Permafrost, an icy expanse of frozen ground covering one-quarter of the Northern Hemisphere, is thawing. As it does, microscopic animals are waking up and feeding on the previously frozen carbon stored in plant and animal remains, releasing heat-trapping gasses as a byproduct. These gasses warm the atmosphere further, melting more permafrost in a dangerous feedback loop. With permafrost containing twice as much carbon as the atmosphere, its thaw could release 150 billion tons of carbon by the end of the century.

Climate Emergency Feedback Loops, with its captivating illustrations and interviews with leading climate scientists, is a 5-part science documentary narrated by Richard Gere.

This film series is hosted by Physicians for Social Responsibilty Pennsylvania – and is a 5-part Film Club series that includes intriguing panel discussions that explore how human activity is setting off Earth’s own warming loops that are pushing the climate to a point of no return—from the melting ice and snow in the Arctic to the atmospheric jet stream to the thawing of permafrost—and what we can do to stop them.

Join us over the next six months as we delve into the documentary. You can attend one or all of the Film Club sessions detailed below and catch the replay of our first session if you missed it. All sessions will take place from 6 – 7 PM Eastern. After registering, you will receive a link to watch the short documentary clips prior to each session.→ Register for the Rest of the Series Here
