Global warming, ocean acidification and responses of calcium carbonate producers

Normally, ocean water are saturated with calcium carbonate, but increasing the atmospheric CO2 concentration has led to a decrease in the concentration of carbonate ion and also the pH of seas and oceans. climate change is expected to be associated to an increase of oceanic surface temperature by more than 3 °C and a decrease of global mean sea surface pH up to 0.32 units by the year 2100. Experimental evidences suggest that, as the process progresses, organisms and key organisms in the sea, such as corals and some calcium carbonate planktons, will have difficulty making their required calcium carbonate, and the continuation of this can lead to Destroying these creatures and damaging these ecosystems that will lead to the destruction of a large part of the biodiversity of the water. In this study, while describing the process of CO2 entering aqueous media, we discuss the effects of this process on the physico-chemical properties of water and its consequences for calcium carbonate organisms.
