Current climate models are complex computer programs that are typically iterated time-step by time-step to predict the next set of values of the climate-related variables.

In particular, we apply the constraint database approach to software verification to find that the rise in global temperature is bounded according to the common Java Climate Model that implements the Wigley/Raper Upwelling-Diffusion Energy Balance Model climate model.
