Climate models are used to predict how the climate will change in the future .
But what is the climate?
The climate is a system which involves the atmosphere, oceans, ice, soil, and all living things on Earth . It changes constantly due to interactions between these different parts within the climate system [2,3] e.g. trees releasing water into the atmosphere leading to increased rainfall in those areas .
The climate can also be forced to change by adding outside “forcings”  such as volcanic eruptions  or increased CO 2 emissions  .
Climate models make predictions by simulating these interactions, feedbacks and forcings . To do this scientists must represent these processes using complex scientific equations [8,9,10]. For example, some equations will be based on balancing the energy [9,10] from the sun with the energy absorbed or reflected by the earth and atmosphere .
Climate scientists make future predictions using their climate models by putting expected values of CO 2 emissions and other variables into the equations .
