Our Guests

Our speakers showcase the full spectrum of diverse voices and powerful perspectives. Political figures like Gina McCarthy and Steve Schmidt have inspired and provoked. Executives like former British Petroleum CEO Lord John Browne and Enbridge SVP Mike Fernandez have surprised and challenged. Psychologists like Renee Lertzman, economists like Nicholas Stern and Mark Carney, and scientists like Ayana Elizabeth Johnson and Katharine Hayhoe have expanded our notions of what climate change means for us as people and a society. We’re constantly adding more perspectives to our empowering conversations.
