Carbon Dioxide Quotes

...and his eyes were so green they could turn carbon dioxide into oxygen.

Life isn't just about taking in oxygen and giving out carbon dioxide.

Some molecules - ammonia, carbon dioxide, water - show up everywhere in the universe, whether life is present or not. But others pop up especially in the presence of life itself. Among the biomarkers in Earth's atmosphere are ozone-destroying chlorofluorocarbons from aerosol sprays, vapor from mineral solvents, escaped coolants from refrigerators and air conditioners, and smog from the burning of fossil fuels. No other way to read that list: sure signs of the absence of intelligence.

The human eye has to be one of the cruelest tricks nature ever pulled. We can see a tiny, cone-shaped area of light right in front of our faces, restricted to a very narrow band of the electromagnetic spectrum. We can’t see around walls, we can’t see heat or cold, we can’t see electricity or radio signals, we can’t see at a distance. It is a sense so limited that we might as well not have it, yet we have evolved to depend so heavily on it as a species that all other perception has atrophied. We have wound up with the utterly mad and often fatal delusion that if we can’t see something, it doesn’t exist. Virtually all of civilization’s failures can be traced back to that one ominous sentence: ‘I’ll believe it when I see it.’ We can’t even convince the public that global warming is dangerous. Why? Because carbon dioxide happens to be invisible.

...the only thing that could justify your continuing existence on the planet would be if you started breathing carbon dioxide and exhaling oxygen.

As far as food is concerned, the great extravagance is not caviar or truffles, but beef, pork and poultry. Some 38 percent of the world's grain crop is now fed to animals, as well as large quantities of soybeans. There are three times as many domestic animals on this planet as there are human beings. The combined weight of the world's 1.28 billion cattle alone exceeds that of the human population. While we look darkly at the number of babies being born in poorer parts of the world, we ignore the over-population of farm animals, to which we ourselves contribute...[t]hat, however, is only part of the damage done by the animals we deliberately breed. The energy intensive factory farming methods of the industrialised nations are responsible for the consumption of huge amounts of fossil fuels. Chemical fertilizers, used to grow the feed crops for cattle in feedlots and pigs and chickens kept indoors in sheds, produce nitrous oxide, another greenhouse gas. Then there is the loss of forests. Everywhere, forest-dwellers, both human and non-human, can be pushed out. Since 1960, 25 percent of the forests of Central America have been cleared for cattle. Once cleared, the poor soils will support grazing for a few years; then the graziers must move on. Shrub takes over the abandoned pasture, but the forest does not return. When the forests are cleared so the cattle can graze, billions of tons of carbon dioxide are released into the atmosphere. Finally, the world's cattle are thought to produce about 20 percent of the methane released into the atmosphere, and methane traps twenty-five times as much heat from the sun as carbon dioxide. Factory farm manure also produces methane because, unlike manured dropped naturally in the fields, it dies not decompose in the presence of oxygen. All of this amounts to a compelling reason...for a plant based diet.

It’s] pretty clear that times of high carbon dioxide—and especially times when carbon dioxide levels rapidly rose—coincided with the mass extinctions,” writes University of Washington paleontologist and End-Permian mass extinction expert Peter Ward. “Here is the driver of extinction.

I can't believe that we have reached the end of everything. The red dust is frightening. The carbon dioxide is real. Water is expensive. Bio-tech has created as many problems as it has fixed, but we're here, we're alive, we're the human race, we have survived wars and terrorism and scarcity and global famine, and we have made it back from the brink, not once but many times. History is not a suicide note - it's a record of our survival.

Life isn't just about taking in oxygen and giving out carbon dioxide. You can stay there accepting everything from the Taliban or you can make a stand against them.

Because our lungs regularly deal with carbon dioxide, they see nothing wrong with absorbing its cousin, SiO2, which can be fatal. Many dinosaurs might have died this way when a metropolis-sized asteroid or comet struck the earth 65 million years ago.

I had thought fermentation was controlled death. Left alone, a head of cabbage molds and decomposes. It becomes rotten, inedible. But when brined and stored, the course of its decay is altered. Sugars are broken down to produce lactic acid, which protects it from spoiling. Carbon dioxide is released and the brine acidifies. It ages. Its color and texture transmute. Its flavor becomes tarter, more pungent. It exists in time and transforms. So it is not quite controlled death, because it enjoys a new life altogether. The memories I had stored, I could not let fester. Could not let trauma infiltrate and spread, to spoil and render them useless. They were moments to be tended. The culture we shared was active, effervescent in my gut and in my genes, and I had to seize it, foster it so it did not die in me. So that I could pass it on someday. The lessons she imparted, the proof of her life lived on in me, in my every move and deed. I was what she left behind. If I could not be with my mother, I would be her.

The forest is really a gigantic carbon dioxide vacuum that constantly filters out and stores this component of the air.

I watch the vein in his neck pulse. I watch him convert oxygen to carbon dioxide. I watch him existing and existing and existing.

Syntax overrides carbon dioxide.

But that's the grand irony: countries will go to war to decide who owns the hydrocarbons and then countries gather to decide who does not own the carbon dioxide.

For every ten pounds of fat lost in our bodies, eight and a half pounds of it comes out through the lungs; most of it is carbon dioxide mixed with a bit of water vapor. The rest is sweated or urinated out. This is a fact that most doctors, nutritionists, and other medical professionals have historically gotten wrong. The lungs are the weight-regulating system of the body.

My lungs, now full of carbon dioxide, panic. But the adrenaline rush doesn’t give me the strength I need to escape. It just keeps me awake so I can experience death in more detail. Thanks, adrenal glands.

People ask me all the time if I believe in God. I tell them that I’m Episcopalian, or that I go to church, but they don’t care about that. They only want to know if I believe in God, and I can’t answer them, because I don’t know how to deal with the question’s in. Do I believe in God? I believe around God. But I can only believe in what I am in—sunlight and shadow, oxygen and carbon dioxide, solar systems and galaxies.

The potatoes grew bigger as carbon dioxide increased. This was not a surprise. We also saw that these big potatoes were less nutritious, much lower in protein content, no matter how much fertilizer we gave them. This was a bit of a surprise. It is also bad news, because the poorest and hungriest nations of the world rely on sweet potatoes for a significant amount of dietary protein. It looks as if the bigger potatoes of the future might feed more people while nourishing them less. I don’t have an answer for that one. The

Southam’s research was only one of hundreds of similarly unethical studies. Beecher published a detailed list of the twenty-two worst offenders, including researchers who’d injected children with hepatitis and others who’d poisoned patients under anesthesia using carbon dioxide. Southam’s study was included as example number 17. Despite scientists’ fears, the ethical crackdown didn’t slow scientific progress. In fact, research flourished. And much of it involved HeLa.

It is worse, much worse, than you think. The slowness of climate change is a fairy tale, perhaps as pernicious as the one that says it isn’t happening at all, and comes to us bundled with several others in an anthology of comforting delusions: that global warming is an Arctic saga, unfolding remotely; that it is strictly a matter of sea level and coastlines, not an enveloping crisis sparing no place and leaving no life undeformed; that it is a crisis of the “natural” world, not the human one; that those two are distinct, and that we live today somehow outside or beyond or at the very least defended against nature, not inescapably within and literally overwhelmed by it; that wealth can be a shield against the ravages of warming; that the burning of fossil fuels is the price of continued economic growth; that growth, and the technology it produces, will allow us to engineer our way out of environmental disaster; that there is any analogue to the scale or scope of this threat, in the long span of human history, that might give us confidence in staring it down. None of this is true. But let’s begin with the speed of change. The earth has experienced five mass extinctions before the one we are living through now, each so complete a wiping of the fossil record that it functioned as an evolutionary reset, the planet’s phylogenetic tree first expanding, then collapsing, at intervals, like a lung: 86 percent of all species dead, 450 million years ago; 70 million years later, 75 percent; 125 million years later, 96 percent; 50 million years later, 80 percent; 135 million years after that, 75 percent again. Unless you are a teenager, you probably read in your high school textbooks that these extinctions were the result of asteroids. In fact, all but the one that killed the dinosaurs involved climate change produced by greenhouse gas. The most notorious was 250 million years ago; it began when carbon dioxide warmed the planet by five degrees Celsius, accelerated when that warming triggered the release of methane, another greenhouse gas, and ended with all but a sliver of life on Earth dead. We are currently adding carbon to the atmosphere at a considerably faster rate; by most estimates, at least ten times faster. The rate is one hundred times faster than at any point in human history before the beginning of industrialization. And there is already, right now, fully a third more carbon in the atmosphere than at any point in the last 800,000 years—perhaps in as long as 15 million years. There were no humans then. The oceans were more than a hundred feet higher.

I find it sad, but all too human, that there are vast bureaucracies concerned about nuclear waste, huge organizations devoted to decommissioning nuclear power stations, but nothing comparable to deal with that truly malign waste, carbon dioxide.

There’s one last way we can cut down on emissions from the food we eat: by wasting less of it. In Europe, industrialized parts of Asia, and sub-Saharan Africa, more than 20 percent of food is simply thrown away, allowed to rot, or otherwise wasted. In the United States, it’s 40 percent. That’s bad for people who don’t have enough to eat, bad for the economy, and bad for the climate. When wasted food rots, it produces enough methane to cause as much warming as 3.3 billion tons of carbon dioxide each year.

He could taste the familiar tang of museum air - an arid, deionized essence that carried a faint hint of carbon - the product of industrial, coal-filter dehumidifiers that ran around the clock to counteract the corrosive carbon dioxide exhaled by visitors.

Yet we could not feed on the carbon dioxide that results from the reaction. And so Simon is quite right in pointing out to me, as he did, that actually the energy content of our food does matter; so my mocking at the menu cards that indicate it was out of place.

(Chris) “Katie, seriously. He’s a jock with entitlement issues. What about that could I possibly like?” “Well…” Her friend trailed off and Chris could hear Katie’s fingers drumming a pattern on the table. “You guys have a lot in common.” Chris snorted and started mixing the salad with two large forks. “What, we both convert oxygen into carbon dioxide?

Thinking! Thinking! The process should no longer be merely this feeble flurry of hailstones that raises a little dust. It should be something quite different. Thinking should be a terrifying process. When the earth thinks, whole towns crumble to the ground and thousands of people die. Thinking: raising boulders, hollowing out valleys, preparing tidal waves at sea. Thinking like a town: that's to say: eight million inhabitants, twelve million rats, nine million pints of carbon dioxide, two billion tons. Grey light. Cathedral of light. Din. Sudden flashes. Low-lying blanket of black cloud. Flat roofs. Fire alarms. Elevators. Streets. Eighteen thousand miles of streets. 145 million electric light bulbs.

If food was no longer obliged to make intercontinental journeys, but stayed part of a system in which it can be consumed over short distances, we would save a lot of energy and carbon dioxide emissions. And just think of what we would save in ecological terms without long-distance transportation, refrigeration, and packaging--which ends up on the garbage dump anyway--and storage, which steals time, space, and vast portions of nature and beauty.

Your carbon dioxide is breaking my concentration.

Writing is my oxygen. Music is my carbon dioxide.

Assuming that humans continue to burn fossil fuels, the oceans will continue to absorb carbon dioxide and will become increasingly acidified.

Declining emissions and rising atmospheric concentrations point to a stubborn fact about carbon dioxide: once it’s in the air, it stays there. How long, exactly, is a complicated question; for all intents and purposes, though, CO2 emissions are cumulative. The comparison that’s often made is to a bathtub. So long as the tap is running, a stoppered tub will continue to fill. Turn the tap down, and the tub will still keep filling, just more slowly. To

But our current experiment—quickly injecting huge amounts of carbon dioxide into the atmosphere—has in fact been run many times before in the geological past, and it never ends well.

These early, single-celled organisms unwittingly transformed Earth’s carbon dioxide-rich atmosphere into one with sufficient oxygen to allow aerobic organisms to emerge and dominate the oceans and land.

All of them claimed to have gained a boost in performance and blunted the symptoms of respiratory problems, simply by decreasing the volume of air in their lungs and increasing the carbon dioxide in their bodies.

Bill McKibben named his climate change advocacy group 350.org, because 350 ppm of atmospheric carbon dioxide is what Dr. James Hansen, former head of the Goddard Institute for Space Studies and one of the most respected climatologists in the world, says is the maximum level to “preserve a planet similar to that on which civilization developed and to which life on Earth is adapted.” Tragically, we have now exceeded 400 ppm.

Paris was one of the justifications the Obama administration used as part of the regulatory record to justify the cost and benefits of the Clean Power Plan.” That was an Obama-era 460-page rule to lower carbon dioxide emitted by power plants that the EPA estimated would save 4,500 lives a year. Pruitt was already moving to end the policy.

I even felt resentful towards my body, towards it's demands for sleep. for food, for drink, for bodily functions. I thought that life should stop until Ben was found. Clocks should no longer tick, oxygen should no longer be exchanged for carbon dioxide in our lungs, and our hearts should not pump. Only when he was back should normal service resume

Ethanol plus carbon dioxide was like a demon spawn pounding against the frontal lobes of my head from the previous night at the bar. Somewhere in the city there was a church bell ringing, and—oh, not a bell. That was my phone. My head pounded and I felt dizzy, like I was spinning in circles on a Tilt-A-Whirl ride. Slowly, I opened an eye to try and find my cell phone. I groaned as I reached for the blue- and-silver-plated device on my nightstand. The spins from al- cohol sucked.

The sense of respiration is an example of our natural sense relationship with the atmospheric matrix. Remember, respiration means to re-spire, to re-spirit ourselves by breathing. It, too, is a consensus of many senses. We may always bring the natural relationships of our senses and the matrix into consciousness by becoming aware of our tensions and relaxations while breathing. The respiration process is guided by our natural attraction to connect with fresh air and by our attraction to nurture nature by feeding it carbon dioxide and water, the foods for Earth that we grow within us during respiration. When we hold our breath, our story to do so makes our senses feel the suffocation discomfort of being separated from Earth's atmosphere. It draws our attention to follow our attraction to air, so we inspire and gain comfort. Then the attraction to feed Earth comes into play so we exhale food for it to eat and we again gain comfort. This process feels good, it is inspiring. Together, we and Earth conspire (breathe together) so that neither of us will expire. The vital nature of this process is brought to consciousness when we recognize that the word for air, spire, also means spirit and that psyche is another name for air/spirit/soul.

Instructions for Dad. I don't want to go into a fridge at an undertaker's. I want you to keep me at home until the funeral. Please can someone sit with me in case I got lonely? I promise not to scare you. I want to be buried in my butterfly dress, my lilac bra and knicker set and my black zip boots (all still in the suitcase that I packed for Sicily). I also want to wear the bracelet Adam gave me. Don't put make-up on me. It looks stupid on dead people. I do NOT want to be cremated. Cremations pollute the atmosphere with dioxins,k hydrochloric acid, hydrofluoric acid, sulphur dioxide and carbon dioxide. They also have those spooky curtains in crematoriums. I want a biodegradable willow coffin and a woodland burial. The people at the Natural Death Centre helped me pick a site not for from where we live, and they'll help you with all the arrangements. I want a native tree planted on or near my grave. I'd like an oak, but I don't mind a sweet chestnut or even a willow. I want a wooden plaque with my name on. I want wild plants and flowers growing on my grave. I want the service to be simple. Tell Zoey to bring Lauren (if she's born by then). Invite Philippa and her husband Andy (if he wants to come), also James from the hospital (though he might be busy). I don't want anyone who doesn't know my saying anything about me. THe Natural Death Centre people will stay with you, but should also stay out of it. I want the people I love to get up and speak about me, and even if you cry it'll be OK. I want you to say honest things. Say I was a monster if you like, say how I made you all run around after me. If you can think of anything good, say that too! Write it down first, because apparently people often forget what they mean to say at funerals. Don't under any circumstances read that poem by Auden. It's been done to death (ha, ha) and it's too sad. Get someone to read Sonnet 12 by Shakespeare. Music- "Blackbird" by the Beatles. "Plainsong" by The Cure. "Live Like You Were Dying" by Tim McGraw. "All the Trees of the Field Will Clap Their Hands" by Sufian Stevens. There may not be time for all of them, but make sure you play the last one. Zoey helped me choose them and she's got them all on her iPod (it's got speakers if you need to borrow it). Afterwards, go to a pub for lunch. I've got £260 in my savings account and I really want you to use it for that. Really, I mean it-lunch is on me. Make sure you have pudding-sticky toffee, chocolate fudge cake, ice-cream sundae, something really bad for you. Get drunk too if you like (but don't scare Cal). Spend all the money. And after that, when days have gone by, keep an eye out for me. I might write on the steam in the mirror when you're having a bath, or play with the leaves on the apple tree when you're out in the garden. I might slip into a dream. Visit my grave when you can, but don't kick yourself if you can't, or if you move house and it's suddenly too far away. It looks pretty there in the summer (check out the website). You could bring a picnic and sit with me. I'd like that. OK. That's it. I love you. Tessa xxx

Humans do think ahead more than any other animal, but that isn’t saying much. The oceans are filled with plastic, and the atmosphere is filled with carbon dioxide. We’ve built enough bombs to destroy everything ten times over, but apparently solar panels were just one expense too many!

These are the oldest memories on earth, the time codes carried in every chromosome and gene. Every step we’ve taken in our evolution is a milestone inscribed with organic memories. From the enzymes controlling the carbon-dioxide cycle, to the organization of the brachial plexus and the nerve pathways of the pyramid cells of the mid-brain. Each is a record of a thousand decisions taken in a chemical crisis. Just as psychoanalysis reconstructs the original traumatic situation in order to release the repressed material, so we are now being plunged back into the archaeopsychic past, uncovering the ancient taboos and drives that have been dormant for epochs.

Originally, the atoms of carbon from which we’re made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life—the carbohydrates, amino acids, proteins, and lipids—is by means of photosynthesis. Using sunlight as a catalyst the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the simple organic compounds that stand at the base of every food chain. It is more than a figure of speech to say that plants create life out of thin air.

Driving a hybrid car could save about one ton of carbon-dioxide emissions per year but adopting a plant-based diet would save nearly one and a half tons over a comparable period." "If every American reduced chicken consumption by one meal per week, the carbon-dioxide savings would be equivalent to removing 500,000 cars form the road." In a given year, "the number of animals killed to satisfy American palates is 8.6 billion, or 29 animals per average American meat eater. The total number of animals killed on land and sea was approximately 80 billion, or 270 per American meat and fish eater - making the average number of animals consumed in one American lifetime 21,000.

After a while, the CO2 (carbon dioxide) absorbers in the suit were expended. That’s really the limiting factor to life support. Not the amount of oxygen you bring with you, but the amount of CO2 you can remove. In the Hab, I have the oxygenator, a large piece of equipment that breaks apart CO2 to give the oxygen back. But the space suits have to be portable, so they use a simple chemical absorption process with expendable filters. I’d been asleep long enough that my filters were useless.

My instinct, of course, is to imagine us as one of many planets racing its evolution against its sun--merely one in the galactic Darwinian pursuit. But maybe we're not. Maybe all this talk of the inevitability of aliens is garbage and we're miraculously, beautifully alone in our biological success. What if we're winning? What if we're actually the most evolved intelligence in all this big bang chaos? What if other planets have bacteria and single-celled genotypes but nothing more? The precedent is all the more pressing. Humans alone could be winning the race against our giant gas time bomb and running with the universal Olympic torch. What an honor. What a responsibility. What a gift we have been given to be born in an atmosphere with oxygen and carbon dioxide and millions of years and phenotypes cheering us on with recycles of energy. The thing is, I think we can make it. I think we can shove ourselves into spaceships before things get too cold. I only hope we don't fuck things up before that. Because millions of years is a long time and I don't want to let the universe down.

Every day, sometimes when I am doing my meditation practice and sometimes when I am working at my computer or sitting in my car waiting for a traffic light to change or sharing a meal with friends, I turn my attention to my breath and visualize myself on some inner plane of the imagination turning my face toward that which is larger than myself—the Great Mystery. I only have to turn my face toward it. I become aware of the temperature of the air touching my cheek. I imagine the molecules of oxygen and hydrogen and carbon dioxide colliding in exuberant activity, caressing the skin of my face. And I become aware that these molecules are alive with a vibration, a presence that is there also in the cells of my skin and in the molecules of those cells and in the atoms and subatomic particles of those. Slowly I turn my attention to an inner view of the landscape around and within me, and I become aware of this presence, like the hum of a great song constantly reverberating throughout and emanating from my body, the chair supporting me, the ground beneath me, and the people around me. And I know this presence as a whole that is larger than the sum of the parts and yet inseparable from the parts—including me—which are in a state of constant change. And I experience this presence, this bloodred thread of being that runs through the dark tapestry of daily life, as that which gives me the ability to truly know each other as another myself—as compassion.

In the Gaia theory air, water, and soil are major components of one central organism, planet Earth. What we typically think of as life - the plants and animals that inhabit the earth - has evolved merely to regulate the chemistry of the biosphere. Humans are insignificant participants, far less important to the life cycle than termites. Even the imbalance that we have created by adding massive quantities of carbon dioxide to the atmosphere may be brought back to acceptable levels by other organisms functioning in their capacity to correct excesses.

When Al Gore urges the citizenry to sacrifice their plastic shopping bags, their air-conditioning, their extraneous travel, the agnostics grumble that human activity accounts for just 2 percent of global carbon-dioxide emissions, with the remainder generated by natural processes like plant decay.

The plants are our greatest friends. They give us oxygen to breathe, food, water, shelter, medicine, and even fuel. You may enslave a pet with domesticity, a dog or cat, but eventually when the food runs out, they will be gone, by choice. The plants, however, never leave us. Perhaps that is why they have already begun to reduce carbon dioxide, the gas of life, and sunlight by way of chemical trails in the sky.

In her memoir of living among the Bushmen, The Old Way: A Story of the First People, my friend Liz lovingly invokes an image first coined by evolutionary biologist Richard Dawkins: “You are standing beside your mother, holding her hand. She is holding her mother’s hand, who is holding her mother’s hand. . . . ” Eventually the line stretches three hundred miles long and goes back five million years, and the clasping hand of the ancestor looks like that of a chimpanzee. I loved picturing one of Octavia’s arms stretching out to meet one of her mother’s arms, and one of her mother’s mother’s arms, and her mother’s mother’s mother’s. . . . Suckered, elastic arms, reaching back through time: an octopus chorus line stretching not just hundreds, but many thousands of miles long. Back past the Cenozoic, the time when our ancestors descended from the trees; back past the Mesozoic, when dinosaurs ruled the land; back past the Permian and the rise of the ancestors of the mammals; back, past the Carboniferous’s coal-forming swamp forests; back past the Devonian, when amphibians emerged from the water; back past the Silurian, when plants first took root on land—all the way to the Ordovician, to a time before the advent of wings or knees or lungs, before the fishes had bony jaws, before blood pumped from a multichambered heart. More than 500 million years ago, the tides would have been stronger, the days shorter, the year longer, and the air too high in carbon dioxide for mammals or birds to breathe. All the earth’s continents huddled in the Southern Hemisphere. And yet still, the arm of Octavia’s ancestor, sensitive, suckered, and supple, would have been recognizable as one of an octopus.

A typical 100-kilowatt-hour Tesla lithium-ion battery is built in China on a largely coal-powered grid. Such an energy- and carbonintensive manufacturing process releases 13,500 kilograms of carbon dioxide emissions, roughly equivalent to the carbon pollution released by a conventional gasoline-powered car traveling 33,000 miles. That 33,000-miles figure assumes the Tesla is only recharged by 100 percent greentech-generated electricity.

Packman explained that overbreathing can have other, deeper effects on the body beyond just lung function and constricted airways. When we breathe too much, we expel too much carbon dioxide, and our blood pH rises to become more alkaline; when we breathe slower and hold in more carbon dioxide, pH lowers and blood becomes more acidic. Almost all cellular functions in the body take place at a blood pH of 7.4, our sweet spot between alkaline and acid.

The challenge we face is not (only) to reduce or stabilize concentration of atmospheric carbon dioxide, but to live in productive relationship with the dynamic systems that govern a changing planet. This is a new challenge because humanity is young and now constitutes an important planetary force in a way that is unprecedented. Anthropogenic climate change is the harbinger of a new world in which humans have become a dominant force on Earth’s natural systems.

What has Capitalism resolved? It has solved no problems. It has looted the world. It has left us with all this poverty. It has created lifestyles and models of consumerism that are incompatible with reality. It has poisoned the waterways. Oceans, Rivers, Lakes, Seas, the Atmosphere, the Earth. It has produced an incredible waste of resources. I always cite one example; imagine every person in China owned a Car, or aspired to own a Car. Everyone of the 1.1 Billion people in China, or that everyone of the 800 million people in India wished to own a Car, this method, this lifestyle, and Africa did the same, and nearly 450 million Latin Americans did the same. How long would Oil last? How long would Natural Gas last? How long would natural resources last? What would be left of the Ozone layer? What would be left of Oxygen on Earth? What would happen with Carbon Dioxide? And all these phenomenon that are changing the ecology of our world, they are changing Earth, they are making life on our Planet more and more difficult all the time. What model has Capitalism given the world to follow? An example for societies to emulate? Shouldn’t we focus on more rational things, like the education of the whole population? Nutrition, health, a respectable lodging, an elevated culture? Would you say capitalism, with it’s blind laws, it’s selfishness as a fundamental principle, has given us something to emulate? Has it shown us a path forward? Is humanity going to travel on the course charted thus far? There may be talk of a crisis in socialism, but, today, there is an even greater crises in capitalism, with no end in sight.

Earlier, I mentioned a related technology called direct air capture. It involves exactly what the name implies: capturing carbon directly from the air. DAC is more flexible than point capture, because you can do it anywhere. And in all likelihood, it’ll be a crucial part of getting to zero; one study by the National Academy of Sciences found that we’ll need to be removing about 10 billion tons of carbon dioxide a year by mid-century and about 20 billion by the end of the century.

As a result of its investigation, the NIH said that to qualify for funding, all proposals for research on human subjects had to be approved by review boards—independent bodies made up of professionals and laypeople of diverse races, classes, and backgrounds—to ensure that they met the NIH’s ethics requirements, including detailed informed consent. Scientists said medical research was doomed. In a letter to the editor of Science, one of them warned, “When we are prevented from attempting seemingly innocuous studies of cancer behavior in humans … we may mark 1966 as the year in which all medical progress ceased.” Later that year, a Harvard anesthesiologist named Henry Beecher published a study in the New England Journal of Medicine showing that Southam’s research was only one of hundreds of similarly unethical studies. Beecher published a detailed list of the twenty-two worst offenders, including researchers who’d injected children with hepatitis and others who’d poisoned patients under anesthesia using carbon dioxide. Southam’s study was included as example number 17. Despite scientists’ fears, the ethical crackdown didn’t slow scientific progress. In fact, research flourished. And much of it involved HeLa. 18

Blue-green algae, or cyanobacteria, were the first photosynthesizers. They breathed in carbon dioxide and breathed out oxygen. Oxygen is a volatile gas; it causes iron to rust (oxidation) and wood to burn (vigorous oxidation). When cyanobacteria first appeared, the oxygen they breathed out was toxic to nearly all other forms of life. The resulting extinction is called the oxygen catastrophe. After the cyanobacteria pumped Earth’s atmosphere and water full of toxic oxygen, creatures evolved that took advantage of the gas’s volatile nature to enable new biological processes. We are the descendants of those first oxygen-breathers. Many details of this history remain uncertain; the world of a billion years ago is difficult to reconstruct.

What matters most is that we make sure that the most vulnerable, worst-off people living in shantytowns are lifted out of poverty. It is growth, not carbon dioxide reductions, that will prevent the harrowing losses that the world’s poorest endure as a result of hurricanes.

For reasons I do not entirely understand, the clerisy after 1848 turned toward nationalism and socialism, and against liberalism, and came also to delight in an ever-expanding list of pessimisms about the way we live now in our approximately liberal societies, from the lack of temperance among the poor to an excess of carbon dioxide in the atmosphere. Antiliberal utopias believed to offset the pessimisms have been popular among the clerisy. Its pessimistic and utopian books have sold millions. But the twentieth-century experiments of nationalism and socialism, of syndicalism in factories and central planning for investment, of proliferating regulation for imagined but not factually documented imperfections in the market, did not work. And most of the pessimisms about how we live now have proven to be mistaken. It is a puzzle. Perhaps you yourself still believe in nationalism or socialism or proliferating regulation. And perhaps you are in the grip of pessimism about growth or consumerism or the environment or inequality. Please, for the good of the wretched of the earth, reconsider.

They found that temperature and carbon dioxide levels have oscillated in parallel, like two roller coasters moving together, in synchronization over many thousands of years. When one curve rises or falls, so does the other. Most important, they found a sudden spike in temperature and carbon dioxide content happening just within the last century. This is highly unusual, since most fluctuations occur slowly over millennia. This unusual spike is not part of this natural heating process, scientists claim, but is a direct indicator of human activity.

Many people think trees grow so big from soil and water, but this is not true. Trees get their mass from the air. They gobble up airborne carbon dioxide and perform an act of chemical fission by using the energy from sunshine... Essentially, trees are made of air and sunshine.

Over the past fifteen years, the iconoclastic mathematician Irakli Loladze has isolated a dramatic effect of carbon dioxide on human nutrition unanticipated by plant physiologists: it can make plants bigger, but those bigger plants are less nutritious. “Every leaf and every grass blade on earth makes more and more sugars as CO2 levels keep rising,” Loladze told Politico, in a story about his work headlined “The Great Nutrient Collapse.” “We are witnessing the greatest injection of carbohydrates into the biosphere in human history—[an] injection that dilutes other nutrients in our food supply.” Since 1950, much of the good stuff in the plants we grow—protein, calcium, iron, vitamin C, to name just four—has declined by as much as one-third, a landmark 2004 study showed. Everything is becoming more like junk food. Even the protein content of bee pollen has dropped by a third. The problem has gotten worse as carbon concentrations have gotten worse. Recently, researchers estimated that by 2050 as many as 150 million people in the developing world will be at risk of protein deficiency as the result of nutrient collapse, since so many of the world’s poor depend on crops, rather than animal meat, for protein; 138 million could suffer from a deficiency of zinc, essential to healthy pregnancies; and 1.4 billion could face a dramatic decline in dietary iron—pointing to a possible epidemic of anemia. In 2018, a team led by Chunwu Zhu looked at the protein content of eighteen different strains of rice, the staple crop for more than 2 billion people, and found that more carbon dioxide in the air produced nutritional declines across the board—drops in protein content, as well as in iron, zinc, and vitamins B1, B2, B5, and B9. Really everything but vitamin E. Overall, the researchers found that, acting just through that single crop, rice, carbon emissions could imperil the health of 600 million people. In previous centuries, empires were built on that crop. Climate change promises another, an empire of hunger, erected among the world’s poor.

Breathing is one of the most detoxifying actions of the body. Your body is designed to release a great majority of its toxins through breathing. The mere act of exhaling releases carbon dioxide—a natural waste of your body’s metabolism—which has been passed from your bloodstream into your lungs.

SINCE the start of the industrial revolution, humans have burned through enough fossil fuels—coal, oil, and natural gas—to add some 365 billion metric tons of carbon to the atmosphere. Deforestation has contributed another 180 billion tons. Each year, we throw up another nine billion tons or so, an amount that’s been increasing by as much as six percent annually. As a result of all this, the concentration of carbon dioxide in the air today—a little over four hundred parts per million—is higher than at any other point in the last eight hundred thousand years. Quite probably it is higher than at any point in the last several million years. If current trends continue, CO2 concentrations will top five hundred parts per million, roughly double the levels they were in preindustrial days, by 2050. It is expected that such an increase will produce an eventual average global temperature rise of between three and a half and seven degrees Fahrenheit, and this will, in turn, trigger a variety of world-altering events, including the disappearance of most remaining glaciers, the inundation of low-lying islands and coastal cities, and the melting of the Arctic ice cap. But this is only half the story.

Finally, some scientists concede that consciousness is real and may actually have great moral and political value, but that it fulfils no biological function whatsoever. Consciousness is the biologically useless by-product of certain brain processes. Jet engines roar loudly, but the noise doesn’t propel the aeroplane forward. Humans don’t need carbon dioxide, but each and every breath fills the air with more of the stuff. Similarly, consciousness may be a kind of mental pollution produced by the firing of complex neural networks. It doesn’t do anything. It is just there. If this is true, it implies that all the pain and pleasure experienced by billions of creatures for millions of years is just mental pollution. This is certainly a thought worth thinking, even if it isn’t true. But it is quite amazing to realise that as of 2016, this is the best theory of consciousness that contemporary science has to offer us. Maybe

Crutzen wrote up his idea in a short essay, “Geology of Mankind,” that ran in Nature. “It seems appropriate to assign the term ‘Anthropocene’ to the present, in many ways human-dominated, geological epoch,” he observed. Among the many geologic-scale changes people have effected, Crutzen cited the following: • Human activity has transformed between a third and a half of the land surface of the planet. • Most of the world’s major rivers have been dammed or diverted. • Fertilizer plants produce more nitrogen than is fixed naturally by all terrestrial ecosystems. • Fisheries remove more than a third of the primary production of the oceans’ coastal waters. • Humans use more than half of the world’s readily accessible fresh water runoff. Most significantly, Crutzen said, people have altered the composition of the atmosphere. Owing to a combination of fossil fuel combustion and deforestation, the concentration of carbon dioxide in the air has risen by forty percent over the last two centuries, while the concentration of methane, an even more potent greenhouse gas, has more than doubled. “Because of these anthropogenic emissions,” Crutzen wrote, the global climate is likely to “depart significantly from natural behavior for many millennia to come.

In the Amazon, the turn to swidden was unfortunate. Slash-and-burn cultivation has become one of the driving forces behind the loss of tropical forest. Although swidden does permit the forest to regrow, it is wildly inefficient and environmentally unsound. The burning sends up in smoke most of the nutrients in the vegetation—almost all of the nitrogen and half the phosphorus and potassium. At the same time, it pours huge amounts of carbon dioxide into the air, a factor in global warming. (Large cattle ranches are the major offenders in the Amazon, but small-scale farmers are responsible for up to a third of the clearing.) Fortunately, it is a relatively new practice, which means it has not yet had much time to cause damage. More important, the very existence of so much healthy forest after twelve thousand years of use by large populations suggests that whatever Indians did before swidden must have been ecologically more sustainable.

After two centuries of colonization, the air struggle on Mars was still so critical that the V-L Law, the Vegetative-Lynch Law, was still in effect. It was a killing offense to endanger or destroy any plant vital to the transformation of Mars’ carbon dioxide atmosphere into an oxygen atmosphere. Even blades of grass were sacred. There was no need to erect KEEP OFF THE GRASS neons. The man who wandered off a path onto a lawn would be instantly shot. The woman who picked a flower would be killed without mercy. Two centuries of sudden death had inspired a reverence for green growing things that almost amounted to a religion. Foyle

All vertebrates except mammals have nuclei in their red blood cells.In mammals, these cells go through an extra stage of development in which the nucleus is discarded. The resulting cells are smaller, can flow through smaller capillaries, can be packed with more hemoglobin, and thus can carry oxygen and carbon dioxide more efficiently.

The leaves on our little maple, all taken together, weigh thirty-five pounds. Every ounce therein must be pulled from the air or mined from the soil—and quickly—over the course of a few short months. From the atmosphere, a plant gains carbon dioxide, which it will make into sugar and pith. Thirty-five pounds of maple leaves may not taste sweet to you and me, but they actually contain enough sucrose to make three pecan pies, which is the sweetest thing that I can think of right now. The pithy skeleton within the leaves contains enough cellulose to make almost three hundred sheets of paper, which is about the number that I used to print out the manuscript for this book. Our

Imagine that after reaching an atmospheric concentration of 450 ppm sometime in the next decade, we immediately stop all carbon dioxide emissions. By the year 3000, neither atmospheric concentrations of carbon dioxide nor global mean surface temperature would have returned to their pre-industrial baselines, and sea levels would still be rising.

You see the impact of humans on Earth’s environment every day. We are trashing the place: There is plastic along our highways, the smell of a landfill, the carbonic acid (formed when carbon dioxide is dissolved in water) bleaching of coral reefs, the desertification of enormous areas of China and Africa (readily seen in satellite images), and a huge patch of plastic garbage in the Pacific Ocean. All of these are direct evidence of our effect on our world. We are killing off species at the rate of about one per day. It is estimated that humans are driving species to extinction at least a thousand times faster than the otherwise natural rate. Many people naïvely (and some, perhaps, deceptively) argue that loss of species is not that important. After all, we can see in the fossil record that about 99 percent of all the different kinds of living things that have ever lived here are gone forever, and we’re doing just fine today. What’s the big deal if we, as part of the ecosystem, kill off a great many more species of living things? We’ll just kill what we don’t need or notice. The problem with that idea is that although we can, in a sense, know what will become or what became of an individual species, we cannot be sure of what will happen to that species’ native ecosystem. We cannot predict the behavior of the whole, complex, connected system. We cannot know what will go wrong or right. However, we can be absolutely certain that by reducing or destroying biodiversity, our world will be less able to adapt. Our farms will be less productive, our water less clean, and our landscape more barren. We will have fewer genetic resources to draw on for medicines, for industrial processes, for future crops. Biodiversity is a result of the process of evolution, and it is also a safety net that helps keep that process going. In order to pass our own genes into the future and enable our offspring to live long and prosper, we must reverse the current trend and preserve as much biodiversity as possible. If we don’t, we will sooner or later join the fossil record of extinction.

We are told that we are sinning (by emitting CO2), that we have original sin (human greed), which has banished us from Eden (the pre-industrial world), for which we must confess (by condemning irresponsible consumerism), atone (by paying carbon taxes), repent (insisting that politicians pay lip service to climate-change alarm), and seek salvation (sustainability). The wealthy can buy indulgences (carbon offsets) so as to keep flying their private jets, but none must depart from faith (in carbon dioxide) as set out in scripture (the reports of the Intergovernmental Panel on Climate Change). It is the duty of all to condemn heretics (the ‘deniers’), venerate saints (Al Gore), heed the prophets (of the IPCC). If we do not, then surely Judgement Day will find us out (with irreversible tipping points), when we will feel the fires of hell (future heatwaves) and experience divine wrath (worsening storms). Fortunately, God has sent us a sign of the sacrifice we must make – I have sometimes been struck by the way a wind farm looks like Golgotha.

The environmental movement has palsied two generations of American youth. It has diverted much of our high school curricula into the phony field of environmental science. (As legendary physicist Richard Feynman observed, “If a science has an adjective it probably isn’t science.”) At the same time, the movement has turned many universities into apocalyptic nature cults that divert money from education to an obscurantist debauch. Seventy-two percent of Harvard students in late 2012 actually voted to have their university disinvest from all fossil fuels. This movement has already corrupted most branches of government with a carbon dioxide fetish. Now it is debilitating America’s most precious venture assets.

The retreat of the Arctic sea ice, the warming of the oceans, the rapid shrinking of the glaciers, the redistribution of species, the thawing of the permafrost—these are all new phenomena. It is only in the last five or ten years that global warming has finally emerged from the background “noise” of climate variability. And even so, the changes that can be seen lag behind the changes that have been set in motion. The warming that has been observed so far is probably only about half the amount required to bring the planet back into energy balance. This means that even if carbon dioxide were to remain stable at today’s levels, temperatures would still continue to rise, glaciers to melt, and weather patterns to change for decades to come.

at 378 parts per million, current CO2 levels are unprecedented in recent geological history. (The previous high, of 299 parts per million, was reached around 325,000 years ago). It is believed that the last time carbon dioxide levels were comparable to today’s was three and a half million years ago, during what is known as the mid-Pliocene warm period, and it is likely that they have not been much higher since the Eocene, some fifty million years ago. In the Eocene, crocodiles roamed Colorado and sea levels were nearly three hundred feet higher than they are today. A scientist with the National Oceanic and Atmospheric Administration (NOAA) put it to me—only half-jokingly—this way: “It’s true that we’ve had higher CO2 levels before. But, then, of course, we also had dinosaurs.

Yet a third of the food raised or prepared does not make it from farm or factory to fork. That number is startling, especially when paired with this one: Hunger is a condition of life for nearly 800 million people worldwide. And this one: The food we waste contributes 4.4 gigatons of carbon dioxide equivalent into the atmosphere each year—roughly 8 percent of total anthropogenic greenhouse gas emissions.

The discovery of an interaction among the four hemes made it obvious that they must be touching, but in science what is obvious is not necessarily true. When the structure of hemoglobin was finally solved, the hemes were found to lie in isolated pockets on the surface of the subunits. Without contact between them how could one of them sense whether the others had combined with oxygen? And how could as heterogeneous a collection of chemical agents as protons, chloride ions, carbon dioxide, and diphosphoglycerate influence the oxygen equilibrium curve in a similar way? It did not seem plausible that any of them could bind directly to the hemes or that all of them could bind at any other common site, although there again it turned out we were wrong. To add to the mystery, none of these agents affected the oxygen equilibrium of myoglobin or of isolated subunits of hemoglobin. We now know that all the cooperative effects disappear if the hemoglobin molecule is merely split in half, but this vital clue was missed. Like Agatha Christie, Nature kept it to the last to make the story more exciting. There are two ways out of an impasse in science: to experiment or to think. By temperament, perhaps, I experimented, whereas Jacques Monod thought.

The National Academy of Sciences undertook its first major study of global warming in 1979. At that point, climate modeling was still in its infancy, and only a few groups, one led by Syukuro Manabe at the National Oceanic and Atmospheric Administration and another by James Hansen at NASA’s Goddard Institute for Space Studies, had considered in any detail the effects of adding carbon dioxide to the atmosphere. Still, the results of their work were alarming enough that President Jimmy Carter called on the academy to investigate. A nine-member panel was appointed. It was led by the distinguished meteorologist Jule Charney, of MIT, who, in the 1940s, had been the first meteorologist to demonstrate that numerical weather forecasting was feasible. The Ad Hoc Study Group on Carbon Dioxide and Climate, or the Charney panel, as it became known, met for five days at the National Academy of Sciences’ summer study center, in Woods Hole, Massachusetts. Its conclusions were unequivocal. Panel members had looked for flaws in the modelers’work but had been unable to find any. “If carbon dioxide continues to increase, the study group finds no reason to doubt that climate changes will result and no reason to believe that these changes will be negligible,

A 1956 New York Times article quoted Plass as “warning” that “the amount of carbon dioxide released in the atmosphere will be so large that it will have a profound effect on our climate.”33 The next year Revelle testified before congress that the rise of CO2 might turn Southern California and Texas into “real deserts,” and that the Soviet Union might become a maritime power in the twenty-first century as a result of the melting of Arctic ice.34 Climate change had arrived in Washington.35

It is not just the different plants and animals that define the environment. There are all sorts of physical factors as well. Take the atmosphere, for instance. The oxygen levels became usable to us about 400 million years ago, but since then there has been a great variation in the oxygen levels. In the late Jurassic it is possible that the oxygen levels were about 35%, as opposed to 20% at the present day. Indeed this figure has been put forward to explain the survival of the very big dinosaurs, high oxygen concentrations in the breathing air being able to keep the great volumes of tissue oxygenated. On the other hand the proportion of carbon dioxide was also high. This may account for the prolific plant life at the time, carbon dioxide being essential for the good growth of plants. The difference between the composition of the Jurassic atmosphere and that of your own time may make it difficult for you to breathe when you first arrive, but your body will probably adapt to it before long.

When the Earth was only about a third of its eventual size, it was probably already beginning to form an atmosphere, mostly of carbon dioxide, nitrogen, methane and sulphur. Hardly the sort of stuff that we would associate with life, and yet from this noxious stew life formed. Carbon dioxide is a powerful greenhouse gas. This was a good thing, because the Sun was significantly dimmer back then. Had we not had the benefit of a greenhouse effect, the Earth might well have frozen over permanently25, and life might never have got a toehold. But somehow life did. For the next 500 million years the young Earth continued to be pelted relentlessly by comets, meteorites and other galactic debris, which brought water to fill the oceans and the components necessary for the successful formation of life. It was a singularly hostile environment, and yet somehow life got going. Some tiny bag of chemicals twitched and became animate. We were on our way. Four billion years later, people began to wonder how it had all happened.

What is the biggest threat to the future of this planet? An asteroid collision would be—a threat against which we have no defence. But the last big such asteroid collision was about sixty-six million years ago and killed the dinosaurs. A more immediate danger is runaway climate change. A rise in ocean temperature would melt the ice caps and cause the release of large amounts of carbon dioxide. Both effects could make our climate like that of Venus with a temperature of 250 degrees centigrade (482 degrees Fahrenheit).

The first demonstration of the law of conservation of energy was not by a physicist but by a medical man. He demonstrated with rats. If you burn food you can find out how much heat is generated. If you then feed the same amount of food to rats it is converted, with oxygen, into carbon dioxide, in the same way as in burning. When you measure the energy in each case you find out that living creatures do exactly the same as non-living creatures. The law for conservation of energy is as true for life as for other phenomena. Incidentally,

A person breathes in nearly 2 pounds of oxygen a day, so that's the daily requirement for about ten thousand people. Every walk in the forest is like taking a shower in oxygen. But only during the day. Trees manufacture large amounts of carbohydrates not only to lay them down as wood but also to satisfy their hunger. Trees use carbohydrates as fuel, just as we do, and when they do, they convert sugar into energy and carbon dioxide. During the day, this doesn't affect the air much because after all the additions and subtractions, there is still that surplus oxygen I just mentioned. At night, however, the trees don't photosynthesize, and so they don't break down carbon dioxide. Quite the opposite, in fact. In the darkness, it's all about using carbohydrates, burning sugar in the cells' power-generating stations, and releasing carbon dioxide. But don't worry, you won't suffocate if you take a nighttime ramble! A steady movement of air through the forest ensures that all the gases are well mixed at all times, and so the drop in oxygen near the ground is not particularly noticeable.

Breathhold Walking Anders Olsson uses this technique to increase carbon dioxide and, thus, increase circulation in his body. It’s not much fun, but the benefits, Olsson told me, are many. Go to a grassy park, beach, or anywhere else where the ground is soft. Exhale all the breath, then walk slowly, counting each step. Once you feel a powerful sense of air hunger, stop counting and take a few very calm breaths through the nose while still walking. Breathe normally for at least a minute, then repeat the sequence. The more you practice this technique, the higher the count. Olsson’s record is 130 steps; mine is about a third of that. 4-7-8 Breathing This technique, made famous by Dr. Andrew Weil, places the body into a state of deep relaxation. I use it on long flights to help fall asleep. Take a breath in, then exhale through your mouth with a whoosh sound. Close the mouth and inhale quietly through your nose to a mental count of four. Hold for a count of seven. Exhale completely through your mouth, with a whoosh, to the count of eight. Repeat this cycle for at least four breaths.

Carbon dioxide has its own flavor, which affects the overall taste of a drink. (At high partial pressures—which is to say, when a gas contains lots of CO2 relative to other gases—it also sets off the body’s pain receptors, called “nociceptors.” One trick almost every distiller I visited tried to play on me was to get me to stick my head into the vat during the final stages of fermentation, when the headspace—the volume of air above the liquid—is a cloud of CO2. Taking a whiff is like sticking a knitting needle up your nose. Too much of it, and you can pass out and fall right into the vat. Fun!)

Adding carbon dioxide, or any other greenhouse gas, to the atmosphere by, say, burning fossil fuels or leveling forests is, in the language of climate science, an anthropogenic forcing. Since preindustrial times, the concentration of CO2 in the atmosphere has risen by roughly a third, from 280 to 378 parts per million. During the same period, the concentration of methane has more than doubled, from .78 to 1.76 parts per million. Scientists measure forcings in terms of watts per square meter, or w/m2, by which they mean that a certain number of watts have been added (or, in the case of a negative forcing, like aerosols, subtracted) for every single square meter of the earth’s surface. The size of the greenhouse forcing is estimated, at this point, to be 2.5 w/m2. A miniature Christmas light gives off about four tenths of a watt of energy, mostly in the form of heat, so that, in effect (as Sophie supposedly explained to Connor), we have covered the earth with tiny bulbs, six for every square meter. These bulbs are burning twenty-four hours a day, seven days a week, year in and year out. If greenhouse gases were held constant at today’s levels, it is estimated that it would take several decades for the full impact of the forcing that is already in place to be felt. This is because raising the earth’s temperature involves not only warming the air and the surface of the land but also melting sea ice, liquefying glaciers, and, most significant, heating the oceans, all processes that require tremendous amounts of energy. (Imagine trying to thaw a gallon of ice cream or warm a pot of water using an Easy-Bake oven.) The delay that is built into the system is, in a certain sense, fortunate. It enables us, with the help of climate models, to foresee what is coming and therefore to prepare for it. But in another sense it is clearly disastrous, because it allows us to keep adding CO2 to the atmosphere while fobbing the impacts off on our children and grandchildren.

I have a deep thought for you. Science fiction is just beginning to catch up with the Old Testament. See artificial nitrates run off into the rivers and oceans. See carbon dioxide melt the polar ice caps. See the world's mineral reserves dwindle. See war, famine and plague. See barbaric hordes defile the temple of virgins. See wild stallions mount the prairie dogs. I said science fiction but I guess I meant science. Anyway there's some kind of mythical and/or historic circle-thing being completed here. But I keep smiling. I keep telling myself there's nothing to worry about as long as the youth of America knows what's going on. Brains, brawn, good teeth. tallness.

Corporations go to great lengths to employ geniuses: technologists, designers, financial engineers, economists, artists even. I’ve seen it happen,’ he said. ‘But what have they done with them? They channel all that talent and creativity towards humanity’s destruction. Even when it is creative, Eva, capitalism is extractive. In search of shareholder profit, corporations have put these geniuses in charge of extracting the last morsel of value from humans and from the earth, from the minerals in its guts to the life in its oceans. And these brilliant minds have been used to cajole governments into accepting their raids on the planet’s resources by creating markets for them: markets for carbon dioxide and other pollutants – phoney markets controlled by their employers! Unlike the East India Company, the Technostructure does not need its own armies. It owns our states and their armies, because it controls what we think. The dirtier the industry, the richer and more despised, the more its captains have been able to tap into the rivers of debt-derived money to purchase influence and to blunt opposition. Previously they would buy newspapers and set up TV stations; now they employ armies of lobbyists, found think tanks, litter the Internet with their trolls and, of course, direct monumental campaign donations to the chief enablers of our species’ extinction, the politicians.

About 4.6 billion years ago, a great swirl of gas and dust some 15 billion miles across accumulated in space where we are now and began to aggregate. Virtually all of it—99.9 percent of the mass of the solar system—went to make the Sun. Out of the floating material that was left over, two microscopic grains floated close enough together to be joined by electrostatic forces. This was the moment of conception for our planet. All over the inchoate solar system, the same was happening. Colliding dust grains formed larger and larger clumps. Eventually the clumps grew large enough to be called planetesimals. As these endlessly bumped and collided, they fractured or split or recombined in endless random permutations, but in every encounter there was a winner, and some of the winners grew big enough to dominate the orbit around which they traveled. It all happened remarkably quickly. To grow from a tiny cluster of grains to a baby planet some hundreds of miles across is thought to have taken only a few tens of thousands of years. In just 200 million years, possibly less, the Earth was essentially formed, though still molten and subject to constant bombardment from all the debris that remained floating about. At this point, about 4.5 billion years ago, an object the size of Mars crashed into Earth, blowing out enough material to form a companion sphere, the Moon. Within weeks, it is thought, the flung material had reassembled itself into a single clump, and within a year it had formed into the spherical rock that companions us yet. Most of the lunar material, it is thought, came from the Earth’s crust, not its core, which is why the Moon has so little iron while we have a lot. The theory, incidentally, is almost always presented as a recent one, but in fact it was first proposed in the 1940s by Reginald Daly of Harvard. The only recent thing about it is people paying any attention to it. When Earth was only about a third of its eventual size, it was probably already beginning to form an atmosphere, mostly of carbon dioxide, nitrogen, methane, and sulfur. Hardly the sort of stuff that we would associate with life, and yet from this noxious stew life formed. Carbon dioxide is a powerful greenhouse gas. This was a good thing because the Sun was significantly dimmer back then. Had we not had the benefit of a greenhouse effect, the Earth might well have frozen over permanently, and life might never have gotten a toehold. But somehow life did. For the next 500 million years the young Earth continued to be pelted relentlessly by comets, meteorites, and other galactic debris, which brought water to fill the oceans and the components necessary for the successful formation of life. It was a singularly hostile environment and yet somehow life got going. Some tiny bag of chemicals twitched and became animate. We were on our way. Four billion years later people began to wonder how it had all happened. And it is there that our story next takes us.

Compared to cotton, synthetic fibers require a lot less water to produce, but that’s not necessarily a good enough argument for using them, since they have other significant impacts: they are still made of oil, and their production can require a lot of energy. MIT calculated that the global impact of producing polyester alone was somewhere between 706 million metric tons of carbon dioxide, or about what 185 coal-fired power plants emit in a year.2 Samit Chevli, the principal investigator for biomaterials at DuPont, the giant chemical company, has said that it will be hundreds of years before regular polyester degrades.3 Plus, while the chemicals used in production typically aren’t released to the environment, if factories don’t have treatment systems in the last phase of production, they can release antimony, an element that can be harmful to human health, as well as other toxins and heavy metals. Despite having just written a good amount about the impacts associated with the production of synthetic fibers, that’s actually not why I wanted to call attention to your yoga pants and dry-fit sweat-wicking T-shirts, which we wear out to dinner. It is hard for me to leave my fashion critique at the door, but what I actually want to say about synthetic fibers is that they are everywhere—not just in all of our clothes, but literally everywhere: rivers, lakes, oceans, agricultural fields, mountaintops, glaciers. Everywhere. Synthetic fibers, actually, may be one of the most abundant, widespread, and stubborn forms of pollution that we have inadvertently created.

The principal energy sources of our present industrial civilization are the so-called fossil fuels. We burn wood and oil, coal and natural gas, and, in the process, release waste gases, principally CO2, into the air. Consequently, the carbon dioxide content of the Earth’s atmosphere is increasing dramatically. The possibility of a runaway greenhouse effect suggests that we have to be careful: Even a one- or two-degree rise in the global temperature can have catastrophic consequences. In the burning of coal and oil and gasoline, we are also putting sulfuric acid into the atmosphere. Like Venus, our stratosphere even now has a substantial mist of tiny sulfuric acid droplets. Our major cities are polluted with noxious molecules. We do not understand the long-term effects of our course of action. But we have also been perturbing the climate in the opposite sense. For hundreds of thousands of years human beings have been burning and cutting down forests and encouraging domestic animals to graze on and destroy grasslands. Slash-and-burn agriculture, industrial tropical deforestation and overgrazing are rampant today. But forests are darker than grasslands, and grasslands are darker than deserts. As a consequence, the amount of sunlight that is absorbed by the ground has been declining, and by changes in the land use we are lowering the surface temperature of our planet. Might this cooling increase the size of the polar ice cap, which, because it is bright, will reflect still more sunlight from the Earth, further cooling the planet, driving a runaway albedo* effect? Our lovely blue planet, the Earth, is the only home we know. Venus is too hot. Mars is too cold. But the Earth is just right, a heaven for humans. After all, we evolved here. But our congenial climate may be unstable. We are perturbing our poor planet in serious and contradictory ways. Is there any danger of driving the environment of the Earth toward the planetary Hell of Venus or the global ice age of Mars? The simple answer is that nobody knows. The study of the global climate, the comparison of the Earth with other worlds, are subjects in their earliest stages of development. They are fields that are poorly and grudgingly funded. In our ignorance, we continue to push and pull, to pollute the atmosphere and brighten the land, oblivious of the fact that the long-term consequences are largely unknown.

Ocean Acidification is sometimes referred to as Global Warming's Equally Evil Twin. The irony is intentional and fair enough as far as it goes... No single mechanism explains all the mass extinctions in the record and yet changes in ocean chemistry seem to be a pretty good predictor. Ocean Acidification played a role in at least 2 of the Big Five Extinctions: the End-Permian and the End-Triassic. And quite possibly it was a major factor in a third, the End-Cretaceous. ...Why is ocean acidification so dangerous? The question is tough to answer only because the list of reasons is so long. Depending on how tightly organisms are able to regulate their internal chemistry, acidification may affect such basic processes as metabolism, enzyme activity, and protein function. Because it will change the makeup of microbial communities, it will alter the availability of key nutrients, like iron and nitrogen. For similar reasons, it will change the amount of light that passes through the water, and for somewhat different reasons, it will alter the way sound propagates. (In general, acidification is expected to make the seas noisier.) It seems likely to promote the growth of toxic algae. It will impact photosynthesis—many plant species are apt to benefit from elevated CO2 levels—and it will alter the compounds formed by dissolved metals, in some cases in ways that could be poisonous. Of the myriad possible impacts, probably the most significant involves the group of creatures known as calcifiers. (The term calcifier applies to any organism that builds a shell or external skeleton or, in the case of plants, a kind of internal scaffolding out of the mineral calcium carbonate.)... Ocean acidification increases the cost of calcification by reducing the number of carbonate ions available to organisms that build shells or exoskeletons. Imagine trying to build a house while someone keeps stealing your bricks. The more acidified the water, the greater the energy that’s required to complete the necessary steps. At a certain point, the water becomes positively corrosive, and solid calcium carbonate begins to dissolve. This is why the limpets that wander too close to the vents at Castello Aragonese end up with holes in their shells. According to geologists who work in the area, the vents have been spewing carbon dioxide for at least several hundred years, maybe longer. Any mussel or barnacle or keel worm that can adapt to lower pH in a time frame of centuries presumably already would have done so. “You give them generations on generations to survive in these conditions, and yet they’re not there,” Hall-Spencer observed.

About 4.6 billion years ago, a great swirl of gas and dust some 24 billion kilometres across accumulated in space where we are now and began to aggregate. Virtually all of it – 99.9 per cent of the mass of the solar system21 – went to make the Sun. Out of the floating material that was left over, two microscopic grains floated close enough together to be joined by electrostatic forces. This was the moment of conception for our planet. All over the inchoate solar system, the same was happening. Colliding dust grains formed larger and larger clumps. Eventually the clumps grew large enough to be called planetesimals. As these endlessly bumped and collided, they fractured or split or recombined in endless random permutations, but in every encounter there was a winner, and some of the winners grew big enough to dominate the orbit around which they travelled. It all happened remarkably quickly. To grow from a tiny cluster of grains to a baby planet some hundreds of kilometres across is thought to have taken only a few tens of thousands of years. In just 200 million years, possibly less22, the Earth was essentially formed, though still molten and subject to constant bombardment from all the debris that remained floating about. At this point, about 4.4 billion years ago, an object the size of Mars crashed into the Earth, blowing out enough material to form a companion sphere, the Moon. Within weeks, it is thought, the flung material had reassembled itself into a single clump, and within a year it had formed into the spherical rock that companions us yet. Most of the lunar material, it is thought, came from the Earth’s crust, not its core23, which is why the Moon has so little iron while we have a lot. The theory, incidentally, is almost always presented as a recent one, but in fact it was first proposed in the 1940s by Reginald Daly of Harvard24. The only recent thing about it is people paying any attention to it. When the Earth was only about a third of its eventual size, it was probably already beginning to form an atmosphere, mostly of carbon dioxide, nitrogen, methane and sulphur. Hardly the sort of stuff that we would associate with life, and yet from this noxious stew life formed. Carbon dioxide is a powerful greenhouse gas. This was a good thing, because the Sun was significantly dimmer back then. Had we not had the benefit of a greenhouse effect, the Earth might well have frozen over permanently25, and life might never have got a toehold. But somehow life did. For the next 500 million years the young Earth continued to be pelted relentlessly by comets, meteorites and other galactic debris, which brought water to fill the oceans and the components necessary for the successful formation of life. It was a singularly hostile environment, and yet somehow life got going. Some tiny bag of chemicals twitched and became animate. We were on our way. Four billion years later, people began to wonder how it had all happened. And it is there that our story next takes us.

So what then is “climate change”? As the WMO defines it, “climate change refers to a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer).” The important thing to keep in mind here is that the climate changes because it is forced to change. And it is forced to change either by natural forces or by forces introduced by mankind. In other words, the climate varies naturally because of its own complex internal dynamics, but it changes because something forces it to change. The most important natural forces inducing climate change are changes in the earth’s orbit—which change the intensity of the sun’s radiation hitting different parts of the earth, which changes the thermal energy balance of the lower atmosphere, which can change the climate. Climate change, scientists know, can also be triggered by large volcanic eruptions, which can release so many dust particles into the air that they act as an umbrella and shield the earth from some of the sun’s radiation, leading to a cooling period. The climate can be forced to change by natural, massive releases of greenhouses gases from beneath the earth’s surface—gases, like methane, that absorb much more heat than carbon dioxide and lead to a sudden warming period. What is new about this moment in the earth’s history is that the force driving climate change is not a change in the earth’s orbit, not a volcanic eruption, not a sudden natural release of greenhouse gases—but the burning of fossil fuels, the cultivation of rice and livestock, and the burning and clearing of forests by mankind, which together are pumping carbon dioxide, methane, and other heat-trapping gases into the atmosphere a hundred times faster than nature normally does.

So it’s not the sight of stromatolites that makes them exciting. It’s the idea of them – and in this respect they are peerless. Well, imagine it. You are looking at living rocks – quietly functioning replicas of the very first organic structures ever to appear on earth. You are experiencing the world as it was 3.5 billion years ago – more than three-quarters of the way back to the moment of terrestrial creation. Now if that is not an exciting thought, I don’t know what is. As the aforementioned palaeontologist Richard Fortey has put it: ‘This is truly time travelling, and if the world were attuned to its real wonders this sight would be as well-known as the pyramids of Giza.’ Quite right. Stromatolites are rather like corals in that all of their life is on the surface, and that most of what you are looking at is the dead mass of earlier generations. If you peer, you can sometimes see tiny bubbles of oxygen rising in streams from the formations. This is the stromatolite’s only trick and it isn’t much, but it is what made life as we know it possible. The bubbles are produced by primitive algae-like micro-organisms called cyanobacteria, which live on the surface of the rocks – about three billion of them to the square yard, to save you counting – each of them capturing a molecule of carbon dioxide and a tiny beat of energy from the sun and combining them to fuel its unimaginably modest ambitions to exist, to live. The byproduct of this very simple process is the faintest puff of oxygen. But get enough stromatolites respiring away over a long enough period and you can change the world. For two billion years this is all the life there was on earth, but in that time the stromatolites raised the oxygen level in the atmosphere to 20 per cent – enough to allow the development of other, more complex life forms: me, for instance. My gratitude was real. The

May I ask you a question? If you have to hold your breath too long, what is it that makes you desperate to breathe again?” “I’m running out of oxygen, I guess.” “That’s the interesting fact. It isn’t the absence of oxygen. It’s the presence of carbon dioxide. Kind of the same thing, but not exactly. The point is, you could suck up any kind of gas, and as long as it wasn’t carbon dioxide, your brain would be happy. You could have a chest full of nitrogen, no oxygen at all, about to kill you stone dead, and your lungs would say, hey man, we’re cool, no carbon dioxide here, no need for us to start pumping again until we see some. Which they never will, because you’ll never breathe again. Because you’ll never need to. Because you have no carbon dioxide. And so on. So those folks started sniffing nitrogen, but you have to go to the welding shop and the cylinders are too heavy to lift, so then they tried helium from the balloon store, but you needed masks and tubes, and the whole thing still looks weird, so in the end most folks won’t be satisfied with anything less than the old-fashioned bottle of pills and the glass of scotch. Exactly like it used to be. Except it can’t be anymore. Those pills were most likely either Nembutal or Seconal, and both of those substances are tightly controlled now. There’s no way to get them. Except illegally, of course, way down where no one can see you. There are sources. The holy grail. Most of the offers are scams, naturally. Powdered Nembutal from China, and so on. Dissolve in water or fruit juice. Maybe eight or nine hundred bucks for a lethal dose. Some poor desperate soul takes the cash to MoneyGram and sends it off, and then waits at home, anxious and tormented, and never sees any powdered Nembutal from China, because there never was any. The powder in the on-line photograph was talc, and the prescription bottle was for something else entirely. Which I felt was a new low, in the end. They’re preying on the last hopes of suicidal people.
