Less-Ventilated Energy-Efficient Buildings Reduce Indoor Air Quality, Harming Cognitive Performance

(p. D6) A new study shows that poor indoor air quality is associated with subtle impairments in a number of cognitive functions, including our ability to concentrate and process information. The study tracked 302 office workers in commercial buildings in six countries — the United States, Britain, China, India, Mexico and Thailand — for 12 months.

The scientists used monitors to measure ventilation and indoor air quality in the buildings, including levels of fine particulate matter, which includes dust and minuscule particles from smoking, cleaning products and outdoor air pollution that seeps into the building. The workers were asked to use an app to take regular cognitive tests during the workday. The tests included simple math problems, as well as a tricky color and word brain teaser called the Stroop test, in which a word like “blue” or “purple” is printed in green or red ink.  . . .

The study found that the office workers in buildings with the poorest indoor air quality tended to perform worse on the brain teasers. While the effect wasn’t dramatic, the findings add to a growing body of evidence suggesting that the air we breathe affects brain health.

. . .

“This study looked at how several factors in the indoor environment have an immediate impact on our cognitive function and performance,” said Joseph G. Allen, the director of the Harvard Healthy Buildings program and the study’s senior author. “This study shows that the air you’re breathing at your desk at that moment has an impact on how well you think.”

In the past, air quality control in buildings has been mostly focused on energy efficiency and comfort, with little consideration given to infection control or overall worker health.

. . .

Dr. Allen is the co-author of a new book, “Healthy Buildings: How Indoor Spaces Drive Performance and Productivity.” He said he’s been encouraged to see more businesses and individuals taking indoor air quality more seriously as a result of the pandemic. Recently he saw a job posting at a major company advertising for a “head of healthy buildings” in the company’s global real estate division.

“It tells you that serious companies are changing how they approach their buildings, and they’re not thinking about this as a one-off during Covid,” said Dr. Allen.

. . .

“The pressure is coming from employees, parents of kids in school, teachers — there’s a heightened level of awareness and expertise,” said Dr. Allen. “How many people were talking about MERV 13 filters prior to the pandemic? This knowledge that our indoor spaces have been underperforming is not going away. I think people are rightly frustrated and fed up with it.”

Best New Climate Models Fail at Accurately “Hind-Casting” Past Temperatures

(p. A1) BOULDER, Colo.—For almost five years, an international consortium of scientists was chasing clouds, determined to solve a problem that bedeviled climate-change forecasts for a generation: How do these wisps of water vapor affect global warming?

They reworked 2.1 million lines of supercomputer code used to explore the future of climate change, adding more-intricate equations for clouds and hundreds of other improvements. They tested the equations, debugged them and tested again.

The scientists would find that even the best tools at hand can’t model climates with the sureness the world needs as rising temperatures impact almost every region.

When they ran the updated simulation in 2018, the conclusion jolted them: Earth’s atmosphere was much more sensitive to greenhouse gases than decades of previous models had predicted, and future temperatures could be much higher than feared—perhaps even beyond hope of practical remedy.

(p. A9) “We thought this was really strange,” said Gokhan Danabasoglu, chief scientist for the climate-model project at the Mesa Laboratory in Boulder at the National Center for Atmospheric Research, or NCAR.

. . .

As world leaders consider how to limit greenhouse gases, they depend heavily on what computer climate models predict. But as algorithms and the computer they run on become more powerful—able to crunch far more data and do better simulations—that very complexity has left climate scientists grappling with mismatches among competing computer models.

While vital to calculating ways to survive a warming world, climate models are hitting a wall. They are running up against the complexity of the physics involved; the limits of scientific computing; uncertainties around the nuances of climate behavior; and the challenge of keeping pace with rising levels of carbon dioxide, methane and other greenhouse gases. Despite significant improvements, the new models are still too imprecise to be taken at face value, which means climate-change projections still require judgment calls.

“We have a situation where the models are behaving strangely,” said Gavin Schmidt, director of the National Aeronautics and Space Administration’s Goddard Institute for Space Sciences, a leading center for climate modeling. “We have a conundrum.”

. . .

In its guidance to governments last year, the U.N. climate-change panel for the first time played down the most extreme forecasts.

Before making new climate predictions for policy makers, an independent group of scientists used a technique called “hind-casting,” testing how well the models reproduced changes that occurred during the 20th century and earlier. Only models that re-created past climate behavior accurately were deemed acceptable.

In the process, the NCAR-consortium scientists checked whether the advanced models could reproduce the climate during the last Ice Age, 21,000 years ago, when carbon-dioxide levels and temperatures were much lower than today. CESM2 and other new models projected temperatures much colder than the geologic evidence indicated. University of Michigan scientists then tested the new models against the climate 50 million years ago when greenhouse-gas levels and temperatures were much higher than today. The new models projected higher temperatures than evidence suggested.

When Humans Control Animals, Their Wily Resilience Can Cause “Unforeseen Consequences”

(p. A15) For the past three years, a gray squirrel has set out to ruin my life, chewing leaves off my beloved exotic hibiscus and geraniums.

. . .

. . . , Mary Roach’s “Fuzz: When Nature Breaks the Law” makes me feel grateful that my nemesis is only a rodent, and that I live in Ohio, not Colorado or India. My refrigerator will not be emptied by a bear; I will not be throttled by a leopard while taking out the compost.

. . .

There’s something demonic at work in India’s leopards and macaques, but the dilemma finds its root in human behavior. For centuries, feeding monkeys has been considered a religious offering, but this ritual has fueled a certain conviction on the monkeys’ part that humans are in service to them. Ms. Roach’s attempts to pin down government officials on how they might tackle the problem (including hiring more monkey catchers and staffing more monkey sterilization centers) are hilariously convoluted and laced with bizarre anecdotes. She’s passed from one office to the next and back again, never getting an answer. Before redirecting her, one official “veered off into a story about a macaque that got inside the All India Institute of Medical Sciences and took to pulling IV needles out of patients’ arms and sucking the glucose like a child with a straw in a pop bottle.”

During World War II, the U.S. military established a naval air station on Midway Atoll, the strategically significant string of islets halfway between North America and Asia. But the islands turned out to be also a significant nesting ground for thousands of albatrosses, and the result was hundreds of collisions between the airplanes and the huge soaring birds. It is heartbreaking to read of sailors being made to club the long-living albatrosses—80,000 in one assault, 21,000 in another—to reduce the population. Still, nature prevailed. “For a brief time the hazard to aircraft was reduced,” read one report. “The following season there appeared to be as many albatrosses as before.” After every possible deterrent and lethal attack on the gentle birds failed, the air base was closed and in 1993 converted into a refuge. The contrast between this midcentury horror and the reverence shown earlier this year for Wisdom, the 70-year-old Laysan albatross still nesting on Midway, could hardly be more stark.

. . .

This book is largely about the unspooling of unforeseen consequences, and our feeble attempts to put the animal genies we’ve freed back into their bottles.

“Hell No,” Greta Thunberg’s Dad Would Not Go to Global Warming COP26 Summit

(p. A1) One person is delighted not to attend the United Nations climate change conference this month.

Greta Thunberg’s dad.

For three years, Svante Thunberg chaperoned his daughter to events across the globe, including spending weeks cooped up in a sailboat crossing the Atlantic, as Greta Thunberg rose to become the leading face of youth climate activism.

Now Ms. Thunberg, who turned 18 in January, is an adult and Mr. Thunberg, 52, can finally get a bit of his life back.

“Hell no,” says Mr. Thunberg (p. A10) when asked if he will be traveling to the COP26 summit, currently underway in Glasgow. “I am certainly not going.”

. . .

Mr. Thunberg, who runs a music-production business and once aspired to owning an SUV, went along with his daughter to attend two previous COP summits. He now drives an electric car. Her parents had to set up a foundation to manage over a million dollars of prize money their child won and wants to give away. Mr. Thunberg says he quit the foundation’s board as soon as he could.

“We have other things to do,” he says. Ms. Thunberg’s mother, Ms. Ernman, is an opera singer who once represented Sweden at the Eurovision song contest. “We have jobs,” Mr. Thunberg says.

. . .

The parental odyssey started after Greta, aged about eight, watched a TV program about trash clogging the oceans. Ms. Thunberg was shocked that more wasn’t being done to address this, her father says.

She went into a depression at age 11. She largely stopped talking, virtually stopped eating for several months and had to be taken out of school. She says she was later diagnosed with Asperger syndrome and obsessive-compulsive disorder. Ms. Thunberg, her parents and her younger sister chronicled this in a book called “Our House Is On Fire.”

. . .

. . . climate activism appeared to energize their daughter, who was now eating better and proving very adept at delivering blunt messages in public.

Her parents were amazed that, despite not saying anything particularly new on climate change, she was cutting through. Global dignitaries lined up to invite her to lecture them on their failure to act.

Asteroids as Another Existential Threat

Do we best prepare for uncertain existential future threats by huge centrally planned government spending, or by allowing the flourishing of general purpose technologies and nimble entrepreneurs?

(p. C4) The most immediate threat isn’t from the largest or smallest asteroids but from those in between. Over the past two decades, asteroid hunters with NASA and other international space agencies have identified and tracked the orbits of more than 20,000 asteroids—also known as near-Earth objects—that pass through our neighborhood as they orbit the sun. Of those, about 2,000 are classified as potentially hazardous—asteroids that are large enough (greater than 150 yards in diameter) to cause local destruction and that come close enough to Earth to someday pose a threat.

The good news is that scientists don’t expect any of these known asteroids to collide with Earth within at least the next century. Some will come pretty close, though: On an unlucky Friday the 13th in April 2029, the thousand-foot-wide asteroid Apophis will pass a mere 19,000 miles from Earth—closer than the satellites that bring us DISH TV.

But here’s the bad news: Hundreds of thousands of other near-Earth asteroids, both large and small, haven’t been identified. We have no idea where they are and where they are going. On Feb. 15, 2013, a relatively small, 60-foot-wide asteroid traveling at 43,000 mph exploded in the atmosphere near the Russian city of Chelyabinsk, sending out a blast wave that injured 1,500 people. No one had seen the asteroid coming.

We need to find and track these unknown invaders as soon as possible. But while NASA’s “planetary defense” budget has been steadily increasing over the past decade, the $150 million allocated in 2019 for asteroid detection, asteroid tracking and related programs amounts to less than 1% of the space agency’s $21.5 billion budget.

Feds Impede Consumer Choice by Going Back to Incandescent Ban

(p. A16) In 2019, the Trump administration blocked a rule designed to phase out older incandescent bulbs, calling it unnecessary and an impediment to consumer choice.

With the move, the administration heeded to both industry demands as well as free market proponents who have long railed against tougher efficiency regulations for consumer appliances and goods, like energy-saving bulbs or water-saving dishwashers, as governmental overreach.

“The new bulb is many times more expensive, and I hate to say it, it doesn’t make you look as good,” Donald J. Trump, the former president, quipped at a White House meeting in 2019, referring to an early common complaint that LEDs emit a harsher light, though recent LED lights come in warmer hues. “We’re bringing back the old light bulb,” he later told a rally in Michigan.

The Biden administration has moved to reinstate the standards. But in a letter to the Department of Energy last year, NEMA, the industry group, urged federal rules to allow companies to manufacture and import inefficient bulbs for at least another year, followed by another year or more to sell out stockpiled inventory.

“Unprecedented” and “Huge” Serendipitous Discovery of 60 Million Icefish Nests

(p. D3) As soon as the remotely operated camera glimpsed the bottom of the Weddell Sea, more than a thousand feet below the icy ceiling at the surface, Lilian Boehringer, a student researcher at the Alfred Wegener Institute in Germany, saw the icefish nests. The sandy craters dimpled the seafloor, each the size of a hula hoop and less than a foot apart. Each crater held a single, stolid icefish, dark pectoral fins outspread like bat wings over a clutch of eggs.

Aptly named icefishes thrive in waters just above freezing with enormous hearts and blood that runs clear as vodka. . . .

The sighting occurred in February 2021 in the camera room aboard a research ship, the Polarstern, which had come to the Weddell Sea to study other things, not icefish. It was 3 a.m. near Antarctica, meaning the sun was out but most of the ship was asleep. To Ms. Boehringer’s surprise, the camera kept transmitting pictures as it moved with the ship, revealing an uninterrupted horizon of icefish nests every 20 seconds.

. . .

The nests persisted for the entire four-hour dive, with a total of 16,160 recorded on camera. After two more dives by the camera, the scientists estimated the colony of Neopagetopsis ionah icefish stretched across 92 square miles of the serene Antarctic sea, totaling 60 million active nests. The researchers described the site — the largest fish breeding colony ever discovered — in a paper published Thursday in the journal Current Biology.

“Holy cow,” said C.-H. Christina Cheng, an evolutionary biologist at the University of Illinois-Urbana-Champaign, who was not involved with the research. “This is really unprecedented,” she said. “It is crazy dense. It is a major discovery.”

. . .

“The seafloor is not just barren and boring,” Dr. Purser said. “Such huge discoveries are still there to be made, even today in the 21st century.”

Economic Growth Reduces the Harms from Global Warming

(p. C3) Long-term economic growth is associated with both rising per capita energy consumption and slower population growth. For this reason, as the world continues to get richer, higher per capita energy consumption is likely to be offset by a lower population.

A richer world will also likely be more technologically advanced, which means that energy consumption should be less carbon-intensive than it would be in a poorer, less technologically advanced future. In fact, a number of the high-emissions scenarios produced by the United Nations Intergovernmental Panel on Climate Change involve futures in which the world is relatively poor and populous and less technologically advanced.

Affluent, developed societies are also much better equipped to respond to climate extremes and natural disasters. That’s why natural disasters kill and displace many more people in poor societies than in rich ones. It’s not just seawalls and flood channels that make us resilient; it’s air conditioning and refrigeration, modern transportation and communications networks, early warning systems, first responders and public health bureaucracies.

New research published in the journal Global Environmental Change finds that global economic growth over the last decade has reduced climate mortality by a factor of five, with the greatest benefits documented in the poorest nations. In low-lying Bangladesh, 300,000 people died in Cyclone Bhola in 1970, when 80% of the population lived in extreme poverty. In 2019, with less than 20% of the population living in extreme poverty, Cyclone Fani killed just five people.

Poor nations are most vulnerable to a changing climate. The fastest way to reduce that vulnerability is through economic development.

So while it is true that poor nations are most vulnerable to a changing climate, it is also true that the fastest way to reduce that vulnerability is through economic development, which requires infrastructure and industrialization. Those activities, in turn, require cement, steel, process heat and chemical inputs, all of which are impossible to produce today without fossil fuels.

“Fission Is in Fashion” and Is Over-Regulated

(p. A15) Fission is in fashion as drawbacks of intermittent wind and solar power emerge.

. . .

Regulatory limits on annual exposure around nuclear plants are less than a year’s background radiation from rocks and cosmic rays. Radiation scientists now know that people can safely absorb that much radiation every day because DNA is repaired and cells are replaced constantly in living beings. Yet regulators’ mandated limits, at a thousandth of what’s really harmful, create fright of all radiation. No one needed to be evacuated at Fukushima or around Chernobyl, places where thousands died from unwarranted fear and relocation stress.

DeSantis Upgrades Infrastructure to Mitigate Flooding

(p. A5) The Republican governor, unlike many of his Democratic counterparts, didn’t use the term “climate change” or endorse specific policies aimed at combating factors that most climate scientists say are driving warming, such as greenhouse-gas emissions. He focused on responding to the effects of a warming climate.

“What I’ve found is people, when they start talking about things like global warming, they typically use that as a pretext to do a bunch of left-wing things,” said Mr. DeSantis at the event. “We’re not doing any left-wing stuff.”

Governors and lawmakers in several Republican-led states, including Idaho, South Carolina and Texas, are taking a similar approach as concern about climate change increases. After natural disasters that research suggests are becoming more frequent and intense, they are taking measures such as infrastructure upgrades to mitigate flooding, wildfires and severe storms. Such moves are vital to their states’ economic livelihood, they say.

. . .

At the Oldsmar event, Mr. DeSantis outlined a proposal to dedicate more than $270 million to 76 projects aimed at bolstering defenses against rising sea levels and flooding. “We’re a low-lying state, we’re a storm-prone state, and we’re a flood-prone state,” he said.

Socialist Mayor’s Environmental Bicycles Turn Paris Streets into Risky Chaos

(p. 4) PARIS — On a recent afternoon, the Rue de Rivoli looked like this: Cyclists blowing through red lights in two directions. Delivery bike riders fixating on their cellphones. Electric scooters careening across lanes. Jaywalkers and nervous pedestrians scrambling as if in a video game.

Sarah Famery, a 20-year resident of the Marais neighborhood, braced for the tumult. She looked left, then right, then left and right again before venturing into a crosswalk, only to break into a rant-laden sprint as two cyclists came within inches of grazing her.

“It’s chaos!” exclaimed Ms. Famery, shaking a fist at the swarm of bikes that have displaced cars on the Rue de Rivoli ever since it was remade into a multilane highway for cyclists last year. “Politicians want to make Paris a cycling city, but no one is following any rules,” she said. “It’s becoming risky just to cross the street!”

The mayhem on Rue de Rivoli — a major traffic artery stretching from the Bastille past the Louvre to the Place de la Concorde — is playing out on streets across Paris as the authorities pursue an ambitious goal of making the city a European cycling capital by 2024.

Mayor Anne Hidalgo, who is campaigning for the French presidency, has been burnishing her credentials as an ecologically minded Socialist candidate. She has earned admirers and enemies alike with a bold program to transform greater Paris into the world’s leading environmentally sustainable metropolis, reclaiming vast swaths of the city from cars for parks, pedestrians and a Copenhagen-style cycling revolution.
