CO2 is a heat trapping, "greenhouse gas" (GHG). It is thought that 350 ppm (parts per million) of CO2 should be sustainable (not contribute significantly to global warming). We are currently almost 400 ppm, and will exceed 500 ppm at the current rate of consumption in less than 40 years (by 2050).

Where is carbon in the atmosphere mostly found?
Carbon Dioxide at .033% The only other two sources in the atmosphere are methane and carbon dioxide both of which are much less abundant.
Is there more nitrogen or carbon dioxide in earth's atmosphere?
There is much more nitrogen in earth's atmosphere than carbon dioxide. Nitrogen forms about 79%, while carbon dioxide makes up about 0.04%.
What happens when the atmosphere has a higher percentage of carbon dioxide and lower oxygen?
The Earth will become hotter as carbon dioxide traps heat to keep the Earth warm. But too much carbon dioxide will cause the Earth to be more warm and that lead to global warming.
Which processes in the carbon cycle decreases the amount of carbon dioxide in the atmosphere?
Plants and trees remove carbon dioxide from the atmosphere through photosynthesis. The ocean also absorbs carbon dioxide, so much now that it is becoming more acidic.
Will planting trees improve carbon dioxide levels?
In the short term, yes. As the trees grow, they sequester carbon from the carbon dioxide in the atmosphere by turning it into wood. However, when the tree dies and decays or burns, much of that carbon returns to the atmosphere as carbon dioxide.
What planet's atmosphere is most carbon dioxide?
There are two such planets, Mars and Venus. Venus has a much thicker atmosphere than Mars, but both atmospheres are about 95% carbon dioxide.
Does Mars have am atmosphere?
Yes, but it is much thinner than Earth's atmosphere, and has considerably more carbon dioxide.
What gas in the atmosphere was absorbed by the oceans as they formed?
The ocean water absorbed much of the carbon dioxide from the atmosphere.
How does carbon and the atmosphere interact?
The carbon cycle moves carbon in and out of the atmosphere, the land, plants and animals, and the oceans. Carbon dioxide in the atmosphere is a greenhouse gas that keeps the planet warm. Too much carbon dioxide in the atmosphere, from humans adding it by burning fossil fuels, is causing an accelerated greenhouse effect, global warming.
Is The atmosphere stores much more carbon dioxide than the oceans?
False.
How much more carbon dioxide is there than oxygen?
There is 21% oxygen in the atmosphere and 300 ppm (0.03%) carbon dioxide. This translated to 700 times more oxygen than carbon dioxide.
Which planet has a thick atmosphere which is mainly composed of carbon dioxide?
The atmosphere of Venus is the layer of gases surrounding Venus. It is composed primarily of carbon dioxide and is much denser and hotter than that of Earth.
