Wind Power “Is Not so Clean and Not so Green”

(p. 4B) WALNUT, Iowa (AP) — At a western Iowa wind farm, a demolition crew saws through red slashes marked on 120-foot turbine blades, cutting them into thirds before stuffing the thinnest piece inside the base’s hollow cavity, making more room on a flatbed trailer.

The work is part of MidAmerican Energy’s efforts to “repower” almost 110 turbines, updating towers with longer blades, new hubs and refurbished generators.

. . .

MidAmerican’s retired blades, destined for the Butler County Landfill near David City, Nebraska, about 130 miles away, are among hundreds that will land in dumps across Iowa and the nation. Critics say the blades’ march to a landfill weakens the claim that wind is an environmentally friendly energy source.

“This clean, green energy is not so clean and not so green,” said Julie Kuntz, who opposes a wind project in Worth County in north-central Iowa. “It’s just more waste going in our landfills.”

. . .

The difficulty in reusing blades adds to the complaints of wind energy opponents. Some who live near the turbines complain that low-frequency noise and flickering light from the blades make them ill. And the spinning blades can kill migrating birds and bats.

Napa Vineyards Adapting to Global Warming

(p. D8) Few in Napa Valley feel the urgency to address climate change more than Beth Novak Milliken, president and chief executive of Spottswoode, a family estate that makes superb cabernet sauvignons here on the western edge of St. Helena.

. . .

Ms. Milliken and Aron Weinkauf, the winemaker and vineyard manager, are experimenting with rootstocks that might do better in drought conditions, and grapes like alicante bouschet, mourvèdre and touriga nacional that, as Napa warms, might be blended with cabernet sauvignon to maintain freshness, structure and acidity.

. . .

Like Ms. Milliken, Larkmead is experimenting with different grapes. Mr. Petroski has already initiated a study, planting three acres with a variety of grapes like touriga nacional, tempranillo and aglianico to determine over the next 30 years what might be better able to withstand a hotter environment than cabernet sauvignon.

“I just want people to think that Napa Valley makes great, delicious California-style wines,” he said. “If this is a great vineyard site, it will grow great grapes. It doesn’t have to be only cabernet or merlot.”

“Climate Change Has Been Good for Us”

(p. A1) SLINDE, Norway—Perched on a steep slope overlooking the country’s largest fiord, tidy rows of vines spread on the frosted ground underneath towering pine trees.

On the 61st parallel—the latitude of Anchorage, Alaska— Bjorn Bergum’s vineyard is set to become the world’s northernmost commercial wine estate, a testimony to how global warming is disrupting century-old landscapes, traditions and oenological preconceptions.

“There is no doubt,” Mr. Bergum says. “Climate change has been good for us.”

. . .

(p. A9) “First we take Scandinavia, then the world,” says Erik Lindås, head of Norway’s nascent winegrowers association. “It’s motivating to work when people think you can’t make it. People laughed at English wine 15 years ago but they are not laughing anymore.”

Denmark and Sweden are commercially producing wines that have won international awards, while Britain and Belgium are experiencing a viticultural renaissance. Vintners in Germany, which has a proud winemaking tradition in the south, are exploring new terroirs farther north.

. . .

The northerners have a replique to southern arguments about boreal vineyards’ lack of tradition: During the so-called Medieval Climate Optimum, a warm spell from the ninth century to the 13th, winemaking thrived as far up as northern England and the Baltics.

Professor Hans R. Schultz, who studies climate change’s effects on viticulture at Germany’s Geisenheim University, says global warming is pulling the winemaking economy northward. In Germany’s terroirs, which used to lose entire harvests to cold spells, every vintage since 1987 was better than the previous, he says.

Regenerative Farming Practices “Could Soak Up Half to 100% of All the Carbon Dioxide Emitted”

(p. A2) AINSWORTH, Iowa—What if there was a way to combat climate change that didn’t require technological breakthroughs, carbon taxes or eliminating all fossil fuels?

Such a solution might lie here in an Iowa cornfield beneath the feet of Mitchell Hora, a seventh-generation farmer. Mr. Hora experiments with “regenerative growing practices” that improve soil health, boost yields, reduce water and fertilizer use, and carry a significant collateral benefit: they sequester in the soil carbon released from burning fossil fuels.

Mr. Hora could soon be rewarded for providing this social benefit. Indigo Ag Inc., a Boston-based company specializing in agricultural technology and management, is setting up a market for carbon credits. Companies and consumers with voluntary or compulsory commitments to reduce their carbon footprint can, rather than reduce emissions themselves, pay farmers to do it for them. Via the Indigo Carbon marketplace, they can pay farmers like Mr. Hora $15 to sequester one metric ton of carbon dioxide in the soil.

. . .

David Perry, Indigo’s chief executive, is almost messianic about the potential: “We could soak up half to 100% of all the carbon dioxide emitted since the industrial revolution,” or roughly one trillion tons.

The Rodale Institute, a think tank that promotes organic agriculture and has partnered with Indigo, cites trials that suggest through regenerative growing practices, an acre of agricultural land can sequester one to 2.6 tons of carbon dioxide a year. Extrapolating to the world, that equals the about 37 billion metric tons of carbon dioxide released globally through fossil fuel use each year.

Consumers May Again Be Free to Choose an Incandescent Bulb

(p. A1) The Trump administration plans to significantly weaken federal rules that would have forced Americans to use much more energy-efficient light bulbs, a move that could contribute to greenhouse gas emissions that cause global warming.

The proposed changes would eliminate requirements that effectively meant that most light bulbs sold in the United States — not only the familiar, pear-shaped ones, but several other styles as well — must be either LEDs or fluorescent to meet new efficiency standards.

The rules being weakened, which dated from 2007 and the administration of President George W. Bush and slated to start in the new year, would have all but ended the era of the incandescent bulb invented more than a century ago.

. . .

The Trump administration said the changes would benefit consumers by keeping prices low and eliminating government regulation.

Guacamole “Toast-Munching Hipsters” Can Relax: Gene Edited Avocados Would Thrive Under Global Warming

(p. B1) Last month, a team of scientists in the United States and Mexico announced that it had mapped the DNA sequences of several types of avocados, including the popular Hass variety. That research is likely to become the foundation for breeding techniques and genetic modifications designed to produce avocados that can resist disease or survive in drier conditions.

Whether they realize it or not, this could be big news for toast-munching hipsters. Already, rising temperatures are disrupting the avocado supply chain, causing price increases across the United States that have also been exacerbated by trade uncertainty.

“Because of climate change, temperature might not be the same, humidity might not be the same, the soil might be different, new insects will come and diseases will come,” said Luis Herrera-Estrella, a plant genomics professor at Texas Tech University who led the avocado project. “We need to be prepared to contend with all these inevitable challenges.”

. . .

(p. B5) “There are avocados that grow in very hot places with little water, and there are avocados that grow more in rainy places,” Dr. Herrera-Estrella said. “If we can identify genes that confer heat tolerance and drought tolerance, then we can engineer the avocados for the future.”

Environmentalist Greta Thunberg’s Sailboat Crew Flew to and from New York by Airplane

(p. B4) A year ago, a 15-year-old in leopard-print tights sat down outside the Swedish Parliament building with a purple backpack and a sign announcing she was on strike over climate change.

This week, Greta Thunberg arrived by solar-powered sailboat in New York, now as the 16-year-old poster child for younger generations’ climate angst. Also making its way to the New World, as evidenced in the coverage of her carbon-neutral trip, was a concept that in just a few years has swept Europe: flight shame, often hashtagged in the original Swedish, #flygskam.

. . .

As Greta . . . hopped ashore in southern Manhattan on Wednesday after 13 days at sea, loud cheers rose from the hundreds in the crowd there to greet her.  . . .

Amanda LaValle, a mother of three from Kingston, N.Y., brought her two eldest daughters to be part of the crowd. “I’m encouraging them to be involved. I have already blown my own climate credentials by having three kids,” she said, half in jest.

She acknowledged how difficult it can be to put her principles into practice. Earlier in August, when she needed to travel to Minneapolis for a three-day training sponsored by Al Gore’s Climate Reality Project, she briefly considered taking the train. But, she said, “It would have taken two days and I couldn’t see taking more time away from my family.”

Greta’s voyage has had its own critics, who have pointed out that some members of the sailing crew will return by plane, while others fly in to sail the boat back to Europe.

Boris Herrmann, captain of the sailboat, Malizia II, said that the criticism was expected but that Greta shouldn’t be held responsible for the flights by crew members. “We are kind of the ferry to bring her over. We’re a professional sailing team and sometimes we need to fly. We used this voyage also to train,” he said, adding that the team offsets its flights by funding sustainability projects, including mangrove planting in Indonesia. “The trip is an example of how difficult it is to have zero carbon impact.”

Regulations Mandate Ineffective Dishwashers

(p. A18) The FreedomWorks regulatory policy manager, Daniel Savickas, said the Competitive Enterprise Institute had flagged the dishwasher issue and the groups had decided to combine their efforts. “We try and roll back burdensome regulations and make life easier for consumers and manufacturers,” he said.

“The dishwasher in my apartment is absolute garbage, and I have to run cycles multiple times,” Mr. Savickas said.

The crux of their argument is that energy efficiency standards have made America’s dishwashers ineffective with ever-longer cycles, to the consternation of users. “Why should the government mandate these models rather than leave the choice to consumers in the first place?” Mr. Kazman said.

Sand from Greenland’s Global Warming Can Help World Make Concrete

(p. A8) A few miles up the Sermilik Fjord in southwestern Greenland, the water has abruptly turned milky, a sign that it is loaded with suspended silt, sand and other sediment.

It is this material — carried here in a constant plume of meltwater from the Sermeq glacier at the head of the fjord — that Mette Bendixen, a Danish scientist at the University of Colorado, has come to see. As their research boat moves farther into the murky water, she and several colleagues climb into a rubber dinghy to take samples.

Dr. Bendixen, a geomorphologist, is here to investigate an idea, one that she initially ran by colleagues to make sure it wasn’t crazy: Could this island, population 57,000, become a provider of sand to billions of people?

Sand for eroded beaches, potentially from the Rockaways to the Riviera. Sand to be used as bedding for pipes, cables and other underground infrastructure. Mostly, though, sand for concrete, to build the houses, highways and harbors of a growing world.

The world makes a lot of concrete, more than 10 billion tons a year, and is poised to make much more for a population that is forecast to grow by more than 25 percent by 2050. That makes sand, which is about 40 percent of concrete by weight, one of the most-used commodities in the world, and one that is becoming harder to come by in some regions.

But because of the erosive power of ice, there is a lot of sand in Greenland. And with climate change accelerating the melting of Greenland’s mile-thick ice sheet — a recent study found that melting has increased sixfold since the 1980s — there is going to be a lot more.

“It’s not rocket science,” Dr. Bendixen said. “One part of the world has something that other parts of the world are lacking.”

Gardeners Describe Benefits of Global Warming

(p. A15) When Times readers were asked to describe how they saw climate change affecting their area, several people reported that they were already changing their planting habits due to balmier winter conditions.

“I am now able to grow perennials that were once two temperate zones south of me,” wrote William Borucki, of Buffalo.

Raynard Vinson, of Hampton, Va., wrote: “I overwinter plants that once had to be dug up and protected.”

Forecasts “of Doom and Gloom” Fail Because “Lot of Moving Parts That Are Not Well Understood”

(p. A3) The science community now believes tornadoes most likely build from the ground up and not from a storm cloud down, potentially making them harder to spot via radar early in the formation process. But scientists still struggle to say with certainty when and where a tornado will form, or why some storms spawn them and neighboring storms don’t.

“Sometimes the science and the atmosphere remind us of the limitations of what we can predict,” said Bill Bunting, chief of forecast operations at the National Oceanic and Atmospheric Administration’s Storm Prediction Center.

. . .

“We have big outlooks of doom and gloom, and nothing happens because there are a lot of moving parts that are not well understood yet,” said Erik Rasmussen, a research scientist with NOAA’s National Severe Storms Laboratory.
