Is Jerry Brown taking Trump’s place on world climate stage?

Three months before Donald Trump launched his improbable presidential campaign, one in which he dismissed climate change as a “hoax” and a “very, very expensive form of tax,” Gov. Jerry Brown was touting California’s collaborations with China on air pollution, clean energy and low-carbon development.

“It is a little bold to talk about the China-California partnership as though we were a separate nation, but we are a separate nation,” Brown said of the state, with nearly 40 million residents and the world’s sixth-largest economy. “We’re a state of mind. I include Silicon Valley, I include the environmental activism, the biotech industry, agriculture. This is a place of great investment in innovation.”
