No.

Carbon dioxide levels in the atmosphere 2000 years ago were around 280 ppm (parts per million) and remained around that level till about 1800, when we started burning coal. Levels now (2013) are approaching 400 ppm.

Is there more carbon dioxide in Pepsi or 7up?

it has more carbon dioxide in 7up because it is stronger than a pepsi and if you look at a bottle you will see that it has more carbon dioxide


What does exhaled air contain more of than inhaled air?

More Oxygen, because some of it is processed into Carbon Dioxide (CO2).


Why has the carbon dioxide level of the atmosphere been rising for more then 150 years?

The increase in atmospheric carbon dioxide levels over the past 150 years is primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release more CO2 than natural sinks can absorb, leading to a build-up of carbon dioxide in the atmosphere.


What generalization can you make about the relationship of temperature to the amount of carbon dioxide in the air?

The more carbon dioxide in the atmosphere, the higher the temperature.


What might decrease global atmospheric carbon dioxide?

There is no known way that humans can economically remove carbon dioxide from the atmosphere; all we can really do is reduce our emissions of carbon dioxide and slow down the rate at which atmospheric carbon dioxide levels are increasing. The surface waters of the ocean do absorb some carbon dioxide from the atmosphere as atmospheric carbon dioxide level increase, but there is little interchange betwen the warm upper ocean and the deep layers. However over a period of several thousand years, there is sufficient interchange to absorb large volumes of carbon dioxide, allowing the atmospheric concentration to return more or less to normal. Afforestation. Planting trees will remove carbon dioxide from the atmosphere.

Why is there more carbon dioxide in Earth's atmosphere?

There is more carbon dioxide in the atmosphere now because we have been burning fossil fuels (coal, oil and natural gas) for more than 200 years. This burning adds long-hidden carbon dioxide, so it is too much for the carbon cycle to completely recycle.


What gas in the atmosphere is suspected to be contributing to global warning?

Carbon dioxide, and it's more than "suspected". Scientists have known that carbon dioxide traps heat for more than 200 years.

Does exhaled air contain more carbon dioxide or oxygen?

Carbon dioxide.


Is there more carbon in carbon dioxide or carbon monoxide?

There is proportionally more carbon in carbon monoxide than there is in carbon dioxide. Carbon monoxide, CO, has a one-to-one ration of carbon to oxygen. Carbon dioxide, CO2, has a one-to-two ration of carbon to oxygen.


Is carbon dioxide than air?

Carbon dioxide is more dense than air.

Does more heat mean more carbon dioxide in the atmosphere?

The more carbon dioxide the hotter the planet gets. The hotter the planet gets the more wild fires happen. For every fire that occurs more carbon dioxide is released.

Would taking more flights reduce carbon dioxide?

Flying generally consumes fuel and therefore emits carbon dioxide. Even birds exhale more carbon dioxide when they are flying. Helium baloons can fly without emitting carbon dioxide, however.
