Report presents an integration of water withdrawal projections and future estimates of renewable water supply across the US to assess future water availability in the face of a changing climate. The analysis is performed using annual water use data at the county level, and using global climate model outputs for temperature and precipitation, both projected 20-40 years into the future. Report indicates that water supplies in 70% of counties in the US may be at risk to climate change, and approximately one-third of counties may be at high or extreme risk.
