In the study of small terrestrial planets, the runaway greenhouse is of great importance by separating two drastically different populations: temperate habitable planets and hot water-rich uninhabitable planets. It also delimits the inner edge of the habitable zone, that is a simple but powerful tool to study large samples of targets. It is one of the key processes that we need to understand preparing the future missions that aim to detect and characterize small terrestrial planets (e.g. PLATO , Life, HWO ).

In this presentation, we will discuss the limits of habitability using climate modeling (1D and 3D) to try to build a comprehensive overview of the intrinsic complexity of this topic. We will see the implications of the runaway greenhouse, but also how the different 3D processes happening in the atmosphere could induce various climates for this type of planet, through climate multistability for instance.
