Mars has a very thin atmosphere that is made mostly of carbon dioxide. About 95% of Mars' atmosphere is made of CO2. There are only traces of the other gasses in its atmospher â¦ e like nitrogen and carbon monoxide.  It's atmospheric pressure is 7-9 milibars, depending on the season.
While Mars's climate has similarities to Earth's, including periodic ice ages, there are also important differences, such as much lower thermal inertia. Mars' atmosphere has a scale height of approximately 11 km (36,000 ft), 60% greater than that on Earth. The climate is of considerable relevance to the question of whether life is or was present on the planet.
