49. Gwynne Dyer on Intervention Earth: climate mitigation, CDR & SRM

Challenging Climate

Our guest is Gwynne Dyer, an author, columnist, broadcaster and lecturer on international affairs. In this episode, we discuss the key messages from his new book Intervention Earth: Life-Saving Ideas from the World’s Climate Engineers, based on extensive interviews with the world’s top climate scientists. We discuss his insights from these interviews on the state of our climate, and address controversies and concerns over carbon dioxide removal (CDR) and solar radiation management (SRM).
