Global warming modelling is a research field and methodological approach focused on developing and utilizing mathematical representations of the Earth's climate system to simulate and project future changes in global temperature and related climate variables. It investigates the complex interactions between atmospheric, oceanic, terrestrial, and cryospheric components, driven by natural and anthropogenic forcings, employing numerical models and computational simulations to understand past climate, attribute current changes, and forecast potential future warming under different emission scenarios, thereby providing critical insights for scientific assessment and policy formulation.
