The (mad) science of geoengineering

Climate scientist Ken Caldeira begins with a discussion of ocean acidification, a term he helped coin.  He follows with the story of how his name became attached to geoengineering, from his own skeptical beginnings to publishing a paper that basically said, “well, it works in the models but don’t try this at home.”  Along the way, Caldeira also shares some funny experiences addressing climate skeptics, including how geoengineering has even helped persuade a few.

Masters of the Anthropocene Boundary

It’s our 50th episode!  To celebrate we sit down with four members of the Anthropocene Working Group: the scientists and experts who are deciding whether or not we formally adopt the Anthropocene into the geologic time table.  We discuss what makes the Anthropocene boundary different from all of the other boundaries in geologic history, how they deal with the increased public attention to this particular boundary, and some cultural ripple effects of the Anthropocene dealing with the Law of the Sea.  As we wrap up, the Generation Anthropocene producers take a minute to reflect on all of the rapid changes we’ve witnessed over the past 50 episodes.
