Climate change is one of the greatest global challenges of our time. October 27 at 8 pm ET, join NASA astronaut Jessica Meir in conversation with scientists from NASA's Goddard Space Flight Center and the Smithsonian’s Movement of Life Initiative to discuss their complementary expertise and the role of space and aviation technologies in studying our changing world. From tracking long-distance animal migrations to mapping global carbon cycles, these specialized tools have catalyzed new understanding of climate change, our Earth, and its interrelationship with the species that call it home.

This series is part of the Smithsonian Conservation Commons’ Earth Optimism initiative, a global movement which aims to further research and discussion of climate change through identifying, sharing, and promoting solutions to this global crisis. Earth Optimism aims to build a broad, international community of action to conserve our most precious resource—a habitable Earth.
