380-400 ppm
The atmosphere of Mars is almost entirely CO2.
Volcanos release sulfur dioxide, carbon dioxide, and ash to the atmosphere at the same time
Plants use carbon dioxide, so there is less carbon dioxide in the atmosphere in the summer.
Because trees remove carbon dioxide from the atmosphere, and if they cut them down we will have more carbon dioxide.
carbon dioxide contains about 27.27% carbon.
Jupiters upper atmosphere is mainly carbon dioxide and nitrous oxide below that is a layer of condensed hydrogen or a sea of hydrogen because of the immense pressure in the atmosphere
The percent of the atmosphere made out of carbon dioxide is 0.038.
Mars has an atmosphere of about 95.72% carbon dioxide. Venus has an atmosphere of about 96.5% carbon dioxide

venus atmosphere of carbon dioxide is 96.5%

The atmosphere on Venus is very thick and comprised of 96 percent carbon dioxide. About 3.5 percent of its atmosphere is nitrogen and 0.5 percent is comprised of other gases.
Venus has 96 percent of carbon dioxide
Carbon dioxide has a concentration of 0,039445 %.
The atmosphere of Mars is almost entirely CO2.
In 2014 carbon dioxide levels are around 400 ppm (parts per million) or 0.04%.
The martian atmosphere is composed of five main gases, with carbon dioxide making up 95.32% of the atmosphere. Other gases include:Nitrogen - 2.7%Argon - 1.6%;Oxygen - 0.13%;Carbon Monoxide - 0.08%
