Islington’s project is just one of many innovations by cities around the world to provide heat to residents and businesses while reducing greenhouse gas emissions, improving efficiency and saving people money.

Stockholm is also using heat from sewage, as well as tapping data centers and other sources to supply heat for much of the city.

If you can start to use a whole array of waste heat streams, you’re taking out a big chunk of greenhouse gas emissions,

We don’t really need to burn gas at 1,000 degrees centigrade [1,832 degrees Fahrenheit] to get your bath to 30 degrees centigrade,” Dr. Gluyas added. “What we need to do is work with nature to optimize the use of heat.

The concept of district heating networks is not new and may, in fact, date from 14th-century France or even, some say, the Roman Empire

New York City has one of the world’s largest district systems to provide heat, cooling and, in some cases, even electricity to many buildings in Manhattan.

Though perhaps less wasteful than having a boiler in every single building, it is not the most efficient district heating system, as it was designed to heat a building on the coldest day of the year with all the windows open — partly a public health legacy of the 1918 pandemic.

But the innovation — which took more than five years to plan and build, and began operations in March 2020 — was to feed in heat from the Underground.

Typically, the hot air from the Underground is released into the air through stations and ventilation shafts. In this case, however, air is drawn from a ventilation shaft at an abandoned Underground station into an energy center where a series of heat transfers take place, eventually leading to delivery of the heat into the buildings in the network.

For our residents, locally, this is absolutely the right thing to do,” because it saves money in an area where many residents struggle to afford heat, Mr. Townsend said. “And this is a perfect solution for big cities across the world.

Heat from wastewater and sewage now provides about 70 percent of the space heating and hot water for the 43 buildings connected to the network, with the remaining 30 percent coming from natural gas, though the goal is to end that by 2030. The electricity powering the heat pumps is 97 percent zero-carbon, supplied by hydroelectric dams.

Every time we take a shower, do the dishes or do a load of laundry, the water is still hot when it goes down the drain,” said Ashley St. Clair, Vancouver’s senior renewable energy planner.“It’s flowing under our streets, and we’re already collecting it through the traditional infrastructure of wastewater pipes, and to be able to tap into that waste heat is really the ultimate circular economy.”

And it cannot come soon enough: This year alone, Vancouver has experienced several bouts of extreme weather, made more likely and intense because of climate change: heat domes, wildfires and catastrophic flooding, which recently cut the city off by road and rail from the rest of Canada. Having its own heat and hot water supply has been an additional benefit of the project, Ms. St. Clair said.

Stockholm, Mr. Rylander said, has particularly good connectivity to Northern Europe, Finland and Russia, which makes it attractive to data center companies, as does Sweden’s relatively clean power mix. However, they use biomass to produce a significant amount of heat and power, the renewable classification of which is debated by experts.

“If you establish a data center in a cold place like Sweden, it’s stupid to waste the heat, because heat has power and value in a cold country.”

“We’re very clear that we are an experiment, and we are doing the work that will enable others to benefit from it.”

the Great Resignation, it turns out, is largely an American phenomenon. European nations have been much more successful than we have at getting people back to work. In France, in particular, employment and labor force participation are now well above prepandemic levels. What explains this difference?

Europe, on the other hand, mainly relied on job retention schemes — government aid intended to keep people on employer payrolls even if they weren’t working at the moment.

where European labor support helped keep workers linked to their old jobs, facilitating a rapid return, U.S. policy allowed many of those links to be severed, making an employment recovery harder.

Perhaps one reason Europeans aren’t engaging in an American-style Great Resignation is that they don’t hate their jobs quite as much.

a significant number may have realized that low-paying jobs with lousy working conditions weren’t worth having

some jobs that are grueling and poorly paid here are less awful on the other side of the Atlantic. Famously, in Denmark McDonald’s pays more than $20 an hour and offers six weeks of paid vacation each year

the U.S. does stand out among wealthy countries for having a low minimum wage, for offering very little vacation time and for failing to offer parental and sick leave

In Russia in March, the four most-downloaded apps for both MacOS and Android were VPNs.

But the fifth most in-demand app was the encrypted messenger Telegram, probably the best available source of uncensored news about the war. I, for one, am using Telegram to access news from a wealth of Russian and Ukrainian sources. 

According to a poll taken in March, TV is the main source of information for 50% of Russians, and 45% trust it. But then that’s just what people living under an autocratic regime tell pollsters — not necessarily what they actually think.

even if the poll data reflect reality, there is a large age gap in TV viewing: Younger people watch little TV, and more than a quarter of adult Russians don’t watch it at all, instead relying on the internet for news. They are the ones who use VPNs to access independent news sources and subscribe to unfiltered Telegram channels. They also know that Google is a better search engine than Yandex.

Even Putin’s press secretary, Dmitry Peskov, openly admits using a VPN to access the banned Western social networks: The official policy is that such use is not punishable. And indeed there have been no reprisals so far for using Facebook or Instagram, both declared “extremist” organizations. It’s extremely difficult for the secret police to track such use on a grand scale while VPNs remain legal.

And even if one assumes that a TV-only audience of older, technology-shy people really exists, it cannot be isolated from direct communication with other people whose horizons aren’t as limited.

older Russians are extremely cautious on the phone (and now also on Skype, WhatsApp, Telegram or any other means of remote communication). They will not endanger themselves by blabbing heresy — too many people suffered for it in the Soviet Union, a country that modern Russia increasingly resembles.

The surviving Soviets may not have their children’s technology smarts, but they beat them hands down in the kind of street smarts required for survival in a police state. They also have plenty of experience reading between propaganda lines. The assumption that these people, who laughed privately at the Soviet ideological fodder, have suddenly lost their ability to take state discourse with a bucketful of salt, seems less plausible to me than the idea that they’re reverting to oyster mode as their familiar environment returns.

Ordinary Germans did know what the Nazis were up to, research has shown. Even with that era’s relatively limited media and communications, the Nazis’ crimes were impossible to miss, no matter how one might have tried. They could, however, refuse to fess up to their knowledge; they could even convince themselves of their own ignorance. 

That, too, takes quite an effort, I realize as I read some fellow Russians’ social network posts or listen to Moscow acquaintances say things like “Not everything is black and white” or “We will never know the whole truth.” I have a sense that, if I press them, some might burst into tears or lash out at me in anger. The strain is ever-present, and I’m not sure whether it’s rooted in fear or an instinct for self-preservation: My own family struggles to cope with knowing that the Russian atrocities are being committed in our name, too.

It’s a burden we have to bear — probably for the rest of our lives. Those who will insist they’d been fooled by propaganda won’t be free of it. In these brutal weeks, only the openly, actively complicit are able to avoid the weight that’s bending Russians to the ground. 

With respect to crime, poverty and homelessness, Brown argued,One thing that may occur is that disinvestment in city downtowns will alter the spatial distribution of these elements in cities — i.e. in which neighborhoods or areas of a city is crime more likely, and homelessness more visible. Urban downtowns are often policed such that these visible elements of poverty are pushed to other parts of the city where they will not interfere with commercial activities. But absent these activities, there may be less political pressure to maintain these areas. This is not to say that the overall crime rate or homelessness levels will necessarily increase, but their spatial redistribution may further alter the trajectory of commercial downtowns — and the perception of city crime in the broader public.

“The more dramatic effects on urban geography,” Brown continued,may be how this changes cities in terms of economic and racial segregation. One urban trend from the last couple of decades is young white middle- and upper-class people living in cities at higher rates than previous generations. But if these groups become less likely to live in cities, leaving a poorer, more disproportionately minority population, this will make metropolitan regions more polarized by race/class.

the damage that even the perception of rising crime can inflict on Democrats in a Nov. 27 article, “Meet the Voters Who Fueled New York’s Seismic Tilt Toward the G.O.P.”: “From Long Island to the Lower Hudson Valley, Republicans running predominantly on crime swept five of six suburban congressional seats, including three that President Biden won handily that encompass some of the nation’s most affluent, well-educated commuter towns.

In big cities like New York and San Francisco we estimate large drops in retail spending because office workers are now coming into city centers typically 2.5 rather than 5 days a week. This is reducing business activity by billions of dollars — less lunches, drinks, dinners and shopping by office workers. This will reduce city hall tax revenues.

Public transit systems are facing massive permanent shortfalls as the surge in working from home cuts their revenues but has little impact on costs (as subway systems are mostly a fixed cost. This is leading to a permanent 30 percent drop in transit revenues on the New York Subway, San Francisco Bart, etc.

These difficulties for cities will not go away anytime soon. Bloom provided data showing strong economic incentives for both corporations and their employees to continue the work-from-home revolution if their jobs allow it:

First, “Saved commute time working from home averages about 70 minutes a day, of which about 40 percent (30 minutes) goes into extra work.” Second, “Research finds hybrid working from home increases average productivity around 5 percent and this is growing.” And third, “Employees also really value hybrid working from home, at about the same as an 8 percent pay increase on average.

three other experts in real estate economics, Arpit Gupta, of N.Y.U.’s Stern School of Business, Vrinda Mittal, both of the Columbia Business School, and Van Nieuwerburgh. They anticipate disaster in their September 2022 paper, “Work From Home and the Office Real Estate Apocalypse.”

“Our research,” Gupta wrote by email,emphasizes the possibility of an ‘urban doom loop’ by which decline of work in the center business district results in less foot traffic and consumption, which adversely affects the urban core in a variety of ways (less eyes on the street, so more crime; less consumption; less commuting) thereby lowering municipal revenues, and also making it more challenging to provide public goods and services absent tax increases. These challenges will predominantly hit blue cities in the coming years.

the three authors “revalue the stock of New York City commercial office buildings taking into account pandemic-induced cash flow and discount rate effects. We find a 45 percent decline in office values in 2020 and 39 percent in the longer run, the latter representing a $453 billion value destruction.”

Extrapolating to all properties in the United States, Gupta, Mittal and Van Nieuwerburgh write, the “total decline in commercial office valuation might be around $518.71 billion in the short-run and $453.64 billion in the long-run.”

the share of real estate taxes in N.Y.C.’s budget was 53 percent in 2020, 24 percent of which comes from office and retail property taxes. Given budget balance requirements, the fiscal hole left by declining central business district office and retail tax revenues would need to be plugged by raising tax rates or cutting government spending.

Since March 2020, Manhattan has lost 200,000 households, the most of any county in the U.S. Brooklyn (-88,000) and Queens (-51,000) also appear in the bottom 10. The cities of Chicago (-75,000), San Francisco (-67,000), Los Angeles (-64,000 for the city and -136,000 for the county), Washington DC (-33,000), Seattle (-31,500), Houston (-31,000), and Boston (-25,000) make up the rest of the bottom 10.

Prior to the pandemic, these ecosystems were designed to function based on huge surges in their daytime population from commuters and tourists. The shock of the sudden loss of a big chunk of this population caused a big disruption in the ecosystem.

Just as the pandemic has caused a surge in telework, Loh wrote, “it also caused a huge surge in unsheltered homelessness because of existing flaws in America’s housing system, the end of federally-funded relief measures, a mental health care crisis, and the failure of policies of isolation and confinement to solve the pre-existing homelessness crisis.”

The upshot, Loh continued,is that both the visibility and ratio of people in crisis relative to those engaged in commerce (whether working or shopping) has changed in a lot of U.S. downtowns, which has a big impact on how being downtown ‘feels’ and thus perceptions of downtown.

The nation, Glaeser continued, isat an unusual confluence of trends which poses dangers for cities similar to those experienced in the 1970s. Event#1 is the rise of Zoom, which makes relocation easier even if it doesn’t mean that face-to-face is going away. Event#2 is a hunger to deal with past injustices, including police brutality, mass incarceration, high housing costs and limited upward mobility for the children of the poor.

Progressive mayors, according to Glaeser,have a natural hunger to deal with these problems at the local level, but if they try to right injustices by imposing costs on businesses and the rich, then those taxpayers will just leave. I certainly remember New York and Detroit in the 1960s and 1970s, where the dreams of progressive mayors like John Lindsay and Jerome Patrick Cavanagh ran into fiscal realities.

Richard Florida, a professor of economic analysis and policy at the University of Toronto, stands out as one of the most resolutely optimistic urban scholars. In his August 2022 Bloomberg column, “Why Downtown Won’t Die,”

His answer:

Great downtowns are not reducible to offices. Even if the office were to go the way of the horse-drawn carriage, the neighborhoods we refer to today as downtowns would endure. Downtowns and the cities they anchor are the most adaptive and resilient of human creations; they have survived far worse. Continual works in progress, they have been rebuilt and remade in the aftermaths of all manner of crises and catastrophes — epidemics and plagues; great fires, floods and natural disasters; wars and terrorist attacks. They’ve also adapted to great economic transformations like deindustrialization a half century ago.

Florida wrote that many urban central business districts are “relics of the past, the last gasp of the industrial age organization of knowledge work the veritable packing and stacking of knowledge workers in giant office towers, made obsolete and unnecessary by new technologies.”

“Downtowns are evolving away from centers for work to actual neighborhoods. Jane Jacobs titled her seminal 1957 essay, which led in fact to ‘The Death and Life of Great American Cities,’ ‘Downtown Is for People’ — sounds about right to me.”

Despite his optimism, Florida acknowledged in his email thatAmerican cities are uniquely vulnerable to social disorder — a consequence of our policies toward guns and lack of a social safety net. Compounding this is our longstanding educational dilemma, where urban schools generally lack the quality of suburban schools. American cities are simply much less family-friendly than cities in most other parts of the advanced world. So when people have kids they are more or less forced to move out of America’s cities.

What worries me in all of this, in addition to the impact on cities, is the impact on the American economy — on innovation. and competitiveness. Our great cities are home to the great clusters of talent and innovation that power our economy. Remote work has many advantages and even leads to improvements in some kinds of knowledge work productivity. But America’s huge lead in innovation, finances, entertainment and culture industries comes largely from its great cities. Innovation and advance in. these industries come from the clustering of talent, ideas and knowledge. If that gives out, I worry about our longer-run economic future and living standards.

The risk that comes with fiscal distress is clear: If city governments face budget shortfalls and begin to cut back on funding for public transit, policing, and street outreach, for the maintenance of parks, playgrounds, community centers, and schools, and for services for homelessness, addiction, and mental illness, then conditions in central cities will begin to deteriorate.

There is reason for both apprehension and hope. Cities across time have proven remarkably resilient and have survived infectious diseases from bubonic plague to cholera to smallpox to polio. The world population, which stands today at eight billion people, is 57 percent urban, and because of the productivity, innovation and inventiveness that stems from the creativity of human beings in groups, the urbanization process is quite likely to continue into the foreseeable future. There appears to be no alternative, so we will have to make it work.

I had other doubts, too. It seemed hubristic, or worse, to make multitrillion-dollar policy bets based on computer models trying to forecast climate patterns decades into the future. Climate activists kept promoting policies based on technologies that were either far from mature (solar energy) or sometimes actively harmful (biofuels).

Expensive efforts to curb greenhouse gas emissions in Europe and North America seemed particularly fruitless when China, India and other developing countries weren’t about to curb their own appetite for fossil fuels

just how fast is Greenland’s ice melting right now? Is this an emergency for our time, or is it a problem for the future?

His pitch was simple: The coastline we have taken for granted for thousands of years of human history changed rapidly in the past on account of natural forces — and would soon be changing rapidly and disastrously by man-made ones. A trip to Greenland, which holds one-eighth of the world’s ice on land (most of the rest is in Antarctica) would show me just how drastic those changes have been. Would I join him?

Greenland is about the size of Alaska and California combined and, except at its coasts, is covered by ice that in places is nearly two miles thick. Even that’s only a fraction of the ice in Antarctica, which is more than six times as large

Greenland’s ice also poses a nearer-term risk because it is melting faster. If all its ice were to melt, global sea levels would rise by some 24 feet. That would be more than enough to inundate hundreds of coastal cities in scores of nations, from Jakarta and Bangkok to Copenhagen and Amsterdam to Miami and New Orleans.

There was also a millenarian fervor that bothered me about climate activism, with its apocalyptic imagery (the Statue of Liberty underwater) and threats of doom unless we were willing to live far more frugally.

“We haven’t had a good positive mass balance year since the late 1990s,” he told me in a follow-on email when I asked him to explain the data for me. The losses can vary sharply by year. The annualized average over the past 30 years, he added, is 170 gigatons per year. That’s the equivalent of about 5,400 tons of ice loss per second. That “suggests that Greenland ice loss has been tracking the I.P.P.C. worse-case, highest-carbon-emission scenario.

The data shows unmistakably that Greenland’s ice is not in balance. It is losing far more than it is gaining.

scientists have been drilling ice-core samples from Greenland for decades, giving them a very good idea of climatic changes stretching back thousands of years. Better yet, a pair of satellites that detect anomalies in Earth’s gravity fields have been taking measurements of the sheet regularly for nearly 20 years, giving scientists a much more precise idea of what is happening.

it’s hard to forecast with any precision what that means. “Anyone who says they know what the sea level is going to be in 2100 is giving you an educated guess,” said NASA’s Willis. “The fact is, we’re seeing these big ice sheets melt for the first time in history, and we don’t really know how fast they can go.”

His own educated guess: “By 2100, we are probably looking at more than a foot or two and hopefully less than seven or eight feet. But we are struggling to figure out just how fast the ice sheets can melt. So the upper end of range is still not well known.”

On the face of it, that sounds manageable. Even if sea levels rise by eight feet, won’t the world have nearly 80 years to come to grips with the problem, during which technologies that help us mitigate the effects of climate change while adapting to its consequences are likely to make dramatic advances?

Won’t the world — including countries that today are poor — become far richer and thus more capable of weathering the floods, surges and superstorms?

The average rate at which sea level is rising around the world, he estimates, has more than tripled over the past three decades, to five millimeters a year from 1.5 millimeters. That may still seem minute, yet as the world learned during the pandemic, exponential increases have a way of hitting hard.

“When something is on a straight line or a smooth curve, you can plot its trajectory,” Englander said. “But sea level, like earthquakes and mudslides, is something that happens irregularly and can change rather quickly and surprise us. The point is, you can no longer predict the future by the recent past.”

In The Wall Street Journal’s editorial pages, where I used to work, the theoretical physicist Steven Koonin, a former under secretary for science in the Obama administration’s Energy Department, cast doubt on the threat from Thwaites in a voice that could have once been mine. He also thinks the risks associated with Greenland’s melting are less a product of human-induced global warming than of natural cycles in North Atlantic currents and temperatures, which over time have a way of regressing to the mean.

Even the poorest countries, while still unacceptably vulnerable, are suffering far fewer human and economic losses to climate-related disasters.

Another climate nonalarmist is Roger Pielke Jr., a professor of environmental studies at the University of Colorado Boulder. I call Pielke a nonalarmist rather than a skeptic because he readily acknowledges that the challenges associated with climate change, including sea-level rise, are real, serious and probably unstoppable, at least for many decades.

“If we have to have a problem,” he told me when I reached him by phone, “we probably want one with a slow onset that we can see coming. It’s not like an asteroid coming from space.”

“Since the 1940s, the impact of floods as a proportion of U.S. gross domestic product has dropped by 70 percent-plus,” Pielke said. “We see this around the world, across phenomena. The story is that fewer people are dying and we are having less damage proportional to G.D.P.”

“Much climate reporting today highlights short-term changes when they fit the narrative of a broken climate but then ignores or plays down changes when they don’t, often dismissing them as ‘just weather,’” he wrote in February.

Global warming is real and getting worse, Pielke said, yet still it’s possible that humanity will be able to adapt to, and compensate for, its effects.

A few years ago, I would have found voices like Koonin’s and Pielke’s persuasive. Now I’m less sure. What intervened was a pandemic.

That’s what I thought until the spring of 2020, when, along with everyone else, I experienced how swiftly and implacably nature can overwhelm even the richest and most technologically advanced societies. It was a lesson in the sort of intellectual humility I recommended for others

It was also a lesson in thinking about risk, especially those in the category known as high-impact, low-probability events that seem to be hitting us with such regularity in this century: the attacks of Sept. 11, 2001; the tsunamis of 2004 and 2011, the mass upheavals in the Arab world

What if the past does nothing to predict the future? What if climate risks do not evolve gradually and relatively predictably but instead suddenly soar uncontrollably? How much lead time is required to deal with something like sea-level rise? How do we weigh the risks of underreacting to climate change against the risks of overreacting to it?

I called Seth Klarman, one of the world’s most successful hedge-fund managers, to think through questions of risk. While he’s not an expert on climate change, he has spent decades thinking deeply about every manner of risk

And we will almost certainly have to do it from sources other than Russia, China, the Democratic Republic of Congo and other places that pose unacceptable strategic, environmental or humanitarian risks

“If you face something that is potentially existential,” he explained, “existential for nations, even for life as we know it, even if you thought the risk is, say, 5 percent, you’d want to hedge against it.”

“One thing we try to do,” he said, “is we buy protection when it’s really inexpensive, even when we think we may well not need it.” The forces contributing to climate change, he noted, echoing Englander, “might be irreversible sooner than the damage from climate change has become fully apparent. You can’t say it’s far off and wait when, if you had acted sooner, you might have dealt with it better and at less cost. We have to act now.”

In other words, an ounce of prevention is worth a pound of cure. That’s particularly true if climate change is akin to cancer — manageable or curable in its earlier stages, disastrous in its later ones.

As I’ve always believed, knowing there is grave risk to future generations — and expecting current ones to make immediate sacrifices for it — defies most of what we know about human nature. So I began to think more deeply about that challenge, and others.

For the world to achieve the net-zero goal for carbon dioxide emissions by 2050, according to the International Energy Agency, we will have to mine, by 2040, six times the current amounts of critical minerals — nickel, cobalt, copper, lithium, manganese, graphite, chromium, rare earths and other minerals and elements — needed for electric vehicles, wind turbines and solar panels.

The poster child for this kind of magical thinking is Germany, which undertook a historic Energiewende — “energy revolution” — only to come up short. At the turn of the century, Germany got about 85 percent of its primary energy from fossil fuels. Now it gets about 78 percent, a puny reduction, considering that the country has spent massive sums on renewables to increase the share of electricity it generates from them.

As in everything else in life, so too with the environment: There is no such thing as a free lunch. Whether it’s nuclear, biofuels, natural gas, hydroelectric or, yes, wind and solar, there will always be serious environmental downsides to any form of energy when used on a massive scale. A single industrial-size wind turbine, for instance, typically requires about a ton of rare earth metals as well as three metric tons of copper, which is notoriously destructive and dirty to mine.

no “clean energy” solution will easily liberate us from our overwhelming and, for now, inescapable dependence on fossil fuels.

Nobody brings the point home better than Vaclav Smil, the Canadian polymath whose most recent book, “How the World Really Works,” should be required reading for policymakers and anyone else interested in a serious discussion about potential climate solutions.

“I’ve talked to so many experts and seen so much evidence,” he told me over Zoom, “I’m convinced the climate is changing, and addressing climate change has become a philanthropic priority of mine.”

Things could turn a corner once scientists finally figure out a technical solution to the energy storage problem. Or when governments and local actors get over their NIMBYism when it comes to permitting and building a large energy grid to move electricity from Germany’s windy north to its energy-hungry south. Or when thoughtful environmental activists finally come to grips with the necessity of nuclear energy

Till then, even as I’ve come to accept the danger we face, I think it’s worth extending the cancer metaphor a little further: Just as cancer treatments, when they work at all, can have terrible side effects, much the same can be said of climate treatments: The gap between an accurate diagnosis and effective treatment remains dismayingly wide

Only when countries like Vietnam and China turned to a different model, of largely bottom-up, market-driven development, did hundreds of millions of people get lifted out of destitution.

the most important transformation has come in agriculture, which uses about 70 percent of the world’s freshwater supply.

Farmers gradually adopted sprinkler and drip irrigation systems, rather than more wasteful flood irrigation, not to conserve water but because the technology provided higher crop yields and larger profit margins.

Water shortages “will spur a revolutionary, aggressive approach to getting rid of flood irrigation,” said Seth Siegel, the chief sustainability officer of the Israeli AgTech company N-Drip. “Most of this innovation will be driven by free-market capitalism, with important incentives from government and NGOs.

meaningful environmental progress has been made through market forces. In this century, America’s carbon dioxide emissions across fuel types have fallen to well below 5,000 million metric tons per year, from a peak of about 6,000 million in 2007, even as our inflation-adjusted G.D.P. has grown by over 50 percent and total population by about 17 percent.

1) Engagement with critics is vital. Insults and stridency are never good tools of persuasion, and trying to cow or censor climate skeptics into silence rarely works

the biggest single driver in emissions reductions from 2005 to 2017 was the switch from coal to natural gas for power generation, since gas produces roughly half the carbon dioxide as coal. This, in turn, was the result of a fracking revolution in the past decade, fiercely resisted by many environmental activists, that made the United States the world’s largest gas producer.

In the long run, we are likelier to make progress when we adopt partial solutions that work with the grain of human nature, not big ones that work against it

Renewables, particularly wind power, played a role. So did efficiency mandates.

The problem with our civilization isn’t overconfidence. It’s polarization, paralysis and a profound lack of trust in all institutions, including the scientific one

Devising effective climate policies begins with recognizing the reality of the social and political landscape in which all policy operates. Some thoughts on how we might do better:

They may not be directly related to climate change but can nonetheless have a positive impact on it. And they probably won’t come in the form of One Big Idea but in thousands of little ones whose cumulative impacts add up.

2) Separate facts from predictions and predictions from policy. Global warming is a fact. So is the human contribution to it. So are observed increases in temperature and sea levels. So are continued increases if we continue to do more of the same. But the rate of those increases is difficult to predict even with the most sophisticated computer modeling

3) Don’t allow climate to become a mainly left-of-center concern. One reason the topic of climate has become so anathema to many conservatives is that so many of the proposed solutions have the flavor, and often the price tag, of old-fashioned statism

4) Be honest about the nature of the challenge. Talk of an imminent climate catastrophe is probably misleading, at least in the way most people understand “imminent.”

A more accurate description of the challenge might be a “potentially imminent tipping point,” meaning the worst consequences of climate change can still be far off but our ability to reverse them is drawing near. Again, the metaphor of cancer — never safe to ignore and always better to deal with at Stage 2 than at Stage 4 — can be helpful.

5) Be humble about the nature of the solutions. The larger the political and financial investment in a “big fix” response to climate change on the scale of the Energiewende, the greater the loss in time, capital and (crucially) public trust when it doesn’t work as planned

6) Begin solving problems our great-grandchildren will face. Start with sea-level rise

We can also stop providing incentives for building in flood-prone areas by raising the price of federal flood insurance to reflect the increased risk more accurately.

7) Stop viewing economic growth as a problem. Industrialization may be the leading cause of climate change. But we cannot and will not reverse it through some form of deindustrialization, which would send the world into poverty and deprivation

8) Get serious about the environmental trade-offs that come with clean energy. You cannot support wind farms but hinder the transmission lines needed to bring their power to the markets where they are needed.

9) A problem for the future is, by its very nature, a moral one. A conservative movement that claims to care about what we owe the future has the twin responsibility of setting an example for its children and at the same time preparing for that future.

maybe most controversially, the Biden team added a “foreign direct product rule” that, as The Financial Times noted, “was first used by the administration of Donald Trump against Chinese technology group Huawei” and “in effect bars any U.S. or non-U.S. company from supplying targeted Chinese entities with hardware or software whose supply chain contains American technology.”

This last rule is huge, because the most advanced semiconductors are made by what I call “a complex adaptive coalition” of companies from America to Europe to Asia

The more we push the boundaries of physics and materials science to cram more transistors onto a chip to get more processing power to continue to advance artificial intelligence, the less likely it is that any one company, or country, can excel at all the parts of the design and manufacturing process. You need the whole coalition

The reason Taiwan Semiconductor Manufacturing Company, known as TSMC, is considered the premier chip manufacturer in the world is that every member of this coalition trusts TSMC with its most intimate trade secrets, which it then melds and leverages for the benefit of the whole.

“We do not make in the U.S. any of the chips we need for artificial intelligence, for our military, for our satellites, for our space programs” — not to mention myriad nonmilitary applications that power our economy. The recent CHIPS Act, she said, was our “offensive initiative” to strengthen our whole innovation ecosystem so more of the most advanced chips will be made in the U.S.

It managed to pilfer a certain amount of chip technology, including 28 nanometer technology from TSMC back in 2017.

Because China is not trusted by the coalition partners not to steal their intellectual property, Beijing is left trying to replicate the world’s all-star manufacturing chip stack on its own with old technologies

China can’t mass produce these chips with precision without ASML’s latest technology — which is now banned from the country.

Raimondo rejects the idea that the new regulations are tantamount to an act of war.

“The U.S. was in an untenable position,” she told me in her office. “Today we are purchasing 100 percent of our advanced logic chips from abroad — 90 percent from TSMC in Taiwan and 10 percent from Samsung in Korea.” (That IS pretty crazy, but it IS true.)

Until recently, China’s premier chip maker, Semiconductor Manufacturing International Company, had been thought to be stuck at mostly this chip level,

Imposing on China the new export controls on advanced chip-making technologies, she said, “was our defensive strategy. China has a strategy of military-civil fusion,” and Beijing has made clear “that it intends to become totally self-sufficient in the most advanced technologies” to dominate both the civilian commercial markets and the 21st century battlefield. “We cannot ignore China’s intentions.”

So, to protect ourselves and our allies — and all the technologies we have invented individually and collectively — she added, “what we did was the next logical step, to prevent China from getting to the next step.” The U.S. and its allies design and manufacture “the most advanced supercomputing chips, and we don’t want them in China’s hands and be used for military purposes.”

Our main focus, concluded Raimondo, “is playing offense — to innovate faster than the Chinese. But at the same time, we are going to meet the increasing threat they are presenting by protecting what we need to. It is important that we de-escalate where we can and do business where we can. We don’t want a conflict. But we have to protect ourselves with eyes wide open.”

China’s state-directed newspaper Global Times editorialized that the ban would only “strengthen China’s will and ability to stand on its own in science and technology.” Bloomberg quoted an unidentified Chinese analyst as saying “there is no possibility of reconciliation.”

Unlike store shelves that have to be physically rearranged, the online marketplace’s search engine surfaces what you want when you want it from a deep inventory of hundreds of millions of products. Meanwhile a big-box store can only carry approximately 100,000 different goods.

The marketplace model also helps Amazon shift more quickly to things people want to buy. Its hundreds of thousands of merchants scour search engine trends in real time to know which products they should be selling and when

Amazon’s revenue from third-party seller services—a category that includes commissions and fees for things like warehousing, packaging and delivery—increased 9% in the second quarter to $27.38 billion.

Another positive note was that subscription services revenue, which is mostly Prime memberships, grew 14% in the quarter, reversing three consecutive quarters of slowing growth—meaning shoppers still see value in the membership, despite a $20 price hike in February to $139 a year.

My high level of vaccine antibodies probably explains my success more than my behavior. I make some effort to avoid Covid, but have been far from perfect. And I’ve been potentially exposed at least twice: Once last December, when someone at a small holiday gathering I’d attended developed symptoms the next day, and more recently, when I shared a large indoor space with two people who later tested positive. But according to my lab work, I’ve never had even a silent infection.

But one piece of advice almost no one is giving? Be lucky. Pediatrician Neil Stone says that there’s no “secret” for staying Covid-19 free because there’s just too much luck involved.

As for me, I have some data that can, to an extent, quantify and explain my own good luck in avoiding Covid so far. I’m participating in a study on immunity which allowed me to learn that my blood still carries loads of antibodies induced by my vaccine and December booster shot, and no signs of any prior infection. Not everyone’s antibodies wane at the same rate, and in some people, the antibodies don’t wane much at all. (At some point it should become routine to collect this information to help people decide whether to get additional booster shots.)

It’s possible I was protected by my high antibodies, or that some quirk of air flow meant I never breathed in enough virus to get sick. Or perhaps I benefited from a different form of luck. There’s another facet to immunity called the innate immune system, which acts as a first line of defense and sometimes knocks out a virus or other pathogen before it replicates enough to elicit the production of antibodies. Good innate immunity might help explain something many of us have experienced — not getting a cold or flu even when sleeping in the same bed with the sick person through the whole illness.

Stress, diet, general health and even sunlight might all affect innate immunity. So could other factors. There’s so much we still don’t know about the immune system. And that’s one reason we talk about “luck.”

understanding how the luck works could help other people avoid Covid, whether for the first time or for the second or third time. Taking a closer look at what passed for luck helped researchers like Gary Taubes discover that public health had obesity all wrong, and the standard high carb/low fat diets were causing people to gain weight.

“People have faced higher prices and that is difficult, but that doesn’t explain why people have not cut back,” she said of a phenomenon known as revealed preference. “They have spent as if they see nothing but good times in front of them. So why are their actions so out of whack with their words?”

Many said their own finances were good enough — they had jobs, owned houses, made ends meet. But they felt as if they were “just getting by,” with “nothing left over.” Many felt angry and anxious over prices and the pandemic and politics.

Also, economists said, wages have increased alongside prices. Real median earnings for full-time workers are slightly higher than at the end of 2019, and for many low earners, their raises have outpaced inflation. But it’s common for people to think about prices at face value, rather than relative to their income, a habit economists call money illusion.

“The pandemic shattered a lot of illusions of control,” Professor Stevenson said. “I wonder how much that has made us more aware of all the places we don’t have control, over prices, over the housing market.”

Inflation weighed heavily on voters — nearly all of them mentioned frustration at the price of something they buy regularly.

Consumer prices were up 3.2 percent in October from the year before, a decline in the year-over-year inflation rate from more than 8 percent in mid-2022. But inflation “casts a long shadow on how people evaluate things,” said Lawrence Katz, an economist at Harvard. Some people may expect prices to return to what they were before — something that rarely happens

Those feelings may be driving attitudes about the economy, economists speculated, sounding more like their colleagues from another branch of social science, psychology.

Younger people — who were a key to President Biden’s win in 2020 but showed less support for him in the new poll — had concerns specific to their phase of life. In the poll, 93 percent of them rated the economy unfavorably, more than any other age group.

“Everyone thinks a wage increase is something they deserve, and a price increase is imposed by the economy on them,” Professor Katz said.

There’s a sense that it’s become harder to achieve the things their parents did, like buying a home. Houses are less affordable than at the height of the 2006 bubble, and less than half of Americans can afford one.

“More than likely, half my income will go toward rent,” he said. “I was really hoping on that student loan forgiveness.”

Yet overall, economists said, data shows that more people are quitting jobs to start better ones, moving to more desirable places because they can work remotely, and starting new businesses.

He said he makes almost $80,000, serving in the military and working as a DoorDash deliverer, yet feels he had more spending money a decade ago, when he was two pay grades lower.

he uncertainty Mr. Blanck and Ms. Linn share about the future ran through many voters’ stories, darkening their economic outlook.

“The degree of volatility that we’ve experienced from different events — from the pandemic, from inflation — leaves them not confident that even if objectively good things are going on, it’s going to persist,”

In response to the pandemic, the United States built an extensive welfare state, and it has since been dismantled. While wealth has increased for families across the income spectrum, data shows, and there are indications that inequality could be shrinking, the changes have been small relative to decades of growing inequality, leading to a sense for some that the system is rigged.

“When things are going well, that means rich people are getting richer and all of us are pretty much second,” said Manuel Zimberoff, 26, a manufacturing engineer in Philadelphia. “And if things are going poorly, rich people are still getting richer, and all of us are screwed.”

For roughly two decades, partisanship has increasingly been correlated with views about the economy: Research has shown that people rate the economy more poorly when their party is not in power. Nearly every Republican in the poll rated the economy unfavorably, and 59 percent of Democrats did.

He brought up U.S. funding in Ukraine and the Middle East. He wanted to know: Is that the reason our economy is “slowing down?” He wasn’t sure, but he thought it might be. He plans to vote for “the Republican, any Republican,” he said. “Democrats have disappointed me.”

a Bloomberg reporter saw only three semis among the vehicles blocking the Ambassador Bridge, which were mainly pickup trucks and private cars; photos taken Saturday also show very few commercial trucks.

this isn’t a grass-roots trucker uprising. It’s more like a slow-motion Jan. 6, a disruption caused by a relatively small number of activists, many of them right-wing extremists

At their peak, the demonstrations in Ottawa reportedly involved only around 8,000 people, while numbers at other locations have been much smaller.

it’s not hard to come up with numbers like $300 million or more per day; combine that with the disruption of Ottawa, and the “trucker” protests may already have inflicted a couple of billion dollars in economic damage

it’s roughly comparable to insurance industry estimates of total losses associated with the Black Lives Matter protests that followed the killing of George Floyd — protests that seem to have involved more than 15 million people.

In fact, the demonstrations were remarkably nonviolent; vandalism happened in a few cases, but it was relatively rare, and the damage was small considering the huge size of the protests.

By contrast, causing economic damage was and is what the Canadian protests are all about — because blocking essential flows of goods, threatening people’s livelihoods, is every bit as destructive as smashing a store window.

And to what end? The B.L.M. demonstrations were a reaction to police killings of innocent people; what’s going on in Canada is, on its face, about rejecting public health measures intended to save lives.

even that is mainly an excuse: What it’s really about is an attempt to exploit pandemic weariness to boost the usual culture-war agenda.

the U.S. right is loving it. People who portrayed peaceful protests against police killings as an existential threat are delighted by the spectacle of right-wing activists breaking the law and destroying wealth

Recent events have confirmed what many suspected: The right is perfectly fine, indeed enthusiastic, about illegal actions and disorder as long as they serve right-wing ends.

For the Russians on the ground in Ukraine, the worst is still ahead. For Putin to subdue Kyiv, a city of nearly four million, he will have to throw a significant level of combat power into the fight

It took the U.S. First Marine Division — the most elite combat troops in the world — nearly two months to conquer Fallujah, an Iraqi city about a tenth the size of Kyiv.
