Introduced by David Orr.

As Bobby Kennedy Jr. said, “Dr.James Hansen is Paul Revere to the foreboding tyranny of climate chaos – a modern-day hero who has braved criticism and censure and put his career and fortune at stake to issue the call to arms against the apocalyptic forces of ignorance and greed.” Among the world’s top climate scientists, Dr. James Hansen describes the dire urgency for dramatic global climate action, including the immediate end to new coal plants. Since 1981 he has served as head of the NASA Goddard Institute for Space Studies, and is an Adjunct Professor in the Department of Earth and Environmental Sciences at Columbia University. He will share his personal odyssey into climate action, including civil disobedience.

This speech was presented at the 2010 Bioneers National Conference.
