This is the third time I've tried to start a discussion about global warming. The first time my topic ended up in the “acid” section, the other two times in the “Black Sea” section. I continue to try to frame the discussion in the "global warming" thread.

Each time I lowered the level of discussion.

My presentation on this topic does not open on the site and this is the reason for opening the discussion.

Along with global warming, there are other reasons for changes in sea levels. One of these reasons is a change in the morphometric characteristics of the World Ocean due to the “fallout” and “melting of carbonate snow” in the thickness of the bottom sediments of the World Ocean. The direction of this continuous process is regulated by the acidity of the waters of the World Ocean, which in turn depends on the ratio of the partial pressure of carbon dioxide in the atmosphere and the surface layer of the ocean and on the intensity of the release of acidic fluids from the lithosphere in the bottom and deep layers of the World Ocean.

Carbon dioxide dissolving in water increases its acidity, and acidic waters dissolve carbonates contained in bottom sediments.

Maps are provided (http://earthtrends.wri.org/updates/node/245) reflecting the dynamics of changes in the content of aragonite in the bottom sediments of the World Ocean over the past 230 years. The volume of aragonites became smaller. The ocean became deeper. The water level in the ocean has dropped.

This is written about in my monograph “Modern changes in the level of the Black Sea as the basis for the strategy of construction development of the coasts”.

Look how much CaCO3 can be dissolved by acidic sea water in a coral reef. This photo is from my discussion "Why does a bay in a coral reef coincide with a submarine discharge of acidic groundwater?".
