Using real-world climate data
Games like Fate of the World use real-world climate data (IPCC models) to show the long-term, often irreversible consequences of policy decisions on global temperature and GDP. This could also include the use of real-world climate models, likely in an abstracted, more accessible form, to determine in-game events. This is still comparatively rare; for example, the board game Daybreak incorporated insights from climate science like the concept of tipping points into its gameplay (https://meetingorganizer.copernicus.org/EGU24/EGU24-8162.html). The serious game Adaptive Futures, created in Twine (https://niwa.co.nz/hazards/adaptive-futures-serious-game-climate-change-adaptation), also relies on simple climate models to simulate the transformation of a coastal community in the face of rising sea levels, though the output of the model can often feel rather arbitrary, which may easily reduce trust in the accuracy and explanatory potential of the underlying model.
