Share The DESARC-MARESANUS project, a collaboration between the Politecnico di Milano and the CMCC Euro-Mediterranean Center on Climate Change Foundation, addresses two serious environmental problems: the increase of the concentration of carbon dioxide (CO2) in the atmosphere, with the consequent increase in temperatures, and the acidification of the oceans, which destabilizes the ecosystem and threatens vital ecosystem services. To counter these problems, it is necessary to develop and implement active Carbon Dioxide Removal (CDR) strategies, which also address ocean acidification: artificial ocean alkalinization via the dissolution of Ca(OH)2, known in short as ocean liming, has attracted attention due to its capability of contemporarily addressing two issues.
