Water is core to California’s way of life.

But as climate change causes more volatile precipitation, less snowpack, more flooding, higher temperatures, and shorter wet seasons, the water system will increasingly fail to meet the needs of California’s communities, industry, and agriculture.

New analysis by the Union of Concerned Scientists shows that the data and certainty needed to quantitatively plan for climate change in California water management are available now.

This report outlines the key shifts in California’s hydroclimate; illustrates the risks for California’s residents, businesses, and agriculture if these shifts are ignored; and describes how the state can jumpstart the comprehensive climate planning that is needed.
