350

350 parts per million (ppm) is the safe level of carbon dioxide in our atmosphere. We surpassed 400 ppm this past March. The last time CO2 levels were this high, humans didn’t exist.

350 is a climate change organization that utilizes grassroots organizing, online campaigns and political action to demand climate change.

The 350 Effect is a capital campaign to build a West Coast hub for operations for 350 as they continue to expand in over 188 countries and to widen its reach.
