一个教学用的"玩具"气候模型
A Pedagogical "Toy" Climate Model
摘要：
一个"玩具"模型，足够简单和基本的本科班，温室（中红外）吸收大气水蒸气的温度依赖性意味着一个温室气候系统。稳定状态是冰期和温暖的间冰期，而中间状态是不稳定的。这与古气候资料定性一致。目前的气候可能是不稳定的，有或没有人为干预，如CO $_2$排放，除非有额外的稳定反馈，如"地球工程"。
英文摘要：
A "toy" model, simple and elementary enough for an undergraduate class, of the temperature dependence of the greenhouse (mid-IR) absorption by atmospheric water vapor implies a bistable climate system. The stable states are glaciation and warm interglacials, while intermediate states are unstable. This is in qualitative accord with the paleoclimatic data. The present climate may be unstable, with or without anthropogenic interventions such as CO$_2$ emission, unless there is additional stabilizing feedback such as "geoengineering".
