Geoengineering Could Cheaply and Quickly Counter Global Warming

(p. B1) Last month, scholars from the physical and social sciences who are interested in climate change gathered in Washington to discuss approaches like cooling the planet by shooting aerosols into the stratosphere or whitening clouds to reflect sunlight back into space, which may prove indispensable to prevent the disastrous consequences of warming.
Aerosols could be loaded into military jets, to be sprayed into the atmosphere at (p. B4) high altitude. Clouds at sea could be made more reflective by spraying them with a fine saline mist, drawn from the ocean.
. . .
. . . , geoengineering needs to be addressed not as science fiction, but as a potential part of the future just a few decades down the road.
“Today it is still a taboo, but it is a taboo that is crumbling,” said David Keith, a noted Harvard physicist who was an organizer of the conclave.
. . .
Geoengineering would be cheap enough that even a middle-income country could deploy it unilaterally. Some scientists have estimated that solar radiation management could cool the earth quickly for as little as $5 billion per year or so.

Lower Ivory Prices Reduce Incentives to Poach Elephants

(p. A9) NAIROBI, Kenya — Finally, there’s some good news for elephants.
The price of ivory in China, the world’s biggest market for elephant tusks, has fallen sharply, which may spell a reprieve from the intense poaching of the past decade.
According to a report released on Wednesday [March 29, 2017] by Save the Elephants, a respected wildlife group in Kenya, the price of ivory is less than half of what it was just three years ago, showing that demand is plummeting.

Since 1880 North America Is Warmer by One and a Half Degrees Fahrenheit

(p. A23) Anyone who has read the 2014 report of the Intergovernmental Panel on Climate Change knows that, while the modest (0.85 degrees Celsius, or about 1.5 degrees Fahrenheit) warming of the earth since 1880 is indisputable, as is the human influence on that warming, much else that passes as accepted fact is really a matter of probabilities. That’s especially true of the sophisticated but fallible models and simulations by which scientists attempt to peer into the climate future. To say this isn’t to deny science. It’s to acknowledge it honestly.

Justified Species Extinction

(p. A1) The death toll from diseases carried by mosquitoes is so huge that scientists are working on a radical idea. Why not eradicate them?
Mosquitoes kill more humans than any other animal and were linked to roughly 500,000 deaths in 2015, mostly from malaria. For more than a century, humans have used bed nets, screens and insecticides as weapons, but mosquitoes keep coming back. They are now carrying viruses like Zika and dengue to new parts of the world.
Powerful new gene-editing technologies could allow scientists to program mosquito populations to gradually shrink and die off. Some efforts have gained enough momentum that the possibility of mosquito-species eradication seems tantalizingly real.
“I think it is our moral duty to eliminate this mosquito,” entomologist Zach Adelman says about Aedes aegypti, a species carried afar over centuries by ships from sub-Saharan Africa.
. . .
(p. A8) Purposely engineering a species into extinction–or just diminishing it–is fraught with quandaries. Scientists must weigh the potential impact of removing a species on the environment and food chain. It will take years of more research, testing and regulatory scrutiny before most genetically altered mosquitoes can be released into the wild. And the strategy might not work.
Wiping a species off the face of the earth is “an unfortunate thing to have to do,” says Gregory Kaebnick, a research scholar at the Hastings Center, a bioethics research institute in Garrison, N.Y.
He says humans shouldn’t force a species into extinction to meet their own preferences. “We ought to try not to do it,” says Mr. Kaebnick. One justification, he says, would be to avert a serious public-health threat.

Nano-Enhanced Fabrics Can Clean Themselves

(p. D3) Scientists in Australia, one of the sunniest places on the planet, have discovered a way to rid clothes of stubborn stains by exposing them to sunlight, potentially replacing doing the laundry.
Working in a laboratory, the researchers embedded minute flecks of silver and copper–invisible to the naked eye–within cotton fabric. When exposed to light, the tiny metal particles, or nanostructures, released bursts of energy that degraded any organic matter on the fabric in as little as six minutes, said Rajesh Ramanathan, a postdoctoral fellow at RMIT University, in Melbourne.
The development, reported recently in the journal Advanced Materials Interfaces, represents an early stage of research into nano-enhanced fabrics that have the ability to clean themselves, Dr. Ramanathan said. The tiny metal particles don’t change the look or feel of the fabric. They also stay on the surface of the garment even when it is rinsed in water, meaning they can be used over and over on new grime, he said.

U.S. Science Agencies Omit Margin of Error in Warming Stats

(p. A13) The year 2016 was the warmest ever recorded–so claimed two U.S. agencies, NASA’s Goddard Institute for Space Studies and the Commerce Department’s National Oceanic and Atmospheric Administration. Except it wasn’t, according to the agencies’ own measures of statistical uncertainty.
Such fudge is of fairly recent vintage. Leaving any discussion of the uncertainty interval out of press releases only became the norm in the second year of the Obama administration. Back when he was presenting the 2008 numbers, NASA’s James Hansen, no slouch in raising climate alarms, nevertheless made a point of being quoted saying such annual rankings can be “misleading because the difference in temperature between one year and another is often less than the uncertainty in the global average.”
Statisticians wouldn’t go through the trouble of assigning an uncertainty value unless it meant something. Two measurements separated by less than the margin of error are the same. And yet NASA’s Goddard Institute, now under Mr. Hansen’s successor Gavin Schmidt, put out a release declaring 2014 the “warmest year in the modern record” when it was statistically indistinguishable from 2005 and 2010.
. . .
. . . other countries like the U.K. and Japan also do sophisticated monitoring and end up with findings roughly similar to the findings of U.S. agencies, yet they don’t feel the need to lie about it. For instance, the U.K. Met Office headlined its 2016 report “one of the warmest two years on record.” A reader only had to progress to the third paragraph to discover that the difference over 2015 was one-tenth the margin of error.

Two Die from Listeria in Artisanal Cheese

(p. A19) Two people have died following an outbreak of listeria linked to a popular artisanal raw milk cheese made in upstate New York, the authorities said this week.
The deaths occurred in Vermont and Connecticut, local officials said. Four other people in New York and Florida reported feeling sick after eating Ouleout, the artisanal cheese, which is produced by Vulto Creamery in Walton, N.Y.
. . .
Ouleout has been celebrated across the United States as much for its unusual back story as for its flavor: It was created by Jos Vulto, a Dutch artist linked to the Museum of Modern Art, who started making cheese in his apartment and aging it under a sidewalk in Brooklyn.
. . .
Mr. Vulto came to the United States from the Netherlands in 1990, according to several media outlets specializing in cheese. He spent two years as an artist-in-residence at P.S. 1 in Queens, a contemporary art institution affiliated with the Museum of Modern Art in New York. He specialized in crafting abstract installations made of metal.
His specialty involved “wrapping empty buildings in cloth and building contained fires of sawdust and hay inside,” according to Culture Cheese Mag. When the building started to emit smoke, the cloth absorbed an imprint of the building. Mr. Vulto called the technique “rooking,” a play on the Dutch word for smoke.
In 2008, Mr. Vulto switched to cheese making, reportedly inspired by the stink caused by a carton of soured milk in his refrigerator. He began creating rudimentary cheese in his apartment, and gradually mastered the art by making and remaking new batches and studying techniques.

British Government Environmentalists Increase London Air Pollution

(p. A4) London is choking from record levels of pollution, much of it caused by diesel cars and trucks, as well as wood-burning fires in private homes, a growing trend.
. . .
London’s air pollution today is different from seven decades ago, and more insidious. No longer thick as “pea soup,” as it was traditionally described, the city’s air is now laced with nitrogen dioxide — a toxic gas mostly produced by vehicles with diesel engines.
. . .
The current problem is, in part, an unintended consequence of previous efforts to aid the environment.
The British government provided financial incentives to encourage a shift to diesel engines because laboratory tests suggested that would cut harmful emissions and combat climate change. Yet, it turned out that diesel cars emit on average five times as much emissions in real-world driving conditions as in the tests, according to a British Department for Transport study.
“No one at the time thought of the consequences of increased nitrogen dioxide emissions from diesel, and the policy of incentivizing diesel was so successful that an awful lot of people bought diesel cars,” said Anna Heslop, a lawyer at ClientEarth, an environmental law firm that last year forced the British government to produce a better plan to improve air quality.
. . .
Bob Miller, 69, a cabdriver who has crisscrossed London for 30 years, wasn’t convinced. He has lost faith in recommendations by policy makers and experts, he said.
“We were told how wonderful diesel is, how they were supposed to be cleaner than petrol,” Mr. Miller said, idling his cab in heavy traffic with the window open.
“The experts make the rules, then they’re wrong,” he said, shaking his head. “I give up.”

U.S. Forest Service Killed “Prometheus,” World’s Oldest Tree

(p. D9) Great Basin’s . . . big draw–trees about as old as Egyptian hieroglyphics–sits at the top of the sky island in Wheeler Peak Bristlecone Grove.
. . .
At the grove, a stand of weather-battered bristlecone pines await, just as they have for between 3,000 and 4,000 years. With their knobby trunks and gnarled branches, the trees look like characters in an animated film’s enchanted forest, ready to burst into song. They often have only a small strip of bark, with the rest of the trunk bare, exposing the smooth, rich browns, yellows and grays in its fine grain.
At one time the oldest known tree in the world lived here. Its dignified appearance earned it the name Prometheus. In 1964, two decades before Great Basin became a national park, a researcher, trying to collect data about the area’s climate history, drilled into defenseless Prometheus (not knowing its exact age) to examine its rings. When his coring instrument got stuck, the Forest Service felled the tree to retrieve his tool– only to discover that the tree was 4,900 years old.
Oops.

Coastal Damage Caused by Storm Surges at High Tide, Not by Tiny Rise in Sea Levels

(p. A11) When Teddy Roosevelt built his Sagamore Hill on Long Island, he did so a quarter mile from shore at an elevation of 115 feet not because he disdained proximity to the beach or was precociously worried about climate change. The federal government did not stand ready with taxpayer money to defray his risk.
Estimates vary, but sea levels may have risen two millimeters a year over the past century. Meanwhile, tidal cycles along the U.S. east coast range from 11 feet every day (in Boston) to two feet (parts of Florida).
On top of this, a “notable surge event” can produce a storm surge of seven to 23 feet, according to a federal list of 10 hurricanes over the past 70 years.
We should not exaggerate the degree to which homeowners are being asked to shoulder their own risks. Washington is doling out five-figure checks to Jersey homeowners to raise houses on pilings to reduce the federal government’s future rebuilding costs. But, to state the obvious, normal tidal variation plus storm surge is the danger to coastal property. Background sea-level rise is a non-factor. A FEMA study from several years ago found that fully a quarter of coastal dwellings are liable to be destroyed over a 50-year period.
Though it pleased New York Gov. Andrew Cuomo to pretend Superstorm Sandy in 2012 was caused by global warming, the storm wasn’t even a hurricane by the time it hit shore–it just happened to hit at peak tide. Sure, certain people in Florida and elsewhere like to conflate the two. It’s in their interests to do so.
