What does 350 mean?
350 represents a "safe" target for the amount of carbon dioxide in our atmosphere in parts per million (ppm). About a year ago, a climate experts suggested that if we let the amount of carbon in the atmosphere top 350 parts per million, we will no longer have a planet "similar to the one on which civilization developed and to which life on earth is adapted."
Our atmosphere is currently at 390 ppm and rising fast. The effects of this on our natural climate system are evident though hotter temperatures, rising sea level, shifting rainfall patterns, stronger storm events, ocean acidification, among other impacts. 350 represents a clear, definite target that the whole world can aim for in order to stop climate change. People from around the world will be taking action on October 24 to help capture the attention of the media and global leaders regarding the importance of 350 ppm as a target for the emissions reductions talks occurring in Copenhagen this December.
