With the UN Climate Summit happening in Copenhagen, 350.org is asking people around the world to start the push to educate and unite on this past weekend of December 12th, with candlelight vigils, marches, and other local action. That’s 350 as in parts per million – the level scientists have identified as the safe upper limit for CO2 in our atmosphere. The 350.org group was started by author Bill McKibben and includes people from all walks of life and all over the world. Inform your staff, student, patrons etc. about 350.org.
