What is one potential impact of climate change on water supply?

One significant potential impact of climate change on water supply is the increased frequency and severity of droughts affecting water availability. As global temperatures rise, the atmospheric conditions can lead to changes in precipitation patterns, which often manifest as extended periods of drought in various regions. These droughts can reduce surface water and groundwater supplies, impacting agricultural irrigation, drinking water supplies, and natural ecosystems that rely on consistent water flow.

During drought conditions, the demand for water often remains the same or even increases, while the availability diminishes, leading to competition for limited resources. This can exacerbate existing water scarcity issues and pose challenges for water management and planning. It’s also important to note that while some areas may experience increased precipitation, the overall trend of climate change correlates with more frequent and severe droughts in many regions, making this option the most accurate portrayal of climate change's impact on water supply.
