Day of Climate Action
October 24. Join the over 1000 communities worldwide who've been organizing for this day. Organize your own action in the place where you live, something that will make 350, that most important number, visible to everyone.
This worldwide campaign focuses on the need to get below 350 parts per million of carbon dioxide in the Earth’s atmosphere, the level considered safe by scientists. (We’re now at about 392 and rising.) This action follows from the successful Step-It-Up Campaign that Bill McKibben initiated in 2007.
