Abstract

Climate change is profoundly altering the global hydrologic cycle, affecting the movement, storage, and quality of water across atmospheric, terrestrial, and aquatic systems. Rising global temperatures, changing precipitation patterns, increasing atmospheric evaporative demand, and intensifying hydroclimatic extremes are reshaping key hydrological processes, including evapotranspiration, soil moisture dynamics, runoff generation, streamflow regimes, groundwater recharge, and water quality. This review synthesizes recent advances in understanding the impacts of climate change on the hydrologic cycle, drawing upon contemporary literature published between 2023 and 2026. The review examines how warming-induced changes in atmospheric moisture transport and precipitation variability are increasing the frequency and intensity of floods, droughts, heatwaves, and compound hydroclimatic events. It further explores the implications of climate change for groundwater sustainability, freshwater ecosystems, water quality, and ecosystem services. Emerging evidence indicates that climate change is not only intensifying the hydrologic cycle but also increasing its spatial and temporal variability, thereby increasing uncertainty in water availability and resource management. The review highlights major research gaps related to groundwater–climate interactions, compound extremes, human–water feedback, and ecosystem resilience. Additionally, it evaluates adaptation and mitigation strategies, including integrated water resources management, nature-based solutions, climate-smart agriculture, sustainable groundwater management, and the application of artificial intelligence and digital-twin technologies for climate-resilient water governance. The findings emphasize that future water security will depend on integrating scientific innovation, adaptive management, and policy interventions to address increasingly non-stationary hydrological conditions. Strengthening interdisciplinary research and climate-informed water management frameworks will be essential for enhancing resilience and ensuring the sustainable use of freshwater resources in a rapidly changing climate

Keywords: Precipitation variability, groundwater recharge, hydroclimatic extremes, water quality, climate resilience, water security, digital twins
