Gen aliye enkyetid yo sou dezasidifikasyon a nan oseyan nan mond lan. Nan 250 lane depi aparisyon nan Revolisyon Endistriyèl la, nivo CO2 atmosferik yo te augmenté soti nan 280 381 pati pou chak milyon dola ak mwayèn lanmè te pH tonbe soti nan 8.16 8.05. Emisyon Imèn-kondwi nan CO2 kontinye ap monte ak yo te kòmanse depase menm ki pi pesimis la nan IPCC senaryo modèl. Kouman yo pral lavi nan oseyan yo adapte yo ak anviwònman k ap chanje sa a? Te patikilye enkyetid te eksprime sou òganis ki gen kokiy lou kalsifye tankou Molisk, menm jan kapasite yo nan ekstrè iyon carbonate soti nan dlo lanmè ak enkòpore sa yo nan vye zo eskèlèt yo ka de pli zan pli konpwomèt.

There is mounting concern over the acidification of the World’s oceans. In the 250 years since the onset of the industrial revolution, atmospheric CO2 levels have risen from 280 to 381 parts per million and average ocean pH has fallen from 8.16 to 8.05. Human-driven emissions of CO2 continue to rise and have begun to outstrip even the most pessimistic of IPCC model scenarios. How will life in the oceans adapt to this changing environment? Particular concern has been expressed over organisms with heavily calcified shells such as molluscs, as their ability to extract carbonate ions from seawater and incorporate these into their skeletons may be increasingly compromised.
