Climate scientist Dr. Katharine Hayhoe — Nature Conservancy chief scientist, Texas Tech professor and author of "Saving Us" — joins Joel and Solitaire to explain why hope beats doom as a climate strategy, why more disasters don't produce more action, and the one underrated lever she'd hand a Fortune 500 CEO instead of another renewable-energy announcement.

What can climate communicators learn from stand-up comedians? Quite a lot, it turns out. Joel Makower and Solitaire Townsend sit down with Stuart Goldsmith — climate comedian, podcaster, and Live at the Apollo veteran — and Esteban Gast, the Colombian-American comedian behind the Climate Comedy Cohort. They talk about performing for hostile rooms, the power of vulnerability, why hypocrisy is the best material, and why treating your audience like friends might be the most underrated tool in climate communications.

Soli and Joel ask an uncomfortable question:sustainability professionals are trained to track trends and build momentum —but are we actually prepared for wild cards?

We went through some big ones: a 90% probability El Niño that most supply chains aren't pricing in, a data center oppositionmovement that's blocked $18 billion in U.S. projects, an insurance exodusthat's quietly making whole communities uninsurable, and the reality that social movements — for and against sustainability — are among the most powerful forces shaping corporate behavior.

As Soli put it: This is literally our job. And we're not doing it.
