The study of exoplanets has moved from an era of detection to an era of atmospheric characterisation, driven by the launch and commissioning of JWST as well as improvements in ground-based observational facilities. This era of characterisation will involve both deep studies of individual high signal-to-noise exoplanet atmospheres as well as shallow and broad studies of exoplanet atmospheric demographics. In this talk, I will describe how we can leverage both of these characterisation methods alongside 3D models to study exoplanet atmospheres. I will specifically describe the application of detailed 3D GCMs including the impact of clouds on the circulation and emergent properties of hot gas giant and potentially habitable rocky exoplanets. I will describe how the climate dynamics of temperate rocky exoplanets determine how planetary, atmospheric, and host star properties impact their potential for habitability. I will finish by describing the extent to which habitable conditions on rocky exoplanets may be discerned with future observations.
