Less than six months into his second term as president, Donald Trump has initiated or proposed more than 150 actions that experts say are detrimental to the environment, which range from cancelling climate grant programs to loosening regulations that govern air and water quality. Many of these actions have been part of the president’s larger goals of reining in government spending, increasing energy independence and restructuring federal agencies. But some also appear to target one state in particular: California. Long known as a nationwide leader in climate and environmental policy, the Golden State has been in Trump’s crosshairs since his first administration, when he sparred with Gov. Gavin Newsom over issues such as forest and water-supply management.
