The response of the Earth’s hydrological cycle to global warming is a topic of interest for RSE, as the energy system depends heavily on weather conditions. Since critical infrastructures have lifespans of several decades, the aim of the study (https://www.mdpi.com/2073-4441/13/10/1335) is to provide updated projections, on a seasonal scale, relative to the rainfall regime for Italy. Based on a set of Euro-CORDEX models (spatial resolution of approximately 12 km), under three different radiative forcing hypotheses (RCP8.5, RCP4.5 and RCP 2.6), several short-term (2021- 2050), medium-term (2041-2070) and long-term (2071-2100) climate scenarios were developed to characterize, in particular, dry conditions and extreme precipitation using two ETCCDI indices (CDD and R99PTOT). Despite some uncertainties (related to certain discrepancies between models), an exacerbation of dry periods and extreme precipitation in the coming decades is very likely under a business as usual hypothesis (RCP 8.5). These conditions will be less critical if partial mitigation actions are undertaken (RCP4.5) and will be significantly reduced with decarbonization policies (RCP 2.6).
