Harvard’s Professor David Keith might just be the world’s foremost solar geoengineering researcher. He talks to Climate Futures about the extraordinary plan to inject sulfur into the stratosphere and cool the planet. This plan might save hundreds of thousands of lives - but does it also imperil our relationship to nature? Professor Keith explains the ideas behind solar geoengineering and thoughtfully considers the ethical and political questions it raises. David Keith’s book A Case for Climate Engineering can be found here, on Amazon, at your local library, or wherever you buy books. Music in this episode is Podington Bear’s Blue Highway and John Harrison with the Wichita State University Chamber Players’s Winter Mvt 1 Allegro non molto. Logo by Noelle Chung.
