This episode is the first in a two-part series exploring California's past, present, and future in addressing the existential threat of climate change. In this episode, we talk with UCLA Professor Cara Horowitz about what's at stake as greenhouse gases rise, both globally and in California, particularly in light of a recent report from the Intergovernmental Panel on Climate Change describing the crisis. We also talk with UCLA Professor William Boyd about SB 100, a bill passed last year by the California legislature that commits California to 100% renewable energy by 2045. The bill modifies California's Renewable Portfolio Standard, a regulatory tool that encourages states to procure more renewable resources. Through our conversations in this first part of the series, we get a sense of both the gravity of the climate crisis, as well as one of California's proposed regulatory solutions.
