Humans inhale air of ~78% N2 gas, ~21% O2 gas, a variable % water vapor gas, and many trace gases including 0.09% argon gas, ~0.04% CO2 gas, etc. Then humans exhale ~78% N2, ~16% O2, a variable % of water vapor gas, ~0.09% argon, and ~4% CO2. In other words, humans exhale CO2 that is about 100 times more concentrated than the air they inhaled a moment before. Where does that CO2 go?
The measured, not computer modeled, not estimated, net increase of CO2 from all sources, combining all human CO2 sources and sinks and all natural CO2 sources and sinks, for 2020 was only 0.000258% of the atmosphere. Measured by NOAA-Scripps Oceanographic, publicly available data (1) (2020 data are used here because 2021 data have not been finalized.) This means for 2020 the net amount of CO2 added to the atmosphere by humans (including fossil fuel use, cement production, land use, breathing, etc) could not have exceeded 0.000258% of the atmosphere and was probably much less. Then 2.58 ppm net global average increase for 2020 divided by 414.24 ppm net global average CO2 concentration is 0.6%. The maximum possible average net human CO2 addition to the atmosphere for 2020 could not have exceeded 0.6%.
It is the maximum possible net CO2 emitted by humans because that amount includes CO2 emissions from all sources and CO2 absorption by all sinks, both natural and human. CO2 is always, day and night, everywhere, (24 hours X 365 days per year) being absorbed by the environment, mostly ocean surface and plants, and simultaneously always being emitted. (CO2 gas is continuously colliding with ocean surface, which is ~71% of Earth’s surface. CO2 gas is highly soluble in water and ocean. All decaying biological material is emitting CO2. CO2 is highly soluble in water and sea water.) “Net” CO2 means CO2 absorption subtracted from CO2 emission. Subtracting the CO2 concentration of 2019 from the CO2 concentration of 2020, results in on 2.58 ppm or only 0.000258% of the atmosphere on average. Thus, for 2020 net human CO2 addition to the atmosphere cannot exceed and must be less than 0.000258% of atmosphere and less than 0.6% of total CO2.
According to NOAA’s measurements, for year 1970, net CO2 in air from all sources and sinks was 325.68 ppm. That was a net increase from 1969 of 1.06 ppm due to all sources and sinks, natural and human. For 2020, net CO2 in air from all sources and sinks was 414.24 ppm, an increase of 2.58 ppm from 2019, due to all CO2 sources and sinks, natural and human. That is 0.000258% increase in CO2 for 2020. Subtracting: 414.24 minus 325.68 equals 88.56 ppm, which is the measured net CO2 increase in 50 years, for a 50-year average of 1.77 ppm per year increase, due to all sources and sinks, natural and human. That is a 0.000177% per year average increase. Remember your exhaled breath is ~4% CO2 with each exhaled breath, higher if you are exercising. Net CO2 due to all sources and sinks has grown only 27% in 50 years, 88.56 ppm, which might sound like a lot, except remember it is starting from a very low CO2 concentration; for 1970 CO2 was 325.68 ppm.
In the graph below, the red line is approximately 1% representing the sum of all rare gases in air. Beneath that is the purple line which graphs the net global average CO2 concentration from 1970 to 2020 computed and reported by NOAA, 325.68 ppm in 1970 to 414.24 ppm in 2020; these data are not detrended. Beneath that is the dashed green line which graphs the annual CO2 increase, the net of all CO2 sources and CO2 sinks, from 1.6 ppm per year for 1970 to 2.58 ppm per year for 2020, which is the maximum possible human emissions for each year.
“The threshold for plant survival is 150 ppm, CO2 fell to 180 ppm during the most recent glacial maximum 20,000 years ago.” (2) The ONLY way CO2 gets into plants for photosynthesis is by absorbing CO2 from air. Plant photosynthesis produces carbohydrates which feed all life on earth and in the process produce oxygen as a by-product. Late Carboniferous to Early Permian time (315 mya — 270 mya) is the only known time-period in the last 600 million years when both atmospheric CO2 and temperatures were as low as they are today (Quaternary Period). In the lush and abundant life of the Triassic and Jurassic Periods, a period over 100 million years long, CO2 is estimated to have been 4 and 5 times higher than 1970.
Billions of dollars just foolishly and ignorantly passed into U.S. law by Democrats, as well as the $9 TRILLION per year estimated by McKinsey & Co, global bankers, Foreign Affairs Magazine, State Department, EPA, academics living on government grants, UN, WHO, EU, WEF, politicians in over 150 countries, computer gamers masquerading as climate scientists, complicit mainstream media, Greta, Gore, etc., the amount they claim is needed to control human-produced CO2, all of that is a fraud, a total and tragic waste of resources. And this fraud has been ongoing for over 50 years.
It is ludicrous to believe that CO2 is the temperature control knob for the Earth, as claimed by the United Nations. But, on top of that, there are the impossible economics and engineering which are proposed, being built and installed today to transition from a productive fossil-fuel-powered economy to an impossible dystopian future fantasy world that will fail, as described below. This travesty continues because people fall for the mantra of fear propaganda, continue to elect politicians who support it, and allow teachers to teach it.
Only concerned voters and parents can stop this fraud.

I believe the threshold for plant survival is 150 ppm, not 250 ppm. CO2 fell to 180 ppm during the most recent glacial maximum 20,000 years ago.
Thanks for the correction Patrick.
