For helping scientist and researchers around the world in understanding how the climate was thousand years ago and in predicting the climate of the future we use climate model, which are tools for understanding the climate of the Earth. The base of climate models is that it uses different equations to represent interactions and various processes that change the Earth’s climate. The models follow the fundamental laws of physical, biological and chemical mechanisms taking place in the Earth. There are different types of climatic models: Box models, Radiative-convective models, EMICs and GCMs. There are various institutions were climatic models are made, implemented and are used. By attending the conference on Climate Change 2019 we will have a clear concept about the climatic models and its working principle and role in forecasting the future climate.
