User: how often is carbon dioxide cycled throught the atmosphere?

Weegy: Individual carbon dioxide (CO2) molecules spend an average of 3-4 years in the atmosphere (the residence time), before moving on as part of the carbon cycle. [ However, because CO2 leaving the atmosphere is offset by CO2 from natural carbon sources, it takes a lot longer than this for artificial CO2 increases to dissipate - up to a thousand years. This is called the turnover time, or the global atmospheric lifetime. ]
