There are zero benefits to these so-called “Net Zero” plans because CO2 cannot be sequestered from the atmosphere, except very temporarily.  The environment will rapidly restore the CO2 equilibrium concentration at any temperature.

Removing CO2 from the environment (or preventing CO2 emission by humans) is a perturbance to the Henry’s Law equilibrium at the location and temperature where the perturbation occurred.  Henry’s Law describes the physical phase-state equilibrium between the unreacted dissolved gas in a liquid, versus the same gas in air or space above the liquid surface and exposed to that surface. Henry’s Law applies to all gas and liquid combinations. Henry’s Law describes atmospheric CO2 gas in contact with the ocean surface, ocean being more than 70% of earth’s surface, but it also applies to water everywhere which is in contact with CO2 gas, for example in and on plants, on humans and all animals and in their lungs, inside bubbles in the ocean, on the surface of rain drops, soil, lakes, and rivers, collectively the environment.

An amount of CO2 gas will be removed from the atmosphere by the environment which is equal to any human-produced CO2 gas emitted to the atmosphere, and vice-versa; this is Henry’s Law simply said.

Thus human-produced CO2 cannot warm the earth.  Any CO2 added by humans will be equally removed by the environment; any amount of CO2 removed by humans will be replaced by the environment. Thus there is no climate emergency based in human CO2 emissions from fossil fuels.  Climate-alarmists are the emergency.

Le Chatelier’s principle and the Law of Mass Action assure us that any perturbance to the Henry’s Law equilibrium will be followed by a rapid response from the environment to restore that equilibrium and the speed and size of that response will be proportionate to the speed and size of the perturbation.  In other words, sequestration or removal of CO2 from the atmosphere or suppression of CO2 emissions, whether by humans, biological activity or inorganic chemical reactions will result in replacement of that CO2 by the environment and restoration of the Henry’s Law equilibrium partition ratio of CO2 gas in water and CO2 gas in air above the water surface based on local surface temperature.

Removing CO2 or preventing emissions of CO2 is a futile waste of money, time and resources.  Humans can neither increase atmospheric CO2 nor decrease it by controlling emissions. 

Ocean and water everywhere will emit an equal or temporarily higher amount of CO2 gas to replace any CO2 gas that has been removed from the environment until the Henry’s Law partition ratio is restored.  The Henry’s Law constant for CO2 and water is a ratio of the molar concentration of CO2 gas in water versus the molar concentration of CO2 gas in air above the water.  The Henry Law constant changes with temperature at the liquid/gas interface, which is dominantly the surface of the ocean. 

Any increase in CO2 concentration in air (due to any CO2 source, natural and human) will be offset by a proportionate increase in solubility of CO2 in ocean and water everywhere that is in contact with the increase in CO2 partial pressure.  This law applies for all gas and liquid combinations, but the ratio is different for each combination and temperature.

CO2 gas is not increasing earth’s surface temperature.  Additions of human-produced CO2 via fossil fuels etc cannot increase earth’s CO2 concentration, therefore human CO2 emissions cannot increase earth’s temperature. Instead, increases in earth’s surface temperature (dominantly ocean surface temperature) cause increases in atmospheric CO2 concentration. And vice versa. Solubility of CO2 gas in water is inversely proportional to temperature of the water. Colder water (thus denser water) holds relatively more CO2 than warmer (and less dense) water. Earth’s surface has been very slowly warming, and thereby ocean surface and water-containing surfaces everywhere have emitted relatively more CO2 than they absorb. Warming of earth’s surface is not due to humans or human-produced CO2, but instead, increases in total atmospheric CO2 are caused by earth’s surface warming. Warming which releases relatively more CO2 gas than is being absorbed. Both emission and absorption occur simultaneously and continuously; the ratio of absorption versus emission is the Henry’s Law constant at the given surface temperature.
