Grief is an element. It has its own cycle like the carbon cycle, the nitrogen. It never diminishes not ever. It passes in and out of everything.
Peter Heller (The Dog Stars)
Gansey appeared beside Blue in the doorway. He shook his empty bottle at her. "Fair trade," he told her in a way that indicated he had selected a fair-trade coffee beverage entirely so that he could tell Blue that he had selected a fair-trade coffee beverage so that she could tell him well done with your carbon footprint and all that jazz. Blue said, "Better recycle that bottle.
Maggie Stiefvater (The Dream Thieves (The Raven Cycle, #2))
Almost every particle in the universe was once part of a star,” she says softly. “Every atom in your body. The metal in your chair, the oxygen in your lungs, the carbon in your bones. All those atoms were forged in a cosmic furnace over a million kilometers wide, billions of light-years from here. The confluence of events that led to this moment is so remote as to be almost impossible.” She puts her hand on my shoulder. Her touch is awkward, as if she doesn’t quite know how to do it. But she squeezes gently. “Our very existence is a miracle.
Amie Kaufman (Aurora Rising (The Aurora Cycle, #1))
The essential fact which emerges ... is that the three smallest and most active reservoirs ( of carbon in the global carbon cycle), the atmosphere, the plants and the soil, are all of roughly the same size. This means that large human disturbance of any one of these reservoirs will have large effects on all three. We cannot hope either to understand or to manage the carbon in the atmosphere unless we understand and manage the trees and the soil too.
Freeman Dyson (FROM EROS TO GAIA)
I want to end my life like a human being: in Intensive Care, high on morphine, surrounded by cripplingly expensive doctors and brutal, relentless life-support machines. Then the corpse can go into orbit—preferably around the sun. I don't care how much it costs, just so long as I don't end up party of any fucking natural cycle: carbon, phosphorus, nitrogen. Gaia, I divorce thee. Go suck the nutrients out of someone else, you grasping bitch.
Greg Egan (Axiomatic)
I think all you can say,” Saltzman said, “is that when there are severe, rapid changes in the carbon cycle, it doesn’t end well.
Peter Brannen (The Ends of the World: Volcanic Apocalypses, Lethal Oceans, and Our Quest to Understand Earth's Past Mass Extinctions)
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.
J.G. Ballard (The Drowned World)
Drunk one night, Sarah had told me Women are the race, Tak. No two ways about it. Male is just a mutation with more muscle and half the nerves. Fighting, fucking machines. My own cross-sleevings had born that theory out. To be a woman was a sensory experience beyond the male. Touch and texture ran deeper, an interface with environment that male flesh seemed to seal out instinctively. To a man, skin was a barrier, a protection. To a woman, it was an organ of contact. That had its disadvantages. In general, and maybe because of this, female pain thresholds ran higher than male, but the menstrual cycle dragged them down to an all-time low once a month.
Richard K. Morgan (Altered Carbon (Takeshi Kovacs, #1))
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.
David Easton (The Rammed Earth House)
We have altered the Earth system physically and chemically through disrupting the global cycling of carbon, causing warming of the surface of the Earth and acidification of the oceans; and biologically, through species extinctions and the movement of many species to new locations. Of these myriad changes, summarized in Figure 8.1, some are being preserved in geological archives, including glacier ice and sediments accumulating on the ocean floor.
Simon L. Lewis (The Human Planet: How We Created the Anthropocene)
Most of the earth's land is not conducive to arable cropping. Only a tiny percentage is good enough for that. Grasslands are literally the lungs of the earth, and restoring them with animals is not only necessary, but it's the most efficacious way to restore water cycles and the carbon cycle. Right now, nothing else comes close to remediating broken ecological systems as quickly or completely as restoring large herds of grazing animals through holistic, or long-term, management.
Joel Salatin (The Marvelous Pigness of Pigs: Respecting and Caring for All God's Creation)
Who do we think we are — we small creatures with three-pound brains, a few limited senses, and life spans barely long enough to get to know our neighborhood, much less the planet, and much less the galaxy, and much less the universe, and much less still its creator! Who do we think we are to be able to define or even describe the creator of DNA, galaxies, dust mites, blue whales, the carbon cycle, light, and a billion other realities we have no notion about whatsoever, no awareness of at all?
Brian D. McLaren (A Search for What Makes Sense: Finding Faith)
By planting rye I am creating carbon sinks in my backyard, expanding my role in the carbon cycle, launching my own backyard campaign to offset global warming. My emissions, after all, reflect a rural but very comfortable life in which I enjoy goods that travel great distances - clementines from Spain, wine from California - and on the occasional holiday I fly south, seeking warmer places. Will planting rye in the shoulder seasons be enough to make a difference? Certainly not, but it is a gesture, a way to frame the question and provide a benchmark to judge the extent of my complicity.
Amy Seidl (Early Spring: An Ecologist and Her Children Wake to a Warming World)
Limestone is usually formed of the compressed bodies of marine organisms – crinoids and coccolithophores, ammonites, belemnites and foraminifera-- that died in waters of ancient seas and then settled in their trillions on those seabeds. These creatures once built their skeletons and shells out of calcium carbonate, metabolizing the mineral content of the water in which they lived to create intricate architectures. In this way limestone can be seen as merely one phase in a dynamic earth cycle, whereby mineral becomes animal becomes rock; rock that will in time – in deep time – eventually supply the calcium carbonate out of which new organisms will build their bodies, thereby re-nourishing the same cycle into being again.
Robert Macfarlane (Underland: A Deep Time Journey)
There's an old saying: if something's too cheap, somebody is paying. Maher's workers earn $120 to $140 per month to work six days a week-low wages not only globally, but by Bangladesh's standards-to do jobs that are made more stressful with each acceleration of the fast-fashion cycle. Outside of factory gates, those workers endure environmental consequences of a nation cutting corners to keep its industries competitive. The air in Narayanganj, once known as the 'Dandy of the East," is typically an odorous grey-brown and sometimes makes foreign visitors nauseous-the city is one of those where blue skies appeared like a miracle during the coronavirus lockdowns. Bangladesh is one of the nations hardest hit by climate change, although carbon emissions per person there are radically lower than in richer nations.

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.
James Nestor (Breath: The New Science of a Lost Art)
I live here on the Prade Ranch alone-already years beyond the age my mother was when she returned to the ranch-to the particular elements of the earth: soil, water, carbon sky. You can rot or you can burn but either way, if you're lucky, a place will shape and cut and bend you, will strengthen you and weaken you. You trade your life for the privilege of this experience-the joy of a place, the joy of blood family; the joy of knowledge gotten by listening and observing. For most of us, we get stronger slowly, and then get weaker slowly, with our cycles sometimes in synchrony with the land's health, though other times independent of its larger cycles. We watch and listen and notice as the land, the place -life- begins to summon its due from us. It's so subtle...a trace of energy departing here, a trace of impulse missing there. You find yourself as you have always been, square in the middle of the metamorphosis, constantly living and dying: becoming weaker in your strength, finally. Perhaps you notice the soil, the rocks, or the river, taking back some of that which it has loaned to you; or perhaps you see the regeneration occurring in your daughter, if you have one, as she walks around, growing stonger. And you feel for the fir time a sweet absence...
Rick Bass
Greenhouse gases, like carbon dioxide, absorb infrared energy and help warm the planet. So they're absolutely crucial. The problem is that their concentration in the atmosphere needs to be regulated as the sun slowly brightens. Otherwise, the Earth would not be able to stabilize its surface temperature, which would be disastrous. Plate tectonics cycles fragments of the Earth's crust -- including limestone, which is made up of calcium, carbon dioxide, and oxygen atoms -- down into the mantle. There, the planet's internal heat releases the carbon dioxide, which is then continually vented to the atmosphere through volcanoes. It's quite an elaborate process, but the end result is a kind of thermostat that keeps the greenhouse gases in balance and our surface temperature under control. --Guillermo Gonzalez, Ph.D. (astronomer & physicist)
Lee Strobel (The Case for a Creator: A Journalist Investigates Scientific Evidence That Points Toward God)
EXCITED was not the right word. Stevie NEEDED to go back and she WANTED to go back, but the accompanying emotion was anxiety. Anxiety and excitement are cousins; they can be mistaken for each other at points. They have many features in common - the bubbling, carbonated feel of the emotion the speed, the wide eyes and racing heart. But where excitement tends to take you up, into the higher, brighter levels of feeling, anxiety pulls you down, making you feel like you have to grip the earth to keep from sliding off as it turns. This was the sympathetic nervous system at work, her therapist had told her. To work with anxiety, you had to let it complete its cycle. Steve tapped her foot against the SUV floor, telling the cycle to get a movie on. What was she anxious about? Going back to the case, going back to her friends, going back to her classes, going back...
Maureen Johnson (The Vanishing Stair (Truly Devious, #2))
The formula presents a symbol of the self, for the self is not just a static quantity or constant form, but is also a dynamic process. In the same way, the ancients saw the imago Dei in man not as a mere imprint, as a sort of lifeless, stereotyped impression, but as an active force. The four transformations represent a process of restoration or rejuvenation taking place, as it were, inside the self, and comparable to the carbon-nitrogen cycle in the sun, when a carbon nucleus captures four protons (two of which immediately become neutrons) and releases them at the end of the cycle in the form of an alpha particle. The carbon nucleus itself comes out of the reaction unchanged, “like the Phoenix from the ashes.”108 The secret of existence, i.e., the existence of the atom and its components, may well consist in a continually repeated process of rejuvenation, and one comes to similar conclusions in trying to account for the numinosity of the archetypes.
C.G. Jung (Aion: Researches into the Phenomenology of the Self (Collected Works, Vol 9ii))
But all the facts were not yet in when Watt was being memorialized in marble in 1825. Because it is the cumulative impact of the carbon emissions that began in those early mills and mines that has already engraved itself in the geologic record—in the levels of the oceans, in their chemical composition, in the slow erasure of islands like Nauru; in the retreat of glaciers, the collapse of ice shelves, the thawing of permafrost; in the disturbed soil cycles and in the charred forests.
Naomi Klein (This Changes Everything: Capitalism vs. The Climate)
A Lady wrote on a Forum "after my body gets old or not and collapses my thoughts which r electrical impulses will cease my body blood etc will melt back into the soil....my last breath which sustains life will go back into the atmosphere so we will be around until our galaxy implodes..." I concur. Who says we die...? I found the epiphany a long time ago that nature is our supreme being and we are going to be here Forever. You die and the grass feeds off your flesh, the cow eats the grass, your children eat the cow and then your children dies and the cycle goes on again. Just as how the carbon dioxide you breathe out is what plants take in and we survive on the oxygen they give out. We are not separate and distinct from nature. We are one. God is a metaphor for the Universe. We are the universe and the universe is in us. It is evident in how the dead meat of an animal or the offspring of a plant gives us life in the form of food then we die and our body deteriorates to fertilize the soil so the plants can survive. The universe is everything. The air that we inhale, the various plants that cures ailments and alleviates various symptoms of diseases. It Should not be cryptic or alien to us to understand how a plant cell completely independent of us can affect our health in such a positive way. That is because the universe is in every one of us.
Crystal Evans (Jamaican Acute Ghetto Itis)
The first policy priority is to integrate adaptation with development. The second is to protect, encourage, and increase terrestrial carbon sinks while honoring a broad range of human and environmental values. The third is to adopt full-cost energy accounting that takes into account the entire life cycle of producing and consuming a unit of energy. The fourth is to raise the price of emitting GHGs to a level that roughly reflects their costs. The fifth priority is to force technology adoption and diffusion. The sixth priority is to substantially increase research, especially in renewable energy and carbon sequestration, particularly air capture of carbon. The seventh priority is to plan for the Anthropocene.
Dale Jamieson (Reason in a Dark Time: Why the Struggle Against Climate Change Failed -- and What It Means for Our Future)
Only a few components of our atmosphere are greenhouse gases, which absorb infrared photons. The three most important are (in order) water vapor, carbon dioxide, and methane. Nitrogen, oxygen, and argon, which make up approximately 99.9% of the dry atmosphere, are not greenhouse gases. • The carbon cycle describes how carbon cycles through its primary reservoirs: the atmosphere (containing 100 GtC), land biosphere (2,000 GtC), ocean (1,000 GtC in
Andrew E. Dessler (Introduction to Modern Climate Change)
The present day is marked by pervasive environmental changes that are clear in almost every geological deposit, whether glacier ice, stalagtites, or sediments from lake-beds or the ocean floor. From spherical carbonaceous particles to microplastics to changes in the carbon and nitrogen cycles indicated by the changing levels of certain carbon and nitrogen isotopes, a human fingerprint is obvious.

Maggie Stiefvater (The Dream Thieves (The Raven Cycle, #2))
far “altogether in vain.” It would take another three-quarters of a century for the question to be resolved. It is now generally believed that ice ages are initiated by small changes in the earth’s orbit, caused by, among other things, the gravitational tug of Jupiter and Saturn. These changes alter the distribution of sunlight across different latitudes at different times of year. When the amount of light hitting the far northern latitudes in summer approaches a minimum, snow begins to build up there. This initiates a feedback cycle that causes atmospheric carbon dioxide levels to

The carbon cycle has grabbed the headlines, but we’ve also seized hold of many other major geochemical cycles. Through production of fertilizers, we’ve radically altered Earth’s nitrogen cycle. The sulfur cycle has become dominated by industrial emissions. We’ve dammed rivers so thoroughly that there is now more than five times as much fresh water captured in reservoirs as there is remaining in all the wild rivers and streams of Earth! That is not a minor change. It’s fair to say that we’ve domesticated a major part of the water cycle of this planet. Earth’s vibrant hydrosphere, arguably our planet’s most distinctive feature, has to some degree become an artifact of human civilization. Every year now, humans constructing roads, buildings, and farms displace ten times more dirt than the combined erosive forces of wind, rain, earthquakes, and tides. Simply measured by the amount of stuff we move around, we have become the undisputed world heavyweight champions
David Grinspoon (Earth in Human Hands: Shaping Our Planet's Future)
We might be excused our ignorance in this case, because ocean-atmosphere systems are, after all, almost inconceivably complex. Less easy to excuse is our astounding lack of knowledge of much more visible features of our planet’s natural resources and ecology—features that have a direct impact on our well-being. For instance, we know surprisingly little about the state of the planet’s soils. While we have good information for some areas, like the Great Plains of the United States, soil data are sketchy for vast tracts of Africa, Asia, and Latin America, where billions of people depend directly on agriculture for survival. So we can’t accurately judge how badly we’ve degraded these soils through overuse and poor husbandry, though we do have patchy evidence that the damage is severe and getting worse in many places.18 Similarly, despite extensive satellite photography, our estimates of the rate and extent of tropical deforestation are rudimentary. We know even less about the natural ecology and species diversity inside these forests, where biologists presume most animal and plant species live. As a result, credible figures on the number of Earth’s species range from 5 to 30 million.19 And when it comes to broader questions—questions of how all these components of the planet’s ecology fit together; how they interact to produce Earth’s grand cycles of energy, carbon, oxygen, nitrogen, and sulfur; and how we’re perturbing these components and cycles—we find a deep and pervasive lack of knowledge, with unknown unknowns everywhere. Our ignorance, for all practical purposes, knows no bounds.
Thomas Homer-Dixon (The Ingenuity Gap: How Can We Solve the Problems of the Future?)
Climate crisis presents nearly unfathomable urgency because of what scientists call “tipping points” – climate tripwires, so to speak. These thresholds, caused by human carbon pollution, trigger dangerous feedbacks capable of unraveling the planet’s climate system. Once triggered, these viscous cycles continue despite any subsequent carbon reductions achieved by humanity. Such tipping points loom near. Some may be underway.
Mary Christina Wood (Nature's Trust: Environmental Law for a New Ecological Age)
Meteorologists agree that our planet is heating up! Now I know that many people disagree with this or just think that it is part of a natural cycle. It doesn’t really matter what we think, because the Earth’s climate will do what it is doing with or without our influence. As part of my profession, I took classes related to the weather and I would just like to share some of my thoughts on this important topic. First, if I know something is heading in the wrong direction, I’ll try to do something about it and if I’m partially to blame, I’ll try a little harder! For years we have been putting carbon up into the atmosphere and now the chickens are coming home to roost! It doesn’t matter what we think about this, however here in Florida the hurricanes have been becoming more violent… as we saw last summer! Statistically the high tides have been just a little higher with each passing year. In fact the average tides have been going up by an inch for every 10 years. That’s an inch per decade! In the Miami area the water has been coming up through the sewer pipes with fish swimming in the streets and here in the Tampa Bay area the streets are flooding, like in the Venetian Isles neighborhood of St. Petersburg, where flooding has been happening about 70 time per year. Can you imagine being flooded out 70 times per year?

Peter D. Ward (The Medea Hypothesis: Is Life on Earth Ultimately Self-Destructive? (Science Essentials Book 23))
By 1942 the Cornell physicist had established himself as a theoretician of the first rank. His most outstanding contribution, for which he would receive the 1967 Nobel Prize in Physics, was to elucidate the production of energy in stars, identifying a cycle of thermonuclear reactions involving hydrogen, nitrogen and oxygen that is catalyzed by carbon and culminates in the creation of helium.
Richard Rhodes (The Making of the Atomic Bomb: 25th Anniversary Edition)
Before the industrial era, when the natural carbon cycle was in balance, the atmosphere contained about 280 parts per million of carbon dioxide.
John Doerr (Speed & Scale: An Action Plan for Solving Our Climate Crisis Now)
This is the famous cycle of life. Carbon dioxide breathed out by animals is absorbed by plants, which make food and oxygen and so on. The cycle needs a constant supply of Gibbs free energy to turn. And crucially, at each step of the cycle, a small amount of free energy is lost as heat. This means at each step the entropy of the universe goes up.
Paul Sen (Einstein's Fridge: How the Difference Between Hot and Cold Explains the Universe)
One of the volumes, “Atmospheric Carbon Dioxide and the Global Carbon Cycle,” noted that CO2 levels had varied in the last million years with a high point, during warm, interglacial phases, of 350 ppm.21 An enormous amount had been learned; the “Projecting the Climatic Effects of Increasing Carbon Dioxide” alone was over 400 pages long, and is full of hard evidence of how much the federal government knew about the impacts of burning fossil fuels.

A common measure of how the climate system responds to human influences, and an important piece of information we hope to learn from models, is the equilibrium climate sensitivity, or ECS. That’s how much the average surface temperature anomaly (recall that the anomaly is the deviation from the expected average) would increase if the CO2 concentration were hypothetically doubled from its preindustrial value of 280 ppm. If emissions continue at their current pace and the carbon cycle doesn’t change much, that doubling would happen in the real world toward the end of this century. The higher the ECS (i.e., the larger the predicted temperature increase), the more sensitive the climate is to human influences (or at least to increased CO2
Steven E. Koonin (Unsettled: What Climate Science Tells Us, What It Doesn’t, and Why It Matters)
The CO2 emitted by burning fossil fuels disrupts the balance of this great annual cycle, since that carbon has been pulled out of the deep underground, where it was isolated from these natural processes. The amount of carbon that fossil fuel use adds to the cycle is currently about 4.5 percent of what flows each year. About half of that increase is taken up annually by the surface (the rising CO2 has increased vegetation over much of the planet), and the remainder stays in the atmosphere, increasing its CO2 concentration.
Steven E. Koonin (Unsettled: What Climate Science Tells Us, What It Doesn’t, and Why It Matters)
Carbon dioxide is the single human-caused greenhouse gas with the largest influence on the climate. But it is of greatest concern also because it persists in the atmosphere/surface cycle for a very long time. About 60 percent of any CO2 emitted today will remain in the atmosphere twenty years from now, between 30 and 55 percent will still be there after a century, and between 15 and 30 percent will remain after one thousand years.
Steven E. Koonin (Unsettled: What Climate Science Tells Us, What It Doesn’t, and Why It Matters)
Carbon dioxide is the single human-caused greenhouse gas with the largest influence on the climate. But it is of greatest concern also because it persists in the atmosphere/surface cycle for a very long time. About 60 percent of any CO2 emitted today will remain in the atmosphere twenty years from now, between 30 and 55 percent will still be there after a century, and between 15 and 30 percent will remain after one thousand years.7 The simple fact that carbon dioxide lasts a long time in the atmosphere is a fundamental impediment to reducing human influences on the climate. Any emission adds to the concentration, which keeps increasing as long as emissions continue. In other words, CO2 is not like smog, which disappears a few days after you stop emissions; it takes centuries for the excess carbon dioxide to vanish from the atmosphere. So modest reductions in CO2 emissions would only slow the increase in concentration but not prevent it. Just to stabilize the CO2 concentration, and hence its warming influence, global emissions would have to vanish.
Steven E. Koonin (Unsettled: What Climate Science Tells Us, What It Doesn’t, and Why It Matters)
1. Data show the CO2 level rose to 410 ppm by 2020, an increase of 130 ppm. 2. The IPCC assumes its core theory is true, which forces the conclusion that human CO2 caused all the increase above 280 ppm. 3. IPCC agrees that human CO2 emissions are less than 5 percent of natural CO2 emissions. 4. How can less that 5 percent of all CO2 emissions cause 32 percent of the CO2 in the atmosphere? Answer: It can’t. 8.2 Multiple lines of evidence prove IPCC’s core theory is wrong. 1. Ice core data prove natural CO2 caused the CO2 increase. 2. Direct CO2 data prove CO2 was much higher than 280 ppm before 1750. 3. Leaf stomata data prove CO2 was much higher than 280 ppm before 1750. 4. Statistics prove human CO2 is not the primary cause of the increase in CO2. 5. IPCC’s human carbon cycle is not consistent with its own natural carbon cycle. This is a basic physics error. 6. Inspection shows IPCC’s human carbon cycle is based on IPCC’s invalid assumption that its core theory is true. 8.3 A simple physics carbon cycle model replicates IPCC’s data for its natural carbon cycle. 1. This model easily calculates the true human carbon cycle that is compatible with IPCC’s natural carbon cycle. 2. The true human carbon cycle shows human CO2 has

There is more heat stored in the first 10 feet of the ocean than in the entire atmosphere. It drives the hydrologic cycle, harbours 80% of all living organisms, absorbs 30% of the carbon dioxide we produce, generates over 50% of the oxygen in the atmosphere, and accounts for over 95% of the habitable space on the planet.

Every single mass extinction in Earth history is similarly marked by massive disruptions of the global carbon cycle, the signals of which have been teased out of the rocks by geochemists.
Greta Thunberg (The Climate Book: The Facts and the Solutions)
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.
E. Kirsten Peters (The Whole Story of Climate: What Science Reveals About the Nature of Endless Change)
Studies of Earth’s chemical and geophysical cycles indicate that temperatures and CO2 levels would remain high for centuries even if emissions were cut to zero today; thus, it seems that only atmospheric carbon capture technologies can provide a large enough drain to lower CO2 levels quickly and deeply.
K. Eric Drexler (Radical Abundance: How a Revolution in Nanotechnology Will Change Civilization)
hyperventilation reduces the concentration of carbon dioxide in the blood. This leads to a narrowing of blood vessels and reduced delivery of oxygen to the brain. An oxygen-deprived brain is more excitable and agitated, and as it floods with self-generated thoughts, anxiety kicks in. One contributes to the other, creating a vicious and self-perpetuating cycle.
Patrick McKeown (The Oxygen Advantage: The Simple, Scientifically Proven Breathing Techniques for a Healthier, Slimmer, Faster, and Fitter You)
A few geologists continue to speak as if they expect Earth to proceed into the next glacial cycle, just as it would have if humans were not around. That glacial period would begin with an ice sheet developing and growing in northern Canada. But why would we allow such an ice sheet to grow, and flow, and eventually crush major cities, when we could prevent it with the greenhouse gases from a single chlorofluorocarbon factory? Humans are now “in charge” of future climate. It is a trivial task to avoid the negative net climate forcing that would push the planet into an ice age (moving conditions toward the left in figure 30). But it is not an easy task to find a way to stop the growth of atmospheric greenhouse gases, most notably carbon dioxide (which moves conditions toward the right in figure 30), as we have been discussing.
James Hansen (Storms of My Grandchildren: The Truth About the Coming Climate Catastrophe and Our Last Chance to Save Humanity)
In Brazil, the rainforests of the Amazon are being destroyed at an alarming rate by bulldozing and burning. There are many excellent reasons to prevent this continuing – loss of habitat for organisms, production of carbon dioxide from burning trees, destruction of the culture of native Indian tribes, and so on. What is not a good reason, though, is the phrase that is almost inevitably trotted out, to the effect that the rainforests are the ‘lungs of the planet’. The image here is that the ‘civilized’ regions – that is, the industrialized ones – are net producers of carbon dioxide. The pristine rainforest, in contrast, produces a gentle but enormous oxygen breeze, while absorbing the excess carbon dioxide produced by all those nasty people with cars. It must do, surely? A forest is full of plants, and plants produce oxygen. No, they don’t. The net oxygen production of a rainforest is, on average, zero. Trees produce carbon dioxide at night, when they are not photosynthesizing. They lock up oxygen and carbon into sugars, yes – but when they die, they rot, and release carbon dioxide. Forests can indirectly remove carbon dioxide by removing carbon and locking it up as coal or peat, and by releasing oxygen into the atmosphere. Ironically, that’s where a lot of the human production of carbon dioxide comes from – we dig it up and burn it again, using up the same amount of oxygen. If the theory that oil is the remains of plants from the carboniferous period is true, then our cars are burning up carbon that was once laid down by plants. Even if an alternative theory, growing in popularity, is true, and oil was produced by bacteria, then the problem remains the same. Either way, if you burn a rainforest you add a one-off surplus of carbon dioxide to the atmosphere, but you do not also reduce the Earth’s capacity to generate new oxygen. If you want to reduce atmospheric carbon dioxide permanently, and not just cut short-term emissions, the best bet is to build up a big library at home, locking carbon into paper, or put plenty of asphalt on roads. These don’t sound like ‘green’ activities, but they are. You can cycle on the roads if it makes you feel better.

What you believe about climate change doesn’t reflect what you know,” said Dan Kahan, a professor at Yale Law School who studies risk perception. “It expresses who you are." To illustrate this point, Kahan cited the results of yet another survey by the Pew Research Center. This survey was designed to test basic scientific knowledge and it posed questions like “What is the main function of red blood cells?” When respondents were asked what gas “most scientists believe causes temperatures in the atmosphere to rise,” 58 percent chose the correct answer: “carbon dioxide.” There was little difference in the proportion of Democrats and Republicans who gave the right response; among the former it was 56 percent, among the latter 58 percent. (Among Independents, 63 percent chose correctly.) But polls that ask Americans about their own beliefs about global warming show a significant partisan divide; in another Pew survey, 66 percent of Democrats said they believed that human activity was the “main cause” of global warming, while only 24 percent of Republicans did. This suggests there are many Democrats who don’t know what’s causing climate change but still believe humans are responsible for it and many Republicans who do know, yet still deny that humans play a role. And what this shows, according to Kahan, is that people’s views on climate change are shaped less by their knowledge of the science than by their sense of group identity. To break the political logjam, he argues, Americans need to find ways of talking about climate change that don’t require members of one group or the other to renounce their cultural identity. “If you show people there is some way of responding to the problem that’s consistent with who they are, then they’re more likely to see the problem,” Kahan told me. Kari Marie Norgaard is a sociologist at the University of Oregon who has studied how people talk about climate change. She, too, believes there’s a strong cultural component to Americans’ attitudes, but she sees the problem as reflecting the strategies people use to avoid painful subjects. Norgaard argues that it’s difficult even for people who are privately worried about climate change to discuss the issue in public because on the one hand they feel guilty about the situation and on the other they feel helpless to change it. “We have a need to think of ourselves as good people,” she told me. Meanwhile, the very lack of discussion about the issue feeds itself: people feel that if it really were a serious problem, others would be dealing with it: “It’s difficult for people to feel that climate change is really happening in part because we’re embedded in a world where no one else around us is talking about it.” “It becomes a vicious cycle between the political gridlock and the cultural and individual gridlock,” Norgaard went on. What could possibly break this cycle? Norgaard argues that if the nation’s political leaders would candidly discuss the issue “it could be very powerful. It could free up a lot of the hopelessness people feel and allow them to mobilize.” “I think there are probably multiple levels at which we could break this cycle,” she went on. And though, after more than thirty years of ignored warnings, the challenge has grown all the more daunting, she said, “I don’t believe we get to give up.

Here’s the information: To practice Wim Hof’s breathing method, start by finding a quiet place and lying flat on your back with a pillow under your head. Relax the shoulders, chest, and legs. Take a very deep breath into the pit of your stomach and let it back out just as quickly. Keep breathing this way for 30 cycles. If possible, breathe through the nose; if the nose feels obstructed, try pursed lips. Each breath should look like a wave, with the inhale inflating the stomach, then the chest. You should exhale all the air out in the same order. At the end of 30 breaths, exhale to the natural conclusion, leaving about a quarter of the air left in the lungs, then hold that breath for as long as possible. Once you’ve reached your breathhold limit, take one huge inhale and hold it another 15 seconds. Very gently, move that fresh breath of air around the chest and to the shoulders, then exhale and start the heavy breathing again. Repeat the whole pattern three or four rounds and add in some cold exposure (cold shower, ice bath, naked snow angels) a few times a week. This flip-flopping—breathing all-out, then not at all, getting really cold and then hot again—is the key to Tummo’s magic. It forces the body into high stress one minute, a state of extreme relaxation the next. Carbon dioxide levels in the blood crash, then they build back up. Tissues become oxygen deficient and then flooded again. The body becomes more adaptable and flexible and learns that all these physiological responses can come under our control. Conscious heavy breathing, McGee told me, allows us to bend so that we don’t get broken.

In the beginning, there was a rapid expansion of a Singularity. Around 380,000 years later, there was light. There was also hydrogen and helium and four stable, fundamental forces of physics. Atoms and those forces worked together to birth the first stars from massive clouds of gas, and those stars lived for hundreds of millions of years before they died in explosions that spread their matter across the sky in clouds of gas and dust—now with heavier elements than what existed before. The forces of physics worked together once again to craft new stars now tightly packed into the first galaxies. As the cycle repeated, heavier elements formed planets orbiting those stars, emerging from disks of gas and dust like dust bunnies under your bed. In our universe, planets can exist only because a few generations of stars died and were reborn. The rebirth of stellar matter into planets is how our Earth came to be. This planet, our home, is covered with a film of life unlike any we’ve yet seen anywhere else in the universe. As far as we know today, it is unique. A blue marble floating in the dark. Earth’s life is fed by a process in which carbon from the air and minerals in the soil are attached together by the energy of photons via photosynthesis in plants. In this process, everything on this planet lives by the constant sacrifice of the nearest star. Every blade of grass, every tree, every bush, every microscopic algae on this planet is a resurrected form of the Sun’s energy. I capture that energy by consuming other things that have died. Every time I eat a meal, the dead matter that made those plants and animals literally gives life to my body through digestion and my metabolism. One day, I will die, and in time my atoms will go back to giving life to something else. Much farther along the arrow of time, our own Sun will explode and spread its essence across the sky. Our Sun’s dust will meet with other stars’ remnants and form new stars and planets of their own. The universe itself exists in an eternal pattern of life, death, and resurrection.

What is food for one creature might be garbage to another. But the carbon keeps cycling along, which is essential for the sustainability of our planet.

This book is a compilation of interesting ideas that have strongly influenced my thoughts and I want to share them in a compressed form. That ideas can change your worldview and bring inspiration and the excitement of discovering something new. The emphasis is not on the technology because it is constantly changing. It is much more difficult to change the accompanying circumstances that affect the way technological solutions are realized. The chef did not invent salt, pepper and other spices. He just chooses good ingredients and uses them skilfully, so others can enjoy his art. If I’ve been successful, the book creates a new perspective for which the selection of ingredients is important, as well as the way they are smoothly and efficiently arranged together. In the first part of the book, we follow the natural flow needed to create the stimulating environment necessary for the survival of a modern company. It begins with challenges that corporations are facing, changes they are, more or less successfully, trying to make, and the culture they are trying to establish. After that, we discuss how to be creative, as well as what to look for in the innovation process. The book continues with a chapter that talks about importance of inclusion and purpose. This idea of inclusion – across ages, genders, geographies, cultures, sexual orientation, and all the other areas in which new ways of thinking can manifest – is essential for solving new problems as well as integral in finding new solutions to old problems. Purpose motivates people for reaching their full potential. This is The second and third parts of the book describes the areas that are important to support what is expressed in the first part. A flexible organization is based on IT alignment with business strategy. As a result of acceleration in the rate of innovation and technological changes, markets evolve rapidly, products’ life cycles get shorter and innovation becomes the main source of competitive advantage. Business Process Management (BPM) goes from task-based automation, to process-based automation, so automating a number of tasks in a process, and then to functional automation across multiple processes andeven moves towards automation at the business ecosystem level. Analytics brought us information and insight; AI turns that insight into superhuman knowledge and real-time action, unleashing new business models, new ways to build, dream, and experience the world, and new geniuses to advance humanity faster than ever before. Companies and industries are transforming our everyday experiences and the services we depend upon, from self-driving cars, to healthcare, to personal assistants. It is a central tenet for the disruptive changes of the 4th Industrial Revolution; a revolution that will likely challenge our ideas about what it means to be a human and just might be more transformative than any other industrial revolution we have seen yet. Another important disruptor is the blockchain - a distributed decentralized digital ledger of transactions with the promise of liberating information and making the economy more democratic. You no longer need to trust anyone but an algorithm. It brings reliability, transparency, and security to all manner of data exchanges: financial transactions, contractual and legal agreements, changes of ownership, and certifications. A quantum computer can simulate efficiently any physical process that occurs in Nature. Potential (long-term) applications include pharmaceuticals, solar power collection, efficient power transmission, catalysts for nitrogen fixation, carbon capture, etc. Perhaps we can build quantum algorithms for improving computational tasks within artificial intelligence, including sub-fields like machine learning. Perhaps a quantum deep learning network can be trained more efficiently, e.g. using a smaller training set. This is still in conceptual research domain.

Evidence for climate change has been available for some time, so why has this 'urgent global response' (in Stern's words) not occurred? The IPCC (2015) have argued that we could limit the effects of climate change by changing our individual and collective behaviour. We could fly less, eat less meat, use public transport, cycle or walk, recycle, choose more low carbon products, have shorter showers, waste less food or reduce home energy use. There has been some significant change but nothing like the 'global response' required to ameliorate the further deleterious effects of climate change. We are reminded here of a somewhat depressing statistic reported by a leading multinational, Unilever, in their 'sustainable Living Plan.' In 2013, they outlined how they were going to halve the greenhouse gas impact of their products across the life cycle by 2020. To achieve this goal, they reduced greenhouse gas emissions from their manufacturing chain. They opted for more environmentally friendly sourcing of raw materials, doubled their use of renewable energy and produced concentrated liquids and powders. They reduced greenhouse gas emissions from transport and greenhouse gas emissions from refrigeration. They also restricted employee travel. The result of all these initiatives was that their 'greenhouse gas footprint impact per consumer... increased by around 5% since 2010.' They concluded, 'We have made good progress in those areas under our control but ... the big challenges are those areas not under direct control like... consumer behaviour ' (2013:16; emphasis added). It seems that consumers are not 'getting the message.' They are not opting for the low carbon alternatives in the way envisaged; they are not changing the length of their showers (to reduce energy and water consumption); they are not breaking their high-carbon habits. The question is why?

Carlton Church: Australia in Doubt on Building Nuclear Plant With the continuous trend of nuclear proliferation, the nuclear-free Australia is in critical dilemma on whether to start the industry in the country or not. On one end of the coin, the negative effects of nuclear generation will surely cause skepticisms and complaints. On the other side, nuclear fuel industry is worth exploring. Prime Minister Malcolm Turnbull has been reserved when it comes to nuclear talks but he did admit that “Australia should ‘look closely’ at expanding its role in the global nuclear energy industry, including leasing fuel rods to other countries and then storing the waste afterwards”. South Australian Premier Jay Weatherill set up a royal commission in March to undertake an independent investigation into the state’s participation in the nuclear fuel cycle. Carlton Church International, non-profit organization campaigning against nuclear use, says there is no need for Australia to venture into nuclear turmoil as they already have an extensive, low cost coal and natural gas reserves. Other critics has also seconded this motion as it is known that even Turnbull has pointed out that the country has plentiful access to coal, gas, wind and solar sources. During an interview, he also stated, “I’m not talking about the politics. We’ve got so much other affordable sources of energy, not just fossil fuel like coal and gas but also wind, solar. The ability to store energy is getting better all the time, and that’s very important for intermittent sources of energy, particularly wind and solar. But playing that part in the nuclear fuel cycle I think is something that is worth looking at closely”. A survey was also conducted among random people and a lot of them have been reluctant about the nuclear issue. Some fear that the Fukushima Daichii Incident would happen, knowing the extent of the damage it has caused even to those living in Tokyo, Japan. Another review also stated, “We only have to look at the Fukushima disaster in Japan to be reminded of the health, social and economic impacts of a nuclear accident, and to see that this is not a safe option for Australians.” According to further studies by analysts, 25 nuclear reactors can be built around Australia producing a third of the country’s electricity by 2050. But it also found nuclear power would be much more expensive to produce than coal-fired power if a price was not put on carbon dioxide emissions. Greenpeace dismissed nuclear power as “an expensive distraction from the real solutions to climate change, like solar and wind power”. - See more at: carltonchurchreview.blogspot

What is it really that makes Earth Earth? The surface, where we live, exists at the interface between two giant heat engines: below us the churning mantle, above us the restless, windy troposphere. All rocky worlds large enough to hold an atmosphere will have some combination of these, and the dynamic possibilities of each realm have been substantially illuminated by the variations we’ve found on other worlds. We live on the convoluted, shifting shoreline between cycles of earth and sky that are incessantly driven by the Sun above and the heat below. So much about our world can be understood as the interplay between these inner and outer cycles. Life thrives at the boundary, enabled and sustained by the great cyclic flows of carbon, nitrogen, oxygen, sulfur, and phosphorous. Still, something else is going on here.

The idea arose when Dan Rothman, a geochemist at MIT, was studying the graphs showing changes in the carbon cycle at the time of the Great Dying. He noticed something about the shape of the curves. He saw a pattern of extremely rapid and accelerating atmospheric and oceanic change that did not look like the simple signature of a volcanic injection of gas into the environment. Rather, it looked to him like a “superexponential” pattern, the kind of increase you see in a gas being exhaled from a rapidly multiplying biological population. He and his colleagues did some detailed mathematical analysis of the geological record, and their results confirmed that the pattern of change was more consistent with biological growth.2 They connected the Great Dying with the evolution and rapid growth of a new type of bacteria that produces methane and multiplies rapidly when it is supplied with the metal nickel, a trace element that was delivered in abundance

Fortunately for us, the sedimentary sink is transitory. Sediments are transported on the giant crustal plates that float like rafts on the hot heavier material of the underlying mantle. When plates converge, they can be either uplifted or they may be withdrawn into the underlying mantle. Uplift results in the formation of mountain ranges. Carbon (and other life-essential elements) may be cycled directly back to the atmosphere/biosphere system, in this case by weathering of the uplifted rock material. If the sedimentary material is carried down into the mantle, it will be raised to high temperature through exposure to the hot mantle material. The carbon and other volatile materials included in the sediments may be released and transferred, often explosively, back to either the atmosphere or ocean as a component of hot springs and volcanoes. The average carbon atom has gone through this tectonically driven cycling sequence at least 10 times over the course of Earth history. How

We can consider the water cycle to start as a gas or vapor in clouds. It starts the cycle as pure H2O (a.k.a. dihydrogen monoxide, or oxidane), but not for long. As it condenses to form water droplets, it absorbs carbon dioxide and other gases from the air. The atmosphere is also full of dust particles and tiny mineral crystals, such as sand and sodium chloride. All of these substances help water droplets to condense, but they also contaminate the water during formation. The droplets agglomerate and fall to the earth as precipitation (rain or snow).

They drive planetary cycles of carbon, nitrogen, sulphur and phosphorus, by converting these elements into compounds that can be used by animals and plants and then returning them to the world by decomposing organic bodies. They were the first organisms to make their own food, by harnessing the sun’s energy in a process called photosynthesis. They released oxygen as a waste product, pumping out so much of the gas that they permanently changed the atmosphere of our planet. It is thanks to them that we live in an oxygenated world. Even now, the photosynthetic bacteria in the oceans produce the oxygen in half the breaths you take, and they lock away an equal amount of carbon dioxide.

Like most stars, the really massive ones begin by burning hydrogen and creating helium. Stars are powered by nuclear energy—not fission, but fusion: four hydrogen nuclei (protons) are fused together into a helium nucleus at extremely high temperatures, and this produces heat. When these stars run out of hydrogen, their cores shrink (because of the gravitational pull), which raises the temperature high enough that they can start fusing helium to carbon. For stars with masses more than about ten times the mass of the Sun, after carbon burning they go through oxygen burning, neon burning, silicon burning, and ultimately form an iron core. After each burning cycle the core shrinks, its temperature increases, and the next cycle starts. Each cycle produces less energy than the previous cycle and each cycle is shorter than the previous one. As an example (depending on the exact mass of the star), the hydrogen-burning cycle may last 10 million years at a temperature of about 35 million kelvin, but the last cycle, the silicon cycle, may only last a few days at a temperature of about 3 billion kelvin! During each cycle the stars burn most of the products of the previous cycle. Talk about recycling! The end of the line comes when silicon fusion produces iron, which has the most stable nucleus of all the elements in the periodic table. Fusion of iron to still heavier nuclei doesn’t produce energy; it requires energy, so the energy-producing furnace stops there. The iron core quickly grows as the star produces more and more iron. When this iron core reaches a mass of about 1.4 solar masses, it has reached a magic limit of sorts, known as the Chandrasekhar limit (named after the great Chandra himself). At this point the pressure in the core can no longer hold out against the powerful pressure due to gravity, and the core collapses onto itself, causing an outward supernova explosion.

Anxiety and excitement are cousins; they can be mistaken for each other at points. They have many features in common—the bubbling, carbonated feel of the emotion, the speed, the wide eyes and racing heart. But where excitement tends to take you up, into the higher, brighter levels of feeling, anxiety pulls you down, making you feel like you have to grip the earth to keep from sliding off as it turns. This was the sympathetic nervous system at work, her therapist had told her. To work with anxiety, you had to let it complete its cycle.
