New Documentary Explores How Environmental Feedback Loops Are Amplifying Global Warming and Issues an Urgent Call to Action

While everyone may have heard of global warming, few understand or know about environmental feedback loops, which are amplifying and accelerating the process. In EARTH EMERGENCY, climate scientists explain how warming caused by human activity is setting in motion Earth’s own natural mechanisms, releasing additional greenhouse gases into the atmosphere, and further heating up the planet. This revealing film uses captivating illustrations and graphics, stunning footage, and interviews with leading scientists to examine this crucial piece of the climate puzzle. The film conveys the urgency of stopping these cycles, letting natural systems remove carbon and preserving the delicate balance necessary to maintain Earth’s temperature. Narrated by Richard Gere and featuring the Dalai Lama and Greta Thunberg, EARTH EMERGENCY premieres on Wednesday, December 29, 8-9pm ET. Please check your local listings on and the PBS Video app.

“Most people I know or encounter haven’t even heard of feedback loops or tipping points,” says Greta Thunberg. “But they are so crucial to understanding how the world works. We have such lack of respect for nature and for the environment. We just think that things will work out in the end. But we cannot solve the climate emergency without taking these feedback loops into account and without really understanding them. So that is a crucial step.”

Out of dozens of environmental feedback loops, EARTH EMERGENCY focuses on four, explaining how warming in forests, permafrost, the atmosphere and the poles work together to accelerate dangerous, amplifying cycles. Despite these feedback loops pushing the climate to a point of no return, they are not generally understood by the public—or many policymakers.

Recently, because of its compelling presentation of feedback loops, EARTH EMERGENCY was presented to the Members of the House of Parliament and by HRH Prince Charles as part of his COP26 Glasgow presence at the Terra Carta Action Forum at Kelvingrove Art Gallery and Museum in Glasgow on November 4, 2021.

The Smithsonian National Museum of Natural History held a summer film & discussion series based on the film. The program has begun to be broadcast on television stations around the world. Even astronauts at the International Space Station will be able to watch the program while gazing down at our planet.

EARTH EMERGENCY will stream simultaneously with broadcast and be available on all station-branded PBS platforms, including and the PBS Video app, available on iOS, Android, Roku, Apple TV, Amazon Fire TV, Android TV, Samsung Smart TV and Chromecast.

Narrated by Richard Gere, EARTH EMERGENCY is directed and co-written by Susan Gray. The senior producer and writer is Bonnie Waltch and Barry Hershey is the producer.
