The 350 ppm CO2 target is the focus of an international campaign announced today in several media by the Tällberg Forum. This is the follow-up to the objective proposed by the NASA Chief Scientist James Hansen and his colleagues to limit the concentration of carbon dioxide in the atmosphere to 350 ppm (parts per million). The goal is to avoid global climate change with potentially very large and irreversible effects on human society and the natural environment.
