The Most Important Number in the World | April 13, 2009

Science has given us, in the last 18 months, a real bottom line for the planet: a CO2 concentration above which, as NASA's Jim Hansen has put it, we can't maintain the "planet similar to that on which civilization developed and to which life is adapted." We need a movement to get that scientific truth across to as many folks as possible.


Bill McKibben

Our guest speaker is Bill McKibben, a scholar in residence at Middlebury College, an American environmentalist and prolific writer on related topics. In summer 2006, he led the largest demonstrations against global warming in American history.
