In what way can climate change affect water supply systems?

Climate change can significantly affect water supply systems by altering precipitation patterns and increasing the frequency and severity of extreme weather events. As global temperatures rise, the dynamics of the hydrological cycle change, leading to variations in rainfall distribution. Some regions may experience more intense rainfall events, resulting in flooding, while others may encounter prolonged droughts. This variability directly impacts the availability and reliability of freshwater sources.

Furthermore, extreme weather events such as hurricanes, storms, and heatwaves can damage existing water infrastructure, disrupt supply chains, and compromise water quality, making it harder to ensure a consistent and safe water supply. These challenges necessitate adaptive management strategies to address the unpredictability of water resources due to climate impacts, highlighting the critical nature of understanding these changes when planning and managing water supply systems.
