As the founder of 350.org, McKibben is building a global grassroots climate movement that can hold our leaders accountable to the realities of science and the principles of justice. He brings with him decades of experience as an author, having written over a dozen books about climate change. In 1989 he wrote The End of Nature, which is regarded as the first book for a general audience about climate disruption.
