Reactions similar to this one tend to buffer changes in atmospheric CO2.
The right side of the equation indicated that the reaction produces an acidic compound. If adding CO2 to the left side, would decrease the pH of water in ocean. This process is often been described as ocean acidification, where pH of the ocean becomes less and force the pH of water to be acidic.

Rather than this reaction there are other reactions between CO2 and non-carbonate rocks which also add bicarbonate into the oceans. Later on, the reverse of the above reaction will undergo and form more carbonate rocks, then releasing half of the bicarbonate as CO2.

Since most of the CO2 produced by human activities and pumped into the atmosphere will dissolve in the ocean, then

Or rather, change a slightly alkaline ocean into a bit less alkaline. And if continues to happen in the same way, would acidify the water and also lead to warmer oceans. From NASA earth observatory internet resource, described that since 1750, the pH of the ocean’s surface has dropped by 0.1, which is 30 percent in change of acidity.

Ocean acidification cause significant biological impacts. For example the growth rate for shellfish become slower, warmer water temperatures cause coral to expel the algae living in their tissues and turns into completely white, which usually been said as “coral bleaching”.

Now, refer to the effect and impact that CO2 brought to ocean acidification, the reaction of the oceans to increased levels of CO2 may have an effect on how global warming impacts.
From studies published in the journal Nature Climate Change, showed that ocean acidification will make the oceans much less hospitable to many forms of marine life and actually to serve to amplify overall warming.

More importantly, about the other Nature Climate Change study, by some German, American and British researchers, looked that ocean acidification could have effects on atmospheric warming.
The researchers found that as the pH of the oceans dropped, it would result in lower concentrations of the biogenic sulphur compound dimethyl sulphide.

Since marine emissions of biogenic sulphur compound dimethyl sulphide are the largest natural source of atmospheric sulphur, even when sulphur in the form of sulphur dioxide, it isn’t a greenhouse gas, but higher levels of sulphur in the atmosphere can reduce the amount of solar energy reaching the Earth’s surface, which actually causing a cooling effect.

If acidification decreases marine emissions of sulphur, it could cause an increase in the amount of solar energy reaching the Earth’s surface, which speeding up the warming. Refer back to the process of greenhouse effect, where energy is released into Earth’s surface. And now there are more energy will be penetrated through the ozone then to Earth’s surface, relate to the increasing of CO2 or other greenhouse gases, obviously the temperature on Earth’s surface would
