Bill McKibben is founder and senior adviser emeritus of 350.org. His 1989 book The End of Nature is regarded as the first book for a general audience about climate change and has appeared in 24 languages. He has gone on to write many more books, and his work appears regularly in periodicals from the New Yorker to Rolling Stone. He serves as the Schumann Distinguished Scholar in Environmental Studies at Middlebury College and as a fellow of the American Academy of Arts and Sciences. He has won the Gandhi Peace Prize, honorary degrees from 19 colleges and universities and was awarded the Right Livelihood Award, sometimes called the alternative Nobel, by the Swedish Parliament. Foreign Policy named him to its inaugural list of the World’s 100 most important global thinkers.

McKibben helped found 350.org, the first global grassroots climate campaign, and has organized on every continent, including Antarctica, for climate action. He played a leading role in launching the opposition to big oil pipeline projects, and the fossil fuel divestment campaign, which has become the biggest anti-corporate campaign in history, with endowments worth more than $15 trillion stepping back from oil, gas and coal. He stepped down as board chair of 350.org in 2015 and then left the board in 2020, accepting emeritus status.
