One of the objectives of studying exoplanets is to discover surface liquid water, a sine qua non condition for the existence of life as we know it. Temperate terrestrial planets are very challenging targets, even for JWST. However, their detection is a major objective for PLATO, and their characterization is one of the aims of many other future missions such as RISTRETTO@VLT, ANDES@ELT, PCS@ELT, HWO and LIFE. To prepare these instruments for this science goal, it is necessary to improve our knowledge of habitability using climate modeling. First, I will present the current stage of knowledge regarding the limits of habitability, defined as a planet sustaining surface liquid water. Second, knowing that one of the aim of HWO and LIFE is to detect biosignatures, I will highlight the remaining challenges to bridging the gap between theory and constrains on the target selection.
