Plastic in Oceans Is Only One-Sixteenth of Previously Publicized Estimate

(p. A7) There’s less plastic pollution flowing into the ocean from land than scientists previously thought, according to a study published Monday in the journal Nature Geoscience.

The researchers estimated that about 500,000 metric tons of plastic end up in the ocean each year, with about half from land. The other half comes from the fishing industry in the form of nets, ropes, buoys and other equipment.

An earlier, widely publicized study in 2015 estimated that about eight million metric tons of plastic were entering the ocean each year from rivers alone.

. . .

The 2015 study was one of the first comprehensive research efforts to tally up how much plastic ends up in the ocean. But there was a large discrepancy between its estimate of eight million metric tons and the amount of plastic observed in the ocean. Newer studies have tried to address this gap.

The paper published on Monday [Aug. 7, 2023] combined data from many earlier studies that sampled smaller plastics in the ocean using net trawls or observed larger plastics from ships and from shore. The researchers fed this data into a computer model of how objects move around the ocean in order to estimate both how much plastic is entering the ocean each year and how much total plastic pollution there is floating on the sea surface.

The “Deliciously Guilty Pleasure” and “Disorienting Joy” of California Skiing in August

(p. A20) This weekend, . . . hordes of Californians are smearing pink and yellow zinc oxide on noses, shoving feet into hard plastic ski boots and gliding over to the lifts at Mammoth Mountain for yet another day on the slopes. A reminder: It’s August.

. . .

Unpredictable change is the new status quo.  . . . it can also, in a rare instance like the chance to ski in the dog days of summer, bring a disorienting joy.

. . .

In mid-July [2023], well after all the hot dogs and fireworks, I headed up to the Sierra and ran into so much lingering snow that the road through Yosemite National Park hadn’t yet opened for the season. I took an alternate route, 108 over Sonora Pass, and saw people parking in turnouts, carrying skis up dirt trails through trees, stepping onto sunny snow slopes and linking turns back down to ice chests full of cold drinks before, you know, maybe going for a swim. When I finally got to Kelly’s place, the creek on her high desert property frothed in a fabulous white and clear torrent through sage lands sparkling with superblooming yellow mule’s ear, red paintbrush and white phlox. The big peaks, meanwhile — in the dead heat of a California summer — remained so heavily blanketed in snow that I felt I was seeing them the way Indigenous people must have during the Little Ice Age, 500 years ago.

The premise of California’s secular faith in nature is that water plus sunshine equals enlightenment. In high school I was transfixed by a description on the jacket of Bank Wright’s classic “Surfing California” of “skiing Mount Baldy in the morning and surfing Hermosa Beach in the afternoon.” That struck the teenage me as the absolute perfect way of snatching healthy peace and giddy fun from the predictable maw of adult misery.

. . .

. . . when I drove to Mammoth, put on my favorite cowboy hat against the sun and sipped iced coffee while watching tiny black figures ski down blinding white slopes, the experience was perhaps best likened to the queasy adrenalized thrill of an oncoming manic episode after a long and dark depression — worrisome, yes, bound for nowhere good but, as long as we’re just talking here and now, a deliciously guilty pleasure.

Hybrids Appeal to Consumers with Short-Term E.V. “Range Anxiety”

(p. A19) . . . there’s a good argument to be made that the government, and automakers, are leaning too hard into all-electric and neglecting the virtues of hybrid technology. When I first heard this counterintuitive argument from Toyota, I dismissed it as heel-dragging by a company that lags in electrics, but I’ve come around to the idea that hybrids — at least for now — do have a lot of advantages over all-electric vehicles.

. . .

(p. A6) “Toyota’s claim is accurate. We’ve crunched the numbers on this,” Ashley Nunes told me. He is a senior research associate at Harvard Law School and the director for federal policy, climate and energy at the Breakthrough Institute, a think tank. He testified on the topic in April [2023] before the House Subcommittee on Environment, Manufacturing and Critical Materials.

. . . electric vehicles consume huge quantities of lithium and other materials because they have huge batteries. And they have huge batteries because customers suffer from “range anxiety” and won’t buy an E.V. unless it can go for hundreds of miles without charging — even though the vast majority of trips are short.

. . .

Some people will keep driving old ICE-mobiles (cars with internal combustion engines) because they can’t afford an E.V. And those ICE-mobiles will continue to be major emitters of greenhouse gases.

The production of electric vehicles produces more greenhouse gases than the production of cars with combustion engines. So E.V.s have to travel between 28,000 and 68,000 miles before they have an emissions advantage over similarly sized and equipped ICE-mobiles, according to Nunes. That may take 10 years or more if the E.V. isn’t driven much.

Less Fire on World’s Land Since Early 2000s

(p. A15) One of the most common tropes in our increasingly alarmist climate debate is that global warming has set the world on fire. But it hasn’t. For more than two decades, satellites have recorded fires across the planet’s surface. The data are unequivocal: Since the early 2000s, when 3% of the world’s land caught fire, the area burned annually has trended downward.

In 2022, the last year for which there are complete data, the world hit a new record-low of 2.2% burned area. Yet you’ll struggle to find that reported anywhere.

. . .

This summer, the focus has been on Canada’s wildfires, the smoke from which covered large parts of the Northeastern U.S. Both the Canadian prime minister and the White House have blamed climate change.

. . .

In the case of American fires, most of the problem is bad land management. A century of fire suppression has left more fuel for stronger fires. Even so, last year U.S. fires burned less than one-fifth of the average burn in the 1930s and likely only one-tenth of what caught fire in the early 20th century.

When reading headlines about fires, remember the other climate scare tactics that proved duds. Polar bears were once the poster cubs for climate action, yet are now estimated to be more populous than at any time in the past half-century. We were told climate change would produce more hurricanes, yet satellite data shows that the number of hurricanes globally since 1980 has trended slightly downward.

. . .

Surveys repeatedly show that most voters are unwilling to support the very expensive climate policies activists and green politicians have proposed. Overheated headlines about climate Armageddon are an attempt to scare us into supporting them anyway, at the cost of sensible discussion and debate.

Latest High-Efficiency Air Conditioners Focus on Cutting Humidity

(p. B4) Air conditioners make people cooler and the world hotter. A slew of startups are launching new products to break that cycle.

. . .

Companies such as Blue Frontier, Transaera and Montana Technologies are raising money from investors including industry giant Carrier Global and Bill Gates’s Breakthrough Energy Ventures to develop more efficient technologies. Many of those efforts focus on the humidity rather than the heat, using new materials like liquid salt to dry out the air.

. . .

Blue Frontier aims to separate humidity and temperature control using a liquid salt solution that was developed with the National Renewable Energy Laboratory. The solution also stores energy, reducing consumption at peak times, when electricity grids are strained on hot days.

The salt solution is an industrial version of the little packets that absorb moisture to keep products dry during shipping. The solution is heated up, releasing water and boosting the concentration of salt, making it more absorbent. This can be done when electricity demand is low and effectively stores energy until cooling is needed.

When air conditioning is needed, the solution is brought in contact with air, absorbing water and removing humidity. The air is cooled within a component called a heat exchanger using a high-efficiency method to lower air temperature by exposing it to water. The dry air absorbs the water, lowering its temperature and the temperature of the heat exchanger. That air that absorbs the water becomes warm and humid and is moved outside. At the same time, air that moves through the chilled heat exchanger flows into the room that is being cooled.

After raising $20 million from investors including Breakthrough last year, Blue Frontier is trialing ACs for businesses. “Air conditioning could be a solution to the problem rather than being the problem,” Betts said.

. . .

“The climate problem is only going to get worse if we continue to add the same types of air conditioners to meet that demand,” said Sorin Grama, CEO of Transaera, which is developing a new AC using highly absorbent materials that remove humidity. The company raised $4.5 million from investors including Carrier last year and is currently making prototypes.

Grama co-founded Transaera with a Massachusetts Institute of Technology professor after working in India for a refrigeration company and seeing that air conditioners were too expensive for many consumers in the country.

As Worms Return to Arctic, Some Life Forms Will Thrive and Others Will Not

(p. A1) Worms are on the move, and people are nervous.

That’s because they’re taking over territory in the Far North that’s been wormless since the last ice age.

. . .

Because of changes in the chemistry and physics of the ground, grasses and shrubby plants tend to thrive, taking over from tundra mosses and lichens. That’s good news for the lemmings and voles that favor such plants, according to Hanna Jonsson, an ecology researcher at Umea University. But probably not good for other herbivores that might not adapt easily to a change in available food.

New 98% Reflective White Paint Can End Global Warming

(p. A1) In 2020, Dr. Ruan and his team unveiled their creation: a type of white paint that can act as a reflector, bouncing 95 percent of the sun’s rays away from the Earth’s surface, up through the atmosphere and into deep space. A few months later, they announced an even more potent formulation that increased sunlight reflection to 98 percent.

The paint’s properties are almost superheroic. It can make surfaces as much as eight degrees Fahrenheit cooler than ambient air temperatures at midday, and up to 19 degrees cooler at night, reducing temperatures inside build-(p. A12)ings and decreasing air-conditioning needs by as much as 40 percent. It is cool to the touch, even under a blazing sun, Dr. Ruan said. Unlike air-conditioners, the paint doesn’t need any energy to work, and it doesn’t warm the outside air.

. . .

. . ., scientists have been urgently working to develop reflective materials, including different types of coatings and films, that could passively cool the Earth. The materials rely on principles of physics that allow thermal energy to travel from Earth along specific wavelengths through what’s known as the transparency or sky window in the atmosphere, and out into deep space.

Jeremy Munday, a professor of electrical and computer engineering at the University of California, Davis, who researches clean technology, said this redirection would barely affect space. The sun already emits more than a billion times more heat than the Earth, he said, and this method merely reflects heat already generated by the sun. “It’d be like pouring a cup of regular water into the ocean,” Dr. Munday said.

He calculated that if materials such as Purdue’s ultra-white paint were to coat between 1 percent and 2 percent of the Earth’s surface, slightly more than half the size of the Sahara, the planet would no longer absorb more heat than it was emitting, and global temperatures would stop rising.

. . .

While humans in such hot and picturesque places as Santorini and the aptly named Casablanca have long used white paint to cool dwellings, and municipalities are increasingly looking to paint rooftops white, Dr. Ruan said commercial white paints generally reflect 80 percent to 90 percent of sunlight. This means they still absorb 10 percent to 20 percent of the heat, which in turn warms surfaces and the ambient air. The Purdue paint, by comparison, absorbs so much less solar heat and radiates so much more heat into deep space that it cools surfaces to below-ambient temperatures.

Seaweed Blob Disappears as Unpredictably as It First Appeared

(p. 19) For months, Florida’s usually picturesque coast was plagued by a rotting tangle of seaweed, known as sargassum. Then, as quickly as the stinking mass arrived, it began to disappear.

. . .

Last month, the amount of sargassum in the Gulf of Mexico dropped by a staggering 75 percent, Dr. Hu and colleagues at the University of South Florida Optical Oceanography Lab noted in a bulletin published [June 30, 2023].

. . .

But scientists don’t know why the decline was so rapid. One theory is that strong winds caused by recent tropical storms could have dissipated the sargassum into smaller clumps, or sunk it to the ocean floor, Dr. Hu said, making it hard to see from a satellite. “There could be other reasons, we just don’t know,” he added.

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.

With No New Transmission Lines, 80 Percent of Planned Biden Emissions Reduction May Not Happen

(p. A12) . . ., compare today’s renewable energy and transmission system to one estimate of what it would take to reach the Biden administration’s goal of 100 percent clean electricity generation by 2035. Transmission capacity would need to more than double in just over a decade.

There are enormous challenges to building that much transmission, including convoluted permitting processes and potential opposition from local communities.

. . .

The climate stakes are high. Last year, Congress approved hundreds of billions of dollars for solar panels, wind turbines, electric vehicles and other technologies to tackle global warming. But if the United States can’t build new transmission at a faster pace, roughly 80 percent of the emissions reductions expected from that bill might not happen, researchers at the Princeton-led REPEAT Project found.

Already, a lack of transmission capacity means that thousands of proposed wind and solar projects are facing multiyear delays and rising costs to connect to the grid. In many parts of the country, existing power lines are often so clogged that they can’t deliver electricity from wind and solar projects to where it is needed most and demand is often met by more expensive fossil fuel plants closer to homes and businesses. This problem, known as congestion, costs the country billions of dollars per year and has been getting worse.

. . .

Utilities are sometimes wary of long-distance transmission lines that might undercut their local monopolies.

“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.
