In earth's atmosphere carbon dioxide comprises only 400 parts per million, of which roughly 280 ppm derived from natural sources. CO2 is a heat trapping gas, and increasing the concentration of it results in global warming. In under 40 years we will pass 500 ppm, while many scientists believe 350 ppm may be the maximum sustainable level.
CO2 is, of course, necessary for plant life. Plants break the CO2 apart during photosynthesis, releasing O2 back into the atmosphere. Some studies show plant life might benefit from slightly higher concentrations of CO2, though most terrestrial plants spent the past 20 million years adapting to levels ranging from 250 to 280 ppm.
Other than that, CO2 is fairly inert, having little atmospheric impact other than that of absorbing heat as noted.

What does the increase of carbon dioxide in the air mean?
It means that there is more carbon dioxide (unbreathable air) gets in to are air
Is carbon dioxide air pollution why?
Carbon dioxide is not an air pollutant. However excessive carbon dioxide release into the atmosphere is a pollutant as it contributes to acid rain
Does respiration add carbon dioxide to the air?
Yes, respiration does add carbon dioxide to the air
How is carbon dioxide released into the air by carbonate rocks?
When acid rain reacts with the carbonate rocks, carbon dioxide is usually released into the air.
What percent of expired air is carbon dioxide?
Approximately 4-5% of expired air is carbon dioxide
Does carbon dioxide dissolve into air?
Carbon dioxide IS air
What is the impact of the pollution in china?
it is a huge impact because of all the industrial buildings and factories causing carbon dioxide which is polluting the air
Is carbon dioxide than air?
Carbon dioxide is more dense than air.
Do autotrophs remove carbon dioxide from the air?
do autotrophs remove carbon dioxide from the air
What is the carbon dioxide?
carbon dioxide is a air which comes from the plants
What does the increase of carbon dioxide in the air mean?
It means that there is more carbon dioxide (unbreathable air) gets in to are air
Does carbon dioxide come from water?
Carbon Dioxide is the air we breathe out. :)
During photosynthesis plants use what as a carbon source to produce sugars for energy?
The Carbon source for photosynthesis is the air
Is carbon dioxide air pollution why?
Carbon dioxide is not an air pollutant. However excessive carbon dioxide release into the atmosphere is a pollutant as it contributes to acid rain
Does respiration add carbon dioxide to the air?
Yes, respiration does add carbon dioxide to the air
How does plants get the carbon dioxide?
Plants get carbon dioxide from the air we exhale. We breath out carbon dioxide and plants give us oxygen. So when we breath oxygen the air that we exhale is carbon dioxide that goes to plants.
What is the source of the carbon in the sugars made by plant's?
Carbon Dioxide (CO2) from the air.
