It is well known that climate system is complex, unpredictable and chaotic. In this project,
we consider a Lorenz system namely the Earth’s Climate System (ECS) model on how it
related to the climate change. The objectives of this project are to investigate the
behaviour of ECS model over time by using time series, to examine the stability of
equilibrium point at ECS model by using stability analysis, and to study the sensitive
dependence on initial condition of the model. Our results showed that the time series plot
obtained for ECS model can be used to predict the behaviour of climate system. Thus,
for stability analysis results, we obtained that the equilibrium points are saddle and thus
unstable. Finally, we have shown that ECS model is sensitive to different initial condition
and this indicates that this model has chaotic behaviour.
