Writers Bloc and The Los Angeles World Affairs Council & Town Hall present Bill Gates and Don Cheadle. In this urgent, authoritative book, "How to Avoid a Climate Disaster," Bill Gates sets out a wide-ranging, practical—and accessible—plan for how the world can get to zero greenhouse gas emissions in time to avoid a climate catastrophe. Gates joined us live on February 19th, in conversation with climate change activist, philanthropist, and award-winning actor Don Cheadle.
