Bill McKibbon

Bill McKibben is the author of a dozen books about the environment, beginning with The End of Nature in 1989, which is regarded as the first book for a general audience on climate change. He is the founder of the environmental organizations Step It Up, a grassroots environmental campaign to demand action on global warming by the U.S. Congress; and 350.org , a global grassroots movement to raise awareness of human-caused climate change, to confront climate change denial, and to cut emissions of one of the greenhouse gases, carbon dioxide, to slow the rate of global warming. Since 2009, 350.org has coordinated 15,000 rallies in 189 countries. Time Magazine called him “the planet’s best green journalist” and the Boston Globe said in 2010 that he was “the country’s most important environmentalist.” A scholar at Middlebury College, he holds honorary degrees from a dozen colleges, including the Universities of Massachusetts and Maine, the State University of New York, and Whittier and Colgate Colleges.
