作者模拟了地球化学过程在陆地、海洋和大气之间转移碳的缓慢而长期的循环。该模型表明，过去大气中二氧化碳的积累增强了温室效应，地球可能已经变暖了。该模型预测，大气二氧化碳缓慢的自然波动可能与人类活动或生物碳循环引起的更快的变化相媲美，甚至超过这种变化。模拟地球化学碳循环的主要目的是揭示对重要全球过程的速率知之甚少，以及表面上不相关的过程（如构造和气候）是如何联系在一起的。
The authors have modeled the slow, long-term cycle in which geochemical processes transfer carbon among land, sea, and atmosphere. The model suggests that the earth may have been warmed in the past when buildups of atmospheric carbon dioxide enhanced the greenhouse effect. The model predicts that the slow natural fluctuations of atmospheric carbon dioxide may rival or even exceed the much faster changes that arise from human activities or from the biological carbon cycle. The main purpose in modeling the geochemical carbon cycle is to expose how little is known about the rates of important global processes and how seemingly unrelated processes (such as tectonism and climate) are linked.
