We’ve accomplished a lot in our first 10 years, but we’re just getting started! Join us as we continue to work to ensure a safe, livable planet for future generations.
The number 350 means climate safety: To preserve a livable planet, scientists tell us that 350 parts per million (ppm) is the safe upper limit for carbon dioxide (CO2) in the atmosphere. Unfortunately, the concentration of CO2 in the atmosphere is currently above 420ppm and is rising 2–3ppm every year. This continuing increase risks reaching tipping points and irreversible impacts such as the melting of the Greenland ice sheet and major methane releases from increased permafrost melt.
