The crucial question for you guys should be, however, when did the industrial revolution reach such levels, that the industrial CO2 output reached any significant levels? I know this chart is a very simple one but did you look at it closely? Its very clear about the build up of CO2. It starts in the mid 18th century; slowly accelerates through the 19th century; by 1900, breaks past what had been previously the upper most limit of CO2 concentration in the atmosphere for thousand of years: 300 PPM; and then really starts to take off around 1950. powerpoints.wri.org
