FRIEDMAN: But what we do know is this, Christiane, and this is really important. We know the gases we put up there stay there for like 3,000 years. In other words, they're irreversible.

CO2 residence time: Does it really "stay there for like 3,000 years"?

Sundquist (1985) compiled a large number of measured RTs of CO2 found by different methods. The list, containing RTs for both 12CO2 and 14CO2, was expanded by Segalstad (1998), showing a total range for all reported RTs from 1 to 15 years, with most RT values ranging from 5 to 15 years.
