Abstract: In economics literature, the climate system is often modeled by a linear system, mostly because of its simplicity. In reality, however, the climate system responds to anthropogenic carbon emission in a much more complex manner, especially when it is stretched beyond capacity. In this paper, I develop an analytic integrated assessment model which allows for a non-linear response of climate system to carbon emission. The model is highly tractable and both the optimal solution and the non-cooperative equilibrium can be characterized in a transparent way. Differences between linear and non-linear climate systems are highlighted. I use the model of non-linear climate system to investigate a number of important climate policy issues, including the optimal carbon price and the consequences of unsuccessful international climate cooperation.
