Conversation so far:
what is the approximate atmospheric life of co2
The lifetime in the air of CO2, the most significant greenhouse gas, is the most difficult to determine, because there are several processes that remove carbon dioxide from the atmosphere.
what is the most common process in which carbon dioxide is removed from the atmosphere
Between 65% and 80% of CO2 released into the air dissolves into the ocean over a period of 20–200 years.

Question: how long do other process take
Self-contained rewrite: how long do other processes in which carbon dioxide is removed from the atmosphere besides dissolving into the ocean take
