PH la nan oseyan an sifas te tonbe pa 0.1 inite pH depi nan konmansman an nan Revolisyon Endistriyèl la. ref Pandan ke sa a pa ka son tankou yon anpil, echèl la pH se logaritmik, ak chanjman sa a reprezante yon ogmantasyon 30% nan asidite. Kòm oseyan yo kontinye absòbe CO2 , yo pral vin de pli zan pli plis asid. Oseyan pH la projetée lage yon 0.4 adisyonèl pH pa 2100 anba yon CO segondè2 senaryo emisyon, ref ak nivo saturation carbonate potansyèlman tonbe pi ba pase sa yo mande yo pou soutni accrétion Reef koray. ref Chanjman sa yo nan chimi kabòn nan lanmè a louvri pwobableman pa te fèt pou plis pase 20 milyon ane. ref

The pH of the surface ocean has fallen by 0.1 pH units since the beginning of the Industrial Revolution. ref While this may not sound like a lot, the pH scale is logarithmic, and this change represents a 30% increase in acidity. As the oceans continue to absorb CO2 , they will become increasingly more acidic. Ocean pH is projected to drop an additional 0.4 pH units by 2100 under a high CO2 emission scenario, ref with carbonate saturation levels potentially falling below those required to sustain coral reef accretion. ref Such changes in the carbon chemistry of the open ocean probably have not occurred for more than 20 million years. ref
