Reducing ocean acidification by removing CO2: Two targets
April 14, 2021ScienceBlog.com
Is it possible to simultaneously address the increase of the concentration of carbon dioxide (CO2) in the atmosphere and the resulting acidification of the oceans? The research of the project DESARC-MARESANUS, a collaboration between the Politecnico di Milano and the CMCC Euro-Mediterranean Center on Climate Change Foundation, explores the feasibility of this process, its chemical and environmental balance, and the benefits for the marine sector, focusing on the Mediterranean basin.
It is now widely recognized that in order to reach the target of limiting global warming to well below 2°C above pre-industrial levels (as the objective of the Paris agreement), cutting the carbon emissions even at an unprecedented pace will not be sufficient, but there is the need for development and implementation of active Carbon Dioxide Removal (CDR) strategies. Among the CDR strategies that currently exist,
