evidences.evidence_id: Carbon dioxide:204
evidences.article: Carbon dioxide
evidences.evidence: As the concentration of carbon dioxide increases in the atmosphere, the increased uptake of carbon dioxide into the oceans is causing a measurable decrease in the pH of the oceans, which is referred to as ocean acidification.
