Since humans began settling down and building civilizations 10,000 years ago, the Earth's climate has been relatively stable. But before that, the climate was more unstable - unpredictable - and humans were nomads, forced to follow the good climate for food and shelter. Today, the global average temperature is higher than it has ever been since the beginning of civilization. What does this mean for the future of human civilization? Could this mean a return to instability? Can we make civilization resilient to such dramatic changes in climate that we have never before experienced as a society?Dr. Spencer Glendon of Probable Futures joins Climate Now to speak about his work to change how we think about, talk about, and plan for the future of society.Follow us on Twitter, LinkedIn, Facebook, and Instagram.Contact us at contact@climatenow.comVisit our website for all of our content and sources for each episode.
