How does climate change impact California's water resources?

Climate change significantly impacts California's water resources primarily by altering precipitation patterns and increasing the frequency of droughts. Due to rising temperatures, the state experiences shifts in the timing and intensity of rainfall. This means that while some areas might see more rain, others may endure prolonged dry periods. The overall climate change trend leads to more variable weather patterns, making it difficult for water management systems to adapt.

As droughts become more frequent and intense, the water supply becomes less predictable, further taxing reservoirs, groundwater sources, and the overall water infrastructure. This not only affects agricultural practices but also influences urban water supply and the ecological health of rivers and wetlands. Understanding these dynamics is essential for developing effective policies and strategies to manage water resources in a rapidly changing climate.

In contrast, options suggesting consistent rainfall or minimal impacts on water usage do not align with the observable trends linked to climate change. Additionally, the reduction of cross-border water conflicts does not directly reflect the challenges presented by climate change but rather shifts the focus of water management policy.
