Science Alert  June 19, 2023 Researchers in Portugal have shown that the impact of human activity on the Earth system could result in unpredictable chaos from which there is no return, physicists have calculated. Their 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. They found that the equilibrium point for temperature fluctuations can exhibit bifurcations and a chaotic pattern if the human […]
