Once You Know

On Sunday April 3, our International CUHF gathering brought together Council members and conveners from around the world for an online screening of the award-winning documentary film, Once You Know. The film was followed by a conversation with filmmaker Emmanuel Cappellin, CUHF National Council member Susi Moser, and climate expert Diana Liverman, with breakouts into Council sessions.

In the film, writer/director Emmanuel Cappellin meets with leading climate and energy experts including Susi Moser for profound and personal explorations of what it means to wake up to the realities of climate change and its future impacts. They share the truth, chaos, and hope in their work, and allow him to challenge everything he took for granted — from growth-based democracies to personal freedoms.

Author Ray Scranton describes the film as:

“A beautiful, heart-breaking, and ultimately affirming journey into the grim future we all face. Once You Know confronts our global trajectory of ecological and civilizational collapse and doesn’t flinch or reach for false hope, but helps find a way to live with a truth we cannot unsee.”


Our International CUHF series continues in early Summer 2022. More details will be released soon.
