Summary: <p><span class="caps">ENCORE</span> 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.</p> <p>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.</p> <p>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.</p> <h2>Guests:</h2> <ul> <li> <strong><a href="">William Steffen</a></strong> – Climate scientist and the Executive Director of the Climate Change Institute at the Australian National University, Canberra</li> <li> <strong><a href="">Simon Donner</a></strong> – Geographer at the University of British Columbia in Vancouver</li> <li> <strong><a href=""> Edward Glaeser</a></strong> – Economist, Harvard University, author of <i><a href=";tag=arweal-20&amp;linkCode=as2&amp;camp=217145&amp;creative=399369&amp;creativeASIN=159420277X">Triumph of the City: How Our Greatest Invention Makes Us Richer, Smarter, Greener, Healthier, and Happier</a><img src=";l=as2&amp;o=1&amp;a=159420277X&amp;camp=217145&amp;creative=399369" width="1" height="1" border="0" alt="" style=""></i> </li> <li> <strong><a href=""> Douglas Vakoch</a></strong> – Director of Interstellar Message Composition at the <span class="caps">SETI</span> Institute</li> <li> <strong><a href="">Mark Robinson</a></strong> – Director of Environmental Archaeology at the University of Oxford</li> <li> <strong><a href="">Erica Rowan</a></strong> – Doctoral student, University of Oxford </li> </ul><p><strong><a href="">Descripción en español</a></strong></p> <p>First released October 24, 2011</p>
