  4. Release associated with 10.2138/gselements.19.5.296 publication. This repository hosts a notebook that implements the 0-D energy balance model of Pierrehumbert et al. (2011). It utilizes the Python script published by Pierrehumbert et al. (2011) which itself uses the ClimateUtilities modules. A run of the model with slightly modified variables is visualized in a simplified plot of just the upper and lower limb without showing the unstable branches. In addition, CO_2 decrease scenarios are shown (2 CO_2 halvings) starting at different initial global mean temperatures. These scenarios illustrate that the effect of a decrease in CO_2 (say driven by changing paleogeographic boundary conditions) on Earth's climate state will be quite different depending on the initial starting condition.
