A climate scenario is a plausible representation of future climate.
It can be used to investigate the potential impacts of climate change.
What is a climate model simulation?
A climate model simulation is a representation of the real-world climate system, created using mathematical equations and solved on a computer. They are used to replicate the behaviour of the system under various conditions. The accuracy and utility of a model simulation depends on aspects including how natural climate variability is simulated, what emission scenario is used, the quality of underlying data and the validity of the assumptions made.
