernest Moniz, secretary of energy in the Obama administration and now chief executive of the Energy Futures Initiative, a research organization.

(p. B5) But he warned that “a lot of things have to happen” for a gas now mainly used in specialty areas to become a “part of the backbone of the energy system.”

Among the obstacles that must be overcome: creating enough of the right sort of hydrogen, at a price industries and consumers can accept.

Wind Turbines Kill Up to a Half Million Birds a Year

(p. A4) President Biden has taken steps to restore criminal penalties for accidental killing of migratory birds, a move that if adopted as expected later this year would add pressure to wind power developers who are working to fulfill his mandate to boost wind-farm developments as sources of clean energy.

Wind turbines—some with 200-foot blades spinning up to 180 mph—are estimated to kill between 140,000 and 500,000 birds a year through accidental collisions, according to the U.S. Fish and Wildlife Service.

The wide variation in the estimate reflects the difficulty in tracking bird deaths, but whatever the toll, it is expected to rise as more wind turbines are built. Wildlife researchers in 2013 estimated that the Energy Department’s 2008 wind-power target would push bird deaths to about 1.4 million annually. That figure hasn’t been updated to reflect the Biden administration’s plans to expand offshore wind farms.

French Regulators Ban Hardy Grapes that Thrive in Global Warming

(p. A4) BEAUMONT, France — The vines were once demonized for causing madness and blindness, and had been banned decades ago. The French authorities, brandishing money and sanctions, nearly wiped them out.

But there they were. On a hillside off a winding mountain road in a lost corner of southern France, the forbidden crop was thriving. Early one recent evening, Hervé Garnier inspected his field with relief.

In a year when an April frost and disease have decimated France’s overall wine production, Mr. Garnier’s grapes — an American hybrid variety named jacquez, banned by the French government since 1934 — were already turning red. Barring an early-autumn cold snap, all was on track for a new vintage.

“There’s really no reason for its prohibition,” Mr. Garnier said. “Prohibited? I’d like to understand why, especially when you see the prohibition rests on nothing.”

Mr. Garnier is one of the last stragglers in a long-running struggle against the French wine establishment and its allies in Paris. The French government has tried to rip the jacquez and five other American vine varieties out of French soil for the past 87 years, arguing that they are bad for human physical and mental health — and produce bad wine.

But in recent years, the hardiness of the American varieties has given a lift to guerrilla winemakers like him, as climate change wreaks havoc on vineyards across Europe and natural wines made without the use of pesticides have grown in popularity.

. . .

With France awash in wine, lawmakers urgently addressed the problem around Christmas in 1934. To reduce overproduction, they outlawed the six American vines — including hybrids like the jacquez and pure American grapes like the isabelle — mainly on the grounds that they produced poor wine. Production for private consumption would be tolerated, but not for commercial sale.

The government had planned to follow up with bans on other hybrids but stopped because of the backlash to the initial ban, Mr. Lacombe said. Then the war provided another reprieve.

It was only in the 1950s — when hybrids were still cultivated on a third of all French vineyards — that the government really began cracking down on the six forbidden grapes, Mr. Lacombe said. It offered incentives to rip out the offending vines, then threatened growers with fines.

It then condemned the American grapes as harmful to body and sanity with arguments “not completely honest to try to quell a situation that was slipping away from the government,” Mr. Lacombe said.

“In fact, the present defenders of these vines are right in underlining all the historical and government inconsistencies,” he added.

. . .

Originally from northeastern France, Mr. Garnier, now 68, was once a longhaired high school student who traveled to see Jimi Hendrix, The Who and Janis Joplin perform in concert.

. . .

Some years later, he got into winemaking almost by accident. Two elderly brothers asked him to harvest their jacquez grapes in return for half of the wine production. He learned the history of the forbidden vines and eventually bought the brothers’ vineyards.

Today, he makes 3,400 bottles a year of his deeply colored, fruity “Cuvée des vignes d’antan,” or wine from vines of yesteryear. He got around the ban by creating a cultural, noncommercial association, “Memory of the Vine.” A membership fee of 10 euros, or about $12, yields a bottle.

With the growing threat of climate change and the backlash against the use of pesticides, Mr. Garnier is hoping that the forbidden grapes will be legalized and that France’s wine industry will open up to a new generation of hybrids — as Germany, Switzerland and other European nations already have.

“France is a great wine country,” he said. “To remain one, we have to open up. We can’t get stuck on what we already know.”

E.U. Blocks Innovations in Charger Port Technology

(p. B1) The European Union unveiled plans on Thursday [September 23, 2021] to make USB-C connectors the standard charging port for all smartphones, tablets and other electronic devices sold across the bloc, an initiative that it says will reduce environmental waste but that is likely to hit Apple the hardest.

The move would represent a long-awaited yet aggressive step into product-making decisions by the European Commission, the bloc’s executive arm. Apple, whose iPhones are equipped with a different port, has long opposed the plan, arguing that it would stifle innovation and lead to more electronic waste as all current chargers that are not USB-C would become obsolete.

. . .

(p. B6) European Union officials and lawmakers at the European Parliament have been advocating a common charger since 2009, when there were more than 30 charging options on the market, now down to three. They have argued that fewer wires would be more convenient for users and better for the environment, as mobile phone chargers are responsible for 11,000 tons of electronic waste per year across the bloc, according to estimates by the European Commission.

But Apple has also argued that if the European Union had imposed a common charger in 2009, it would have restricted innovation that led to USB-C and Lightning connectors. In a statement, Apple said that although it welcomed the European Commission’s commitment to protecting the environment, it favored a solution that left the device side of the charging interface open for innovation.

Central Planners’ Electric-Vehicle Push Is “More Political Showmanship Than Sound Planning”

(p. A1) The Toyota Prius hybrid was a milestone in the history of clean cars, attracting millions of buyers worldwide who could do their part for the environment while saving money on gasoline.

But in recent months, Toyota, one of the world’s largest automakers, has quietly become the industry’s strongest voice opposing an all-out transition to electric vehicles — which proponents say is critical to fighting climate change.

. . .

(p. A9) In statements, Toyota said that it was in no way opposed to electric vehicles. “We agree and embrace the fact that all-electric vehicles are the future,” Eric Booth, a Toyota spokesman, said. But Toyota thinks that “too little attention is being paid to what happens between today, when 98 percent of the cars and trucks sold are powered at least in part by gasoline, and that fully electrified future,” he said.

Until then, Mr. Booth said, it makes sense for Toyota to lean on its existing hybrid and plug-in hybrid vehicles to reduce emissions. Hydrogen fuel cell technology should also play a role. And any efficiency standards should “be informed by what technology can realistically deliver and help keep vehicles affordable,” the company said in a statement.

. . .

On paper, Toyota’s approach to zero-emissions vehicles, the hydrogen fuel cell, is a dream: Unlike battery-powered electric vehicles, these cars carry hydrogen tanks and fuel cells that turn the hydrogen into electricity. They refuel and accelerate quickly, and can travel for several hundred miles on a tank, emitting only water vapor. And hydrogen, theoretically, is abundant.

But a high sticker price, as well as lack of refueling infrastructure, has hampered the growth of a hydrogen economy, at least for passenger cars.

. . .

Jeffrey K. Liker, professor emeritus of industrial and operations engineering at the University of Michigan and author of “The Toyota Way,” said that there were other factors slowing Toyota’s push. A famously cautious company, Toyota has researched solid-state batteries, which are safer than the widely used lithium-ion technology, but readying that technology has taken longer than they expected, he said. Toyota has also spoken about not wanting to lay off employees or bankrupt suppliers in a rapid transition to electrics.

“Toyota’s view is also that countries are jumping in with the idea of the electric-vehicle endgame without a real plan, and it’s more political showmanship than sound planning,” Mr. Liker said.

Rivian Entrepreneur Is “Starkly Different” From Elon Musk, but Both “Are Immersed in the Details of Their Business”

(p. B5) Rivian, a promising and well-funded electric truck maker, plans to sell shares through an initial public offering, the company said Friday [Aug. 27, 2021], just weeks before it expects to deliver its first electric pickups to customers.

. . .

“Rivian is one of the best-positioned electric vehicle start-ups,” Asad Hussain, senior mobility analyst for PitchBook, said by email. “The company’s focus on the relatively untapped premium electric truck market should allow it to gain rapid market adoption.”

The leaders of Rivian and Tesla are also starkly different. Tesla’s chief executive, Elon Musk, has been a brash and combative force in the automotive industry, making big promises and engaging in public feuds with individuals and government agencies. Mr. Scaringe is understated and has been measured in his public statements and promises.

Still, both executives are immersed in the details of their business. Mr. Musk has said he has slept at his company’s main factory in Fremont, Calif., at important moments when Tesla was ramping up production. Mr. Scaringe is also a frequent presence at Rivian’s factory in Normal, Ill., and workers there refer to the color of robots and safety lines directing the flow of people as “R.J. Blue.” He has been known to weigh in on vehicle colors, including one known as “launch green.”

. . .

“In the very beginning, on Day 1, Year 1, the risk of starting a business like this is enormously high, and the likelihood of success was very low,” he said. “That’s just true. And I had to accept that.”

But Mr. Scaringe said he remained confident in his team and in the strategic plan they had assembled: First, raise enough money to develop core technologies — software, battery architecture, mechanical systems — that could support vehicles for both consumers and commercial customers; then raise more capital to mass produce trucks and vans.

Rivian appeared to embark on that second phase a few years ago. In the fall of 2018, Jeff Bezos, the Amazon founder, flew to Michigan to meet Mr. Scaringe and preview the company’s vehicles. By the end of the next year, Rivian had raised nearly $3 billion from investors including Ford and Amazon, which also ordered 100,000 delivery vans.

Global Warming Makes This “An Exciting Time if You’re a Wine Lover”

(p. B6) . . . rising temperatures have had . . . unforeseen effects. Parts of the United Kingdom, a country not at all known for wine production, are now making sparkling wine — as they did back in Roman times.

For wine connoisseurs, that means changes in the types of wines they’ve long loved and where those wines are produced. The average consumer may not notice but the seemingly stable world of wine has become anything but.

“We’re seeing a broader selection of very interesting wines because of this warming,” said Dave Parker, founder and chief executive of the Benchmark Wine Group, a large retailer of vintage wines. “We’re seeing regions that historically were not that highly thought of now producing some excellent wines. The U.K., Oregon, New Zealand or Austria may have been marginal before but they’re producing great wines now. It’s kind of an exciting time if you’re a wine lover.”

The rising temperatures have certainly hurt some winemakers, but in some wine-growing areas the heat has been a boon for vineyards and the drinkers who covet their wine. Mr. Parker said growing conditions for sought-after vintages in Bordeaux used to come less frequently and sometimes only once every decade: 1945, 1947, 1961, 1982, 1996 and 2000. They were all very ripe vintages, because of the heat. But in the last decade, with temperatures rising in Bordeaux, wines from 2012, 2015, 2016, 2018, and 2019 are all sought after — and highly priced.

And then, there are the wines from previously overlooked regions.

“What I’d say is, currently, there hasn’t been a better time for wine collectors,” said Axel Heinz, the estate director of Ornellaia and Masseto, two of Italy’s premier wines. “The vintages and wine have become so much better. And for us, the changes over the past 20 years have put a focus on many growing regions that collectors weren’t interested in before, like Italian and Spanish wine.”

“Extrapolate to Doomsday”

(p. B1) The giant tech companies with their power-hungry, football-field-size data centers are not the environmental villains they are sometimes portrayed to be on social media and elsewhere.

Shutting off your Zoom camera or throttling your Netflix service to lower-definition viewing does not yield a big saving in energy use, contrary to what some people have claimed.

Even the predicted environmental impact of Bitcoin, which does require lots of computing firepower, has been considerably exaggerated by some researchers.

Those are the conclusions of a new analysis by Jonathan Koomey and Eric Masanet, two leading scientists in the field of technology, energy use and the environment. Mr. Koomey is now an independent analyst, and Mr. Masanet is a professor at the University of California, Santa Barbara. (Mr. Masanet receives research funding from Amazon.)

They said their analysis, published on Thursday [June 24, 2021] as a commentary article in Joule, a scientific journal, was not necessarily intended to be reassuring. Instead, they said, it is meant to inject a dose of reality into the public discussion of technology’s impact on the environment.

. . .

(p. B3) Exaggerated claims, the pair said, are often well-intentioned efforts by researchers who make what may seem like reasonable assumptions. But they are not familiar with fast-changing computer technology — processing, memory, storage and networks. In making predictions, they tend to underestimate the pace of energy-saving innovation and how the systems work.

. . .

Computer data centers are a case study. The biggest data centers, from which consumers and workers tap services and software over the internet, do consume huge amounts of electricity. These so-called cloud data centers are operated by companies including Alibaba, Amazon, Apple, Facebook, Google and Microsoft.

From 2010 to 2018, the data workloads hosted by the cloud data centers increased 2,600 percent and energy consumption increased 500 percent. But energy consumption for all data centers rose less than 10 percent.

What happened, the authors explain, was mainly a huge shift of workloads to the bigger, more efficient cloud data centers — and away from traditional computer centers, largely owned and run by non-tech companies.

In 2010, an estimated 79 percent of data center computing was done in traditional computer centers. By 2018, 89 percent of data center computing took place in cloud data centers.

“The big cloud providers displaced vastly less efficient corporate data centers,” Mr. Koomey said. “You have to look at the whole system and take substitution effects into account.”

The complexity, dynamism and unpredictability of technology development and markets, the authors say, make projecting out more than two or three years suspect. They critiqued a Bitcoin energy paper that projected out decades, based on what they said were old data and simplified assumptions — an approach Mr. Masanet called “extrapolate to Doomsday.”
