I haven’t done a chart or graph in a while, so here’s a new one.

The big pale blue circle represents the Earth’s atmosphere.

The yellow circle represents the level at which CO2 levels (as a percentage of the overall atmosphere) are considered toxic.

The pale green circle represents the average levels of CO2 in the atmosphere during the Jurassic period.

The blue circle represents the average level of CO2 in the atmosphere in 2009.

The red circle represents the amount of CO2 produced by man since the beginning of the Industrial Revolution.
