UNGA, Advise & Consent, Democratic Data
Sirens (should Sirens just be a book pod?) starts with the best question: if you could only read one book for the rest of your life, what would it be? On the cocktail party circuit, we had to discuss the Great Gathering of Gobsmacked GOFOs, plus how the US gave up AI norms at UNGA and changes to social security. Amid Dumpster Fires aplenty, we dig into chaotic reforms to H1B visa and the consequences to the economy and national security, as well as the nuclear change to senate nominations process. In Warning Signs, we welcome former US Chief Data Scientist Denice Ross for a wonderful discussion on the federal data system and democratic accountability. And Gong Show? We had no choice: Robert Redford. It's the fall that's gonna kill you.

Sirens at Climate Week Live!
Americans want a government that is agile, responsive, and able to deliver basic services while also solving complex challenges like climate change. Yet the climate community tends to over-focus on questions of climate policy design rather than questions of climate policy implementation — resulting in ambitious efforts like the Inflation Reduction Act that held great promise on paper but ran into roadblocks in the real world. In this live taping, host Loren DeJonge Schulman is joined by special guests Carol Browner, former U.S. EPA Administrator, Jordan Diamond, Executive Director of the Environmental Law Institute, and Nancy Metayer Bowen, Vice Mayor of Coral Springs, FL, to discuss why government capacity is the overlooked engine of climate progress — and explore how civic leaders, lawyers, and public innovators are tackling procedural bottlenecks, modernizing outdated systems, and strengthening the connective tissue between federal, state, and local actors to unlock faster and more durable climate outcomes.
