Okay. 350 is an easy name to remember. But what does it mean?
Scientists around the world are in almost unanimous* agreement: 350 parts per million (350 ppm) of carbon dioxide (CO2) in the atmosphere is the maximum safe limit to maintain life on Earth as we know (and love) it.
The bad news? We’re currently at 410 ppm. And rising.
The good news? We’re part of a global grassroots movement working in multiple ways in multiple countries to bring us (all of us) back from the brink and back on track.
The best news? We’re starting to make a difference. And you can join us.
