A Simple Model for Climate Bifurcation: https://arxiv.org/abs/1907.11067
In this paper we present (for educational purposes) a simple one dimensional model for the mean temperature of the Earth. The model can exhibit bifurcations from the present Earth climate to an ice age or a "Venus type of climate". The model is accompanied by a Matlab program which enable the user to experiment by changing the model parameters and explore the impact that these changes might have on the Earth climate.
