Climate models are computer programs that simulate the behaviour of the Earth's climate system. They work by representing the Earth as a set of grid boxes or cells. The models use mathematical equations to simulate how these variables interact with each other over time. They differ from weather forecasting in time scale, spatial scale and input data. From climate models, we have developed Shared Socioeconomic Pathways (or SSPs), which are scenarios used in climate modelling that describe different possible trajectories of global socioeconomic development over the next few decades. SSPs provide a common framework for exploring the relationship between different climate change mitigation and adaptation policies and socioeconomic development.
Key learning objectives:
Define the purpose of climate models
Understand difference between climate models and forecasting
Outline the Shared Socioeconomic Pathways (SSPs)
