Environmental author and activist Bill McKibben, who launched the Step It Up campaign last year, has revealed the next phase of his plan to fight global warming with local activism. The Brattleboro Reformer reports that McKibben told a group of local activists that this next phase will call for a target of 350 parts per million of atmospheric carbon dioxide. As things stand now we are at about 385ppm and heading upward at about 2ppm per year. He is calling his plan 350. McKibben said that “What we need is people in their own communities to take that number and spread it, with music, with art, and take pictures and get it back into that centralized area.” Unlike his Step It Up campaign which was limited to the United States, this new 350 campaign he envisions as international. McKibben clearly understands the precarious situation that excessive emissions of greenhouse gases from human sources has caused saying that “We are in a big, freaking hole and there’s absolutely no guarantee that we are going to get out of it.” So, it is on to 350.
