We had a similar observation and related feelings — cooling towers move, quite literally, tons of air every day.

One suggestion I'd make to the math above: the concentration of CO2 in the air is a bit higher, at 415ppm per Scripps UCSD: https://www.co2.earth/

Yeah, I was going to say, it hasn't been 385 since about 2008.
