StarTalk Radio –NASA’s Former Chief Scientist on Climate in the Solar System: Earth to Venus, Mars, Titan’s Ice Volcanoes & the Anti-Greenhouse Effect



Dr. Ellen Stofan, former Chief Scientist at NASA, who has been involved with numerous interplanetary spacecraft missions, including the Magellan spacecraft, leads a discussion on Earth’s climate: using space exploration to talk about climate change; the impact of climate change on human health; applying climate models to other planets, volcanoes) and their climatic impact; and much more.

Explore Ellen’s favorite celestial body in the solar system, Titan (atmosphere images above), including the geological mechanics of Titan’s ice volcanos, and what David call’s Titan’s “anti-greenhouse effect.” You’ll also hear about geoengineering and why David and Ellen say there are easier ways to solve the climate crisis.

Plus, cyanobacteria, biomimicry, and the environmental ethics of our solar system. They also answer fan-submitted Cosmic Queries ranging from, “Could we use Mars and other planets as a dumping ground for trash and nuclear waste?” to “Is there any way to reverse global warming?”
