California water supplies may drop 23% in 20 years

California's State Water Project may see water supplies decrease by up to 23% over the next 20 years due to climate change, according to projections from Gov. Gavin Newsom's administration. The analysis indicates that rising temperatures and changing precipitation patterns could significantly impact water delivery, affecting 27 million residents and 750,000 acres of farmland. The report highlights the need for infrastructure upgrades to adapt to these changes.
