Summary

What’s in a name? “Holocene” defines the geologic epoch we’re in. Or were in? Goodbye to “Holocene” and hello “Anthropocene!” Yes, scientists may actually re-name our geologic era as the “Age of Man” due to the profound impact we’ve had on the planet. We’ll examine why we’ve earned this new moniker and who votes on such a thing. Plus, discover the strongest evidence for human-caused climate change. Also, why cities should be celebrated, not reviled… a musing over the possible fate of alien civilizations … and waste not: what an unearthed latrine – and its contents – reveal about ancient Roman habit and diet. Guests: • William Steffen – Climate scientist and the Executive Director of the Climate Change Institute at the Australian National University, Canberra • Simon Donner – Geographer at the University of British Columbia in Vancouver • Edward Glaeser – Economist, Harvard University, author of Triumph of the City: How Our Greatest Invention Makes Us Richer, Smarter, Greener, Healthier, and Happier • Douglas Vakoch – Director of Interstellar Message Composition at the SETI Institute • Mark Robinson – Director of Environmental Archaeology at the University of Oxford • Erica Rowan – Doctoral student, University of Oxford Learn more about your ad choices.
