Back in August (2021) we talked with Andrew Knoll about the development and forces of our planet based on his recent book, of A Brief History of Earth: Four Billion Years in Eight Chapters. We ran out of time and couldn’t discuss the last –and very important—chapter, “Human Planet” –the story of the Anthropocene. Dr. Knoll very kindly agreed to discuss this topic separately and in this program we take up the Anthropocene and how the November COP26 international meeting underscores the human impact on our planet.
