This side event, organized during the United Nations Conference on Climate Change 2014 (COP20) in Lima, will provide an overview of the impacts of ocean acidification on marine ecosystems and on the services they provide.
Marine and coastal biodiversity – ecosystems, species and genetic material – provide enormous benefits for human well-being. Hundreds of millions of people rely directly on marine biodiversity for their livelihoods and food supply. The ocean is also critical to many important Earth system processes, playing a key role in climate regulation and nutrient cycling, among others.
However, the global ocean is facing a major threat from human-driven changes in atmospheric composition. Increasing concentrations of carbon dioxide (CO2) reduce seawater pH and have other effects on ocean chemistry, compromising the health of ocean ecosystems and their ability to provide important services to human society. As a slow-onset event, the impacts of ocean acidification are beginning to be felt in some areas; future projections indicate even more broad-reaching deleterious impacts, with climate change interactions, if action is not taken now. For example, the loss of tropical coral reefs will increase coastal erosion, greatly worsening impacts of sea level rise
Current efforts to understand the ecological and socioeconomic consequences will be presented during the event. An expert panel will review the main global efforts to improve our understanding of ocean acidification and outline options to reduce its impacts.
