The only thing that is political about the rising level of CO2 in the

They now show that the level is nearly 390 ppm, rather than the 360
ppm quoted by John Hall (IanH)

I certainly didn't quote 360ppm, if only because I couldn't remember the
exact figure and was too lazy to look it up. I think I played safe and
said something like "well under a tenth of one per cent". Someone else
gave the 360 ppm figure.
