The carbon Dioxide levels in the Earth's atmosphere are rising.
In pre-industrial times, the amount of carbon dioxide (CO2)that animals breathe out was matched by the amount absorbed by plants, so that the concentration of atmospheric carbon dioxide remained remarkably stable in the range of 260 to 280 parts per million (ppm) over a very long period. Adding additional carbon dioxide by burning fossil fuels, overwhelms the carbon cycle and causes the atmospheric concentration of carbon dioxide to rise beyond this range. Deforestation can break the carbon cycle, first by removing a store of carbon which will be released as additional carbon dioxide into the atmosphere, and in some cases by reducing the ability of nature to absorb carbon dioxide from the air.
This gas is carbon dioxide: 0,039 445 %.
Green plants take carbon dioxide from the atmosphere, and using energy from the sun separate the carbon from the oxygen. They release the oxygen to the atmosphere, and use the carbon.
Carbon-Dioxide.
Forest fires increase the amount of carbon dioxide in the atmosphere

Assuming you mean "carbon dioxide", the atmosphere of Venus is made up mainly of carbon dioxide.

The present levels of carbon dioxide dioxide in the atmosphere are causing global warming and climate change.
