As California lawmakers struggled this week to address an apparent new normal of epic wildfires, there was an inescapable subtext: Climate change is going to be staggeringly expensive, and virtually every Californian is going to have to pay for it. And Californians are being hit with a double-whammy because fighting and preparing for climate change also costs money, and the Golden State has embraced an ambitious agenda to combat global warming. For example, Californians pay more for gas in part because of the state’s low-carbon fuel requirement and the cap-and-trade system that makes polluters pay for their greenhouse gas emissions. “We are right now disproportionately bearing the brunt of both some of the impacts (of climate change) and trying to mitigate it ourselves,” said Solomon Hsiang, Lab co-director and a professor at University of California, Berkeley.
