Cymene and Dominic report from the first week of their trip to China. And then (11:22) we welcome legal scholar Ann Carlson to the podcast to talk to us about battling smog in one of our favorite cities, Los Angeles. Ann has just published a new book, Smog and Sunshine (U California Press, 2026) that tells the remarkable and often inspiring story of how Los Angeles radically improved its air quality. We begin with a reminder of how bad things once were in LA and why. Then we discuss the scientists who helped pinpoint the origins of smog (with an assist from the science of the pineapple of all things) and the oil and automobile industry which tried to suppress the science and deny, diminish and delay action. We turn to comparing the environmental challenges that smog and anthropogenic greenhouse gases pose. Finally, we round things out by examining political polarization around climate action and the importance of government action and attribution science to climate mitigation going forward. Hang in there, everyone, peace and love.
