Carbon Dioxide Quotes

Putting aside for the moment the question of whether human industrial CO2 emissions are having an effect on climate, it is quite clear that they are raising atmospheric CO2 levels. As a result, they are having a strong and markedly positive effect on plant growth worldwide. There is no doubt about this.

…trees are made of air, primarily. When they are burned, they go back to air, and in the flaming heat is released the flaming heat of the Sun which was bound in to convert the air into tree. And in the ash is the small remnant of the part which did not come from air, that came from the solid earth, instead.

By enriching the carbon-dioxide content of the atmosphere from its impoverished pre-industrial levels, human beings have increased the productivity of the entire biosphere - so much so that roughly one out of every seven living things on the planet owes its existence to the marvelous improvement in nature that humans have effected.

We must act to reduce the increasingly dangerous and destructive levels of carbon pollution that account for practically all of global climate change.

From the best of the collective work, we believe that burning natural gas for electricity produces about 30-50% less greenhouse gas than burning coal, even accounting for the emissions of methane (and carbon dioxide) from producing and transporting the natural gas.

The causal chain of the deterioration (of the environment) is easily followed to its source. Too many cars, too many factories, too much detergent, too much pesticide, multiplying contrails, inadequate sewage treatment plants, too little water, too much carbon dioxide---all can be traced easily to too many people.

Places that have become agricultural deserts, trashed by giant corporations, could be reforested, drawing carbon dioxide from the air on a vast scale. The ecosystems of land and sea could recover, not just in pockets but across great tracts of the planet.

There is universal consensus among experts that the earth's atmosphere is heating up - and that we are responsible for it by putting carbon dioxide in the atmosphere. We also know that the consequences of global warming are catastrophic. But how do we make sure that all countries reduce greenhouse gases?

We have fans that circulate air in the cabin of the module of the space shuttle. They're running all the time. They're absolutely necessary because, otherwise, you will breathe your own CO2 and intoxicate yourself quite fast.

The carbon dioxide concentration in the atmosphere is measured. It's uncontroversial. It's going up. We know that has a tendency to warm the atmosphere and we should be worried about that.

I called their attention also to the absence of all means of ventilating the hall, remarking that, as we had already breathed the air which it contained for a full hour, it must have lost much of its vital properties and needed to be renewed.

I remember, as a boy of 17 years of age, this was a fascinating thing for me: how we human beings breathe out carbon dioxide into the air, the leaves of plants pick this carbon dioxide up, and the plant gives off oxygen, which we can breathe in and keep our life going.

Now, we put out a lot of carbon dioxide every year, over 26 billion tons. For each American, it's about 20 tons. For people in poor countries, it's less than one ton. It's an average of about five tons for everyone on the planet. And, somehow, we have to make changes that will bring that down to zero.

An acre of corn, one of the rare plant species to use a carbon dioxide efficient photosynthesis system, removes more carbon dioxide from the atmosphere than does an acre of mature Amazonian rain forest…

In the course of the 1920s and 1930s, great progress was made in the study of the intermediary reactions by which sugar is anaerobically fermented to lactic acid or to ethanol and carbon dioxide.

Few scientists now dispute that today's soaring levels of carbon dioxide and other gases in the atmosphere will cause global temperature averages to rise by as much as nine degrees Fahrenheit sometime after the year 2000.

Now air is the cause and spirit of every life and motion in the world, be it in flesh or in any of the vegetables; all whatever is hath its life from the air, and nothing whatsoever that moveth and is in this world can subsist without air.

Air is one we hold in common; it has a limited carrying capacity for pollutants and that's being used up by those who pollute the atmosphere. So we have to stop that externality. We would never allow a utility to put their coal slag in a dump truck and back it up to the city park and dump it in unlimited amounts for free. But that is exactly what we do with carbon dioxide and methane.

Plate tectonics is not all havoc and destruction. The slow movement of continents and ocean floors recycles carbon dioxide dissolved in the oceans back into the atmosphere. Without this slow speed carbon cycle, Earth's temperatures would cool dozens of degrees below your comfort zone.

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.

You could warm Mars up, over time, with greenhouse gases.

We are now beyond nature's normal variation in terms of how the atmosphere is composed. Nature did something for a million years. It actually goes back a lot further than that, but the ice core records show a million years. So, nature has this normal oscillation within this zone, and all of a sudden, we're forty percent outside that zone.

Coal fired power plants emit particulates which cause respitory problems.

China may achieve its goal of reducing the carbon intensity of its economy (the ratio of carbon dioxide emissions per unit of output) by 45 percent below its 2005 level by 2020. But the country is growing so fast that its coal consumption and greenhouse gas emissions are expected to continue to increase. China is expected to add the equivalent of a new 500-megawatt coal-fired electric plant every 10 days for the next decade...

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.
