Co2 Quotes & Sayings

Every footstep we take, every action has a consequence. We breathe in weather, but we breathe out CO2. We're responsible for weather and for climate. — Gretel Ehrlich

Many people believe the whole catastrophe is the oil we spill, but that gets diluted and eventually disarmed over time. In fact, the oil we don't spill, the oil we collect, refine and use, produces CO2 and other gases that don't get diluted. — Carl Safina

The science is clear that there is an increase in the amount of CO2 in the atmosphere. What is not clear from the science is how much of that increase is caused by human activity; and what also is not clear is what impact those increases have on the climatic cycle. — Jim Sensenbrenner

I thought if the climate was heating that CO2 was the only forcing, and it would be late in the century before we had trouble. Now that we know about the other half of the forcing, it's obvious that the trouble is coming much sooner. — Paul R. Ehrlich

It's important to see things in perspective. Automobile traffic is responsible for only 12 percent of total CO2 emissions. One should be able to point this out without being accused of changing the subject. — Martin Winterkorn

The majority of humankind does not accept this system, despite claims of worldwide support. Even with Russia's ratification, 75% of the world's CO2 is emitted by, 68% of the world's GDP is produced in, and 89% of the world's population live in countries that are not handcuffed by Kyoto's restrictions. Like fascism and communism, Kyotoism is an attack on basic human freedoms behind a smokescreen of propaganda. Like those ideologies of human hatred, it will be exposed and defeated. — Andrey Illarionov

Whereas CO2 is the dominant greenhouse gas overall, it accounts for only 11 percent of agricultural emissions.2 The rest is nitrous oxide (53 percent) and methane (36 percent). Nitrous oxide is 296 times more potent per pound than CO2 as a climate-change gas, and on farms it results mainly from the use of fertilizer but also from cattle pee, especially if there is excessive protein in their diet, and from the burning of biomass and fuel.3 Methane, which is 25 times more potent than CO2, is mainly emitted by cows and sheep when they belch. Some is also emitted from silage. The CO2 comes from machinery but also from the heating of greenhouses to grow crops out of season or in countries that just don't have the right climate. — Mike Berners-Lee

The scientists who do climate research understand that much of the ever increasing concentration of CO2 in the atmosphere since 1850 must be attributed to burning those fossil fuels to produce the energy that drives industrialization. — John Olver

Absolutely love the new campaign from the Optimum Population Trust: do your bit for addressing climate change by having fewer children - or even no children. The lifetime CO2 emissions of a UK citizen amount to 750 tonnes (the equivalent - apparently - of 620 return flights between London and New York), so the extra 10 million by which our population will rise between now and 2074 will, over their lifetimes, emit around 7½ billion tonnes of CO2 ... "births averted" is probably the most single most substantial and cost-effective intervention that governments could be using — Jonathon Porritt

I think the whole human-induced greenhouse gas thing is a red herring ... I see climate change as due to the ocean circulation pattern. I see this as a major cause of climate change ... These are natural processes. We shouldn't blame them on humans and CO2. — William M. Gray

It is important that carbon storage is carefully regulated, that the process is transparent to the public, and that there is a clear accounting of what happened to the CO2. This is particularly true of underground storage, where there is always a small chance that pressurized CO2 could escape. — Klaus Lackner

To reduce modern climate change to one variable, CO2, or a small proportion of one variable - human-induced CO2 - is not science. To try to predict the future based on just one variable (CO2) in extraordinarily complex natural systems is folly. Yet when astronomers have the temerity to show that climate is driven by solar activities rather than CO2 emissions, they are dismissed as dinosaurs undertaking the methods of old-fashioned science. — Ian Plimer

I took another draught and my mouth was awash again in a riptide of bitter, bubbly, CO2 eruptions and the fruity splash of malted barley. What a sensation! I wasn't sure if I liked it at first, but by bottle's end I was a dedicated fan. — Joel Miller

Dickens knew there were vast reserves of methane hydrate trapped frozen in sea-beds all around the world and wondered what would happen if a lot of that frozen methane on the sea floor had melted from a solid into a gas, and bubbled up from the ocean's depths? Would it be enough to account for the "signature" of carbon-12 that geologists were finding in the rocks associated with the Permian Mass Extinction? So he went back to the lab and melted frozen methane in water warm enough. The results were dramatic. The gas not only dissolved into the water, but it also rose up out of the water and into the air. Dickens published a paper in 1999 suggesting that a 5 degree Celsius increase in ocean temperatures would have been adequate to melt enough methane hydrate crystals to create the Permian carbon-12 signature. And such a massive release of methane, itself a greenhouse gas vastly more potent than CO2, would also trigger a catastrophic, swift warming of the planet. — Thom Hartmann

There is still zero empirical evidence that anthropogenic production of CO2 is making any measurable contribution to the world's present warming trend. — Alexander Cockburn

Prime Minister Cameron says he wants to be the greenest government ever, but the definition of green is immature ... I don't deny for a moment that CO2 is a greenhouse gas, but there are so many other factors that affect climate. It is more complicated than the computer models that we are using. What the truth is, nobody knows. — Nigel Lawson

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

I'm really interested in how you create a whole new economy of recycling. It's literally the 'underground economy.' All this stuff that on the surface creates growth and profit, ends up with waste, junk, and CO2. So how do you make it economic to bring new players into the ball game? — Peter Senge

I think all countries need to aim to cut the CO2 emissions per person, taking account of externalities like imports and exports. — Martin Rees

Natural gas obviously brings with it a number of quality-of-life environmental benefits because it is a relatively clean-burning fuel. It has a CO2 footprint, but it has no particulates. It has none of the other emissions elements that are of concern to public health that other forms of power-generation fuels do have: coal, fuel oil, others. — Rex Tillerson

The sea is a spirit level, a pantry, a playground, a mansion rowdy with life, a majestic reminder of our origins, another kind of body (a body of water), and female because of her monthly tides. But her bones are growing brittle, her brine turning ever more acidic from all the CO2 we've slathered into the air and all the fertilizer runoff from our fields. — Diane Ackerman

The physical relationship between CO2 molecules and the atmosphere and the trapping of heat is as well-established as gravity, for God's sakes. It's not some mystery. — Al Gore

We thus find ourselves in the situation that the entire theory of man-made global warming-with its repercussions in science, and its important consequences for politics and the global economy-is based on ice core studies that provided a false picture of the atmospheric CO2 levels. — Zbigniew Jaworowski

CO2 is so beneficial ... it would be crazy to try to reduce it — Freeman Dyson

In a well-monitored storage site, it is always possible to release CO2 in a controlled manner in the unlikely event that it threatens to escape. Such a release is certainly no worse than ignoring the emission in the first place. — Klaus Lackner

CO2 is a minor player in the total system, and human CO2 emissions are insignificant compared to total natural greenhouse gas emissions. Therefore, lowering human CO2 emissions will have no measurable effect on climate, and continued CO2 emissions will have little or no effect on future temperature ... While controlling CO2 emissions from burning fossil fuels may have some beneficial effects on air quality, it will have no measurable effect on climate, but great detrimental effects on the economy and our standard of living. — Jonathan Duhamel

I'm not a global warming believer. I'm not a global warming denier. I'm a global warming agnostic who believes instinctively that it can't be very good to pump lots of CO2 into the atmosphere but is equally convinced that those who presume to know exactly where that leads are talking through their hats. — Charles Krauthammer

Eventually we'll use a CO2 tax offset by a reduction in taxes elsewhere alongside a cap-and-trade plan, but the degree of difficulty associated with a CO2 tax far exceeds that with a cap-and-trade plan. We're seeing it's hard to get a cap-and-trade plan and it's much easier to use as a basis for a global agreement than a CO2 tax. — Al Gore

Back in 2005, when I was Christopher Eccleston, we saw one of the largest increases on record, of CO2 in the atmosphere. Unless we keep the rise in global temperature to under 2 degrees, by the time I'm Daniel Radcliffe or wee Jimmy Crankie, I won't be able to save the planet. I won't be here to help you
well I might, but I'll be that bloke who won Any Dream Will Do. — David Tennant

What historians will definitely wonder about in future centuries is how deeply flawed logic, obscured by shrewd and unrelenting propaganda, actually enabled a coalition of powerful special interests to convince nearly everyone in the world that CO2 from human industry was a dangerous, planet-destroying toxin. It will be remembered as the greatest mass delusion in the history of the world - that CO2, the life of plants, was considered for a time to be a deadly poison. — Richard Lindzen

For me the two biggest issues are climate change and animal welfare/animal agriculture. And oddly enough animal agriculture is such a contributor to climate change. According to the United Nations, 25% of climate change comes from animal agriculture, so every car, bus, boat, truck, airplane combined has less CO2 and methane emissions than animal agriculture. — Moby

Doom yourself to horrific climate change by burning all that carbon and releasing all that CO2. Or power down society, reducing total energy usage around the planet. One leads to ecological collapse. The other is a reversion, in many ways, to poverty. — Ramez Naam

Organisms don't think of CO2 as a poison. Plants and organisms that make shells, coral, think of it as a building block. — Janine Benyus

Even if you accept the theory of man-made climate change, wind turbines are a rotten way to reduce CO2 emissions, or to improve energy security. — Roger Helmer

We allow it to be dumped into this community asset, which is our one and only atmosphere. So that has to change, and there's really only one entity that can do that. So we have proposed a cap-and-trade system to stop that unlimited pollution, to use the forces of the market to efficiently allocate scarce permits to allow CO2 into the atmosphere. That's just one of 500 things we need to do, but it's probably the granddaddy of them all. — Jay Inslee

CO2 is the exhaling breath of our civilization, literally ... Changing that pattern requires a scope, a scale, a speed of change that is beyond what we have done in the past. — Al Gore

If we don't start thinking big about the CO2 problem, we may miss our opportunity to stop a climate runaway that will trash the habitable parts of the earth. — William H. Calvin

Beneath the ocean surface, bad things are happening. Increasing CO2 makes ocean water more acid, and that threatens to dissolve the shells of some ocean animals. Ouch, how'd you like to have your shell dissolve? — Mark Powell

It looks as though yields of over 10 times what we can currently grow per acre are feasible if you control the CO2 concentration, the humidity, the temperature, all the various factors that plants depend on to grow rapidly. — Ralph Merkle

The oceans that surround the world produce 185 billion tons of CO2 per annum. Man per annum only produces six billion tons, so what could possibly be the concern? — John Raese

European carmakers pledged to reduce CO2 emissions by 25 percent from 1995 to 2008. We kept our word and reduced the value even more. This is not the result of short-term gimmickry. We decided years ago to develop the relevant models and engines, otherwise we wouldn't be able to offer them today. — Norbert Reithofer

We need to raise the level of our game in terms of explaining the planetary warming by infrared absorption of CO2 etc. The missing area of understanding seems to be the actual physical mechanism. Lets target an explanation at an audience that has taken 1 year each of undergraduate physics and chemistry, plus calculus. Once we have something that is convincing at this level, we can work on how to communicate this to the interested public (i.e. those that hang out in the climate blogosphere). Willis Eschenbach's help is needed in translating this for the WUWT crowd. — Judith Curry

Make no mistake: Tackling climate change is vital. But to see everything through the lens of short-term CO2 reductions, letting our obsession with carbon blind us to the bigger picture, is to court catastrophe. — Alex Steffen

Local and state governments have outrun the federal government. The EPA has served notice that it will enact a rule requiring CO2 reductions by major emitters in the absence of major legislation. But it's a blunt instrument that is a little more difficult to use than a legislative remedy. — Al Gore

Weather patterns over the next 20 or 30 years are going to be determined by the amount of CO2 that is up there now — John Beddington

Yeah, hey you know carbon sinks are so crucial, scrubbing CO2 out of the air may eventually turn out to be our only option, so maybe we should reverse those two clauses. Make carbon sinks come first and the climate-neutral power plants second in that paragraph." "You think?" "Yes. Definitely. Carbon sinks could be the only way that our kids, and about a thousand years' worth of kids actually, can save themselves from living in Swamp World. From living their whole lives on Venus. — Kim Stanley Robinson

We can no longer completely avoid anthropogenic climate change. At best, limiting the temperature rise to two degrees is just about possible, according to optimistic estimates. That's why we should spend more time talking about adjusting to the inevitable and not about reducing CO2 emissions. We have to take away people's fear of climate change. — Hans Von Storch

If you didn't auction the [CO2] permits, it would represent the largest corporate welfare program that has ever been enacted in the history of the United States. All of the evidence is that what would occur is that corporate profits would increase by approximately the value of the permits. — Peter R. Orszag

The European Union and environmental advocacy groups use global warming hysteria to advance their own special agendas. The European Union recognizes any significant reduction in CO2 emissions by the United States will significantly reduce its economic output, thereby bringing it closer to the inferior output of European nations. — Jay H. Lehr

There is some CO2-water vapor feedback. But it's not operating on a global scale. The modellers cannot accurately separate water vapour from the effects of clouds and rainfall. — Willie Soon

Even if producing CO2 was good for the environment, given that we're going to run out of hydrocarbons, we need to find some sustainable means of operating. — Elon Musk

The fact that companies are getting into building power plants that collect their own CO2 on-site shows there's some leadership in that industry. Some industries have seen the writing on the wall: that carbon will have to be managed. — Klaus Lackner

The industrialization of China alone would increase by 90 percent the concentration of CO2 in our atmosphere and would at least increase the atmospheric CO2 by at least another 100 parts per million. — John Olver

What is the environmental policy of the Republican Party? When I ask that question, I get a blank stare, if I'm president of the United States, we're going to address climate change and CO2 emissions in a business-friendly way. — Lindsey Graham

Sunspots and cosmic rays have a 79 percent correlation with our thermometer record since 1860. Meanwhile the CO2 correlation is a mere 22 percent. — Dennis T. Avery

The Volkswagen Group offers the world's largest low-CO2 fleet. — Martin Winterkorn

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

In the European Union, a fleet average of 95 grams of CO2 per kilometer will be permitted in 2020. This corresponds to fuel consumption of about four liters (per 100 kilometers; about 59 mpg). We have to continue reducing the fuel consumption of our vehicles and offer hybrid and electric vehicles, or else we will be unable to achieve these values. — Norbert Reithofer

About fifty million years ago ... geological evidence indicates CO2 levels were several thousand ppm, much higher than now. And life flourished abundantly. — William Happer

Despite all the progress climate scientists have made in understanding the risks we run by loading the atmosphere with CO2, the world is still as addicted to fossil fuels as ever. — Jeff Goodell

To reduce the interpretation of the causality of all kinds of climate changes and of global warming to one variable, CO2, or to a small proportion of one variable - human-induced CO2 - is impossible to accept. Elementary rationality and my decades-long experience with econometric modelling and statistical testing of scientific hypotheses tell me that it is impossible to make strong conclusions based on mere correlation of two (or more) time series. — Vaclav Klaus

C'mon kids! Wake up and smell the CO2! Take over your administration building, occupy your university president's office, or storm in on the next meeting of your college's board of trustees until they agree to make your school carbon neutral. — Thomas Friedman

The role of CO2 is not nearly as clear as the climate catastrophists would suggest. — Tony Abbott

The idea that somewhere in the desert far away you have a CO2 absorber that's removing the CO2 from the air is an attractive one. It's a costly process that many will say is too expensive, but so are fuel cells in cars. It's a matter of political will to move this forward. — Klaus Lackner

It is the fight for a new economy, a new energy system, a new democracy, a new relationship to the planet and to each other, for land, water, and food sovereignty, for Indigenous rights, for human rights and dignity for all people. When climate justice wins we win the world that we want. We can't sit this one out, not because we have too much to lose but because we have too much to gain. . . . We are bound together in this battle, not just for a reduction in the parts per million of CO2, but to transform our economies and rebuild a world that we want today. — Naomi Klein

We face the gravest threat that civilization has ever confronted. It's global in nature and requires a global solution. Increased CO2 emissions anywhere, whether from China or the United States or from one of the countries that is burning its forests like Brazil or Indonesia. — Al Gore

The atmosphere does not fathom whether CO2 comes from U.S. oil or Chinese coal, nor do hurricanes lose force because the Heritage Foundation doesn't believe global warming is a problem. Living systems operate on laws over which we have no say. — Paul Hawken

It's not as though we can keep burning coal in our power plants. Coal is a finite resource, too. We must find alternatives, and it's a better idea to find alternatives sooner then wait until we run out of coal, and in the meantime, put God knows how many trillions of tons of CO2 that used to be buried underground into the atmosphere. — Elon Musk

The US in some ways has been the best. Who figured out shale gas? Although that wasn't a good thing [for CO2 levels], it was very innovative. It's led to low-cost energy. Who figured out nuclear power? Largely the United States. Once you get past the steam engine, which is mostly British, then the US has been at the center of most of the energy things that have happened. — Bill Gates

When Arnold Schwarzenegger goes to his reward - how's that? That's a crack, but I treat Governor Schwarzenegger well in my book. He's done such great work in California; we'll forgive him one personal habit. Everybody should have one not-totally-CO2-friendly habit they can be forgiven for. So we'll forgive him that one. — Jay Inslee

Climate change is a global issue - from the point of view of the Earth's climate, a molecule of CO2 emitted in Bejing is the same as a molecule emitted in Sydney. — Jeff Goodell

Other calculations of his show that to keep pace with the present rate of temperature change, plants and animals would have to migrate poleward by thirty feet a day, and that a molecule of CO2 generated by burning fossil fuels will, in the course of its lifetime in the atmosphere, trap a hundred thousand times more heat — Elizabeth Kolbert

I am not a global warming sceptic. I accept that rising human-caused CO2 from fossil sources could 'change the climate'. The basic physics is there to support this view. But where is the evidence that the putative change would be large or damaging? — Chris De Freitas

It is in fact necessary to reduce CO2 emissions. There is no reason why we shouldn't spend our vacations on (the North Sea island of) Sylt instead of in the Seychelles, or drive more economical cars - for the sake of preserving increasingly scarce resources if nothing else. But that won't enable us to stop climate change. As long as China, India and the United States continue the way they have been, what we Germans do is more or less irrelevant. — Hans Von Storch

Adding CO2 to the air is like throwing another blanket on the bed. — James Hansen

Only by advocating 'politically unrealistic' CO2 concentrations can runaway global warming be avoided. But what is politically realistic for humans is whollymunrelated to what is physically realistic for the planet. — Mark Lynas

How strange that so few people ever looked up from the spice long enough to wonder at the near-ideal nitrogen-oxygen-CO2 balance being maintained here in the absence of large areas of plant cover. — Frank Herbert

It is impossible to talk about slowing climate change without talking about reducing CO2 emissions. Equally, it is impossible to talk about adapting to climate change without considering how we will feed ourselves. And it is out of the question that we can adapt agriculture without conserving crop diversity. — Cary Fowler

A magical CO2 knob for controlling weather and climate simply does not exist! — Willie Soon

Concentration of greenhouse gases, especially CO2, have increased substantially since the beginning of the industrial revolution. And the National Academy of Sciences indicates that the increase is due in large part to human activity. — George W. Bush

Injecting CO2 into an underground reservoir would certainly change the local environment and thus affect the organisms that live there. Some will thrive, and others will suffer. While we should minimize such impacts, they cannot be avoided completely. The same happens when one plows a field, builds a house or a road, or waters a lawn. — Klaus Lackner

There are many direct biological benefits that result from higher atmospheric CO2 concentrations. Two of the most important are increased plant photosynthesis and water-use efficiency. — Keith E. Idso

CO2 cannot cause global warming. I'll tell you why. It doesn't mix well with the atmosphere, for one. For two, its specific gravity is 1 1/2 times that of the rest of the atmosphere. It heats and cools much quicker. Its radiative processes are much different. So it cannot - it literally cannot cause global warming. — Joe Bastardi

If you really could take the CO2, when you burn hydrocarbons - coal, for example - if you could really capture the carbon and sequester it - they call it CCS - if the extra capital cost, energy cost, and storage costs over time didn't make it super expensive, then that's another path that you could go down. — Bill Gates

Those individuals from the far left, and I'm talking about the Hollywood elitists and the United Nations and those individuals want us to believe it's because we are contributing CO2 to the atmosphere, that's causing global warming. It's all about money. I mean, what would happen to the Weather Channel's ratings if all the sudden people weren't scared anymore? — James Inhofe

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

Past, present and future CO2 emissions will have a cumulative impact on both global warming and ocean acidification. The laws of physics are non-negotiable. — Anonymous

I particularly dislike the high-profile switch-off campaigns where whole cities are plunged into darkness for an hour as a supposedly symbolic gesture about energy use. So is the implication that we all need to live in constant gloom to reduce CO2 emissions? — Mark Lynas

By burning fossil fuels, we are already dumping 30 billion tons of CO2 into the atmosphere every year, which has a profound effect on the climate. So, like it or not, we're already messing with a system we don't understand. — Jeff Goodell

The problem with small pressure vessels is CO2 toxicity. You can have all the oxygen in the world, but once the CO2 gets above 1 percent, you'll start to get drowsy. At 2 percent, it's like being drunk. At 5 percent, it's hard to stay conscious. Eight percent will eventually kill you. Staying alive isn't about oxygen, it's about getting rid of CO2. — Andy Weir

We designed a car that is for daily commutes and that you charge every day. The less you use the gasoline engine, the better mpg. Essentially, the Karma can achieve dramatic savings and low CO2 output when used as intended, as a daily commuter. — Henrik Fisker

Naturally, we will continue to offer very powerful vehicles in the future. Nevertheless, no other manufacturer has reduced the CO2 emissions of its fleet as substantially as the BMW Group. — Norbert Reithofer

It's fine if you're making 1,000 or 2,000 of an electric car, and I think there is value in that in a lot of ways, but it's not going to have a big dent in oil consumption in the country, or CO2 emissions. — Rick Wagoner

My view is that we don't know what's causing climate change on this planet. And the idea of spending trillions and trillions of dollars to try to reduce CO2 emissions is not the right course for us. — Mitt Romney

For nearly a decade now, there has been no global warming. Even though atmospheric CO2 has continued to accumulate - up about 4 percent in the last 10 years - the global mean temperature has remained flat. That should raise obvious questions about CO2 being the cause of climate change. — Walter Cunningham

CO2 is a pollutant? Tell that to the plants. — Rick Santorum

There appears to be a lot of confusion about the biological benefits of elevated CO2 because the popular media typically fails to report them. Doomsday scenarios of global warming are much more dramatic than the good news of global greening. — Keith E. Idso

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

We now know that we cannot continue to put ever-increasing amounts of CO2 into the atmosphere. Actions have consequences. In fact, the consequences of past actions are already in the pipeline. Global temperatures are rising. Glaciers are melting. Sea levels are rising. Extreme weather events are multiplying. — Cary Fowler

The warming we've experienced in the late 20th century could just as easily be explained by small decreases in cloud cover - natural changes in the system - and have nothing to do with CO2. — Willie Soon
