California's political leaders pledged Monday to advance the state's landmark laws on climate change and fend off challenges from opponents such as oil companies.
"We're just at the beginning," Gov. Jerry Brown said. "There's still lots of skeptics and lots of deniers."
Brown and top lawmakers spoke at a conference hosted by Tom Steyer, a major Democratic donor who has wielded his financial clout to urge action on climate change, and the event was a mix of wonky policy discussions and pep rally speeches.
