Climate change will significantly affect the future hydrological cycle over land, with major implications for water availability for ecosystems and anthropogenic use in regions that already face severe water scarcity. Previous assessments of these hydrological changes inform about shifts under different future warming scenarios. However, there is a lack of understanding in the response of land surface water availability after temporary temperature overshoot scenarios that consider carbon dioxide removal techniques with the aim to reverse warming, which bear the risk of causing irreversible shifts in regional hydrological cycles. In this presentation, I will talk about the reversibility of annual and seasonal shifts in land surface water availability defined as precipitation minus evaporation (P-E) in an ensemble of simulations from the Carbon Dioxide Removal Intercomparison Project.
