Everyone has heard about global warming, but few understand how environmental feedback loops amplify the warming even further. With captivating illustrations and interviews with leading climate scientists, this 5-part science documentary and panel discussion series explores 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 Physicians for Social Responsibility Pennsylvania for five intriguing panel discussions over the next six months as we delve into the Climate Emergency: Feedback Loops. Technology hosted by Halt the Harm.

May 19, 2022: Introduction
Fossil fuel emissions from human activity are driving up Earth’s temperature—yet something else is at work. The warming has set in motion nature’s own feedback loops which are raising temperatures even higher. The urgent question is: Are we approaching a point of no return, leading to an uninhabitable Earth, or do we have the vision and will to slow, halt, and reverse them?
