Is This Too Good To Be True?
Because oceans are alkaline (pH 8.1), they absorb all carbon dioxide from the air, but salt drives out one third the amount of CO2 plants need to grow on. Without salt in the oceans there would not be enough CO2 in the air for plants to grow on.
On a long term basis, CO2 is tied up in the oceans as calcium carbonate in coral reefs. Propagandists claim that increased carbon dioxide is destroying coral reefs by causing the oceans to become more acidic. There has been no measurable increase in acidity of the oceans, because the amount humans produce is miniscule compared to the ocean's capacity. The surface oceans contain 1,000 GTC, and it does not stay there. It circulates into the deep oceans, and it gets used in producing coral reefs. The intermediate and deep oceans contain 38,000 GTC. Humans add 8.5 GTC to the air per year.
A new study and web site explains the oceanography of carbon dioxide and shows the errors of the propagandists who claim that increased CO2 in the oceans will make the oceans more acidic and destroy coral reefs. Near the surface of the oceans, increased photosynthesis creates alkalinity rather than acidity. There is in fact a shortage of acid near the surface for the promotion of photosynthesis. The decay which creates acidity occurs 1-2 kilometers down, which is way below the level of coral reefs.
