Floating Nuclear Power Plants May Be Cheaper, Greener, and Safer

(p. B5) MURMANSK, Russia — Along the shore of Kola Bay in the far northwest of Russia lie bases for the country’s nuclear submarines and icebreakers. Low, rocky hills descend to an industrial waterfront of docks, cranes and railway tracks. Out on the bay, submarines have for decades stalked the azure waters, traveling between their port and the ocean depths.
Here, Russia is conducting an experiment with nuclear power, one that backers say is a leading-edge feat of engineering but that critics call reckless.
The country is unveiling a floating nuclear power plant.
Tied to a wharf in the city of Murmansk, the Akademik Lomonosov rocks gently in the waves. The buoyant facility, made of two miniature reactors of a type used previously on submarines, is for now the only one of its kind.
Moscow, while leading the trend, is far from alone in seeing potential in floating nuclear plants. Two state-backed companies in China are building such facilities, (p. B5) and American scientists have drawn up plans of their own. Proponents say they are cheaper, greener and, perhaps counterintuitively, safer. They envision a future when nuclear power stations bob off the coasts of major cities around the world.
“They are light-years ahead of us,” Jacopo Buongiorno, a professor of nuclear engineering at the Massachusetts Institute of Technology, said of the Russian floating power program.
Rosatom, the Russian state nuclear company, has exported nuclear technology for years, selling plants in China, India and a host of developing nations. But smaller reactors effectively placed on floats can be assembled more quickly, be put in a wider range of locations and respond more nimbly to fluctuating supply on power grids that increasingly rely on wind and solar.
The Russian design involves using submarine-style reactors loaded onto vessels, with a hatch near the bow to plug them into local electrical grids. The reactors will generate a combined 70 megawatts of electricity, or enough to power about 70,000 typical American homes. Rosatom plans to serially produce such floating nuclear plants, and is exploring various business plans, including retaining ownership of the reactors while selling the electricity they generate.

Natural Gas Helps U.S. Reduce Carbon Emissions

(p. A11) BONN, Germany — Industrial emissions of carbon dioxide are projected to rise to record highs in 2017 after a three-year plateau, scientists said Monday [Nov. 13, 2017]. It’s a sign that the world is still far from achieving its goals to limit global warming.
. . .
. . . , after a brief dip last year, China’s emissions are projected to rise approximately 3.5 percent this year. Local governments invested heavily in infrastructure and construction projects to stimulate growth, while unfavorable rainfall patterns have reduced output from the nation’s hydropower dams, said Lauri Myllyvirta, who analyzes China’s energy trends for Greenpeace.
. . .
Much of the fall in American emissions has come as increasing supplies of natural gas, wind and solar power have driven hundreds of coal plants into retirement. .

Affordable Methods for Countering CO2 in Atmosphere

(p. A13) A new study partly funded by Bill Gates has dramatically cut the estimated cost of removing CO2 directly from the air to as little as $100 a ton. According to the study, much of this expense could be recaptured by converting the CO2 into low-carbon motor fuel.
Assume California recovered 80% of its costs. For $500 billion a year, or 20% of state gross domestic product, California could solve the alleged problem for the whole world, reducing global emissions by half and meeting the widely touted goal of holding warming to less than 2 degrees Celsius according to prevailing climate models.
Too speculative? Too expensive? Many classic studies suggest that, at a cost as low as $2 billion a year, any highly motivated actor, even one with pockets less deep than California’s, could offset the entire warming effect of excess CO2 by distributing enough high-altitude sulfates or other aerosol particles to limit by 1% the amount of sunlight reaching the planet’s surface. Indeed, experts quietly acknowledge that, by reducing such particulates, our clean-air efforts have actually made our climate problem worse.

“They Say ‘Yes,’ and We Pay the Price”

(p. A14) ELLENSBURG, Wash. — When a company from Seattle came calling, wanting to lease some land on Jeff and Jackie Brunson’s 1,000-acre hay and oat farm for a solar energy project, they jumped at the idea, and the prospect of receiving regular rent checks.
They did not anticipate the blowback — snarky texts, phone calls from neighbors, and county meetings where support for solar was scant.
. . .
The political power in Washington State, and the agenda for renewable energy and much else, comes from the liberal urban expanse around Seattle, and many people in conservative rural places east of the Cascades, like Kittitas County, chafe at the imbalance.
. . .
Opponents of the solar project have a shorthand line of attack: Seattle is pushing this.
“The wind farms aren’t located in the greater Seattle area, the wolves aren’t located in the greater Seattle area, the grizzly bear expansion isn’t slated for the Greater Seattle area, and the solar farms aren’t there either,” said Paul Jewell, a former county commissioner, ticking off highly debated initiatives that government officials have considered in recent years.
“They’re all in the rural areas,” said Mr. Jewell, who opposes the solar project. “And so there’s really a disconnect there — they say ‘yes,’ and we bear the burden. They say ‘yes,’ and we pay the price.”

Hot Students Learn Less

More evidence on why air conditioning increases our mental acuity:

(p. A5) Hot weather makes it more difficult for high-school students to learn, a new study suggests.
. . .
The study was circulated by the National Bureau of Economic Research as a working paper by Mr. Goodman and three other researchers.
They found that, on average, every increase of 1 degree Fahrenheit in the average temperature during the school year reduced learning by about 1%.

Lack of “Air-Conditioning Can Be Deadly”

(p. A10) The number of air-conditioners worldwide is predicted to soar from 1.6 billion units today to 5.6 billion units by midcentury, according to a report issued Tuesday by the International Energy Agency.
. . .
While 90 percent of American households have air-conditioning, “When we look in fact at the hot countries in the world, in Africa, Asia, Latin America and the Middle East, where about 2.8 billion people live, only about 8 percent of the population owns an air-conditioner,” said Fatih Birol, executive director of the energy agency.
As incomes in those countries rise, however, more people are installing air-conditioners in their homes. The energy agency predicts much of the growth in air-conditioning will occur in India, China and Indonesia.
Some of the spread is simply being driven by a desire for comfort in parts of the world that have always been hot.
. . .
And when it gets hot, forgoing air-conditioning can be deadly. The heat wave that plagued Chicago in 1995 killed more than 700 people, while the 2003 European heat wave and 2010 Russian heat wave killed tens of thousands each.

Ecosocialism: The “Green-and-Red Agenda” to Eradicate Capitalism

Not all environmentalists are motivated by a desire to destroy capitalism. But some are. See below.

(p. 26) Joel Kovel, a former Freudian psychiatrist who evolved into an apostle of what he called ecosocialism, a so-called green-and-red agenda against the environmental evils of globalization and in favor of the nonviolent eradication of capitalism, died on Monday [April 30, 2018] in Manhattan.
. . .
Whenever he launched an ideological crusade, he did so zealously — even if, as in the case of ecosocialism, its very definition and the collateral demand for an appealing alternative to capitalism were not self-evident.
Under ecosocialist theory, income would be guaranteed, most property and means of production would be commonly owned, and the abolition of capitalism, globalism and imperialism would unleash environmentalists to vastly curtail industrialization and development whose pollution would otherwise cause catastrophic global warming.
“Capitalist production, in its endless search for profit, seeks to turn everything into a commodity,” Dr. Kovel wrote in 2007 on the socialist website Climate and Capitalism. “It is plain that production will have to shift from being dominated by exchange — the path of the commodity — to that which is for use, that is for the direct meeting of human needs.”

California Regulation Adds $9,500 to Average Home Cost

(p. A1) The California Energy Commission voted 5-0 to approve a mandate that residential buildings up to three stories high, including single-family homes and condos, be built with solar installations starting in 2020.
The commission estimates that the move, along with other (p. A2) energy-efficiency requirements, would add $9,500 to the average cost of building a home in California. The state is already one of the most expensive housing markets in the country, with a median price of nearly $565,000 for a single-family home, according to the California Association of Realtors.

Hundreds of Years of CO2 Emissions Could Be Stored Forever in Oman’s Rocks

(p. A10) IBRA, Oman — In the arid vastness of this corner of the Arabian Peninsula, out where goats and the occasional camel roam, rocks form the backdrop practically every way you look.
But the stark outcrops and craggy ridges are more than just scenery. Some of these rocks are hard at work, naturally reacting with carbon dioxide from the atmosphere and turning it into stone.
Veins of white carbonate minerals run through slabs of dark rock like fat marbling a steak. Carbonate surrounds pebbles and cobbles, turning ordinary gravel into natural mosaics.
Even pooled spring water that has bubbled up through the rocks reacts with CO2 to produce an ice-like crust of carbonate that, if broken, re-forms within days.
Scientists say that if this natural process, called carbon mineralization, could be harnessed, accelerated and applied inexpensively on a huge scale — admittedly some very big “ifs” — it could help fight climate change. Rocks could remove some of the billions of tons of heat-trapping carbon dioxide that humans have pumped into the air since the beginning of the Industrial Age.
And by turning that CO2 into stone, the rocks in Oman — or in a number of other places around the world that have similar geological formations — would ensure that the gas stayed out of the atmosphere forever.
“Solid carbonate minerals aren’t going anyplace,” said Peter B. Kelemen, a geologist at Columbia University’s Lamont-Doherty Earth Observatory who has been studying the rocks here for more than two decades.
Capturing and storing carbon dioxide is drawing increased interest. The Intergovernmental Panel on Climate Change says that deploying such technology is essential to efforts to rein in global warming.
. . .
The rocks are so extensive, Dr. Kelemen said, that if it was somehow possible to fully use them they could store hundreds of years of CO2 emissions. More realistically, he said, Oman could store at least a billion tons of CO2 annually. (Current yearly worldwide emissions are close to 40 billion tons.)

Global Warming Most Affects Coldest Regions

(p. A11) Winters in the United States have gotten warmer in the past 30 years, and some of the coldest parts of the country have warmed up the most.
In Minnesota, winters between 1989 and 2018 were an average of 3 degrees Fahrenheit warmer, compared to a 20th century baseline, according to data from the National Oceanic and Atmospheric Administration analyzed by The New York Times. Florida’s winters were 1.4 degrees warmer, on average, during that time.
For each 30-year period above, the maps show how much warmer or cooler winters were across the contiguous United States, compared to an average winter for that location during the 20th century. Though it might not always feel like it, warmer winters have become more common across most of the country. The most significant temperature increases can be seen in the Northern Great Plains, a region stretching from Montana to Michigan.
The Northern Great Plains have warmed up particularly quickly in part because of the dry winter conditions typical there, said Kenneth Blumenfeld, a senior climatologist at the Minnesota State Climate Office. Cold air moving into the area from Canada and the Arctic is also not as cold as it used to be, he said.
“In Minnesota, we used to get to negative 30 or negative 40 degrees with certain frequency. But no longer. Maybe we’ll now hit negative 30 with the frequency we used to hit negative 40,” Dr. Blumenfeld said. But, he added, this difference in cold extremes can be difficult for people to perceive. When it’s that cold out, after all, people tend to stay inside.
The pattern of warming shown here is largely consistent with global trends, said Jake Crouch, a scientist at NOAA’s climate monitoring branch. “In general, northern latitudes are warming faster than southern latitudes. Interior locations are warming faster than coastal locations.”
