(a) Global CO2 emissions from fossil-fuel combustion, cement manufacture, and gas flaring and global population, 1800 – 2014 (sources: carbon emissions data from cdiac.ornl.gov, with years 2012 – 2014 based on data from BP statistical review; population data from CO2 emissions are expressed in millions of metric tonnes of carbon; to convert to the mass of CO2 multiply by the molecular ratio (b) Mean annual CO2 concentration in the atmosphere from two sources: the Law Dome ice-core dataset (Etheridge et al. 1996; MacFarling Meure et al. 2006); and the Mauna Loa Observatory measurements from the Earth System Research Laboratory (source:
