A team of artists and scientists have come together to inspire people around the world to celebrate the sky and save it from climate change. The Sky Day Project is an initiative that combines art and science to teach people how the sky functions and how it can be protected from environmental damage. The project’s founder, Ben Whitehouse, joins us to discuss how the initiative inspires and unites people through sky photography and other art. With him is “Sky Team” member, Daniel Horton, assistant professor of Earth & Planetary Sciences at Northwestern University and a member of Northwestern’s Climate Change Research Group. We’ll also talk to Don Wuebbles, a professor of atmospheric science at the University of Illinois-Urbana-Champaign and lead author for Intergovernmental Panel on Climate Change, astronaut and artist Nicole Stott, and Desa Bolger, a SkyDay volunteer and a senior at Lyons Township High School in LaGrange, Illinois. Sept. 21 has been declared International Sky Day.
