Quiet and Close Observation: The Forest Unseen by David George Haskell

The Forest Unseen is a 2012 book by David George Haskell which I have only now gotten around to reading. This blog is your place to go for reviews of old books. Of course, maybe it is new to you, in which case I hope this review encourages you to read the book.

Haskell chose a square meter of area on the floor of an old growth forest in Tennessee. It was not out in the middle of a wilderness; there is no such place in the eastern United States. In fact, it was just downhill from a golf course. But it was as close to undisturbed nature as one could expect to find. Having chosen his spot, Haskell watched it for a year and wrote a book about what he saw.

Anybody could have done what Haskell did. It is true that he used his immense knowledge of nature to not only identify the organisms that he saw, but to draw the numerous connections between these organisms and the larger world of science. But anybody could have seen these things and figured out at least a little about what they were doing. That is the main impact of The Forest Unseen: wonders await us if we just sit quietly and look closely at the natural world. You don’t need a Ph.D. to do this.

The tiny world of fungi and arthropods and wildflowers is an exciting place. Haskell captures the immediacy of this excitement by usually writing in the present tense. You are there with him, seeing what he sees. You can’t just quickly glance at the world of nature. There is a photo on the cover of Haskell looking through a hand lens at the forest floor. Much of the excitement is on a tiny scale. At one point, he had to watch the soil for a half hour before he realized that what he was seeing was a horsehair worm rather than a bit of leaf litter.

Haskell used poetic language masterfully. As numerous reviewers have remarked, his descriptions are some of the most beautiful that have been written. For example, he described chickadees on a cold day as “four pennyweight furnaces” because of the immense amount of heat, relative to their size, that they produce. He referred to the “pheromone love poems” of invertebrates. Tiny mushrooms and other fungi are a “regatta” (he also says “flotilla”) of colors in a decomposing sea of leaf litter. He is the only writer I know, other than Edgar Allan Poe, to use the word tintinnabulation. This poetic language is exactly what his readers, amateur naturalists, need. Scientists would strongly object to some of his terms, for example when he called a fern gametophyte a little lily pad. It looks like one, but the description is misleading—but only misleading if you are taking a botany course. Maybe the university publishers rejected it for this reason. But the major commercial publisher that released it knew that this book was perfect for nature-lovers.

Haskell draws many fascinating connections between what he sees and the larger world of scientific (and other) knowledge. For example, when he describes a snowflake, he explains how the six-sided shape follows inevitably from the chemical characteristics of the water molecules, but also that each snowflake is different because its shape is determined by so many microscale processes, the little tiny differences in temperature, humidity, and wind as each snowflake forms. Thus each snowflake is the product of natural law and historical accident. This is a major scientific concept, but you can see it in a snowflake. He also explained that Johannes Kepler, in his study of snowflakes, drew some incorrect conclusions, but his observations laid the groundwork for scientists a few decades later to discover that everything was made of atoms—something Kepler did not believe.

Haskell even discusses theology when he describes ichneumon wasps, which he saw following a sunfleck on the forest floor. These wasps lay eggs in caterpillars. The eggs hatch, and the grubs eat the caterpillars from the inside. In the nineteenth century, scientists, philosophers, and theologians argued about whether this constituted cruelty that was contrary to the character of the creator God. I’ll bet that very few of Haskell’s readers knew anything about this controversy that directly involved Charles Darwin and his religious friend, the botanist Asa Gray. Wonderful!

I hope that this book continues to inspire all of us, even after we have finished reading it. I sat outside, reading it, and my two-and-a-half-year-old granddaughter saw the picture on the cover. I told her what Haskell was doing, and right away we got out a magnifying glass and started looking closely at the soil of our backyard. It is possible that this little act, especially if we continue to do it, will have changed by granddaughter’s life.

Richard Louv’s books encourage parents to let kids play in the wild—climb trees and all that. Such undirected play is extremely important. But it is also important for people of all ages to stop and watch the immediate environment carefully and quietly, as Haskell did. It may be hard to get kids to do this for very long, but even for the few moments that they will slow down and look will prove very important to their mental development.

Alas, I cannot do what Haskell did. I cannot go and find an undisturbed place and listen to nature. I don’t believe there is any such place in Oklahoma. Every square meter of Oklahoma is filled with human noise, as well as human garbage. One “natural area” near Tulsa is right near an airport where hundreds of amateur pilots fill the sky; you can usually see and hear three at a time. Another is near a quarry which has constant explosions. There is no place where one does not continually hear loud, fast pickup trucks. Down by the Arkansas River in Tulsa, and Lake Texoma on the state’s southern border, there are hundreds of pieces of garbage everywhere. Or, perhaps there is a quiet place without trash. That is what Black Mesa is like, out in the Panhandle, very near New Mexico. But to get there I have to drive almost nine hours (one way). Not only is silent watching of nature a rare gift that Haskell has, and the rest of us could have, but places to do it are even rarer.

Garbage in Oklahoma: Another Message from Fluff


Hi. This is Fluff, a female cottonwood tree in Tulsa (she/hers). My thoughts are being passed on to you by a botanist named Stan Rice (he/him/his), who is the only human who stops to talk with me.

Right at the base of my trunk, the City of Tulsa has designated an area in which volunteers can place bags of trash. The volunteers can pick up pieces of garbage from the banks of Joe Creek, which is a drainage ditch near where I am growing, put them into plastic bags, and leave them for the city to pick up.

Joe Creek certainly needs the trash pickup. The banks of the creek are thick with garbage, most of which has floated in from upstream. Stan has estimated the number of pieces of garbage along Joe Creek. It is approximately one thousand pieces of garbage per mile. There is a similar density of garbage along the banks of the Arkansas River.

Stan has made over a hundred estimates of the number of garbage items, easily visible from an automobile, along Oklahoma highways. The number ranges from ten to a thousand, with the average being about a hundred, per mile. This means that, on a typical 200-mile drive through Oklahoma, you are likely to see twenty thousand pieces of garbage. No wonder Oklahoma has such a bad reputation, completely apart from the political news of…don’t get me started. Since Stan made so many estimates, it is not likely that bias (which I discussed in an earlier message) accounts for the results: Stan did not just see a trashy place and count the pieces of garbage. He made a systematic, unbiased survey.

Every once in a while, you will find plastic bags of garbage along the roadside in which volunteers have picked up garbage for the highway department to pick up. Once Stan even saw a man actually picking up garbage. But, from month to month and year to year, such acts seem to make very little difference in the amount of garbage along the road. The reason is the huge number of people who throw litter on the roadsides. While most people do not litter, a very large number of people do, and do so in huge amounts. One of the most common ways is that people pile light garbage in their pickup truck beds and drive along the highway, pretending to not notice that the garbage blows out of the truck bed.

And nearly all this garbage is recyclable. Not that it makes any difference right now; the City of Tulsa recycling facility is shut down due to a fire. Recyclables, put into separate bins by many conscientious homeowners, now gets mixed in with the regular garbage.

But I told Stan about another source of garbage along Joe Creek. Thieves break into houses and grab stuff to take with them. Later, they hide under the bridge and sort through it to find anything of value to them, whether it is costly items or pieces of information they can use for identity theft. They simply dump the remainder into the creek bed. Since I stand by the creek all day and all night, I have seen this happen. In addition, the homeless people gather garbage with which they construct shanties in which to live along the creek. Much of the garbage problem is also a crime problem, and a poverty problem. And a sanitation problem. It is not at all uncommon to see piles of human excrement on the path. Designating a place under a cottonwood tree for volunteers to place bags of trash will not solve these problems.

In addition, I told Stan that it is nearly inevitable that people will start bringing bags of household garbage to leave at this spot. The people who live in apartments have large dumpsters for their garbage, but these dumpsters are frequently overfilled. And then there is the stuff too big for dumpsters. Stan once saw a semi-truck fuel tank left at a recycling depot. I told Stan that the spot at the base of my trunk will quickly become a pile of junk. The location is easily accessible by truck, including pickup trucks that will bring in big pieces of junk to dump them.

The problem is that you Americans get, use, and throw away too much stuff, almost all of it in large packaging. The creek bed in my shadow is thickly studded with Styrofoam fragments. You don’t need all that stuff to be happy. Of course, what would you expect a cottonwood tree to say?

I produce a lot of leaf litter each autumn. But unlike industrial human litter, my leaves decay rapidly and help to build up the soil.

The City of Tulsa sign, beside my trunk, has been out for a couple of days and is already covered with graffiti. The city officials have good intentions, but what can they do against the mass of human filth?

There is so much garbage along the creekside path, including broken glass, that Stan doesn’t like to walk there anymore. But I hope that he comes along to say hello to me once in a while. Until next time, farewell from Fluff, the cottonwood tree.

Wonderful Diversity: The Shifting Lives of Plants

I just finished reading Jonathan Sauer’s Plant Migration: The Dynamics of Geographic Patterning in Seed Plant Species, published in 1988. In this book, the author was manifestly attempting to explain large-scale patterns and principles that governed the way in which plant species moved from one place to another. He tried to classify the different processes and kinds of habitat. He failed spectacularly. In some cases, he ended up with very, very short chapters when he found almost no examples of what should have been a general principle. The closest he came to a general law was the (trivially obvious) fact that dispersal is centrifugal (outward from a seed source) while natural selection is centripetal (getting rid of plants from places to which they have dispersed but cannot survive). Duh. He admitted that the conclusion he reached is that there are no general rules of plant migration. Each plant species has migrated during its history, and that every plant species has its own story. And he said he was pleased to have failed in his quest. I, also, am pleased. What a beautiful, diverse, quirky world this is, as illustrated by the history of each different plant species.

I enjoyed this book because I love stories. I read the Bible for its stories, not for the theological frameworks that have been imposed upon it. I read history because of its stories of unpredictable directions, not for some overarching theories.

Here are some examples from Sauer’s book that I found interesting.

  • The true cinnamon tree (Cinnamomum zeylandicum) is native to Sri Lanka (formerly Ceylon; hence the name zeylandicum) and southern India. Then why is there a patch of it in Mauritius, an island off the coast of Madagascar, about 3000 km away from Sri Lanka? A botanist might try to think of a way that cinnamon seeds might float on ocean currents and end up on Mauritius. But this is the way it actually happened. The Dutch had a monopoly on the spice trade, including cinnamon. The French wanted in on the trade, and managed to get some cinnamon plants to Mauritius, an island that they controlled. They planted some groves there. But in the face of an impending British invasion, they destroyed the garden. Too late; the birds had already spread the seeds from the garden to the surrounding forest.
  • Matricaria discoides is the little pineappleweed that grows in disturbed soils in Siberia but is also “native to” North America. Ever since I first saw this tiny plant growing in the compacted dirt of our junior high track in California, I have loved it: you can step on it, but it keeps growing. Its response to maltreatment is to release a beautiful pineapple scent. One might think that this plant was brought from Siberia to North America the same way as many other invasive plants such as Russian thistle (tumbleweed), by industrial transportation. But archaeological studies show that Matricaria was present in western North America before the arrival of Europeans. This indicates that it might have dispersed naturally or might have been carried by Native Americans when they first crossed the Bering land bridge.
  • Fennel is usually a small garden herb, but now that it has escaped from gardens into the disturbed grasslands around Santa Barbara (and on Santa Cruz island) they grow two or three meters tall and are almost the only large plants around.
  • The story of eastern Australia being taken over by Opuntia cactus from America in the early twentieth century, and their subsequent biological control, is well known to nature-lovers. What is less well known is that the Australian government blamed the spread of the cactus on emus, a large flightless native bird, eating the fruits. So, they set bounties on emus, which resulted in 335,000 emus being killed. The cactus only spread faster, up to 100 hectares per hour.
  • One of the ways that cactus spread in Australia was by the cactus pads sticking to livestock, falling off in a new location, and rooting.
  • Dam construction in the American southwest, at fever pace from the 1930s and 1960s, has led to the spread of the invasive tamarisk (salt cedar) in two ways. First, there are no longer downstream floods that would wash away the salt cedar thickets. Second, sand accumulation above the dam created new habitat for the tamarisks.

One theme that does recur over and over is that nearly all of the changes that humans have inflicted on the natural world have been disruptive. The natural world is incredibly complex, and whatever happens in one part causes a change in another part. Humans have tried to impose simplicity on a system that was never meant to have it, whether it was sheep ranches on the Santa Barbara Channel Islands or farms in the Midwest. To force nature to stay within the conceptual boundaries we have set for it is like getting a two-year-old to always do exactly what you want. Only it’s worse, because every species is like a squirming toddler. Just about the only example of humans doing something constructive was that the goats which overran Santa Catalina Island off the California coast stayed away from the resort town of Avalon, perhaps scared of the people, and this allowed the native chaparral and sage to grow back.

A major example of human interference has been fire suppression, about which I have previously written in this blog. Foresters wanted to control all wildfires but, Sauer said on page 130, they “quickly realized…that they had grabbed a tiger by the tail.” In the absence of small fires, dead wood builds up, with the result that any fires that do start will be infernos.

Another recurring theme is that colonial powers have repeatedly kicked out native peoples who were living sustainably, whether Native American or native New Caledonian people, and then impose a system unsuited to the land and which inevitably fails. Fire suppression is a good example. David Douglas, after whom the Douglas fir is named, saw Natives burning savannas in 1826.

Sauer brought part of the confusion on himself. He included migration in space, whether it was migrations of just a few meters or migrations halfway around the world. He included migration in time, whether just since the last ice age or since the beginning of plant life on dry land. The result was a mishmashed compendium of fascinating stories. But I liked it anyway. Long live diversity!

Our Continuing Shame of Racism: A View from 1964

 The days are counting down here in Tulsa for the hundredth anniversary of the Tulsa Race Massacre, which started on May 31, 1921. For many years, is event, in which white Tulsans burned to the ground the prosperous Greenwood district, in which black people created thriving businesses. It has been difficult to get very many facts about what happened, even a total count of how many were killed (mostly? all?) black, of what kinds of atrocities may or may not have been carried out. Newspaper accounts from the time vanished from microfilms, and a police box of photographs has vanished. You can, and I plan to, read more about it in Scott Ellsworth’s The Groundbreaking.

The commission that has planned the commemoration used to include Republican Governor Kevin Stitt, but when he signed the bill that effectively outlawed teaching the history of racism in Oklahoma, the rest of the commission removed him from membership. Stitt attempted no defense of his actions.

The oppression of blacks (and even more so of other minorities) in America has tarnished our international reputation, even now that the president who at least went along with it is out of office. Every time there is a new police shooting of an unarmed black man by a white officer, especially when no action is taken, as recently in North Carolina, the world thinks more and more of us as a land of racial oppression. This is something that even Joe Biden cannot change, and the world knows it.

My point in this essay is that this has been going on for a long time. In 1964, Jorgen Bisch visited China, in the heyday of its Maoist oppression, and wrote an article about what he saw for National Geographic (published November 1964). One of the things that he saw, and that alarmed him, was “communist propaganda.” Schoolchildren had written essays about how white Americans oppressed blacks. The author saw some of those essays posted on a wall, and took a photo of them.

In one of the essays, a white Uncle Sam is walking away from a black man. In another, a black American is holding up a red flag of liberation from racist oppression. Look at this photo, because I very much doubt you will see it anywhere else.

At that time, white Americans really were oppressing and sometimes killing blacks, and worse was to come. This bad image of Uncle Sam was justified. Resentment toward America was justified.

We recognize, of course, that the Chinese government was far worse, not just toward its own citizens who appeared to even slightly differ from Chairman Mao’s views, but also in the way it treated its own minority groups—to the extent that you may not have even known that there were minority ethnicities in China. Even the normally meek Joe Biden has called China’s treatment of the Uyghur minority “genocide.”

I believe we are not as bad as the communists were and are. But it sure doesn’t help much when we project to the world the racist hatred that we do have. Our right-wing extremism plays right into the propaganda machines of our competitors and potential enemies.

And we use Christianity to justify it. I recently went to a fundamentalist church meeting in Durant, Oklahoma, where the speaker proclaimed that the new requirements to teach about racism were satanic. He meant this literally. His evidence was that the watchwords for the fight against racism were Diversity, Inclusion, and Equity—the first letters of which spell DIE. This shit is so extreme that you can’t make it up. The speaker digressed from his theme only long enough to proclaim that Biden stole 41 million votes (I did not make this number up) from Trump.

This is a blog about science and evolution. This essay, like many others, reinforces the theme that there is no biological or evolutionary justification for racism.

Armed protests are planned for the Race Massacre commemoration. What could possibly go wrong? As a white-presenting Tulsa resident, I’m getting a little nervous.

Big Headlines! Why America Will Never Convert to Electric Vehicles

It’s the big headline today! Ford is going to formally announce its new all-electric F-150 pickup truck! Oh, can’t you just barely contain the excitement! Yesterday, President Biden took one for a test drive in a lot where everything a 78-year-old man might run over had been removed.


This year, General Motors announced that it plans to phase out electric vehicles by 2035 and manufacture only electric vehicles. (Note: this site may have a paywall.) I here briefly explain why this will not happen.

It is true that hybrid and electric vehicles get much better fuel efficiency, without sacrificing maneuverability, than gasoline vehicles. Anyone like myself who has driven one will attest to this. I enjoy my hybrid more than any car I have ever owned. Mine is a Prius but I have no reason to doubt the quality of other brands.

But it will never happen in America, or at least in Oklahoma.

This is because, in America, the purpose of a vehicle is not only, perhaps not mainly, transportation. At least where I live in Oklahoma, the major purpose of a vehicle for many people is not transportation, but to express dominance, fury, and frustration to everyone within hearing or collision range.

Redneck Okies love to drive around big, noisy, fuming trucks even when they have nowhere they need to go. They drive them fast, which means they sometimes cannot control them. For this purpose, an electric vehicle simply will not work.

First, the vehicles have to be big. Size itself should be no deterrent to the adoption of hybrid and electric vehicles. Rednecks think that nobody can admire them if they drive a small vehicle. By actual count, about one-third of all vehicles I have seen in Oklahoma are big pickup trucks. Therefore, most electric vehicles will be unacceptable to redneck Okies though perhaps to other Oklahomans.

Second, the vehicles have to be heavy. One of the ways in which hybrid and electric vehicles get good fuel efficiency is by using lightweight components. But redneck Okies want to have not just large trucks but heavy ones. The reason for this is that they want to express their fury by driving around a vehicle that can bash other vehicles without harming their own. To them, the entire system of roads is a potential demolition derby. This, at least, has been my experience. In my family, we have had collisions that were not our fault on four occasions in the last couple of decades. In each case, the driver was a white man with a larger vehicle, on two occasions a large truck. One of those collisions—very recent, and an ongoing source of grief—was a hit-and-run in which the white man with the big pickup drove away from the scene, after causing an injury. The victims were my daughter, son-in-law, and two grandchildren. In another case, my vehicle was totaled by a pickup truck that did not get even a scratch—and the driver had false insurance cards. In none of these cases did the police actually seek out the drivers. It was, instead, the insurance companies that did so. Public safety does not matter; only profit. But at least there is profit in the service of public safety, from time to time. In order for a pickup truck to crush a smaller vehicle, it does not need to just be large but to be heavy. Electric and hybrid vehicles, even when large, are relatively light.

Third, the vehicle has to produce a lot of noise. The redneck drivers want everyone around them to hear their dominance, fury, and frustration. At both of my residences in Oklahoma, there is nearly a constant stream of big pickup trucks that are extremely loud. The drivers want us to admire them—and they assume everyone admires a loud truck. Maybe the redneck guys think they can get a gal that way. “Oh, wow, he must be such a man—he can push down a gas pedal!” Whether there really are any women who are that stupid or not I do not know. When I see the looks on the faces of the drivers, I sometimes see fury and frustration. Electric and hybrid vehicles are quiet. By actual count, at least half of the beg pickup trucks I see are loud. The technology exists for even a heavy truck to be quiet, as about half of them are. But a quiet truck is, to the rednecks among Oklahomans, unacceptable.

Fourth, the vehicle has to produce a lot of fumes. A truck with good fuel efficiency cannot produce fumes. Fumes are a way for the driver to create a space of dominance around him an to antagonize other people.

For these four reasons, hybrid and electric vehicles will never predominate in Oklahoma, unless there is a complete, and nearly impossible, shift away from the redneck culture. Here in Oklahoma, we still fly confederate flags, for God’s sake (at least the rednecks think it is for God’s sake).

Arizona Ballot Audit: Miracles in the Service of Racism

This week, the Arizona re-audit of 2020 election ballots received international attention. This is a science blog. The Arizona re-audit of ballots provides a good opportunity to examine the process of scientific inquiry, in fact the process of determining the truth, and the results are not pretty. They indicate a strong tendency within the Arizona Republican Party, and the Republican Party in general, toward racism.

AP photo

Most Arizona Republicans are, we assume, not racist. But enough of them are that they have started a conspiracy theory: that 20,000 ballots were flown in from China pre-marked for Biden and Harris; that these ballots were stuffed into ballot boxes, thus contributing to a Democratic victory in Arizona. And the rest of the Arizona Republicans, even those who call the conspiracy theorists crazy and unhinged, are going along with them in support of the re-audit. 

I will apply some of the ideas in my recent book, Scientifically Thinking, to this claim, not because the conspiracy theory deserves any examination, but in order to learn some things, some very disturbing things, about Republicans.

First, there is open and obvious bias in the re-audit. The contractor conducting the audit is called CyberNinjas. With a name like that, the far-right Republican bias of the contractor is obvious. They are looking only for things that will, in their estimation, prove the Chinese connection, and can easily overlook any evidence to the contrary, even if individual employees do not intend to do so.

Second, the conspiracy claim is untestable. If the Republicans find any ballots that they consider to be fraudulent, they will claim that they have proven that the election was stolen—a claim that Donald Trump still makes, and that about half of Republicans believe with religious fervor, even if they do not believe the China theory. But if they do not, they will merely claim that the fraud was so perfect that it left no evidence. That is, the conspiracy theorists have already decided that they are correct, no matter which conclusion is reached by the audit.

Third, is their scenario even possible? How could China have gotten 20,000 ballots slipped into ballot boxes in Arizona? Did Chinese nationals carry ballots with them to the United States, travel to Arizona, and cram the ballots in? Is there any evidence that there was an influx of Chinese nationals going to Arizona? Or, perhaps, the Chinese government sent them to Chinese nationals who were already here. Since there is no evidence of Chinese nationals visiting Arizona or stuffing ballots, then it must have been Asian Americans who did it and did so without leaving any evidence. Sneaky devils! And that is my point. This conspiracy theory is racist because it buys in with widespread hatred of Asian Americans, which came to national attention in 2021. It would require supernatural powers for the Asian Americans to sneak the ballots into the boxes, and to coordinate this activity among themselves without the use of social media. That is, they would have to be demons. This is something that some Arizona Republicans believe, and the others are willing to consider as a possibility.

Fourth, what are the criteria for the evidence? I can hardly say it, it is so weird: they are looking for bamboo fibers in the paper on which the ballots were printed. Bamboo fibers in the paper would, they think, prove that the ballots were printed in China. Most Chinese paper is probably made from the wood of poplar, of which China has large plantations. But even more important is the question about how to recognize bamboo fibers in the paper. One question is, how much bamboo would they consider to be enough bamboo to call it bamboo-based paper? But even more important is the question about how to recognize bamboo fibers in the first place. A microscopic view of bamboo xylem (found here but which I cannot copy for this essay) looks almost the same as any other xylem, which is the kind of fiber from which paper is typically made. My point is that the conspiracy theorists never bothered to specify how bamboo fibers were to be recognized.

None of this really matters, of course. The Arizona Republican racists will continue to claim that Trump won the state and national election, even without ANY evidence to back it up. To them, it is a matter of religious devotion. Former Republican Senator Jeff Flake (warning: this site has a paywall and may demand money from you to look at the article) said in a radio interview on May 14, 2021 that his party (if they allow him to remain) is in denial of reality. I would go further and say that they do not believe there is such a thing as reality except whatever Donald Trump asserts. That is their entire reality.

This is such an extreme position—not simply unscientific, but against the very basis of human consciousness—that some Republicans are calling for others to form a new party.

Bring It On, Comrade: We Love Being Vulnerable

Our energy system is wide open to Russian cyberattacks and we are just fine with it. Go ahead, comrade, bring it on. Shut us down so that we don’t have any oil and gas. We’re lying here with our fat bellies to the sun just waiting for you to stab us.

By now everyone has heard about the cyberattack on the pipeline in the eastern US that briefly shut down supplies of oil and gas to the southeastern US. Colonial Pipeline paid $5 in ransom to the attackers in cryptocurrency. The cyberattackers were merely identified as Eastern European.

But what if the price they asked was too high, and the pipeline continued to be shut down?

Or what if the cyberattack had been on Cushing, Oklahoma? This is the town through which all the oil and gas for the entire country flows, or so I am told, though I find this hard to believe. It does, however, have an effect on the oil industry all out of proportion to its size: it stores 13% of the oil in America.

Most of the problems with the Colonial Pipeline cyberattack was panic buying by people who feared that they would be temporarily without gasoline. But what if the cyberattack was prolonged, or if it shut down Cushing?

Because of pipelines, our oil supplies are vulnerable to attack—formerly physical attack by terrorists, and now cyberattacks by our comrades overseas. There is not much we can do about this. Oil comes from wells, travels through pipes, to refineries and then to retail points.

But renewable energy is not usually so vulnerable. You can collect solar energy, either passively through mirrors or directly into electricity, anywhere. It can be distributed on a local grid. And the wind blows everywhere. I suppose cyberattackers could shut solar and wind energy down, but it would take thousands of attacks.

We have known this for decades. I grew up in Cushing. We moved away in 1964. My parents told me, while we were there, that Cushing was at the top of the Soviet nuclear hit list, because of the oil “tank farms” and pipelines.

Not only to prevent global warming, but also to prevent cyberattacks that can cripple our energy system, we need to make a rapid transition away from fossil fuels, even if Comrade Trump insists that we should not.
