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.
