How much CO2 is there at any one time in the atmosphere?
CO2 provides approximately .03% of the earth's atmosphere. If you consider that the earth's atmosphere contains approximately 4.2 billion cubic kilometers - which is the "effective mass" of the atmosphere, or the mass of the entire atmosphere if measured at sea level pressure - then: 4.2 billion x .03 % = 1,260,000 cubic kilometers of CO2. The other constant used in this equation is the "Karman Limit" of 100 miles as the upper boundary for earth's atmosphere.
How old is the atmosphere?
The Earth is about 4.5 billion years old and has had an atmosphere since it formed, but about 3.8-4.1 billion years ago there was believed to be the Late Heavy Bombardment, where a planetesimal roughly the size of Mars hit the Earth, breaking off a large chunk that formed into the Moon. This impact would have obliterated the atmosphere, but it has reformed naturally since then. So, the answer to your question is approximately 4 billion years old.
