快速的碳循环案例如左下图所示。这一循环包括环境和生物圈中生命体之间相对短期的地球化学过程。它包括碳在大气以及陆地和海洋生态系统、泥土和海底沉积物之间的运移。快速循环包括涉及光合作用的年周期和涉及植被生长和分解的年代周期。快速碳循环对人类活动的响应将决定气候变化许多更直接的影响。<ref name=Bush2020 /><ref>{{cite journal |doi = 10.1073/pnas.022055499|title = Atmospheric carbon dioxide levels for the last 500 million years|year = 2002|last1 = Rothman|first1 = D.
