Anthropogenically released CO2 accumulates in the global carbon cycle and is anticipated to imbalance global carbon fluxes. For example, increased atmospheric CO2 induces a net air-to-sea flux where the oceans take up large amounts of atmospheric CO2 (i.e., ocean acidification. Research on ocean acidification is ongoing, and studies have demonstrated the consequences for ecosystems and organismal biology with major impacts on marine food webs, nutrient cycles, overall productivity, and biodiversity.
