Atmospheric CO₂ concentration is controlled by Henry’s Law, not by human emission. The dominant variable in Henry’s Law coefficient is ocean surface temperature. The source of CO₂ is not a variable in the CO₂ phase-state equilibrium equation which determines CO₂ gas solubility in ocean water. Ocean surface is 70% of earth’s surface and ocean contains 98% of all water on earth. CO2 is highly soluble in ocean water, especially in cold ocean water. According to most geology and aquatic chemistry textbooks, ocean water contains about 50 times as much CO₂ as atmosphere. The rate (or flux) of CO₂ emissions from ocean surface into air (about 90 billion metric tons CO₂ per year) is controlled by the amount of ocean surface area above 25.6 degrees C (or 78 F). The rate (or flux) of CO₂ absorption into ocean surface (about 90 billion metric tons per year) is determined by the amount of ocean surface area below 25.6 C. These two fluxes (each more than 10 times larger than human CO₂ emissions from all sources) are exchanging CO₂ gas continuously between an estimated 800 billion metric ton CO₂ gas reservoir in the atmosphere and a 1000 billion metric ton aqueous CO₂ gas reservoir in ocean surface. In middle and deep ocean there is another slowly circulating CO₂ reservoir estimated at 40,000 billion metric tons. The ratio of CO₂ gas in air versus ocean surface is determined by Henry’s Law, which is primarily determined by ocean surface temperature. Other factors such as variations in water salinity, alkalinity, and partial pressure are important locally, but average out globally. Human CO₂ emission, volcanic CO₂ emission temporarily push the Henry’s Law partition ratio out of balance, but the equilibrium is quickly re-balanced to the ratio for ocean surface temperature with no permanent offset in the CO₂ concentration or rate of change.  Humans have no control over ocean surface temperature or atmospheric CO₂. Do not waste your money or time on this false agenda.
