The urgent necessity of asset stranding

A review of Overshoot: How the World Surrendered to Climate Breakdown

In 2023 delegates from around the world gathered for a 28th session of the Conference Of the Parties (COP), this time held in the United Arab Emirates. The official director of the mega-meeting, nominally devoted to mitigating the climate crisis caused by fossil fuel emissions, was none other than Sultan Al Jaber, CEO of the Abu Dhabi National Oil Company (ADNOC).

At the time, ADNOC was “in the midst of a thrust of expansion, planning to pour more than 1 billion dollars into oil and gas projects per month until 2030.” (Overshoot, page 253)

Overshoot, by Andreas Malm and Wim Carton, published by Verso, October 2024.

Sultan Al Jaber’s appointment was praised by climate envoy John Kerry of the United States, which was also committing a historic expansion of fossil fuel extraction.

The significance of COP being presided over by a CEO working hard to increase carbon emissions was not lost on Andreas Malm and Wim Carton. In that moment, they write,

“[A]ctive capital protection had been insinuated into the highest echelons of climate governance, the irreal (sic) turn coming full circle, the theatre now a tragedy and farce wrapped into one, overshoot ideology the official decor.” (Overshoot, p 254; emphasis mine)

What do Malm and Carton mean by “capital protection” and “overshoot”? “Capital protection” is the opposite of “asset stranding”, which would occur if trillions of dollars worth of fossil fuel reserves were “left in the ground,” unburned, unexploited. Yet as we shall see, the potential threat to capital goes far beyond even the trillions of dollars of foregone profits if the fossil fuel industry were rapidly wound down.

In Malm and Carton’s usage, “overshoot” has a different meaning than in some ecological theory. In this book “overshoot” refers specifically to carbon emissions rising through levels that will cause 1.5°C, 2°C, or other specified threshold for global warming. To apologists for overshoot, it is fine to blow through these warming targets temporarily, as long as our descendants later in the century draw down much of the carbon through yet-to-be commercialized technologies such as Bio-Energy with Carbon Capture and Storage (BECCS).

Overshoot, Malm and Carton say, is a dangerous gamble that will certainly kill many people in the coming decades, and collapse civilization and much of the biosphere in the longer term if our descendants are not able adequately clean up the mess we are bequeathing them. Yet overshoot is firmly integrated into the Integrated Assessment Models widely used to model the course of climate change, precisely because it offers capital protection against asset stranding.

Scientific models, “drenched in ideology”

If the global climate were merely a complex physical system it would be easier to model. But of course it is also a biological, ecological, social and economic system. Once it was understood that the climate was strongly influenced by human activity, early researchers understood the need for models that incorporated human choices into climate projections.

“But how could an economy of distinctly human making be captured in the same model as something like glaciers?,” Malm and Carton ask. “In the Integrated Assessment Models (IAMs), the trick was to render the economy lawlike on the assumptions of neoclassical theory ….” (p 56)

These assumptions include the idea that humans are rational, making their choices to maximize utility, in free markets that collectively operate with perfect information. While most people other than orthodox economists can recognize these assumptions as crude caricatures of human behaviour, this set of assumptions is hegemonic within affluent policy-making circles. And so it was the neoclassical economy whose supposed workings were integrated into the IAMs. 

While “every human artifact has a dimension of ideology,” Malm and Carton write, 

“IAMs were positively drenched in non-innocent ideological positions, of which we can quickly list a few: rationalism (human agents behave rationally), economism (mitigation is a matter of cost), presentism (current generations should be spared the onus), conservatism (incumbent capital must be saved from losses), gradualism (any changes will have to be incremental), and optimism (we live in the best of all possible economies). Together, they made ambitious climate goals – the ones later identified as in line with 1.5°C or 2°C – seem all but unimaginable.” (p 60; emphasis mine)

In literally hundreds of IAMs, they write, there was a conspicuous absence of scenarios involving degrowth, the Green New Deal, the nationalisation of oil companies, half-earth socialism, or any other proposal to achieve climate mitigation through radical changes to “business as usual.”

In the place of any such challenges to the current economic order was another formidable acronym: BECCS, “Bio-Energy with Carbon Capture and Storage.” No costly shakeups to the current economy were needed, because in the IAMs, the not-yet-commercialized BECCS was projected to become so widely implemented in the second half of the century that it would draw down all the excess carbon we are currently rushing to emit.

As the 21st century progressed and as warming thresholds such as 1.5°C or even 2°C grew dangerously close, overshoot, excused by the imagined future roll-out of BECCS, became a more attractive and dangerous concept. Due to the magic of IAMs incorporating overshoot, countries like Canada, the US, and other petrostates could declare climate emergencies, pledge their support to a 1.5°C ceiling – and simultaneously step up their fossil extraction efforts.

On June 17, 2019, the Canadian Parliament approved a motion declaring the country to be in a climate emergency. On June 18, 2019, the Government of Canada announced its approval of the Trans-Mountain Pipeline Expansion, for the purpose of bringing more tar sands crude to the BC coast for export.

At COP15 in Copenhagen in 2009, and most famously at the Paris Accord in 2015, countries could piously pledge their allegiance to stringent warming limits, while ensuring no binding commitments remained in the texts to limit the fossil fuel industry. Overshoot was the enabling concept: “Through this sleight of hand, any given target could be both missed and met and any missing be rationalised as part of the journey to meeting it ….” (p 87)

“The common capital of the class”

There is a good deal of Marxist rhetoric in Overshoot, and Malm and Carton are able guides to this often tangled body of political-economic theory. On some subjects they employ these ideas to clarifying effect.

Given the overwhelming consensus of climatologists, plus the evidence in plain sight all around us, that the climate emergency is rapidly growing more severe, why is there still such widespread resistance to radical economic change?

The opposition to radical change comes not only from fossil fuel company owners and shareholders. Rather, the fierce determination to carry on with business as usual comes from many sectors of industry, the financial sector, nearly all policy-makers, and most of the media elite.

As Malm and Carton explain, if firm policies were put in place to “leave fossil fuels in the ground”, stranding the assets of fossil fuel companies, there would be “layer upon layer” of value destruction. The first layer would be the value of the no-longer usable fossil reserves. The next layer would be the vast network of wells, pipelines, refineries, even gas stations which distribute fossil fuel. A third would be the machinery now in place to burn fossil fuels in almost every other sector of industrial production. The economic valuations of these layers would crash the moment “leaving fossil fuels in ground” became a binding policy.

Finally, the above layers of infrastructure require financing. “Increased fixed capital formation,” Malm and Carton write, “necessitates increased integration into equity as well as credit markets – or, to use a pregnant Marxian phrase, into ‘the common capital of the class.’” (p 133)

The upshot is that “any limitations on fossil fuel infrastructure would endanger the common capital of the class by which it has been financed.” (p 133-134) And “the class by which it has been financed,” of course, is the ruling elite, the small percentage of people who own most of corporate equity, and whose lobbyists enjoy regular access to lawmakers and regulators. 

The elite class which owns, finances and profits from fossil production also happens to be responsible for a wildly disproportionate amount of fossil fuel consumption. Overshoot cites widely publicized statistics that show that the richest ten per cent of humanity is responsible for half of the emissions, while the poorest fifty percent of humanity emits only about a tenth of the emissions. They add, 

“It was not the masses of the global South that, suicidally, tipped the world into 1.5°C. In fact, not even the working classes of the North were party to the process: between 1990 and 2019, per capita emissions of the poorest half of the populations of the US and Europe dropped by nearly one third, due to ‘compressed wages and consumption.’ The overshoot conjuncture was the creation of the rich, with which they capped their victory in the class struggle.” (p 225-226)

Stock, flow and the labour theory of value

Malm and Carton go on to explain the economic difference between fossil fuel energy and solar-and-wind energy, through the simple lens of Marx’ labour theory of value. In my opinion this is the least successful section of Overshoot.

First, the authors describe fossil fuel reserves as “stocks” and the sunshine and wind as “flows”. That’s a valid distinction, of significance in explaining some of the fundamental differences in these energy sources.

But why has fossil fuel extraction recently been significantly more profitable than renewable energy harvesting?

The key fact, Malm and Carton argue, is that “the flow [solar and wind energy] appears without labour. … [T]he fuel is ripe for picking prior to and in proud disregard of any process of production. ‘Value is labour,’ Marx spells out …. It follows that the flow cannot have value.”

They emphasize the point with another quote from Marx: “‘Where there is no value, there is eo ipso nothing to be expressed in money.’”

“And where there is nothing to be expressed in money,” they conclude, “there can be no profit.” (p 208-209) That is why the renewable energy business will never supply the profits that have been earned in fossil extraction.

This simple explanation ignores the fact that oil companies aren’t always profitable; for a period of years in the last decade, the US oil industry had negative returns on equity.1 Clearly, one factor in the profitability of extraction is the cost of extraction, while another is the price customers are both willing and able to pay. When the former is as high as or higher than the latter, there are no profits even for exploitation of stocks.

As for business opportunities derived from the flow, Malm and Carton concede that profits might be earned through the manufacture and installation of solar panels and wind turbines, or the provision of batteries and transmission lines. But in their view these profits will never come close to fossil fuel profits, and furthermore, any potential profits will drop rapidly as renewable sources come to dominate the electric grid. Why? Again, their explanation rests on Marx’s labour theory of value:

“The more developed the productive forces of the flow, the more proficient their capture of a kind of energy in which no labour can be objectified, the closer the price and the value and the profit all come to zero.” (page 211)

Does this sound fantastically utopian to you? Imagine the whole enterprise – mining, refining, smelting, transporting, manufacturing and installation of PV panels and wind turbines, extensions of grids, and integration of adequate amounts of both short- and long-term storage – becoming so “proficient [in] their capture of energy” that the costs are insignificant compared to the nearly limitless flow of clean electricity. Imagine that all these costs become so trivial that the price of the resulting electricity approaches zero.

As a corrective to this vision of ‘renewable electricity too cheap to meter,’ I recommend Vince Beiser’s Power Metal, reviewed here last week.

Malm and Carton, however, are convinced that renewably generated electricity can only get cheaper, and furthermore can easily substitute for almost all the current uses of fossil fuels, without requiring reductions in other types of consumption, and all within a few short years. In defense of this idea they approvingly cite the work of Mark Jacobson; rather than critique that work here, I’ll simply refer interested readers to my review of Jacobson’s 2023 publication No Miracles Needed.

Energy transition and stranded assets

Energy transition is not yet a reality. Malm and Carton note that although renewable energy supply has grown rapidly over the past 20 years, fossil energy use has not dropped. What we have so far is an energy addition, not an energy transition.

Not coincidentally, asset stranding likewise remains “a hypothetical event, not yet even attempted.” (p 192)

The spectre of fossil fuel reserves and infrastructure becoming stranded assets has been discussed in the pages of financial media, ever since climate science made it obvious that climate mitigation strategies would indeed require leaving most known fossil reserves in the ground, i.e., stranding these assets. (One of the pundits sounding a warning was Mark Carney, formerly a central banker and now touted as a contender to replace Justin Trudeau as leader of the Liberal Party of Canada; he makes an appearance in Overshoot.)

Yet there is no evidence the capitalist class collectively is losing sleep over stranded assets, any more than over the plight of poor farmers being driven from their lands by severe floods or droughts.

As new fossil fuel projects get more expensive, the financial establishment has stepped up its investment in such projects. In the years immediately following the Paris Agreement – whose 1.5°C warming target would have required stranding more than 80 per cent of fossil fuel reserves – a frenzy of investment added to both the reserves and the fixed capital devoted to extracting those reserves:

“Between 2016 and 2021, the world’s sixty largest banks poured nearly 5 trillion dollars into fossil fuel projects, the sums bigger at the end of this half-decade than at its beginning.” (p 20) 

The implications are twofold: first, big oil and big finance remain unconcerned that any major governments will enact strong and effective climate mitigation policies – policies that would put an immediate cap on fossil fuel exploitation plus a binding schedule for rapid reductions in fossil fuel use over the coming years. They are unconcerned about such policy possibilities because they have ensured there are no binding commitments to climate mitigation protocols.

Second, there are far more assets which could potentially be stranded today than there were even in 2015. We can expect, then, that fossil fuel interests will fight even harder against strong climate mitigation policies in the next ten years than they did in the last ten years. And since, as we have seen, the layers of stranded assets would go far beyond the fossil corporations themselves into ‘the common capital of the class’, the resistance to asset stranding will also be widespread.

Malm and Carton sum it up this way: “We have no reliable friends in the capitalist classes. … any path to survival runs through their defeat.” (p 236)

The governments of the rich countries, while pledging their support for stringent global warming limits, have through their deeds sent us along the path to imminent overshoot. But suppose a major coal- or oil-producing jurisdiction passed a law enacting steep cutbacks in extraction, thereby stranding substantial fossil capital assets.

“Any measure significant enough to suggest that the fears harboured for so long are about to come true could pop the bubble,” Malm and Carton write. “[T]he stampede would be frenzied and unstoppable, due to the extent of the financial connections ….” (p 242)

Such a “total breakdown of capital” would come with drastic social risks, to be sure – but the choice is between a breakdown of capital or a breakdown of climate (which would, of course, also cause a breakdown of capital). Could such a total breakdown of capital still be initiated before it’s too late to avoid climate breakdown? In a book filled with thoughtful analysis and probing questions, the authors close by proposing this focus for further work:

“Neither the Green New Deal nor degrowth or any other programme in circulation has a plan for how to strand the assets that must be stranded. … [This] is the point where strategic thinking and practise should be urgently concentrated in the years ahead.” (p 244)

Critical metals and the side effects of electrification

A review of Power Metal: The Race for the Resources That Will Shape The Future

Also published on Resilience.

“The energy transition from fossil fuels to renewables is a crucial part of the cure for climate change,” writes Vince Beiser on page one of his superb new book Power Metal. “But it’s a cure with brutal side effects.”

The point of Beiser’s stark warning is not to downplay the urgency of switching off fossil fuels, nor to assert that a renewable energy economy will be a greater ecological menace than our current industrial system.

Power Metal by Vince Beiser, published November 2024 by Riverhead Books.

But enthusiasm for supposedly clean and free solar and wind energy must be tempered by a realistic knowledge of the mining and refining needed to produce huge quantities of solar panels, wind turbines, transmission lines, electric motors, and batteries.

In Power Metal, Beiser explains why we would need drastic increases in mining of critical metals – including copper, nickel, cobalt, lithium, and the so-called “rare earths” – if we were to run anything like the current global economy solely on renewable electricity.

Beyond merely outlining the quantities of metals needed, however, he provides vivid glimpses of the mines and refineries where these essential materials are extracted and transformed into usable commodities. His journalistic treatment helps us understand the ecological impacts of these industries as well as the social and health impacts on the communities where this work is done, often in horrible conditions.

While cell phones and computers in all their billions each contain small quantities of many of the critical metals, the much-touted electric vehicle transition has a deeper hunger. Take nickel. “Stainless steel consumes the lion’s share of nickel output,” Beiser writes, “but batteries are gaining fast.” (page 69)

“The battery in a typical Tesla,” he adds, “is as much as 80 percent nickel by weight. The battery industry’s consumption of nickel jumped 73 percent in 2021 alone.” (p 69)

And so on, down the list: “a typical EV contains as much as one hundred seventy-five pounds of copper.” ( p 45)

“Your smartphone probably contains about a quarter ounce of cobalt; electric vehicle batteries can contain upwards of twenty-four pounds.” (p 77)

Extending current trend lines leads to the following prediction:

“By 2050, the International Energy Agency estimates, demand for cobalt from electric vehicle makers alone will surge to nearly five times what it was in 2022; nickel demand will be ten times higher; and for lithium, fifteen times higher ….” (p 4)

If those trend lines hold true – and that’s a big “if” – the energy transition will come with high ecological costs.

The historic leading producer of nickel, Norilsk in Siberia, “is one of the most ecologically ravaged places on Earth.” (p 70) Unfortunately a recent contender in Indonesia, where the nickel ore is a lower quality, may be even worse:

“Nickel processing also devours huge amounts of energy, and most of Indonesia’s electricity is generated by coal-fired plants. That’s right: huge amounts of carbon-intensive coal are being burned to make carbon-neutral batteries.” (p 74)

The Bayan Obo district in China is the world’s major producer of refined rare earths – and “not by coincidence, it is also one of the most polluted areas on the planet. …” (p 28)

Ideally we’d want the renewable energy supply chain to meet three criteria: cheap, clean, and fair. As it is, we’re lucky to get one out of three.

Mining of critical metals can only take place in particular locations – blessed or cursed? – where such elements are somewhat concentrated in the earth’s crust. When there is a choice of nations for suppliers, the global economy leans to nations with lax environmental and labour standards as well as low wages.

There are no geographic restrictions on processing, however, and that’s why China’s dominance in critical metal processing far exceeds its share of world reserves.

The Mountain Pass mine in California is rapidly expanding extraction of rare earths. But the US facility is only able to produce a commodity called bastnaesite, which contains all the rare earths mixed together. To separate the rare earth elements one from another, the mine operator tells Beiser, the bastnaesite must be shipped to China: “ There’s no processing facilities anywhere outside of China that can handle the scale we need to be producing.” (p 36)

The story is similar for other critical metals. Cobalt, for example, is mined in famously brutal conditions in the Democratic Republic of Congo, and then sent to China for processing.

Could both the mining and the processing be done in ways that respect the environment and respect the health and dignity of workers? Major improvements in these respects are no doubt possible – but will likely result in a significantly higher price for renewable energy technologies. Our ability to pay that price, in turn, will be greatly influenced by how parsimoniously or how profligately we use the resulting energy.

Recycling to the rescue?

Is the messy extraction and processing of critical metals just a brief blip on a rosy horizon? Proponents of recycling sometimes make the case that the raw materials for a renewable energy economy will only need to be mined once, after which recycling will take over.

Beiser presents a less optimistic view. A complex global supply chain manufactures cars and computers that are composites of many materials, and these products are then distributed to every corner of the world. Separating out and re-concentrating the various commodities so they can be recycled also requires a complex supply chain – running in reverse.

“Most businesses that call themselves metal recyclers don’t actually turn old junk into new metal,” Beiser writes. “They are primarily collectors, aggregators.” (p 130) He takes us into typical work days of metal collectors and aggregators in his hometown of Vancouver as well as in Lagos, Nigeria. In these and other locations, he says, the first levels of aggregation tend to be done by people working in the informal economy.

In Lagos, workers smash apart cell phones and computers, and manually sort the circuit boards into categories, before the bundles of parts are shipped off to China or Europe for the next stage of reverse manufacturing:

“Shredding or melting down a circuit board and separating out those tiny amounts of gold, copper, and everything else requires sophisticated and expensive equipment. There is not a single facility anywhere in Africa capable of performing this feat.” (p 145)

Because wages are low and environmental regulations lax in Nigeria and Ghana, it is economically possible to collect and aggregate almost all the e-waste components there. Meanwhile in the US and Europe, “fewer than one in six dead mobile phones is recycled.” (p 146)

Cell phones are both tiny and complicated, but what about bigger items like solar panels, wind turbine blades, and EV batteries?

Here too the complications are daunting. It is currently far cheaper in the US to send an old solar panel to landfill than it is to recycle it. There isn’t yet a cost-effective way to separate the composite materials in wind turbine blades for re-use.

Lithium batteries add explosive danger to the complications of recycling: 

“If they’re punctured, crushed, or overheated, lithium batteries can short-circuit and catch on fire or even explode. Battery fires can reach temperatures topping 1,000 degrees Fahrenheit [538°C], and they emit toxic gases. Worse, they can’t be extinguished by water or normal firefighting chemicals. (p 153)

Perhaps it’s not surprising that only 5% of lithium-ion batteries are currently recycled. (p 151)

Given the costs, dangers, and complex supply chain needed, Beiser says, recycling is not “the best alternative to using virgin materials. In fact, it’s one of the worst.” (p 16)

Far better, he argues in the book’s closing section, are two other “Rs” – “reuse” and “reduce.”

Simply using all the cell phones in Europe for one extra year before junking them, he says, would avoid 2.1 million metric tons of carbon dioxide emissions per year –comparable to taking a million cars off the road.

Speaking of taking cars off the road, Beiser writes, “the real issue isn’t how to get more metals into the global supply chain to build more cars, it’s how to get people to where they want to go with fewer cars.” (p 186)

Given the high demands for critical metals involved in auto manufacturing, Beiser concludes that “the most effective single way that we as individuals can make a difference is this: Don’t buy a car. Not even an electric one.” (p 182) He might have added: if you do buy a car, get one that’s no bigger or heavier than needed for your typical usage, instead of the ever bulkier cars the big automakers push.

In response to projections about how fast we would need to convert the current world economy to renewable energy, Beiser fears that it may not be possible to mine critical metals rapidly enough to stave off cataclysmic climate change. If we dramatically reduce our demands for energy from all sources, however, that challenge is not as daunting:

“The less we consume, the less energy we need. The less energy we use, the less metal we need to dig up …. Our future depends. in a literal sense, on metal. We need a lot of it to stave off climate change, the most dangerous threat of all. But the less of it we use, the better off we’ll all be.” (p 204-205)

  • * *

“Energy transition” is a key phrase in Power Metal – but does this transition actually exist? Andreas Malm and Wim Carton make the important point that both “energy transition” and “stranded assets” remain mere future possibilities, each either a fond dream or a nightmare depending on one’s position within capitalist society. All the renewable energy installations to date have simply been additions to fossil energy, Malm and Carton point out, because fossil fuel use, a brief drop during the pandemic aside, has only continued to rise.

We turn to Malm and Carton’s thought-provoking new book Overshoot in our next installment.

The concentrated ills of concentrated agribusiness

A review of Barons: Money, Power, and the Corruption of America’s Food Industry.

Also published on Resilience.

If you are a government-approved American hog farmer, you drive: a) a dusty pickup truck, from your barn to your local small-town feed store; b) a huge articulated tractor, through your thousand-acre fields of corn and soybeans; c) a private jet, which you fly from your midwestern corporate headquarters to a second or third home in Florida.

Barons, by Austin Frerick, published by Island Press, March 2024.

If you’ve read Austin Frerick’s new book Barons (Island Press, March 2024), you’ll pick the private jet. The hog farmer won’t drive to a small-town feed store, because small towns in agricultural areas are losing most of their businesses. The hog farmer won’t use a big tractor to till fields of corn and soybeans; as a hog specialist who raises no grain, he or she will buy feed “inputs” from big grain farmers who raise no animals.

But as two prominent US Department of Agriculture secretaries advocated, farmers should “get big or get out”. And a hog farmer who has really “got big” will want that private jet, either to get to a second home on the Gulf Coast or to make quick trips to Washington to lobby for subsidies and tax breaks.

In his highly readable book, Frerick describes the businesses of barons who dominate seven sectors of the US food industry. In the process he illuminates much in recent American history and goes a long way towards diagnosing environmental ills, socio-economic ills, and the ill health of so many food consumers.

Although two of the barons, Cargill Inc. and JAB Holding Company, are well over a hundred years old, all seven barons have seen explosive growth in the 40 years since the US government switched to very lax anti-trust regulations. Except for JAB (a little-known Luxembourg-based company that has recently swallowed coffee supply chains around the world), all the highlighted barons are US-based, and all are very much involved in international trade.

One of the companies is neither a grower, processor, nor retailer of food – its core businesses are in marketing and in owning and licensing genetics. Driscoll’s is the major brand of strawberries and several other berries sold in supermarkets in the US as well as in Canada. (Frerick writes that they control about one-third of the US berry market.) The company buys from 750 growers in two dozen countries, employing more than one hundred thousand people. The growers work to Driscoll’s specifications, but Driscoll’s has no legal responsibility to those hundred thousand workers.

Now that American consumers have learned to buy fresh – albeit nearly tasteless – fruit twelve months of the year, it’s essential for Driscoll’s to have suppliers in countries with different seasons. This has other business advantages, Frerick writes: “the Driscoll’s model is based on shifting farming out of the country to companies that don’t need to worry about US minimum wage laws or environmental regulations.”

For two of the barons profiled, most of the production as well as most of the environmental damage occurs closer to home. Jeff and Deb Hansen, who own that private jet from the opening paragraph, rule an empire known as Iowa Select which brings five million pigs to market each year. “Today,” French writes, “Iowa raises about one-third of the nation’s hogs, about as many as the second-, third-, and fourth-ranking states combined.”

Dairy barons Sue and Mike McCloskey own a vast complex in Indiana called Fair Oaks Farms. Besides being an (indoor) home to 36,000 dairy cows, and the midwest’s largest agri-tourism destination, Fair Oaks produces about 430,000 gallons of manure every day.

The huge hog, chicken, dairy or beef operations favoured by the current rules of the game share this problem – they produce far more manure than can be safely used to augment local soils. The result, in many locations across the country, is polluted groundwater, runoff that disrupts river and lake ecosystems – and an overpowering stench for residents unlucky enough to live just downwind.

For workers in the hog, dairy, berry, slaughter, and grocery businesses profiled by Frerich, working conditions are often dangerous and the pay is low. The book reflects on Upton Sinclair’s century-old classic The Jungle, in which immigrant workers toil for meagre wages in filthy and dangerous Chicago slaughterhouses. In the decades after Sinclair’s book became a runaway bestseller, workers unionized and working conditions and wages in slaughterhouses improved dramatically. Today, however, many of the unions have been defeated, many slaughterhouses have moved to small towns where there is little other opportunity for employment, and most workers once again are new immigrants who have little ability to fight back against employers.

The most widely recognized name in Barons is Walmart. The mega-retailer is far and away the largest grocer in the US. As such, there are obvious advantages in buying products in huge, uniform quantities – in short, products that barons in the hog, dairy, grain, and berry sectors are ideally suited to provide. It matters not whether these products are truly nutritious. What matters is whether the products are cheap and, in line with WalMart’s directives to suppliers, cheaper year after year. Still, French explains, not cheap enough for WalMart’s own employees to afford – WalMart employees in many states require government assistance just to feed their families.

Barons is not a long book – under 200 pages, not including the footnotes – but Frerick covers a lot of ground. He does not spend a lot of time discussing solutions, however, beyond some very good ideas sketched briefly in the Conclusion. Still, for people not already deeply familiar with industrial agribusiness and its associated environmental, labour, health and political ills, Barons is a compelling read.

Essential voices for the turn away from car dependency

A review of When Driving Is Not An Option

Also published on Resilience

In forward-thinking municipalities across North America, elected officials and staff members can learn important lessons by taking on the Week Without Driving Challenge. As Anna Letitia Zivarts describes it, “participants have to try to get around for a week without driving. They can take transit, walk, roll, bike, or ask or pay for rides as they try to keep to their regular schedules ….”

When Driving Is Not An Option, published by Island Press, May 2024

In most municipalities, the challenge leads to a difficult but eye-opening week. That’s because in most areas getting around without driving is inconvenient, dangerous, very time-consuming, or next to impossible. As Zivarts writes,

“Even for participants who might already bike, walk or take transit for some of their weekly trips, we’ve heard that the experience has helped them comprehend the difference between taking the easy trips and taking all trips without driving.” (all quotes from When Driving Is Not An Option, Island Press, May 2024.)

Zivarts is a low-vision mom with the neurological condition nystagmus, and a wealth of information and insight about mobility. She started the Disabled Mobility Initiative in Washington state in 2020. “My first goal was making nondrivers visible,” she writes. “I was tired of hearing from elected leaders that ‘everyone’ in their communities drove, so spending more money on bus service or sidewalks just wasn’t necessary. I knew it wasn’t true ….”

In fact, many studies have shown that in most areas of the US, approximately 30% of residents do not drive. When Driving Is Not An Option makes clear that nondrivers are a varied group. Some don’t drive because they have a disability, some because they are too young to drive, some because they can’t afford to drive, some because they have entered the last seven to ten years of life during which an average American can no longer drive safely.

If transportation departments and urban planning staff do not include the voices of nondrivers, they are unlikely to develop policies and infrastructure that will reflect the needs of their whole communities.

In particular, Zivarts notes, planning departments must take care to listen to involuntary as well as voluntary nondrivers. She describes voluntary nondrivers as “people who have the financial resources, immigration status, and physical ability to own and drive a vehicle but choose not to.”

While she makes a strong case for a coalition that includes both voluntary and involuntary drivers, her book highlights “the expertise and lived experience … that comes from involuntary non-drivers, with an emphasis on the expertise of low-income, Black, Brown, immigrant, and disabled people, caregivers, and queer and trans people.” And she does a superb job of bringing us the insights from this wealth of expertise.

For much of my adult life I’ve been among the voluntary nondrivers. I have also had periods when due to disability I’ve been unable to drive, and as a senior I anticipate a time, coming soon, when I won’t be able to drive. But in recounting the experiences of the wide range of nondrivers she has worked with, Zivarts offers many perspectives that were new to me.

The problems and shortcomings – with existing infrastructure, municipal planning policies, traffic engineering standards, and university curricula for would-be planners and engineers – are manifold. Zivarts’ book is excellent in describing specific problems, and equally good at linking the issues of mobility justice to other struggles. So we learn about the connections between car-dependent transport policies and housing affordability, the inequitable distribution of environmental hazards, and the challenges of climate mitigation and adaptation.

The book’s subtitle is “steering away from car dependency”, and to accomplish that goal we need not just clear knowledge but also an effective coalition that draws on as many groups as possible. Zivarts quotes former Seattle mayor Mike McGinn:

“Politics runs on power, and those defending and benefiting from the status quo have power. Whether those directly benefiting from the billions spent on road expansion or those who have their transportation choices and convenience deeply subsidized, not just by dollars, but by the lost lives, lost health, and lost opportunity of those most damaged by overbuilt roads and pollution. To beat that kind of entrenched privilege and power takes more than white papers, it takes organizing.”

Zivarts lays out the stakes and the hope in a concluding paragraph that needs to be quoted in full:

“As the sky turns orange, the storms get stronger, and the waves higher, we are reminded of the immediacy of the threat and the moral prerogative to disrupt failed mobility and land use systems that are locking us into decades of carbon emissions. We also need to be reminded of the immediate daily and cumulative public health and environmental harms from tire dust, noise pollution, and traffic violence/enforcement, harms that wealthier, Whiter, nondisabled people are largely able to avoid. But those of us who can’t drive, because of disability, age, or income, see every day how automcobility is failing us. And we also believe that it must be changed. With our guidance, and a recognition of this leadership, we can and will create a different future.”

Do Ruddy Turnstones ask Red Knots for directions?

A review of The Internet of Animals: Discovering the Collective Intelligence of Life on Earth. 

Also published on Resilience.

A half-century ago, radio telemetry pioneer Bill Cochran heard something surprising while listening to migrating songbirds: when a Swainson’s Thrush called, a Veery answered. 

The Internet of Animals, by Martin Wikelski, 272 pages, published by Greystone Books on May 14, 2024.

This observation helped inspire a lifetime’s work for Cochran as well as for the much younger scientist and author Martin Wikelski. In The Internet of Animals, Wikelski recounted one of the many unconventional theories suggested by the Thrush-Veery call-and-response:

“The constant chirping back and forth in the night sky indicated that even though the birds had some innate tendency to migrate coded into their genes, they still communicated constantly on their journey. An even more radical interpretation of Bill’s data was that the only innate tendency the birds needed to have in their genes would be the drive to fly toward warmer areas in fall. … All the birds would need to do to find their way south to Central and South America would be to follow others flying along the nocturnal highway.” (The Internet of Animals, page 17)

Wikelski’s book, to be released on May 14, describes many successful radio telemetry projects, and offers tantalizing hints at what we might learn if the promise of the far more ambitious “Internet of Animals” is realized. But the hurdles to be surmounted are daunting.

For example, scientists around the world have had to develop communication tags that are light enough to be comfortable for diverse species of animals, durable enough to last an animal’s lifetime, powerful enough to communicate with orbiting satellites, and cheap enough to be manufactured in the tens or hundreds of thousands.

The current versions of the tags typically contain: a GPS receiver, so that the tag can report its geographic position at any time; sensors that measure acceleration and magnetic fields in three dimensions; temperature, humidity and altitude sensors that report what kind of weather the animal is coping with; a battery to power a transmitter to send all this data to a satellite up to 465 miles (750 km) away; and a tiny solar panel to keep the battery charged. In Wikelski’s summary, “In just two decades we went from a battery-powered collar with a beeping transmitter with a limited life to an intelligent smartphone-style ear tag powered by the sun that an animal could wear all its life.” (p. 151)

No less daunting has been the challenge of securing cooperation from the space science establishments in several countries, some of whom are now in military conflict.

For years the team worked on permission to attach an antenna to the International Space Station. The antenna was installed and tested, and in 2021 “we started to get amazing data”:

“Our red-footed falcons were on their way from Angola back to Hungary; the Hudsonian godwits were making their nonstop flights from Chile across the Galápagos and Guatemala into Texas; the supposedly stationary black coucals, an African cuckoo, were migrating more than 620 miles (1,000 km) from southern Tanzania to northern Democratic Republic of Congo ….” (p. 151)

And then, in early 2022, Russia invaded Ukraine, scuttling scientific co-operation between Russia, Western Europe and the US. Wikelski’s team had to devise a new method for receiving transmissions, settling on the use of CubeSat satellites yet to be launched. 

A Long-Billed Dowitcher, left, and Hudsonian Godwit, right, at Bowmanville Marsh on the north shore of Lake Ontario, October 5, 2022. Hudsonian Godwits, part of a family of ultra-long-distance flyers, are thought to make the migration between arctic and sub-arctic Canada and southern South America with as little as one rest stop. The appearance of this bird brought people from all across southern Ontario, many of them hoping to see a rare visitor for the first time. The Long-Billed Dowitchers nest in the western Canadian arctic and on the Alaska coasts, but they migrate only as far as the southern US and Mexico for the winter.

In his first discussions of a worldwide animal-tracking system made possible through satellites, Wikelski wryly recalls, he thought that it could be implemented in four years. He made that guess in 2003; if all goes well the system will start living up to its potential later this year, after the launch of a CubeSat antenna device. The hope is to have a second CubeSat receiver in orbit in 2025, and a third in 2026. “The goal,” he writes “is to have enough receivers in space to deliver near real-time data transmission ….” (p 215)

The Internet of Animals could give us much greater understanding of the behaviours of many animal species. In Wikelski’s vision, however, the benefits both to animals and to humans will go far beyond merely learning more about migration routes and timing.

If we can follow the daily movements of many animals from birth to death, he writes, we’ll have much better understanding of the decisions they must make and the challenges they must face – and therefore we’ll be better able to take effective actions to protect many species and the environments they live in.

It is also possible that through changes in behaviour, animals far from the sight of any humans may give us advance warning of potential new pandemics, or earthquakes, or severe weather:

“[I]f collectively animals tell us that something has changed in the environment, that their world now feels more dangerous, then we should listen. … [T]he natural intelligence of animals, the collective interaction of the most intelligent sensors we have on this planet, is perhaps our most important early warning system to help us anticipate natural catastrophes, at least on a local level.” (p 184)

One of the mentors Wikelski credits with inspiring the Internet of Animals was radio astronomer George Swenson. Much of Swenson’s career was spent developing instruments capable of collecting and sifting through radio waves that might turn out to be communications from an extraterrestrial intelligence.

Yet the legacy of Swenson’s work, Wikelski writes, might be that we get in touch with another intelligence, the collective intelligence of the many other animals that share this planet with us:

“Listening to animals might actually change our human way of thinking more profoundly than any unlikely message from outer space. As we start receiving messages from animals and truly listen to them, humans would also be more disposed to losing their culturally ingrained perception (at least in the Western world) that they are the God-give pinnacle of all life forms.” (p. 221) 

If such an enlightenment occurs, Wikelski believes the Anthropocene could be succeeded by “the Interspecies Age,” in which “we will be considering other living species when we make decisions about what happens next on our planet.”

“We are going to link the knowledge these other species have to our own knowledge,” he adds. “We are going to become partners.” (p 182)

The Internet of Animals relies on the latest products of high-tech manufacturing, and it is vulnerable to the turbulence of human power struggles. But at its heart the project is the life’s work of dedicated scientists simply doing their best to learn from animals.

Counting the here-and-now costs of climate change

A review of Slow Burn: The Hidden Costs of a Warming World

Also published on Resilience.

R. Jisung Park takes us into a thought experiment. Suppose we shift attention away from the prospect of coming climate catastrophes – out-of-control wildfires, big rises in sea levels, stalling of ocean circulation currents – and we focus instead on the ways that rising temperatures are already having daily impacts on people’s lives around the world.

Might these less dramatic and less obvious global-heating costs also provide ample rationale for concerted emissions reductions?

Slow Burn by R. Jisung Park is published by Princeton University Press, April 2024.

Park is an environmental and labour economist at the University of Pennsylvania. In Slow Burn, he takes a careful look at a wide variety of recent research efforts, some of which he participated in. He reports results in several major areas: the effect of hotter days on education and learning; the effect of hotter days on human morbidity and mortality; the increase in workplace accidents during hotter weather; and the increase in conflict and violence as hot days become more frequent.

In each of these areas, he says, the harms are measurable and substantial. And in another theme that winds through each chapter, he notes that the harms of global heating fall disproportionately on the poorest people both internationally and within nations. Unless adaptation measures reflect climate justice concerns, he says, global heating will exacerbate already deadly inequalities.

Even where the effect seems obvious – many people die during heat waves – it’s not a simple matter to quantify the increased mortality. For one thing, Park notes, very cold days as well as very hot days lead to increases in mortality. In some countries (including Canada) a reduction in very cold days will result in a decrease in mortality, which may offset the rise in deaths during heat waves.

We also learn about forward mortality displacement, “where the number of deaths immediately caused by a period of high temperatures is at least partially offset by a reduction in the number of deaths in the period immediately following the hot day or days.” (Slow Burn, p 85) 

After accounting for such complicating factors, a consortium of researchers has estimated the heat-mortality relationship through the end of this century, for 40 countries representing 55 percent of global population. Park summarizes their results:

“The Climate Impact Lab researchers estimate that, without any adaptation (so, simply extrapolating current dose-response relationships into a warmer future), climate change is likely to increase mortality rates by 221 per 100,000 people. … But adaptation is projected to reduce this figure by almost two-thirds: from 221 per 100,000 to seventy-three per 100,000. The bulk of this – 78 percent of the difference – comes from higher incomes.” (pp 198-199)

Let’s look at these estimates from several angles. First, to put the lower estimate of 73 additional deaths per 100,000 people in perspective, Park notes an increase in mortality of this magnitude would be six times larger than the US annual death toll from automobile crashes, and roughly tw0-thirds the US death toll from COVID-19 in 2020. An increase in mortality of 73 per 100,000 is a big number.

Second, it seems logical that people will try to adapt to more and more severe heat waves. If they have the means, they will install or augment their air-conditioning systems, or perhaps they’ll buy homes in cooler areas. But why should anyone have confidence that most people will have higher incomes by 2100, and therefore be in a better position to adapt to heat? Isn’t it just as plausible that most people will have less income and less ability to spend money on adaptation?

Third, Park notes that inequality is already evident in heat-mortality relationships. A single day with average temperature of 90°F (32.2°C) or higher increases the annual mortality in South Asian countries by 1 percent – ten times the heat-mortality increase that the United States experiences. Yet within the United States, there is also a large difference in heat-mortality rates between rich and poor neighbourhoods.

Even in homes that have air-conditioning (globally, only about 30%), low-income people often can’t afford to run the air-conditioners enough to counteract severe heat. “Everyone uses more energy on very hot and very cold days,” Park writes. “But the poor, who have less slack in their budgets, respond more sparingly.” (p 191)

A study in California found a marked increase in utility disconnections due to delinquent payments following heat waves. A cash-strapped household, then, faces an awful choice: don’t turn up the air-conditioner even when it’s baking hot inside, and suffer the ill effects; or turn it up, get through one heat wave, but risk disconnection unless it’s possible to cut back on other important expenses in order to pay the high electric bill.

(As if to underline the point, a headline I spotted as I finished this review reported surges in predatory payday loans following extreme weather.)

The drastic adaptation measure of relocation also depends on socio-economic status. Climate refugees crossing borders get a lot of news coverage, and there’s good reason to expect this issue will grow in prominence. Yet Park finds that “the numerical majority of climate-induced refugees are likely to be those who do not have the wherewithal to make it to an international border.” (p 141) As time goes on and the financial inequities of global heating increase, it may be true that even fewer refugees have the means to get to another country: “recent studies find that gradually rising temperatures may actually reduce the rate of migration in many poorer countries.” (p 141)

Slow Burn is weak on the issue of multiple compounding factors as they will interact over several decades. It’s one thing to measure current heat-mortality rates, but quite another to project that these rates will rise linearly with temperatures 30 or 60 years from now. Suppose, as seems plausible, that a steep rise in 30°C or hotter days is accompanied by reduced food supplies due to lower yields, higher basic food prices, increased severe storms that destroy or damage many homes, and less reliable electricity grids due to storms and periods of high demand. Wouldn’t we expect, then, that the 73-per-100,000-people annual heat-related deaths estimated by the Climate Impact Lab would be a serious underestimate?

Park also writes that due to rising incomes, “most places will be significantly better able to deal with climate change in the future.” (p 229) As for efforts at reducing emissions, in Park’s opinion “it seems reasonable to suppose that thanks in part to pledged and actual emissions cuts achieved in the past few decades, the likelihood of truly disastrous warming may have declined nontrivially.” (p 218) If you don’t share his faith in economic growth, and if you lack confidence that pledged emissions cuts will be made actual, some paragraphs in Slow Burn will come across as wishful thinking.

Yet on the book’s two primary themes – that climate change is already causing major and documentable harms to populations around the world, and that climate justice concerns must be at the forefront of adaptation efforts – Park marshalls strong evidence to present a compelling case.

Reckoning with ‘the battering ram of the Anthropocene’

Also posted on Resilience

Is the word right on the tip of your tongue? You know, the word that sums up the ecological effects of more, faster and bigger vehicles, driving along more and wider lanes of roadway, throughout your region and all over the world?

If the word “traffication” comes readily to mind, then you are likely familiar with the work of British scientist Paul Donald. After decades spent studying the decline of many animal species, he realized he – and we – need a simple term summarizing the manifold ways that road traffic impacts natural systems. So he invented the word which serves as the title of his important new book Traffication: How Cars Destroy Nature and What We Can Do About It.

The field of study now known as road ecology got its start in 1925, when Lillian and Dayton Stoner decided to count and categorize the road kill they observed on an auto trip in the US Midwest. The science of road ecology has grown dramatically, especially in the last 30 years. Many road ecologists today recognize that road kill is not the only, and likely not even the most damaging, effect of the steady increase in traffication.

Noise pollution, air and water pollution, and light pollution from cars have now been documented to cause widespread health problems for amphibians, fish, mammals and birds. These effects of traffication spread out far beyond the actual roadways, though the size of “road effect zones” vary widely depending on the species being studied.

Donald is based in the United Kingdom, but he notes there are relatively few studies in road ecology in the UK; far more studies have been done in the US, Canada, and Western Europe. In summarizing this research Donald makes it clear that insights gained from road ecology should get much more attention from conservation biologists, transport planners, and those writing and responding to environmental impact assessments.

While in no way minimizing the impacts of other threats to biodiversity – agricultural intensification and climate change, to name two – the evidence for traffication as a major threat is just as extensive, Donald writes. He cites an apt metaphor coined by author Bryan Appleyard: the car is “the Anthropocene’s battering ram”.

Traffication has important implications for every country under the spell of the automobile – and particular relevance to a controversy in my own region of Ontario, Canada.

A slow but relentless increase

One reason traffication has been understudied, Donald speculates, is that it has crept up on us.

“These increases have been so gradual, a rise in traffic volume of 1 or 2 per cent each year, that most of us have barely noticed them, but the cumulative effect across a human lifetime has been profound.” … (All quotes in this article from the digital version of Traffication.)

“Since the launch of the first Space Shuttle and the introduction of the mobile phone in the early 1980s,” Donald adds, “the volume of traffic on our roads has more than doubled.”

Though on a national or global scale the increase in traffic has been gradual, in some localities traffication, with all its ill effects, can suddenly accelerate.

That will be the case if the government of Ontario follows through with its plan to rapidly urbanize a rural area on the eastern flank of the new Rouge National Urban Park (RNUP), which in turn is on the eastern flank of Toronto.

The area now slated for housing tracts was, until last November, protected by Greenbelt legislation as farmland, wetland and woodland. That suddenly changed when Premier Doug Ford announced the land is to be the site of 30,000 new houses in new car-dependent suburbs.1 And barring a miracle, the new housing tracts will be car-dependent since the land is distant from employment areas and services, distant from major public transit, and because the Provincial government places far more priority on building new highways than building new transit.

Though the government has made vague promises to protect woodlands and wetlands dotted between the housing tracts, these tiny “nature preserves” would be hemmed in on all sides by new, or newly busy, roads.

As I read through Donald’s catalog of the harms caused by traffication, I thought of the ecological damage that will be caused if traffic suddenly increases exponentially in this area that is home to dozens of threatened species. The same effects are already happening in countless heavily trafficated locales around the world.

“A shattered soundscape”

Donald summarizes the wide array of health problems documented in people who live with constant traffic noise. The effects on animals are no less wide-ranging:

“A huge amount of research, from both the field and the laboratory, has shown that animals exposed to vehicle noise suffer higher stress levels and weakened immune systems, leading to disrupted sleep patterns and a drop in cognitive performance.”

Among birds, he write, “even low levels of traffic noise results in a drop in the number of eggs laid and the health of the chicks that hatch.” As a result, “Birds raised in the presence of traffic noise are prematurely aged, and their future lifespans already curtailed, before they have even left the nest.”

Disruptions in the natural soundscape are particularly stress-inducing to prey species (and most species, even predators, are at risk of being someone else’s prey), since they have difficulty hearing the alarm signals sent out by members of their own and other species. To compensate, Donald writes, “animals living near roads become more vigilant, spending more of their time looking around for danger and consequently having less time to feed.”

A few species are tolerant of high noise levels, and seldom become road kill; their numbers tend to go up as a result of traffication. Many more species are bothered by the noise, even at a distance of several hundred meters from a busy road. That means their good habitat continues to shrink and and their numbers continue to drop. Donald writes that half of the area of the United Kingdom, and three-quarters of the area of England, is within 500 meters of a road, and therefore within the zone where noise pollution drives away or sickens many species.

Six-hundred thousand islands

When coming up to a roadway, Donald explains, some animals pay no attention at all, others pause and then dash across, while others seldom or never cross the road. As the road gets wider, or as the traffic gets faster and louder, more and more species become road avoiders.

While the road avoiders do not end up as roadkill, the road’s effect on the long-term prospects of their species is still negative.

When animals – be they insects, amphibians, mammals or birds – refuse to cross the roads that surround their territories, they are effectively marooned on islands. Taking account of major roads only, the land area of the globe is now divided into 600,000 such islands, Donald writes.

Populations confined to small islands gradually become less genetically diverse, which makes them less resilient to diseases, stresses and catastrophes. Local floods, fires, droughts, or heat waves might wipe out a species within such an island – and the population is not likely to be replenished from another island if the barriers (roadways) are too wide or too busy.

The onset of climate change adds another dimension to the harm:

“For a species to keep up as its climate bubble moves across the landscape , it needs to be able to spread into new areas as they become favourable . … In an era of rapid climate change, wildlife needs landscapes to be permeable, allowing each species to adapt to changing conditions in the optimal way. For many species, and particularly for road-avoiders, our dense network of tarmac [paved road] blockades will prove to be a significant problem.”

Escaping traffication

Is traffication a one-way road, destined to get steadily worse each year?

There are solutions, Donald writes, though they require significant changes from society. He makes clear that electrification of the auto fleet is not one of those solutions. It’s obvious that electric cars will not reduce the numbers of animals sacrificed as road kill. Less obvious, perhaps, is that electric cars will make little difference to the noise pollution, light pollution, and local air pollution resulting from traffication.

At speeds over about 20 mph (32 km/hr) most car noise comes from the sound of tires on pavement, so electric cars remain noisy at speed.

And due to concerted efforts to reduce the tailpipe emissions from gas-powered cars, most particulate emissions from cars are now due to tire wear and brake pad wear. Since electric cars are generally heavier, their non-tailpipe emissions tend to be worse than those from gas-powered cars.

One remedy that has been implemented with great success is the provision of wildlife bridges or tunnels across major roadways. In combination with fencing, such crossings have been found to reduce road kill by more than 80 per cent. The crossings are expensive, however, and do nothing to remedy the effects of noise, particulate pollution, and light pollution.

A partial but significant remedy can be achieved wherever there is a concerted program of auto speed reductions:

“Pretty much all the damage caused by road traffic – to the environment, to wildlife and to our health – increases exponentially with vehicle speed. The key word here is exponentially – a drop in speed of a mere 10 mph might halve some of the problems of traffication, such as road noise and particulate pollution.”

Beyond those remedies, though, the key is social reorganization that results in fewer people routinely driving cars, and then for shorter distances. Such changes will take time – but at least in some areas of global society, such changes are beginning.

Donald finds cause for cautious optimism, he says, in that “society is already drifting slowly towards de-traffication, blown by strengthening winds of concern over human health and climate change.”

There’s scant evidence of this trend in my part of Ontario right now,2 but Donald believes “We might at least be approaching the high water mark of motoring, what some writers refer to as ‘ peak car ’”. Let’s hope he’s right.


1 A scathing report by the Province’s Auditor General found that the zoning change will result in a multi-billion dollar boost to the balance sheets of large land speculators, who also happen to be friends of and donors to the Premier.

2 However, there has been a huge groundswell of protest against Premier Doug Ford’s plan to open up Greenbelt lands for car-dependent suburban sprawl, and it remains unclear if the plan will actually become reality. See Stop Sprawl Durham for more information.


Note to subscribers: the long gap between posts this summer has been due to retina surgery and ensuing complications. It’s too early to tell if I’ll be able to resume and maintain a regular posting schedule, but I do hope to complete a post on transforming car-dependent neighbourhoods as promised in May.

How parking ate North American cities

Also published on Resilience

Forty-odd years ago when I moved from a small village to a big city, I got a lesson in urbanism from a cat who loved to roam. Navigating the streets late at night, he moved mostly under parked cars or in their shadows, intently watching and listening before quickly crossing an open lane of pavement. Parked cars helped him avoid many frightening hazards, including the horrible danger of cars that weren’t parked.

The lesson I learned was simple but naïve: the only good car is a parked car.

Yet as Henry Grabar’s new book makes abundantly clear, parking is far from a benign side-effect of car culture.

The consequences of car parking include the atrophy of many inner-city communities; a crisis of affordable housing; environmental damages including but not limited to greenhouse gas emissions; and the continued incentivization of suburban sprawl.

Paved Paradise is published by Penguin Random House, May 9, 2023

Grabar’s book is titled Paved Paradise: How Parking Explains the World. The subtitle is slightly hyperbolic, but Grabar writes that “I have been reporting on cities for more than a decade, and I have never seen another subject that is simultaneously so integral to the way things work and so overlooked.”

He illustrates his theme with stories from across the US, from New York to Los Angeles, from Chicago to Charlotte to Corvallis.

Paved Paradise is as entertaining as it is enlightening, and it should help ensure that parking starts to get the attention it deserves.

Consider these data points:

  • “By square footage, there is more housing for each car in the United States than there is housing for each person.” (page 71; all quotes in this article are from Paved Paradise)
  • “The parking scholar Todd Litman estimates it costs $4,400 to supply parking for each vehicle for a year, with drivers directly contributing just 20 percent of that – mostly in the form of mortgage payments on a home garage.” (p 81)
  • “Many American downtowns, such as Little Rock, Newport News, Buffalo, and Topeka, have more land devoted to parking than to buildings.” (p 75)
  • Parking scholar Donald Shoup estimated that in 1998, “there existed $12,000 in parking for every one of the country’s 208 million cars. Because of depreciation, the average value of each of those vehicles was just $5,500 …. Therefore, Shoup concluded, the parking stock cost twice as much as the actual vehicles themselves. (p 150)

How did American cities come to devote vast amounts of valuable real estate to car storage? Grabar goes back to basics: “Every trip must begin and end with a parking space ….” A driver needs a parking space at home, and another one at work, another one at the grocery store, and another one at the movie theatre. There are six times as many parking spaces in the US as there are cars, and the multiple is much higher in some cities.

This isn’t a crippling problem in sparsely populated areas – but most Americans live or work or shop in relatively crowded areas. As cars became the dominant mode of transportation the “parking problem” became an obsession. It took another 60 or 70 years for many urban planners to reluctantly conclude that the parking problem can not be solved by building more parking spaces.

By the dawn of the twenty-first century parking had eaten American cities. (And though Grabar limits his story to the US, parking has eaten Canadian cities too.)

Grabar found that “Just one in five cities zoned for parking in 1950. By 1970, 95 percent of U.S. cities with over twenty-five thousand people had made the parking spot as legally indispensable as the front door.” (p 69)

The Institute of Transportation Engineers theorized that every building “generated traffic”, and therefore every type of building should be required to provide at least a specified number of parking spaces. So-called “parking minimums” became a standard feature of the urban planning rulebook, with wide-ranging and long-lasting consequences.

Previously common building types could no longer be built in most areas of most American cities:

“Parking requirements helped trigger an extinction-level event for bite-size, infill apartment buildings …; the production of buildings with two to four units fell more than 90 percent between 1971 and 2021.” (p 180)

On a small lot, even if a duplex or quadplex was theoretically permitted, the required parking would eat up too much space or require the construction of unaffordable underground parking.

Commercial construction, too, was inexorably bent to the will of the parking god:

“Fast-food architecture – low-slung, compact structures on huge lots – is really the architecture of parking requirements. Buildings that repel each other like magnets of the same pole.” (p 181)

While suburban development was subsidized through vast expenditures on highways and multi-lane arterial roads, parking minimums were hollowing out urban cores. New retail developments and office complexes moved to urban edges where big tracts of land could be affordably devoted to “free” parking.

Coupled with separated land use rules – keeping workplaces away from residential or retail areas – parking minimums resulted in sprawling development. Fewer Americans lived within safe walking or cycling distance from work, school or stores. Since few people had a good alternative to driving, there needed to be lots of parking. Since new developments needed lots of extra land for that parking, they had to be built further apart – making people even more car-dependent.

As Grabar explains, the almost universal application of parking minimums does not indicate that there is no market for real estate with little or no parking. To the contrary, the combination of high demand and minimal supply means that neighbourhoods offering escape from car-dependency are priced out of reach of most Americans:

“The most expensive places to live in the country were, by and large, densely populated and walkable neighborhoods. If the market was sending a signal for more of anything, it was that.” (p 281)

Is the solution the elimination of minimum parking requirements? In some cases that has succeeded – but reversing a 70- or 80-year-old development pattern has proven more difficult in other areas.

The high cost of free parking

Paved Paradise acknowledges an enormous debt to the work of UCLA professor Donald Shoup. Published in 2005, Shoup’s 773-page book The High Cost of Free Parking continues to make waves.

As Grabar explains, Shoup “rode his bicycle to work each day through the streets of Los Angeles,” and he “had the cutting perspective of an anthropologist in a foreign land.” (p 149)

While Americans get exercised about the high price they occasionally pay for parking, in fact most people park most of the time for “free.” Their parking space is paid for by tax dollars, or by store owners, or by landlords. Most of the cost of parking is shared between those who drive all the time and those who seldom or never use a car.

By Shoup’s calculations, “the annual American subsidy to parking was in the hundreds of billions of dollars.” Whether or not you had a car,

“You paid [for the parking subsidy] in the rent, in the check at the restaurant, in the collection box at church. It was hidden on your receipt from Foot Locker and buried in your local tax bill. You paid for parking with every breath of dirty air, in the flood damage from the rain that ran off the fields of asphalt, in the higher electricity bills from running an air conditioner through the urban heat-island effect, in the vanishing natural land on the outskirts of the city. But you almost never paid for it when you parked your car ….” (p 150)

Shoup’s book hit a nerve. Soon passionate “Shoupistas” were addressing city councils across the country. Some cities moved toward charging market prices for the valuable public real estate devoted to private car storage. Many cities also started to remove parking minimums from zoning codes, and some cities established parking maximums – upper limits on the number of parking spaces a developer was allowed to build.

In some cases the removal of parking minimums has had immediate positive effects. Los Angeles became a pioneer in doing away with parking minimums. A 2010 survey looked at downtown LA projects constructed following the removal of parking requirements. Without exception, Grabar writes, these projects “had constructed fewer parking spaces than would have been required by [the old] law. Developers built what buyers and renters wanted ….” (p 193) Projects which simply wouldn’t have been built under old parking rules came to market, offering buyers and tenants a range of more affordable options.

In other cities, though, the long habit of car-dependency was more tenacious. Grabar writes:

“Starting around 2015, parking minimums began to fall in city after city. But for every downtown LA, where parking-free architecture burst forth, there was another place where changing the law hadn’t changed much at all.” (p 213)

In neighbourhoods with few stores or employment prospects within a walking or cycling radius, and in cities with poor public transit, there remains a weak market for buildings with little or no parking. After generations of heavily subsidized, zoning-incentivized car-dependency,

“There were only so many American neighborhoods that even had the bones to support a car-free life …. Parking minimums were not the only thing standing between the status quo and the revival of vibrant, walkable cities.” (p 214)

There are many strands to car culture: streets that are unsafe for people outside a heavy armoured box; an acute shortage of affordable housing except at the far edges of cities; public transit that is non-existent or so infrequent that it can’t compete with driving; residential neighbourhoods that fail to provide work, shopping, or education opportunities close by. All of these factors, along with the historical provision of heavily subsidized parking, must be changed in tandem if we want safe, affordable, environmentally sustainable cities.

Though it is an exaggeration to say “parking explains the world”, Grabar makes it clear that you can’t explain the world of American cities without looking at parking.

In the meantime, sometimes it works to use parked cars to promote car-free ways of getting around. Grabar writes,

“One of [Janette] Sadik-Khan’s first steps as transportation commissioner was taking a trip to Copenhagen, where she borrowed an idea for New York: use the parked cars to protect the bike riders. By putting the bike lanes between the sidewalk and the parking lane, you had an instant wall between cyclists and speeding traffic. Cycling boomed; injuries fell ….” (p 256)

A street-wise cat I knew forty years ago would have understood.

What we know, and don’t know, about bees

Also published on Resilience

It will be several more weeks before bees start visiting flowers in my part of the world. But while I wait for gardens and meadows to come alive again, it’s been a joy to read Stephen Buchmann’s new book What a Bee Knows. (Island Press, March 2023)

Buchmann sets the scene in his opening chapter, describing how a ground-nesting bee cautiously emerges from her nest after looking and listening for possible predators:

“The female bee briefly shivers the powerful flight muscles within her thorax to warm up. Ready, she launches herself skyward and hovers in midair. Performing an aerial pirouette, she flies left, then back to the center, and then to the right of her nest. She repeats these back-and-forth, ever-wider zigzags, all while facing her nest and flying higher with each pass. In fact, she is memorizing the locations of the physical landmarks around her nest. These could be small stones, live or dead plants, bits of wood, or similar debris. She quickly creates a mental map of her home terrain. In less than a minute, she has memorized all the visual imagery, the spatial geometry, and the smells of her immediate surroundings.” (What a Bee Knows: Exploring the Thoughts, Memories, and Personalities of Bees, page 2)

Bees use a wide range of senses to navigate through the world, sometimes in ways we can scarcely imagine. As a pollination ecologist with decades of research experience, Buchmann is an ideal guide to this world, at once both familiar and alien, in our own backyards.

Let’s start with that word “knows”. Buchmann cites his own experience and the work of many other researchers to make the case that bees form, memorize, and use mental maps; they can count; they feel pain; they can react to changes by enacting new plans, even when the plans will not bear fruit for most of a bee’s lifetime; and they can likely pass some cognitive tests that are beyond the ability of dogs and cats. All very impressive, for a group of insects whose tiny brains have hardly changed in structure for a hundred million years.

That brain must manage a range of sensory inputs. A bee’s eyes – far larger, proportionally, than ours – see in three colours, ultraviolet, green and blue. In some respects a bee’s vision is low-resolution, but it provides high-speed imagery which allows a bee to distinguish flowers, and other insects, while zooming through meadows at 20 kilometers/hour or faster.

Honey Bee at Borage flower. Buchmann writes: “Compared with the size of their heads, bee have immense faceted eyes. Their vision, however, is much coarser than our own; they can recognize the shape of a flower only from a few inches away. Bee color vision is shifted into the ultraviolet (UV) part of the spectrum, but they are blind to red colors. Astonishingly, they can recognized patterns of polarized light across an otherwise uniform blue sky.” (What a Bee Knows, p 47)

Nearly all species of bees are vegans, though they evolved from predatory wasps. These wasps dined on tiny thrips, which tended to come with a tasty dusting of nutritious pollen. Over time, the prevailing theory goes, proto-bees learned to stop chasing thrips and just go straight to flowers for meals of pollen and nectar. Today bees attach a tiny ball of “bee bread” – a mix of nectar and pollen – to each egg, and this supplies all the nutrients a hatching larva needs to develop into an adult flying bee.

Though most flowering plants need bees and/or other pollinators, and bees need flowers, the relationship is complex.

Bee laden with Yellow Salsify pollen. Buchmann writes: “we need to remember that plants and bees have very different evolutionary goals. Bees must collect pollen and nectar to feed their larvae and themselves. … Flowering plants want to minimize pollen wastage.” (p 77)

Flowers need to ensure someone will carry pollen from one flower to another of the same species. That service comes with costs:

“About 3 percent of a flowering plant’s total energy budget is invested in the production of nectar. Pollen, floral oils, resins, and floral scent molecules are even more costly for plants to produce in their strategies for attracting, keeping, and rewarding pollinating bees.” (p 86)

Bees will happily move from flower to flower, picking up and losing pollen along the way. But if a bee takes pollen from a salsify flower, visits a fleabane next, then goes to a dandelion, not many of the pollen grains will make it to the right blossoms to fertilize those flowers. From a flower’s point of view, it’s important that a bee visits mostly flowers of one species on a given day.

Bumblebee on catnip. Buchmann writes: “[Researchers found that] bumblebees had an intermediate level of floral constancy. Bumblebees are considered to be less faithful foragers than honey bees.” (p 137)

Richly attractive scents help flowers keep bees coming back. But how does the bee detect that scent? More to the point, where is a bee’s nose? Buchmann tells us:

“The honey bee’s paired antennae are her nose. Both antennae are covered with thousands of sensory hairs, most of which respond to airborne odors. … Bees’ antennae … provide directional information. Think of smelling in stereo. Their antennae can move independently; therefore, unlike us with our fixed noses, bees can get a three-dimensional impression of an odor field.” (p 59-60)

But if flowers smell so good they keep bees coming back to their species, and only their species, that brings up another problem for bees to solve. How can a bee ensure, before she zooms in for a landing, that another bee hasn’t recently made off with all the pollen?

The answer may be that bees, which pick up a positive electrostatic charge while flying, are able to sense changes in the electrostatic charges of flowers – allowing them to sense which flowers have been recently visited.

Honey Bee on Aster. Buchmann writes: “Plants typically bear flowers at or near their growing tips, and these tips develop the strongest negative charges over an entire plant’s surface. Positively charged flying bumblebees and likely other bees can detect the negative charges on flower surfaces. Across their petals, stamens, and styles, flowers possess fine patterns of differing electrostatic charges.” (p 68)

What a Bee Knows is stuffed with fascinating information. Why does a male bee (drone) have no father, though he does have a grandfather? (It’s because a queen bee lays some fertilized eggs and some unfertilized eggs. All male bees are born from the unfertilized eggs, while all female bees, including queens, are born from fertilized eggs.)

How do honey bees make precisely-engineered, energy- and material-efficient honeycomb cells from beeswax? (Partly through careful teamwork in producing, chewing, and depositing tiny flakes of wax – and partly through the emergent, self-organizing physical properties of beeswax when it is heated to a range of  37°–40°C.)

We might guess that for a scientist with a career in bee research, one of the most satisfying recurring phrases in the book is “we don’t know” – many mysteries remain for bee students to explore. I wish, though, that the book were not so wholly reliant solely on the western scientific tradition, or at least that it had clearly acknowledged that many peoples around the world have likely known things about bees long before any western-trained scientist “discovered” these things. Indeed, much knowledge about bees has likely vanished in recent centuries, along with the traditions and languages of many human cultures.

One other question kept coming to my mind as I read through the book: what about the widely-reported problem of diminishing pollinator populations, which I can see even in my own back yard? As Buchmann reveals in the Epilogue, he too has been concerned about this problem – for decades. In 1996 he co-authored a book entitled The Forgotten Pollinators, and in past twenty-seven years, “unfortunately, things have only gotten worse for pollinators.” (p 211)

For 100 million years, bees and their relatives have made the most of their marvelously capable sensory organs, and a relatively simple, efficient brain. They have adapted to changes in ecosystems while also engineering changes in those ecosystems.

The great majority of flowering plants, including those responsible for most human food, depend on bees and other pollinators – but by our actions we are rapidly killing them off.

As Buchmann puts it, “It’s simple: we need bees more than they need us.”

Will some species of bees find ways to survive, either in spite of us or after we are gone? Will we humans carry on with the practices that are driving so many species towards extinction, thereby promoting, also, our own extinction? The answer to those questions, too, is simple.

We don’t know.

A road map that misses some turns

A review of No Miracles Needed

Also published on Resilience

Mark Jacobson’s new book, greeted with hosannas by some leading environmentalists, is full of good ideas – but the whole is less than the sum of its parts.

No Miracles Needed, by Mark Z. Jacobson, published by Cambridge University Press, Feb 2023. 437 pages.

The book is No Miracles Needed: How Today’s Technology Can Save Our Climate and Clean Our Air (Cambridge University Press, Feb 2023).

Jacobson’s argument is both simple and sweeping: We can transition our entire global economy to renewable energy sources, using existing technologies, fast enough to reduce annual carbon dioxide emissions at least 80% by 2030, and 100% by 2050. Furthermore, we can do all this while avoiding any major economic disruption such as a drop in annual GDP growth, a rise in unemployment, or any drop in creature comforts. But wait – there’s more! In so doing, we will also completely eliminate pollution.

Just don’t tell Jacobson that this future sounds miraculous.

The energy transition technologies we need – based on Wind, Water and Solar power, abbreviated to WWS – are already commercially available, Jacobson insists. He contrasts the technologies he favors with “miracle technologies” such as geoengineering, Carbon Capture Storage and Utilization (CCUS), or Direct Air Capture of carbon dioxide (DAC). These latter technologies, he argues, are unneeded, unproven, expensive, and will take far too long to implement at scale; we shouldn’t waste our time on such schemes.  

The final chapter helps to understand both the hits and misses of the previous chapters. In “My Journey”, a teenage Jacobson visits the smog-cloaked cities of southern California and quickly becomes aware of the damaging health effects of air pollution:

“I decided then and there, that when I grew up, I wanted to understand and try to solve this avoidable air pollution problem, which affects so many people. I knew what I wanted to do for my career.” (No Miracles Needed, page 342)

His early academic work focused on the damages of air pollution to human health. Over time, he realized that the problem of global warming emissions was closely related. The increasingly sophisticated computer models he developed were designed to elucidate the interplay between greenhouse gas emissions, and the particulate emissions from combustion that cause so much sickness and death.

These modeling efforts won increasing recognition and attracted a range of expert collaborators. Over the past 20 years, Jacobson’s work moved beyond academia into political advocacy. “My Journey” describes the growth of an organization capable of developing detailed energy transition plans for presentation to US governors, senators, and CEOs of major tech companies. Eventually that led to Jacobson’s publication of transition road maps for states, countries, and the globe – road maps that have been widely praised and widely criticized.

In my reading, Jacobson’s personal journey casts light on key features of No Miracles Needed in two ways. First, there is a singular focus on air pollution, to the omission or dismissal of other types of pollution. Second, it’s not likely Jacobson would have received repeat audiences with leading politicians and business people if he challenged the mainstream orthodox view that GDP can and must continue to grow.

Jacobson’s road map, then, is based on the assumption that all consumer products and services will continue to be produced in steadily growing quantities – but they’ll all be WWS based.

Does he prove that a rapid transition is a realistic scenario? Not in this book.

Hits and misses

Jacobson gives us brief but marvelously lucid descriptions of many WWS generating technologies, plus storage technologies that will smooth the intermittent supply of wind- and sun-based energy. He also goes into considerable detail about the chemistry of solar panels, the physics of electricity generation, and the amount of energy loss associated with each type of storage and transmission.

These sections are aimed at a lay readership and they succeed admirably. There is more background detail, however, than is needed to explain the book’s central thesis.

The transition road map, on the other hand, is not explained in much detail. There are many references to scientific papers in which he outlines his road maps. A reader of No Miracles Needed can take Jacobson’s word that the model is a suitable representation, or you can find and read Jacobson’s articles in academic journals – but you don’t get the needed details in this book.

Jacobson explains why, at the level of a device such as a car or a heat pump, electric energy is far more efficient in producing motion or heat than is an internal combustion engine or a gas furnace. Less convincingly, he argues that electric technologies are far more energy-efficient than combustion for the production of industrial heat – while nevertheless conceding that some WWS technologies needed for industrial heat are, at best, in prototype stages.

Yet Jacobson expresses serene confidence that hard-to-electrify technologies, including some industrial processes and long-haul aviation, will be successfully transitioning to WWS processes – perhaps including green hydrogen fuel cells, but not hydrogen combustion – by 2035.

The confidence in complex global projections is often jarring. For example, Jacobson tells us repeatedly that the fully WWS energy system of 2050 “reduces end-use energy requirements by 56.4 percent” (page 271, 275).1 The expressed precision notwithstanding, nobody yet knows the precise mix of storage types, generation types, and transmission types, which have various degrees of energy efficiency, that will constitute a future WWS global system. What we should take from Jacobson’s statements is that, based on the subset of factors and assumptions – from an almost infinitely complex global energy ecosystem – which Jacobson has included in his model, the calculated outcome is a 56% end-use energy reduction.

Also jarring is the almost total disregard of any type of pollution other than that which comes from fossil fuel combustion. Jacobson does briefly mention the particles that grind off the tires of all vehicles, including typically heavier EVs. But rather than concede that these particles are toxic and can harm human and ecosystem health, he merely notes that the relatively large particles “do not penetrate so deep into people’s lungs as combustion particles do.” (page 49)

He claims, without elaboration, that “Environmental damage due to lithium mining can be averted almost entirely.” (page 64) Near the end of the book, he states that “In a 2050 100 percent WWS world, WWS energy private costs equal WWS energy social costs because WWS eliminates all health and climate costs associated with energy.” (page 311; emphasis mine)

In a culture which holds continual economic growth to be sacred, it would be convenient to believe that business-as-usual can continue through 2050, with the only change required being a switch to WWS energy.

Imagine, then, that climate-changing emissions were the only critical flaw in the global economic system. Given that assumption, is Jacobson’s timetable for transition plausible?

No. First, Jacobson proposes that “by 2022”, no new power plants be built that use coal, methane, oil or biomass combustion; and that all new appliances for heating, drying and cooking in the residential and commercial sectors “should be powered by electricity, direct heat, and/or district heating.” (page 319) That deadline has passed, and products that rely on combustion continue to be made and sold. It is a mystery why Jacobson or his editors would retain a 2022 transition deadline in a book slated for publication in 2023.

Other sections of the timeline also strain credulity. “By 2023”, the timeline says, all new vehicles in the following categories should be either electric or hydrogen fuel-cell: rail locomotives, buses, nonroad vehicles for construction and agriculture, and light-duty on-road vehicles. This is now possible only in a purely theoretical sense. Batteries adequate for powering heavy-duty locomotives and tractors are not yet in production. Even if they were in production, and that production could be scaled up within a year, the charging infrastructure needed to quickly recharge massive tractor batteries could not be installed, almost overnight, at large farms or remote construction sites around the world.

While electric cars, pick-ups and vans now roll off assembly lines, the global auto industry is not even close to being ready to switch the entire product lineup to EV only. Unless, of course, they were to cut back auto production by 75% or more until production of EV motors, batteries, and charging equipment can scale up. Whether you think that’s a frightening prospect or a great idea, a drastic shrinkage in the auto industry would be a dramatic departure from a business-as-usual scenario.

What’s the harm, though, if Jacobson’s ambitious timeline is merely pushed back by two or three years?

If we were having this discussion in 2000 or 2010, pushing back the timeline by a few years would not be as consequential. But as Jacobson explains effectively in his outline of the climate crisis, we now need both drastic and immediate actions to keep cumulative carbon emissions low enough to avoid global climate catastrophe. His timeline is constructed with the goal of reducing carbon emissions by 80% by 2030, not because those are nice round figures, but because he (and many others) calculate that reductions of that scale and rapidity are truly needed. Even one or two more years of emissions at current rates may make the 1.5°C warming limit an impossible dream.

The picture is further complicated by a factor Jacobson mentions only in passing. He writes,

“During the transition, fossil fuels, bioenergy, and existing WWS technologies are needed to produce the new WWS infrastructure. … [A]s the fraction of WWS energy increases, conventional energy generation used to produce WWS infrastructure decreases, ultimately to zero. … In sum, the time-dependent transition to WWS infrastructure may result in a temporary increase in emissions before such emissions are eliminated.” (page 321; emphasis mine)

Others have explained this “temporary increase in emissions” at greater length. Assuming, as Jacobson does, that a “business-as-usual” economy keeps growing, the vast majority of goods and services will continue, in the short term, to be produced and/or operated using fossil fuels. If we embark on an intensive, global-scale, rapid build-out of WWS infrastructures at the same time, a substantial increment in fossil fuels will be needed to power all the additional mines, smelters, factories, container ships, trucks and cranes which build and install the myriad elements of a new energy infrastructure. If all goes well, that new energy infrastructure will eventually be large enough to power its own further growth, as well as to power production of all other goods and services that now rely on fossil energy.

Unless we accept a substantial decrease in non-transition-related industrial activity, however, the road that takes us to a full WWS destination must route us through a period of increased fossil fuel use and increased greenhouse gas emissions.

It would be great if Jacobson modeled this increase to give us some guidance how big this emissions bump might be, how long it might last, and therefore how important it might be to cumulative atmospheric carbon concentrations. There is no suggestion in this book that he has done that modeling. What should be clear, however, is that any bump in emissions at this late date increases the danger of moving past a climate tipping point – and this danger increases dramatically with every passing year.


1In a tl;dr version of No Miracles Needed published recently in The Guardian, Jacobson says “Worldwide, in fact, the energy that people use goes down by over 56% with a WWS system.” (“‘No miracles needed’: Prof Mark Jacobson on how wind, sun and water can power the world”, 23 January 2023)
