Chaotic Behaviour of the Earth System in the Anthropocene
It is shown that the Earth System (ES) can, due to the impact of human activities, behave in a chaotic fashion.
Our arguments are based on the assumption that the ES can be described by a Landau-Ginzburg model, which on its own allows for predicting that the ES evolves, through regular trajectories in the phase space, towards a Hothouse Earth scenario for a finite amount of human-driven impact.
Furthermore, we find that the equilibrium point for temperature fluctuations can exhibit bifurcations and a chaotic pattern if the human impact follows a logistic map.
