The effect of variations in cloud cover, optical properties, and fractional distribution with altitude on the mean surface temperature of a model of the early earth has been investigated. In all cases examined, cloud-climate feedbacks result in temperatures greater than those in models with no cloud feedbacks. If the model of hydrospheric feedback effects is correct, then cloud feedbacks are as important to the climate as changes in solar luminosity and atmospheric composition during the earth's atmospheric evolution. In particular, the early earth need not become completely ice-covered if strong negative cloud feedbacks occur. However, until a proper understanding of cloud feedbacks is available, conclusions regarding conditions in the early atmosphere must remain in doubt.
研究了云层覆盖、光学特性以及随海拔高度的分数分布变化对早期地球模型平均地表温度的影响。在所研究的所有情况下，云 - 气候反馈导致的温度高于无云反馈模型中的温度。如果水圈反馈效应模型正确，那么在地球大气演化过程中，云反馈对气候的重要性等同于太阳光度和大气成分的变化。特别是，如果出现强烈的负云反馈，早期地球不一定会完全被冰覆盖。然而，在对云反馈有恰当理解之前，关于早期大气状况的结论仍存疑。
