Precise and continuous measurements of atmospheric CO2 concentration were first begun in 1958 and show a clear increase from 315 parts per million by volume (p.p.m.v.)1 then to 345 p.p.m.v. now. A detailed knowledge of the CO2 increase since preindustrial time is a prerequisite for understanding sev...
