McKibben took a leap forward in 2007, when he and recent Middlebury College graduates created an organization called Step It Up to educate people about climate change. McKibben had moved his wife and daughter to Vermont several years earlier and Middlebury, which has the oldest environmental studies major in the United States, offered him a position as a scholar in residence. (He now has an endowed position.)
Working on campus, McKibben became interested in a student environmental organization called the Sunday Night Group. “Bill liked the group because it was ‘radically democratic,’ ” says Elder. People could join any time and propose new actions immediately. With a half dozen Sunday Nighters he formed Step It Up, which within three months had engineered 1,400 protests around the country to demand that Congress enact a strong climate bill. Later, the group morphed into 350.org, named for 350 parts per million, their target limit of carbon dioxide in the atmosphere (that level is now around 390, and rising 2 parts per million every year).
