Carbon Dioxide Quotes Page 2

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.

We have an atmosphere that is roughly 21% oxygen.

The rest of it is largely nitrogen. There's just enough carbon dioxide (CO2) to drive photosynthesis. That has been, throughout the history of our species, pretty stable. Until recently.

We have known since the 1800s that carbon dioxide traps heat in the atmosphere.

The right amount keeps the climate conducive to human life.

We have to, in the next ten years, begin to decrease the rate of carbon dioxide emissions and then flatten it out. If that doesn't happen in ten years, we're going to be passing certain tipping points. If the ice sheets begin to disintegrate, what can you do about it? You can't tie a rope around an ice sheet.

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.

There is no significant man-made global warming at this time, there has been none in the past and there is no reason to fear any in the future. Efforts to prove the theory that carbon dioxide is a significant 'greenhouse' gas and pollutant causing significant warming or weather effects have failed. There has been no warming over 18 years.

When I was a boy in the 1930s, the carbon dioxide level was still below 300 parts per million. This year, it reached 382, the highest figure for hundreds of thousands of years.

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.

Carbon dioxide is natural, it is not harmful, it is a part of Earth's lifecycle.

And yet we're being told that we have to reduce this natural substance, reduce the American standard of living, to create an arbitrary reduction in something that is naturally occurring in Earth.

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.

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.

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.

On the environmental front there's concern about global warming and high levels of carbon dioxide, and trees take in CO2 and store carbon.

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."

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.

Our early 21st century civilization is in trouble.

We need not go beyond the world food economy to see this. Over the last few decades we have created a food production bubble-one based on environmental trends that cannot be sustained, including overpumping aquifers, overplowing land, and overloading the atmosphere with carbon dioxide.

The simplest carbon dioxide removal approach is to plant a tree.

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.

The total efforts of the last 20 years of climate policy has likely reduced global emissions by less than 1 percent, or about 250 million metric tons of carbon dioxide per year.

At the moment, the 4 percent of us in this country produce a quarter of the world's carbon dioxide - once you look at maps of rising sea levels and spreading mosquitoes, you realize that we've probably never figured out a way to hate our neighbors around the world much more effectively.

The world has not warmed up very much since the millennium.

Twelve years is a reasonable time... it (the temperature) has stayed almost constant, whereas it should have been rising - carbon dioxide is rising, no question about that.

Alone among businesses, the fossil-fuel industry is allowed to dump its main waste, carbon dioxide, for free.

Each cylinder is about 10 percent ancient air, a pristine time capsule of greenhouse gases - carbon dioxide, methane, nitrous oxide - all unchanged from the day that snow formed and first fell.

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."

Climate is not responding to greenhouse gases in the way we thought it might.

If increasing carbon dioxide is in fact increasing climate change, its impact is smaller than natural variation. People are being misled by people making money out of this.

The Kyoto theorists have put the cart before the horse.

It is global warming that triggers higher levels of carbon dioxide in the atmosphere, not the other way round.

Education at school continues what has been done at home: it crystallizes the optical illusion, consolidates it with book learning, theoretically legitimizes the traditional trash and trains the children to know without understanding and to accept denominations for definitions. Astray in his conceptions, entangled in words, man loses the flair for truth, the taste for nature. What a powerful intellect must you possess, to be suspicious of this moral carbon dioxide and with your head swimming already, to hurl yourself out of it into the fresh air, with which, into the bargain, everyone round is trying to scare you!

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.

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.

Anything greater than 350 of parts of carbon dioxide per million is more than the planet can safely deal with. It is what's overwhelming our climate system. Because we've been going up about three parts per million per year. And eventually, we will always be above 410, and then above 420, and above 430. We just keep pouring more carbon into the atmosphere.

I think the deeper truth is that the Kyoto Protocols will not be followed by anyone really and that, in effect, nothing will be done to reduce carbon dioxide and other greenhouse emissions.

If NASA were advancing a space frontier there would be challenges you've never seen before. You have to be creative and you have to patent some new idea. You get to Mars...well, how do we get the water from the soil? I gotta invent a new device that will do that. And the carbon dioxide in the atmosphere, how can we use that? Can we breathe the oxygen from the carbon dioxide?

It was huge mistake to avoid working with the rest of the world because (a) we're the largest source of the problem: 4% of us who are in the U.S. produce 25% of the world's carbon dioxide.

We finally know where the red line for climate really is.

After the rapid melt of arctic ice in the summer of 2007, our best scientists, led by NASA's Jim Hansen, went back to work and produced a series of papers showing that with more than 350 ppm (parts per million) of carbon dioxide in the atmosphere, we couldn't have a planet "similar to the one on which civilization developed and to which life on earth is adapted."

I think natural gas has been a big part of the solution if in fact we need to reduce man-generated carbon dioxide emissions.
