Global climate is a top-of-mind issue for much of humanity. Will our planet become unlivable? What can we do to forestall that possibility? Can we play an active role in saving our planet without massive but inherently fragile globally coordinated action? While answering these questions is difficult, it is impossible without understanding the science. But we only have one world so how do we do that science in a meaningful and predictive way? Join us as Joe Francisco, Guggenheim Fellow and National Academy of Science member, leads us through atmospheric chemistry on Earth and beyond — where modern spectroscopy is allowing us to glimpse climate trajectories of our solar neighbors and what they might have to say about our own pale blue orb’s future.
