The cost and ability of California’s water supply system to adapt to major changes in climate are assessed using the CALVIN economic-engineering model. A dry climate warming GCM scenario is used to create statewide hydrologic changes, which are combined with 2050 water demands in the model. Results indicate that dry climate warming could have significant economic effects on California’s water supply, particularly for some agricultural areas. However, a portfolio of water management adaptations allows the magnitude of these economic impacts to be small compared with the overall state economy.
