Summary:

Last month, the atmospheric concentration of carbon dioxide (CO2) as measured at Amsterdam Island, in the southern Indian Ocean, for the first time exceeded the symbolic value of 400 ppm, or 0.04%. The CO2 concentrations recorded at the Amsterdam Island research station are the lowest in the world (excluding seasonal cycles), due to the island’s remoteness from anthropogenic sources. The 400 ppm threshold was already crossed in the Northern hemisphere during the 2012/2013 winter. In addition, the increase of CO2 in the atmosphere is speeding up, growing by more than 2 ppm annually over the past four years……..https://www.sciencedaily.com/releases/2016/06/160621094250.htm
