Carbon Dioxide Quotes

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

Every cow in the world, you know, when they do what they do, you've got more carbon dioxide. ~ John Boehner

A couple degrees warmer would be good for humanity and planet, especially with more plant-fertilizing carbon dioxide in the air. [ ... ] But a couple degrees colder would bring serious adverse consequences for habitats, wildlife, agriculture and humanity. ~ Paul Driessen

It's an appreciation for life generally, every bit of life, the smallest creature that lives in the intestines of termites that make termite life possible - to the leaves that turn out oxygen and grab carbon dioxide and with water make simple sugars that feed much of the world. I mean, these are everyday miracles. ~ Sylvia Earle

As a scientist, my attention became totally focused on global warming some 15 years ago by the elegant and powerful measurements of carbon dioxide trapped in ice cores taken as much as 2 miles deep from the great East Antarctica ice sheet. ~ John Olver

The world beyond 450 ppm atmospheric concentrations of carbon dioxide, the world that crosses carbon cycle tipping points that quickly take us to 1000 ppm, is a world not merely of endless regional resource wars around the globe. It is a world with dozens of Darfurs. It is a world of a hundred Katrinas, of countless environmental refugees ~ Joseph J. Romm

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

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

On a per capita basis, Britain is responsible for more of the carbon dioxide now in the atmosphere than any other nation on Earth because it has been burning it from the dawn of the Industrial Revolution. ~ James Hansen

In an agreement with China, President Obama has already pledged to reduce America's net greenhouse-gas emissions by more than 25% by 2025. In return, China has agreed to 'peak' its carbon-dioxide emissions in 2030. ~ John Barrasso

These things are happening in large measure because of us. We in this country burn 25 percent of the world's fossil fuel, create 25 percent of the world's carbon dioxide. It is us - it is the affluent lifestyles that we lead that overwhelmingly contribute to this problem. And to call it a problem is to understate what it really is. Which is a crime. Crime against the poorest and most marginalized people on this planet. We've never figured out, though God knows we've tried, a more effective way to destroy their lives. ~ Bill McKibben

I believe everyone who breathes air on this earth, regardless of their job or their bank account, must give back more than just carbon dioxide. ~ Kelly Cutrone

There is no doubt there is more carbon dioxide in the atmosphere, caused by the burning of fossil fuels. It should have an effect on the climate, but the numbers indicate that effect is relatively minor. ~ John Christy

I don't like being called a denier because deniers don't believe in facts. There are no facts linking the concentration of atmospheric carbon dioxide with imminent catastrophic global warming there are only predictions based on complex computer models. ~ David Bellamy

We have known since the 1800s that carbon dioxide traps heat in the atmosphere. The right amount keeps the climate conducive to human life. ~ James Hansen

So, if we decrease the use of carbon dioxide, are we not taking away plant food from the atmosphere? ~ John Shimkus

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

The scientific facts indicate that all the temperature changes observed in the last 100 years were largely natural changes and were not caused by carbon dioxide produced in human activities. ~ Robert Jastrow

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

Atmospheric carbon dioxide is increasing, and human activity is the probable cause. ~ Michael Crichton

Is there some magic wand they can wave on it and presto! - physics is overturned and carbon dioxide doesn't trap heat anymore? And when we see all these things happening on the Earth itself, what in the hell do they think is causing it? The scientists have long held that the evidence in their considered word is "unequivocal," which has been endorsed by every national academy of science in every major country in the entire world. ~ Al Gore

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

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

We can look back through ice-core data and see over 800,000 years, relationships between carbon dioxide and the temperature of the world. So those people who deny the importance of climate change are just wasting their time. They're also being diversionary because if we don't act the risks are enormous. ~ Nicholas Stern

Driving a hybrid car could save about one ton of carbon-dioxide emissions per year but adopting a plant-based diet would save nearly one and a half tons over a comparable period."

"If every American reduced chicken consumption by one meal per week, the carbon-dioxide savings would be equivalent to removing 500,000 cars form the road."

In a given year, "the number of animals killed to satisfy American palates is 8.6 billion, or 29 animals per average American meat eater. The total number of animals killed on land and sea was approximately 80 billion, or 270 per American meat and fish eater - making the average number of animals consumed in one American lifetime 21,000. ~ Gene Stone

The science of fermentation is wonderfully simple. Yeast eat sugar. They leave behind two waste products, ethyl alcohol and carbon dioxide. If we were being honest, we would admit that what a liquor store sells is, chemically speaking, little more than the litter boxes of millions of domesticated yeast organisms, wrapped up in pretty bottles with fancy price tags. ~ Amy Stewart

Humanity has nearly suffocated the globe with carbon dioxide, yet nuclear power plants that produce no such emissions are so mired in objections and obstruction that, despite renewed interest on every continent, it is unlikely another will be built in the United States. ~ Michael Specter

Research data on climate change do not show that human use of hydrocarbons is harmful. To the contrary, there is good evidence that increased atmospheric carbon dioxide is environmentally helpful. ~ Frederick Seitz

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

There is no substantive basis for predictions of sizeable global warming due to observed increases in minor greenhouse gases such as carbon dioxide, methane and chlorofluorocarbons. ~ Richard Lindzen

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

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

The Arctic is a place that historically, during all preceding human history, has largely been an icy realm with an impact on ocean currents. That, in turn, influences the temperature of the planet. The Arctic is now vulnerable because of the excess carbon dioxide in the atmosphere, with a rate of melting that is stunning. ~ Sylvia Earle

1.5 billion people lack proper access to electricity. Many buy kerosene, which can cost 30 percent of their income. It sends millions of metric tons of carbon dioxide into the atmosphere every year. And often the lamp will fall over and catch the house on fire. So mothers hate it, but it's their only option. ~ Jacqueline Novogratz

[The doctrine of air] I was led into in consequence of inhabiting a house adjoining to a public brewery, where I at first amused myself with making experiments on the fixed air [carbon dioxide] which I found ready made in the process of fermentation . When I removed from that house I was under the necessity of making the fixed air for myself; and one experiment leading to another, as I have distinctly and faithfully noted in my various publications on the subject, I by degrees contrived a convenient apparatus for the purpose, but of the cheapest kind. ~ Joseph Priestley

Everything on our dinner table-the meat, cheese, salad, bread, and soft drink-requires carbon dioxide to be there. For those of you who believe that carbon dioxide is a pollutant, we have a special diet: water and salt! ~ Joanne Nova

Ocean acidification - the excess carbon dioxide in the atmosphere that is turning the oceans increasingly acid - is a slow but accelerating impact with consequences that will greatly overshadow all the oil spills put together. The warming trend that is CO2-related will overshadow all the oil spills that have ever occurred put together. ~ Sylvia Earle

The general trend in the last 4,000 years is that carbon dioxide and temperature have been moving against each other. ~ Piers Corbyn

Carbon dioxide is natural. It occurs in Earth. It is a part of the regular lifecycle of Earth. In fact, life on planet Earth can't even exist without carbon dioxide. So necessary is it to human life, to animal life, to plant life, to the oceans, to the vegetation that's on the Earth, to the, to the fowl that - that flies in the air, we need to have carbon dioxide as part of the fundamental lifecycle of Earth. ~ Michele Bachmann

Coral reefs, the rain forest of the ocean, are home for one-third of the species of the sea. Coral reefs are under stress for several reasons, including warming of the ocean, but especially because of ocean acidification, a direct effect of added carbon dioxide. Ocean life dependent on carbonate shells and skeletons is threatened by dissolution as the ocean becomes more acid. ~ James Hansen

I must say that when I first learned of the existence of the Australian Greenhouse Office, I assumed it was responsible for supplying tomatoes to the Parliament House kitchen. But, no, as I soon learnt as industry minister, it was in fact a government funded redoubt of veritable soldiers in a war against carbon dioxide. The zealotry and obsessive passion of these warriors in the battle against the apparent evils of carbon dioxide remains a curiosity to me. After fighting these people for three years as industry minister, I really did wish they would just go away and grow tomatoes. ~ Nick Minchin

If you're talking about mugging little old ladies, you don't say, 'What's our target for the rate of mugging little old ladies?' You say, 'Mugging little old ladies is bad, and we're going to try to eliminate it.' You recognize you might not be a hundred percent successful, but your goal is to eliminate the mugging of little old ladies. And I think we need to eventually come around to looking at carbon dioxide emissions the same way. ~ Ken Caldeira

those natural releases are almost perfectly balanced by natural processes that absorb carbon dioxide. For ~ Jeffrey Bennett

Bitumen is junk energy. A joule, or unit of energy, invested in extracting and processing bitumen returns only four to six joules in the form of crude oil. In contrast, conventional oil production in North America returns about 15 joules. Because almost all of the input energy in tar sands production comes from fossil fuels, the process generates significantly more carbon dioxide than conventional oil production. ~ Thomas Homer-Dixon

Human releases of carbon dioxide are almost certainly happening faster than any natural carbon release since the beginning of life on Earth. ~ Mark Lynas

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

If we want to stabilize the carbon dioxide in the atmosphere at some level - it really doesn't matter which level - you end up having to stop emissions virtually completely. ~ Klaus Lackner

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

In the head-spinning cosmos of climate change, everyday hundreds of people claim there are 'thousands of papers' in support of a theory, yet no one can actually name one single paper with empirical evidence that shows carbon dioxide emissions are the main cause of global warming. ~ Joanne Nova

Carbon dioxide isn't the only greenhouse gas out there. Other substances, such as water vapor and nitrous oxide, also trap heat to varying degrees. ~ Jamais Cascio

If it were only a few degrees, that would be serious, but we could adapt to it. But the danger is the warming process might be unstable and run away. We could end up like Venus, covered in clouds and with the surface temperature of 400 degrees. It could be too late if we wait until the bad effects of warming become obvious. We need action now to reduce emission of carbon dioxide. ~ Stephen Hawking

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

[W]hen we look at the graphs of rising ocean temperatures, rising carbon dioxide in the atmosphere and so on, we know that they are climbing far more steeply than can be accounted for by the natural oscillation of the weather ... What people (must) do is to change their behavior and their attitudes ... If we do care about our grandchildren then we have to do something, and we have to demand that our governments do something. ~ David Attenborough

Climate change is a crucial issue in todays global agenda. Hopefully, we will wake up to this reality, sooner rather than later. Pressure has been mounting on European Union Member States to act decisively to fight global warming. A bold target has been set reducing carbon dioxide emissions by 20 by 2020. ~ Joseph Muscat

The fundamental reason why carbon dioxide in the atmosphere is critically important to biology is that there is so little of it. A field of corn growing in full sunlight in the middle of the day uses up all the carbon dioxide within a meter of the ground in about five minutes. If the air were not constantly stirred by convection currents and winds, the corn would stop growing. ~ Freeman Dyson

Those who are absolutely certain that the rise in temperatures is due solely to carbon dioxide have no scientific justification. It's pure guesswork. ~ Henrik Svensmark

If you choose to make regulations about carbon dioxide, that's OK. You as a state can do that; you have a right to do it. But it's not going to do anything about the climate. And it's going to cost, there's no doubt about that. ~ John Christy

They absorb carbon monoxide and carbon dioxide and give out oxygen. What could be more desirable? And they look good in the bargain. Stop chopping down the rain forests and plant more saplings, and we're on our way. ~ Isaac Asimov

Natural gas emits only half the carbon dioxide of coal when burned, but if methane leaks when oil companies extract it from the ground in a sloppy manner - methane is far more potent a greenhouse gas than carbon dioxide - it can wipe out all the advantages of natural gas over coal. ~ Thomas Friedman

Society's emissions of carbon dioxide may or may not turn out to have something significant to do with global warming-the jury is still out. ~ Edward Teller

NASA's Aqua satellite is showing that water vapor, the dominant greenhouse gas, works to offset the effect of carbon dioxide (CO2). This information, contrary to the assumption used in all the warming models, is ignored by global warming alarmists. ~ Walter Cunningham

The announcement yesterday follows Obama's 2011 agreement with automakers to build cars that average 54.5 miles per gallon by 2025. But as important as fuel efficiency in automobiles may be, power plants are the largest concentrated source of carbon dioxide emissions. The EPA's new power-plant rules will reduce overall emissions by at least 80 times more metric tons of carbon than the regulations for cars. Almost all credible reports suggest the world is passing the point where it can reverse, or eliminate, global warming. But that only means it's more urgent than ever to push for historic carbon reductions. Nonetheless, many politicians - including the usual global-warming deniers and those from both parties in fossil-fuel-producing states - rushed to claim the new rules would cause steep economic damage. ~ Anonymous

No chemical compound in the atmosphere has a worse reputation than CO2, thanks to the single-minded demonization of this natural and essential atmospheric gas by advocates of government control and energy production. The incredible list of supposed horrors that increasing carbon dioxide will bring the world is pure belief disguised as science. ~ William Happer

I am hoping that the scientists and politicians who have been blindly demonizing carbon dioxide for 37 years will one day open their eyes and look at the evidence. ~ Freeman Dyson

In the course of my stay there, I also showed how one could analyse the experimental kinetic curves for the reaction of haemoglobin with carbon dioxide or oxygen by simulations in the computer, and so fit the rate constants. ~ Aaron Klug

Coal is responsible for as much atmospheric carbon dioxide as other fossil fuels combined and it still has far greater reserves. We must stop using it. ~ James Hansen

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

My instinct, of course, is to imagine us as one of many planets racing its evolution against its sun--merely one in the galactic Darwinian pursuit. But maybe we're not. Maybe all this talk of the inevitability of aliens is garbage and we're miraculously, beautifully alone in our biological success. What if we're winning? What if we're actually the most evolved intelligence in all this big bang chaos? What if other planets have bacteria and single-celled genotypes but nothing more?

The precedent is all the more pressing. Humans alone could be winning the race against our giant gas time bomb and running with the universal Olympic torch. What an honor. What a responsibility. What a gift we have been given to be born in an atmosphere with oxygen and carbon dioxide and millions of years and phenotypes cheering us on with recycles of energy.

The thing is, I think we can make it. I think we can shove ourselves into spaceships before things get too cold.

I only hope we don't fuck things up before that. Because millions of years is a long time and I don't want to let the universe down. ~ Marina Keegan

The European auto industry made a commitment to reduce carbon dioxide emissions by an average of 140 grams per kilometer. But then there was a significant change in what customers wanted in their vehicles. ~ Martin Winterkorn

The atmosphere is only about .035 percent carbon dioxide, ~ Cynthia Stokes Brown

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

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

I have not been one who believed in the global warming. But I tell you, they are making a convert out of me as these blistering summers. They have broken heat records in a number of cities already this year and broken all-time records and it is getting hotter and the ice caps are melting and there is a build up of carbon dioxide in the air. We really need to address the burning of fossil fuels. ~ Pat Robertson

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

My first inclination is to be a bit skeptical about the claims that human-produced carbon dioxide is the direct contributor to global warming. ~ Buzz Aldrin

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

There are a number of causes of climatic change, and until all causes other than carbon dioxide increase are ruled out, we cannot attribute the change to carbon dioxide alone. ~ Reid Bryson

Lambic is flat, since all carbon dioxide produced during lambic fermentation escapes from the barrel. Packaged young, lambic develops carbonation in a manner similar to a cask or bottle of real ale. Real ale is casked or bottled at the end of fermentation with just enough fermentable sugar left in solution to provide a gentle carbonation. The microorganisms responsible for lambic fermentation can consume virtually any type of sugar; therefore, the brewer never bottles young lambic. The fermentation of the remaining sugar in young lambic would produce enough carbon dioxide to shatter the bottle. ~ Jeff Sparrow

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

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

Just about every scientist outside the White House believes climate change is real, is serious, and is accelerated by the continue release of carbon dioxide. If the prospect of melting ice caps, rising sea levels, changing weather patterns, more frequent hurricanes, more violent tornadoes, endless dust storms, decaying forests, dying coral reefs, and increase in respiratory illness and insect-borne diseases - if all that doesn't constitute a serious threat, I don't know what does. ~ Barack Obama

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

When Glacier Park was established in 1910, it had about 150 glaciers. Today, with human activities spewing carbon dioxide and methane as if we were intent on re-creating Earth's ancient atmosphere, a warming climate has reduced the number of glaciers to 25, and thoses are shrinking three to four times as fast as they were just half a century ago. The last one is expected to vanish by 2020. ~ Douglas Chadwick

There is no proof that carbon dioxide is causing or precedes global warming ... All indications are that the minor warming cycle finished in 2001 and that Arctic ice melting is related to cyclical orbit-tilt-axis changes in earth's angle to the sun. ~ John Williams

President Bush insisted today that he was not caving in to big money contributors, big-time lobbyists, and overall industry pressure when he broke a campaign promise to regulate carbon dioxide emissions from power plants. But the air was thick today with accusations from people who believe that's exactly what happened. ~ Dan Rather

Too many cars, too many factories, too much detergent, too much pesticides, multiplying contrails, inadequate sewage treatment plants, too little water, too much carbon dioxide - all can be traced easily to too many people. ~ Paul R. Ehrlich

It's not the case that carbon dioxide drives temperatures. When you leave Ice Ages, it's the other way around: The temperatures go up first, and then carbon dioxide levels go up. ~ Piers Corbyn

The concentration of atmospheric carbon dioxide has changed greatly since fossilized life began on Earth nearly 600 million years ago. In fact, there is only 1/19 as much CO2 in the air today as there was 520 million years ago. That high CO2 was hardly the recipe for disaster. ~ Greg Benson

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

Writing is my oxygen. Music is my carbon dioxide. ~ Jessica Bell

Claiming that a little piece of green paper is more important than, say, the tree it's made from - even though that tree provides oxygen and absorbs carbon dioxide from the atmosphere. Without the trees, we would all die out, but cash is an invention that is less than two thousand years old. ~ Bella Forrest

Organisms in the ocean provide over 40 percent of the oxygen we breathe, and they're the major sink for capturing all the carbon dioxide we constantly release into the atmosphere. ~ Craig Venter

Burning carbon-based substances like oil, gas, and especially coal, produces billions of tons of extra carbon dioxide each year. Methane gas from cows and pigs and other animals on our large farms ends up in the atmosphere as well, trapping more of the sun's energy as heat. ~ Bill Nye

How long have we got? We have to stabilize emissions of carbon dioxide within a decade, or temperatures will warm by more than one degree ... We don't have much time left. ~ James Hansen

I drove an electric car for seven years because of its advanced technology, not because I have any concerns about energy resources. I have none at all. And when environmentalists say that global warming is dangerous, unprecedented and that we'll have a tipping point for atmospheric carbon dioxide, it's just nonsense. ~ Burt Rutan

The key players are now all in place in Washington and in state governments across America to officially label carbon dioxide as a pollutant and enact laws that tax us citizens for our carbon footprints. ~ John Coleman

What makes tar sands particularly odious is that the energy you get out in the end, per unit carbon dioxide, is poor. It's equivalent to burning coal in your automobile. ~ James Hansen

When you have energy companies like Shell and British Petroleum, both of which are perhaps represented in this room, saying there is a problem with excess carbon dioxide emission, I think we ought to listen. ~ James Baker

The greenhouse effect of carbon-dioxide emissions does produce gentle warming if it is not counteracted by unpredictable natural phenomena, but it cannot be measured directly against the volume of such emissions. ~ Conrad Black

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