Meaning of 350

350 is the number that leading scientists say is the safe upper limit for carbon dioxide in our atmosphere. Scientists measure carbon dioxide in “parts per million” (ppm), so 350 ppm is the number humanity needs to get below as soon as possible to avoid runaway climate change. We reached 400 ppm in 2013.
