Fantastic podcasts- Earth and Environmnetal systems

I am working my way through Dr Christian Shorey's wonderful series of podcasts Earth and Environmental Systems. The more I listen to them, the more respect I have for the entire series. All the geological systems podcasts are great for landscape architects who need to know how the various hydrological, atmospheric and geological processes work. I am currently enjoying the history of the human species podcasts - these history podcasts connect our lives and the earth systems beautifully, so they are also really relevant for landscape architects (and everyone). Of course, the use of systems thinking to analyse everything makes these a must-listen.
