Jerry Brown's trip to China earned him wall-to-wall media coverage - internationally and here at home. Much less covered was another environmental visit the governor took just weeks earlier: to Bell Gardens in Los Angeles County, a transportation corridor with some of the worst air quality in the state. Those two trips highlight competing tensions as Brown seeks to shape climate change policies in California and around the world. When Capital Public Radio's Ben Bradford interviewed the California governor during a car ride in Beijing last week, he asked if Brown was surprised by what he saw in Bell Gardens.
