Net CO₂ is the measured amount of total CO₂ in the atmosphere.  Net CO₂ is total CO₂ emitted into atmosphere by all sources (natural and human) minus total CO₂ absorbed from atmosphere by all sinks (natural and human). 

An example of net CO₂ is diligently reported by the Global Monitoring Laboratories (GML) of the U.S. National Oceanographic and Atmospheric Administration (NOAA) such as the laboratory on Mauna Loa volcano on Hawaii Island. (Image below, and at the link below).

This NOAA lab, by general agreement, is the “gold standard” representing a global average for net CO₂ concentration in dry air.  At this lab, the average net CO₂ for 2022 was 418.57 ppm, or 0.0419% of dry air, which is about 419 molecules of CO₂ gas per million gas molecules in air after removing water vapor molecules. 

Net CO₂ is not the amount of human-produced CO₂ in the air.  NOAA is not measuring human-produced CO₂. NOAA measures net CO₂.   

The NOAA-measured average increase in net CO2 was 1.78 ppm for the year 2022. This is the increase over 2021. This rate of annual increase is less than every year since 2009.  That is, the 2022 annual increase in CO₂ due to all sources minus all sinks, natural and human, was 1.78 ppm, or 0.000178% of dry air. 

1.78 ppm divided by 418.57 ppm is 0.4%, which reveals that the annual average increase for the year 2022 in net human-contributed CO₂ did not exceed 0.4% of total atmospheric CO₂ concentration for 2022 and did not exceed 0.000178% of dry air for 2022   NOAA reported uncertainty as 0.12 ppm, which is about 7% of 1.78 ppm (file attached below).

2022 Nobel laureate in physics John Clauser was silenced and cancelled by IMF.   Is there an argument other than the emperors do not appreciate being reminded of their nakedness?
