Journalist Dahr Jamail explains why saving what’s left of life on the planet is a moral calling we can’t leave to governments, what large-scale biophysical changes our environments will experience as the Earth’s ice melts away, and how everything must change within ourselves if we’re to survive this new world we’ve created through a history of destruction.

Dahr is author of the book “The End of Ice: Bearing Witness and Finding Meaning in the Path of Climate Disruption” from The New Press.
