Jerry Brown and his predecessor, Arnold Schwarzenegger, this month jointly celebrated the 10th anniversary of California’s war against greenhouse gas emissions. Brown pointed out that Schwarzenegger not only signed the 2006 bill, but also championed two immense public works projects that Brown has adopted as his own. “Arnold, thanks for being for climate change, cap and trade, the tunnels project, high-speed rail and all the other unpopular issues I’m saddled with,” Brown kidded Schwarzenegger.
