An alternate to my 1982 hypothesis about the driver for the atmosphere’s CO2 content reduction during glacial time was proposed by Wolf Berger, a scientist at Scripps Oceanographic Institution (Berger, 1982). His hypothesis also involved carbon storage in the shallow parts of the ocean but there was a major difference. While I proposed storage in organic matter, he proposed storage of CaCO3. His became known as the coral reef hypothesis. The formation of CaCO3, from waters where HCO3− dominates the inorganic carbon species, releases protons. This increases the concentration of H...
