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 nor 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 0.000258%. Measured by NOAA-Scripps Oceanographic. This means for 2020 the net amount of CO2 from humans could not have exceeded 0.000258% of the atmosphere, and was probably much less. The maximum possible amount of net human CO2 as a percent of net global CO2 for 2020 could not have exceeded 0.6%.
It is the maximum possible net amount of CO2 emitted by humans because that amount includes CO2 emissions from all sources and CO2 absorption by all sinks. 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.) The “net amount” of CO2 means total CO2 absorption subtracted from total CO2 emission. The difference is the net increase (or growth) in net CO2 from 2019 to 2020, which was only 0.000258%. Thus for 2020 net human CO2 increase cannot exceed and must be less than 0.00025% of atmosphere and less than 0.6% of total CO2.
Consulting firm McKinsey & Co., supported by the UN, WHO, WEF, the governments of over 150 countries, many world bankers, and most mainstream media, and most academic institutions want you to spend $9 TRILLION dollars per year each year for decades into the future because they claim without proof that human CO2 emissions are dangerous.
There is no real-world evidence from the environment that so-called renewable or sustainable energy reduces net global CO2 concentration, nor does renewable or sustainable energy reduce global warming or climate change. There is strong engineering evidence that net zero CO2 emissions is impossible, deadly dangerous, and financially unaffordable. Climate modelers admit their models are wrong. It is a scam. You are their sucker. Would you like some snake oil along with your scam? You will either push back, or they will separate you from your property and your sovereignty.
Climate fraudsters have been building their scam for over 50 years. The laughably absurd response by proponents of the scam include only ad hominem efforts to change the subject, offered by so-called climate scientists (really computer gamers), along with attacks on the messengers who now number in the many thousands.
