Link here.

June, 2018: 410.79
May, 2019: 414.83
May, 2018: 411.31

3.14 units per million = 3.14 / 1,000,000 = 0.000000314 =0.0000314%. Okay.

If you drew a graph with the y axis from  zero to 10,000, with the x axis for the last ten years the line would be flat.  Just saying. The concentration of CO2 in the Venetian atmosphere, 96.5% or 965,000 ppm.
