Gov. Brown: "We will protect the precious rights of our people and continue to confront the existential threat of our time — devastating climate change." Brown was sharply critical of Trump during the presidential campaign season on the issue of climate change, taking aim at statements in which the businessman said he's "not a big believer" in the phenomenon. In August, Brown vowed to "vanquish" climate change skeptics. "Bring it on," Brown said at the time. "We'll have more battles, and more victories."
