Water issues are notoriously difficult for California governors. Just look at former Gov. Jerry Brown’s floundering tunnels proposal for the Sacramento-San Joaquin River Delta. Yet two factors suggest that Gov. Gavin Newsom must make water a priority. First, California needs more climate-resistant water supplies. Climate change is making California’s weather more extreme. For the past decade, most years have brought drought or the risk of catastrophic floods. And looking forward, scientists warn that climate change will reduce the water we get from our rivers.
