All around the world communities are taking action to spread the number 350, the safe level of co2 in the atmosphere measured in parts per millions (ppm), and make sure world leaders are on course to reach that target.
We're already at 385, so it's urgent that we act together and build a movement that will get the job done and ensure a safe and just future for the world.
Please join and help build this movement: 350.org
