Methane Quotes

While an elderly man in his mid-eighties looks curiously at a porno site, his grandson asks him from afar, “‘What are you reading, grandpa?’” “‘It’s history, my boy.’” “The grandson comes nearer and exclaims, “‘But this is a porno site, grandpa, naked chicks, sex . . . a lot of sex!’” “‘Well, it’s sex for you, my son, but for me it’s history,’ the old man says with a sigh.” All of people in the cabin burst into laughter. “A stale joke, but a cool one,” added William More, the man who just told the joke. The navigator skillfully guided the flying disc among the dense orange-yellow blanket of clouds in the upper atmosphere that they had just entered. Some of the clouds were touched with a brownish hue at the edges. The rest of the pilots gazed curiously and intently outwards while taking their seats. The flying saucer descended slowly, the navigator’s actions exhibiting confidence. He glanced over at the readings on the monitors below the transparent console: Atmosphere: Dense, 370 miles thick, 98.4% nitrogen, 1.4% methane Temperature on the surface: ‒179°C / ‒290°F Density: 1.88 g/cm³ Gravity: 86% of Earth’s Diameter of the cosmic body: 3200 miles / 5150 km.

Poets say science takes away from the beauty of the stars - mere globs of gas atoms. I too can see the stars on a desert night, and feel them. But do I see less or more? The vastness of the heavens stretches my imagination - stuck on this carousel my little eye can catch one - million - year - old light. A vast pattern - of which I am a part... What is the pattern, or the meaning, or the why? It does not do harm to the mystery to know a little about it. For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of it? What men are poets who can speak of Jupiter if he were a man, but if he is an immense spinning sphere of methane and ammonia must be silent?

You could be different,” Elena said quietly. “You could be great. Greater than me—than any of us.” Celaena opened her mouth, but no words came out. Elena took a step toward her. “You could rattle the stars,” she whispered. “You could do anything, if you only dared. And deep down, you know it, too. That’s what scares you most.” She

The four highest-impact things an individual can do to tackle climate change are eat a plant-based diet, avoid air travel, live car-free, and have fewer children. Of those four actions, only plant-based eating immediately addresses methane and nitrous oxide, the most urgently important greenhouse gases.

In ways that certain of us are uncomfortable about, SNOOTs’ attitudes about contemporary usage resemble religious/political conservatives’ attitudes about contemporary culture. We combine a missionary zeal and a near-neural faith in our beliefs’ importance with a curmudgeonly hell-in-a-handbasket despair at the way English is routinely manhandled and corrupted by supposedly educated people. The Evil is all around us: boners and clunkers and solecistic howlers and bursts of voguish linguistic methane that make any SNOOT’s cheek twitch and forehead darken. A fellow SNOOT I know likes to say that listening to most people’s English feels like watching somebody use a Stradivarius to pound nails: We are the Few, the Proud, the Appalled at Everyone Else.

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.

How I'm rushing through this! How much each sentence in this brief story contains. "The stars are made of the same atoms as the earth." I usually pick one small topic like this to give a lecture on. Poets say science takes away from the beauty of the stars—mere globs of gas atoms. Nothing is "mere." I too can see the stars on a desert night, and feel them. But do I see less or more ? The vastness of the heavens stretches my imagina-tion—stuck on this carousel my little eye can catch one-million-year-old light. A vast pattern—of which I am a part—perhaps my stuff was belched from some forgotten star, as one is belching there. Or see them with the greater eye of Palomar, rushing all apart from some common starting point when they were perhaps all together. What is the pattern, or the meaning, or the why ? It does not do harm to the mystery to know a little about it. For far more marvelous is the truth than any artists of the past imagined! Why do the poets of the present not speak of it ? What men are poets who can speak of Jupiter if he were like a man, but if he is an immense spinning sphere of methane and ammonia must be silent?

Kangaroo farts, as fate would have it, don’t contain methane.

This is an interval, ein Augenblick. The cosmic process is hurrying on, crushing life back into the granite and methane; the wheel turns for all life. It is all temporary. And

What men are poets who can speak of Jupiter if he were like a man, but if he is an immense spinning sphere of methane and ammonia must be silent?

Todd, trust math. As in Matics, Math E. First-order predicate logic. Never fail you. Quantities and their relation. Rates of change. The vital statistics of God or equivalent. When all else fails. When the boulder's slid all the way back to the bottom. When the headless are blaming. When you do not know your way about. You can fall back and regroup around math. Whose truth is deductive truth. Independent of sense or emotionality. The syllogism. The identity. Modus Tollens. Transitivity. Heaven's theme song. The night light on life's dark wall, late at night. Heaven's recipe book. The hydrogen spiral. The methane, ammonia, H2O. Nucleic acids. A and G, T and C. The creeping inevibatility. Caius is mortal. Math is not mortal. What it is is: listen: it's true.

It was a monumental achievement that the serpentine tc'a had once upon a time gotten the knnn to understand the concept of trade: so nowadays knnn simply contacted a station, rushed onto its methane-dock and deposited whatever they liked, grabbed whatever they wanted and left. This was an improvement over their former behavior, in which they simply looted and left.

Because methane is so powerful as a greenhouse gas, let’s phase it out as fast as we practically can, while we absolutely stop burning coal. It’s everything-all-at-once time. Coal, gas, oil … ultimately, they all have to go. The real key for the Next Great Generation will be to build a society that doesn’t need natural gas or fossil fuels of any kind at all.

How about methane? It too is chemically unstable, and yes, some of it is anthropogenic, but as we've seen, methane has nonliving agents as well.

A psychotic world we live in. The madmen are in power. How long have we known this? Faced this?-And-how many of us do know it? Not Lotze. Perhaps if you know you are insane then you are not insane. Or you are becoming sane, finally. Waking up. I suppose only a few are aware of all this. Isolated persons here and there. But the broad masses...what do they think? All these hundreds of thousands in this city, here. Do they imagine that they live in a sane world? Or do they guess, glimpse the truth...? But, he thought, what does it mean, insane? A legal definition. What do I mean? I feel it, see it, but what is it? He thought, it is something they do, something they are. It is their unconsciousness. Their lack of knowledge about others. Their not being aware of what they do to others, the destruction they have caused and are causing. No, he thought. That isn't it. I don't know; I sense it, inuit it. But-they are purposely cruel...is that it? No. God, he thought, I can't find it, make it clear. Do they ignore parts of reality? Yes. But it is more. It is their plans. Yes, their plans. The conquering of the planets. Something frenzied and demented, as was their conquering of Africa, and before that, Europe and Asia. Their view; it is cosmic. Not of man here, a child there, but an abstraction: race, land. Volk. Land. Blut. Ehre. Not of honorable men but of Ehre itself, honor; the abstract is real, the actual is invisible to them. Die Gute, but not good men, this good man. It is their sense of space and time. They see through the here, the now, into the vast black deep beyond, the unchanging. And that is fatal to life. Because eventually there will be no life; there was once only the dust particles in space, the hot hydrogen gases, nothing more, and it will come again. This is an interval, ein Augenblick. The cosmic process is hurrying on, crushing life back into the granite and methane; the wheel turns for all life. It is all temporary. And they-these madmen-respond to the granite, the dust, the longing of the inanimate; they want to aid Natur. And, he thought, I know why. They want to be the agents, not the victims, of history. They identify with God's power and believe they are godlike. That is their basic madness. They are overcome by some archetype; their egos have expanded psychotically so that they cannot tell where they begin and the godhead leaves off. it is not hubris, not pride; it is inflation of the ego to its ultimate-confusion between him who worships and that which is worshiped. Man has not eaten God; God has eaten man. What they do not comprehend is man's helplessness. I am weak, small, of no consequence to the universe. It does not notice me; I live on unseen. But why is that bad? Isn't it better that way? Whom the gods notice they destroy. Be small...and you will escape the jealousy of the great.

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.

We can think of our atmosphere as a budget and our emissions as expenses: because methane and nitrous oxide are significantly larger greenhouse expenses than CO2 in the short term, they are the most urgent to cut. Because they are primarily created by our food choices, they are also easier to cut.

She hated those boys and knew that they were stupid and hence their opinions were baseless and the impact of their lives on the planet would be measured only in undifferentiated emissions of methane and nitrates . . . but still.

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.

Elena took a step toward her. “You could rattle the stars,” she whispered. “You could do anything, if you only dared. And deep down, you know it, too. That’s what scares you most.

Methane emissions are lower in biodiverse pasture systems largely because of fumaric acid – a compound that scientists at the Rowett Institute in Aberdeen identified as leading to faster growth and reducing emissions of methane by 70 per cent when added to the diet of lambs. Fumaric acid occurs widely in many plants and herbs of the field and hedgerow, including angelica, common fumitory, shepherd’s purse and bird’s-foot trefoil.

We need to give you two a couple name,” I said, taking a seat on the opposite side of the table. “Lucsey, perhaps?” Luc didn’t bat an eyelash; he simply turned a page of the newspaper. “Call us what you want, Sentinel. We already have a name for you.” That was alarming. Not that there was a way to avoid it, but I wasn’t sure I wanted them discussing my relationship around the Ops Room table. “No, you don’t.” “Yes, we do.” Lindsey stirred her spoon noisily around the walls of the yogurt cup to get the remaining drops. “You’re Methan.” “We’re what?” “Methan. Merit and Ethan. Methan.

IN 1953, STANLEY Miller, a graduate student at the University of Chicago, took two flasks—one containing a little water to represent a primeval ocean, the other holding a mixture of methane, ammonia, and hydrogen sulphide gases to represent Earth’s early atmosphere—connected them with rubber tubes, and introduced some electrical sparks as a stand-in for lightning. After a few days, the water in the flasks had turned green and yellow in a hearty broth of amino acids, fatty acids, sugars, and other organic compounds. “If God didn’t do it this way,” observed Miller’s delighted supervisor, the Nobel laureate Harold Urey, “He missed a good bet.

What men are poets who can speak of Jupiter if he were like a man, but if he is an immense spinning sphere of methane and ammonia be silent?

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.

The cheapest way to warm Mars may be to use bacteria that convert nitrogen and water into ammonia or that can create methane out of water and carbon dioxide. The

Die Wolkendecke besteht zu gleichen Teilen aus Methan, Ammoniak, Staub und fliegender Scheiße.

Molecules of methane that make their way into the atmosphere create a warming effect up to thirty-four times stronger than carbon dioxide over a one-hundred-year time horizon.

War, building like methane in the chamber of a mine: any day could come the spark.

Fred’s vacuum-rated armor protected him from the smell of viscera, but it reported it to him as a slight increase in atmospheric methane levels. The stench of death reduced to a data point.

there was once only the dust particles in space, the hot hydrogen gases, nothing more, and it will come again. This is an interval, ein Augenblick.

NO DIVINE BOVINE ! The clumsy creature currently inhabiting the White House is a distinctly dangerous animal. Part boneheaded raging bully, part dastardly coward showing signs of advanced stage mad cow disease. Neither of good pedigree nor useful breeding stock, there is essentially very little of substance between the T (bone) and the RUMP, except of course for an abundance of methane and bullshit. It's high time brave matadors for you to enter the bullring, with nimble step and fleet of foot. Take good aim and bring down this marauding beast once and for all. Slay public enemy number one and we will salute you forever. A louder cheer you will not hear from Madrid to Mexico City, from Beijing to Brussels, from London to Lahore, from Toronto to Tehran and ten thousand cities in between.

Each parasaur produced a large mound of straw-colored spoor. This was accompanied by low trumpeting from each animal in the herd—along with an enormous quantity of expelled flatus, redolent of methane.

Their view; it is cosmic. Not of a man here, a child there, but an abstraction: race, land. Volk. Land. Blut. Ehre. Not of honorable men but of Ehre itself, honor; the abstract is real, the actual is invisible to them. Die Güte, but not good men, this good man. It is their sense of space and time. They see through the here, the now, into the vast black deep beyond, the unchanging. And that is fatal to life. Because eventually there will be no life; there was once only the dust particles in space, the hot hydrogen gases, nothing more, and it will come again. This is an interval, ein Augenblick.

And they—these madmen—respond to the granite, the dust, the longing of the inanimate; they want to aid Natur.

The floating water vases of Zenn-La are always empty. The methanic sulfite that causes the water to levitate is poisonous to all known species of flowers. The mystery is then not why they are empty, but why anyone would make such a vase.

When humans took up farming, they became more disruptive still. According to the paleoclimatologist William Ruddiman, the adoption of wet rice cultivation in Asia some five thousand years ago may have released so much methane into the atmosphere from rotting vegetation as to have changed the climate. “A good case can be made,” he suggests, that “the people in the Iron Age and even the late Stone Age had a much greater per-capita impact on the earth’s landscape than the average modern-day person.

Antarctica used to be a jungle. For millions of years it was as lush as Africa. But continental drift and natural climate change froze it over. All those plants died and decomposed. The gases from that decomposition—most notably methane—got trapped in the ice.

Plumes of hot meat and bubbles of trapped gases like methane—along with the air from the lungs of the deceased moles—would periodically rise through the mole crust and erupt volcanically from the surface, a geyser of death blasting mole bodies free of the planet.

Their view; it is cosmic. Not a man here, a child there, but an abstraction: race, land. Volk. Land. Blut. Ehre.

The Bermuda Triangle coughs up myths like a consumptive asthmatic. Missing vessels are blamed on aliens. Atlantis. Time rifts. Ghost ships. Magnetic anomalies. Methane eruptions. People go mad. People lose their minds. Sometimes I think I've been in the Bermuda Triangle my whole life.

Holly wanted to be sure she understood what was being said. “So you’re saying that Shelly is going to light a fart?” “No, Shelly is going to light the fart. He has stored enough methane to power Haven for a year. There hasn’t been a fart like this since the last dwarf tribal gathering.

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.

It is not uncommon for people to prefer to believe the bullshit that global warming is a hoax than to accept the facts that icebergs are melting, floods and droughts are increasing, the Amazon rain forest is disappearing, and dangerous methane gases are bubbling up from the ocean floor all because global temperatures are rising.

A more miserable life is better...believe me..than an existence protected by an organized society...where everything is calculated....where everything is perfect...

American restaurants throw away an estimated six thousand tons of food every day. All that food rotting in landfills contributes to global warming—see, when it decomposes, it releases methane, a greenhouse gas twenty-one times more damaging than carbon dioxide. So no matter what you’re eating or where you’re eating it, be conscious about how hungry you really are.

... The Sirens of Titan …. … ‘That’s a funny name for a book,’ I said with a gulp. ‘Are those women going to get arrested?’ Mr Peterson didn’t know what the hell I was talking about. ‘They’re not wearing many clothes,’ I pointed out. ‘What’s your point?’ he asked. ‘So I thought maybe the sirens might be for them.’ Mr Peterson frowned. ‘ I think the police are allowed to arrest you for wearing too few clothes,’ I explained. Comprehension dawned on Mr Peterson’s face. ‘No, kid. Not sirens as in police sirens. Sirens as in Homer.’ I frowned. ‘Simpson?’ ‘The Odyssey!’ I looked at him blankly. At some point in the last thirty seconds, we’d stopped speaking the same language. Mr Peterson sighed and rubbed his wrinkled forehead. ‘The Odyssey’s a very old Greek story by a very old Greek man called Homer. And in The Odyssey there are these very beautiful women called sirens …… ‘oh’, I said. ‘So the women are the sirens? And that’s why they’re not wearing very many clothes?” ‘Right. Except in Kurt Vonnegut’s book the Sirens don’t live in the Mediterranean. They live on Titan, which is one of Saturn’s moons.’ ‘Yes, I know that,’ I said. (I didn’t want Mr Peterson to think I was an idiot). ‘It’s the second largest moon in the solar system, after Ganymede, Jupiter’s largest moon. It’s actually larger than Mercury, though not nearly so dense.’ Mr Peter frowned again and shook his head. ‘I guess these days school puts a big emphasis on sciences instead of the arts, huh?’ ‘No, not really. School puts a big emphasis on exam questions. Do sirens breathe methane?

Though the question of global warming had not yet emerged to public perception, natural gas—methane—is about thirty times more effective than carbon dioxide as a greenhouse gas. No one has calculated how much the vast waste of natural gas across the decades of the twentieth century—in the United States and throughout the world—contributed to global warming. The percentage was certainly more than zero.

In 1909 Carl Bosch perfected a process invented by Fritz Haber which used methane and steam to pull nitrogen out of the air and turn it into fertilizer on an industrial scale, replacing the massive quantities of bird poop that had previously been needed to return nitrogen to depleted soils. Those two chemists top the list of the 20th-century scientists who saved the greatest number of lives in history, with 2.7 billion.

They see through the here, the now, into the vast black deep beyond, the unchanging. And that is fatal to life. Because eventually there will be no life; there was once only the dust particles in space, the hot hydrogen gases, nothing more, and it will come again. This is an interval, ein Augenblick. The cosmic process is hurrying on, crushing life back into granite and methane; the wheel turns for all life. It is all temporary.

When you look carefully at the infrared spectrum of the Earth, you discover the minor constituents of the air. In addition to water vapor, there’s carbon dioxide (CO2), methane (CH4), and other gases that absorb the heat that the Earth tries to radiate away to space at night. These gases warm the planet. Without them, the Earth would everywhere be below the freezing point of water. You’ve discovered this world’s greenhouse effect.

We are fossil fuel addicts. What happens when drug addicts detox? They can be rash, cranky, even psychotic and dangerous. It would be good for the environment if the entire economy abruptly quit fossil fuels, but that's not realistic. I wouldn't want to be around if it ever happened. Perhaps it's best to think of natural gas like methadone. It's a way for an energy addicted society to get off dirtier fuels and smooth out the detox bumps.

Recovered fracking waste is left in open-air pits to evaporate. This releases volatile organic compounds, creating contaminated air, acid rain, and ground-level ozone. Metal ball bearings are added to fracking fluids to keep the fractures open indefinitely. These toxic chemicals leach out and contaminate nearby groundwater. Drinking-water wells near fracturing sites have been found to contain concentrations of methane seventeen times higher than normal.

Another readily detected biomarker is Earth's sustained level of the molecule methane, two thirds of which is produced by human-related activities...[including] burps and farts of domestic livestock. Natural sources...include decomposing vegetation in wetlands, and termite effluences. At this very moment, astrobiologists are arguing over the exact origin of...the copious quantities of methane on Saturn's moon Titan, where cows and termites we presume do not dwell.

A smell is, after all, a violation of oxygen balance, an invasion into it of other elements--methane? carbon? sulphur? nitrogen? Depending on that invasion's intensity, you get a scent, a smell, a stench. It is a molecular affair, and happiness, I suppose, is the moment of spotting the elements of your own composition being free. There were quite a number of them out there, in a state of total freedom, and I felt I'd stepped into my own self-portrait in the cold air.

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.

To her surprise, Jack didn’t seem at all fazed by all the exotic ideas she had had and wanted to try.  She detailed them out, from a small single-story greenhouse that incorporated rabbit hutches to an extensive two-story generator-powered setup with pigs, cows, and chickens on the upper story, their excrement washed down through gunnels by a sprinkler system where it hit a vat, fermented, created methane to run the generator, and then was fed through a hydroponics system directly to the roots of the plants she was trying to grow.

So we now know the formula for extinction. Something happens to increase global temperatures five to six degrees, which triggers a melting of the frozen carbon and methane oceanic reserves that then leads to further global warming devastating life on Earth. Thus, the pressing question for us today is this: Can seven billion people on the planet burning fossil fuels imitate the sort of carbon greenhouse gas release caused by the Permian lava flows, or the K/T mass extinction impact or whatever warming caused the PETM? The answer is yes.

Here's my bright idea for life on earth: better management. The CEO has lost touch with the details. I'm worth as much, but I care; I come down here, I show my face, I'm a real regular. A toast: To our boys and girls in the war, grinding through sand, to everybody here, our host who's mostly mist, like methane rising from retreating ice shelves. Put me in command. For every town, we'll have a marching band. For each thoroughbred, a comfortable stable; for each worker, a place beneath the table. For every forward step a stumbling. A shadow over every starlit thing.

Europe now has more than thirty receiving terminals for LNG, which can be ramped up on short notice. They are also part of an increasingly dense global network. Worldwide, over forty countries now import LNG, compared to just eleven in 2000. Exporting countries have increased from twelve to twenty. Overall global LNG demand in 2019 was almost four times larger than in 2000, and liquefaction capacity is expected to increase by another 30 percent over the next half decade. Methane molecules from a growing number of countries now jostle and compete with one another for customers across the globe.

According to the UN, the livestock sector is responsible for 18 percent of greenhouse gas emissions, around 40 percent more than the entire transport sector — cars, trucks, planes, trains, and ships — combined. Animal agriculture is responsible for 37 percent of anthropogenic methane, which offers twenty-three times the global warming potential (GWP) of CO2, as well as 65 percent of anthropogenic nitrous oxide, which provides a staggering 296 times the GWP of CO2. The most current data even quantifies the role of diet: omnivores contribute seven times the volume of greenhouse gases that vegans do.

It is—their unconsciousness. Their lack of knowledge about others. Their not being aware of what they do to others, the destruction they have caused and are causing. [...] Do they ignore parts of reality? Yes. But it is more. It is their plans. Yes, their plans. The conquering of the planets. Something frenzied and demented, as was their conquering of Africa, and before that, Europe and Asia. Their view; it is cosmic. Not of a man here, a child there, but an abstraction: race, land. Volk. Land. Blut. Ehre. Not of honorable men but of Ehre itself, honor; the abstract is real, the actual is invisible to them. Die Güte, but not good men, this good man. It is their sense of space and time. They see through the here, the now, into the vast black deep beyond, the unchanging. And that is fatal to life. Because eventually there will be no life; there was once only the dust particles in space, the hot hydrogen gases, nothing more, and it will come again. This is an interval, ein Augenblick. The cosmic process is hurrying on, crushing life back into the granite and methane; the wheel turns for all life. It is all temporary. And they—these madmen—respond to the granite, the dust, the longing of the inanimate; they want to aid Natur. […] They want to be the agents, not the victims, of history.

Imagine walking under a glowing violet sky, where great flashing clouds sweep the earth with shadow and rain strides beneath them. Imagine walking on the slopes of a mountain like polished metal, with a clean red flame exploding above you and thunder laughing in the ground. Imagine a cool wild stream, and low trees with dark coppery flowers, and a waterfall, methane-fall...whatever you like, leaping off a cliff, and the strong live wind shakes its mane full of rainbows! Imagine a whole forest, dark and breathing, and here and there you glimpse a pale-red wavering will-o'-the-wisp, which is the life radiation of some fleet shy animal, and...and-

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.

Maybe that's where it started and they brought it back from the desert, some kind of contagious psychic wound, guilt based. Maybe it's the dark matter, invisibly making up most of the universe. Maybe it was methane thawing at the bottom of the sea, releasing some ancient spore from the melted icebergs. Maybe it was the hole in the ozone, the collapse of the upper atmosphere. Maybe it was the overload of information, the swarms of data generated by every human gesture. Maybe it was the networking craze, the resurrection of dead friendships and memories meant to be lost, now resurfacing like rusted shipwrecks to reclaim our attention and scramble our sense of time. Maybe it was the death of an artist at the hands of a zealot. Maybe it was the particles made to collide. Maybe the mapping of the genome. Maybe the clashing of gods, the tug-of-war over our souls, not one of them refusing to let go, instead opting to see us sliced in two by Soloman's sword. Maybe it was food becoming a prop for food. Maybe it was a distant comet dusting us with its tail of poisoned ice. Maybe it was someone uttering a combination of syllables that should never be uttered. Maybe it was the emergence of collective intelligence, the flattening of the world. Maybe the game we inhabit had a glitch. Maybe the angel's horn had finally been blown.

Organic farming is environmentally friendlier to every acre of land. But it requires _more_ acres. The trade-off is a harsh one. Would we rather have pesticides on farmland and nitrogen runoffs from them? Or would we rather chop down more forest? How much more forest would we have to chop down? If we wanted to reduce pesticide use and nitrogen runoff by turning all of the world’s farmland to organic farming, we’d need about 50 percent more farmland than we have today. Nobel Prize winner Norman Borlaug, whose work helped triple crop yields over the last fifty years and arguably saved billions from starvation, estimates that the world would need an _additional_ 5 to 6 billion head of cattle to produce enough manure to fertilize that farmland. There are only an estimated 1.3 billion cattle on the planet today. Combined, we’d need to chop down roughly half of the world’s remaining forest to grow crops and to graze cattle that produce enough manure to fertilize those crops. Clearing that much land would produce around 500 billion tons of CO2, or almost as much as the total cumulative CO2 emissions of the world thus far. And the cattle needed to fertilize that land would produce far _more_ greenhouse gases, in the form of methane, than all of agriculture does today, possibly enough to equal all human greenhouse gases emitted from all sources today. That’s not a viable path.

Science fiction didn’t see the mobile phone coming. It certainly didn’t see the glowing glass windows many of us carry now, where we make things amazing happen by pointing at it with our fingers like goddamn wizards. That, by the way, is what Steve Jobs meant when he said that iPads were magical. The central metaphor is magic. And perhaps magic seems an odd thing to bring up here, but magic and fiction are deeply entangled, and you are all now present at a séance for the future. We are summoning it into the present. It’s here right now. It’s in the room with us. We live in the future. We live in the Science Fiction Condition, where we can see under atoms and across the world and across the methane lakes of Titan.

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.

Life, a miracle of nature, an evolved molecule of matter, blossomed in the vast expanse of oceans. Methane, ammonia, hydrogen and water vapor When joined under the radio-active sun, The molecules of non living matter underwent massive changes and became live. It's this accident that made the molecule of protein, Which even Stanley Miller reproduced in lab. Evolution went on, and on and changed , from amoeba to dinosaurs, from ape to man, It was an amazing architecture of nature , Which still continue improving human brain. The amazing creation nature, the man, kept on exploring the mysteries of nature, and succeeded in duplicating nature's marvel through his latest invention - the cloning, and succeeded in decoding even the genetic code. Still we have to salute the mother nature, which has many more mysteries in store!.

Had your spacecraft flown by the Earth a hundred million years ago, in the age of the dinosaurs when there were no humans and no technology, you would still have seen oxygen and ozone, the chlorophyll pigment, and far too much methane. At present, though, your instruments are finding signs not just of life, but of high technology—something that couldn’t possibly have been detected even a hundred years ago: You are detecting a particular kind of radio wave emanating from Earth. Radio waves don’t necessarily signify life and intelligence. Many natural processes generate them. You’ve already found radio emissions from other, apparently uninhabited worlds—generated by electrons trapped in the strong magnetic fields of planets, by chaotic motions at the shock front that separates these magnetic fields from the interplanetary magnetic field, and by lightning.

I am bought, she thinks. I am paid for. I am bought. When she first arrived at the Environment Ministry as Akkarat's mole, it was a surprise to discover that the little privileges of the Environment Ministry were always enough. The weekly take from street stalls to burn something other than expensive approved-source methane. The pleasure of a night patrol spent sleeping well. It was an easy existence. Even under Jaidee, it was easy. And now by ill-luck she must work, and the work is important, and she has had two masters for so long that she cannot remember which one should be ascendant. Someone else should have replaced you, Jaidee. Someone worthy. The Kingdom falls because we are not strong. We are not virtuous, we do not follow the eightfold path and now the sicknesses come again. And she is the one who must stand against them, like Phra Seub—but without the strength or moral compass.

•  The four highest-impact things an individual can do to tackle climate change are eat a plant-based diet, avoid air travel, live car-free, and have fewer children. •  Of those four actions, only plant-based eating immediately addresses methane and nitrous oxide, the most urgently important greenhouse gases. •  Most people are not in the process of deciding whether to have a baby. •  Eighty-five percent of Americans drive to work. Few drivers can simply decide to stop using their cars. •  For Americans, 29 percent of air travel in 2017 was for business purposes, and 21 percent was for “personal non-leisure purposes.” Businesses must rely more on remote communication, “personal non-leisure” flights must be reduced, and personal leisure flights can and must be cut, but the fact remains that a sizable portion of air travel is unavoidable. •  Everyone will eat a meal relatively soon and can immediately participate in the reversal of climate change.

The world’s most celebrated religions teach people that the world around us, our environment, is sacred. A diet rooted in anymal products is exponentially more harmful to the earth than is a plant-based diet. Seventy percent more land must be cultivated in order to raise anymals for food than would be necessary for a vegan diet. This means that 70 percent more land is taken away from natural ecosystems to produce flesh, nursing milk, and bird’s reproductive eggs for consumption, and this land that is necessary for a diet rich in anymal products will be sprayed with pesticides and earth-damaging fertilizers. These additional crops—70 percent more—also need to be irrigated, using exponentially more water. Anymals exploited by food industries also drink millions of gallons of water and drop millions of tons of manure. Finally, raising animals for flesh contributes significantly to carbon dioxide, nitrous oxides, chlorofluorocarbons, and methane—global climate change.

Seymour studies the quantities of methane locked in melting Siberian permafrost. Reading about declining owl populations led him to deforestation which led to soil erosion which led to ocean pollution which led to coral bleaching, everything warming, melting, and dying faster than scientists predicted, every system on the planet connected by countless invisible threads to every other: cricket players in Delhi vomiting from Chinese air pollution, Indonesian peat fires pushing billions of tons of carbon into the atmosphere over California, million-acre bushfires in Australia turning what’s left of New Zealand’s glaciers pink. A warmer planet = more water vapor in the atmosphere = even warmer planet = more water vapor = warmer planet still = thawing permafrost = more carbon and methane trapped in that permafrost releasing into the atmosphere = more heat = less permafrost = less polar ice to reflect the sun’s energy, and all this evidence, all these studies are sitting there in the library for anybody to find, but as far as Seymour can tell, he’s the only one looking.

Deep underground, microbes turn half a century's worth of city waste into methane. The gases and leachate are extracted through an extensive network of subterranean pipes and then used to power 22,000 nearby homes. While 150 million tons of garbage gradually decomposes unseen below the surface, above ground, the former dump reverts to meadows, woodland and saltwater marshes, providing a haven for wildlife and a massive park for the people of New York. This is Fresh Kills in the 2020s. In 2001, the infamous landfill received its last, and saddest, consignments - the charred debris of the World Trade Center. Since then, it has been transformed into a 2,315-acre public park. Three times bigger than Central Park, it is the largest new green public space created within New York City for over a century, a mixture of wildlife habitats, bike trails, sports fields, art exhibits and playgrounds. This is poisoned land: fifty years' worth of landfill has killed for ever one of the city's most productive wetland ecosystems. Restoration is impossible. Instead, a brand new ecosystem is emerging on top of the toxic garbage

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.

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.

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.

For unknown ages after the explosive outpouring of matter and energy of the Big Bang, the Cosmos was without form. There were no galaxies, no planets, no life. Deep, impenetrable darkness was everywhere, hydrogen atoms in the void. Here and there, denser accumulations of gas were imperceptibly growing, globes of matter were condensing-hydrogen raindrops more massive than suns. Within these globes of gas was kindled the nuclear fire latent in matter. A first generation of stars was born, flooding the Cosmos with light. There were in those times, not yet any planets to receive the light, no living creatures to admire the radiance of the heavens. Deep in the stellar furnaces, the alchemy of nuclear fusion created heavy elements from the ashes of hydrogen burning, the atomic building blocks of future planets and lifeforms. Massive stars soon exhausted their stores of nuclear fuel. Rocked by colossal explosions, they returned most of their substance back into the thin gas from which they had once condensed. Here in the dark lush clouds between the stars, new raindrops made of many elements were forming, later generation of stars being born. Nearby, smaller raindrops grew, bodies far too little to ignite the nuclear fire, droplets in the interstellar mist on their way to form planets. Among them was a small world of stone and iron, the early Earth. Congealing and warming, the Earth released methane, ammonia, water and hydrogen gases that had been trapped within, forming the primitive atmosphere and the first oceans. Starlight from the Sun bathed and warmed the primeval Earth, drove storms, generated lightning and thunder. Volcanoes overflowed with lava. These processes disrupted molecules of the primitive atmosphere; the fragments fell back together into more and more complex forms, which dissolved into the early oceans. After a while the seas achieved the consistency of a warm, dilute soup. Molecules were organized, and complex chemical reactions driven, on the surface of clay. And one day a molecule arose that quite by accident was able to make crude copies of itself out of the other molecules in the broth. As time passed, more elaborate and more accurate self replicating molecules arose. Those combinations best suited to further replication were favored by the sieve of natural selection. Those that copied better produced more copies. And the primitive oceanic broth gradually grew thin as it was consumed by and transformed into complex condensations of self replicating organic molecules. Gradually, imperceptibly, life had begun. Single-celled plants evolved, and life began generating its own food. Photosynthesis transformed the atmosphere. Sex was invented. Once free living forms bonded together to make a complex cell with specialized functions. Chemical receptors evolved, and the Cosmos could taste and smell. One celled organisms evolved into multicellular colonies, elaborating their various parts into specialized organ systems. Eyes and ears evolved, and now the Cosmos could see and hear. Plants and animals discovered that land could support life. Organisms buzzed, crawled, scuttled, lumbered, glided, flapped, shimmied, climbed and soared. Colossal beasts thundered through steaming jungles. Small creatures emerged, born live instead of in hard-shelled containers, with a fluid like the early ocean coursing through their veins. They survived by swiftness and cunning. And then, only a moment ago, some small arboreal animals scampered down from the trees. They became upright and taught themselves the use of tools, domesticated other animals, plants and fire, and devised language. The ash of stellar alchemy was now emerging into consciousness. At an ever-accelerating pace, it invented writing, cities, art and science, and sent spaceships to the planets and the stars. These are some of the things that hydrogen atoms do, given fifteen billion years of cosmic evolution.

To make matters even worse, Texas is also the leading producer of cattle in the country. As a result, greenhouse gas emissions, or carbon dioxide, released during the agriculture process is higher in Texas than any other state. Research has also found that the methane released from cow belches is another factor that’s contributing to global warming.

There’s a little canyon in the park where so much methane gas is produced naturally out of the ground that any living thing that wanders into it will die within minutes. The floor of the canyon is covered in elk and bison bones, and maybe even some old Indian bones.” He’d softened his voice and she found it oddly rhythmic. She felt a chill ripple through her. “But when you look at that white patch,” he said, “I want you to imagine something else. Imagine most of Yellowstone Park itself is that white patch. There’s a real thin crust covering hell itself, which is trying to boil over. That wants to boil over. And someday, it will. It’s known as the Yellowstone Caldera. In fact, darlin’, when it blows it’ll take two million people with it. It’s blown a few times through history, and we’re sixty thousand years overdue.

It is as if chemists called any compound that contained carbon—from diamond to methane to methamphetamine—carbon.

In February 1959, the Journal of Commerce, in a story headlined “Cargo Ship with Methane on High Seas,” announced that a converted World War II freighter, renamed the Methane Pioneer, had set sail from Louisiana for England. It carried a cargo that had never before been shipped over the seas—liquefied natural gas—LNG. Liquefied natural gas is the product of a complex process that refrigerates natural gas to extreme cold, down to minus 260 degrees Fahrenheit, thus compressing it into a liquid. Since in its liquid form the gas takes up only one six-hundredth of the space that it would in its gaseous state, it can be pumped into tanks on refrigerated ships and transported across oceans and then “regasified”—turned back into gas—at the other end and pumped into a pipeline system in the receiving country.

Water vapor and clouds account for about 90 percent of the Earth’s natural greenhouse effect, CO2 amounts to about 3.5 percent, and methane contributes even less.

It turns out the amount of methane produced by a given cow depends a lot on where the cow lives; for example, cattle in South America emit up to five times more greenhouse gases than ones in North America do, and African cattle emit even more. If a cow is being raised in North America or Europe, it’s more likely to be an improved breed that converts feed into milk and meat more efficiently. It will also get better veterinary care and higher-quality feed, which means it’ll produce less methane.

On long timescales, increases in temperature, controlled by the Earth’s orbit around the sun, create more methane and carbon dioxide. That’s right: from what most scientists can tell, greenhouse gases are not the primary driver of long-term climate change on Earth—Milankovitch’s orbital variations are. Still, everything about climate is complex, and it’s quite possible that greenhouse gases can help trigger changes at particular times, or they can help exaggerate feedback processes already underway on Earth. But it’s the orbital variations of the Earth around the sun—the three major interacting Milankovitch cycles—that give the general form to the ups and downs on the temperature plot in figure 11.2. Greenhouse gases and many other variables on Earth simply follow those ups and downs in temperature.

Realization 4. News from field climatologists will keep getting worse. When one positive feedback—such as a “gigaburp” of methane released from melting permafrost—takes off conspicuously, a sense of public emergency will take off with it. Already temperatures in the Arctic have gone up over 4°C since 1950. The suddenness of a self-accelerating phenomenon invites proportionally immediate response.

Another bizarre event occurred 55 million years ago, when a trillion tons of methane burped out of the oceans from thawing methane hydrates (also called clathrates) on the sea floor. The sudden temperature rise of 8°C (14.5°F) extinguished two thirds of oceanic species and was nearly as catastrophic on land as the dinosaur-killing asteroid 10 million years earlier.

Zealand, which is in the Mars Time Zone, but we were unable to locate any of the people named in the exploding cow story. We were actually starting to wonder if the Sun story was untrue when suddenly, without warning, an alert reader named Donald McEwan sent us another frightening cow-related news item. This one came from the Washington Post, and it stated—we are not making any of this up—that a Colorado State University animal-nutrition professor named Donald Johnson has been studying cow flatulence for 20 years, and has determined that the average cow emits 200 to 400 quarts of methane per day, resulting in a total annual world cow methane output of 50 million metric tons.

The recent science has looked more closely at the implications of all greenhouse gases not being the same. There is more explicit recognition that zero net emissions can be achieved through a combination of zero emissions for long-lived gases (carbon dioxide) and stable emissions for short-lived gases (methane).

Two Cornell professors, Robert Howarth and Tony Ingraffea, produced a series of elegant papers showing that if even a small percentage of fracked gas leaked, maybe as little as 3 percent, then it would do more climate damage than coal. And their preliminary data showed that leak rates could be at least that high—that between the fracking operations and the thousands of miles of pipes and the compressor stations, somewhere between 3.6 and 7.9 percent of methane gas from shale-drilling operations actually escapes into the atmosphere.

15 million years ago ice sheets began forming over Greenland, and by the beginning of the Quaternary the cooling had passed the threshold for the North Pole’s ice cap to begin expanding. We entered the current phase of pulsing ice ages.23 It seems the Earth has been committed to a concerted effort towards cooling down. What grand-scale planetary processes have been conspiring to drive this global chilling? Gases like carbon dioxide and methane, as well as water vapour, in the atmosphere act like the panes of glass in a greenhouse: they allow the short-wavelength visible sunlight to shine right through and heat the Earth, but block the longer-wavelength infrared light given off by the warm planet surface. The effect of these greenhouse gases is to trap heat energy from escaping back into space, and so insulate the planet, leading to higher temperatures. Any mechanism that reduces the amount of these greenhouse gases in the air will therefore drive a global cooling.

Around the world, there are roughly a billion cattle raised for beef and dairy. The methane they burp and fart out every year has the same warming effect as 2 billion tons of carbon dioxide, accounting for about 4 percent of all global emissions.

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.

Daily, Mom applied hairspray to her stylish hairdo. I remember the smell and the sound of the chemicals invading her ears, nose, and throat, and mine too since I loved to hang out with her. This era marked the start of the consumer use of chlorofluorocarbon (CFC), an organic compound produced as a volatile derivative of methane and ethane that affects the ozone layer of our Earth. These applications of toxins kept Mom’s hair in place until her next appointment. The CFCs from the new aerosol sprays undoubtedly contributed to my sweet mama’s subsequent poor health. But she didn’t stop using hairspray until she went bald from chemotherapy. The United States banned Chlorofluorocarbons in 1978.

Understanding how the climate system responds to human influences is, unfortunately, a lot like trying to understand the connection between human nutrition and weight loss, a subject famously unsettled to this day. Imagine an experiment where we fed someone an extra half cucumber each day. That would be about an extra twenty calories, a 1 percent increase to the average 2,000-calorie daily adult diet. We’d let that go on for a year and see how much weight they gained. Of course, we would need to know many other things to draw any meaningful conclusions from the results: What else did they eat? How much did they exercise? Were there any changes in health or hormones that affect the rate at which they burn calories? Many things would have to be measured precisely to understand the effect of the additional cucumbers, although we would expect that, all else being equal, the added calories would add some weight. The problem with human-caused carbon dioxide and the climate is that, as in the cucumber experiment, all else isn’t necessarily equal, as there are other influences (forcings) on the climate, both human and natural, that can confuse the picture. Among the other human influences on the climate are methane emissions into the atmosphere (from fossil fuels, but more importantly from agriculture) and other minor gases that together exert a warming influence almost as great as that of human-caused CO2.

But there are several important differences between methane and carbon dioxide. One is that methane concentrations are much lower (2,000 parts per billion, which is about 1/200th that of CO2’s 400 parts per million). Another difference is that a methane molecule lasts in the atmosphere for only about twelve years—though after that, chemical reactions covert it to CO2. And a third difference is that, because of the peculiarities of how molecules interact with the different colors of infrared radiation, every additional methane molecule in the atmosphere is thirty times more potent in warming than a molecule of carbon dioxide. These differences—lower concentration and shorter lifetime, but greater warming potency—must be taken into account when comparing CH4 and CO2 emissions. For instance, the 300 million tons of methane humans emit each year is only 0.8 percent of the 36 gigatons of CO2 emitted by burning fossil fuels.

One additional point about methane that surprises many people is that fossil fuels account for only about one quarter of global human-caused methane emissions, as shown in Figure 3.5. Rather, most methane emissions arise from enteric fermentation (digestion in cattle—mostly emitted from the front of the animal, not the back) and other agricultural activities, particularly rice cultivation; the decay of material in landfills is also significant. So any effort to drastically reduce emissions must also address those sources.

The most significant human-caused greenhouse gases influencing the climate are carbon dioxide (CO2) and methane (CH4). Their concentrations in the atmosphere are increasing because we’re emitting them; that’s why efforts to reduce human influences on the climate focus on reducing emissions.

Methane, the second most important human-caused greenhouse gas, has also been increasing over the past century and so also exerts a growing warming influence on the climate.

The most common of the gases making up the earth’s atmosphere are nitrogen (78 percent) and oxygen (21 percent). Combined, then, these two account for 99 percent of the dry atmosphere, and because of the peculiarities of molecular structure, heat passes through them easily. The largest part of the remaining 1 percent is the inert gas argon. But while even less abundant, some of the other gases—most significantly water vapor, carbon dioxide, methane, nitrous oxide, and ozone—intercept, on average, about 83 percent of the heat emitted by the earth’s surface.8 So the earth does indeed emit energy equivalent to what it absorbs from the sun, but instead of directly flowing off into space, cooling our planet to a chilly average of 0ºF, much of that energy is intercepted by the atmosphere blanketing us.
