Climate is a complex system that can be modelled.
A global climate model (GCM) uses hundreds of mathematical equations to describe processes that happen on our planet, like wind, ocean currents, and plant growth. Model is also used to describe how Earth processes are related to each other. All that helps scientists understand how Earth’s climate works and how climate is changing.

Large climate models are so complex that they need to be run on supercomputers. Usually this is done to make climate predictions for one or more centuries into the future. Sometimes models are run backwards to find out how climate may have changed in the past.
With today’s rate of pollution, there will be unpredictable events and climate will show extreme and unpredictable behaviour in an attempt to keep its equilibrium.
