In 1860 the percentage of carbon dioxide in the air was 278 ppm (parts per million), which is 0.0278%. This had been the average figure for the previous 2000 years of the pre-Industrial Age.
In 1900 it was 295 ppm.
In 1960 it was 315 ppm.
In 1980 it was 335 ppm.
In 1990 it was 350 ppm.
In 2000 it was 369 ppm.
In 2010 it was 388 ppm.
In 2011 it was 392 ppm. (March 2011)
This is an increase of 114 ppm, a 41% increase over the original 1860 amount.
Carbon dioxide
Since the original atmosphere, the gases which have decreased are water vapour and carbon dioxide and the gases which have increased are nitrogen, oxygen
Carbon Dioxide (CO2) levels in the atmosphere in 1750 were between 275 and 280 ppm (parts per million). In 2012 they were 396 ppm. That is a percentage increase of more than 40%. (41.4%, 280 to 394; 43.2%, 275 to 394) See the co2now.org site below.
Levels of carbon dioxide (CO2) in the atmosphere have increased rapidly since the beginning of the Industrial Revolution. Scientists agree that this is largely caused by burning fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity.
The carbon dioxide concentration has risen for numerous reasons, including the destruction of forests. The fewer trees and plants the are, the more carbon dioxide is the environment.

Levels of carbon dioxide in 1750 were approximately 275 parts per million. Today (2011) concentrations are approximately 392 ppm, an increase of more than 40 percent.

Ofcource you need carbon dioxide! Weather we like it or not, we produce it, since when we breathe, we take in oxygen, but when we breathe out, we take ou Carbon Dioxide!
there is no hydrogen in carbon dioxide. since carbon dioxide is CO2 there are 3 carbon and 6 oxygen atoms in three molecules.
In an atmosphere of carbon dioxide, warm carbon dioxide would rise. Since carbon dioxide is better than twice as dense as air, it would need to be really hot before it would rise.
Yes. In fact, burning fossil fuels is the principal way in which humans are increasing the atmospheric concentration of carbon dioxide, with the level going up by a startling 35 per cent since the Industrial Revolution.
Where there are no components, there is air when it is located on Earth's surface. Our air has some carbon dioxide in it. So there is some carbon dioxide in an ipod. It is not necessary to the function of an ipod. If you burn an ipod, some carbon dioxide will be released, since the casing has some carbon in it.
