Film Talk – Feedback Loops: Albedo

Online Event

Organized by Smithsonian National Museum of Natural History

Join us for a virtual screening of the short film Feedback Loops: Albedo.

Watch the film at your convenience upon registration, and tune in on June 9, 2021, for a live discussion with Joellen Russell (Thomas R. Brown Distinguished Chair of Integrative Science and Professor at the University of Arizona in the Department of Geosciences); Sarah Zhou Rosengard (Assistant Professor of Environmental Chemistry, School of the Art Institute of Chicago) and Marika Holland (Senior Scientist and Section Head, Paleo and Polar Climate Research Section, Climate and Global Dynamics Laboratory) moderated by Julianna Olsson(Exhibit Writer and Editor, Smithsonian’s National Museum of Natural History).

This program is offered as part of the 4-part virtual series Natural History on the Big Screen: Feedback Loops, taking place monthly May-August, 2021. Register to receive the screening and Zoom Webinar links.

About the Film: The reflectivity of snow and ice at the poles, known as the albedo effect, is one of Earth’s most important cooling mechanisms. But global warming has reduced this reflectivity drastically, setting off a dangerous warming loop: as more Arctic ice and snow melt, the albedo effect decreases, further warming the Arctic and melting more ice and snow. The volume of Arctic ice has already shrunk 75% In the past 40 years, and scientists predict that the Arctic Ocean will be completely ice-free during the summer months by the end of the century.

This program is a part of the National Museum of Natural History‘s celebration of World Ocean Day focusing on Hope Spots, places that are critical to the health of our ocean around the globe.
