Los Angeles was once defined by smog that for decades choked the city with toxic haze. It obscured surrounding mountains and exposed people – especially children – to dangerous levels of lead, carbon monoxide and other pollutants. But by the early 2000s, thanks to steady public pressure and government reforms, the region’s air transformed. We talk to UCLA’s Ann Carlson about what L.A. can teach us about confronting climate change now, as the Trump administration rolls back emissions standards. Her new book is “Smog and Sunshine: The Surprising Story of How Los Angeles Cleaned Up Its Air.”
