This episode is the second in a two-part series exploring California's past, present, and future in addressing the existential threat of climate change. In this episode, we explore California's entrée as a global leader on climate change with UCLA Law Professor Cara Horowitz, especially following the 2018 Global Climate Action Summit, an international climate conference spearheaded by former California Governor Jerry Brown. We also discuss some of the critiques of the Summit and of Governor Brown's environmental policies, particularly from environmental justice groups in California. Finally, we talk with Jessie Cammack, a 3L student at UCLA Law, about her research on the potential vulnerability of California's international climate actions to the dormant foreign affairs preemption doctrine.
