From science to solutions: ocean acidification impacts on select coral reefs

Ocean acidification (OA), often called “the other CO2 problem” (Doney et al., 2009), is a consequence of an increased release of anthropogenic carbon dioxide. Man-made CO2 does not only accumulate in the atmosphere, it also dissolves readily in seawater to form bicarbonate ions, thereby releasing protons () and increasing seawater acidity. The acidity of the oceans has increased by about 30% since the beginning of the industrial period, and may increase by more than 150% by the end of the century. This increase in acidity impacts the lives and well-being of many marine organisms and can also disrupt coastal and marine ecosystems and the services they provide.

In October 2008, the Monaco Declaration, drafted at the request of His Serene Highness Prince Albert II, had a global impact far beyond the scientific community. Since this Declaration, the Principality of Monaco and its various institutions (IAEA, CSM, FPA2, IOM1 ) have developed even more intensive work in this field, bringing the Principality of Monaco to the forefront in defending the oceans against this problem. This collaboration took shape in 2015 with the creation of a Monegasque Association for Ocean Acidification (AMAO), bringing together the FPA2, the Monegasque Government, the Oceanographic Institute, the CSM and the IAEA. In September 2019, the Intergovernmental Panel on Climate Change (IPCC) held its 51 session in the Principality of Monaco to launch the Special Report on the Ocean and Cryosphere in a Changing Climate Context (SROCC), which assessed the physical processes and impacts of climate change on ocean, coastal, polar and mountain ecosystems.
